Oral lesions in HIV positive AIDS adolescents perinatally infected undergoing HAART
2010
Objective: To assess the prevalence of the oral lesions related to HIV-infection (HIV-OL) in HIV+/AIDS adolescents (=13 years old), and the differences with HIV+/AIDS children (=3 - 0.05). Oral candidiasis was the most prevalent oral lesion in both groups. Association (p <0.05) of a high prevalence of HIV-OL and oral candidiasis with a high viral load was observed in both study groups. Conclusions: Adolescents perinatally HIV-infected have a high prevalence of HIV-OL. Oral candidiasis still is the most frequent oral opportunistic infection. Oral lesions could have association to viral failure in HIV+/AIDS adolescents undergoing HAART
Determinants of HIV outpatient service utilization according to HIV parameters
2014
Introduction : The increased life expectancy of HIV patients in the era of highly active antiretroviral therapy has had profound consequences for the healthcare systems that provide their care. It is useful to assess whether healthcare resources need to be adapted to the different stages of HIV infection or to patient characteristics [1]. To study how patient features influence utilization of out patient services, we retrospectively analyzed the electronic health record of HIV-positive patients who had followed day-care programs at the AIDS Center of the University of Palermo, Italy. Materials and Methods : 223 HIV-infected subjects were recruited and divided into two groups according to CD…
270 Increased hospital mortality in HIV-infected patients with acute coronary or cerebrovascular syndromes. Analysis from a French nationwide hospita…
2011
Background After more than two decades of the AIDS epidemic, the spectrum of HIV-associated vascular diseases has considerably evolved from infectious disease with improved survival, to premature atherosclerosis. As a consequence, acute atherosclerosis complications, such as acute coronary and cerebrovascular syndromes (ACS and CVS) are currently growing. However, only few data are available on HIV-infected patients in the setting of ACS/CVS. The aim of the present study was to determine the prevalence of HIV, as well as the characteristics and hospital case fatality of HIV-infected patients with CVS and ACS. Methods From the French nationwide hospital medical information database, data fro…
Factors Associated with Nonsuppression of HIV Infection in the Spanish VACH Cohort.
2020
We aim to determine the prevalence of HIV nonsuppression and factors associated with it. This is a cross-sectional multicenter study carried out in January 2016 with data of the VACH Cohort, a registry participated by 23 hospitals from most regions of Spain. The prevalence of HIV nonsuppression, defined as HIV RNA ≥200 copies/mL, is documented. The possible association of HIV nonsuppression with sociodemographic and clinical variables is assessed with a logistic regression analysis. A total of 30,843 adult patients are included; 7,358 of them (23.86%) have nonsuppressed HIV. An association is found between nonsuppression of HIV and the following variables: lower body mass index, lower age o…

Recent advances on HIV DNA vaccines development: Stepwise improvements to clinical trials.
2019
According to WHO (World Health Organization) reports, more than 770,000 people died from HIV and almost 1.7 million people becoming newly infected in the worldwide in 2018. Therefore, many attempts should be done to produce a forceful vaccine to control the AIDS. DNA-based vaccines have been investigated for HIV vaccination by researches during the recent 20 years. The DNA vaccines are novel approach for induction of both type of immune responses (cellular and humoral) in the host cells and have many advantages including high stability, fast and easy of fabrication and absence of severe side effects when compared with other vaccination methods. Recent studies have been focused on vaccine de…
Monocyte to lymphocyte blood ratio in tuberculosis and HIV patients: Comparative analysis, preliminary data
2017
Recent data confirmed the hypothesis suggested by historical studies that the ratio of peripheral blood monocytes to lymphocytes (M/L) is associated with the risk of tuberculosis (TB) disease. We retrospectively analyzed the electronic health records of tuberculosis and HIV-positive patients who had followed day-care programs at the AIDS Center of the University of Palermo, Italy. 261 patients were recruited and divided into 6 groups as follows: healthy control group (HCG: 47 pts), latent HIV negative infected TB group (LIG, 43 pts), active HIV negative tuberculosis (TAG: 61 pts), treated tuberculosis HIV negative (TTG: 44 pts), HIV drug-naive patients tested TST and QFT-IT-negative with ne…
A density functional study of flavonoid compounds with anti-HIV activity.
2005
Abstract Quantum chemical calculations at the DFT/B3LYP theory level, with the 6-31G* basis set, was employed to calculate a set of molecular properties of 26 flavonoid compounds with anti-HIV activity. The correlation between biological activity and structural properties was obtained by using the multiple linear regression method. The model obtained showed not only statistical significance but also predictive ability. We demonstrate in this paper that the anti-HIV activity of compounds can be related with the molecular hydrophobicity (ClogP), the electronegativity ( χ ) and the charges on some key atoms, while that the toxicity can be related with the electronic affinities (EA), ClogP and …
Osteoporosis risk factors in HIV positive women with osteoporosis: A retrospective analysis
2017
Multifactorial risk factors such as HIV/HCV co-infection and antiretroviral therapy (ARV) have been associated with osteoporosis in HIV+ women. We retrospectively analysed which known risk factors were associated with the diagnosis of osteoporosis, according to the WHO definition, in HIV positive women who were followed-up at the AIDS Centre of the University of Palermo, Italy between January 2011 and December 2014. Twenty-one HIV+ women with osteoporosis (13 HIV+ mono-infected and 8 HIV/HCV co-infected females) who underwent dual-energy X-ray absorptiometry (DXA) and liver stiffness assessment were included in the study. No significant differences between the HIV and HIV/HCV group were fou…
Effects of triterpenes on the immune system.
2010
Ethnopharmacological relevance: Triterpenes, which comprise a broad chemical group of active principles, are implicated in the mechanisms of action and pharmacological effects of many medicinal plants used in folk medicine against diseases in which the immune system is implicated. They have been described as anti-inflammatory, antiviral, antimicrobial, and antitumoral agents, as well as being immunomodulator compounds. Several of them are implicated in the resolution of immune diseases, although their effects have not always been clearly correlated. Aim of the review: The aim of this review is to compile relevant data on the mechanisms of action of triterpenes isolated from active ethnomedi…
