Therapeutic supplementation with zinc in the management of COVID-19-related diarrhea and ageusia/dysgeusia: mechanisms and clues for a personalized dosage regimen.

Zinc supplementation is indicated for diarrhea and taste disorders, which are both features of COVID-19 . Nevertheless, this strategy has not been tested for the treatment of these secondary complications in the current pandemic. Through an updated review, a practical appraisal was considered as a means of providing a medical nexus of therapeutic zinc regimens as an adjunct in the management of COVID-19-related diarrhea and ageusia/dysgeusia. While diarrhea and taste disorders are consequences of COVID-19, zinc supplementation is useful for non-COVID-19 patients with these clinical problems. The overwhelming evidence for supplementing with zinc in diarrhea and pneumonia is associated with the treatment of children, while for taste disorders the use of supplementing with zinc is more examined in adults. Whereas COVID-19 is more prevalent in adults, precautions should be exercised not to translate the zinc dosage used for children with diarrhea and taste disorders into the current pandemic. Therapeutic doses of zinc used for adults (∼50-150 mg/day of elemental zinc) could be included in the treatment strategies for COVID-19, but this proposal should be examined through randomized studies.

The outcome of fluticasone nasal spray on anosmia and triamcinolone oral paste in dysgeusia in COVID-19 patients.

BACKGROUND: To study the outcome of fluticasone nasal sprays in smell disorders and triamcinolone paste in taste dysfunction in a population of laboratory-confirmed SARS-CoV-2 patients as the test group. The control group will not be given any intervention and only monitoring of these symptoms will be done to compare the recovery time. METHODS: This prospective interventional study was conducted from June to Nov 2020 at, Datta Meghe University during the COVID-19 outbreak. The 120 enrolled patients were tested at days 1 and 5 after proven infection by RT-PCR test. RESULT: The mean age for all cases is 50.88 ± 15.93 years, whereas for the controls mean age is 51.2 ± 14.89. 2. Among cases 45 (75%) were males and 15 (25%) were females, among controls 43 (71.66%) were males and 17 (28.33%) were females. Among the case group, after the use of fluticasone spray in the nose and triamcinolone paste in the mouth there was a statistically significant improvement in recognizing all the odours and taste on day 5 compared to day 1. On comparing the smell and taste of cases and control group, either there is no improvement or worsening in smell or taste on day 5 in the control group. CONCLUSION: The use of fluticasone nasal spray and triamcinolone paste had immensely influenced the basic senses such as smell and taste. Our study showed that olfactory and taste function significantly improved in patients with COVID-19. For all anosmia and dysgeusia cases who received fluticasone nasal spray and triamcinolone medications the recovery of smell senses and the taste was within a week.
