ABSTRACT
BACKGROUND: Allergen-specific immunotherapy (AIT) is accepted as the only disease-modifying therapy for IgE-mediated allergic airway diseases and hymenoptera venom allergy. AIT requires repeated contact between patient and physician or nurse in the hospital. Because it is a long-term treatment, compliance is essential issue to obtain maximal efficacy. Coronavirus disease 2019 (COVID-19) pandemic reshaped doctor-patient interaction and pattern of hospital admissions. OBJECTIVE: We aimed to determine the possible changes in the administration of AIT and associated factors, in addition to the characteristics of patients diagnosed with COVID-19 infection. METHODS: Adult patients who underwent AIT for hymenoptera venom allergy, allergic rhinitis or allergic asthma between 11 March 2020 and 31 January 2021 were included in our retrospective study. Perennial and preseasonal AIT practices were evaluated. We identified patients with COVID-19 infection among the ones who received AIT. RESULTS: The mean age of 215 patients was 37.8±11.9 years and 52.1% of the patients were female. In our study, 35.4% of perennial AIT patients did not continue treatment after the COVID-19 pandemic, and the cause was patient-related in 66.7% of the cases. Compliance was 70.7% in patients receiving perennial AIT. The highest compliance rate for AIT was for venom allergy (86.5%). Thirty-four patients (15.8%) were diagnosed with COVID-19 infection. No mortality due to COVID-19 infection was observed in those who underwent AIT. CONCLUSION: COVID-19 pandemic has reduced compliance to AIT. Compliance was higher in venom immunotherapy than in aeroallergens. Severe COVID-19 infection and COVID-19 related death were not observed in patients receiving AIT.
ABSTRACT
BACKGROUND: This year, pollen season coincided with the first wave of the coronavirus disease 2019 pandemic. Strict preventive measures have been implemented during April and May and then a normalization phase started in our country in June. Our aim is to evaluate the effect of preventive measures during the pandemic process on allergic airway disease symptoms. METHODS: A prospective questionnaire-based study was planned and a questionnaire form was sent to the cell-phones of the subjects with pollen allergy followed in our clinic. Number of airborne grass pollens was determined by Burkard volumetric 7-day spore trap. RESULTS: A total of 222 pollen allergic patients were included in the study. At the beginning of the pandemic, majority of the subjects were spending time mostly indoors. The rate of home-office workers gradually decreased and the rate of office workers and the number of days at work increased from April to June, significantly. Nasal and ocular symptoms of the patients, also increased in June compared to April and May and, approximately one-third of the patients had less symptoms when compared to the same period of the previous year. The rates of using a face mask and taking a shower on return home were high among the subjects during all season. CONCLUSION: Our study showed that spending less time outside during the pollen season and wearing a mask outdoors reduces exposure to pollens and causes a reduction in symptoms. Thus, strict application of measures that cannot be applied in daily practice can make a significant contribution to the management of seasonal allergic rhinitis.
