Background/Aims:
End-stage renal disease (ESRD) is one of the most serious complications of type 1 diabetes, but scarcely studied. Our aim was to estimate the association between biochemical variables and survival among these patients.
Methods:
This was an incident cohort study of patients with type 1 diabetes entering chronic renal replacement therapy (RRT) in Finland 2000-2011 (n = 834). Biochemical variables were measured before the initiation of RRT. Adjusted relative risk of death according to biochemical variables was estimated by Cox regression.
Results:
When adjusted for age, sex, comorbidities, and initial treatment modality of RRT, the most important predictors of death were low creatinine and albumin and high C-reactive protein.
Conclusion:
Among type 1 diabetes patients entering chronic RRT, biochemical variables independently associated with survival are creatinine, albumin and C-reactive protein. They reflect the nutritional status, proteinuria, liver function, and ongoing inflammatory process. Treatment of these might improve survival.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
