COVID-19 SYMPTOMS AND DISEASE COURSE IN GERMAN PEDIATRIC RHEUMATOLOGY PATIENTS REPORTED TO BIKER

BackgroundCOVID-19 has shaped the world over the last 3 years. Although the risk for severe COVID-19 progression in children is low it might be aggravated by chronic rheumatic disease or treatment with immunosuppressive drugs.ObjectivesWe analyzed clinical data of COVID-19 cases among paediatric patients with rheumatic diseases reported to BIKER between March 2020 and December 2022.MethodsThe main task of the German BIKER (Biologics in Pediatric Rheumatology) registry is safety monitoring of biologic therapies in JIA. After the onset of the COVID-19 pandemic, the survey was expanded with a standardized form to proactively interview all participating centers about occurrence, presentation and outcome of SARS-CoV-2 infections in children with rheumatic diseases.ResultsA total of 68 centres participated in the survey. Clinical data from 928 COVID infections in 885 patients with rheumatic diseases could be analyzed. JIA was the most common diagnosis with (717 infections), followed by genetic autoinflammation (103 infections), systemic autoimmune diseases (78 infections), idiopathic uveitis (n=25), vasculitis (n=5).In 374 reported COVID infections (40%), patients were receiving conventional DMARDs, in 331 (36%) biologics, mainly TNF inhibitors (TNFi, n=241 (26%)). In 567 reports (61%) patients used either a biologic or a DMARD, in 339 reports patients (37%) did not use any antirheumatic medication including steroid.Over the last 3 years, COVID-19 occurred in Germany in 5 distinguishable waves, calendar weeks (CW) 10-30 in 2020, CW 21/2020 – 8/2021(both predominantly wild-type variant), CW 9-27 in 2021 (Alpha variant in the majority of infections), CW 28-51 in 2021 (Delta variant), since CW 52/2021 (several Omikron variants;Robert-Koch Institute: VOC_VOI_Tabelle.xlsx;live.com))In our cohort, patients with SARS-CoV-2 infection were slightly older during the 1st and 2nd wave (mean age 12.7+/-3.5 and 12.8+/-4.3 years) compared to the 4th and 5th wave with 11.4+/-3.9 and 11.4+/-4.2 years;p=0.01.160 asymptomatic SARS-CoV-2 infections were reported, frequencies of symptoms associated with COVID-19 are shown in table 1.Five patients were hospitalized for 4-7 days. A 3½-year-old female patient succumbed during the first wave with encephalopathy and respiratory failure. The patient had been treated with MTX and steroids for systemic JIA. Genetic testing revealed a congenital immunodeficiency. No other patient needed ventilation or intensive care. One case of uncomplicated PIMS in an MTX treated JIA patient was reported.The duration of SARS-CoV-2 infection-associated symptoms was markably shorter during the 5th wave with 6.7+/-5.1 days, compared with reports from the other 4 waves (Table1).The duration of symptoms was higher in MTX treated patients (10.2+/-8.4 days) compared to patients without treatment (7.7+/-10.8;p=0.004) or patients treated with TNFi (8.2+/-4.8, p=0.002). Although patients treated with steroids also had a longer duration of symptoms (9.7+/-7.0), this was not significant.ConclusionExcept for one patient with congenital immunodeficiency who died, no case of severe COVID-19 was reported in our cohort. At the time of infection, over 60% of patients had been treated with conventional DMARDs and/or biologics. Although MTX treated patients had a slightly longer duration of symptoms, antirheumatic treatment did not appear to have a negative impact on severity or outcome of SARS-CoV-2 infection.Table 1.Characteristics and frequency of symptoms in SARS-CoV-2 infectionsN or mean (SD)1st wave N=202nd wave N=843rd wave N=384th wave N=1245th wave N=662female14532775432age at COVID-19, years12.7 (3.5)12.8 (4.3)11.8 (3.5)11.4 (3.9)11.4 (4.2)asymptomatic126132694duration of symptoms;days,11.9 (14.7)9.2 (7.0)14.1 (11.6)10.3 (7.6)6.7 (5.1)fever1218541306cough1015652245rhinitis5261344289headache4161227171sore throat61139132musculosceletal pain2751348loss of smell/taste71162113fatigue4882680dizziness122116gastrointestinal symptoms151864dyspnea1117pneumonia11bronchitis1REFERENCES:NIL.Acknowledgements:NIL.Disclosure of Inter stsAriane Klein Speakers bureau: Novartis, Toni Hospach Speakers bureau: Speaking fee Novartis and SOBI., Frank Dressler Speakers bureau: Abbvie, Novartis, Pfizer, Advisory Boards Novartis and Mylan, Daniel Windschall Grant/research support from: research funds by Novartis, Roche, Pfizer, Abbvie, Markus Hufnagel: None declared, Wolfgang Emminger: None declared, Sonja Mrusek: None declared, Peggy Ruehmer: None declared, Alexander Kühn: None declared, Philipp Bismarck: None declared, Maria Haller: None declared, Gerd Horneff Speakers bureau: Pfizer, Roche, MSD, Sobi, GSK, Sanofi, AbbVie, Chugai, Bayer, Novartis, Grant/research support from: Pfizer, Roche, MSD, AbbVie, Chugai, Novartis.

