Non-insulin-dependent diabetes mellitus (NIDDM) is a major health concern for clinicians who are responsible for the care of an aging population. The relationship between hyperglycemia and the chronic complications of retinopathy, nephropathy, and neuropathy has been established in patients with insulin-dependent diabetes mellitus, and it is extremely likely that such a relationship exists in patients with NIDDM as well. Diet and exercise are the cornerstone for the management of NIDDM. The assessment of glycemic control should determine which patients with NIDDM need more aggressive intervention to control hyperglycemia. Pharmacologic treatment options include oral administration of the sulfonylureas, a biguanide, and an alpha-glucosidase inhibitor and subcutaneous administration of insulin. Extensive education about diabetes and self-monitoring of blood glucose levels are important components in maximizing glycemic control. Additional pharmacologic treatment options are necessary when adequate individualized treatment goals are not attained. The goal of therapy is to prevent the onset or progression of long-term microvascular and macrovascular complications. In this review, we present the therapeutic options and outline our approach to the pharmacologic treatment of NIDDM. Relevant medical literature on each treatment modality is reviewed, and the cost of therapy with use of each medication is provided.

Glycosylated haemoglobins and weights were recorded for 200 consecutive diabetic clinic attenders seen yearly for 5 years, 76 of whom were also seen up to 10 years from diagnosis of type 2 diabetes, representing 1380 patient years. Weight fluctuation (> 3 kg) was associated with increased final prevalence of hypertension, macroalbuminaemia and a raised creatinine (P < 0.002) but this relationship was abolished by correction for higher initial weight. Average glycaemia over 5/10 years [itself related to initial weight in women on tablets (N = 53) but not others, and to waist but not waist/hip ratio], correlated with prevalence and severity of retinopathy (N = 200; r = 0.38, P < 0.0006) seen also in the subgroup of patients on tablets (N = 145, P < 0.006). At HbA1 levels > 10.5% an increased prevalence of retinopathy was seen in those on insulin (N = 37, P < 0.001) and an increased prevalence of peripheral vascular disease was seen in men but not women (x2 = 2.87, P < 0.01) as well as in the prevalence of neuropathy. These findings suggest that good glycaemic control is of value in type 2 diabetes and less easily achieved in obesity.

50 Patients of diabetes mellitus (both IDDM and NIDDM) were selected with typical symptoms, signs and positive bed side tests of autonomic neuropathy. All the patients were followed for three months during which strict metabolic control was achieved by routine treatment with oral hypoglycaemic agents and/or insulin, simply by change in their previous treatment dosages and better attention to diet and physical activity. 22% patients showed significant improvement in symptoms of autonomic neuropathy. 42% showed partial improvement and 36% patients did not show any improvement. Improvement in objective test score was significant in 18%, partial in 46% and insignificant in 36%. Improvement in neuropathy did not correlate with HbA1C levels. 36% patients did not show any subjective or objective improvement in autonomic neuropathy inspite of good glycaemic control as indicated by normal HbA1C levels in them.

The presence of opioid peptides within pancreatic islets in several animal species and in humans suggests that these peptides could play a role in pancreatic endocrine secretion, influencing glucose metabolism. We measured plasma met-enkephalin (met-Enk) levels in eight neuropathic (four with insulin-dependent diabetes mellitus [IDDM] and four with non-insulin-dependent diabetes mellitus [NIDDM]) and eight nonneuropathic (four IDDM and four NIDDM) diabetic patients to study met-Enk secretion in diabetic patients with asymptomatic autonomic neuropathy. Plasma met-Enk levels were significantly lower in neuropathic compared with nonneuropathic patients both in the IDDM group (28.7 +/- 4.8 v 61.6 +/- 4.1 pg/mL, P < .0025) and in the NIDDM group (26.5 +/- 3.6 v 44.3 +/- 4.6 pg/mL, P < .0125). This study suggests that the presence of neuropathy in diabetic patients, even if asymptomatic, is associated with a significant decrease of plasma met-Enk levels, thus contributing to a worsening of metabolic control under stress conditions.

