Clinical Trial Summary
The objective of this study is to identify clinically informative biomarkers of host defense
pathways with potential utility as diagnostic and prognostic tools among children
hospitalized with acute febrile illness in a resource-constrained sub-Saharan African
setting.
The working hypothesis is that a panel of biomarkers, readily measurable from a peripheral
blood sample, may serve as a clinically useful instrument to distinguish between common
pediatric causes of fever, predict those children at greatest need of aggressive supportive
care and/or adjunctive therapies, and identify those children at greatest risk of mortality.
The use of objective and quantitative tools may facilitate the triage and clinical care of
febrile children admitted to hospital in the sub-Saharan African context.
Description:
For pediatric patients presenting to Jinja Regional Referral Hospital in whom admission to
hospital is deemed necessary by an attending physician, the parent or guardian will be
approached for consent to participate in the study. If granted, a small volume (1mL) of blood
will be withdrawn for processing and storage. A RDT for malaria and whole blood lactate level
will be performed at the bedside. Basic demographic and clinical data will be collected from
the case admission record, and patients will be followed during their hospital admission.
Possible outcomes will include: death, discharge without disability, discharge with
disability, abscondment, and loss to follow-up. The length of stay among survivors will be
recorded (excluding patients leaving against medical advice).
Serum samples will be shipped to the collaborating laboratory in Canada for analysis for
biomarkers. ELISA-based commercially-available assays for biomarker levels will be used to
quantify biomarker levels. In order to measure levels of 13 biomarkers from a plasma sample
of 500uL or less, highly co-ordinated procedures with experienced technicians are required to
perform the ELISA. Our laboratory in Canada has established protocols, experienced staff able
to perform the testing, as well as equipment and reagents allowing the testing to be done
efficiently. While it would be desirable to augment Ugandan capacity for biomarker testing,
this would require significant investment of time and resources for training and testing, and
may not be feasible in the context of this early study. If biomarkers can be identified that
have clinical utility, laboratory capacity for ELISA measurement of levels should be
developed or a simplified platform (e.g., lateral flow immunochromatographic test) should be
developed.
Pneumonia and meningitis will be diagnosed clinically. A combination of tachypnea,
respiratory distress (nasal flaring, intercostal and/or subcostal indrawing, or cyanosis) and
characteristic findings on chest auscultation (asymmetrical air entry, crackles, dullness to
percussion) will be used to make a clinical diagnosis of pneumonia. In our setting, chest
x-ray is not available on site and radiographic confirmation will not be routinely available.
Neck stiffness, positive Kernig's or Brudzinsky's signs, convulsions and coma will be used to
make a diagnosis of meningitis. Where a lumbar puncture is performed, according to clinical
judgment, the results will be used to complement clinical diagnosis. CSF pleiocytosis or a
positive CSF culture for recognized pathogens will be used to support the diagnosis of
meningitis.
