The BCG vaccination is considered safe for a competent immune system. However, in children with weakened immune systems cause of which can be primary or secondary, the vaccine may lead to side effects which can be localized or disseminated. In this study, we report a spectrum of inborn errors of immunity (IEI) commonly referred to as primary immunodeficiency disorders (PIDs) diagnosed in a large cohort of patients presenting with complications to BCG vaccination from India. Retrospective data analysis of patients referred to ICMR\u2010 National Institute of Immunohematology (ICMR\u2010NIIH) for IEI workup between 2007 and 2019 was done. IEI was identified in n\u00a0=\u00a052\/90 (57.7%) patients presenting with BCG complications. Of these, n\u00a0=\u00a013(14.4%) patients were diagnosed with severe combined immune deficiency, n\u00a0=\u00a015(16.7%) with chronic granulomatous disease, n\u00a0=\u00a019(21.1%) with Inborn errors of IFN\u2010\u03b3 immunity, n\u00a0=\u00a04(4.4%) with Combined immunodeficiency and n\u00a0=\u00a01(1.1%) with Leucocyte Adhesion Deficiency type1. Majority of cases with BCGosis (88%) had an underlying IEI. This study strongly highlights the need for evaluation of patients with BCG complications for underlying IEI. While disseminated BCGosis strongly predicts underlying IEI, even localized persistent adenitis may be a warning sign of underlying IEI. It is also strongly recommended to record a family history of previous sibling death prior to administration of this live vaccine and deferring live vaccine till the diagnosis of IEI is ruled out in cases with a positive family history.<\/jats:p>","DOI":"10.1111\/sji.13010","type":"journal-article","created":{"date-parts":[[2020,12,16]],"date-time":"2020-12-16T19:20:59Z","timestamp":1608146459000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Spectrum of Inborn errors of immunity in a cohort of 90 patients presenting with complications to BCG vaccination in India"],"prefix":"10.1111","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5030-0437","authenticated-orcid":false,"given":"Reetika Malik","family":"Yadav","sequence":"first","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aparna","family":"Dalvi","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maya","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Umair Ahmed","family":"Bargir","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6407-5082","authenticated-orcid":false,"given":"Snehal","family":"Shabrish","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0350-1439","authenticated-orcid":false,"given":"Jahnavi","family":"Aluri","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manasi","family":"Kulkarni","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gouri","family":"Hule","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyanka","family":"Kambli","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyanka","family":"Setia","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neha","family":"Jodhawat","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prasad","family":"Taur","sequence":"additional","affiliation":[{"name":"Bai Jerbai Wadia Hospital for Children Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mukesh","family":"Desai","sequence":"additional","affiliation":[{"name":"Bai Jerbai Wadia Hospital for Children Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6380-3116","authenticated-orcid":false,"given":"Manisha Rajan","family":"Madkaikar","sequence":"additional","affiliation":[{"name":"Department of Paediatric Immunology and Leukocyte Biology National Institute of Immunohematology (ICMR) Mumbai India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,1,7]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1086\/499953"},{"key":"e_1_2_9_3_1","unstructured":"WHO Immunization Vaccines and Biologicals Department Quality Safety & Standards Global Vaccine Safety.Information sheet.
