| Abstract | |
Staphylococcus aureus nasal colonization and HIV infection represent public health problems of global concern. The overall objective was to identify the risk factors for nasal colonization by Staphylococcus aureus in people living with HIV / AIDS. Therefore, a case-control study was conducted, with people living with HIV / AIDS hospitalized at the units specialized in infectious disease care at a teaching hospital in the interior of São Paulo. Data were collected from January / 2013 to February / 2015 by means of an individual interview, including sociodemographic and clinical data, as well as the collection of nasal secretions with the aid of swab in Stuart\'s medium, both during the first 24 hours of hospitalization. The samples were sent and processed by the Laboratory of Microbiology of the institution itself. The inclusion criteria were: to be over 18 years of age, to be known as infected HIV, to be hospitalized. Statistical analyzes were performed using the Pearson chi-square test, Fisher\'s exact test, Student t-test, Wilcoxon test, and Univariate and Multivariate logistic regression using the SAS® software. The data are presented in tables and figures. The present study was approved by the Research Ethics Committee of the Ribeirão Preto College of Nursing (CAAE 38990114.5.0000.5393) and by the co- participating institution (CAAE 38990114.5.3001.5440). A total of 240 people living with HIV / AIDS participated in the study, of which 120 were Cases and 120 Controls; 65.0% of Cases and 55.0% of Controls were male: 35.8% of Cases were in the age group of 30 at 39 years and 45.8% of the Controls were aged from 40 to 49 years, the predominant ethnicity was white for Cases and Controls, 74.2% and 64.2%, respectively. The groups were homogeneous among themselves in relation to gender, ethnicity and schooling. The mean time of diagnosis was 9 years for Cases and 8.8 years for Controls. The final logistic regression model showed that the risk factors associated with Staphylococcus aureus nasal colonization in people living with HIV / AIDS were white, p = 0.05 (OR: 1.85, 95% CI: 1.00 - 3.57); having viral load> 40 copies / mL, p = 0.03 (OR: 2.90; IC95% 1.15 - 7.30); being with LT-CD4+ <200 cells / mm3 p = 0.001 (OR: 2.71; IC95% 1.53 - 4.81); and present opportunistic disease p = 0.014 (OR: 2,09; IC95% 1,20 - 3,67). In addition, it was also obtained by the final regression final model that the use of antiretroviral therapy is a protection factor of p = 0.008 (OR: 0.45; 95% CI 0.25 - 0.81) for nasal colonization by Staphylococcus aureus. We conclude that nasal colonization by Staphylococcus aureus in people living with HIV/AIDS was associated with factors: ethnicity, viral load, LT-CD4+ count, opportunistic infection, and antiretroviral use (AU) | |
