Caracterização sérica da lectina ligadora de manose (MBL) em indivíduos portadores de parasitoses intestinais

Abstract

Although the intestinal parasitosis are known since a long time and be studied since its identification, still constitute a challenge for their diagnosis and treatment. The delineation of the problem coming up in the necessity of investments in research for more accurate diagnosis, for the prompt intervention, to the existing cases and work for the prevention of risk factors that favor the emergence, maintenance and propagation of these agents. The knowledge that the host's immune competence is a limiting factor of parasitic load of various species, stimulated the research considering that the Mannosebinding lectin (MBL), a component of the complement system, is a key protein of the innate immune system, acting in the first line of defense against pathogens because it is considered acute phase. In this study, were colected 221 samples of individuals of both gender and varied ages at three different laboratories, in the period from January to April 2012. The profile of the population of the study are made and the analysis of the association between social and demographic factors with the entero-parasites and evaluated the influence of serum levels of Mannose-binding lectin (MBL) susceptibility of enteroparasitoses, distribution by age group and gender. Established also the comparison between serum concentrations of MBL of groups with identification of parasites. Statistically significant associations were observed when related protozoa E. histolytica and G.lamblia with the serum concentration of the MBL.
