Abstract: Background: Non-adherence with immunosuppressant medication (MNA) fosters development of de novo donor-specific antibodies (dnDSA), rejection, and graft failure (GF) in kidney transplant recipients (KTRs). However, there is no simple tool to assess MNA, prospectively. The goal was to monitor MNA and analyze its predictive value for dnDSA generation, acute rejection and GF. Methods: We enrolled 301 KTRs in a multicentric French study. MNA was assessed prospectively at 3, 6, 12, and 24 months (M) post-KT, using the Morisky scale. We investigated the association between MNA and occurrence of dnDSA at year 2 post transplantation, using logistic regression models and the association between MNA and rejection or graft failure, using Cox multivariable models. Results: The initial percentage of MNA patients was 17.7%, increasing to 34.6% at 24 months. Nineteen patients (8.4%) developed dnDSA 2 to 3 years after KT. After adjustment for recipient age, HLA sensitization, HLA mismatches, and maintenance treatment, MNA was associated neither with dnDSA occurrence, nor acute rejection. Only cyclosporine use and calcineurin inhibitor (CNI) withdrawal were strongly associated with dnDSA and rejection. With a median follow-up of 8.9 years, GF occurred in 87 patients (29.0%). After adjustment for recipient and donor age, CNI trough level, dnDSA, and rejection, MNA was not associated with GF. The only parameters associated with GF were dnDSA occurrence, and acute rejection. Conclusions: Prospective serial monitoring of MNA using the Morisky scale does not predict dnDSA occurrence, rejection or GF in KTRs. In contrast, cyclosporine and CNI withdrawal induce dnDSA and rejection, which lead to GF.

Abstract: Background Donor-specific antibodies (DSA) play a major role in antibody-mediated rejection (AMR) and graft dysfunction. However, the clinical relevance of complement-binding anti-HLA antibodies remains unclear. Methods Here, we analyzed DSA detected in the serum (sDSA) using single antigen bead, C1q, and C3d assays combined with the study of intragraft DSA (gDSA) in 86 patients who had DSA and underwent a kidney biopsy for cause (n = 58) or without evidence of kidney dysfunction (n = 28). DSA characteristics were collected and related to the presence of AMR, graft histological features, and allograft survival. Results Forty-five patients (52%) had C1q DSA, and 42 (51%) had C3d DSA. Allograft biopsies revealed AMR in 63 cases (73%), regardless of kidney function. gDSA were identified in 74% of biopsies. We observed a strong correlation among single antigen bead mean fluorescence intensity and complement assays positivity, presence of gDSA, and AMR occurrence. Conclusions Complement-binding DSA per se were not significantly associated with allograft survival in the entire study sample. Finally, gDSA predicted subsequent graft loss in patients who showed a stable renal function at the day of biopsy. Our data suggest that DSA mean fluorescence intensity and presence of gDSA might provide prognostic information during posttransplant monitoring.

Abstract: International audience; Graft-versus-host disease (GVHD) and cytomegalovirus (CMV)-related complications are leading causes of mortality after unrelated-donor hematopoietic cell transplantation (UD-HCT). The non-conventional MHC class I gene MICB, alike MICA, encodes a stress-induced polymorphic NKG2D ligand. However, unlike MICA, MICB interacts with the CMV-encoded UL16, which sequestrates MICB intracellularly, leading to immune evasion. Here, we retrospectively analyzed the impact of mismatches in MICB amino acid position 98 (MICB98), a key polymorphic residue involved in UL16 binding, in 943 UD-HCT pairs who were allele-matched at HLA-A, -B, -C, -DRB1, -DQB1 and MICA loci. HLA-DP typing was further available. MICB98 mismatches were significantly associated with an increased incidence of acute (grade II-IV: HR, 1.20; 95% CI, 1.15 to 1.24; P < 0.001; grade III-IV: HR, 2.28; 95% CI, 1.56 to 3.34; P < 0.001) and chronic GVHD (HR, 1.21; 95% CI, 1.10 to 1.33; P < 0.001). MICB98 matching significantly reduced the effect of CMV status on overall mortality from a hazard ratio of 1.77 to 1.16. MICB98 mismatches showed a GVHD-independent association with a higher incidence of CMV infection/reactivation (HR, 1.84; 95% CI, 1.34 to 2.51; P < 0.001). Hence selecting a MICB98-matched donor significantly reduces the GVHD incidence and lowers the impact of CMV status on overall survival.

