Abstract
INTRODUCTION Cytomegalovirus (CMV) viral load detected by real-time polymerase chain reaction (PCR) in plasma or stool may facilitate detection of CMV colitis. METHODS This prospective study enrolled 117 patients with clinically suspected CMV colitis. Patients presenting with gastrointestinal symptoms and having increased risk of CMV infection were eligible. All participants underwent colonoscopy with tissue biopsy. Five patients underwent colonoscopy twice because of clinical recurrence, resulting in a total of 122 colonoscopies. Stool CMV-PCR and plasma CMV-PCR were performed within 7 days before/after colonoscopy. Twenty asymptomatic volunteers also underwent the same protocol. RESULTS Twenty-seven (23.1%) of 122 colonoscopies yielded positive for CMV colitis. The sensitivity and specificity was 70.4% and 91.6% for stool CMV-PCR and 66.7% and 94.7% for plasma CMV-PCR, respectively. The sensitivity of either positive plasma or positive stool CMV-PCR was 81.5%, which is significantly higher than that of plasma CMV-PCR alone ( P = 0.045). However, positive results from both tests yielded a specificity of 95.8%, which is significantly higher than that of stool CMV-PCR alone ( P = 0.045). There was a good and significant correlation between stool CMV-PCR and plasma CMV-PCR ( r = 0.71, P < 0.01), and both tests significantly correlated with the cytomegalic cell count ( r = 0.62, P < 0.01 for stool and r = 0.64, P < 0.01 for plasma). There were no positive stool or plasma CMV-PCR assays among volunteers. DISCUSSION The results of this study strongly suggest that the combination of stool CMV-PCR and plasma CMV-PCR can be used to confidently rule in (both positive) or rule out (both negative) a diagnosis of CMV colitis.

Abstract
Cytomegalovirus (CMV) colitis is usually associated with immunosuppressed patients, which by the classic definition are individuals who have immunosuppressed associated conditions (human immunodeficiency virus [HIV], oncology diseases, inflammatory bowel disease, transplant patients) or who are submitted to immunosuppressing therapies (for instance, corticosteroids, chemotherapeutic agents or immunomodulation therapies). In immunocompetent patients, this diagnosis tends to be often missed, leading to a delay in initiating proper management. We present a case of a 91-year-old woman that was diagnosed with CMV colitis without any identified formal immunocompromising factors. We intend to highlight the need to review the definition of an immunosuppressed individual and emphasize that CMV colitis should be considered in the differential diagnosis, especially in elderly patients and those with underlying conditions that can possibly affect their immune status, since prompt diagnosis and treatment are essential and influence the prognosis.

Abstract
Pseudomembranous colitis is severe inflammation of the inner lining of the colon due to anoxia, ischemia, endothelial damage, and toxin production. The majority of cases of pseudomembranous colitis are due to Clostridium difficile. However, other causative pathogens and agents have been responsible for causing a similar pattern of injury to the bowel with the endoscopic appearance of yellow-white plaques and membranes on the mucosal surface of the colon. Common presenting symptoms and signs include crampy abdominal pain, nausea, watery diarrhea that can progress to bloody diarrhea, fever, leukocytosis, and dehydration. Negative testing for Clostridium difficile or failure to improve on treatment should prompt evaluation for other causes of pseudomembranous colitis. Bacterial infections other than Clostridium difficile, Viruses such as cytomegalovirus, parasitic infections, medications, drugs, chemicals, inflammatory diseases, and ischemia are other differential diagnoses to look out for in pseudomembranous colitis. Complications of pseudomembranous colitis include toxic megacolon, hypotension, colonic perforation with peritonitis, and septic shock with organ failure. Early diagnosis and treatment to prevent progression are important. The central perspective of this paper is to provide a concise review of the various etiologies for pseudomembranous colitis and management per prior literature.

Abstract
Purpose Cytomegalovirus (CMV) infection is common in immunocompromised patients. Enterocolitis caused by CMV infection can lead to perforation and bleeding of the gastrointestinal (GI) tract, which requires emergency operation. We investigated the demographics and outcomes of patients who underwent emergency operation for CMV infection of the GI tract. Methods This retrospective study was conducted between January 2010 and December 2020. Patients who underwent emergency GI operation and were diagnosed with CMV infection through a pathologic examination of the surgical specimen were included. The diagnosis was confirmed using immunohistochemical staining and evaluated by experienced pathologists. Results A total of 27 patients who underwent operation for CMV infection were included, 18 of whom were male with a median age of 63 years. Twenty-two patients were in an immunocompromised state. Colon (37.0%) and small bowel (37.0%) were the most infected organs. CMV antigenemia testing was performed in 19 patients; 13 of whom showed positive results. The time to diagnose CMV infection from operation and time to start ganciclovir treatment were median of 9 days. The reoperation rate was 22.2% and perforation was the most common cause of reoperation. In-hospital mortality rate was 25.9%. Conclusion CMV infection in the GI tract causes severe effects, such as hemorrhage or perforation, in immunocompromised patients. When these outcomes are observed in immunocompromised patients, suspicion of CMV infection and further evaluation for CMV detection in tissue specimens is required for proper treatment.

