A serological follow-up of toxocariasis patients after chemotherapy based on the detection of IgG, IgA, and IgE antibodies by enzyme-linked immunosorbent assay.

A serological follow-up study was carried out on 27 children (1–12 years old) with visceral and/or ocular toxocariasis, after treatment with thiabendazole. A total of 159 serum samples were collected in a period ranging from 22–116 months. Enzyme-linked immunosorbent assays (IgG, IgA, and IgE ELISA) were standardized, using excretory–secretory antigens obtained from the second-stage larvae of a Toxocara canis culture. The sensitivity found for the IgG, IgA, and IgE ELISA, as determined in visceral toxocariasis patients, was 100%, 47.8%, and 78.3%, respectively. Approximately 84% of the patients presented single or multiple parasitosis, as diagnosed by stool examination, yet such variables did not appear to affect the anti-Toxocara immune response. Titers of specific IgE antibody showed a significant decrease during the first year after treatment, followed by a decrease in the IgA titers in the second year, and in the IgG titers from the fourth year onwards. Sera from all patients presented high avidity IgG antibodies, indicating that they were in the chronic phase of the disease. Moreover, 1 year after treatment, the level of leukocytes, eosinophils, and anti-A isohemagglutinin in patients decreased significantly. The present data suggest that IgE antibodies plus eosinophil counts are helpful parameters for patient followup after chemotherapy.

Trabalho e qualidade de vida relacionada à saúde de pacientes em diálise peritoneal

OBJETIVO: Descrever e comparar a Qualidade de Vida Relacionada à Saúde (QVRS) de pacientes em Diálise Peritoneal (DP) que tinham ou não trabalho remunerado. MÉTODOS: Estudo seccional e populacional com 82 pacientes dos dois serviços de DP de Ribeirão Preto, (SP). A coleta de dados foi realizada por entrevistas entre dezembro/2009 e março/2010. Os questionário para caracterização dos pacientes, o Miniexame do Estado Mental e o Kidney Disease and Quality of Life-Short Form foram usados. Foram feitas as análises estatística exploratória uni e bivariada e a confirmatória bivariada entre variáveis independentes e as dimensões de QVRS. RESULTADOS: os pacientes com trabalho remunerado apresentavam maiores escores médios refletindo melhor QVRS para a maioria das dimensões do instrumento utilizado. CONCLUSÃO: o trabalho é uma faceta importante da vida desses pacientes e merece a atenção dos profissionais da saúde na busca de estratégias que favoreçam e incentivem sua manutenção e reinserção no mercado de trabalho.