The prevalence of vascular complications was assessed in 726 South Indian non-insulin dependent diabetes mellitus (NIDDM) patients with over 25 years' duration of diabetes. Retinopathy was detected in 52.0% of patients which included 41.7% with non-proliferative and 10.3% with proliferative diabetic retinopathy. Nephropathy was present in 12.7% and neuropathy in 69.8% of patients. While 32.8% of patients had ischaemic heart disease, the prevalence of peripheral vascular disease was only 15.4%. Multivariate logistic regression analyses showed that serum creatinine was associated with retinopathy, creatinine and post-prandial plasma glucose with nephropathy and post-prandial plasma glucose and age with neuropathy. This is one of the first reports on vascular complications in long-term diabetes from the Indian sub-continent.

The aim of this cross-sectional study was to establish the prevalence of renal involvement and to identify associations with its most important possible risk factors in a group of patients with Type II diabetes mellitus, representative of the population living in Catalonia. One thousand two hundred and three patients (47% males, mean age: 61 +/- 6 years, diabetes duration 9 +/- 6 years) were studied. Overnight urine samples were collected to determine urinary albumin excretion (UAE). If UAE was > 15 micrograms/min, a new 24-h urine collection for UAE measurement to establish the existence of microalbuminuria (20-200 micrograms/min) or macroalbuminuria (> 200 micrograms/min) was obtained. Clinic and metabolic evaluations were also performed. The prevalence (%) of microalbuminuria, macroalbuminuria and hypertension were, respectively, 23. 1, 5.4 and 42. In comparison with normoalbuminurics, patients with microalbuminuria were predominately male (P < 0.03), with a significantly higher systolic (P < 0.001) and diastolic (P < 0.001) blood pressure and body mass index (P < 0.001). The prevalence of smokers (former + current) was higher in patients with microalbuminuria (43 vs 32%, P < 0.025). Moreover, patients with nephropathy had more prevalence of retinopathy (P < 0.001), neuropathy (P < 0.001), peripheral angiopathy (P < 0.001) and coronary disease (P < 0.001). The prevalence of microalbuminuria in Type II diabetes in Catalonia is similar to that observed in other european countries. The existence of microalbuminuria is associated with several diabetic complications, as well as tobacco consumption and obesity.

The ABCD (Appropriate Blood Pressure Control in Diabetes) trial is a large, prospective, randomized clinical trial designed to compare the effects of intensive with moderate blood pressure control on the prevention and progression of diabetic nephropathy, retinopathy, cardiovascular disease, and neuropathy in non-insulin-dependent diabetes (NIDDM). The secondary objective is to determine equivalency of the effects of a calcium channel blocker (nisoldipine) and of an angiotensin-converting enzyme inhibitor (enalapril) as a first-line antihypertensive agent in the prevention and/or progression of these diabetic vascular complications. The study consists of two study populations: a hypertensive one (diastolic blood pressure of > or = 90.0 mm Hg at the time of randomization) and a normotensive one (diastolic blood pressure of 80.0-89.0 mm Hg at the time of randomization). A total of 950 men and women aged 40-74 years were randomized and are being followed for 5 years at a single center. There were 470 randomized participants in the hypertensive population and 480 randomized participants in the normotensive population. This report summarizes the demographic, biochemical, and clinical characteristics of the randomized patients at the time of entry into the trial and evaluates the balance between the treatment groups within each population.

In this immunohistochemical study we investigated the expression of low-affinity NGF receptor (p75NGFR) in peripheral nerves from 16 patients with type I or type II diabetes mellitus. Fourteen nerves from age- and sex-matched normal individuals and nine nerves from non-diabetic patients with ischemic neuropathy served as controls. All nerve samples were preliminarily examined by standard histology, fiber teasing and electron microscopy. Increased p75NGFR immunoreactivity was detectable within the endoneurium of cross-sections from ischemic and particularly from diabetic nerves. Immuno-teasing demonstrated that p75NGFR immunostaining was distributed along the entire length of isolated nerve fibers undergoing axonal degeneration. Quantitative assessment of p75NGFR immunoreactivity, performed by histospectrophotometry and expressed as percentage of adsorbance, was 21.20 +/- 3.50 in nerves from diabetic patients, 13.35 +/- 3.62 in nerves from non-diabetic patients with ischemic neuropathy and 9.02 +/- 2.75 in normal controls. The increased expression of p75NGFR in diabetic nerves is consistent with an axonopathic defect and further suggests involvement of NGF and other neurotrophins in the pathogenesis of human diabetic neuropathy.

