Abstract
Up to 40% of boys with adrenoleukodystrophy develop a severe central nervous system demyelinating form (cALD) characterized by white matter changes and gadolinium enhancement on magnetic resonance imaging (MRI). Hematopoietic cell transplant (HCT) is the only proven means to attenuate cALD progression. The elimination of active neuroinflammation is indicated radiographically by the resolution of gadolinium (Gd) enhancement and correlates to speed of donor neutrophil recovery. We analyzed 66 boys with cALD undergoing HCT for biomarkers correlating with early (30 days post-HCT) Gd signal resolution. We found that log Gd volume (cm3) on pre-HCT MRI strongly positively correlated to day 30 Gd resolution (P = .0003) with smaller volume correlating to higher proportion resolved, as was the baseline gadolinium intensity score (P = .04), plasma chitotriosidase activity (P = .04), and faster absolute neutrophil count recovery (P = .03). In multivariate analysis, log Gd volume remained superior in determining which patients would have Gd signal resolution by 30 days post-HCT (P = .016). A final analysis indicated that early Gd resolution also correlated with less neurologic progression from baseline to 1 year following HCT (P = .006). MRI Gd volume may serve as a contributing biomarker to better delineate outcomes and an important metric in comparing therapies in the treatment of cALD.

Abstract
X-adrenoleukodystrophy (X-ALD) is a metabolic, peroxisomal disease affecting the nervous system, adrenal cortex and testis resulting from inactivating mutations in ABCD1 gene which encodes a peroxisomal membrane half-adenosine triphosphate (ATP)-binding cassette transporter, ABCD1 (or ALDP), whose defect is associated with impaired peroxisomal beta-oxidation and accumulation of saturated very long-chain fatty acids (VLCFA) in tissues and body fluids. Several phenotypes are recognized in male patients including cerebral ALD in childhood, adolescence or adulthood, adrenomyeloneuropathy (AMN), Addison's disease and, eventually, gonadal insufficiency. Female carriers might present with mild to severe myeloneuropathy that resembles AMN. There is a lack of phenotype-genotype correlations, as the same ABCD1 gene mutation may be associated with different phenotypes in the same family, suggesting that genetic, epigenetic, environmental and stochastic factors are probably contributory to the development and course of the disease. Degenerative changes, like those seen in pure AMN without cerebral demyelination, are characterized by loss of axons and secondary myelin in the long tracts of the spinal cord, possibly related to the impaired lipid metabolism of VLCFAs and the associated alterations (ie, oxidative damage). Similar lesions are encountered following inactivation of ABCD1 in mice (ABCD1(-)). A different and more aggressive phenotype is secondary to cerebral demyelination, very often accompanied by inflammatory changes in the white matter of the brain and associated with activation of T lymphocytes, CD1 presentation and increased levels of cytokines, gamma-interferon, interleukin (IL)-1alpha, IL-2 and IL-6, Granulocyte macrophage colony-stimulating factor (GM-CSF), tumor necrosis factor-alpha, chemokines and chemokine receptors.

Abstract
The status of blood-brain barrier (BBB) permeability was investigated in the twitcher, an authentic murine model of globoid cell leukodystrophy (GLD, Krabbe disease) and cuprizone-intoxicated mice. Although extensive demyelination was noted in the CNS of both mice and additionally, macrophage infiltration was pronounced in the twitcher, BBB remained intact to horseradish peroxidase. Thus, the change of microenvironment caused by demyelination is not necessarily a responsible factor for increased BBB permeability in the inflammatory demyelinating conditions.

Abstract
Adrenoleukodystrophy (ALD) is an inheritable clinical disorder in which very long chain fatty acids accumulate in several tissue types. ALD is underrepresented in the psychiatric literature, although the disorder may cause an organic brain syndrome, often misdiagnosed as another psychiatric problem. A survey of 109 reported cases of ALD revealed that 39% presented with some psychiatric sign or symptom, whereas 17% presented exclusively as a psychiatric problem. A computed axial tomogram (CAT) head scan is recommended to rule out ALD in psychiatric patients suspected of having organic brain disease, as a characteristic image may be found in ALD patients who have brain involvement.

