2 A Randomized Controlled Trial Evaluating the Efficacy of Local Budesonide Therapy in the Management of Hyposmia in COVID-19 Patients Without Signs of Severity

The initial symptoms described in the first cases of COVID-19 were mainly fever and respiratory signs. Recently, there has been an increase in cases of hyposmia without associated nasal obstruction or rhinorrhea. Although we do not yet know the long-term consequences of COVID-19 on olfaction, there is evidence in the literature demonstrating that post-viral hyposmias are an important source of long-term olfactory disorders, impacting quality of life. Usually, the treatment of viral hyposmias is based on local and/or general corticosteroid treatment combined with saline nasal irrigation at the onset of signs. Because of the possible development of severe forms of the SARS-Cov-2 infection, the French Society of Otorhinolaryngology has advised against treatment by corticosteroid therapy and nasal irrigation. However, as the virus is present in the nasal fossae on average for 20 days, persistent hyposmia at 30 days would probably result from an inflammatory or neurological damage to the nasal slits or olfactory bulb. Local treatment with corticosteroids could then be instituted from 30 days after the onset of symptoms of COVID-19 without risk of dissemination. In persistent hyposmia other than chronic rhinosinusitis, the only treatment that has proven its efficacy is nasal irrigation associated with budesonide and olfactory rehabilitation. However, this drug does not have marketing authorisation in France for this indication.

3 Olfactory Retraining Therapy and Budesonide Nasal Rinse for Anosmia Treatment in Patients Post-CoVID 19. A Randomized Controlled Trial

The study will be a randomized controlled trial, involving patients with hyposmia/anosmia of onset immediately after an upper respiratory viral illness, assigned to three distinct study arms. Nasal irrigations will be prescribed to all three groups (BID). In addition, one arm will receive a paper hand-out about post-viral anosmia with instructions to smell common household items (current care) and act as a control group. The second group will receive an essential oil retraining kit, whereas the third group will receive the same olfactory training kit and a prescription to use budesonide with the nasal irrigations. Olfactory scores will be tested at the enrollment, 3 months and at 6 months.

6 Investigating Anosmia and Ageusia in COVID-19 Adult Patients in Saudi Arabia

COVID-19 has adversely affected the healthcare system across the world. The world was not prepared for global outbreak of infectious diseases. The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is enabling researchers worldwide to acquire a large amount of clinical data regarding coronavirus disease (COVID-19). The COVID-19 infection severely affects the respiratory system in the critical cases and results in mortalities. The affected people experience a dry cough, fever, breathing problems, diarrhea, muscle pain, and sore throat. Besides that, some of the evidence from Italy, South Korea, China, and Spain suggest that the COVID-19 cases also lose their senses of smell and taste resulting in alterations in those patients. The objective of this proposed study is to determine whether COVID-19 cases have Olfactory and gustatory dysfunctions as a hallmark indicator and can be used as diagnostic tools for the isolation of suspected people. Investigators are presenting a prospective proportional case-control study that is conducted to investigate the COVID-19 cases with anosmia and /or Ageusia in a university hospital in Riyadh, Saudi Arabia. The sample size of this case series would be 250 cases of suspected COVID-19 patients. The cases included in the study are analyzed prospectively to determine if the cases had a history of anosmia and /or Ageusia, and then tested for the alteration of these senses through a panel of standardized odors/taste strips. That is looked at statistically allowing us to confirm the proposed effectiveness of these tests as a diagnostic tool.

8 Intranasal Injection of Platelet-rich Plasma Versus Saline for Treatment of Olfactory Dysfunction

This randomized clinical trial will evaluate the benefit of platelet-rich plasma (PrP) in the treatment of olfactory dysfunction. PrP can be isolated from a patient's own blood and has been found in previous studies to have anti-inflammatory and pro-regenerative properties. It has been used across multiple specialties, such as Orthopedics, Facial Plastics, Dermatology, Neurology in injected form to treat a wide variety of tissues to encourage the body's inherent regenerative capacity. We have completed a pilot study here evaluating it's use in olfactory loss which demonstrated safety and also suggested efficacy. Therefore, we aim to assess the ability of PrP to improve olfactory function in patients with decreased sense of smell.

10 Coronavirus Smell Therapy for Anosmia Recovery

As the COVID-19 pandemic spread around the world, anosmia and dysgeusia were quickly recognized as two of the key presenting symptoms. The probability of return of smell is related to severity of smell loss at presentation, but it appears that the loss of sense of smell and taste seems to persist in approximately 10% of the affected patients after 6 months. As a result of COVID-19, it is estimated that within the next 12 months > 150,000 Americans will suffer permanent loss of smell. The magnitude of this impairment on the health, safety, and quality of life is truly unprecedented and makes post-COVID olfactory disorder a major public health problem. Thus, there is a pressing need to identify effective treatments. The research questions are to determine the effects of steroid nasal saline lavage and olfactory training among adults with post-COVID olfactory dysfunction and identify confounders and modifiers of any observed effects. To answer the research question, the investigators propose a 2 x 2 factorial design blinded randomized clinical trial whereby 220 subjects with documented COVID-19 with anosmia/hyposmia of 12 weeks duration or longer from Missouri, Illinois, and Indiana will be recruited electronically from COVID patient advocacy sites, social media sites, and other internet sources. Enrolled subjects will be randomized to nasal saline lavage with topical budesonide or placebo to address the presumed role of inflammation in the olfactory cleft and each subject will also be randomized to olfactory training with patient-specific, high- or low-concentration essential oil scent to assess the role of olfactory training. Data will be analyzed in a blinded fashion to allow estimation of observed effect size for both anti-inflammatory and olfactory training. This innovative study will exploit the unique opportunities presented by COVID-19. The study will use a high-tech virtual "contactless" research strategy, including eConsent and digital mHealth techniques to obtain rapid answers to the research questions. The interventions are low-cost, readily available, and results of this study can be directly disseminated to the care of COVID-19 patients with anosmia.

Primary Outcomes

Description: The University of Pennsylvania Smell Identification Test (UPSIT) (Sensonics, New Jersey)7 is the most widely accepted olfactory identification test in North America. The UPSIT consists of four 10-page booklets, with a total of 40 items. Subjects are asked to scratch each strip with a pencil to release the scents, detect the smell, and identify the smell from the four choice options. The UPSIT comes from a scoring rubric that identifies the normalcy benchmark based on age and gender. Normosmia is defined as ≥34 for males and ≥35 for females, and an increase of 4 points or more from baseline indicates a clinically meaningful improvement. UPSIT has high internal reliability across a wide range of populations.

Measure: University of Pennsylvania Smell Identification Test (UPSIT)

Time: The within subject change in UPSIT between baseline and 12- and 24-week assessment time frame.

Secondary Outcomes

Description: The Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS) was adapted from the original 52-item Questionnaire of Olfactory Disorders. This short-modified version is a validated 17-item questionnaire about quality of life and impairments related to olfactory dysfunction. The maximum score is 51, and higher values indicate worse quality of life or higher degree of impairment of normal daily activity. Mean scores in anosmics is 19; hyposmics is 8; and normosmics is 0. Prior studies used a cutoff score of 12.5 to reflect normal vs. abnormal scores.The minimum clinically important difference is 5.2.

Measure: Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS).

Time: The within subject change in QOD-NS between baseline and assessment time frame.

Description: The Global Rating of Smell is a single-item, global rating that asks: "Overall, please rate your current sense of smell? Excellent, Very Good, Good, Fair, Poor, Absent."
