Journal of Experimental Hematology 2003;11(2):213-216
Chronic graft-versus-host disease (cGVHD) continues to be a major complication in long-term survivors after allogeneic hematopoietic stem cell transplantation and is the principal cause of morbidity and non-relapse mortality. With the new approaches in the immune mechanisms of cGVHD, the diagnosis, prophylaxis and treatment of cGVHD are involved. This review summarises the current progress of research on cGVHD.

Thrombotic microangiopathy (TMA) is a lethal transplantation-associated complication which exactly likes acute intestinal graft-versus-host disease (GVHD) in the clinical manifestation. 373 consecutive patients with hematological diseases received family HLA matched or mismatched HCT from May, 2002 to July, 2004. To analyse the clinical and pathological characteristics of TMA, 30 patients who suffered from severe diarrhea and received colonoscopic examination and gut biopsy were retrospectively analyzed. The results indicated that 7 patients originally diagnosed as gut GVHD showed the pathological evidence of enteric TMA. The incidence of TMA was 7 out of 30 specimen (23.3%). Pathological evidence of enteric TMA shown microvascular disorder characterized by thrombus in the capillary without infiltration of lymphocytes and perivascular hemorrhages in the mucosa, swelling and focal denudation of epithelial cells. All patients with TMA were associated with cytomegalovirus (CMV) antigenemia/disease. Among these patients, 4 cases, who only showed TMA without the evidence of gut GVHD pathologically, displayed treatment-resistant bloody diarrhea, renal failure, veno-occlusive disease, hemorrhagic cystitis, hemolytic anemia as well as thrombocytopenia. But the other 3 cases, with co-existence of both TMA and GVHD pathological characteristics had better treatment response. Survival analysis indicated that 3 patients with TMA-GVHD survived for 461 to 536 days but three out of four TMA patients died from VOD with liver failure as well as multiple organ failure during 101 to 254 days after HCT. In conclusion, to better diagnose those patients with severe and refractory diarrhea following HCT, pathological examination may indicate crux evidence to identify intestinal TMA from gut GVHD. Furthermore, this primary report has first evidenced that TMA and TMA-GVHD are two pathologically well-recognized subtypes with the difference between the pathological characteristics, treatment response and clinical outcomes.

OBJECTIVETo analyze the kinetics of hematopoietic cell chimerism in the early period after non-myeloablative stem cell transplantation (NAST) and to investigate the correlation between molecular and hematologic assessment of engraftment or rejection.
METHODShort tandem repeat-polymerase chain reaction (STR-PCR) analysis of chimerism status was carried out in 6 patients who received NAST from HLA-matched sibling donors.
RESULTSIn 5/6 patients, the peripheral blood samples collected on the first day after allograft infusion displayed the presence of mixed chimerism. STR-PCR analysis revealed a gradual increase of the donor-specific allelic signal which became dominant over the recipient-specific allele by day +7. On day +14, hematologic chimerisms were completely donor origin. Their molecular engraftments (ME) were detected at a median time of 6 days, preceding hematologic engraftment by a median of 5 days (P > 0.05). But the sixth patient showed more than 50% host residual cells on day +7 and had no signs of ME on day +14.
CONCLUSIONIt suggested that molecular monitoring of the early dynamics of chimerism after NAST could be useful in predicting engraftment, or rejection. If the engraftment was less than 50% on day +7 and failed to get ME on day +14, the graft rejection would occur.

OBJECTIVETo analyze the specificity, sensitivity and receiver operating characteristic (ROC) curve of plasma elafin for diagnosis of skin acute graft-versus-host disease (aGVHD), and to explore its clinical diagnostic value.
METHODSIncidence of skin aGVHD from fifty-three patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) were observed prospectively in Guangdong General Hospital from Apr 2010 to Aug 2011. The plasma concentrations of elafin were detected by enzyme-linked immunosorbent assay (ELISA). Skin biopsies were taken from 28 patients with skin rash, and elafin expression in the skin was detected by immunohistochemistry. Positive expression was defined as significant staining of at 50% of the depth of the epidermis, excluding the granular cell layer and the acrosyringium.
RESULTSAmong 28 patients with skin rash, twenty-five were considered as skin aGVHD by clinical diagnosis, seventeen were confirmed as skin aGVHD by pathological biopsy. 11 cases were elafin positive by immunohistochemical staining. Elafin protein was overexpressed in aGVHD skin tissue (P = 0.001). Plasma concentrations of elafin were significantly higher in patients with skin aGVHD (positive) group than in those without skin aGVHD (negative) group (P = 0.005), among which there being no statistically significant difference in plasma elafin level between patients with grade I skin aGVHD group and negative group(P = 0.971), but being statistically significant difference compared patients with grade II-IV skin aGVHD group with those with grade I skin aGVHD group (P = 0.02) and with negative group (P = 0.008). Using the pathological diagnosis as the gold standard, the estimated specificity and the sensitivity of clinical diagnosis criteria were 27.3% and 100%, respectively, and those of tissue elafin protein level were 100% and 64.7%, respectively. The area under the ROC curve was 0.909 (0.797 - 1.021) when plasma concentrations of elafin was used in diagnosis of skin aGVHD. The sensitivity was 82.4% and the specificity was 81.8 % when the critical value was set at 1456.043 µg/L.
CONCLUSIONPlasma concentration of elafin is significantly higher at the onset of skin aGVHD. It can be used as biochemical marker of skin aGVHD and has higher value in diagnosis of skin aGVHD.

