Social Issues

Stress coverage, crisis prevention, parental education

Even after diagnosis and initiation of treatment, a small percentage of children and adults with infancy or childhood onset CAH die of adrenal crisis. Deaths from this are entirely avoidable if the child and his family understand that the daily glucocorticoids cannot be allowed to be interrupted by an illness. When a person is well, missing a dose, or even several doses, may produce little in the way of immediate symptoms. However, our glucocorticoid needs are increased during illness and stress, and missed doses during an illness such as the "flu" (or viral gastroenteritis) can lead within hours to reduced blood pressure, shock, and death.

To prevent this, all persons taking replacement glucocorticoids are taught to increase their doses in the event of illness, surgery, severe injury, or severe exhaustion. More importantly, they are taught that vomiting warrants an injection within hours of hydrocortisone (e.g., SoluCortef) or other glucocorticoid. This recommendation applies to both children and adults. Because young children are more susceptible to vomiting illnesses than adults, pediatric endocrinologists usually teach parents how to give hydrocortisone injections.

As an additional precaution, persons with adrenal insufficiency are advised to wear a medical identification tag or carry a wallet card to alert those who may be providing emergency medical care of the urgent need for glucocorticoids.

For an excellent example of parent education materials for CAH, see the booklet prepared by the Johns Hopkins Pediatric Endocrine Service.

Psychosexual development and issues

Nearly all mammals display sex-dimorphic reproductive and sexual behavior (e.g., lordosis and mounting in rodents). Much research has made it clear that prenatal and early postnatal androgens play a role in the differentiation of most mammalian brains. Experimental manipulation of androgen levels in utero or shortly after birth can alter adult reproductive behavior.

Girls and women with CAH constitute the majority of genetic females with normal internal reproductive hormones who have been exposed to male levels of testosterone throughout their prenatal lives. Milder degrees of continuing androgen exposure continue throughout childhood and adolescence due to the imperfections of current glucocorticoid treatment for CAH. The psychosexual development of these girls and women has been analyzed as evidence of the role of androgens in human sex-dimorphic behaviors.

Girls with CAH have repeatedly been reported to spend more time with "sex-atypical" toys and "rough-and-tumble" play than unaffected sisters. These differences continue into adolescent, as expressed in social behaviors, leisure activities, and career interests. Interest in babies and becoming mothers is significantly lower by most measures.

Cognitive effects are less clear and reports have been contradictory. Two studies reported spatial abilities above the average for sisters and for girls in general. Other evidence in males with and without androgen deficiencies suggest that androgens may play a role in these aptitudes.

However, gender identity of girls and women with CAH is nearly always unequivocally female. Sexual orientation is more mixed, though the majority are heterosexual. In one study, 27% of women with CAH were rated as bisexual in their orientations. Abnormalities of body image due to the effects of the disease likely play a role in the sexual development of these women, and one cannot conclude that the androgens are the major determinant of their erotic interests.
