The epidemiology and disease burden of congenital TORCH infections among hospitalized children in China: A national cross-sectional study.

BACKGROUND: Congenital TORCH (Toxoplasma gondii (T. gondii), rubella virus (RV), cytomegalovirus (CMV), and herpes simplex virus (HSV)) infections are associated with a variety of adverse prenatal and neonatal events, including miscarriage, malformations and developmental abnormalities, and they remain an issue that cannot be neglected in China. However, the current research focuses more on the general screening of TORCH in women of childbearing age, and the medical information of children hospitalized due to congenital and perinatal TORCH infections has not been described in detail. This study summarized and analyzed the epidemiological characteristics, clinical manifestations, length of stay (LOS), and the disease burden of hospitalized children diagnosed with congenital TORCH infections in 27 children's hospitals in China. METHODOLOGY: Based on the face sheet of discharge medical records (FSMRs) of hospitalized children in 27 tertiary children's hospitals collected in the Futang Research Center of Pediatric Development and aggregated into FUTang Update medical REcords (FUTURE), we summarized and analyzed the epidemiological characteristics, clinical manifestations, LOS, the disease burden (in US dollars, USD) and potential risk factors for hospitalized children diagnosed with congenital toxoplasmosis, congenital rubella syndrome, congenital cytomegalovirus infection, and congenital HSV in 27 children's hospitals in China from 2015 to 2020. RESULTS: One hundred seventy-three patients aged 0-<1 year were hospitalized for congenital TORCH infections. Among infections with TORCH, hospitalization with congenital toxoplasmosis was the least common, with only five cases were reported (2.89%), while the LOS was the highest. The proportion of patients with congenital rubella syndrome (CRS) was 15.61%, and 86% of children hospitalized with CRS had cardiovascular malformations, and the economic burden was the highest. Congenital CMV infection cases accounted for the largest proportion (76.30%). Overall, 5.20% of patients were infected with HSV, and the expense of hospitalization for congenital HSV infection was relatively low. CONCLUSION: In the present study, the hospitalization proportion due to congenital TORCH infection was extremely low (17.56 per 100,000 neonates), indicating that China's congenital TORCH infection prevention and control policies remain effective. The lowest proportion of patients was hospitalized with congenital toxoplasmosis, while the LOS was the longest. The economic burden of CRS was heavy, and infants are recommended be vaccinated against RV in a timely manner. Congenital CMV infections accounted for the largest proportion of patients, suggesting that the disease burden of congenital CMV infection cannot be ignored, and the prevention of congenital CMV infection during pregnancy is still an important issue that needs to pay attention. The expense of hospitalization for congenital HSV infection was relatively low, while the disease burden increases significantly when patients develop complications. These data illustrate the importance of improving screening for congenital TORCH infections in the early diagnosis and treatment of neonatal patients.

Targeting rubella for elimination.

Rubella is an acute, usually mild viral disease. However, when rubella infection occurs just before conception or during the first 8-10 weeks of gestation, it causes multiple fetal defects in up to 90% of cases, known as Congenital Rubella Syndrome (CRS). It may result in fetal wastage, stillbirths and sensorineural hearing deficit up to 20 weeks of gestation. Rubella vaccine (RA 27/3) is highly effective and has resulted in elimination of rubella and CRS from the western hemisphere and several European countries. Review of several studies documents the duration of protection over 10-21 years following one dose of RA27/3 vaccination, and persistent seropositivity in over 95% cases. Studies in India show seronegativity to rubella among adolescent girls to vary from 10% to 36%. Although due to early age of infection resulting in protection in the reproductive age group, incidence of rubella in India is not very high. However, due to severity of CRS coupled with introduction of RCV in private sector and in some of the states which is likely to lead to sub-optimal coverage and resulting higher risk of rubella during pregnancy in the coming decades, it is imperative to adopt the goal of rubella elimination. As in order to control measles, the country has adopted strategy of delivering second dose of measles through measles campaigns covering children 9 months to 10 years of age in 14 states, it is recommended to synergize efforts for elimination of rubella with these campaigns by replacing measles vaccine by MR or MMR vaccine. Other states which are to give second dose of measles through routine immunization will also have to adopt campaign mode in order to eliminate rubella from the country over 10-20 years. Subsequently, measles vaccine can be replaced by MR or MMR vaccine in the national schedule.

