Abstract
OBJECTIVE To evaluate the compliance of the service of glucometry in drugstores in the department of Santander - Colombia. METHODS Cross-sectional observational study. An assessment instrument based on the normativity and validated by experts was used. RESULTS The poll was applied to 68 drugstores. The results were categorized as follows: human resources, equipment, infrastructure, documentation - registration, and surveillance and control processes. In the first category, shortcomings related to the academic training of the staff in charge of the drugstore were identified, with a compliance percentage of 66,2% and in the training of personnel in the management of the glucometry equipment, 35,3%. In general, the knowledge of the regulations by the staff was 36,8%. In the equipment and infrastructure categories, a level of compliance of more than 50% is evident for all items, xcept in those related to calibration equipment. In the fourth category, specifically in documentation and registration, the levels of regulatory compliance are less than 50% in all items, except in the one related with the information that is offered to the patient during the procedure. The results show a failure in the surveillance and control processes, where only 57,4% of the establishments confirm inspection visits. CONCLUSIONS The results of this study reveal widespread ignorance of the regulations in drugstores that provide the glucometry service; consequently, not all regulatory requirements are met. Promoting training programs and strengthening the culture of self-evaluation guarantees safe processes for the patient.

Abstract
For primary care providers, using insulin can present challenges that can be met by a straightforward approach using the following principles. Depending on when it is injected, each component of the insulin regimen has a maximal effect on a specific period of the 24-hour cycle (e.g., overnight, morning, afternoon, or evening). The glucose pattern in that period determines whether the dose of that component of the insulin regimen requires adjusting. Regarding which insulin types and insulin regimens to use, human insulin (NPH and regular) is as effective as analog insulins, and a two-injection intensified insulin regimen is as effective as a four-injection regimen.

Abstract
BACKGROUND Type 1 diabetes is a metabolic disorder resulting from a defect in insulin secretion. Onset of type 1 diabetes mellitus may occur at any age and it is one of the most common chronic diseases of childhood and adolescence. Since there are no interventions known to prevent onset, it is vital that effective treatment regimes are available. Glycaemic control is maintained by replacement of insulin and may be in the form of 'conventional' insulin therapy (multiple injections per day) or continuous subcutaneous insulin infusion (CSII). OBJECTIVES To assess the effects of CSII compared to multiple insulin injections (MI) in people with type 1 diabetes mellitus. SEARCH STRATEGY Studies were obtained from electronic searches of The Cochrane Library, MEDLINE, EMBASE and CINAHL. SELECTION CRITERIA Studies were included if they were randomised controlled trials comparing CSII with three or more insulin injections per day (MI) in people with type 1 diabetes mellitus. DATA COLLECTION AND ANALYSIS Two authors independently assessed risk of bias and extracted characteristics of included studies. Authors contacted study investigators to obtain missing information. Generic inverse variance meta-analyses using a random-effects model were performed. MAIN RESULTS Twenty three studies randomised 976 participants with type 1 diabetes to either intervention. There was a statistically significant difference in glycosylated haemoglobin A1c (HbA1c) favouring CSII (weighted mean difference -0.3% (95% confidence interval -0.1 to -0.4). There were no obvious differences between the interventions for non-severe hypoglycaemia, but severe hypoglycaemia appeared to be reduced in those using CSII. Quality of life measures suggest that CSII is preferred over MI. No significant difference was found for weight. Adverse events were not well reported, no information is available on mortality, morbidity and costs. AUTHORS' CONCLUSIONS There is some evidence to suggest that CSII may be better than MI for glycaemic control in people with type 1 diabetes. Non-severe hypoglycaemic events do not appear to be reduced with CSII. There is insufficient evidence regarding adverse events, mortality, morbidity and costs.

Abstract
The influence on glycosylated hemoglobin (HbA1) of formal education as compared with self-monitoring of blood glucose (SMBG) was studied in a randomized 18-month trial. All adult type I diabetics in a community were identified. Forty-one of these patients had had diabetes for 20 years or less. Thirty-seven patients were included in the study and finally randomized into four groups. Ten patients received individual formal education followed by SMBG, eight patients were instructed in SMBG without pre-education, nine patients were given only formal education and 10 patients made up a reference group. Education did not improve the mean HbA1 values. SMBG resulted in a decrease by 2% in HbA1, from 12 to 10% (p less than 0.05). The final HbA1 level, however, did not differ significantly between any of the groups. SMBG was accepted by 80% of the patients. The liability to hypoglycemia was about equal in the four groups. It was concluded that SMBG, but not education, improved metabolic control to a certain degree.

