These patients had a higher prevalence of concomitant anti-asthmatic medication. chart review, mean follow-up was 20.4??15.7?months. All patients underwent ASA desensitization. Twenty-one patients experienced eventually discontinued therapy after 5.8??4.5?months; 11 for its side effects, 12 for its inefficacy. Twenty patients developed sinunasal complaints soon thereafter. Ten patients were still undergoing Rifapentine (Priftin) desensitization (mean duration 15.3??15.7?months). These patients had a higher prevalence of concomitant anti-asthmatic medication. Seventeen refractory patients underwent systemic dupilumab therapy. Rifapentine (Priftin) After 6.4??2.7?months of treatment, sinunasal end result test (68.1??13.9 vs 20.1??13.9) and visual analogue scales of overall complaints (8.7??0.9 vs 2.2??1.5) as well as endoscopic findings and olfactory function (brief smell identification test; 3.5??2.6 vs 8.6??2.4) all improved significantly. A considerable number of patients with Samter triad discontinued ASA desensitization, equally for ineffectiveness or side effects. If desensitization is to be effective, special care needs to be taken in respect to concomitant anti-asthmatic medication. Dupilumab is usually highly effective and safe in treating refractory patients. test, as appropriate, was used. Statistical differences of 0.05 were considered to be significant. 3.?Results Overall, 31 patients were included in the study at hand. Average age was 45.9??15.4?years; out of the patients included, 14 were male and 17 female. On average, each patient experienced undergone 3.1??1.3 previous FESSs. Mean follow up of all patients was 20.4??15.7?months. Out of the 31 patients, 21 experienced discontinued oral desensitization. Average age of these patients was 47.0??13.7?years, with a male to female ratio of 11 to 10. On average, oral desensitization was tolerated for 5.8??4.5?months, ranging from 0.5 to 15?months (Fig. ?(Fig.1).1). The main reasons to discontinue oral desensitization were Rabbit Polyclonal to OR10A5 recurrence of nasal polyps (12 patients), and side effects (11 patients), where 5 patients suffered from increased asthma, 2 patients suffered from urticarious skin reactions and gastrointestinal pain, respectively, and 1 patient suffered from renal side effects and bleeding, respectively. Out of the patients where ASA desensitization was unsuccessful, 20 eventually developed nasal symptoms again that caused them to seek medical attention. Average time from beginning of desensitization until the recurrence of symptoms was 7.6??4.6?months, ranging from 1 to 17?months (Fig. ?(Fig.2).2). The 10 patients that still underwent oral desensitization were on average 43.5??18.1?years, with a male to female ratio of 5:5. Average duration of oral desensitization was 15.3??15.7?months, ranging from 2 to 60?months (Table ?(Table11).

This was in the majority of cases due to side effects or due to ineffectiveness. Generally speaking, side effects that limit ASA desensitization have been reported in almost every study that resolved this topic (Table ?(Table4).4). Interestingly, even low doses such as 350 or even 100?mg per day seem to yield relevant side effects as has been reported in other studies.[9] In that respect, our findings are in line with the relevant literature. However, the fact that almost one third of patients developed recurrence of nasal polyps while undergoing desensitization is considerable.
