    Abstract Frequently used in the management of hypertension and heart failure, hydralazine is associated with the development of adverse rheumatologic side effects. The authors highlight a unique case of drug-induced lupus and drug-induced anti-neutrophil cytoplasmic antibody (ANCA) vasculitis from hydralazine use in a 50-year-old man with sarcoidosis and hypertension.

    Abstract Background: With advent of direct-acting antiviral agents (DAA), hepatitis C virus (HCV) treatment is dramatically increasing. Although few studies reported rates of hepatocellular carcinoma (HCC) recurrence following DAA treatment, there have been no studies that followed sufficient number of DAA-treated patients after successful HCC treatment to examine HCC recurrence.
    Methods: We conducted a cohort study of HCV+ patients who had successfully treated HCC before initiating DAAs. We conducted medical record reviews to confirm HCC diagnosis, treatment, and remission prior to DAA initiation, and subsequent HCC recurrence. We calculated HCC recurrence rate and examined the recurrent tumor characteristics. We used Cox proportional hazard model to identify factors associated with HCC recurrence.
    Results: We identified 264 HCV+ patients who received DAAs after an average of 30.9 (20.6) months following HCC treatment. HCC recurred in 26.1% patients during 23.3 (9.8) months follow-up, at a rate of 0.38 [0.30, 0.48] per 1000 person-month. Most (82.3%) recurrent HCC were early stage. Receiving non-curative treatment for HCC was associated with a higher risk of recurrence than curative treatment (HR
    Conclusions: We conclude that most HCV+ patients with HCC benefit from DAA treatment; however, timing of DAA initiation after HCC treatment should be carefully considered.

    Abstract Background: Microscopic colitis (MC) has been described as 1 pattern of injury in immune checkpoint inhibitor (ICPI)-induced colitis. The main objective of this study was to characterize ICPI-induced MC by exploring the differences in risk factors, colitis treatments, endoscopic features, and clinical outcomes between cancer and noncancer patients with MC with and without exposure to ICPIs.
    Methods: A retrospective chart review was conducted among patients diagnosed with MC from our institutional pathology database from January 2012 to January 2018. Patients were categorized into MC in cancer patients with or without ICPI exposure and in noncancer patients. Risk factors (use of tobacco and certain medications), colitis treatments (antidiarrheals and immunosuppressants), endoscopic features (with or without mucosal abnormality), and clinical outcomes (diarrhea recurrence, hospitalization, mortality) were collected and compared among the 3 groups.
    Results: Of the 65 eligible patients with MC, 15 cancer patients had exposure to ICPI, 39 cancer patients had no exposure to ICPI, and 11 had no cancer diagnosis. Among the risk factors, proton pump inhibitor was more frequently used in the ICPI-induced MC cohort (P = 0.040). Furthermore, in this population, mucosal abnormality was the most common endoscopic feature compared with normal findings in the non-ICPI-induced MC groups (P = 0.106). Patients with ICPI-induced MC required more treatments with oral and intravenous steroids and nonsteroidal immunosuppressive agents (all P < 0.001) and had a higher rate of hospitalization (P < 0.001).
    Conclusion: This study suggests that despite some similarities between MC with and without exposure to ICPIs, ICPI-induced MC has a more aggressive disease course that requires more potent immunosuppressive treatment regimens and greater need for hospitalization. 10.1093/ibd/izy240_video1izy240.video15828223597001.

    Abstract Background: Cancer patients are susceptible to recurrent Clostridium difficile infection (CDI) that is increasing globally, necessitating new approaches to prevent fatal consequences. We examined the clinical characteristics of cancer patients with recurrent CDI (RCDI).
    Patients and methods: A retrospective review of cancer patients with C. difficile-positive test between January 2015 and May 2017 was carried out. CDI was defined as diarrhea and toxigenic C. difficile detection in the stool by nucleic acid amplification test and enzyme immunoassay. Patients having two CDI episodes were categorized as single recurrent CDI (SRCDI), and those having three or more CDI episodes were categorized as multiple recurrent CDI (MRCDI). Treatment failure was defined as the requirement of antimicrobial alteration or repetition.
    Results: We included 170 patients having 270 CDI episodes; 85 patients had non-RCDI, and 85 had RCDI; 14 of them had MRCDI. Previous hospitalization and immunosuppressant use were more frequent in MRCDI group than in SRCDI group (P=0.009 and 0.002, respectively). Physicians treated more SRCDI episodes than MRCDI episodes with metronidazole alone (P=0.017), whereas, more MRCDI episodes needed combination antimicrobials (P=0.072). The mean duration of CDI treatment was longer in the MRCDI group than in the SRCDI group (P=0.030). MRCDI was associated with treatment failure more than SRCDI (P=0.021). The risk for a recurrent episode of CDI was increased in patients who had the following features of the first CDI episode: previous use of antibiotic, NSAID, immunosuppressant, chemotherapy, comorbidities, CDI treatment failure, and severe CDI (P<0.05).
    Conclusion: Risk factors for RCDI in cancer patients are similar to those without cancer, with the exception of chemotherapy that is only given to cancer patients. Long CDI treatment and CDI treatment failure are associated with MRCDI.

    Abstract We report the first case series of immune checkpoint inhibitors (ICI)-associated colitis successfully treated with fecal microbiota transplantation, with reconstitution of the gut microbiome and a relative increase in the proportion of regulatory T-cells within the colonic mucosa. These preliminary data provide evidence that modulation of the gut microbiome may abrogate ICI-associated colitis.
