ABSTRACT
BACKGROUND: This study was designed to examine the possible efficacy of the probiotic strain Lactobacillus acidophilus LB (Lacteol Fort) on attention-deficit/hyperactivity disorder (ADHD) symptomatology and evaluate its influence on cognition function. METHODS: In this randomized controlled trial, 80 children and adolescents with ADHD diagnosis, aged 6-16 years, were included. The participants were randomly assigned to two groups: one group received probiotics plus atomoxetine, whereas the other group received atomoxetine only. ADHD symptomatology was assessed using the Conners Parent Rating Scale-Revised Long Version (CPRS-R-L) and Child Behavioral Checklist (CBCL/6-18). The participants were evaluated for their vigilance and executive function using Conner's Continuous Performance Test (CPT) and Wisconsin Card Sort Test (WCST). Both groups were assessed at the beginning of the study and the end of the twelve weeks. RESULTS: The probiotic group comprised 36 patients, whereas the control group comprised 40 patients in the final analysis after four patients dropped out of the trial. After 3 months of probiotic supplementation, a significant improvement in the CPRS-R-L and CBCL total T scores was observed compared with those in the control group (p = 0.032, 0.024, respectively). Additionally, the probiotic group demonstrated improved focus attention (target accuracy rate and omission errors;p = 0.02, 0.043, respectively) compared with the control group. An analysis of the Wisconsin Card Sorting Test (WCST) performance demonstrated that the probiotic group had significantly lower perseverative (p = 0.017) and non-perseverative errors (p = 0.044) but no significant differences compared to the control group. CONCLUSION: Lactobacillus acidophilus LB supplementation combined with atomoxetine for 3 months had a beneficial impact on ADHD symptomology and a favorable influence on cognitive performance. As a result, the efficacy of probiotics as an adjunctive treatment for managing ADHD may be promising. TRIAL REGISTRATION: ClinicalTrials.gov (identifier: NCT04167995). Registration date: 19-11-2019.

BACKGROUND: This study was conducted by considering the vital role of Vascular Endothelial Growth Factor (VEGF) in the development of Diabetic Retinopathy (DR) on the one hand and the frequent association between Subclinical Hypothyroidism (SCH) and DR on the other hand. OBJECTIVE: The present study was proposed to explore the possible role of VEGF in the relation between SCH and DR; thus, we investigated the relationship between SCH and VEGF levels in patients with DR. METHODS: Two hundred patients with DR were recruited in this study [100 patients with Proliferative Diabetic Retinopathy (PDR) and 100 patients with Non-Proliferative Diabetic Retinopathy (NPDR)]. Patients with DR were divided into 2 groups according to thyroid function, patients with SCH or those with euthyroidism. Patients were subjected to careful history taking and underwent clinical and ophthalmological examination. Fasting blood glucose, glycosylated hemoglobin, fasting insulin, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), TSH, FT4, FT3, VEGF, and thyroid volume were assessed. RESULTS: Among all the studied patients, 21.5% (43/200) had SCH. DR patients with SCH had older age, longer diabetes duration, and higher HbA1c, HOMA-IR, and VEGF than those with euthyroidism. The frequency of PDR in patients with SCH was 72.1% (31/43) and 43.9% (69/157) in those with euthyroidism, whereas the frequency of NPDR in patients with SCH was 27.9 (12/43) and 56.1% (88/157) in those with euthyroidism (P 0.003). In multivariate analysis, PDR, HOMA- IR, and VEGF levels were the significant predictor variables of SCH. CONCLUSION: Increased VEGF levels may be implicated in the relationship between SCH and DR.

We aimed to study the relation between both bacterial colonization of the uterine endometrium & endometrial miR-17-5p levels and endometriosis, and then to evaluate endometrial miR-17-5p as a biomarker of endometriosis. A comparative observational study was carried over 51 endometriosis patients and 51 controls admitted into Obstetrics and Gynecology department, Mansoura Faculty of Medicine. Endometrial tissue samples were collected and aimed for bacterial culture and identification of resulting organisms besides estimation of tissue levels of microRNA-17-5p by quantitative real time PCR. G. vaginalis, S. agalactiae, S. aureus, Mobiluncus and E. coli were associated with endometriosis. MicroRNA-17-5p was up-regulated in endometriosis patients (P value was <0.0001*). Its sensitivity and specificity were 90% and 76.5%. MiR-17-5p showed higher results in culture positive than negative cases. On studying the relation between the positivity of endometrial tissue culture and miR-17-5p and so endometriosis, P value was <0.0001*. We concluded that G. vaginalis, S. agalactiae, S. aureus, Mobiluncus and E. coli were associated with development of endometriosis. Endometrial miR-17-5p was elevated in association to positive detection of bacterial species. MiR-17-5p might be a bio- marker of endometriosis.

