Metformin with Versus without Concomitant Probiotic Therapy in Newly Diagnosed Patients with Type 2 Diabetes or Prediabetes: A Comparative Analysis in Relation to Glycemic Control, Gastrointestinal Side Effects, and Treatment Compliance.

BACKGROUND: To evaluate the impact of concomitant use of probiotic BB-12 in metformin-treated patients with type 2 diabetes or prediabetes on glycemic control, metformin-related gastrointestinal side effects, and treatment compliance. METHODS: A total of 156 patients (mean [standard deviation] age: 50.9 [9.9 years], 74.4% females) with newly diagnosed type 2 diabetes or prediabetes were randomly assigned to receive either metformin alone (n = 84, MET group) or metformin plus Bifidobacterium animalis subsp. lactis (BB-12) probiotic (n = 72, MET-PRO group). Data on body mass index (kg/m2), fasting blood glucose (mg/dL), blood lipids, and glycated hemoglobin (HbA1c) levels were recorded at baseline and at the third month of therapy. Data on gastrointestinal intolerance symptoms and treatment noncompliance were also recorded during post-treatment week 1 to week 4. RESULTS: MET-PRO versus MET therapy was associated with a significantly higher rate of treatment compliance (91.7% vs 71.4%, P = .001), greater reduction from baseline HbA1c values (0.9 [0.4-1.6] vs 0.4 [0-1.6] %, P < .001) and lower likelihood of gastrointestinal intolerance symptoms, including abdominal pain (P = .031 to <.001), diarrhea (P = .005 to <.001) and bloating (P = .010 to <.001). Noncompliance developed later (at least 15 days after the therapy) in a significantly higher percentage of patients in the MET group (P = .001 for 15-21 days and P = .002 for 22-28 days). CONCLUSION: In conclusion, the present study proposes the benefit of combining probiotics with metformin in the treatment of patients with T2D or prediabetes in terms of improved glycemic control and treatment adherence rather than correction of dyslipidemia or weight reduction.

Gallbladder Stone Prevalence and Related Factors in Predialysis Chronic Kidney Disease Patients.

BACKGROUND: The aim of this study was to determine the prevalence and factors associated with gallbladder stone in patients with predialysis chronic kidney disease. METHODS: This cross-sectional study retrospectively examined follow-up data of patients with chronic kidney disease between January 2015 and December 2020 at the Health Sciences University Antalya Training and Research Hospital who had undergone abdominal ultrasonography for any reason. Patients with gallbladder stone on abdominal ultrasonography and history of cholecystectomy due to gallbladder stone were identified as the gallstone group. The prevalence of gallbladder stone was determined according to disease stage. Patients with and without gallbladder stone were compared in terms of demographic and clinical characteristics and laboratory parameters that may be associated with the development of gallbladder stone. RESULTS: A total of 511 patients had chronic kidney disease (stages 3, 4, and 5 in 303 [59.3%], 176 [34.4%], and 32 [6.3%], respectively). The gallstone prevalence rates were 25.1%, 30.1%, and 46.9% in stage 3, 4, and 5 chronic kidney disease, respectively, and that in all the patients was 28.2% (95% CI: 24.3-32.3, P = .026). Logistic regression analysis revealed that increased age (odds ratio: 1.045; 95% CI: 1.027-1.063, P < .001) and decreased estimated glomerular filtration rate (odds ratio: 0.974; 95% CI: 0.956-0.991, P = .004) were associated with gallbladder stone. CONCLUSION: The prevalence of gallbladder stone was high in the predialysis patients with chronic kidney disease and increased with increasing disease stage. High age and low estimated glomerular filtration rate were associated with gallbladder stone formation.

Using two-holed needles for both arterial and venous accesses to the arteriovenous fistula to improve flow during hemodialysis.