Abstract
We report on two clinically, neurologically normal relatives of a boy affected by adrenoleukodystrophy (ALD); they were found repeatedly to have the biochemical defect of an ALD hemizygote. The assay consisted in the determination of very-long-chain fatty acids in lyophilized and reconstituted plasma. While no evidence of neurologic disease (leukodystrophy or myeloneuropathy) was present in these hemizygotes, adrenocortical insufficiency provoking compensatory high ACTH release was found in both. These findings should be taken into consideration when counseling families in which cases with clinically expressed ALD are represented in several generations.

Abstract
This review represents an examination of four groups of neurodegenerative diseases, namely the sphingolipidoses, the adrenoleukodystrophy complex, the neuronal ceroid lipofuscinoses, and the sialidoses/sialuria complex. Using a combination of clinical assessment, neuroradiologic appearance, and clinical neurophysiology, one may develop strategies that lead to specific chemical or biochemical determinations for specific diagnoses. In general, disorders of white matter may be distinguished from disorders of gray matter by their appearance on computed tomography and by abnormalities of nerve conduction velocities and auditory brain stem responses. In contrast, disorders of gray matter may be distinguished from disorders of white matter by their appearance on computed tomography and utilization of electroretinography, visual evoked responses, and, to a lesser extent, EEG findings. Where necessary, skin, conjunctival, or nerve biopsy may prove to be useful adjuncts to the diagnosis. Presently, treatment depends on prevention, although aggressive efforts are under way to establish corrective therapy by enzyme replacement. To this end, the use of already existing animal models may prove to be helpful.

Abstract
Fatty acids of plasma and erythrocyte membrane sphingomyelin were determined by gas chromatography-mass spectrometry in adrenoleukodystrophy (ALD) without adrenal insufficiency. Mass chromatogram tracing with the ion at m/z 143 [(CH2)6COOH3]+ showed increases of saturated very long chain fatty acids in plasma and erythrocyte membrane sphingomyelin in ALD. The C26:0/C22:0 ratios in plasma were 0.121, 0.057 and 0.007 in cases 1 and 2, and a control subject, respectively. The C26:0/C22:0 ratios in erythrocyte membrane sphingomyelin were 0.386, 0.211 and 0.093 in cases 1 and 2 and the control subject, respectively. The demyelinating process of ALD was clearly observed in both the inversion recovery 2100/500 and spin echo 2100/80 scans on magnetic resonance imaging. The magnetic resonance image in case 1 revealed widespread demyelinated lesions, involving almost the entire cerebrum and cerebellum, at 4 years after the onset, while that in case 2 revealed demyelinated lesions mainly limited to parieto-occipital areas at 1 year after the onset.

Abstract
Inborn errors of metabolism in 40 children have been investigated by computed tomography to obtain data on the degree of cerebral involvement in neurodegenerative and storage disorders: 20 children had various mucopolysaccharidoses, 8 sphingolipidoses , 3 mucolipidoses, 2 oligosaccharidoses , 3 ceroidlipofuscinoses and 4 had various leucodystrophies . Diagnosis in all patients except Alexander's disease was established by biochemical or histological means. The main findings on CT were cerebral atrophy with enlargement of the ventricles and the subarachnoid spaces and hypodensity of the white matter. The degree of cerebral atrophy seemed to develop according to the age of the patients, as could be seen from the patients with mucopolysaccharidosis III, metachromatic leucodystrophy and GM1-gangliosidosis. Hypodensity of the white matter was found in mucopolysaccharidosis I-H, II-B, VI, in mucolipidosis II and in patients with leucodystrophies . On the other hand, there was great variability in these CT findings even in siblings, as seen in four patients with mucopolysaccharidosis VI. Among the series there were several patients who did not show any abnormalities in CT, so that a negative CT did not exclude these disorders, even the leucodystrophies . CT features such as cerebral atrophy or hypodensity were helpful in the evaluation of these disorders, though a diagnosis could not be made by CT alone.

