[Pregnancy and delivery in women with thrombocytopenia].

Maternal immune thrombocytopenia is a frequent finding in pregnancy and is most commonly asymptomatic and clinically benign. 8 pregnant women with thrombocytopenia between January 1995 and December 2000, in Clinic of Obstetrics and Gynecology in Katowice-Ligota, were evaluated. 7 patients had idiopathic thrombocytopenia purpura and one (31 years old) had cirrhosis, splenomegaly, thrombocytopenia and elevated liver enzymes. 6 cases was steroid-treated with initial platelet count 4,000 per cubic millimeter to 115,000 per cubic millimeter after treatment. Alloimmune thrombocytopenia is a serious fetal disorder, resulting from platelet-antigen incompatibility between the mother and fetus. Among all newborns only one had thrombocytopenia, platelet count 45,000 per cubic millimeter, without neonatal intracranial hemorrhage. 6 women had cesarean section and 2 patients delivered naturally.

Lipid mobilizing activity in the blood of obese patients during prolonged fasting.

Lipid mobilizing activity is lowered in the serum of obese patients. During short-term fasting, this activity increases in non-obese subjects. The present study was concerned with the changes in lipid mobilizing activity in the blood of obese patients during prolonged fasting, and with the behavior of esterified and free fatty acids. Serum levels of free fatty acids in the control subjects were significantly lower than in the obese women. During a 14-day period of complete fasting, levels of free fatty acids increased in all cases. In non-obese subjects this was accompanied by a significant rise in lipid mobilizing acitivity, but in obese subjects no significant change took place in this activity. The findings indicate that high levels of free fatty acids in obese persons during fasting are caused by inhibition of their esterification.
