目的 探讨重组人干扰素α-2b雾化治疗联合人免疫球蛋白治疗新生儿合胞病毒性肺炎的临床疗效研究。方法 选取2018年2月-2021年2月在本院住院就诊的合胞病毒性肺炎新生儿120例,按照随机数字表法将患儿分为观察组和对照组,每组各60例。对照组使用重组人干扰素α-2b雾化治疗7d,观察组在治疗组的基础上联合给予静注用人免疫球蛋白持续治疗3d。观察两组患者的临床疗效、哮鸣音持续时间、咳嗽持续时间、喘憋持续时间、血清IgE和T淋巴细胞亚群CD3+水平和药物不良反应。结果 观察组的临床有效率为95.00%,对照组的临床有效率为90.00%,两组患者的临床有效率比较差异无统计学意义(P>0.05)。观察组的哮鸣音持续时间、咳嗽持续时间、喘憋持续时间比对照组明显更短,差异具有统计学意义(P<0.05)。治疗后,两组患者的血清IgE水平都降低,T淋巴细胞亚群CD3+水平升高,且观察组的幅度更大(P<0.05)。两组患者在住院期间都未发生严重的药物不良反应。结论 重组人干扰素α-2b雾化联合人免疫球蛋白治疗新生儿合胞病毒性肺炎没有显著提升临床疗效,但是可以明显缩短哮鸣音持续时间、咳嗽... 相似文献

Human respiratory syncytial virus (hRSV) is a major cause of respiratory disease and hospitalisation of infants, worldwide, and is also responsible for significant morbidity in adults and excess deaths in the elderly. There is no licensed hRSV vaccine or effective therapeutic agent. However, there are a growing number of hRSV vaccine candidates that have been developed targeting different populations at risk of hRSV infection. Animal models of hRSV play an important role in the preclinical testing of hRSV vaccine candidates and although many have shown efficacy in preclinical studies, few have progressed to clinical trials or they have had only limited success. This is, at least in part, due to the lack of animal models that fully recapitulate the pathogenesis of hRSV infection in humans. This review summarises the strengths and limitations of animal models of hRSV, which include those in which hRSV is used to infect non-human mammalian hosts, and those in which non-human pneumoviruses, such as bovine (b)RSV and pneumonia virus of mice (PVM) are studied in their natural host.Apart from chimpanzees, other non-human primates (NHP) are only semi-permissive for hRSV replication and experimental infection with large doses of virus result in little or no clinical signs of disease, and generally only mild pulmonary pathology. Other animal models such as cotton rats, mice, ferrets, guinea pigs, hamsters, chinchillas, and neonatal lambs are also only semi-permissive for hRSV. Nevertheless, mice and cotton rats have been of value in the development of monoclonal antibody prophylaxis for infants at high risk of severe hRSV infection and have provided insights into mechanisms of immunity to and pathogenesis of hRSV. However, the extent to which they predict hRSV vaccine efficacy and safety is unclear and several hRSV vaccine candidates that are completely protective in rodent models are poorly effective in chimpanzees and other NHP, such as African Green monkeys. Furthermore, interpretation of findings from many rodent and NHP models of vaccine-enhanced hRSV disease has been confounded by sensitisation to non-viral antigens present in the vaccine and challenge virus.Studies of non-human pneumoviruses in their native hosts are more likely to reflect the pathogenesis of natural hRSV infection, and experimental infection of calves with bRSV and of mice with PVM result in clinical disease and extensive pulmonary pathology. These animal models have not only been of value in studies on mechanisms of immunity to and the pathogenesis of pneumovirus infections but have also been used to evaluate hRSV vaccine concepts. Furthermore, the similarities between the epidemiology of bRSV in calves and hRSV in infants and the high level of genetic and antigenic similarity between bRSV and hRSV, make the calf model of bRSV infection a relevant model for preclinical evaluation of hRSV vaccine candidates which contain proteins that are conserved between hRSV and bRSV. 相似文献

Epidemiological research on respiratory syncytial virus (RSV) infections in children was carried out at the Virology Laboratory, University Teaching Hospital (UTH), in Lusaka, Zambia, from January-December 1996. Specimens including 736 nasal washings and 2424 throat swabs were collected from children with acute respiratory infections (ARI) and tested for RSV by enzyme immunoassay and by virus isolation. RSV was isolated in 62 (4.1%) of 1496 throat swabs collected from March to September and was detected in 99 (16.3%) of 609 nasal washings from March to November. The average RSV isolation rate was 2.6% and the average RSV detection rate was 13.5%. The highest RSV isolation (8.1%) and detection (30.5%) rates were in June 1996. RSV antibody in the 278 serum specimens collected from Zambian children, who were hospitalized in the paediatric ward, UTH, was detected using a standard neutralization test. The antibody positive rate was 60-80% in children > 4 years. It is evident that RSV is one of the main causal agents of ARI in children in Zambia. 相似文献

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory illness in children. Prevention of this infection is available with the use of intravenous immunoglobulin or an intramuscular humanized monoclonal antibody (palivizumab). Palivizumab has been available in Puerto Rico since 1999. The objective of this study was to follow-up infants who received RSV prophylaxis with palivizumab in Puerto Rico to assess its efficacy and safety. A total of 230 infants who received RSV prophylaxis during the 2000-2001 and 2001-2002 seasons were followed-up. Adverse events from injections were minimal including erythema (2%), fever (5%), pain (4%), and rash (2%). In none of the patients prophylaxis was discontinued due to side effects. Forty-four infants (19%) had at least one respiratory hospitalization throughout the season, with RSV confirmed in seven (3%). Most hospitalizations occurred in the month of August when infants had received only one dose of palivizumab and on December, a peak month for RSV infections. Five infants (2.2%) required admission to an intensive care unit. In none of them, RSV was confirmed. This study confirms that monthly intramuscular administration of palivizumab is effective in preventing serious RSV infections in high risk infants. 相似文献

In order to have information on the molecular epidemiology and genetic circulation pattern of human respiratory syncytial virus (HRSV) in Iran, we studied the genetic variability of both group A and B HRSV strains during seven consecutive years by sequencing the hypervariable C-terminal domain of G protein. A total of 485 children <2 years of age who were negative for influenza viruses, screened for the presence of HRSV in this research. HRSV was detected in 94 (19.38%) of the samples using nested RT-PCR. Group A viruses were isolated during each year, while group B viruses were isolated during 2009 and 2013. Phylogenetic analysis showed that all HRSV group A viruses belonged to three genotypes: GA1, GA2, GA5 and the group B viruses were in BA genotype. 相似文献
