Human immunodeficiency virus (HIV) is associated with altered metabolism and increased energy expenditure, this energy requirement increases significantly as the HIV disease progresses. This study aimed on the use of Adenosine triphosphate (ATP), Guanosine triphosphate (GTP), Adenosine diphosphate (ADP) and Adenosine monophosphate (AMP) as an index of energy utilization, storage and energy balance in HIV infected individuals. This is a longitudinal, prospective, case-controlled study involving seventy seven (77) HIV Sero-positive individuals newly diagnosed attending retroviral disease treatment centre of Nnamdi Azikiwe University University Teaching Hospital (NAUTH) aged 18-60 years both male and female not on highly active antiretroviral therapy (HAART), were enrolled in the study as test subjects and thirty six (36) apparently healthy HIV Sero-negative individuals both male and female as control subjects. ATP, GTP, ADP and AMP were estimated by enzyme linked immunosorbent assay (ELISA), while, total Energy Balance was determined by calculation. The data obtained were subjected to statistical analysis using SPSS software application (version 21.0) and the results expressed as mean ± standard deviation. The plasma ATP and GTP were significantly lower (P<0.05) in both HIV pre-treatment and post-treatment group compared with control group. Meanwhile, the plasma level of ADP and AMP were significantly lower (P<0.05) in HIV post-treatment group compared with HIV pre-treatment and control group. There was also a significant difference (P<0.05) in ATP, ADP, AMP and GTP level between HIV pre-treatment and post-treatment group. Meanwhile, the energy balance was lower (P<0.05) in HIV groups compared with control group. However, the energy balance in HIV post-treatment group was significantly lower (P<0.05) compared to HIV pre- treatment group. In conclusion, the significant changes in the biochemical parameters measured suggest altered metabolism, increased energy expenditure and energy deficit/negative energy balance in HIV subjects resulting from increased energy expenditure. Hence, High energy molecules such ATP, ADP, GTP and AMP can be used to predict early energy deficit and manage energy imbalance in HIV infected individuals.
This was a cross-sectional study aimed to evaluate the use of albumin, hepatic lipase (HL) and lipoprotein lipase (LPL) enzyme as predictive markers of treatment failure in HIV-1 infected individuals. 154 participants {40 (group A), 35 (group B) on antiretroviral drugs (Test group) and 79 (group C) HIV naive participants (Control group)} aged 18 and 65 years were randomly recruited. Blood sample was collected from each test participant 6 months apart and once from control for determination of Albumin, HL, LPL, viral load (VL), CD4+ cells count. VL was significantly decreased while, Albumin, HL and LPL activities were significantly higher in test participants when compared with control P ≤ 0.05 respectively). Biochemical markers in test participants at 6 months of therapy were significantly lower compared with 12 months of therapy (P ≤ 0.05). Albumin and VL correlated positively with CD4 count while, lamivudine, nevirapine, tenofovir, HL, LPL correlated strongly and negatively with VL (P < 0.05 respectively). The high sensitivities and positive predictive value of albumin showed their predictive superiority over CD4+ count, HL, LPL and antiretroviral drug concentrations.The study thus, concludes that hypoalbuminemia with decreased HL and LPL activities were associated with unsuppressed viral load above 1000 copies/ml. This suggests that albumin; HL and LPL are good biochemical markers for prediction of treatment failure or success in participants on antiretroviral drugs.
Background: There is limited information on if HIV infection induces stress in pregnancy. HIV can possibly contribute to the alterations in some fetal viability hormones thereby lead to adverse pregnancy outcome. The present study aimed to assess the possible changes in maternal cortisol, Adrenocorticotropic (ACTH), Pregnancy associated plasma protein-A (PAPP-A) and alpha-fetoprotein (AFP) hormone concentrations in HIV-infected pregnant women and their pregnancy outcomes. Methods:A cross sectional study of 80 (Eighty) volunteer pregnant women aged (18-49) years recruited during routine antenatal clinics in Nnamdi Azikiwe Teaching Hospital, Nnewi, Anambra State, Nigeria was conducted. The participants were divided into groups: 40 (forty) apparently healthy pregnant and 40 (forty) HIV-infected pregnant women. 5 ml of morning blood samples were collected from each subject in their 1 st and 2 nd trimesters for estimation of Cortisol, ACTH, AFP and PAPP-A using ELISA method. Results:The result showed that the mean systolic and diastolic blood pressures (mmHg) of HIV pregnant women were significantly higher than control (p<0.05 respectively). The mean value of cortisol (ng/ml) in HIV pregnant women was significantly higher when compared with control subjects (p<0.05). Cortisol showed inverse significant correlation with AFP in HIV-infected pregnant women. Maternal outcomes showed thatt HIV-infected pregnant women had significantly higher incidence of miscarriages and preeclampsia with higher incidence of perinatal outcomes such as low birth weight babies (LBW), preterm delivery, spontaneous abortion, still birth and low Apgar scores when compared with apparently normal pregnant women (P<0.05 respectively).Conclusion: the significantly higher cortisol level and BP in HIV pregnant women is indicative of oxidative stress due to perceived stress by HIV infection which might predispose the affected women to hypertension and preeclampsia. The highest adverse reactions observed in HIV pregnant women might be related to the damaged immune system by HIV infection however, the placental defect associated with increased placental permeability to AFP and the activity of the insulin-like growth factor (IGF) system is not related to the activity of stress thereby do not influence their birth outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
