  • Higher response rates in patients with severe chronic skin graft-versus-host disease treated with extracorporeal photopheresis
  • 2019
  • Ingår i: Central European Journal of Immunology. - : TERMEDIA PUBLISHING HOUSE LTD. - 1426-3912 .- 1644-4124. ; 44:1, s. 84-91
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Different forms of graft-versus-host disease (GVHD) remain a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). The prognosis for steroid-refractory chronic GVHD (cGVHD) remains poor. Our aim was to evaluate extracorporeal photopheresis (ECP) treatment in cGVHD patients with different organ involvement to detect subgroups of patients with the best response.Material and methods: Thirty-four patients who underwent HSCT and developed moderate (n = 7) or severe (n = 27) steroid-refractory or steroid-dependent cGVHD treated with ECP were included in the analysis. A matched cGVHD control patient group untreated with ECP was collected for comparison.Results: Compared to the control group and the stable/progressive disease (SD/PD) patients, individuals with complete/partial remission have higher overall survival and lower transplant-related mortality. Furthermore, patients with complete and partial remission (CR/PR) had significantly higher levels of albumin and platelets after ECP treatment compared to patients with stable or progressive cGVHD (SD/PD). Corticosteroid treatment and other immunosuppressive agents could successfully be tapered in the CR/PR group compared to the SD/PD patients. In this study patients with skin cGVHD are those with the highest rate of CR/PR after ECP treatment.Conclusions: Our results suggest that ECP treatment is safe and effective for patients with predominantly skin, oral and liver cGVHD.

  • General health, symptom occurrence, and self-efficacy in adult survivors after allogeneic hematopoietic stem cell transplantation : a cross-sectional comparison between hospital care and home care
  • 2015
  • Ingår i: Supportive Care in Cancer. - : Springer Science and Business Media LLC. - 0941-4355 .- 1433-7339. ; 23:5, s. 1273-83
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Earlier studies have shown that home care during the neutropenic phase after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is medically safe, with positive outcomes. However, there have been few results on long-term outcomes after home care. The aims of this study were to compare general health, symptom occurrence, and self-efficacy in adult survivors who received either home care or hospital care during the early neutropenic phase after allo-HSCT and to investigate whether demographic or medical variables were associated with general health or symptom occurrence in this patient population.METHODS: In a cross-sectional survey, 117 patients (hospital care: n = 78; home care: n = 39) rated their general health (SF-36), symptom occurrence (SFID-SCT, HADS), and self-efficacy (GSE) at a median of 5 (1-11) years post-HSCT.RESULTS: No differences were found regarding general health, symptom occurrence, or self-efficacy between groups. The majority of patients in both hospital care (77 %) and home care (78 %) rated their general health as "good" with a median of 14 (0-36) current symptoms. Symptoms of fatigue and sexual problems were among the most common. Poor general health was associated with acute graft-versus-host disease (GVHD), low self-efficacy, and cord blood stem cells. A high symptom occurrence was associated with female gender, acute GVHD, and low self-efficacy.CONCLUSIONS: No long-term differences in general health and symptom occurrence were observed between home care and hospital care. Thus, home care is an alternative treatment method for patients who for various reasons prefer this treatment option. We therefore encourage other centers to offer home care to patients.

