Opinion Statement
A high proportion of suicides visit their medical provider in the month
prior to death, but depression, suicidal thoughts, and substance use are seldom
addressed. For the clinicians routinely treating a substantial patient
population with allergic diseases, there are additional concerns, as allergy has
been linked with both depression and suicidal behavior. While psychotropic
medications may affect diagnosis of allergies, medications used to treat
allergies impact mood and behavior. Thus, we present an overview of the overlap
of allergic rhinitis with depression and suicidal behavior in adults, based on
clinical and epidemiological data, and our research and clinical experience. In
summary, we suggest: 1) inquiring among patients with allergies about personal
and family history of depression, substance use disorders, suicidal ideation and
attempts 2) increased mindfulness regarding the potential effects of allergy
medications on mood and behavior; and 3) for people identified with certain
types of depression or increased suicide risk, a systematic multilevel
collaborative approach. While for practical reasons the majority of patients
with depression will continue to be treated by general or family practitioners,
the allergy-treating provider should always consider integrated care for
bipolar, psychotic or suicidal depression and incomplete remission, or relapsing
and highly recurrent course. While awaiting results of much needed basic and
clinical research to guide clinical approach for patients with comorbid allergic
rhinitis and depression, the simple steps recommended here are expected to
improved clinical outcomes in depression, including, on a large scale, reduced
premature deaths by suicide.
