RESUMO

Much - possibly even too much - has been published about chemosensory dysfunction as a consequence of COVID-19. Studies have reported prevalence of taste loss in up to 89.9%, which is in a similar range as COVID-19 related smell loss. However, most of these publications rely solely on patients' self-reports. Only few studies used validated psychophysical tests to specifically address olfaction and gustation. Especially for gustation, it is evident that subjective reporting does not correlate well with more objective psychophysical findings, often leading to an overestimation of subjectively impaired taste.

RESUMO

OBJECTIVE: To analyse the correlations between olfactory psychophysical scores and the serum levels of D-dimer, C-reactive protein, ferritin, lactate dehydrogenase, procalcitonin and neutrophil-to-lymphocyte ratio in coronavirus disease 2019 patients. METHODS: Patients underwent psychophysical olfactory assessment with the Connecticut Chemosensory Clinical Research Center test, and determination of blood serum levels of the inflammatory markers D-dimer, C-reactive protein, ferritin, lactate dehydrogenase, procalcitonin and neutrophil-to-lymphocyte ratio within 10 days of the clinical onset of coronavirus disease 2019 and 60 days after. RESULTS: Seventy-seven patients were included in this study. D-dimer, procalcitonin, ferritin and neutrophil-to-lymphocyte ratio correlated significantly with severe coronavirus disease 2019. No significant correlations were found between baseline and 60-day Connecticut Chemosensory Clinical Research Center test scores and the inflammatory markers assessed. CONCLUSION: Olfactory disturbances appear to have little prognostic value in predicting the severity of coronavirus disease 2019 compared to D-dimer, ferritin, procalcitonin and neutrophil-to-lymphocyte ratio. The lack of correlation between the severity and duration of olfactory disturbances and serum levels of inflammatory markers seems to further suggest that the pathogenetic mechanisms underlying the loss of smell in coronavirus disease 2019 patients are related to local rather than systemic inflammatory factors.

RESUMO

BACKGROUND: The long-term recovery rate for coronavirus disease 2019 related chemosensory disturbances has not yet been clarified. METHODS: Olfactory and gustatory functions were assessed with psychophysical tests in patients in the first seven days from coronavirus disease 2019 onset and one, two, three and six months after the first evaluation. RESULTS: A total of 300 patients completed the study. The improvement in olfactory function was significant at the two-month follow up. At the end of the observation period, 27 per cent of the patients still experienced a persistent olfactory disturbance, including anosmia in 5 per cent of cases. As for taste, the improvement in the psychophysical scores was significant only between the baseline and the 30-day control. At the 6-month evaluation, 10 per cent of the patients presented with a persistent gustatory disturbance with an incidence of complete ageusia of 1 per cent. CONCLUSION: Six months after the onset of coronavirus disease 2019, about 6 per cent of patients still had a severe persistent olfactory or gustatory disturbance.

RESUMO

OBJECTIVE: To investigate the clinical features of patients who had two demonstrated coronavirus disease 2019 (COVID-19) episodes. METHODS: Data of patients with both COVID-19 episodes were recruited from 22 March to 27 December 2020. The following outcomes were studied: epidemiological, comorbidities, prevalence and severity of general and otolaryngological symptom, olfactory, aroma, and gustatory dysfunctions. A comparison between first and second episodes was performed. RESULTS: Forty-five patients reported having two confirmed COVID-19 episodes. The majority of patients had mild infections in both episodes. The second clinical episode was significantly similar to the first. The symptom duration of the second episode was shorter than the first. The occurrence of loss of smell was unpredictable from the first to the second episode. CONCLUSION: The recurrence of COVID-19 symptoms is associated with a similar clinical picture than the first episode in patients with initial mild-to-moderate COVID episode. The pathophysiological mechanisms underlying the development of second episode remain uncertain and may involve either true reinfection or virus reactivation from sanctuaries.

RESUMO

OBJECTIVE: To investigate prevalence and recovery of olfactory dysfunction (OD) in COVID-19 patients according to the disease severity. METHODS: From 22 March to 3 June 2020, 2581 COVID-19 patients were identified from 18 European hospitals. Epidemiological and clinical data were extracted at baseline and within the 2-month post-infection. RESULTS: The prevalence of OD was significantly higher in mild form (85.9%) compared with moderate-to-critical forms (4.5-6.9%; P = 0.001). Of the 1916 patients with OD, 1363 completed the evaluations (71.1%). A total of 328 patients (24.1%) did not subjectively recover olfaction 60 days after the onset of the dysfunction. The mean duration of self-reported OD was 21.6 ± 17.9 days. Objective olfactory evaluations identified hyposmia/anosmia in 54.7% and 36.6% of mild and moderate-to-critical forms, respectively (P = 0.001). At 60 days and 6 months, 15.3% and 4.7% of anosmic/hyposmic patients did not objectively recover olfaction, respectively. The higher baseline severity of objective olfactory evaluations was strongly predictive of persistent OD (P < 0.001). CONCLUSION: OD is more prevalent in mild COVID-19 forms than in moderate-to-critical forms. OD disappeared in 95% of patients regarding objective olfactory evaluations at 6 months.

