Adverse events of biological therapy in chronic rhinosinusitis with nasal polyps: A systematic review.

Chronic Rhinosinusitis with Nasal Polyps: A Look at Biological Therapy

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a condition that affects the sinuses and nasal passages, causing inflammation and the growth of polyps. This research delves into the world of biological therapy for CRSwNP, specifically focusing on the safety and adverse events associated with these treatments. It involves a comprehensive systematic review of 13 studies, including 12 randomized controlled trials and one cross-sectional study, involving a total of 2282 patients. The researchers examined the safety of various biological therapies, such as dupilumab, omalizumab, mepolizumab, and reslizumab, while scrutinizing the reported adverse events associated with each.

Unveiling the Safety Profile of Biological Therapy

The study's findings indicate that biological therapy for CRSwNP appears generally safe, with adverse events often being common but not severe. The most frequently reported adverse events include headaches, injection site reactions, and pharyngitis, which were typically self-limited, meaning they resolved on their own without requiring specific treatment. For instance, the Dupilumab trial reported pharyngitis in 22.4% of patients, followed by erythema (9.4%), headache (8.1%), epistaxis (5.1%), and asthma (1.7%). Trials using omalizumab reported headaches, nasal pharyngitis, and injection-site reactions as the most common adverse events, with estimated prevalence rates of 8.1%, 5.9%, and 5.2%, respectively. Mepolizumab and reslizumab studies revealed that 40% of patients experienced complications such as nasal polyps, congestion, pharyngitis, or infections, while 15.5% had headaches, 2.2% developed asthma, and only 1.1% had epistaxis as an adverse event.

Navigating the Uncertainties of Biological Therapy

While the current evidence suggests biological therapy for CRSwNP is generally well-tolerated, the researchers acknowledge some uncertainties within the available research. They emphasize the need for additional studies to address these uncertainties and further refine our understanding of the safety profile of these therapies.

Dr. Camel's Conclusion

It's fascinating how biological therapy is changing the landscape of chronic rhinosinusitis treatment. Think of it as a way of re-training the immune system to better tolerate the nose and sinus passages. But just like a camel navigating a desert, we must always be aware of potential hazards and uncertainties. Further research will help us confidently navigate the vast and complex world of biological therapy for CRSwNP, ensuring the safety and well-being of our patients.