This prospective study compared methods using both arterial and venous needles with back eyes with those using only arterial needle with back eye for arteriovenous fistula cannulation. Sixty-one patients receiving hemodialysis (HD) via an arteriovenous fistula were evaluated. All patients underwent arteriovenous fistula puncture using only arterial needle with back eye in first 3 months and both arterial and venous needles with back eyes in following 3 months. Arterial and venous pressures, blood flow velocities, total blood volume cleared, and Kt/V values were compared. Mean blood flow velocity, arterial pressure, Kt/V, and cleared total blood volume values were higher and venous pressure was lower in patients who underwent cannulation using both needles with back eyes than in those with only the arterial needle with back eye. For arteriovenous fistula cannulation, using both arterial and venous needles with back eyes provides adequate HD more successfully.

Visceral fat index: a novel predictor for coronary collateral circulation.

Objective This study was designed to investigate the role of visceral adiposity along with other clinical parameters in predicting poor coronary collateral circulation (CCC) among patients with severe obstructive coronary artery disease (CAD). Subjects and methods A total of 135 patients with severe obstructive CAD and good (n = 70) or poor (n = 65) CCC were included. Data on angiographically detected CCC, the quality criteria for CCC (Rentrop scores) and visceral fat index (VFI) obtained via bioelectrical impedance were compared between good and poor CCC groups. Independent predictors of poor CCC, the correlation between VFI and Rentrop score and the role of VFI in the identification of CCC were analyzed. Results A significant negative correlation was noted between VFI and Rentrop scores (r = -0.668, < 0.001). The presence of hypertension (OR 4.244, 95% CI 1.184 to 15.211, p = 0.026) and higher VFI (OR 1.955, 95% CI 1.342 to 2.848, p < 0.001) were shown to be independent predictors of an increased risk for poor CCC. ROC analysis revealed a VFI > 9 (AUC [area under the curve] (95% CI): 0.898 (0.834-0.943), p < 0.0001) to be a potential predictor of poor CCC with a sensitivity of 95.38% and specificity of 85.71%. Conclusion In conclusion, our findings revealed comorbid hypertension and higher VFI to significantly predict the risk of poor CCC in patients with severe obstructive CAD.

The role of Blastocystis hominis in the activation of ulcerative colitis.

BACKGROUND/AIMS: Several studies have shown that a change in microbiota plays an important role in the pathogenesis of inflammatory bowel disease (IBD). Furthermore, with the emergence in recent studies of differences according to the subtype of IBD and whether the disease is active or in remission, there has started to be research into the relationship between IBD and several microorganisms. Blastocystis hominis is primary among these organisms. The aim of the present study was to determine the role of B. hominis in the acute flare-up of ulcerative colitis (UC). MATERIALS AND METHODS: A total of 114 patients with UC were included in the study, with 52 in the active phase. The Mayo scoring system was used for the activity index. Patients determined with a flare-up agent other than B. hominis were excluded from the study. Fecal samples of the patients were examined by the polymerase chain reaction method for the presence of B. hominis. RESULTS: B. hominis positivity was determined in 37 (34%) patients with UC. Of the patients, 17 (32.6%) were in the acute flare-up phase, and 20 (32.2%) were in remission (p=0.961). In 11 (64.7%) of the B. hominis positive patients, the disease severity was determined as mild-moderate (p<0.001). CONCLUSION: The results of the present study showed that while there was no difference between the active and remission phases in respect of B. hominis presence, there was milder involvement in those determined with B. hominis.

Neutrophil-to-Lymphocyte Ratio as a Potential Early Marker of Antibiotic Resistance in Patients with Infected Cirrhotic Ascites.