Abstract
The CT appearance of adrenoleukodystrophy is discussed on the basis of 16 personal observations and a review of the literature. CT appearance was typical in 10 of the 16 cases, atypical but suggestive of adrenoleukodystrophy in four cases, and misleading in two cases. Atypical CT presentations were most often observed at an early phase of the disease and included unilateral lesions or lesions without opacification at the periphery of the edemalike areas after contrast enhancement. In three cases, neurological signs, CT scans, and conjunctival and skin biopsies were highly suggestive of adrenoleukodystrophy, but there was no adrenal insufficiency. These cases may correspond to an evolutive or phenotypic variant of adrenoleukodystrophy.

Abstract
Adrenomyeloneuropathy (AMN) is reported in two kindreds. In the first family, four male patients were affected: two adults with the full clinical picture but with a different chronology of the main symptoms, a third adult with central nervous system involvement and a child who died early with adrenal insufficiency. The second family included two male patients with AMN, one adult with raised ACTH levels and his nephew with normal adrenal function. Two other young males died with adrenoleukodystrophy (ALD), one being subjected to a postmortem study. Clinical, endocrinological, neurophysiological and pathological studies were performed. The following conclusions can be made (1) AMN and ALD are closely related entities; (2) there exists a considerable intrafamilial variability of the clinical picture; (3) AMN is to be included in the differential diagnosis of myelopathies and, conversely, signs of central nervous system damage must be sought in males patients with adrenal insufficiency; (4) electron microscopy of nerve twigs brings supportive diagnostic evidence pending the more widespread determination of the C26/C22 fatty acids ratios in cultured fibroblasts or plasma.

Abstract
Because postmortem brain and adrenal tissue from patients with adrenoleukodystrophy (ALD) or adrenomyeloneuropathy (AMN) have been shown to contain abnormally large amounts of very long chain fatty acids (C24 through C30), we searched for such an abnormality in cultured skin fibroblasts. Total lipid extracts of cultured fibroblasts were hydrolyzed, their fatty acid composition was determined by gas-liquid chromatography, and the ratio of C26 to C22 fatty acids was calculated. In 29 control cell lines this ratio was 0.064 +/- 0.019. In 5 patients with autopsy-proved ALD the ratio was 0.778 +/- 0.139; in 6 patients with clinical features typical of ALD it was 0.764 +/- 0.092; in 2 patients with autopsy-proved AMN, 0.890 +/- 0.02; and in 2 patients with clinical features typical of AMN, 0.560 +/- 0.079. Abnormal ratios were observed in 4 of 5 ALD heterozygotes. In 3 patients in whom the diagnosis of ALD was suspected, an abnormal ratio (0.860) was observed in 1 and normal ratios (0.06 and 0.074) in the 2 others.

