Clinical characteristics and risk factors of patients with eosinophilic fasciitis associated with pleural effusion

Abstract

To investigate the risk factors of eosinophilic fasciitis (EF) associated with pleural effusion (PE). A retrospective analysis was performed on 22 patients with EF diagnosed by skin biopsy in our hospital, and they were divided into EF-PE and EF according to chest computed tomography examination. The clinical characteristics, clinical manifestations, comorbidities and laboratory test indicators of the two groups were collected and compared, and the risk factors for occurring PE in patients with EF were determined by multivariate logistic regression analysis. Among 22 patients with EF, 8 had PE. The age, course of disease, incidence of fever, weight loss, cough and shortness of breath, pulmonary infection, hypothyroidism, hydronephrosis and kidney stone, swelling rate of small vascular endothelial cells, consolidation shadows, C-reactive protein and thyroid stimulating hormone in EF-PE group were higher than those in EF group, while free triiodothyronine and thyroxine were lower than those in EF group. Age, fever, shortness of breath, C-reactive protein, ESR, thyroid stimulating hormone, pulmonary infection, hypothyroidism, hydronephrosis, kidney stones, swollen small vascular endothelial cells and chest CT consolidation shadows were identified as risk factors for happening PE in patients with EF, while free triiodothyronine and free thyroxine were identified as protective factors against PE in patients with EF. The incidence of EF-PE was 36.36% in this study. Advanced age, high C-reactive protein, ESR, thyroid stimulating hormone, incidence of fever, shortness of breath, pulmonary infection, hydronephrosis, kidney stones, swollen small vascular endothelial cells, chest CT consolidation shadows, and low free triiodothyronine and thyroxine suggest that patients with EF are significantly at increased risk of PE.
