ABSTRACT: Measurement of intima-media thickness (IMT) of carotid artery by ultrasound, is well known method. Using this noninvasive method in various risck factors such as diabetes mellitus, dislipidemia, hypertension, smoking, age, obesity could be very usefull in pathophisiology studies of atherosklerosis.
The aim of this study was to measure intima media thickness (IMT) of carotid artery, as an early indicator for development of atherosclerosis, and too estemate if there is any significant differences between investigated groups of pts (diabetics pts, pts with glucose intolerance and obese pts without diabetes an older than 45 years).
110 pts were devided in five groups: three groups of diabetics pts: type 1 DM (25) pts, type 2 (25) pts and type 2 DM de novo (20), and (20) pts with glucose intolerance, and 20 pts obese without diabetes, older than 45 years of age. Correlation of metabolic parameters (body mass index (BMI), hip circumference (OS), lipid status) with IMT was performed as well as hipertension, age, sex, smoking and alcohol abuse.
The authors used 2 test and Spearman's correlation.
Intima media ticknes (IMT) was highly statisticly significant in groups of DM type 2 and DM tipe 2 de novo. IMT was stat. sig. in pts with high values of BMI and hip circumference according to those pts with normal values. It was also stat. sig. in pts with smoking hiperlipoproteinemia and hipertension. There was no stat. sig. correlation of IMT with sex, age and alcohol abuse.
This study showed that diabetics pts have frequent patological changes on arteri vessels and these changes are difuse and frequently with complicated wall leasens. The influence of these risck factors is very important because their sinergetic effects may augment clinical manifestation of atherosclerosis.

ABSTRACT: The aim of this study was measurement of artery intima media thickness (IMT) and plaques as an early indicator of atherosclerosis in diabetics comparing with other risk factors of carotid artery.
110 pts: 50 with Diabetes Mellitus, type 1 (25) and type 2 (25), 20 pts with glucose intolerance, 20 pts with type 2 de novo and 20 pts obese without diabetes. Ultrasound examination (using 7.5 MHz sound on Toshiba SSA-270A) end measurement of intima-media ticknes (IMT) were performed on Carotis communis (CCA), bifurcation and distal from bifurcation to a.carotis intern (ACI), expressed in mm. Plaques were correlated with other common factors age, BP, lipid parameters (Chol, HDL, LDL, Triglycerides), smoks, alcoholism and obese (BMI). The authors used 2 test and Spearman's correlation.
The lowest percent of plaques was found in group with type DM 1. The highest percent of plaques was found in type DM 2. Statistically there is highly significant difference between plaques founded on type 2 DM and types 2 DM de novo and on other types.
DM is not an independent risk factor for developing of macroangiopathic changes an arterial walls, but their appirience are more presenting in diabetic patients. The highest number of plaques are presenting DM type 2 (29.6%), and after type 2 de novo (26.8%), the next highest position of plaques were in patients with obese but without DM and intolerantio glucosae (IFG+IGT) (17.1%) and type 1 DM (9.8%). Risk factors were presented in following percentage: Obese 80.5% pts; hyperlipidema 53.7% pts; HTA 51.3%; smoking 51.2% pts and alchocholism 2.4% pts. According to these results, all risk factors were included in patophysiology of plack forming except alcoholism. Influences of these risk faktors are very importance and their synergic action lids to their rapid appirience and clinical manifestations. DM has specific position in patophisiology of atherosclerosis.

ABSTRACT: AIM: To evaluate the correlation between metabolic control and the presence and severity level of diabetic retinopathy (DR)
in patients with diabetes type 2. METHODS: This cross-sectional study included 80 patients divided into four groups according
to the duration of the disease: de novo; up to 10 years; from 11 to 20 years; and over 20 years. In order to evaluate the metabolic control each patient was tested
for: glycosylated hemoglobin (HbA1c), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglycerides
(TG). According to eye fundus changes patients were classified following the American Academy of Ophthalmology classification.
RESULTS: The patients with DR had significantly increased values of HbA1c. (9.5 ± 1.83%) and decreased values of HDL-C (1.1 ± 0.21 mmol/L) compared to patients without DR (6.9 ± 1.29%, t = 5.088;
p < 0,001) and (1.3 ± 0.25 mmol/L, t = 3.022; p < 0.01) respectively. The presence and severity level of DR correlated positively
with HbA1c values (p < 0.001) and poor glycaemic control (p < 0.001) while HDL-C values correlated inversely with the presence (p <
0.01) and severity level of DR (p < 0.05). CONCLUSION: Poor metabolic control determined by the increased values of HbA1c and decreased values of HDL-C correlates with the presence and severity of DR.
ZIELSETZUNG: Die Bewertung der Korrelation zwischen Wechselstoffkontrolle und Präsenz und Schweregrad der diabetischen Retinopathie
(DR) bei Patienten mit Typ-2-Diabetes. METHODEN: Diese Querschnittstudie umfasste 80 Patienten, die in vier Gruppen eingeordnet
wurden, nach der Dauer der Krankheit: de novo; bis zu 10 Jahren; 11 bis 20 Jahre; und über 20 Jahre. Um die Stoffwechselkontrolle zu bewerten wurden bei jedem Patient
die folgenden Parameter getestet: glycosiliertes Hämoglobin (HbA1c), Gesamtcholesterinspiegel (TC), High-Density Lipoprotein Cholesterin (HDL-C), Low-Density Lipoprotein Cholesterin (LDL-C)
und Triglyceride (TG). Abhängig von der Änderung an der Netzhaut wurden die Patienten nach der Klassifizierung der Amerikanischen
Akademie für Augenheilkunde eingeordnet. ERGEBNISSE: Patienten mit DR hatten deutlich erhöhte HbA1c-Werte (9,5 ± 1,83%) und verringerte HDL-C-Werte (1,1 ± 0,21 mmol/L) im Vergleich zu Patienten ohne DR (6,9 ± 1,29%, t = 5,088;
p < 0,001 und 1,3 ± 0,25 mmol/L, t = 3,022; p < 0,01). Die Präsenz und der Schweregrad der DR standen in positiver Wechselwirkung
mit HbA1c-Werten (p < 0,001) und schlechter glykämischer Kontrolle (p < 0,001), während sich HDL-C Werte umgekehrt proportional zur
Präsenz (p < 0,01) und zum Schweregrad der DR (p < 0,05) verhielten. SCHLUSSFOLGERUNG: Schlechte Stoffwechselkontrolle, gemessen
anhand erhöhter HbA1c-Werte und verringerter HDL-C-Werte, steht in Wechselwirkung mit der Präsenz und dem Schweregrad der DR.
