Colitis and Intestinal Granulomas in Acquired Immunodeficiency Syndrome.

Clin J Gastroenterol 2022 Jun 8. Epub 2022 Jun 8.

Division of Gastroenterology-Hepatology, Department of Medicine, University of Connecticut Health Center, Farmington, CT, 06030, USA.

Granulomas consist of focal collections of immune cells that forms as a result of chronic inflammation. They can be formed in different organs and are considered the hallmark for several inflammatory and infectious diseases. The presence of granulomas in the mucosal biopsies of the gastrointestinal (GI) tract of immunocompetent patients, along with histological features of chronicity, confirms the diagnosis of Crohn's disease (CD) in the majority of cases.

Isolated Gastritis Secondary to Immune Checkpoint Inhibitors Complicated by Superimposed Cytomegalovirus Infection.

ACG Case Rep J 2022 Feb 23;9(2):e00747. Epub 2022 Feb 23.

Division of Gastroenterology and Hepatology, Department of Medicine, University of Maryland School of Medicine, Baltimore, MD.

Immune checkpoint inhibitors such as nivolumab increase the T-cell destruction of malignancies but can also trigger a broad variety of immune-related adverse events (irAEs). Colitis as an irAE is well-documented, but upper gastrointestinal tract involvement is primarily unrecognized. We present a patient who developed gastritis as an irAE after multiple cycles of nivolumab and initially responded well to steroid therapy but then developed superimposed cytomegalovirus infection.

Viral enteric infections in acute severe ulcerative colitis.

J Crohns Colitis 2022 Feb 15. Epub 2022 Feb 15.

Royal Brisbane and Women's Hospital.

Background And Aims: Excluding superimposed enteric infection is critical in acute severe ulcerative colitis management. Whilst infection with Clostridium difficile and cytomegalovirus have been shown to increase colectomy and mortality rates, no data exists regarding the impact of common viral enteropathogens in acute severe ulcerative colitis. Our aim was to determine if viral enteric infection in acute severe ulcerative colitis alters the severity or outcomes of these episodes. Read More

Colitis due to Cytomegalovirus and Herpes Simplex Type 2 as a Complication of a First Presentation of Inflammatory Bowel Disease.

GE Port J Gastroenterol 2022 Jan 23;29(1):56-60. Epub 2021 Mar 23.

Department of Gastroenterology, Hospital de Braga, Braga, Portugal.

Introduction: The first presentation of ulcerative colitis may be an acute flare in about 15% of patients, requiring hospital admission. In acute severe steroid-refractory ulcerative colitis, cytomegalovirus (CMV) should be sought because it is a frequent cause of refractory disease. Herpes simplex colitis constitutes a rarer event in ulcerative colitis patients and it is usually associated with immunosuppression. Read More

SARS-CoV-2 (COVID-19) pneumonia patient treated with two doses of infliximab within 2 weeks for acute severe ulcerative colitis: A case report.

Medicine (Baltimore) 2022 Jan;101(4):e28722

Gastroenterology Department of Damascus Hospital, Damascus, Syria.

Rationale: The ongoing coronavirus pandemic has caused severe acute respiratory syndrome, posing a significant challenge for patients receiving immunotherapy for immune-mediated inflammatory diseases. As of January 2022, immunosuppressants such as tumor necrosis factor inhibitors (anti-TNFα) and azathioprine are inadvisable for an infectious disease caused by the SARS-CoV-2 virus (COVID-19). We continued infliximab as a second induction dose nine days after the onset of COVID-19 symptoms in a patient with acute severe ulcerative colitis. Read More

Cytomegalovirus in ulcerative colitis: an evidence-based approach to diagnosis and treatment.

Expert Rev Gastroenterol Hepatol 2022 Feb 31;16(2):109-120. Epub 2022 Jan 31.

Department of Gastroenterology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Introduction: The detection of cytomegalovirus (CMV) in the setting of inflammatory bowel disease often creates confusion whether CMV is a 'bystander' or 'disease.'

Areas Covered: This review discusses the clinical conundrum of CMV in ulcerative colitis, approach to discriminate infection from disease, and therapeutic considerations (immunosuppressive and anti-CMV treatment). CMV disease should be considered in corticosteroid refractory- dependent and thiopurine refractory disease. Read More

Gastrointestinal Complications after Allogeneic Hematopoietic Stem Cell Transplant: A Multidisciplinary Approach with Early Endoscopic Evaluation.

Clin Hematol Int 2021 Dec 23;3(4):161-168. Epub 2021 Sep 23.

Clinica Ematologica, Dipartimento di Medicina Interna, Ospedali Riuniti Ancona, Italy.

Gastrointestinal complications (GICs) represent the major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Differential diagnosis of GICs is of paramount importance since early and reliable identification of graft-versus-host disease (GVHD) is essential for a correct management of the patients. The aim of the present retrospective study was to evaluate the occurrence of GICs after allo-HSCT and to assess the diagnostic performance of a quick endoscopic and histological assessment in the differential diagnosis between GVHD and other GI conditions.