Abstract
We evaluated the feasibility and effectiveness of continuous subcutaneous insulin infusion therapy (CSII) as compared to conventional injection treatment (CIT) in an ordinary diabetic clinic in a one-year randomized crossover study of 65 type I diabetic patients. Home blood glucose levels were lower during CSII (8.6 +/- 0.2 mmol/l, mean +/- SEM) than during CIT (9.1 +/- 0.3 mmol/l, p less than 0.05). During the first six months, HbA1 fell on CSII therapy (from 10.6 +/- 0.4 to 9.7 +/- 0.3%, p less than 0.001), whereas no change occurred during CIT. After the crossover, HbA1 decreased again on CSII (p less than 0.05), but rose in patients shifted from CSII to CIT (p less than 0.05). The fall in glycosylated haemoglobin during CSII correlated with the initial HbA1 level (r = 0.54, p less than 0.001). Ketoacidosis was more common during CSII (16 vs. 2 verified episodes). Hypoglycaemia occurred infrequently, without difference between CSII and CIT. Fifty-six per cent of the patients preferred CSII after the study. In conclusion, while CSII slightly improves the metabolic control, the improvement in the unselected study population is less than previously reported among highly selected patients.

Abstract
OBJECTIVE Despite the demonstrated benefits of glycemic control, patient acceptance of basal/bolus insulin therapy for type 1 diabetes has been slow. We investigated whether a basal/bolus insulin regimen involving rapid-acting, dry powder, inhaled insulin could provide glycemic control comparable with a basal/bolus subcutaneous regimen. RESEARCH DESIGN AND METHODS Patients with type 1 diabetes (ages 12-65 years) received twice-daily subcutaneous NPH insulin and were randomized to premeal inhaled insulin (n = 163) or subcutaneous regular insulin (n = 165) for 6 months. RESULTS Mean glycosylated hemoglobin (A1C) decreased comparably from baseline in the inhaled and subcutaneous insulin groups (-0.3 and -0.1%, respectively; adjusted difference -0.16% [CI -0.34 to 0.01]), with a similar percentage of subjects achieving A1C <7%. Although 2-h postprandial glucose reductions were comparable between the groups, fasting plasma glucose levels declined more in the inhaled than in the subcutaneous insulin group (adjusted difference -39.5 mg/dl [CI -57.5 to -21.6]). Inhaled insulin was associated with a lower overall hypoglycemia rate but higher severe hypoglycemia rate. The overall hypoglycemia rate (episodes/patient-month) was 9.3 (inhaled) vs. 9.9 (subcutaneous) (risk ratio [RR] 0.94 [CI 0.91-0.97]), and the severe hypoglycemia rate (episodes/100 patient-months) was 6.5 vs. 3.3 (RR 2.00 [CI 1.28-3.12]). Increased insulin antibody serum binding without associated clinical manifestations occurred in the inhaled insulin group. Pulmonary function between the groups was comparable, except for a decline in carbon monoxide-diffusing capacity in the inhaled insulin group without any clinical correlates. CONCLUSIONS Inhaled insulin may provide an alternative for the management of type 1 diabetes as part of a basal/bolus strategy in patients who are unwilling or unable to use preprandial insulin injections.

Abstract
Around 25% of the adult Type 1 diabetes population is in persistent poor glycaemic control and thus at increased risk of developing microvascular complications. We here discuss correlates of long-standing poor glycaemic control and review the efficacy of clinical strategies designed to overcome persistent poor control. Only a few studies have identified determinants and correlates of long-standing poor glycaemic control in Type 1 diabetes. There is some evidence implicating genetic factors, as well as lower economic status, and psychological factors, including lack of motivation, emotional distress, depression and eating disorders. Ways of improving glycaemic control include strategies to enable self-management, e.g. motivational strategies, coping-orientated education, psychosocial therapies, and/or intensifying insulin injection therapy plus continuous subcutaneous insulin infusion. Long-standing poor glycaemic control appears to be a heterogeneous and complex phenomenon, for which there is no simple, single solution. Comprehensive psycho-medical assessment in diabetes care may prove useful in tailoring interventions. Further research is warranted, to increase our understanding how psychosocial and biomedical factors, separately and in interaction, determine poor outcomes in Type 1 diabetes.

