- 2010
-
In: Clinical Transplantation. - : Wiley. - 1399-0012 .- 0902-0063. ; 24:4, s. 500-509
-
Journal article (peer-reviewed)abstract
- The Symphony study assessed whether mycophenolate mofetil (MMF)-based regimens containing reduced doses of adjunct immunosuppressants could reduce toxicity while maintaining efficacy. Here, we examined the impact of acute rejection and associated risk factors. The incidence of biopsy-proven acute rejection in the low-dose tacrolimus group was approximately half that of the standard-dose cyclosporine and low-dose cyclosporine groups, and a third of that in the low-dose sirolimus group. The low-dose cyclosporine group had more severe rejection episodes (>= grade II) compared with other groups. Acute rejection was associated with a 10 mL/min glomerular filtration rate (GFR) reduction and a 5.3% absolute increase in graft loss at 12 months. Overall, the highest GFR was found in both rejecters and non-rejecters receiving low-dose tacrolimus, both in an intent-to-treat analysis and in patients successfully treated according to the protocol. In Cox regression models, human leukocyte antigen (HLA) mismatches and expanded criteria donors increased the acute rejection risk, while recipient age, living related donor, and MMF dose were associated with a reduced risk. Acute rejection was associated with worse outcome but did not entirely explain the differences among the treatment groups. The 2 g MMF plus low-dose tacrolimus combination appears to be the most efficient of all regimens examined regardless of acute rejection.

Recently accepted for the waiting list for heart or lung transplantation - patients' experiences of information and support.
- 2011
-
In: Clinical Transplantation. - : Wiley. - 1399-0012 .- 0902-0063. ; 25, s. 664-671
-
Journal article (peer-reviewed)abstract
- The aim of the study was to describe the patients' experiences of the information and support they received after being placed on the waiting list for a heart or lung transplant. The design was qualitative, and the critical incident technique was used. Incidents were collected via interviews with 21 patients. A total of 357 important events, both positive and negative, were identified and divided into two main groups: Body and mind and Information and support. The following subgroups emerged: chronic illness affects the patients, attitudes towards the future, impact of information, support from public organizations, and support from the private sphere. The patients showed knowledge of and involvement in the upcoming transplantation, which indicates that healthcare professionals managed to convey information and support effectively. By identifying the importance of factors such as body and mind and information and support for patients recently accepted for heart or lung transplantation, healthcare professionals are able to make specific improvements in the information and support that they provide. An important implication is to enhance the knowledge regarding transplant patients in other institutions and improve cooperation. Specific support programs to assist patients who have dependent children should be developed. Society needs to become more enlightened about organ donation and transplantation patients.

No detrimental effect on renal function during long-term use of fluvastatin in renal transplant recipients in the Assessment of Lescol in Renal Transplantation (ALERT) study
- 2006
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 20:6, s. 732-739
-
Journal article (peer-reviewed)abstract
- Background: Concerns have recently been raised regarding a potential harmful effect of statins on renal function. This study investigated the effect of fluvastatin treatment on renal function in renal transplant recipients enrolled in the Assessment of Lescol in Renal Transplantation (ALERT) trial. Methods: ALERT was a randomized, double-blind, placebo-controlled study of the effect of fluvastatin, 40-80 mg daily (n = 1050) or placebo (n = 1052) on cardiac and renal outcomes in renal transplant recipients over a follow-up period of five to six years. The incidence of graft loss, changes in serum creatinine, calculated creatinine clearance and proteinuria, and the incidence of renal adverse events (AEs) were assessed in both treatment groups. Results: Fluvastatin treatment in ALERT had no significant effect compared with placebo on renal function, assessed by serum creatinine (overall adjusted mean +/- SEM: fluvastatin, 175.4 +/- 2.20 mu mol/L; placebo, 172.7 +/- 2.20 mu mol/L; p = 0.39), creatinine clearance (fluvastatin, 55.3 +/- 0.30 mL/min; placebo, 55.8 +/- 0.30 mL/min; p = 0.26) or proteinuria (fluvastatin, 0.58 +/- 0.03 g/24 h; placebo, 0.53 +/- 0.03 g/24 h; p = 0.31). There were no significant differences between treatment groups when the 283 patients suffering graft loss were excluded from the analysis. Fluvastatin also had no detrimental effect on creatinine clearance or proteinuria in the subgroup of 340 diabetic patients without graft loss in ALERT. No notable differences in the rate of renal or musculoskeletal AEs were observed between fluvastatin and placebo groups. Conclusions: Fluvastatin had no detrimental effect on renal function, or the risk of renal AEs, in renal transplant recipients with or without diabetes enrolled in ALERT. Fluvastatin treatment for the prevention of cardiac events may therefore be used without fear of jeopardizing renal function.

Religious beliefs and opinions on clinical xenotransplantation : a survey of university students from Kenya, Sweden and Texas
- 2001
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 15:6, s. 421-425
-
Journal article (peer-reviewed)abstract
- This study investigated the association between religious beliefs and opinions on xenotransplantation among students from three different countries. A lower proportion of religious students accepted xenotransplantation than did non-religious students. A higher proportion of Protestant students seemed to accept xenotransplantation than did Muslim and Roman Catholic students. A higher proportion of the religious respondents had not formed an opinion on xenotransplantation compared to non-religious students. There was no difference according to gender on views on xenotransplantation, but a higher proportion of older students seemed to accept xenotransplantation than did younger students. A higher proportion of non-vegetarians reported acceptance of xenotransplantation than did vegetarians. Acceptance of xenotransplantation was higher in Sweden compared to the two other regions, and the proportion of students who had formed an opinion was higher as well.

Students' acceptance of clinical xenotransplantation
- 2000
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 14:3, s. 252-256
-
Journal article (peer-reviewed)abstract
- The aim of this study was to elucidate undergraduate university students' views on clinical xenotransplantation. A total of 1875 students From eight faculties at Uppsala University and the Swedish University of Agricultural Sciences answered a questionnaire. Three out of four respondents would be prepared to receive a transplant from an animal on medical grounds if necessary. Forty percent had signed an organ donation card. There was no difference in attitude between those who had signed an allotransplantation card and those who had not. According to gender, age, length of university program, and faculty, results showed that a higher proportion of those who approved were male, young, and studying on programs longer than three years; also, they were more likely to study programs in the Faculties of Agriculture and Pharmacy. At the Medical Faculty, nursing studentsseemed to be less approving, compared to future biomedical analysts, biomedical scientists, and physicians. The acceptance of xenotransplantation also tended to be positively associated with morally accepting and understanding the use of animals in biomedical research, the approval of euthanasia, the approval of early abortion, and the use of human fetuses in research, as well as clinical testing of humans.

