    Notes: Abstract To evaluate effective renal plasma flow (ERPF) we performed renal scintigraphies with99mTc-Mercaptoacetyl-triglycine (MAG3) in ninepatients with glycogen storage disease I (GSD I) (age: 16±7 years). Two patients presented with proteinuria, none showed hyperaminoaciduria, disturbed tubular reabsorption of phosphate or hypertension.99mTc-MAG3 clearance values were elevated in eight out of nine patients (865±233 ml/min/1.73 m2 body surface area) and exceeded the agedependent mean values by 21%–145%. ERPF values in patients with poor metabolic control were higher than in patients with long-term good metabolic control (988±186 vs. 619±55 ml/min/1.73 m2;P〈0.05). We conclude that enhanced ERPF is a common finding in GSD I patients, which preceeds clinically overt nephropathy. Renal scientigraphy with99mTc MAG3 is a suitable method for the early detection and monitoring of kidney dysfunction in GSD I.

    Description / Table of Contents: Summary In 40 patients with Alzheimer’s disease (AD), in 5 patients with non-AD dementia and in 36 cognitively normal controls the concentration of protein tau was determined in the cerebrospinal fluid (CSF). Of the AD patients, 19 were very mildly demented (MMSE score from 25 to 28). Even in these patients, CSF tau was significantly more elevated than in controls. In the non-AD patients protein tau was less increased. Among the AD patients there was no association between CSF tau and severity of cognitive impairment or deficit in cerebral blood flow, determined by SPECT. Our findings suggest that CSF tau may be elevated even at the predementia stage of AD and be useful as a biological marker for the early recognition of the disease.
    Notes: Zusammenfassung Bei 40 Alzheimer-Patienten, 5 Patienten mit Demenzen anderer Ursache und 36 kognitiv unauffälligen Kontrollpersonen wurde das Tau-Protein im Liquor cerebrospinalis bestimmt. Von den Alzheimer-Patienten befanden sich 19 in einem sehr leichtgradigen Stadium der Krankheit (Summenwert im Mini-Mental-State-Test 25 bis 28 Punkte). Auch bei diesen wurde gegenüber den Kontrollpersonen eine signifikante Erhöhung von Tau gemessen. Eine weniger ausgeprägte Erhöhung von Tau zeigte sich bei den Patienten mit anderen Demenzen. Bei den Alzheimer-Patienten fand sich kein quantitativer Zusammenhang zwischen der Erhöhung von Tau und dem Schweregrad der Demenz oder dem zerebralen Perfusionsdefizit, bestimmt mit SPECT. Die Ergebnisse sind ein Hinweis, daß Tau auch im prädementiellen Stadium der Alzheimer-Krankheit erhöht sein könnte und sich als biologischer Indikator für die Früherkennung eignet.