  • Granulocyte transfusions could benefit patients with severe oral mucositis after allogeneic hematopoietic stem cell transplantation
  • 2019
  • Ingår i: Vox Sanguinis. - : Wiley-Blackwell. - 0042-9007 .- 1423-0410. ; 114:7, s. 769-777
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and objectives Mucositis is a common complication after allogeneic hematopoietic stem cell transplantation (HSCT), and is caused by a combination of conditioning-induced mucosal damage and severe neutropenia. The symptoms include oral and abdominal pain, inability to swallow food and fluids, and severe diarrhoea. Severe mucositis is associated with increased risk of Graft-versus-Host disease and infection. Granulocyte transfusions (GCX) could be a treatment option, and our objective was to study its feasibility and potential benefits. Material and methods This retrospective, single-centre study included 30 patients receiving GCX because of severe oral mucositis after HSCT during 2005-2017. Clinical outcome, response to GCX, change in opiate administration and adverse events were studied. Results Twenty-seven patients received GCX from donors pre-treated with steroids and G-CSF, and three from donors pre-treated with steroids only. Overall response was 83% (24/29 evaluable patients). Fifteen patients reached a complete response. In 14 of 24 responders, a reduction of the administration of opiate pain relief was seen. In eight patients this reduction was >= 50% of the dose. Adverse events (AEs) were reported in 14 cases, and were mild to moderate, and well manageable with symptomatic treatment. No life-threatening or fatal AEs were recorded. Conclusions These results indicate that GCX could be a safe and effective treatment for oral mucositis after HSCT with the potential to reduce the necessity of opiate analgesic treatment in this disorder. No severe AEs were seen in this study, but the risk for severe pulmonary AEs after GCX needs to be considered.

  • Bloodstream Infections and Outcomes Following Allogeneic Hematopoietic Cell Transplantation : A Single-Center Study
  • 2022
  • Ingår i: Transplantation and Cellular Therapy. - : Elsevier. - 2666-6375 .- 2666-6367. ; 28:1, s. 50.e1-50.e8
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated the single-center incidence and risk factors for bloodstream infections (BSIs) in 651 adults who underwent allogeneic hematopoietic cell transplantation (alloHCT) between 2015 and 2019 and explored the impact of these BSIs on post-transplantation outcomes. Antibiotic prophylaxis with ciprofloxacin was given during the aplastic phase. Overall, the median patient age was 57 years, 79.7% of patients received an alternative donor graft, and 68.7% received post-transplantation cyclophosphamide (PTCy) as part of their graft-versus-host disease (GVHD) prophylaxis. Of the 651 patients, 358 (55.0%) had at least 1 episode of BSI, and the overall mortality rate secondary to this complication was 7.5% (12.6% among those diagnosed with at least 1 episode of BSI). BSI was more often diagnosed during the first 30 days (58.7%), and gram-positive bacteria were the most prevalent microorganisms isolated during the entire post-transplantation follow-up (62%). A high Disease Risk Index (hazard ratio [HR], 1.47; P < .029) and receipt of PTCy-based GVHD prophylaxis (HR, 3.33; P < .001) were identified as risk factors for BSI. Additionally, univariate analysis showed that patients diagnosed with a BSI during post-transplantation follow-up had worse overall survival (HR, 2.48; P < .001) and higher nonrelapse mortality (HR, 2.68; P < .001) than those without BSI. In conclusion, alloHCT recipients with a BSI had a higher risk of mortality compared with those who did not develop BSI. The inclusion of PTCy as part of GVHD prophylaxis was identified as an independent risk factor for BSI during early post-transplantation follow-up. Single-center analyses focused on reporting the incidence and risk factors for BSI highlight the need for active implementation of preemptive strategies to decrease BSI incidence in the alloHCT setting.

