    • Chronic graft-versus-host disease (cGVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). Aim is to identify risk factors for the development of cGVHD in a multicenter setting. Patients transplanted between 2000 and 2006 were analyzed (n = 820). Donors were HLA-identical siblings (57%), matched unrelated donors (30%), and HLA-A, B or DR antigen mismatched (13%). Reduced intensity conditioning (RIC) was given to 65% of patients. Overall incidence of cGVHD was 46% for patients surviving more than 100 days after HSCT (n = 747). Older patient age [HR 1.15, p < 0.001], prior acute GVHD [1.30, p = 0.024], and RIC [1.36, p = 0.028] increased overall cGVHD. In addition, RIC [4.85, p < 0.001], prior aGVHD [2.14, p = 0.001] and female donor to male recipient [1.80, p = 0.008] increased the risk of severe cGVHD. ATG had a protective effect for both overall [0.41, p < 0.001] and severe cGVHD [0.20, p < 0.001]. Relapse-free survival (RFS) was impaired in patients with severe cGVHD. RIC, prior aGVHD, and female-to-male donation increase the risk of severe cGVHD. ATG reduces the risk of all grades of cGVHD without hampering RFS. GVHD prophylaxis may be tailored according to the risk profile of patients.

  • Safety and Side Effects of Using Placenta-Derived Decidual Stromal Cells for Graft-versus-Host Disease and Hemorrhagic Cystitis
  • 2017
  • Ingår i: Frontiers in Immunology. - : Frontiers Media SA. - 1664-3224. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Mesenchymal stromal cells (MSCs) are increasingly used in regenerate medicine. Placenta-derived decidual stromal cells (DSCs) are a novel therapy for acute graft-versus-host-disease (GVHD) and hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (HSCT). DSCs are more immunosuppressive than MSCs. We assessed adverse events and safety using DSCs among 44 treated patients and 40 controls. The median dose of infused cells was 1.5 (range 0.9–2.9) × 106 DSCs/kg. The patients were given 2 (1–5) doses, with a total of 82 infusions. Monitoring ended 3 months after the last DSC infusion. Three patients had transient reactions during DSC infusion. Laboratory values, hemorrhages, and transfusions were similar in the two groups. The frequency of leukemic relapse (2/2, DSC/controls) and invasive fungal infections (6/6) were the same in the two groups. Causes of death were those seen in HSCT patients: infections (5/3), respiratory failure (1/1), circulatory failure (3/1), thromboembolism (1/0), multiorgan failure (0/1), and GVHD and others (2/7). One-year survival for the DSC patients with GVHD was 67%, which was significantly better than achieved previously at our center. One-year survival was 90% in the DSC-treated HC group. DSC infusions appear safe. Randomized studies are required to prove efficacy.

  • 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.

  • Oral mucositis after tacrolimus/sirolimus or cyclosporine/methotrexate as graft-versus-host disease prophylaxis
  • 2020
  • Ingår i: Oral Diseases. - : Wiley. - 1354-523X .- 1601-0825. ; 27:5, s. 1217-1225
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: To determine whether treatment with tacrolimus plus sirolimus (Tac/Sir) as a prophylaxis for graft-versus-host disease worsens severe oral mucositis and delays healing compared to cyclosporine plus methotrexate (CsA/Mtx) following haematopoietic stem cell transplantation.Subjects and methods: The study comprised 141 patients: 73 randomized to receive Tac/Sir and 68 to receive CsA/Mtx. The oral mucositis assessment scale and toxicity grading according to WHO were used to assess the severity, peak and duration of oral mucositis from the day -3 to day 24 post-transplant.Results: Eighty-seven patients developed oral mucositis in the first 24 days post-transplant. No significant difference in oral mucositis severity between the Tac/Sir and CsA/Mtx groups was observed. The peak oral mucositis score occurred on day 10 in both groups. Although oral mucositis scores had returned to baseline in the CsA/Mtx group on day 24 post-transplant, no significant difference compared with the Tac/Sir group was found.Conclusions: The introduction of tacrolimus/sirolimus as a graft-versus-host disease prophylaxis in haematopoietic stem cell transplantation increased neither the incidence nor severity of oral mucositis compared with cyclosporine/methotrexate. Furthermore, oral mucositis healing was not prolonged and followed the same time pattern as cyclosporine/methotrexate.