Remaining experiences of living kidney donors more than 3 yr after early recipient graft loss
- 2003
-
In: Clinical Transplantation. - : John Wiley & Sons. - 0902-0063 .- 1399-0012. ; 17:6, s. 503-510
-
Journal article (peer-reviewed)abstract
- Living kidney donor programs, based on willingness among family members and close relatives to donate, have made it possible to perform a satisfactory number of kidney transplantations. Early graft loss in the recipient may occur and it is not known if such an event will result mainly in acute, rather transient, emotional reactions or if long-lasting reactions may be evoked in the living kidney donor. The aim of the present study was to assess and describe the remaining experiences of donors (n = 10) more than 3 yr after early recipient graft loss or death of the recipient. A phenomenographic, interview-based research approach was used. Five different fields or domains were identified: (i) the decision to donate; (ii) the information provided; (iii) care received at the time of donation; (iv) responses at graft failure; and (v) concerns remaining at the time of the interview. All donors expressed that they had volunteered to donate and that no stress had been put on them. The information given prior to and in connection with the donation procedure was deemed insufficient but all donors were satisfied with the medical care provided in connection with the nephrectomy and in the immediate post-operative period. Graft failure was immediately accepted on the intellectual level by nine of 10 donors but still evoked emotional reactions and responses included a wish that continuing contact with the transplant staff had been provided. The present interview-based study shows that it is of importance that the donor is thoroughly informed about all donor as well as recipient-related factors including the potential risk of recipient graft failure. In case of graft failure, or the death of the recipient, the transplant unit staff members should offer contact for discussions of medical matters as well as for psychosocial support. In individual cases it may be necessary to maintain such a supportive contact channel for a prolonged period of time.

Tacrolimus combined with two different corticosteroid-free regimens compared with a standard triple regimen in renal transplantation : one year observational results
- 2010
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 24:1, s. E1-E9
-
Journal article (peer-reviewed)abstract
- Side effects of steroid use have led to efforts to minimize their use in transplantation. Two corticosteroid-free regimens were compared with a triple immunosuppressive therapy. Data from the original intent-to-treat (ITT) population (153 tacrolimus/basiliximab [Tac/Bas], 151 tacrolimus/MMF [Tac/MMF], and 147 tacrolimus/MMF/steroids [control]) were analyzed in a 12-month follow-up. Percentage of graft survival were 92.8%, 95.4%, and 95.9% (KM estimates 89.9%, 95.3%, 95.9%), percentage of surviving patients were 98.7%, 98.0%, and 100% (KM estimates 95.9%, 92.8%, and 100%). During months 7-12, graft loss occurred in 3 Tac/Bas, 2 Tac/MMF, and zero control patients, patient deaths in 1 Tac/Bas, 2 Tac/MMF, and zero control, and biopsy-proven acute rejection episodes in 4 Tac/Bas, 3 Tac/MMF, and zero control. Mean serum creatinine at month 12 was 141.9 +/- 69.6 muM, 144.0 +/- 82.1 muM, and 134.5 +/- 71.2 muM (ns). New-onset insulin use in previously non-diabetic patients at month 12 was 1/138, 6/127, and 4/126. Patient and graft survival as well as renal function at 12 months were not different between patient groups, despite considerably higher rates of acute rejection occurring within the first six months after transplantation in both steroid-free patient groups. Tac/Bas therapy might offer benefits in terms of a trend for a more favorable cardiovascular risk profile.

Macrovascular disease after simultaneous pancreas and kidney transplantation.
- 2004
-
In: Clinical transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 18:4, s. 372-6
-
Journal article (peer-reviewed)abstract
- The objective of this study was to evaluate the outcome of simultaneous pancreas and kidney transplantation (SPK) with focus on cardiovascular mortality and morbidity in relation to graft function. From January 1985 through 1999, 87 SPK were performed in the unit. Sixty recipients were males, median age at diabetes onset 13 yr (1-40) and age at transplantation 39 yr (29-54). No case was lost to follow-up. Morbidity and mortality during median 8 yr of follow-up (range 1-15 yr) were recorded. Major macrovascular disease (MVD) was defined as myocardial infarction or sudden death (AMI), stroke or peripheral gangrene requiring amputation of leg, foot or fingers. At the evaluation, 26 of 87 patients (30%) had died, 19 after loss of the pancreas graft and 20 after loss of the kidney. MVD was the dominant cause of death. Non-lethal MVD had previously been recorded in 62%. Of the 61 patients alive, 22 had lost their pancreas graft and 12 the concomitant kidney. MVD had occurred in 32%. Whereas 89% of the concomitant kidneys functioned when the pancreas graft did so, only 37% of the kidneys functioned if the pancreas had been lost, p < 0.0001. The mortality rate was significantly higher among patients who lost both grafts (16/26) than in those who lost only the pancreas graft (3/15), p = 0.01. Progressive MVD is a major clinical problem for SPK transplant patients, particularly if the kidney fails.

Gender-associated risk factors for cardiac end points and total mortality after renal transplantation : post hoc analysis of the ALERT study
- 2006
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 20:3, s. 374-82
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Female gender offers a cardioprotective effect over men in the general population, but is lost in the dialysis population. Whether renal transplantation restores the gender-dependent cardiac protection and whether there is a difference in the impact of risk factors is not known. METHODS: This is a post hoc analysis of pre-defined end points in the placebo arm in the Assessment of Lescol in Renal Transplantation (ALERT) study, a study in renal transplant recipients. Cox regression was performed to estimate the association between different risk factors at baseline and non-fatal myocardial infarction (MI) or cardiac death and total mortality, and specifically assess whether there are gender differences. RESULTS: The placebo arm included 1052 patients (mean age 50.1 +/- 11.1 yr, 65.3% males) with a mean follow-up of 65 months. The incidence of non-fatal MI or cardiac death was 10.9% vs. 7.9% (NS) and total mortality 13.3% vs. 12.8% (NS) in men and women. In multivariate analysis, previous coronary heart disease (CHD), diabetes, treatment for rejection and serum triglycerides were predictive for cardiac events in men, and low-density lipoprotein (LDL)/high-density lipoprotein (HDL) ratio only in women. A slightly different risk-factor pattern appeared for total mortality. Diabetes, ECG abnormalities, plasma triglycerides, serum creatinine, time on dialysis and age predicted total mortality in men, while ECG abnormalities, LDL/HDL ratio and age were predictors in women. CONCLUSION: In this relatively low-risk population of renal transplant recipients, no gender difference in cardiac events or total mortality was observed, suggesting that female gender advantage regarding CHD is not restored following transplantation. The predictive value of risk factors differed in men and women.

