Comparison of prevalence and evolution of COVID-19 olfactory disorders in patients infected by D614 (wild) and B.1.1.7. Alpha variant: a brief report.

OBJECTIVES: To investigate the prevalence and the evolution of olfactory disorders (OD) related to coronavirus disease 2019 (COVID-19) in patients infected during the first and the second European waves. METHODS: From March 2020 to October 2020, COVID-19 patients with OD were recruited and followed over the 12-month post-infection. The following data were collected: demographic, treatments, vaccination status, and olfactory function. Olfaction was assessed with the Olfactory Disorder Questionnaire (ODQ), and threshold, discrimination, and identification (TDI) test. Outcomes were compared between patients of the first wave (group 1: wild/D614G virus) and the second wave (group 2: B.1.1.7. Alpha variant) at 1-, 3- and 12-month post-infection. RESULTS: Sixty patients completed the evaluations accounting for 33 and 27 patients in group 1 and 2, respectively. The 1-month TDI score (23.7 ± 5.3) was significantly lower in group 2 compared to group 1 (29.8 ± 8.7; p = 0.017). Proportion of normosmic patients at 1-month post-infection was significantly higher in group 1 compared to group 2 (p = 0.009). TDI scores only significantly increased from 1- to 3-month post-infection in anosmic and hyposmic patients. Focusing on There was a negative association between the 1-month ODQ and the 1-month TDI (rs = - 0.493; p = 0.012). ODQ was a significant predictor of TDI scores at 3- and 12-month post-infection. The 12-month prevalence of parosmia was 60.6% in group 1 and 42.4% in group 2, respectively. There was no significant influence of oral corticosteroid treatment, adherence to an olfactory training and vaccination status on the olfactory outcomes. CONCLUSIONS: Patients of the second wave (Alpha B.1.1.7. variant) reported significant higher proportion of psychophysical test abnormalities at 1-month post-infection than patients infected during the first wave (D614G virus).

Laryngopharyngeal Reflux Patient Changes during the COVID-19 Quarantine.

Background and Objective: To examine the effects of the lockdown on diet adherence and stress levels in patients with laryngopharyngeal reflux (LPR). Materials and Methods: Patients with a positive LPR diagnosis at the hypopharyngeal-esophageal impedance-pH monitoring were treated from a pre- to lockdown period with a 3-month high-protein, low-fat, alkaline, plant-based diet, with behavioral changes, and an association of pantoprazole (20 MG/d) and alginate (Gaviscon 3/d). The following patient-reported outcomes questionnaire and findings instrument were used: Reflux Symptom Score-12 (RSS-12) and Reflux Sign Assessment (RSA). At the posttreatment time, patients were invited to evaluate the impact of lockdown on diet adherence and stress management with a predefined grid of foods and beverages and the perceived stress scale (PSS), respectively. Results: Thirty-two patients completed the evaluations. RSS-12 and RSA significantly improved from baseline to 3-month posttreatment. Most patients experienced mild-to-severe stress levels at the end of the lockdown. The level of stress substantially increased in 11 patients (34%) due to the lockdown, while it did not change in 11 patients (44%). In 11 cases (34%), patients reported that the adherence to the anti-reflux diet was better than initially presumed thanks to the lockdown period, while 44% (N = 14) reported that the lockdown did not impact the adherence to a diet. PSS and RSS-12 were significantly correlated at the end of the pandemic (rs = 0.681; p < 0.001). The increase in stress level was positively associated with the lack of adherence to diet (rs = 0.367; p = 0.039). Conclusions: During the lockdown, the diet habits of LPR patients were improved in one-third and unchanged in 44% of cases. The stress level was increased in one-third of patients, which was associated with an increase in symptom scores.

Effectiveness and safety of PRP on persistent olfactory dysfunction related to COVID-19.

