Role of micro-RNA132 and its long non coding SOX2 in diagnosis of lupus nephritis.

BACKGROUND: The skin and the kidney are commonly affected in systemic lupus erythematosus (SLE) with similar molecular mechanisms. Although clinical indicators of renal injury in SLE are fairly uncontroversial, few biomarkers are reliable. The role of micro-RNAs (mi-RNAs) in lupus nephritis (LN) pathogenesis has been investigated to help in early diagnosis. PURPOSE: The aim of work is to evaluate miRNA132 and SOX2 expressions in SLE Egyptian patients; with and without nephritis, and the relation between miRNA132 and its long non-coding gene SOX2 in both patients groups. RESEARCH DESIGN: This is a case-control study involving 100 SLE patients with and without LN (LN and non-LN groups), and 50 age-and sex-matched healthy controls. The study was carried out to detect miRNA132 and SOX2 expression by quantitative Real-Time Polymerase chain reaction methods. The SLE disease activity index (SLEDAI) was assessed. RESULTS: SLEDAI increased in LN compared to non-LN. Micro-RNA132 expression was significantly increased in patient groups compared to controls (p<0.01) and increased in LN more than non-LN group (p<0.001). SOX2 significantly decreased in patient groups compared to controls (p<0.001), and was more in LN compared to non-LN group (p<0.001). There was a negative correlation between miRNA132 and SOX2 expression in both patient groups (p<0.001). CONCLUSION: miRNA132 and SOX2 may play a role in SLE activity and help in the early non-invasive diagnosis of LN.

Comparative Study of CTX-M-15 Producing Escherichia coli ST131 Clone Isolated from Urinary Tract Infections and Acute Diarrhoea.

BACKGROUND AND PURPOSE: The alarming increase in the prevalence of CTX-M-15 extended-spectrum ß-lactamase (ESBL) producing E. coli has been significantly linked to the clonal expansion of emerging sequence type (ST131). This study aimed to screen for the O16/O25-ST131 clones among different phylogenetic types of E. coli strains isolated from urinary and diarrhoeal samples. METHODS: A total of 205 E. coli strains isolated from patients with UTI and acute diarrhoea were investigated by phenotypic and genotypic methods for ESBL identification. Molecular methods were used for identification of O25/O16-ST131 clone and phylogenetic typing of E. coli isolates. RESULTS: O25-ST131 clone was detected in 89/105 (84.8%) and 47/100 (47%) of urinary and intestinal E. coli isolates, respectively, with a significant difference (P-value<0.001). There was a significant high rate of occurrence of ESBLs, MDR, and antibiotic resistance to most antibiotic classes among O25-ST131 than non-O25-ST131 isolates. CTX-M-15 gene was detected in 64/71 (90%) of ESBLs producing intestinal isolates and 54/79 (68.4%) of urinary ESBLs producing isolates. The O25-ST131 clone was reported among all phylogenetic groups. The O16-ST131 clone serotype was not detected in the study isolates. CONCLUSION: High prevalence of the O25-ST131 clone was reported among extraintestinal and intestinal E. coli isolates. First detection of the O25-ST131 clone among phylogenetic groups other than group B2 draws attention of the ability of this clone to transfer among commensal groups. An increasing in the prevalence of CTX-M-15 among E. coli strains especially of intestinal origin is alarming as the intestine is the main reservoir for ExPEC strains causing UTI.

The impact of structured diabetes education on glycemic control during Ramadan fasting in diabetic patients in Beni Suef, Egypt.

AIMS: Ramadan is a holy month for the Muslim community. Fasting Ramadan is directed by a systematic alteration in eating habits, sleeping times, and daily physical activities that optimize blood glucose levels. This study aims to evaluate the effects of structured education on safe fasting among diabetic patients. METHODS: This study included diabetic patients with eligibility for the Ramadan fast. The control group included 494 patients who received standard diabetes education, while the intervention group included 407 patients who attained structured diabetes education. The patients were required to register their responses following the written, structured questionnaires before and after Ramadan fasts. In addition, patients were advised to keep a log of their hypoglycemic episodes. RESULT: This study showed that structured diabetes education improved the blood glucose levels/glycemic control and outcomes of patients during their Ramadan fasting. The structured diabetes education helped reduce the incidence of hypoglycemic events and hyperglycemic crises. It also increased the acceptance and frequency of blood sugar level measurements among patients during Ramadan. CONCLUSION: The standard diabetes management plan should include structured diabetes education measures to improve outcomes effectively. The providers should screen the patients with diabetes before Ramadan and educate them to improve their safe fasting practices.
