About
This study aims to identify the aetiology of childhood meningitis in Southwestern Uganda and develop and evaluate new methods for point-of-care diagnosis of childhood meningitis in a low-income setting. A prospective observational study including 600 children aged 0-12 years will be conducted during 1 year in Mbarara, Uganda. We estimate to recruit about 300 children with suspected meningitis (cases), and 300 with non-severe infection age-matched as controls.
Full description
The current gold standard for laboratory diagnostics of suspected childhood meningitis are microbiology culture of CSF and polymerase chain reaction (PCR). However, these methods are expensive, time-consuming, require dedicated facilities and trained professionals, that are often lacking in low-income health systems. Our team has developed a new vertical flow paper printed microarray method for rapid, inexpensive and multiplexed microbiology analysis of cerebrospinal fluid (CSF), with potential for point-of-care use in low-income settings. This study will evaluate the diagnostic accuracy of this newly developed paper printed microarray method.
The bioMérieux FilmArray® ME Panel is an existing multiplexed PCR based system for rapid microbiology analyses of CSF. Even though previous studies have reported good diagnostic accuracy of the FilmArray® system, the studies have mostly been focused on evaluating the system in high-income settings.
This study will do a field evaluation of the diagnostic performance and clinical usability of the FilmArray® ME Panel in a low-income setting in Mbarara, Uganda.
A study by Page et al, conducted 2009-2012 in Mbarara, Uganda, identified the most frequent pathogen causing childhood bacterial meningitis to be Streptococcus pneumoniae. This is also the case on a global level, with the addition of the bacteria Neisseria meningitidis and Haemophilus influenzae type B. However, the Page study did not find a single case of Neisseria meningitidis, which is in contrast to most other reports from low-, middle- and high-income countries. Furthermore, after the finalisation of the Page study, pneumococcal conjugate vaccines were introduced to the Ugandan childhood immunisation program. This study will identify the current aetiology of childhood meningitis and the impact of the pneumococcal conjugate vaccine, in Mbarara, Uganda, and also study the carriage and characteristics of Neisseria meningitis in children in the area.
Myxovirus resistance protein A (MxA) blood levels have been reported to be elevated in children with respiratory tract infections of viral aetiology, as compared to bacterial aetiology. Previous studies have also shown a higher abundance of MxA in viral encephalitis, however this only through histological analyses of post-mortem brain tissue samples.
This study aims to investigate the correlation of blood MxA levels in children with viral, bacterial and malarial meningitis in Mbarara, Uganda by analysing the protein profile and temporal dynamic in blood of children with severe and non-severe infection.
