Excretion of total and muscular N tau-methylhistidine and creatinine in muscle diseases. 1984

H J Röthig, and W Bernhardt, and E G Afting

The daily urinary excretions of N tau-methylhistidine and creatinine from 52 adult patients were measured under standardized conditions. The ratio of N tau-methylhistidine to creatinine excretion was calculated on the basis of the total and muscle-specific excretion rates and correlated to the clinical status of the patients. In patients with muscular diseases and in those with diseases of the central nervous system, the total daily excretion of both metabolites was about 30% lower than in controls. The muscle-specific ratio in patients with diseases of the central nervous system and patients with muscular diseases was not different from that observed in controls. Only in patients with neurogenic atrophies was the ratio elevated, so that it was more than twice the control value. The ratio of excreted N tau-methylhistidine/creatinine is only valid as an indicator of myofibrillar protein breakdown after correction for the contribution of nonskeletal muscle tissues to the urinary excretion.
