Bone loss and bone turnover in diabetes.

There have been conflicting reports about the effect of diabetes on bone density. In 1978, we studied 109 patients, 46 with type I and 63 with type II diabetes; approximately 12 years later we restudied 35 of the 66 surviving patients. In the original study, radial bone density did not differ significantly between patients with either type of diabetes but was significantly lower than in nondiabetic control subjects. In eight osteopenic patients, bone formation rate and other histological indexes of osteoblast recruitment and function were markedly depressed compared with those in nondiabetic control subjects. In patients remeasured approximately 2.5 years (41 patients) and approximately 12.5 years (35 patients) after baseline, bone loss had continued at the expected rate in patients with type I diabetes, with maintenance of the same deficit, but was slower than expected in patients with type II diabetes, such that the initial deficit had been completely corrected. In six of the eight patients who had undergone bone biopsy, one with type I and five with type II diabetes, the mean bone mineral density z-score of the spine and femoral neck approximately 12 years later was > 0 and in one subject was significantly higher than normal at both sites. Based on these data and on previous studies, we propose that in patients with diabetes, low bone formation retards bone accumulation during growth, metabolic effects of poor glycemic control lead to increased bone resorption and bone loss in young adults, and low bone turnover retards age-related bone loss.(ABSTRACT TRUNCATED AT 250 WORDS)

Ongoing assessment of health status in patients with diabetes mellitus.

In 1990, the Division of Endocrinology and Metabolism of Henry Ford Hospital established an Outcomes Management data base for patients with Type I and Type II diabetes. A first cohort of 117 patients completed a baseline and 6-month follow-up assessment; a second cohort of 116 patients completed the baseline assessment. Assessment at each time point includes: the Short Form--36 Questions (SF-36) health status instrument; a set of clinical variables known as the Diabetes TyPE scale Form 2.2 abstracted from the medical record; and the physicians' ratings of patient's health status along the major dimensions of the SF-36. Success with both face-to-face and mailed administration of the SF-36 has been good, with response rates of over 85% using both methods. Comparison of patient and physician ratings of patient health status indicated a significant discrepancy on ratings of general health status, with physicians' ratings higher than those of patients themselves. "Tight" glycemic control (as measured by glycosylated hemoglobin) was associated with somewhat lower ratings on the various SF-36 dimensions for all patients in the first cohort and for Type I patients in the second cohort. However, this effect did not seem to be attributable to those features of a complex regimen used to achieve tight control, but rather reflected a complex combination of age, education level, and number of daily injections associated with achieving good control.

The why and wherefore of fructosamine.

GH and FA are useful monitors in the care of diabetic patients. For most situations, GH is the preferred test and should be routinely monitored. FA should be reserved for exceptional situations in which blood glucose control over one to two weeks must be assessed or in patients with a hemoglobinopathy. Patients with diabetes should be advised of their present GH level and the preferred goal.

An ambulatory approach to self-care of diabetes.

Managing the insulin-requiring diabetic patient in an ambulatory setting includes metabolic regulation of the diabetes and education in its self-care. Means of achieving these goals include structured group or one-on-one individualized sessions. Third party policies relating to ambulatory care are challenged and their need for fiscal support emphasized. During the coming decade, diabetic patients should 1) have access to ambulatory care programs for metabolic regulation and education in self-care, 2) expect third party support of these programs, and 3) heighten their own priorities on diabetes care to ensure quality management of their diabetes.

Microalbuminuria in clinical practice.

Albumin excretion rate measured by new immunoassays and semiquantitative tests is advocated as a means for early detection of diabetic nephropathy. We determined albumin excretion rate in 276 patients. Albumin excretion rate was normal in 66%, within the microalbuminuric range in 27%, and within the macroproteinuric range in 7%. Significant predictors of albumin excretion rate included presence of hypertension and glycosylated hemoglobin level in type I diabetes mellitus, and years since diagnosis in type II diabetes mellitus. A semiquantitative test was deemed to be of limited diagnostic value. We conclude that testing for early diabetic nephropathy in routine clinical practice gives valuable information and that determination by a quantitative immunoassay based on a single 24-hour urine sample is preferable. The optimal frequency of screening and the levels that determine progressive renal disease have yet to be established.

Capsaicin: a therapeutic option for painful diabetic neuropathy.

Fifteen patients with diabetes mellitus who had painful diabetic neuropathy (PDN) were enrolled in a double-blind study to test the safety and efficacy of capsaicin 0.075% (Axsain, Genderm, Northbrook, IL). Twelve of the 15 patients completed the eight-week study. Nine of the 12 patients reported symptomatic relief; of these nine, five used the drug and four used the vehicle. The three patients who reported no relief of symptoms applied the vehicle. Capsaicin is potentially effective when burning pain is a major symptom of PDN. The side effects of capsaicin were limited and minimal. This agent should be considered by clinicians for treatment of PDN.