Second allogeneic hematopoietic stem cell transplantation : a treatment for graft failure
- 2011
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 25:1, s. E68-E76
-
Journal article (peer-reviewed)abstract
- We evaluated the results in 20 recent patients treated with a second hematopoietic stem cell transplantation (HSCT) after graft failure (GF). There were 10 children <18 yr of age. Ten patients had a non-malignant disease, and the other 10 had a malignant disease. In most of the transplantations, fludarabine-based reduced intensity conditioning (RIC) was given. Bone marrow was given to 11 patients, peripheral blood system cell (PBSC) in seven and cord blood to two patients. For the second transplantation (n = 20), a new donor was used in nine cases, while the initial donor was used in 11 transplants. Eight patients (40%) suffered from a second GF. Five of these patients were treated with a third HSCT. The probability of survival was 65% one yr and 60% three yr after the second HSCT. No difference in survival was found between patients transplanted with a new donor (56%) compared to those using the original donor (64%). The three-yr survival was 70% for children compared to 50% for adults (p = ns). Patients with a non-malignant disorder showed a three-yr survival of 90% compared to 20% in patients with a malignant disease (p = 0.005). We concluded that re-transplantation using RIC is a valid option for GF, especially in patients with non-malignant disorders.

Transplant recipients' conceptions of three key phenomena intransplantation : the organ donation, the organ donor and the organ transplant.
- 2003
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 17:4, s. 391-400
-
Journal article (peer-reviewed)abstract
- Thirty-five heart and kidney transplant patients were interviewed on five separate occasions during the first 2 yr after transplantation. The aim was to explore their experiences of phenomena that distinguish the transplantation from other kinds of medical treatment. The selection of informants was designed to permit comparisons between recipients with heart and kidney transplants and with living and necro-transplants. The qualitative analysis of the informants' reactions was focused on three themes; nine categories emerged. The first theme concerned general aspects of the donation and the donor and was differentiated in four categories: joy and sorrow, gratefulness and indebtedness, guilt, and inequity. The second theme related to the donor as a unique individual and included three categories: recognition and identification with the donor, influences of the donor, and relationship to the living donor. The third theme pertained to incorporation of the transplant and included two categories related to the naturalness of having a transplant, and the benevolent transplant. The informants' reactions were discussed in terms of primary and secondary processes. All informants were in an emotionally charged situation after transplantation and warded off anxiety-provoking impulses, most intensively during the first 6 months. Avoidance, suppression, and denial were the most common defence mechanisms, all of which seemed to be supported by the medical context. Other, more constructive strategies are suggested. The recipients' own interpretations of causes to possible personality changes are discussed. There were few differences between heart and necro-kidney patients concerning the reactions to the donation, the donor, and the transplant; the dividing line was more prominent between recipients with living and necro-transplants.

People's feelings and ideas about receiving transplants of different origins : questions of life and death, identity, and nature's border
- 2001
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 15:1, s. 19-27
-
Journal article (peer-reviewed)abstract
- The aim of this study was to explore the public's feelings and ideas with regard to receiving transplants of different origins. Sixty-nine individuals with varying sociodemographic background, selected from samples who had responded to a questionnaire on receiving and donating organs, were interviewed in-depth. A wide variety of reactions was displayed. The feelings and ideas about receiving organs were summarized in ten categories: 1) the emergency situation; 2) the functioning of the transplant; 3) the influence of transplants on personality, behaviour, and appearance; 4) the influence of transplants on body image; 5) disgust; 6) cannibalism; 7) trespassing nature's border; 8) tradition; 9) ethical considerations; and 10) the debt of gratitude. Most individuals were willing to accept at least one organ. Animal organs were the least preferred. The hierarchy of organ preferences – with organs from a relative at the top and animal organs at the bottom – was explained in terms of rational, magical, and analogy thinking. Finally, the consequences for the encounter between health care personnel and transplantation candidates were briefly discussed.

Increased arterial stiffness in cyclosporine-treated lung transplant recipients early after transplantation
- 2004
-
In: Clin Transplant. - : Wiley. - 0902-0063. ; 18:4, s. 473-9
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The majority of patients undergoing solid organ transplantation develop hypertension, to which cyclosporine (CsA)-induced peripheral vasoconstriction may contribute. We hypothesized that CsA-treated transplant recipients have an increased basal vascular tone and an altered response to nitric oxide. To test this hypothesis arterial resistance, non-endothelial dependent relaxation and arterial stiffness were investigated in CsA-treated lung transplant recipients within 18 months after transplantation. METHODS: In study 1, forearm blood flow (FBF) was measured by venous occlusion plethysmography at baseline and during glyceryl trinitrate (GTN) and N(G)-monomethyl-l-arginine acetate (l-NMMA) infusion in seven lung transplant recipients and nine healthy subjects. In study 2, arterial stiffness in carotid (CCA) and radial artery (RA) was measured by ultrasound (echo-tracking) in 10 lung transplant recipients, 12 healthy subjects and six patients waiting for lung transplantation. RESULTS: Basal FBF (3.1 +/- 0.2 vs. 3.0 +/- 0.3 mL/min, p = 0.79) and forearm arterial resistance (36 +/- 3 vs. 33 +/- 3 mmHg/mL/min, p = 0.60) did not differ between transplant recipients and controls. GTN infusion increased and l-NMMA decreased blood flow equally in both groups. Transplant recipients had increased arterial stiffness compared to both pre-transplant patients and healthy subjects (CCA stiffness index 11.7 +/- 1.1 vs. 8.5 +/- 0.2 and 8.6 +/- 0.6, p < 0.05 both; RA stiffness index 14.7 +/- 1.5 vs. 8.9 +/- 1.3 and 10.6 +/- 0.7, p < 0.05 both). CONCLUSIONS: Forearm blood flow and arterial resistance did not differ between healthy subjects and cyclosporine-treated lung transplant recipients early after transplantation. Increased arterial stiffness was demonstrated in transplant recipients, which may have implications for future development of transplant hypertension.