INTRODUCTION: Olfactory dysfunction (OD) is a well know symptom of coronavirus disease 2019 (COVID-19), accounting for 48 to 85% of patients. In 1 to 10% of cases, patients develop a chronic olfactory dysfunction (COD), lasting more than 6 months. Recently, platelet-rich plasma (PRP) was used in patients with non-COVID-19 COD and authors reported encouraging results. METHODS: In the present study, we investigated the usefulness and safety of PRP injection in 56 patients with COVID-19 COD by the Sniffing Stick test (TDI score) and a linker-scale from 0 (none) to 3 (strong) and we compare the result to a control group. RESULTS: At 1 month post-PRP injection, the mean TDI scores significantly improved by 6.7 points in the PRP group (p < 0,001), the mean self-assessment of improvement in smell function was 1.8 (mild-to-moderate) in the PRP group, which was significantly higher than the score (0.3) in the control group (p < 0,001). CONCLUSION: Our results showed that PRP in the olfactory cleft can increase the olfactory threshold 1 month after the injection. Moreover, our results suggest that timing of treatment may be an important factor and that PRP is a safe treatment, because no adverse effects were reported throughout the study. TRIAL REGISTRATION NUMBER: NCT05226546.

Efficacy and safety of oral corticosteroids and olfactory training in the management of COVID-19-related loss of smell.

PURPOSE: As the COVID-19 pandemic continues, an increasing number of patients are afflicted by olfactory loss, a now well-recognized symptom of the disease. Though many patients seem to recover their sense of smell after a few weeks, a certain proportion of them seem to develop long-lasting olfactory disorder. Yet, as of October 2020, there is no recommended standardized treatment to reduce the risk of developing long-term olfactory disorder. In this pilot study, we investigated the efficacy and the safety of oral corticosteroids and olfactory training as a treatment for patients with persistent olfactory dysfunction as a result of COVID-19. METHODS: Non-hospitalized patients with a sudden loss of smell and a confirmed COVID-19 diagnosis were recruited by hospital call from February to April 2020. These participants were submitted to an extensive psychophysical testing in order to identify those with persistent dysosmia. Dysosmic patients were then treated either by a 10-day course of oral corticosteroids combined with olfactory training, or by olfactory training alone. All participants were subject to a second olfactory test after a mean of 10 weeks. RESULTS: 72 subjects with documented COVID-19 infection performed the initial olfactory test, on average 5 weeks after losing their sense of smell. Amongst them, 27 (37.5%) patients showed persistent dysosmia and were all included in this study. Nine participants received oral corticosteroids and performed olfactory training (OCS + OT), while 18 performed olfactory training (OT) only. Only participants in the OCS + OT group had significantly improved their olfactory score and did so above the minimal clinically important difference for subjective improvement of smell (p = 0.007). Three of the participants who received oral corticosteroids reported minimal and transient side effects. CONCLUSION: This pilot study may suggest the combination of a short course of oral corticosteroids and olfactory training is safe and may be beneficial in helping patients with enduring dysosmia recover from olfactory loss due to COVID-19. There is a crucial need for further investigation with larger cohorts to corroborate these findings.

Psychophysical evaluation of chemosensory functions 5 weeks after olfactory loss due to COVID-19: a prospective cohort study on 72 patients.

PURPOSE: To evaluate the evolution of chemosensation via extended psychophysical testing in patients who suffered from sudden chemosensory loss due to coronavirus disease 2019 (COVID-19). Additionally, this study sought to determine whether odor threshold testing provided additional information on olfactory loss due to COVID-19 compared to the more common odor identification testing. METHODS: Prospective cohort study of patients with sudden chemosensory loss since February 2020 and confirmed COVID-19 infection via RT-PCR or serology testing. Olfactory function was tested extensively using the "Sniffin Sticks" test battery. In addition, we screened gustatory perception and nasal cooling sensations using psychophysical tests. RESULTS: Seventy-two patients completed the study. After a mean of 37 days, 37% of patients showed olfactory dysfunction, 7% were dysgeusic, and 48% showed signs of low sensitivity for cooling sensation. A longer duration of anosmia before smell improvement was correlated with lower olfactory function at 5 weeks. Odor threshold detection was more affected by COVID-19 compared to odor identification. CONCLUSION: Five weeks after developing sudden chemosensory loss due to COVID-19, a high proportion of patients were dysosmic and showed signs of low nasal cooling sensitivity, whereas most of them had normal taste function. SARS-CoV-2 affected mainly odor thresholds, possibly suggesting that the major cause of loss of smell lies at the level of the olfactory neuroepithelium, rather than in the central nervous system.

The efficacy of a personalised treatment depending on the characteristics of reflux at multichannel intraluminal impedance-pH monitoring in patients with acid, non-acid and mixed laryngopharyngeal reflux.

