Finasteride and Cutibacterium
High levels of Testosterone causes high amounts of skin bacteria (Cutibacterium Acnes) which can go into the skin during a shoulder replacement surgery and cause a terrible infection.
The goal of this experiment is to have participants take Finasteride, a medication that blocks testosterone production, for 2 weeks and evaluate the following:
- Blood levels of testosterone
- Amount of bacteria on the skin.
Participants will:
- Be assigned to take Finasteride, or a placebo (a look-alike pill with no active medicine) once daily, for 2 weeks
- Have a small sample of their blood collected and their skin swabbed with a Q-tip to determine Testosterone levels and bacteria on the skin
- Blood draw and skin testing will take place before starting Finasteride or the placebo (day 0) and at the end of the experiment (day 14).

主要结果指标

措施说明 |
大体时间 |
|---|---|---|
|
Cutibacterium skin load
大体时间：Skin load will be assessed at day 0 and at the end of the study on day 14 of treatment or placebo.
|
Skin load will be determined using bacterial culture of the skin and assigning a value based on the report from the microbiology lab: 0 for "no growth"; 0.1 for "growth of 1 colony only" or for "growth in broth only"; and 1, 2, 3 and 4 for 1+, 2+, 3+ and 4+ growth, respectively. Mann-Whitney U test will be used to compare the change in the semi-quantitative skin load at baseline and day 14 in the intervention and control group, along with comparison of the percentage of subjects in each group that began with a high baseline skin load (>2) and ended with a low skin load (≤1). |
Skin load will be assessed at day 0 and at the end of the study on day 14 of treatment or placebo.
|
|
Serum Dihydrotestosterone (DHT) Level
大体时间：levels will be assessed at baseline and after 14 consecutive days of treatment or placebo.
|
Participants blood will be collected and processed for serum DHT level by the certified and state-licensed phlebotomists and clinical laboratory technicians at our intuition, which is in the same building as the outpatient clinic.
|
levels will be assessed at baseline and after 14 consecutive days of treatment or placebo.
