Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Other: Blood draw for the study participants

Detailed Description

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.

Arms and Interventions

Arm Intervention/Treatment
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

Other: Blood draw for the study participants
These will include: Procollagen 1-N propeptide levels (PINP) Matrix metalloproteinase (MMP9) Plasma Vitamin C levels

Prolapse and non smoker

Patients in this arm have been determined to have more than stage 2 pelvic organ prolapse and non smoker for more than 7 years 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

Other: Blood draw for the study participants
These will include: Procollagen 1-N propeptide levels (PINP) Matrix metalloproteinase (MMP9) Plasma Vitamin C levels

No prolapse and smoker

Patients in this arm, have been determined not to have prolapse and smokes more than 1 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

Other: Blood draw for the study participants
These will include: Procollagen 1-N propeptide levels (PINP) Matrix metalloproteinase (MMP9) Plasma Vitamin C levels

No prolapse and non smoker

Patients in this arm have been determined not to have prolapse and non smoker for more than 7 years 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

Other: Blood draw for the study participants
These will include: Procollagen 1-N propeptide levels (PINP) Matrix metalloproteinase (MMP9) Plasma Vitamin C levels

Outcome Measures

Primary Outcome Measures

  1. 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. [One day- day of blood draw]

    These will include blood levels of the following: Procollagen 1-N propeptide levels (PINP) Matrix metalloproteinase (MMP9) Plasma Vitamin C levels

Secondary Outcome Measures

  1. • A secondary objective will be to determine whether women with pelvic organ prolapse are different than healthy controls with respect to the same systemic markers [One day- day of blood draw]
