[ 1 ] - Atorvastatin for Prevention of Amikacin-induced Electrolytes Imbalances; a Randomized Clinical Trial

Aminoglycosides are still widely used for treatment of gram-negative sepsis in critically ill patients. The most reported electrolyte abnormalities related to these drugs are hypokalemia, hypomagnesemia, and hypocalcemia. In this study potential benefit of atorvastatin in prevention of amikacin-induced electrolytes imbalances has been evaluated. In this trial 44 patients were assigned to the at...

[ 2 ] - Clinical, Paraclinical, and Antimicrobial Resistance Features of Community-Acquired Acute Bacterial Meningitis at a Large Infectious Diseases Ward in Tehran, Iran

In this study demographic, clinical, paraclinical, microbiological, and therapeutic features of patients with community-acquired acute bacterial meningitis admitted to a referral center for infectious diseases in Iran, have been evaluated. Medical records of adult (> 18 years) individuals with confirmed diagnosis of community-acquired bacterial meningitis during a 4-year period were retrospecti...

[ 3 ] - Approach to Anemia in Hospitalized Patients with Infectious Diseases; Is it Appropriate?

Anemia of chronic diseases (ACD) is a common problem in patients with infectious diseases and can influence the quality of life and patients' survival. Despite the clinical importance of ACD, data are still lacking regarding this problem in the infectious diseases. This study aimed to evaluate the prevalence, related factors, outcome and approaches to anemia in the infectious diseases ward. Thi...

[ 4 ] - Elevated Vancomycin Trough Concentration: Increased Efficacy and/or Toxicity?

Vancomycin susceptibility of methicillin-resistant Staphylococcus aureus has been changed over time and its average minimum inhibitory concentration increased from 1.5 to 1.75 mg/L. A recently published guideline by the American Society of Health Pharmacist recommended a daily dose of 15-20 mg/kg every 8 to 12 hours of vancomycin to achieve a trough concentration between 15-20 mg/L for treatmen...

[ 5 ] - Clinical Pharmacokinetics of Tacrolimus in Iranian Liver Transplant Recipients

Tacrolimus, a cornerstone of immunosuppressive therapy in solid organ transplantation, has a narrow therapeutic range with considerable inter-individual and intra-individual pharmacokinetic variability. To date, there is no information on the pharmacokinetics of tacrolimus in Iranian liver transplant recipients. This study was designed to determine pharmacokinetic properties of orally administe...

[ 6 ] - Reliability of Disk Diffusion Test Results for the Antimicrobial Susceptibility Testing of Nosocomial Gram-positive Microorganisms: Is E-test Method Better?

Disk diffusion test is the usual applicable method for assessing the antimicrobial susceptibility pattern in most institutions and hospitals. The aim of this study was to determine the reliability of resistant-reported results of disk diffusion test for 6 routinely used antibiotics against Gram-positive microorganisms of nosocomial origin, using E-test method. Over a 1-year period, clinic...

[ 13 ] - Heparin Resistance During and Post-Intravenous Nitroglycerin Infusion

Nitroglycerin has been reported to reduce activated partial thromboplastin time (aPTT) values in patients treated with concurrent heparin and nitroglycerin. However, studies have yielded conflicting results. To determine whether intravenous nitroglycerin alters the anticoagulant effect of heparin, we prospectively evaluated twenty patients admitted for coronary angioplasty by measurin...

[ 14 ] - Production of vitamin D3 enriched biomass of Saccharomyces cerevisiae as a potential food supplement: evaluation and optimization of culture conditions using Plackett–Burman and response surface methodological approaches

Vitamin D deficiency causes osteoporosis, osteopenia, fractures, rickets and more recently is linked with some chronic illnesses such as cancer. Because of the safety and probiotic properties of the yeast Saccharomyces cerevisiae, we hypothesized that yeast cells enriched with cholecalciferol (vitamin D3) could represent a solution for prevention or treatment of vitamin D deficiency. In this st...

[ 16 ] - Evaluation of Anti-oxidant and Anti-biofilm Activities of Biogenic Surfactants Derived from Bacillus amyloliquefaciens and Pseudomonas aeruginosa

Biosurfactants, the microbial originated surface active agents, can modify the physicochemical properties of surfaces and reduce the bacterial adhesion via changing bacterial adhesion interactions on surfaces. They were also able to block oxidative chain reactions and might show antioxidant properties. The goal of this study was to evaluate the antioxidant and antibiofilm activities of biosurf...
