Acute Graft

Acute graft versus host disease (aGvHD) is an important, life-threatening complication after allogeneic hematopoietic stem cell transplantation (alloHSCT). To investigate the value of multiple simultaneous colon biopsies in improving diagnostic accuracy in patients with aGvHD, we retrospectively analyzed 157 patients after alloHSCT. The biopsies were evaluated individually using three established histological grading systems (Lerner, Sale, and Melson). The maximum, minimum, median, and mean histological aGvHD grades were calculated for each patient, and the results were correlated with the Glucksberg grade of clinical manifestation of GvHD, steroid therapy status, and outcome. We found that multiple colon biopsies enhanced diagnostic sensitivity. Moreover, higher histological grades correlated with steroid therapy initiation and refractoriness; the latter particularly occurred when advanced damage was present in all samples and healthy colon mucosa was reduced or absent. On multivariate analysis, the minimal Lerner and Glucksberg grades for intestinal aGvHD were significantly associated with steroid treatment failure. Ninety-nine patients died. The median survival was 285 days after the biopsies were taken. Fifteen patients died from relapse of their underling disorder and 84 from other causes, mostly infection (53 patients) and GvHD (14 patients). Multivariate analysis revealed a significant association between none-relapse mortality and the mean Lerner grade, minimum Melson grade, Glucksberg organ stage, and platelet counts. Thus, we found the Lerner system to be superior to the other grading methods in most instances and histologic evaluation of multiple simultaneously obtained biopsies from the colon to result in a higher diagnostic yield, which helps plan systemic steroid treatment while predicting treatment response and outcome.

Acute Graft

Acute graft versus host disease (aGVHD) remains a leading cause of morbidity and mortality in allogeneic hematopoietic stem cell transplant (allo-HSCT). Tacrolimus (TAC), a calcineurin inhibitor that prevents T-cell activation, is commonly used as a GVHD prophylaxis. However, there is variability in the serum concentrations of TAC, and little is known on the impact of early TAC levels on aGVHD. We retrospectively analyzed 673 consecutive patients undergoing allo-HSCT at the Ohio State University between 2002 and 2016. Week 1 TAC was associated with a lower risk of aGVHD II–IV at TAC level ≥10.15 ng/mL (p = 0.03) compared to the lowest quartile. The cumulative incidence of relapse at 1, 3 and 5 years was 33%, 38% and 41%, respectively. TAC levels at week 2, ≥11.55 ng/mL, were associated with an increased risk of relapse (p = 0.01) compared to the lowest quartile. Subset analysis with acute myeloid leukemia and myelodysplastic syndrome patients showed significantly reduced aGVHD with TAC level ≥10.15 ng/mL at week 1 and a higher risk of relapse associated with week 2 TAC level ≥11.55 ng/mL (p = 0.02). Hence, achieving ≥10 ng/mL during the first week of HCT may mitigate the risk of aGVHD. However, levels (>11 ng/mL) beyond the first week may be associated with suppressed graft versus tumor effect and higher relapse.