Abstract
Polyarteritis nodosa (PAN) is a rare systemic necrotizing vasculitis affecting small- to medium-sized arteries. The most common gastrointestinal manifestation of PAN is postprandial abdominal pain from mesenteric arteritis causing bowel ischemia. When transmural ischemia develops, there may be ischemic necrosis and perforation of the bowel wall, which are life-threatening. Severe, life-threatening gastrointestinal involvement is relatively rare in pediatric PAN and may require different management in adult patients. We report a pediatric PAN case in a patient who presented with acute abdominal pain and superimposed cytomegalovirus enteritis with jejunoileal perforation. The patient improved with emergency small intestinal resection followed by conventional immunosuppressive drugs of a corticosteroid and cyclophosphamide, and anti-viral drugs. Before increasing the immunosuppressive drug dosage, initial screening of infectious cytomegalovirus and comprehensive evaluation for surgical conditions are essential in pediatric PAN with severe gastrointestinal involvement. Early aggressive treatment for acute abdomen is useful in reducing morbidity and mortality in pediatric PAN.

Abstract
Cytomegalovirus (CMV) esophagitis is the second most common CMV disease of the gastrointestinal tract. This study aims to comprehensively analyze risk factors, clinical characteristics, endoscopic features, outcomes, and prognostic factors of CMV esophagitis. We retrospectively collected data of patients who underwent esophageal CMV immunohistochemistry (IHC) staining between January 2003 and April 2021 from the pathology database at the Chang Gung Memorial Hospital. Patients were divided into the CMV and non-CMV groups according to the IHC staining results. We enrolled 148 patients (44 CMV and 104 non-CMV patients). The risk factors for CMV esophagitis were male sex, immunocompromised status, and critical illness. The major clinical presentations of CMV esophagitis included epigastric pain (40.9%), fever (36.4%), odynophagia (31.8%), dysphagia (29.5%), and gastrointestinal bleeding (29.5%). Multiple diffuse variable esophageal ulcers were the most common endoscopic feature. The CMV group had a significantly higher in-hospital mortality rate (18.2% vs. 0%; p < 0.001), higher overall mortality rate (52.3% vs. 14.4%; p < 0.001), and longer admission duration (median, 24 days (interquartile range (IQR), 11−47 days) vs. 14 days (IQR, 7−24 days); p = 0.015) than the non-CMV group. Acute kidney injury (odds ratio (OR), 174.15; 95% confidence interval (CI), 1.27−23,836.21; p = 0.040) and intensive care unit admission (OR, 26.53; 95% CI 1.06−665.08; p = 0.046) were predictors of in-hospital mortality. In conclusion, the mortality rate of patients with CMV esophagitis was high. Physicians should be aware of the clinical and endoscopic characteristics of CMV esophagitis in high-risk patients for early diagnosis and treatment.

Abstract
Cytomegalovirus (CMV) infection of the gastrointestinal (GI) tract can be fatal. However, very few studies have provided comprehensive analyses and specified the differences in symptoms observed in different parts of the GI tract. This study aimed to comprehensively analyze clinical manifestations and management of GI CMV disease. This retrospective cohort study enrolled the patients who had CMV diseases of the GI tract proved by CMV immunohistochemistry stain from the pathology database in a 4000-bed tertiary medical center between January 2000 and May 2021. The patient characteristics, clinical manifestations, endoscopic features, treatments, outcomes, and prognostic factors were analyzed. A total of 356 patients were enrolled, including 46 infected in the esophagus, 76 in the stomach, 30 in the small intestine, and 204 in the colon. In total, 49.4% patients were immunocompromised. The overall in-hospital mortality rate was 20.8%: CMV enteritis had the highest rate (23.3%). Sixty percent of patients received antiviral treatment and 16% were administered both intravenous and oral anti-viral drugs (Combo therapy, minimal and mean treatment duration were 14 and 39.9 ± 25 days). Prognostic factors of in-hospital mortality included age, immune status, albumin level, platelet count, GI bleeding, time-to-diagnosis, and Combo therapy. In the survival analysis, immunocompetent patients receiving Combo therapy had the best survival curve, and immunocompromised patients receiving non-Combo therapy had the worst survival curve. Combo therapy ≥14 days resulted in a better outcome for both immunocompromised and immunocompetent patients. In conclusion, CMV GI diseases affect both immunocompromised and immunocompetent hosts, and a complete treatment course should be considered for patients with poor prognostic factors.

