Lipid profile was evaluated prospectively in 23 consecutive children,
aged 3.2-14.9 years, admitted to the hospital with a febrile illness (
pneumonia, upper respiratory tract infection, diarrhea, pyelonephritis
, mononucleosis, appendicitis). The degree of dyslipidemia associated
with fever was assessed using each child as his/her own control and by
comparison with 93 non-febrile children who had no evidence of fever
during the past six months. Total cholesterol decreased during the sym
ptomatic phase of the discase. The magnitude and duration of its decre
ase appeared to be related to the degree and duration of fever. Low HD
L-cholesterol and hypertriglyceridemia were observed during the late s
tage of the febrile disease and were still detected in the convalescen
t phase. This study suggests that in children, transient and sometimes
prolonged lipid changes may occur in association with an infectious f
ebrile disease. This effect is important for defining the appropriate
timing for screening for dyslipidemias.
