The aims of this study were to determine the efficacy of sulphonylurea drugs during follow\u2010up, to explore the role of adjunctive therapies in this cohort and to describe micro\u2010 and macrovascular complications over longitudinal follow\u2010up.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Forty\u2010two individuals with an\n HNF4A<\/jats:italic>\n mutation were phenotyped in detail, including an oral glucose tolerance test to establish insulin secretory capacity. Subsequent markers, including oral hypoglycaemic usage, end\u2010organ complications, weight, cardiovascular co\u2010morbidity and biochemistry including HbA\n 1c<\/jats:sub>\n and urinary albumin, were recorded at clinical follow\u2010up.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Significant HbA\n 1c<\/jats:sub>\n reduction (\n p<\/jats:italic>\n \u2009=\u20090.045) was observed in 51.6% of people with an\n HNF4A<\/jats:italic>\n gene mutation on sulphonylurea monotherapy, and glycaemic control persisted after 6\u2009years (IQR: 3.5\u201311) of follow\u2010up. Adjunct agents including insulin are used in 48.4% of the cohort. These individuals have higher BMI (\n p<\/jats:italic>\n \u2009=\u20090.037), longer duration of diabetes (\n p<\/jats:italic>\n \u2009=\u20090.03) and reduced insulin secretory capacity (AUC C\u2010peptide\n p<\/jats:italic>\n \u2009=\u20090.01). Retinopathy was observed in 24.4%, nephropathy in 12.9% and coronary heart disease in 22.6% of the cohort.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Individuals with an\n HNF4A<\/jats:italic>\n mutation and normal BMI are likely to respond to sulphonylurea therapy. Avoidance of weight gain is associated with ongoing responsiveness to monotherapy. Adjunct therapies including GLP1RA and SGLT2i may play a role in further glycaemic management in addition to renal protective and cardioprotective effects.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/dme.70139","type":"journal-article","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T04:41:22Z","timestamp":1757997682000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Sulphonylurea efficacy and end\u2010organ outcomes in the management of\n HNF4A<\/scp>\n \u2010\n MODY<\/scp>"],"prefix":"10.1111","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7735-9711","authenticated-orcid":false,"given":"M.
