Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Data on smoking and POP are conflicting. In a study done by Alnaif et al, smoking was found to be associated with severe POP. The authors' proposed explanation was that smoking impairs tissue and wound healing. Our primary objective is to document whether smokers with pelvic organ prolapse (POP) are different from non-smokers with POP with respect to collagen biosynthesis and breakdown using systemic markers of collagen metabolism and Vitamin C.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Tissue destructive disorders are more common in smokers than in non-smokers. Alterations in wound healing and connective tissue turnover are suggested mechanisms, but exact details remain to be discovered. The synthesis of subcutaneous collagen in smokers is specifically impeded, and that smokers have less collagen compared to non-smokers. Jorgensen et al study showed that smokers tend to have less procollagen I N-propeptide (PINP) levels in the blood, less vitamin C and higher levels of matrix metalloproteinase (MMP-9), these findings reversed after smoking cessation.

Since smoking is one of the promoting and modifiable factors in the development of prolapse, understanding its effects on the support of pelvic organs may help modify the course of the POP condition in the future. Understanding the connective tissue effects of smoking using systemic markers of collagen metabolism in female smokers with prolapse may help future management and counseling of these patients. In addition, description of the markers of collagen metabolism in POP has not previously been documented.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Prolapse and Smoker

Patients in this arm have been determined to have more than stage 2 pelvic organ prolapse and have been smoking more than one pack per day Blood draw for the study participants will be done. These will include: Procollagen 1-N propeptide levels (PINP), Matrix metalloproteinase (MMP9) and Plasma Vitamin C levels
