Objective: To quanitate the serum sodium and potassium in patients with psoriasis and to identify the probable cause of hyperkalemia in psoriasis. Introduction: The pathologic process is likely due to dysregulation of activated T-cell interactions with antigen presenting cells and overproduction of inflammatory cytokines such as interferon-α and tumor necrosis factor-alpha. Methodology: 24 psoriatic patients on first presentation at dermatology OPD were included in this small pilot study. The blood samples were analysed for the serum electrolytes namely sodium and potassium were analysed by the Ion selective electrode method adopted in the automated computerised electrolyte analyser. Any other disorders which also lead to hyperkalemia were not considered Results and Discussion: The obtained data was analysed by student ‘t’ test. Sodium (P< 0.001) and Potassium (P< 0.001) were statistically significant. This present study shows that, there was significant elevation of potassium ion in patients with psoriasis. This suggests that it might due to the Na/K ATPase pump activity. Conclusion: Alteration in the activity of Na+ and K+ pump or Na-K-co transport might be the cause which needs further study.
