Positive Impact of Chronic Graft-Versus Host Disease on Survival in 928 Allogeneic Hematopoietic Stem Cell Transplant Recipients

Abstract Introduction: Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is a standard curative treatment option in hematological diseases. The anti-leukemic activity relies not only the effects of conditioning regimen but also the immune mediated graft-versus leukemia (GVL) effect. Donor T cells are responsible for the GVL and causes complications namely acute and chronic graft versus host disease (GVHD). Herein, we aim to present the relation of graft versus host disease with survival and relapse. Patients and Methods: We retrospectively evaluated 928 Allo-HSCT between 1989 and 2015 followed in our institution. Chi-square test and student's t test were used in comparison. P <0.05 was considered statistically significant. Results: 551 patients were male (59%) and 377 patients (41%) were female. The median age of the group was 34 (range 15 -71). Patients received stem cell from related donors more frequently (85%) with HLA full match (66%). Peripheral blood was the source of stem cells in 645 recipient (70%) followed by bone marrow (28%). 75 patients were diagnosed as benign hematological disorders. The most common malign hematological diagnosis was acute myeloid leukemia in 366 patients (39%). Patients received 80% of myeloablative conditioning regimen prior to transplantation. 43% of the patients diagnosed as acute GVHD and 45% had chronic GVHD. 798 achieved engraftment (86%) neutrophil engraftment median of 16 days, platelet engraftment median of 14 days. Relapse was detected in 6% of patients. The overall survival (OS) was 59 months and progression free survival (PFS) was 33 months. Acute GVHD had no impact on OS, PFS, relapse rate. The OS in patients with chronic GVHD was significantly higher than in GVHD negative patients (68.8 vs 56.9, P=0.009). Although chronic GVHD patients had lower risk of relapse and higher PFS, the results were not statistically significant. Conclusion: GVHD is a serious complication and important cause of post transplant morbidity. Chronic GVHD is associated with lower risk of relapse in previous studies. In this study, we have concluded the improved OS in patients with chronic GVHD. The immune mediated GVL effect may be the reason for anti-leukemia effect and improved survival.

Graft versus host disease is one of the main complications of Hematopoietic stem cell, involving about 50% to 80% of the patients. Acute GVHD clinical manifestations and therapy is discussed, as well as new NIH criteria for the diagnosis and classification of chronic GVHD. Therapy for both refractory chronic and acute GVHD is an important field of discussion once there is no superiority for the majority of the agents after primary therapy has failed. Hence, this review is meant to be a useful tool of consultation for clinicians who are dealing with this complex complication.

Abstract Introduction: EBV seropositivity in general population is 80%. Reactivation of latent infection in pre-transplant seropositive patients causes post-transplant lenfoproliferative disease (PTLD) following Allo-HSCT. The effect of donor EBV positivity on recipient's risk of graft versus host disease is not clear. Our aim is to present EBV seroprevalence and PTLD incidence as well as demonstrating the relation of EBV seropositivity with GVHD. Patients and Methods: A total of 364 allogeneic stem cell transplant recipients and donors were evaluated retrospectively from 2006 to 2015. During Allo-HSCT preparation procedures all recipients and donors were serologically tested. EBV specific IgG (VCA-IgG, EBNAIgG, EA-IgG) and IgM (VCA-IgM) antibodies were determined by Chemiluminescence by ARCHITECT lab analyzers using commercially available kits (Abbott, USA). All patients were followed for reactivation. Results: EBV IgG positivity was detected in 338 of recipients (92.8%) and 283 of donors (77.7%). There was no statistically difference detected between related or unrelated transplants. The mean age was 37 (range 16-67). 217 recipients were male (60%). 295 (81%) patients were transplanted for malign hematological diseases. The majority of patients were grafted from full-matched related donors (258, 71%). The most common source of stem cell was peripheral blood in 299 patients (82%) followed by bone-marrow in 56 patients (15%), bone-marrow plus peripheral blood in 9 patients (3%). 273 (75%) patients received myeloablative conditioning regimen. All patients received prophylactic acyclovir (in related transplants 400mg 3 times daily, in un-related transplants 800mg 3 times daily) starting from conditioning and up to three months posttranplant period. One pretransplant seropositive 26 year-old aplastic anemia patient had PTLD with EBV IgM positivity within 3 months posttransplant. He received 4 cycles of rituximab and prednisolone and achieved complete response. Three patients had EBV IgM positivity in posttransplant 4, 9 and 24th months with symptoms of infectious mononucleosis. The seropositivity resolved without treatment. Acute GVHD developed in 223 patients (61%) whereas chronic GVHD was detected in 285 (78%) of patients. The incidence of acute GVHD was similar when donor was EBV seropositive compared to seronegative (78% vs 22%, p=0.72). Chronic GVHD incidence was similar between donor EBV seropositive group compared to seronegative group (80% vs 20%, P=0.199). Conclusion: EBV seropositivity is common detected in 92.8% of our allo-HSCT recipient cohort. Donor EBV status did not have an effect on developing acute or chronic GVHD.

