Omphalitis is the infection of the umbilical cord stump, which can lead to septicaemia and significant neonatal morbidity and mortality. Very little data is available on the aetiology of neonatal omphalitis in India.
To identify the causative agents of omphalitis in neonates and determine the antimicrobial susceptibility patterns of the isolates.
A prospective study was conducted at ESI-PGIMSR and ESIC Medical College, Joka, a tertiary care teaching hospital in Eastern India for a period of four months (from 1st January 2016 to 30th April 2016). Neonates were screened for omphalitis on the basis of presence of pus and redness for inclusion. Clinical examination, Gram stain and culture of umbilical discharge, identification of organisms by biochemical tests and VITEK 2 Compact (bioMereiux Inc., France) was done. Antimicrobial susceptibility by Kirby Bauer disc diffusion method and E-strip agar diffusion method (for vancomycin and teicoplanin) were performed and interpreted according to the Clinical and Laboratory Standards Institute (CLSI) guidelines version 2015.
A total of 623 neonates were screened, among whom 21 (3.37%) were positive for our screening criteria for omphalitis. Cultures from the exudates of those cases yielded growth of in 19 (90.47%) samples, all of which were found to be methicillin resistant (MRSA). Resistance to erythromycin was seen among 36.82% isolates and inducible clindamycin resistance was seen among 31.57% isolates of .
MRSA can be the most common cause of omphalitis. However, this finding needs to be evaluated in larger prospective studies.
脐炎是脐带残端的感染,可导致败血症以及新生儿显著的发病率和死亡率。关于印度新生儿脐炎的病因,现有数据极少。
确定新生儿脐炎的病原体,并确定分离菌株的抗菌药物敏感性模式。
在印度东部一家三级护理教学医院——ESI-PGIMSR和ESIC医学院(乔卡)进行了一项为期四个月(从2016年1月1日至2016年4月30日)的前瞻性研究。根据是否存在脓液和发红情况对新生儿进行脐炎筛查以纳入研究。进行了临床检查、脐带分泌物的革兰氏染色和培养,通过生化试验和VITEK 2 Compact(法国生物梅里埃公司)鉴定细菌。采用 Kirby Bauer 纸片扩散法和E试纸条琼脂扩散法(用于万古霉素和替考拉宁)进行抗菌药物敏感性试验,并根据2015年版临床和实验室标准协会(CLSI)指南进行解读。
共筛查了623名新生儿,其中21名(3.37%)符合我们的脐炎筛查标准。这些病例的渗出物培养在19份(90.47%)样本中培养出细菌生长,所有样本均被发现为耐甲氧西林金黄色葡萄球菌(MRSA)。36.82%的分离菌株对红霉素耐药,31.57%的金黄色葡萄球菌分离菌株存在诱导性克林霉素耐药。
MRSA可能是脐炎最常见的病因。然而,这一发现需要在更大规模的前瞻性研究中进行评估。