BACKGROUNDGastrointestinal graft versus host disease (GI-GVHD) and cytomegalovirus (CMV) enteritis are important complications following allogeneic haematopoietic stem cell transplantation (allo-HSCT). We explored the role of colonoscopy in the diagnosis of GI-GVHD and CMV enteritis following allo-HSCT to identify the endoscopic manifestations of GI-GVHD and CMV enteritis was made.
METHODSA retrospective analysis of the colonoscopic manifestations of GI-GVHD, CMV enteritis and GI-GVHD with concurrent CMV enteritis (GconC) and their related clinical issues.
RESULTSForty-seven patients underwent 50 colonoscopies with diagnoses of 32 GI-GVHD, 7 CMV enteritis and 11 GconC. Both GI-GVHD and CMV enteritis had colonic mucosal lesions with various manifestations under colonoscopy. Tortoise shell like changes of the mucosa (12 of 32) and deep ulcers (2 of 7) were specific endoscopic manifestations for GI-GVHD and CMV enteritis, respectively, while mucosal oedema, erythema, congestion, erosion and shallow ulcers could not be used to differentiate GI-GVHD from CMV enteritis. GconC patients were prone to have oozing bleeding of the end ileal mucosa and typhlodicliditis. Of the biopsed specimens for GI-GVHD, CMV enteritis and GconC, 64%, 70% and 44% were taken from the rectum and sigmoid colon respectively.
CONCLUSIONSFollowing allo-HSCT, tortoise shell like changes and deep ulcers of the colonic mucosa are characteristic changes for GI-GVHD and CMV enteritis, respectively, while the other lesions are not. Most of the GI-GVHDs and CMV enteritis cases can be diagnosed by left colon examination and tissue biopsy, but total colon examination to the terminal ileum is preferred.

Allogeneic stem cell transplantation (allo-SCT) using related or unrelated donor could eradicate paroxysmal nocturnal hemoglobinuria (PNH) clones and may cure the disease. Chronic graft-versus host disease (GVHD) is a major complication of patients who have undergone allo-SCT. Nephrotic syndrome has been described as one of the rare manifestations of chronic GVHD following the usual myeloablative allo-SCT. We report a case of nephrotic syndrome that developed 25 months after non-myeloablative allo-SCT for PNH. The patient had grade II acute GVHD and extensive chronic GVHD after non-myeloablative allo-SCT. Typically the patient presented with preserved renal function and full nephrotic syndrome including generalized edema, proteinuria, hypoalbuminemia, and hypercholesterolemia. Renal biopsy revealed findings of membranous glomerulopathy (MG). The patient is alive with a stable engraftment and full donor chimerism under the administration of tacrolimus for control of chronic GVHD and MG without refractory hemolysis and cytopenia.

Chimerism testing permits early prediction and documentation of successful engraftment, and also facilitates detection of impending graft rejection. In this study, we serially monitored chimerism status by short tandem repeat-based PCR in nucleated cells (NC), T cells and natural killer (NK) cells after myeloablative allogeneic stem cell transplantation (SCT). Four patients with myeloid malignancies showed discrepant chimerism results among those three fractions. Three patients had mixed chimerism (MC) of donor/host T cells at a time point around the onset of chronic graft-versus-host disease (GVHD). In two patients with disease relapse, MC of NK cells preceded a morphological relapse or NK cells showed a higher percentage of patient cells compared to NC. Therefore, our study shows that chimerism analysis in lineage-specific cells might be useful in predicting clinical outcome after allogeneic SCT in certain patients.

This study was aimed to investigate the role of sequence similar matching (SSM) method in prediction of GVHD after HLA unmatched allogeneic hematopoietic stem cell transplantation (allo-HSCT). The data from 23 patients undergoing HLA unmatched allo-HSCT were analyzed and calculated by SSM method. The results showed that the incidence of acute and severe GVHD were significantly less in the allo-HSCT cases with total SSM value less than 55. In conclusion, the SSM method can be used to predict GVHD in the HLA-unmatched allogeneic hematopoietic stem cell transplantation.

This study was purposed to investigate the clinical features and related factors influencing prognosis of patients with severe intestinal graft-versus-host disease (siGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). 710 patients received allo-HSCT in Beijing Dao-Pei hospital from Jan 2007 to Jan 2011 were enrolled in this study. A total of 34 patients with siGVHD out of 710 patients were analyzed retrospectively, and the univariate analysis for related factors influencing prognosis were carried out by using SPSS 19.0 software. The results showed that the incidence of siGVHD was 4.79%, its medium occurrence time was 29 (18 - 210) days after allo-HSCT. 18 out of 34 patients with siGVHD received colonoscopy, among them 6 patients were complicated with viral enteritis. The deep ulcers could be found under colonoscope. Histopathologic examination revealed the viral inclusion bodies or positive viral antigen. Methylprednisolone (MP), cyclosporine A (CsA) or tacrolimus combined CD25 monoclonal antibody and oral budesonide were used for treatment of siGVHD. 29 out of 34 cases achieved complete response (CR) with CR rate of 85.29%, overall survival rate was 58.82% (20/34). 9 out of 29 cases achieving CR died of other complications. The univariate analysis of the related factor indicated the hyperacute GVHD is the adverse factor influencing overall survival of patients with siGVHD. It is concluded that early colonoscopy is an effective way for definitive diagnosis of siGVHD. The combined treatment including MP, CsA or tacrolimus, CD25 monoclonal antibody and oral budesonide shows a significant curative effects. Intensive treatment of complications in late period of GVHD can enhance the overall survival rate.
