Background Structural congenital heart defects (CHD) take a huge toll of congenital defects in children in India. Limited information is available regarding modifiable risk factors for its causation. This study was planned with an aim to determine the prevalence of congenital rubella infection in Indian infants with structural CHD’s. Methodology This cross-sectional, observational study was conducted at a tertiary care hospital in Northern India over 1 year period (1 July 2016 to 30 June 2017). Infants <6 months with structural CHD were enrolled after taking informed consent from their mothers. Blood samples were collected from mother–child binomials and tested for rubella IgM and IgG antibodies. Results A total of 80 infants (M : F = 56 : 24), having mean age 69.4 (±56.5) days; were enrolled. In these infants, prevalence of congenital rubella infection (either infant’s IgM rubella positive or infant’s IgG rubella titers higher than mother’s) was 8.75% (7/80). A total of 12.5% of studied mothers were seronegative for rubella IgG antibodies. Statistically significant association was found between the occurrence of congenital rubella and cataract (p = 0.0039), splenomegaly (p = 0.007) and microcephaly (p = 0.0084) in infants having structural CHD. Conclusions Congenital rubella syndrome still remains an important modifiable cause for structural CHD in India. Sincere efforts for rubella elimination via further strengthening current vaccination strategy would help in decreasing burden of structural CHD in India.

先天性风疹:婴儿先天性心脏缺陷的一个重要原因

背景结构性先天性心脏缺陷 (CHD) 在印度儿童中造成巨大的先天性缺陷。关于其原因的可修改风险因素的信息有限。本研究旨在确定印度结构性冠心病婴儿先天性风疹感染的患病率。方法学 这项横断面观察性研究在印度北部的一家三级医院进行,为期 1 年(2016 年 7 月 1 日至 2017 年 6 月 30 日)。在获得母亲的知情同意后,招募了患有结构性 CHD 的<6 个月的婴儿。从母子二项式采集血样,并检测风疹 IgM 和 IgG 抗体。结果共80名婴儿(男:女=56:24),平均年龄69.4(±56.5)天;被录取了。在这些婴儿中,先天性风疹感染(婴儿 IgM 风疹阳性或婴儿 IgG 风疹滴度高于母亲)的患病率为 8.75% (7/80)。共有 12.5% 的研究母亲对风疹 IgG 抗体呈血清反应阴性。在先天性风疹和白内障 (p = 0.0039)、脾肿大 (p = 0.007) 和小头畸形 (p = 0.0084) 之间发现结构性先天性心脏病婴儿的发生率具有统计学意义。结论 先天性风疹综合征仍然是印度结构性冠心病的一个重要的可改变原因。通过进一步加强当前的疫苗接种策略来消除风疹的真诚努力将有助于减轻印度结构性冠心病的负担。5% 的研究母亲风疹 IgG 抗体呈血清阴性。在先天性风疹和白内障 (p = 0.0039)、脾肿大 (p = 0.007) 和小头畸形 (p = 0.0084) 之间发现结构性先天性心脏病婴儿的发生率具有统计学意义。结论 先天性风疹综合征仍然是印度结构性冠心病的一个重要的可改变原因。通过进一步加强当前的疫苗接种策略来消除风疹的真诚努力将有助于减轻印度结构性冠心病的负担。5% 的研究母亲风疹 IgG 抗体呈血清阴性。在先天性风疹和白内障 (p = 0.0039)、脾肿大 (p = 0.007) 和小头畸形 (p = 0.0084) 之间发现结构性先天性心脏病婴儿的发生率具有统计学意义。结论 先天性风疹综合征仍然是印度结构性冠心病的一个重要的可改变原因。通过进一步加强当前的疫苗接种策略来消除风疹的真诚努力将有助于减轻印度结构性冠心病的负担。结论 先天性风疹综合征仍然是印度结构性冠心病的一个重要的可改变原因。通过进一步加强当前的疫苗接种策略来消除风疹的真诚努力将有助于减轻印度结构性冠心病的负担。结论 先天性风疹综合征仍然是印度结构性冠心病的一个重要的可改变原因。通过进一步加强当前的疫苗接种策略来消除风疹的真诚努力将有助于减轻印度结构性冠心病的负担。