BACKGROUND: To evaluate the role of neutrophil-to-lymphocyte ratio (NLR) in identification and management of infected ascites among patients with cirrhosis. METHODS: A total of 439 patients (mean (SD) age: 64.5 (± 12.7) years, 63.3% were males) hospitalized with cirrhotic ascites were included in this retrospective study. Data on patient demographics, etiology of cirrhosis, type of ascites (sterile ascites, infected ascites), culture findings treatment response (antibiotic resistance vs. sensitivity) and baseline (Day 0), Day 1 and Day 2 levels for serum C-reactive protein (CRP; mg/L), and NLR were recorded. Receiver operating characteristics (ROC) curve was plotted to determine performance of % change from baseline NLR on Day 1 in identifying treatment response. RESULTS: In patients with infected ascites, antibiotic resistant patients had significantly higher Day 1 (6.9 (1.9 - 74.9) vs. 4.9 (1.1 - 51.1), p = 0.001) and Day 2 (8.0 (2.6 - 75.9) vs. 4.0 (1.1 - 40.3), p = 0.000) levels for NLR as compared with antibiotic sensitive patients, while the two groups had similar baseline (Day 0) NLR values (5.8 (1.1 - 62.3) vs. 5.7 (1.1 - 72.3), p = 0.969). ROC analysis revealed less than 0.93% decrease from baseline NLR on Day 1 (AUC (95% CI): 0.852 (0.799 - 0.895), p < 0.001) to be a potential marker of antibiotic resistance with a sensitivity of 87.72% and specificity of 88.50%. CONCLUSIONS: Our findings indicate percent change from baseline NLR on Day 1 to be a potential early marker of antibiotic resistance in patients with infected cirrhotic ascites. Our findings emphasize the role of determining NLR levels in earlier recognition of treatment failure and thus prompt modification of antibiotic treatment in cirrhotic patients with infected ascites.

Short-Term Effect of High-Dose Pantoprazol on Serum and Urinary Magnesium Levels.

BACKGROUND: Proton pump inhibitor (PPI) induced hypomagnesemia is a completely unexplained issue and cases are still being reported. Long-term use is the main factor, but there are a few articles stating that it may also emerge with short-term use. We aimed to evaluate the changes of serum and urine magnesium levels during shortterm high dose pantoprazol treatment. METHODS: The serum and 24-hour urine magnesium levels of 58 patients were evaluated during the course of 2 days. Of 58 patients, 25 were allowed oral intake on the 3rd day of hospitalization and thus, 24-hour urine for 3 days was collected from 33 patients. RESULTS: There were no significant differences in the mean levels of serum magnesium and the median levels of urine magnesium. When the magnesium levels were evaluated by age over and under 60 years, the baseline serum magnesium level was significantly higher than the 1st level in patients aged ≥ 60 years (p = 0.029). The 3rd day serum magnesium level was significantly higher than the baseline and 1st day levels in those aged < 60 years (p = 0.049). CONCLUSIONS: We showed that plasma levels and urinary excretion of magnesium did not change significantly during high-dose pantoprazol treatment. It can be hypothesized that magnesium levels are not affected by PPIs in short-term usage. Age and other contributing factors may have more impact on PPI induced hypomagnesemia. Patients aged over 60 years might be handled carefully under proton pump inhibitors treatment.

Differentiating Transudative From Exudative Ascites Using Quantitative B-Mode Gray-Scale Ultrasound Histogram.

OBJECTIVE: The purpose of this article is to differentiate exudative from transudative ascites using B-mode gray-scale ultrasound histogram analysis. SUBJECTS AND METHODS: Sixty-two consecutive patients with ascites were prospectively studied from June 2014 through June 2015. All underwent ultrasound (US) and paracentesis in the radiology department. Five patients were excluded (three with hemorrhage and two with peritoneal carcinomatosis). The remaining 57 patients were divided into those with exudative and transudative ascites according to results of paracentesis. Electronically recorded US images were transferred to a workstation, and gray-scale histograms were generated. The ascites-to-rectus abdominis muscle echogenicity ratio (ARAER) was obtained from ascites adjacent to the rectus abdominis muscle. ROC curves were used to evaluate the sensitivity and specificity of this method in differentiating exudative from transudative ascites. RESULTS: ARAERs for exudative ascites were significantly higher than those for transudative ascites (p < 0.001). ROC was done to evaluate ARAERs for exudative ascites. The best cutoff value for ARAER histogram was 0.002. The sensitivity and specificity of ARAER were 87.5% and 79.2% (AUC = 0.843), respectively. CONCLUSION: ARAER is an easily applicable noninvasive quantitative sonographic method with high sensitivity and specificity in differentiating exudative from transudative ascites.

