Treatment of HIV infection is a lifelong process and associated with chronic diseases. We evaluated the prevalence and predictors of metabolic syndrome (MetS) and cardiovascular diseases (CVDs) with individual antiretroviral drugs exposure among HIV-infected men in Taiwan. A total of 200 patients’ data were collected with a mean age of 32.9. Among them, those who had CD4 positive cell number less than 350/mL were eligible to have highly active antiretroviral therapy (HAART). Patients were divided into group-1 that contains 45 treatment-naïve participants, and group-2 that includes 155 HAART treatment-experienced participants. MetS prevalence between group-1 and group-2 was 18% and 31%, respectively. The Framingham Risk Score (FRS) for the naïve and experienced groups were 4.7 ± 4.2 and 3.87 ± 5.92, respectively. High triglyceride (TG > 150 mg/dL) in group-1 and group-2 were 15.6% and 36.6% (p < 0.05), whereas, lower high-density lipoprotein (HDL < 39 mg/dL) in group-1 and group-2 presented as 76.7% versus 51% (p < 0.05), respectively. In group-2, treatment with protease inhibitors (PIs) resulted in higher TG levels when compared with non-nucleotide reverse transcriptase inhibitors (NNRTIs) and integrase inhibitors (InSTIs). The prevalence of MetS in the treatment-naïve group was lower than that of the treatment-experienced group; high TG level resulted in higher MetS prevalence in the treatment-experienced group. In contrast, the cardiovascular risk of FRS in the treatment-naïve group was higher than that of the treatment-experienced group, which may result from the low HDL level. Although group-1 participants have a higher risk of developing CVDs, in group-2, an increasing TG level in PIs user indicated higher CVDs risk. TG and HDL are two significant biofactors that required regular evaluation in HIV-positive individuals.

Abstract Background:Although HIV-related deaths have decreased dramatically following the introduction of antiretroviral therapy (ART), HIV infection itself causes increased morbidity and mortality for both non-AIDS-related events or chronic inflammation and immune activation. The use of certain antiretroviral drugs can contribute to this process. Methods:We investigated 26 potential biomarkers in serum samples from HIV-1 infected patients virologically suppressed under ART. The mailobjective of our study was to evaluate if virological suppression achieved with a triple drug regimen containing tenofovir disoproxil fumarate co-formulated with emtricitabine (TDF/FTC) as backbone, could correlate with a better immunological and inflammatory profile in relation to the third class of antiretroviral drug administered. The eligible patients were then divided into 3 groups in relation to the third drug associated with TDF/FTC : NNRTI (Group 1, n=18), + PI (Group 2, n=18) and INI (Group 3, n=18). Results: Traditionally, inflammatory cytokines and chemokines were more represented in Group 2 than in Group 3 (IL-1Ra, p=0.013; IL-12p70 p=0.039; TNF-α p=0.041; IL-8, p=0.027; MIP1 β, p=0.033). Eotaxin showed lower levels in Group 1 compared to Group 2 (p=0.010), while IP-10 was significantly lower in Group 1 compared to both Group 2 and Group 3 (p=0.003 and p=0.007, respectively).Conclusions: our results seem to discourage the administration of PI as a third drug in a virologically effective antiretroviral regimen, as its use is linked to the detection of higher levels of pro-inflammatory mediators than INI and NNRTI.

Inflammatory Status

In HIV infected patients an increased incidence of cardiac events has been reported since the introduction of highly active antiretroviral therapy (HAART). Antiretroviral drugs’ regimens are, in fact, associated with several metabolic side effects, such as dyslipidemia, impaired glucose metabolism and abnormal body fat distribution, that increase cardiovascular risk of HIV subjects. In addition, HIV infection itself, the chronic inflammatory status and the frequent presence in this population of traditional risk factors contribute to an higher incidence of cardio and cerebrovascular events. In last years several studies showed the occurrence of carotid vascular impairment in patients treated with protease inhibitors (PI). Similarly the DAD Study reported an increase of 26% of the risk of myocardial infarction in patients on HAART and that this risk was independently associated with longer exposure to PI, after multivariate adjustments. A correct evaluation of the metabolic status before starting HAART and an adequate control of drugs-related metabolic abnormalities may reduce the incidence of cardiac events and still improve HIV patients prognosis. This review will focus on the metabolic effects of antiretroviral drugs and on the contribution of combination antiretroviral therapy on cardiovascular risk.

