Summary:Cases of a ten-year-old boy with childhood cerebral adrenoleukodystrophy (ALD) and a 22-year-old youngster with adrenomyeloneuropathy (AMN) are reported. ALD is an inherited, X-linked perixisomal disorder associated with the accumulation of very long chain fatty acids (VLCFA). Neurological symptoms occur due to progressive demyelination and destruction of cerebral white matter and primary adrenal insufficiency. The boy with ALD manifested neurological signs (impaired spatial orientation, visual disturbances, poor handwriting, seizures). Latent primary adrenal insufficiency was established, and successfully treated by gluco- and mineralocorticoids. Lorenzo's oil (mixture of glyceroltrioleate:glyceroltrierucate 4:1) treatment significantly reduced elevated concentrations of VLCFA, but in spite of that, neurological symptoms progressed and the boy died a year after the initial clinical presentation of the disease. The boy with AMN revealed primary adrenal insufficiency at the age of 15 years. AMN was suspected when hair and eyebrows loss occurred and the diagnosis was established due to elevated VLCFA levels in the serum at the age of 22 years. On examination no neurologic signs of the disease could be detected. Adrenal insufficiency is well controlled by gluco- and mineralocorticoids. In addition to the previously described two women who were symptomatic heterozygotes we now also report on two patients with ALD and AMN. The patients reported are the first four with this peroxisomal disorder described in Croatia so far. Probably a great number of such patients remains unrecognised. Therefore, it is necessary to measure the serum VLCFA levels in males with primary adrenal insufficiency, and in those with signs of progressive central demyelination and destruction of cerebral white matter accompanied by neurological symptoms of unknown etiology.
