[Level of GM-CSF and IL-4 in serum of children with bronchial asthma]. / Stezenie GM-CSF oraz IL-4 w surowicy dzieci z astma oskrzelowa.

Serum IgE, GM-CSF and IL-4 concentrations were measured in 35 children (3 to 18 years of age) with bronchial asthma in I and II clinical stage. Control group consisted of 10 healthy children (6 to 9 years of age) without any symptoms of inflammatory process. All measurements were performed by ELISA tests. The concentration of serum IL-4 was statistically significantly higher in children with bronchial asthma (0.06 ng/ml) than in the control group (0.01 ng/ml). Serum concentration of GM-CSF was lower in children with bronchial asthma than in control group (4.4 and 8.44 pg/ml respectively).

[Chlamydia-induced pneumonia in children]. / Die durch Chlamydien verursachte Lungenentzündung bei Kindern.

Three cases of pneumonia caused by Chlamydia were observed. The disease ran a protracted course and was refractory to treatment. Erythromycin was given initially intravenously and then orally, with improvement of the general condition of children and regression of inflammatory changes in the lungs. Such cases are worth of reporting in view of only isolated reports on respiratory infections caused by these organisms.