The influence of post-COVID syndrome on cognitive functions of students

A survey of senior students of the Faculty of General Medicine of the NAO MUK who had recovered from Covid-19 was conducted. The disease in all respondents proceeded in a mild form or moderate severity. Post-covid syndrome developed in students who had a coronavirus infection in the form of moderate severity. The most frequent complications were loss of smell and taste, cough and shortness of breath, as well as cognitive dysfunction in the form of impaired attention, memory and thinking. The decline in performance is associated with the above violations of the central nervous system.

Use of platelet-rich plasma for COVID-19-related olfactory loss: a randomized controlled trial.

INTRODUCTION: The current study evaluated the use of platelet-rich plasma (PRP), an autologous blood product with supraphysiologic concentrations of growth factors, in the treatment of prolonged coronavirus disease 2019 (COVID-19)-related smell loss. METHODS: This multi-institutional, randomized controlled trial recruited patients with COVID-19 who had objectively measured smell loss (University of Pennsylvania Smell Identification Test [UPSIT] ≤ 33) between 6 and 12 months. Patients were randomized to three intranasal injections of either PRP or sterile saline into their olfactory clefts. The primary outcome measure was change in Sniffin' Sticks score (threshold, discrimination, and identification [TDI]) from baseline. The secondary end point measures included responder rate (achievement of a clinically significant improvement, ≥5.5 points TDI), change in individual TDI olfaction scores, and change in subjective olfaction via a visual analog scale. RESULTS: A total of 35 patients were recruited and 26 completed the study. PRP treatment resulted in a 3.67-point (95% CI: 0.05-7.29, p = 0.047) greater improvement in olfaction compared with the placebo group at 3 months and a higher response rate (57.1% vs 8.3%, odds ratio 12.5 [95% exact bootstrap confidence interval, 2.2-116.7]). There was a greater improvement in smell discrimination following PRP treatment compared with placebo but no difference in smell identification or threshold. There was no difference in subjective scores between PRP and placebo. No adverse effects were reported. CONCLUSION: Olfactory function following COVID-19 can improve spontaneously after 6 months and can improve to a greater extent with PRP injection. These data build on the promise of PRP to be a safe potential treatment option for patients with COVID-19-related smell loss, and larger-powered studies will help further assess its efficacy.

COVID-19-Associated Chemosensory Loss Continues to Decline.

Chemosensory losses have long been considered a cardinal symptom of COVID-19 infection. Recent studies have shown changing symptom profiles with COVID-19, including decreasing incidence of olfactory losses. We accessed the National COVID Cohort Collaborative database to identify patients with and without smell and taste loss within 2 weeks of COVID-19 diagnosis. Peak prevalence time intervals for variants were determined from Covariants.org. Using rates of chemosensory loss during the peak time interval for "Untyped" variants as baseline (4/27/2020-6/18/2020), odds ratios for COVID-19-associated smell or taste disturbance fell for each of the Alpha (0.744), Delta (0.637), Omicron K (0.139), Omicron L (0.079), Omicron C (0.061), and Omicron B (0.070) peak intervals. These data suggest that during the recent Omicron waves and potentially moving forward, the presence or absence of smell and taste disturbances may no longer have predictive value in the diagnosis of COVID-19 infection.

