Abstract
Raynaud's phenomenon (RP) is a medical condition characterized by vasospasm of the digital vessels in the fingers and toes. The prevalence of RP in the general population is estimated at 3-5% and can vary based on climate. It is classified into primary and secondary RP based on causality. RP has been reported in some cases diagnosed with coronavirus disease 2019 (COVID-19) infection. We report the case of a 14-year-old Caucasian female who presented during the pandemic with chief complaints of suicidal ideations and attempted suicide and had a history of attention-deficit hyperactivity disorder (ADHD) and persistent RP after a stimulant trial. After an initial failure of treatment with lisdexamfetamine, she was switched to methylphenidate hydrochloride (MPH). Within two months of starting MPH, the patient noticed skin discoloration of the lower legs and feet along with numbness. The discoloration of skin was mainly limited to her feet and gradually moved up her legs. She was advised to discontinue the MPH, but her symptoms persisted for four more months until her admission. Other etiologies were ruled out by multi-specialties and during her hospitalization. She was started on atomoxetine and buspirone with appropriate dose titration. Post-discharge from the hospital, no improvement was observed in the patient's RP at an outpatient follow-up performed within a month. The development of RP following MPH treatment and its persistence after stopping MPH is a fascinating event. Clinicians should be aware of the potential rare side effects of stimulants and stimulant-like medications, including vascular, hematological, and dermatological effects. Adolescents with ADHD may be particularly distressed by the COVID-19 pandemic and display increased behavioral issues. Stress can be a trigger for RP; therefore, minimizing stress in at-risk patients is essential.
