Abstract
Graft-versus-host disease (GVHD) is a major complication of hematopoietic stem cell transplantation (SCT), leading to a significant morbidity and mortality. Histologically, gastrointestinal GVHD is characterized by crypt apoptosis and dropout. However, similar histologic features can also be seen in drug-induced injury and opportunistic infection. Knowledge of the timing of biopsy, patient medications, evidence of infection, and presence of GVHD at other organ sites can aid in the correct diagnosis and subsequent management of these patients. This review focuses on the pathologic differential diagnosis of apoptosis in gastrointestinal biopsies obtained from SCT patients.

Abstract
Graft-versus-host disease (GVHD) is a common and important complication of allogenic hematopoietic cell transplantation. The cardinal histologic feature of GVHD in the gastrointestinal tract is the presence of apoptotic bodies. To date, no study has evaluated the pathologic characteristics of gallbladder GVHD (GB-GVHD). In this study, we sought to describe their clinicopathologic features in a cohort of pediatric patients and compared them to a control group composed of 10 and 15 recent cases of acute and chronic cholecystitis, respectively. A total of 6 GB-GVHD cases were included, 5 cholecystectomies and 1 autopsy case(s), presenting in 2 boys and 4 girls, with a mean age of 6.7 years (1.5-18.6). The median days post-transplant to presentation was 261 (40-699), and all cases had GVHD involving other organs. GB-GVHD compared to the control groups was significantly associated with a younger age (P = .019), presence of apoptotic bodies and higher number of apoptotic bodies in 10 continuous mucosal folds and in 100 and 500 epithelial cells (all P < .001), and increased number of intraepithelial lymphocytes per 100 epithelial cells (P < .001). All patients were treated for GVHD with half of them achieving treatment response. Besides the autopsy case, all patients are alive with a median follow-up time of 45 months (4-212). The cause of death for the autopsy case was sepsis due to Pseudomonas aeruginosa. In our experience, the presence of both increased apoptotic bodies and intraepithelial lymphocytes in the gallbladder of hematopoietic cell transplantation patients should raise concern for GB-GVHD.

Abstract
Histomorpholgy is one of the mainstays of acute Graft-versus-host disease (GvHD) diagnosis. However, concerns about reproducibility and the most appropriate grading system question its usefulness. Our aim was to assess histomorphological parameters and previously reported grading systems for GvHD regarding reproducibility and validity. Moreover, we propose that sum scores, derived by combining separately scored morphological parameters into a total score, might provide a simplified but equally effective means to grade GvHD. A total of 123 colon biopsies were assessed across four pathologists for intestinal GvHD using a Round-Robin test and results were correlated with clinical findings. Interobserver reproducibility was high for histological parameters that were evaluated as indicators of acute GvHD. Published grading systems were moderately reproducible (ICC 0.679-0.769) while simplified sum scores, in comparison, showed better interrater reliability (ICC 0.818-0.896). All grading systems and sum scores were associated with clinical signs of GvHD and in part with therapy response and survival. However, they were not able to stratify patients according to the clinical severity of GvHD. In a hot-spot analysis 1 crypt apoptotic body (CAB) in 10 crypts was a reasonable cut-off value for minimal diagnostic criteria of GvHD. In conclusion, histology can contribute to the diagnosis of GvHD and is reproducible. Published grading systems are able to reflect clinical findings as are simplified sum scores, which showed improved reproducibility and might be easier to handle as they are based on adding up histological parameters rather than transferring histological findings into a separate grading system. Sum scores will have to be further tested in a prospective setting.

Abstract
Graft-versus-host disease (GVHD) remains a major complication for patients who have undergone hematopoietic stem cell transplantation. The Lerner system is the most widely used histologic grading score for gastrointestinal GVHD but its clinic utility is debated. The aim of our study was to develop a novel histologic grading system for gastrointestinal GVHD that incorporates independent evaluation of both apoptotic counts and crypt destruction. Colonic biopsies taken to assess for GVHD were retrospectively assessed for: Crypt damage (No crypt dropout or ulceration-0; crypt dropout without ulceration-1; ulceration-2) and crypt apoptotic counts (No apoptosis-0; 1-6 apoptotic bodies per 10 contiguous crypts-1; >6apoptotic bodies per 10 contiguous crypts-2). The two scores were added together to get an overall grade (0-4). Alternative apoptotic cutoff points were examined. An apoptotic cutoff of >9 apoptotic bodies per 10 contiguous crypts marginally improved the area under the curve (AUC), but the AUCs from the resulting novel grade calculations were not significantly different (p = 0.10). Lerner grading was also applied. The study group consisted of an initial analysis cohort (n = 191) and a second validation cohort from a separate institution (n = 97). In the initial analysis cohort, our histologic grading system provided prognostic stratification for GVHD-related death within 6 months (p = 0.0004, AUC = 0.705). The Lerner system performed similarly in terms of providing prognostic stratification for GVHD-related death (p = 0.0001, AUC = 0.707). In the external validation cohort, our histologic grading system was not associated with GVHD-related death (p = 0.14, AUC = 0.621), but the Lerner system was associated with GVHD-related death (p = 0.048, AUC = 0.663). While our grading system may have some advantages compared to the Lerner system, due to lack of reproducibility we do not currently recommend widespread adoption of this system. Nonetheless, we present a standardized tool for assessing both apoptosis and crypt damage. Future studies assessing alternative histologic grading systems with external validation and further examination the lower apoptotic threshold for GVHD diagnosis are warranted.