Abstract Background Cytomegalovirus (CMV) is a serious complication following Hematopoietic Stem Cell Transplant (HSCT) and can lead to serious organ disease and mortality. This study aimed to investigate the association between absolute lymphocyte count (ALC) and CMV to determine whether ALC could help to identify those at an increased risk of CMV infection and recurrence Methods Adults undergoing HSCT between 2011 and 2016 at Rigshospitalet, Denmark were included. Cox proportional hazards models investigated risk factors, including ALC, for CMV infection in the first year post-transplant and recurrent CMV infection 6 months after clearance and stopping CMV treatment for the first infection. For the primary outcome ALC was investigated as a time-updated risk factor lagged by 7 days, and for recurrent CMV, ALC measured at the time at the time of stopping treatment for the first CMV infection was investigated (+/- 7 days). Results Of the 352 HSCT recipients included, 57% were male, 40% received myeloablative conditioning, 42% had high risk (D-R+) CMV IgG serostatus at transplant and the median age was 56 (IQR 43-63). 143 (40.6%) patients had an episode of CMV DNAemia a median of 47 days after transplant (IQR 35-62). A lower current ALC (≤ 0.3 x109/L) was associated with a higher risk of CMV infection in univariate analysis compared to a high current ALC (> 1 x109/L). However, this association was attenuated after adjustment, particularly for acute graft versus host disease (Figure). 102 HSCT recipients were investigated for risk of recurrent CMV of which 41 (40.2%) had a recurrent CMV episode a median of 27 days (IQR 16-50) after stopping CMV treatment for the first infection. A lower ALC (≤ 0.3 x109/L) at the time of stopping CMV treatment was associated with a significantly higher risk of recurrent CMV after adjustment (Figure). A higher peak viral load (> 1500 IU/ml) during the first episode of CMV infection was also associated with an increased risk of recurrent CMV (aHR 2.47, 95%CI 1.00-6.10 compared to < 750 IU/ml). Association between absolute lymphocyte count (ALC) and risk of CMV infection and recurrent CMV within 6 months. **First CMV infection multivariable model also adjusted for sex, CMV serostatus, age, year of transplant, Charlson Comorbidity Index, Anti-thymocyte globulin (ATG) given, HLA donor-recipient matching, and acute graft versus host disease (time-updated) *Recurrent CMV infection multivariable model also adjusted for conditioning regimen, sex, CMV serostatus, age, year of transplant Anti-thymocyte globulin (ATG) given, HLA donor-recipient matching, and acute graft versus host disease and peak CMV viral load during the first CMV infection Conclusion A lower ALC at the time of stopping treatment for the first CMV infection was associated with an increased risk of recurrent CMV and could be used to help guide decisions for augmented CMV surveillance and clinical awareness of CMV disease symptoms in these patients.

AbstractAcute graft-versus-host disease (aGvHD), post-allogeneic hematopoietic stem cell transplantation, is associated with high mortality rates in patients not responding to standard line care with steroids. Adoptive mesenchymal stromal cell (MSC) therapy has been established in some countries as a second-line treatment.Limitations in our understanding as to MSC mode of action and what segregates patient responders from non-responders to MSC therapy remain. The principal aim of this study was to evaluate the immune cell profile in gut biopsies of patients diagnosed with aGvHD and establish differences in baseline cellular composition between responders and non-responders to subsequent MSC therapy.Our findings indicate that a pro-inflammatory immune profile within the gut at the point of MSC treatment may impede their therapeutic potential. These findings support the need for further validation in a larger cohort of patients and the development of improved biomarkers in predicting responsiveness to MSC therapy.

e19027 Background: Clostridiodes difficile infection (CDI) is reported to occur up to 9-fold higher in allogenic hematopoietic stem cell transplant (HSCT) recipients compared to the general population of hospitalized patients. This is attributed to disruption of gut microbiome by antibiotics, myeloablative regimens, neutropenia, prolonged hospitalization, and immunosuppressive regimens administered to prevent acute graft-versus-host disease (aGVHD). CDI by disruption of the intestinal microbiome may trigger gastrointestinal aGVHD. Previous studies from HSCT centers have reported conflicting data on the relationship between CDI and subsequent development of aGVHD. Methods: The Nationwide Readmissions Database was queried for admissions of adult allogenic HSCT patients between 2016 and 2018. Those with and without CDI during index admission were compared. Multivariable logistic regression was used to evaluate the primary outcome of risk of aGVHD in the index admission or within 100 days post-engraftment. Results: A total of 13518 allogenic HSCT patients were included in the study. Mean age was 52.4 years. 57.2% of patients were female. The most common underlying diagnoses were acute myeloid leukemia (38%), myelodysplastic syndrome (17%) and acute lymphoblastic leukemia (14%). 11.1% of the index admissions were complicated by CDI. Rates of aGVHD during the index admission or 100 days post-engraftment were similar between CDI and non-CDI groups: 13.8% vs. 12.1%, p=0.19 during index admission and 29.2% vs. 26.1%, p=0.09 during 100 days post-engraftment. Nonetheless, patients with CDI had longer length of hospital stay (34.6 vs 29.8 days, p<0.0001), higher hospitalization costs ($608K vs $506K USD) and greater rate of inpatient mortality (7.3% vs 4.6%, p<0.001). In the multivariate regression analysis, CDI during index admission was not associated with risk of development of aGVHD (Adjusted Odds Ratio 1.14, 95% Confidence Interval 0.87-1.48, p=0.34). Age and unrelated donor HSCT were predictive of risk of aGVHD. Conclusions: CDI during index admission was not predictive of aGVHD during the first 100 days post-allogenic HSCT. HSCT patients are frequency colonized with C.difficile. Diarrhea secondary to CDI may resemble gastrointestinal aGVHD. Therefore, overdiagnosis of CDI in this population is a concern. Antimicrobial stewardship and use of clinical decision support tools have been advocated recently to decrease testing of HSCT patients with C.difficile colonization.

