Two male infants with hyperpigmentation, vomiting, lethargy and weight loss were reported. Hypoglycemia, hyponatremia, hypochloremia, hyperkalemia and metabolic acidosis were suggestive diagnosis of salt losing adrenocortical insufficiency. The absence of ambiguous genitalia, low 24 hour urinary 17 KS and pregnanetriol excretion precluded congenital adrenal hyperplasia. Low basal levels of plasma aldosterone and cortisol and low 24 hour urinary 17 OHCS excretion with disability to increase their corticosteroid secretions after ACTH stimulation as well as furosemide and theophylline infusions were supportive for the diagnosis of congenital adrenal hypoplasia. The definitive diagnosis was confirmed by ultrasonogram and computerized tomography. Family histories suggested X-linked recessive inheritance in these reported cases. Evidence of progressive postnatal adrenocortical degeneration was documented by progressive deterioration of adrenocortical functions beginning from mineralocorticoid to total corticosteroid deficiencies. The increased brain serotonin synthesis as the associated pathology of X-linked congenital adrenal hypoplasia was proposed on the basis of elevated basal plasma GH and PRL levels in the reported cases, taken together with an incidence of congenital LH deficiency and persistent ACTH hypersecretion in corticosteroid treated patients reported elsewhere.

Congenital Adrenal Hyperplasia (C.A.H.) is an autosomal recessive disorder which is often life threatening during the neonatal period prior to establishment of the diagnosis and instigation of appropriate treatment. In females the condition is usually detected at birth due to genital ambiguity. Unfortunately males or extremely virilized females often remain undetected until they suffer a potentially fatal adrenal crisis. Typically, a crisis occurs within the first couple of weeks of life and is preceded by a history of failure to thrive, lethargy and vomiting which may be misdiagnosed as resulting from pyloric stenosis. Vascular collapse and diminished consciousness ensue if adrenal insufficiency remains undetected. Initial biochemical investigation of the shocked neonate with C.A.H. reveals severe hyperkalaemia and hyponatraemia, which initially may be thought to be due to renal failure. Hypoglycaemia may also be a feature. Initial resuscitation requires intravenous saline and hydrocortisone. Once physiologically stable, oral steroids are used to replace absent glucocorticoids and mineralocorticoids. The psychosocial impact of having a critically ill baby, with a relatively uncommon genetic disorder, who requires lifelong treatment can be overwhelming for parents. There is an ongoing risk of adrenal crisis throughout the child's life during periods of physiological stress. Parents require education on the management of medication during normal childhood illnesses; the early indicators of crisis and instruction in injection technique. In addition to skilled technical nursing interventions for their baby, parents can benefit from accurate information and contact with the C.A.H. support group.

Lipoid congenital adrenal hyperplasia (lipoid CAH), a rare disorder of steroid biosynthesis, is the most severe form of CAH. In this disorder the synthesis of glucocorticoids, mineralocorticoids and sex steroids is impaired which result in adrenal failure, severe salt wasting crisis and hyperpigmentation in phenotypical female infants irrespective of genetic sex. In this report, we presented a 28-day-old phenotypic female infant, which referred with lethargy, failure to thrive and electrolyte abnormalities. Considering the clinical and biochemical findings, lipoid CAH was diagnosed and replacement therapy with standard doses of glucocorticoid and mineralocorticoid and sodium chloride was initiated. During follow-up, she had good clinical condition, but at 6 years of age, she refers with hypertension and adrenal insufficiency because of arbitrary drug discontinuation by mother. In ultrasonography an abdominal mass (the testicles) was reported. Chromosome study showed 46XY pattern. Orchiectomy was performed. We recommended that in cases with clinical presentation of adrenal insufficiency if there is not the facility to determine the karyotype, repeated ultrasonography perform during follow-up. In addition, investigating the genetic bases of the disorder would help us to determine the pathogenesis of lipoid CAH in our community. It would be helpful in prenatal diagnosis and treatment of the disorder to prevent its related comorbidities.

Congenital adrenal hyperplasia is a genetic endocrinologic disorder. The severe classic form occurs in one in 15,000 births worldwide. Twenty-one-hydroxylase deficiency (21-OHD) is the most common cause in this autosomal recessive disease. It can cause virilization, ambiguous genitalia at birth and severe life threatening condition due to salt wasting. In this report we describe the clinical course of a male neonate presenting with lethargy, failure to thrive (FTT), genital pigmentation, electrolytes imbalance and high serum 17-hydroxy-progesterone (17-OHP) level and subsequently diagnosed as Congenital Adrenal Hyperplasia. After the initial crises management, the child was continued on replacement therapy. During the follow up, he was found to grow appropriately and achieving normal milestones for age.

We report a case of a 10-day-old male infant who presented to the emergency department with severe electrolyte imbalance and life-threatening arrhythmia. The parents reported a 3-day history of poor feeding and lethargy. On examination, he was bradycardic (heart rate of 65 beats/min) with signs of dehydration. His ECG showed broad complex bradycardia. Blood gas showed metabolic acidosis with hyponatraemia and hyperkalaemia. A probable diagnosis of congenital adrenal hyperplasia (CAH) with salt-wasting crisis was made and treatment was commenced. He was given saline bolus, nebulised salbutamol, calcium gluconate and hydrocortisone. Following the above interventions, his heart rate rose to 150 beats/min with a regular sinus rhythm within a period of 40 min. The diagnosis of CAH secondary to 21-hydroxylase deficiency with mutation in CYP21A2 was confirmed by genetic studies. He was discharged home with hydrocortisone, fludrocortisone and sodium chloride.
