A Case of Congenital Adrenal Hyperplasia due to 3-Beta-Hydroxysteroid Dehydrogenase Deficiency Presented With Acute Liver Failure

Congenital adrenal hyperplasia (CAH) is a group of rare autosomal disorders characterized by a variety of defects in adrenal steroidogenesis. Most cases of CAH are due to an enzyme deficiency in either 21-hydroxylase or 11-beta-hydroxylase. A much rarer form of CAH due to 3-betahydroxysteroid dehydrogenase (3B-HSD) deficiency results in impaired synthesis of all steroid hormones. The clinical presentation of undervirilization in 46 XY patients, hyponatremia, hyperkalemia, and recurrent hypoglycemia in 3B-HSD deficiency cases is well described in the literature. We describe a neonate with 3B-HSD deficiency that presented with ambiguous genitalia and hypoglycemia and was found to have comorbid coagulopathy, cholestasis, and direct hyperbilirubinemia with liver failure that resolved with glucocorticoid and mineralocorticoid treatment. Prompt recognition of this disease is imperative for timely intervention.

5-Fluorouracil Neurotoxicity in the Absence of Dihydropyrimidine Dehydrogenase Deficiency Case Report

5 fluorouracil (5-FU)-related neurotoxicity is a rare and severe complication of 5-FU administration. Dihydropyrimidine dehydrogenase (DPD) deficiency is associated with an increased risk of serious adverse reactions due to its role in 5-FU metabolism. We report a case of acute reversible neurotoxicity with global areas of diffusion restriction in a patient with colorectal adenocarcinoma being treated with leucovorin calcium, 5-fluorouracil, and oxaliplatin (FOLFOX) without DPD deficiency following uridine triacetate administration.

A rare presentation of a rare metabolic disorder – Multiple Acyl CoA dehydrogenase deficiency presenting as rhabdomyolysis and renal failure

Multiple acyl-CoA dehydrogenase deficiency (MADD) is a rare metabolic disorder of oxidation of amino acids and fatty acids with an autosomal recessive inheritance. Patients usually present symptoms of MADD in the neonatal period, though it can also be diagnosed in the late adulthood. We present a 36-year-old male with MADD who had sensory axonal neuropathy, rhabdomyolysis metabolic acidosis, lactic acidosis, hypoglycemia and low ketone bodies and renal failure. Early diagnosis and prompt management with carnitine and riboflavin supplements can help in better management of this rare metabolic disorder.
