- Our main goal with this study was to share our off-label experience with CEUS for identifying circulatory complications after liver transplantation in children. A total of 74 CEUS examinations performed on 34 pediatric patients who underwent a liver transplant were retrospectively included. About 53% of the examinations were performed on children 2 years old or younger. About 82% of the examinations were performed within 30 days from the transplant. About 62% of patients were transplanted due to a cholestatic disease, 11% due to a metabolic disease, 8% were re-transplanted due to graft failure, and 19% was due to other conditions. BA was the most common reason for transplantation and represented 38% of patients. About 38% of the transplantations were performed with whole grafts from DD, 40% with split liver grafts, and 22% with left lateral segments from LD. For diagnosing arterial circulatory complications, the PPV was 80%. For diagnosing portal vein circulatory complications, the PPV was 66.7%. NPV was 100%. In 28% of the examinations, the examiner could not visualize the normal arterial blood flow without CEUS. CEUS is a non-invasive and safe imaging technique that seems valuable in these patients and further efforts are needed to license its use in the post-transplant setting.

- TEN and HUS are challenging complications with excessive mortality after HSCT. We report the development of these two conditions in combination in a nine-yr-old boy after HSCT from an unrelated donor. TEN with skin detachment of more than 90% of body surface area developed after initial treatment for GvHD. Within a few days of admission to the burns unit, the patient developed severe hemolysis, hypertension, thrombocytopenia, and acute renal failure consistent with HUS, apparently caused by CSA. The management included intensive care in a burns unit, accelerated drug removal using plasmapheresis, and a dedicated multi-disciplinary team approach to balance immunosuppression and infections management in a situation with extensive skin detachment. The patient survived and recovered renal function but requires continued treatment for severe GvHD. Suspecting and identifying causative drugs together with meticulous supportive care in the burns unit is essential in the management of these patients and long-term survival is possible.

- The Transplantation Society, in collaboration with the Canadian Society of Transplantation, organized a forum on education on ODT for schools. The forum included participants from around the world, school boards, and representatives from different religions. Participants presented on their countries' experience in the area of education on ODT. Working groups discussed about technologies for education, principles for sharing of resources globally, and relationships between education, and health authorities and non-governmental organizations. The forum concluded with a discussion about how to best help existing programs and those wishing to start educational programs on ODT.

Shear wave elastography and shear wave dispersion correlated to biopsy at the scheduled follow-up of pediatric liver grafts
- 2023
-
Ingår i: Pediatric Transplantation. - 1397-3142. ; 27:7
-
Tidskriftsartikel (refereegranskat)abstract
- Background: It is unknown how shear wave dispersion (SWD) is displayed in pediatric liver transplant recipients and not fully elucidated how ultrasound shear wave elastography (2D-SWE) display within this cohort, which is important to determine to improve noninvasive surveillance of these patients. The study aimed to compare SWE and SWD values with histopathology in pediatric liver recipients.Methods: Forty-eight pediatric liver recipients were examined with SWE in conjunction with an elective liver biopsy (clinically without complication). Additionally, SWD values were measured in 21 children. SWE and SWD values were compared to histologically determined fibrosis graded as none-to-mild (F0-1) and moderate-to-severe (F2-4), and inflammation graded as low (grade 0-1) and high (grade 2-4).Results: Two children were excluded due to SWE IQR/median > 30% kPa. The mean age across 46 included patients was 10.9 years (range 1.4-18). The number of patients and median (range) SWE value (kPa) for each stage of fibrosis were: F0-1 [n = 23; 5.8 (3.2-16.1)], F2 [n = 22; 6.0 (4.5-25.9)], F3 [n = 1; 33.3], and F4 [n = 0]. Significantly higher SWE values and greater variability were registered in F2-4 vs. F0-1 (p = .05). Grade of fibrosis correlated weakly to SWE values (r = .3; p = .05), but not to SWD values (r = .2; p = .27). In patients with low-grade inflammation, median SWD was 13.7 m/s KHz (10.7-17.6). Only one patient had high-grade inflammation.Conclusions: Uncomplicated transplanted liver grafts in a small pediatric cohort revealed slightly increased SWE and SWD values compared to previously reported values in healthy children. This likely reflect both the fibrotic and inflammatory elements in the grafts; however, other confounders impacting the liver's viscoelastic properties are also probable factors.

