AbstractBackground/objectivesSeveral epidemiologic studies have suggested that patients with celiac disease may be at an increased risk of sarcoidosis but the results were inconsistent. This systematic review and meta‐analysis was conducted with the aim to better characterize this risk by summarizing all available data.MethodsA literature review was performed using MEDLINE and EMBASE database from inception to February 2019. Studies that compared the risk of sarcoidosis among patients with celiac disease versus individuals without celiac disease were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random‐effect, generic inverse variance method.ResultsOf 426 retrieved studies, four studies with 693 639 participants met the eligibility criteria and were included in meta‐analysis. The risk of sarcoidosis among patients with celiac disease was higher than individuals without celiac disease with the pooled OR of 7.16 (95% CI, 1.48‐34.56). The statistical heterogeneity of this study was high (I2 = 95%).ConclusionsThis systematic review and meta‐analysis found a significantly higher risk of sarcoidosis among patients with celiac disease.

Background Limited data exist regarding the effects of end-stage renal disease (ESRD) on acute pancreatitis (AP). This study aimed to evaluate the association between ESRD and outcomes and resource utilization of AP. Materials and methods The 2014 National Inpatient Sample database was used to identify all hospitalized patients with a principal diagnosis of AP. Propensity score matching was performed to create a matched cohort of ESRD and non-ESRD patients. The in-hospital mortality, morbidity, resource utilization and expenditures of AP in ESRD patients were compared to non-ESRD patients. Multivariate analysis was performed for further adjustment for potential confounders. Results Of 382 595 AP patients, 7380 ESRD patients and 8050 non-ESRD patients were created after propensity score matching. ESRD patients had more tendency to have hypercalcemia-related or AP-related to other/unspecified causes, whereas non-ESRD patients had more tendency to have alcohol-related, gallstone-related, and hypertriglyceridemia-related AP. In multivariate analysis, ESRD was associated with increased in-hospital mortality, increased length of hospital stay, and increased hospitalization costs and charges. No differences were observed in inpatient morbidity, imaging study use, and procedures performed during hospitalization. Conclusion In this large nationwide study using inpatient USA database, we demonstrate higher AP-related mortality, and resource utilization among ESRD patients when compared with non-ESRD patients.

Background and aim Nonalcoholic fatty liver disease (NAFLD) may be associated with sarcopenia. This study aims to determine whether sarcopenia is independently associated with NAFLD and advanced fibrosis. Participants and methods Cross-sectional data from 11 325 participants in the third National Health and Nutrition Examination Survey were analyzed. NAFLD was defined as the presence of hepatic steatosis from the ultrasound. Sarcopenia was defined as the skeletal muscle index. Results NAFLD was more common in participants with sarcopenia than in those without (46.7 vs. 27.5%). Univariate analysis showed that sarcopenia was associated with NAFLD [odds ratio (OR): 2.31; 95% confidence interval (CI): 2.01–2.64], which remained significant after adjustment for age, sex, ethnicity, metabolic risk factors (OR: 1.24; 95% CI: 1.03–1.48). This finding persisted after adjustment for C-reactive protein as a marker of chronic inflammation. NAFLD-associated advanced fibrosis was more common in participants with sarcopenia than in those without (7.8 vs. 1.6%). Sarcopenia was associated with NAFLD-associated advanced fibrosis independent of metabolic risk factors (OR: 1.79; 95% CI: 1.18–2.72). Conclusion Sarcopenia was independently associated with increased odds of NAFLD and NAFLD-associated advanced fibrosis independent of well-defined risk factors. Interventions to strengthen muscle mass may reduce the burden of NAFLD and advanced fibrosis.

AbstractBackgroundBone and mineral metabolism disorders are common among end‐stage renal disease (ESRD) patients, which could lead to hip fracture. It is unclear whether the hip fracture risk is different among patients on hemodialysis (HD) versus peritoneal dialysis (PD). This meta‐analysis was conducted to evaluate the hip fracture risk in ESRD patients on HD, when compared to PD.MethodsA literature review was conducted in EMBASE, MEDLINE, and Cochrane databases through January 31, 2018 to identify studies that appraised the rate or risk of hip fracture among patients on HD, when compared to PD. Effect estimates from the individual studies were derived and consolidated utilizing random‐effect, generic inverse variance approach of DerSimonian and Laird.ResultsFive cohort studies with 1 276 677 ESRD patients were enrolled. HD status was associated with a significantly higher risk of hip fracture with the pooled odds ratio (OR) of 1.61 (95% confidence interval [CI] 1.50‐1.73, I2 = 10.0%), compared with PD. When the analysis was limited to studies with confounder‐adjusted analysis, the pooled OR of hip fracture among HD patients was 1.57 (95% CI 1.43‐1.72, I2 = 13.6%). Funnel plots and Egger's regression test demonstrated no significant publication bias in our meta‐analysis.ConclusionsAmong ESRD patients, HD status is associated with a 61% higher risk of hip fracture compared to PD.

AbstractBackground & AimsNonalcoholic fatty liver disease (NAFLD) has become the most common liver disease in Western countries. Smoking and diabetes mellitus (DM) have been shown to increase mortality; however, whether NAFLD adds to the detrimental effect of smoking in DM and non‐DM patients is unknown. We evaluated the possible interactive effect of NAFLD and smoking on mortality risk in a US population‐based sample.MethodsCross‐sectional data from 11 205 participants in the third National Health and Nutrition Examination Survey were analysed. NAFLD was defined as ultrasonographic hepatic steatosis without evidence of other liver diseases. Proportional hazards regression modelling was used to test for the multiplicative interaction of NAFLD and smoking on overall mortality, controlling for DM.Results36.5% of the participants had NAFLD of whom 21.1% were current smokers, while among non‐NAFLD subjects, 26.2% reported current smoking. Smoking was associated with a hazard ratio (HR) of 2.23 (95% confidence interval (CI): 1.87‐2.65) among non‐NAFLD subjects, and 2.31 (95% CI: 1.33‐2.92, P < 0.01) among NAFLD patients. In contrast, the HR for NAFLD was 1.01 (95% CI: 0.78‐1.31, P = 0.96) among smokers and 0.98 (95% CI: 0.87‐1.10, P = 0.73) among non‐smokers. There was no evidence of interaction between NAFLD and smoking (HR = 1.01, 95% CI: 0.74‐1.38, P = 0.94) in the combined model.ConclusionWe found that smoking increased mortality by two‐fold among the US population. Although the magnitude of the increase in mortality did not differ from that in non‐NAFLD subjects, smoking represents a modifiable determinant of long‐term outcomes in NAFLD patients.
