About this study
Official title: Safety and Efficacy of Vaccination Against Influenza in Patients With Scleroderma
The safety and efficacy of vaccination against influenza in patients with scleroderma is not clear. The objective of this study is to assess its safety and efficacy in 50 patients with scleroderma in comparison with 30 controls
Read the detailed description
Fifty patients with scleroderma and 30 healthy , aged matched controls will participate in the study.
After signing informed consent, all subjects will be vaccinated with the inactivated split virion vaccine which recommended by the WHO this fall.
Patients will be evaluated at weel 0 and 6 weeks later. Clinical evaluation will be based on the modified Rodnan score, number of digital ischemic ulcers, presence of gastrointestinal and respiratory symptoms, number of swollen and tender joints, visual global evaluation of the physician , ESR and CRP Blood with be collected on the day of vaccination and 6 weeks later.
The immunogenicity of the vaccine will be tested by Haemagglutination inhibition (HI) test.
Influenza virus has two important surface glycoproteins: the haemagglutinin (HA) and the neuraminidase (NA). Antigenic classification and subtyping of influenza viruses is based on these two glycoproteins. HA plays a key role in virus cell entry by binding to cell surface receptors, which are found also on red blood cells of certain species. Binding to red cells results in haemagglutination, which can be observed as a carpet of agglutinated red cells at the bottom of a tube or microtitre well. In the HI test, antibody directed against the viral haemagglutinins block the virus from binding to the blood cells and thus inhibits the haemagglutination reaction.
The pre- and post immunization HI antibodies were tested at the Central Virology Laboratory of the Israeli Ministry of Health using the HI test according to a standard WHO procedure 16. Sera were separated, code labeled, and stored at -20°C until tested. Sera were treated with receptor destroying enzyme cholera filtrate to remove non-specific inhibitors, and with Turkey red blood cells to remove non-specific agglutinins. The treated sera were tested by HI test against the three antigens included in the vaccine: A/California (CAL), A/Wisconsin and B/Malaysia. The working dilution (test dose) of each antigen contained four haemagglutinin units in 25 µl of antigen. Test doses were diluted in phosphate buffered saline (PBS) and added to serial dilution of antiserum. The haemagglutinin inhibition titer was determined as the highest dilution of serum that completely inhibits haemagglutination of red blood cells.
The titer of an antiserum not showing any inhibition will be recorded as <10. Humoral response will be defined as either a fourfold or more rise in titer, or a rise from a non-protective baseline level of <1/40 to 1/40 in HI antibodies four weeks after vaccination 17,18. Geometric mean titers of antibody will be calculated to assess the immunity of the whole group.
Primary Endpoint of the study : the proportion of patients who achieve a titer of antibodies above 1/40, against each of the antigens included in the vaccine Secondary Endpoint: Safety of the vaccine

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 3 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 27 Oct 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ira Litinsky, MD (97236873668, orie@tasmc.health.gov.il), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number of subjects who achieve a titer of antibodies above 1/40 (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01002508, which also lists 1 linked publication.
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 27 Oct 2009.