Metabolic syndrome and cardiovascular risk in renal transplant recipients : effects of statin treatment
- 2009
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 23:6, s. 914-920
-
Journal article (peer-reviewed)abstract
- Background: Renal transplant recipients (RTR) have high risk for cardiovascular disease (CVD). They also have high prevalence of insulin resistance and metabolic syndrome (MS). Statin treatment reduces CVD risk in RTR. The aim was to study MS as CVD risk factor in RTR, and to investigate the effect of statin treatment in RTR with MS. Methods: In total, 1706 non-diabetic RTR from the Assessment of Lescol in Renal Transplantation trial were followed for 7-8 yr. The captured endpoints included major adverse cardiac events [MACE, defined as cardiac death (CD), non-fatal myocardial infarction or coronary revascularization procedure], and CD. MS was defined at baseline according to Adult Treatment Panel III definition with waist girth replaced by body mass index >/=30 kg/m(2). Results: MS was diagnosed in 32% of the patients. During the follow-up, MACE incidence was 16% in those with MS and 11% in those without MS (p < 0.001). Statin treatment reduced MACE risk by 53% in the group with MS. CD risk was 74% higher in RTR with MS (p = 0.012), and statin treatment reduced CD risk in those with MS (p = 0.03). Conclusions: RTR with MS have increased risk for CVD. RTR with MS are an easily identifiable group of patients who benefit from statin treatment.

Journal article (peer-reviewed)abstract
- Background: Cytomegalovirus (CMV) infection is still the leading opportunistic infection following solid organ transplantation. The aim of this prospective study of renal transplant recipients was to evaluate the dynamics of CMV-specific T-cells, viral load, and clinical symptoms of CMV infection.Methods: Levels of tetramer-selected CD8+ T-cells (TetraCD8), CMV-specific interferon-γ producing CD8+ T-cells (IFNγCD8), and CD4+ T-cells (IFNγCD4), measured using major histocompatibility complex-tetramer and cytokine flow cytometry techniques, and CMV DNA were monitored monthly in 17 CMV-seropositive patients up to one yr (median 12 months, range 3–12) after transplantation and correlated to clinical outcome.Results: CMV DNAemia was detected in 94% of the patients, but only one patient developed CMV disease. CMV DNAemia >1 million copies/mL was seen in asymptomatic patients. CMV-specific T-cells decreased rapidly after transplantation. TetraCD8 and IFNγCD8 regenerated within three months, whereas IFNγCD4 recovery was impaired up to one yr after transplantation. The proportion of IFNγCD4 at two months post-transplantation as compared with baseline, correlated strongly with the magnitude of the CMV DNAemia.Conclusions: Monitoring the reduction of IFNγCD4 compared with baseline during the first months after transplantation could be considered in predicting risk for high-grade CMV DNAemia and in deciding strategic approaches for pre-emptive and prophylactic therapy.

Cholesterol lowering with EVOLocumab to prevent cardiac allograft Vasculopathy in De-novo heart transplant recipients : Design of the randomized controlled EVOLVD trial
- 2020
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 34:9
-
Journal article (peer-reviewed)abstract
- Background: Cardiac allograft vasculopathy (CAV) is characterized by diffuse thickening of the arterial intima. Statins reduce the incidence of CAV, but despite the use of statins, CAV remains one of the leading causes of long-term death after heart transplant. Inhibitors of proprotein convertase subtilisin-kexin type 9 (PCSK9) substantially reduce cholesterol levels but have not been tested in heart transplant recipients. Methods: The Cholesterol lowering with EVOLocumab to prevent cardiac allograft Vasculopathy in De-novo heart transplant recipients (EVOLVD) trial (ClinicalTrials.gov Identifier: NCT03734211) is a randomized, double-blind trial designed to test the effect of the PCSK9 inhibitor evolocumab on coronary intima thickness in heart transplant recipients. Adults who have received a cardiac transplant within the past 4-8 weeks are eligible. Exclusion criteria include an estimated glomerular filtration rate < 20 mL/min/1.73 m2, renal replacement therapy, or contraindications to coronary angiography with intravascular ultrasound. 130 patients will be randomized (1:1) to 12-month treatment with evolocumab or matching placebo. The primary endpoint is the coronary artery intima thickness as measured by intravascular ultrasound. Conclusion: The EVOLVD trial is a randomized clinical trial designed to show whether treatment with the PCSK9 inhibitor evolocumab can ameliorate CAV over the first year after heart transplant.

Uric acid and clinical correlates of endothelial function in kidney transplant recipients
- 2014
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 28:10, s. 1167-1176
-
Journal article (peer-reviewed)abstract
- Uric acid is associated with increased mortality in kidney transplant recipients (KTRs), but it is uncertain if this involves endothelial dysfunction. We hypothesized, first, that there was an association between uric acid and endothelial function, and second, that there were associations between endothelial function and cardiac and mortality risk scores.METHODS: One hundred and fifty-two patients were examined 10 wk after kidney transplantation by two measures of endothelial function, the brachial artery flow-mediated dilatation (FMD) expressed as percent dilatation (FMD%), and fingertip peripheral arterial tone (PAT) expressed as log-reactive hyperemia index (LnRHI). Risk scores were calculated from a recently validated formula. Other clinical correlates of endothelial function were described in stepwise linear regression models.RESULTS: Uric acid was associated negatively with FMD% in an age- and gender-adjusted model, while not in the multivariable model. No association was shown between uric acid and LnRHI. FMD% was associated negatively with risk scores in both crude and age- and gender-adjusted models (p < 0.01). LnRHI was associated negatively with risk scores in the latter model only (p < 0.05).CONCLUSIONS: Uric acid was neither associated with FMD% nor LnRHI in KTRs. There were significant associations between endothelial function indices and cardiac and mortality risk scores.

