The Protective Effect of The Interleukin 1 Receptor Antagonist on Chronic Thromboembolic Pulmonary Hypertension Model
Özet
Aim: Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the main reasons of severe pulmonary hypertension and has significantly higher morbidity and mortality rates. The pathogenesis of the disease is characterized by the incomplete resolution of acute embolisms. The elevated inflammatory conditions after the acute embolism are one of the critical factors. Therefore, we aimed to investigate whether or not anakinra is an option for treating CTEPH in an animal model. Material/Methods: We studied twenty-one rats in this study They were randomly divided into three groups containing seven animals: the control group: saline-treated control; the embolism group: CTEPH + normal saline; the anakinra group: CTEPH + anakinra. Results: We have observed that the layers of the segmental arteries and the alveolar were normal in the control group. In the cardiac tissue it was observed that muscular tissues and connective tissue were normal in the right ventricle. In embolism group, we detected a widening of the alveolar septum, a surrounding the alveolar infiltrates and a thickening of the segmental arteries in the muscular layer and a hypertrophy in the right ventricle tissues. We have determined that the lung and cardiac tissue specimens in the anakinra group are similar to control group. Conclusions: We have showed that anakinra was useful option for the CTEPH model in rats. Anakinra may be considered as protective effect and the regression of the increased inflammation in CTEPH. The effectiveness of anakinra will continue to be subject to the further experimental and clinical studies.
