“MONIKI” named after M.F. Vladimirsky D. Kulikov, MD, PhD Development of the method for evaluating the status of blood microcirculation system and the risk of microvascular complications development at diabetes mellitus based on optical spectroscopy

Conclusions Informative functional tests as well as an algorithm of the registration for the investigation of the blood skin microcirculation at diabetes were developed A method for processing and evaluating the results was also obtained.

Diabetes Mellitus It is time to SCREAM * *Data from Diabetes Atlas, 2013 International Diabetes Federation (IDF) 10,8 % global healthcare expenditure ! 5.1 million people died and 548 billion USD were spent due to diabetes in 2013 at half-percent of cases patients already have different complications at the time of diabetes diagnosis

Role of microcirculatory disorders in the pathogenesis of diabetes Insulin resistance Hyperglycemia Microcirculatory disorders Jorneskog et al., 2005 Clark, 2008 Fredriksson et al., 2010 Czernichow et al., 2010 Jarnert et al., 2012

Possible application points Early diagnostics of DM and it’s complications Control of sugar-lowering treatment efficiency

Examples of information processing

Inclusion/Exclusion criteria Age Body Mass Index Term of illness Micro/macrovascular complications in anamnesis Pernicious habits (alcohol, smoking) Arterial blood pressure level Status of carbohydrate metabolism (compensation/decompensation) Received treatment etc.

“MONIKI” named after M.F. Vladimirsky patients with DM in register “Mobile Diabetes Center” patients with early disruptions in carbohydrate metabolism Conducting research in context of a clinical survey Long-term case monitoring

Identifying signs for early diagnosis HyperglycemiaInsulin resistanceMicrocirculation disruptions DM 1 type +–+ DM 2 type +++ Prediabetes +/– High-risk group –+/– + symptomatic forms of DM (acromegaly, using of glucocorticoids, etc.)

Important Metrological aspects of the research Functional tests Forming studying and control groups
