The role of corticosteroids in preventing invasive procedures in patients with parapneumonic effusion in the exudative phase: An observational study.

The aim of the study was investigate the effect of corticosteroid use on the need for invasive procedure like tube thoracostomy with underwater seal drainage (TT-UWSD) and Video Assisted Thoracoscopic Surgery (VATS) in adult patients diagnosed with parapneumonic effussion in the exudative phase. A retrospective cohort study was performed in a chest diseases hospital. A total of 65 patients were included in the study. While 30 patients received only medical treatment, 35 patients underwent invasive procedures. Data on characteristics, vital signs, and laboratory parameters were recorded from electronic medical records. Univariate and multivariate logistic regression analyses were performed to identify corticosteroid and other predictors of the need for invasive procedures. The outcomes of the multivariate regression analysis revealed that an longer duration of symptoms (OR = 1.10, 95% CI: 1.01-1.21, P < .033) and the presence of dyspnea (OR = 5.44, 95% CI: 1.26-23.50, P < .023) independently associated with an increased need for invasive procedures, while corticosteroid treatment (OR = 0.15, 95% CI: 0.02-0.81, P < .028) was observed to be associated with a reduced necessity for invasive procedures. Treatment with metilprednisolone, together with the absence of dyspnea and shorter symptom duration may independently decrease the need for invasive procedure in patients with parapneumonic pleural effusion in the exudative phase.