Four-year data after pediatric renal transplantation: a randomized trial of tacrolimus vs. cyclosporin microemulsion
- 2005

Ingår i: Pediatric transplantation. - 1397-3142. ; 9:4, s. 498-503

Tidskriftsartikel (refereegranskat)abstract
- This study was undertaken to compare the efficacy and safety of tacrolimus (Tac) with cyclosporin microemulsion (CyA) in pediatric renal recipients. A 6-month, randomized, prospective, open, parallel group study with an open extension phase was conducted in 18 centers from nine European countries. In total, 196 pediatric patients (<18 yr) were randomly assigned (1:1) to receive either Tac (n = 103) or CyA (n = 93) administered concomitantly with azathioprine and corticosteroids. The primary endpoint was incidence and time to first acute rejection (intent-to-treat). Baseline characteristics were comparable between treatment groups. Excluding deceased patients (n = 9) and patients lost to follow-up (n = 31, mostly transferred to adult care), 95% of 2-yr data (159 of 167 possible patients), 87% of 3-yr data (142 of 163) and 73% of 4-yr data (114 of 156) were retrieved. At 1 yr Tac therapy resulted in a significantly lower incidence of acute rejection (36.9%) compared with CyA (59.1%, p = 0.003). The incidence of corticosteroid-resistant rejection was also significantly lower with Tac (7.8% vs. 25.8%, p = 0.001). At 4 yr, patient survival was similar (94% vs. 92%, p = 0.86) but graft survival significantly favored Tac (86% vs. 69%; p = 0.025, log-rank test), respectively. At 1 yr, the mean glomerular filtration rate (GFR) (Schwartz formula, ml/min/1.73 m(2)) was 64.9 +/- 20.7 (n = 84) vs. 57.8 +/- 21.9 (n = 77, p = 0.0355), at 2 yr 64.9 +/- 19.8 (n = 71) vs. 51.7 +/- 20.3 (n = 66, p = 0.0002), at 3 yr 66.7 +/- 26.4 (n = 81) vs. 53.0 +/- 23.3 (n = 55, p = 0.0022), and at 4 yr 71.5 +/- 22.9 (n = 51) vs. 53.0 +/- 21.6 (n = 44, p = 0.0001) for Tac vs. CyA, respectively. Cholesterol remained significantly higher with CyA throughout follow-up. Three patients in each arm developed post-transplant lymphoproliferative disease. Incidence of insulin-dependent diabetes mellitus was not different. Tac was significantly more effective than CyA in preventing acute rejection in pediatric renal recipients. Renal function and graft survival were also superior with Tac. Glomerular filtration rate appears to be an useful surrogate marker for long-term outcome.

Tidskriftsartikel (refereegranskat)abstract
- There is insufficient knowledge about the quality of life (QoL) among children after allogeneic stem cell transplantation (SCT). We recently reported an overall, good self-assessed QoL and health in 52 children who were three yr or more beyond SCT. The focus of this paper is the QoL as assessed by their parents, of whom 42 participated in the study. Using Swedish child health questionnaire (SCHQ)-PF50, parents rated their children's QoL lower on both the psychosocial (p<0.001) and physical summary scales (p<0.001) than the normative group of parents of children without chronic disease. Although essentially following each other, parent scores tended to be lower than children's own SCHQ-CF87 scores, particularly in the domains 'role socially due to physical limitations' (p<0.01) and 'self-esteem' (p<0.05). In the 'bodily pain' domain, patients' and parents' low scores agreed. The child's condition had a greater impact on parents' emotional situation than in the norm population (p<0.001). The severity of the child's physician-rated late effects (p<0.05) or of self-assessed subjective symptoms (p<0.01-0.05) was associated with a lower parental rating of the child's QoL. High Lansky or Karnofsky scores corresponded, respectively, to higher psychosocial (p<0.05) and physical (p<0.05) summary scores. It is concluded that as children, parents, and clinicians do not necessarily adopt similar views of a child's illness and of its impact on the child's life, clarity with regard to who is responsible for assessing the child's QoL is crucial when interpreting pediatric QoL studies.

