Managing diabetes: current strategies.

BACKGROUND: Diabetes is a significant cause for morbidity and mortality in developed countries. Current diabetes treatment goals involve more than normalizing glucose levels and preventing the acute effects of high or low glucose levels. RESULTS: People with diabetes are hospitalized 1.5 to 3 times more often than people who do not have diabetes, have 2 to 4 times greater risk of atherosclerotic disease, and have the highest incidence of adult blindness, chronic renal failure, and nontraumatic amputations. CONCLUSION: The challenge that faces clinicians who care for people with diabetes is to prevent--or at least attenuate--the effects of the chronic complications of this disease.

Insulin therapy and the reluctant patient. Overcoming obstacles to success.

When diabetic patients learn that insulin therapy is necessary, they may feel overwhelmed by anticipated changes in lifestyle. The key to success is to realize that every person with diabetes has individual needs and that these must be assessed, addressed, and accommodated. Better diabetes control will be the result.

Diabetes Mellitus, Type 1↗

Fine-tuning insulin therapy.

It is now possible to mimic normal insulin action more precisely than ever before with physiologic treatment programs using self-monitoring of blood glucose levels and newer insulins with more predictable action. Physiologic programs are more effective for both insulin-dependent (type I) and non-insulin-dependent (type II) diabetes mellitus. With type I diabetes, conventional fixed-dose programs are often quite effective, but some patients may prefer the greater flexibility of intensive insulin therapy. Studies are under way that should provide further guidance on use of intensive insulin therapy. The decade of the 1990s should see additional improvements in insulin preparations and in methods of delivery and monitoring, so that patients can be treated with programs that are not only safer but more physiologic, more comfortable, and more effective in maintaining long-term good health.

Rapid onset of severe retinopathy, cataracts and neuropathy in young patients with diabetes mellitus.

It is rare for young diabetic patients to develop severe complications in the first years of their disease. We describe three patients, aged 14-23 years who developed cataracts and severe retinopathy within one to five years of diagnosis of diabetes. During the same period, one patient developed peripheral neuropathy and a second severe autonomic neuropathy. Rapid development of chronic complications in these patients raises the possibility that there may be a subset of patients with unusual susceptibility to complications. We re-emphasize the need for vigilant monitoring for complications in young diabetic patients, even in the first few years of their disease. In particular, young patients with visual complaints should be evaluated carefully for evidence of treatable eye disease.

An adrenocorticotropic hormone-producing pheochromocytoma: diagnostic and immunohistochemical studies.

A patient is described with Cushing's syndrome owing to a pheochromocytoma that was producing adrenocorticotropic hormone. Preoperative diagnosis was suggested by finding bilateral adrenocortical hyperplasia plus a separate unilateral adrenal medullary mass and was confirmed laboratory studies. Proper preoperative preparation was followed by a unilateral adrenalectomy and a clinical cure of both conditions. Immunohistochemical studies confirmed the ectopic production of adrenocorticotropic hormone and its related peptides more thoroughly than previous reports. The hormone production appeared clinically and immunocytochemically to resemble pituitary Cushing's disease more closely than ectopic production of adrenocorticotropic hormone by other tumors. The clinical aspects of this case illustrate the importance of proper preoperative recognition to reduce the high known percentage of morbidity and mortality.

Experience with penile prostheses in the treatment of impotence in diabetic men.

Increasing use of penile prostheses to treat impotence in diabetic men warrants a detailed assessment of functional and subjective outcomes within this group. This study uses record review and patient-partner questionnaire techniques to examine this population and evaluate postoperative satisfaction in terms of changes in patterns of sexual activity, health status, and complication rates. The satisfaction rates among patients and partners were 81% and 83%, respectively. Frequency of sexual activity was increased, and physical enjoyment was improved among satisfied recipients. Most postoperative complications were treatable and led to dissatisfaction only if they were irreparable. Most prostheses are therefore being used successfully. We recommend that impotent diabetic men be informed of the availability of prosthetic implants.

Impact of transfer from animal-source insulins to biosynthetic human insulin (rDNA E coli) in patients with diabetes mellitus.

Six hundred forty-eight patients (50.5% men; 49.5% women) with diabetes mellitus on animal-source insulin therapy for at least five years were studied. In this patient population, approximately 68.7% had Type I insulin-dependent diabetes mellitus and 31.3% had Type II noninsulin-dependent diabetes mellitus, nonetheless requiring insulin therapy. Patients were voluntarily transferred from animal-source insulin to biosynthetic human insulin derived by recombinant DNA technology from genetically altered Escherichia coli [human insulin (rDNAE coli)] and were monitored regularly thereafter. At a mean interval of 14 months after transfer to human insulin (rDNAE coli), these patients had gained 0.8 kg in body weight (P less than 0.01). There was a significant decline in systolic (P less than 0.01) but not in diastolic blood pressure. Insulin requirements while on animal-source insulin averaged 47.6 +/- 22.9 U/day (mean +/- SD); this requirement was not significantly different after transfer to human insulin (rDNAE coli) (47.0 +/- 21.2 U/day). The distribution of regular and modified insulin types prescribed did not change after patients were transferred from animal-source insulin to human insulin (rDNAE coli). However, a significant increase in the number of insulin injections from 1.79 +/- 0.59 to 1.96 +/- 0.61 injections/day was observed (P less than 0.001). Fasting glucose levels declined significantly from 202 +/- 87 mg/dl on animal-source insulin to 178 +/- 66 mg/dl on human insulin (rDNAE coli) (P less than 0.001). Postprandial glucose levels (at two hours) also declined from 227 +/- 83 mg/dl to 212 +/- 80 mg/dl. Glycosylated hemoglobin (HbA1c) decreased from 9.57 +/- 2.01% while taking animal insulin to 8.97 +/- 2.00% on human insulin (rDNAE coli) (P less than 0.001) Serum cholesterol and triglyceride levels insulin (rDNAE coli). Serum high-density lipoprotein cholesterol (HDL-cholesterol) levels increased from 54.2 +/- 15.1 mg/dl on animal insulin to 57.2 +/- 15.5 mg/dl on human insulin (rDNAE coli) (P less than 0.001). These data demonstrate that transfer of patients from animal-source insulins to human insulin (rDNAE coli) was associated with: (1) an improvement in glycemic control parameters; (2) a slight increase in the number of insulin injections in some patients, but no overall alteration in insulin requirements; and (3) no adverse trends in indicators of cardiovascular risks, such as serum lipids. Indeed, overall cardiovascular risk may have declined not only as a result of improvement in glycemic control, but also owing to a reduction in systolic blood pressure and an elevation in HDL-cholesterol levels.
