Fecal Microbiota Transplantation for Clostridioides Difficile Infection in Patients with Chronic Liver Disease.

BACKGROUND: Fecal microbiota transplantation (FMT) is a well-established therapeutic option for patients with antibiotic resistant Clostridioides difficile infection (CDI). However, the efficacy of FMT in patients with chronic liver disease remains elusive. AIMS: We studied the effect of FMT on chronic liver disease (CLD) patients with CDI at our tertiary medical center. METHODS: A cohort of all patients who received FMT from December 2012 to May 2014 for refractory or recurrent CDI was identified. Patients were monitored for a year after FMT. Descriptive analysis was conducted to compare the effect of FMT in patients with and without CLD. RESULTS: A total of 201 patients with CDI received FMT, 14 of which had a history of CLD. Nine of these patients exhibited cirrhosis of the liver with a mean Child-Turcotte-Pugh score of 8. CDI development in these patients was associated with recent exposure to antibiotics and was observed to be significantly different between both groups (17% of CLD patients vs. 58% in the general cohort, p = 0.01). Four patients with CLD received >1 FMT, of which 2 did not respond to treatment. There was no significant difference between patients with liver disease and the rest of the cohort with regard to FMT response (12/14 (87%) vs. 164/187 (88%), p = 0.01). Four patients with CLD received >1 FMT, of which 2 did not respond to treatment. There was no significant difference between patients with liver disease and the rest of the cohort with regard to FMT response (12/14 (87%) vs. 164/187 (88%). CONCLUSION: FMT is a safe and effective therapy against CDI for patients with CLD and cirrhosis.

Hepatitis C Virus-Associated Aortitis Caused by Type I Cryoglobulins.

Chronic hepatitis C virus infection (HCV) can present with cryoglobulinemic vasculitis, which is primarily associated with type II/III cryoglobulins. Type I cryoglobulins are usually seen in lymphoproliferative disease, and large vessel involvement with this type of vasculitis is rare. A 70-year-old man with chronic HCV presented with abdominal pain, leukocytosis, and rash. Computed tomography angiography showed thickening of the abdominal aorta consistent with large-vessel vasculitis. He was found to have type I cryoglobulinemia and was treated with corticosteroids and ledipasvir/sofosbuvir with rapid resolution of his aortitis. This case emphasizes the need to recognize HCV as a potential etiology of large-vessel vasculitis.

Outcomes of Fecal Microbiota Transplantation for Clostridium difficile Infection in Patients with Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Fecal microbiota transplantation (FMT) has recently been shown to be a promising therapy for recurrent and refractory Clostridium difficile infections (CDI) despite lack of protocol standardization. Patients with inflammatory bowel disease (IBD) present a particular challenge to CDI therapy as they are reported to have worse clinical outcomes, including higher colectomy rates and increased mortality. We aimed to assess the outcomes of FMT for recurrent CDI in patients with IBD at our healthcare system. METHODS: We constructed a retrospective cohort of all patients who underwent FMT at our healthcare system between December 2012 and May 2014. Patients with concurrent IBD were identified. We evaluated the differences in demographic and clinical characteristics, along with the outcomes to FMT between patients with IBD as compared to the general population. RESULTS: Over the study period, 201 patients underwent FMT of which 20 patients had concurrent IBD. Patients with IBD were younger but did not differ from the general population in terms of CDI risk factors or disease severity. The response to FMT and rate of CDI relapse in the IBD group were not statistically different compared to the rest of the cohort. The overall response rate in the IBD population was 75% at 12 weeks. Of the patients who failed FMT 4 of 5 patients had active or untreated IBD. CONCLUSION: Fecal microbiota transplantation provides a good alternative treatment option with high success rates for recurrent or refractory Clostridium difficile infection in patients with well-controlled IBD who fail standard antimicrobial therapy.

A Perplexing Case of Abdominal Pain That Led to the Diagnosis of Zollinger-Ellison Syndrome.

Zollinger-Ellison syndrome (ZES) is a rare clinical disorder, characterized by hypersecretion of gastric acid and multiple ulcers distal to the duodenal bulb. This occurs via the release of gastrin by neuroendocrine tumors known as gastrinomas. Patients with ZES present with nonspecific GI symptoms, which often leads to a delay in diagnosis. Our patient is a 55-year-old female with chronic abdominal pain, nausea, and diarrhea. She underwent EGD, EUS, MRCP, CT scans, and cholecystectomy, which did not reveal the cause of her symptoms. Repeat EGD showed a cratered ulcer in the second portion of the duodenum, suspicious for ZES. Serum gastrin was initially only moderately elevated while on PPI therapy, but chromogranin A was also elevated. Repeat gastrin level after stopping PPI therapy was 1639 pg/mL. Somatostatin receptor scintigraphy was obtained, which showed two small lesions in the gastrinoma triangle. She subsequently underwent a Whipple pancreaticoduodenectomy and pathology was positive for four microscopic foci of a neuroendocrine tumor. She reported improvement in her symptoms after surgery. This case highlights the need for increased awareness of ZES in patients with unexplained GI complaints and emphasizes the use of multiple modalities in the diagnosis of ZES.

Splenic Artery Embolization for Treatment of Refractory Ascites After Liver Transplantation.

Post-transplantation refractory ascites is uncommon; however, it can be a serious problem, increasing both morbidity and mortality in patients. Despite scant literature available, splenic artery embolization (SAE) has been shown to be an effective treatment for refractory ascites after cadaveric orthotopic liver transplantation (OLT). We report a successful use of therapeutic SAE for refractory ascites post-OLT.

Predictors of fecal transplant failure.

BACKGROUND: Clostridium difficile infection (CDI) is a significant healthcare burden, with increased morbidity and mortality. Traditional treatment regimens using antibiotics for recurrent CDI are significantly less successful compared with 80-90% with fecal microbiota transplantation (FMT). There is a paucity of data on failure rates and mortality after FMT in CDI. This study aims to identify the rates of failure, relapse, and mortality associated with FMT as well as the risk factors for FMT failure. METHODS: A large retrospective cohort study was carried out including all patients who underwent FMT from December 2012 through May 2014. Patient factors (demographics, comorbidities, immune-suppression, transplant history, antibiotics used, hospitalization, and surgeries), disease factors (number of episodes of CDI, treatments, and severity), and transplant factors (route and number of FMT) were examined. Failure of treatment was defined as no resolution of diarrhea in patients who had been treated with one or more fecal microbiota transplantation within 90 days of FMT. RESULTS: A total of 201 patients (age 66.6±18.3 years, 62.2% women) were included. The overall failure rate was 12.4%. Patients with failed fecal transplant had increased number of FMTs compared with those who responded (mean 1.92±0.997 vs. 1.29±0.615; P=0.004). No colectomies or death related to CDI were found in our patient population. Significant predictors of failure were female sex (P=0.016), previous hospitalization (P=0.006), and surgery before FMT (P=0.005). The overall mortality rate was 9.0% and failure of FMT was associated with an increased risk of death (odds ratio=5.833, confidence interval 2.01-16.925; P<0.05). CONCLUSION: FMT is a suitable alterative to antibiotic use for recurrent CDIs, with a high success rate. The results indicate that hospital-acquired CDI may be a predictor of failure of FMT.
