The Efficacy of Budesonide as Intrapolyp Injection Agent in the Management of Type 2 CRSwNP.

Objectives: To assess the efficacy and safety of budesonide as an intrapolyp injection in chronic rhinosinusitis with nasal polyps (CRSwNP) in comparison to control and systemic steroids.

Method: In a prospective double-blinded controlled randomized clinical trial, 150 patients with CRSwNP were divided into 3 groups in a ratio 1:1:1 where group (A) was given oral prednisolone 1 mg/kg tapered daily for 2 weeks, group (B) was given budesonide intrapolyp injection weekly for 5 consecutive weeks, and group (C) was given intrapolyp injection with saline as the control group. Patients were assessed upon Sinonasal Outcome Test (SNOT-22) score, Total Nasal Polyp score (TNPS), Serum IgE, absolute eosinophilic count, and morning cortisol level before treatment, 1 week and 6 months after completing their treatment protocol.

Results: SNOT 22 score improved significantly in all groups compared to those at baseline. Reduction in the oral and injection groups was much greater than the control group (P < 0.001), (P < 0.001), and the same trend concerning TNPS score (P < 0.001), (P < 0.001) but with no significant change in the control group.

Conclusion: Intrapolyp steroid injection is considered a safe and effective method in nasal polyposis with limited side effects in comparison to systemic steroids. Using Budesonide as an agent for intrapolyp injection appears to be promising. It's advisable in patients with multiple relapses or high-risk patients to avoid repeated courses of oral steroids.
