CHINCHA L, Omayra et al. Parasite intestinal infection and factors associated with coccidian infection in adults at public hospital in Lima, Peru. Rev. chil. infectol. [online]. 2009, vol.26, n.5, pp. 440-444. ISSN 0716-1018. doi: 10.4067/S0716-10182009000600008.
Objective: To evalúate the frequency of intestinal parasites and risk factors associated with coccidian infection in patients cared for at a public hospital in Lima-Peru. Methods: A descriptive, cross-sectional study was conducted using reports of the parasitology laboratory. Patients included were >18 years, who gave at least one faecal sample for parasitologic evaluation. Logistic regression was used to calcúlate Odd Ratios (OR) and 95%) confidence intervals. Results: 2.056 patients were included in the analysis, 55.2%> of them were males and 334 (16.3%) were HlVpositive. Overall, Blostocystis hominis was the most frequent parasite (35.4%). The multivariate model adjusted for sex shows that HIV infection (OR = 4.53; 95%CI: 3.03-6.77), being hospitalized (OR = 2.42; 95%CI: 1.06-5.52), and age ≥ 40 years (OR = 0.57; 95%IC: 0.37-0.86) were associated with coccidian mfection. Conclusions: Blostocystis hominis was the most frequent parasite in HIV positive and negative patients. Being hospitalized and HIV infection were risk factors for coccidian infection, but age ≥ 40 years was a protective factor.
