Abstract
BACKGROUND Cytomegalovirus (CMV) infection, often subclinical in childhood, is reactivated during a state of cell-mediated immunodeficiency. In cases of organ damage, patients can require medical treatment for an infectious disease, generally through the use of antiviral drugs. There are no reports of surgical treatment in cases, where infection was found, and medical treatment was difficult. We encountered a case of CMV enteritis that was difficult to treat because of resistance to antivirals but improved after total colectomy. CASE PRESENTATION A previously healthy, 74-year-old woman visited a doctor with a chief complaint of watery diarrhea persisting for 2 weeks; she was transferred to our hospital because of hypoxemia and hypovolemic shock. Computed tomography scan indicated wall thickening over the entire colon and the patient was diagnosed with infectious colitis. Conservative and antibacterial therapies were started with fasting fluid replacement. Subsequently, bloody stools were observed 11 days after admission. Colonoscopy was then performed, which showed mucosal edema and longitudinal ulcer, while a histopathological examination of the colon mucosa revealed C7HRP positive on 22 days after admission. CMV enteritis was diagnosed, and the antiviral medication, ganciclovir, was started. Diseases causing immunosuppression and other possible causes of enteritis were also closely examined; however, all were negative. Furthermore, the patient's symptoms and her endoscopic findings did not improve with ganciclovir administration; therefore, the antiviral drug was changed to foscarnet. Unfortunately, the patient did not improve despite the additional administration of gamma globulin and methylprednisolone, and she was determined to have enteritis resistant to medical therapy. A total colon resection was performed 88 days after the admission. Her condition gradually stabilized postoperatively, and oral intake was initiated and tolerated. The patient was transferred to another hospital for rehabilitation for home discharge. She is now at home and has had no recurrences. CONCLUSIONS In previous reports of surgical treatment for CMV enteritis, many cases were initially undiagnosed, emergency surgery was performed after perforation or stenosis was recognized, and then CMV was diagnosed and treated. In CMV enteritis without immunodeficiency, surgical treatment may be an option if medical treatment is ineffective.

Patient characteristics, clinical manifestations, prognosis, and factors associated with gastrointestinal cytomegalovirus infection in immunocompetent patients. BMC Gastroenterol 2020; 20:22. [PMID: 32000707 PMCID: PMC6990526 DOI: 10.1186/s12876-020-1174-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Accepted: 01/19/2020] [Indexed: 12/20/2022] Open
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.

Abstract
Cytomegalovirus (CMV) typically causes gastrointestinal infections in immunocompetent patients. Colonic perforations secondary to CMV are exceeding rare. We describe a 88-year-old male presenting with a week-long history of intractable abdominal discomfort, bloating, nausea and diarrhea. Flexible sigmoidoscopy revealed significant ulceration with yellowish slough. Emergency surgery was performed subsequently in view of multiple perforations in the rectosigmoid junction. CMV gastrointestinal infections demonstrated an ischemic process secondary to vasculitis, which accelerated the pathway to colonic perforation. CMV gastrointestinal infection should be considered as a differential diagnosis in patients with colonoscopy findings similar to ischemic colitis and Clostridium difficile infections.

Abstract
The incidence of atherosclerotic mesenteric ischemia increases gradually with the aging of the population and rising of the incidence of atherosclerosis. In the last decade, mesenteric atherosclerosis has become the most common cause of acute and chronic mesenteric ischemia. Atherosclerotic mesenteric ischemia often presents with an insidious onset and slow evolvement, and is easily overlooked. The CT manifestations of advanced mesenteric ischemia are classic with high diagnostic accuracy, and the specific findings of CT angiography include: thromboembolus and stenotic or occlusive mesenteric artery in acute stage, single or multiple calcified or non-calcified plaques, and multiple stenotic and stiff mesenteric arteries with reduced branching vessels in chronic stage. Early mesenteric ischemia, however, has no or nonspecific CT sign and is difficult to detect. This article discusses the diagnostic value and limitations of multi-slice CT in atherosclerotic mesenteric ischemia as well as some new imaging techniques for diagnosis of this condition.

