The suitability of saliva for detection of glucose-6-phosphate dehydrogenase deficiency.
Saliva was investigated for its suitability as a biopsy tissue for the determination of glucose-6-phosphate dehydrogenase deficiency. It appears that there is a significant difference between the activity of the enzyme in patients and controls. However, some controls have very low values making discrimination between patients and controls using a qualitative method impossible. Glucose-6-phosphate dehydrogenase deficiency is a relevant clinical problem in many rural areas in developing countries. Existing methods for determination of the deficiency in blood and hair follicles do not meet the criteria necessary for their large scale introduction in the areas of the world that are concerned by the problem. The present study shows that saliva is not a suitable alternative. Between the three biopsy tissues compared: blood, hair follicles and saliva, hair follicles remain most attractive since their isolation hardly involves the risk of infection. A simplified method for the detection of glucose-6-phosphate dehydrogenase activity in hair follicles that would allow health service workers in the field to determine the carrier status of pregnant women might form the basis for a future kernicterus prevention programme.
