Cytomegalovirus (CMV) reactivation is common in patients with severe ulcerative colitis (UC), and may ref lect exacerbation of mucosal inf lammation and/or administration of immunosuppressants. The question of whether CMV is an active pathogen or 'an innocent bystander' in the exacerbation of UC remains controversial. Patients with UC exacerbated by reactivated CMV experience worse prognoses than those without CMV reactivation and antiviral therapy significantly reduces the need for colectomy in patients with severe UC and high-grade CMV infection, indicating that CMV plays a role in UC prognosis...

We report the case of a patient with acute necrotizing colitis due to invasive amebiasis associated with CD4 lymphopenia and impaired neutrophil responses. The course of the disease was characterized by CMV reactivation and severe and recurrent bacterial and fungal infections, which might be related to the decreased CD4 T cell count and the impaired functional capacities of neutrophils, respectively. The clinical outcome was positive with normalization of both CD4 cell count and neutrophil functions.

Although severe flare of ulcerative colitis (UC) is uncommon, it significantly increases the risk of preterm delivery, low birth weight and other adverse fetal outcomes. It is critical to optimize aggressive medical treatment with both mother and fetal health. Here, we present a case of a 30-year-old woman with a severe flare of UC at the 16th gestational week. The diagnosis of extensive UC was established 8 years ago. From the time she was diagnosed, she had 5 moderate flares successfully treated with oral and topical mesalamine...

We report a case of HIV-associated Cytomegalovirus colitis complicated by large bowel perforation. A 62-year-old man of same-sex relationship was not known to have HIV, but a diagnosis of inflammatory bowel disease was made early in his admission, with steroid treatment initiated. He was later confirmed to be HIV positive, and found to have multiple microperforations of the bowel necessitating ileocecectomy and Hartmann's procedures.

BACKGROUND: Cytomegalovirus (CMV) infection among HIV-infected individuals may cause end-organ disease, which is an AIDS-defining condition. Evidence from high-income countries suggests that CMV may alter the outcome of HIV infection, other than causing end-organ diseases. We reviewed literature on HIV and CMV coinfection in Africa. METHODS: Systematic review of published studies on HIV and CMV coinfection in Africa using the PubMed database. RESULTS: High CMV seroprevalence was found throughout Africa, exceeding 90% in most populations...

BACKGROUND: New treatments are needed as Clostridium difficile infection (CDI) is becoming increasingly formidable. Fecal microbiota transplantation (FMT) has a 90% success rate in the treatment of recurrent CDI. However, evidence regarding its safety, efficacy, and effect on disease activity in patients with inflammatory bowel disease (IBD) is lacking. METHODS: This cohort study used data from 8 national and international academic centers. Patients with established IBD who underwent FMT for recurrent CDI were followed for a minimum of 3 months...

BACKGROUND: Cytomegalovirus (CMV)-seronegative kidney transplant (KTx) recipients of organs from CMV-seropositive donors (D+/R-) are at increased risk for CMV infection. Despite valganciclovir (VGCV) prophylaxis (900 mg daily for 200 days), late-onset CMV (LO-CMV) occurs at excessive rates. VGCV-associated cost and toxicities remain problematic. METHODS: We retrospectively evaluated 50 D+/R- adult KTx recipients from August 2008 to August 2014 who received low-dose VGCV (450 mg daily) prophylaxis for an extended duration...

Immune-related adverse events (irAEs) induced by checkpoint inhibitors are well known. Since fatal outcomes have been reported early detection and adequate management are crucial. In particular, colitis is frequently observed and can result in intestinal perforation. This is the first report of an autoimmune colitis that was treated according to algorithms but became resistant due to a CMV reactivation. The 32-y-old male patient with metastatic melanoma treated within an anti-PD-1/ipilimumab combination study developed severe immune-mediated colitis (CTCAE grade 3) with up to 18 watery stools per day starting 2 weeks after treatment initiation...

The tyrosine kinase inhibitor dasatinib is often used after allogeneic hematopoietic cell transplantation to treat minimal residual disease in Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). Colitis, sometimes hemorrhagic, has occasionally been described with the use of dasatinib for both chronic myeloid leukemia and Ph+ ALL. The pathogenesis of dasatinib-induced colitis is unclear but may be related to effects of dasatinib on immune function. We describe a series of 5 patients who had 7 episodes of colitis during dasatinib use...
