Eczema patients with cracked skin also are more susceptible to developing certain bacterial and viral skin infections, due in large part to the lack of anti-microbial peptides (AMPs) in their outer layer of skin and their defective barrier development -- which may hinder the normal production of these important immune factors present from birth. Normally when the skin is injured, the production of AMPs increases to defend against the invasion and proliferation of microbes that cause infections. In skin affected by eczema, this defense mechanism is not activated properly, allowing greater colonization of microbes and increasing the chance of infection. When this occurs, the skin flares very quickly, becoming more irritated and itchy. Typically, antibiotics are used to treat the infection.
"Overuse and prolonged treatment with antibiotics are real concerns for dermatologists who treat patients with eczema, as they are at risk for developing antibiotic resistance," said Dr. Hanifin. "The new research realm directed at the epidermal barrier and the important immune factors carries the hope that new therapeutic approaches will lead to reduced infections in eczema patients."
