Chronic graft versus host disease (cGvHD) is the most common cause for non-relapse mortality post allogenic hematopoietic stem cell transplant (HSCT). However, there are no well-defined biomarkers for cGvHD or late acute GvHD (aGvHD). This study is a longitudinal evaluation of metabolomic patterns of cGvHD and late aGvHD in pediatric HSCT recipients. A quantitative analysis of plasma metabolites was performed on 222 evaluable pediatric subjects from the ABLE/PBMTC1202 study. We performed a risk-assignment analysis at day+100 on subjects who later developed either cGvHD or late aGvHD after day 114 to non-cGvHD controls. A second analysis at diagnosis used fixed and mixed multiple regression to compare cGvHD at onset to time matched non-cGvHD controls. A metabolomic biomarker was considered biologically relevant only if it met all three selection criteria: a) p value ≤0.05, b) effect ratio of ≥1.3 or ≤0.75, and c) receiver operator characteristic AUC ≥0.60. We found a consistent elevation in plasma alpha-ketoglutaric acid before (Day + 100) and at the onset of cGvHD, not impacted by cGvHD severity, pubertal status, or previous aGvHD. In addition, late aGvHD had a unique metabolomic pattern at day+100 compared to cGvHD. Additional metabolomic correlation patterns were seen with the clinical presentation of pulmonary, de novo, and progressive cGvHD. Alpha-ketoglutaric acid emerged as the single most significant metabolite associated with cGvHD, both in the day +100 risk-assignment and later diagnostic onset analysis. These distinctive metabolic patterns may lead to improved subclassification of cGvHD. Future validation of these exploratory results are needed.

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.

Post Transplant

Post-hematopoietic stem cell transplant secondary solid neoplasms are uncommon and usually host-derived. We describe a 6-year-old female who developed a mixed donor-recipient origin mesenchymal stromal tumor-like lesion in the liver following an unrelated hematopoietic stem cell transplant complicated by severe graft-versus-host disease. This lesion arose early post-transplant in association with hepatic graft-versus-host disease. At 12 years post-transplant, the neoplasm has progressively shrunken in size and the patient remains well with no neoplasm-associated sequelae. This report characterizes a novel lesion of mixed origin post-transplant and offers unique insights into the contribution of bone marrow-derived cells to extra-medullary tissues.

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.

Graft Versus Host

Graft-versus-host disease has been reported to occur rarely in syngeneic hematopoietic stem cell transplant recipients. Clinical and histological changes consistent with graft-versus-host disease have been reported to occur in this patient population. We report a case of a 46-year-old Caucasian male with diffuse large B-cell lymphoma in complete remission who underwent a syngeneic hematopoietic stem cell transplant. He was diagnosed with grade III acute skin and gastrointestinal graft-versus-host disease requiring high-dose corticosteroids and immunosuppressive therapy and resulting in a complete response. Syngeneic graft-versus-host disease is an anomaly that needs to be considered as a differential diagnosis of patients experiencing dermatitis, gastroenteritis, or hepatitis after an identical twin hematopoietic stem cell transplant.

Graft versus Host Disease (GVHD) can present with mucocutaneous, gastrointestinal and hepatic manifestations, specifically a cholestatic transaminitis. Rarely, some cases can present with only a hepatocellular transaminitis. Our patient presented with an acute hepatitis on day +90 post-hematopoietic stem cell transplant, without other overt manifestations of GVHD. The initial work up was negative for a viral etiology or causative drug, and the patient’s transaminases continued to rise. On day +96, an erythematous rash appeared with biopsy indicating lymphocytic and eosinophilic infiltrates concerning for cutaneous GVHD. Subsequently, a liver biopsy was obtained, and showed marked ductopenia with cholestasis, consistent with hepatic GVHD.

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.

Context.— Despite advances in therapeutic and preventive measures, hematopoietic stem cell transplant recipients remain at risk for a variety of gastrointestinal and liver complications. Objective.— To detail the pathologic features of the various gastrointestinal and liver complications occurring after hematopoietic stem cell transplantation in relation to their clinical context. The specific complications covered include graft-versus-host disease, mycophenolate mofetil–induced injury, timeline of infections, neutropenic enterocolitis, gastrointestinal thrombotic microangiopathy, sinusoidal obstruction syndrome, hepatic iron overload, and the controversy around cord colitis syndrome. Data Sources.— The content of this article is based on pertinent peer-reviewed articles in PubMed, relevant textbooks, and on the authors' personal experiences. Conclusions.— The final histopathologic diagnosis requires the integration of clinical and histologic findings and the exclusion of other competing causes of injury. Review of the clinical data, including the original disease pretransplant, the type of transplant, the timing of the gastrointestinal and/or liver manifestations, the timing of the biopsy after transplant, the presence of graft-versus-host disease in other organs and sites, the list of drug regimens, and the clinical and laboratory evidence of infection, is the key to reaching the proper histologic diagnosis.