CONTEXT AND OBJECTIVE: Graft-versus-host disease (GVHD) is one of the complications following allogenic stem cell transplantation. This study investigated an association between human leukocyte antigen (HLA) and the occurrence of acute and chronic GVHD in patients who had received stem cell transplantations from HLA-identical siblings. DESIGN AND SETTING: Retrospective study at Hematology and Hemotherapy Center, Universidade Estadual de Campinas (Unicamp). METHODS: The participants were 176 patients whose first transplant was between 1997 and 2009. HLA genotyping was performed serologically and using the polymerase chain reaction with specific primer sequence. RESULTS: Acute GVHD was positively associated with HLA-A10 (P = 0.0007), HLA-A26 (P = 0.002), B55 (P = 0.001), DRB1*15 (P = 0.0211) and DQB1*05 (P = 0.038), while HLA-B16 (P = 0.0333) was more frequent in patients without acute GVHD. Chronic GVHD was positively associated with HLA-A9 (P = 0.01) and A23 (P = 0.0292) and negatively with HLA-A2 (P = 0.0031) and B53 (P = 0.0116). HLA-B35 (P = 0.0373), B49 (P = 0.0155) and B55 (P = 0.0024) were higher in patients with acute GVHD grade 3 or above, than in other patients. In patients with extensive chronic GVHD, HLA-A9 (P = 0.0004), A24 (P = 0.0059) and A26 (P = 0.0411) were higher than in other patients, while HLA-A2 was lower (P = 0.0097). CONCLUSION: This study suggests that HLA can influence the incidence and severity of acute and chronic GVHD. However, a study with a better design and more patients will be needed to confirm these results.