OBJECTIVE: To assess the evolution of symptoms and findings of laryngopharyngeal reflux (LPR) patients according to the type of reflux (acid, non-acid, mixed and gastro-oesophageal (GERD)). DESIGN: Prospective uncontrolled multicentre study. METHODS: One hundred and six patients with LPR have been recruited from 3 European Hospitals. According to the reflux characteristics at the impedance-pH monitoring (acid, non-acid, mixed, GERD), patients received a personalised treatment based on the association of diet, pantoprazole, alginate or magaldrate for 3 months. Reflux Symptom Score (RSS) was assessed at baseline, 6 and 12 weeks post-treatment. Reflux Sign Assessment (RSA) has been used to rate laryngeal and extra-laryngeal findings at baseline and 12 weeks post-treatment. Overall success rate and the evolution of symptoms and findings were evaluated according to the LPR types. RESULTS: One hundred and two LPR patients (42 acid, 33 non-acid, 27 mixed, including 49 with LPR and GERD) completed the study. RSS and RSA total scores significantly improved from baseline to post-treatment time in acid, mixed and non-acid groups. The presence of GERD in addition to LPR did not impact the clinical improvement. The 3-month success rates of treatment ranged from 62% to 64%, and there were no significant differences between groups. The success rate of patients with non-acid LPR was similar to those of patients with mixed and acid LPR. CONCLUSION: MII-pH is useful to specify the type of LPR and the related most adequate therapeutic regimen. Non-acid or mixed LPR similarly respond to treatment than acid LPR but require a treatment based on alginate or magaldrate covering the non-acid proximal reflux events.

Clinical and epidemiological characteristics of 1420 European patients with mild-to-moderate coronavirus disease 2019.

BACKGROUND: The clinical presentation of European patients with mild-to-moderate COVID-19 infection is still unknown. OBJECTIVE: To study the clinical presentation of COVID-19 in Europe. METHODS: Patients with positive diagnosis of COVID-19 were recruited from 18 European hospitals. Epidemiological and clinical data were obtained through a standardized questionnaire. Bayesian analysis was used for analysing the relationship between outcomes. RESULTS: A total of 1,420 patients completed the study (962 females, 30.7% of healthcare workers). The mean age of patients was 39.17 ± 12.09 years. The most common symptoms were headache (70.3%), loss of smell (70.2%), nasal obstruction (67.8%), cough (63.2%), asthenia (63.3%), myalgia (62.5%), rhinorrhea (60.1%), gustatory dysfunction (54.2%) and sore throat (52.9%). Fever was reported by 45.4%. The mean duration of COVID-19 symptoms of mild-to-moderate cured patients was 11.5 ± 5.7 days. The prevalence of symptoms significantly varied according to age and sex. Young patients more frequently had ear, nose and throat complaints, whereas elderly individuals often presented fever, fatigue and loss of appetite. Loss of smell, headache, nasal obstruction and fatigue were more prevalent in female patients. The loss of smell was a key symptom of mild-to-moderate COVID-19 patients and was not associated with nasal obstruction and rhinorrhea. Loss of smell persisted at least 7 days after the disease in 37.5% of cured patients. CONCLUSION: The clinical presentation of mild-to-moderate COVID-19 substantially varies according to the age and the sex characteristics of patients. Olfactory dysfunction seems to be an important underestimated symptom of mild-to-moderate COVID-19 that needs to be recognized as such by the WHO.

Chondrolaryngoplasty for transgender patients: feasibility of a scar-free approach.

PURPOSE: Adult male-to-female transgender patients with a prominent thyroid notch can benefit from chondrolaryngoplasty with high satisfaction rates. It is a safe, effective, and established procedure with only minor and temporary complications. Until now, only external approaches have been described, leaving the patient with a cervical scar, which remains a frequent complaint. The goal of this study is to assess the feasibility of a transvestibular endoscopic chondrolaryngoplasty. METHODS: Transvestibular endoscopic chondrolaryngoplasty was conducted on six fresh adult male cadavers. The thyroid cartilage approach was similar to the one described in cases of transvestibular endoscopic thyroidectomy. After thyroid notch exposition, the laryngeal prominence was shaved down using an endoscopic burr until the desired aesthetic result was achieved. RESULTS: Laryngeal prominence volume was significantly reduced without any cutaneous scar. CONCLUSION: We have demonstrated that this novel approach is feasible and has the advantage of leaving the patient's neck scar-free.

