Pain, psychoaffective symptoms, and quality of life in human T cell lymphotropic virus type 1 (HTLV-1): a cross-sectional study.

The objective of this study is to describe the chronic pain characteristics in individuals infected with human T cell lymphotropic virus type 1 (HTLV-1) per subgroup (asymptomatic, oligosymptomatic, and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP)) compared with controls with chronic pain without HTLV-1. This is a cross-sectional study investigating associations between pain profile, psychopathological symptoms, and quality of life. Individuals infected with HTLV-1 refer high-intensity pain compared with controls, with more severe characteristics being present in oligosymptomatic and HAM/TSP individuals.

Factors associated with pain in individuals infected by human T-cell lymphotropic virus type 1 (HTLV-1).

Introduction: Despite the high prevalence of chronic pain in individuals infected with HTLV-1, predictive and protective factors for its development are still unclear.

Objective: To identify factors associated with chronic pain in individuals with HTLV-1.

Methods: This cross-sectional study was conducted in a reference center for treatment of patients infected with HTLV-1 in Salvador, Bahia, Brazil.
