Orbital Cellulitis in a Psoriatic Patient Treated With Adalimumab.

Introduction: Psoriatic patients on tumor necrosis factor alpha inhibitors (TNFi) may be at increased risk for upper respiratory tract infections, including chronic rhino-sinusitis (CRS). Rarely, CRS can progress to orbital cellulitis (OC), an emergent ophthalmic complication wherein respiratory flora from paranasal sinus disease intrude the retro-orbital space. Materials and Methods: Single case report. Results: We report the first case, to our knowledge, of an invasive sinusitis that rapidly evolved into OC in a patient receiving adalimumab treatment for plaque psoriasis and psoriatic arthritis. After TNFi withdrawal and appropriate medical and surgical intervention, the patient fully recovered. However, on resumption of TNFi therapy, symptoms of recalcitrant CRS returned. Conclusion: More investigation is needed to explore how TNFi might predispose to chronic, refractory rhino-sinusitis and subsequent progression to OC. Military physicians and other medical providers should be aware of this proposed new disease entity and the potential for rapidly evolving and invasive infections in immunocompromised patients. Screening and monitoring for chronic infectious disease, such as CRS before initiating and during TNFi therapy is warranted.
