Platelet counts and their morphologic parameters in patients with
Lyme borreliosis before and after antibiotic therapy (4 weeks of treatment) were estimated. 30 patients aged 17-60, x = 41 were evaluated: 7 with Erythema migrans, 3 patients with neuroborreliosis in the from Lymphocytic meningitis and 20 ones with
Lyme arthritis. Control group consisted of 19 healthy persons aged 34-52, x = 43. Hematologic analyser Coulter MAXM was used for testing PLT, MPV, PCT and PDW. The results indicated that patients with
Lyme boreliosis have decreasing platelet count with simultaneously increasing their volume in comparison with healthy control. It may result from the involement of platelets in defense mechanisms of infected host. The decrease of platelet count after the antibiotic treatment in comparison with the control group may be the reflection of influence of antibiotic treatment on thrombopoesis.
