A SLE course has been analyzed retrospectively in pregnancy and after
delivery for 34 patients (44 pregnancies). Aggravation of the disease
was registered in 6 cases (13.5%). Only two of them received prophylac
tic corticosteroid maintenance. Two SLE patients with unaffected kidne
ys had no pregnancy-related SLE exacerbations though they developed ne
phropathy of the pregnant. After delivery the disease aggravated in 12
patients (27.3%). Five patients had moderate exacerbations within hal
f a year after the delivery, seven patients developed severe exacerbat
ions within 3-11 postnatal months. Five out of seven women presented n
ephrotic syndrome. One of the patients died of rapidly progressive glo
merulonephritis. Three women had renal damage after the delivery as in
itial condition. SLE exacerbations were reported more frequently in yo
ung patients (under 30, in 15 of 31 pregnancies) than in older ones (o
ver 30, in 3 of 13 pregnancies). Postnatal SLE aggravations can be pre
vented by large doses of prednisolone (20-30 mg/day) administered for
2-3 weeks.
