BACKGROUND: Severe injury is associated with changes in monocytes that may contribute to poor outcomes. Longitudinal characterization of monocyte response patterns after trauma may provide added insight into these immunological alterations. METHODS: Venous blood obtained seven times during post-injury days 1 through 13 from 61 patients with an injury severity score >20 was assessed by flow cytometry for monocytes (CD14+) expressing HLA-DR or CD71 (transferrin receptor) and for circulating levels of interleukin (IL) 1alpha, IL-1beta, IL-6, soluble CD14 (sCD14), tumor necrosis factor-alpha (TNF-alpha), prostaglandin E(2) (PGE(2)), thromboxane B(2) (TXB(2)), and endotoxin. Urine neopterin was measured by high-pressure liquid chromatography, expressed as a neopterin-creatinine ratio. RESULTS: Trauma patients had leucocytosis days 1 through 13, monocytosis days 5 through 13, reduced proportions of CD14+HLA-DR+ cells days 2 through 5, and elevated proportions of CD14+CD71+ cells days 1 through 13. Neopterin was elevated all days, peaking on day 10. sCD14 was elevated days 2 through 13, and there were sporadic elevations of IL-1alpha, IL-1beta, IL-6, TNF-alpha, PGE(2), TXB(2), and endotoxin. Sepsis syndrome patients (n = 6) had larger and more prolonged reductions in CD14+HLA-DR+ cells and higher neopterin values, in comparison with uneventful patient outcomes. CONCLUSIONS: Altered proportions of monocytes expressing HLA-DR and CD71 and elevated sCD14 and urine neopterin levels, for up to 2 weeks after severe injury, underscores an extended period of profound immunological effects. Additional studies to more fully assess temporal monocyte response patterns after severe injury, including activation, may be warranted. 相似文献

OBJECTIVE: WHO's new Global Plan to Stop TB 2006-2015 advises countries with a high burden of tuberculosis (TB) to expand case-finding in the private sector as well as services for patients with HIV and multidrug-resistant TB (MDR-TB). The objective of this study was to evaluate these strategies in Thailand using data from the Thailand TB Active Surveillance Network, a demonstration project begun in 2004. METHODS: In October 2004, we began contacting public and private health-care facilities monthly to record data about people diagnosed with TB, assist with patient care, provide HIV counselling and testing, and obtain sputum samples for culture and susceptibility testing. The catchment area included 3.6 million people in four provinces. We compared results from October 2004-September 2005 (referred to as 2005) to baseline data from October 2002-September 2003 (referred to as 2003). FINDINGS: In 2005, we ascertained 5841 TB cases (164/100 000), including 2320 new smear-positive cases (65/100 000). Compared with routine passive surveillance in 2003, active surveillance increased reporting of all TB cases by 19% and of new smear-positive cases by 13%. Private facilities diagnosed 634 (11%) of all TB cases. In 2005, 1392 (24%) cases were known to be HIV positive. The proportion of cases with an unknown HIV status decreased from 66% (3226/4904) in 2003 to 23% (1329/5841) in 2005 (P< 0.01). Of 4656 pulmonary cases, mycobacterial culture was performed in 3024 (65%) and MDR-TB diagnosed in 60 (1%). CONCLUSION: In Thailand, piloting the new WHO strategy increased case-finding and collaboration with the private sector, and improved HIV services for TB patients and the diagnosis of MDR-TB. Further analysis of treatment outcomes and costs is needed to assess this programme's impact and cost effectiveness. 相似文献

Safety and immunogenicity of an HIV subtype B and E prime-boost vaccine combination in HIV-negative Thai adults 总被引:3,自引:0,他引:3
Nitayaphan S Pitisuttithum P Karnasuta C Eamsila C de Souza M Morgan P Polonis V Benenson M VanCott T Ratto-Kim S Kim J Thapinta D Garner R Bussaratid V Singharaj P el-Habib R Gurunathan S Heyward W Birx D McNeil J Brown AE;Thai AIDS Vaccine Evaluation Group 《The Journal of infectious diseases》2004,190(4):702-706
ALVAC-HIV (vCP1521) and AIDSVAX B/E were evaluated in a phase 1/2 trial of human immunodeficiency virus (HIV)-negative Thai adults. Of 133 volunteers enrolled, 122 completed the trial. There were no serious vaccine-related adverse events, nor were there intercurrent HIV infections. Lymphoproliferative responses to glycoprotein 120 E were induced in 63% of the volunteers, and HIV-specific CD8 cytotoxic T lymphocyte responses were induced in 24%. Antibody responses increased in frequency and magnitude in association with the dose level of AIDSVAX B/E. Binding and neutralizing antibodies to the MN strain were induced in 100% and 98%, respectively, of the volunteers receiving 600 microg of AIDSVAX B/E, and such antibodies to E strains were induced in 96% and 71%, respectively, of these volunteers. This vaccine combination was well tolerated and was immunogenic, meeting milestones for advancement to phase 3 evaluation. 相似文献

云南西盟佤族居民患疟求医的现状、费用支付能力和障碍 总被引:5,自引:0,他引:5
目的 评价佤族患疟求医的现状、费用支付能力和障碍。 方法 对社区居民进行问卷调查和参与式行动评估 ,对关键人员进行半结构深度访谈。 结果 自己治疗是村民治疗疟疾的第一行动 ,只有自己治疗无效后才到卫生机构求医 ;5 1% (95 %CI :2 6~ 8 9% )问卷调查回答者从不求医 ,8 8% (95 %CI :5 4~ 13 3 % )仅靠自己治疗 ;3 7 4% (95 % :3 0 9~ 44 3 % )付不起疟疾治疗费 ;村民提出的疟疾治疗费为平均RHB 64 15± 7 0 6(范围 :0~ 5 0 0 )元 ,88 5 % (95 %CI :82 4~ 93 0 % )的人认为不能超过RHBl0 0元。 结论 佤族中的患疟求医行为不当 ,障碍为经济 ,地理 ,知识和技术上的不可及性 ;疟疾病例的家庭管理是改善疟疾治疗现状的方法之一。 相似文献