Tidskriftsartikel (refereegranskat)abstract
- The use of living parental liver donors will continue and probably increase because of lack of cadaveric livers for paediatric transplantation and the excellent graft survival of parental livers. Therefore, it is important for the health care professionals involved in living parental liver donation to understand the experience of being a liver donor. The aim of this study was to investigate the expressed deeper feelings of parents who donated a part of their liver to their own child. The study took the form of in-depth interviews with 11 donors. All donors were biological parents of the recipient, nine fathers and two mothers. The interpretive phenomenology method was used, and interpretive analysis was carried out in three interrelated processes in line with Benner. Data collection was guided by the researcher's preliminary understanding of the donor experience from being involved in the surgery and care of the donors as well as the paediatric recipients. However, the research question was approached from the perspective of holistic care for the donor. In this study, the essence of living parental liver donation was found to be the struggle for holistic confirmation. There were three categories leading to this central theme; the total lack of choice, facing the fear of death and the transition from health to illness. There was total agreement among the respondents that there is no choice when it comes to the question of donation. The findings in this study stress the importance of organizing the parental liver donation programme with as much focus on the donor as on the child. Based on the results of this study, several clinical implications are suggested for the formation of guidelines for living parental liver donation.

- Parathyroid function was recently reported to be affected in more than one-third of pediatric BMT patients conditioned without irradiation. Our aim was to describe parathyroid function in children with malignant hematological disease after autologous BMT with and without TBI. PTH, albumin-corrected serum calcium, and serum phosphate were analyzed in 35 children followed for six months to nine yr after BMT. Twelve patients were conditioned with chemotherapy alone, and 23 patients received TBI as well. In the TBI group, 11 patients had previously received additional CRT. We found normal levels of PTH in children post-BMT, with the exception of four patients (11%) who showed transient PTH elevation during the first year of follow-up, There was no difference between those who had received irradiation and those who had not. Serum calcium was unchanged after BMT. An age-corrected quotient of serum phosphate decreased slightly. Renal function which was normal before BMT decreased slightly in both groups after BMT, but was within the normal range. Parathyroid function was found to be normal during the time frame of this study, irrespective of whether irradiation had been given.

- We measured risk factors for CVD in 18 patients at a median of 18.2 yr after SCT and in sex and age-matched controls. Three patients (17%), but none of the controls, met the criteria for the MetS (p = 0.25). In the patients, we found higher levels of triglycerides (0.94 vs. 0.62 mm, p = 0.019), total cholesterol (5.1 vs. 4.0 mm, p = 0.017), LDL (3.4 vs. 2.6 mm, p = 0.019), apolipoprotein B (1.04 vs. 0.74 g/L, p = 0.004), apolipoprotein B/A1 ratio (0.7 vs. 0.5, p = 0.026), and lower levels of adiponectin (4.9 vs. 7.5 mg/L, p = 0.008) than in the controls. The patients had a lower GHmax (9 vs. 20.7 mU/L, p = 0.002). GHmax was significantly correlated inversely with triglycerides (r = -0.64, p = 0.008), total cholesterol (r = -0.61, p = 0.011), apolipoprotein B (r = -0.60, p = 0.014), and apolipoprotein B/A1 ratio (r = -0.66, p = 0.005). We recorded a significantly thicker carotid intima layer among the patients than among matched controls (0.15 vs. 0.13 mm, p = 0.034). The level of adiponectin correlated inversely with carotid intima thickness (r = -0.55, p = 0.023). After SCT in childhood, long-term survivors may be at risk of developing premature CVD.

- Small pediatric recipients of an adult-sized kidney have insufficient renal blood flow early after transplantation, with secondary chronic hypoperfusion and irreversible histological damage of the tubulo-interstitial compartment. It is unknown whether this is reflected by renal resistive indices. We measured renal graft resistive indices and volumes of 47 healthy pediatric kidney transplant recipients of an adult-sized kidney in a prospective study for six months post-transplant. A total of 205 measurements were performed. The smallest recipients (BSA /= 1.5 m(2) (p < 0.0001). Resistive indices increased during the first six months in the smallest recipients (p = 0.02), but not in the two larger recipient groups (BSA 0.75-1.5 m(2) and >/=1.5 m(2)). All three BSA groups showed a reduction in renal volume after transplantation, with the greatest reduction occurring in the smallest recipients. In conclusion, renal transplant resistive indices reflect pediatric recipient BSA dependency. The higher resistance to intra-renal vascular flow and significant decrease in renal volume in the smallest group likely reflect accommodation of the size discrepant transplanted adult-sized kidney to the smaller pediatric recipient vasculature with associated lower renal artery flow.

