Estimation of tissue and serum lipocalin-2 in psoriasis vulgaris and its relation to metabolic syndrome

Adipose tissue is now considered an endocrine organ secreting different cytokines known as adipocytokines. Lipocalin-2 has been recently identified as an adipokine present in the circulation, it is related to insulin resistance, obesity, atherosclerotic diseases and type 2 diabetes. Lipocalin-2 and...

Description
Summary:Adipose tissue is now considered an endocrine organ secreting different cytokines known as adipocytokines. Lipocalin-2 has been recently identified as an adipokine present in the circulation, it is related to insulin resistance, obesity, atherosclerotic diseases and type 2 diabetes. Lipocalin-2 and psoriasis are assumed to be closely associated with the metabolic syndrome. The aim of the present study is to estimate the level of lipocalin-2 in the serum and tissue of psoriatic patients and to correlate these levels with markers of metabolic syndrome, CRP and disease severity. This study was done on 30 patients of psoriasis and 30 healthy controls. All patients and controls were subjected to clinical examination. Serum, tissue levels of lipocalin-2 and C-reactive protein (CRP) were measured by enzyme linked immunosorbent assay technique. Metabolic syndrome parameters including anthropometric measures, lipid profiles, blood sugar and blood pressure were studied. Patients with psoriasis showed significant association with metabolic syndrome parameters than controls. Tissue lipocalin-2 was significantly higher than serum levels in psoriasis patients. A significant difference was detected in tissue levels of lipocalin-2 and not in the serum between patients and controls. Both tissue and serum lipocalin-2 correlated with CRP. Although there was a correlation between tissue and serum levels of lipocalin-2 in patients, there was no correlation between both of them with metabolic syndrome and related disorders. Our results revealed that patients with psoriasis are at increased risk of metabolic and cardiovascular complications, tissue lipocalin-2 is more specific to psoriasis than serum lipocalin-2. Lipocalin-2 has no role in determining severity of the disease. Neither tissue nor serum lipocalin-2 conveys cardiovascular risk in psoriasis patients.