Abstract
BACKGROUND To comprehensively analyze the risk factors, clinical characteristics, outcomes, and prognostic factors of Cytomegalovirus (CMV) enteritis. METHODS This retrospective cohort study enrolled patients who had undergone pathological examinations for CMV enteritis. They were divided into CMV and non-CMV groups according to immunohistochemistry staining results. The risk factors, clinical presentations, endoscopic features, treatments, outcomes, and prognostic factors of CMV enteritis were then analyzed. RESULTS Forty-two patients (18 CMV, 24 non-CMV group) were included in the study. Major clinical presentations in the CMV group included gastrointestinal bleeding (72.2%), abdominal pain (55.6%), and fever (33.3%); ulcers (72.2%) were the most common endoscopic findings. In-hospital and overall mortality rates were 27.8% and 38.9%, respectively; and longer hospital stays and higher overall mortality rates were observed. Radiotherapy and C-reactive protein levels were prognostic factors for in-hospital mortality. The risk factors for CMV enteritis included immunocompromised status (p = 0.013), steroid use (p = 0.014), shock (p = 0.031), concurrent pneumonia (p = 0.01), antibiotic exposure (p < 0.001), radiotherapy (p = 0.027), chronic kidney disease (p = 0.041), and CMV colitis (p = 0.031). CONCLUSIONS Physicians should pay attention to the characteristics of CMV enteritis in high-risk patients to make an early diagnosis and potentially improve the clinical outcome.

Abstract
Pseudomembranous colitis (PMC) is classically associated with Clostridium difficile infection. We report a rare case of cytomegalovirus (CMV)-associated PMC in a 52-year-old female patient who had undergone kidney transplantation more than 20 years ago and was on low dose prednisolone and ciclosporin. She presented with an acute history of fever, lethargy, vomiting and diarrhoea on admission. Computed tomography of the abdomen showed extensive colitis, and colonoscopy revealed extensive pseudomembrane formation. Multiple tests for Clostridium difficile and other common microbiological causes of colitis were negative. CMV DNAemia and colonic biopsies confirmed the diagnosis of CMV colitis. The patient responded to prompt CMV treatment, as demonstrated by clinical, endoscopic, and histological response. While CMV is a common pathogen in the solid organ transplant population that is familiar to most transplant physicians, it may present atypically as PMC. Here, we review the literature on CMV-associated PMC and its relevance to solid organ transplant recipients. To our knowledge, this is the first reported case of CMV-associated PMC in a kidney transplant recipient.

Yeh PJ, Chiu CT, Lai MW, Wu RC, Kuo CJ, Hsu JT, Su MY, Le PH. Cytomegalovirus gastritis: Clinicopathological profile. Dig Liver Dis 2021; 53:722-728. [PMID: 33441265 DOI: 10.1016/j.dld.2020.12.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 12/02/2020] [Accepted: 12/08/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Cytomegalovirus (CMV) gastritis is occasionally reported in case reports and limited case series. Up to now, it is the largest and most comprehensive retrospective study of CMV gastritis. METHODS All patients who were histologically diagnosed with CMV gastritis at Linkou Chang Gung Memorial Hospital between January 2000 and April 2020 were included. Patients were divided into two groups according to immunity. Between-group differences in characteristics, manifestations, endoscopic features, prognostic factors, and outcomes were analyzed. The main endpoint was 3-month mortality. RESULTS A total of 54 patients (34 immunocompromised, 20 immunocompetent) were enrolled. Common presentations included gastrointestinal bleeding (35.2%), abdominal pain (33.3%) and fever (31.5%). The endoscopic features included ulcer (88.9%) and inflammation (11.1%). The 3-month mortality rate was 20.4% and overall mortality rate was 40.7%. Acute kidney injury was the only independent risk factor for 3-month mortality (OR 53.89, 95%CI 1.56-1861.73, p = 0.027). Anti-viral therapy and host immune status did not affect 3-month mortality. CONCLUSION Both immunocompromised and immunocompetent patients with CMV gastritis have high mortality rates, without significant between-group differences. Acute kidney injury is the only independent predictive factor for 3-month mortality. Prevention of acute kidney injury may possibly improve the 3-month mortality rate.