- Long-term exposure to calcineurin inhibitors increases the risk of CKD in children after LT. The aims of this study were to study renal function by measuring GFRm before and yearly after LT, to describe the prevalence of CKD (stage III: GFR 30-60 mL/min/1.73 m(2)) and to investigate if age and underlying liver disease had an impact on long-term renal function. Thirty-six patients with a median age of 2.9 years (0.1-16 yr) were studied. Median follow-up was 6.5 (2-14 yr). GFRm decreased significantly during the first six months post-transplantation with 23% (p < 0.001). Thereafter renal function stabilized. At six months, 17% (n = 5) of the children presented CKD stage III and at five yr the prevalence of CKD III was 18% in 29 children. However, in 13 children with a 10-year follow-up it was 0%. None of the children required renal replacement therapy after LT. When analyzing renal function of those children younger than two yr (n = 14) and older than two yr (n = 17) at the time of transplantation, we found that in both cohorts the filtration rate remained remarkably stable during the five-yr observational period. However, there was a statistically significant (p < 0.05) difference in the percentual decrease in GFRm between the groups during the first six months after LT 13% and 31%, respectively. Baseline GFRm according to diagnosis did not differ between the groups. During the first six months after LT, patients transplanted for hepatic malignancy (n = 6) and those with metabolic liver disease (n = 4) had a percentage loss of GFRm of 32% and 35%, respectively. The corresponding loss of GFRm in patients with other diseases was 10-19%. Six months post-transplantation mean GFRm in the group with malignant liver disease was 65 +/- 15 mL/min/1.73 m(2) and in the group with other diseases (n = 24) 82 +/- 17 mL/min/1.73 m(2) (p < 0.05). At one, three and five yr post-transplantation there was no longer a statistically significant difference between these cohorts. Our findings suggest that there can be a long-term recovery of renal function after LT in children.

- We report on the reversal of protein-losing enteropathy (PLE) after heart transplantation (HTx) in a 10-yr-old boy with Fontan circulation, previously treated unsuccessfully with heparin for several months. The protein loss continued immediately after the Tx. During the following month, however, a gradual decrease in protein loss was observed, which correlated with a decrease in the inferior vena cava (IVC) pressure. The patient is doing well with a normal serum albumin level and a normal IVC pressure, 2 yr after Tx.

International practice heterogeneity in pre-transplant management of pulmonary hypertension related to pediatric left heart disease

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Elevated pulmonary vascular resistance (PVR) in the setting of left heart failure may contribute to poor outcomes after pediatric heart transplant (HTx), but peri-transplant management is variable.METHODS: We sought to characterize international practice by surveying physicians at pediatric HTx centers.RESULTS: We received 49 complete responses from 39 centers in 16 countries. Most respondents are pediatric cardiologists (90%), practice at centers offering heart (86%) and lung (55%) transplant, and perform pre-HTx acute vasoreactivity testing (AVT, 88%) in patients with elevated PVR. Half (51%) reported defining a PVR cutoff for HTx eligibility as ≤6 WU m 2 (56%) post-AVT (84%). The highest post-AVT PVR ever accepted for HTx ranged from 3-14.4 (median 6) WU m 2 . To treat elevated pre-transplant PVR, phosphodiesterase type 5 inhibitors are most common (65%) followed by oxygen (31%), nitric oxide (14%), endothelin receptor antagonists (11%), and prostacyclins (6%). Nearly a third (31%) do not routinely use pulmonary vasodilators without implantation of a left ventricular assist device (LVAD). Case scenarios highlight treatment variability: in a restrictive cardiomyopathy scenario, HTx listing with post-transplant vasodilator therapy was favored, whereas in a Shone's complex patient with fixed PVR, LVAD ± pulmonary vasodilators followed by repeat catheterization was most common. Management of dilated cardiomyopathy with reactive PVR was variable. Most continue vasodilator therapy until HTx (16%), PVR normalizes (16%) or ≤6 months. CONCLUSIONS: Management of elevated PVR in children awaiting HTx is heterogenous. Evidence-based guidelines are needed to allow for longitudinal determination of optimal outcomes and standardized care.
