Bile acid profiles in bile, urine, and feces of a patient with cerebrotendinous xanthomatosis.

Bile acid profiles of bile, urine, and feces obtained from a patient with cerebrotendinous xanthomatosis on the same day have been analyzed by gas-liquid chromatography-mass spectrometry after fractionation into groups by mode of conjugation by an ion-exchange chromatography. The predominant biliary bile acid was cholic acid conjugated with glycine and taurine. Lesser amounts of the amino acid conjugates of chenodeoxycholic acid, ursodeoxycholic acid, 7-ketodeoxycholic acid, allocholic acid, and deoxycholic acid, and of unconjugated norcholic acid and allonorcholic acid were also present in the bile. The major fecal bile acid was 7-epicholic acid. Relatively large amounts of bile acids were excreted in the urine. Unconjugated 7-epicholic acid, norcholic acid, allonorcholic acid, and cholic acid predominated. The bile acid profiles of the patient were different from those of normal subjects and should be useful for the diagnosis.

Simultaneous occurrence of minimal change glomerular disease, sarcoidosis and Hashimoto's thyroiditis.

We herein report a very rare case of a patient suffering from simultaneous occurrence of three immune disorders, i.e. Hashimoto's thyroiditis, sarcoidosis and minimal change glomerular disease. A 66-year-old man was admitted to our hospital for evaluation of nephrotic syndrome. Six months before admission, he was pointed out as having positive proteinuria, hypoalbuminemia and associated pretibial pitting edema. Initial laboratory data showed high gammaglobulinemia, high titers of both antimicrosomal and antithyroglobulin antibodies with normal thyroid function. Chest X-ray and CT scan revealed bilateral hilar lymphadenopathy with interstitial shadow. Ga-citrate scan disclosed positive accumulation in the thyroid glands, the mediastinum, the lungs and the kidneys. The diagnosis of minimal change nephritic syndrome and pulmonary sarcoidosis was made, based on the findings of transbronchial lung biopsy and kidney biopsy. After one and a half months of admission, thyroid function had gradually deteriorated. The histological findings of the thyroid were consistent with the features of Hashimoto's thyroiditis. Treatment with prednisolone and cyclophosphamide resulted in a decrease in urinary protein excretion, reduction in the size of mediastinal lymphadenopathy and disappearance of positive findings of Ga-citrate scan in the thyroid glands and the kidneys. Simultaneous occurrence of minimal change-glomerular disease, sarcoidosis and Hashimoto's thyroiditis in our case suggests that similar immunological abnormalities may be involved in the pathogenesis of the diseases.
