Profiles of urinary volatiles from metabolic disorders characterized by unusual odors.

The profiles of urinary volatiles from patients with phenylketonuria, maple syrup urine disease, isovaleric acidemia, or trimethylaminuria (fish-odor syndrome) were in each case vastly different from the normal urinary volatiles profile. In the maple syrup urine disease case, metabolites that occur distal to the block were found and a mechanism for their formation is suggested. A new major metabolite in isovaleric acidemia was also found. As well as providing a reliable diagnostic tool for diseases characterized by odors, the analysis of urinary volatiles may provide information to help our understanding of still unexplained aspects of the diseases.

Gemfibrozil--a new lipid lowering agent.

Thirty patients with type II and IV hyperlidemia were studied by a double blind cross over technic. Gemfibrozil at dosages of 1200 mg and 1600 mg a day was compared to 2000 mg daily of clofibrate. The effect of each drug regimen is described for the entire study population and for those who were found to be responders.

Effect of gemfibrozil on serum lipid levels.

A short term investigation of the effect of Gemfibrozil in 1200 mg daily doses has been carried out in a group of 20 Swedish males, 9 Lp[a+] and 11 Lp[a-]. The effect of 8 weeks of treatment upon serum lipids resembled those found in previous trials, with a significant decrease in serum total cholesterol. In this series, even VLDL cholesterol and apoB levels decreased significantly. With the apparent exception of HDL cholesterol, there was no suggestion that Lp[a+] individuals responded less well to treatment than did Lp[a-] individuals.
