What You Need to Know Before You Apply

What is the purpose of this trial?

This trial investigates how quickly a bacteria known for causing acne grows in patients who have had hip replacement surgery. The goal is to see if this bacteria might be causing infections after the surgery.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are currently using antibiotics or have used them in the past week.

Is benzoyl peroxide gel safe for use in humans?

Benzoyl peroxide gel is generally safe for use in humans, but it can cause skin irritation and allergic reactions in some people. In studies, most adverse events were mild or moderate, and serious reactions were rare, with a reporting rate of under 1% over 20 years of use.12345

How does benzoyl peroxide gel differ from other treatments for total hip arthroplasty?

Benzoyl peroxide gel is unique in the context of total hip arthroplasty because it is typically known as a component of bone cement, which can cause allergic reactions leading to complications like implant loosening. This differs from other treatments that focus on preventing infections or enhancing bone integration without the risk of such allergies.678910

Are You a Good Fit for This Trial?

This trial is for patients aged 18-85 who are undergoing primary hip or knee replacement at Porter Adventist Hospital without a previous joint replacement on the biopsy side. They must not have had a hip infection, be using antibiotics recently, have active psoriatic disease over the hip, Cutibacterium joint infections, or any immunodeficiency diseases.

Inclusion Criteria

I have a natural hip joint and am volunteering for research on knee or hip replacement.
CJR primary joint arthroplasty patients who are receiving care at Porter Adventist Hospital
I have not had joint replacement surgery before and am a patient at this practice.

Exclusion Criteria

I have had a hip infection in the past.
I have active psoriasis or inflammation over my hip.
I have had a total hip replacement surgery on both sides.

What Are the Treatments Tested in This Trial?

Interventions

  • Benzoyl peroxide gel
Trial Overview The study tests Benzoyl peroxide gel's effect on reducing colonization of P acnes bacteria in the skin around the hip area. This bacterium is commonly associated with acne but its role in affecting outcomes after total hip arthroplasty (hip replacement surgery) is unknown.
How Is the Trial Designed?
2Treatment groups
Experimental Treatment
Active Control
Group I: Experimental Skin Prep with BPOExperimental Treatment1 Intervention
Patients will undergo a skin cleansing protocols using 4% Chlorhexidine gluconate (CHG) cloths. Following the CHG wipes, patients will be prepped with 5% BPO gel applied directly to the biopsy site. After the skin prep, three 3-mm punch (Acu-Punch, Acuderm, Fort Lauderdale, FL) skin biopsies will performed for both an anterior-based hypothetical incision, and for a more lateral/posterior incision, for a total of 6 biopsies taken per subject.
Group II: Standard Skin PrepActive Control1 Intervention
Patients will undergo a skin cleansing protocols using 4% Chlorhexidine gluconate (CHG) cloths. After the skin prep, three 3-mm punch (Acu-Punch, Acuderm, Fort Lauderdale, FL) skin biopsies will performed for both an anterior-based hypothetical incision, and for a more lateral/posterior incision, for a total of 6 biopsies taken per subject.
