Four cases of adrenoleukodystrophy (ALD) and one case of adrenomyeloneuropathy (AMN) have developed in a kindred over three generations demonstrating that AMN is a clinical variant of ALD. Pituitary-adrenal function studies were performed in 10 family members, including two affected males and four females identified as carriers of ALD/AMN. No pituitary-adrenal abnormality was found in the carriers. However, basal morning plasma adrenocorticotropic hormone (ACTH) levels were markedly elevated in the two males with ALD and AMN, despite the fact that they had no clinical signs of adrenal insufficiency and that morning plasma cortisol levels and their response to maximal exogenous ACTH stimulation appeared to be normal. In addition, the integrated 24-hour response to the administration were also subnormal in these two cases. Thus, people with ALD and AMN may have subclinical partial adrenocrotical insufficiency. No other endocrinologic dysfunction was identified.

The term "Schilder's disease" has been used to describe conditions as disparate as adrenoleukodystrophy, myelinoclastic diffuse sclerosis, and postinfectious and postvaccinal encephalomyelitis. The eponymic designation should be reserved for instances of myelinoclastic diffuse sclerosis that correspond to the case described by Schilder in 1912. The diagnosis cannot be made unless adrenoleukodystrophy has been ruled out by analysis of the long-chain fatty acids of plasma cholesterol esters. Schilder's myelinoclastic diffuse sclerosis, a variant of multiple sclerosis, is a very rare disease that occurs in children and adults of both sexes and appears to respond to vigorous treatment with corticosteroids and/or corticotropin. A case of this disease is reported and the recent literature of cases that have been called Schilder's disease is reviewed.

Human adrenal development is a complex and relatively poorly understood process. However, significant insight into some of the mechanisms regulating adrenal development and function is being obtained through the analysis of individuals and families with adrenal hypoplasia. Adrenal hypoplasia can occur: (1) secondary to defects in pituitary adrenocorticotropin (ACTH) synthesis, processing and release (secondary adrenal hypoplasia; e.g. HESX1, LHX4, SOX3, TPIT, pituitary POMC, PC1); (2) as part of several ACTH resistance syndromes (e.g. MC2R/ACTHR, MRAP, Alacrima, Achalasia, Addison disease), or as (3) a primary defect in the development of the adrenal gland itself (primary adrenal hypoplasia; e.g. DAX1/NR0B1 - dosage-sensitive sex reversal, adrenal hypoplasia congenita critical region on the X chromosome 1). Indeed, the X-linked form of primary adrenal hypoplasia due to deletions or mutations in the orphan nuclear receptor DAX1 occurs in around half of male infants presenting with a salt-losing adrenal crisis, where no obvious steroidogenic defect (e.g. 21-hydroxylase deficiency), metabolic abnormality (e.g. neonatal adrenoleukodystrophy) or physical cause (e.g. adrenal haemorrhage) is found. Establishing the underlying basis of adrenal failure can have important implications for investigating associated features, the likely long-term approach to treatment, and for counselling families about the risk of other children being affected.

The patient first noticed spasticity and weakness in his legs. He was diagnosed with chronic myelogenous leukemia (CML); the symptoms were attributed to neuropathy associated with CML. By treatment with dasatinib, he achieved complete hematological remission, but his difficulty in walking was not improved. His neurological symptom worsened together with an increase in body temperature and then disappeared together with a normalized body temperature, which may be attributed to the Uhthoff's phenomenon often observed in multiple sclerosis. He later developed acute fever, vomiting and a high adrenocorticotropic hormone (ACTH) level, which was diagnosed as adrenal insufficiency. Eventually, he was diagnosed with a milder form of adrenoleukodystrophy (ALD), adrenomyeloneuropathy (AMN) by increased levels of Very Long Chain Fatty Acids (VLCFAs) and genetic testing of the ATP binding cassette subfamily D member 1 (ABCD1) gene. A missense mutation (c.521A>C, p.Tyr174Ser), previously reported to induce severe cerebral ALD, was detected in exon1. Thus, clinical manifestation of ALD is determined by interaction between the primary ABCD1 mutation and modifying genetic and environmental factors. Physicians should be aware of the differing symptoms of AMN and determine the level of VLCFAs in patients having primary adrenal insufficiency, especially those complicated with neurological dysfunction. This is the first report of an AMN patient complicated with CML.

Childhood cerebral X-linked adrenoleukodystrophy (XALD) typically manifests with symptoms of adrenocortical insufficiency and a variety of neurocognitive and behavioral abnormalities. A major diagnostic clue is the characteristic neuroinflammatory parieto-occipital white matter lesions on magnetic resonance imaging. This study reports a 5-year 10-month old boy presenting with generalized skin hyperpigmentation since 3 years of age. Over the past 9 months, he had developed right-sided hemiparesis and speech and behavioral abnormalities, which had progressed over 5 months to bilateral hemiparesis. Retrospective analyses of serial brain magnetic resonance images revealed an unusual pattern of lesions involving the internal capsules, corticospinal tracts in the midbrain and brainstem, and cerebellar white matter. The clinical diagnosis of childhood cerebral adrenoleukodystrophy was confirmed by elevated basal levels of adrenocorticotropin hormone and plasma very long chain fatty acid levels. Additionally, sequencing of the ABCD1 gene revealed a novel mutation. The only specific palliative therapy that could be offered after diagnosis was dietary intervention. The patient died within 16 months of onset of neurological symptoms. Awareness that childhood cerebral XALD can present with atypical neuroimaging patterns early in its course may aid diagnosis at a stage when definitive treatment can be attempted and timely genetic counseling be offered to the family.
