Successful treatment of generalized pustular psoriasis with guselkumab.

The purpose of the article: Generalized pustular psoriasis (GPP) is a rare auto-inflammatory disease. Patients with GPP may develop life-threatening complications, including sepsis, acute renal failure, neutrophilic cholangitis, high-output congestive heart failure, acute respiratory distress syndrome and death. The therapy of GPP is very limited and the course of the disease is unpredictable.Materials and methods: We report a 60-year-old woman presenting with widespread and confluent erythematous-desquamative plaques with numerous small pustules covering almost 70% of the body surface area. Over the past years patient had undergone different types of conservative treatment regimens including topical therapy, acitretin, cyclosporin, methotrexate and long-term treatment with systemic corticosteroids. Considering the patient's overall clinical condition, we proceed to initiate the biologic therapy with guselkumab.

Results

Guselkumab (anti-IL-23) in the standard dose of 100 mg was administered subcutaneously at weeks 0, 4 and followed by a maintenance dose every 8 weeks. The remission of GPP was observed already after 12 weeks of treatment. The maintenance treatment in the period of 18 months shows stable clinical response.

Conclusions

Our results support the evidence that guselkumab could provide an effective therapeutic approach in the treatment of GPP.
