Abstrakt: Background: Managing Lassa fever (LF) patients is challenging because of the complexity of this life-threatening infectious disease, the necessary isolation measures, and the limited resources in countries where it is endemic. Point-of-care ultrasonography (POCUS) is a promising low-cost imaging technique that may help in guiding the management of patients.
Methods: We conducted this observational study at the Irrua Specialist Teaching Hospital in Nigeria. We developed a POCUS protocol, trained local physicians who applied the protocol to LF patients and recorded and interpreted the clips. These were then independently re-evaluated by an external expert, and associations with clinical, laboratory and virological data were analyzed.
Findings: We developed the POCUS protocol based on existing literature and expert opinion and trained two clinicians, who then used POCUS to examine 46 patients. We observed at least one pathological finding in 29 (63%) patients. Ascites was found in 14 (30%), pericardial effusion in 10 (22%), pleural effusion in 5 (11%), and polyserositis in 7 (15%) patients, respectively. Eight patients (17%) showed hyperechoic kidneys. Seven patients succumbed to the disease while 39 patients survived, resulting in a fatality rate of 15%. Pleural effusions and hyper-echoic kidneys were associated with increased mortality.
Interpretation: In acute LF, a newly established POCUS protocol readily identified a high prevalence of clinically relevant pathological findings. The assessment by POCUS required minimal resources and training; the detected pathologies such as pleural effusions and kidney injury may help to guide the clinical management of the most at-risk LF patients.
