What side effects are associated with this type of intervention?

The most common treatments for osteoarthritis include nonsteroidal anti-inflammatory drugs (NSAIDs), both nonselective (e.g., ibuprofen, naproxen) and COX-2 selective inhibitors (e.g., celecoxib). Known side effects of NSAIDs include gastrointestinal issues (such as ulcers and bleeding), cardiovascular risks (such as increased risk of heart attack and stroke), and renal problems. Celecoxib, a COX-2 selective inhibitor, has a higher rate of gastrointestinal adverse effects compared to placebo. Glucosamine and chondroitin, often used in combination, are generally well-tolerated but can cause mild gastrointestinal symptoms like nausea, diarrhea, and constipation.

What prior FDA approvals exist?

FDA-approved treatments for osteoarthritis primarily include nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen, corticosteroid injections, and hyaluronic acid injections. Additionally, analgesics like acetaminophen and topical treatments such as capsaicin are also approved. For more severe cases, surgical options like joint replacement may be considered. There are no specific FDA-approved treatments for osteoarthritis that involve Propionibacterium acnes or similar bacterial colonization studies.

What other types of research exist?

Promising novel alternatives for monitoring and managing bacterial colonization in osteoarthritis patients include: 1) Advanced molecular diagnostic techniques such as 16S rRNA sequencing and metagenomic next-generation sequencing for precise identification of bacterial presence. 2) Use of antibiotic-impregnated bone cement and collagen sponges to prevent bacterial colonization during joint replacement surgeries. 3) Implementation of timely and appropriate antibiotic prophylaxis protocols to reduce the risk of surgical site infections. 4) Exploring the role of probiotics and prebiotics in modulating the skin microbiome to potentially reduce harmful bacterial colonization.

Summary

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.

Who is the study for?

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.

What is being tested?

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.

What are the potential side effects?

While not explicitly stated for this trial, Benzoyl peroxide gel typically can cause skin irritation including dryness, peeling, redness and slight swelling.

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

Other Research

The most common treatments for Osteoarthritis (OA) include analgesics, NSAIDs, and glucocorticoids. Analgesics like acetaminophen work by inhibiting the brain's pain perception pathways, providing symptomatic relief. NSAIDs, such as naproxen and ibuprofen, reduce inflammation and pain by inhibiting cyclooxygenase enzymes (COX-1 and COX-2), which are involved in the inflammatory process. Glucocorticoids, like prednisone, reduce inflammation by suppressing the immune response and decreasing the production of inflammatory mediators. These treatments are crucial for OA patients as they help manage pain and improve joint function, although they do not halt disease progression. While the study on Propionibacterium acnes focuses on bacterial colonization, it highlights the importance of understanding all factors that may impact joint health and treatment efficacy.
