What's New in MRSA colonization

What's new in MRSA Colonization

I have been seeing an increasing number of infections, including MRSA bacteria, in my patients. This has been especially true among my teenage and college patients who play sports. Recently, a solid study corroborated what I see and showed that 8-13% of athletes are colonized with MRSA. The colonization is especially in the nostrils, but also groin (inguinal) and armpits (axillary) areas. The sports with the highest risk were wrestling (22%), football (8%), and basketball (8%). I also see high rates among patients who use mats (martial arts, gymnastics, yoga) and frequent public gym usage. The reason this is a concern is that MRSA colonization increases the risk of MRSA infection elsewhere on the body by at least 7-fold. This includes boils (furuncles), superficial skin infections (impetigo), and deep skin infections (cellulitis).

Practically speaking, if a patient has repeated infections, I oftentimes recommend treating the colonization as well. Nasal colonization is usually treated with a prescription antibiotic ointment. Studies sometimes use oral antibiotics to increase efficacy for the nose while treating the rest of the body. When possible, I prefer to avoid oral antibiotics especially when there is not an active MRSA infection and sometimes recommend whatís called a bleach bath that I explain during the appointment (please do NOT pour undiluted bleach onto the skin!). When patients perform the decolonization, I usually never see them with an active skin infection again.

If you have a skin infection or any other skin question, please make an appointment for dermatology consultation at (626) 331-6411 to discuss your options.
