PATCH I & PATCH II
Randomised controlled trials to investigate whether prophylactic antibiotics can prevent further episodes of cellulitis (erysipelas) of the leg
This protocol describes two closely related trials looking at the impact of 6 and 12 months of prophylaxis on subsequent episodes of cellulitis of the leg.
Details of the disease
Cellulitis of the leg is a common, painful and serious infection of the skin and the tissues just below the skin surface. It appears as a red area of skin that feels hot and tender, and it may spread rapidly. Around 2-3% of all people admitted to hospital have cellulitis and they usually have to stay in hospital for around nine days. Up to half of patients treated suffer from repeat attacks, or other difficulties such as swelling of the leg and ulceration.
The research
These two studies will tell us if low dose penicillin given after an attack of cellulitis can prevent further attacks and complications, such as swelling and ulceration.
This was a randomised controlled trial in which people with cellulitis were given either penicillin or a placebo tablet for 12 months for PATCH I or six months for PATCH II. We continued to monitor these people for two to three years, to see if the penicillin group have fewer attacks of cellulitis than the placebo group. Positive results could show that this simple treatment can make a big improvement to the quality of life of the thousands of people in the UK who suffer from repeat attacks of cellulitis. Preventing further attacks will also save money for the NHS by reducing hospital admissions.
These studies took place from October 2005 to December 2010. (Follow up continues to July 2011 for PATCH I.)
