HTLV screening and confirmatory testing among blood donors in São Paulo: A cross‐sectional study

Transfusion Medicine, EarlyView.
Abstract Introduction Human T‐cell lymphotropic virus types 1 and 2 (HTLV‐1/2) are transfusion‐transmissible retroviruses associated with severe diseases, and blood donor screening is mandatory in Brazil. Increasing HTLV‐related discard rates at our institution prompted this study to determine the prevalence and incidence of HTLV‐1/2 and to investigate

Human Immunodeficiency Virus-Infected Individuals Contain Provirus in Small Numbers of Peripheral Mononuclear Cells and at Low Copy Numbers [PDF]

, 1990
In human immunodeficiency virus (HIV)-infected individuals, the proportion of circulating mononuclear cells (PBMCs) which carry HIV provirus and the number of HIV proviral sequences per infected PBMC have been matters for conjecture.

Nectin-2 Acts as a Viral Entry Mediated Molecule That Binds to Human Herpesvirus 6B Glycoprotein B

Viruses, 2022
Human herpesvirus 6B (HHV-6B) is a T-lymphotropic virus and the etiological agent of exanthem subitum. HHV-6B is present in a latent or persistent form after primary infection and is produced in the salivary glands or transmitted to this organ.

Is the innate bio-protection power against human virus the same between males and females? A conclusion based on blood donor data of HTLV-I infection [PDF]

, 2008
Human T-cell leukemia virus type I (HTLV-I) is a retrovirus that causes adult T-cell leukemia. The male-to-female transmission is stronger than the reverse, so the carrier proportion of women is greater than that of men.

Fratricide among CD8+ T Lymphocytes Naturally Infected with Human T Cell Lymphotropic Virus Type I [PDF]

, 2000
Infection and gene expression by the human T lymphotropic virus type I (HTLV-I) in vivo have been thought to be confined to CD4+ T lymphocytes. We show here that, in natural HTLV-I infection, a significant proportion of CD8+ T lymphocytes are infected by

Revista do Instituto de Medicina Tropical de São Paulo, 2017
Human T-lymphotropic virus type 1 and 2 (HTLV-1/2) is endemic in Brazil, but few studies have investigated the seroprevalence of HTLV and its subtypes among blood donors in the capital city Manaus, Amazonas State, Brazil.To estimate the seroprevalence of HTLV-1/2 and to identify circulating subtypes among blood donors in Manaus.Blood donors (2001-2003)

Spread of Human T-Lymphotropic Virus 1 and 2 Among Relatives of People Who Use Illicit Drugs in Northern Brazil

Frontiers in Microbiology, 2022
The human T-lymphotropic virus 1 (HTLV-1) and 2 (HTLV-2) can be transmitted between humans by mechanisms associated with horizontal and vertical routes. Recently, high prevalence rates and levels of genetic diversity for HTLV-1 and HTLV-2 were detected among people who use illicit drugs (PWUDs) in the Brazilian state of Pará.

Allogeneic Hematopoietic Stem Cell Transplantation Achieves Durable Remission in Blast‐Phase Chronic Myeloid Leukemia Presenting as Early T‐Cell Precursor Acute Lymphoblastic Leukemia

eJHaem, Volume 7, Issue 5, October 2026.
ABSTRACT Introduction The presentation of chronic myeloid leukemia (CML) in the blast phase as early T‐cell precursor acute lymphoblastic leukemia (ETP‐ALL) is very rare. As previously reported, in contrast to B‐ALL, the prognosis is poor. Case Presentation We encountered a patient with blast phase CML presenting as ETP‐ALL.

Oral Relapsing Lymphomatoid Papulosis: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Lymphomatoid papulosis (LyP) is a CD30+ T‐cell lymphoproliferative disorder rarely involving mucosa, where it may mimic aggressive lymphomas. This case highlights its chronic relapsing course, diagnostic challenges with ALK‐negative anaplastic T‐cell lymphoma, and the importance of long‐term follow‐up despite a favorable prognosis.