Cytokine Activation

Abstract Abstract 2221 Poster Board II-198 Background: Acute graft-versus-host disease (GVHD) was known to be involved in the Th1 cytokine activation and alloreactive T-cell cytotoxicity, while the pathogenesis of chronic GVHD is yet revealed fully although in which Th2 cytokine activation or transforming growth factor (TGF) mediated pathway was suggested to be involved. The current study is a hypothesis generating study in order to identify potential predictive surrogate associated with the risk of acute or chronic GVHD in addition with transplant outcomes after allogeneic hematopoietic stem cell transplantation (HSCT). Methods: The current study was performed to identify genetic surrogates predicting the risk of acute / chronic GVHD, relapse free survival, non-relapse mortality and overall survival in 394 pairs transplanted at the Princess Margaret Hospital, Toronto, ON, Canada. In addition, the predictive markers for organ specific incidence of acute / chronic GVHD were also evaluated (i.e. for skin/liver/gut acute GVHD or skin, eye, oral, lung or liver chronic GVHD). Total of 261 single nucleotide polymorphisms (SNPs) in 56 genes were determined for donor/recipients' genotypes using MALDI-TOF based platform, involving in the pathways of 1) cytokines (i.e. IL1A, IL1B and its receptor, IL1R1, IL2 & IL2RA, IL4 & IL4R, IL6 & IL6R, IL8, IL10 & IL10RA, RB, IL12A/BandIL12RB1, IFNG & IFNGR1/2, TNFTI/II/II), 2) NFKB (NFKB1/2/A, NFKBIA/B, IKB, IKK1, IKBKB, RelB), 3) apoptosis (FAS, TRAIL & TRAILR1), 4) endothelium nitric oxide regulation (EDN1, NOS1/2A/3), 5) PDGF (PDGFB/C/D & PDGFRA/B), 6) TGF-β (TGFB1/2 & TGFBR1/2/3, TGFRB1), 7) Toll-like receptor (TLR4/5), 8) NOD2/CARD15 and 9) prostaglandin-endoperoxide synthase (PTGS1/2). The candidate genotypes have been selected by choosing the SNPs in non-synonymous SNPs in exon region with minor allele frequency of > 0.05 to 0.1. Results: Followings are the lists of recipients' and donors' genotypes with p-value<0.05 thus associating with clinical outcomes following allogeneic HSCT: In summary, the risk of chronic GVHD was significantly associated with SNP of the genes involved in the pathway of NFKB, PDGF, TGF-β, and some of cytokines (esp. type II, IL6 & IL4), while that of acute GVHD associates with the genotypes in the pathway of TNF and apoptosis. In addition, survival after allogeneic transplantation was associated with the genotypes in NOS (nitric oxide synthase, endothelial nitric oxide synthesis pathway), IL-2 and TGF pathway. Conclusion: Because of complex nature of GVHD pathogenesis, multiple candidate pathway SNPs has been explored targeting SNPs in the pathway of cytokines, NFKB, apoptosis, endothelium nitric oxide regulation, NOD2/CARD15, PDGF, PTGS1/2, TGF-β and TLR. Different involvements were noted of TGF-β, PDGF or NFKB with chronic GVHD versus TNF and apoptosis-associated SNPs with acute GVHD. Further study will help us to reach more clear conclusion which genotype is the predictor of the risk of GVHD. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 4534 Auto/alloimmune hepatitis (AIH) is an inflammatory liver disease characterized histological by a dense mononuclear cell infiltrate in the portal tract and serological by the presence of non-organ and liver-specific antibodies, high transaminases and increased levels of IgG. The relation between allogeneic hematopoietic stem cell transplantation (HSCT) and auto/alloimmune disease is complex. To examine this association, we retrospectively studied 1,636 allogeneic patients (median age 43, range 18–73 years) between May 1996 and December 2008. Among these patients, 311 (19%) developed hepatic graft-versus-host disease (GvHD) (162 pts had a hepatic GvHD of grade > II). We followed 25 patients (11 male, 14 female) in whom GvHD of the liver presented with marked elevation of serum aminotransferases, clinically resembling acute hepatitis and auto/antibodies characteristics for AIH. The median age at transplant was 35 (range, 18–54) years. Onset of liver dysfunction was at 286 days (range, 55–2766) after HSCT. Median peak serum was 312 (range 105–1750) U/L for alanine aminotransferase, 629 (133-2410) U/L for gamma-glutamyl transferase and 1.74 (0.5-23.4) mg/dl for bilirubin. The autoantibody profiles of AIH were 60% for anti-nuclear antibody, 44% for antibodies to liver-kidney microsomes, 24% for antibodies to smooth-muscle antigens, 28% for anti-mitochondrial antibody, 16% for antibodies to actin, 8% for antibodies to nucleoli, and 4% for other autoantibodies. AIH had a higher prevalence in younger and in female patients. AIH occurred in 92% in patients, who were transplanted with G-CSF mobilized and peripherally collected stem cells (PSC), but in only 8% in patients with bone marrow (BM) source (p<0.02), comparing all transplanted patients (1326 PSC, 310 BM). Stem cell grafts from matched sibling donor or matched unrelated donor were similar in the two groups. Acute GvHD of grade> II occurred more frequently in the groups with AIH (15/25 vs. 649/1636, p<0.002), and chronic GvHD (11 limited, 14 extensive) was ascertained in all AIH patients vs. 49.8% in all transplanted patients (p<0.0001). Three patients with AIH died from pulmonary bleeding, chronic GvHD, and relapse, whereas 22 patients with AIH are still alive (88%) at a median survival time of 2570 days. In conclusion, our evaluation confirms a strong association between G-CSF mobilized PSC, chronic GvHD and the development of AIH. Disclosures: No relevant conflicts of interest to declare.

Abstract Calcineurin inhibitors form the backbone of graft versus host disease (GVHD) prophylaxis in hematopoietic stem cell transplantation. In the adult literature tacrolimus was demonstrated superior to cyclosporine in preventing grade II–IV acute GVHD in both related and unrelated donor transplants; however, there is no data comparing their efficacy in the pediatric population. In a multi-institutional trial, we prospectively evaluated the clinical data on 102 patients receiving either cyclosporine/methotrexate or tacrolimus/methotrexate based prophylactic regimens for 6/6 matched unrelated donor, transplant. Conditioning regimens were fully ablative; no T-cell depletion was permitted; cord blood donors were excluded. Patients were required to receive either cyclosporine or tacrolimus, but the choice was per investigator preference. The two arms were reasonably balanced: 59.8% of patients received cyclosporine and 40.2% of patients received tacrolimus. Rates for maximum grade II–IV acute GVHD were 37.7% for cyclosporine and 39% for tacrolimus (p = 0.89). Rates for maximum grade III–IV acute GVHD were 19.6% for cyclosporine and 24.4% for tacrolimus (p = 0.57). Incidence of chronic GVHD in 97 evaluable patients was 37.9% in 58 patients who received cyclosporine and 35.8% in 39 patients who received tacrolimus (p = 0.84). Survival at 1 year post-transplant was similar in both groups: 59.2% for cyclosporine and 51.2% for tacrolimus (p= 0.31). Toxicity analysis is ongoing. In pediatric matched unrelated donor transplantation, the efficacy of tacrolimus/methotrexate and cyclosporine/methotrexate based regimens for prophylaxis of GVHD are not significantly different.