Abstract
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.

Terminal ileum is the most sensitive site for the histologic diagnosis of grade 4 graft-versus-host disease (GvHD) in the lower GI tract and is a harbinger of poor outcome. Virchows Arch 2021; 479:919-925.

Abstract
The site of the gastrointestinal (GI) tract where biopsies are most likely to be diagnostic of graft-versus-host disease (GvHD) remains controversial. Recent reports have indicated that biopsies from the rectosigmoid have sufficient sensitivity and specificity for diagnosing GI GvHD and can be obtained via a less invasive flexible sigmoidoscopy procedure. While GvHD histologic grades 1-3 have little correlation with patients' symptoms and overall clinical grade, histologic grade 4 GvHD does correlate with severe clinical presentation and a poor prognosis. We examined cases of lower GI biopsies obtained via a complete colonoscopy with ileal intubation for the evaluation of GvHD within a 2-year period from patients who underwent stem cell transplantation. In our study cohort, grade 4 GvHD was significantly more likely to be identified in a terminal ileum biopsy than in a biopsy from another site in the lower GI tract. Significantly, 5 of 6 patients with histologic grade 4 GvHD diagnosed on ileal biopsies died from complication of severe GI GvHD. Given the poor prognosis of histologic grade 4 GvHD in the terminal ileum, the detection of this finding may serve to inform clinicians that escalation or modification of treatment may need to be considered. Furthermore, our findings suggest that terminal ileal biopsies may help to increase sensitivity for identifying patients at high risk for poor outcome of GvHD.

Abstract
BACKGROUND No previous paediatric study has evaluated the frequency of diagnostic disagreement between clinical standard histopathological assessment (CSHA) and retrospective, independent, histopathological assessment (RIHA) of gastrointestinal Graft-Versus-Host Disease (GI-GVHD) METHODS: In a retrospective cohort study, based on gastrointestinal biopsies collected from allogeneic HSCT-treated children (<18 years) with symptom-based GI-GVHD, we evaluated; disagreement of histopathology-based GI-GVHD diagnosis in CSHA vs RIHA, and potential clinical consequences of differences between the assessments. The CSHA-based diagnoses were retrieved from histopathology reports. The RIHA was performed by one pathologist, blinded to the CSHA outcomes and based on the minimal criteria for histopathology-based GI-GVHD diagnosis by the NIH 2014. RESULTS Seventy children with 92 endoscopic occasions (including 22 re-endoscopies) were enrolled. GI-GVHD was observed in 73% (67/92) of the endoscopies in the RIHA and in 54% (50/92) in the CSHA (P = .014). The RIHA confirmed 94% (47/50) with GI-GVHD and 52% (22/42) with non-GI-GVHD diagnoses, established in the CSHA. Disagreement, that is endoscopic occasions with GI-GVHD solely detected in RIHA or detection of GI-GVHD in CSHA but not in RIHA, was observed in 20/42 (48%) and 3/50 (6%), respectively (McNemar's test, P = .0008). The risk of a subsequent re-endoscopy was higher in endoscopic occasions with GI-GVHD detected in RIHA but not in CSHA vs if non-GI-GVHD were detected in both readings (P = .005). CONCLUSION Our results suggest that in children with symptom-based GI-GVHD without histopathological confirmation in CSHA, a second, NIH 2014 based histopathological assessment should be considered before performing a re-endoscopy.

Abstract
Data regarding the lower diagnostic threshold for gastric graft-versus-host disease is lacking. The aim of this study was to review a cohort of gastric biopsies taken to evaluate for graft-versus-host disease, and to correlate histologic findings with clinical and endoscopic evidence of graft-versus-host disease as well as biopsy findings from other locations to define a lower diagnostic threshold for gastric graft-versus-host disease. Gastric biopsies were evaluated for the maximum number of apoptotic bodies per 10 contiguous gastric pits, presence of ≥1 apoptotic body per biopsy (NIH criteria), and presence of gastric pit dropout and/or ulceration. To evaluate histologic specificity, sixty gastric biopsies from non-stem cell transplant patients were selected as a control group. Clinical information was collected from chart review. The study group consisted of 65 gastric biopsies from 52 stem cell transplant patients. The mean apoptotic count per 10 contiguous gastric pits for stem cell transplant biopsies was 1.8 (range 0-8) and for control cases 1.0 (range 0-5). Nineteen stem cell transplant biopsies (29%) had ≥1 apoptotic body per biopsy and only a single case had >6 apoptotic bodies per 10 contiguous gastric pits. When the NIH guidelines were combined with presence of at least two apoptotic bodies per 10 contiguous gastric pits, this cutoff point was significantly associated with treatment for graft-versus-host disease (OR = 9.4, 95% CI = 1.7-176.7, p = 0.04) and evidence of extraintestinal graft-versus-host disease (OR = 3.2, 95% CI = 1.1-10.7, p = 0.04). The diagnostic specificity for our proposed cutoff value is 94%. We present criteria for the lower diagnostic threshold of gastric graft-versus-host disease, which uses a lower apoptotic cutoff value than has been utilized in colonic biopsies. Although sensitivity remains a challenge for gastric graft-versus-host disease biopsies, this newly proposed cutoff provides higher specificity than NIH guidelines alone and better correlates with clinical evidence of graft-versus-host disease.

