[Hyperosmolar hyperglycemic state].

The hyperglycemic hyperosmolar state (HHS) is a serious acute complication of diabetes decompensation, especially in type 2 diabetes (T2DM), and with critical prognosis. Primary characteristics of HHS include extreme hyperglycemia, severe dehydration (with prerenal hyperazotaemia), plasma hyperosmolarity, frequent disorders of consciousness, absent or minimum ketoacidosis (with higher values, only found in combined forms). Both DKA and HHS have a common pathogenetic mechanism, but both states are opposite extreme deviations, and the boundaries between them are not entirely clear.

[Long-term acting insulin analogues and the risks of hypoglycemic incidence].

As recommendation for treatment of type 2 diabetes mellitus, incorporating individualization of therapeutic targets for patients with co-morbidities, for whom hypoglycemia increases the risk of complications. The sufficient target value is 60 mmol/mol of HbA1c under the guidelines of Czech Diabetesl Society. Insulin therapy becomes essential for a whole line of patients, including those of advanced age, in relation to duration of diabetes and progression of the disease.

Transient ischemic dilation ratio (TID) correlates with HbA(1c) in patients with diabetes type 2 with proven myocardial ischemia according to exercise myocardial SPECT.

Objective: Abnormal values of the transient ischemic dilation ratio (TID) according to an exercise myocardial SPECT are linked to severe coronary artery disease. The authors investigated the relationship between TID and the levels of VCAM, ICAM, E-selectin, microalbuminuria, intima-media thickness and HbA(1c) of diabetic subjects.

Methods: We observed 38 subjects with diabetes type 2 (10 women, 28 men), of average age 56.
