“…In the South and South Eastern regions, HTLV prevalence ranged from 0.02% to 1.5% [ 302 , 303 , 305 , 318 , 321 , 322 , 358 , 367 , 368 , 369 , 370 ]. In urban Northern and Southern regions HTLV-1 prevailed over HTLV-2 [ 309 , 310 , 313 , 314 , 317 , 358 ]. The central region exhibited HTLV prevalence ranging from 0.02% to 1.6% [ 305 , 307 , 315 , 316 , 317 , 371 , 372 , 373 , 374 ], of which, for the Amazonian region, prevalence increased when indigenous villages were analyzed: 0.4–1.18% HTLV positivity in the city [ 375 , 376 , 377 , 378 ], whereas, in certain villages, the prevalence increased up to 13.88% [ 376 , 379 , 380 , 381 , 382 , 383 ].…”

The Epstein–Barr virus (EBV), Kaposi sarcoma herpesvirus (KSHV) and human T-lymphotropic virus (HTLV-1) are lymphomagenic viruses with region-specific induced morbidity. The RIAL-CYTED aims to increase the knowledge of lymphoma in Latin America (LA), and, as such, we systematically analyzed the literature to better understand our risk for virus-induced lymphoma. We observed that high endemicity regions for certain lymphomas, e.g., Mexico and Peru, have a high incidence of EBV-positive lymphomas of T/NK cell origin. Peru also carries the highest frequency of EBV-positive classical Hodgkin lymphoma (HL) and EBV-positive diffuse large B cell lymphoma, not otherwise specified (NOS), than any other LA country. Adult T cell lymphoma is endemic to the North of Brazil and Chile. While only few cases of KSHV-positive lymphomas were found, in spite of the close correlation of Kaposi sarcoma and the prevalence of pathogenic types of KSHV. Both EBV-associated HL and Burkitt lymphoma mainly affect young children, unlike in developed countries, in which adolescents and young adults are the most affected, correlating with an early EBV seroconversion for LA population despite of lack of infectious mononucleosis symptoms. High endemicity of KSHV and HTLV infection was observed among Amerindian populations, with differences between Amazonian and Andean populations.

“…Blood donation is one of the noblest gestures a human can make when its purpose is to save lives (1) . Although blood transfusions were seen as a mere transmission of physiological material, changes occurred that made the screening of donors highly relevant to the quality of blood.…”

BackgroundSo that an improvement in the selection of donors can be achieved and the risk to the recipient of transfused blood can be reduced, prospective donors are submitted to clinical and serological screening. ObjectiveThis study investigated the blood discard rate and the rate of infectious and contagious diseases in blood donors from provincial towns of the state of Paraná, Brazil. MethodsThis study was an exploratory cross-sectional descriptive investigation with a quantitative approach of donations between January and December 2011. ResultsIn the study period the Regional Blood center in Maringá, Brazil received 8337 blood donations from people living in the city and neighboring towns. However, 278 (3.33%) donations were discarded during serological screening owing to one or more positive serological markers. A total of 46.4% of the discarded blood units were confirmed positive by serology with anti-HBc being the most common (66.7%), followed by syphilis (22.5%), HBsAg (4.7%), anti-hepatitis C virus (3.1%), human immunodeficiency virus (1.5%) and Chagas' disease (1.5%). The rate of infectious-contagious diseases that can be transmitted by blood transfusions was 1.55% (129/8337) of the donor population with a frequency of 1.03% for anti-HBc and 0.35% for syphilis. ConclusionThis study demonstrates a high prevalence of the anti-HBc marker in prospective blood donors from provincial towns in the state of Paraná, Brazil.

HTLV II em doadores de sangue na Hemorrede do Ceará – HEMOCE

Abstract: Although HTLV-II infection is low, its presence is universal, being similar in males and females mostly in urban centers. The need of preventive measures as a way of avoiding infection spread is stressed.
