Hidradenitis suppurativa and suicide risk: a multivariate analysis in a disease with a high psychological burden

Hidradenitis suppurativa (HS) is a disorder that can lead to serious sequelae and important comorbidities. It has been associated with different mental health conditions, such as depression, anxiety or completed suicide. The objective is to analyze the suicide risk (SR) among patients in a monographic HS consultation, as well as to establish individual association factors.

Patients older than 18 years seen in our specific HS unit were consecutively included and invited to respond to the self-administered Beck hopelessness scale. Those patients with significant intellectual disabilities or severe mental health conditions, including a history of psychosis, were excluded. In addition, data related to the skin process were collected. Subsequently, it was studied whether there were significant differences between patients with absent-mild SR and those with moderate-severe SR and a logistic regression analysis was performed to determine the relationship of these variables with SR.

A total of 136 patients were included in the study, 51.5% men. Of them, 21.3% presented a moderate or severe SR (score ≥ 9 in the Beck test). This risk was significantly related to having a previous or concomitant psychiatric disorder (OR = 2.586, 95% CI 1.044-6.409, p = 0.040) followed by the history of biological treatment (OR = 2.867, 95% CI 1.004-8.182, p = 0.049). The existence of other affected relatives was confirmed as a protective factor (OR = 0.377, 95% CI 0.150-0.951, p = 0.039).

The prevalence of SR in patients with HS is higher than that of the general Spanish population. The presence of a psychiatric disorder and the need for biological treatment are established as factors that increase SR, both of which can be interpreted as a more advanced disease. As a protective factor, the presence of other cases in the family is established, which suggests a greater normalization of the disease.
