BACKGROUND
The chronic complications of diabetes mellitus are important prognostic factors of diabetics. The pathogenic mechanisms have not been known exactly and the prevalence is different according to the race and the reporter. In general, the development of diabetic microangiopathy depends on the duration and the severity of disease, while that of macroangiopathy does not. This study was undertaken to investigate the prevalence of diabetic chronic complications according to age and duration of diabetes and to elucidate associated factors and correlation of chronic complications. METHODS: We studied 1,270 patients with non- insulin dependent diabetes mellitus (NIDDM) who visited the Endocrine-metabolism clinic at Kyungpook National University during the period from February 1992 to September 1996. We investigated prevalence, severity, associated factors and correlation of chronic vascular complications, including micro- and macroangiopathy. RESULT: 1) The ratio of male to female was similar and the average duration was 7.8 years. Diabetes mellitus was most prevalent in the 6th decade and the 1-5 years of diabetes duration. 2) The prevalences of retinopathy, nephropathy and peripheral polyneuropathy were 47.8%, 31.9% and 41.0%, respectively. Macrovascular complications were found in 6.2% of patients and the prevalences of coronary artery disease, cerebrovas-cular disease and peripheral artery disease were 2.4%, 3.4%, 0.4%, respectively. Prevalence of diabetic foot was 4.4%. 3) The prevalence and severity of microvascular complications increased as the age and diabetic duration of patients increased. In the group of same age, the prevalence of microvascular complications increased as the duration of diabetes increased. However, prevalence of macrovascular complica-tions especially coronary artery disease depended on the age, but not the duration of diabetes (p<0.05). 4) In the group over 10 years of diabetes, the fasting blood glucose, age and serum creatinine levels were increased, while hemoglobin and total protein levels were decreased than other groups (p<0.05). 5) The development of diabetic retinopathy was related to the duration, fasting blood glucose, albumine excretion rate and serum creatinine. The nephropathy was related to the duration and systolic blood pressure. The peripheral polyneuropathy was related to the duration, fasting blood glucose and body mass index. Macrovascular complications-particularly, coronary artery disease-were related to the age of diabeties (p<0.05). 6) There was significant relation between development of retinopathy, nephropathy and neuropathy but no relation between development of micro and macrovascular complications (p<0.05). CONCLUSION : The prevalence of microvascular complications in non-insulin dependent diabetics increased as the duration and the age of diabetics increased. The development of microvascular complications was related to the duration of disease and the glycemic control. There was relation between development of retinopathy, nephropathy and neuropathy. The development of macrovascular complications, however, was related to the age of diabetics but not to the microvascular complications. Our results suggest that different pathogenic mechanisms may be involved in the development of micro- and macrovaseular complications of diabetes mellitus.

BACKGROUND
Nonketotic hyperosmolar coma is usually a complication of non-insuli#n dependent diabetes and a syndrome of profound dehydration, hyperglycemia and hyperosmolarity. Therefore the patients present a progressive mental change. We evaluated the clinical manifestations of nonketotic hyperosmolar coma to assess the correlation between initial clinical manifestations and responses to treatment in patients with nonketotic hyperosmolar coma. METHODS: We studied 31 patients who had experienced proven nonketotic hyperosmolar coma at Kyungpook National University Hospital from March 1987 to February 1998. We divided nonketotic hyperosmolar coma patients into two groups, tbe complete recovery group and the incomplete recovery group, and compared clinical features and laboratory findings between these two groups. RESULTS: l) A total of 31 patients were studied. Eighteen patients were in the complete recovery group and thirteen patients were in the incomplete recovery group. 2) Mean age was 63.1+10.1 years old, initial blood glucose was 781.8+314.3 mg/dL, effective osmolarity was 342.6+34.9 mosm/L, arterial pH was 7.34. Serum creatinine level was 241.7+130.0 uol/L and BUN was 23.1+12.5 mmol/L. 3) Among clinical features of both groups (complete recovery and incomplete recovery groups), initial systolic blood pressure was 131.4+26.1 mmHg and 104.1+28.6 mmHg, diastolic blood pressure was 90.6+16.5 mmHg and 63.2+17.4 mmHg, and mean arterial blood pressure was 104.2 +18.2 mmHg and 76.8+19.7 mmHg. They revealed a significant difference statistically. 4) Arterial blood pH was 7.40 and 7.25, BUN was 18.4+11.7 mmol/L and 29.5+11.1mmol/L, and WBC count was 13850+4122/ mm and 19823+ 5946/mm. They revealed a significant difference statistically. 5) We also analyzed the significant factors together using multivariate logistic regression analysis. The only significant independent factor responsible for prognosis of nonketotic hyperosmolar coma was initial mean arterial blood pressure. CONCLUSION: Nonketotic hyperosmolar coma occurred more frequently in patients who were older and had abnormal renal function. The prognosis of patients was related with mean arterial blood pressure independently. Mean arterial blood pressure thought to be related to intravascular volume and arterial hypotension seems to reflect dehydration state. In conclusion, prevention and rapid correction of hypotension due to dehydration in older diabetics is the most important treatment to improve the prognosis.

