Abstract

BACKGROUND: 

HIV infected patients, especially those treated with antiretroviral (ARV) drugs, show an increased risk and incidence of cardiovascular disease.

OBJECTIVES: 

The aim of this study was to evaluate the progression of subclinical atherosclerosis in the carotid arteries, expressed as the value of carotid intima-media thickness (cIMT) and the amount of atherosclerotic plaques, and to analyze the correlation between cIMT and risk factors for cardiovascular diseases in a cohort of HIV infected patients.

METHODS: 

The analysis included 72 HIV infected patients, mean age 39.4 years, and 27 healthy HIV negative individuals, matched for age and sex. The data collected included evaluation of the infection, ARV treatment, past cardiovascular events, assessment of traditional and nontraditional risk factors for cardiovascular diseases, cIMT measurements and amount of atherosclerotic plaques in the carotid arteries.

RESULTS: 

HIV infected patients show more advanced subclinical atherosclerosis in the carotid arteries (cIMT and plaques incidence). The cardiovascular risk profile of the HIV infected patients is significantly different from HIV negative people. Among the HIV positive group lower body mass index (BMI) and higher waist/hip ratio (WHR) are observed. The concentration of all cholesterol fractions is lower, whereas the concentration of triglycerides is higher. Cigarette smoking is more common among HIV-infected individuals. A strong statistical correlation between cIMT and age, hypertension, non-high-density lipoprotein (non-HDL) cholesterol and ARV time were found. Total and LDL cholesterol, and lifetime smoking exposure also affect the cIMT. The relationship between cIMT and current HIV RNA may indicate the impact of the current infection status on the cIMT dynamics in this subpopulation.

Project assumptions

The overall goal of the project is to develop an innovative multifactor mathematical model enabling monitoring of bath contamination used in the electropolishing process of austenitic stainless steels. This model will allow optimization and reduction of process costs and will have an impact on reducing environmental pollution during electrolytic polishing of austenitic stainless steels.

The final outcome of the project will consist in the development of a method of monitoring the gradual contamination of the electropolishing bath.

Team

The team deals with research in the field of electrochemistry, wastewater treatment, monitoring and optimization of processes in laboratory and industrial conditions. The diverse experience of individual members of the IonsMonit team is its strength.
