Vital status was ascertained and cause of death was recorded.<\/jats:p>\n               <jats:p>RESULTS\u2014A total of 27 of 135 patients (20%) died during the follow-up period. Patients with MA (10 of 30, 33.3%) or proteinuria (5 of 6, 83.3%) at initial examination were more likely to die during follow-up than patients who had normal albumin excretion at baseline (12 of 99, 12%; \u03c72 for trend 21.9, P &amp;lt; 0.0001). The presence of abnormal albumin excretion and low BMI were independent risk factors of premature death. The causes of death were similar in patients with normal and abnormal urine albumin excretion. A total of 24.4% of initially normoalbuminuric survivors developed MA, and persistent proteinuria developed in 3.5%. Progressors had significantly higher albumin excretion rate at baseline compared with those who remained normoalbuminuric: 9.0 \u03bcg\/min (3.8\u201318) vs. 4.0 \u03bcg\/min (0.4\u201317.5); P &amp;lt; 0.001. A total of 21% of patients with MA at baseline reverted to normoalbuminuria, and persistent proteinuria developed in 32%. The likelihood of progression to persistent proteinuria was significantly greater in those with baseline MA compared with those with normal albumin excretion (P &amp;lt; 0.001).<\/jats:p>\n               <jats:p>CONCLUSIONS\u2014Even in long-standing type 1 diabetes of &amp;gt;30 years\u2019 duration, MA and proteinuria predict all-cause mortality. MA is a good predictor of persistent proteinuria.<\/jats:p>","DOI":"10.2337\/diacare.26.7.2144","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T22:51:27Z","timestamp":1173135087000},"page":"2144-2149","update-policy":"https:\/\/doi.org\/10.2337\/ada-journal-policies","source":"Crossref","is-referenced-by-count":30,"title":["Significance of Microalbuminuria in Long-Duration Type 1 Diabetes"],"prefix":"10.2337","volume":"26","author":[{"given":"Chankramath S.","family":"Arun","sequence":"first","affiliation":[{"name":"From the Department of Medicine, The Medical School, University of Newcastle, Newcastle Upon Tyne, U.K"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Stoddart","sequence":"additional","affiliation":[{"name":"From the Department of Medicine, The Medical School, University of Newcastle, Newcastle Upon Tyne, U.K"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Mackin","sequence":"additional","affiliation":[{"name":"From the Department of Medicine, The Medical School, University of Newcastle, Newcastle Upon Tyne, U.K"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean M.","family":"MacLeod","sequence":"additional","affiliation":[{"name":"From the Department of Medicine, The Medical School, University of Newcastle, Newcastle Upon Tyne, U.K"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John P.","family":"New","sequence":"additional","affiliation":[{"name":"From the Department of Medicine, The Medical School, University of Newcastle, Newcastle Upon Tyne, U.K"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sally M.","family":"Marshall","sequence":"additional","affiliation":[{"name":"From the Department of Medicine, The Medical School, University of Newcastle, Newcastle Upon Tyne, U.K"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1167","reference":[{"key":"2022031217285820600_R1","doi-asserted-by":"crossref","unstructured":"Anderson AR, Sandahl CJ, Andersen JK, Kreiner S, Deckert T: Diabetic nephropathy in type 1 (insulin-dependent) diabetes: an epidemiological study.