Journal article (peer-reviewed)abstract
- Eighty-five renal transplant recipients were prospectively monitored for CMV infection up to 4 months post-transplantation by virus isolation from leukocytes, CMV antigen detection (pp65) in peripheral blood leukocytes (PBL), polymerase chain reaction (PCR) of alkaline treated plasma (P-PCR), PCR of extracted DNA from PBL (L-PCR) and serology. Additionally univariate and multivariate analyses of risk factors for patient and graft survival up to 4 yr post-transplantation were performed. The incidence of CMV infection was 78% and of CMV disease 33%. Antigen detection in PBL was positive before or at onset of symptoms in 23/24 (96%) evaluable patients with CMV disease. The corresponding figures for virus isolation were 22/24 (92%), P-PCR 21/24 (88%) and for L-PCR 18/24 (75%). The percentage of negative samples in patients without CMV disease was 89% for the antigen test, 92% for L-PCR and 83% for virus isolation and P-PCR. One rapid test (antigen test, P-PCR or L-PCR) was positive at a median of 16 d before the onset of symptoms. The antigen test was generally the first rapid test to become positive. CMV disease did not affect graft survival in the multivariate analysis but was associated with decreased patient survival.

Validation of cause of death classification after heart transplantation and cause-specific life expectancy compared to the general population
- 2022
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 36:9
-
Journal article (peer-reviewed)abstract
- Background: Post heart-transplant survival has increased, but information is lacking on specific causes of death and life expectancy. We aimed to assess cause-specific loss of life-years compared to the general population, evaluate classification for cause of death after heart transplantation, and assess validity of cause of death data from the International Society of Heart and Lung Transplant (ISHLT) registry. Methods: In this single center study, we included 239 heart recipients transplanted between 1988 and 2019 in Lund, Sweden (n = 239, 50% of the transplanted population where the cause of death was available). Two cardiologists retrospectively assigned causes of death according to a published classification (CLASS) in the 91 recipients who died during follow-up. Life expectancy was compared to data from the general population. Results: Compared to the average Swedish population, life expectancy for heart transplant recipients was 20 years shorter (IQR 12.9–27.2). The largest number of life-years lost were for deaths due to acute (49 years) and chronic rejection (27 years). Primary graft dysfunction (24 years) accounted for 24% of deaths, followed by malignancy (20 years) and infection (17 years), each accounting for ∼20% of deaths. Use of CLASS revealed moderate inter-rater agreement (56%) and moderate agreement with the ISHLT registry (62%). Conclusions: Survival after heart transplantation was 20 years lower than in the general population. In the young, more life-years were lost due to acute graft rejection, whereas chronic graft rejection and primary graft failure were more important causes of death in older patients. Agreement was moderate between CLASS and the ISHLT registry classifications.

Bone and hormonal status 10 years post-allogeneic bone marrow transplantation
- 2019

In: Clinical Transplantation. - : WILEY. - 0902-0063 .- 1399-0012. ; 33:12
-
Journal article (peer-reviewed)abstract
- Bone loss and endocrine dysfunction are potential late complications of allogeneic stem cell transplant (allo-SCT); however, scant information concerning the long-term effects in SCT adult patients is available. In the present study, we evaluated bone status, expressed as bone mineral density (BMD), and endocrine functions including PTH, TSH, free T4, testosterone, SHBG, FSH, LH, and IGF-1, in 20 adult leukemia patients >10 years after allo-SCT. A low BMD (Z score <-2.0) was observed in two patients; two patients had osteoporotic fractures, and two had a unilateral avascular necrosis of the femoral head. Elevated PTH was observed in 30% of patients, and 25-hydroxy vitamin D (25(OH)D) was low (<50 nmol/L) in 45% of the patients. The majority of the patients had thyroid tests within the reference range, while elevated FSH values were present in 8 of 12 males. We conclude that adult leukemia patients have relatively well-preserved BMD >10 years post-allo-SCT. Prophylactic treatment of osteoporosis should be individualized, but control of BMD is necessary for long-term follow-up. Control of PTH and vitamin D levels before and after allo-SCT is recommended, and vitamin D supplementation should be considered if indicated. Estrogen replacement therapy is a routine treatment in females, whereas gonadal function in males requires further investigation.

Journal article (peer-reviewed)abstract
- Primary graft dysfunction (PGD) is a leading cause of 30- day mortality following heart transplantation, and early intervention in PGD may correlate to improved survival. Our analysis aimed to determine the feasibility of measuring cardiac biomarkers from the donor heart in the early phase for use as a predictor of PGD.Blood samples from the coronary sinus were obtained at the time of transplantation in hearts preserved by cold static storage. The samples were analyzed for CK-MB and cTnI with a point-of-care method. The primary outcome was severe PGD or the need for veno-arterial extracorporeal membrane oxygenation within 7 days, referred to as severe graft dysfunction.Of the total cohort (n = 63), eight patients (13%) were diagnosed with severe graft dysfunction within 7 days. Patients with high CK-MB had an increased risk for severe graft dysfunction with unadjusted Odds Ratio (OR) of 4.5 (95%CI 0.96-21.11 p = 0.057) and adjusted OR of 7.4 (95%CI 1.13-48.46, p = 0.037. Similar but non Clinical Transplantation For Review Only significant trends were observed for cTnI.By measuring CK-MB from the coronary effluent in the donor heart, it may be possible to identify patients at increased risk for severe PGD after heart transplantation.

The influence of ischemia and reperfusion time on outcome in heart transplantation
- 2020

Journal article (peer-reviewed)abstract
- Ischemia/reperfusion may lead to graft dysfunction in heart transplantation (HT). The purpose of this study was to evaluate the influence of ischemic and reperfusion time on acute cellular rejection (ACR) within the first-year post-HT and on long-term outcomes. Data were collected from 331 patients (mean age 49 ± 12 y, 28% females) who underwent HT 1988-2016. Endomyocardial biopsies obtained within the first year after HT were graded according to the 2004-ISHLT-WF. We classified the patients by ischemic time 4 hours, and of these, 31 (55%) patients had reperfusion with CPB ≥90 minutes. Ischemia >4 hours had an increased risk of ACR ≥ 2R during the first year (adjusted OR = 3.1, P =.016); however, an extended reperfusion ≥90 minutes reduced the risk (adjusted OR = 0.25, P =.024). The conditional probability of surviving 10 years post-transplant, given that the patients already survived first year, was inferior for recipients with ischemia ≥ 4 hours and reperfusion <90 minutes, 59%, compared with the other groups 83%, P =.016. Prolonged reperfusion appears to reduce the risk for ACR ≥ 2R and improve long-term survival.

