Enteroviral meningitis in infants and children commonly leads to hospital admission. Diagnosing viral meningitis can be difficult clinically. We examined the usefulness of enteroviral polymerase chain reaction (PCR) testing using cerebrospinal fluid (CSF) samples on clinical practice by comparing positive enteroviral CSF PCR cases (n = 39/136) to negative controls using both clinical outcomes and laboratory parameters. A positive result correlated with a reduced admission to high dependency unit, reduced the duration of antibiotics and a shorter length of stay (P < .05). Adjusted CSF white cell count > 5/μL correlated with positive PCR (P < .05) but would have missed 32% of cases of enteroviral meningitis. Following these findings, an algorithm for the management of suspected viral meningitis has been introduced.
Juvenile systemic lupus erythematosus (JSLE) is characterised by onset before 18 years of age and more severe disease phenotype, increased morbidity and mortality compared to adult-onset SLE. Management strategies in JSLE rely heavily on evidence derived from adult-onset SLE studies; therefore, identifying biomarkers associated with the disease pathogenesis and reflecting particularities of JSLE clinical phenotype holds promise for better patient management and improved outcomes. This narrative review summarises the evidence related to various traditional and novel biomarkers that have shown a promising role in identifying and predicting specific organ involvement in JSLE and appraises the evidence regarding their clinical utility, focusing in particular on renal biomarkers, while also emphasising the research into cardiovascular, haematological, neurological, skin and joint disease-related JSLE biomarkers, as well as genetic biomarkers with potential clinical applications.
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.