Patients with acid, high-fat and low-protein diet have higher laryngopharyngeal reflux episodes at the impedance-pH monitoring.

OBJECTIVE: To assess the impact of diet on the occurrence of proximal reflux episodes at the multichannel intraluminal impedance-pH monitoring (MII-pH) in patients with laryngopharyngeal reflux (LPR). METHODS: Patients with LPR symptoms and findings were recruited from three European hospitals. The LPR diagnostic was confirmed through MII-pH and patients were benefited from gastrointestinal (GI) endoscopy. Regarding the types of reflux at the MII-pH (acid, nonacid, mixed), patients received a 3 month-therapy based on the association of alkaline, low-fat and high-protein diet, proton pump inhibitors, alginate or magaldrate. Reflux symptom score (RSS) and reflux sign assessment (RSA) were used to evaluate laryngeal and extra-laryngeal symptoms and findings from pretreatment to posttreatment. The Global Refluxogenic Score (GRES) was used to assess the refluxogenic potential of the diet of the patients at baseline and posttreatment. The relationship between GRES severity; the MII-pH findings; GI endoscopy; and the therapeutic response was explored through multiple linear regression. RESULTS: Eighty-five LPR patients were included. The mean GRES significantly improved from pretreatment (50.7 ± 23.8) to posttreatment (27.3 ± 23.2; P = 0.001). Similarly, RSS and RSA significantly improved from baseline to posttreatment. The baseline GRES was significantly associated with the occurrence of proximal reflux episodes at the MII-pH (P = 0.001). Trends were found regarding the association between GRES and the occurrence of esophagitis (P = 0.06) and between hiatal hernia and DeMeester score (P = 0.06). There was a significant and strong association between the concomitant respect of diet and medication and the improvement of RSS (P = 0.001). CONCLUSION: The consumption of high-fat, low-protein, high-sugar, acid foods, and beverages is associated with a higher number of proximal reflux episodes at the MII-pH, according to the global refluxogenic score of LPR patients.

Olfactory and gustatory dysfunctions as a clinical presentation of mild-to-moderate forms of the coronavirus disease (COVID-19): a multicenter European study.

OBJECTIVE: To investigate the occurrence of olfactory and gustatory dysfunctions in patients with laboratory-confirmed COVID-19 infection. METHODS: Patients with laboratory-confirmed COVID-19 infection were recruited from 12 European hospitals. The following epidemiological and clinical outcomes have been studied: age, sex, ethnicity, comorbidities, and general and otolaryngological symptoms. Patients completed olfactory and gustatory questionnaires based on the smell and taste component of the National Health and Nutrition Examination Survey, and the short version of the Questionnaire of Olfactory Disorders-Negative Statements (sQOD-NS). RESULTS: A total of 417 mild-to-moderate COVID-19 patients completed the study (263 females). The most prevalent general symptoms consisted of cough, myalgia, and loss of appetite. Face pain and nasal obstruction were the most disease-related otolaryngological symptoms. 85.6% and 88.0% of patients reported olfactory and gustatory dysfunctions, respectively. There was a significant association between both disorders (p < 0.001). Olfactory dysfunction (OD) appeared before the other symptoms in 11.8% of cases. The sQO-NS scores were significantly lower in patients with anosmia compared with normosmic or hyposmic individuals (p = 0.001). Among the 18.2% of patients without nasal obstruction or rhinorrhea, 79.7% were hyposmic or anosmic. The early olfactory recovery rate was 44.0%. Females were significantly more affected by olfactory and gustatory dysfunctions than males (p = 0.001). CONCLUSION: Olfactory and gustatory disorders are prevalent symptoms in European COVID-19 patients, who may not have nasal symptoms. The sudden anosmia or ageusia need to be recognized by the international scientific community as important symptoms of the COVID-19 infection.

Chronic maxillary atelectasis and silent sinus syndrome: two faces of the same clinical entity.