Abstract
AimsThe hallmark histological feature of acute gastrointestinal graft versus host disease (GI GVHD) is epithelial apoptosis. This is the first formal evaluation of how many serial sections are required to consistently detect apoptotic bodies in endoscopic biopsies from various GI locations in patients with clinically validated GI GVHD.Methods, results and conclusionsAssessment of 1008 serial sections showed that apoptotic bodies are uniformly distributed among such sections of gastric, duodenal and colorectal biopsies from these patients. Assessment of 59 further biopsies showed that assessing 12 serial sections should suffice to detect GVHD in gastric, duodenal and colorectal biopsies using thresholds of one apoptotic body per biopsy fragment or one apoptotic body per 4 mm2. Assessing 12 serial sections should also suffice to detect GVHD in duodenal and colorectal biopsies using the threshold of 6 apoptotic bodies per 10 contiguous crypts, but it remains uncertain whether this assessment and threshold can be applied to gastric biopsies.

Abstract
BACKGROUND AND AIMS Children with very early onset inflammatory bowel disease [VEO-IBD] represent a unique cohort, often with a severe phenotype that is refractory to conventional medications, and some cases have underlying primary immunodeficiencies. Previous work has identified distinct histopathological patterns in the gastrointestinal tract in patients with primary immunodeficiencies. The aim of this study is to characterise the diagnostic histological findings in patients with VEO-IBD as compared with older onset paediatric IBD, and determine if there are unique pathological changes that can shed light on the driving forces of the disease, particularly immunodeficiencies. METHODS Clinical retrospective chart review, including disease characteristics and endoscopic findings, was performed on all included subjects. Two paediatric pathologists reviewed biopsies from diagnostic upper endoscopies and colonoscopies of subjects with very early onset inflammatory bowel disease and older onset inflammatory bowel disease, to evaluate for the presence of 11 histological features previously associated with inflammatory bowel disease and primary immunodeficiencies. RESULTS The diagnostic gastrointestinal biopsies of subjects with very early onset inflammatory bowel disease differed from those in older onset paediatric IBD, demonstrated by increased frequency of apoptosis, severe chronic architectural changes, small intestine villous blunting, and eosinophils in the crypts, lamina propria, and surface epithelium. CONCLUSIONS The diagnostic biopsies of children with very early onset inflammatory bowel disease can identify characteristic features that may be important in guiding the diagnostic work-up in this population.

Abstract
The pathologic interpretation of gut biopsies in hematopoietic cell transplant recipients to assess graft-versus-host disease (GVHD) is well accepted and supplements clinical and endoscopic findings. However, the histologic activity grading of GVHD is controversial, with attempts to predict prognosis or response to treatment largely unsuccessful. GVHD is being diagnosed earlier in its course, raising the possibility that the pathologic grading system can be profitably modified. We developed a histologic activity grading system designed to replace the commonly used modified Lerner grading systems. Our system stratifies the low-level Lerner grade I category into 4 activity grade categories, based on the average frequency of apoptotic cells. The results are expressed as ordinal categories: GVHD of minimal, mild, moderate, severe histologic activity, or severe histologic activity with destruction (activity grades 1 to 5). In a retrospective study, we studied 87 consecutive cases with 201 post-transplantation specimens (median, 48 days; range, 18 to 1479 days) of stomach, duodenum, and colorectum, which had been activity graded at the time of the original diagnosis. Most of the biopsies diagnosed as GVHD were low grade-minimal (11%) or mild (71%) histologic activity. We hypothesized that the higher activity grades would be associated with more therapeutic intervention. The odds of increased therapy in the combined all-site specimens were increased as activity grade increased (odds ratio, 2.9 [95% confidence interval {CI}, 1.9 to 4.5]; P = < .0001). Thus, our grading system was validated. To investigate whether the activity grade was associated with therapy within the formerly undivided Lerner grade I category, the analysis was restricted to these 174 all-site specimens. The validation result was similar (odds ratio, 3.1 [95% CI, 1.3 to 7.2]; P = .009). This result interestingly suggests that there is useful information hidden in the Lerner grade I category, which could potentially guide immediately actionable treatment decisions. This histologic activity grade system has been in use at our institution for over 2 years with good acceptance.
