| Popis: | Aim. To ascertain the role of platelets in pathogenesis of clinical symptoms in patients with Q-fever. Material and methods. We studied hemostasis with estimation of functional platelet activity in 49 patients with Q-fever. Results. Hemorrhagic syndrome (HS) occurred in 34,4 % patients with Q-fever (QF) during seasonal rise of morbidity. HS manifested with petechiae (12%), hematomas (32 %), nasal bleeding (17 %), stomatorrhagia (9 %), melena (12 %). Characteristics and duration of such symptoms as weakness (100%), myalgia (72%), arthralgia (52.9%) suggested hemocoagulatory disorders as a cause of the symptoms appearance. At the height of the disease thrombocytopenia was accompanied with inhibition of platelet aggregation activity, but regression of the clinical symptoms was associated with an increase in platelet count and platelet hyperaggregation. Fibrinogen content was elevated during hospitalization in 50% patients. Conclusion. Clinical manifestations of HS are typical for Q-fever prevalent in the Astrakhan Region. Hemostatic disorders because of altered functional activity of platelets were registered in all the cases and evidence for pathogenetic unbalance of homeostasis in Q-fever patients. |
