ABSTRACT Use of highly active antiretroviral therapy (HAART) has been linked to dyslipidemia and increased risk of cardiovascular disease (CVD) in HIV-infected patients in industrialized countries. The effects of HAART on lipid metabolism among sub-Saharan Africans, for whom access to antiretroviral therapy is expanding, remain largely unknown.
From July 2003 to May 2004, 987 antiretroviral-naive patients with symptomatic HIV disease or a CD4 count <250 cells/mm3 were started on HAART in the Home-Based AIDS Care (HBAC) Program in Tororo, Uganda. The HBAC Program provided weekly drug delivery and field-based clinical monitoring. Nonfasting repository sera from a subset of 374 patients were analyzed for levels of total cholesterol (TC), direct low-density lipoprotein cholesterol (LDL-c), direct high-density lipoprotein cholesterol (HDL-c), and triglycerides (TG) at baseline (before HAART) and after 12 and 24 months of HAART using Randox enzymatic kits (Crumlin, United Kingdom).
The 374 patients evaluated (49% women, mean age = 39 years, CD4 count = 124 cells/mm3, body mass index = 19.7 kg/m2) received initial HAART composed of stavudine, lamivudine, and either nevirapine (365 patients [98%]) or efavirenz (9 patients [2%]). During 24 months, 99 (26%) patients had single drug substitutions from stavudine to zidovudine and 27 (7%) had single drug substitutions from nevirapine to efavirenz. At baseline, the mean serum lipid concentrations were 120 mg/dL for TC, 53 mg/dL for LDL-c, 29 mg/dL for HDL-c, and 123 mg/dL for TG; values were generally comparable for men and women. During 24 months of treatment, TC increased by a mean of 31 mg/dL, LDL-c by a mean of 26 mg/dL, and HDL-c by a mean of 19 mg/dL, whereas the TC/HDL-c ratio decreased from a mean of 4.6 to 3.4 (all changes, P < 0.001). TG levels initially decreased and then returned to baseline levels by 24 months. At baseline and 24 months, respectively, TC was > or =200 mg/dL for 2% and 10% of patients, LDL-c was > or =130 mg/dL for 1% and 6%, HDL-c was <40 mg/dL for 88% and 41%, and TG were > or =150 mg/dL for 23% and 20%.
Rural Ugandans with advanced HIV disease initiating nevirapine- or efavirenz-based HAART experienced infrequent elevations in TC, LDL-c, and TG at baseline and after 24 months of therapy. Increases in HDL-c levels were substantial and proportionally greater than increases in TC or LDL-c levels. The risk of CVD and how it is affected by lipid changes in this rural African population are unknown. However, the changes we observed after 24 months of HAART seem unlikely to increase the risk of CVD.

- "There were 37,110 HIV-infected patients in total, with females representing approximately 28%. Thirty-one studies (61%) were conducted in low-and middleincome countries with the highest number of studies (n = 8) reported in India        , followed by six studies in Nigeria      , and four studies each in Brazil    , Norway    , and USA    . Nonetheless, studies conducted in high-income countries were generally larger in size (n = 30,120 participants), compared with studies conducted in low-and middleincome countries (n = 7488). "
ABSTRACT: Antiretroviral drugs increase biosynthesis and reduce hepatic clearance of serum cholesterol. It is thus important to evaluate the impact of antiretroviral treatment on serum lipoprotein levels and the risk of dyslipidemia. We searched EMBASE and PubMed for articles comparing lipid profiles between HIV-infected adult patients naïve and exposed to antiretroviral therapy (ART). Eligible studies were pooled by performing random-effects meta-analyses of mean serum lipoprotein levels and prevalence estimates of dyslipidemias. 51 observational studies comprising 37,110 patients were included in the meta-analyses. ART-exposed patients had significantly higher concentrations of total cholesterol (45 studies, mean difference [MD]=29.4mg/dL, 95% confidence interval [CI] 26.5 to 32.4, I(2)=82.2%), low density lipoprotein-cholesterol (37 studies, MD=14.9mg/dL, 95% CI 11.2 to 18.5, I(2)=86.1%), and triglycerides (43 studies, MD=46.8mg/dL, 95% CI 37.8 to 55.8, I(2)=97.1%), compared with ART-naïve patients. The risks of hypercholesterolemia (25 studies, pooled odds ratio [OR] 3.8, 95% CI 3.1 to 4.7, I(2)=60.0%) and hypertriglyceridemia (21 studies, OR 2.2, 95% CI 1.7 to 2.9, I(2)=81.7%) were also significantly higher among ART-exposed patients, compared with ART-naïve patients. Antiretroviral therapy is significantly associated with increase in serum lipid levels and increased risk of dyslipidemia. Whether or not these associations are causal should be investigated by future studies. Copyright © 2015 Elsevier Ireland Ltd.