Abstract
Adrenoleukodystrophy is not usually considered in the differential diagnosis of the infantile onset of failure to thrive with motor and intellectual retardation. Rather, symptoms have started in childhood and have progressed over some years; not all patients have had overt adrenocortical insufficiency. The two brothers reported here developed symptoms in the neonatal period. In each the nature of the primary cerebral disorder was not recognized, because other etiologic factors clouded the diagnostic studies. In the younger brother, Case 1, a high titer (1:256) for cytomegalovirus (CMV) led to the suspicion that CMV infection accounted for the neurologic and ophthalmologic findings. Progressive neurologic deterioration at the age of 6 years prompted brain biopsy to confirm the diagnosis of progressive CMV encephalitis. In the older brother, Case 2, hemogenic hydrocephalus due to traumatic birth injury was held responsible for the psychomotor retardation and cerebral palsy. At necropsy, the adrenal glands in both cases were severly atrophic. In Case 1, a markedly inflammatory leukodystrophic process affected chiefly the frontal centra semiovalia and internal capsules, with relative sparing of parieto-occipital white matter and subcortical U-fibers. Heavy lymphocyte and monocyte cuffs surrounded many blood vessels in the white matter, and oil-red-O and PAS-positive macrophages were scattered in the zones of myelin disintegration and loss. Focally, the leukodystrophic process was so intense that cavitation necrosis was present, especially in the internal capsules. Further, PAS-positive, striated macrophages were aggregated in large clusters in liver, spleen, and lymph nodes. At the ultrastructural level, linear and gently arced, parallel, coapted or widely separated leaflets measuring 3-4 nm in width were identified in macrophages of the brain biopsy and in autopsy liver and lymph node. Biochemical analysis of fresh, frozen autopsy brain demonstrated cholesterol esters with long-chain fatty acids by thin-layer and gas-liquid chromatography. In Case 2, the leukodystrophic process could be readily identified in the brainstem and cerebellum but was masked in the cerebral hemispheres by the extensive hydrocephalus. The adrenal glands were atrophic and at light microscopy revealed adenomatoid nodules, many ballooned coritcal cells and very rare cells with striated cytoplasm. Masses of PAS-positive macrophages were encountered in liver and lymph nodes. In both cases, only old Wallerian degeneration of the corticospinal tracts was found in the spinal cord.

Abstract
A young male patient with adrenoleukodystrophy progressed from the frontal to the parieto-occipital region was reported. The spreading pattern of the brain lesion in this patient was confirmed by a serial examination of Technetium scintigrams and the neuropathological findings. The high uptake area of the isotope in the scintigrams seemed to represent the active demyelinating and infiltrative-reactive process in the white matter. A chemical analysis of the frozen white matter tissue of the patient revealed the existence of long chain fatty acids mor than C 22 in cholesteryl esters and gangliosides. It is suggested by this case that the demyelination process can start in the frontal white matter also in adrenoleukodystrophy as well as in Schilder's disease.

Abstract
Clinical, laboratory, and electrophysiological data, including brainstem auditory evoked responses, are reported in a case of adrenoleukodystrophy. A striking asymmetry was noted in wave VI of the brainstem auditory evoked potential, followed by absence of any recognizable wave on the abnormal side. The presumed site of origin of wave VI is the medical geniculate body, a structure severely involved in adrenoleukodystrophy. It is suggested that the brainstem auditory evoked response may promise noninvasive diagnostic aid in this disorder and that absence of wave VI may emerge as a clinically useful finding in diseases of the central nervous system.

Abstract
The case of a 14-year-old boy with "diffuse cerebral sclerosis", preceded by signs of primary adrenal cortical insufficiency for 7 years with familiar antecedents is reported. This disorder, named adrenoleukodystrophy, has a sex-lin(ed recessive inheritance. The clinical picture is characterized by mental deterioration, gait disturbances, visual impairment, associated with primary adrenal cortical insufficiency. Confirming the data from literature, in our case the pathological study showed myelin degeneration and diffuse gliosis in the cerebral white matter, with no involvement of subcortical fibers. Inflammatory cells are common, and have a perivascular distribution. In the fasciculata and reticular zones of the adrenal gland, "baloon-shaped" cells are evident, most of them presenting a vacuolized and striated cytoplasm. Similar lipidic inclusions have been found in the Schwann cells of the periheral nerves and testis. The findings are compared with twenty cases from the literature.

Abstract
Analysis of computed tomograms of patients with adrenoleukodystrophy in the early disease phase reveals a dinstinct CT apperance. It is suggested that brain or adrenal biopsy may not be necessary for diagnosis of adrenoleukodystrophy when these particular CT features are correlated with the clinical course and other laboratory parameters.

Abstract
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.
