Acute Fulminant-Onset Synchronized CMV-Ulcerative Colitis.

Arch Iran Med 2019 Feb 1;22(2):99-101. Epub 2019 Feb 1.

Tepecik Education and Research Hospital, Department of Gastroenterology, Yenisehir-Izmir, Turkey.

Cytomegalovirus (CMV) is an agent which exists asymptomatically in most individuals and may cause latent life-time infection following contamination. Symptomatic CMV infection develops most commonly in organ transplant recipients and in individuals who receive immunosuppressive drugs, undergo haemodialysis or have acquired immunodeficiency syndrome. The link between ulcerative colitis and CMV infection and the efficacy of antiviral therapy in these individuals have been demonstrated. Read More

Cytomegalovirus reactivation in inflammatory bowel disease: an uncommon occurrence related to corticosteroid dependence.

Mod Pathol 2019 Apr 5. Epub 2019 Apr 5.

Department of Pathology and Laboratory Medicine, Weill Cornell Medicine, New York, NY, USA.

Cytomegalovirus promotes mucosal injury in patients with inflammatory bowel disease, historically affecting 10-25% of ulcerative colitis patients with refractory disease. Viral reactivation is likely related to long-term corticosteroid therapy, which is no longer central to maintenance of patients with inflammatory bowel disease. We hypothesize that viral detection rates have decreased in the modern era, reflecting widespread use of immunomodulatory agents to control inflammation. Read More

J Clin Neurosci 2019 Apr 1. Epub 2019 Apr 1.

Department of Neurological Surgery, Feinberg School of Medicine, Northwestern University, Chicago, IL 60611, United States; Ken and Ruth Davee Department of Neurology, Feinberg School of Medicine, Northwestern University, Chicago, IL 60611, United States; Robert H. Lurie Comprehensive Cancer Center, Feinberg School of Medicine, Northwestern University, Chicago, IL 60611, United States; Lou and Jean Malnati Brain Tumor Institute, Feinberg School of Medicine, Northwestern University, Chicago, IL 60611, United States. Electronic address:

Survival outcomes for patients with glioblastoma (GBM) are universally poor with only a small percentage of patients surviving five years beyond initial diagnosis. Activation of the immune system against tumor cells is the basis of immunotherapy and aims to facilitate long-term immune surveillance and tumor suppression. Cytomegalovirus (CMV) has emerged as an immunologic target in GBM given that tumor cells have been shown to express the CMV-associated proteins IE1 and pp65. Read More

Nivolumab-induced immune-mediated colitis: an ulcerative colitis look-alike-report of new cases and review of the literature.

Int J Colorectal Dis 2019 May 3;34(5):861-865. Epub 2019 Mar 3.

Gastroenterology Department, Hospital Universitari Germans Trias i Pujol, Carretera del Canyet s/n, 08916, Badalona, Catalonia, Spain.

Purpose: Nivolumab, a monoclonal antibody-targeting programmed cell death protein-1, is being increasingly used for the treatment of some advanced neoplasms. Several of its adverse effects are a result of the upregulation of T cells, with colitis as one of the most severe, and a challenging differential diagnosis with ulcerative colitis. However, few real-life clinical practice cases have been reported beyond trials. Read More

Severe systemic cytomegalovirus infection in an immunocompetent patient outside the intensive care unit: a case report.

BMC Infect Dis 2019 Jan 9;19(1):34. Epub 2019 Jan 9.

Department of Medicine and Surgery, Clinica Medica, University of Milano-Bicocca, San Gerardo Hospital, Via G.B. Pergolesi 33, 20900, Monza, Italy.

Background: Cytomegalovirus is responsible for an opportunistic infection that can be life threatening in immunocompromised patients, while it is usually mild or completely asymptomatic in immunocompetent subjects. In the recent years, however, some cases of severe cytomegalovirus infection in immunocompetent patients have been reported, showing this to be a less rare occurrence than previously reported.

Case Presentation: We report the case of an 83-year-old man, admitted to our hospital for gastroenteritis, complicated by dehydration and severe prothrombin time prolongation due to oral anticoagulant therapy accumulation, who developed hospital-acquired pneumonia; neither of these illnesses responded to several lines of antibiotic therapy.

Department of Radiology, Hospital Garcia de Orta, EPE, Av. Torrado da Silva, Almada 2805-267, Portugal.

Cytomegalovirus (CMV) is the most common cause of severe opportunistic viral disease among patients with acquired immunodeficiency syndrome, and colitis is the most frequent manifestation of CMV infection. Nevertheless, the development of a colonic pseudotumor is a rare benign entity that can be easily misdiagnosed as a colonic neoplasm if the radiologist is not aware of this condition. We present a case of a 42-year-old male with a CMV pseudotumor of the colon. Read More

Fecal transplantation for treatment of inflammatory bowel disease.

