| 1 | Organisms causing spontaneous bacterial peritonitis in children with liver disease and ascites in Southern Iran显示文摘AIM: To determine the causative agents of spontaneous bacterial peritonitis (SBP) in children with liver disease and ascites in our center.METHODS: During a 2.5 year period, from September 2003 to March 2006, 12 patients with 13 episodes of SBP were studied. In all cases at the time of admission serum albumin and glucose, urinalysis and urine culture was performed. Analysis [white blood cell (WBC) count with differential, albumin, glucose], gram stain, culture by BACTEC method and antibiogram was done on ascitic fluids. Abdominal paracentesis was repeated after 48 h of antibiotic therapy for bacteriologic assay. The patients were followed for at least three months in a gastroenterology clinic. RESULTS: There were 7 girls (58%) and 5 boys (42%) with a median age of 5.2 years (range, 6 mo to 16 years). All cases had positive ascitic fluid culture. Gram stain was positive in 5 (38.5%) of them. The isolated organisms were S. pneumoniae in 5 (38.5%), E. coli in 2 (15.3%), S. viridans in 2 (15.3%), and K. pneumoniae, H. influenza, Enterococci, and nontypable Streptococcus each in one (7.7%). All of them except Enterococci were sensitive to ciprofloxacin and ceftriaxone. All ascitic fluid cultures were negative after 48 h of antibiotic therapy. CONCLUSION: S. pneumoniae is the most common cause of SBP in the pediatric age group and we recom-mend a third generation cephalosporine (e.g., Ceftriax-ione or Cefotaxime) for empirical therapy in children with SBP. | Mahmood Haghighat Seyed Mohsen Dehghani Abdolvahab Alborzi Mohammad Hadi Imanieh Bahman Pourabbas Mehdi Kalani | 2006 | World Journal of Gastroenterology2006，12，36： | 4 |
| 2 | Antimicrobial susceptibility of Helicobacter pylori strains isolated from patients in Shiraz, Southern Iran显示文摘AIM: To improve our understanding of Iranian regional variation in Helicobacter pylori (H. pylori ) antibiotic resistance rates to find the best antibiotic therapy for eradication of H. pylori infections.METHODS: A total of 266 patients undergoing endoscopy in Shiraz, Southern Iran, were included in this study. H. pylori strains were isolated from antral biopsies by culture and confirmed by the rapid urease-test and gram staining. Antibiotic susceptibility of H. pylori isolates was determined by E-test.RESULTS: A total of 121 H. pylori strains were isolated, 50 from male and 71 from female patients. Data showed that 44% (n = 53), 20% (n = 24), 5% (n = 6), and 3% (n = 4) of all strains were resistant to the antibiotics metronidazole, amoxicillin, clarithromycin, and tetracycline, respectively. When the antibiotics were considered together we found 11 sensitivity patterns for the strains. Resistance to metronidazole was significantly higher in female than in male patients (P < 0.05). In about 71% of the metronidazole-resistant isolates, the minimum inhibitory concentrations (MICs) exceeded 256 μg/mL.CONCLUSION: We found a moderate rate of primary resistance to metronidazole. However, a high MIC (> 256 mg/L) which was found in 71% of the isolates is considerable. In the case of amoxicillin, an increased resistance rate of 20% is worrying. Resistance to clarithromycin and tetracycline is also emerging among the H. pylori strains in our region. | Shohreh Farshad Abdolvahab Alborzi Aziz Japoni Reza Ranjbar Kazem Hosseini Asl Parisa Badiee Maneli Amin Shahidi Marziyeh Hosseini | 2010 | World Journal of Gastroenterology2010，16，45： | 1 |
