Perfluorocarbons have been shown to reduce the inflammatory process generated by alveolar macrophages in vitro. The aim of this study was to evaluate the impact of different ventilator modalities such as partial liquid ventilation (PLV), conventional ventilation (CV), and high-frequency oscillatory ventilation (HFOV) on the release of inflammatory mediators in vivo. Acute lung injury was induced in 30 male piglets by repeated saline lavage (arterial oxygen tension, <60 mm Hg; fraction of inspired oxygen, 1.0). Thereafter, animals were randomly assigned to one of five groups of six animals each: 1) 24 h of CV; 2) 24 h of CV plus surfactant therapy (S+CV); 3) 24 h of HFOV plus surfactant therapy (S+HFOV); 4) 1 h of PLV followed by 23 h of CV (PLV); and 5) 24 h of CV without previous lung injury (control group). Piglets randomized to S+CV or S+HFOV received natural surfactant (100 mg/kg). PLV with FC-77 was started in an initial dose of 30 mL/kg over 30 min followed by 0.5 mL x kg(-1) x min(-1) for another 30 min. After 1 h of PLV the animals were conventionally ventilated for 23 h. Before acute lung injury and after 24 h the number of inflammatory cells and the levels of IL-6, leukotriene B4, and tumor necrosis factor-alpha were measured in the bronchoalveolar lavage fluid. Additionally, the oxygenation index and the histopathologic damage were evaluated. Before acute lung injury, the number of inflammatory cells and the levels of mediators in bronchoalveolar lavage fluid were not different among the groups. After 24 h, the number of granulocytes in the PLV group was as low as in the control group. leukotriene B4 and IL-6 levels were found to be elevated in all groups except the control group (p < 0.01). The release of leukotriene B4 and IL-6 was lowest in the PLV group when compared with S+HFOV, S+CV, or CV (p < 0.05). No differences among the groups were detected for tumor necrosis factor-alpha. Although the concentrations of leukotriene B4 and IL-6 after PLV were lowest in the PLV group, histopathologic evidence of damage and the oxygenation index in the PLV group did not differ from that found in the S+CV or S+HFOV groups. In conclusion, PLV with perfluorocarbons may protect the lung from acute pulmonary inflammation more effectively than CV or HFOV does.  相似文献

BACKGROUND: Partial liquid ventilation (PLV) with perfluorochemical (PFC) has been advocated as a new therapy for acute respiratory distress syndrome in both clinical and animal studies, meconium aspiration syndrome, and RDS. PFC is referred to as liquid PEEP because it gets distributed to the most gravity-dependent regions of the lung due to its density. High-frequency oscillation (HFO) has been shown to prevent both acute and chronic lung injury in the management of very low birth weight infants with RDS, with gentle ventilation approach. Specifically, HFO with aggressive and adequate lung volume recruitment has been shown to reduce the incidence of chronic lung disease in very low birth weight infants. We hypothesized that PLV along with HFO might be effective in ARDS in an adult rabbit model. OBJECTIVES: To examine the efficiency of low-dose PLV with with HFO on pulmonary gas exchange and lung compliance in a surfactant-depleted rabbit model. METHODS: After induction of severe lung injury by repeated saline lung lavage, 19 adult white Japanese rabbits were randomized into two groups that received PLV with HFO (n=9) or HFO gas ventilation (n=10). Physiological and blood gas data were compared between the two groups by analysis of variance. RESULTS: The HFO-PLV group showed improved total lung compliance with maintenance of significantly lower mean airway pressure as compared with the HFO-GAS group so as to keep SpO2>90%. CONCLUSIONS: The addition of a low dose of PFC with HFO was effective in achieving adequate oxygenation, with a reduction in further lung injury in neonates.  相似文献