Evaluation of the insulin jet injector as a potential source of infection.

In recent years jet injection of insulin has been widely used by patients with diabetes mellitus. Jet injectors may become contaminated by bacteria because of repeated use without cleaning; cleansing every 2 weeks is recommended. We investigated the occurrence of bacterial contamination by culturing jet injectors in everyday use by 19 patients with diabetes. Swabs from the interior chambers were cultured on blood agar plates. Only one of 20 cultures yielded bacterial growth, and the organism recovered was a presumed contaminant that could not be identified as any common pathogen. No study patient, nor any of more than 70 patients whom we instructed in jet injection, showed any clinical evidence of infection attributable to jet injector use. Jet injectors are unlikely to become colonized by bacteria or to cause infection in patients using them for insulin administration. The low rate of colonization may be due to the antibacterial preservatives added to commercial preparations of insulin. Additional data based on larger numbers of patients would be useful in further clarifying the risk of infection associated with jet injectors.

Motor vehicles, hypoglycemia, and diabetic drivers.

Individuals with diabetes are increasingly persuing employment in fields previously restricted as a result of the development of chronic complications. Improved glycemic control resulting from use of sophisticated insulin delivery and monitoring systems has also led to the recognition of recurrent hypoglycemia as a potential major clinical and occupational hazard. No data concerning the occupational safety of individuals with insulin-treated diabetes mellitus (ITDM) are available. We review the literature on diabetic drivers in an effort to examine the impact of certification of ITDMs as commercial drivers. In the absence of significant worldwide experience with ITDMs as commercial drivers, the discussion is necessarily based on projected accident rates derived from data on frequency of hypoglycemia. These studies are universally flawed by variable definitions of hypoglycemia, ascertainment bias, and patient selection. They do, however, provide a worst-case/best-case scenario for discussion. It is imperative that any expansion of employment opportunities for ITDMs be followed carefully with prospective studies to assess the impact on public safety.

Evaluation of a new chemical dip strip for detecting ketonemia in the emergency setting.

The utility of a new urine dipstick, Chemstrip uK, was evaluated using serum in place of urine to quantify serum ketones in 29 acutely ill patients with suspected ketosis treated in the emergency department. The serum Chemstrip uK method accurately predicted the level of ketonemia as assessed by the Acetest tablet method (r = .94; P less than .0001). There were no false-negative and no false-positive results. The use of this strip is recommended for evaluating subjects with suspected ketosis.

Outpatient regulation of the insulin-requiring person with diabetes (an alternative to hospitalization).

One hundred and six insulin-requiring diabetic patients were randomly recruited to a pilot out-patient diabetes regulation and self-care program. The program was designed to offer an alternative to hospitalization. 89 patients completed the 5-day program. Fasting plasma glucose values at 5 days were significantly lower than initial levels (263 +/- 73 mg/dl vs 156 +/- 60 mg/dl; p-value less than 0.001). Long-term diabetic control was similarly improved at 6 months after entry when total glycosylated hemoglobin levels were significantly lower than initial values (13.8 +/- 2.8% vs 11.1 +/- 2.4%; p-value less than 0.0005). 17 patients failed to complete the program. Only four patients of the 89 were subsequently hospitalized with diabetes-related conditions. 445 hospital days were saved during the study period with calculated total dollar savings over $90,000. It is suggested that a structured out-patient program for diabetes regulation and self-care can be successfully developed and carried out at a significantly lower cost than hospitalization. Third party payors should take cognizance of these programs and appropriately include them in their health care coverage.

Classification and pathogenesis of the diabetes syndrome: a historical perspective.

Once thought to be solely a disease of insulin deficiency, diabetes mellitus now is recognized as a disorder with multiple pathogenetic mechanisms. Newer terminology identifies those uncommon patients with true insulin deficiency as having insulin-dependent diabetes (IDDM), while the majority of patients with diabetes have some residual insulin secretion but may have a disorder of insulin receptor number or affinity. These patients have non-insulin dependent diabetes (NIDDM). Other patients may have gestational diabetes, impaired glucose tolerance, a potential for glucose intolerance, or a previous history of diabetes. A few patients will have diabetes secondary to a known cause, such as pancreatitis or Cushing's syndrome. Understanding this nosological approach to diabetes should enhance the clinician's decisions regarding therapy.
