Abstract
Introduction. BCR-ABL tyrosine kinase inhibitors are currently used to successfully treat chronic myeloid leukemia (CML). Drug therapy is carried out in a continuous daily mode throughout the patient’s life. Treatment with this group of drugs is associated with specific dermatological adverse events (dAE), which can lead to a change in the regimen of effective, vital therapy for CML patients.Purpose. To study the characteristics of dermatological adverse events, the severity and influence on the quality of life of BCR-ABL tyrosine kinase inhibitors.Patients and methods. The observational study included 93 patients. The clinical manifestations of dAE, their severity were evaluated, their photographs and pathomorphological studies of skin biopsy samples were performed, cases of dose reduction or drug withdrawal due to dAE were recorded. The quality of life of patients with dAE was determined based on the assessment of the dermatological index of quality of life.Results. Imatinib therapy was accompanied by a maculopapular rash in 43.3 % of patients, nilotinib caused follicular keratosis in 12.9 % of patients. In 3.2 % of patients, dasatinib caused hyperpigmentation, in 2.2 % of patients lichenoid rashes of the II degree occurred during treatment with bosutinib. Ponatinib treatment was followed by dAE in 9.7 % of patients. All dAE have an impact on the quality of life of patients, but the maculopapular rash and dyskeratotic changes are most pronounced. In a pathomorphological study, these dAE have specific features corresponding to immuno-mediated dermatitis.Conclusions. The most frequent and pronounced dAE that significantly affect the quality of life of patients with CML are a maculopapular rash and dyskeratotic skin changes: psoriasiform and lichenoid dermatitis. Clinical and pathomorphological characteristics of skin reactions make it possible in the future to determine effective methods of supportive therapy for dAE.