Abstract
OBJECTIVE To conduct a meta-analysis of the metabolic and psychosocial impact of continuous subcutaneous insulin infusion (CSII) therapy on adults, adolescents, and children. RESEARCH DESIGN AND METHODS Studies were identified and data regarding study design, year of publication, sample size, patient's age, diabetes duration, and duration of CSII therapy were collected. Means and SDs for glycohemoglobin, blood glucose, insulin dosages, and body weight for CSII and comparison conditions were subjected to meta-analytic procedures. Data regarding pump complications and psychosocial functioning were reviewed descriptively. RESULTS A total of 52 studies, consisting of 1,547 patients, were included in the meta-analysis. Results indicate that CSII therapy is associated with significant improvements in glycemic control (decreased glycohemoglobin and mean blood glucose). A descriptive review of potential complications of CSII use (e.g., hypoglycemia, diabetic ketoacidosis [DKA], pump malfunction, and site infections) suggests a decreased frequency of hypoglycemic episodes but an increased frequency of DKA in studies published before 1993. CONCLUSIONS CSII therapy is associated with improved glycemic control compared with traditional insulin therapies (conventional therapy and multiple daily injections) and does not appear to be associated with significant adverse outcomes. Additional studies are needed to further examine the relative risks of CSII therapy, including the potential psychosocial impact of this technologically advanced therapy.

Abstract
AIMS To compare glycaemic control, occurrence of acute complications, and diabetes-specific quality of life in Type 1 diabetic patients (on intensified conventional insulin treatment (ICT)) before and after initiation of CSII. METHODS One hundred and three patients (58 women) started CSII between October 1995 and April 1999 in our department. The indication for CSII was optimization of metabolic control and improvement of flexibility of life style (OF group) in 60 patients (58%), and prevention of severe hypoglycaemia (HY group) in 43 patients. Mean age at initiation of CSII was 33 +/- 11 years (OF 33 +/- 10, HY 33 +/- 11 (mean +/- sd)), diabetes duration 18 +/- 9 years (OF 16 +/- 9, HY 20 +/- 9). Three patients stopped CSII, mean duration of CSII of the remaining 100 patients was 1.8 +/- 1.2 years. The occurrence of hypoglycaemia, ketoacidosis and skin abscesses was assessed retrospectively for the 12 months before starting CSII, and recorded continuously during CSII. Quality of life was assessed with a validated, diabetes-specific questionnaire before and after CSII in 50 patients. RESULTS The incidence of serious hypoglycaemia (any external help) was reduced from 1.23 (OF 0.0; HY 2.93) during ICT to 0.29 cases/patient per year (OF 0.09; HY 0.55) during CSII. The incidence of severe hypoglycaemia (SH) (treated with i.v. glucose or glucagon injection) fell from 0.70 (OF 0.0; SH 1.67) during ICT to 0.06 cases/patient per year (OF 0.02; HY 0.12) during CSII. HbA1c improved from 7.7 +/- 1.1% to 7.2 +/- 1.0% (P < 0.001) (OF 7.8% vs. 7.2%; HY 7.6% vs. 7.2%). During CSII the incidence of abscesses was 0.11 and of ketoacidosis 0.01 cases/patient per year. Quality of life assessments showed significant improvement in all parameters during CSII. CONCLUSIONS In our cohort of Type 1 diabetic patients, we observed a substantial decrease of hypoglycaemia along with a significant fall of HbA1c. Quality of life on CSII was improved when compared with ICT.

Abstract
Continuous subcutaneous insulin infusion (CSII) is used in selected type 1 diabetic subjects to achieve strict blood glucose control. A quarter of a century after its introduction, world-wide use of CSII is increasing. We review the evidence base that justifies this increase, including effectiveness compared with modern intensified insulin injection regimens and concern about possible complications. Review of controlled trials shows that, in most patients, mean blood glucose concentrations and glycated hemoglobin percentages are either slightly lower or similar on CSII versus multiple insulin injections. However, hypoglycemia is markedly less frequent than during intensive injection therapy. Ketoacidosis occurs at the same rate. Nocturnal glycemic control is improved with insulin pumps, and automatic basal rate changes help to minimize a prebreakfast blood glucose increase (the "dawn phenomenon") often seen with injection therapy. Patients with "brittle" diabetes characterized by recurrent ketoacidosis are often not improved by CSII, although there may be exceptions. We argue that explicit clinical indications for CSII are helpful; we suggest the principal indications for health service or health insurance-funded CSII should include frequent, unpredictable hypoglycemia or a marked dawn phenomenon, which persist after attempts to improve control with intensive insulin injection regimens. In any circumstances, candidates for CSII must be motivated, willing and able to undertake pump therapy, and adequately psychologically stable. Some diabetic patients with well-defined clinical problems are likely to benefit substantially from CSII and should not be denied a trial of the treatment. Their number is relatively small, as would therefore be the demand on funds set aside for this purpose.

