Sleep Disturbances Can Be Prospectively Observed in Patients with an Inactive Inflammatory Bowel Disease.

BACKGROUND: Poor sleep quality is associated with adverse health consequences. Sleep disturbances can impact the immune function and inflammatory processes. Little is known about sleep disturbances in patients with inflammatory bowel disease (IBD), while not in flare, i.e., inactive. AIMS: To prospectively explore the sleep quality of patients with an inactive IBD. METHODS: This pilot study included 36 consecutive patients with IBD and 27 healthy volunteers. All IBD patients had an inactive disease. Participants underwent an overnight ambulatory polysomnography. Data on disease duration, medications, complications, and treatment were collected from the medical records. RESULTS: The mean age of the IBD and the control groups was 39 ± 15 and 34.6 ± 9.6 years. A significantly less rapid eye movement (REM) sleep was noted in the IBD group vs. control (23.7 vs. 27.8%, p = 0.047); light sleep percentage and REM latency were also longer in the IBD group. Moreover, oxygen desaturation below 90% was more common in the IBD group. All other sleep parameters including respiratory disturbance index, apnea-hypopnea index, number of wakes, sleep latency, and snoring strength were similar in both groups. CONCLUSIONS: Inactive IBD is associated with sleep disturbances. A larger prospective study should be conducted to confirm these findings.

Five years of fecal microbiota transplantation - an update of the Israeli experience.

AIM: To evaluate and describe the efficacy of fecal microbiota transplantation (FMT) for Clostridium difficile infection (CDI) in a national Israeli cohort. METHODS: All patients who received FMT for recurrent (recurrence within 8 wk of the previous treatment) or refractory CDI from 2013 through 2017 in all the five medical centers in Israel currently performing FMT were included. Stool donors were screened according to the Israeli Ministry of Health guidelines. Clinical and laboratory data of patients were collected from patients' medical files, and they included indications for FMT, risk factors for CDI and disease severity. Primary outcome was FMT success (at least 2 mo free of CDI-related diarrhea post-FMT). Secondary outcomes included initial response to FMT (cessation of diarrhea within 7 d) and recurrence at 6 mo. RESULTS: There were 111 FMTs for CDI, with a median age of 70 years [interquartile range (IQR): 53-82], and 42% (47) males. Fifty patients (45%) were treated via the lower gastrointestinal (LGI, represented only by colonoscopy) route, 37 (33%) via capsules, and 24 (22%) via the upper gastrointestinal (UGI) route. The overall success rate was 87.4% (97 patients), with no significant difference between routes of administration (P = 0.338). In the univariant analysis, FMT success correlated with milder disease (P = 0.01), ambulatory setting (P < 0.05) and lower Charlson comorbidity score (P < 0.05). In the multivariant analysis, only severe CDI [odd ratio (OR) = 0.14, P < 0.05] and inpatient FMT (OR = 0.19, P < 0.05) were each independently inversely related to FMT success. There were 35 (32%) patients younger than 60 years of age, and 14 (40%) of them had a background of inflammatory bowel disease. CONCLUSION: FMT is a safe and effective treatment for CDI, with capsules emerging as a successful and well-tolerated route. Severe CDI is less likely to respond to FMT.

Fecal Transplantation for Treatment of Clostridium Difficile Infection in Elderly and Debilitated Patients.

BACKGROUND: Fecal microbiota transplantation (FMT) is a new technique recently introduced to treat recurrent Clostridium difficile infection (CDI). Little is known about the efficacy and risks of FMT in elderly and ill patients. AIM: To investigate FMT efficacy in ill and elderly patients compared to conventional treatment. METHODS: The study comprised two groups of patients between 2012 and 2016 with recurrent CDI at two medical centers in Israel. The study group received FMT and the controls conventional therapy. The primary end points were CDI recurrence, length of hospitalization, and short-term survival. RESULTS: Thirty-four patients altogether, (21 females, mean age 82 years) participated, 11 received FMT and 23 controls. Demographics and clinical characteristics were similar between the two groups. Comorbidity indexes, i.e., Charlson index was high in both groups. In the FMT group, 10/11 (90%) patients showed clinical improvement 3 days after initiating treatment compared to 9/23 (39%) in the control group, p = 0.02. Survival at 2 months did not differ between the groups (FMT 54%, Control 50%, p = 0.816), but mean survival in the FMT group was higher than in the control (12 vs. 4 months, respectively, p = 0.015). Two significant adverse events from the FMT group included suspected aspirations, both occurring during gastroscopy route of administration. CONCLUSIONS: FMT is effective for elderly and very ill patients. Safety is a concern, but is rare even in patients with much comorbidity. Colonoscopy may be the preferred route of FMT infusion.

