Different effects of chronic omeprazole use on osteoporotic fractures rate in the elderly.

AIMS: To investigate the potential association of chronic use of omeprazole with the occurrence of osteoporotic fractures (OF) in community-dwelling elderly subjects. METHODS: The cohort consisted of community-dwelling residents aged >65 years registered with a large health maintenance organization in Israel between January 2002 and December 2016. Data were retrospectively collected from the electronic medical files on demographics, parameters known to be associated with OF, diagnoses of osteoporotic hip, wrist, and vertebral fractures, and chronic use of omeprazole (>11 prescriptions/year). Time to OF/death/end of study was calculated from the beginning of the study (2002). The risk of fractures in the chronic users of omeprazole was analyzed by multivariate Cox proportional hazard regression model. RESULTS: In total, 46 805 subjects were included (41% men), mean age 83.4±6.4 years, of whom 10 272 (21.9%) were chronic users of omeprazole. During 14 years of follow-up, OF were diagnosed in 414 (4.0%) omeprazole users and 1007 (2.8%) omeprazole nonusers (p < 0.001). In a Cox regression model adjusted for age and gender only, chronic use of omeprazole was associated with a 16% excess of OF. However, when parameters known to be associated with OF were entered into the multivariate Cox regression model, chronic use of omeprazole was not found to be an independent risk factor for OF, either overall (adjusted hazard ratio = 0.965, 95% confidence interval 0.86-1.08, P = .55) or specifically, in the ≥85 years age group (adjusted hazard ration = 0.780, 95% confidence interval 0.635-0.958, P < .05) in which an inverse correlation between omeprazole use and OF, was demonstrated. CONCLUSIONS: Chronic use of omeprazole was not associated with the occurrence of OF in elders.

Serum Albumin to Creatinine Ratio as Predictor for 30-Day All-Cause Mortality in Patients with Clostridium Di!cile-Associated Diarrhea.

BACKGROUND: Clostridium difficile-associated diarrhea (CDAD) is a significant cause of mortality and morbidity in hospitalized patients. Several scores have developed in order to assess the severity of CDAD. OBJECTIVE: To determine the role of the serum albumin to creatinine ratio (sACR) in predicting the 30-day all-cause mortality of patients with CDAD in comparison with other known severity scores of CDAD. METHODS: A retrospective study was conducted at Baruch-Padeh Medical Center from January 2014 to December 2019. Patients with CDAD were recruited from Internal Medicine Departments, Intensive Care Units, and Surgical Departments. Data on demographic characteristics, clinical signs, underlying conditions, and several risk factors for CD infection were collected. We compared between severity scores of CDAD, such as ATLAS, the CDAD severity score, and the sACR in predicting the 30-day all-cause mortality in hospitalized patients with CDAD. RESULTS: 116 patients with CDAD were included. The ATLAS, CDAD scores, and sACR were calculated for all patients. The mean age of the participants was 71.4±16.4 years. 57.7% were of female gender. Fifty-two (44.8%) died within 30 days. An ATLAS score of ≥8 points had a 3.6-fold higher risk of 30-day all-cause mortality in hospitalized patients with CDAD (HR 3.6, 95% CI 3.28-3.99, p=0.001), a CDAD score of ≥5 points (HR 1.1, 95% CI 0.91-1.42, p=0.05), and a sACR≤3.4 (HR 1.5, 95%CI 1.25-1.82, p=0.04). CONCLUSION: In this study, it was found that a sACR≤3.4 could predict the 30-day all-cause mortality in patients with CDAD.

The Prognostic Value of Inflammatory Markers in Clostridium difficile-associated Diarrhea.

BACKGROUND: The incidence of Clostridium difficile-associated diarrhea (CDAD) is increasing and is associated with significant morbidity and mortality. Therefore, there is a need to find new tools to determine the severity of the disease. OBJECTIVES: To investigate the prognostic values of inflammatory markers such as mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR), and C-reactive protein (CRP) in patients with CDAD. METHODS: The study comprised of 100 patients diagnosed with CDAD. The study included an additional control group of 69 patients with diarrhea who were negative for C. difficile toxin. The control group was age- and sex-matched and hospitalized at the same time period. NLR and MPV were obtained from complete blood count results. Serum CRP levels were measured by the latex particle enhanced immunoturbidimetric assay. Blood samples for all inflammatory markers were collected at time of diagnosis and prior to initiating the antibiotic therapy. Demographic, clinical, laboratory, and prognostic data were collected from medical records for a period of 90 days from the initial diagnosis of CDAD. RESULTS: The mean age of the CDAD group was 68.6 ± 21.5 years compared to 65.6 ± 24.5 in the control group (P = 0.29). Our findings show that patients with CDAD had significantly higher NLR, MPV and serum CRP levels compared to the control group (P < 0.001)). Moreover, significantly higher levels were observed when CDAD was fatal (P < 0.001). CONCLUSIONS: Elevated NLR, MPV, and serum CRP levels may serve as biomarkers for prediction of recurrence and mortality in patients with CDAD.

Non-alcoholic Fatty Liver Disease is Associated with Recurrent Urinary Tract Infection in Premenopausal Women Independent of Metabolic Syndrome.

BACKGROUND: Recently, studies have found that non-alcholic fatty liver disease (NAFLD) is associated with bacterial infections. Attempts to identify risk factors for recurrent urinary tract infections (rUTIs) are still underway. OBJECTIVES: To examine a possible association between NAFLD and rUTIs among premenopausal women. METHODS: In a case-control study, 1009 hospitalized premenopausal women with a UTI during a period of 3 years were retrospectively studied. A total of 186 subjects with rUTIs and 186 controls without a history of rUTIs were included in this study. Each participant had an abdominal ultrasonogram as part of the inclusion criteria. The two groups were compared in terms of risk factors for rUTIs, such as maternal history of rUTIs, use of contraceptives, frequency of sexual intercourse, metabolic syndrome, obesity, use of probiotics, serum levels of vitamin D, and NAFLD. An rUTI was defined as three or more episodes of UTI over a period of 1 year. NAFLD was diagnosed based on abdominal ultrasonography examination. RESULTS: Mean age of the 372 participants was 39.7 ± 5 years. NAFLD was diagnosed in 81/186 subjects (43.5%) with rUTIs vs. 40/186 controls (21.5%), P = 0.05. Women with rUTIs were more often obese and presented with lower serum levels of vitamin D than controls. Multivariate analysis showed that NAFLD (odds ratio = 1.6, 95% confidence interval 1.3-2.0, P = 0.04) were associated with rUTIs in premenopausal women. CONCLUSIONS: NAFLD was associated with rUTI in premenopausal women, independent of metabolic syndrome. Further studies are needed to confirm this association.
