The human T-cell lymphotropic virus type I and II (HTLV-IIII) are retrovirus that can be transmitted through blood transfusion. These virus are associated with tropical spastic paraparesis (TSP), adult T-cell leukemia/lymphoma (ALT/L) and other immunomediated systemic diseases. In this study, clinic symptoms related to these virus have ivestigated to use in clinical screening of the candidates for blood donation. It used standard procedures to clinical evaluation from 30 blood donors in Tropical Medicine ambulatory of the Universidade Federal do Para, seropositives for HTLV-UII, confirmated by the polymerase chain reation method. Fourty blood donors candidates, that was chosen ramdomily, It studied as a control group through complementary clinical inquiry. Thirty patients studied, 23 of these were HTLV-I positive and 07 HTLV-II positive. The symptons referred in the evaluation, some patients referred more thar one, 15 patients (50%) did not referred any symptoms, and the other (50%) presented many kinds of symptoms, however, 12 presented only neurological symptoms. Five patients presented tingles, 05 muscular force decrease, 04 constipation, 02 paresthesia, 02 subcutaneous nodes, 01 urinary incontinence, 01 smudgy vision, and 01 libido decrease. In the control group, 05 candidates referred neurological symptoms. The results of this study indicate that symptoms such as, muscular force decrease and tingles have to asked to blood donors candidates in order to reduce the risk of transfusional infection.

Paroxysmal nocturnal hemoglobinuria is a hematological disease with complex physiopathology. It is genetically characterized by a somatic mutation in the PIG-A gene (phosphatidylinositol glycan anchor biosynthesis, class A), in which the best known antigens are DAF (decay accelerating factor or CD55) and MIRL (membrane inhibitor of reactive lysis or CD59). OBJECTIVE: To determine the frequency of paroxysmal nocturnal hemoglobinuria in patients attended at the HEMOPA foundation from November 2008 to July 2009. METHOD: Thirty patients, with ages ranging from two to 79 years old and suspected of having paroxysmal nocturnal hemoglobinuria were examined. All patients were immunophenotyped by flow cytometry for the CD5, CD59, CD16 and CD45 antigens. RESULTS: Paroxysmal nocturnal hemoglobinuria was identified in nine of the thirty patients investigated. Another 3 cases had inconclusive results with CD59-negative labeling only for neutrophils. The highest frequency of paroxysmal nocturnal hemoglobinuria patients (7/9) and inconclusive cases (2/3) were between 19 years old and 48 years old, with a median of 28 years. CONCLUSION: These results show the importance of flow cytometry to identify cases in which patients are deficient in only one antigen (CD59).