Clinical Features, Endoscopic Findings, and Predictive Factors for Mortality in Tissue-Invasive Gastrointestinal Cytomegalovirus Disease between Immunocompetent and Immunocompromised Patients. Gastroenterol Res Pract 2021; 2021:8886525. [PMID: 33897776 PMCID: PMC8052155 DOI: 10.1155/2021/8886525] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 03/19/2021] [Accepted: 03/27/2021] [Indexed: 12/26/2022] Open
Abstract
Background and Aims Tissue-invasive gastrointestinal cytomegalovirus (TI-GI CMV) disease is common in immunocompromised patients, but the increasing prevalence in immunocompetent patients has been reported. This study compared the clinical manifestations, endoscopic features, treatment outcomes, and predictors for inhospital mortality of TI-GI CMV between immunocompromised and immunocompetent patients. Methods Patients with HIV infection, malignancy, or receiving immunosuppressive agents (chemotherapy, high dose, or long-term corticosteroids) were defined as the immunocompromised group. Demographic and inhospital mortality data were obtained and retrospectively analyzed. Results A total of 213 patients (89 immunocompetent) with histologically confirmed TI-GI CMV were enrolled. Immunocompetent patients were older (70 vs. 52 years; p < 0.001), had more GI bleeding as a presenting symptom (47.2% vs. 29.0%; p = 0.010), and shorter symptom onset (2 vs. 14 days, p = 0.018). Concomitant extra-GI involvement was only seen in the immunocompromised group (6.5% vs. 0%; p = 0.02). Diffuse GI tract (14.5% vs. 4.5%; p = 0.032) and esophageal involvement (14.5% vs. 5.6%; p = 0.046) were more frequent in the immunocompromised, while small bowel involvement was more frequent in the immunocompetent group (19.1% vs. 8.1%; p = 0.029). An overall inhospital mortality was 27.7%. There was no significant difference in inhospital survival probability between the two groups (Peto-Peto test, p = 0.65). ICU admission (hazard ratio [HR] 7.21; 95% CI 2.55-20.36), sepsis or shock (HR 1.98; 95% CI 1.08-3.66), malnutrition (HR 2.62; 95% CI 1.05-7.01), and receiving chemotherapy (HR 5.2; 95% CI 1.89-14.29) were independent factors for inhospital mortality. Antiviral treatment for more than 14 days was the only protective factor to improve survival (Peto-Peto test, p < 0.001). Conclusions Immunocompetent and immunocompromised patients with TI-GI CMV disease had distinct clinical and endoscopic characteristics. There was no significant difference in the inhospital mortality between the two groups. The factors for mortality were ICU admission, sepsis/shock, malnutrition, and receiving chemotherapy. Early diagnosis and initiation of antiviral treatment might improve the survival probability.

Endoscopic features and clinical outcomes of cytomegalovirus gastroenterocolitis in immunocompetent patients. Sci Rep 2021; 11:6284. [PMID: 33737711 PMCID: PMC7973552 DOI: 10.1038/s41598-021-85845-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 03/05/2021] [Indexed: 01/15/2023] Open
Abstract
We aimed to investigate the endoscopic features and clinical course of CMV gastroenterocolitis in immunocompetent patients. We reviewed the medical records and endoscopic images of 86 immunocompetent patients with CMV gastroenterocolitis. Immunocompetent patients were defined as those without congenital or acquired immunodeficiency syndrome, use of anti-cancer chemotherapeutic and immunosuppressive agents, and inflammatory bowel diseases. The mean age was 65.5 ± 11.8 years and 53 (61.6%) were male. Sixty-eight (79.1%) patients had comorbidities. Upper gastrointestinal-dominant, small bowel-dominant, and colon-dominant types were observed in 19, 7, and 60 patients, respectively. Endoscopic features could be classified into discrete ulcerative type with/without exudate and diffuse erythematous type with/without exudate. Antiviral treatment with ganciclovir was initiated in 51 patients (59.3%), 40 of whom improved and 1 improved after changing ganciclovir to foscarnet. Thirty-three patients (38.4%) improved without antiviral treatment. Surgery was necessary in two patients because of colon perforation before antiviral treatment. Another two patients underwent surgery because of sigmoid stricture and cecal perforation during antiviral treatment. Endoscopic type was not associated with clinical outcomes, such as surgery and death. CMV gastroenterocolitis in immunocompetent patients mostly occur in older patients with comorbidities, and the endoscopic features vary with no association with clinical outcomes.

