CLINICOEPIDEMIOLOGICAL STUDY OF CHILDHOOD PSORIASIS PATIENTS AND ITS ASSOCIATION WITH HLA-CW6 IN A TERTIARY CARE CENTRE OF EASTERN INDIA

Abstract

BACKGROUND- Psoriasis is chronic common papulosquamous disorder. Its aetiology included various environmental and genetic factors. In genetics, HLA-Cw6 is most commonly associated with psoriasis. Childhood psoriasis is also common in worldwide population. However, very few studies done on epidemiological data and HLA-Cw6 analysis in childhood psoriasis patients. AIMS AND OBJECTIVE- Clinicoepidemiological study of childhood psoriasis patients and its association with HLA-Cw6 in a tertiary care centre of Eastern India MATERIALAND METHOD- We conducted a cross-sectional study in a tertiary care centre and recruited 20 patients of psoriasis with age group below 18 years after taking proper consent. Clinical history and blood was taken from them and HLA-Cw6 analysis was done by PCR method. Data compilation was done by Microsoft excel using SPSS software. RESULTS- A total of the 20 childhood psoriasis patients, 9 were males and 11 were females. Generalized plaque type psoriasis (N=19) is commonest followed by guttate psoriasis (N=1). None of the patients had arthalgia. Family history was present in only 3 patients. Higher numbers of childhood psoriasis patients (N=14) were positive for HLA-Cw6. Also Higher numbers of females (N=10) were positive for HLA-Cw6. ve patients had nail changes. CONCLUSION- We found HLA-Cw6 is strongly associated with childhood psoriasis and also HLA-Cw6 frequency is higher in female than male childhood psoriasis patients.
