Brief Summary:
The purpose of this study is to evaluate the immunogenicity and safety of the HPV vaccine Gardasil in young women.

Condition or disease Intervention/treatment Phase
Systemic Lupus Erythematosus Biological: Gardasil Not Applicable

Detailed Description:

Female patients with systemic lupus erythematosus (SLE) have been found have higher rates of persistent HPV infections and precancerous lesions compared to the healthy population. The HPV vaccine Gardasil has been found to be safe and efficacious in females aged 9 to 26 years. There are no data on the immunogenicity and safety of Gardasil in females with SLE. Immune dysfunction related to SLE itself and the immunosuppression secondary to treatment of SLE might prevent patients with SLE from developing an adequate immune response to the vaccine. Also, theoretically, the vaccine might induce a disease exacerbation or production of new autoantibodies.

The purpose of this study is to evaluate immunogenicity and safety of Gardasil and its effects on autoantibody profile in female SLE patients aged 9-26 years

Arm Intervention/treatment
Gardasil
30 patients will receive 0.5 ml Gardasil vaccine at months 0,2, and 6.
Biological: Gardasil
0.5 ml Gardasil vaccine will be administered to each patient at months 0,2 and 6.




Primary Outcome Measures :
  1. Anti-HPV 6 Seroconversion [ Time Frame: 7 months ]
    Percent Seropositive

  2. Anti-HPV 6 GMT [ Time Frame: 7 months ]
    Geometric mean titre in milli-Merck units per ml (mMu/ml)

  3. Anti-HPV 11 Seroconversion [ Time Frame: 7 months ]
    % Seropositive

  4. Anti-HPV 11 GMT [ Time Frame: 7 months ]
    Geometric mean titre in milli-Merck units per ml (mMu/ml)

  5. Anti-HPV 16 Seroconversion [ Time Frame: 7 months ]
    % Seropositive

  6. Anti-HPV 16 GMT [ Time Frame: 7 months ]
    Geometric mean titre in milli-Merck units per ml (mMu/ml)

  7. Anti-HPV 18 Seroconversion [ Time Frame: 7 months ]
    % Seropositive

  8. Anti-HPV 18 GMT [ Time Frame: 7 months ]
    Geometric mean titre in milli-Merck units per ml (mMu/ml)

  9. SLEDAI Change Score [ Time Frame: 7 months ]
    Systemic Lupus Erythematosus Disease Activity Index (SLEDAI): change from baseline to 7 months. The SLEDAI scale is a weighted sum of 16 clinical and 8 laboratory items. Scores range from 0 to 105 with higher scores indicating worse outcome. The variable analyzed here is the 7 month score minus the baseline score. Therefore negative values indicate an improvement in outcome.


Secondary Outcome Measures :
  1. Induction or Increase of Autoantibodies (Conversion From Negative Anti-RNP to Positive Anti-RNP) Anti-RNP [ Time Frame: 7 months ]
  2. Induction or Increase of Autoantibodies (Conversion From Negative Smith to Positive Smith) [ Time Frame: 7 months ]
  3. Induction or Increase of Autoantibodies (Conversion From Lupus Anticoagulant Negative to Lupus Anticoagulant Positive) [ Time Frame: 7 months ]
