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.

It is a study of sociogenic need satisfactions that determines the homeostasis of 'being' by remaining contingent conditions of perpetuation or debasement of the social 'self'. The paper has a focus on identification satisfaction and differentiation experience of patients of the highly stigmatized leprosy. The study proceeds with an 'Experimental Group--Control-Group' randomized design. Experimental Groups are two, viz., those of Lepromatous and Non-lepromatous patients. 'Control Group' consists of 'disease-free' normal people. The three independent variables are disease types, age, personality factors. The dependent variables are two, viz., score of identification satisfaction and differentiation experience, measured by standardized tools. Each dependent variable has four '3 X 3 X 2' factorial experiments to test 56 'Null Hypotheses'. The sample consists of 360 elements for each one of the eight experiments. Leprosy elements are drawn from the Central JALMA Institute for Leprosy and the 'Kushta Seva Sadan' (Agra). The 'F' test is run for statistical verification of 'Null hypotheses'. Results show presence of 'role-reversion' and 'role negation' of age and personality factors. The disease possesses 'anti-roles'. It does not allow age and personality factors to promote identification satisfaction and to demote differentiation and experience. The disease actively promotes differentiation and demotes identification through its own 'alien system'. The senescents are the greatest sufferers. 'Social Stigma' works a 'social thanatos' and exposes senescents to substantial 'self-erosion'.
