Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Most cases of human papilloma virus (HPV) infection are asymptomatic, transient and resolve without treatment. However, in some individuals, especially those patients who are immunocompromised because of various underlying diseases and those who are receiving long-term immunosuppressive agents, HPV infection is persistent and may result in genital warts, cervical smear abnormalities, cervical intraepithelial neoplasia (CIN) and rarely cervical cancer.

High-risk HPV serotypes are those which are oncogenic and associated with invasive cancers of the cervix and vulva. Examples are the HPV 16 and HPV 18. HPV 16 accounts for almost half of all cervical cancers whereas HPV 18 infection is present in 10-12% of all cervical cancers.

Systemic lupus erythematosus (SLE) patients are at risk of persistent HPV infection. This is because of the immune aberration related to the disease itself and the immunosuppressive state induced by various treatments. One study of 85 SLE patients revealed a 16.5% prevalence of abnormal Pap smears and 12% prevalence of cervical squamous intraepithelial neoplasia (CIN) on routine screening, which was significantly higher than those figures reported in age-matched healthy women (corresponding figures for abnormal Pap smear and CIN were 5.7% and 2%, respectively). Thus, prevention of HPV infection is important in patients with SLE in order to reduce the incidence of CIN lesions and hence invasive cervical cancers in the long run.

The investigators have conducted a case-control study on the safety and immunogenicity of the quadrivalent HPV vaccine, GARDASIL, in 2010. Fifty female SLE patients and 50 age-matched healthy controls were studied. At month 12 after vaccination, the sero-conversion rates of anti-HPV serotypes 6, 11, 16 and 18 in patients and controls were 82%, 89%, 95%, 76% and 98%, 98%, 98%, 80%, respectively. Injection site reaction was the commonest adverse event (AE) (5%), and the incidence of AEs was comparable between patients with SLE and controls.

The investigators plan to study the long-term immunogenicity (durability of the immune response) of the HPV vaccine in the same cohort of patients and controls followed for 5 years. In particular, in patients with SLE, the investigators would like to evaluate the effect of disease flares and ongoing immunosuppressive treatment on the immune response to the HPV serotypes 5 years after vaccination.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Neutralizing antibodies to HPV serotypes 6,11,16 and 18
Time Frame: 5 years
proportion of subjects in each arm who remains sero-converted for each HPV serotype at 5 years after vaccination
5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Neutralizing antibodies to HPV serotypes 6,11,16 and 18
Time Frame: 5 years
the change in anti-HPV titers at 5 years as compared to 12 months post-vaccination