  • Evaluation of prognostic factors among patients with chronic graft-versus-host disease
  • 2012
  • Ingår i: Haematologica. - : Ferrata Storti Foundation (Haematologica). - 0390-6078 .- 1592-8721. ; 97:8, s. 1187-1195

    • BACKGROUND:Chronic graft-versus-host disease (cGVHD) is a major complication after allogeneic stem cell transplantation with an adverse effect on both mortality and morbidity. In 2005, the National Institute of Health proposed new criteria for diagnosis and classification of chronic graft-versus-host disease for clinical trials. New sub-categories were recognized such as late onset acute graft-versus-host disease and overlap syndrome.DESIGN AND METHODS:We evaluated the prognostic impact of the new sub-categories as well as the clinical scoring system proposed by the National Institute of Health in a retrospective, multicenter study of 820 patients undergoing allogeneic stem cell transplantation between 2000 and 2006 at 3 different institutions. Patients were retrospectively categorized according to the National Institute of Health criteria from patients' medical histories.RESULTS:As far as the new sub-categories are concerned, in univariate analysis diagnosis of overlap syndrome adversely affected the outcome. Also, the number of organs involved for a cut-off value of 4 significantly influenced both cGVHD related mortality and survival. In multivariate analysis, in addition to NIH score, platelet count and performance score at the time of cGVHD diagnosis, plus gut involvement, significantly influenced outcome. These 3 variables allowed us to develop a simple score system which identifies 4 subgroups of patients with 84%, 64%, 43% and 0% overall survival at five years after cGVHD diagnosis (score 0: HR=15.96 (95% CI: 6.85-37.17), P<0.001; score 1: HR=5.47 (95% CI: 2.6-11.5), P<0.001; score 2: HR=2.8 (95% CI: 1.32-5.93), P=0.007).CONCLUSIONS:In summary, we have identified a powerful and simple tool to discriminate different subgroups of patients in terms of chronic graft-versus-host disease related mortality and survival.

  • Improved survival after allogeneic hematopoietic stem cell transplantation in recent years : A single-center study
  • 2011
  • Ingår i: Biology of blood and marrow transplantation. - : Elsevier BV. - 1083-8791 .- 1523-6536. ; 17:11, s. 1688-1697

    • We analyzed the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) over the past 2 decades. Between 1992 and 2009, 953 patients were treated with HSCT, mainly for a hematologic malignancy. They were divided according to 4 different time periods of treatment: 1992 to 1995, 1996 to 2000, 2001 to 2005, and 2006 to 2009. Over the years, many factors have changed considerably regarding patient age, diagnosis, disease stage, type of donor, stem cell source, genomic HLA typing, cell dose, type of conditioning, treatment of infections, use of granulocyte-colony stimulating factor (G-CSF), use of mesenchymal stem cells, use of cytotoxic T cells, and home care. When we compared the last period (2006-2009) with earlier periods, we found slower neutrophil engraftment, a higher incidence of acute graft-versus-host disease (aGVHD) of grades II-IV, and less chronic GVHD (cGHVD). The incidence of relapse was unchanged over the 4 periods (22%-25%). Overall survival (OS) and transplant-related mortality (TRM) improved significantly in the more recent periods, with the best results during the last period (2006-2009) and a 100-day TRM of 5.5%. This improvement was also apparent in a multivariate analysis. When correcting for differences between the 4 groups, the hazard ratio for mortality in the last period was 0.59 (95% confidence interval [CI]: 0.44-0.79; P < .001) and for TRM it was 0.63 (CI: 0.43-0.92; P = .02). This study shows that the combined efforts to improve outcome after HSCT have been very effective. Even though we now treat older patients with more advanced disease and use more alternative HLA nonidentical donors, OS and TRM have improved. The problem of relapse still has to be remedied. Thus, several different developments together have resulted in significantly lower TRM and improved survival after HSCT over the last few years.

  • Second allogeneic hematopoietic stem cell transplantation : a treatment for graft failure
  • 2011
  • Ingår i: Clinical Transplantation. - : Wiley. - 0902-0063 .- 1399-0012. ; 25:1, s. E68-E76

    • 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.

  • Cytokine levels following allogeneic hematopoietic cell transplantation : a match-pair analysis of home care versus hospital care
  • 2021
  • Ingår i: International Journal of Hematology. - : Springer Nature. - 0925-5710 .- 1865-3774. ; 113:5, s. 712-722

    • Following allogeneic hematopoietic cell transplantation (HCT), patients living near the hospital were treated at home instead of in isolation in the hospital. We analyzed cytokines using Luminex assays for the first 3 weeks after HCT and compared patients treated at home (n = 42) with matched patients isolated in the hospital (n = 37). In the multivariate analysis, patients treated at home had decreased GM-CSF, IFN-γ (p < 0.01), IL-13, IL-5 (p < 0.05), and IL-2 (p < 0.07). Bloodstream infections, anti-thymocyte globulin, G-CSF treatment, immunosuppression, reduced-intensity conditioning (RIC), related vs. unrelated donors, and graft source affected various cytokine levels. When patients with RIC were analyzed separately, home care patients had reduced G-CSF (p = 0.04) and increased vascular endothelial growth factor (VEGF, p = 0.001) at 3 weeks compared with hospital care patients. Patients with low GM-CSF (p < 0.036) and low IFNγ (p = 0.07) had improved survival. Acute GVHD grades III–IV was seen in 7% and 16% of home care and hospital care patients, respectively. One-year transplantation-related mortality was 7% and 16% and survival at 5 years was 69% and 57% in the two groups, respectively. To conclude, patients treated in the hospital showed varying increased levels of GM-CSF, IFN-γ, IL-13, G-CSF, IL-5, and IL-2 and decreased VEGF, which may contribute to acute GVHD.

