Collagen type 3A1 and 1A1 polymorphisms in women with pelvic organ prolapse and urinary incontinence assessed with Sanger sequencing method.

ABSTRACT:

Introduction

This case-control trial investigates the prevalence of COL3A1 and COL1A1 gene polymorphisms in female patients suffering pelvic organ prolapse (POP) and stress urinary incontinence (SUI) in comparison with controls.

Material and methods

Inclusion criteria were having one or more risk factors for SUI and POP. Exclusion criteria were hereditary connective tissue diseases as well as surgeries for POP/SUI for the control group. The rs1800255 polymorphism in COL3A1 gene was considered as a local substitution of guanine (G) for adenine (A). The rs1800012 polymorphism in COL1A1 gene was considered as a local substitution of guanine (G) for thymine (T). Genotyping was performed by Sanger sequencing method, followed by estimation of sensitivity and specificity for POP and SUI.

Results

Fifty-two patients with POP and SUI (mean age 64.4 years) and 21 women were included in the control group (mean age 63.2 years). Homozygous genotype (AA) in COL3A1 was found in 10% of patients suffering from POP or SUI. No women in the control group had this genotype. The single nucleotide polymorphism (SNP) had high specificity (1.0) for POP/SUI, but low sensitivity (0.1). Heterozygous genotype (AG) in COL3A1 had a sensitivity equal to 0.47 and specificity of 0.62. Homozygous genotype (TT) in COL1A1 was found in only 2% of patients with POP/SUI, but was not found in controls. Heterozygous genotype (TG) in COL1A1 has sensitivity equal to 0.25 and specificity of 0.74.

Conclusions

POP/SUI patients have specific SNPs in COL1A1 and COL3A1 sequenced by Sanger method.

Project description:BackgroundLittle is known about short- and long-term pain and functional activity after surgery for pelvic organ prolapse.ObjectiveThe objectives of the study were to describe postoperative pain and functional activity after transvaginal native tissue reconstructive surgery with apical suspension and retropubic synthetic midurethral sling and to compare these outcomes between patients receiving 2 common transvaginal prolapse repairs, uterosacral ligament, and sacrospinous ligament vaginal vault suspension.Study designThis planned secondary analysis of a 2 × 2 factorial randomized trial included 374 women randomized to receive uterosacral (n = 188) or sacrospinous (n = 186) vaginal vault suspension to treat both stages 2-4 apical vaginal prolapse and stress urinary incontinence between 2008 and 2013 at 9 medical centers. Participants were also randomized to receive perioperative pelvic muscle therapy or usual care. All patients received transvaginal native tissue repairs and a midurethral sling. Participants completed the Surgical Pain Scales (0-10 numeric rating scales; higher scores = greater pain) and Activity Assessment Scale (0-100; higher score = higher activity) prior to surgery and at 2 weeks, 4-6 weeks, and 3 months postoperatively. The MOS 36-item Short-Form Health Survey was completed at baseline and 6, 12, and 24 months after surgery; the bodily pain, physical functioning, and role-physical subscales were used for this analysis (higher scores = less disability). Self-reported pain medication use was also collected.ResultsBefore surgery, average pain at rest and during normal activity were (adjusted mean ± SE) 2.24 ± 0.23 and 2.76 ± 0.25; both increased slightly from baseline at 2 weeks (+0.65, P = .004, and +0.74, P = .007, respectively) and then decreased below baseline at 3 months (-0.87 and -1.14, respectively, P < .001), with no differences between surgical groups. Pain during exercise/strenuous activity and worst pain decreased below baseline levels at 4-6 weeks (-1.26, P = .014, and -0.95, P = .002) and 3 months (-1.97 and -1.50, P < .001) without differences between surgical groups. Functional activity as measured by the Activity Assessment Scale improved from baseline at 4-6 weeks (+9.24, P < .001) and 3 months (+13.79, P < .001). The MOS 36-item Short-Form Health Survey Bodily Pain, Physical Functioning, and Role-Physical Scales demonstrated significant improvements from baseline at 6, 12, and 24 months (24 months: +5.62, +5.79, and +4.72, respectively, P < .001 for each) with no differences between groups. Use of narcotic pain medications was reported by 14.3% of participants prior to surgery and 53.7% at 2 and 26.1% at 4-6 weeks postoperatively; thereafter use was similar to baseline rates until 24 months when it decreased to 6.8%. Use of nonnarcotic pain medication was reported by 48.1% of participants prior to surgery, 68.7% at 2 weeks, and similar to baseline at 3 months; thereafter use dropped steadily to 26.6% at 2 years. Uterosacral ligament suspension resulted in less new or worsening buttock pain than sacrospinous suspension at 4-6 weeks postoperatively (4.6% vs 10.5%, P = .043) but no difference in groin or thigh pain.ConclusionPain and functional activity improve for up to 2 years after native tissue reconstructive surgery with uterosacral or sacrospinous vaginal vault suspension and midurethral sling for stages 2-4 pelvic organ prolapse. On average, immediate postoperative pain is low and improves to below baseline levels by 4-6 weeks.

