In a 16-member black kindred with Fabry's disease, four hemizygous males had plasma alpha-galactosidase levels less than 6% and seven heterozygous females had plasma alpha-galactosidase levels between 10% and 50% of normal. A 16-year-old index male had hypertension with left ventricular hypertrophy, abnormal renal function, tortuous retinal veins, "myelin" inclusions in bone marrow macrophages, and intraepithelial inclusion bodies in the kidney. Scrotal angiectasia developed a year after diagnosis. The three other affected males had left ventricular hypertrophy and retinal vein tortuosity. Of the seven carrier females, five had frequent headaches, four had retinal vessel changes, three had proteinuria with normal renal function, and two had bundle-branch blocks on ECGs. There was no deuteranomalopia in this family, although the inheritance pattern of the Fabry gene is X-linked recessive.

This report concerns an 18-year-old boy who is hemizygote for Fabry's disease. Varying degrees of nonpulsating headache crises, lasting from a few hours to several days, began when he was 16 years of age. Painful crises in the extremities, characteristic of Fabry's disease, were not present. Although only occasional, he had several episodes of throbbing headache with vomiting without aura. The meningeal signs were equivocal, although the patient had noninfectious pleocytosis, intracranial hypertension, delayed radioisotope clearance on cisternography, and multiple old cerebral infarcts. Nonsteroidal anti-inflammatory drugs, antidepressants, carbamazepine, and glycerol were of no benefit for his headache. Although its mode of action remains obscure, prednisolone was effective for treating the headache and the aseptic meningeal reaction.

Fabry's disease (FD) is a rare, sex-linked disorder resulting from alpha-galactosidase deficiency. Cerebrovascular complications have been reported in the literature but have not been systematically analyzed. We report 2 patients and review 51 previously reported cases (descriptive meta-analysis) to clarify the clinical, radiologic, and pathologic features. The average age at onset of cerebrovascular symptoms was 33.8 years for hemizygous individuals (n = 43) and 40.3 years of heterozygotes (n = 10). The most frequent symptoms and signs were as follows (in descending order of frequency): hemiparesis, vertigo/dizziness, diplopia, dysarthria, nystagmus, nausea/vomiting, head pain, hemiataxia, and ataxia of gait, in the hemizygote group; and memory loss, dizziness, ataxia, hemiparesis, loss of consciousness and hemisensory symptoms, in the heterozygote group. The vertebrobasilar circulation was symptomatic in 67% of the hemizygotes and 60% of the heterozygotes. Intracerebral hemorrhage was found in 4 patients (3 hemizygotes and 1 heterozygote). Elongated, ectatic, tortuous vertebral and basilar arteries were the most common angiographic and pathologic features. For the hemizygotes, the recurrence rate for cerebrovascular disease was 76% and the death rate was 55%; 86% of the heterozygotes had recurrent cerebrovascular event(s) and 40% died. The cerebrovascular manifestations of FD, in both hemizygotes and heterozygotes, are predominantly due to dilative arteriopathy of the vertebrobasilar circulation, frequently recur, and portend a poor prognosis.

Fabry's disease is a rare, X-linked disorder of the glycosphingolipid metabolism, in which a partial or total deficiency of a lysosomal alpha(alpha)-galactosidase results in the progressive accumulation of neutral glycosphingolipids with terminal alpha galactose moieties (i.e., cerebroside di- and trihexoside) in most body fluids and tissues. Accumulation of neutral glycosphingolipids occurs within the lysosomes of endothelial, perithelial, and smooth muscle cells of the myocardial and renal systems; to a lesser extent in reticuloendothelial and connective cells of the cornea; and in ganglion and perineural cells of the autonomic nervous system. In Korea, 7 cases of Fabry's disease have been reported. A 29-year-old man with fever and headache had typical skin findings and a family history of Fabry's disease, and it was confirmed through renal biopsy and enzyme assay for alpha-galactosidase. We report a case of Fabry's disease with a review of the literatures reported in Korea.

We describe a man and a woman with Fabry's disease. Renal biopsies showed late and early stages respectively of focal and segmental glomerulosclerosis (FSGS) and vascular changes. Clinically the hemizygous patient had advanced renal disease with nephrotic range proteinuria and serum creatinine 122 micromol/l. The female carrier had minimal albuminuria, borderline GFR with a normal serum creatinine, acroparesthesias, moderate fatigue, tinnitus and headache accompanied by ischemic cerebral lesions. Enzyme replacement therapy (ERT) was initiated according to our Fabry protocol, partly due to the renal morphologic findings. We conclude that FSGS and vascular changes may be an early morphologic finding in Fabry's disease, even in patients with subtle albuminuria. The potential role of FSGS as a marker of progressive renal disease in some Fabry patients is discussed. As FSGS and vascular changes obviously may exist across a wide range of clinical presentations and have potential prognostic implications, we suggest that a renal biopsy should be performed prior to enzyme replacement therapy in all adult Fabry patients with proteinuria of various levels. Efforts should be made to develop a scoring system to evaluate potential histologic markers. Protocol biopsies may have therapeutic implications and may provide valuable information in the evaluation of start and dosing of ERT.

