Molecular characterization of glucose-6-phosphate dehydrogenase gene defect in the Kuwaiti population.

Context: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common human enzyme deficiencies. More than 130 different molecular abnormalities have been described worldwide, with considerable variation in the enzyme among various racial groups. Data from Kuwaiti populations are scarce, and the studies available are the result of screening male blood donors who may not be truly representative of the Kuwaiti population.

Lymphocyte subsets in healthy adult Kuwaiti Arabs with relative benign ethnic neutropenia.

Relative and absolute neutropenia is frequently seen in the healthy adult Kuwaiti Arab population. Fluorescent monoclonal antibody labelling followed by flow cytometry was used to determine the lymphocyte subsets in 48 normal healthy individuals in the Kuwaiti adult population (24 males and 24 females, age 17-59 years) with relative or absolute neutropenia, and this was compared to age-matched controls (64 males and 63 females). The mean haemoglobin levels were 13.

Reference values of lymphocyte subsets in the normal healthy adult Kuwaiti Arab population.

Fluorescent monoclonal antibody labelling followed by a lysed whole blood method and flow cytometry was used to determine the lymphocyte subpopulations in 127 (64 males and 63 females) normal healthy individuals in the adult (age 18-59 years) Kuwaiti population. Relative percentages and absolute values of CD2+, CD3+, CD19+, CD4+, CD8+, HLADR+, CD56+, CD45RO+, and CD45RA+ cells were determined. The reference ranges were CD2+, 73-92% (0.