Abstract
In controlled trials intensified diabetes therapy including multiple insulin injection regimes has been shown to improve glycaemic and microvascular disease outcomes in insulin dependent diabetes but this is not clear in routine outpatient practice. We undertook a pragmatic cross sectional study of 200 patients with Type 1 diabetes aged 18-50 years. There were 108 on two insulin injections/day (conventional) and 92 on four injections/day (multiple) with no significant difference for age, sex, social class, body mass index, diabetes duration, hypoglycaemia rate or complications prevalence. The relationship of insulin injection regime used with diabetes knowledge, psychological factors and glycaemic control outcomes was evaluated. Percent glycated HbA1c concentrations (normal range < 5.5%) were worse in the multiple injection group (7.5 +/- 1.7 vs. 6.8 +/- 1.4%, P < 0.001) (mean +/- SD). Their scores for diabetes knowledge (72.5 +/- 8.2 vs. 69.0 +/- 9.8, P < 0.01) were better but treatment satisfaction (29.9 +/- 5.1 vs. 28.5 +/- 6.1, ns) and well-being (49.1 +/- 10.7 vs. 46.5 +/- 12.7, ns) scores were not. Parameters of perceived locus of control were (multiple v conventional): personal (self), 24.5 +/- 5.0 vs. 22.3 +/- 5.9, P < 0.05; medical (doctor), 11.8 +/- 5.1 vs. 10.8 +/- 5.8, ns; situational (chance), 7.9 +/- 5.1 vs. 8.9 +/- 5.9, ns. In multiple regression of HbA1c versus multiple variables only insulin regime (P < 0.001) was significant. We conclude that in routine clinical practice the use of intensive insulin regimes are associated with worse glycaemic control despite patients being marginally more knowledgeable and self directed.

Abstract
OBJECTIVE To describe glycemia and insulin administration in lactating women with type 1 diabetes and compare their energy intake, lactation onset, and postpartum weight to lactating women without diabetes. DESIGN A prospective observational study conducted at 2, 3, 6, 14, 42, and 84 days postpartum. Insulin dosage and glucose levels after fasting and at 80 and 110 minutes after eating (by measuring capillary blood glucose concentrations and glycated hemoglobin [HbA1c] values) are described for women with type 1 diabetes. Dietary intake, weight, and lactation onset for women with type 1 diabetes are compared with those without the disease. SUBJECTS/SETTING Fourteen lactating women with type 1 diabetes and 25 women without diabetes (control subjects) were recruited from private obstetrician offices and high-risk prenatal clinics at 3 major medical centers. STATISTICAL ANALYSES A repeated-measures 2-factor analysis of variance was used to determine group, time, and interaction effects between women with type 1 diabetes and the control group at 2, 3, 7, 14, 42, and 84 days postpartum. RESULTS Seven women with type 1 diabetes breast-fed through 84 days postpartum, although they perceived later onset of milk and had fasting and postprandial hyperglycemia. Their HbA1c levels increased by 20%, confirming relative hyperglycemia. After adjustment for prepregnancy weight, women with type 1 diabetes consumed 7 kcal fewer per kilogram per day than control subjects. Average insulin dose was returned to prepregnancy levels of 45.3 +/- 3.6 U/d (least square means +/- standard error of the mean) by 1 week. APPLICATION Achieving desired metabolic control during the establishment of lactation is difficult. A better understanding of energy and insulin needs and their relationship to lactation in women with type 1 diabetes is needed.