Abstract: Graft-versus-host disease (GVHD) is among the most challenging complications in unrelated donor hematopoietic cell transplantation (HCT). The highly polymorphic MHC class I chain-related gene A, MICA, encodes a stress-induced glycoprotein expressed primarily on epithelia. MICA interacts with the invariant activating receptor NKG2D, expressed by cytotoxic lymphocytes, and is located in the MHC, next to HLA-B. Hence, MICA has the requisite attributes of a bona fide transplantation antigen. Using high-resolution sequence-based genotyping of MICA, we retrospectively analyzed the clinical effect of MICA mismatches in a multicenter cohort of 922 unrelated donor HLA-A, HLA-B, HLA-C, HLA-DRB1, and HLA-DQB1 10/10 allele-matched HCT pairs. Among the 922 pairs, 113 (12.3%) were mismatched in MICA. MICA mismatches were significantly associated with an increased incidence of grade III-IV acute GVHD (hazard ratio [HR], 1.83; 95% confidence interval [CI], 1.50-2.23; P < .001), chronic GVHD (HR, 1.50; 95% CI, 1.45-1.55; P < .001), and nonelapse mortality (HR, 1.35; 95% CI, 1.24-1.46; P < .001). The increased risk for GVHD was mirrored by a lower risk for relapse (HR, 0.50; 95% CI, 0.43-0.59; P < .001), indicating a possible graft-versus-leukemia effect. In conclusion, when possible, selecting a MICA-matched donor significantly influences key clinical outcomes of HCT in which a marked reduction of GVHD is paramount. The tight linkage disequilibrium between MICA and HLA-B renders identifying a MICA-matched donor readily feasible in clinical practice.

Abstract: International audience; Pancreatic islet grafting restores endogenous insulin production in type 1 diabetic patients, but long-term outcomes remain disappointing as a result of immunological destruction of allogeneic islets. In solid organ transplantation, donor-specific anti-HLA antibodies (DSA) are the first cause of organ failure. This retrospective multicentric study aimed at providing in-depth characterization of DSA response after pancreatic islet grafting, identifying the risk factor for DSA generation and determining the impact of DSA on graft function. Forty-two pancreatic islet graft recipients from the Groupe Rhin-Rhône-Alpes-Genève pour la Greffe d'Ilots de Langerhans consortium were enrolled. Pre- and postgrafting sera were screened for the presence of DSA and their ability to activate complement. Prevalence of DSA was 25% at 3 years postgrafting. The risk of sensitization increased steeply after immunosuppressive drug withdrawal. DSA repertoire diversity correlated with the number of HLA and eplet mismatches. DSA titer was significantly lower from that observed in solid organ transplantation. No detected DSA bound the complement fraction C3d. Finally, in contrast with solid organ transplantation, DSA did not seem to negatively affect pancreatic islet graft survival. This might be due to the low DSA titers, specific features of IgG limiting their ability to activate the complement and/or the lack of allogenic endothelial targets in pancreatic islet grafts.