Cochrane Database Syst Rev 2018 Nov 13;11:CD012774. Epub 2018 Nov 13.

Department of Pediatrics, Karjoo Family Center for Pediatric Gastroenterology, SUNY Upstate Medical University, 725, Irving Street, Suit 501, Syracuse, NY, USA, 13210.

Background: Inflammatory bowel disease (IBD) is a chronic, relapsing disease of the gastrointestinal tract that is thought to be associated with a complex interplay between microbes and the immune system, leading to an abnormal inflammatory response in genetically susceptible individuals. Dysbiosis, characterized by the alteration of the composition of the resident commensal bacteria in a host compared to healthy individuals, is thought to play a major role in the pathogenesis of ulcerative colitis (UC) and Crohn's disease (CD), two subtypes of IBD. There is growing interest to correct the underlying dysbiosis through the use of fecal microbiota transplantation (FMT) for the treatment of IBD. Read More

Amphiregulin in intestinal acute graft-versus-host disease: a possible diagnostic and prognostic aid.

Mod Pathol 2019 Apr 13;32(4):560-567. Epub 2018 Nov 13.

Hematology, Oncology and Transplant, University of Minnesota, Minneapolis, MN, USA.

Amphiregulin, a weak epidermal growth factor receptor agonist, is elevated, while epidermal growth factor, a strong epidermal growth factor receptor agonist, is low in the blood of patients with severe acute graft-versus-host disease. However, the tissue expression and function of these epidermal growth factor receptor ligands in acute graft-versus-host disease target organs is unknown. We compared by immunohistochemistry expression of amphiregulin and epidermal growth factor in archived, formalin-fixed, paraffin-embedded intestinal tissues of 48 patients with biopsy-proven gastrointestinal acute graft-versus-host disease to 3 groups: (1) 10 non-hematopoietic cell transplant normal controls, (2) 11 patients with newly diagnosed ulcerative colitis (ulcerative colitis), (3) 8 patients with a clinical diagnosis of acute graft-versus-host disease despite pathologically non-diagnostic biopsies, (4) and 10 cases of cytomegalovirus colitis.

Cytomegalovirus pleuropericarditis after orthotopic liver transplantation.

Acta Gastroenterol Belg 2018 Jul-Sep;81(3):427-429

Antwerp University Hospital, Department of Gastroenterology and Hepatology.

Cytomegalovirus (CMV) reactivation is a common complication after liver transplantation. In patients with CMV infection, indicated by a positive CMV DNA titer, the presence of any clinical symptom is termed CMV disease. The most common organ affected in CMV disease is the gastrointestinal tract, causing esophagitis, gastritis, enteritis or colitis. Read More

Prognostic Value of the Burden of Cytomegalovirus Colonic Reactivation Evaluated by Immunohistochemical Staining in Patients with Active Ulcerative Colitis.

J Crohns Colitis 2019 Mar;13(3):385-388

Department of Gastroenterology, Hospital Germans Trias i Pujol, Badalona, Spain.

Background: Colonic cytomegalovirus [CMV] reactivation has been involved in steroid refractoriness in patients with active ulcerative colitis [UC]. The benefits of antiviral therapy in this clinical setting are still under debate, but the burden of viral reactivation has been associated with a poorer outcome in some studies. Our aim was to assess whether the burden of CMV reactivation measured by the number of viral inclusions by immunohistochemistry [IHC-CMV] is associated with a risk of colectomy. Read More

Accuracy of diagnostic tests and a new algorithm for diagnosing cytomegalovirus colitis in inflammatory bowel diseases: a diagnostic study.

Int J Colorectal Dis 2019 Feb 1;34(2):229-237. Epub 2018 Oct 1.

Medizinische Klinik mit Schwerpunkt Gastroenterologie, Infektiologie und Rheumatologie, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Hindenburgdamm 30, 12203, Berlin, Germany.

Purpose: The optimal method for detecting CMV colitis in patients with inflammatory bowel disease (IBD) has not been established. We wanted to investigate which diagnostic test would be most accurate when defining CMV colitis rather by the further clinical course than by using another diagnostic modality.

Methods: All consecutive patients with moderately or severely active IBD who had been tested for CMV by PCR, histology, or antigenemia assay at the two campuses CBF and CCM of the Charité - Universitätsmedizin Berlin between September 2006 and September 2009 were included in this retrospective study.

Apoptotic colopathy: a pragmatic approach to diagnosis.

