ABSTRACT
Introduction. Allergic diseases in the world have increased in the last century,
requiring novel treatments to improve the quality of life of patients. As a result,
immunotherapy has emerged as a therapeutic option. The aim of this study was to
identify aspects of adherence to sublingual (SLIT) and subcutaneous (SCIT) immunotherapy
and reasons for non-adherence.
Materials and methods. We present a retrospective
study of patients with allergic diseases (rhinitis, asthma or atopic dermatitis)
who initiated SCIT or SLIT at the allergology clinic in a health institution in Medellin,
Colombia. Absolute and relative distributions, descriptive statistics and Chi square
test were used for statistical analysis.
Results. A total of 144 patients were selected
(SCIT=84.7%; SLIT=15.3%). From the total of patients, 38.9% were considered adherent;
no significant differences were found in adherence according to the route
of administration (p=0.833). The most important reason for selecting the type of immunotherapy
was medical recommendation. Of the non-adherent patients, 95.5%
(n=84) discontinued the treatment. Sociodemographic characteristics of the two immunotherapy
groups were relatively similar, with no significant differences. A significant
difference was found between the service provided by the health institution and
discontinuation of treatment, being greater for the group treated with SLIT (38.5%;
p=0.007).
Conclusion. The main cause of discontinuation of immunotherapy was the
lack of approval for funding by the Health Promoting Agencies (53.6%).
