Clinical Trial Summary

A cross-sectional study on acute undifferentiated fever and the utility of biomarkers in differentiating bacterial from viral infection among acute febrile patients in Gondar, northwest Ethiopia.

Description:

General objective: To assess the causes of acute undifferentiated febrile illness and evaluation of biomarkers for differentiation of bacterial and viral infections among outpatients at University of Gondar (UOG) Hospital, Northwest Ethiopia Specific objectives 1. To determine the number of malaria cases, bacterial infections (by blood culture and polymearase chain reaction (PCR) for Rickettsia and Borrelia), and arboviral infections (DENV, YFV, CHIKV) among all acute febrile patients 2. To evaluate the diagnostic performance different assays (RDT, RT-(reverse transcriptase)PCR, ELISA) for the diagnosis of DENV 3. To evaluate the qualitative detection of C-reactive protein (CRP) and Myxovirus resistance protein (MxA) (by FebriDx RDT) and quantitative CRP detection for differentiating bacterial and viral infections Study design, population, materials and methods: a cross-sectional cohort study on febrile patients presenting with acute fever at the emergency ward of the UOG hospital from June to August 2019. Clinical and epidemiological data will be recorded in a pseudo-anonymized and collected using an electronic data collection tool (KoBoToolbox). Blood will be collected for RDT testing, blood culture, PCR and serum for ELISA and RT-PCR. Sample size: 200 acute febrile patients Expected results and relevance: Evaluation of the causes of acute febrile illness and the role of biomarkers in differentiating viral and bacterial infections will increase the awareness of circulating pathogens and improve patient management. This evidence will contribute to a more rational use of laboratory diagnostic tests, antibiotics and antimalarial treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The differentiation of bacterial infections and viral infections among acute febrile patients with biomarkers	CRP (bacterial biomarker) and MxA (viral biomarker) will be evaluated for differentiating confirmed bacterial and viral infections.	within 7 days after onset of fever
Secondary	The number of malaria cases, bacterial infections, viral infections and unknown etiologies among acute febrile patients in Gondar	Different diagnostic tools will be used for analysis of acute febrile patient samples to confirm malaria (by RDT), bacterial infection (by blood culture and PCR for Rickettsia and Borrelia) and for viral infections (by RT-PCR for DENV, CHIKV, YFV). Samples negative for all these tests are defined as unknown etiology.	within 7 days after onset of fever
Secondary	The comparison of different assays for diagnosis of DENV	Different diagnostic tests will be evaluated for the detection of acute DENV infection (NS1 RDT, RT-PCR, ELISA IgM) and past DENV infection (ELISA IgG) among acute febrile patients.	within 7 days after onset of fever
Secondary	The comparison of the qualitative and qualitative detection of CRP for differentiating bacterial and viral infections	Qualitative CRP levels will be measured by FebriDx test and quantitative CRP levels will be measured by QuikReadGo. The detection of > 20mg/L CRP will be used to evaluate the confirmed bacterial infections and to compare with antibiotic treatment.	within 7 days after onset of fever
