Hepatitis C risk factor for patients submitted to dialysis

This article reports the results of the research which has evaluated the prevalence and factors associated to the presence of Hepatitis C in patients submitted to dialysis at the Clinica de Doenças Renais (Clinic of Renal Diseases) in Tubarao city (CRDT), Santa Catarina State, Brazil, in the period between January 1st, 2004 to December 31st in the same year. The prevalence of 16.8 percent of Hepatitis C in the studied population and the time-length of dialysis as significative risk factor have become evident. The non-correlation of seropositivity of the followings factors is also indicated: age, gender, base diseases, infrastructures, the type of clinic machines, the type of dialyser, used membranes, the machine sterilisation and substances for this process as well as the number of times of the dialyser reutilization. The data represented in this project suggest that the Hepatitis C presents high prevalence in patients in dialysis and the time-length of the treatment is a risky factor to acquire the infection.

Prevalência de soropositividade em doadores de sangue no centro de hematologia e hemoterapia de Criciúma - SC, no período de 2002 a 2004 / Prevalência de soropositividade em Doadores de Sangue no Centro de Hematologis e hemoterapia de Crciúma - SC, no Período de 2002 A 2004

Com o objetivo de estimar a prevalência de soropositividade entre os doadores de sangue do HEMOSC - Hemocentro de Criciúma - SC no período de janeiro de 2002 a dezembro de 2004, foi realizado um estudo transversal através da revisão da ficha do doador. Foram incluídos no estudo doadores pretensamente hígidos, de ambos os gêneros, com idade variando entre 18 e 60 anos. Os testes sorológicos aplicados ao sangue faziam parte da rotina de avaliação do doador do HEMOSC (HBsAg, Anti-HBc, Anti-HBs, Anti-HCV, HIV, Sífilis, Chagas e HTLV I/II). A amostra final foi composta por 1391 doadores com algum tipo de sorologia positiva em um universo de 34.893 doadores no período estudado. A prevalência de soropositividade variou de 3,87% a 4,09%. Do total de soropositivos, 74,7% eram do gênero masculino e 25,3% do gênero feminino. A faixa etária predominante entre os doadores soropositivos estava compreendida entre 31-60 anos (66,9%). Com relação ao estado civil, notou-se uma prevalência de soropositividade de 74,1% entre os casados e 25,9% entre os solteiros. A sorologia prevalente entre os doadores soropositivos foi Anti-HBc (72,5%). O percentual de doadores positivos para mais de uma sorologia foi de 61,1%.

In order to evaluate the prevalence of tested positivity among blood donors of HEMOSC - Hemocentro of Criciúma - SC, from January of 2002 to December of 2004, was performed a transversal study through of examination to the donors medical chart.

The final sample took part 1391 donors with some positive serology in a universe of 34893 donors in the studied periods. The prevalence of tested positivity varied from 3, 87% to 4, 09%. From the total of tested positivity, 74,7% were males and 25,3% were females. The prevalent age among tested positivity donors were about 31-60 years old. About marital status, it was noticed a prevalence of tested positivity of 74,1% among the married ones, 25,9% among single ones.