Abstract
These experiments were undertaken to assess the effects of combined treatment with insulin (designed to partially restore metabolic control) and sorbinil (an aldose reductase inhibitor [ARI]) versus the effects of sorbinil alone or of two insulin regimens providing different degrees of glycemic control on diabetes-induced metabolic derangements and vascular function. Streptozocin-diabetic rats were divided into the following five groups: (1) untreated (D); (2) treated with approximately 1 U NPH insulin/100 g body weight/d administered in one subcutaneous (SC) injection (DI-1); (3) treated with the same total daily dose of insulin administered in two SC injections (DI-2); (4) treated with approximately 0.2 mmol sorbinil in the diet/kg body weight/d (DS); and (5) treated with once-daily insulin plus sorbinil (DSI-1). Two groups of nondiabetic rats, untreated (C) and sorbinil-treated (CS), served as controls. Metabolic parameters were unaffected by sorbinil treatment in controls and diabetics, whereas insulin administration in the diabetics virtually normalized body growth, food consumption, urine volume, and plasma glucose levels, and markedly decreased hemoglobin A1 (HbA1) levels. Two daily injections were more effective than one in improving metabolic control as measured by HbA1 levels. Regional vascular 131I-albumin permeation was increased about twofold to threefold by diabetes in ocular tissues, sciatic nerve, aorta, diaphragm, and new granulation tissue; it was decreased (but not normalized) by insulin treatment in accordance with improved metabolic control, and was completely normalized by sorbinil. 131I-albumin kidney clearance, as well as urinary albumin and IgG excretion, were markedly increased in diabetic rats and were significantly decreased but not completely normalized by sorbinil and by twice-daily insulin treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Patient survival and progression of complications were monitored for 3 years after kidney transplantation in 29 type-1 diabetic patients. Ten age-matched, non-diabetic kidney-transplanted patients served as controls. Five diabetic patients died during follow-up (three cardiovascular events, two infections), three diabetic patients had a non-fatal myocardial infarction and four developed cerebrovascular complications after transplantation. Of the diabetic patients, 69% suffered from proliferative retinopathy before transplantation; 20% of them improved, 65% remained unchanged and 15% deteriorated after transplantation. Motor but not sensory conduction velocity measured from the nervus medianus improved after transplantation. Autonomic neuropathy was observed in 50% of the patients and was unaffected by transplantation. Glycaemic control did not improve significantly during follow-up (HbA1, 10.6 +/- 0.5% before and 9.5 +/- 0.6% 3 years after transplantation). Body weight increased in both diabetic and non-diabetic patients within 3 years after transplantation (from 68 +/- 2 to 77 +/- 6 kg in diabetics, P less than 0.01; from 167 +/- 4 to 77 +/- 6 kg in non-diabetics, P less than 0.01). Subcutaneous fat thickness measured from computer tomography scans of the calf increased in diabetic patients from 5.0 +/- 0.6 to 6.1 +/- 0.9 mm (P less than 0.05). However, the cross-sectional areas of triceps and calf muscles did not increase, suggesting that the increase in body weight was solely due to an increase in fat. It is clear that diabetes-related complications continue to progress and are not influenced by a successful kidney transplant.

Abstract
Glomerular hyperfiltration has been claimed to be a risk factor for the development of diabetic nephropathy. Protein intake and hyperglycemia can both increase GFR in diabetic and normal subjects. Our study was designed to explore the relative importance of short-term changes in protein intake and glycemia on the modulation of renal hemodynamics in insulin-dependent diabetic (IDDM) patients with and without glomerular hyperfiltration. The renal hemodynamic response to a protein challenge was studied in eight hyperfiltering (HF) and eight normofiltering (NF) patients after a three week period of low or normal protein diet (LPD, NPD), each study being conducted twice, in random order, under conditions of prevailing hyperglycemia (H) and euglycemia (E). In HF patients GFR failed to increase significantly in response to protein challenge during NPD under conditions of either H or E (Baseline vs. 2 hr H: 151 +/- 4 vs. 155 +/- 6, NS; E 147 +/- 4 vs. 157 +/- 7 ml/min/1.73 m2, NS). A more normal response was restored following LPD with GFR increasing in all but one patient after challenge during H and in all patients during E (Baseline vs. 2 hr H: 130 +/- 7 vs. 145 +/- 8, P less than 0.07; E: 127 +/- 7 vs. 143 +/- 7 ml/min/1.73 m2, P less than 0.01). Changes in RPF paralleled the changes in GFR and filtration fraction remained stable under all study conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We assessed the long term efficacy of Novopen as a form of insulin administration. Records were obtained on 48 patients who were treated with Novopen between January '86 and October '88. Six patients were excluded due to insufficient data. The study group of 42 patients comprised 22 females and 20 males of average age 33 years (range 17-66). Mean Hb.A1 rose from 10.6% to 12.1% after Novopen therapy, a rise of 14.1%. This rise is both clinically and statistically significant (p less than 0.001; 99% confidence limits 0.59-2.78). Increases in weight and insulin dose were also noted, but did not reach statistical significance. The majority of patients felt Novopen was superior to twice daily insulin in terms of ease of administration (81%) and flexibility of lifestyle (95%), and all who were using Novopen wished to continue with it. More than 50% of patients admitted to altering their dietary habits while using Novopen. Despite continuing patient satisfaction with this form of insulin administration, its long-term use may be associated with sub-optimal metabolic control.

Abstract
To determine the suitability of a single subcutaneous evening injection of human ultralente (UL) as the basal component of an intensive insulin therapy program, insulin concentrations were measured in five insulin-dependent diabetic volunteers over a 40-h period. Each patient had been maintained on a human UL-based program for at least one month prior to the study. All short-acting insulin was withheld during the study. The onset of action of human UL was 2 to 4 h, and a broad, variable peak was observed between 6 and 12 h after each injection. We concluded that human UL does not provide constant basal insulin concentrations. When human UL is considered as part of an intensive insulin therapy program, this potential disadvantage must be weighed against the potential advantage of low antigenicity.