BACKGROUND: Diffusion-weighted magnetic resonance imaging has shown promise in the detection and quantiï¬cation of hepatic ï¬brosis. In addition, the liver has numerous endogenous micro-RNAs (miRs) that play important roles in the regulation of biological processes such as cell proliferation and hepatic fibrosis. AIM: To assess diffusion-weighted magnetic resonance imaging and miRs in diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C. METHODS: This prospective study included 208 patients and 82 age- and sex-matched controls who underwent diffusion-weighted magnetic resonance imaging of the abdomen, miR profiling, and liver biopsy. Pathological scoring was classified according to the METAVIR scoring system. The apparent diffusion coefficient (ADC) and miR were calculated and correlated with pathological scoring. RESULTS: The ADC value decreased significantly with the progression of fibrosis, from controls (F0) to patients with early fibrosis (F1 and F2) to those with late fibrosis (F3 and F4) (median 1.92, 1.53, and 1.25 × 10-3 mm2/s, respectively) (P = 0.001). The cut-off ADC value used to differentiate patients from controls was 1.83 × 10-3 mm2/s with an area under the curve (AUC) of 0.992. Combining ADC and miR-200b revealed the highest AUC (0.995) for differentiating patients from controls with an accuracy of 96.9%. The cut-off ADC used to differentiate early fibrosis from late fibrosis was 1.54 × 10-3 mm2/s with an AUC of 0.866. The combination of ADC and miR-200b revealed the best AUC (0.925) for differentiating early fibrosis from late fibrosis with an accuracy of 80.2%. The ADC correlated with miR-200b (r = - 0.61, P = 0.001), miR-21 (r = - 0.62, P = 0.001), and miR-29 (r = 0.52, P = 0.001). CONCLUSION: Combining ADC and miRs offers an alternative surrogate non-invasive diagnostic tool for diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.

BACKGROUND/AIMS: Chronic hepatitis C (CHC)-related mortality generally results from cirrhosis and subsequent complications. We aimed to investigate the potential role of plasma bile acid levels and ABCB11 1331T > C (V444A, rs2287622) (ATP-binding cassette subfamily B, member 11) gene polymorphism in fibrosis prediction in CHC genotype 4 patients. MATERIALS AND METHODS: This case control study included 85 healthy control and the following 225 subjects: 170 adult patients infected with hepatitis C virus (HCV) and categorized into three groups according to liver biopsy; no fibrosis group (F0) (n=33), early fibrosis group (F1-F2) (n=61), and advanced fibrosis group (F3-F4) (n=76). Fasting bile acid levels, hepatitis C virus (HCV) genotyping, and ABCB11 1331T > C gene polymorphism were assessed. RESULTS: The frequency of the variant homozygote genotype CC in advanced fibrosis was significantly higher than that in early fibrosis (48.7% vs. 36.1%) (odd ratio, OR =2.58; 95% confidence interval, CI=1.07-6.20; p=0.03). C allele was significantly represented in advanced fibrosis (65.8%) compared with that in early fibrosis (51.6%) (OR=1.80, 95% CI=1.10-2.93, p=0.01). A significant elevation of plasma bile acid levels in advanced fibrosis was observed compared with those in early fibrosis (p≤0.001). Receiver operating characteristic curve for plasma bile acid levels at cutoff value of 75.5 µmol/L had a 59% specificity and 97.4% sensitivity as a predictor of advanced hepatic fibrosis (AUROC=0.78%). CONCLUSION: We concluded that Egyptian patients having chronic hepatitis C genotype 4 with CC genotype of ABCB11 SNP 1331T > C and high plasma bile acid levels at cutoff value of 75.5 µmol/L were associated with advanced hepatic fibrosis.

PURPOSE: This study aimed to examine the impact of combined supplementation of fish oil (FO) with antioxidants like wheat germ oil (WGO) on mineral-bone and inflammatory markers in maintenance HD patients. METHODS: This randomized, double-blind, placebo-controlled trial involved 46 HD patients who were randomly assigned into two groups to receive daily 3000 mg of FO [1053 mg omega-3 fatty acids (ω-3 FAs)] plus 300 mg of WGO [0.765 mg vitamin E] or placebo for 4 months. Blood concentrations of hemoglobin (Hgb), white blood cells, mineral-bone parameters including serum calcium (Ca), phosphorus, calcium-phosphorus product, parathyroid hormone, alkaline phosphatase, and osteoprotegerin and serum concentrations of inflammatory markers including high-sensitivity C-reactive protein, ferritin, and uric acid were measured before and after the intervention. RESULTS: Eighty-seven percentage of patients in each group completed the study. The mean serum Ca levels increased significantly in the supplemented group at the end of study (p = 0.0016), and this increment was also significant as compared to placebo group (p = 0.0418). No significant alterations were observed in the other measured parameters within each group during the study (as p values were >0.05). CONCLUSION: FO plus WGO supplementation showed beneficial effect on serum Ca levels of HD patients without any statistically significant effect on other mineral-bone and inflammatory markers. Further investigations are required to confirm it.

The rate of liver fibrosis progression in chronic hepatitis C (CHC) patients is highly variable and affected by different factors. This study aimed to assess the role of cirrhosis risk score (CRS) based on 7 genetic variants (7 single-nucleotide polymorphisms [SNPs]) and host factors (age and sex) in the prediction of the rate of fibrosis progression in CHC. Duration of infection was determined in 115 patients. The fibrosis progression rate (FPR) per year was calculated as the ratio between fibrosis stage and the duration of infection. SNP genotyping were performed and CRS was determined based on it. FPR was significantly elevated in patients who acquired infection at age >40 years versus those who acquired infection at 30-40 years and those who acquired infection at <30 years. Median FPR was significantly higher in males than females (0.17 vs. 0.15) with P = 0.001. CRS value ≥0.8 is predictive of patients with high risk for cirrhosis, and CRS value <0.5 is predictive of patients with low risk for cirrhosis. There was significant positive correlation between CRS and FPR (P ≤ 0.001). CRS based on 7 SNPs at cutoff value ≥0.8, age at infection >40 years, and male sex are predictors of higher FPR.