Use of probiotics as an adjuvant to sequential H. pylori eradication therapy: impact on eradication rates, treatment resistance, treatment-related side effects, and patient compliance.

BACKGROUND/AIMS: To evaluate the effect of probiotics administered as an adjuvant to sequential Helicobacter pylori (H. pylori) eradication therapy on treatment outcome and patient compliance. MATERIALS AND METHODS: In total, 159 patients with H. pylori infection receiving sequential H. pylori eradication therapy were included in this randomized placebo-controlled study. Starting from day 0 of sequential eradication therapy (ERA), patients in the ERA+probiotic group [n=53, mean (SD) age: 47.7 (14.0) years, 54.7% were females] also received a probiotic supplement with Bifidobacterium animalis subsp. lactis B94 (1 capsule/day), patients in the ERA+placebo group [n=52, mean (SD) age: 46.4 (13.4) years, 51.9% were males] received placebo treatment (1 capsule/day), and patients in the ERA-only group [n=54, mean (SD) age: 46.3 (11.9) years, 55.6% were females] received no additional treatments. Eradication rates, patient compliance, and side effects of eradication therapy were recorded in each treatment group. RESULTS: Significantly higher eradication rates were noted in the ERA+probiotic group (86.8% vs. 70.8%, p=0.025) than in the combined ERA (ERA-only and ERA-placebo) group. Non-compliance with anti-H. pylori treatment was noted in 24 (15.1%) of 159 patients. Lower rates of first week treatment non-compliance due to diarrhea (1.88% vs. 12.26%, p=0.036) were noted in the ERA+probiotic group than in the combined ERA (ERA-only and ERA-placebo) group. Treatment resistance (p: 0.389) was similar between the groups, indicating pure antibiotic resistance without any compliance problems. The number needed to treat for an additional beneficial outcome (NNTB) was 6.2 (CI 95%, 3.5 to 28.9) for probiotic use. CONCLUSION: In conclusion, adjuvant administration of probiotic (B. animalis subsp. lactis) in 2-week sequential H. pylori eradication therapy is associated with a higher H. pylori eradication rate, lower first week diarrhea-related treatment discontinuation rates, less common self-reported side effects, and higher treatment compliance.

Cirrhotic Ascites management via procalcitonin level and a new approach B-mode gray-scale histogram.

BACKGROUND/AIMS: To determine the role of serum procalcitonin levels and ascites/subcutaneous echogenicity ratio (ASER) in predicting ascites infection in hospitalized cirrhotic patients. MATERIALS AND METHODS: A total of 50 patients hospitalized because of cirrhosis-related ascites were included in this study. In these patients, 44% of ascites were infected (peritonitis), whereas 56% of ascites were sterile. These two groups were compared in terms of procalcitonin levels and ASER for predicting ascites infection. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of ASER, and the predicting outcome of ASER was compared with procalcitonin levels. RESULTS: The ASER values of the patients with the diagnosis of infected ascites were significantly higher than in those with the diagnosis of sterile ascites (p<0.001). ROC analysis was performed to determine the diagnostic ASER value for infected ascites. An ASER greater than 0.0019 determined peritonitis with 95.5% sensitivity and 100% specificity. A procalcitonin level greater than 0.05 determined peritonitis with 86.4% sensitivity and 75% specificity. Using ROC analysis, an ASER greater than 0.0019 [area under curve (AUC): 0.974, 95% confidence interval (CI) (0.884-0.999, p<0.001)] was a significantly better diagnostic marker than a procalcitonin level >0.5 mg/dL [AUC: 0.860, 95% CI (0.884-0.999, p<0.001) (p<0.045)]. CONCLUSION: According to our findings, the determination of ASER and serum procalcitonin levels seems to provide satisfactory diagnostic accuracy in differentiating ascites infections in hospitalized cirrhotic patients. ASER values significantly differentiate ascites infections better than procalcitonin levels.