Taste And Smell Sensation Dysfunction In Covid-19 Patients

A significant proportion of people infected with SARS-CoV-2 report a new onset of smell or taste loss. The duration of the chemosensory impairment and predictive factors of recovery are still unclear. In this study, we aim to describe the prevalence and features of loss of smell (anosmia) and loss of taste (ageusia) in Covid-19 patients. This study was done during second wave of Covid -19 to assess the smell and taste sensations dysfunction in Covid-19 infected subjects. Subjects above age of 18 years who were infected with Covid -19 virus and recovered from Covid-19 infection were included in this study. 50.49 % subjects had loss of smell sensation. 36.76% subjects had loss of taste sensation, whereas 34.31 % subjects had loss of both smell and taste sensation. Chemosensitive dysfunction is associated with coronavirus disease and may be the only symptom that presents the disease. Smell and taste loss are highly prevalent in COVID-19.

Olfactory dysfunction in patients with Wilson's Disease.

INTRODUCTION: Many neurodegenerative disorders are associated with olfactory dysfunction (OD), but little is known about OD in Wilson's Disease (WD). We evaluated olfactory function in patients with WD. MATERIAL AND METHODS: OD was examined in 68 patients with WD and 70 sex- and age-matched healthy controls using subjective testing with 'Sniffin Sticks'. Threshold discrimination identification (TDI) score and its three components (odour detection threshold, discrimination, and identification) were assessed. RESULTS: Compared to controls, patients with WD had a significantly weaker sense of smell in terms of TDI (p < 0.01), odour discrimination (p < 0.01), and identification (p < 0.01), but not in terms of odour detection threshold (p = 0.27). Patients with predominantly neurological symptoms were characterised by greater OD by TDI (p < 0.01), odour detection threshold (p = 0.01), and discrimination (p = 0.03). The presence of pathological lesions (p = 0.04) in brain magnetic resonance imaging and generalised brain atrophy (p = 0.02) predisposed to worse TDI. In the WD group, weak inverse correlations between age and TDI score (r = -0.27), odour detection threshold (r = -0.3), and discrimination (r = -0.3) were found. Male gender was a risk factor for abnormal TDI in both WD and controls (both p = 0.02). CONCLUSIONS: Patients with WD, particularly older individuals, more frequently had OD than healthy volunteers. Predominantly neurological symptoms, and the presence of typical brain MRI changes, predisposed patients with WD to smell disorders.

Persistent olfactory dysfunction associated with poor sleep quality and anxiety in patients with long COVID.

Introduction: Poor sleep quality have been widely reported in patients with long COVID. Determining the characteristics, type, severity, and relationship of long COVID with other neurological symptoms is essential for the prognosis and management of poor sleep quality. Methods: This cross-sectional study was conducted at a public university in the eastern Amazon region of Brazil between November 2020 and October 2022. The study involved 288 patients with long COVID with self-report neurological symptoms. One hundred thirty-one patients were evaluated by using standardised protocols: Pittsburgh sleep quality index (PSQI), Beck Anxiety Inventory, Chemosensory Clinical Research Center (CCRC), and Montreal Cognitive Assessment (MoCA). This study aimed to describe the sociodemographic and clinical characteristics of patients with long COVID with poor sleep quality and their relationship with other neurological symptoms (anxiety, cognitive impairment, and olfactory disorder). Results: Patients with poor sleep quality were mainly women (76.3%), 44.04 ± 12.73 years old, with >12 years of education (93.1%), and had monthly incomes of up to US $240.00 (54.2%). Anxiety and olfactory disorder were more common in patients with poor sleep quality. Discussion: Multivariate analysis shows that the prevalence of poor sleep quality was higher in patients with anxiety, and olfactory disorder is associated with poor sleep quality. In this cohort of patients with long COVID, the prevalence of poor sleep quality was highest in the group tested by PSQI and were associated with other neurological symptoms, such as anxiety and olfactory dysfunction. A previous study indicates a significant association between poor sleep quality and psychological disorders over time. Recent studies involving neuroimaging found functional and structural changes in Long COVID patients with persistent olfactory disfunction. Poor sleep quality are integral part of complex changes related to Long COVID and should be part of patient's clinical management.