Project description:BackgroundThere is an opioid epidemic in the United States with a contributing factor of opioids being prescribed for postoperative pain after surgery.ObjectiveAmong women who underwent stress urinary incontinence and pelvic organ prolapse surgeries, our primary objective was to determine the proportion of women who filled perioperative opioid prescriptions and to compare factors associated with these opioid prescriptions. We also sought to assess the risk of prolonged opioid use through 1 year after stress urinary incontinence and pelvic organ prolapse surgeries.Study designUsing a population-based cohort of commercially insured individuals in the 2005-2015 IBM MarketScan databases, we identified opioid-naive women ≥18 years who underwent stress urinary incontinence and/or pelvic organ prolapse procedures based on Current Procedural Terminology codes. We defined the perioperative period as the window beginning 30 days before surgery extending until 7 days after surgery. Any filled opioid prescription in this window was considered a perioperative prescription. For our primary outcome, we reported the proportion of opioid-naive women who filled a perioperative opioid prescription and reported the median quantity dispensed in the perioperative period. We also assessed demographic and perioperative factors associated with perioperative opioid prescription fills. Previous studies have defined prolonged use as the proportion of women who fill an opioid prescription between 90 and 180 days after surgery. We report this estimate as well as continuous opioid use, defined as the proportion of women with ongoing monthly opioid prescriptions filled through 1 year after stress urinary incontinence and/or pelvic organ prolapse surgery.ResultsAmong the 217,460 opioid-naive women who underwent urogynecologic surgery, 61,025 (28.1%) had pelvic organ prolapse and stress urinary incontinence surgeries, 85,575 (39.4%) had stress urinary incontinence surgery without pelvic organ prolapse surgery, and 70,860 (32.6%) had pelvic organ prolapse surgery without stress urinary incontinence surgery. Overall, 167,354 (77.0%) filled a perioperative opioid prescription, and the median quantity was 30 pills (interquartile range, 20-30). In a multivariate regression model, younger age, pelvic organ prolapse surgery with or without stress urinary incontinence surgery, abdominal route, hysterectomy, and mesh use remained significantly associated with opioid prescriptions filled. Among those with a filled perioperative opioid prescription, the risk of prolonged use defined as an opioid prescription filled between 90 and 180 days was 7.5% (95% confidence interval, 7.3-7.6). However, the risk of prolonged use defined as continuous use with at least 1 monthly opioid prescription filled after surgery was significantly lower: 1.2% (1.13-1.24), 0.32% (0.29-0.35), 0.06% (0.05-0.08), and 0.04% (0.02-0.05) at 60, 90, 180, and 360 days after surgery, respectively.ConclusionAmong privately insured, opioid-naive women undergoing stress urinary incontinence and/or pelvic organ prolapse surgery, 77% of women filled an opioid prescription with a median of 30 opioid pills prescribed. For prolonged use, 7.5% (95% confidence interval, 7.3-7.6) filled an opioid prescription within 90 to 180 days after surgery, but the rates of continuously filled opioid prescriptions were significantly lower at 0.06% (95% confidence interval, 0.05-0.08) at 180 days and 0.04% (95% confidence interval, 0.02-0.05) at 1 year after surgery.
