Summary

We describe a case of a 40-year-old woman who was admitted to the intensive care unit with a rapid onset of dyspnea and orthopnea. She presented progressive weakness, weight loss and secondary amenorrhea during last year, while intermittent fever was present for the last two months. Initial biochemical evaluation showed anemia, hyponatremia and increased C-reactive protein levels. Clinical and echocardiographic evaluation revealed cardiac tamponade, which was treated with pericardiocentesis. Pleural fluid samples were negative for malignancy, tuberculosis or bacterial infection. Hormonal and serologic evaluation led to the diagnosis of autoimmune polyglandular syndrome (APS) type 2 (including primary adrenal insufficiency and autoimmune thyroiditis), possibly coexisting with systemic lupus erythematosus. After symptomatic rheumatologic treatment followed by replacement therapy with hydrocortisone and fludrocortisone, the patient fully recovered. In patients with the combination of polyserositis, cardiac tamponade and persistent hyponatremia, possible coexistence of rheumatologic and autoimmune endocrine disease, mainly adrenal insufficiency, should be considered. Early diagnosis and non-invasive treatment can be life-saving.

Learning points:

  • In patients with the combination of polyserositis, cardiac tamponade and persistent hyponatremia, possible coexistence of rheumatologic and autoimmune endocrine disease, mainly adrenal insufficiency, should be considered.
  • Early diagnosis and non-invasive treatment can be life-saving for these patients.
  • Primary adrenal insufficiency requires lifelong replacement therapy with oral administration of 15–25 mg hydrocortisone in split doses and 50–200 µg fludrocortisone once daily.

Summary

11β-hydroxylase deficiency (11β-OHD), an autosomal recessive inherited disorder, accounts for 5–8% of congenital adrenal hyperplasia. In Greece, no cases of 11β-OHD have been described so far. The patient presented at the age of 13 months with mild virilization of external genitalia and pubic hair development since the age of 3 months. Hormonal profile showed elevated 11-deoxycortisol, adrenal androgens and ACTH levels. ACTH stimulation test was compatible with 11β-OHD. DNA of the proband and her parents was isolated and genotyped for CYP11B1 gene coding cytochrome P450c11. The girl was found to be compound heterozygous for two CYP11B1 novel mutations, p.Ala386Glu (exon 7), inherited from the father and p.Leu471Argin (exon 9) from the mother. Hydrocortisone supplementation therapy was initiated. Four years after presentation she remains normotensive, her growth pattern is normal and the bone age remains advanced despite adequate suppression of adrenal androgens.

Learning points

  • 11β-hydroxylase (CYP11B1) deficiency (11OHD; OMIM +202010) is the second most common cause of CAH accounting for approximately 5–8% of cases with an incidence of 1:100 000–1:200 000 live births in non-consanguineous populations.
  • Two CYP11B1 inactivating novel mutations, p.Ala386Glu and p.Leu471Arg are reported
  • Regarding newborn females, in utero androgen excess results in ambiguous genitalia, whereas in the male newborn diagnosis may go undetected. In infancy and childhood adrenal androgen overproduction results in peripheral precocious puberty in boys and various degrees of virilization in girls.
  • Accumulation of 11-deoxycorticosterone and its metabolites causes hypertension in about two thirds of patients.
  • Diagnosis lies upon elevated 11-deoxycortisol and DOC plus upstream precursors, such as 17α-hydroxyprogesterone and Δ4-androstenedione.
  • The established treatment of steroid 11β-OHD is similar to that of steroid 21-hydroxylase deficiency and consists of glucocorticoid administration in order to reduce ACTH-driven DOC overproduction resulting in hypertension remission and improvement of the virilization symptoms.
