Carbapenem-resistant Enterobacteriaceae (CRE) are an emerging problem in the paediatric population worldwide with high mortality rates in bloodstream infection (BSI).
To evaluate predictors of 30 day ...mortality in CRE BSI in a paediatric cohort.
A retrospective observational single-centre study (December 2005-August 2018) was conducted. Cases of CRE BSI in children 0 to 16 years were included. Microbiological identification (MALDI Biotyper) and antimicrobial susceptibility testing (Vitek2® and MicroScan panel NBC44) according to EUCAST breakpoints were performed. PCR OXVIKP® was used to confirm carbapenemase genes (OXA-48, VIM, KPC, NDM). Demographic characteristics, underlying diseases, source of bacteraemia, antimicrobial therapy and outcomes were collected from medical records. Survival analysis to establish predictors of 30 day mortality was performed.
Thirty-eight cases were included; 76.3% were hospital-acquired infections and 23.7% related to healthcare. All patients had at least one underlying comorbidity and 52.6% were recipients of an organ transplant. VIM carbapenemase was the predominant mechanism (92.1%). Previous CRE colonization or infection rate was 52.6%. Intestinal tract (26.3%) and vascular catheter (21.1%) were the most common sources of infection. Crude mortality within 30 days was 18.4% (7/38); directly related 30 day mortality was 10.5%. Conditions associated with an increment in 30 day mortality were intensive care admission and inadequate empirical therapy (P < 0.05). Combination-antibiotic targeted treatment and a low meropenem MIC were not related to improved survival.
CRE BSI mortality rate is high. The most important factor related to 30 day survival in our CRE BSI cohort in children was empirical treatment that included at least one active antibiotic.
Giardiasis is highly prevalent in children and is often mildly symptomatic. First-line treatment is metronidazole, but treatment failure is not uncommon. We describe a paediatric series, to identify ...risk factors for treatment failure and to analyse the safety and effectiveness of other treatment strategies.
Retrospective observational study, including children diagnosed with giardiasis from 2014 to 2019. Diagnosis was based on direct visualisation by microscopy after concentration using an alcohol-based fixative, antigen detection and/or DNA detection by polymerase chain reaction in stool. Treatment failure was considered when GI was detected 4 weeks after treatment.
A total of 120 patients were included, 71.6% internationally adopted, median age 4.2 (2.3–7.3) years. Only 50% presented with symptoms, mainly diarrhoea (35%) and abdominal pain (14.1%); co-parasitism was frequent (45%). First-line treatment failure after a standard dose of metronidazole was 20%, lowering to 8.3% when a higher dose was administered (p < 0.001). Quinacrine was administered in 10 patients, with 100% effectiveness. Children <2 years were at higher risk of treatment failure (OR 3.49; 95% CI 1.06–11.53; p = 0.040).
In children with giardiasis, treatment failure is frequent, especially before 2 years of age. Quinacrine can be considered as a second-line treatment. After treatment, eradication should be confirmed.
Tuberculosis (TB) is the leading opportunistic infection in children with human immunodeficiency virus (HIV), but is uncommon in low prevalence regions. We aim to describe the changing epidemiology ...and clinical presentation of TB-HIV co-infection in a cohort of HIV-infected children in Spain.
Children diagnosed with TB between 1995 and 2016 in the paediatric HIV cohort were identified. The incidence and clinical presentation were compared in three periods: 1995-1999 (P1, before initiation of combined antiretroviral therapy, cART), 2000-2009 (P2, increase in immigration), and 2010-2016 (P3, decrease in immigration).
We included 29 TB cases among 1183 children aged <18 years (2.4%, 243/100 000 person-years). The proportion was stable in P1 and P2 (1.3%), but decreased in P3 (0.8%). The median age at TB diagnosis was 6.4 years (IQR 4-10.6); most children in P3 were aged >10 years (20% vs. 23.1% vs. 83.3%,
= 0.01). TB was diagnosed at HIV presentation in 11/29 children (37.9%). Foreign-born children accounted for respectively 0%, 8% and 67% of the total number of children in each period (
≤ 0.0001). One third had extrapulmonary TB; four children died (13.8%).
In our cohort, the incidence of TB-HIV co-infection decreased with decline in immigration. In regions with adequate cART coverage and low TB transmission, paediatric TB-HIV coinfection is uncommon, but associated with significant morbidity. Strategies for TB surveillance, diagnosis and treatment in this vulnerable population should be reinforced.
Objectives. Congenital cytomegalovirus infection (cCMV) has been considered more prevalent among HIV-exposed children during pregnancy. Spanish national guidelines recommend the cCMV screening in ...these newborns. Nowadays, pregnant women have a better control of HIV infection compared to previous decades. We aim to analyze the prevalence and associated risk factors to cCMV in these children. Patients and methods. A retrospective cross-sectorial study was performed. All newborns exposed to HIV were assisted in a third-level hospital (2014-2020). Epidemiological and clinical data of the mother and newborn were recorded. Shell vial urine culture and/or CRP were performed along the two first weeks of life for the neonatal screening of cCMV. Results. Overall 69 newborns were enrolled. A high proportion (82.4%) of the mothers had been diagnosed with HIV before getting pregnant. All women received ART during the pregnancy. Median T-CD4 lymphocytes before delivery was 641/mm3 (IQR: 480-865) and the viral load was undetectable in 83.6%. Serological test for CMV along the first trimester of pregnancy was performed in 73.5% (positive IgG in 96%). There were no congenital cases of HIV neither cCMV (CI 95%:0-5.3%). Conclusions. The cCMV prevalence in newborns exposed to HIV was 0%, lower than reported before, probably related to a better and earlier ART during pregnancy, leading to a better immunological status.
We conducted a multicenter clinical validity study of the Panbio coronavirus disease 2019 Antigen Rapid Test of nasopharyngeal samples in pediatric patients with coronavirus disease 2019–compatible ...symptoms of ≤5 days of evolution. Our study showed limited accuracy in nasopharyngeal antigen testing: overall sensitivity was 45.4%, and 99.8% of specificity, positive-predictive value was 92.5%.
