Limited protective effect of the CCR5Delta32/CCR5Delta32 genotype on human immunodeficiency virus infection incidence in a cohort of patients with hemophilia and selection for genotypic X4 virus.

The relationship among CCR5 genotype, cytomegalovirus infection, and disease progression and death was studied among 159 human immunodeficiency virus (HIV)-infected patients with hemophilia. One patient (0.6%) had the CCR5Delta32/CCR5Delta32 genotype (which occurs in approximately 2% of the Scandinavian population) and a rapid disease course.

[Beta-thalassemia major in children and adolescents in Denmark].

Introduction: Beta-thalassemia major occurs with increasing frequency among Danish children as a result of immigration. The aim of the study was to estimate the occurrence of beta-thalassemia major in Denmark, analyse the treatment and organ functions, and identify areas for an improved treatment strategy.

Material And Methods: During 1998-99 all Danish pediatric departments were contacted for identification of children aged 0-18 years with beta-thalassemia major.
