immunologic purpura thrombopenic

INTRODUCTION: Castleman's disease is a rare orphan disease. The prevalence is estimated at less than 1/100 000. Respirologists may encounter this disease when its thoracic manifestations occur. CASE REPORT: The authors report two cases of Castleman's disease with two different thoracic involvements. The first patient was a 20-year-old man without a previous medical history. A chance chest X-ray revealed right basal opacity. A lung biopsy demonstrated giant lymph node polyclonal hyperplasia leading to the diagnosis of a thoracic form of Castleman's disease...

We report one case of thrombocytopaenia purpura associated with an auto-immune haemolytic anaemia (positive erythrocyte Coombs test) or Fisher-Evans syndrome, found in a child aged 6 and a half years. Etiopathogenic, clinical, therapeutic as well as evolutive aspects are discussed. Response to corticoids is satisfactory in case our patient, in opposite to most cases described in the literature.

Acquired Toxoplasma Gondii infection has a benign course in adults and children immunologically competent. Thrombocytopenia is much more common during congenital toxoplasma infection and the rare cases of purpura associated with acquired toxoplasmosis are usually not thrombocytopenic. We report a case of thrombocytopenic purpura in an immunocompetent child, associated with active acquired toxoplasmosis. In rare circumstances, acquired toxoplasmosis in an immunocompetent patient may be associated with severe thrombocytopenia...

UNLABELLED: We report a series of 27 patients included on the basis of either thrombotic microangiopathy (TMA) at renal histology (13 cases) or, in the absence of histology, non-immunological hemolytic anemia with schizocytes and thrombopenia (14 cas). The etiopathogenic treatment consisted in the administration of antiagregating agents (in all patients except 3 of group I because of the severity of thrombopenic), corticosteroids (1 case), intravenous immunoglobulins (2 cases) fresh frozen plasma (FFP) without plasma exchange (PE) in 7 cases and PE with FFP in 13 patients...

Synchronization is defined as a prescription sequence aimed at obtaining synergic response or potentialization. THEORETICAL BASIS--The concept of synchronization is based on clinical and biological observations such as similar indications and transient effectiveness. Certain mechanisms of action such as reduction of pathological autoantibodies and accelerated elimination of immune complexes are common to both methods. Inversely, long-term effects differ. Plasma exchange cannot control the synthesis (or could aggravate) of autoantibodies while gammaglobulins have a suppressor effect on autoreactive clones...

Immunologic thrombopenic purpura refers to several diseases including the most frequent, autoimmune thrombopenic purpura (AITP). Immunologic thrombopenia is related to anti-platelet autoantibodies, usually IgGs. In 15 to 20% of the cases, no auto-antibody can be detected. The severity of the cutaneomucosal manifestations is not always correlated with the degree of thrombopenia but only occurs for platelet counts less than 50 x 10(9)/L. The clinical course includes acute episodes of AITP and complete remissions in 80% of the cases in the episodes of AITP and complete remissions in 80% of the cases in the very young child...

We report the second case of Hodgkin's disease associated with thrombotic thrombocytopenic purpura (TTP). Although the two diseases coexisted originally, TTP was diagnosed alone at first. Because of the very rare occurrence of this association the diagnosis of TTP is discussed according to the accepted criteria and taking into account the haematological complications which can reveal or be observed in Hodgkin's disease. No evident relationship between the two diseases can be suggested. But immunologic disorders observed in the two cases suggests that their coexistence is not necessarily accidental...

In a 29-year-old man with primary thrombotic-thrombocytopenic purpura a significantly increased plasma concentration of platelet-specific proteins was demonstrated as an expression of increased intravascular platelet activation and destruction during the acute phase of the disease. There was also abnormally elevated IgG loading of platelets. During administration of fresh plasma alone (total of six litres over one week) the clinical state deteriorated further into coma and failure of spontaneous ventilation...
