Abstract
AIMS To compare the efficacy of sitagliptin versus pioglitazone as add-on drugs in patients with poorly controlled diabetes with metformin and sulfonylureas. METHODS This is a randomized, open-label, parallel assignment clinical trial. Patients who had inadequate glycemic control [7% (53 mmol/mol) ≤ A1C < 11% (97 mmol/mol)] despite a minimum 6-month period of active treatment with metformin 2000 mg/day plus gliclazide 240 mg/day were enrolled in the study. HbA1C, fasting blood glucose (FBG), fasting plasma lipid parameters [total cholesterol (TC0, low-density lipoprotein cholesterol (LDL-C), triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C)], systolic and diastolic blood pressure (SBP, DBP), weight, waist circumference, and body mass index were measured at baseline and after 17, 34, and 52 weeks of treatment. Generalized estimating equation analysis was done to compare treatment groups for continuous efficacy parameters. RESULTS No significant difference in HbA1C reduction was observed between the treatment groups during the study course. (P = 0.149, adjusted P = 0.434; coefficient - 0.11 ± 0.08). The FBG (P = 0.032; coefficient 7.44 ± 3.48), HDL-C (P = 0.001; coefficient - 2.69 ± 0.83), TG (P = 0.027; coefficient 12.63 ± 5.71) and SBP (P < 0.001; coefficient 5.43 ± 1.26) changes from baseline, and weight gain were greater in the pioglitazone group. The mean changes in LDL-C and TC from baseline to week 52 were greater in the sitagliptin group (P = 0.034; coefficient - 7.40 ± 3.50, P = 0.013; coefficient - 7.16 ± 2.88, respectively). CONCLUSION Sitagliptin and pioglitazone were equally effective in improvement of HbA1C. There were some differences in terms of lipid indices, weight gain, and SBP. The current study confirmed that both sitagliptin and pioglitazone are effective treatment options and the decision should be made for each individual based on the baseline characteristics.

Abstract
BACKGROUND AND AIM The Helicobacter pylori cag pathogenicity island (cagPAI) is involved in delivery of CagA effector protein and peptidoglycan into host cells and also in IL-8 induction in the human gastric tissue. Diversity of cagPAI may affect disease status and clinical outcome of the infected patients. Our study was aimed to investigate diversity of this island and its intactness in Iranian patients to investigate possible associations between cagPAI integrity and pathological changes of the infected tissue. MATERIAL/PATIENTS AND METHODS Out of the 75 patients, H. pylori strains were obtained from 30 patients with severe active gastritis (SAG) (n=11), moderate chronic gastritis (CG) (n=14) and intestinal metaplasia/dysplasia (IM) (n=5). Intactness of the cagPAI was determined using 12 sets of primer pairs specific for functionally important loci of cagPAI by polymerase chain reaction (PCR). RESULTS The cagPAI positive strains were significantly observed in patients with SAG (52.4%) in comparison to those presenting CG (33.3%) and IM (14.3%). In addition, the presence of intact cagPAI was 87.5% in H. pylori strains isolated from patients with SAG, which was higher than those obtained from patients with CG (12.5%) or IM (0%). A significant increase in the frequency of cagα-cagY and cagW-cagT segments, as exterior proteins of the CagPAI, was illustrated in strains from SAG patients compared with those from patients with CG. CONCLUSIONS Overall, these results strongly proposed an association between the severity of histopathological changes and intactness of cagPAI in the gastric tissue of patients infected with H. pylori.

Abstract
Antimicrobial properties of plants essential oils (EOs) have been investigated through several observations and clinical studies which purpose them as potential tools to overcome the microbial drug resistance problem. The aim of this research is to study the antibacterial effect of two traditional plants essential oils, Thymus vulgaris and Eucalyptus globulus against clinical isolates of Methicillin resistant Staphylococcus aureus (MRSA) and other standard bacterial strains through disk diffusion and agar dilution methods. Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GC/MS) analysis examined the chemical composition of the oils. Results revealed both of oils to possess degrees of antibacterial activity against Gram (+) and Gram (-) bacteria. T. vulgaris EO showed better inhibitory effects than E. globulus essential oil. GC analysis of T. vulgaris resulted in thymol as the oil major compound whereas GC/MS assay exhibited eucalyptol as the most abundant constitute of E. globulus EO. These results support previous studies on these oils and suggest an additional option to treat MRSA infections. Clinical and further analytical trials of these data are necessary to confirm the obtained outcomes.
