10 out of 17 (59%) patients with tropical spastic paraparesis (TSP) had antibodies to human T-lymphotropic virus-I (HTLV-I), as did 5 out of 5 TSP patients with systemic symptoms. Only 13 out of 303 (4%) controls, made up of blood donors, medical personnel, and other neurological patients, had such antibodies. These findings suggest either that HTLV-I is(More)
BACKGROUND The evolution of HIV-1 and its immune escape to autologous neutralizing antibodies (Nabs) during the acute/early phases of infection have been analyzed in depth in many studies. In contrast, little is known about neither the long-term evolution of the virus in patients who developed broadly Nabs (bNabs) or the mechanism of escape in presence of(More)
An increase in the number of new HIV diagnoses among men who have sex with men (MSM) has been observed in several countries in the early 2000s. In this article, we explore the trends in MSM in France between 2003 and 2008. To estimate the number of MSM newly diagnosed with HIV, we take into account the reporting delay, underreporting and missing data for(More)
OBJECTIVES To describe HIV-1 variants circulating in Mali and to estimate the rate of transmission of HIV-1 drug resistance in 2006. PATIENTS AND METHODS Viral reverse transcriptase (RT) and protease (PR) genes from 198 antiretroviral (ARV)-naive patients diagnosed HIV-1 positive in May 2006 in Bamako and Segou were sequenced. RESULTS Although CRF02_AG(More)
A large cross-sectional serologic survey for human T cell leukemia virus type 1 (HTLV-1) antibody was conducted in 3,177 Ivory Coast residents to evaluate the prevalence of HTLV-1 and to determine possible risk factors and correlates of HTLV-1 infection. Of the 3,177 serum samples, 110 (3.5%) were positive for antibody to HTLV-1 by indirect(More)

The blood borne viruses must be separated into major and minor agents. Major viruses transmissible by blood transfusion are human immunodeficiency virus (HIV) and hepatitis B and C viruses (respectively HBV, HCV). The prevalence of virological markers in French blood donors has been continuously decreasing since the implementation of serological screening(More)
Three doses of inactivated hepatitis B vaccine were given at one-month intervals to Senegalese children aged less than two years. A control group received diphtheria/tetanus/polio vaccine. Of those HB vaccine recipients who were seronegative before immunisation, 94.5% had a specific anti-HBs response. Anti-HBs of maternal origin did not interfere with the(More)
OBJECTIVES To estimate the prevalence of transmitted drug resistance mutations and non-B subtype circulation in antiretroviral-naive chronically HIV-1-infected patients in France. METHODS Resistance mutations were sought in samples from 530 newly diagnosed HIV-1-infected patients from October 2006 to March 2007. Protease and reverse transcriptase(More)
At least 10 different genetic human immunodeficiency virus type 1 (HIV-1) subtypes (A-J) are responsible for the AIDS pandemic. Much of the understanding of HIV-1 disease progression derives from studies in the developed world where HIV infection is almost exclusively subtype B. This has led many to question whether the properties and consequences of HIV-1(More)
