A study of the link between gastric reflux and chronic sinusitis in adults.
Much discussion is taking place regarding the role of gastric reflux gastric reflux

We studied 31 patients in a large urban private practice who had recalcitrant chronic sinusitis chronic sinusitis Chronic sinus infection ENT Inflammation of the sinuses that empty into the nasal cavity Etiology Allergic rhinitis, nasal obstruction, deviated nasal septum, tooth abscesses, URIs despite aggressive medical and surgical therapy. After we obtained information on the severity of each patient's sinus disease, we performed either double- or triple-catheter probe pH testing to assess the presence of reflux disease. Of the 30 patients who were successfully tested (1 patient did not tolerate probe testing), 25 demonstrated reflux disease, including 2 whose reflux reached the level of the nasopharynx nasopharynx /na·so·phar·ynx/ (-far´inks) the part of the pharynx above the soft palate.nasopharyn´geal
n. . These 25 patients were placed on a proton-pump inhibitor (PP1) regimen and reassessed at least 1 month later. At follow-up, 14 of 15 evaluable patients demonstrated at least some improvement in their sinus symptoms, including 7 who experienced either a complete or almost-complete resolution of symptoms. The improvements in sinus symptoms corresponded with improvements in reflux symptoms. These findings suggest that antireflux therapy might play a role in the treatment of recalcitrant chronic sinus disease.
Inflammation of the sinuses. Acute sinusitis, usually due to infections such as the common cold, causes localized pain and tenderness, nasal obstruction and discharge, and malaise. affects almost 30 million people in the United States, and it accounts for 14.1 million office visits annually. (1) The pathophysiologic mechanism of sinusitis, as proposed by Messerklinger, is thought to begin with mild edema edema (ĭdē`mə), abnormal accumulation of fluid in the body tissues or in the body cavities causing swelling or distention of the affected parts. that leads to obstruction at the draining sinus ostia Ostia (ŏs`tēə), ancient city of Italy, at the mouth of the Tiber. It was founded (4th cent. B.C.) as a protection for Rome, then developed (from the 1st cent. B.C.) as a Roman port, rivaling Puteoli. . (2) The obstruction is believed to initiate a cycle of reactive mucosal edema that results in further occlusion of the ostia.

(5) Again in 1999, Bothwell et al demonstrated the importance of gastric reflux in the pathogenesis of chronic sinusitis in children. (6) They also reported that gastric reflux therapy was effective in the treatment of childhood chronic sinusitis.
We studied an adult population with recalcitrant chronic sinusitis that persisted despite aggressive medical and surgical therapy. Our aim was to help determine the incidence of gastric reflux in patients with sinus infections and to assess the efficacy, if any, of proton-pump inhibitor (PPI (1) (Pixels Per Inch) The measurement of the resolution of a monitor or scanner. For example, a monitor that is 16 inches wide and displays 1600 pixels across its width would have a resolution of 100 ppi (1600 divided by 16). ) therapy in alleviating any symptoms associated with sinusitis. In some reports of recent studies, investigators have continued to postulate a relationship between reflux and sinusitis. (7-9)
Patients and methods
Our study population was made up of 31 adults--24 women and 7 men, aged 26 to 68 years (mean: 43.97 [+ or -] 11.77)--who were patients in a private otolaryngology practice in a large urban area. All 31 patients had been diagnosed with chronic sinusitis based on history, physical examination, at least one postantibiotic computed tomography scan Computed tomography scan (CT scan)

Each patient had complained of recurrent sinus infections and/or chronic symptoms of sinusitis despite multiple courses of antibiotics and oral steroids.
All 31 patients were questioned about any symptoms of gastric reflux that they might have experienced, including heartburn heartburn, burning sensation beneath the breastbone, also called pyrosis.

See Nasal stuffiness. , rhinorrhea/postnasal drip, headache and/or facial pain--and they were asked to rate their smelling ability. Symptom severity was rated as absent (0), intermittent (1), or constant (2), and sense of smell was rated as excellent (0), impaired (1), or anosmic (2). The pretreatment pretreatment,

After pH testing, patients were placed on one of three PPIs: omeprazole 40 mg/day, lansoprazole 30 mg/day, or rabeprazole 20 mg/day. After a treatment period of at least 1 month, patients were contacted by telephone and asked to rate their reflux symptoms and sinusitis symptoms according to the scoring system previously described.
We used the chi-square test chi-square test: see statistics. to compare the frequency of gastric reflux in our patients with that of historical controls who did not have chronic sinusitis.
Prior to treatment, 28 of the 31 patients reported intermittent or constant nasal congestion, 27 had nasal discharge, 26 had headaches and/or facial pain facial pain,

One patient was unable to tolerate the insertion of the pH catheters, and therefore testing was not performed on her. Of the remaining 30 patients, 23 underwent triple-catheter probe pH testing and 7 underwent double-catheter testing. Of the 23 patients who underwent triple-catheter testing, reflux was detected in 20; 16 had laryngopharyngeal reflux (LPR See LPR/LPD.

