About this study

Official title: Genotypification and Predisposing Factors in Human Papilloma Virus Infection and Its Association With the Carbohydrate Antigen (CA-125) Tumoral Marker

Objective: Determine the genotypes and risk factors associated with human papilloma virus infection in Mexican women.

Methods: It was a cross-sectional study of women attended at the Materno-Perinatal Hospital "Mónica Pretelini" and the Medical Research Center (CICMED), who were asked to complete a risk factor questionnaire and submitted to colposcopy to identify SIL. Cervical swab samples were obtained to perform linear array HPV genotyping test (Roche®, Mannheim, Germany).

Read the detailed description

Principles: The aim of this study was to determine the HPV genotypes in squamous intraepithelial lesions (SIL) in a population sample of the State of Mexico.

Patients:

The inclusion criteria were women submitted to a colposcopy study at the Clinic 221 of the Mexican Social Security Institute (IMSS), Maternal-Perinatal Hospital "Monica Pretelini" (HMPMP), State of Mexico Health Institute (ISEM) and the Medical Research Center (CICMED), Autonomous University of State of México (UAEMex). Women with previous conization were not considered into the study and those whose clinical follow up was lost were excluded.

Sociodemographic factors:

Patients were given a questionnaire to measure the following potential risk factors: age, area of residence, education level, sexual partners, participation in anal sex, age at first intercourse, smoking, use of hormonal contraception, use of condoms, number of pregnancies and vaginal deliveries.

Cervical samples:

Samples were collected by cervical scraping and were preserved in ThinPrep® PreservCyt® Solution (HologicTM Marlborough, Massachusetts, USA).

HPV genotyping:

DNA extraction from the cervical swab samples was performed using the Amplicor kit (Roche®, Mannheim, Germany), isolating simultaneously the β-globin gene along with HPV. HPV positive specimens were subsequently genotyped using the Linear Array HPV Genotyping assay (Roche®, Mannheim, Germany). This test is a qualitative in vitro test for the detection of HPV utilizing amplification of target DNA by the Polymerase Chain Reaction (PCR) and nucleic acid hybridization able to detect 37 anogenital HPV DNA genotypes (6, 11, 16, 18, 26, 31, 33, 35, 39, 40, 42, 45, 51, 52, 53, 54, 55, 56, 58, 59, 61, 62, 64, 66, 67, 68, 69, 70, 71, 72, 73 (MM9), 81, 82 (MM4), 83 (MM7), 84 (MM8), IS39 and CP6108). This technique can detect multiple HPV genotypes in the same sample.

Ethical concerns:

We followed the Declaration of Helsinki and all patients were asked to sign the written informed consent. This study was accepted by the Research and Ethical Committee of the CICMED.

Statistical analysis:

First, descriptive analyzes were performed, secondly, Odds Ratios (OR) and their associated 95% confidence intervals (95% CI) were calculated as well as Chi-square tests and conditional regression model for SIL using the Statistical Package for the Social Sciences (SPSS) 17.0 software. Difference was considered significant at p ≤ 0.05.

Linear Array HPV Genotyping assayNo interventionWomen submitted to colposcopy with a suspicion of squamous intraepithelial lesion were programmed a clinical follow up to cervical swab in order to extract DNA and perform a Linear Array HPV Genotyping assay (Roche®, Mannheim, Germany).
Receives: Other: Linear Array HPV Genotyping assay

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Multiple HPV infection

    While women are revised by colposcopy the Gynecologist will refer them to a cervical swab for DNA extraction in case of suspicious of HPV infection.

    Measured: At the moment of the colposcopy

Secondary outcomes (1)
  1. squamous intraepithelial lesions

    The pathologist will determine the presence or absence of SIL with the sample taken in the Papanicolaou smear appointment

    Measured: Within one week after the cervical sample taken by the technician

Questions about this trial

What is this clinical trial studying?

A study testing Linear Array HPV Genotyping assay in people with Intraepithelial Neoplasia, run by Materno-Perinatal Hospital of the State of Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Multiple HPV infection (time frame: At the moment of the colposcopy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2013.
