Human T Lymphotropic Virus Type 1 Infection and Gastric Cancer Development in Japan

Human T lymphotropic virus type 1 infection and gastric cancer development in Japan.

BACKGROUND The rate of human T lymphotropic virus type 1 (HTLV-1) positivity among residents of Kamigoto, Japan, is extremely high (15%). Although the rate of Helicobacter pylori positivity in Kamigoto is almost the same as that in other areas of Japan, the incidence of gastric cancer in Kamigoto is lower. This study examined whether HTLV-1 infection affects H. pylori infection and the developm...

Evaluating the Frequency of Human T-Lymphotropic Virus Type 1 Infection in Iranian Population

Background: Human T-cell lymphotropic viruses 1 (HTLV1) is endemic in specific regions. We aimed to determine the prevalence of HTLV I infection among blood donors in southeast Iran.   Methods: This cross-sectional study was conducted between April 2005 and March 2015. Sera were collected from blood donors and were tested for the presence of HTLV1 specific antibody using ELISA. Reactive sample...

Frequency of Human T-Cell Lymphotropic Virus (HTLV) Type 1 and 2 Infection in HIV Infected Patients

Background and Objectives: Human T-cell lymphotropic viruses (HTLV) type 1 and 2 are retroviruses that share the same routes of transmission as human immunodeficiency virus (HIV). As a consequence of epidemiologic similarities, HIV and HTLV-1/2 co-infection is frequent. Due to the limited data, this study assessed the seroprevalence of HTLV-1/2 infections in HIV infected patients in Tehran, Ira...

Study of the Association Between Human T-cell Lymphotropic Virus Type I Infection and Lichen Planus

Tuberculosis and human T-cell lymphotropic virus type 1 infection.

SIRIn a recent review of the infectious complications of human T-cell lymphotropic virus type I (HTLV-I) infection, Marsh [1] suggested that those individuals infected with HTLV-I may be at increased risk of tuberculosis. This risk may be due to reduced delayed-type hypersensitivity to PPD in asymptomatic patients infected with HTLV-l. Up to 14% of the population in Papua New Guinea are infecte...
