Between May 1983 and September 1991 eleven patients with severe haemophilia underwent splenectomy for HIV-related thrombocytopenia. The sustained complete remission rate (platelets > 100 x 10(9)/l) was 82% over a mean follow-up period of 54 months. The group was compared with 22 age-matched non-thrombocytopenic HIV seropositive haemophiliacs who had not undergone splenectomy. Both groups had equivalent use of factor concentrate and there was no significant difference between the groups in terms of anti-retroviral treatment. Analysis of clinical progression of HIV infection and CD4 positive lymphocyte (CD4+) counts, for the time since splenectomy, revealed no significant difference in progression of HIV infection in the splenectomized group compared with the control group. It is concluded that splenectomy is an effective treatment for HIV-related thrombocytopenia and has no adverse effect on the progression of HIV infection.

Background: Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB), remains a global health crisis, especially in sub-Saharan Africa, where high human immune virus (HIV) prevalence exacerbates the problem. The co-infection of TB and HIV creates a deadly combination, increasing susceptibility and complicating disease progression and treatment. Ethiopia, classified as a high-burden country, faces significant challenges despite efforts to reduce co-infection rates.

Early antiretroviral therapy (ART) initiation is known to limit the establishment of the HIV reservoir, with studies suggesting benefits such as a reduced number of infected cells and a smaller latent reservoir. However, the long-term impact of early ART initiation on the dynamics of the infected cell pool remains unclear, and clinical evidence directly comparing proviral integration site counts between early and late ART initiation is limited. In this study, we used Linear Target Amplification-PCR (LTA-PCR) and Next Generation Sequencing to compare unique integration site (UIS) clonal counts between individuals who initiated ART during acute HIV infection stage (Acute-ART group) and those in the AIDS stage (AIDS-ART group).

Background: HIV continues to disproportionately impact men who have sex with men (MSM) in the United States (US). Pre-exposure prophylaxis (PrEP) is effective, but disparities persist. Limited studies have conducted systematic evaluations of social determinants of health (SDOH) and their effects on PrEP persistence among MSM.

Background: Older people living with HIV-1 (PLWH) experience a dual burden from the combined effects of aging and HIV-1 infection, resulting in significant immune dysfunction. Despite receiving HAART, immune reconstitution is not fully optimized. The objective of this study was to investigate the impact of aging and HAART on T cell subsets and function in PLWH across different age groups, thereby providing novel insights into the prognosis of older PLWH.

Background: Despite advancements in Human Immunodeficiency Virus (HIV) treatment and care, undernutrition remains a significant concern, accelerating disease progression and risk of Acquired Immune Deficiency Syndrome (AIDS)-related deaths. The nutritional status of second-line antiretroviral treatment (SLART) users in Ethiopia has not been thoroughly investigated. So, this study aimed to assess the nutritional status of HIV/AIDS patients who were on SLART and its associated factors in Northern Ethiopia.
