Human Leptospirosis: Seroreactivity and Genetic Susceptibility in the Population of Sao Miguel Island (Azores, Portugal)

  • Autores: Branco CC, Bulhoes SM, Cabral R, Esteves LM, Mota FM, Mota-Vieira ML, Paiva C, Vieira ML
  • Ano de Publicação: 2014
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25255143

We conducted, in 2011, a retrospective hospital-based case-control study in the São Miguel Island population (Azores archipelago). In order to determine the seropositivity against pathogenic Leptospira after the first episode of leptospirosis, we performed a serological evaluation in 97 unrelated participants diagnosed with leptospirosis between 1992 and 2011.

Pneumocystis and Pneumocystosis: first meeting of experts from Latin-American and Portuguese-speaking countries – a mini-review

  • Autores: Calderon EJ, de Armas Y, Esteves F, Matos O, Medrano FJ, Wissmann G
  • Ano de Publicação: 2014
  • Journal: Expert Review of Anti-infective Therapy
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24617414

The epidemiological studies presented in this meeting begin to change the misconception that since the AIDS epidemic, Pneumocystis pneumonia (PcP) has become an infrequent disease, showing that today PcP remains a major opportunistic infection in HIV-infected patients in both developed and developing countries and an emerging problem in immunocompromised patients without HIV infection worldwide.

(1-3)-Beta-D-glucan in association with lactate dehydrogenase as biomarkers of Pneumocystis pneumonia (PcP) in HIV-infected patients

  • Autores: Antunes F, Badura R, de Sousa B, Esteves F, Fernandes C, Gaspar JF, Lee CH, Matos O, Seringa M
  • Ano de Publicação: 2014
  • Journal: European Journal of Microbiology & Infectious Diseases
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24487911

Pneumocystis pneumonia (PcP) is a major HIV-related illness caused by Pneumocystis jirovecii. Definitive diagnosis of PcP requires microscopic detection of P. jirovecii in pulmonary specimens. The objective of this study was to evaluate the usefulness of two serum markers in the diagnosis of PcP. Serum levels of (1-3)-beta-d-glucan (BG) and lactate dehydrogenase (LDH) were investigated in 100 HIV-positive adult patients and 50 healthy blood donors.

Toxoplasma gondii prevalence in cats from Lisbon and in pigs from centre and south of Portugal

  • Autores: Aguiar D, Antunes F, Costa ML, de Sousa B, Esteves F, Matos O, Rosado J
  • Ano de Publicação: 2014
  • Journal: Veterinary Parasitology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24418601

Toxoplasmosis is an important zoonosis worldwide. Here we determined the presence of Toxoplasma gondii antibodies in sera and T. gondii DNA in faeces of 215 domestic cats from veterinary clinics in the Lisbon area; 44 (20.5%) had anti-T. gondii IgG antibodies by the modified agglutination test (cut-off 1:40) and DNA was detected in 16 (35.6%) of 45 cat faeces tested.

HIV Risky Sexual Behaviors and HIV Infection among Immigrants: A Cross-Sectional Study in Lisbon, Portugal

  • Autores: Dias S, Gama A, Marques A, Martins MO
  • Ano de Publicação: 2014
  • Journal: International Journal of Environmental Research and Public Health
  • Link: http://www.mdpi.com/1660-4601/11/8/8552

This study aimed to examine risky sexual behavior, its associated factors and HIV infection among immigrants. A participatory cross-sectional survey was conducted with 1187 immigrants at the National Immigrant Support Centre, in Lisbon (52.2% female; 34.0% Africans, 33.8% Brazilians, 32.2% Eastern Europeans). About 38% of participants reported ≥2 sexual partners in the previous year, 16.2% both regular and occasional sexual partners (last 12 months), 33.1% inconsistent condom use with occasional partners, and 64% no condom use in the last sexual intercourse.