Chronic maxillary atelectasis (CMA) and silent sinus syndrome (SSS) are rare clinical entities characterized by an implosion of the maxillary sinus that may or may not be associated with sinonasal symptoms, and are complicated by ipsilateral enophthalmos. The objective of this article is to discuss the definitions, physiopathology, clinical and radiographic characteristics, and surgical management of these entities. We retrospectively reviewed 18 patients (7 women, 11 men, aged 12-70 years) diagnosed and treated in the ear, nose, and throat departments of four Belgian teaching hospitals between 2000 and 2015. Nine patients had a history of sinus disease. In all cases, a computed tomography scan showed downward displacement of the orbital floor, increased orbital volume, and maxillary sinus contraction. Five patients met the criteria for grade II CMA and 13 for grade III CMA. Four patients met the criteria for SSS. All patients underwent wide endoscopic middle maxillary antrostomy. There were no orbital complications and all patients experienced resolution or a dramatic reduction of their symptomatology. Only one patient asked for an orbital floor reconstruction to correct a persisting cosmetic deformity. Although CMA and SSS are usually regarded as different entities in the literature, we believe that they lie on the same clinical spectrum. Treatment for both conditions is similar, i.e., middle meatal antrostomy to halt or even reverse the pathological evolution and reconstruction of the orbital floor in the event of persistent cosmetic deformity.

Congenital Nasal Pyriform Aperture Stenosis in Association With Polymalformative Syndrome of the Midline.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare neonatal entity characterized by a reduction in the pyriform orifice of the nasal cavity. Because of its nonspecific clinical presentation as respiratory distress symptoms, it can mimic choanal atresia. Although isolated forms have been described, CNPAS is often associated with other congenital midline malformations. A single median incisor is usually found, with or without other cervical and maxillofacial malformations. The existence of hypothalamic-pituitary axis malformations with endocrine disorders is also possible and, in some cases, a moderate to severe intellectual deficit in association with other brain malformations. Radiological investigation is a central point in the multidisciplinary management of this type of polymalformative syndrome.

Impact of COVID-19 Lockdown on Stress and Diet Adherence in Patients with Laryngopharyngeal Reflux.

Objectives:To study the impact of lockdown on diet adherence and stress in patients treated for laryngopharyngeal reflux (LPR). Methods:Patients with a positive LPR diagnosis at the hypopharyngeal-esophageal impedance-pH monitoring were treated from the pre- to lockdown period with diet, behavioral changes and an association of proton pump inhibitors and alginate. The following outcomes were used to assess the clinical features of patients: reflux symptom score-12 (RSS-12) and reflux sign assessment (RSA). At post-treatment time, patients were invited to evaluate the impact of lockdown on diet adherence and stress management with a predefined grid of foods and beverages and perceived stress scale (PSS), respectively. Results:Thirty-two patients completed the evaluations. RSS-12 and RSA significantly improved from baseline to three-month post-treatment. Most patients experienced mild-to-severe stress level at the end of the lockdown. The level of stress substantially increased in 34% of patients due to lockdown, while it did not change in 44%. In 34% of cases, patients reported that adherence to antireflux diet was better than initially presumed thanks to the lockdown period, while 44% believed that the lockdown did not impact their adherence to diet. PSS and RSS-12 were significantly correlated at the end of the pandemic (p<0.001). The increase of stress level was positively associated with the lack of adherence to diet (p=0.039). Conclusion:During the lockdown, diet habits were improved or unchanged in most LPR cases, while stress level was increased in one-third of patients.

Papillary Thyroid Carcinoma Metastatic to the Frontal Sinus and Frontal Recess: Case Report.

We describe an extremely rare papillary thyroid carcinoma metastasic to the paranasal sinuses and our surgical management. A 39-year-old patient with a history of papillary thyroid carcinoma diagnosed five years earlier who presented with symptoms of chronic sinusitis. Medical imaging demonstrated opacification of the frontal sinuses and the anterior ethmoid sinus without signs of angiogenesis, bone destruction or calcification. Biopsy under general anesthesia revealed presence of papillary thyroid carcinoma cells. Treatment consisted in sinus endoscopic surgery with Draf III procedure followed by 131I therapy. To our best knowledge, this is the first described case of papillary thyroid carcinoma metastatic to the frontal sinus and frontal recess.

Influence of Age and Sex on Clinical and Therapeutic Features of Laryngopharyngeal Reflux.

