“…They were primarily adults between 35 and 49 years of age (mean age, 36.7 years), which was similar to the results from Irapuato, Mexico, where the highest prevalence was observed in the 31-40 year age group [20]. The HBsAg-positive group in the present study had a higher education level compared to the HCVpositive group (Table 1) and to other blood banks in the country [23].…”

“…A comparison to the results from previous studies in the general populations and blood donors from Mexico and Veracruz revealed that the HBsAg prevalence in Veracruz blood donors (0.11%) was lower than that found by a national health survey of the general population (0.21%) [11], lower than the range reported by other national blood banks (0.13%-1.12%) [20][21][22][23][24], and below the average prevalence in Mexican blood donors reported by the PAHO (0.2%) [13]. During the 1998-2003 period, the National Blood Transfusion Center (CNTS) reported an HBsAg prevalence of 0.31% for the state of Veracruz [9].…”

Introduction: Hepatitis B and C are among the most important transfusion-transmitted infections and sources of liver diseases worldwide. In Veracruz, Mexico, liver diseases are important causes of mortality, and the prevalence reports of these viruses are scarce. This study sought to determine the prevalence of these infections in blood donors, in order to increase the safety of blood products in this region. Methodology: A retrospective study was performed on blood donors who attended the Veracruz State Blood Transfusion Center from 2006 to 2010. All samples were screened for transfusion-transmitted infections. The prevalence rates of hepatitis B virus (HBV) and hepatitis C virus (HCV) were determined, and demographic data obtained from clinical records were used to evaluate risk factors. Results: A total of 56,377 donors were serologically screened; of them, 403 were seropositive for HCV (357 men and 46 women), and 61 were positive for HBsAg (52 men and 9 women). The overall prevalence rates were 0.72% (0.63%-0.76%) for HCV and 0.11% (0.08%-0.14%) for HBsAg. The risk factors for HBsAg positivity were being a cattleman and living in the Huasteca Baja region, whereas those for HCV were being a fisherman, living in the Papaloapan region, and having an elementary-level or lower education. Conclusions: This is the first study to show that being a fisherman is a risk factor for HCV. The implementation of nucleic acid test technology will help to identify the real risks for transfusion-transmitted hepatitis C in Veracruz.

“…The 4.8% prevalence of anti-HCV antibodies found in our psychiatric population was much higher than those reported in studies of Mexican blood donors. For instance, CARRETO-VELEZ et al 1 and LADRÓN DE GUEVARA et al 5 found 1.1% and 0.8% seroprevalence of anti-HCV antibodies in large groups of Mexican blood donors, respectively. The prevalence of anti-HCV found in our psychiatric patients is also higher than that observed in blood donors in local public blood banks (less than 0.5%, unpublished data).…”

SUMMARYWe sought to determine the frequency of serological markers of selected infections in a population of psychiatric patients in Durango City, Mexico, and to determine whether there are any epidemiological characteristics of the subjects associated with the infections. One hundred and five inpatients of a public psychiatric hospital of Durango were examined for HBsAg, anti-HCV antibodies, anti-HIV antibodies, anti-Brucella antibodies, rapid plasma reagin and anti-Cysticercus antibodies by commercially available assays. Anti-Cysticercus antibodies were confirmed by Western blot and HBsAg by neutralization assay. Epidemiological data from each participant were also obtained. Seroprevalences of HBsAg, anti-HCV, anti-HIV, anti-Brucella, rapid plasma reagin and anti-Cysticercus antibodies found were 0.0%, 4.8%, 0.9%, 0.0%, 1.9%, and 0.9%, respectively. Overall, 9 (8.6%) inpatients showed seropositivity to any infection marker. We concluded that our psychiatric inpatients have serological evidence of a number of infections. HCV is an important pathogen among our psychiatric inpatients. Health care strategies for prevention and control of infections in Mexican psychiatric patients should be considered.KEYWORDS: Psychiatric patients; Infections; Prevalence; Virus; Parasite; Bacteria. INTRODUCTIONPsychiatric patients have been found to suffer from a number of infections in a higher frequency than other populations, and the prevalence of infections in psychiatric patients may vary substantially among countries. Prevalence studies indicate that psychiatric patients have a significantly higher frequency of anti-Cysticercus antibodies than those observed in the general population or healthy control subjects. In a Venezuelan study, 18.4% of the psychiatric inpatients studied were positive in the blood test for cysticercosis as compared to only 1.6% prevalence in the control group 7 . Similarly, a study carried out in Brazil showed that 5% of the patients admitted to a psychiatric hospital were positive for anti-Cysticercus antibodies while only 2.3% prevalence was found in adults of the general population group 12 . Reports also indicate that patients with mental illnesses have a high prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) infections. In an American study, researchers found that the prevalence of HIV in individuals with severe mental illness was approximately eight times the estimated US population rate, and prevalence rates of HBV and HCV were approximately five and 11 times the overall estimated population rates for these infections, respectively 10 . In an Indian study, newly registered adult psychiatric outpatients at a general hospital showed significantly higher seroprevalence of HIV infection than healthy blood donors (1.03% versus 0.5%, respectively) 11 . For its part, patients with Brucella infection may manifest central nervous system involvement, and neurobrucellosis should be considered in patients with unexplained psychiatric and neurological sym...

“…On comparing this percentage with other studies from this country and from Latin America, an increase in these infections in the female population is evident. 1,5,11,24 The increase in female donors can be attributed to greater knowledge in the general population regarding the benefi ts of donation. The increase of positive markers of infection in the female population is related to the increasing sexual liberty of the modern woman.…”

METHODS:A cross-sectional secondary data source, based on the results of biological testing of donors to a blood bank in Medellin. We determined the seroprevalence of markers of infection and were compared by sex and type of donor through frequency analysis, chi square, Fisher and prevalence ratios. RESULTS:The base population was 65,535 donors, and 3.3% had at least one positive biological test. The most prevalent marker in the blood bank testing was syphilis (1.2%), followed by trypanosomiasis (1.0%), hepatitis C virus (HCV) (0.6%), human immunodefi ciency virus (HIV) 0.5% and hepatitis B virus (HBV) (0.2%). Based on the reference laboratory found a prevalence of 0.6% for syphilis, 0.1% for (HBV) and 0% for (HCV), (HIV) and Chagas. We found statistical differences in the prevalence of (HBV) and syphilis by sex and type of donor. CONCLUSIONS:The results are consistent with the prevalences given by Pan American Health Organization and can be correlated with the global prevalence of transfusion-transmitted infections. The results founds by the blood bank lead to a transfusion risk reduction but limit the optimization of resources by excluding donors classifi ed as false positives.