Abstract
During the last two decades new forms of insulin and a better understanding of the physiological insulin secretion profile have led to great changes in insulin therapy. New insulin regimens mimicking the normal insulin secretory pattern, called intensive insulin therapy, and new insulin-delivery systems have been introduced. Self-monitoring of blood glucose levels and the use of glycosylated hemoglobin determination for objective evaluation of long-term control have made the achievement of near normoglycemia a practical goal for most patients taking insulin. 1. New forms of insulin: Beef and pork insulin were replaced by monocomponent pork insulin and now monocomponent human insulin is most popularly used. 2. Intensive insulin therapy: Intensified conventional insulin therapy, that is a multiple injection regimen and a twice a-day insulin regimen using a mixture of intermediate- and short-acting insulins has been commonly accepted. New devices such as pen-type injectors and jet-injectors have also been introduced for simplifying the multiple injection regimen. Continuous subcutaneous insulin injection (CSII) has also been adopted by adolescents and young adults.

Abstract
Administration of insulin with premeal boluses of short-acting insulin using a new injection device (Novopen) was compared with a conventional three times daily injection regimen regarding aspects of quality of life and metabolic control in insulin-dependent diabetes mellitus (IDDM). Eighteen C-peptide-negative patients with IDDM (16 men, two women, aged 31.0 +/- 7.4 years, duration of diabetes 13.0 +/- 4.6 years; mean +/- SD) participated in the study. All patients had been treated with three daily insulin injections for at least 1 year prior to the study. The patients were randomized into two groups. Group A started a 3-month treatment period with premeal injections of short-acting insulin and intermediate-acting insulin at bedtime. This period was followed by another 3 months using the initial three times daily injection regimen. Group B completed the study in the reverse order. Quality of life was assessed by using questionnaires and personal interviews by the same clinical psychologist. Metabolic control was assessed by measuring the levels of glycosylated hemoglobin. The results show that both treatment groups experienced a general improvement in mood and well-being during the period with multiple insulin injection treatment. Furthermore, during the periods of insulin pen treatment, an increased experience of freedom and less dependence on fixed meal times were noted. Overall metabolic control, insulin dosage, body weight, and number of hypoglycemic episodes did not change during the study. It is concluded that metabolic control, safety, and number of hypoglycemic episodes using premeal doses of short-acting insulin using Novopen were not different from those seen during conventional treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Intensive therapy of Type I diabetes is a system of therapy in which the patient is the key partner in day-to-day management. A number of technical developments in the late 1970s led to the development of intensive therapy. Self-monitoring of blood glucose (SMBG) proved to be the major change agent that stimulated the revolution in diabetes management that is intensive therapy. One important event that stimulated widespread use of SMBG was the development of spring-loaded finger-pricking devices. The introduction of glycated hemoglobin measurements as an indicator of glycemic control over several weeks allowed quantitative assessment of glycemic control. The advent of continuous subcutaneous insulin infusion (CSII) stimulated thinking about insulin regimens. These advances have combined not only to facilitate development of intensive therapy as a strategy of diabetes management, but also to permit development of research protocols to assess the impact of such therapy on the chronic complications of diabetes.

Abstract
Insulin initially became available for therapy in the 1920s. Over the years, a variety of insulin preparations have been formulated; preparations differ on the basis of purity, species of origin, and time course of action. Currently, highly purified preparations of human insulin are available with a variety of profiles of action.

Abstract
A controlled trial of pen injection of insulin was performed in 78 patients, with assessment of metabolic control and lifestyle. After a 6-week run-in period, during which control was optimized, the patients were randomized, either to stay on a twice daily insulin regimen (n = 37), or to change to a three times daily pen regimen with human ultralente at night (n = 41). Over the 20 weeks, there was no significant change in mean glycosylated haemoglobin (syringe, mean +/- SD, 11.1 +/- 2.5% to 10.9 +/- 2.0%; pen, 11.3 +/- 2.6% to 11.2 +/- 2.0%), in blood glucose profiles or in frequency of hypoglycaemic attacks in either group. A self-completed questionnaire demonstrated high patient satisfaction with the pen injector (NovoPen), 78% for effect on lifestyle and 81% for increased flexibility. Ninety-five percent preferred the pen injector regimen to conventional treatment and stayed on it.