Incidence of Anosmia among Covid 19 patients in India.

The pandemic COVID-19 has relentlessly caused havoc to human life since its outbreak in December 2019. The disease has been a challenge for all. The clinical manifestations of Covid-19 ranges from no symptoms at all to severe acute respiratory distress syndrome. Anosmia being one of the important clinical features of COVID-19 has always been overlooked by the Indian population. This formed the background for this study. Aim To identify the incidence of anosmia reported in COVID- 19 patients in India. Materials and Methods Literature search was carried out from January 2020 to March 2021 in databases like PUBMED and Google Scholar using the key words "ANOSMIA", "HYPOSMIA" and "OLFACTORY DYSFUNCTION" in conjunction with "COVID-19", "SARS-COV-2", and "CORONAVIRUS". Boolean operators were used to narrow and broaden the search. The search yielded sixteen eligible articles. Result The scrutiny of the 16 articles revealed an incidence range of anosmia from 9.2% to 82% and an average anosmia incidence rate of 30.19%. The cumulative incidence rate of anosmia in those studies where objective analysis was done is 52.2% and 16.4% for subjective analysis. Discussion The prevalence of anosmia in Indian population is found to be much lesser than that reported by European countries due to ethnicity or negligence. Objective evaluation of anosmia in COVID-19 patients increases the incidence of anosmia drastically. Hence objective evaluations such as UPIST, SNIFFING STICK test, etc. is to be promoted. This study also Emphasises the lack of common gold standard testing for olfaction like vision and hearing.

Loss of Smell in COVID-19 Patients: New Biomarkers.

Patients with emerging anosmia may be asymptomatic carriers of coronavirus disease 2019 infection requiring self-isolation; otherwise, there are risks of facilitating the spread of the disease.This study aims to evaluate the loss of smell with visual analogue scale and to determine the relationship between the loss of smell and blood parameters.All patients' coronavirus disease 2019 swab cultures were polymerase chain reaction positive and pneumonia was found in computed tomographies consistent with oronavirus disease 2019. The study was conducted on 114 patients hospitalized between 01.11.2020 and 31.12.2020 in the Otorhinolaryngology coronavirus disease 2019 Service of University of Health Sciences Adana City Training and Research Hospital and followed up by us.A score of 10 indicates that the olfactory function is completely normal in all patients undergoing visual analogue scale, and a score of 0 indicates that they cannot smell anything. Patients who received visual analogue scale scored 10 points were categorized as Group 1 and others as Group 2. Statistical significance level was determined as p < 0.05. A statistically significant difference was found between Group 1 and Group 2 in terms of visual analogue scale smell score, neutrophil, lymphocyte, neutrophil-lymphocyte ratio. Visual analogue scale smell score, neutrophil count, neutrophil-lymphocyte ratio value were found to be lower in Group 2 and lymphocyte count was found to be higher. Neutrophil, lymphocyte, neutrophil/lymphocyte ratio, platelet, platelet/lymphocyte ratio, which are also used in nasal diseases, may be used to detect loss of smell, predict, and even determine the prognosis of loss of smell if supported by further studies.

Can You Smell Me Now: Towards a Remote Olfactory Study

The sense of smell-olfaction involves the natural processing of ambient information in real-time. This process allows humans to detect danger, identify familiarities, and form lasting memories. During the COVID-19 pandemic, researchers were presented with challenges related to conducting in-person olfactory-based user studies. In this paper, we explore user experience and perception during olfactory-based interactions (OBI). Based upon previous literature, we propose an approach to offer future researchers a methodology for conducting olfactory-based user studies remotely. In particular, we explored a paper prototyping medium as an olfactory display. This experiment demonstrates the remote investigation of a complex sensory functionality during high mental work-load levels while participants (N=12) engage in an online memory game. Furthermore, this work seeks to inspire further discussion of olfactory-based user studies that explore functions related to human moods, memory, and behavior.