RESUMO

BACKGROUND: The growing number of COVID-19 patients with long-lasting olfactory disorders makes it necessary to identify ef- fective treatments that enhance the spontaneous recovery of olfactory function. METHODS: Multicentre randomised case-control study that involved 18 patients with COVID-19 related anosmia or severe hyposmia for more than 30 days. Nine patients were prescribed systemic prednisone and nasal irrigation with betamethasone, ambroxol and rinazine for 15 days. The other 9, untreated, patients were used as controls. The olfactory function was evaluated with CCCRC test at 20 and 40 days from the first evaluation. RESULTS: In the control group, a median olfactory score of 20 (IQR 30) was detected at baseline. At the 20-day control there was no significant improvement in olfactory function. The improvement in olfactory performance became significant at the 40-day follow-up compared to baseline scores [60 (IQR 60) versus 20 (IQR 30)]. In the treatment group, patients had a mean olfactory score of 10 (IQR 15) at initial control. At the 20-day control, a significant im-provement in the olfactory scores, compared to the baseline, was detected [70 (IQR 40) versus 10 (IQR 15)]. Olfactory function further improved at 40 days [median score 90 (IQR 50)]. Patients in the treatment group reported significantly higher improvements of the olfactory scores than the controls at both the 20-day [40 (IQR 45) versus 10 (IQR 15)] and 40-day [60 (IQR 40) versus 30 (IQR 25)] evaluations. CONCLUSIONS: Based on the results of this study, the mix of drugs including steroids could represent a useful specific therapy to reduce the prevalence of this long-term morbidity.

RESUMO

INTRODUCTION: Loss of smell and taste is now recognised as amongst the most common symptoms of COVID-19 and the best predictor of COVID-19 positivity. Long term outcomes are unknown. This study aims to investigate recovery of loss of smell and the prevalence of parosmia. METHODOLOGY: 6-month follow-up of respondents to an online surgery who self-reported loss of smell at the onset of the CO- VID-19 pandemic in the UK. Information of additional symptoms, recovery of loss of smell and the development of parosmia was collected. RESULTS: 44% of respondents reported at least one other ongoing symptom at 6 months, of which fatigue (n=106) was the most prevalent. There was a significant improvement in self-rating of severity of olfactory loss where 177 patients stated they had a normal smell of smell while 12 patients reported complete loss of smell. The prevalence of parosmia is 43.1% with median interval of 2.5 months (range 0-6) from the onset of loss of smell. CONCLUSIONS: While many patients recover quickly, some experience long-term deficits with no self-reported improvement at 6 months. Furthermore, there is a high prevalence of parosmia even in those who report at least some recovery of olfactory func- tion. Longer term evaluation of recovery is required.

RESUMO

This review was conducted according to the Patient/problem Intervention Comparison Outcome (PICO) Statements. Some studies reported that 10-30% of patients consulting in ENT come with presenting symptoms of laryngopharyngeal reflux (LPR), but the exact prevalence of LPR is still unknown. Management has not changed in 20 years despite a significant increase in the number of publications on epidemiology, clinical presentation, diagnosis and treatment. The development of hypopharyngeal-esophageal multichannel intraluminal impedance pH monitoring (HEMII-pH) and saliva pepsin detection now allow a new multidimensional diagnostic approach associating clinical scores to HEMII-pH and saliva pepsin detection. This new approach may enable personalized treatment according to LPR profile on HEMII-pH (acid, non-acid, mixed; upright, recumbent reflux episodes). Updated treatment of LPR could consist in a 3-month association of dietary measures, proton pump inhibitors, alginate and magaldrate, followed by treatment adaptation.

RESUMO

BACKGROUND: Olfactory dysfunction represents one of the most frequent symptoms of coronavirus disease 2019, affecting about 70 per cent of patients. However, the pathogenesis of the olfactory dysfunction in coronavirus disease 2019 has not yet been elucidated. CASE REPORT: This report presents the radiological and histopathological findings of a patient who presented with anosmia persisting for more than three months after infection with severe acute respiratory syndrome coronavirus-2. CONCLUSION: The biopsy demonstrated significant disruption of the olfactory epithelium. This shifts the focus away from invasion of the olfactory bulb and encourages further studies of treatments targeted at the surface epithelium.