Abstract: International audience; Background: The differential pathogenicity of anti-HLA donor-specific antibodies (DSAs) is not fully understood. The presence of complement-binding DSAs helps in better defining the prognosis of acute antibody-mediated rejection (ABMR). The evolution of these antibodies after the treatment of ABMR is unknown.Methods: We included patients from the French multicenter RITUX ERAH study diagnosed with acute ABMR within the first year of renal transplantation, with circulating anti-HLA DSAs and treated randomly by rituximab or placebo (and intravenous immunoglobulins, plasma exchange). We centrally analyzed serum samples at the time of ABMR, 3 and 6 months after ABMR, with anti-HLA DSAs specificities and C1q-binding capacity assessment.Results: Twenty-five patients were included: 68% had C1q-binding DSAs at the time of ABMR. The presence of C1q-binding DSAs was associated with a poorer evolution of chronic glomerulopathy at 6 months (P = 0.036). The persistence of C1q-binding DSAs at 3 and/or 6 months after ABMR was associated with more severe chronic glomerulopathy (P = 0.006), greater C4d score deposition score at 6 months after ABMR (P = 0.008), and graft loss 5 years after ABMR (P = 0.029). C1q-binding capacity was associated with the DSA MFI but 5 C1q-binding DSAs in 4 patients had low MFI values without a prozone effect.Conclusion: The presence and persistence of anti-HLA C1q-binding DSAs after ABMR is a detrimental marker, leading to transplant glomerulopathy and graft loss. Assessment of the complement-binding capacities of DSAs could help decide treatment intensification.

Abstract: International audience; Matching for HLA‐A, ‐B, ‐C, and ‐DRB1 loci (8/8 match) is currently the gold standard for unrelated donor hematopoietic cell transplantation (HCT). In Europe, patients are also matched at the HLA‐DQB1 loci (10/10 match). However, there is increasing evidence that matching at HLA‐DRB3/4/5 loci may help to lower transplant‐related morbidity and mortality. We therefore investigated the impact of HLA‐DRB3/4/5 mismatches on outcomes in 1975 patients who received a first 10/10 matched unrelated donor (MUD) HCT in France from 2000 to 2012 for a hematological malignancy. High‐resolution typing was performed at HLA‐A, ‐B, ‐C, ‐DRB1, ‐DQB1, ‐DPB1, and ‐DRB3/4/5 loci for all donor/recipient pairs. Compared with DRB3/4/5‐matched pairs, patients who received a MUD HCT from a DRB3/4/5 mismatched donor had a significantly increased risk of grade II‐IV acute graft‐versus‐host disease (aGVHD) (Adjusted Hazard Ratio (HR) 1.43 (1.07 to 1.90)) associated with lower graft‐versus‐host disease‐free and relapse‐free survival (GRFS) (Adjusted HR 1.20 (1.02 to 1.42)). Conversely, we observed no differences in terms of chronic GVHD, nonrelapse mortality, relapse and overall survival. However, we believe that patients stand to benefit from DRB3/4/5 loci being considered for unrelated donor selection to improve GRFS and then quality of life after unrelated HCT.

