We report three autopsy cases of congenital cytomegalovirus (CMV) infection in fetuses with a review of literature. The clinical manifestations in these cases of congenital CMV infection include intrauterine fetal death, hydrops fetalis, and CMV pneumonia associated with cardiovascular defect. The pathological characteristics were as follows: 1) the kidney was the most frequently involved organ, followed by lung and liver, 2) CMV inclusions were found predominantly in epithelial cells and to a lesser degree in endothelial cells, 3) intrahepatic bile duct epithelial cells were frequently involved, and 4) inflammatory reaction around CMV inclusions was not prominent in the early stage of pregnancy. Diagnostic confirmation was obtained by in situ hybridization (ISH) using a biotinylated CMV-DNA probe, which demonstrated intranuclear inclusions and sometimes recognized cells that did not show intranuclear inclusion.

OBJECTIVE: To explore the risk factors of cytomegalovirus (CMV) and refractory CMV infection (RCI) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and their influences on survival. METHODS: A total of 246 patients who received allo-HSCT from 2015 to 2020 were divided into CMV group (n=67) and non-CMV group (n=179) according to whether they had CMV infection. Patients with CMV infection were further divided into RCI group (n=18) and non-RCI group (n=49) according to whether they had RCI. The risk factors of CMV infection and RCI were analyzed, and the diagnostic significance of Logistics regression model was verified by ROC curve. The differences of overall survival (OS) and progression-free survival (PFS) between groups and the risk factors affecting OS were analyzed. RESULTS: For patients with CMV infection, the median time of the first CMV infection was 48(7-183) days after allo-HSCT, and the median duration was 21 (7-158) days. Older age, EB viremia and gradeⅡ-Ⅳacute graft-versus-host disease (aGVHD) significantly increased the risk of CMV infection (P=0.032, <0.001 and 0.037, respectively). Risk factors for RCI were EB viremia and the peak value of CMV-DNA at diagnosis≥1×10⁴ copies/ml (P=0.039 and 0.006, respectively). White blood cell (WBC)≥4×10⁹/L at 14 days after transplantation was a protective factor for CMV infection and RCI (P=0.013 and 0.014, respectively). The OS rate in CMV group was significantly lower than that in non-CMV group (P=0.033), and also significantly lower in RCI group than that in non-RCI group (P=0.043). Hematopoietic reconstruction was a favorable factor for OS (P<0.001), whereas CMV-DNA≥1.0×10⁴ copies/ml within 60 days after transplantation was a risk factor for OS (P=0.005). CONCLUSION The late recovery of WBC and the combination of EB viremia after transplantation are common risk factors for CMV infection and RCI. CMV-DNA load of 1×10⁴ copies/ml is an important threshold, higher than which is associated with higher RCI and lower OS risk.

Cytomegalovirus (CMV) infections are commonly reported in severely immunocompromised hosts and ulcers of the alimentary tract are frequently observed in systemic CMV infections. However, invasive and ulcerative disease of the gastrointestinal (GI) tract caused by CMV has also been reported in healthy adults. Many reports show that a CMV infection can produce localized ulcerations in the esophagus, stomach, small intestine, and colon in nonimmunocompromised individuals. The most common site of involvement by CMV infection in the GI tract is the colon followed by the upper GI tract and the least common site is the small intestine. Although GI bleeding is one of the major presenting symptoms of patients with CMV infections of the GI tract, lower GI bleeding due to CMV ileal ulcers in immunocompetent patients, to our knowledge, has not been reported in the English literature. Recently, we experienced a case of lower GI bleeding due to CMV ileal ulcers in a 57-year-old man who had no evidence of immunocompromise. This case suggests that small intestinal ulcers due to CMV infection should be included in the differential diagnosis of lower GI bleeding even in immunocompetent hosts.