Abstract Background: Achievement of target blood concentrations of cyclosporine (CsA) early after transplantation is known to be highly effective for reducing the incidence of acute graft versus host disease (aGVHD). However, no research has been conducted for predicting aGVHD occurrence with low CsA concentrations at different time periods. The objective of this study was to investigate the risk of aGVHD according to low CsA concentrations at lag days in children with allogenic hematopoietic stem cell transplantation (HSCT). Methods: The records of 61 consecutive children who underwent allogeneic HSCT and received CsA as prophylaxis against aGVHD between May 2012 and March 2015 were retrospectively evaluated. The main outcome was any association between low CsA concentrations at lag days and aGVHD occurrence, which was examined for the first month after transplantation. Mean CsA concentrations at three lag periods were calculated: lag days 0-6, 7-13, and 14-20 before aGVHD occurrence.Results: Patients whose mean CsA concentrations at lag days 0-6 did not reach the initial target concentration had 11.0-fold (95% confidence interval [CI]: 2.3-51.9) greater incidence of aGVHD. In addition, the AORs of low CsA concentrations at lag days 7-13 and 14-20 for developing aGVHD were 108.2 (95% CI: 7.7-1515.5) and 12.1 (95% CI: 1.1-138.1), respectively. Conclusions: After low CsA concentrations are detected, careful attention needs to be paid to prevent aGVHD.

Abstract Denileukin diftitox (Ontak), a recombinant protein composed of human interleukin 2 (IL-2) fused to diphtheria toxin, has selective cytotoxicity against activated lymphocytes expressing the high-affinity IL-2 receptor. We conducted a phase 1 study of denileukin diftitox in 30 patients with steroid refractory acute graft-versus-host disease (GVHD). Seven patients received 9 μg/kg intravenously on days 1 and 15; 18 received 9 μg/kg intravenously on days 1, 3, 5, 15, 17, and 19; and 5 received 9 μg/kg intravenously on days 1 to 5 and 15 to 19. Hepatic transaminase elevation was the dose-limiting toxicity (DLT), and dose level 2 was the maximum tolerated dose (MTD). Overall, 71% of patients responded with complete resolution (12 of 24; 50%) or partial resolution (5 of 24; 21%) of GVHD. Eight of 24 patients (33%) are alive at 6.3 to 24.6 months (median, 7.2 months). Denileukin diftitox is tolerable and has promising activity in steroid-refractory acute GVHD.

The mammalian intestinal microbiota is a complex ecosystem that plays an important role in host immune responses. Recent studies have demonstrated that alterations in intestinal microbiota composition are linked to multiple inflammatory diseases in humans, including acute graft-versus-host disease (aGVHD). aGVHD is one of the major obstacles in allogeneic hematopoietic stem cell transplantation (allo-HSCT), characterized by tissue damage in the gastrointestinal (GI) tract, liver, lung, and skin. Here, we review the current understanding of the role of intestinal microbiota in the control of immune responses during aGVHD. Additionally, the possibility of using probiotic strains for potential treatment or prevention of aGVHD will be discussed.
