[Blood levels of 6-keto-prostaglandin F1alpha, thromboxane and prostaglandin F2alpha in patients with bronchial asthma].

The study revealed the relation of bronchial asthma (bacterial variant) clinical pattern to plasma levels of PGF2 alpha, 6-keto-PGF1 alpha and TxB2. In remission of the disease the above indices are lower. Severe asthma remission is characterized by higher levels of 6-keto-PGF1 alpha and TxB2 than moderate asthma one, demonstrates a tendency to growing PGF2 alpha levels. A rise in PGF2 alpha and TxB2 in manifest asthma points to their participation in bronchospasm formation suggesting an active role of these bronchoconstrictors in asthma pathogenesis. Higher levels of 6-keto-PGF1 alpha are of a compensary nature in the pathogenesis of PGF2 alpha and TxB2 bronchoconstrictory action, and of damaging nature contributing to the formation of bronchial mucosa edema and bronchial gland hypersecretion.