Bone mineral density and osteoporosis in heart transplanted patients : A single-center retrospective study at Skåne University Hospital in Lund 1988-2016
- 2019
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 33:3

Journal article (peer-reviewed)abstract
- Bone mineral density (BMD) in the lumbar spine and femoral neck, the incidence of osteoporosis, and survival up to 10 years after heart transplantation (HT) were investigated in 169 patients who underwent HT at Skåne University Hospital in Lund, Sweden, 1988-2016. Within the first year post-transplantation, mean (SD) BMD decreased by 3.9% (10.1) (P < 0.001) and 9.0% (10.5) (P < 0.001) in the lumbar spine and femoral neck, respectively. The cumulative incidence of osteoporosis in the lumbar spine and femoral neck increased rapidly within the first year after HT and was detected in 17% and 13% of the patients, respectively. A higher T score before HT was a negative predictor of osteoporosis up to 10 years post-HT in the lumbar spine (HR 0.13; 95% CI 0.063-0.26; P < 0.001) and femoral neck (HR 0.54; 95% CI 0.34-0.85; P < 0.001). Moreover, only 13%, 14%, and 6% of the HT patients received calcium, vitamin D, and/or bisphosphonates before HT. In conclusion, BMD drops significantly during the first postoperative year. Optimization of BMD early among HT candidates, potentially through usage of osteoporosis preventive treatment, may be a future means to prevent osteoporosis late postoperatively.

Clinical relevance of endoscopy with histopathological assessment in children with suspected gastrointestinal graft-versus-host disease
- 2020
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 34:7
-
Journal article (peer-reviewed)abstract
- Endoscopy with histopathological assessment is an established practice to confirm gastrointestinal graft-versus-host disease (GI-GVHD). However, the clinical relevance of this approach in children is incompletely evaluated. In a retrospective cohort study, we investigated the frequency of treatment changes in response to histopathological findings in all children (<18 years) in Sweden who underwent endoscopy for suspected GI-GVHD (2000-2013) after receiving hematopoietic stem cell transplantation. Sixty-eight children with ninety-one endoscopic occasions were enrolled. At the time of endoscopy, anti-GI-GVHD treatment was ongoing in 71% (65/91). In 18% (12/65) with ongoing treatment, no histopathological evidence of GI-GVHD or another cause to justify anti-GI-GVHD treatment was found. In 48% (44/91), endoscopy with histopathological assessment led to changes in the treatment regimen. Re-endoscopy was more frequent among those with treatment changes, versus unchanged treatment, 39% (17/44) and 13% (6/47), respectively (P = .007). Histopathological findings generating treatment changes were as follows: GI-GVHD in 68% (30/44), normal histology in 25% (11/44), and an alternative diagnosis in 7% (3/44). In conclusion, this study supports that endoscopy with histopathological assessment should be considered in all children with suspected GI-GVHD.

Glomerular macrophage index (GMI) in kidney transplant biopsies is associated with graft outcome
- 2022
-
In: Clinical Transplantation. - : John Wiley & Sons. - 0902-0063 .- 1399-0012. ; 36:12
-
Journal article (peer-reviewed)abstract
- Background: Macrophages in renal transplants have been shown to participate in antibody-mediated rejection and are associated with impaired renal function. We calculated the glomerular macrophage index (GMI) in a large transplant biopsy cohort, studied its quantity in different diagnostic groups, to clarify its possible impact on graft survival.Methods: GMI, defined as the mean number of macrophages in 10 glomeruli, was prospectively quantified in 1440 renal transplant biopsies over a 10-year period. The main histopathological diagnoses were grouped into eight disease entities, and GMI was compared to normal transplant biopsies as the reference group. The impact of GMI on graft survival was analyzed.Results: GMI was highest in chronic (mean 9.4) and active (9.7) antibody mediated rejections (ABMR), mixed rejections (7.6), and recurrent or de novo glomerulonephritis (7.5) and differed significantly from normal transplants (1.3) in almost all diagnostic groups. Hazard ratios for graft loss were significantly increased for all biopsies with GMI ≥1.9 compared to GMI <.5 (reference group) in an adjusted Cox regression model and increased with higher GMI levels. Biopsies with GMI ≥ 4.6 had < 60% 10-year graft-survival, compared to > 80% with GMI ≤ 1.8.Conclusion: GMI levels were predictive of graft loss independent of histological diagnoses and may guide clinicians to decide follow-up and therapy.

Changes in numbers of glomerular macrophages between two consecutive biopsies and the association with renal transplant graft survival
- 2024
-
In: Clinical Transplantation. - : John Wiley & Sons. - 0902-0063 .- 1399-0012. ; 38:7
-
Journal article (peer-reviewed)abstract
- Background: Macrophages are involved in kidney transplants. The aim of the study was to investigate if changes exist in the levels of glomerular macrophage index (GMI) between two consecutive kidney transplant biopsies, and if so to determine their potential impact on graft survival.Methods: Two consecutive biopsies were performed on the same renal graft in 623 patients. GMI was categorized into three GMI classes: ≤1.8 Low, 1.9–4.5 Medium, and ≥4.6 High. This division yielded nine possible switches between the first and second biopsies (Low-Low, Low-Medium, etc.). Cox-regressions were used and hazard ratios (HR) with 95% confidence interval (CI) are presented.Results: The worst graft survival was observed in the High-High group, and the best graft survival was observed in the Low-Low and High-Low groups. Compared to the High-High group, a reduction of risk was observed in nearly all other decreasing groups (reductions between 65% and 80% of graft loss). After adjustment for covariates, the risk for graft-loss was lower in the Low-Low (HR = 0.24, CI 0.13–0.46), Low-Medium (HR = 0.25, CI 0.11–0.55), Medium-Low (HR = 0.29, CI 0.11–0.77), and the High-Low GMI (HR = 0.31, CI 0.10–0.98) groups compared to the High-High group as the reference.Conclusions: GMI may change dynamically, and the latest finding is of most prognostic importance. GMI should be considered in all evaluations of biopsy findings since high or increasing GMI levels are associated with shorter graft survival. Future studies need to consider therapeutic strategies to lower or maintain a low GMI. A high GMI besides a vague histological finding should be considered as a warning sign requiring more frequent clinical follow up.

