Abstract
Serum lipoprotein, apoprotein and lipid levels were studied in 110 healthy children and 30 children with mycoplasma pneumoniae infection.
Results are as follows:
1) No dietary influence was observed on the concentrations of apoproteins (A-I, A-II, B, C-II and E) in healthy children, when the blood samples were taken, preprandial and 2 to 3 hours postprandial.
2) HDL-C levels were reduced in almost all patients with mycoplasma infection at the acute stage, but were returned to almost normal during recovery.
3) HDL2-C level was markedly lowered, compared with that of HDL3-C, in the patients at the acute stage, which may account for the decrease of HDL-C concentration.
4) A significant decrease of apoprotein A-I and A-II levels, and a significant increase of apoprotein B level at the acute stage returned to almost normal during the recovery.
5) The above data being compatible with the variations of lipoprotein and apoprotein observed in atherosclerotic state, mycoplasma infection might be a possible risk factor in the development of atherosclerosis.
