    Notes: Abstract We report on two siblings suffering from a new congenital tubulopathy. Following normal pregnancies not complicated by polyhydramnios, severe renal losses of potassium, chloride, sodium and magnesium occurred in the first weeks after birth. Calcium metabolism was not affected. The distal tubular chloride reabsorption was considerably decreased in the two siblings (0.25 and 0.28, respectively). Secondary hyperaldosteronism, activation of the kallikrein-kinin system and elevated urinary prostaglandin excretion were observed. The effects of indomethacin, spironolactone and captopril on symptoms, electrolyte wasting, activation of renin-angiotensin-aldosterone and kallikrein-kinin system and prostaglandin synthesis were studied. In spite of persisting elevation of prostaglandin synthesis, captopril decreased electrolyte wasting, polyuria and hyperaldosteronism most effectively. Conclusion We delineate an apparently new disorder characterized by a postnatal onset, an extremely decreased chloride reabsorption with extensive hyperchloriduria and hypermagnesiuria in the presence of normal calcium metabolism. The disorder can be distinguished from other tubulopathies with hypokalaemic alkalosis.

    Atypical vitamin B12-unresponsive methylmalonic aciduria in a sibship with severe progressive encephalomyelopathy: A new genetic disease? (1996)

    Notes: Abstract We report on two siblings, a girl of 7 years and a boy of 2 years, who presented in infancy with hypotonia, athetoid movements, myopathy and severe developmental delay. The progressive clinical course was characterized by ophthalmoplegia, pyramidal tract signs, loss of visual contanct and failure to thrive. The older sister died at the age of 7 years. The younger brother followed an almost identical clinical course. MRI of the brain revealed bilateral hypodensities and atrophy of the putamen. Neurophysiological investigations were consistent with peripheral neuropathy. Investigations for neurometabolic disorders in urine, plasma and CSF of both patients revealed a consistent increase of methylmalonic acid in urine, plasma and CSF as well as borderline low free GABA in CSF. Except for an inconstant elevation of lactate in the boy, metabolic acidosis, hypoglycaemia, episodic ketoacidosis, or hyperammonaemia, the usual concomitants of organoacidopathies, were absent in both children. Homocystinuria was excluded. Methylmalonic aciduria did not respond to antibiotic treatment, vitamin B12 therapy nor dietary protein restriction. Incorporation of [14C]propionate into protein in cultured fibroblasts was pathologically but inconsistently decreased. Both patients' cell lines showed only minimal response to hydroxocobalamin and normal methylmalonyl-CoA mutase activity. Conclusion Even though the definitive undorlying enzymatic defect in this sibship remains obscure our results suggest a new genetic disorder. This report illustrates that hitherto undescribed metabolic disorders remain to be elucidated even in long investigated areas of intermediary metabolism such as methylmalonic aciduria.

    Notes: Abstract The amino acid composition of food products frequently used in the diets of amino acid and protein disorders – including tryptophan – was estimated using ion-exchange column chromatography and high performance liquid chromatography. It includes fruits (different varieties of apples, pears, ananas, bananas, peach, strawberries, honey melon, water melon, kiwi, plums, grapes), vegetables (different varieties of potatoes, potato products, cauliflower, broccoli, cabbages, spinach, olives, lettuce, cucumber, peas, mushrooms) and commercially available or home-made food products (meat broth, fine gravy paste, ketchup, liquid seasoning, soja sauce, different varieties of Chinese noodles, sausages for phenylketonuria patients), and different new fiber concentrates.