OBJECTIVE: To explore the influence of age and sex on the clinical presentation and therapeutic response of patients with laryngopharyngeal reflux (LPR). STUDY DESIGN: Prospective study. SETTING: Prospective multicenter study of 271 patients with a diagnosis of LPR confirmed by impedance-pH monitoring. METHODS: Patients were prescribed 6 months of diet changes and a combination of pantoprazole and/or alginate depending on the results of their impedance-pH results. The Reflux Symptom Score (RSS) and Reflux Sign Assessment (RSA) were collected at baseline and at 3 and 6 months posttreatment. Data were explored according to sex and age. RESULTS: A total of 237 patients completed the evaluations (138 females). On the RSS, patients of the oldest group (>60 years) had lower symptom scores (throat pain, ear pain, odynophagia, chest pain, tongue burning, nausea, halitosis, and indigestion) and lower quality-of-life scores than younger individuals. RSS and RSA outcomes significantly improved from pretreatment to 3 months posttreatment in all groups. Scores on the RSS and RSA continued to improve from 3 to 6 months posttreatment in the elderly group. Females with LPR had a higher score on the RSS at baseline as compared with males. On the RSS, scores significantly improved after 3 months in males and females; however, they continued to improve from 3 to 6 months in the female group. CONCLUSION: Age and sex may influence the clinical presentation and pre- to posttreatment evolution of symptoms and findings. Age and sex differences could be considered in future therapeutic approaches to guide more effective personalized treatment plans for patients with LPR.

Features of Mild-to-Moderate COVID-19 Patients With Dysphonia.

INTRODUCTION: To explore the prevalence of dysphonia in European patients with mild-to-moderate COVID-19 and the clinical features of dysphonic patients. METHODS: The clinical and epidemiological data of 702 patients with mild-to-moderate COVID-19 were collected from 19 European Hospitals. The following data were extracted: age, sex, ethnicity, tobacco consumption, comorbidities, general, and otolaryngological symptoms. Dysphonia and otolaryngological symptoms were self-assessed through a 4-point scale. The prevalence of dysphonia, as part of the COVID-19 symptoms, was assessed. The outcomes were compared between dysphonic and nondysphonic patients. The association between dysphonia severity and outcomes was studied through Bayesian analysis. RESULTS: A total of 188 patients were dysphonic, accounting for 26.8% of cases. Females developed more frequently dysphonia than males (P = 0.022). The proportion of smokers was significantly higher in the dysphonic group (P = 0.042). The prevalence of the following symptoms was higher in dysphonic patients compared with nondysphonic patients: cough, chest pain, sticky sputum, arthralgia, diarrhea, headache, fatigue, nausea, and vomiting. The severity of dyspnea, dysphagia, ear pain, face pain, throat pain, and nasal obstruction was higher in dysphonic group compared with nondysphonic group. There were significant associations between the severity of dysphonia, dysphagia, and cough. CONCLUSION: Dysphonia may be encountered in a quarter of patients with mild-to-moderate COVID-19 and should be considered as a symptom list of the infection. Dysphonic COVID-19 patients are more symptomatic than nondysphonic individuals. Future studies are needed to investigate the relevance of dysphonia in the COVID-19 clinical presentation.

Saliva Pepsin Concentration of Laryngopharyngeal Reflux Patients Is Influenced by Meals Consumed Before the Samples.

OBJECTIVES/HYPOTHESIS: To assess the impact of diet on the saliva pepsin concentration of patients with laryngopharyngeal reflux (LPR). STUDY DESIGN: Non-controlled Prospective Study. METHODS: Patients with positive LPR regarding hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH) were enrolled from three European Hospitals. Patients collected three saliva samples, respectively, in the morning (fasting), and 1 to 2 hour after lunch and dinner. Patients carefully detailed foods and beverages consumed during meals and before the pepsin samples. The 3-month treatment was based on the association of diet, proton pump inhibitors, alginate, or magaldrate regarding the HEMII-pH characteristics. Reflux Symptom Score (RSS) and Reflux Sign Assessment (RSA) were used for assessing the pre- to posttreatment clinical evolution. The Refluxogenic Diet Score and the Refluxogenic Score of a Dish (RESDI) were used to assess the refluxogenic potential of foods and beverages. The relationship between saliva pepsin concentration, HEMII-pH, RESDI, RSS, and RSA was investigated through multiple linear regression. RESULTS: Forty-two patients were included. The saliva pepsin concentration of the 24-hour period of testing was significantly associated with foods and beverages consumed during the testing period and the evening dinner (rs = 0.973, P < .001). RSS and RSA significantly improved throughout treatment. The level of saliva pepsin in the morning was a negative predictive factor of the therapeutic response regarding RSA and RSS (P < .036). CONCLUSIONS: Foods and beverages may significantly impact the saliva pepsin concentration of patients with LPR. Patients with high-level saliva pepsin in the morning had lower therapeutic response compared with those with low-level saliva pepsin. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:350-359, 2021.

