Risk factors for antibiotic-resistant bacteria colonisation in children with chronic complex conditions.

To assess drug-resistant bacterial colonisation rates and associated risk factors in children with complex chronic conditions admitted to a national reference unit in Spain. Cross-sectional study that included all children admitted to our unit from September 2018 to July 2019. Rectal swabs were obtained to determine multidrug-resistant Gram-negative bacilli (MR-GNB) colonisation, and nasal swab to determine S. aureus and methicillin-resistant S. aureus (MRSA) colonisation. Medical records were reviewed. 100 children were included, with a median of four complex chronic conditions. Sixteen percent had S. aureus colonisation, including two MRSA. S. aureus colonisation was associated with technology-dependent children, while being on antibiotic prophylaxis or having undergone antibiotic therapy in the previous month were protective factors. The prevalence of MR-GNB colonisation was 27%, which was associated with immunosuppressive therapy (aOR 31; 2.02-47]; p = 0.01), antibiotic prophylaxis (aOR 4.56; 1.4-14.86; p = 0.012), previously treated skin-infections (aOR 2.9; 1.07-8.14; p = 0.03), surgery in the previous year (aOR 1.4; 1.06-1.8; p = 0.014), and hospital admission in the previous year (aOR 1.79; [1.26-2.56]; p = 0.001). The rate of S. aureus nasal colonisation in this series was not high despite the presence of chronic conditions, and few cases corresponded to MRSA. Antibiotic prophylaxis, immunosuppressive therapies, history of infections, previous surgeries, and length of admission in the previous year were risk factors for MR-GNB colonisation.

Candidemia Diagnosis With T2 Nuclear Magnetic Resonance in a PICU: A New Approach.

OBJECTIVES: Early diagnosis of invasive Candida infections is a challenge for pediatricians, intensivists, and microbiologists. To fill this gap, a new nanodiagnostic method has been developed using manual application of T2 nuclear magnetic resonance to detect Candida species. The aim of this study was to evaluate, prospectively, the usefulness as a tool diagnosis of the T2Candida panel in pediatric patients admitted at the PICU compared with blood culture. DESIGN: This is a prospective, observational, and unicentric study to compare T2Candida results with simultaneous blood cultures for candidemia diagnose. SETTING: This study was carried out in a 1,300-bed tertiary care hospital with a 16-bed medical-surgical PICU. PATIENTS: Sixty-three patients from 0 to 17 years old were enrolled in this study, including those undergoing solid organ transplantation (kidney, liver, pulmonary, multivisceral, intestinal, and heart) and hematopoietic stem cell transplantation. MEASUREMENTS AND MAIN RESULTS: Seven patients were positive by the T2Candida test. Only two of them had the simultaneous positive blood culture. T2Candida yielded more positive results than blood cultures. CONCLUSIONS: T2Candida might be useful for the diagnosis of candidemia in PICUs. The prevalence of candidemia might be underestimated in this pediatric population. The use of this diagnostic tool in these units may help clinicians to start adequate and timely antifungal treatments.

Utility of FilmArrayⓇ ME panel for prompt Neisseria meningitidis detection in non-cerebrospinal fluid samples- A case report.

The FilmArrayⓇ Meningitis/Encephalitis Panel detects the 14 most frequent pathogens causing meningitis and/or encephalitis. The use of FilmArray ME with non-validated samples is seldom published in the literature. We describe the case of a 3-year-old child, diagnosed with acute meningoencephalitis, in whom the FilmArrayⓇ ME technique successfully identified Neisseria meningitidis in both skin biopsy and whole blood samples.

Acalculous Cholecystitis in a Pediatric Patient With Plasmodium Falciparum Infection: A Case Report and Literature Review.

Malaria has been associated with acute acalculous cholecystitis, a very uncommon complication in children. We present a 5-year-old girl, originally from Equatorial-Guinea, diagnosed with severe malaria with acute kidney injury, thrombocytopenia and acute acalculous cholecystitis. She was treated with intravenous quinine and clindamycin, plus cefotaxime and metronidazole with a full resolution without surgery.
