Pericarditis and perimyocarditis associated with active Mycoplasma pneumoniae infection.

In 13 patients an association existed from 1970-73 between Mycoplasma pneumoniae infection and acute pericarditis (in eight) or perimyocarditis (in five). In 12 patients the association was moderately probable, with a fourfold rise in complement-fixing antibody titers between acute and convalescent phase sera being noted. In the last patient, a lesser-order association was found using only convalsecent phase serum. The presence of influenza, herpes simplex, Coxsackie B, or adenovirus was excluded by serologic testing. Acute illness was variable, with four patients developing heart failure. Long-term evaluation (mean, 47 months) found eight patients asymptomatic and three symptomatic. Two patients died. Residual effects of the Mycoplasma infection seemed at least partially responsible in one compromised patient and in one who died. Mycoplasma infection should be considered in the presence of acute cardiovascular decompensation, especially when preceded by upper respiratory infection, and added to the possible causes of idiopathic cardiomyopathy.

A method for the purification of milligram quantities of stable human phosphatidylcholine-cholesterol acyltransferase.

A method for processing 3 litres of human plasma for the purification of phosphatidylcholine-cholesterol acyltransferase is described. The method involves (NH4)2SO4 fractionation, citric acid treatment, and DEAE-cellulose and hydroxyapatite chromatography. At this stage the enzyme preparation is purified approx. 8000-fold. This preparation appears to be free of lipoproteins as determined by immunoelectrophoresis against anti-human serum and is minimally contaminated with albumin (less than 30 mug/mg of enzyme protein) as determined by immunodiffusion. The activity of the enzyme was stable for 4 days, but most of its activity was lost after 20 days On electrophoresis on 5% polyacrylamide gel, a fast-moving band with enzyme activity and a slow-moving band with no enzyme activity was observed. A faint band of albumin was also present. Extracts of enzymically active bands cut from ten gels and then pooled and extracted with 0.15 M-NaC1/4mM-sodium phosphate, pH 7.0, showed a single band on re-electrophoresis on 5% polyacrylamide gel.