Olfactory dysfunction in COVID-19: a marker of good prognosis?

INTRODUCTION: In May 2020, the World Health Organization recognized olfactory dysfunction as a COVID-19 symptom. The presence of hyposmia/anosmia may be a marker of good prognosis in COVID-19. OBJECTIVE: To associate the presence of olfaction disorder to the clinical condition severity in patients with COVID-19. METHODS: Individuals with the flu syndrome caused by SARS-CoV-2, diagnosed from March to June 2020, were recruited. They were divided into three groups: mild flu syndrome, severe flu syndrome (admitted to hospital wards) and critical illness (admitted to the ICU). Inpatients were interviewed by telephone contact after hospital discharge and their medical records were also evaluated regarding complementary test results. Outpatients answered an electronic questionnaire containing only clinical information. RESULTS: A total of 261 patients participated in the study: 23.75% with mild flu syndrome, 57.85% with severe flu syndrome and 18.40% with critical illness. A total of 66.28% patients with COVID-19 had olfaction disorders. In approximately 56.58% of the individuals the smell alterations lasted between 9 days and 2 months. There was a significantly higher proportion of individuals with olfactory dysfunction in the group with mild flu syndrome than in the severe flu syndrome group (mild × severe - p < 0.001; Odds Ratio = 4.63; 95% CI [1.87-10.86]). This relationship was also maintained between patients with mild flu syndrome and critically-ill patients (mild × critical - p <  0.001; Odds Ratio = 9.28; 95% CI [3.52-25.53]). CONCLUSION: Olfaction dysfunction was significantly more prevalent in patients with mild flu syndrome in COVID-19. It may be a predictor of a good prognosis for this infection. New population-based studies must be carried out to corroborate these findings.

Oral lesions in patients with severe COVID-19 in the National Institute of Respiratory Diseases in Mexico: Case series

Introduction SARS-CoV-2 is a neurotropic, mucotropic, and sialotropic virus that can affect the salivary glands' function, taste sensations, smell, and oral mucosa integrity.1 The oral cavity is a perfect habitat for SARS-CoV-2 invasion due to the special affinity the virus has for cells with angiotensinconverting enzyme (ACE2) receptors, such as those from the respiratory tract, oral mucosa, tongue, and salivary glands. Aphthous lesions with necrosis and hemorrhagic crusts have been described to manifest more regularly in older adults with immunosuppression and severe COVID-19 infection;one hypothesis for the development of aphthous lesions and/or ulcers is given due to the ACE2 receptor and the SARS-CoV-2 interaction, which could alter the epithelial lining of salivary glands and keratinocytes, causing lesions in the oral cavity.4 At the same time, different etiological factors such as infections, immune system alterations, and direct trauma to the oral mucosa or epithelium,5 may be related to the stress of a prolonged hospital stay.6 Including pressure in the oral cavity conditioned by the prone position, malposition of the endotracheal tube (mainly in the corners of the lips),7 medication-related nutritional deficiencies8 such as lopinavir, and ritonavir, oseltamivir, hydroxychloroquine, among others.9-12 Thrombotic vasculopathy secondary to COVID-19 has also been described, induced by system mediators in the microvascular walls, which impairs endothelial cells, and activates coagulation factors13 and a possible hypersensitivity reaction of the mucosa to the presence of SARS-CoV-2 in the epithelium14,15;there is also the hypothesis that it could be associated with an exanthem pattern induced by the inflammatory action of the SARSCoV-2 virus,16 presented as increased levels of cytokines (including interleukin-1, tumor necrosis facto-a), and arachidonic acid metabolites (prostaglandins) secondary to the stem cell factor production and the basic fibroblast growth factor of keratinocytes from the basal layer, in relation to post-inflammatory pigmentations that could appear in areas previously affected by trauma or chronic inflammation.17 Oral manifestations in COVID-19 patients appear, on many occasions, even before respiratory symptoms, although exanthematic lesions observed in COVID-19 patients can also be observed in other viral processes. Physical examination revealed a patient in a supine position with orotracheal intubation and orogastric tube, with aphthous-type ulcers, some of them had blood crusts of different sizes on the lower lip (both skin and mucosa), dorsum, and lateral edge of the tongue, gum, and vestibular fornix (Figure 3). Initial physical examination shows the patient in a supine position supported by high-flow nasal prongs, upper and lower lips edema and ulcer-like lesions with hematic crusts on both lips (Figure 4), topical management with steroids and GELCLAIRE® Oral Gel (glycyrrhetinic acid and polyvinylpyrrolidone) is observed.