A prospective study of fecal calprotectin and lactoferrin as predictors of small bowel Crohn's disease in patients undergoing capsule endoscopy.

BACKGROUND: Capsule endoscopy (CE) is often used to investigate small bowel Crohn's disease (CD). AIM: The aim of this study is to prospectively assess the value of fecal calprotectin and lactoferrin to predict CE findings. PATIENTS AND METHODS: Sixty-eight consecutive patients that were referred for CE were included. Stool samples for calprotectin and lactoferrin and blood samples were collected for relevant parameters. Correlation between fecal markers and CE findings was assessed and receiver operating characteristic (ROC) curves were built to determine the predictive values of fecal markers for the diagnosis of CD. RESULTS: Fecal calprotectin data was available for all the patients and lactoferrin data for 38. CE findings compatible with CD were found in 23 (33%) patients and 45 (67%) were negative for CD. The average age of the CD group was 34 compared to 46 in the non-CD group (p = .048). Median calprotectin and lactoferrin in the CD group and in the control group were 169 mg/kg vs. 40 (p = .004) and 6.6 mg/kg vs. 1 (p = .051), respectively. The area under the ROC curve was 0.767 for calprotectin and 0.70 for lactoferrin. A fecal calprotectin concentration of 95 mg/kg and fecal lactoferrin of 1.05 mg/kg had a sensitivity, specificity, positive predictive value and negative predictive value of 77 and 73%, 60 and 65%, 50 and 50%, and 84 and 84% in predicting CE findings compatible with CD. CONCLUSIONS: Fecal markers are simple and noninvasive surrogates for predicting CE findings compatible with CD. Fecal markers can help determine which patients should be referred for CE. ClinicalTrials.gov Identifier: NCT01266629.

A Retrospective Comparison of Fecal Microbial Transplantation Methods for Recurrent Clostridium Difficile Infection.

BACKGROUND: Antibiotic treatment of Clostridium difficile infection (CDI) has a high failure rate. Fecal microbiota transplantation (FMT) has proven very effective in treating these recurrences. OBJECTIVES: To determine which method of fecal microbiota transplantation (upper or lower gastrointestinal) and which type of donor (a relative or unrelated) is superior. METHODS: This is a retrospective analysis of treatment protocols and outcomes in 22 patients with refractory or recurrent CDI who underwent FMT at two Israeli facilities. Each center used a different donor type, stool preparation and method of delivery. The Tel Aviv Sourasky Medical Center used unrelated fecal donors and frozen stool samples and delivered them primarily (92%) via the lower gastrointestinal (GI) tract. Shaare Zedek Medical Center used fresh donor stool of relatives and delivered them primarily (90%) via the upper GI tract. RESULTS: FMT had an overall 2 month cure rate of 89%. Patients treated with FMT that was executed through the lower GI tract recovered faster from the infection (1.6 ± 1.08 vs. 2.4 ± 1 days for the upper tract, P = 0.03). The results also showed that patients who received lower GI tract FMTs were more likely to be cured of CDI (100% vs. 75% for upper tract FMTs, P = 0.16). Five patients (22%) died of CDI/FMT-unrelated causes and two (10%) died of CDI/FMT-related causes during the study period. CONCLUSIONS: Lower GI tract FMT is a safe and effective treatment for refractory and recurrent CDI, and yields quicker results than upper GI tract FMT.

Inflammatory bowel disease: an emergent disease among Ethiopian Jews migrating to Israel.