Abstract
Currently available treatment methods, albeit improved, remain less than totally satisfactory. New developments such as improved viability of whole organ pancreatic transplants, islet cell transplantation, immunosuppression in the treatment of new-onset diabetes, development of reliable glucose sensors to provide continuous feedback for insulin delivery devices, and alternate routes for insulin administration may drastically change diabetes treatment in the future. For now, physicians must carefully consider the risks and benefits associated with available treatments when discussing therapeutic options with patients and their families. The wide range of therapies available provides the opportunity for patient and physician to select the most appropriate treatment regimen.

Abstract
The acceptability and efficacy of injecting insulin through a subcutaneous FEP cannula (to reduce the frequency of needle pricks) compared with conventional multiple injection therapy was examined in a cross-over study. Thirty-two insulin-dependent diabetic patients injected through the cannula for 10 weeks using a pen injector, followed by 10 weeks using the injector alone, or vice versa. Rapid-acting insulin was given before meals and intermediate-acting insulin at bedtime. Blood glucose control was not affected by cannula use (glycosylated haemoglobin: cannula, 8.6 +/- 0.3%; no cannula, 8.6 +/- 0.3%). Twenty-two of the 30 patients completing the study preferred to use the cannula and 21 requested to continue using it. There were no complications associated with its use.

Abstract
The development of battery-powered pumps for continuous subcutaneous insulin infusion added new dimensions to control of diabetes during pregnancy. In this report, we describe our experiences with 28 pregnant diabetic women offered participation in an insulin pump program. Fifteen (54%) accepted pump therapy and ten continued usage during their pregnancies. Excluding abortions, eight women continuing pump use are compared to 11 others who declined such therapy and were treated with conventional methods. Although these two groups are small and not strictly comparable, the experiences now reported provide clinical insights into the application of this new technology during pregnancy. Women who successfully used insulin pumps were typically from the private sector and in better glucose control at study entry. The degree of control during pregnancy in women using pumps was not significantly different compared to conventional glucose control methods (mean glucose 120 mg/dl and 142 mg/dl, respectively). Similarly, several indices of pregnancy outcome including length of hospitalization, costs, and perinatal morbidity associated with diabetes were analyzed and no significant differences were observed. We conclude that insulin pumps are not acceptable to all pregnant diabetic women and that such therapy may not necessarily improve pregnancy outcome.

Abstract
Ten patients with poorly controlled type I diabetes mellitus and a documented complication of their disease were observed during 6 months of conventional diabetic management followed by 6 months of insulin infusion pump treatment and home blood glucose monitoring. Median nerve conduction velocity (NCV) was inversely correlated with the glycosylated hemoglobin (HbA1c) level at entry into the study (r = 0.71; P less than 0.05). The mean HbA1c value at the end of the conventional treatment period was 14.3% and fell to 10.1% by completion of the pump treatment period (P less than 0.0001). The median NCV was significantly greater at the completion of the infusion treatment period than it was at the end of the conventional management portion of the study. However, the rate of increase in NCV during the infusion period was not greater than the rate established during the prior treatment period. In addition, change in HbA1c levels during the pump treatment period did not correlate with change in conduction velocity for any of the nerves studies. These results from a self-controlled study of continuous subcutaneous insulin infusion indicate that improved blood glucose control without normalization of metabolic parameters is not sufficient to reverse the functional deterioration of large, fast-conducting nerve fibers that occurs in type I diabetes.

Abstract
Twelve C-peptide negative insulin-dependent diabetic patients participated in a randomized cross-over study of 6 months treatment with twice or thrice daily insulin injection therapy and continuous subcutaneous insulin infusion (CSII). Standard, non-intensified management conditions were maintained throughout. Glycosylated haemoglobin levels were similar on both regimens (9.2 +/- 0.5% versus 9.0 +/- 0.4%; CSII vs injection therapy; (mean +/- SEM). Capillary blood glucose concentrations before breakfast (5.2 +/- 0.4 mmol/l vs 9.1 +/- 0.8 mmol/l), after lunch (6.5 mmol/l +/- 0.8 vs 7.9 +/- 1.0 mmol/l) and before the evening meal (5.0 +/- 0.7 mmol/l vs 7.7 +/- 0.7 mmol/l) were lower on CSII, as were 24-hour urine glucose excretion and total insulin dose (39.3 +/- 2.2 vs 49.8 +/- 4.0 U/day). There was a significant positive correlation between fasting blood glucose values and glycosylated haemoglobin on injection but not pump treatment. Thus although blood glucose control at some individual daytime points appeared lower on CSII, overall diabetic control was similar on the two regimens.

