The importance of oral microflora composition in HIV-infected patients is well recognized. However, no studies so far have dealt with age-related changes in periodontal pathogens occurrence in HIV+ individuals. The aim of the present study was to assess and compare temporal changes of bacteria frequency in younger (≥35 years) and older (≥50 years) HIV-infected and non-infected individuals. Bacterial DNA was isolated from buccal swabs of 30 younger and 30 older subjects in both HIV+ and HIV-groups. By means of PCR the following microorganisms were detected: Aggregatibacter actinomycetemcomitans, Eikenella corrodens, Peptostreptococcus micros, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola. Oral and periodontal examinations were performed in all subjects. The prevalence of microorganisms was significantly higher in HIV+ patients compared to controls, and their distribution showed a notable shift. The decreasing incidence in HIV-subjects was: Pi

We performed a study to identify factors related to favorable response to highly active-antiretroviral therapy (HAART) in HIV-infected women. A retrospective study was performed on 216 women who had initiated HAART from January 1, 1998 to December 31, 2012, at the HIV/AIDS Center, Belgrade, Serbia. Participants were followed-up for 8.2 ± 3.4 years. The mean age was 37 ± 9.7 years. During follow-up, it was found that 26 patients had died. Clinical AIDS at initiation of HAART was observed in 43.9% patients, while 64.8% had a CD4+ T-cell count below 200 cells/μL. Multivariate analyses revealed that the single factor independently related to a favorable response to HAART was good compliance (odds [OR] ratio for survival = 2.9, 95% confidence intervals [CI] = 1.0-8.6, p = 0.03), while a baseline CD4+ T-cell count below 100 cells/μL, hepatitis C virus coinfection, and aged 40 years and older were all associated with an unfavorable response to HAART (OR = 0.28, 95% CI = 0.15-0.52, p < 0.001; OR = 0.49, 95% CI = 0.22-0.8, p = 0.008; OR = 0.41, 95% CI = 0.21-0.79, p = 0.008, respectively). The estimated 14-year-survival was 100% in patients with sustained viral suppression, regardless of the CD4+ counts achieved (p = 0.6, log-rank). If women with advanced HIV-related immunodeficiency reach and maintain optimal viral suppression during HAART, regardless of the level of immune recovery, and if they continue to maintain this suppression for up to a mean 8 years of treatment, their prognosis may be fairly good, even in resource-limited settings. © 2014 Copyright Taylor and Francis Group, LLC.

Background: Data about correlation of interleukins (IL-1 α IL-1 β IFN γ IL-2, IL-4, IL-6, IL-8, IL-10), adipocytokines (leptin, adiponectin, monocyte chemoattractant protein-1 (MCP-1), resistin, plasminogen activator inhibitor-1 (PAI-1), tumor necrosis factor alpha (TNFα), ferritin, C reactive protein (CRP) and vascular endothelial growth factor (VEGF) with homeostasis model assessment (HOMA) in HIV/AIDS patients are still limited. Therefore the aim of this study was to evaluate the possible correlations of serum levels of PAI-1, leptin and ferritin with HOMA in HIV/AIDS patients treated with combined antiretroviral therapy (cART). Methods: This cross-sectional study included 64 HIV/AIDS patients, all Caucasians, receiving cART at the HIV/AIDS Centre, Belgrade, Serbia. PAI-1, leptin, ferritin and insulin levels were measured using the Metabolic Syndrome Array I (Randox Laboratories Ltd., London, UK), while adiponectin and resistin levels were measured using Metabolic Syndrome Array II (Randox Laboratories Ltd., London, UK), interleukins (IL-1 α IL-1 β IFN γ IL-2, IL-4, IL-6, IL-8, IL-10), MCP-1, TNF-α as well as VEGF was measured using Cytokine Array I (Randox Laboratories Ltd., London, UK). Insulin resistance was determined using the homeostasis model assessment index (HOMA). Multicollinearity of independent variables in multivariate model was analyzed using Variance Inflation Factor. Results: Correlation analysis revealed significant correlations between HOMA and waist circumference, body mass index, patients’ age, number of cART combinations and triglycerides (p = 0.001, p = 0.001, p = 0.050, p = 0.044, p = 0.002, respectively). HOMA negatively correlated with levels of high density lipoprotein (HDL) (Rho = −0.282; p = 0.025). PAI-1 (Rho = 0.334; p= 0.007) and leptin (Rho = 0.492; p = 0.001) together with ferritin (Rho = 0.396, p = 0.001) positively and significantly correlated with HOMA. Levels of IL-1 α IL-1 β IFN γ IL-2, IL-4, IL-6, IL-8, IL-10, adiponectin, MCP-1, resistin, TNF-α CRP and VEGF did not significantly correlate with HOMA. Further, multiple logistic regression showed that there is a statistically significant correlation between PAI, leptin and ferritin with HOMA levels (p = 0.042; p < 0.001, p = 0.009). Conclusions: We showed significant correlation between PAI-1, leptin and ferritin, independently of each other with HOMA, in HIV/AIDS patients on cART. © 2018 Elsevier Inc.

