Background Children seem relatively protected from serious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) related disease, but little is known about children living in settings with high tuberculosis and HIV burden. This study reflects clinical data on South African children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods We collected clinical data of children aged younger than 13 years with laboratory confirmed SARS-CoV-2 presenting to Tygerberg Hospital, Cape Town between 17th of April and 24th of July 2020. Results Hundred and fifty-nine children (median age 48·0 months (interquartile range, IQR 12·0-106·0)) were included. Hospitalized children (n=62), median age of 13·5 months (IQR 1·8-43·5) were younger than children not admitted (n=97), median age 81·0 months (IQR 34·5-120·5, p< 0·01). Thirty-three of 159 (20·8%) children had pre-existing medical conditions. Fifty-one of 62 (82·3%) hospitalized children were symptomatic; lower respiratory tract infection was diagnosed in 21/51 (41·2%) and 11/16 (68·8%) children younger than 3 months of age. Respiratory support was required in 25/51 (49·0%) children; 13/25 (52·0%) children were younger than 3 months. One child was HIV infected and 11/51 (21·2%) were HIV exposed uninfected and 7/51 (13·7%) children had a recent or new diagnosis of tuberculosis. Conclusion Children less than 1 year of age hospitalized with SARS-CoV-2 in Cape Town frequently required respiratory support, the access to oxygen may be limited in some LMICs which could potentially drive morbidity and mortality. HIV infection was uncommon but a relationship between HIV exposure, tuberculosis and SARS-CoV-2 should be explored.
To evaluate the performance of the Pediatric Index of Mortality 3 as mortality risk assessment model. DESIGN:This prospective study included all admissions 30 days to 18 years old for 12 months during 2016 and 2017. Data gathered included the following: age and gender, diagnosis and reason for PICU admission, data specific for the Pediatric Index of Mortality 3 calculation, PICU outcomes (death or survival), and length of PICU stay.SETTING: Nine units that care for children within tertiary or quaternary academic hospitals in South Africa. PATIENTS:All admissions 30 days to 18 years old, excluding premature infants, children who died within 2 hours of admission, or children transferred to other PICUs, and those older than 18 years old. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS:There were 3,681 admissions of which 2,253 (61.3%) were male. The median age was 18 months (interquartile range, 6-59.5 mo). There were 354 deaths (9.6%). The Pediatric Index of Mortality 3 predicted 277.47 deaths (7.5%). The overall standardized mortality ratio was 1.28. The area under the receiver operating characteristic curve was 0.81 (95% CI 0.79-0.83). The Hosmer-Lemeshow goodness-of-fit test statistic was 174.4 (p < 0.001). Standardized mortality ratio for all age groups was greater than 1. Standardized mortality ratio for diagnostic subgroups was mostly greater than 1 except for those whose reason for PICU admission was classified as accident, toxin and envenomation, and metabolic which had an standardized mortality ratio less than 1. There were similar proportions of respiratory patients, but significantly greater proportions of neurologic and cardiac (including postoperative) patients in the Pediatric Index of Mortality 3 derivation cohort than the South African cohort. In contrast, the South African cohort contained a significantly greater proportion of miscellaneous (including injury/accident victims) and postoperative noncardiac patients. CONCLUSIONS:The Pediatric Index of Mortality 3 discrimination between death and survival among South African units was good. Case-mix differences between these units and the Pediatric Index of Mortality 3 derivation cohort may partly explain the poor calibration. We need to recalibrate Pediatric Index of Mortality 3 to the local setting.
A 9-year-old girl from black ethnic origin presented with a history of fever, cough, loss of weight and right-sided chest wall pain for 2 weeks. Chest X-ray demonstrated an effusion, which was shown to be loculated on chest CT scan. She was not responding to medical treatment and at thoracotomy loculated pus was drained. (TB) was cultured from the pus. TB is a rare cause of loculated empyema with an overlapping clinical and radiological picture with pyogenic infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