Abstract
Background Gastrointestinal (GI) cytomegaloviral (CMV) infection is common among patients with immunocompromised status; however, data specific to GI-CMV infection in immunocompetent patients are comparatively limited. Methods This retrospective study included patients diagnosed with GI-CMV infection at Siriraj Hospital (Bangkok, Thailand) during 2008–2017. Baseline characteristics, presentations, comorbid conditions, endoscopic findings, treatments, and outcomes were compared between immunocompetent and immunocompromised. Results One hundred and seventy-three patients (56 immunocompetent, 117 immunocompromised) were included. Immunocompetent patients were significantly older than immunocompromised patients (73 vs. 48.6 years, p < 0.0001). Significantly more immunocompetent patients were in the ICU at the time of diagnosis (21.0% vs. 8.6%, p = 0.024). GI bleeding was the leading presentation in immunocompetent, while diarrhea and abdominal pain were more common in immunocompromised. Blood CMV viral load was negative in significantly more immunocompetent than immunocompromised (40.7% vs. 12.9%, p = 0.002). Ganciclovir was the main treatment in both groups. Significantly more immunocompetent than immunocompromised did not receive any specific therapy (25.5% vs. 4.4%, p ≤ 0.01). Six-month mortality was significantly higher among immunocompetent patients (39.0% vs. 22.0%, p = 0.047). Independent predictors of death were old age and inpatient or ICU clinical setting. Treatment with antiviral agents was the only independent protective factor. Conclusion GI-CMV infection was frequently observed among immunocompetent elderly patients with comorbidities or severe concomitant illnesses. GI bleeding was the most common presentation. Blood CMV viral load was not diagnostically helpful. Significantly higher mortality was observed in immunocompetent than in immunocompromised patients, but this could be due to more severe concomitant illnesses in the immunocompetent group.

CMV Ileitis: To Treat or Not to Treat? Implications of Initiating Biologic Therapy for Concurrent Crohn's Disease. Case Rep Gastrointest Med 2019; 2019:4513795.

Abstract
Cytomegalovirus (CMV) enteritis is traditionally thought to be a self-limited infection in immunocompetent individuals. Consequently, current guidelines recommend against treating nonimmunocompromised patients with antiviral therapy. Conversely, recent data suggests that spontaneous resolution occurs less frequently than previously believed; furthermore, mortality rate in immunocompetent individuals is similar to that of the immunosuppressed. We present a case of a 43-year-old male who was simultaneously diagnosed with CMV ileitis and Crohn's Disease. When discovered concomitantly, there is no guidance in the current medical literature regarding the benefit of antiviral treatment of the CMV infection prior to initiating biologic therapy versus the risks of withholding treatment, as is currently recommended for nonimmunosuppressed individuals.

Cancer Manag Res 2019; 11:759-766.

Abstract
Objective Previous studies showed that the lymph node density (LND) was a predictor of survival in Wilms’ tumor (WT). However, the optimal LND cutoff point is controversial due to methodological shortcomings of previous studies, and no studies have shown the effect of LND on survival in children with WT. The purpose of this study was to remedy this situation. Methods We identified 376 children with WT. LND cutoff point was determined using the median value, the X-tile program, the survival-tree algorithm, and the time-dependent ROC curve analysis. Survival functions were estimated by the Kaplan–Meier method. We used Cox regression analysis to determine the impact of LND on survival. Smooth curve fitting between relative mortality risk and LND was performed. Results The LND cutoff point was 0.44, 0.65, 0.65, and 0.64 according to the median value, the X-tile program, the survival-tree algorithm, and the time-dependent ROC curve analysis, respectively. The 5-, 10-, and 20-year overall survival rates were 86.9%, 86.9%, and 84.7%, respectively, in the <0.44 group and 81.3%, 80.3%, and 80.3%, respectively, in the ≥0.44 group. Survival did not differ significantly between the two groups (P=0.185). The 5-, 10-, and 20-year overall survival rates were 87.8%, 87.8%, and 86.0%, respectively, in the < 0.65 or < 0.64 group and 76.5%, 75.1%, and 75.1%, respectively, in the ≥ 0.65 or ≥ 0.64 group. Children with the high LND had a significantly worse survival (P=0.011) if 0.64 or 0.65 was used for the stratification. LND was a significant predictor for overall survival in the multivariate Cox regression analysis (HR =1.797; 95% CI, 1.043–3.097; P=0.035). Smooth curve fitting suggested that the risk of mortality tended to be ascending with the increase in LND in general. Conclusion The three methods including the X-tile program, the survival-tree algorithm, and the time-dependent receiver operating characteristic (ROC) curve analysis are equivalent in their ability to stratify patients and clearly better than the median method. The results showed that the optimal LND cutoff point was around 0.65 and the LND was a reliable predictor of overall survival in children with WT.