Induction immunosuppression strategies and long-term outcomes after heart transplantation
- 2020
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 34:7
-
Journal article (peer-reviewed)abstract
- Although the use of induction therapy has reduced the risk of acute rejection after heart transplantation, its use may be associated with other adverse outcomes. We aimed to examine the effect of no induction (NoInd), induction with basiliximab (BAS), or induction with antithymocyte globulin (ATG) on outcome after heart transplantation. We analyzed data from the International Society for Heart and Lung Transplantation (ISHLT) registry for adult heart transplants performed between 2000 and 2013. The primary outcome was cumulative all-cause mortality, and the secondary outcome was cause-specific death. We identified 27 369 transplants whose recipients received NoInd (n = 15 688), ATG (n = 6830), or BAS (n = 4851). Over a median follow-up of 1497 days, overall 30-day mortality was 5% and 1-year mortality was 11%. Survival after transplant was similar in patients treated with NoInd compared with ATG. The survival was improved using NoInd compared with BAS (log-rank P =.040), adjustment HR = 1.11 (95% CI, 1.04-1.19). Compared to NoInd, BAS was associated with higher risk of graft failure-related deaths, HR = 1.27 (95% CI, 1.02-1.58), and ATG was associated with higher risk of malignancy-related deaths, HR = 1.18 (95% CI, 1.01-1.39). Survival of patients who received NoInd was similar to ATG and better compared with BAS. Further, the use of ATG may be associated with increased malignancy-related mortality, compared with NoInd.

Neopterin is associated with cardiovascular events and all-cause mortality in renal transplant patients
- 2014
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 28:1, s. 111-119
-
Journal article (peer-reviewed)abstract
- BackgroundInflammatory markers show significant associations with cardiovascular events and all-cause mortality after kidney transplantation. Neopterin, reflecting interferon--release, may better reflect the proinflammatory state of recipients than less specific markers. MethodsKidney transplant recipients in the Assessment of LEscol in Renal Transplant (ALERT) trial were examined and investigated for an association between serum neopterin and subsequent clinical events: graft loss, major cardiovascular events (MACE) and all-cause mortality. ResultsAfter adjustment for established and emerging risk factors neopterin expressed as neopterin-to-creatinine ratio was significantly associated with MACE (p=0.009) and all-cause mortality (p=0.002). Endpoints were more frequent with increasing quartiles of neopterin-to-creatinine ratio. The incidence rates of MACE and all-cause mortality were significantly increased in the upper quartiles compared with the first. ConclusionsThis long-term prospective analysis in stable kidney allograft recipients suggests that neopterin is associated with long-term risk of cardiovascular events and all-cause mortality, but not renal outcomes.

Effect of everolimus vs calcineurin inhibitors on quality of life in heart transplant recipients during a 3-year follow-up : Results of a randomized controlled trial (SCHEDULE)
- 2017
-
In: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 31:9
-
Journal article (peer-reviewed)abstract
- The Scandinavian heart transplant everolimus de novo study with early calcineurin inhibitors avoidance (SCHEDULE) trial was a 12 month, randomized, open-label, parallel-group trial that compared everolimus (EVR; n=56) to conventional CsA (n=59) immunosuppression. Previously, we reported that EVR outperformed CsA in improving renal function and coronary artery vasculopathy, despite a higher rejection rate with EVR. This study aimed to compare the effects of these treatments on quality of life (QoL). Within five post-operative days, patients (mean age 50±13 years, 27% women) were randomized to EVR or a standard CsA dosage (CsA group). This study assessed quality of life (QoL), based on the Short Form-36, EuroQol-5D, and Beck Depression Inventory (BDI). Assessments were performed pre-HTx and 12 and 36 months post-HTx. At 12 and 36 months, the groups showed similar improvements in Short Form-36 measures (at pre-HTx, 12 and 36 months the values were as follows: Physical component summary: EVR: 31.5±110.9, 49.1±9.7, and 47.9±10.6; P<.01; CsA: 32.5±8.2, 48.4±8.5, and 46.5±11.5; P<.01; mental component summary: EVR: 46.0±12.0, 51.7±11.9, and 52.1±13.0; P<.01; CsA: 38.2±12.5, 53.4±7.1, and 54.3±13.0; P<.01); similar decrease in mean BDI (EVR: 10.9±10.2, 5.4±4.7, and 8.1±9.0; P<.01; CsA: 11.8±7.1, 6.3±5.4, and 6.2±6.5; P<.01); and similar Euro Qol-improvements. Thus, in this small-sized study, EVR-based and conventional CsA immunosuppressive strategies produced similar QoL improvements.

Evaluation of an organ-donor-card-campaign in Sweden
- 1995
-
In: Clinical Transplantation. - 0902-0063 .- 1399-0012. ; 9:4, s. 326-333
-
Journal article (peer-reviewed)abstract
- One of the aims of this study was to evaluate an information campaign carried out in three geographical areas of Sweden in the winter of 1992-93. The campaign was intended to increase public awareness of organ donation and to increase the signing of donor cards. Another objective was to test the effects of different kinds of information. These were: A) an extensive "package" of information including training of key groups, lecturing at meetings and exhibitions, and advertisements of donor cards: B) a brochure to households including two donor cards; and C) a combination of A and B. Yet another aim was to reassess public opinion on transplantation issues, which had been surveyed before in 1987, 1988, and 1990. Random samples of the population in three campaign areas and a control sample were surveyed before and after the campaign, altogether 5600 persons. The average response rate was 69% (1992) and 68% (1993). In the two areas where the brochure had been distributed to the households, the rate of donor card holders had more than doubled (from 3% and 5% to 13% and 12%). In the two areas where the brochure had not been distributed, the rate was unchanged (5%). In the "brochure areas" also a somewhat larger number of people had informed their relatives about their decisions, compared with people in the other areas. In all campaign areas considerably more people were aware of the cards than in the control area. No attitude changes could be shown in any area.(