- "Use of HAART has been linked to hyperglycemia, dyslipidemia and increased risk of cardiovascular disease (CVD) in HIV-infected patients in industrialized countries. The effects of HAART on glucose and lipid metabolism among sub-Saharan Africans, for whom access to antiretroviral therapy is expanding, remain largely unknown . This is specially a major gap that should be given high emphasis in a county like Ethiopia where increased use of HAART is higher since 2005. "
ABSTRACT: Background The effects of highly active antiretroviral therapy (HAART) on glucose and lipid metabolism among sub-Saharan Africans, for whom access to antiretroviral therapy is expanding, remain largely unknown. Therefore, the aim of this study was to assess antiretroviral treatment associated hyperglycemia and dyslipidemia among HIV infected patients at Burayu health center, Addis Ababa, Ethiopia. Methods A cross-sectional comparative study was conducted among HIV infected adults at Burayu Health Center, Addis Ababa, Ethiopia from September, 2011 to May, 2012. Equal number of HAART naïve and HAART initiated patients (n = 126 each) were included in the study. Demographic data were collected using a well-structured questionnaire. Total cholesterol (TC), Triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and glucose were determined. The data were analyzed using SPSS version 20 software. Result Of 252 study participants, 72.2% were females; mean age was 35.3 years; mean Body Mass Index (BMI) was 21.4(kg/m2); mean time living with the virus was 20.6 months and 15.5% were TB-HIV co-infected. The prevalence of hyperglycemia, increased LDL-C hypercholesterolemia, hypertriglyceridemia and decreased HDL-C were 7.9%, 23%, 42.1%, 46.8% and 50.8% in HAART and 5.6%, 7.1%, 11.1%, 31% and 73% in non-HAART groups, respectively. First line antiretrovirals were drugs containing 2 nucleoside backbones (from Zidovudine/Stavudine/Lamivudine/Tenofovir) with either Nevirapine or Efavirenz. There was statistically significant increase in serum lipid profile levels among HAART initiated patients than HAART naïve individuals (p =0.01 for TG and <0.001 for others). Conclusion First-line HAART is associated with potentially atherogenic lipid profile levels in patients with HIV infection compared to untreated patients. This indicates glucose and lipid profile levels need to be monitored regularly in HIV infected patients taking antiretroviral treatment.BMC Research Notes 06/2014; 7(1):380.

- "Fourth, our study had a short follow-up period of 90 days, a period during which underweight or emaciated patients may still be resetting their metabolic profiles following treatment. However, the few studies in resource poor settings that have followed patients for a longer period (up to 24 months) have reported similar associations . "
ABSTRACT: Background HIV and combination antiretroviral therapy (cART) may increase cardiovascular disease (CVD) risk. We assessed the early effects of cART on CVD risk markers in a population with presumed low CVD risk. Methods Adult patients (n=118) in Lusaka, Zambia were recruited at the time of initiation of cART for HIV/AIDS. Cardiometabolic risk factors were measured before and 90 days after starting cART. Participants were grouped according to cART regimens: Zidovudine + Lamivudine + Nevirapine (n=58); Stavudine + Lamivudine + Nevirapine (n=43); and ‘other’ (Zidovudine + Lamivudine + Efavirenz, Stavudine + Lamivudine + Efavirenz, Tenofovir + Emtricitabine + Efavirenz or Tenofovir + Emtricitabine + Nevirapine, n=17). ANOVA was used to test whether changes in cardiometabolic risk markers varied by cART regimen. Results From baseline to 90 days after initiation of cART, the prevalence of low levels of high-density lipoprotein cholesterol (<1.04 mmol/L for men and <1.30 mmol/L for women) significantly decreased (78.8% vs. 34.8%, P<0.001) while elevated total cholesterol (TC ≥5.18 mmol/L, 5.1% vs. 11.9%, P=0.03) and the homeostasis model assessment of insulin resistance ≥3.0 (1.7% vs. 17.0%, P<0.001) significantly increased. The prevalence of TC:HDL-c ratio ≥5.0 significantly decreased (44.9% vs. 6.8%, P<0.001). These changes in cardiometabolic risk markers were independent of the cART regimen. Conclusion Our results suggest that short-term cART is associated with a cardioprotective lipid profile in Zambia and a tendency towards insulin resistance regardless of the cART regimen.Lipids in Health and Disease 04/2013; 12(1):50.