Abstract: Background: Graft-versus-host disease (GVHD) is a major cause of mortality after unrelated hematopoietic stem cell transplantations (HSCT). Despite the development of modern immunosuppressive strategies, a nearly perfectly controlled compatibility of the classical HLA genes (HLA-A, -B, -C, -DRB1, -DQB1, and -DPB1) and availability of numerous so-called minor histocompatibility antigens (e.g. HY or HA-1), its incidence remains largely unexplained to date. MIC genes (MHC class I chain-related) - a distinct lineage of MHC class I genes – are promising candidates to explain, at least partially, the incidence of GVHD in HLA-matched transplantations. MICA and MICB are highly polymorphic (100 alleles for MICA and 40 for MICB) and encode functional cell-surface glycoproteins up-regulated by cell stress. They interact with NKG2D, an activating receptor expressed on the surface of cytotoxic αβ CD8+ and γδ T lymphocytes and natural killer cells. MIC genes are already known to have a HLA-independent effect on solid graft outcomes and may play a similar role in HSCT by triggering GVHD. Objective: The objective of the present study was to determine the impact of donor/patient matching at the MICA and MICB loci on the incidence of GVHD in patients undergoing unrelated HSCT. Methods: We retrospectively analyzed a multicenter cohort of 1072 unrelated transplantations performed between 1996 and 2013. All donor-recipient pairs were fully typed at high resolution for HLA-A, -B, -C, -DRB1, -DQB1, and -DPB1 and were matched for ten of ten HLA alleles (HLA 10/10 matched). High resolution genotyping of MICA and MICB was performed by sequenced-based typing in order to define matching grades between donors and patients. The endpoints of the study were acute and chronic GVHD. Apart from HLA-DPB1 matching, statistical models were adjusted for major clinical variables which have been shown to be associated with outcome (patient’s age, patient’s and donor’s sex, patient’s and donor’s serological status for cytomegalovirus, year of transplantation, time to transplantation, transplantation center, source of stem cells, conditioning regimen, GVHD prophylaxis, treatment with anti-thymocyte globulin, disease category and severity at transplantation). Results: Of the 1072 transplantations, 134 (12.5 %) and 380 (35.4 %) were mismatched at the MICA and MICB locus, respectively. Both MICA and MICB mismatches were significantly associated with an increased incidence of severe acute GVHD (grades III-IV) in univariate and multivariate models (multivariate model: HR = 2.32, 95 % CI = 1.84-2.92; p=0.0003 for MICA and HR = 1.49, 95 % CI = 1.24-1.79; p=0.03 for MICB). At day 100 post-HSCT severe acute GVHD incidences in mismatched vs. matched transplantations were 19.62 % vs. 15.08 % and 20.00 % vs. 14.84 % for MICA and MICB, respectively (Figure 1). Chronic GVHD was associated with MICA and MICB mismatches in univariate analysis (HR = 1.55, 95 % CI = 1.27-1.89; p=0.029 for MICA and HR=1.38, 95 % CI = 1.19-1.62; p=0.03 for MICB), but showed only a trend for association in multivariate models. Figure 1 Estimated cumulative incidence curves of grades III–IV acute GVHD according to MICA (panel A) and MICB (panel B) matching status. The solid and dashed lines represent MIC matched and mismatched grafts, respectively. The Fine and Gray model was used with relapse and death considered as competing risks. Figure 1.

Conclusion: To date this is the largest reported MICA and MICB sequence analysis whether in HSCT or solid organ transplantation. Inclusion of MICA and MICB typing in the donor selection process may be a practical clinical strategy for lowering the risks of severe acute GVHD after unrelated HSCT.

Abstract: Donor-specific antibodies (DSA) increase the risk of allograft rejection and graft failure. They may be present before transplant or develop de novo after transplantation. Here, we studied the evolution of preformed DSA and their impact on graft outcome in kidney transplant recipients. Using the Luminex Single Antigen assay, we analyzed the sera on the day of transplantation of 239 patients who received a kidney transplant. Thirty-seven patients (15.5%) had pre-existing DSA detected the day of transplantation. After 5 years, the pre-existing DSA disappeared in 22 patients whereas they persisted in 12. Variables associated with DSA persistence were age50 years (P = 0.009), a history of previous transplantation (P = 0.039), the presence of class II DSA (P = 0.009), an MFI of preformed DSA3500 (P 0.001), and the presence of two or more DSA (P 0.001). DSA persistence was associated with a higher risk of graft loss and antibody-mediated rejection. Previously undetected preformed DSA are deleterious to graft survival only when they persist after transplantation.

11. Survenue d’une thrombopénie sévère et durable, au décours d’une greffe de moelle allogénique, imputable à l’existence chez l’hôte d’une allo-immunisation anti-HPA-1

