Characteristics of Tuberculous Meningitis in HIV-Positive Patients from Northeast Romania.

BACKGROUND AND OBJECTIVES: One of the most severe forms of extrapulmonary tuberculosis (EPTB) is tuberculous meningitis (TBM), which is linked to significant morbidity and high mortality. It is well recognized that human immunodeficiency virus (HIV)-positive people are more likely to develop EPTB, including TBM, especially if they have severe immunodeficiencies. We aim to highlight the profile and the characteristics of TBM in HIV-infected patients. MATERIAL AND METHODS: We conducted a retrospective clinical study based on hospital medical records of patients diagnosed with HIV/AIDS (acquired immunodeficiency syndrome) and TBM in Northeast Romania, hospitalized at "St. Parascheva" Clinical Hospital of Infectious Diseases of Iasi from 1 January 2010 to 1 December 2022. RESULTS: From a total number of 1692 patients on record in our center, 195 had a HIV-tuberculosis (TB) coinfection, and 19 cases were HIV-TBM coinfected. Six cases were newly HIV-diagnosed late presenters, and thirteen patients' names were already found in the center's records with deficient immunological viral status (median CD4 lymphocyte level 47/mm3). The average age in the study group was 27 years old. The clinical manifestations and cerebrospinal fluid (CSF) variables were typical in most cases, despite the severe immunodepression of the patients. The Thwaites scoring system correctly identified 89.5% of the patients. The median admission period was 18 days; the lethality rate was 31.6%, despite access to ART and anti-TB drugs, and was associated with a more severe immunosuppression. No rifampicin resistance was detected. CONCLUSIONS: TBM appeared in a minority of our HIV cohort and affected severely immunodepressed patients; the clinical and CSF variables had a typical aspect in most cases, and the Thwaites scoring system performed well for this type of patient. The lethality rate was high and was correlated with a more severe immunodepression.

Treatment initiation or switch to BIC/FTC/TAF - real-world safety and efficacy data from two HIV centers in Romania.

INTRODUCTION: Development of highly active antiretroviral therapy marked an important step forward in the management of people living with HIV and fixed dose combinations are now available to be used as modern antiretroviral regimens. The single-tablet regimen bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) was recently approved in Europe and included in international guidelines and recommendations. It became available in Romania in early 2021. We present the real-world results from a retrospective analysis of patients initiating BIC/FTC/TAF in two HIV centers in Romania. METHODS: This retrospective analysis included patients treated with BIC/FTC/TAF (first-line or switch) in two HIV centers in Romania, one in Bucharest and one in Iași. We collected data on baseline patient characteristics, reasons for initiation of BIC/FTC/TAF and preliminary clinical and laboratory efficacy, safety and tolerability data. All assessments had been performed according to local practice. Statistical analyses were mostly descriptive and association analysis was performed to assess changes in laboratory parameters from baseline to data cut-off (October 2021). RESULTS: In total, 122 patients were initiated on BIC/FTC/TAF in routine clinical practice from February to October 2021 in the two HIV centers, either as first-line or switch. The majority of patients were male (71%). The median age at baseline was 35.0 years (IQR 32.0-50.8 years). Overall, 91 patients (75%) were treatment-experienced and the most frequent reason for switch was treatment simplification (79%). The mean ± standard deviation follow-up duration on treatment with BIC/FTC/TAF was 101.6 ± 64.2 days until the cut-off date for this analysis. We found no significant changes in lipid values, blood glucose or liver enzymes, coupled with a significant decrease in viral load (p=0.001). A low number of adverse events occurred during the treatment period (n=4): two cases of fatigue and two gastrointestinal reactions. No patient discontinued BIC/FTC/TAF and the overall tolerability was good. CONCLUSIONS: The insights of the first report on BIC/FTC/TAF use in routine clinical practice in Romania provide an overview of effectiveness and safety to local clinicians treating this patient population.
