Prolonged Untreated Disease and Limited English Proficiency: A Case of Van Wyk-Grumbach Syndrome.

Children from families with limited English proficiency have worse health outcomes than those from English-speaking families, likely related to the impact of a variety of social determinants on an increased risk of delayed presentation, diagnosis, and loss to follow-up. Van Wyk-Grumbach syndrome (VWGS) is a result of prolonged untreated primary hypothyroidism and early diagnosis of hypothyroidism is critical to prevent VWGS from developing. Whether social determinants of health, particularly limited English proficiency, impact the development, diagnosis, and treatment of VWGS has not been discussed previously. Here, we describe the case of an adolescent girl diagnosed with VWGS whose primary caregiver is foreign-born and with limited English proficiency, explore factors that may have placed her at increased risk for delayed presentation of VWGS, and discuss ongoing challenges of her disease management. We briefly review the pathophysiology of VWGS, emphasize the importance of being sensitive to this atypical presentation of hypothyroidism, and explore the intersections of this case with limited English proficiency status.