  • Interaction Between High-Dose Intravenous Busulfan and Post-Transplantation Cyclophosphamide on Hemorrhagic Cystitis After Allogeneic Hematopoietic Cell Transplantation
  • 2023
  • Ingår i: Transplantation and Cellular Therapy. - : Elsevier. - 2666-6375 .- 2666-6367. ; 29:9, s. 581.e1-581.e8
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigates the incidence and predictors of hemorrhagic cystitis (HC) in 960 adults undergoing allo- hematopoietic stem cell transplantation. Two hundred fifty-two (26.5%) patients received myeloablative conditioning regimens, and 81.4% received high-dose intravenous busulfan (HD Bu). Six hundred ninety-five (72.4%) patients received post-transplantation cyclophosphamide (PTCY)-based prophylaxis, and 91.4% additionally received anti-thymocyte globulin (ATG) and Cyclosporine A (CsA) (PTCY-ATG-CsA). Two hundred twenty-eight (23.8%) patients developed HC. The day 100 cumulative incidences of grades 2-4 and 3-4 HC were 11.1% and 4.9%. BK virus was isolated in 58.3% of urinary samples. Using HD BU myeloablative regimens increased the risk for grade 2-4 HC (hazard ratio [HR] = 1.97, P = .035), and HD BU combined with ATG-PTCY-CsA increased this 4 times (HR = 4.06, P < .001) for grade 2-4 HC compared to patients who received neither of these drugs. A significant correlation was documented between grade II-IV acute graft-versus-host disease and grade 2-4 HC (HR = 2.10, P < .001). Moreover, patients with BK-POS grade 2-4 HC had lower 1-year overall survival (HR = 1.51, P = .009) and higher non-relapse mortality (HR = 2.31, P < .001), and patients with BK-NEG grade 2-4 HC had comparable post-transplantation outcomes. In conclusion, intravenous HD Bu was identified as a predictor for grade 2-4 HC. Moreover, when HD Bu was combined with PTCY-ATG-CsA, the risk increased 4-fold. Based on the results provided by this study, preventing the onset of HC, especially in high-risk patients, is mandatory because its presence significantly increases the risk for mortality.

  • Multicenter evaluation of parametric response mapping as an indicator of bronchiolitis obliterans syndrome after hematopoietic stem cell transplantation
  • 2020
  • Ingår i: American Journal of Transplantation. - : Wiley. - 1600-6135 .- 1600-6143. ; 20:8, s. 2198-2205
  • Tidskriftsartikel (refereegranskat)abstract
    • Parametric response mapping (PRM) is a novel computed tomography (CT) technology that has shown potential for assessment of bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation (HCT). The primary aim of this study was to evaluate whether variations in image acquisition under real-world conditions affect the PRM measurements of clinically diagnosed BOS. CT scans were obtained retrospectively from 72 HCT recipients with BOS and graft-versus-host disease from Fred Hutchinson Cancer Research Center, Karolinska Institute, and the University of Michigan. Whole lung volumetric scans were performed at inspiration and expiration using site-specific acquisition and reconstruction protocols. PRM and pulmonary function measurements were assessed. Patients with moderately severe BOS at diagnosis (median forced expiratory volume at 1 second [FEV1] 53.5% predicted) had similar characteristics between sites. Variations in site-specific CT acquisition protocols had a negligible effect on the PRM-derived small airways disease (SAD), that is, BOS measurements. PRM-derived SAD was found to correlate with FEV1% predicted and FEV1/ forced vital capacity (R = −0.236, P = .046; and R = −0.689, P < .0001, respectively), which suggests that elevated levels in the PRM measurements are primarily affected by BOS airflow obstruction and not CT scan acquisition parameters. Based on these results, PRM may be applied broadly for post-HCT diagnosis and monitoring of BOS.

  • Reduced Risk of Sinusoidal Obstruction Syndrome of the Liver after Busulfan-Cyclophosphamide Conditioning Prior to Allogeneic Hematopoietic Stem Cell Transplantation
  • 2020
  • Ingår i: Clinical and Translational Science. - : Wiley. - 1752-8054 .- 1752-8062. ; 13:2, s. 293-300
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study is to evaluate the incidence of sinusoidal obstruction syndrome (SOS) of the liver and the clinical outcome after hematopoietic stem cell transplantation (HSCT) based on several modifications in our protocols. We retrospectively investigated 372 patients undergoing myeloablative conditioning with oral busulfan (Bu) and cyclophosphamide before allogeneic HSCT during 1990-2015. Patients' supportive care was changed in order to reduce the regimen-related toxicities. Norethisterone use was terminated in 1998, therapeutic drug monitoring of Bu was initiated in 2000, and the use of liver supportive drugs, such as ursodeoxycholic acid and N-acetyl-L-cysteine, were started in 2002 and 2009, respectively. In total, 26 patients (7.0%) developed SOS at a median of 19 days after transplantation. Of these 26 patients, 20 died at a median of 119 days after HSCT and 102 days after the diagnosis of SOS. The incidence of SOS decreased over time in accordance with the improvements in supportive care. The highest incidence of SOS was during 1995-1999 (16.2%) compared with 2.3% during 2010-2015. Overall survival for patients with SOS was 62%, 46%, and 27% at 100 days, 1 year, and 5 years after HSCT, respectively, compared with 92%, 77%, and 66% for those who did not develop SOS (P < 0.001). In conclusion, the incidence of SOS and related deaths were significantly decreased over the last years. Our institution pursues massive preventative and personalized measures for SOS. This strategy may also be applicable in other conditioning protocols in order to reduce the incidence of SOS and, hence, improve the clinical outcome.

