BACKGROUND: Insights into the pathogenesis of psoriasis have provided opportunities to target key steps in the disease process. Tumor necrosis factor-alpha (TNF- alpha) being crucial to the pathogenesis of psoriasis, monoclonal antibodies against this cytokine have proved useful in its treatment. AIM: To study the efficacy of chimeric monoclonal antibody to TNF- alpha (infliximab) in Indian patients with recalcitrant psoriasis vulgaris. MATERIALS AND METHODS: Three patients with recalcitrant psoriasis vulgaris were studied. Baseline haemogram, biochemical parameters, chest radiograph and Mantoux skin test were performed. A loading dose regimen of 5 mg/kg infliximab was administered at weeks 0, 2 and 6. PASI assessment, adverse drug event monitoring and laboratory assessments were carried out at 2-week intervals until week 10. Patients were followed up until week 22 for relapse. RESULTS: Infliximab was well tolerated. The mean PASI was 25.4 at presentation and declined to 5.5 at 10 weeks. PASI 75 was attained at a mean of 9.6 weeks. Relapse occurred at a mean of 18.6 weeks after the first infusion. CONCLUSIONS: This study on Indian patients brings out the importance of cytokine-based therapies in psoriasis. Indigenous production could make these therapies a viable therapeutic option for psoriasis patients in the near future.

Autoimmune diseases are commonly encountered in dermatology practice. While the association of two autoimmune diseases in the same individual is not unknown, it is relatively rare for the second disease to be suspected based on cutaneous manifestations. We present two such cases wherein cutaneous manifestations were the first clue to the development of lupus erythematosus in a setting of autoimmune thyroiditis. Further, we have reviewed literature on this uncommon occurrence and discuss various aspects of this association.
