[Evaluation of the impact of symptomatic gastroesophageal reflux disease on the result of surgical treatment with the use of endoscopic techniques and postoperative pharmacological treatment in patients with chronic sinusitis]. / Ocena wplywu objawowego refluksu zoladkowo-przelykowego na wyniki chirurgii endoskopowej i pooperacyjnej farmakoterapii u chorych z PZZP.

It is estimated that in Europe 10% of adults suffer from chronic sinusitis. Chronic sinusitis can be caused by many different diseases that share chronic inflammation of the sinuses as a common symptom. Rhinitis can be caused by stomach acid coming up from the stomach into the esophagus, which successively can result in chronic sinusitis. The current gold standard for diagnosing GERD is--bothersome for the patient--24 h esophageal pH monitoring. This method can be unpleasant for the patients, which makes it less acceptable. Because of that the criteria for symptomatic GERD were made an alternative diagnostic way. We acknowledge that the presence of heartburn and stomach acid coming up from the stomach into the esophagus at least once a week can be diagnosed as symptomatic GERD. The aim of the study is the assessment of the frequency of symptomatic GERD in patients operated because of chronic sinusitis and impact of symptomatic GERD on the follow-up treatment up to 12 months after endoscopic nasal surgery. The authors analysed 144 patients operated at the JUCM Otolaryngological Clinic in Kraków between 2011 and 2013 because of sinusitis. The inclusion criteria were: diagnosed chronic sinusitis, indications for endoscopic sinus surgery, and a written consent for the research. Each patient was examined laryngologically and surveyed. Patients were divided into two groups: with and without symptomatic GERD. We analysed the symptoms in patients treated for sinusitis with or without GERD before, between 3 and 6 as well as in the 12th month after endonasal surgery. Moreover, we analysed the intensity of the global symptoms (expressed in the VAS scale) and separately for each of the 13 symptoms of chronic sinusitis (expressed on a scale 0 - 3). We established that 33 out of the 144 patients (22.9%) qualified for the first survey reported the symptoms of GERD. In the second survey, which was conducted between 3 and 6 month after ESS, 24 out of 119 (20%) people reported the symptoms and in the third survey, which took place in the 12th month after ESS, 14 out of 52 patients reported symptomatic GERD. The intensity of global symptoms rated in the VAS scale in patients with chronic sinusitis during the first survey was 7.8 and in the second and third survey the intensity was 4.2 and 4.3 respectively. But in patients without any symptoms they were 7.4, 2.8, 3.2. We also analysed 13 symptoms of chronic sinusitis rated on a scale 0 - 3. The result of the research was that in patients with symptomatic GERD, even after FESS and the appropriate follow-up, we can still suspect such symptoms as streaming the fluid over the back side of the throat, cough, pain or the feeling of fullness in the ear, headache or halitosis. We should take it under consideration during qualification for the surgery as well as predicting the results of the treatment. Further research is required to state if and how different methods and procedures used in case of patients with symptomatic GERD can reduce the uncomfortable influence of this disease on the effects of chronic sinusitis treatment.

Incidence of aspirin hypersensitivity in patients with chronic rhinosinusitis and diagnostic value of urinary leukotriene E4.

INTRODUCTION: Chronic rhinosinusitis (CRS) with nasal polyposis (NP) may be associated with hypersensitivity to nonsteroidal anti-inflammatory drugs, representing a syndrome of aspirin-exacerbated respiratory disease (AERD). OBJECTIVES: The aim of the study was to validate a simple measurement of urinary leukotriene E4 (uLTE4) excretion for the diagnosis of AERD in patients with CRS and indication for surgery. PATIENTS AND METHODS: Subjects requiring functional endoscopic sinus surgery (FESS) were recruited from the Department of Otolaryngology (n = 24). Before surgery, a standard oral placebo-controlled aspirin challenge was performed to diagnose aspirin hypersensitivity. Urine samples were collected on the placebo day and both before and within 2 to 4 hours after aspirin challenge for uLTE4 measurement. RESULTS: All patients with CRS had sinusitis confirmed by computed tomography. Previous ear, nose, and throat surgery was performed in 70% of the patients, NP was present in 86%, and asthma was diagnosed in 62.5%. AERD was diagnosed in 8 subjects (7 women and 1 man). Five of those patients had bronchoconstriction. At baseline, median uLTE4 was 7.5-times higher in AERD subjects than in the remaining patients. It increased almost 6-fold following the challenge, while remained unchanged in patients without aspirin hypersensitivity. Pretest uLTE4 had a sensitivity of 87.5% and specificity of 93.75% to diagnose aspirin hypersensitivity in patients with CRS. After the challenge, the values improved to 100% sensitivity and 93% specificity. CONCLUSIONS: Among CRS subjects requiring FESS, as many as 33.3% may have AERD and respond to a small provocative dose of aspirin with bronchoconstriction and/or mucosal and skin edema. A simple and inexpensive measurement of uLTE4 can help diagnose AERD in patients with CRS with sensitivity of 87.5%, but its specificity is limited and depends on the arbitrary threshold of uLTE4.
