    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.

    Description / Table of Contents: Zusammenfassung Es werden Methoden dargestellt, mit denen eine quantitativ geringe Cystathioninausscheidung im Urin festgestellt und bewiesen werden kann. Es wurden 5 Kinder gefunden, die eine mäßige Cystathioninausscheidung aufwiesen (14,5–99,0 μMol/Tag). Die klinischen Befunde dieser Patienten werden dargestellt. Drei von ihnen hatten Leberaffektionen, eines eine nichtketotische Hyperglycinämie, und bei einem Kind handelte es sich um ein Neugeborenes mit multiplen Fehlbildungen. Bei allen Fällen lag eine sekundäre Cystathioninurie vor. Die Ursachen, die zu einer sekundären Cystathioninurie führen, werden besprochen.
    Notes: Abstract A secondary cystathionuria was found in two children with liver disease (cirrhosis of unknown etiology, congenital biliary atresia), in one infant with hypercalcemia due to high doses of vitamin D, in one case of non-ketotic hyperglycinemia, and in one infant with multiple malformations. Methods for the determination of cystathionine, when excreted in only small amounts, are outlined.