J Clin Pathol 2018 Dec 1;71(12):1033-1040. Epub 2018 Oct 1.

Department of Pathology, Laboratory Medicine Program, University Health Network, Toronto, Ontario, Canada.

'Apoptotic colopathy' is an umbrella term signifying a pattern of injury where the gastrointestinal biopsy shows a colitic picture with apoptosis as the predominant histological feature. Although the entities within apoptotic colopathy share a common histological feature- 'apoptosis', there is a list of varied clinical differential diagnoses that produce this similar histological pattern of injury. These include graft-versus-host disease, drug-induced injury due to multiple drugs (in particular, mycophenolate mofetil, check point inhibitor therapy and some others), infections (particularly cytomegalovirus, adenovirus and some others), immune disorders and other miscellaneous causes.

Differential diagnosis of inflammatory bowel disease: imitations and complications.

Lancet Gastroenterol Hepatol 2018 09 8;3(9):644-653. Epub 2018 Aug 8.

Department of Gastroenterology and Hepatology, University Hospitals Leuven, Leuven, Belgium. Electronic address:

Inflammatory bowel disease (IBD) is characterised by episodes of relapse and periods of remission. However, the clinical features, such as abdominal pain, diarrhoea, and rectal bleeding, are not specific. Therefore, the differential diagnosis can include a broad spectrum of inflammatory or infectious diseases that mimic IBD, as well as others that might complicate existing IBD. Read More

Fatal disseminated cytomegalovirus infection with necrotizing oophoritis in a patient with acquired immunodeficiency syndrome.

Autops Case Rep 2018 Jul-Sep;8(3):e2018029. Epub 2018 Jul 30.

Universidade de São Paulo, Faculty of Medicine, Department of Anatomic Pathology, Emergency Department and LIM06. São Paulo, SP, Brazil.

Disseminated human cytomegalovirus (CMV) disease occurs mainly as a congenital infection and among immunocompromised hosts. Patients with acquired immunodeficiency syndrome (AIDS) are at increased risk for CMV infection, and the most prevalent clinical manifestation is retinitis, followed by colitis, esophagitis, pneumonitis, and encephalitis. CMV oophoritis is poorly described in the literature with some cases reported in patients with hematological or solid malignancies, bone marrow or solid organ transplantation, immunosuppressive therapy, and advanced AIDS cases.

Fecal microbiota transplantation for the treatment of recurrent and severe Clostridium difficile infection in solid organ transplant recipients: A multicenter experience.

Am J Transplant 2019 Feb 31;19(2):501-511. Epub 2018 Aug 31.

Division of Gastroenterology, Department of Medicine, Indiana University School of Medicine, Indianapolis, IN, USA.

Fecal microbiota transplant (FMT) is recommended for Clostridium difficile infection (CDI) treatment; however, use in solid organ transplantation (SOT) patients has theoretical safety concerns. This multicenter, retrospective study evaluated FMT safety, effectiveness, and risk factors for failure in SOT patients. Primary cure and overall cure were defined as resolution of diarrhea or negative C difficile stool test after a single FMT or after subsequent FMT(s) ± anti-CDI antibiotics, respectively. Read More

Cytomegalovirus promotes intestinal macrophage-mediated mucosal inflammation through induction of Smad7.

Mucosal Immunol 2018 11 3;11(6):1694-1704. Epub 2018 Aug 3.

Departments of Medicine (Gastroenterology), University of Alabama, Birmingham, Alabama, 35294, USA.

Intestinal macrophages in healthy human mucosa are profoundly down-regulated for inflammatory responses (inflammation anergy) due to stromal TGF-β inactivation of NF-κB. Paradoxically, in cytomegalovirus (CMV) intestinal inflammatory disease, one of the most common manifestations of opportunistic CMV infection, intestinal macrophages mediate severe mucosal inflammation. Here we investigated the mechanism whereby CMV infection promotes macrophage-mediated mucosal inflammation. Read More

Bone marrow transplant-associated thrombotic microangiopathy without peripheral blood schistocytes: a case report and review of the literature.

Exp Hematol Oncol 2018 22;7:14. Epub 2018 Jun 22.

3Cedars-Sinai Medical Center, Los Angeles, CA USA.

Background: Bone marrow transplant-associated thrombotic microangiopathy (TA-TMA) is a relatively frequent but under-recognized and under-treated hematopoietic stem cell transplant (HSCT) complication that leads to significant post-transplant morbidity and mortality. Classic TMA-defining laboratory abnormalities appear at different times in the course of TA-TMA development, with schistocytes often appearing later in the disease course. In some severe TMA cases, schistocytes may be absent due to increased endothelial permeability. Read More