BACKGROUND
The mechanism for accelerated atberosclerosis in diabetes mellitus is unclear although diabetes mellitus is associated with substantial increase in prevalence of atherosclerotic disease. Extracellular matrix formation by vascular smooth muscle cells has been accepted as playing important roles during development of atherosclerosis. High glucose condition has been reported to increase the synthesis of extracellular matrix such as collagen and fibronectin in cultured mesangial cells. Insulin and some cytokines such as TGF-B and PGF have also been reported to stimulate the synthesis of collagen in mesangial cells. So we studied the effect of high glucose, insulin, TGF-Band PDGF on vascular smooth muscle cells. METHODS: To determine the effect of bigh glucose condition on collagen synthesis in vascular smooth muscle cells, cells were grown in the culture medium containing either normal (5.5 mM) or high (25 mM) glucose. And we used several concentrations of TGF-B1PDGF-BB and insulin in order to determine the synergistic effects of collagen synthesis and type I collagen mRNA expression. RESULTS: We observed that cells cultured in high glucose media synthesized more collagen and increased expression of type I collagen mRNA as compared to normoglycemic media. The amount of synthesized collagen and type I collagen mRNA expression increased proportionally to the increase in insulin concentration. There was no relationship of TGF-B1or PDGF-BB with the expression of type I collagen mRNA but these cytokines stimulated the synthesis of collagen and noncollagen protein. There was no synergistic effect of col)agen synthesis and type 1collagen mRNA expression by high glucose, insulin, and cytokines. CONCLUSION: These results suggest that TGF-Band PDGF may not influence type I collagen mRNA expression under hyperglycemia or hyperinsulinemia in vascular smooth muscle cells. Further studies about the other types of collagen expressions such as type IV, and V are needed because TGF-Band PDGF stimulated the synthesis of collagen and noncollagen protein.

AbstractAbstract PDF
BACKGROUND
Diabetic patients with autonomic dysfunction have worse prognosis, including an increased incidence, of sudden death, than those without autonomic dysfunction. This event may be due to sympathetic imbalance causing disturbances of ventricular repolarization. QT dispersion have recently been demonstrated to reflect dispersion of ventricular refractoriness and is a marker of arrhythmogenic potential. METHODS: Sixty diabetic patients and 31 normal subjects were studied. All patients had clinical test for cardiovascular autonomic dysfunction by Ewings method and defined as normal, early involved, definitely involved, severely involved and atypical group for 5 validated tests. Resting standard 12-lead electrocardiograms were recorded for measurement of QT dispersion, defined as the difference of longest QT interval and shortest QT interval, and corrected for heart rate using Bazetts formula. RESULTS: Twenty-seven dIiabetic patient were abnormal in cardiovascular autonomic function tests. In these patients corrected QT dispersion (QTc) were significantly longer compared to that 33 patients without autonomic dysfunction(47.4+14.7 vs 22.6+ 8.1msec p<0.001). And also there was significant difference of QTc dispersion between normal subject and diabetic patients with autonomic neuropathy group(20.5+9.2 vs 47.4+14.7msec p<0.001). But there was no difference between normal control and diabetic patients without autonomic neuropathy group. And QTc dispersion was not related to the presence ot nephropathy, retinopathy or peripheral polyneuropathy. We also found that there was no relationship between the severity of autonomic neuropathy and degree of Q7c dispersion. CONCLUSION: We concluded that QTc dispersion may be a good method for evaluation of cardiovascular autonomic neuropathy and increased QTc dispersion may be one of the markers of arrhythmia in diabetic patients with autonomic neuropathy.

BACKGROUND
Autonomic neuropathy was detected in some diabetics with symmetric peripheral neuropathy, a common complication of diabetes mellitus that may be associated with considerable morbidity. There has been known to be similarity of pathogenic mechanism in two neuropathies. Then we examined nerve conduction velocity and cardiovascular autonomic function tests. We studied relationship between peripheral and cardiovascular autonomic neuropathy in non-insulin dependent diabetics. METHODS: We studied 166 patients with or witbout peripheral neuropathy who had been diagnosed as non-insulin dependent diabetes mellitus. We examined nerve conduction tests to assess diabetic peripheral neuropathy and classified them into 4 groups aecording to neuropathic symptoms and results of nerve conduction tests. We examined five cardiovascular autonomic function tests by Ewing's methods. RESULTS: 1. The duration of diabetes mellitus was significantly longer in the group of cliabetics with neuropathic symptoms and abnormal findings in the nerve conduction velocity tests than the other groups. The level of blood glucose was significantly higher in the group of diabetics with neuropathic symptoms and findings than the other groups. 2. In the 5 cardiovascular autonomic function tests, heart rate response to deep breathing and Valsalva maneuver had significant differences between the diabetic group with peripheral neuropathy and the other groups. 3. The frequency and severity of autonomic neuropathy were higher in the group with peripheral neuro-pathic symptoms and findings than the other groups without neuropathic syrnptoms and findings. There was an overall significant relationship between sensorirnotor neural function and autonomic function. 4. There was no association between peripheral neuropathy and nephropathy although peripheral neuropathy was related with retinopathy. CONCLUSION: Diabetic peripheral neuropathy accompanies autonomic neuropathy. Then, this result suggests that there is the relationship between peripheral and cardiovascular autonomic neuropathy.