Assessment of symptoms of the post-COVID-19 syndrome in patients with different rheumatic diseases

BackgroundPatients with rheumatic diseases significantly suffer during and after infection with coronavirus disease (COVID-19). Post-COVID-19 syndrome (PCS) refers to signs and symptoms occurring during or following a COVID-19 infection that continue beyond 12 weeks. The study aimed to assess PCS symptoms in rheumatic disease patients compared to a control group not suffering from a rheumatic disease or any other chronic illness.ResultsThe prevalence of PCS symptoms was significantly higher in rheumatic disease patients compared to the control group: fatigue (69.1% vs. 41.25%), myalgia (73.5% vs. 37.5%), attention deficits (57.4% vs. 40%), and muscle weakness (33.8% vs. 13.8%). Objectively, the study group had significantly higher scores for the Fatigue Severity Scale (FSS) (35.46 ± 13.146 vs. 25.1 ± 7.587), Short-form McGill Pain Questionnaire (SF-MPQ-2) (21.66 ± 10.3 vs. 11.6 ± 3.433), and higher grades of functional disability in the Post-COVID-19 Functional Status scale (PCFS). Rheumatic disease patients had significantly higher frequencies of anxiety and depression, as assessed by the Hospital Anxiety and Depression Scale (HADS), and cognitive impairment, as assessed by the Mini-Mental State Examination (MMSE), than the controls (P = 0.023, P = 0.003, P = 0.0001, respectively). Moreover, SLE patients had the most symptoms and the highest FSS, SF-MPQ-2, PCFS, and HADS scores, as well as the lowest MMSE scores (P = 0.0001 for all except cough (P = 0.043), weakness (P = 0.015), paresthesia (P = 0.027), and anosmia (P = 0.039)). Lower disease duration, hospitalization during acute COVID-19, steroid use, smoking, and biologics non-use were significantly associated with higher PCS symptoms. Smoking was a significant risk factor (P = 0.048), and biologics use was protective (P = 0.03). Rheumatic disease patients who received two doses of the COVID-19 vaccinations had better scores on the FSS, HADS for anxiety and depression, and MMSE than those who received a single dose (P = 0.005, P = 0.001, P = 0.009, P = 0.01).ConclusionRheumatic disease patients have a higher prevalence and risk of PCS, so strict follow-up, avoiding smoking, controlling disease activity, and COVID-19 vaccinations are essential for decreasing the morbidity of PCS.

The need for sensory nutrition research in individuals with smell loss

Millions of people will now suffer from long-term smell loss as a result of infection with the SARS-CoV-2 virus. Smell is an integral component of the flavor of foods, which is one of the primary drivers of ingestive behavior. When individuals lose their sense of smell, they find food to be less flavorful and less enjoyable, which negatively impacts their quality of life. To compensate, many individuals alter their diet by focusing on tastes, chemesthesis (e.g., chili pepper heat, menthol cooling), and the texture of foods to make it more palatable. Some diet alterations, such as increasing salt use, can result in a lower diet quality, and an increased risk for chronic disease. Sensory nutrition is an area of research that focuses on how the chemical senses (e.g. taste, smell, chemesthesis) and oral somatosensation) affect dietary choices and health. Sensory nutrition strategies designed for individuals with smell loss may help improve the flavor and liking of foods while improving diet quality, and are a necessary area of future research to help improve health and quality of life in the growing population with smell loss.Copyright © 2022 The Author(s)

Advances in the study of nervous system infections in COVID‐19

Shortly after its outbreak, coronavirus disease 2019 (COVID‐19) has very rapidly spread to become a global epidemic. Early clinical findings mainly included typical symptoms such as fever and cough with a very high transmission rate. Recent findings have demonstrated neurological manifestations of atypical symptoms, which is associated with poor prognosis. In this paper, we describe the neurological aspects of COVID‐19 pneumonia in terms of relevant neurons, virus‐associated receptors, and olfactory and neurological clinical manifestations and offer insights on treatment.

