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.

Two sisters, one with a long history of proteinuria and the other of hematuria, came for examination. Physical examination and routine laboratory workups did not show any significant abnormalities. The renal ultrastructural changes in case 1 showed marked enlargement and foamy vacuolation of all the glomerular capillary visceral epithelial cells, which was not found in other glomerular cells. The renal changes in case 2 showed similar lesions but with fewer cells involved and also with less severity, but the involved cells showed marked lamellation within the vacuoles. The serum alpha-galactosidase activity was 4.9 and 3.0 nmol/h/mL serum, respectively (normal values, 12.1 +/- 1.6 nmol/h/mL serum, mean +/- SD, n = 11), thus confirming the heterozygous variety of Fabry's disease. Our findings in these two cases reveal that patients with heterozygous Fabry's disease may present with renal symptoms only, which may be either proteinuria or hematuria.

A 39 year-old man was found to have mild proteinuria by urinary examination since one year ago. He was for the first time diagnosed as having Fabry's disease by histopathological and electronmicroscopic findings of the renal biopsy specimens, which showed the presence of numerous vacuolated cells and electron dense bodies inside the cells. The level of WBC alpha-galactosidase was significantly lower than normal level. The pedigree of this patient showed a familial history of various types of renal disease. One of the patient's brothers also showed decreased level of WBC alpha-galactosidase, who has been treated by maintenance hemodialysis for 2 years. It is concluded that early diagnosis of this disease through renal biopsy and WBC alpha-galactosidase level is important to manage the future course of patients with Fabry's disease.

A case of Fabry's disease in a 22-year-old male patient who had mild proteinuria and dark-red eruptions is reported. He had been treated as a case of a so-called "chronic glomerulonephritis" for one year. However, histopathological findings of the renal biopsy specimens showed the presence of numerous vacuolated cells in the glomeruli. These vacuolated cells contained numerous electron dense bodies observed by electron microscopy. Skin lesions of this patient were consistent with those of angiokeratoma corporis. The levels of serum alpha-galactosidase were significantly lower than those of healthy controls. The mother of this patient also showed decreased levels of serum alpha-galactosidase. The pedigree of this patient showed a familial history of various types of renal diseases. It was postulated that Fabry's disease occurring in older patients has a worse clinical course. it is concluded that early detection of this disease through biopsy and the assay of serum alpha-galactosidase levels is important in managing the future course of patients with Fabry's disease.

Percutaneous renal biopsy was performed in a surface coal miner with radiographic and histopathologic pulmonary changes consistent with acute silicolipoproteinosis who developed proteinuria and hematuria. Electron microscopic evaluation of the renal tissue specimen revealed a diffusely thickened glomerular basement membrane, foot process effacement, and dense lamellar inclusions in swollen glomerular epithelial cells, similar to those seen in Fabry's disease. However, normal levels of plasma alpha-galactosidase A, normal urinary sediment glycosphingolipids and the absence of the clinical characteristics of Fabry's disease excluded this diagnosis. This case illustrates that electron-dense lamellar inclusions, similar to those seen in Fabry's disease, may be seen in other entities such as nephropathy associated with silicosis.

Fabry's disease is a rare familial disorder of glycolipid metabolism which is caused by a deficiency of a lysosomal enzyme alpha-galactosidase. A Finnish family is described in which cornea verticillata was found in the father and 2 daughters. In all cases, there were symptoms suggesting Fabry's disease: febrile episodes the origin of which was not clear, limb pains and, in the case of the father, 20 years of proteinuria with elevated ESR, and hemiplegia and aphasia following a cerebral thrombosis at the age of 43. The diagnosis was confirmed by demonstration of an alpha-galactosidase deficit in the serum and urine of all patients. Deficiency of this enzyme leads to abnormally high urinary tri- and dihexosyl ceramide levels, and this was observed in the father and the elder daughter. At the age of 12, the daughter had loss of vision in her right eye as a result of occlusion of the central retinal artery. Electron microscopic (EM) examination of the father's dermal angioma suggested Fabry's disease. Computerized cranial tomography of the father revealed not only the cerebrovascular condition but also a disease affecting the white matter of the brain.

