Abstract
Increasing demand for antiretroviral treatment (ART) together with a reduction in international funding during the last decade may jeopardize access to ART. Using data from a cross-sectional survey conducted in 2014 in 19 HIV services in the Centre and Littoral regions in Cameroon, we investigated the role of healthcare supply-related factors in time to ART initiation in HIV-positive patients eligible for ART at HIV diagnosis. HIV service profiles were built using cluster analysis. Factors associated with time to ART initiation were identified using a multilevel Cox model. The study population included 847 HIV-positive patients (women 72%, median age: 39 years). Median (interquartile range) time to ART initiation was 1.6 (0.5-4.3) months. Four HIV service profiles were identified: (1) small services with a limited staff practising partial task-shifting (n = 4); (2) experienced and well-equipped services practising task-shifting and involving HIV community-based organizations (n = 5); (3) small services with limited resources and activities (n = 6); (4) small services providing a large range of activities using task-shifting and involving HIV community-based organizations (n = 4). The multivariable model showed that HIV-positive patients over 39 years old [hazard ratio: 1.26 (95% confidence interval) (1.09-1.45), P = 0.002], those with disease symptoms [1.21 (1.04-1.41), P = 0.015] and those with hepatitis B co-infection [2.31 (1.15-4.66), P = 0.019] were all more likely to initiate ART early. However, patients in the first profile were less likely to initiate ART early [0.80 (0.65-0.99), P = 0.049] than those in the second profile, as were patients in the third profile [association only significant at the 10% level; 0.86 (0.72-1.02), P = 0.090]. Our findings provide a better understanding of the role played by healthcare supply-related factors in ART initiation. In HIV services with limited capacity, task-shifting and support from community-based organizations may improve treatment access. Additional funding is required to relieve healthcare supply-related barriers and achieve the goal of universal ART access.

Anti-Toxoplasmic Immunoglobulin G Quantitation Correlates with Immunovirological Parameters of HIV-Infected Cameroonians. Curr HIV Res 2021; 19:73-83. [PMID: 32885755 DOI: 10.2174/1570162x18666200903172523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Revised: 07/14/2020] [Accepted: 08/05/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Toxoplasmosis is still a neglected common opportunistic infection in immunocompromised individuals, who are mainly people living with HIV (PLHIV) in whom reactivation of toxoplasmosis may occur with advanced HIV conditions in resource-limited settings (RLS). OBJECTIVE The objective was to assess the correlation between anti-toxoplasmic immunoglobulin G (anti-Toxo IgG) concentration and the immuno-virological status of PLHIV. METHODS A cross-sectional study was conducted in the year 2018 among 100 PLHIV aged ≥18 years in Yaounde-Cameroon. For each participant, anti-Toxo IgG, CD4-T lymphocytes, and plasma viral load (PVL) were measured using ELISA, flow cytometry, and real-time PCR, respectively. RESULTS Overall, 56% of the participants were seropositive for anti-Toxo IgG, while 33% were negative and 11% were equivocal. All (n=19) those with PVL>1000 copies/mL were seropositive to anti-Toxo IgG versus 52.85% (37/70) with PVL<1000 copies/mL; p<0.0001. Interestingly, all (n=11) those with severe immunodeficiency (T-CD4<200 cells/μL) were positive to anti-Toxo IgG versus 57.69% (45/78) with T-CD4>200 cells/μL; p<0.0001. Most importantly, PVL and anti- Toxo IgG concentration were positively correlated (r = 0.54; p<0.0001), while T-CD4 and anti- Toxo IgG concentration were negatively correlated (r = - 0.70; p<0.0001). Adjusting age, gender, immune status, and virological profile in logistic regression shows that only immune status was independently associated with the serological status of toxoplasmosis (p=0.0004). CONCLUSION In Cameroon, about half of PLHIV might be seropositive to anti-Toxo IgG, with decreasing immunity appearing as a risk of toxoplasmosis relapse. Thus, in the context of immunodeficiency, routine quantification of anti-Toxo IgG would alleviate the programmatic burden of this opportunistic infection in RLS with the generalized HIV epidemic.

Abstract
OBJECTIVE Thrombocytopenia is an abnormal decrease in blood platelets, which can affect the prognosis of people living with HIV (PLHIV). In order to assess the burden of this haematological disorder, we evaluated the frequency of thrombocytopenia according to antiretroviral drug combinations, viremia and the immune status of PLHIV. RESULTS A cross-sectional and analytical study was conducted from June to November 2016 among 310 PLHIV at the "Chantal BIYA" International Reference Centre, Yaoundé, Cameroon. Overall rate of thrombocytopenia was 19.0% (59/310). The rate of thrombocytopenia was 64.6% (42/65) versus 6.9% (17/245) in ART-naïve versus ART-treated patients respectively, p < 0.0001. Following viral load, rate of thrombocytopenia was 15.8% (20/130) in those with undetectable viral load, and 34.1% (27/79) with viral loads > 3 log10 RNA/ml (p = 0.03). As concerns CD4-count, rate of thrombocytopenia was 16.2% (42/259) in those with ≥ 200 CD4/mm3 versus 33.3% (17/51) with < 200 CD4/mm3 (p = 0.0003). After adjusting for sex, ART, viral load and CD4, Viral load and ART exposure were significantly associated with decreased risk of thrombocytopenia (p < 0.05). Thrombocytopenia occurs especially among ART-naïve, high viremia and severe immune-compromised patients. Interestingly, ART coverage appears as an independent factor in preventing the occurrence of thrombocytopenia.
