Viruses 2024; 16:346. [PMID: 38543712 PMCID: PMC10975113 DOI: 10.3390/v16030346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 02/17/2024] [Accepted: 02/22/2024] [Indexed: 05/23/2024] Open
Abstract
Cytomegalovirus (CMV) is a potential pathogen that causes gastrointestinal (GI) tract diseases regardless of host immunity. In contrast to immunocompromised individuals, immunocompetent patients lack a comprehensive overview of the gastrointestinal manifestations. This study aims to provide a comprehensive summary of the current evidence regarding presentations, diagnostics, management, risk assessment, and outcomes in immunocompetent patients with CMV GI disease. A thorough literature search of English publications up to April 2022 was conducted across electronic databases to identify relevant articles, with eligible case series selected for detailed analysis. The majority of immunocompetent patients affected by CMV GI disease are typically elderly, critically ill, or burdened with comorbidities that compromise immunity. Clinical presentations range from subtle symptoms to severe surgical conditions, including instances of mortality. Specific clinical presentations, blood test results, or endoscopic features are lacking, necessitating reliance on histopathological tests such as immunohistochemistry staining for diagnosis. While antiviral therapy may offer benefits in improving outcomes, careful individual assessment is warranted due to diverse comorbidities and potential side effects. Mortality rates vary considerably based on underlying medical conditions and therapeutic approaches. It is imperative for clinicians to maintain vigilance for CMV GI disease among high-risk groups, despite their baseline immunocompetence, in order to enhance clinical outcomes.

Abstract
Background Cytomegalovirus (CMV) reactivation may occur as the shedding of the virus from various body sites or could represent an active disease that might be fatal if untreated. Distinguishing between the two states may prove very difficult. The role of the CMV disease in patients with hematological malignancies or transplant patients is more defined than that in other immunocompromised patients where neither anti-CMV prophylaxis is used nor plasma CMV levels are monitored. Here, we try to examine cases with CMV viremia in the latter group of patients in an attempt to make a distinction between CMV infection and disease to determine which patients would benefit from treatment. Methods Elderly patients, patients with rheumatological disorders, and patients with inflammatory bowel disease (IBD) and with clinical suspicion of CMV disease who were referred to the infectious diseases service at Sultan Qaboos University Hospital were examined from 1 January 2018 to 31 January 2023. We added a patient we found in our referral log book from 2012. Clinical, epidemiological, and laboratory data were retrieved from the hospital information system. Plasma CMV levels and CMV body fluid levels including pulmonary samples obtained from bronchoalveolar lavage (BAL) in suspected cases of CMV pneumonitis and gastrointestinal (GI) CMV levels obtained from stool and gastrointestinal tissue biopsies in suspected cases of gastrointestinal CMV disease were collected. COBAS® AmpliPrep/COBAS® TaqMan®assay (Roche Molecular Systems, Inc., Branchburg, NJ) was used to measure CMV copies per milliliter. Results A total of 28 patients were considered to have CMV disease, 12 of whom were elderly (≥60 years) and the rest were young and middle aged (Y/M). The most common comorbidities of the elderly included chronic kidney disease (CKD), hypertension (HTN), and diabetes mellitus (DM). In the Y/M group, seven patients had systemic lupus erythematosus (SLE), one had antineutrophil cytoplasmic antibody (ANCA) associated vasculitis, four patients had IBD, two had IBD plus primary immunodeficiencies (one patient had agammaglobulinemia and one had combined deficiencies), and one patient had combined immunodeficiency. CKD was a common finding in the SLE patients. Diarrhea was the most common CMV presentation occurring in 19 patients (67.9%), being bloody in 10 patients. Four patients had pulmonary presentations, and four had hematological presentations in the form of anemia or pancytopenia. Nineteen patients were given CMV antiviral treatment, and one patient received it during the first episode but not in the second episode. Twenty-eight-day mortality in the treated group was 20% versus 55.5% in the untreated group. The majority of the deaths occurred in the SLE and elderly patients. Thrombocytopenia occurred in 60.7%, 70.6% of whom died signaling a potential predictive role for thrombocytopenia in early empirical CMV antiviral treatment and in prognosis. Conclusion The difficulty in distinguishing CMV infection from CMV disease remains a concern in the elderly and SLE patients. In our small study, there was a survival benefit in early screening for CMV and initiating preemptive CMV antiviral therapy in these two groups even before CMV disease is proven. This urgency was not observed for patients with IBD or primary immunodeficiencies. A major common factor for CMV disease was CKD, whereas thrombocytopenia was an indicator of disease and prognosis.