We assayed plasma activities of beta-galactosidase, beta-hexosaminidase, alpha-fucosidase and alpha-galactosidase involved in degradation of the glycoprotein molecule in 110 insulin-dependent diabetics aged 3-1/2 to 19 years and compared them to a group of normal youngsters. We correlated the plasma enzyme activities with the duration, control and sequelae of insulin-dependent diabetes. Insulin-dependent diabetics had a significantly higher plasma activity of beta-hexosaminidase and alpha-mannosidase (p less than 0.01) and a significantly lower plasma activity of alpha-fucosidase and alpha-galactosidase (p less than 0.01). Of the 5 enzymes studied, only plasma beta-hexosaminidase correlated with fasting and postprandial blood sugar (p less than 0.01), cholesterol and triglycerides (p less than 0.05). Additionally, poor control of diabetes was also associated with a significantly higher plasma beta-hexosaminidase activity (p less than 0.01). Proteinuria or an abnormal Addis count suggestive of renal involvement was associated with various changes in plasma acidic hydrolases. These changes may be related to insulin deficiency rather than hyperglycemia and may be genetically determined.

Fabry's disease is a rare hereditary disease transmitted as an X-linked recessive trait with the primary metabolic defect of an enzyme alpha-galactosidase A, resulting in deposition of glycolipids (ceramide trihexoside) in various tissues, including the kidneys. Two sibling cases of Chinese adult male patients in a family with Fabry's disease were completely evaluated including the clinical, pathologic and biochemical studies. Both of the patients had the similar clinical manifestations such as telangiectases, proteinuria, acral pains, corneal opacities, tortuous renal vessels and recurrent fever. Chronic renal insufficiency was noted in Case 1, whereas Case 2 had normal renal function. Microscopic hematuria was noted in Case 1. In renal biopsy, LM showed foamy vacuolation of the glomerular visceral epithelial cells and EM showed widespread myelin bodies (Zebra bodies) in kidney tissues, most numerous in visceral epithelia in both cases. Those findings are diagnostic for Fabry's disease. The plasma activity of alpha-galactosidase of Case 1 was 0.8 and that of Case 2 was 1.0 (normal reference range: 8.5-18.5 nmol/hr/min). The plasma activity of alpha-galactosidase A of Case 1 was 0.4 and that of Case 2 was 0.8 (normal reference range: 7.9-16.9 nmol/hr/min). All the enzyme activities in both cases were much lower than those of normal subjects. In addition to clinical presentations, pathologic study and biochemical study with assays of plasma or serum activities of alpha-galactosidase and alpha-galactosidase A are important steps in the diagnosis of Fabry's disease.(ABSTRACT TRUNCATED AT 250 WORDS)

We present the first female patient to exhibit Fabry-like myelin bodies in the glomerular epithelial cell in association with IgA nephropathy. This previously healthy 36-year-old woman presented with proteinuria and hematuria without skin lesions. Renal biopsy showed typical IgA nephropathy, with paramesangial deposits, mesangial proliferation and scattered myelin bodies. The leukocytic alpha-galactosidase A activity was abnormally low. She had no family history of Fabry's disease nor the characteristic features, such as skin lesion, neuralgia, or hypohidrosis. Fabry's disease is diagnosed from the renal biopsy findings and the activity of alpha-galactosidase A in leukocytes and/or fibroblasts. We diagnosed the present case with Fabry' disease and IgA nephropathy from these results.

Fabry's disease is a rare, inherited, X-linked metabolic storage disease with ceramide hexoside due to alpha-galactosidase A deficiency. Patients with typical Fabry's disease usually present with several clinical manifestations of corneal dystrophy, neurologic abnormalities, cardiovascular disease, heavy proteinuria, and characteristic cutaneous angiokeratoma. However, atypical Fabry's disease with oligosymptomatic phenotype presents with symptoms restricted solely to cardiocytes or kidney and might be diagnosed by chance during a routine endomyocardial or renal biopsy examination. In this article, we report a case of Fabry's disease incidentally diagnosed in a 34-year-old man who presented with intermittent trace or 1(+) proteinuria only. This patient had no history of renal disease in any other family member. A renal biopsy to evaluate trace proteinuria revealed histologic and ultrastructural findings compatible with Fabry's disease. Subsequent to the renal biopsy, a skin biopsy on a few initially unrecognized, scattered, dark-pinkish scrotal papules showed typical angiokeratoma. A biochemical enzymatic assay of alpha-galactosidase in urine and plasma revealed a markedly decreased enzyme level in the hemizygous range.