gastroesophageal reflux disease
GERD ) (table 1). Of the 7 patients who underwent double-catheter testing, 2 had LPR, 3 had GERD, and 2 had no reflux (table 1). In all, some type of reflux was found in 25 of the 30 patients (83.3%) who underwent probe testing. Statistically, this rate is significantly higher than the rate of reflux in healthy controls reported by Ulualp et al (18%; p < 0.001). (4)
The 25 patients who were found to have some type of reflux were scheduled to undergo PPI therapy for at least 1 month. However, during the treatment period, 4 patients stopped taking their medication prematurely and 2 others underwent sinus surgery (table 2). Data on these 6 patients were therefore excluded from the final analysis. In addition, data on another 4 patients were excluded because we were unable to obtain follow-up information from them (table 2). In sum, data on PPI efficacy for the treatment of sinus complaints were available for 15 patients.
A comparison of the pre- and post-Tx sinus scores among the 15 evaluable patients confirms that PPI therapy did indeed alleviate sinus symptoms (figure 2). Fourteen of 15 patients experienced a reduction in their pre-Tx sinus score; 6 patients had a 1-point improvement and 8 had an improvement of 2 or more points. Five patients who had a pre-Tx sinus score of 4 or 5 improved to the point where their post-Tx score was only 1. Of 11 patients who had a pre-Tx sinus score of 4, 5, or 6, only 1 remained in that range following PPI therapy. A post-Tx sinus score of 0 or 1 was reported by 7 patients.
[FIGURE 2 OMITTED]
Patients who experienced the greatest improvement in their post-Tx sinus score also reported either a complete or nearly complete resolution of their reflux symptoms. Conversely, of 7 patients who experienced either no improvement or only a 1-point improvement in their post-Tx sinus score, only 3 reported symptomatic improvement of their reflux symptoms.
The importance of gastric reflux to the otolaryngologist has been well documented. With double-catheter pH testing, Koufman has demonstrated that gastric reflux often reaches the level of the larynx and that most of these patients are asymptomatic. (10,11) When symptoms do occur, they may not be the classic symptoms associated with GERD (e.g., heartburn, belching, and regurgitation). Instead, patients with LPR may display hoarseness, globus, chronic throat clearing, and chronic cough chronic cough,
n health condition characterized by either a lingering cough or a recurring cough lasting more than a month. . In our study, 6 of 18 patients with probe-documented LPR exhibited none of the typical symptoms of reflux.

n. testing in 1. In our study, 2 patients demonstrated significant reflux to the level of the nasopharynx on triple-catheter probe pH testing. This finding confirmed that gastric refluxate can reach as far cephalad as the nasopharynx in adults.
In the previously mentioned study by Bouchard et al, double-catheter probe pH testing showed that 40% of children with recurrent sinusitis tested positive for reflux. (3) In the study by Bothwell et al, 25 of 28 children with chronic sinusitis who had been scheduled for invasive treatment were able to avoid surgery after a course of aggressive PPI therapy. (6)
The role of reflux in initiating and maintaining sinusitis in adults is not as clear-cut as it is in children. Chambers et al suggested that the presence of reflux portends a poor symptomatic outcome after surgery for chronic sinusitis in adults, but they did not elaborate on the possible reasons why. (12) Although Ulualp et al (4) found a higher incidence of reflux in patients with sinusitis, as did we, no study has been conducted on the clinical course of patients with reflux and sinusitis who were treated with antacid therapy. We found that most adults with recalcitrant sinusitis despite conventional medical and surgical therapy responded favorably to PPI therapy, including some whose improvement was dramatic. Those patients who derived the most benefit from PPI therapy in terms of their sinus symptoms also experienced the most improvement in terms of their reflux symptoms. Even the 9 patients with environmental allergies in our study experienced significant alleviation of their sinus symptoms with control of their reflux symptoms.
Our study had several limitations. Measurements of our patients' pretreatment sense of well-being and their sinus symptoms were subjective. Furthermore, our study might have suffered from recall bias.
There is a clear need for further research into the relationship between sinusitis and reflux disease. Long-term double-blind prospective studies based on objective and validated symptom-based outcomes criteria are needed to further evaluate the efficacy of PPIs in treating recalcitrant sinusitis. Also, the presence of bilious bil·ious

2. Characterized by an excess secretion of bile.
3. reflux at the level of the larynx has been suggested by Malthaner et al (13) and by Marshall at al, (14) so the role of nonacidic gastric reflux on upper esophageal pathology should be explored, as well. In the interim, our findings suggest that reflux disease may play a role in the failure of aggressive medical therapy to resolve chronic sinusitis. Certain patients with recalcitrant sinusitis may benefit from the addition of reflux therapy to the treatment of their sinus disease.