Abstract Beyond disease biology, the success of allogeneic hematopoietic stem cell transplantation (HSCT) in patients with hematological malignancies is mainly determined by the occurrence and extent of graft versus host disease (GVHD). Therefore, prevention of GVHD is the major goal and challenge in clinical HSCT. A calcineurin-inhibitor combined with methotrexate is the standard graft versus host disease (GVHD) prophylaxis after allogeneic hematopoietic stem cell transplantation (HSCT). Everolimus is a derivative of sirolimus, which also seems to mediate anti-leukemia effects. Given the potential synergism and favourable toxicity profile of everolimus and tacrolimus (EVTAC) after allogeneic HSCT we sought to investigate the efficacy of this combination in patients with either myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML). We report a combination of everolimus (days 0–56) and Tacrolimus (from day −1 on) in 24 patients (pts, median age 62 years) with either MDS (n=17) or AML (n=7) undergoing intensive busulfan-based conditioning followed by HSCT from related (n=4) or unrelated matched (n=12) or 1-allele mismatched (n=8) donors. All pts engrafted and only one experienced grade IV mucositis. However, although everolimus was scheduled to be administered up to day 56, patients received the drug a median of 44 days (range 10–56) only. The reason for premature discontinuation (50%) were either occurrence of early-onset (day 6) GVHD associated hyperbilirubinemia CTC grade 4 (n=1), transplantation-associated microangiopathy (TMA, n=3), sinusoidal obstructive syndrome (SOS) of the liver (n=6) or a drop of platelets after engraftment by at least 50% (n=2). Nine pts (37%) developed grade II–IV acute GVHD, however, chronic extensive GVHD was observed in 11 of 17 (64%) evaluable pts. TMA occurred in 7 pts (29%) with two cases of acute renal failure. In five out of seven patients with TMA either tacrolimus (n=4) or everolimus (n=1) blood through levels were slightly above the upper target level at the time of TMA appearance. The study was terminated prematurely because additional 6 pts (25%) developed SOS, which was fatal in two cases. With a median follow-up of 26 months, the 2-year overall survival rate is 47%. In conclusion, although this new combination appears to be effective as prophylactic regimen for acute GVHD, the incidence of TMA and SOS seems to be higher compared to other regimens. As a result this combination cannot be recommended as prophylactic regimen after busulfan-based intensive conditioning. However, studies in the context of TBI-based or reduced-intensity conditioning regimens might come to a different conclusion.

Abstract Although the effects of human leukocyte antigen (HLA) locus matching on clinical outcome in unrelated hematopoietic stem cell transplantations have been characterized, the biologic implications of HLA haplotypes have not been defined. We demonstrated the genetic fixity of Japanese conserved extended haplotypes by multi–single nucleotide polymorphism analysis in 1810 Japanese donor-recipient pairs matching with HLA-A, -B, -C, -DRB1, and -DQB1 alleles. Three major Japanese conserved extended haplotypes (named HP-P1, HP-P2, and HP-P3) were essentially completely conserved at least in the 3.3-Mb HLA region from HLA-A to -DPB1, and extended far beyond HLA-A. The risk of acute graft-versus-host disease (GVHD) of these HLA haplotypes was assessed with multivariate Cox regression in 712 patients transplanted from HLA fully (HLA-A, B, C, DRB1, DQB1, and DPB1) matched unrelated donors. HP-P2 itself reduced the risk of grade 2 to 4 acute GVHD (hazard ratio [HR] = 0.63; P = .032 compared with HP-P2-negative), whereas HP-P3 tended to increase the risk (HR = 1.38; P = .07). Among 381 patients with HP-P1, HP-P1/P3 (HR = 3.35; P = .024) significantly increased the risk of acute GVHD compared with homozygous HP-P1. This study is the first to demonstrate that a genetic difference derived from HLA haplotype itself is associated with acute GVHD in allogeneic hematopoietic stem cell transplantation.