Fabry Disease (FD) is an X-linked lysosomal storage disorder (prevalence about 1 : 100 000) caused by a genetic defect associated with a lack of alpha-galactosidase A (alpha-GAL) enzyme activity. As a consequence, neutral glycosphingolipides can not be cleaved and metabolized, and accumulate in lysosomes of several tissues, particularly in vascular endothelium and smooth muscle cells. The most prominent symptoms comprise pain attacks and acroparesthesia, angiokeratoma, corneal opacity, renal and cardiac dysfunction, hypo- and anhidrosis, gastrointestinal symptoms, and cerebrovascular dysfunction with vertigo, headache, and cerebral ischemia. Characteristic symptoms of FD can occur in male and female patients with the same prevalence, while females with FD seem to be less severely affected. The course of untreated illness is progressive with considerable interindividual variability. Since 2001 two enzyme replacement therapies are approved which can possibly stop the disease progress and alleviate symptoms. The very few reports and clinical observations have shown that a very high proportion of FD patients develop neuropsychiatric symptoms. However, accurate data are lacking. Although the pathophysiologic mechanisms are quite unknown, it is surmised that sphingolipid deposits in the endothelium of small cerebral vessels lead to regional cerebral ischemia accompanied by neuropsychiatric symptoms and deficits. Furthermore, patients with FD are chronically distressed by pain attacks and additional somatic and psychological impairment. Frequently, pain attacks are triggered by psychosocial stress. The high interindividual variability can, thus, also be interpreted on the basis of existing stress and coping models. The present paper will review the presently available psychiatric and neuropsychological findings in FD and will discuss difficulties associated with classification and differential diagnosis of psychiatric disorders occurring in patients with FD.

A 38-year-old male Caucasian with Fabry disease presented with angiokeratomas and tortuous conjunctival and retinal vessels. Additionally, the patient showed characteristic skin lesions of psoriasis and seborrheic dermatitis. His past medical history revealed anhidrosis, acral paresthesias, myocardial infarction, phlebothrombosis, hypertension, antithrombin III deficiency, factor V Leiden disease, chronic obstructive lung disease, tinnitus, diarrhea, recurrent abdominal pain, headache, and depressive mood. He was treated with intravenous substitution of the deficient enzyme alpha-galactosidase A. Possible future options in treatment of Fabry disease are discussed.

Several hereditary disorders induce angiopathy in the intracranial cerebrovasculature and thus cause ischemic strokes. MELAS is a maternally inherited mitochondrial disorder that produces stroke-like events. Sickle cell disease, which is the result of a single base pair substitution, is a major cause of strokes in children. Homocystinuria, an autosomal recessive syndrome, produces premature atherosclerosis. Hereditary cerebroretinal vasculopathy is an autosomal dominant disorder that causes retinal and brain infarctions. Fabry disease is an x-linked disorder that can cause stroke in adults. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy is an autosomal dominant syndrome that is associated with ischemic stroke and migraine-like headaches. The clinical presentation, stroke pathophysiology, and gene defects associated with these heritable disorders are reviewed.

We present outcomes of 54 months' agalsidase beta enzyme replacement therapy of two 48- and 46-year-old brothers with Fabry disease. The diagnosis was confirmed in 1997, and at that moment serious damage of internal organs was observed. During enzyme replacement therapy in both brothers the following changes were observed: amelioration of gastrointestinal symptoms, gain of body weight and reduction of cardiac hypertrophy in ECG. In older brother we observed: improvement in coronary blood flow, absence of angina pectoris, dyspnea, partial remission of headache and acroparaesthesia. Reduction of proteinuria, stabilization of creatinine clearance and appearance of perspiration were also noticed. In a younger brother, with a milder form of disease, we observed: improvement of hearing and vertigo, headache reduction, as well as stabilization of kidney function (although proteinuria was slightly increased). Unfortunately, acroparaesthesia and muscle pains in the legs became more severe. Enzyme replacement therapy in Fabry disease, even started in late adulthood, is effective by stabilizing organ function and markedly improving of quality of life.

Anderson-Fabry disease (AFD) is an X-linked recessive lysosomal disease caused by alpha-galactosidase A (alpha-gal) deficiency, causing progressive glycosphingolipid storage in various organ systems. Headache is a frequent symptom. Cerebral magnetic resonance imaging (MRI) often shows multiple white matter lesions (WML), like those seen in patients affected by migraine, in particular with aura (MA). To our knowledge, there are no reports about the prevalence of AFD in patients with MA. The objective of the study was to determine AFD prevalence, as assessed by alpha-gal activity and genetic tests, in MA patients. We evaluated 73 consecutive patients followed by the Headache Centre of our Department with a diagnosis of MA. They were screened for migraine characteristics and cerebrovascular risk factors. Gaseous contrast transcranial Doppler was used to diagnose right-to-left shunt and MRI to detect WML. All patients underwent blood test to evaluate peripheral alpha-gal activity and to identify alpha-gal gene mutations. Of 73 consecutive screened subjects (59 females, 14 males; mean age 38.3 +/- 11.8 years), the known GLA pathologic mutation p.[Asp313Tyr] was found in a 38-year-old woman, with a history of MA, deep venous thrombosis and abdominal pain. Cerebral MRI showed small WML. This is the first study reporting AFD prevalence in a cohort of MA patients. We found a relatively high prevalence (about 1.37%) among the examined patients, even if this finding needs to be confirmed in a larger sample. Despite this high prevalence, it seems not necessary to screen systematically all MA patients for AFD, but since it is a treatable genetic disorder, it is worthwhile to consider it for the subgroup of patients presenting WML and other typical AFD symptoms.