Previous molecular studies of Serbian HIV epidemic identified the dominance of subtype B and presence of clusters related HIV-1 transmission, in particular among men who have sex with men (MSM). In order to get a deeper understanding of the complexities of HIV sub-epidemics in Serbia, epidemic trends, temporal origin and phylodynamic characteristics in general population and subpopulations were analyzed by means of mathematical modeling, phylogenetic analysis and latent class analysis (LCA). Fitting of the logistic curve of trends for a cumulative annual number of new HIV cases in 1984–2016, in general population and MSM transmission group, was performed. Both datasets fitted the logistic growth model, showing the early exponential phase of the growth curve. According to the suggested model, in the year 2030, the number of newly diagnosed HIV cases in Serbia will continue to grow, in particular in the MSM transmission group. Further, a detailed phylogenetic analysis was performed on 385 sequences from the period 1997–2015. Identification of transmission clusters, estimation of population growth (Ne), of the effective reproductive number (Re) and time of the most recent common ancestor (tMRCA) were estimated employing Bayesian and maximum likelihood methods. A substantial proportion of 53% of subtype B sequences was found within transmission clusters/network. Phylodynamic analysis revealed Re over one during the whole period investigated, with the steepest slopes and a recent tMRCA for MSM transmission group subtype B clades, in line with a growing trend in the number of transmissions in years approaching the end of the study period. Contrary, heterosexual clades in both studied subtypes – B and C – showed modest growth and stagnation. LCA analysis identified five latent classes, with transmission clusters dominantly present in 2/5 classes, linked to MSM transmission living in the capital city and with the high prevalence of co-infection with HBV and/or other STIs. Presented findings imply that HIV epidemic in Serbia is still in the exponential growth phase, in particular, related to the MSM transmission, with estimated steep growth curve until 2030. The obtained results imply that an average new HIV patient in Serbia is a young man with concomitant sexually transmitted infection.

A prospective study to evaluate the incidence of herpes zoster (HZ) as an immune restoration disease in patients with AIDS during highly active antiretroviral therapy (HAART) was conducted in a series of 115 patients diagnosed with AIDS initiated on HAART between 1 January 2000 and 31 July 2001. Of these, a single dermatomal HZ episode occurred in 14 (12%) patients within one and 15 months of HAART (median eight months). The HZ patients were similar to the non-HZ patients in age, sex, and HIV transmission risk factor, but had a more advanced disease. Compared with the baseline values, the viral loads significantly (P < 0.01) decreased, while the mean CD4+ T-cell counts increased by almost four-fold (P < 0.01) in both groups at the time of the HZ episode (or equivalent in non-HZ), but remained below 400/mL in the HZ patients. HZ during HAART is an immunopathological consequence of the improvement of the host immune response, correlating with the beginning of immune restoration.

We appraised the relationship between the biological and the chronological age and estimated the rate of biological aging in HIV-infected patients. Two independent biomarkers, the relative telomere length and iron metabolism parameters, were analyzed in younger (,35) and older (.50) HIV-infected and uninfected patients (control group). In our control group, telomeres of younger patients were significantly longer than telomeres of older ones. However, in HIV-infected participants, the difference in the length of telomeres was lost. By combining the length of telomeres with serum iron, ferritin, and transferrin iron-binding capacity, a new formula for determination of the aging process was developed. The life expectancy of the healthy population was related to their biological age, and HIV-infected patients were biologically older. The effect of antiretroviral HIV drug therapies varied with respect to the biological aging process. IMPORTANCE This article is focused on the dynamics of human aging. Moreover, its interdisciplinary approach is applicable to various systems that are aging. Copyright © 2023 Toljić et al.