Laboratory assessment and diagnosis of congenital viral infections: Rubella, cytomegalovirus (CMV), varicella-zoster virus (VZV), herpes simplex virus (HSV), parvovirus B19 and human immunodeficiency virus (HIV).

Viral infections during pregnancy may cause fetal or neonatal damage. Clinical intervention, which is required for certain viral infections, relies on laboratory tests performed during pregnancy and at the neonatal stage. This review describes traditional and advanced laboratory approaches and testing methods used for assessment of the six most significant viral infections during pregnancy: rubella virus (RV), cytomegalovirus (CMV), varicella-zoster virus (VZV), herpes simplex virus (HSV), parvovirus B19 and human immunodeficiency virus (HIV). Interpretation of the laboratory tests results according to studies published in recent years is discussed.

Auditory brainstem response and otoacoustic emission assessment of hearing-impaired children of mothers who contracted rubella during pregnancy.

CONCLUSIONS: Based on the auditory brainstem response (ABR) results obtained in this study, the incidence of deafness in children whose mothers had rubella during pregnancy is high (29.5%), and deafness is profound in most cases (80%). Vaccinating women of childbearing age against rubella is essential to reduce the number of cases of childhood sensorineural hearing loss caused by gestational rubella. OBJECTIVE: It has been shown in the literature that, in Brazil, gestational rubella is responsible for approximately 21% of cases of deafness in children. The purpose of this study was to assess the incidence of deafness in children whose mothers had rubella during pregnancy. MATERIAL AND METHODS: Between February and July 2001, we conducted a prospective study assessing hearing status in 17 children (mean age 6 months). The mothers had serologically (ELISA) confirmed gestational rubella. We recorded ABRs and analysed distortion product otoacoustic emissions (DPOAEs). RESULTS: In 5 children (29.5%), ABRs revealed sensorineural hearing loss, which was moderate to severe in 1 (20%) and profound in 4 (80%). The hearing loss was bilateral in 3 children (60%) and asymmetrical in 4 (80%). Regarding DPOAEs, 7 children (41%) presented no response, and this occurred bilaterally in 4 (57%). All children with abnormal ABRs also presented abnormal DPOAEs. Two children with normal ABRs presented abnormal DPOAEs.

[35-year measles, mumps, rubella vaccination assessment in France]. / Evaluation de 35 années de vaccination rougeole-oreillons-rubéole en France.

AIM: The setting-up and the follow-up of a vaccination programme require important human and economical investments. Our study objective consists of the clinical benefit evaluation given by measles, mumps and rubella (MMR) vaccination since monovalent and combined vaccines availability (35 years for measles, 30 years for rubella and 20 years for mumps). METHOD: Vaccination impact has been evaluated from the modelisation for each disease under the shape of a decision tree relying on epidemiological data and on efficacy data of the vaccines. We have compared the results in terms of complications, sequaela, deaths in the vaccinated population (vaccination period) with the results that we would obtain if this same population had not been vaccinated (non vaccination period). The general model was applied to each of the three diseases excluding congenital rubella syndrome. They have been modelised according to the occurrence, or not, of a complication leading to an evolution towards either recovery or sequaela or death. The estimation of the number of avoided congenital rubella syndromes has been made from the number of protected women by vaccination and incidence figures of congenital rubella syndromes reported in the population considered before and after vaccination. RESULTS: In France over the period of time considered, almost 2 million meningitis, 60 000 encephalitis, 170 subacute sclerosis panencephalitis and more than 5600 neurological sequaela including more than 600 deafness cases have been avoided as a result of the MMR vaccination programme. Moreover, 590 000 pneumonia, more than one million of acute otitis media and 300 000 orchitis, 3000 rubella infection cases occurring during pregnancy have also been avoided. Overall, more than 12 000 deaths that have been avoided as a result of the MMR vaccination. CONCLUSIONS: In France, MMR vaccination programme leads to a huge benefit in terms of public health, which emphasises the true value of vaccination in the daily medical practice.

