Dasatinib-induced pleural effusions, pericardial effusion and pulmonary arterial hypertension: a case report.

BACKGROUND: Pleural effusion, pericardial effusion, and pulmonary arterial hypertension have been shown to have potential associations with the use of dasatinib in adults. However, due to the limited data regarding the efficacy and safety of tyrosine kinase inhibitors (TKIs) in pediatric patients necessities reliance on clinical experience gained from treating adults.

CASE DESCRIPTION: We present a case of a 12-year-old female patient with chronic myelogenous leukemia (CML) who developed significant right-sided pleural effusion, moderate pericardial effusion, and pulmonary arterial hypertension during dasatinib therapy. Dasatinib was promptly discontinued upon identification of these adverse events. This was followed by the use of bosentan for pulmonary hypertension, furosemide and spironolactone diuretics, prednisone anti-inflammatory, and especially a bold attempt to improve pulmonary endothelial permeability with acetyl cysteine aerosolization. At the same time, according to the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) data reported by the patient and combined with the actual situation, the appropriate TKI was selected for the patient to continue the CML treatment.

CONCLUSIONS: FAERS data gathered on OpenVigil indicates that the signal associated with pericardial effusion is stronger among individuals under the age of 18 when imatinib is used instead of dasatinib (exactly the reverse of the results in the adult group). However, this does not imply that dasatinib is safer for the smaller group. In our situation, dasatinib-induced adverse effects include pericardial effusion. As a result, while administering TKIs to pediatric patients, we still need to increase monitoring-particularly for pulmonary and cardiovascular toxicity-and take swift action in the event that a major adverse reaction occurs. In addition, it is important to report these adverse effects as much as possible in order to give pediatric patients utilizing TKIs more helpful information.
