Comparison of an intravenous pulse of methylprednisolone versus oral corticosteroid in severe acute rheumatic carditis: a randomized clinical trial

OBJECTIVES: To compare the short-term prognosis of patients with severe acute rheumatic carditis when treated with an intravenous pulse of methylprednisolone in comparison with conventional treatment using oral prednisone. METHODS: We designed a randomized clinical trial in the setting of a university general hospital in Brazil. We randomly allocated 18 patients with the diagnosis of severe acute rheumatic carditis and congestive heart failure to receive an intravenous pulse as opposed to oral prednisolone. Methylprednisolone was administered in a dose of 1 g intravenously for 3 consecutive days in the first and second weeks, for two days in the third, and one day in the fourth week. Prednisone was administered in a dose of 1.5 mg/kg/day over the period of 4 weeks. RESULTS: The mean age of the patients was 11.1 +/- 3.7 years, with a median of 12 years. Patients on oral treatment showed a more pronounced decrease in the heart rate, sedimentation rate, and in the titres of C-reactive protein than those receiving intravenous therapy. At the end of treatment, a mild decrease in the left ventricular end-systolic dimension was found in those having oral treatment, compared to an increase in the group having intravenous treatment (p = 0.036). The ejection fraction showed a median increase of 5% in those undergoing oral treatment, and a median decrease of 6% in the group with intravenous therapy (p = 0.009). There were 5 therapeutic failures in those receiving intravenous therapy (56%), including 1 death. Therapeutic failures were not observed in those treated orally (p = 0.03). CONCLUSION: Intravenous treatment of methylprednisolone, as a single anti-inflammatory agent, was inferior to conventional treatment with oral prednisone in the control of severe rheumatic carditis.     

Implication of emergency departments in the regulation of public hospitalizations

PURPOSE: Emergency departments become a useful way to access to hospital care. Since these last years difficulties of hospitalization, mainly of the elderly, after visit to the emergency department, are on the increase. CURRENT KNOWLEDGE AND KEY POINTS: Emergency departments are an important mode of recruitment for hospital units, 4 patients to 10 are hospitalized from emergency departments. The difficulties of hospitalization starting at the emergency department are more important for the elderly. Actually, there are 2 type of hospital care, planed and non planed care. The development of observation units specific to the emergency departments allowed to resolve some of these difficulties. But they are limited by their small number of beds and the duration of hospitalization below to 36 h. Some hospitals developed polyvalent emergency short stay unit to hospitalize patients who visited emergency department without necessity to give them a specialized care. FUTURE PROSPECTS AND PROJECTS: This situation must allow us to purpose a better regulation of hospitalizations which includes emergency departments in a network system including the different hospital ways of taking care. A downstream way of care adapted to the emergency hospitalizations would be developed. This could include the emergency department, the observation unit and the emergency short stay unit in interface with internal medicine and general medicine units, geriatric unit and specialized units, all of them will be included in a town-hospital care network.     

Sphingolipid signalling and liver diseases.

Sphingolipids (SLs) comprise a class of lipids with important structural functions and increasing relevance in cellular signalling. In particular, ceramide has attracted considerable attention owing to its role as a second messenger modulating several cell functions such as proliferation, gene expression, differentiation, cell cycle arrest and cell death. Increasing evidence documents the role of SLs in stress and death ligand-induced hepatocellular death, which contributes to the progression of several liver diseases including steatohepatitis, ischaemia-reperfusion liver injury or hepatocarcinogenesis. Furthermore, recent data indicate that the accumulation of SLs in specific cell subcompartments, characteristic of many sphingolipidoses, contributes to the hepatic dysfunctions that accompany these inherited diseases. Hence, the regulation of the cell biology and metabolism of SLs may open up a novel therapeutic avenue in the treatment of liver diseases.     

Long-term outcome of allogeneic or autologous haemopoietic cell transplantation for acute lymphoblastic leukaemia in second remission in children. GETMON experience 1983-1998

We present a retrospective study of long-term outcome and predictive factors of survival and relapse in 219 paediatric patients with acute lymphoblastic leukaemia (ALL) in second remission. They received allogeneic (allo) or autologous (auto) haemopoietic cell transplantation (HCT) depending on the availability of a matched sibling donor. The probability of event-free survival (EFS) for the total patient group was 0.35+0.03 at 14 years. No significant differences were observed for EFS between allo- and auto-HCT: 0.39+0.05 vs 0.32+0.04 (P=0.43). A better EFS was seen in patients with a late relapse (LR) (P=0.06 and 0.02, for allogeneic and autologous respectively). Significantly better EFS was observed in allo-HCT patients under 10 years of age and in auto-HCT patients with leukocytes at diagnosis below 25 x 109/l and late relapse. Predictive factors of failure in both groups were early relapse (ER), medullary relapse and age over 10 years. The probability of relapse (RP) for the total group of patients was 0.57+0.03, and it was significantly higher in auto-HCT patients: 0.65+0.04 vs 0.42+0.06 (P=0.002). Factors predictive for relapse were medullary and early relapse, auto-HCT and WBC >25 x 109/l at diagnosis.     

Ventricular patch endocarditis caused by Propionibacterium acnes: advantages of gallium scanning

Propionibacterium acnes is a weakly pathogenic commensal of the skin. When isolated from blood cultures it is often considered a contaminant. However, P. acnes may be responsible for severe infections and its role in certain cases of infectious endocarditis has now been definitely established.(1) We report a case of endocarditis due to P. acnes stemming from a ventricular patch and revealed by a gallium 67 scan.
