Unexpected drug-induced Raynaud phenomenon: Analysis from the French national pharmacovigilance database

Cyanotic Raynaud's phenomenon induced by amphotericin B deoxycholate: A case report

A 59-year-old male patient with chronic headache was admitted to the emergency department due to cryptococcal meningitis. His past medical history was marked by liver transplant 18 months prior to admission. Induction therapy with amphotericin B deoxycholate was initiated and the patient developed cyanotic Raynaud's phenomenon related to the infusion. The antifungal treatment was switched to liposomal amphotericin B, with complete resolution of the phenomenon.

Raynaud's Phenomenon after COVID-19 Vaccination: Causative Association, Temporal Connection, or Mere Bystander?

Herein, we report a case of a new-onset Raynaud's phenomenon (RP), which occurred in an otherwise healthy 31-year-old Caucasian woman, who lacked any known risk factors and associations with possible causes for secondary RP. However, 2 weeks prior to the development of RP, the patient had received her first injection of the COVID-19 vaccine containing ChAdOx1-SARS-COV-2. The patient presented with well-demarcated, white-pale, cold areas involving the middle fingers of both hands and the ring finger of the right hand, which were triggered by exposure to cold environment and accompanied by a sensation of numbness. Infrared thermography revealed notable temperature differences of up to 10.9°C between affected and nonaffected fingers. Coagulation and immunological parameters, including cryoglobulins and pathological autoantibodies, were within the normal range and antibodies to the heparin/platelet factor 4 complex not detectable. It remains unclear if the development of RP in our patient is causally related to antecedent COVID-19 vaccination; however, the temporal connection to the vaccination, the complete absence of RP in her past medical history, and the lack of any risk factors and triggers raise the suspicion of a yet unknown association with the vaccine. Whether a clear association between the development of RP and COVID-19 vaccination exists or whether RP represents a bystander effect needs to be awaited in case observational reports on RP accumulate. Given the steadily rising numbers of people receiving COVID-19 vaccinations, physicians may remain alert to still unrecognized side effects.

Secukinumab-induced Raynaud's phenomenon: first report in the literature

Secukinumab is an IL-17A antagonist that has proven efficacy in the treatment of patients with ankylosing spondylitis (AS) and psoriatic arthritis. Side effects of the drug include infections, skin rashes, and allergic reactions. Raynaud’s phenomenon (RP), a vasospastic syndrome and an important feature of different connective tissue diseases, is not an expected finding in AS patients. This article reports the development of secukinumab-related RP in a 35-year-old female patient with AS. Treatment with secukinumab was continued and RP was treated with low-dose aspirin and a calcium-channel blocker.
