6-Mercaptopurine is extensively used in the treatment of childhood lymphoblastic leukaemia to prolong the duration of remission achieved with other drugs. The response to remission maintenance therapy varies widely. We investigated the relationship between red blood cell 6-thioguanine nucleotide, a metabolite of 6-mercaptopurine, and myelosuppression in 22(More)
Twelve boys and 10 girls on similar long term remission maintenance treatment for lymphoblastic leukaemia had 79 random assays of their red cell 6 thioguanine nucleotide ( 6TGN ) concentrations performed as an index of cytotoxic activity generated by oral 6-mercaptopurine ( 6MP ). Correlation between the dose of 6MP and 6TGN was statistically significant in(More)
The effect of cotrimoxazole on the utilization of 6-mercaptopurine (6MP) was studied in a group of children receiving remission maintenance treatment for lymphoblastic leukaemia (ALL). This was done by measuring the level of an active metabolite of 6MP, 6-thioguanine nucleotide (6TGN), and comparing it both with the drug dose and with subsequent neutropenia(More)

Children with human immunodeficiency virus (HIV) have an increased risk of developing Kaposi Sarcoma (KS) and non-Hodgkin lymphoma (NHL) compared to HIV-negative children. We compiled currently published epidemiologic data on KS and NHL among children in sub-Saharan Africa (SSA). Among countries with available data, the median incidence of KS was(More)
BACKGROUND Rural women in West Bengal have been found to have low rates of formal education, poor health knowledge, high rates of malnutrition and anemia, and low levels of empowerment. Despite these difficult circumstances, some women have positive health outcomes compared to women with similarly disadvantaged backgrounds. The purpose of this study is to(More)
Adolescent girls in India carry a disproportionate burden of health and social risks; girls that do not finish secondary education are more likely to have an earlier age of sexual initiation, engage in risky sexual behavior, and consequentially be at greater risk of dying from pregnancy-related causes. This paper presents a comparison of girls in school and(More)
