Serum apelin12 in Acne Vulgaris

Acne lesions may vary in number during the natural course of the disease and multiple measurements have been developed which is based on clinical examination and photographic documentation, to measure the clinical severity.

The Grading of acne based on the type of lesions, affected surface area and their severity that can help in deciding which therapies are needed in each individual. However, no grading system has been accepted universally. The Global Acne Grading System is a quantitative scoring system to assess the severity of acne. According to this score acne was graded as mild, moderate, severe and very severe.

The severity of acne was also graded using the Comprehensive Acne Severity Scale.

Adipokines are proteins that are synthesized and secreted primarily by adipocytes in response to various stimuli, include interleukin 6 and other small molecular weight bioactive proteins such as adiponectin, resistin, leptin, serpin E1 [also known as plasminogen activator inhibitor 1 and endothelial plasminogen activator inhibitor], visfatin (also known as nicotinamide phosphoribosyltransferase), apelin, chemerin, retinol binding protein 4, and monocyte chemoattractant protein 1.

Due to their different biological properties and diverse cellular targets adipokines are involved in a wide array of (patho)physiological processes and are responsible for mediating the inflammatory effects of the adipose tissue in the local tissue environment as well as to different organs via circulation. By detecting alterations in their serum levels also in dermatological diseases such as acne vulgaris and psoriasis, extensive studies have also started in dermatological research to identify the possible targets and the cutaneous sources of these proteins.
