No standardized guidelines currently exist to guide pregnancy management, as CVID is a rare diagnosis, with pregnancy outcomes limited to case reports and case series. Establishing a structured approach to care is important to optimize maternal and fetal outcomes. Methods: A narrative review of the literature with a structured search was performed to detail pregnancy outcomes in CVID and management strategies. A 10-year retrospective chart review of women with CVID who became pregnant while receiving care at the McGill University Health Centre between January 2015 and January 2025 was conducted to add to the existing clinical data. Results: Pregnancy outcomes were improved through pre-conception planning, regular serum Immunoglobulin G (IgG) monitoring, trimester-based immunoglobulin replacement dose adjustments, proactive management of autoimmune or infectious complications, and multidisciplinary care. Subcutaneous immunoglobulin may offer better flexibility and stability of IgG levels. Conclusions: In the available observational literature and our institutional experience, many patients with CVID have carried pregnancies to term with favorable maternal and neonatal outcomes when managed with IgRT and multidisciplinary coordination. We outline a stepwise multidisciplinary framework for clinicians caring for women with CVID who are planning or undergoing pregnancy, and we identify gaps in knowledge for future studies.<\/jats:p>","DOI":"10.3390\/jcm15103810","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T14:19:29Z","timestamp":1778854769000},"page":"3810","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Common Variable Immune Deficiency and Pregnancy: Improving Outcomes Through Multidisciplinary Care"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9713-4562","authenticated-orcid":false,"given":"Fatemah","family":"Alyaqout","sequence":"first","affiliation":[{"name":"Division of Clinical Immunology and Allergy, McGill University Health Centre, 1650 Cedar Ave, Montreal, QC H3G 1A4, Canada"},{"name":"Division of Clinical Immunology and Allergy, Sheikh Jaber Al Ahmad Al Sabah Hospital, Ministry of Health Kuwait, Khalid Ben Abdul-Aziz Street, Kuwait 13018, Kuwait"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Aw","sequence":"additional","affiliation":[{"name":"Division of Internal Medicine, Department of Medicine, McGill University Health Centre, 1001 Bd D\u00e9carie, Montreal, QC H4A 3J1, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eisa","family":"Saleh","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Allergy, McGill University Health Centre, 1650 Cedar Ave, Montreal, QC H3G 1A4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Derek","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, McGill University Health Centre, 1001 Bd D\u00e9carie, Montreal, QC H4A 3J1, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vanessa","family":"Polito","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Allergy, McGill University Health Centre, 1650 Cedar Ave, Montreal, QC H3G 1A4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Fein","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Allergy, McGill University Health Centre, 1650 Cedar Ave, Montreal, QC H3G 1A4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christos","family":"Tsoukas","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Allergy, McGill University Health Centre, 1650 Cedar Ave, Montreal, QC H3G 1A4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reza","family":"Alizadehfar","sequence":"additional","affiliation":[{"name":"Division of Allergy Immunology and Dermatology, Montreal Children\u2019s Hospital, McGill University Health Centre, 1001 Bd D\u00e9carie, Montreal, QC H4A 3J1, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Genevieve","family":"Genest","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Allergy, McGill University Health Centre, 1650 Cedar Ave, Montreal, QC H3G 1A4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1016\/j.iac.2022.07.009","article-title":"Primary Antibody Immunodeficiency and the Pregnant Patient","volume":"43","author":"Zhang","year":"2023","journal-title":"Immunol.
