BACKGROUND: Cutaneous involvement has been reported in 30-40% of children with the familial form of haemophagocytic syndrome. However, few studies have focused on cutaneous manifestations in patients with reactive haemophagocytic syndrome (RHS). OBJECTIVES: To describe the frequency, clinical features and prognosis of skin involvement in adult patients with RHS. METHODS: We conducted a retrospective study in a French university-based tertiary centre...

Immune thrombopenic purpura (ITP) is an autoimmune disease characterized by a peripheral destruction of platelets. B lymphocytes play a key role but pathophysiology is more complex, involving humoral and cellular immunity associated with an inappropriate platelet production. The treatment of ITP is still based on uncontrolled studies. Prednisone and intravenous immunoglobulins remain the first line treatments. Splenectomy remains the best "curative" treatment for adults with chronic ITP. However, most patients are reluctant to undergo surgery and new treatments give promising results...

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...

In this paper, epidemiology, pathogenesis and typical morphological aspects of all three types of membranoproliferative glomerulonephritis (MPGN), of the haemolytic uraemic syndrome (HUS) as well as of thrombotic thrombopenic purpura (TTP) will be reviewed on the light microscopical, immunohistological or immunofluorescence and electron microscopical level. In particular, differences in the pathogenesis of these diseases are discussed. Important recent molecular and genetic insights into the pathogenesis of the three types of MPGN, of typical and atypical HUS and of TTP, i...

OBJECTIVE: To investigate the hematological abnormalities and their relationship to the disease activity of systemic lupus erythematosus (SLE). METHODS: The clinical data of 236 SLE patients, 29 males and 207 females with the age of confirmed diagnosis of 33.4, were divided into 3 groups: anemia group, with the hemoglobin (Hgb) < 100 g/L, including 2 subgroups, i.e. subgroup of anemia caused by chronic diseases (ACD) and subgroup of hemolytic anemia; low white blood cell group 1 (Group WBC1) with the WBC count < 4...
