Pediatric community acquired urinary tract infections due to extended-spectrum beta-lactamase versus non-extended-spectrum beta-lactamase producing bacteria.

BACKGROUND: This study aimed to evaluate the demographics, clinical characteristics, risk factors, and antibiotic resistance of pediatric community-acquired urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing and non-ESBL-producing uropathogens. METHODS: This retrospective study was conducted at a tertiary care hospital in Saudi Arabia, among children aged between 0 and 14 years, with a culture-proven diagnosis of community-acquired UTI between February 2019 and September 2021. Patients were divided into two groups based on whether or not their UTI was caused by ESBL-producing bacteria. RESULTS: A total of 383 patients with community-acquired UTI were evaluated. Escherichia coli was detected in 72.6% of cultures. Extended-spectrum beta-lactamase-producing organisms were responsible for 35.7% of UTI episodes. Of these 69% and 31% were caused by E. coli and Klebsiella pneumoniae, respectively. There were no significant differences between the two groups with regard to clinical presentation or urine analysis. The resistance rates in the ESBL-producing group were 39.4% for amoxicillin/clavulanic acid, 65.7% for ciprofloxacin, 72.3% for co-trimoxazole, 32.8% for nitrofurantoin, 21.2% for gentamicin, and 0.7% for amikacin and carbapenems. In the non-ESBL-producing group, it was 22.4% for amoxicillin/clavulanic acid, 22.4% for ciprofloxacin, 38.2% for co-trimoxazole, 23.6% for nitrofurantoin, 6.1% for gentamicin, and zero for amikacin and carbapenems. The presence of renal abnormalities (p = 0.014) and male gender (p = 0.026) were determined to be independent risk factors for ESBL UTIs. CONCLUSIONS: Recognizing risk factors and antibiotic resistance for ESBL-producing bacteria may aid in tailoring an antibiotic regimen for pediatric patients at high risk of ESBL-UTIs.

Antibiotic resistance patterns of pediatric community-acquired urinary tract infections in a tertiary care center in Jeddah, Saudi Arabia.

INTRODUCTION: Urinary tract infections (UTIs) are common in children. UTIs can lead to serious and permanent damage to the urinary tract if treatment is delayed or insufficient, particularly in repeated infections. Knowledge of antibiotic resistance trends aids in the selection of appropriate empiric antibiotics. There is limited data regarding this in Saudi Arabia. This study aimed to investigate uropathogens and their antibiotic resistance patterns in the pediatric community in a tertiary care center. METHODOLOGY: The study population included children aged 0 to 14 years old who had culture-proven UTIs evaluated in the Department of Pediatrics, King Abdulaziz University Hospital in Jeddah, Saudi Arabia from February 2019 to September 2021. RESULTS: Out of 510 UTI episodes, Escherichia coli (54.5%) was the predominant causative pathogen. Of the total episodes, 137 (26.8%) were caused by extended spectrum beta-lactamase (ESBL) producers. In general, the highest resistance was observed against ampicillin (73.2%), cefazolin (54.6%), co-trimoxazole (46%), and cefuroxime (40.6%), whereas amikacin (0.4%), imipenem (0.8%), and meropenem (0.8%) showed the lowest rates of resistance. CONCLUSIONS: Antibiotic resistance is a major concern worldwide due to misuse of antibiotics and subsequent rise of multidrug resistant organisms. Our findings highlight the rise in antibiotic resistance, particularly in E. coli strains. Furthermore, ESBL-producing bacteria were responsible for approximately one-third of UTIs. Our study emphasizes the importance of local antibiograms for pediatric community-acquired infections, as it guides clinicians in every center in the choice of appropriate empiric antibiotic treatment.

Impact of coronavirus disease 2019 in a child who underwent ventricular septal defect device closure: a case report.

BACKGROUND: Studies about the incidence and severity of coronavirus disease 2019 (COVID-19) in children are still significantly lower than those in adults. Moreover, data on the effect of COVID-19 in children with congenital heart disease (CHD) are limited. To the best of our knowledge, this study first reported mortality in a child with CHD who acquired COVID-19. CASE SUMMARY: A 16-month-old boy presented to the emergency department due to shortness of breath, fever, cough, and poor oral intake. He tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). He required mechanical ventilation for rapidly progressing respiratory failure. The patient had a large mid-muscular ventricular septal defect (VSD) that was closed percutaneously at the age of 13 months. Moreover, we followed his hospital sequelae from admission to death. DISCUSSION: This child had multiple risk factors, including malnutrition and persistent pulmonary hypertension (PH) after late closure of the VSD. The pre-existing PH could have been aggravated by the lung condition associated with COVID-19 and the respiratory failure triggered by SARS-CoV-2 infection. The patient presented with ventricular systolic dysfunction, elevated troponin serum levels and newly developed trifascicular block, which were indicative of myocardial injury. The elevated inflammatory markers and multi-organ dysfunction seem to corroborate multisystem inflammatory syndrome in children, which was described recently among paediatric patients with COVID-19.

Clinical characteristics and outcomes of children with COVID-19 in Saudi Arabia.

OBJECTIVES: To determine the demographic and clinical characteristics, underlying comorbidities, and outcomes of children with coronavirus disease 2019 (COVID-19) infection. METHODS: In this retrospective study, we reported 62 pediatric patients (age <14 years) with confirmed COVID-19 between March 2 and July 1, 2020, at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. RESULTS: Comorbid conditions, including cardiac, neurological, respiratory, and malignant disorders, were reported in 9 patients (14.5%). The most prominent presenting complaints were fever (80.6%) and cough (48.4%). Most of our patients (80.6%) had mild disease, 11.3% had moderate disease, and 8.1% exhibited severe and critical illness. Twenty-one patients (33.9%) were hospitalized, with 4 patients (6.5%) admitted to the pediatric intensive care unit, and 3 (4.8%) patients died. CONCLUSION: All pediatric age groups are susceptible to COVID-19, with no gender difference. COVID-19 infection may result in critical illness and even mortality in subsets of pediatric patients.

Dominance of the ON1 Genotype of RSV-A and BA9 Genotype of RSV-B in Respiratory Cases from Jeddah, Saudi Arabia.

Human respiratory syncytial virus (HRSV) is a main cause of hospital admission for lower respiratory tract infection. In previous studies from Saudi Arabia, higher prevalence of the NA1 genotype in group A was observed from Riyadh and Taif. This study recruited respiratory cases from Jeddah during January to December, 2017. RSV represented 13.4% in the recruited cases with 64% of them belonging to group A and 36% to group B. All group A cases in this study were ON1 type characterized by duplication of 72 nucleotides, 24 amino acids in the C-terminal in the second hypervariable region of the G gene. In addition, for group B all of the cases were clustered under BA9, which had uniquely characterized as duplication of 60 nucleotides in the G protein. Our sequences showed similarity with earlier sequences from Saudi Arabia, Kuwait, Thailand, South Africa, Spain, the USA and Cyprus. Some amino acid substitutions in the investigated sequences would cause a change in potential O-glycosylation and N-glycosylation profiles from prototype ON1. The predominance of the ON1 and BA9 genotype of RSV-A in Jeddah compared to previous Saudi studies showing predominance of the NA1 genotype for group A. This difference in genotype prevalence could be due to fast spread of the ON1 genotype worldwide or due to the flux of travelers through Jeddah during hajj/umrah compared to Riyadh and Taif. This shift in genotype distribution requires continuous surveillance for genetic characterization of circulating respiratory infections including RSV. These findings may contribute to the understanding of RSV evolution and to the potential development of a vaccine against RSV.