Aim. To study the effect of hyperglycemia on the total surface charge of the erythrocyte membrane (SCEM) in patients with metabolic syndrome (MS).Material and methods. 112 MS patients were examined (45 men and 67 women) (mean age 61.4±7.2 years, average MS duration 8.7±5.2 years). The level of SCEM was determined by adsorption of a positive cationic dye (cationic blue O) on the surface of the plasma membrane of erythrocytes to completely neutralize their negative charge, followed by photometry of the solution and calculation of the number of charges on the cell surface of erythrocytes.Results. In the main group of patients with MS, abdominal obesity was observed in 100% of patients, arterial hypertension – in 73%, hyperglycemia – in 75%, dyslipidemia – in 80%. The level of glycated hemoglobin (HbA1c) was determined in all patients with MS, which was 7.3±1.9%. Patients with MS were conditionally divided according to the level of HbA1c into 2 groups (group 1 – HbA1c from 6.6 to 7.8%, group 2 – more than 7.8%). In MS patients with hyperglycemia, the SCEM values were significantly lower than in the group of patients without hyperglycemia (1.58±0.05×107 and 1.64±0.03×107, respectively; p=0.001)., Significant negative correlations between SCEM and the fasting blood glucose level, hyperglycemia duration, HbA1c level were found in patients with MS.Conclusion. SCEM indices reliably depended on the presence, severity and duration of hyperglycemia, which indicated the effect of impaired carbohydrate metabolism on the state of electric charge of erythrocyte membranes and, therefore, on the mechanisms of microvascular blood flow, thereby contributing to the development of vascular changes in patients with MS.

ABSTRACT Initiation of highly active antiretroviral therapy (HAART) for HIV-infected individuals is associated with control of viremia, improved CD4 counts, and declining systemic HIV-specific immune responses. While HAART effectively reduces plasma viremia, it remains unclear how effectively antiretroviral drugs reach mucosal surfaces, such as those of the genital tract. The aim of this study was to determine the effect of HAART on genital tract CD4 T cell reconstitution, HIV shedding, and HIV-specific T cell responses. Cervical cytobrush and blood specimens were obtained from 35 HIV-infected, HAART-naïve women and 27 women on HAART in order to investigate HIV Gag-specific T cell responses by intracellular gamma interferon (IFN-γ) staining. Interleukin 1β (IL-1β), IL-6, and IL-8 concentrations were measured by enzyme-linked immunosorbent assays (ELISA). We show that for HIV-infected women, HAART is associated with significantly improved CD4 T cell counts both in blood and at the cervix. While HAART effectively suppressed both blood and cervical viremia, HIV-specific CD8 T cell responses in blood were lost, while those at the cervix were preserved.

Abstract Background: Poor compliance to highly active antiretroviral therapy (HAART) can result in the poor quality of life in children living with HIV/AIDS because of low plasma drug concentration and the possibility of drug resistance. This study evaluates the response of caregivers for determination of adherence and the four quality of life domains in children (aged 14 years and under) on HAART.Methods: We conducted a cross-sectional study of 188 children, each accompanied by their caregivers at Ola During Children's Hospital and Makeni Government Hospital between September and November 2016. Adherence to HAART and Quality of life was assessed using the WHO Quality of life summary questionnaire (WHOQOL-BREF). We obtained ethical approval from the Sierra Leone Ethics and Scientific Review Committee. Results: The study revealed 5.9% adherence amongst paediatric patients, and a strong association of adherent patients(p=0.019*) to the physical health domain (mean=64.61 SD=8.1).Caregiver HIV status showed a strong association with the physical (mean=58.3, SD=11.7 and p=0.024*), and psychological health domains (mean=68.2, SD=14.7 and p=0.001). Caregiver type (mother/father/sibling) accompanying child to hospital also showed strong associated with the physical (mean=58.0, SD=10.6, p <0.001), psychological (mean 68.2 SD=14.81 p <0.001) and environmental health domains (mean=59.7, SD=13.47, p <0.001). Further regression analysis showed a strong association with physical health domain for HIV positive caregivers (p=0.014) and adherent paediatric patients (p=0.005). Nuclear family also showed a strong association with psychological (p<0.001) and environmental (p=0.001) health domains. Conclusion: This study showed a strong association between the quality of life domains and the involvement of nuclear family caregiver, HIV-positive caregiver and adherence to HAART. Our study suggests that the involvement of any member of the nuclear family, HIV positive parents and patient adherence to therapy can improve the quality of life of paediatric HIV/AIDS patients on highly active antiretroviral therapy in the two hospitals.
