Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is about a multicentric study prospective of more than patients' 60 years with a thrombopenia isolated of less than 100 G/L blood platelet without cause found to estimate so certain examinations realized in the diagnosis (medullary cytogenetics, dosage of the TPO, the Anti-platelet antibodies, isotopic lifetime of platelet) are in favour of the diagnosis of PTI.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is about a multicentric study prospective of more than patients' 60 years with a thrombopenia isolated of less than 100 G/L blood platelet without cause found to estimate so certain examinations realized in the diagnosis (medullary cytogenetics, dosage of the TPO, the Anti-platelet antibodies, isotopic lifetime of platelet) are in favour of the diagnosis of PTI.

The principal endpoint is to evaluate if the medullary cytogenetics is the predictive factor of the diagnosis of PTI in front of a thrombopenia isolated in elderly.

The secondary endpoints are :

* to identify at the time of the diagnosis, the factors and/or predictive markers correlated in the final diagnosis of PTI or SMD
* to study the respective frequency of the PTI and the SMD in front of a thrombopenia seemingly isolated of the subject of more than 60 years.

200 patients will be included. 160 patients should be assessable at the end of study by considering the excluded patients, the dead and the lost sight.They will be followed every 4 months, during two years.

In every visit, will be realized a clinical examination, a blood film, a haemogram.

If the haemogram is abnormal, a bone marrow biopsy is realized. The patient who presents a myelodysplastic syndrome is excluded.

Study Groups

patients with a thrombopenia isolated

Patients of 60 years old and more presenting a thrombopenia isolated with a rate of platelet \< 100 G/l Blood tests and bone marrow biopsy repeated

Group Type OTHER

Blood tests and bone marrow biopsy repeated

Intervention Type OTHER

Blood tests are realized for the dosage of the TPO, the dosage of the antiplatelet antibodies, to measure isotopic lifetime of platelet.

The test in corticoids by the prednisone per os is realized too. The bone marrow biopsy is realized at the inclusion and during follow-ups if the haemogram is abnormal.
