Background: Antibodies against tumor necrosis factor alpha (anti-TNF-α) are currently widely used in the treatment of inflammatory bowel diseases (IBD), despite a number of reported adverse effects. Diverse neurologic syndromes, including the Guillain-Barré syndrome (GBS), an immune-mediated disease characterized by evolving ascending limb weakness, sensory loss, and areflexia, have been described in association with anti-TNF-α therapy. Case Report: A 45-year-old White woman was in follow-up with fistulizing ileocolonic Crohn disease using combination therapy (infliximab plus azathioprine) as CD maintenance therapy. After 3 years of this immunosuppressive therapy, she presented with symmetrical and ascending paresis in the lower limbs, and later in the upper limbs, in addition to reduced reflexes in the knees, 1 day after an infliximab infusion. The patient was hospitalized and treatment for CD was suspended. Neurophysiology studies demonstrated a pattern compatible with acute inflammatory demyelinating polyradiculopathy, with predominantly motor involvement, consistent with Guillain-Barré syndrome (GBS). Clinical, laboratory, and imaging exams were unremarkable. She was treated with intravenous immunoglobulins, with a progressive and complete resolution of neurological symptoms. After 1-year follow-up, she presented with active Crohn disease, and we opted for treating her with vedolizumab, with which she achieved clinical and endoscopic remission. Conclusions: Patients receiving biological therapy with anti-TNF-α agents should be monitored for central or peripheral neurological signs and symptoms. The development of GBS can be secondary to anti-TNF-α treatment. The positive temporal relationship with TNF-α therapy and onset of neurological symptoms reinforces this possibility.

Objective: Unusual clinical course Background: Infliximab, a monoclonal antibody against tumor necrosis factor (TNF) alpha with proven efficacy and known safety profile, is currently widely used in the treatment of inflammatory bowel diseases. Increased risk for serious infections and malignant neoplasms secondary to immunosuppression is a major concern during therapy with this medication. Histoplasmosis is a granulomatous disease caused by the fungus Histoplasma capsulatum. Disseminated forms of the disease have immunodepression as a major risk factor. Case Report: A 39-years-old man had been followed with refractory fistulizing ileocolonic Crohn's disease using combination therapy (infliximab plus azathioprine) and also receiving short courses of steroids. After 2 years of this immunosuppressive therapy, the patient presented with high fever (39.5°C) for 5 days, associated with profuse sweating, and moderate pain in the left hypochondrium. The patient was hospitalized. Diagnoses of tuberculosis, malignancy, autoimmune diseases, and bacterial and viral infections were rapidly discarded after investigation. Clinical, laboratory, and image signs of liver involvement prompted a guided percutaneous biopsy, which revealed granulomatous hepatitis, with the presence of fungal structures suggestive of Histoplasma capsulatum. Upon treatment with liposomal amphotericin followed by itraconazole, the patient showed an impressively positive clinical response. Conclusions: TNF blockers, particularly when associated with other immunosuppressors, are a serious risk factor for opportunistic infections. This unusual case of disseminated histoplasmosis in a patient with Crohn's disease using infliximab in combination with azathioprine and steroids emphasizes the need for surveillance of this uncommon but potentially lethal complication before starting TNF blockers therapy.

Background COVID-19 has affected the entire world. We aimed to determine the impact of COVID-19 containment measures on the daily life and follow up of patients with inflammatory bowel disease (IBD). Methods During May 2020, we evaluated 179 (79.6%) patients with Crohn’s disease (CD) and 46 (20.4%) with ulcerative colitis (UC) by telephone, using a structured questionnaire to gather information on social impact and IBD follow up. Results Some kind of social distancing measure was reported by 95.6% of our patients, selfquarantine (64.9%) being the most frequent. Depressive mood was the most prevalent social impact (80.2%), followed by anxiety/fear of death (58.2%), insomnia (51.4%), daily activity impairment (48%), sexual dysfunction (46.2%), and productivity impairment (44%). The results were similar when we compared patients with active disease to those in remission and patients with UC to those with CD. Analysis of IBD follow up showed that 83.1% of all patients missed an IBD medical appointment, 45.5% of the patients missed laboratory tests, 41.3% missed the national flu vaccination program, 31.3% missed any radiologic exam, 17.3% missed colonoscopy, and 16.9% failed to obtain biologic therapy prescriptions. Biologics were discontinued by 28.4% of the patients. UC patients had higher rates of missed vaccination than CD patients (56.5% vs. 37.4%, P=0.02) and more failures to obtain a biologic prescription (28.3% vs. 14.0%, P=0.02). Conclusions Our study reveals alarming social impacts and declining follow-up care for IBD patients during the COVID-19 outbreak. These findings may have implications for disease control in the near future. [ABSTRACT FROM AUTHOR]