Graft Versus Host

Chronic graft versus host disease (GVHD) is a significant cause of morbidity and mortality in matched unrelated donor hematopoietic stem cell transplantation. Incidence of acute GVHD is a major risk factor for chronic GVHD. Calcineurin inhibitors form the backbone of graft versus host disease (GVHD) prophylaxis in hematopoietic stem cell transplantation. When comparing cyclosporine to tacrolimus for GVHD prophylaxis, we previously reported a trend toward superiority of cyclosporine as prophylaxis against acute GVHD. We now analyze their effect on the incidence and severity of chronic GVHD. In a multi-institutional trial, we prospectively collected the clinical data on 141 evaluable patients receiving either cyclosporine/methotrexate or tacrolimus/methotrexate based prophylactic regimens for 6/6 matched unrelated donor, transplant. Conditioning regimens were fully ablative; no T-cell depletion was permitted; cord blood donors were excluded. Patients were required to receive either cyclosporine or tacrolimus, but the choice was per investigator preference. The two arms were reasonably balanced: 60.1% of patients received cyclosporine and 39.9% of patients received tacrolimus. Rates for acute GVHD were 60.4% for cyclosporine and 73.8% for tacrolimus (p = 0.086). Rates for chronic GVHD were 44.2% for cyclosporine and 47.3% for tacrolimus (p = 0.7). In the 61 patients with chronic GVHD, extensive disease was present in 82.9% of cyclosporine group and 80.8% of the tacrolimus group (p = 1.0) Those graded as moderate or severe comprised 80% of the cyclosporine group and 56% of the tacrolimus group (p = 0.46) and those both extensive and moderate or severe were 71.4% and 52%, respectively (p = 0.12). In pediatric matched unrelated donor transplantation, the incidence and severity of chronic graft versus host disease in patients receiving either tacrolimus/methotrexate or cyclosporine/methotrexate based regimens for prophylaxis of GVHD are not significantly different.

Cytokine Gene Polymorphisms

Abstract Abstract 4180 Graft-versus-host disease (GvHD) is one of the most important complications after allogeneic hematopoietic stem cell transplantation (HSCT) and influences morbidity and mortality, even when the donor is a human leucocyte antigen (HLA)-matched sibling. Polymorphisms at genes coding for several proinflammatorycytokines and for their related receptors or receptor inhibitors are involved in this complication. To assess the role of cytokine gene polymorphisms on acute GvHD (aGVHD), we analysed 189 pairs of donor and recipients transplanted from HLA identical sibling for malignant hematological diseases between 2000 and 2007, using a non T depleted graft after a myeloablativeor a reduced intensity conditioning regimen. Material and methods: The median age of the recipients at transplantation was 43.4 years (1–68). Two third of the patients received bone marrow before myelo-ablative conditioning regimen and the median delay between diagnosis and transplantation was 9 months (1–76). Five different polymorphisms from 3 cytokine genes were analyzed: IL-10 –592C/A, -819C/T and -1082G/A, IL-1b -511A/G and TGFb1 –509C/T. All the pairs were studied for each gene polymorphism using the Taqman technology as previously described (Malkki2007). Each kit contains several primers pairs for amplification and two allele-specific probes, each of them conjugated with a different fluorescent marker. After amplification, analysis was driven on a Roche LC480 platform. The interpretation of the final results was performed using allelic discrimination specific software. In our study, the frequencies of the TGFb1, IL1b, and IL-10 genotypes in recipients and donors were almost equal, and were consistent with previously reported results for the Caucasoid population and with the NCBI SNP databases. Results: Univariate analysis found a significant negative impact of donor genotypes carrying IL1b A allele (p=0,02) or IL10–592 A allele (p=0,03) on aGvHD. We did not find any effect associated with IL10–819 and -1082 polymorphisms, but as previously described (Lin 2003), the presence of IL10 A-T-A haplotype in the donor, significantly increased the risk of aGVHD (p=0.043). We performed a multivariate analysis on aGVHD incidence taking into account TGFb1–509, IL-10–592 and IL1bpolymorphisms, together with other known risk factors. A higher incidence of aGVHD was found in pairs where donor has an IL1b A allele (HR 4,16 - p=0,0031) and increased when the donor is A/A (HR>15 – p=0,0091). For IL10–592, the impact of the A allele was found different when carried by the donor (higher risk of aGVHD, HR 3,52 – p=0,00083) or the recipient (lower risk of aGVHD, HR 0,48 – p=0,024), but this effect seems only significant in pairs where donor did not carry any A allele (rec AC × don CC – HR 0.2 – p=0.05). Donor with TGFb1–509 T allele was found to have a significant lower risk of aGVHD (HR 0,42 – p=0,02). (table 1). The role of the cytokine cascade in the physiopathology of GVHD is well established. Our study documents the possible role of IL-1b, TGFb1and IL10 gene polymorphisms in this setting. A proven association of cytokine gene polymorphisms with acute GVHD would enable the clinician to modify the therapeutic strategy and enhance the outcomes.