A 10-Year Follow-Up of a Randomized Prospective Study of 2 Treatments for Chronic Rhinosinusitis Without Nasal Polyps and Investigation of the Impact of Gastroeosophageal Reflux Disease in the Resistance to Treatment.

OBJECTIVES: To compare the 2 long-term medical strategies in chronic rhinosinusitis without nasal polyps (CRSnNP) and to identify the role of gastroesophageal reflux disease (GERD) and Helicobacter pylori as factors of treatment failure. MATERIAL AND METHODS: Fifty-seven patients with CRSnNP were randomized into 2 therapeutic groups. The first group was treated with 4 weeks of amoxicillin/clavulanate and a short course of oral steroids. The second group received 8 weeks of clarithromycin. Sinonasal Outcome Test-20 (SNOT-20) and Lund and Mackay scores were assessed at baseline and after treatment, and GERD Health-Related Quality of Life (GERD-HRQL) questionnaire was evaluated in all patients. Patients with a GERD-HRQL score >8 received esogastroscopy and H pylori detection. Patients were followed during a 10-year period for clinical course and GERD evolution. The 10-year evolution of patients was described in terms of recurrence, medical, and surgical treatments. RESULTS: Thirty-seven patients completed the study; SNOT-20 and Lund and Mackay scores similarly improved in both groups. Amoxicillin/clavulanate group had significantly more adverse reactions than the clarithromycin group (P = .03). After the therapeutic course, 35% (amoxicillin/clavulanate) and 41% (clarithromycin) of patients needed functional endoscopic sinus surgery (FESS). During the long-term follow-up, 54% (amoxicillin/clavulanate) and 40% (clarithromycin) of patients had late CRSnNP recurrence; FESS was performed in less than 15% of cases of recurrence. Gastroesophageal reflux disease complaint's severity was associated with late recurrence of CRSnNP. CONCLUSION: Amoxicillin/clavulanate and clarithromycin would be competitive treatments for CRSnNP. Gastroesophageal reflux disease seems to be a negative factor for treatment response and recurrence.

Hypopharyngeal-Esophageal Impedance-pH Monitoring Profiles of Laryngopharyngeal Reflux Patients.

OBJECTIVES/HYPOTHESIS: To investigate the profile of patients with laryngopharyngeal reflux (LPR) at hypopharyngeal-esophageal multichannel intraluminal impedance-pH (HEMII-pH) monitoring and the relationship between hypopharyngeal-proximal reflux episodes (HREs) and saliva pepsin concentration. STUDY DESIGN: Prospective non-controlled. METHODS: Patients were recruited from three European hospitals from January 2018 to October 2019. Patients benefited from HEMII-pH monitoring and saliva collections to measure saliva pepsin concentration in the same time. Saliva pepsin concentration was measured in the morning (fasting), after lunch, and after dinner. The LPR profile of patients was studied through a breakdown of the HEMII-pH findings over the 24 hours of testing. The relationship between the concentrations of saliva pepsin and 24-hour HREs was studied through linear multiple regression. RESULTS: One hundred twenty-six patients completed the study. The HEMII-pH analyses revealed that 73.99% of HREs occurred outside 1-hour postmeal times, whereas 20.49% and 5.52% of HREs occurred during the 1-hour postmeal and nighttime, respectively. Seventy-four patients (58.73%) did not have nighttime HREs. Patients with both daytime and nighttime HREs had more severe HEMII-pH parameters and reflux symptom score compared with patients with only daytime HREs. There were no significant associations between HREs and saliva pepsin concentration. CONCLUSIONS: Unlike gastroesophageal reflux disease, HREs occur less frequently after meals and nighttime. The analysis of the HEMII-pH profile of the LPR patients has to be considered to develop future personalized therapeutic strategies. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:268-276, 2021.
