Clinical practice guidelines on Congenital Adrenal Hyperplasia (CAH) give a brief review of epidemiology, etiology and pathogenesis of all disease causative steroidogenic defects. Recommendations on neonatal screening and management of early-diagnosed CAH due 21-hydroxylase deficiency were given in details. We also included the algorithm for the hormonal treatment and management of the patients of different age. Prenatal and preimplantation genetic diagnosis of 21-hydroxylase deficiency has been also discussed.

OBJETIVES: Deficiency of 21-hydroxylase is the most common form of congenital adrenal hyperplasia (CAH-21OH). The aim of this study was to determine, by allele-specific PCR, the frequency of microconversions of the CYP21A2, in sixteen patients with the classical forms and in 5 patients with the nonclassical (NC) form of CAH-21OH and correlate genotype with phenotype. METHODS: Genotypes were classified into 3 mutation groups (A, B and C), based on the degree of enzymatic activity. Screening for 7 microconversions by allele-specific PCR diagnosed 74.3% (n=26) of the 35 unrelated alleles. RESULTS: The most frequent mutations were Q318X (25.7%), V281L (17.1%), I2 Splice (14.3%), I172N (14.3%), and R356W (14.3%). Genotype was identified in 57.1% of the patients. We observed correlation between genotype and phenotype in 91.7% of the cases. CONCLUSION: The highest frequency for Q318X (25.7%) when compared to other studies may reflect individual sample variations in this Northeastern population.

CONTEXT: Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH) because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT: We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH), luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.