RESUMO

BACKGROUND: The long-term recovery rate of chemosensitive functions in coronavirus disease 2019 patients has not yet been determined. METHOD: A multicentre prospective study on 138 coronavirus disease 2019 patients was conducted. Olfactory and gustatory functions were prospectively evaluated for 60 days. RESULTS: Within the first 4 days of coronavirus disease 2019, 84.8 per cent of patients had chemosensitive dysfunction that gradually improved over the observation period. The most significant increase in chemosensitive scores occurred in the first 10 days for taste and between 10 and 20 days for smell. At the end of the observation period (60 days after symptom onset), 7.2 per cent of the patients still had severe dysfunctions. The risk of developing a long-lasting disorder becomes significant at 10 days for taste (odds ratio = 40.2, 95 per cent confidence interval = 2.204-733.2, p = 0.013) and 20 days for smell (odds ratio = 58.5, 95 per cent confidence interval = 3.278-1043.5, p = 0.005). CONCLUSION: Chemosensitive disturbances persisted in 7.2 per cent of patients 60 days after clinical onset. Specific therapies should be initiated in patients with severe olfactory and gustatory disturbances 20 days after disease onset.

RESUMO

BACKGROUND AND PURPOSE: Post-viral olfactory dysfunction is well established and has been shown to be a key symptom of COVID-19 with more than 66% of European and US patients reporting some degree of loss of smell. Persistent olfactory dysfunction appears to be commonplace and will drive the demand for general practitioner, otolaryngology or neurology consultation in the next few months - evidence regarding recovery will be essential in counselling our patients. METHODS: This was a prospective survey-based data collection and telemedicine follow-up. RESULTS: In total, 751 patients completed the study, of whom 477 were females and 274 males. The mean age of the patients was 41 ± 13 years (range 18-60). There were 621 patients (83%) who subjectively reported a total loss of smell and 130 (17%) a partial loss. After a mean follow-up of 47 ± 7 days (range 30-71) from the first consultation, 277 (37%) patients still reported a persistent subjective loss of smell, 107 (14%) reported partial recovery and 367 (49%) reported complete recovery. The mean duration of the olfactory dysfunction was 10 ± 6 days (range 3-31) in those patients who completely recovered and 12 ± 8 days (range 7-35) in those patients who partially recovered. CONCLUSIONS: According to our results, at this relatively early point in the pandemic, subjective patterns of recovery of olfactory dysfunction in COVID-19 patients are valuable for our patients, for hypothesis generation and for treatment development.

RESUMO

BACKGROUND: An objective evaluation of coronavirus disease 2019 in the first days of infection is almost impossible, as affected individuals are generally in home quarantine, and there is limited accessibility for the operator who should perform the test. To overcome this limitation, a recently validated psychophysical self-administered test was used, which can be performed remotely in the assessment of early-stage coronavirus disease 2019 patients. METHODS: Olfactory and gustatory functions were objectively assessed in 300 patients in the first 7 days from coronavirus disease 2019 symptom onset. RESULTS: Seventy per cent of the patients presented olfactory and/or gustatory disorders. The dysfunctions detected were mainly complete anosmia (47 per cent) or ageusia (38 per cent). A significant correlation was found between taste dysfunction and female gender (odds ratio = 1.936, p = 0.014) and fever (odds ratio = 2.132, p = 0.003). CONCLUSION: The psychophysical evaluation protocol proposed is an effective tool for the fast and objective evaluation of patients in the early stages of coronavirus disease 2019. Chemosensitive disorders have been confirmed to be frequent and early symptoms of the coronavirus infection, and, in a significant number of cases, they are the first or only manifestation of coronavirus disease 2019.

RESUMO

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is being intensively studied, particularly its evolution, in the increasingly available sequences between countries/continents with classical phylogenetic tree representation. More recently, certain protein mutations have been correlated with specific functional impacts. Our clinical data from patients suggest that clinical symptoms differ between European countries. Among other factors, SARS-CoV-2 mutations could explain these disparities. Our analyses point to an association of diverse mutations, including co-evolving ones, in a few SARS-CoV-2 proteins within specific countries. We therefore suggest combining clinical information from patients and the determination of the associated SARS-CoV-2 genome to better understand the specific symptoms.

