Safety Study of Two Vaccine Strategies in Patients With Systemic Lupus Erythematosus

2014-08-27 03:33:04 | BioPortfolio

Summary

The aim of this study is to compare the immunological efficacy of two pneumococcal vaccination strategies in patients with systemic lupus erythematosus (SLE) treated with corticosteroids associated or not with other immunosuppressive drugs : 1) a prime-boost strategy using vaccination with conjugate vaccine (Prevenar®) at week 0 and Poly Saccharidic vaccine (Pneumo23®) after 6 months (W24)2) compared to the standard vaccination with Poly Saccharidic vaccine (Pneumo23®) at W24 after placebo at W0

Description

Infections are more frequent and potentially more serious in patients with SLE compared to healthy subjects. This risk increases when patients are treated with corticosteroids and/or immunosuppressive drugs.Among serious infections which can happen in this context, respiratory infections are among the most frequent and Streptococcus pneumoniae is one of the most often responsible germs.Although there are no specific study in SLE, these findings indicate that patients with SLE could benefit from a preventive vaccination against pneumococcal infections.Two pneumococcal vaccines are available: Pneumo23®, a Poly Saccharidic vaccine indicated for adults and children > 2 years at risk of pneumococcal infections; and Prevenar®, a conjugate vaccine, indicated for children < 2 years.Pneumo23® has been found to be safe in SLE but less immunogenic than in general population.Prevenar® has already been studied in immunocompromised patients (HIV-infected patients, patients after renal transplantation). It has been shown that immunological efficacy is better when Prevenar® is administrated prior to Pneumo23®, compared to Pneumo23® administrated alone.To our knowledge, this prime-boost strategy has not been assessed in patients with SLEThe primary objective of the study is to compare immunological efficacy of two pneumococcal vaccination strategies in patients with systemic lupus erythematosus (SLE) treated with corticosteroids associated or not with other immunosuppressive drugs : 1) Vaccination with conjugate vaccine (Prevenar®) at week 0 and Poly Saccharidic vaccine (Pneumo23®) after 6 months (W24)2) Vaccination with placebo at W0 and Poly Saccharidic vaccine (Pneumo23®) at W24Secondary objectives are:

- To compare the clinical and biological tolerance of the two vaccinal strategies·

- To evaluate the durability of sero protection at 6 and 24 months after vaccination by Pneumo23®

- To search predictive factors determinant of the pneumococcal vaccine response

Medical and Biotech [MESH] Definitions

A form of lupus erythematosus in which the skin may be the only organ involved or in which skin involvement precedes the spread into other body systems. It has been classified into three forms - acute (= LUPUS ERYTHEMATOSUS, SYSTEMIC with skin lesions), subacute, and chronic (= LUPUS ERYTHEMATOSUS, DISCOID).

A chronic form of cutaneous lupus erythematosus (LUPUS ERYTHEMATOSUS, CUTANEOUS) in which the skin lesions mimic those of the systemic form but in which systemic signs are rare. It is characterized by the presence of discoid skin plaques showing varying degrees of edema, erythema, scaliness, follicular plugging, and skin atrophy. Lesions are surrounded by an elevated erythematous border. The condition typically involves the face and scalp, but widespread dissemination may occur.

Antiphospholipid antibodies found in association with systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC;), ANTIPHOSPHOLIPID SYNDROME; and in a variety of other diseases as well as in healthy individuals. The antibodies are detected by solid-phase IMMUNOASSAY employing the purified phospholipid antigen CARDIOLIPIN.

Autoantibodies directed against phospholipids. These antibodies are characteristically found in patients with systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC;), ANTIPHOSPHOLIPID SYNDROME; related autoimmune diseases, some non-autoimmune diseases, and also in healthy individuals.

An antiphospholipid antibody found in association with systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC;), ANTIPHOSPHOLIPID SYNDROME; and in a variety of other diseases as well as in healthy individuals. In vitro, the antibody interferes with the conversion of prothrombin to thrombin and prolongs the partial thromboplastin time. In vivo, it exerts a procoagulant effect resulting in thrombosis mainly in the larger veins and arteries. It further causes obstetrical complications, including fetal death and spontaneous abortion, as well as a variety of hematologic and neurologic complications.
