A Breakthrough in the Challenges of Tuberculosis Diagnosis: Lateral Flow Urine Lipoarabinomannan (LAM) Assay for the Diagnosis of Active Tuberculosis in a Subset of Human Immuno Deficiency Virus (HIV) Patients at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia.

Background: Tuberculosis is commonly detected late or not at all in HIV-positive people. Rapid and sensitive molecular tests like Gene X-pert have recently become available to replace or supplement existing conventional tests for detecting tuberculosis, and the World Health Organization (WHO) recommends that these rapid techniques be used as the initial diagnostic test for tuberculosis to avoid delays in starting appropriate treatment. The lipoarabinomannan was approved by the national ministry of health in August 2021 for the detection of active tuberculosis in specified groups. Case Summary: It is not uncommon for tuberculosis to be difficult to diagnose in this population, and we believe that our experiences with urine lipoarabinomannan for the detection of active tuberculosis will benefit other clinicians and, ultimately, patients. We discussed the experiences of two human immunodeficiency virus (HIV) patients with putative active tuberculosis, whose tuberculosis workups were negative by conventional methods, including gene expert but found to be positive by urine lipoarabinomannan and who were started on anti-tuberculosis medicines and improved. They are now in a good condition and are taking their medications regularly without any problems. Conclusion: Ending the suffering of HIV patients necessitates lobbying for more accurate tuberculosis diagnosis. The urine Lipoarabinomannan (LAM) assay will address the shortcomings of traditional sputum-based diagnostic tests including sputum Acid Fast Bacilli (AFB) and Gene X-pert, making it a credible alternative for diagnosing tuberculosis in people with HIV. The results of this case series demonstrated that TB LAM is a milestone for the difficulties in TB diagnosis in HIV patients. As of now, the national guideline only suggests urine LAM for HIV patients who fulfill the set criteria. We recommend the stakeholders to increase the availability, and extrapolate the recommendation to other populations including non-HIV patients.
