Cieľ: Cieľom práce je zistiť u koľkých pacientov s pretrvávajúcou poruchou čuchu, prípadne súčasne aj chuti, ktoré sú podmienené infekciou covid-19, sa dá subjektívne vnímanie čuchu a chuti zlepšiť metódou čuchového tréningu. Metodika: Pacienti, ktorí prekonali infekciu covid-19 (prvá a druhá vlna pandémie v rokoch 2020 a 2021) s poruchu čuchu (hyposmia, anosmia, parosmia, fantosmia) s alebo bez poruchy chuti, a pričom porucha čuchu sa neupravila do jedného mesiaca od vyliečenia, sa prihlásili na webovej stránke www.cuch.sk a požiadali o zaslanie testovacieho setu parfémovaných fixov. Po obdržaní setu sa vyšetrili v domácom prostredí, vyplnili on-line dotazník a zaslali elektronicky na Neurobiologický ústav BMC SAV. U pacientov s potvrdenou hyposmiou a anosmiou nasledovalo ORL vyšetrenie na zmluvných ORL pracoviskách v SR. 117 zaradených pacientov absolvovalo čuchový tréning, 2× denne podľa návodu. Kontrolné vyšetrenie čuchu sa robilo po 3 a 6 mesiacoch tréningu. Stav čuchu a chuti sme hodnotili vstupne aj výstupne podľa vizuálnej analógovej škály (VAS) od 1 do 10. Vstupný stav čuchu dosiahol v priemere 4 podľa VAS, vstupný stav chuti v priemere 2 podľa VAS. Parosmiu malo pri vstupe 28 pacientov, fantosmiu 18, dysgeuziu 20. Výsledky: Zlepšenie čuchu na VAS po čuchovom tréningu sme zaznamenali u 96 pacientov, čo je 73 % zo súboru 117 pacientov s hyposmiou a anosmiou. Výstupný stav čuchu dosiahol po 6 mesiadoch čuchového tréningu úroveň 8 podľa VAS. Zlepšenie chuti sme zaznamenali u 47 čo je 65 % zo súboru 72 pacientov s hypogeuziou a dysgeuziou. Výstupný stav chuti dosiahol po 6 mesiacoch čuchového tréningu úroveň 4 podľa VAS. Pretrvávanie rôznej formy dysgeuzie, parosmie či fantosmie po liečbe bolo u 18 pacientov. Záver: Čuchový (olfaktórny) tréning je v súčasnosti najdôležitejšia rehabilitačná pomôcka pre zlepšenie narušenej čuchovej funkcie po prekonanej infekcii covid-19. Lepšie subjektívne výsledky po 6-mesačnom čuchovom tréningu sa pozorovali pri reštitúcii kvantitatívnej poruchy čuchu, než pri reštitúcii kvantitatívnej poruchy chuti.
Objective: The aim of this study is to find out how many patients with an ongoing smell and taste disorder after COVID-19 infection, can improve the subjective perception of smell by olfactory training method. Methods: Patients after COVID-19 (first and second wave of the pandemic in 2020 and 2021) with persisting smell disorder (hyposmia, anosmia, parosmia, fantosmia) with or without taste disorder and while the olfactory disorder did not improve within one month afterrecovery, signed up on the website www.cuch.sk and asked for a testing set (perfumed felt-tip pens) to be sent. After a self-examination at home, each respondent filled out an on-line questionnaire and sent it to the Neurobiological Institute of the BMC SAV. Patient with confirmed hypo and anosmia underwent an ENT examination at contracted ENT workplaces in Slovakia. All the 117 patients included got through the olfactory training, twice a day, following the instructions. The control examination was performed after three and six months of smell training. Smell and taste status was evaluated by visual analogue scale (VAS) from 1 to 10 in admission and discharge of the study. According to VAS, the average entering olfactory status was 4 and the average taste status reached an average of 2. At admission, 28 patients entering the study suff ered from parosmia, 18 from phantosmia, and 20 from dysgeusia. Results: After the olfactory training, improvement of smell capability was observed in 96 patients, which is 73% from the whole group of patiets (117) with hyposmia and anosmia. The discharge olfactory score after 6 months of olfactory training reached grade 8 according to VAS. Improvement of taste capability was observed in 47 patients, which is 65% from the whole group of patients (72) with hypogeusia and dysgeusia. The discharge taste score after six months of olfacory training reached grade 4 according to VAS. However, various forms of dysgeusia, parosmia, or phantosmia persisted after the olfactory training in 18 patients. Conclusion: Smell (olfactory) training is currently considered the most eff ective rehabilitation method for improving impaired olfactory function after COVID-19 infection. Better subjective results were observed in the restitution of quantitative smell disorder than in quantitative taste disorder.

BACKGROUND: In the present study we aimed: 1) To establish the prevalence and clinical impact of DFNB49 mutations in deaf Roma from 2 Central European countries (Slovakia and Hungary), and 2) to analyze a possible common origin of the c.1331+2T>C mutation among Roma and Pakistani mutation carriers identified in the present and previous studies. METHODS: We sequenced 6 exons of the MARVELD2 gene in a group of 143 unrelated hearing impaired Slovak Roma patients. Simultaneously, we used RFLP to detect the c.1331+2T>C mutation in 85 Hungarian deaf Roma patients, control groups of 702 normal hearing Romanies from both countries and 375 hearing impaired Slovak Caucasians. We analyzed the haplotype using 21 SNPs spanning a 5.34Mb around the mutation c.1331+2T>C. RESULTS: One pathogenic mutation (c.1331+2T>C) was identified in 12 homozygous hearing impaired Roma patients. Allele frequency of this mutation was higher in Hungarian (10%) than in Slovak (3.85%) Roma patients. The identified common haplotype in Roma patients was defined by 18 SNP markers (3.89 Mb). Fourteen common SNPs were also shared among Pakistani and Roma homozygotes. Biallelic mutation carriers suffered from prelingual bilateral moderate to profound sensorineural hearing loss. CONCLUSIONS: We demonstrate different frequencies of the c.1331+2T>C mutation in hearing impaired Romanies from 3 Central European countries. In addition, our results provide support for the hypothesis of a possible common ancestor of the Slovak, Hungarian and Czech Roma as well as Pakistani deaf patients. Testing for the c.1331+2T>C mutation may be recommended in GJB2 negative Roma cases with early-onset sensorineural hearing loss.
