Bee Venom Phonophoresis on Mild to Moderate Localized Plaque Psoriasis on Knee Joint

MTI University100 enrolled

Overview

Chronic plaque psoriasis, or psoriasis vulgaris, is a chronic inflammatory skin disease characterized by well demarcated, erythematous, scaly plaques on the extensor surfaces of the body and scalp. The lesions may occasionally itch or sting, and may bleed when injured. Dystrophic nail changes or nail pitting are found in more than one third of people with chronic plaque psoriasis, and psoriatic arthropathy occurs in 1% to more than 10%. The condition waxes and wanes, with wide variations in course and severity among individuals.

Apitherapy is an alternate therapy that relies on the usage of honeybee products, most importantly bee venom for the treatment of many human diseases. The venom can be introduced into the human body by manual injection or by direct bee stings. Bee venom contains several active molecules such as peptides and enzymes that have advantageous potential in treating inflammation and central nervous system diseases, such as Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis. Moreover, bee venom has shown promising benefits against different types of cancer as well as anti-viral activity, even against the challenging human immunodeficiency virus (HIV). Many studies described biological activities of bee venom components and launched preclinical trials to improve the potential use of apitoxin and its constituents as the next generation of drugs. Chronic plaque psoriasis is the most common form of psoriasis, accounting for more than 80% of cases. It is a chronic relapsing and remitting condition that presents as symmetrical, well-demarcated, erythematous thickened plaques with overlying silver scales. Appearance can vary depending on skin colour, ranging from pink on lighter skin to brown, purple, or grey on darker skin. It commonly affects the extensor surfaces (elbows and knees), scalp, trunk, and gluteal fold, but may arise on any part of the body. Plaques may coalesce to involve extensive areas of the skin, especially on the trunk and limbs.

Bee venom phonophoresisCOMBINATION_PRODUCT

Bee venom gel preparation with low freq ultrasound Bee venom solution (100 mg/mL) that was prepared and preserved at the correct temperature was purchased from the Egyptian Organization for Biological Products \& Vaccines (Vacsera). The solution was a mix of a crude form of BV dissolved in sterile normal saline with a concentration ratio of 1:1 vol/vol. Then, the BV gel was prepared at the laboratories of the Faculty of Pharmacy, Modern University, Cairo, Egypt, by dissolving the previous mixture in 10% propylene glycol, followed by the addition of 0.01% butylparaben. To make bee venom gel, the resulting mixture was mixed with the matrix. The BV gel had a homogeneous and translucent appearance and a pH of 7.53. There was no discoloration, phase separation, or off-putting odor. Stratification was not observed after 30 min of centrifugation at 2,500 rpm at 25◦C, used with low frequency ultrasound Device: low intensity ultrasound