  • The effect of N-acetyl-l-cysteine (NAC) on liver toxicity and clinical outcome after hematopoietic stem cell transplantation
  • 2018
  • Ingår i: Scientific Reports. - : NATURE PUBLISHING GROUP. - 2045-2322. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Busulphan (Bu) is a myeloablative drug used for conditioning prior to hematopoietic stem cell transplantation. Bu is predominantly metabolized through glutathione conjugation, a reaction that consumes the hepatic glutathione. N-acetyl-l-cysteine (NAC) is a glutathione precursor used in the treatment of acetaminophen hepatotoxicity. NAC does not interfere with the busulphan myeloablative effect. We investigated the effect of NAC concomitant treatment during busulphan conditioning on the liver enzymes as well as the clinical outcome. Prophylactic NAC treatment was given to 54 patients upon the start of busulphan conditioning. These patients were compared with 54 historical matched controls who did not receive NAC treatment. In patients treated with NAC, aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) were significantly (P amp;lt; 0.05) decreased after conditioning compared to their start values. Within the NAC-group, liver enzymes were normalized in those patients (30%) who had significantly high start values. No significant decrease in enzyme levels was observed in the control group. Furthermore, NAC affected neither Bu kinetics nor clinical outcome (sinusoidal obstruction syndrome incidence, graft-versus-host disease and/or graft failure). In conclusion: NAC is a potential prophylactic treatment for hepatotoxicity during busulphan conditioning. NAC therapy did not alter busulphan kinetics or affect clinical outcome.

  • Patient age and donor HLA matching can stratify allogeneic hematopoietic cell transplantation patients into prognostic groups
  • 2022
  • Ingår i: European Journal of Haematology. - England : John Wiley & Sons. - 0902-4441 .- 1600-0609. ; 109:6, s. 672-679
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Mixed results surround the accuracy of commonly used prognostic risk scores to predict overall survival (OS) and non-relapse mortality (NRM) in allogeneic hematopoietic stem cell transplant (allo-HCT) recipients. We hypothesize that a simple prognostic score performs better than conventional scoring systems.Patients and methods: OS risk factors, HCT-CI, age-HCT-CI, and augmented-HCT-CI were studied in 299 patients who underwent allo-HCT for myeloid and lymphoid malignancies. A scoring system was developed based on results and validated in a different cohort of 455 patients.Results: Two-year OS was 51% (95% confidence interval (CI) 0.45–0.56); 2-year NRM was 34% (95% CI 0.29–0.39). HCT-CI and associated scores were grouped into 0–2 and ≥3. Age and HLA mismatch status were the only risk factors to affect OS in multivariate analysis (p = 0.02 and 0.05, respectively). HCT-CI and associated scores were not informative for OS prediction. The weighted scoring system assigned 0 to 2 points for age < 50, 50–64, or ≥65, respectively, and 0–1 points for no HLA mismatch versus any mismatch (except HLA-DQ). Distinct 2-year OS (62%, 53%, and 38% [p = <0.001]) and NRM (24%, 34%, and 43% [p = 0.02]) groups were characterized. The scoring system was validated in a second independent cohort with similar results on OS and NRM (p < 0.001).Conclusions: A simple scoring system based on recipient's age and mismatch status accurately predict OS and NRM in two distinct cohorts of allo-HCT patients. Its simplicity makes it a helpful tool to aid clinicians and patients in clinical decision-making.
