Abstract Background The aim of this study was to establish the prevalence of lipodystrophy and its association to cumulative exposure to antiretroviral drugs. Method We conducted a cross sectional study in all HIV- infected patients attending the HIV clinic in the Centre hospitalier universitaire de Montréal (CHUM) with DEXA scan. Lipodystrophy was defined as a trunk/limb fat ratio ≥ 1.5. Association between cumulative exposure to antiretroviral (measured in years of use) with trunk/limb fat ratio (coded as a continuous variable) was assessed using univariate and multivariate linear regression for each antiretroviral drug with at least 40 exposed patients. Results One hundred sixty-six patients were included. Seventy-five percent were male, median age was 56 years, 67% were Caucasian. Overall, prevalence of lipodystrophy was 47%, with a mean trunk/limb fat ratio of 1.87, SD = 1.03, min = 0.6 and max = 5.87. Each 10-year increase in age and HIV infection duration was associated with an average increase of 0.24 and 0.34 for the trunk/limb fat ratio respectively. (p = 0.003, p = 0.002, respectively) Patients classified as lipodystrophic were more likely to be diabetic (50 vs. 28%, p = 0.07) and to have dyslipidemia (47 vs. 19%, p = 0.01). According to viral load at DEXA test, each one log increase was associated with less probability (0.7) of lipodystrophy. (p = 0.01) Among ARV drugs tested, there was an association between years of use of d4T, ritonavir and raltegravir and higher trunk/limb fat ratio (indicating more lipodystrophy) (p < 0.05). Conclusion Lipodystrophy is very common in HIV infected patients and is correlated with duration of some new antiretroviral drugs.

The increase in HIV infection and drug-resistant strains is an important public health concern, especially in resource-limited settings. However, the identification of factors related to the propagation of infectious diseases represents a crucial target offering an opportunity to reduce health care costs as well as deepening the focus on preventing infection in high-risk groups. In this study, we investigate the factors related to drug resistance among HIV-infected pregnant women in Luanda, the capital city of Angola. This was a part of a cross-sectional study conducted with 42 HIV-positive pregnant women. A blood sample was collected, and HIV-1 genotyping was carried out using an in-house method. Multivariate analyses were performed to determine the interaction between sociodemographic characteristics and drug resistance. HIV drug resistance was detected in 44.1% of the studied population. High probabilities of drug resistance were observed for HIV-infected pregnant women living in rural areas (AOR: 2.73; 95% CI: 0.50–14.9) with high educational level (AOR: 6.27; 95% CI: 0.77–51.2) and comorbidities (AOR: 5.47; 95% CI: 0.28–106) and infected with a HIV-1 non-B subtype other than subtype C (AOR: 1.60; 95% CI: 0.25–10.3). The present study reports high HIV drug resistance. Furthermore, older-age, rural areas, high educational levels, unemployed status, having comorbidities, and HIV-1 subtypes were factors related to drug resistance. These factors impact on drug susceptibility and need to be urgently addressed in order to promote health education campaigns able to prevent the spread of drug-resistant HIV strains in Angola.

Abstract Background: Toxoplasmosis remains a neglected common opportunistic infection in immunocompromised individuals, who are mainly people living with HIV (PLWHIV) in whom reactivation of toxoplasmosis may occur with advanced HIV conditions in resource-limited settings (RLS). Our objective was to evaluate the correlation between the anti-toxoplasmic IgG (Tg-IgG) concentration and the immuno-virological status of PLWHIV.Methods : A prospective and cross-sectional study was conducted among PLWHIV aged>18 years from February to November 2018 at the Chantal BIYA international Reference Centre. Blood samples were collected from eligible consenting PLWHIV; Tg-IgG level was assessed by quantitative ELISA, CD4-T lymphocytes counts were measured by flow cytometry and HIV-1 plasma viral load (PVL) measurement by real-time-PCR. Data were analysed using Excel and Graph Pad softwares; with p<0.05 considered statistically significant.Results : A total of 100 PLWHIV were enrolled: 56% seropositive for IgG anti- Toxoplasma gondii, 33% seronegative and 11% indeterminate results. According to viremia, 100% (19/19) of those with PVL>1000 copies/mL were seropositive to Tg-IgG versus 52.85% (37/70) of those with PVL<1000 copies/mL (median [IQR] IgG concentration 152.78 [139.24-444.43] versus 34.44 [13.04-36.47] IU/mL, respectively); p<0.0001. According to CD4, 100% (11/11) of those with T-CD4<200 cells/µL were seropositive to Tg-IgG versus 57.69% (45/78) of those with T-CD4>200 cells/µL (median IgG [IQR] 432.92 [145.06-450.47] versus 35.01 [15.01-38.01] IU/mL, respectively); p<0.0001. Interestingly, there were moderate-positive and strong-negative correlations respectively with HIV-1 PVL (r = 0.54; p<0.0001) and T-CD4 (r = -0.70; p<0.0001) as compared to Tg-IgG concentration. After adjusting for age, gender, immune status and PVL in logistic regression, only poor immune status (T-CD4<200 cells/µL) was independently associated to Tg-IgG seropositivity (p=0.0004).Conclusion : In a typical RLS like Cameroon, about half of PLWHIV might be seropositive to Tg-IgG. Of relevance, decreasing immunity appears with risk of increasing IgG anti- T gondii concentration, which suggests a relapse of toxoplasmosis. Thus, in the context of immunodeficiency, routine quantification of Tg-IgG would alleviate the programmatic burden of this opportunistic infection in RLS with generalized HIV epidemics.
