Respiratory syncytial virus and parainfluenza virus. The patient populations included in the study samples are shown in Table 3. Children with bronchopulmonary dysplasia [ 20 ].

Seasonality Another aspect that introduces complexity is the seasonality of RSV disease incidence, which varies annually. Regimen Source Total No. Conflicting evidence about the cost-effectiveness of palivizumab has led to changes in clinical recommendations on the use of RSV immunoprophylaxis and created confusion. Second, the cost of palivizumab prophylaxis is based on infant weight, which is determined partly by the gestational age at birth, as well as the chronologic age. For to , the RSV season onset ranged from mid-September to mid-November, season peak ranged from late December to mid-February, and season offset ranged from mid-April to mid-May in all 10 U. Under the optimized fixed start OFS regimen, the median improvement compared with the seasonal regimen across cities is 6.

Clin Vaccine Immunol ; YountUS [ 24 ]. Under the AAP regimen, Atlanta would see an increase of 2. Among the seasons considered, the OFS regimen would have conferred superior protection in ie, Trends and Surveillance Minus Related Pages.

MED30 Panozzo et al, 17 Decision tree focused on hospitalization using clinical trials and published data. The OFS strategy is detailed in Table 2. We determined the optimal timing of injections to maximize the duration of protection derived from maintaining palivizumab serum levels above an empirically determined threshold for immunologic protection. Studies suggest that among US children under the age of 5 years, RSV synagiss is responsible for anywhere from 57 to more than hospitalizations caliofrnia 2.

Assessment of RSV risk and severity in the United States in the absence of immunoprophylaxis use has not been available since before [ 7 ], and the epidemiology of RSV in high-risk infants indicated for palivizumab is influenced by the use of immunoprophylaxis. Consider certain socioeconomic or other high-risk patient subgroups explicitly. Keep your home smoke-free.

Economic analysis of palivizumab in infants with congenital heart disease.


Trends and Surveillance

Seaxon studies strengthening epidemiological data. Population pharmacokinetics of palivizumab, a humanized anti-respiratory syncytial virus monoclonal antibody, in adults and children. The fixed start dates used by the AAP-recommended and OFS regimens are more robust to high variability in early-season RSV activity than the seasonal regimen that uses surveillance-triggered start dates.

However, many practitioners initiate injections at the onset of RSV season as indicated by local surveillance.

By extending the window of protection to days, injections are initiated earlier in the OFS regimen, enabling early season protection without compromising late season protection. We found that most of the optimized start dates for OFS are earlier than November 1, with a median date of October 24 Figure 2 and Falifornia 2.

Critical revision of the manuscript for important intellectual content: Epidemiological and Clinical Data Challenges Participants at the round table agreed that an understanding of foundational epidemiology and outcomes associated with RSV disease is essential for better understanding the potential value of immunoprophylaxis and other prevention strategies across different risk groups. Florida has an earlier RSV season onset and longer duration than most regions of the country see figure.

World J Clin Pediatr.

Synagis is given as an injection, usually in the thigh muscle, each month during the RSV season. The virus can also live on surfaces for califrnia hours.

Potential conflicts of interest. Standardize terminology related to RSV disease. Serotyping, demographic data, and clinical data are not reported. Societal Perspective and Spillover Effects Californja 1 of the 7 studies [ 24 ] we reviewed included infant future productivity loss estimated over the expected lifetime of the recipient.

Economic impact of respiratory syncytial virus-related illness in the US: Synagsi were invited based on having one of the roles above, scientific interest in the area of RSV, and availability to attend an in-person meeting. For this study, we limited our search to articles that reported an original cost-effectiveness analysis study where the intervention was RSV prophylaxis with palivizumab; that studied either a US, Canadian, or UK population; and were published between January and December BentleyUK [ claifornia ].


Identifying which children should be targeted for RSV immunoprophylaxis remains a challenge for parents and health care providers of premature infants. Additionally, families and caregivers may suffer adverse health consequences based on increased illness severity or duration in the unprophylaxed infant. Direct costs included medical costs and medication costs, and indirect costs included missed work parent and mortality value. Economic Analysis Challenges and Limitations The limitations of epidemiology data on RSV disease hamper the ability to conduct a seqson economic analysis because of gaps in the underlying clinical data.

Participants were the approximately individuals who had specimens tested for RSV by National Respiratory and Enteric Virus Surveillance System laboratories in 18 US cities from July 1,through June 30, a total of tests.

Conflict of Interest Disclosures: Footnotes Conflict of Interest Disclosures: The 5-injection OFS regimen is expected to further reduce risk by a median of 6. The disease incidence is highest during specific times of year, which vary by region, with the special exceptions of Alaska, Hawaii, parts of Florida, and Texas.

Development of a humanized monoclonal antibody MEDI with potent in vitro and in vivo activity against respiratory syncytial virus. CDC is not responsible for Section compliance accessibility on other federal or private website. Although immunoprophylaxis does not prevent RSV infection, the severity of the symptoms is significantly reduced in those who are treated.

In addition, we describe the main highlights of a syangis table discussion with clinical, payer, research methods, and other experts about the available cost-effectiveness evidence for RSV immunoprophylaxis and the next steps for future research.
