1. Serologic strategy in detecting RHD altered alleles in Brazilian blood donors
ABSTRACT Background: We evaluated different technological approaches and anti-D clones to propose the most appropriate serologic strategy in detecting the largest numbers of D variants in blood donors. Methods: We selected 101 samples from Brazilian blood donors with different expressions of D in our donor routine. The tests were performed in immediate spi

2. Specific antigen serologic tests in leprosy: implications for epidemiological surveillance of leprosy cases and household contacts
BACKGROUND There is a lack of straightforward tests for field application and known biomarkers for predicting leprosy progression in infected individuals. OBJECTIVE The aim was to analyse the response to infection by Mycobacterium leprae based on the reactivity of specific antigens: natural disaccharide linked to human serum albumin via an octyl (NDOHSA)

3. Evolution of hepatitis B serological markers in HIV coinfected patients: a case study
ABSTRACT OBJECTIVE To describe the evolution of serological markers among HIV and hepatitis B coinfected patients, with emphasis on evaluating the reactivation or seroreversion of these markers. METHODS The study population consisted of patients met in an AIDS Outpatient Clinic in São Paulo State, Brazil. We included in the analysis all HIV-infected and

4. Benznidazole therapy for Chagas disease in asymptomatic Trypanosoma cruzi -seropositive former blood donors: evaluation of the efficacy of different treatment regimens
Abstract: INTRODUCTION: Chagas disease currently affects 5.7 million people in Latin America and is emerging in non-endemic countries. There is no consensus concerning the efficacy of trypanocidal therapy for patients with the chronic form of the disease. We evaluated cardiac function and sociodemographic, clinical, and serologic characteristics of a group

5. Factors associated with seropositivity for APGL-Iamong household contacts of leprosy patients
Abstract: INTRODUCTION: Leprosy is mainly transmitted among family members who share genetic and ambient factors. The clinical form of leprosy in the index case and kinship could be risk factors for leprosy transmission. High antibody levels in household contacts (HC) in the absence of neural or skin lesions may characterize latent infection. This study aim

6. Impact of a confirmatory RhD test on the correct serologic typing of blood donors
BACKGROUND: The RHD gene is highly polymorphic, which results in a large number of RhD variant phenotypes. Discrepancies in RhD typing are still a problem in blood banks and increase the risk of alloimmunization. In this study, the RhD typing strategy at a blood bank in Brazil was evaluated.METHODS: One-hundred and fifty-two samples typed as RhD negative and

7. Comparison of recombinant A2-ELISA with rKE16 dipstick and direct agglutination tests for diagnosis of visceral leishmaniasis in dogs in Northwestern Iran
INTRODUCTION: Various methods are used for the diagnosis of visceral leishmaniasis (VL), such as microscopic examination, culture and inoculation of laboratory animals; however, serological assays are commonly used for the detection of antibodies in serum samples with a wide range of specificity and sensitivity. METHODS: The purpose of this study was to com

8. The combination of three faecal parasitological methods to improve the diagnosis of schistosomiasis mansoni in a low endemic setting in the state of Ceará, Brazil
Laboratory diagnosis of intestinal schistosomiasis mansoni can be accomplished through various methods of stool examination to detect parasites, ranging from the most classic tests (Kato-Katz) to several methods that are still undergoing validation. This study was conducted to assess two new parasite identification methods for diagnosing schistosomiasis mans

9. Effectiveness of confidential unit exclusion in screening blood donors of the regional blood bank in Londrina, Paraná State
BACKGROUND: For transfusion purposes, blood donors must be accepted both in clinical and serological evaluations and must not have excluded their own donation using the confidential unit exclusion. AIMS: The objective of this study was to verify whether blood donors who choose self exclusion are more likely to be positive in serological tests than donors who

10. Chronic hepatitis virus infection in patients with multiple myeloma: clinical characteristics and outcomes
OBJECTIVES: Cytotoxic agents and steroids are used to treat lymphoid malignancies, but these compounds may exacerbate chronic viral hepatitis. For patients with multiple myeloma, the impact of preexisting hepatitis virus infection is unclear. The aim of this study is to explore the characteristics and outcomes of myeloma patients with chronic hepatitis virus

11. Diagnostico molecular da Leishmaniose visceral canina: avaliação do swab conjuntival em cães assintomáticos e em cães vacinados / Molecular diagnosis of canine visceral leishmaniasis: conjunctival swab evaluation in asymptomatic dogs and vaccinated dogs
The epidemiological control of visceral Leishmaniasis (VL) in Brazil involves the elimination of infected dogs. Therefore, reliable diagnostic tests are essential to prevent the transmission of the disease or unnecessary culling of dogs. The VL control in Brazil is based on serological surveys, nevertheless serologic assays present problems related to sensit

12. Prevalência da doença celíaca em crianças desnutridas, na faixa etária de 12 a 36 meses
Background: The correct diagnosis of celiac disease (CD) in environmentally deprived children is frequently hindered by the common presence of other causes for the classical CD symptoms: malnutrition, failure to thrive and frequent diarrheas. Objectives: To determine the prevalence of CD in a group of 12 to 36 month-old children using immunoglobulin antibodi
