Impact of Comorbidities on Local Anesthetic Hypersensitivity: A Decade of Clinical Experience
Methods: Clinical data and test results of patients who were referred to our allergy clinic for evaluation of suspected LA-HR were retrospectively reviewed. Skin tests (ST) and subcutaneous provocation tests (SPT) were performed.
Results: A total of 200 patients were included in the study. The most common reason for referral was a suspected LA-HR (80%), followed by a history of HR to other drugs with a need for LA use during upcoming procedures (20%). Among 160 patients with suspected LA- HR, only 5.6% demonstrated confirmed hypersensitivity by positive ST and SPT. Of the 40 patients with a history of HR to other drugs, only 2.5% tested positive for LA-HR. A history of comorbidity was present in 70% patients. Patients with suspected LA-HR had a significantly higher prevalence of comorbidities compared to those with HR to other drugs. However, none of the patients who tested positive had a history of comorbidity.
Conclusions: Confirmed hypersensitivity risk among patients reporting LA-HR is very low. Although comorbidities were more common among patients reporting LA-HR, none of the patients with confirmed allergy had any comorbidities, underscoring the low confirmed hypersensitivity rate in this population.
