Brief Summary:
The primary purpose of the study is to describe by a prospective observational study the serious adverse events occurring in patients treated off-label by rituximab for Immune Thrombocytopenia.

Condition or disease
Purpura, Thrombocytopenic, Idiopathic Autoimmune Thrombocytopenia

Detailed Description:

Rituximab (RTX) is used in the treatment of malignant non-Hodgkin's indication for which it has been authorized since 1997 and why it is considered effective and well tolerated. Rituximab is also effective and well tolerated in combination with methotrexate in severe rheumatoid arthritis (RA) refractory to anti-TNF. To date, the RA is the only autoimmune disease in which rituximab has proven efficacy in randomized trials and has obtained authorization in this indication. There are also data from the literature, for the benefit of rituximab in other autoimmune diseases like Lupus, cryoglobulinemia associated to Hepatitis C or Sjogren's disease.

Immune Thrombocytopenia (ITP) is an autoimmune disease in which there is thrombocytopenia due in part to destruction of platelets by autoantibodies. In adults, the disease is most often chronic and in the most severe forms, the treatment of choice is splenectomy. Rituximab was suggested during chronic ITP when used with 4 weekly infusions of 375 mg/m2, 60% of patients achieve an immediate response and 30 to 40% a prolonged response. These encouraging results and the apparent good tolerance advocate for using rituximab as first-line treatment for patients refractory to splenectomy. In France, Afssaps - French Health Products Safety Agency has recently issued a temporary protocol processing to authorize rituximab in this indication. Nevertheless, many questions remain unresolved, including the tolerance of long-term treatment and the risk of late relapse in responders. This justifies the creation of this register, whose establishment is recommended by Afssaps - French Health Products Safety Agency.

Primary Outcome Measures :
  1. Occurrence of a serious adverse events (clinical or biological events) [ Time Frame: 5 years ]
    reaction during perfusions, hypogammaglobulinemia, neutropenia,etc...

Secondary Outcome Measures :
  1. Impact of rituximab on the natural history of ITP [ Time Frame: 5 years ]

    Number of patients in complete response (platelet count>100G/L), in partial response (platelet count>50G/L and at least doubling the baseline platelet count)or in failure. Rate of diminution for the concomittant therapies for ITP.

    Use of emergencies treatment for ITP.

  2. Modality of the administration of rituximab [ Time Frame: 5 years ]
    number of perfusions, dosage, retreatment.

  3. Characteristics of the patients receiving Rituximab [ Time Frame: 5 years ]
    age, sex, duration of ITP, previous used treatment

  4. Evaluation of the Platelet count evolution [ Time Frame: 5 years ]
    Platelet count estimated at Month 1, 3 and then every 6 months during the 5 years of follow-up.

  5. Rate of splenectomy in the cohort [ Time Frame: 5 years ]
