The goal of our group is to gain deeper understanding
on the mechanisms behind renal and cerebrovascular complications in diabetes, with an emphasis on studying the relationships between these complications. The two primary initiatives are outlined below.

Hypoxia in diabetic kidney disease

Renal disease is a major driver of cardiovascular morbidity and mortality and contributes greatly to a poor quality of life in diabetes. Preventing renal hypoxia, an early risk factor for diabetic kidney disease, may play an important role in delaying the onset of this grave complication.

Via cutting edge methodology (renal haemodynamics, renal and cardiac imaging by BOLD MRI and PET-CT), we aim to detect early haemodynamic, metabolic, and morphological changes that lead to relative tissue hypoxia in the kidney. Our recent establishment of a renal lab within the FinnDiane which includes capabilities of measuring renal function (GFR; glomerular filtration rate, and ERPF; effective renal plasma flow), will enable us to perform these studies. Various interventions, such as maneuvers affecting cardiac autonomic neuropathy as well as pharmacological compounds, will be employed to reverse tissue hypoxia.

Risk factors for cerebrovascular disease in patients with type 1 diabetes

Diabetes and ischemic stroke are two major causes of early morbidity and mortality. We recently reported a high risk of premature death in individuals with type 1 diabetes, compared to type 2 diabetes and non-diabetic controls, in a large cohort of young individuals who had suffered a first ever stroke. The strongest risk factor for mortality was renal disease.

The goal of this collaborative longitudinal study is to find early markers and causal risk factors for cerebrovascular disease in individuals with type 1 diabetes. All subjects underwent detailed clinical examination, clinical and biochemical profiling, genetic (GWAS, whole genome sequencing) and retinal evaluations (fundus photos, OCTA), and brain MRI as part of the FinnDiane study. We aim to repeat these examinations in these individuals, to establish a longitudinal trajectory, and additionally include a cognitive examination to find structural-functional associations between brain anatomy and cognition.

The final aim of these two initiatives is to identify patients at risk for renal and cerebrovascular in order to plan their prevention and even find tools to improve their individual treatment to eventually delay or in best case halt these grim diseases.


Our group has developed a comprehensive collaborative network with high profile research groups nationally and internationally.