Abstract
PURPOSE OF REVIEW To provide an update on the epidemiology, pathophysiology, clinical presentation, and management of colonic ischemia. RECENT FINDINGS Formerly regarded as a rare cause of lower gastrointestinal hemorrhage, colonic ischemia is now recognized to be the most common manifestation of intestinal vascular compromise. In contrast to ischemic events in the small intestine wherein thrombotic and embolic events predominate, colonic ischemia typically results from a global reduction in blood flow to the colon and no occlusive lesion(s) are evident. Several risk factors for colonic ischemia have been identified and, together with an appropriate clinical presentation and patient demographics, create a context in which the clinician should have a high level of suspicion for its presence. Imaging with computerized tomography, in particular, may be highly supportive of the diagnosis, which where appropriate can be confirmed by colonoscopy and colonic biopsy. For most patients, management is supportive and noninterventional, and the prognosis for recurrence and survival are excellent. SUMMARY Colonic ischemia is a common cause of lower abdominal pain and hemorrhage among the elderly typically occurring in the aftermath of an event which led to hypoperfusion of the colon. For most affected individuals the ischemia is reversible and clinical course benign.

Abstract
INTRODUCTION Cytomegalovirus (CMV) is known to be opportunistic in immunocompromised patients. However, there have been emerging cases of severe CMV infections found in immunocompetent patients. Gastrointestinal (GI) CMV disease is the most common manifestation affecting immunocompetent patients, with duodenal involvement being exceedingly rare. Presented is a case of an immunocompetent patient with life-threatening bleeding caused by CMV duodenitis, requiring surgical intervention. PRESENTATION OF CASE A 60-year-old male with history of disseminated Methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia and aortic valve infective endocarditis, presented with life-threatening upper GI hemorrhage. Endoscopy revealed ulcerations, with associated generalized mucosal bleeding in the duodenum. After repeated endoscopic therapies and failed interventional-radiology arterial embolization, the patient required a duodenectomy and associated total pancreatectomy, to control the duodenal hemorrhage. Pathologic review of the surgical specimen demonstrated CMV duodenitis. Systemic ganciclovir was utilized postoperatively. DISCUSSION GI CMV infections should be on the differential diagnosis of immunocompetent patients presenting with uncontrollable GI bleeding, especially in critically ill patients due to transiently suppressed immunity. Endoscopic and histopathological examinations are often required for diagnosis. Ganciclovir is first-line treatment. Surgical intervention may be considered if there is recurrent bleeding and CMV duodenitis is suspected because of high potential for bleeding-associated mortality. CONCLUSION Presented is a rare case of life-threatening GI hemorrhage caused by CMV duodenitis in an immunocompetent patient. The patient failed endoscopic and interventional-radiology treatment options, and ultimately stabilized after surgical intervention.

Abstract
Acute mesenteric ischemia (AMI) has an acute onset and a high mortality rate with nonspecific clinical presentation and is difficult to diagnose. In recent years, due to fast submillimeter scanning and subtle three-dimensional reconstruction, 64-row multi-slice CT can distinctly demonstrate the stenosis and occlusion of the mesenteric vessels, assess the alteration of morphology and blood perfusion of the intestinal wall and mesentery, and promptly and accurately diagnose AMI, intestinal infarction and its etiology. Therefore, CT has become the most valuable and first-line diagnostic modality for evaluating patients with suspected AMI. AMI has different and complicated CT findings due to different etiology, pathology, extent, position, as well as with or without mural hemorrhage or infection. In this article, we systematically review the multi-slice CT manifestations of AMI and its diagnostic value in various causes of AMI in different stages.

Abstract
When we examine a patient with symptoms of acute enteritis in the course of chemotherapy with oral fluoropyrimidines such as uracil-tegafur (often referred to as UFT), we usually suspect 5-fluorouracil-induced enterocolitis. In case of persistent clinical symptoms despite discontinuation of chemotherapy, cytomegalovirus colitis should be considered in the differential diagnosis of chemotherapy-induced enterocolitis. We herein report the case of a patient who underwent surgery for lung adenocarcinoma followed by postoperative adjuvant chemotherapy with uracil-tegafur and was diagnosed as having cytomegalovirus colitis during the therapy. In the course of chemotherapy, cytomegalovirus colitis occasionally occurs even though the patient does not experience severe myelosuppression; thus, it is necessary that we recognize its potential occurrence.

Abstract
CMV infections are generally thought to be opportunistic by immunosuppression. Many literature cases though indicate that CMV infections can be also observed in immunocompetent patients. We present an unusual case of an extensive concentric benign stenosis due to CMV colitis and a case of coexistence with Crohn's Disease, both observed in nonimmunosuppressed individuals. The right diagnosis was set after implementation of multiple unsuccessful treatment strategies. Our purpose is therefore to familiarize clinicians involved with the diagnosis and treatment of gastroenterological diseases with this entity.