Isolated hypoaldosteronism is found in 75% diabetics where the disease has persisted for 10 or more years. Sporadically it is found in congenital autonomous neuropathy, in acute glomerulonephritis, in gouty kidney, tubulointerstitial nephritis, after transplantation of the kidney, on mytomycin etc. During dynamic testing of the response of plasma renin activity and aldosterone to the administration of furosemide and a vertical position in diabetics a significantly reduced response was recorded as compared with non-diabetic hypertonic subjects. In 18.3% no response was observed (decompensated form of IHH). Diabetic hypertonics behaved like control hypertonics on long-term beta-blocker treatment. In the decompensated form of IHH after administration of drugs interfering with the activity of SNS-RAAS activity (ACEI, spirolactone etc.) a hyperkalaemic crisis may develop which threatens the patient with acidosis, dehydration, myoplegia, muscular spasms, however, in particular with fatal disorders of the cardiac rhythm. A similar effect may be exerted also by blockers of prostaglandin synthetase (non-steroid antirheumatics) and other drugs. The cause of IHH in diabetics is the coincidence of several pathogenic factors: 1. hypersecretion of ANF with hyperosmolar hyperglycaemic hypervolaemia and hyperfiltration already at the onset of DN, 2. early development of autonomous neuropathy of the sympathetic nerve, 3. reduced renin and prostaglandin formation already in the early stages of DN, 4. reduced extrarenal isorenin formation, 5. reduced conversion of prorenin into active renin, 6. reduced reactivity of the zona glomerulosa to AII, hyperkalaemia and ACTH for its functional reconstruction as a result of periodic activation of contraregulative hormones by fluctuations of the blood sugar level in diabetic patients, 7. reduced response of the distal renal tubule to aldosterone because of tubulointerstitial changes. IHH is thus another serious but rarely diagnosed late complication of diabetes which depends only partly on the stage of DN. It must be, however, diagnosed and respected with regard to the selection of drugs for the treatment of arterial hypertension and the syndrome of insulin resistance and the 5H syndrome resp., i.e. the association of hyperinsulinism which compensates insulin resistance with hyperglycaemia (NIDDM), hypertension, hyperlipoproteinaemia and hirsutism in women (so-called Stein-Leventhal syndrome).

Relationship of transcutaneous oxygen pressure (TcP(O2)) to glycemic control and diabetic complications was investigated in patients with non-insulin dependent diabetes mellitus. TcP(O2) was measured in 103 patients with non-insulin dependent diabetes mellitus. Correlation of TcP(O2) to HbA1c, fasting blood sugar (FBS), age, duration of diabetes, serum lipids, hypertension, and diabetic complications were examined. We divided the patients into three groups according to their glycemic control: good control group (HbA1c < 7.0%), fair control group (HbA1c, 7.0-8.9%) and poor control group (HbA1c > or = 9.0). We compared TcP(O2) of these three groups with 19 non-diabetic controls. In 103 patients, TcP(O2) at baseline correlated with HbA1c, FBS and age (P < 0.001, P < 0.01 and P < 0.05, respectively), but did not correlate with duration of diabetes mellitus, neuropathy, nephropathy or retinopathy. TcP(O2) of good and fair control group was not reduced comparing to the non-diabetic control (63 +/- 11, 59 +/- 10 and 64 +/- 12 mmHg, respectively). The poor control group had significantly reduced TcP(O2) (55 +/- 10 mmHg) comparing to non-diabetic control (P < 0.005) and good control group (P < 0.005). Furthermore, in an independent study, TcP(O2), arterial oxygen pressure (Pa(O2)), oxygen pressure of dorsal pedal vein (PV(O2)) and erythrocyte 2,3-diphosphoglycerate (2,3-DPG) in eight patients with poor glycemic control were followed prospectively. Six patients with improvement of glycemic control showed a significant increase of TcP(O2) and Pa(O2) (P < 0.001 and P < 0.005, respectively). However, two patients without improvement of hyperglycemia had no change in TcP(O2) and Pa(O2). PV(O2) and 2,3-DPG levels of erythrocytes were not changed in six patients. These findings suggest that tissue oxygenation in diabetic patients was deteriorated in relation to hyperglycemia and was reversed with glycemic control. Improvement of Pa(O2) might contribute partly to the increase of TcP(O2).
