Focused assessment with sonography for HIV-associated tuberculosis (FASH) case series from a Rwandan district hospital.

INTRODUCTION

The majority of HIV-TB co-infection worldwide is reported in Africa. The risk of developing extra-pulmonary tuberculosis (EPTB) increases as immune deficiency progresses but is difficult to diagnose. Point-of-care ultrasonography (POCUS) can be an effective adjunct to identify and treat EPTB-associated findings using the focused assessment with sonography for HIV-associated TB (FASH) protocol.

CASE REPORT

Three HIV-infected patients without known history of EPTB presented to a Rwandan district hospital with fever and unclear infection. Initial testing did not reveal a source. Each patient was then evaluated with the FASH protocol by a Rwandan emergency physician with POCUS training. All patients had findings suggestive of EPTB by ultrasound. Anti-TB treatment was initiated, and all subsequently demonstrated symptom improvement.

DISCUSSION

This case series demonstrates the additional clinical information obtained. It describes how management was changed using POCUS and the FASH in a resource-limited setting in Rwanda and calls for further FASH protocol validation studies.