Aims: Lopinavir (LPV) is not a first-line regimen. According to recent WHO data, LPV usage in low- and middle-income countries accounted for approximately 52% of the adult and 23% of the paediatric protease inhibitor market in 2017. Since LPV is a substrate for the SLCO1B1 (OATP1B1) transporter, the aim of this study was to assess the impact of SLCO1B1 polymorphisms (rs11045819, rs4149032 and rs4149056) on LPV trough plasma concentrations (Ctrough) in Serbian patients. Methods: Plasma samples from 104 HIV/AIDS Caucasians were collected. LPV Ctrough was quantified using liquid-chromatography-mass spectrometry. Genotyping was carried out using real-time-PCR-based allelic discrimination. One-way analysis of variance, t test and linear regression were used for data analysis. Results: The overall mean (SD) LPV Ctrough was 5885 ± 2755 ng/mL. Significant differences were between patients with different rs11045819 genotypes: CC (LPV median Ctrough = 6072 ng/mL, interquartile range (IQR) = 4318–7617 ng/mL), CA (LPV median Ctrough = 4987 ng/mL, IQR = 4300–6295 ng/mL) and AA (LPV median Ctrough = 3648 ng/mL, IQR = 1949–4072 ng/mL) (P =.005). Significant differences were also observed according to rs4149032 genotype: CC (LPV median Ctrough = 6027 ng/mL, IQR =4548–8250 ng/mL), CT (LPV median Ctrough = 5553 ng/mL, IQR = 4300–6888 ng/mL) and TT (LPV median Ctrough = 4408 ng/mL, IQR = 3361–5233 ng/mL) (P =.007). For rs4149056 a statistically significant difference between T-homozygotes (LPV median Ctrough = 5434 ng/mL, IQR = 3855–6830 ng/mL), heterozygotes (LPV median Ctrough = 6707 ng/mL, IQR = 5088–8063 ng/mL) and C-homozygotes (LPV median Ctrough = 13906 ng/mL, IQR = 12946–14866 ng/mL) was observed (P =.002). In multivariate regression analysis, only the SLCO1B1 rs4149056 polymorphism was independently associated with higher LPV Ctrough (β = 2834.5 [1442–4226.9] ng/mL [P =.001]). Conclusions: Our results demonstrate a statistically significant influence of the SLCO1B1 rs4149056 polymorphism on higher LPV Ctrough in Caucasian HIV/AIDS patients. © 2020 The British Pharmacological Society

Background The role of interleukins in the pathogenesis of lipodystrophy in HIV/AIDS-patients is still not understood. The aim of this study was to evaluate the relationship between serum levels of interleukins between HIV/AIDS-patients with or without lipodystrophy, as well as between different subgroups of lipodystrophy (lipoatrophy, lipohypertrophy, mixed-fat-redistribution) and patients without lipodystrophy. Methods Cross-sectional study of 66 HIV/AIDS patients, all Caucasians. Serum levels of interleukins (IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10) were measured using Cytokine-Array-1 on Evidence Investigator, Biochip Array Technology. The associations between interleukins and anthropometric and metabolic variables were estimated by Spearman-correlation. Analysis of covariance with bootstrapping method (ACBM) was used to examine relationship between interleukins and lipodystrophy categories adjusted for confounding variables. Results The lipodystrophy was observed in 29 (44%) patients, while 15 (52%) had lipoatrophy, 4 (14%) lipohypertrophy and 10 (34%) patients had mixed fat redistribution. There were 37 (56%) patients without lipodystrophy. Significantly lower levels of IL-4 and IL-10 were observed in lipodystrophy vs. non-lipodystrophy (p = 0.008; p = 0.027, respectively). No differences were found relating IL-1α, IL-1β, IL-2, IL-6 and IL-8 levels in lipodystrophy vs. non-lipodystrophy. In patient subgroup with lipoatrophy, significantly lower levels of IL-4 and IL-10 were found when compared to non-lipodystrophy (p = 0.043; p = 0.031, respectively). In lipohypertrophy subgroup significantly lower levels of IL-4 were found when compared to non-lipodystrophy (p = 0.003). In order to estimate the correlation of IL-4 and IL-10 and the presence of lipodystrophy, ACBM showed that correlation of IL-4 levels in patients with lipodystrophy remains statistically significant (p = 0.004) in all types of lipodystrophy: lipoatrophy, lipohypertrophy and mix-fat-redistribution (p = 0.027; p = 0.009; p = 0.017, respectively) after adjustment for age, BMI. Conclusions IL-4 and IL-10 levels were significantly lower in lipodystrophy vs. non-lipodystrophy. According to our knowledge, we showed for the first time significant correlation between IL-4 levels and lipodystrophy development in HIV/AIDS patients. © 2017

In recent years mathematical modeling has become a valuable tool in the analysis of infectious disease dynamics at both individual and population level. Mathematical models allow us to extrapolate from current information about the natural history of a disease, therapy/intervention outcome, state and progress of an outbreak, to predict the future and, most importantly, to quantify the uncertainty in these predictions, thus, increasingly gaining the ability to perform as a link between basic science, clinical medicine and public health. © GERMS 2012.