  • The Outcome of Allogeneic Hematopoietic Stem Cell Transplantation for Inherited Diseases Is Influenced by HLA Match, Year of Transplantation, and Immunized Female Donor
  • 2019
  • Ingår i: Transplantation. - : Ovid Technologies (Wolters Kluwer Health). - 0041-1337 .- 1534-6080. ; 103:6, s. 1247-1252
  • Tidskriftsartikel (refereegranskat)abstract
    • Background For many inborn errors of metabolism (IEM), allogeneic hematopoietic stem cell transplantation (HSCT) is the only cure.Methods We report the outcome in 160 patients with inherited diseases, who were treated with HSCT in 3 decades. Median age was 3 years (range 0.1-63). Grafts were from matched related donors (MRDs, 56), matched unrelated donors (MUDs, 66), or HLA-mismatched donors (38).Results Graft failure (GF) occurred in 26 patients (16%), severe acute graft-versus-host disease (GVHD) in 9 (6%), and chronic GVHD in 23 (12%). Ten-year survival was 64% before the year 2000 and 86% after that (P = 0.01). Ten-year survival for MRD grafts was 90%, as opposed to 79% for MUD grafts and 56% for HLA-mismatched grafts (P = 0.03). In multivariate analysis, GF was associated with having an HLA-mismatched donor (P < 0.05) or MUD (P = 0.015) and with reduced-intensity conditioning (P < 0.01). Death was associated with year of transplant (P = 0.015), having an HLA-mismatched donor (P < 0.001), and being a male recipient from an immune female donor (P = 0.05).Conclusions The outcome after HSCT for IEM depends on HLA match, year and immune female donor.

  • Transplantation of Autologous and Allogeneic Bone Marrow With Liver From A Cadaveric Donor for Primary Liver Cancer1
  • 2000
  • Ingår i: Transplantation. - : Ovid Technologies (Wolters Kluwer Health). - 0041-1337 .- 1534-6080. ; 69:10, s. 2043-2048

    • BackgroundIn histocompatibility mismatched experimental animals, a combination of T-cell-depleted autologous and allogeneic marrow may induce mixed chimerism and tolerance. Patients with large primary liver tumors have a poor outcome. We investigated whether it were possible to induce mixed chimerism and obtain an antitumor effect in a patient with a large primary liver cancer after combined liver and bone marrow transplantation (BMT).MethodsA 46-year-old female with a primary non resectable liver cancer received a liver transplant from a cadaveric donor. Subsequently, she was conditioned with 4×2 Gy of total lymphoid irradiation, 120 mg/kg cyclophosphamide, and 7.5 Gy total body irradiation. Twelve days after liver transplantation, she received T-cell-depleted autologous : cadaveric 5/6 antigen HLA-mismatched marrow in a proportion of CD34+ cells of 0.5 : 3.0×106/kg. Chimerism status was determined with polymerase chain reaction amplification of variable number tandem repeats from DNA obtained from CD3+, CD19+, and CD45+ magnetic-bead-separated cells.ResultsThe early posttransplant period was uneventful; liver function was normal and the hematopoietic engraftment of donor and recipient origin was prompt. [alpha]-fetoprotein levels dropped from 440 to 35 µg/l. One month after marrow transplantation, donor T-cells decreased markedly. Monoclonal antibody OKT-3 and 105/kg donor T-cells were given. One month later, the patient developed diarrhea and abdominal pain. A colonoscopy showed moderate gastrointestinal acute graft-versus-host disease and a Cryptosporidium infection. Three months after BMT, she became a complete donor chimera. Chimera cells showed little, if any, reactivity in mixed lymphocyte cultures to recipient and donor cells, but reacted to third party. Five months after BMT, she developed progressive Aspergillus fumigatus pneumonia and died. No tumor was found at the autopsy.ConclusionWe obtained mixed donor-recipient hematopoietic chimerism without severe acute graft-versus-host-disease, after combined T-cell depleted autologous and allogeneic BMT and a transplantation of a liver from an HLA-mismatched cadaveric donor. Additional donor T-cells enhanced donor bone marrow engraftment, but rejected the autograft. On the basis of this first attempt, further clinical studies are warranted.