Cytomegalovirus cell tropism and clinicopathological characteristics in gastrointestinal tract of patients with HIV/AIDS. Diagn Pathol 2022; 17:9. [PMID: 35027044 PMCID: PMC8759214 DOI: 10.1186/s13000-022-01193-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 01/02/2022] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Cytomegalovirus (CMV) has been recognized as one of the frequently occurring opportunistic infections (OIs) reported in the patients having human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). In addition, it has been identified as the factor leading to gastrointestinal (GI) tract disorder among HIV/AIDS population. CMV exhibits broad cell tropism in different organs. This study evaluated the CMV cell tropism and clinicopathological characteristics of CMV infection in the different GI regions in HIV/AIDS cases. METHODS Using nucleic acid in situ hybridization (ISH), CMV was detected in the gastrointestinal mucosal biopsy samples. The paraffin-embedded samples were stained with hematoxylin and eosin (HE) and immunohistochemistry (IHC), respectively. RESULTS A total of 32 HIV/AIDS patients were enrolled in this study. Fourteen of these patients underwent gastroscopy, while the remaining eighteen received colonoscopy. CMV-infected cells were observed at 46 GI sites. Among them, the colon was the region with the highest susceptibility to GI CMV infection (n = 12, 26.1%). The CMV giant cell inclusion bodies were detected in epithelial cells and mesenchymal cells, including histiocytes, smooth muscle cells, fibroblasts, and endothelial cells. In the duodenum, there were markedly more positive epithelial cells than mesenchymal cells (p = 0.033). In contrast, in the esophagus (p = 0.030), cardia (p = 0.003), rectum (p = 0.019), colon (p < 0.001), and cecum (p < 0.001), there were notably less positive epithelial cells than mesenchymal cells. The expression levels of PDGFRα and Nrp2 in the mesenchymal cells were higher than the epithelial cells in cardia, cecum, colon, sigmoid, and rectum, especially in the areas with ulcers. However, Nrp2 in the epithelial cells was higher than that in the duodenum. Moreover, the positive CMV DNA in peripheral blood was related to the CMV-positive cell count, as well as the ulceration in GI tract (p = 0.035 and 0.036, respectively). CONCLUSIONS The colon has been identified as the GI site with the highest susceptibility to CMV infection. There are different CMV-infected cells in the different sites of the GI that relate to the expression level of PDGFRα and Nrp2. CMV DNA positive in the blood is related to the positive CMV cell count, as well as ulceration in the GI tract.

Abstract
OBJECTIVES Herpes simplex virus (HSV) and cytomegalovirus (CMV) immunohistochemical stains (IHC) are frequently applied on esophageal biopsies. Our aims were to identify IHC use patterns in viral esophagitis (VE), and clinicopathologic features of VE that could guide IHC use. METHODS We included 58 VE cases and 60 controls, defined as patients with negative HSV/CMV IHC between January 2006 and July 2017. Biopsies were reviewed and histologic features and clinical data recorded. RESULTS Thirteen cases required IHC for diagnosis. IHC was performed in 13 HSV and 5 CMV cases where diagnostic viral inclusions were present. VE patients were more likely to have endoscopic ulcer (P=0.002) and be immunocompromised (P<0.001). Pretest clinical concern for VE was common (P=0.006). Histologically, VE patients were more likely to have ulcer (P=0.004), ulcer exudate rich in neutrophils and histiocytes (P=0.001), neutrophils in squamous mucosa (P<0.001), histiocyte aggregates >15 (P<0.001) and spongiosis (P<0.001). Controls had frequent eosinophils, alone (P=0.008) or admixed with other inflammatory cells (P<0.0001). CONCLUSIONS IHC is used in VE biopsies despite definite viral inclusions on hematoxylin and eosin and in patients without concerning histology or clinical concern for VE. History, endoscopic findings, and histology can be used to better target IHC use in VE.

Abstract
Background and Aim Rhazya stricta is a herbal plant widely used in traditional medicine due to its proficiency and naturalness with few side effects. In this study, we investigated the impact of using an R. stricta extract supplement on broiler chickens' performance, especially the immune system. Materials and Methods In addition to the control group, one group received the methanol extract of R. stricta in drinking water for the first 2 weeks before being challenged with sheep erythrocytes (SRBCs), while the other group was challenged with SRBCs without receiving the R. stricta treatment. We evaluated cellular immunity by determining the phagocytic activity and lymphocyte (L) proliferation and assessed humoral immunity by quantification of the serum total IgM and IgG. We measured the serum levels of antioxidant enzymes and performed a histological examination of the spleen and the bursa of Fabricius (BF). Results Our results indicate a significant enhancement in cellular immunity in the group supplemented with R. stricta as demonstrated by a significant increase in the phagocytic activity, L proliferation, and percentages of circulating L (p<0.05). The chickens treated with R. stricta exhibit an enhanced humoral response shown by a significant elevation in the serum levels of the total antibodies of the IgM and IgG isotypes, along with a notable increase in BF activity. Furthermore, R. stricta supplementation is associated with a significant increase in the serum levels of catalase and superoxide dismutase (p<0.05), along with a significant improvement in broilers' general performance, body weight, and feed efficiency. Conclusion Our results suggest an immunomodulatory effect for the methanol extract of R. stricta and highlight the potential use of this plant in preventive and therapeutic medicine.

Abstract
OBJECTIVES This study aims to improve the diagnosis of gastrointestinal (GI) cytomegalovirus (CMV) disease. It presents the results of a novel study in which CMV blood viral load (BVL), tissue viral load (TVL) determined by PCR and hematoxylin-eosin (HE)/immunohistochemistry (IHC) results of GI biopsies are examined comparatively. METHODS CMV DNA was investigated by quantitative real-time PCR in blood and GI biopsy specimens of 76 patients suspected of CMV disease. Biopsies were also performed HE/IHC stainings in the pathology laboratory. RESULTS This study included 76 patients whose median age was 34.5 years and 58% (44) were male. Tissue CMV PCR positivity was detected in the highest colon (40/53;75.5%) samples. HE, IHC, blood and tissue CMV PCR positivity rates of all samples were 15.8, 25, 50 and 71.1%, respectively. When IHC was used as the gold standard test for ROC analysis, the optimal cutoff values for the maximum sensitivity and specificity for BVL and TVL were 1.91 log10 copies/ml and 3.82 log10 copies/mg, respectively. Sensitivity and specificity for the cutoff value of tissue CMV DNA were 78.9 and 74.3%, respectively (P < 0.001). CONCLUSION In this study, CMV DNA was detected in 71.1% of the tissue samples of the cases by PCR. Since the sensitivity of the histopathological examinations accepted as the gold standard is low, simultaneous with the histopathological examinations, determination of BVL, TVL and the identification of optimal cutoff values have been shown to support the diagnosis of GI CMV disease.
