Resistant Tuberculosis in HIV-Positive Patients: A Growing Public Health Threat

Abstract

<i>Introduction: </i>Tuberculosis (TB) is a pathology considered one of the main causes of death by single infectious agent, ranking just after HIV / AIDS. Indeed, its emergence and the difficulty of its treatment, especially in the resistant form, in patients with co-infection with other diseases immundéprimante as HIV.<i> Observation 1:</i> 31 years old presented with febrile headaches complicated by epileptic seizures. The MRI scan showed 3 cockeyed and multilocular lesions suggesting neuromeningeal tuberculosis. HIV serology came back positive and during the first line treatment he relapsed and the resistance test was positive.<i> Observation 2:</i> 45 progressive alteration of the state associated with signs of tuberculosis impregnation and a meningeal syndrome. BK in the CSF and in the sputum was positive and brain imaging allowed us to retain the diagnosis of a neuromeningeal tuberculosis. The patient was put on anti-bacillary ERIP k4 and a corticotherapy. The workup for co-infection was able to establish an HIV infection. After 3 weeks of anti-bacillary treatment, the patient had a bad evolution and the search for resistance came back positive. <i>Observation 3: </i>25 years old, pulmonary tuberculosis manifested by a hemoptysis of small abundance associated with a deep alteration of the general state, 3 BK positive sputum, as well as the image of a tuberculous cavern on the thoracic CT. Bad evolution after 2 months of treatment of first worsening of symptoms neuro and systemic involvement the search for resistance came back positive. <i>Discussion:</i> Drug-resistant tuberculosis is a major global public health challenge. In this article, we present three cases of drug-resistant TB in HIV-coinfected patients, highlighting the emergence and increasing prevalence of multidrug-resistant TB (MDR-TB) strains worldwide. In order to control the spread of this dreaded disease, it is essential to improve treatment regimens, promote vaccination, educate affected patients, and promote adherence to treatment. <i>conclusion: </i>Diagnosis of drug-resistant tuberculosis should be prompt and considered if there is a delay or lack of improvement with conventional tuberculosis treatment.