Giving and taking - to whom and from whom? : People's attitudes toward transplantation of organs and tissue from different sources
- 1998
-
In: Clinical Transplantation. - 0902-0063 .- 1399-0012. ; 12:6, s. 515-522
-
Journal article (peer-reviewed)abstract
- The aims of the study were: 1) to describe the willingness of the public to receive material of different origins in one's own body; 2) to compare the willingness to donate and receive body material; 3) to compare the willingness to donate while alive and after death; 4) to compare the willingness to donate to a next-of-kin and unknown recipients. A random sample of 1500 inhabitants, 18 to 70 yr old, in the county of Uppsala, Sweden, were sent a questionnaire asking about their opinion on transplantation and transfusion issues. The response rate was 71%. Ninety-five percent accepted to receive blood transfusion, 89% bone-marrow transplantation, and 85% transplantation of a solid organ. Organs from living donors were preferred (77%), then organs from decreased donors (69%), then artificial organs (63%), and last animal organs (40%). More than half of those accepting transplants made exceptions for some types of organs. The youngest and those with higher education were more positive toward receiving all types of organs than the older ones and those with lower education. Women were less prepared than men to accept animal organs. Those who accepted organs from animals usually also accepted all other types of organs, and were willing to donate organs and tissue more often than those who did not accept to receive animal organs. The readiness to support a sick family member by giving bone-marrow and even a kidney was considerable, 89 and 81%, respectively. The attitudes were less positive with regard to giving blood and bone-marrow to unknown recipients, 54 and 41%, respectively. Sixty-one percent of the respondents were positive toward donating their own organs after death. Of those who were positive, 10% made exceptions for special organs that they did not want to donate, mostly heart, eyes, and brain. Individuals with higher education and young people were more often positive than those with lower education and old people regarding donation of blood and organs, and bone-marrow donation to a relative. Women were somewhat more accepting to donate while alive than males. Thirty-one percent, more often women than men, had signed a donor card and/or registered with the Swedish Organ Donation Registry. The results with regard to receiving organs and tissue are discussed in terms of two different sets of explanations, which can be seen as different sides of the same coin, and mutually strengthening the reactions. The great readiness to donate to a family member as well as the discrepancy between giving in life and after death is commented upon.

Journal article (peer-reviewed)abstract
- Islet transplantation is a minimally invasive β-cell replacement strategy. Islet transplantation is a reimbursed treatment in Norway. Here, we summarize the cost and clinical outcome of 31 islet transplantations performed at Oslo University Hospital (OUS) from January 2010 to June 2015. Patients were retrospectively divided into three groups. Thirteen patients received either one or two islet transplantation alone (ITA), while five patients received islet transplantation after previous solid organ transplantation. For the group receiving 2 ITA, Kaplan-Meier estimates show an insulin independence of 20% more than 4 years after their last transplantation. An estimated 70% maintain at least partial graft function, defined as fasting C-peptide >0.1 nmol L−1, and 47% maintain a HbA1c below 6.5% or 2 percent points lower than before ITA. For all groups combined, we estimate that 44% of the patients have a 50% reduction in insulin requirement 4 years after the initial islet transplantation. The average cost for an islet transplantation procedure was 347 297±60 588 NOK, or 35 424±6182 EUR, of which isolation expenses represent 34%. We hereby add to the common pool of growing experience with islet transplantation and also describe the cost of the treatment at our center.

- BackgroundIt is well established that post-transplantation anemia (PTA) in renal transplant recipients (RTRs) is associated with reduced graft survival. However, there is an uncertainty of the effect of PTA on cardiovascular events and all-cause mortality. We examined prospectively in a large cohort of erythropoietin-naive patients the effects of PTA on cardiovascular morbidity, patient survival, and graft survival. MethodsA prospective cohort study of RTRs (n=2102) included in the ALERT study. Cox regression models were used to evaluate the impact of PTA on study endpoints: first occurrence of a major adverse cardiac event, all-cause death, and the incidence of death-censored graft loss. Mean follow-up was 6.7yr. All endpoints were adjudicated by an independent endpoint committee. ResultsTwenty-nine percent of women and 30% of men were anemic. Hemoglobin levels were not associated with any effect on cardiovascular morbidity and mortality (HR 0.97 [0.90-1.05] per g/dL, p=0.48) or all-cause death (HR 0.96 [0.90-1.03] per g/dL, p=0.24) after extensive multivariate adjustments for clinical and demographic factors. Hemoglobin levels were negatively associated with graft loss (HR 0.86 [0.80-0.92] per g/dL, p<0.001). ConclusionsPTA was not associated with an increased incidence of cardiovascular morbidity and mortality or all-cause mortality.

- Background Graft-versus-host disease (GVHD) and relapse remain majobstacles ftreatment success in allogeneic hematopoietic stem cell transplantation (HSCT). In the present study, we evaluated the immune cell profile of the graft to outcome after HSCT.Study design and method Flow cytometry data of graft cell subsets [CD34+, CD3+, CD19+, CD4+, CD8+, CD3-CD56+CD16+, CD4+CD127lowCD25high] from G-CSF primed peripheral blood stem cell (PBSC) donors was collected retrospectively from 299 patients with hematological malignancies undergoing HSCT between 2006 and 2013. The association to overall survival, transplant-related mortality (TRM), GVHD and probability of relapse was analyzed. Patients outcome from HLA-identical sibling (Sib) (n = 97) and unrelated donors (URD) (n = 202) were analyzed separately as all URD patients received anti-thymocyte globulin (ATG).Results Five-year overall survival was similar in the two cohorts (68% (Sib) vs 65% (URD)). The relapse incidence was significantly lower in the Sib cohort (24% vs 35%, P = 0.04). Multivariate analysis in the URD group revealed an association between a higher CD8+ dose and less relapse (HR, 0.94; 95%CI, 0.90-0.98; P = 0.006) as well as an association between higher CD34+ dose and both higher TRM (HR, 1.09; 95%CI, 1.02-1.20; P = 0.02) and relapse (HR, 1.09; 95%CI, 1.01-1.17; P = 0.025). The Sib analysis showed an association between a higher graft CD19+ dose and more severe acute GVHD (HR, 1,09; 95%CI, 1.03-1.15; P = 0.003) and TRM (HR, 1.09; 95%CI, 1.01-1.17; P = 0.036). In addition, a higher CD4+ graft content was associated to an increased risk for chronic GVHD (HR, 1.02; 95%CI 1.00-1.04; P = 0.06).Conclusion These data indicate an importance of PBSC dongraft composition in patients with a hematological malignancy.