RESUMO

Since the outbreak of the pandemic, anecdotal observations have been accumulating rapidly that sudden anosmia and dysgeusia are peculiar symptoms associated with the COVID-19 infection. Prof C. Hopkins, as President of British Rhinological Society, published a letter describing "the loss of sense of smell as a marker of COVID-19 infection" and proposed that adults presenting with anosmia but no other symptoms should self-isolate for seven days. The Hopkins team published the first case report and case series as well as other evidence that isolated sudden onset anosmia (ISOA), should be considered highly suspicious for SARS-CoV-2(1). Subsequently, a larger series of 2428 patients presenting with new onset anosmia during the COVID-19 pandemic has been reported, of whom 16% report loss of sense of smell as an isolated symptom. Only 51% reported the recognized symptoms of cough or fever. A major limitation of this series however, was a lack of access to testing to confirm the COVID-19 status of the patients(2); in the 80 who had been tested 74% were positive. In the same way, the American Academy of Otolaryngology-head and neck surgery (AA0-HNS) proposed "that anosmia could be added to the list of screening tools for possible COVID-19 infection. More, they warrant serious consideration for self-isolation and testing those patients".

RESUMO

INTRODUCTION: To analyze the epidemiological characteristics of placebo controlled randomized trials (RCTs) that evaluated the effectiveness of medical treatments over placebo in laryngopharyngeal reflux (LPR). MATERIAL AND METHODS: PubMed, Cochrane database, and Scopus were assessed for subject headings using the PRISMA recommendations. Placebo RCTs published between 1990 and 2018 describing clinical evolution throughout LPR treatment were extracted and analyzed for evidence-based level, number of patients, inclusion and exclusion criteria, gender, age, symptoms and signs used as therapeutic outcomes, and treatment schemes. RESULTS: The database search identified 15 placebo RCTs with a total of 763 patients. The mean age of patients was 48.59 years and 52.68% of patients were female. Among the 15 placebo RCTs, 9 have demonstrated a partial or total superiority of a medical treatment over placebo. Most of authors based the LPR diagnosis on symptoms and signs without additional examination. Our analysis reveals an important heterogeneity between studies with regard to the diagnosis criteria, treatment schemes and signs and symptoms used as therapeutic outcomes. Many commonly reported signs and symptoms related to LPR were not used as therapeutic outcomes. Half of the authors did not prescribe diet and behavioral changes along the treatment. CONCLUSION: The controversy in the RCTs about the superiority of medical treatment over placebo in LPR disease is probably due to discrepancies in the diagnosis method, exclusion criteria, therapeutic schemes and the lack of comprehensive tools for the assessment of signs and symptoms. In this context, the LPR Study Group of Young-Otolaryngologists of the International Federations of Oto-Rhino-Laryngological Societies developed two new instruments to precisely assess signs and symptoms throughout the treatment. These two instruments could be used in future trials comparing medical treatment over placebo in LPR disease.

RESUMO

OBJECTIVE: To assess the usefulness of voice quality measurements as a treatment outcome in patients with laryngopharyngeal reflux (LPR)-related symptoms. DESIGN: Prospective uncontrolled multi-centre study. MATERIAL AND METHODS: A total of 80 clinically diagnosed LPR patients with a reflux finding score (RFS)>7 and a reflux symptom index (RSI)>13 were treated with pantoprazole and diet recommendations during 3 or 6 months, according to their evolution. RSI; RFS; blinded Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI) and aerodynamic and acoustic measurements were evaluated at baseline, 3 months (n = 80), and 6 months (n = 41) post-treatment. We conducted a correlation analysis between the adherence to the diet, and the evolution of both signs and symptoms and between videolaryngostroboscopic signs and acoustic measurements. RESULTS: Reflux symptom index, RFS, perceptual voice quality evaluations (dysphonia, roughness, strain and instability), and aerodynamic and acoustic measurements (ie, percent jitter and percent shimmer) were significantly improved at 3 months post-treatment but not at 6 months. Percent jitter was the most useful outcome for evaluating the clinical evolution of patients throughout the treatment course. A significant relationship between globus sensation and posterior commissure hypertrophy was documented; both seemed to significantly improve from 3 to 6 months. The correlation analysis revealed correlations between adherence to diet recommendations and the improvement of symptoms and between posterior commissure granulation severity and acoustic measurement impairments. CONCLUSION: Voice quality improved in a manner similar to both signs and symptoms throughout a 6-month empirical treatment with better improvement the 3 first months. Voice quality assessments can be used as indicators of treatment effectiveness in patients with LPR-related symptoms.
