Monitoring for course and complications revealed that 55.4% of patients underwent renal imaging, 27.7% had brain imaging, 75.4% received electrocardiography (ECG) assessments, 35.4% had echocardiography, and 44.6% had documented ophthalmologic evaluations.</p><p><strong>Conclusion: </strong>This study provides the first epidemiological and demographic assessment of hypoparathyroidism in the UAE, highlighting both similarities and differences in frequency, revealing unique patient characteristics, treatment patterns, and monitoring practices. Compared to global trends, UAE patients demonstrated a higher calcium requirement and distinctive demographic patterns, including a younger mean age and a male predominance in idiopathic cases. Despite regular calcium and vitamin D monitoring, the study highlights suboptimal biochemical surveillance and complication screening, underscoring the need for improved adherence to clinical guidelines.</p>","PeriodicalId":17334,"journal":{"name":"Journal of the Endocrine Society","volume":"10 6","pages":"bvag077"},"PeriodicalIF":4.4,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13184618/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147982238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