PURPOSE: Several reports describe children with refractory transfusion-dependent Diamond-Blackfan anemia who responded to extremely large doses of methylprednisolone. Limitations in available data prompted further exploration of this treatment approach. PATIENTS AND METHODS: This prospective treatment protocol was designed to test the efficacy and toxicity of oral megadose methylprednisolone in children with Diamond-Blackfan anemia who had previously failed to respond to standard doses of prednisone and who were dependent on regular packed red blood cell transfusions. Patients were treated with oral methylprednisolone, starting at a dose of 100 mg/kg per day, tapering slowly to 5 mg/kg per day at the end of 4 weeks and to 2 mg/kg per day after 7 weeks of induction therapy. Therapy was continued for a total of 23 weeks. Efficacy was assessed by increase in peripheral blood reticulocytes and increase or stabilization in hemoglobin concentration, which was maintained during and after steroid tapering. RESULTS: Nine children with Diamond-Blackfan anemia were registered on the study, and all were evaluable. Disease in four of the children failed to respond to megadose methylprednisolone therapy. The other five patients demonstrated a partial or complete response during the initial 4 to 8 weeks of therapy, but all subsequently experienced relapse during the ensuing 2 months as the corticosteroid dose was tapered. All patients required resumption of transfusions, although one later remitted spontaneously. Toxicity of megadose methylprednisolone was modest. CONCLUSION: None of nine children with refractory Diamond-Blackfan anemia treated with oral megadose methylprednisolone exhibited a clinically significant response. Alternative therapeutic strategies are required.  相似文献

BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is an acquired disorder characterized by immune-mediated platelet destruction. The authors performed a prospective, randomized trial comparing intravenous immunoglobulin (IVIG) with high-dose intravenous methylprednisolone in the treatment of children with acute ITP. The primary aim of the study was to compare the rate of platelet increase produced by either intervention. A decision to treat was based on the clinical presentation and not an arbitrary platelet count. In general, enrolled patients exhibited extensive bruising and platelet counts less than 10 x 10 /L (10,000/microL). PATIENTS AND METHODS: Seventy-seven consecutive patients, for whom the attending hematologist determined acute treatment was warranted, were studied. Forty-two patients received IVIG (1 g/kg/dose x2) and 35 received methylprednisolone (30 mg/kg/dose x3). Patients who exhibited an increase in platelet count of more than 50,000/microL after the first IVIG dose or the second methylprednisolone dose did not receive the second IVIG dose or the third methylprednisolone dose, respectively. Patients' ages ranged from 6 months to 15 years. Platelet counts were evaluated at presentation, 24, 48, 72 hours, 1 week, and 2 to 4 weeks. RESULTS: Eighty percent of patients treated with IVIG and 60% of patients treated with methylprednisolone demonstrated an increase in platelet count of 50,000/microL or more within 48 hours. Both IVIG and methylprednisolone therapy increased platelet counts significantly above pretreatment values. In the methylprednisolone group, the mean baseline platelet count was 4,600/microL, which rose to 14,000/microL after 24 hours, 38,000/microL after 48 hours, and 65,000/microL after 72 hours. The IVIG group had a mean baseline platelet count of 4,200/microL, which rose to 32,000/microL after 24 hours, 69,000/microL after 48 hours, and 146,000/microL after 72 hours. When compared with methylprednisolone, IVIG therapy produced a greater rise in platelet counts at 24, 48, and 72 hours, with no difference at 1 week or later time points. No serious bleeding was noted in either treatment group. CONCLUSIONS: Both IVIG and methylprednisolone produce a significant early rise in platelet count that is somewhat greater with IVIG. However, the higher platelet counts produced by IVIG may not justify the additional cost and potential risks of this agent.  相似文献

The effects of pretreatment with methylprednisolone on the reaction to a toxin isolated from group B beta-hemolytic streptococci, type III, were studied in seven sheep instrumented for chronic measurements of pulmonary lymph flow and pulmonary artery and left atrial pressure. Each sheep was infused with toxin alone on one day and with methylprednisolone plus toxin on a different day in random order. The toxin alone caused a two-phase reaction. After the infusion of toxin, alone, in the initial phase, pulmonary artery pressure increased from 16 +/- 1 to 45 +/- 5 mm Hg and the rectal temperature rose from 39.5 +/- 0.14 to 40.8 +/- 0.18 degree C. During the second phase, the peripheral blood granulocyte count decreased to 10% of baseline values and the lung lymph protein clearance increased from 5.1 +/- 1.1 to 11.2 +/- 1.8 ml/h, suggesting increased pulmonary vascular permeability. Methylprednisolone pretreatment did not alter the initial phase of pulmonary hypertension or the febrile response but completely abolished the granulocytopenia and the increased pulmonary vascular permeability. These effects are unlikely to be related to inhibition of prostaglandin synthesis. Prevention of the lung vascular injury by methylprednisolone may be related to inhibition of granulocyte accumulation in the lung.  相似文献
