Pustular Psoriasis: Recognizing and Treating A Rare But Serious Disease

Pustular psoriasis is a clinically heterogenous group of rare psoriasis subtypes characterized by aseptic, neutrophil-rich pustules. The three most common types are generalized pustular psoriasis, palmoplantar pustular psoriasis, and acrodermatitis continua of Hallopeau. The diagnosis of pustular psoriasis relies mainly on clinical features and is challenging. Recent guidelines on diagnosis, classification, and assessment of severity have been published by ERASPEN and by the Japanese Dermatological Association.  

Current systemic treatment has involved cyclosporine, methotrexate or acitretin. The Japanese Dermatological Association has also published guidelines that include a treatment algorithm. However, it has been recognized that IL-36 cytokines are likely the key driver of the autoimmune response in pustular psoriasis. There are two novel, investigational monoclonal antibodies that target the IL-36 receptor. In addition, agents that target other molecules have also been investigated.

Pustular Psoriasis: Recognizing and Treating A Rare But Serious Disease will review the most recent guidelines for diagnosing, classifying, and assessing the severity of pustular psoriasis and provide information on current treatment guidelines and agents in development to manage this rare group of disorders.

Welcome and Introductions
Diagnosing and Assessing Severity of Pustular Psoriasis
Managing Pustular Psoriasis
Q & A Session and Activity Roundup

Target Audience

The intended audience for this educational initiative is dermatologists, the clinicians who manage patients with pustular psoriasis.

Learning Objectives

At the conclusion of this activity, participants should be able to:

  • Discuss how the pathophysiology of pustular psoriasis differs from that of plaque psoriasis
  • Employ the most recent consensus recommendations to diagnose and classify pustular psoriasis
  • Apply the most recent guidelines when managing patients with pustular psoriasis
  • Assess the mechanism of action, efficacy, and safety of agents in development for managing pustular psoriasis

Alice B. Gottlieb, MD, PhD is an internationally recognized expert in the field of psoriasis and psoriatic arthritis. Her research uses targeted immunobiologics as pathogenic probes, providing new understanding of the pathogenesis of psoriasis and providing the foundation for biologic drug development in these two debilitating diseases. Through a study she had published in Lancet in 2001, Dr. Gottlieb was the first to show the efficacy of TNF blockers as monotherapy for moderate to severe psoriasis. Her research led to multiple TNF blockers being FDA-approved for psoriasis which revolutionized the care of psoriasis and psoriatic arthritis patients. In addition, Dr. Gottlieb was one of the first scientists to demonstrate that psoriasis is a T cell mediated disease. She showed that treatment with a T cell-specific immunotoxin cleared psoriasis clinically and histologically. With her published studies and public presentations she has been able to convince pharmaceutical companies to use psoriasis as their proof-of-concept disease when testing new immunomodulators that may decrease T cell and dendritic cell cytokine production. So far, her research has affected drug development in psoriasis, psoriatic arthritis, rheumatoid arthritis, inflammatory bowel disease and transplantation.

This activity has been planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of the Potomac Center for Medical Education and Rockpointe. The Potomac Center for Medical Education is accredited by the ACCME to provide continuing medical education for physicians.

The Potomac Center for Medical Education designates this enduring material for a maximum of 1.0 AMA PRA Category 1 Credit. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

For questions regarding CME/MOC credit or the evaluation, please email [email protected].

Successful completion of this CME activity, which includes participation in the evaluation component, enables the participant to earn up to 1.0 Medical Knowledge MOC points in the American Board of Internal Medicine's (ABIM) Maintenance of Certification (MOC) program. It is the CME activity provider’s responsibility to submit participant completion information to ACCME for the purpose of granting ABIM MOC credit.
To receive CME credit and/or MOC points, you MUST pass the post-test and complete the evaluation. For ABIM MOC points, your information will be shared with the ABIM through PCME's ACCME Program and Activity Reporting System (PARS).