The logical case for "wrongful life".

Suits that claim that a child would be better off never having been born often founder on conceptual and logical dilemmas. However, the correct interpretation of "wrongful life" does not require a comparison between existence and nonexistence. The New Jersey Supreme Court's decision in the Procanik case to limit damages to extraordinary medical expenses, barring recovery for pain and suffering, is a reasonable resolution.

KIE: With the 1 Aug 1984 decision of its Supreme Court in Procanik v. Cillo, New Jersey joined California and Washington as the only states to have recognized the right of an infant with birth defects to collect damages in a wrongful life suit. Steinbock reviews the precedents for Procanik as well as cases where courts have shied away from awarding damages to infants because of an unwillingness to compare the relative merits of nonlife versus an impaired life. She argues that the correct interpretation of "wrongful life" does not require such a comparison. She also contends that the decision in the Procanik case to limit damages to extraordinary medical expenses, barring recovery for pain and suffering, is a just solution.

Benefits, risks and costs of immunization for measles, mumps and rubella.

For a single year, 1983, we compared the actual and estimated morbidity, mortality, and costs attributable to measles, mumps, and rubella with having or not having a childhood immunization program using the combined measles-mumps-rubella (MMR) vaccine. Without an immunization program, an estimated 3,325,000 cases of measles would occur as compared to 2,872 actual cases in 1983 with a program. Instead of an expected 1.5 million rubella cases annually, there were only 3,816 actual cases. Mumps cases were lowered from an expected 2.1 million to 32,850 actual cases. Comparable reductions in disease-associated complications, sequelae, and deaths are gained with an immunization program. Without a vaccination program, disease costs would have been almost $1.4 billion. Based on the actual incidence of disease in 1983, costs were estimated to be approximately +14.5 million. Expenditures for immunization, including vaccine administration costs and the costs associated with vaccine reactions, totaled $96 million. The resulting benefit-cost ratio for the MMR immunization program is approximately 14:1. The savings realized due to the use of combination rather than single antigen vaccine total nearly $60 million.

The multihandicapped child with congenital rubella: impact on family and community.

In 1967, a hospital-based education program was created to provide services to multihandicapped children with congenital rubella syndrome (CRS). Since then 214 children have been enrolled, including 126 (59%) with laboratory-documented congenital rubella infection. An assessment of the ongoing training and life needs of those children with CRS enrolled in the program and the concomitant impact on families and community facilities has documented the general failure of the children to progress toward independence in spite of extensive educational programs and support services. The human and economic costs of these severe rubella-caused disabilities already have been enormous and will continue to be so for many years because even in adulthood these victims will require 24-hr supervision and care. The extensive rubella-vaccination effort made since 1969 has resulted in a progressive decline in the percentage of children requiring enrollment in this program whose disabilities are due to congenital rubella. The last such enrollee was born in 1981.

The risk of birth defects: Jacobs v. Theimer and parents' right to know.

This Article discusses the Texas Supreme Court's holding in Jacobs v. Theimer that the parents of a defective child had a cause of action for damages against a physician for alleged negligent failure to inform the mother during pregnancy that she had contracted rubella and therefore might have a defective child, thereby causing her to lose the opportunity to have an abortion. The Article raises a number of questions that post-Jacobs courts probably will confront concerning the duty of physicians and genetic counselors to keep their clients informed; describes some social and medical developments--including recent progress in medical genetics and prenatal diagnosis--which are likely to make Jacobs a significant precedent; evaluates the court's decision to allow a damage suit only for the costs of treating and caring for the child's defects; and briefly addresses the question of whether the Jacobs case comes within the sphere of suits for what has come to be known as "wrongful birth" and "wrongful life."
