          Abstract

          The treatment of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is complex. In addition to disease control, important therapeutic goals are the maintenance of normal growth and the acquisition of normal reproductive function. Here, data regarding final adult height (FH) in patients with CAH will be reviewed. Additional difficulties associated with CAH, including risks of obesity and hypertension, will be discussed. Information about fertility and reproductive outcomes in men and women with CAH will also be summarized. Although the treatment of each child with CAH needs to be individualized, close medical followup and laboratory monitoring along with good compliance can often result in positive clinical outcomes.

          High prevalence of testicular adrenal rest tumors, impaired spermatogenesis, and Leydig cell failure in adolescent and adult males with congenital adrenal hyperplasia.

          N Stikkelbroeck, B Otten, A Pasić … (2001)
          In male patients with congenital adrenal hyperplasia, testicular tumors, or so-called adrenal rest tumors, have been described, but their presence in well controlled patients is thought to be rare. In this study, the prevalence of testicular tumors in 17 adolescent and adult male patients with congenital adrenal hyperplasia (age, 16-40 yr) was investigated. In 16 of 17 patients, one or more testicular tumors, ranging in maximal length from 0.2-4.0 cm, were found on ultrasonography. In 6 patients, the testicular tumors were palpable. Undertreatment, defined as the presence of a salivary androstenedione level (mean of 6 saliva samples collected over 24 h with intervals of 4 h) above the upper reference morning level, was found in 5 of 17 patients at the time of investigation. The other 12 patients were treated adequately or even over treated at the time of investigation. Nevertheless, 11 of these 12 patients showed testicular tumors on ultrasonography. Neither the presence of undertreatment at the time of investigation nor characteristics of the therapeutic regimen (daily dose of hydrocortisone equivalents per body surface, the use of glucocorticoid medication either two or three times a day, or the time of taking the highest glucocorticoid dose either in the morning or the evening) could predict tumor size (maximal diameter of largest tumor). In patients who were heterozygous or homozygous for the deletion or conversion of the CYP21 gene, tumor size was significantly larger than in patients who did not have this genotype. Impairment of Leydig cell function as manifested by decreased plasma levels of T was found in 6 of 17 patients. Semen analysis in 11 patients revealed azoospermia in 3 patients and poor semen quality in 4 patients. We conclude that, when carefully sought for, testicular adrenal rest tumors are frequently present in adolescent and adult males with congenital adrenal hyperplasia and are often accompanied by impaired spermatogenesis and Leydig cell failure.

            Reduced final height outcome in congenital adrenal hyperplasia under prednisone treatment: deceleration of growth velocity during puberty.

            Susanne Pozza, Dietrich Knorr, Maximilian Schmidt … (2007)
            Normal to decreased final height (FH) has been reported in patients with congenital adrenal hyperplasia (CAH). The objective was to determine FH outcome and influences of steroid treatment. The effects of glucocorticoid treatment for classical CAH were retrospectively studied in 125 patients (77 females). Growth pattern, FH, and pubertal development were recorded. Corrected FH was in the lower range of genetic potential [females with simple virilizing (SV)-CAH, -0.6 +/- 1.0 sd score (SDS) vs. females with salt-wasting (SW)-CAH, -0.6 +/- 0.9 SDS; males with SV-CAH, -1.1 +/- 0.9 SDS vs. males with SW-CAH, -0.9 +/- 0.9 SDS]. Total pubertal growth was significantly reduced in comparison with a reference population (females with SV-CAH, 11.9 +/- 6.5 cm, and females with SW-CAH, 13.8 +/- 7.6 cm vs. reference 20.3 +/- 6.8 cm, P < 0.01; and males with SV-CAH, 15.4 +/- 6.6 cm, and males with SW-CAH, 18.5 +/- 6.9 cm vs. reference 28.2 +/- 8.2 cm, P < 0.01). Thirty-three patients had been treated with prednisone, which resulted in reduced FH compared with patients (n = 92) treated with hydrocortisone (-1.0 +/- 0.9 SDS vs.-0.6 +/- 0.9 SDS; P < 0.05). FH correlated negatively with hydrocortisone dose given at the start of puberty (r = -0.3; P < 0.05). Pubertal development started early in boys [9.8 +/- 2.3 yr (SV) and 10.6 +/- 1.9 yr (SW)] and was timely in girls [9.8 +/- 1.9 yr (SV) and 10.3 +/- 1.5 yr (SW), menarche at 13.3 +/- 1.7 yr (SV) and 13.7 +/- 1.5 yr (SV)]. Patients with CAH are able to achieve adequate FH with conventional therapy. Total pubertal growth is significantly decreased, and treatment with prednisone results in decreased FH. In addition to biochemical analysis, treatment should be adjusted to normal growth velocity, especially during puberty.

              Impaired sexual and reproductive outcomes in women with classical forms of congenital adrenal hyperplasia.

              L Duranteau, C Bouvattier, E Thibaud … (2007)
              The objectives of the study were 2-fold: 1) a detailed description of sexual and reproductive outcomes in adult women with congenital adrenal hyperplasia (CAH) of different phenotypic severity at birth; and 2) comparisons of these outcomes among CAH subtypes and between CAH women and non-CAH control women. This was a cross-sectional study using a face-to-face interview, a written questionnaire, the Female Sexual Function Index, and a gynecological examination. Patients included 35 women with CAH, representing Prader stages I-V at birth, aged 18-43 yr, who had been treated from birth to adolescence in the same pediatric endocrine clinics. Sixty-nine non-CAH healthy control women were selected from hospital-staff families. None of the CAH women expressed doubts about their gender assignment. Twenty percent (seven of 35) had homosexual inclinations; 23% (eight of 35) were married; three reported a complete lack of sexual activity; and 37% (13 of 35) said they never had heterosexual intercourse with vaginal penetration. Sexual functioning as assessed by the Female Sexual Function Index was much lower in CAH women than controls and lowest in CAH women with high Prader stages. Eighty-one percent (18 of 22) experienced pain during vaginal penetration. Only eight women became pregnant, and 17% (six of 35) had children. Despite expert medical and surgical care by physicians dedicated to this rare disease, women with CAH still suffer major limitations in their sexual function and reproductive life.