Factores asociados a la anosmia y ageusia en pacientes COVID-19 de una provincia peruana

Conclusion: Anosmia and ageusia are common symptoms of COVID-19. Most patients had these symptoms associated with common symptoms. Many of those who had anosmia had nasal congestion, so it is advisable to consider differentiating them when making the diagnosis.

Persistent post-COVID-19 dysosmia: Practices survey of members of the French National Union of Otorhinolaryngology-Head and Neck Surgery Specialists. CROSS analysis.

INTRODUCTION: Persistent dysosmia more than 3 months after SARS-CoV-2 disease (COVID-19) is considered as long-COVID olfactory disease (LCOD). The primary objective of this study was to evaluate the diagnostic and therapeutic management of LCOD in the daily clinical practice of members of the National Union of Otorhinolaryngology-Head and Neck Surgery Specialists (Syndicat national des médecins spécialisés en ORL et chirurgie cervico-faciale) (SNORL). The secondary objective was to identify factors influencing management within the descriptive survey data. MATERIALS AND METHODS: A questionnaire was designed (GoogleForm®) and e-mailed to all 715 SNORL members in January 2022. RESULTS: The response rate was 7.4% (n=53/715). In total, 94.3% of respondents (n=50) had managed LCOD cases, and 56% (n=28) used psychophysical olfactory tests. Specific olfactory medical therapy involved local corticosteroid nasal sprays in 49.1% of cases (n=26) and oral corticosteroids in 32.1% (n=17). Olfactory self-training was prescribed by 81.1% of respondents, with associated speech pathologist therapy in 15.1% (n=8) of cases. No predictive factors for specific management were identified. CONCLUSION: Olfactometry is currently under-applied. Consistent with guidelines, non-drug therapy (olfactory training) is the first-line treatment for LCOD.

Intranasal Insulin for the Treatment of Persistent Post-COVID-19 Olfactory Dysfunction.

OBJECTIVE: To investigate if intranasal insulin could be a treatment option for those suffering from recalcitrant olfactory dysfunction due to COVID-19. STUDY DESIGN: Prospective interventional cohort with a single group. SETTING: Sixteen volunteers with anosmia, severe hyposmia, or moderate hyposmia for more than 60 days as sequelae of severe acute respiratory syndrome coronavirus 2 infections were selected for the study. All volunteers reported that standard therapies, such as corticosteroids, have failed to improve their olfactory function. METHODS: Olfactory function was assessed by the Chemosensory Clinical Research Center test of olfaction (COT) before and after the intervention. Changes in qualitative, quantitative, and global COT scores were investigated. The insulin therapy session consisted of placing into each olfactory cleft 2 pieces of gelatin sponge soaked with neutral protamine Hagedorn (NPH) insulin, 40 IU on each side. The procedure was repeated twice a week for 1 month. Glycaemic blood level was measured before and after each session. RESULTS: The qualitative COT score rose 1.53 points, p = .0001, 95% confidence interval (CI) (-2.12 to -0.94). The quantitative COT score increased by 2.00 points, p = .0002, 95% CI (-3.59 to -1.41). Global COT score had an improvement of 2.01 points, p = .00003, 95% CI (-2.7 to -1.3). Glycaemic blood level dropped on average 10.4 mg/dL, p < .00003, 95% CI (8.1-12.8). CONCLUSION: Our results suggest that the administration of NPH insulin into the olfactory cleft yields a rapid improvement in the sense of smell of patients suffering from persistent post-COVID-19 olfactory dysfunction. Moreover, the procedure seems to be safe and tolerable.
