Novel applications of Cold Atmospheric Plasma for the treatment of Plaque Psoriasis

Abstract

Plasma is the fourth state of matter other than solid, liquid and gases. About 99 percent of mixture of free positive negative charges, neutral particles and photons. The plasma exists in two forms: hot plasma and cold plasma. Hot plasma is used in metallurgical operations while cold plasma is used in medical, skin psoriasis treatment, food agricultural, preservation and waste water treatment. Many clinical studies prove the effectiveness of cold plasma in dermatological disease management. Recent researches have established that combined use of cold plasma and nano-formulations is helpful in delivery of poorly water-soluble drugs. Plaque psoriasis is an autoimmune disorder in which silvery, thick, dead layer of skin shades off and cause inflammation, sometimes bleeding. It occurs in 3-4 percent of total world population. Scientific studies have proved that nano-scale particles permeate easily and interact with immune cells like lnterleukin-16, cytokines and TNF-alfa during inflammation and autoimmune disorders. As a result of which, thick layer of keratinocytes is produced and formation of TNF-alfa and interleukin is inhibited which are the causes of Plaque psoriasis. Since conventional medication has only been helpful in managing it, researches have been carried out using various techniques like phototherapy, use of UVA, UVB, IPL (Intense Pulsed Light), PDL (Pulsed Dye Light), LASER and low-level LASER light etc. but their excess exposure causes risk of skin cancer. Other therapies like use of nanometric Liposomes, Niosomes and their combination therapy are some novel clinical techniques for combating symptoms but are still in clinical trial. Since, Plasma therapy is non irritating and stops the triggering mechanism of inflammation, hence the use of nanotechnological topical formulation in combination with plasma therapy has the potential to become possible treatment of Plaque Psoriasis in future.
