Prevalence of E. coli ST131 among Uropathogenic E. coli Isolates from Iraqi Patients in Wasit Province, Iraq

The emergence of Escherichia coli sequence type 131 (E. coli ST131) clone represents a major challenge to public health globally, since this clone is reported as highly virulent and multidrug-resistant, thus making it successfully disseminated worldwide. In Iraq, there is no previous study dealing with this important clone, so this project was suggested to investigate its presence within uropathogenic E. coli (UPEC) from Iraqi patients in Wasit Province. A total of 112 UPEC isolates from cases of acute urinary tract infection (UTI) were analysed for phylogenetic groups by quadruplex PCR; then, these isolates were investigated for E. coli ST131 clone by both conventional and real-time PCR procedures. The antibiotic susceptibility test was performed by the disk diffusion method. The results revealed that, out of 112 UPEC isolates, 38 (33.9%) belonged to phylogroup B2. For conventional PCR, 92.1% (35/38) of B2 E. coli isolates were positive for E. coli ST131, of which 34 were O25b-ST131 strain and 1 was O16-ST131 strain. However, serogroups O25b and O16 represented 17.1% and 2.8%, respectively. By RT-PCR assay, 15.1% (17/112) and 44.7% (17/38) of total and B2 E. coli isolates were confirmed as being E. coli ST131, respectively. The highest resistance rates of E. coli ST131 isolates were against the β-lactams, while low resistance rates were against amikacin, nitrofurantoin, and gentamicin. Fortunately, all isolates were susceptible to carbapenems. Moreover, 52.9% (9 out of 17) of E. coli ST131 isolates were MDR. In conclusion, the presence of E. coli ST131 among UPEC isolates from Iraqi patients is confirmed with high resistance to most antimicrobials included in this study.

Laparoscopic resection of a bladder diverticulum in children

Introduction. Recently, there have been publications devoted to laparoscopic removal of a bladder ear. The article sums up the multi-center experience in laparoscopic diverticulectomy.Materials and methods. Case histories of 30 children who underwent surgeries from 2012 to 2019 in 7 outpatient clinics were analyzed retrospectively. 22 boys (73.3%) and 8 girls (26.7%) were operated. At the time of the surgery, the mean age of the patients was 53.5 months. 15 (50.0%) children had right-sided diverticulum, 13 (43.3%) children suffered from left-sided one, and 2 had bilateral diverticulum (6.7%). The disease onset was presented by acute urinary tract infection in 25 (83.3%) children and urination dysfunction in 5 (16.7%). The laparoscopic access technique was used in all children. An isolated diverticulum was excised and the wall of the urinary bladder was restored. When the diverticulum was combined with a vesicoureteral reflux or ureterovesical anastomosis, ureteral reimplantation was added. Results. No conversions were found during the laparoscopy. Following the surgery, 3 (10.0%) children developed stent-associated pyelonephritis. No patient had complications during the observation that lasted from 6 months to 6 years. Conclusion. Laparoscopic technique is an effective and safe approach of treating a bladder ear in children.

Epidemiology and genotypic characterisation of dissemination patterns of uropathogenicEscherichia coliin a community

To characterise the dissemination patterns of uropathogenicEscherichia coli(UPEC) in a community, we conducted a study utilising molecular and fundamental descriptive epidemiology. The subjects, consisted of women having community-acquired acute urinary tract infection (UTI), were enrolled in the study from 2011 to 2012. UPEC isolates were subjected to antibacterial-susceptibility testing, O serogrouping, phylotyping, multilocus-sequence typing with phylogenetic-tree analysis and pulsed-field-gel electrophoresis (PFGE). From the 209 unique positive urinary samples 166 UPEC were isolated, of which 129 were fully susceptible to the tested antibiotics. Of the 53 sequence types (STs), the four most prevalent STs (ST95, ST131, ST73 and ST357) accounted for 60% of all UPEC strains. Antimicrobial resistance was less frequently observed for ST95 and ST73 than for the others. A majority of rare STs and a few common STs constituted the diversity pattern within the population structure, which was composed of the two phylogenetically distinct clades. Eleven genetically closely related groups were determined by PFGE, which accounted for 42 of the 166 UPEC isolates, without overt geo-temporal clustering. Our results indicate that a few major lineages of UPEC, selected by unidentified factors, are disseminated in this community and contribute to a large fraction of acute UTIs.

The Efficacy and Safety Of Using Hydrochlorothiazide As Adjuvant Therapy In Pediatric Urinary Tract Infections

Background: Acute urinary tract infection is a common bacterial infection causing illness in infants and children. At age of seven, 8% of girls and 2% of boys will have at least one episode. Although drinking water and using home remedies are known to help to flush away bacteria and keeps them from sticking to the bladder wall, researches to test the efficacy and safety of hydrochlorothiazide's diuretic effect as adjuvant to the antibiotics in pediatric age groups are lacking, and so this research was to address this subject. Objectives: To assess the effectiveness and the safety of hydrochlorothiazide as adjuvant therapy to the antibiotics in treating acute urinary tract infection in pediatric age group. Type of the study: Case-control prospective study. Methods: The study was done including eight hundred sixty five patients ((In_ & Out_ patients)): The patients included were aged from few hours (neonates) to 16 years old, Those who attended three pediatric hospitals- department of nephrology of:The Central Child Teaching Hospital,Al- Elwyia Pediatric Hospital andIbn Al-Baladi Hospital Results: 215 patients in group 1 ((97.3%)) presented with cystitis and 6 patients ((2.7%)) with pyelonephritis, And In group 2, 243 ((96.4%)) with cystitis and 9 patients ((3.6%)) with pyelonephritis.The urine cultures were negative in ((76.4, 80.1, 85.9,95.0 percentages of patients)) after ((10 days, 1 month, 3 months and 6 months respectively)) in group1 vs. ((60.3, 68.60,75.8,85.3 )) after the same periods in group 2 ((p-value=0.04 at 10 days, 0.03 at 1month, 0.04 at 3 month and 0.02 at 6month)). Conclusions: This research had concluded that 5 days of treatment with antibiotics and hydrochlorothiazide were effective and safe to treat children with urinary tract infection. Hydrochlorothiazide (as a diuretic and hypocalciuric agent) adjuvant to the antibiotics in pediatrics was safe and effective to: Decrease duration of treatment and hospitalization days, Improve clinical responses to antibiotics and Decrease risk of complications of UTI.

Treatment of Acute Urinary Tract Infection in Children with Pipemidic Acid

Urinary tract infection in children is still an important problem in uronephrology. The disease.tends to develop recurrently and results in chronic progressive renal disease in the future. Pipemidic acid is a bactericidal quinolone derivate, with a wide spectrum against gram positive and negative bacteria. Compared with nalidixic acid, pipemidic acid proves to be more effective against Pseudomonas, E. coli, Alkali genes and Salmonella. Thirty one cases with acute urinary tract infection had been studied descriptively. The etiology revealed as follows: E. coli (45.2%), Alkaligenes (16.2%), Enterobacter (9.6%), Staphylococcus (9.6%), Pseudomonas (9.6%), Paracolon (6,5%), and Proteus (3.3%). Pipemidic acid was administered orally to these patients, 15-20 mg/kg/day divided in 2 equal doses for 10 days. Bacteriological examinations was repeated on the 6th day and 11th day treatment. The result revealed that on the 6th day of treatment, in 27 patients (87, 09%) there was no bacteriuria while on the 11th day the urine of 29 patients (93.54%) were sterile. In conclusion, a 5 day treatment of acute urinary tract infection in children with pipemidic acid is quite effective.
