Assessing index CD4 and associated outcomes at 1-year in a tertiary HIV clinic, KwaZulu-Natal.

BACKGROUND:  Human immunodeficiency virus (HIV) management guidelines have evolved from initiating therapy at CD4 counts of ≤ 200 cells/m3 to implementing universal test and treat (UTT). This study aimed to assess whether in clinical practice, patients are presenting with higher baseline CD4 counts, describe the incidence of opportunistic infections and the proportion that achieved viral suppression. METHODS:  A retrospective cohort design with convenience sampling was conducted. Cohort 1 included patients initiated on antiretroviral therapy (ART) between 01 January 2014 and 31 December 2014, when criteria were set at CD4 count ≤ 350 cells/mm3. Cohort 2 included patients initiated on ART between 01 January 2019 and 31 December 2019, during the UTT era. RESULTS:  At ART initiation, the median CD4 cell was 170 cells/mm3 (interquartile range [IQR]: 85.5-287) in Cohort 1 cells/mm3 and 243 cells/mm3 (IQR: 120-411) in Cohort 2. Tuberculosis was the predominant OI in the group with CD4 cell count ≤ 200 cells/m3 in both Cohort 1 (26.8%) and Cohort 2 (27.9%), p = 0.039. At 1 year, virological suppression was achieved in only 77.7% and 84.7% of Cohorts 1 and 2 patients. CONCLUSION:  A notable portion of patients at King Edward VIII Hospital's HIV clinic commenced ART with CD4 counts significantly below the recommended guideline thresholds.Contribution: The research revealed a delay in initiating ART. A comprehensive reevaluation is essential to pinpoint the factors contributing to this delay and to devise customised interventions.

Diagnostic outcomes of bone marrow aspirate and trephine biopsies performed at a hospital in KwaZulu-Natal, South Africa.

BACKGROUND: Bone marrow aspiration and trephine biopsy (BMAT) are widely performed in adults to evaluate haematological and malignant conditions. However, the diagnostic yield from the procedure in unselected patients in the South African public sector has not previously been described. OBJECTIVES: We identified the main indications and most common diagnoses encountered for BMAT and described the demographic and blood profiles of patients, including HIV-positive patients, who had undergone the procedure at a tertiary hospital in KwaZulu-Natal. METHODS: We retrospectively reviewed laboratory data from January 2016 to December 2016 for all patients aged ≥ 13 years who underwent the procedure and stratified findings by demographic data. RESULTS: Among 120 BMAT biopsies studied, 80 (67%) cases were performed to evaluate suspected malignancy and a further 40 (33%) cases for non-malignant indications. The main indications for bone marrow examination were: cytopenias 38 (32%), lymphoma 35 (29%), leukaemia 21 (18%), and multiple myeloma 17 (14%). BMAT results revealed that 60 cases (50%) were malignant in origin, 30 cases (25%) were non-malignant and 30 cases (25%) were classified as normal. The common diagnoses were: leukaemia, 24 (20%); multiple myeloma, 16 (13%) and lymphoma, 13 (11%). Cases aged ≥ 50 years were more likely to have a malignant diagnosis (odds ratio: 5.8 (95% confidence interval: 2.2-17.1) p-value < 0.001). CONCLUSION: The diagnostic yield of BMAT was high, with significant abnormalities detected in three quarters of cases. Haematological malignancy was the more common diagnosis. Increasing age was associated with an increase in reporting of haematology malignancy.
