[Insulin resistance in type 2 diabetes patients]. / Insulinoopornosc u chorych na cukrzyce typu 2.

Among 1052 type 2 diabetics 11 patients with insulin requirement from 102 to 138 (average 123) i.u. were selected. They were only 1% of the population. Two of them (average age 49,5 years) suffered from diabetes 4 and 6 years, had BMI 26-27 kg/m2 and were free of other metabolic syndrome manifestations. Nine patients (8 women and one man) with average parameters--62 years-old, diabetes duration 15.7 years, BMI 34,7 kg/m2 suffered from metabolic syndrome and its complications such as ischemic heart disease and/or state after stroke. The attempt of treatment 7 patients with metformin (2550 mg/24h) for 3-4 months has not caused significant decrease of daily insulin requirement.

Enzymatic examination of potential interaction between statins or fibrates and consumed Tricholoma equestre.

The enzymatic investigations were done in 56 patients, including 30 females and 26 males in the age range 18-76 (mean 52 +/- 12). Thirty two of them (57.1%) suffered from type 2 diabetes. All the patients consumed voluntarily Tricholoma equestre; 43 of them only once from 70 to 150 g, and 13 patients from two to four times for 4 consecutive days (between 300 g and 1200 g). Twenty seven patients, because of hyperlipidemia, took statins (simvastatin á 20 mg--15 patients, lovastatin á 20 mg--6 patients, fluvastatin á 80 mg--3 patients, atorvastatin á 20 mg--3 patients) and seven took fibrates (4 patients-- enofibrate á 267 mg, and 3 patients--ciprofibrate á 100 mg). Two subjects ingested both simvastatin á 20 mg and fenofibrate á 267 mg. Three to six days after the last mushroom dish, blood samples were taken from patients to examine the serum creatine kinase (CK), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities. The biochemical analyses were performed by means of the kinetic spectrophotometry using the autoanalyzer Architect ClI8200 with Abbott proprietary reagents. Statistical analysis was performed by means of t-Student test. Tricholoma equestre taken by patients in a total amount from 70 g to 1200 g for four consecutive days did not cause the significant increase in serum CK, AST, ALT activities. Similar mushroom dishes consumed by patients constantly using statins or fibrates also did not increase significantly the serum CK, AST, ALT activities. Patients treated with statins or fibrates may eat Tricholoma equestre in reasonable amount according to the established tradition.