Abstract: A 56 year-old, multiparous woman suffering from a myeloproliferative syndrome, who had received multiple red blood cell and platelet transfusions, was the recipient of an allograft of peripheral blood stem cells derived from her HLA-A, B, DR, DQ and DP and ABO identical sister, following myeloablative conditioning. The persistence of severe, isolated thrombopenia resistant to platelet transfusions led to the discovery of anti-HLA class I allo-immunisation. As HLA compatible platelet transfusions did not result in satisfactory platelet increments, we then discovered the simultaneous presence of anti-HPA-1a allo-immunisation. Genotyping of the HPA-1 systems of the patient (HPA-1B/B) and her sister (HPA-1A/B) enabled us to elucidate the mechanism underlying the persistent thrombopenia and the inefficacy of transfusion. In fact, only transfusion of HPA-1B/B platelets (HLA compatible or incompatible) proved to be efficacious. To reduce the level of anti-HPA-1a antibodies, we performed plasmapheresis sessions and used an anti-CD20 monoclonal antibody. It was only on achieving total haematopoietic chimerism, through rapid interruption of the immunosuppression, that we obtained spontaneous normalisation of the platelet count. The present case emphasises the necessity, before undertaking any allograft of haematopoietic stem cells - even if the latter come from a strictly HLA identical member of the family - of performing a search for eventual anti-HPA allo-immunisation.

Abstract: Background Posttransplant lymphoproliferative disorders (PTLD) occur in 0.5% to 2.5% of cases in renal-transplant recipients. Epstein-Barr virus (EBV) is usually detected in the tumor cells, suggesting a role for this virus as an agent of B-cell proliferation. It is unusual for patients receiving allografts from the same donor to develop PTLD simultaneously. Methods we describe two patients who received renal allografts from the same donor and developed PTLD simultaneously. The presence of EBV in both tumors was confirmed. In this report, the origin of tumor cells was determined by immunohistochemical human leukocyte antigen (HLA) typing and microsatellite analysis. Clonality was studied by immunoglobulin gene rearrangement analysis. Results Our results suggest that the tumor originated from donor cells in both patients but, because immunoglobulin gene rearrangements were different, this could mean that lymphoid cells proliferate independently in each recipient. Conclusions We propose the following pathogenesis: immortalization of passenger B lymphocytes by EBV, proliferation of these cells, and development of PTLD by means of immunosuppression, antigenic stimulation, and HLA mismatch.

Abstract: We describe the decline in islet function, in relation to HLA sensitization, in an islet transplant recipient and the recovery of this function after treatment with anti-CD20 monoclonal antibody and IV immunoglobulins. A 51-year-old woman with type 1 diabetes received one intraportal islet infusion. Following this transplantation, she became insulin independent. A search for HLA antibodies by using an ELISA technique remained consistently negative for HLA class I and II. It was only 2 years after the islet transplantation that this search became positive against class II antigens, reaching a peak of reactivity concomitantly with the appearance of a deterioration of glucose control requiring low-dose insulin therapy. Luminex® screening and single-antigen assays then revealed the presence of both nondonor-specific and donor-specific antibodies against HLA class II molecules. This immunization, already present in the pretransplant serum, had increased during the 6 months preceding the clinical deterioration. Since these data nevertheless pointed to antibody-mediated rejection of the islet allograft, treatment with anti-CD20 monoclonal antibody and IV immunoglobulins was initiated. One month later, the search by ELISA for antibodies against HLA class II antigens became negative, the Luminex® tests normalizing more gradually. As the result of an improvement in glucose control, the patient was again insulin-free.

Abstract: Congenital HLA class I deficiency is a rare disease frequently resulting in chronic inflammation of the respiratory tract, and/or skin granulomas.1,2 The deficiency may be unnoticed for decades, so pathological outcome is relatively unpredictable.3 We here describe a 14 year old patient with a severe ocular toxoplasmosis who is HLA class I deficient, as a result of a homozygous mutation in the gene encoding one of the two subunits of the peptide transporter associated with antigen processing (TAP). We propose that such a defect should be investigated in patients with severe ocular toxoplasmosis without acquired immunodeficiency. At the time of referral, the patient did not have any particular medical history except an exaggerated reaction to an intradermal tuberculin test 1 year earlier. His right eye displayed a strong reduction of acuity with anterior and posterior inflammatory lesions and pain. There was corneal inflammation with flare in the anterior chamber, anterior uveitis with cellular deposits on the corneal endothelium (keratic precipitates) but without posterior synechiae and grade B3 vitritis. …