BACKGROUND: The development and characteristics of inflammatory bowel disease (IBD) in Ethiopian Jewish immigrants to Israel were investigated. METHODS: A case-control study was conducted in 7 tertiary care hospitals in Israel. Patients of Ethiopian origin with IBD >6 months were included. Time of disease onset after immigration and age at diagnosis were recorded. Randomly chosen patients with IBD of Ashkenazi Jewish origin served as controls. Demographics and clinical parameters were compared between the 2 cohorts. RESULTS: Thirty-two Ethiopian patients with IBD were compared with 33 Ashkenazi Jewish patients with IBD. Crohn's disease (CD) was more prevalent than ulcerative colitis (UC) in the Ethiopian group compared with the Ashkenazi group (94% versus 73%, P = 0.02). No Ethiopian-origin patient had a positive family history of IBD compared with 42% of Ashkenazi-origin patients (P < 0.001). Arthritis was more common in Ashkenazi than in Ethiopian patients (27% versus 3%, P < 0.01). One Ashkenazi patient with CD had upper gastrointestinal involvement compared with 7 (23%) in the Ethiopian group (P < 0.02). All other clinical measures were similar between the 2 cohorts. The Ethiopian group lived in Israel with a mean of 13 ± 5 years, and 75% were born in Ethiopia. The shortest time between immigration and developing IBD was 8 years (range, 8-26; median 16 yrs). No Ethiopian patient was diagnosed before immigration. CONCLUSIONS: Ethiopian Jews migrating to Israel are at risk of developing IBD. Larger cohorts are needed to determine the relative importance of environmental and genetic factors that cause IBD in these patients.

Hepatotoxicity due to tocilizumab and anakinra in rheumatoid arthritis: two case reports.

Elevation of liver enzymes in patients with rheumatoid arthritis treated with the biological agents, tocilizumab and anakinra, is now well documented. However, histological characterization of these effects and outcomes has not been defined. Here we report toxic liver effects in two women with rheumatoid arthritis, refractory to all nonbiological therapies, following treatment with anakinra and tocilizumab. Liver biopsy in both cases showed focal necrosis of hepatocytes as a hallmark of drug toxicity, along with steatosis and early fibrosis. In addition, the patient treated with anakinra demonstrated inflammatory changes. Tocilizumab was continued with no further deterioration in liver function. Withdrawal of anakinra led to rapid normalization of liver function. The biological agents, tocilizumab and anakinra, may result in significant histological hepatic changes, including necrosis, but despite this, the outcome appears to be good.

Fecal calprotectin as a predictor of abnormal colonic histology.

PURPOSE: Gastroenterologists have been seeking reliable noninvasive indices of inflammatory and malignant bowel disease. This prospective study was to assess the value of fecal calprotectin in predicting abnormal histologic findings in patients undergoing colonoscopy. METHODS: Stool specimens supplied before colonoscopy by 72 consecutive patients were measured for calprotectin levels, and the findings correlated with the colonoscopy results and other fecal and blood parameters. Receiver operating characteristics curve analysis was used to determine the predictive value of fecal calprotectin for abnormal colonic histology. RESULTS: Patients with abnormal histologic findings had significantly higher calprotectin levels (218 +/- 125 mg percent) than patients with normal colonoscopy (77 +/- 100 mg percent). There was a highly significant correlation between calprotectin levels and erythrocyte sedimentation rate (r = 0.45, P = 0.008), positive fecal occult blood test (r = 0.57, P = 0.0001), and abnormal colonic histology (r = 0.54, P = 0.0001). Patients with active inflammatory bowel disease had higher calprotectin levels than the rest of the study patients (r = 0.3; P = 0.01). On multivariate analysis, calprotectin was a significant predictor of abnormal colonic histology (P = 0.005; odds ratio, 1.007; 95 percent confidence interval, 1.002-1.012). The area under the receiver operating characteristics curve was 0.79. A fecal calprotectin concentration of 150 microg/ml had a sensitivity of 75 percent, specificity of 84 percent, positive predictive value of 80 percent, and negative predictive value of 75 percent in predicting abnormal colonic histology. CONCLUSIONS: Fecal calprotectin may serve as a simple, noninvasive surrogate marker of abnormal histologic findings in patients scheduled for colonoscopy.
