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

The management of chronic rhinosinusitis with nasal polyps (CRSwNP) is challenging due to disease recurrence and adverse effects. Both surgical and medical treatment modalities impact the quality of patients' lives. Monoclonal antibody treatment has recently been used successfully in CRS with limited reported adverse events. We aimed to review the literature to shed more light on the safety and adverse events associated with the biological therapy of CRSwNP. A comprehensive systematic review was conducted on the safety of different biological treatments when used for managing CRSwNP. We have included 13 studies in the present systematic review, including 12 randomized controlled trials (RCTs) and one cross-sectional study. The total sample size for the included studies was 2282 patients. Six studies investigated the safety and adverse events of dupilumab; three investigated omalizumab, three investigated mepolizumab, and only one investigated reslizumab. Some studies have reported that adverse events were common with these types of drugs. However they were not specific and self-limited. Headaches, injection site reactions, and pharyngitis were the most common adverse events found among the reported adverse events. The Dupilumab trial reported pharyngitis in 225 patients (22.4 %) followed by erythema in 9.4 %, headache in 8.1 %, epistaxis in 5.1 %, and asthma in 1.7 % of patients. Trials which used omalizumab reported headaches, nasal pharyngitis, injection-site reactions to be the most common adverse events with estimated prevalence rates of 8.1 %, 5.9 %, and 5.2 %, respectively. Mepolizumab and reslizumab studies reported that 40 % of patients were complicated by nasal polyps/congestion/pharyngitis/infections, 14 had a headache (15.5 %), two developed asthma (2.2 %), and only one patient (1.1 %) had epistaxis as an adverse event. Although the literature's current investigations indicate the safety of the biologic treatment modalities, further studies are needed as some uncertainty among the trials have been reported.

Superior oblique myositis mimics a subperiosteal abscess in a patient with sinusitis / Miosite oblíqua superior mimetiza abscesso subperiosteal em paciente com sinusite

ABSTRACT Isolated superior oblique myositis is a rare variant of idiopathic orbital myositis. We are reporting for the first time the case of a 19-year-old woman who had isolated superior oblique myositis with sinusitis that mimics a subperiosteal abscess. Despite the typical history of upper respiratory tract infection and laboratory test results and initial radiological findings suggestive of orbital cellulitis secondary to sinusitis, the initial response to systemic steroid with subsequent imaging changes and the relapse after cessation of steroid therapy helped us reach the diagnosis.

RESUMO A miosite oblíqua superior isolada é uma variante muito rara da miosite orbital idiopática. Trata-se do primeiro relato de uma mulher de 19 anos como um caso de miosite oblíqua superior isolada com sinusite que mimetiza abscesso subperiosteal. Apesar da história típica de infecção do trato respiratório superior, exames laboratoriais e achados radiológicos iniciais sugestivos de celulite orbital secundária à sinusite, a resposta inicial ao esteróide sistêmico com subsequentes alterações de imagem e recaída, após a cessação do esteróide, nos ajudou a alcançar o diagnóstico.
