The impact of overweight on diverticular disease: a cross-sectional multicenter study.

INTRODUCTION: The prevalence of colonic diverticulosis and diverticulitis has significantly increased in recent years. Obesity is a well­known risk factor for diverticulitis, but far less is known about the association between diverticulitis and overweight. OBJECTIVE: We aimed to examine the association between overweight and diverticulitis and to study the potential relationship between body mass index (BMI) and disease severity. PATIENTS AND METHODS: We conducted a retrospective, multicenter study. Patients diagnosed with diverticulosis confirmed by colonoscopy were included. The diagnosis of diverticulitis was confirmed by computed tomography. Weight status was defined as normal in the case of BMI in the range of 18.5- 24.9 kg/m2, overweight when BMI was 25-29.9 kg/m2, and obesity with BMI equal or above 30 kg/m2. RESULTS: The study included 592 patients. Among them, 157 (26.5%) had normal BMI, 191 (32.3%) were overweight, and 244 (41.2%) were obese. Patients with BMI above the normal range, overweight and obese were at higher odds of acute diverticulitis as compared with those with normal BMI. This was evidenced by the values of odds ratio (OR) 3.10 (95% CI, 2.00-4.73; P <0.001) for weight above the normal range, OR 1.85 (95% CI, 1.14-3.00; P = 0.01) for overweight, and OR 4.50 (95% CI, 2.84-7.12; P <0.001) for obese patients. CONCLUSIONS: Overweight was associated with an increased risk of diverticulitis among patients with diverticulosis. Since overweight is a modifiable factor, this observation has preventive importance.

Predictors of in-hospital mortality among patients with clostridium difficile infection: a multicenter study.

BACKGROUND: Clostridium difficile infection (CDI)-associated mortality is a major global health concern. Several clinical and laboratory parameters have been linked to poor prognosis in patients with CDI. In the current study, we aimed to assess the rate of in-hospital mortality among Israeli CDI patients and to look for clinical and laboratory parameters associated to death. METHODS: We performed a multicenter retrospective study enrolling all patients above 18-years old who were hospitalized for CDI or with diagnosis made during hospitalization in two regional, teaching hospitals in the north of Israel (Galilee Medical Center, Nahariya and the Nazareth Hospital, Nazareth, Israel), from January 1, 2015 until January 1, 2020. All files of eligible patients were reviewed for demographic (age, gender), medical history and laboratory tests. RESULTS: Overall, we included in the study 180 patients, among them 56 died in hospital due to CDI (group A) while 124 survived (group B). The average age in groups A and B was 77.02±13 vs. 71.5±19.1, respectively. On univariate analysis, several clinical and laboratory parameters were associated with in-hospital mortality, including: advanced age, renal failure, antibiotics treatment while on treatment for CDI, need for mechanical ventilation, level of hemoglobin, white blood cells (WBC) and neutrophils count, neutrophil/lymphocyte ratio, serum level of albumin, creatinine and C reactive protein. On multivariate logistic regression analysis, only 4 parameters showed statistically significant association with in-hospital mortality, including age (odds ratio [OR]: 6.97, 95%confidence interval [CI]: 4.94-8.72, P=0.003), renal failure (OR: 3.72, 95% CI: 1.22-11.24, P=0.02), WBC count (OR: 1.09, 95% CI: 1.02-1.16, P=0.008), and lower albumin level (OR: 47.62, 95% CI: 10.31-200, P<0.0001). CONCLUSIONS: In this retrospective, multicenter study, age, serum albumin level, leucocytes count, and renal failure were the main predictors of in-hospital mortality in patients with CDI. Thus, antibiotic use should be weighed carefully in elderly comorbid patients, at increased risk of mortality from CDI .Prospective multicenter randomized studies investigating the effect of albumin infusion on in-hospital death of CDI patients are needed, thus enabling us to direct monitoring and treatment accordingly.

Proton Pump Inhibitor Use May Increase the Risk of Diverticulitis but Not It's Severity among Patients with Colonic Diverticulosis: A Multicenter Study.

Colonic diverticular disease, especially diverticulitis constitutes a major cause of hospitalization and an economic burden in developed countries. Proton pump inhibitors (PPIs) are among the commonest drugs used to treat several diseases affecting the upper gastrointestinal tract. A few studies have reported that the use of Proton Pump Inhibitors PPIs caused dysbiosis. In this study, we searched for a relationship between PPI use and the onset and severity of diverticulitis in patients with colonic diverticulosis. In a retrospective study, patients who were hospitalized for documented diverticulitis were enrolled as cases and compared with a control group of patients with uncomplicated diverticulosis. Overall, 613 patients who had a diagnosis of diverticulosis were included in the study, 217 of whom had diverticulitis. After multivariate analysis, the non-modifiable risk factors associated with diverticulitis included: age (p < 0.0001), hypertension (p < 0.0001), chronic renal failure (p = 0.007), diabetes mellitus (p < 0.0001), and left colon location (p = 0.02). However, among the modifiable factors, only PPI use (p < 0.0001) showed a significant association. Advanced disease severity (according to Hinchey classification of diverticulitis stages II-IV) was associated with aspirin use (p = 0.0004) and pan-colonic location (p = 0.02). PPI use was the only modifiable factor significantly associated with diverticulitis, but not with its severity, among patients with diverticulosis. This observation should be confirmed in future multicenter prospective studies.