Abstract
It has been questioned whether aiming at near-normoglycaemia by intensified insulin treatment regimens is feasible and safe for the majority of patients with insulin-dependent diabetes. In this study, intensified insulin injection therapy (including blood glucose self-monitoring and multiple insulin injections) based upon a 5-day inpatient group teaching programme was evaluated in Type 1 (insulin-dependent) diabetes mellitus in the centralised health care system of Bucharest. One hundred patients (group A, initial HbA1 12.5%) were followed for 1 year on their standard therapy (individual teaching, no metabolic self-monitoring), and thereafter for 1 year on intensified therapy. Another 100 patients (group B, HbA1 12.3%) were followed for 2 years on intensified therapy. A third 100 patients (group C, HbA1 11.7%) were assigned to a basic 4-day inpatient group teaching programme with conventional insulin therapy (including self-monitoring of glucosuria and acetonuria) and followed for 1 year. Mean HbA1 remained unchanged after standard treatment (group A: 12.8% at 12 months), but decreased during intensified therapy (group A: 10.1% at 24 months; group B: 9.3% at 12 months, 9.5% at 24 months; p less than 0.0001). In group C, no change was found compared to standard treatment (i.e. group A at 12 months). Incidence rates of ketoacidosis were 0.16 episodes per patient per year during standard treatment, 0.01 during intensified treatment (p less than 0.01) and 0.04 in group C (p less than 0.025). Hospitalisation rates were reduced by 60% during intensified therapy and by 40% in group C. Frequency of severe hypoglycaemia was not significantly different between the three treatment regimens. Thus, under the condition that insulin treatment is based upon a structured and comprehensive training of the patient, intensified insulin injection therapy performed as routine treatment of Type 1 diabetes significantly lowers HbA1 levels without increasing the risk of severe hypoglycaemia.

Abstract
Insulin requirements are known to increase during pregnancy, but it has not been reported whether this relates to prandial or basal requirements, or to a change in insulin pharmacokinetics. In nine unselected pregnant patients the pattern of this increase was that of a large increase in the total morning dose and a reduction in the evening dose of intermediate acting insulin, in order to maintain good control while avoiding nocturnal hypoglycaemia. 24 h metabolic profiles were carried out in these patients in the third trimester of pregnancy. Plasma free insulin profiles reflected the dosage patterns and there was no change in insulin metabolic clearance rate in pregnancy. Pregnant diabetic patients had a broad peak of free insulin concentration around lunchtime followed by a steady fall until next morning. Blood lactate and alanine were higher than normal and 3-hydroxybutyrate lower than is usually seen in non-pregnant diabetic patients. The observations suggest that there may be differential changes in insulin sensitivity in diabetic pregnancy between the fed and fasting states, and that the therapeutic response to this causes a measurable metabolic change.

Abstract
The author, who had been an unstable diabetic since 1948, has attempted to maintain normoglycaemia since January 1977 after developing retinopathy and painful peripheral neuropathy. After 40 months of intensified conventional therapy (ICT), blood glucose fell from 13.0 +/- 2.0 (mean +/- S.D.) to 8.6 +/- 1.5 mmol/l (p less than 0.001), but with 36% of blood glucose tests still exceeding 10.0 mmol/l. After 6 years of continuous subcutaneous insulin infusion (CSII) mean blood glucose was 6.6 +/- 0.7 mmol/l (p less than 0.001) CSII/ICT, with only 10% of tests exceeding 10 mmol/l, smoother glycaemic profiles and excellent control overnight with no hypoglycaemia. These improvements under CSII were attributed to continuous varied insulin intake, which was instantly and unobtrusively adjustable, and more reliable food/insulin/blood glucose relationships. No infusion-site abscesses or serious ketoacidosis developed. Under both therapies glycaemic control was readily disrupted by exercise, minor dietary inaccuracies, relaxing of vigilance and unknown factors. Whenever the sense of commitment faultered there was a tendency to maintain higher glycaemic values to avoid distressing hypoglycaemia. Over the nine years, retinopathy progressed, foot pains regressed slightly but no fresh complications developed. Thus, intensified conventional management alone improved control, but CSII enabled the author to remain near-normoglycaemic for years (given sufficient motivation), with a less regimented lifestyle.

Abstract
The essential components of an intensive insulin therapy program are maintenance of stable basal concentrations of insulin between meals and appropriate, timely increases in the concentration of circulating insulin after ingestion of meals. Closed-loop systems that both continuously monitor the plasma glucose concentration and continuously infuse insulin intravenously can reproducibly achieve near-normal glycemia in patients with insulin-dependent diabetes mellitus. Near-normal glycemia can also be achieved with use of a continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI) of regular insulin combined with a single injection of slowly absorbable insulin in properly selected, compliant and cooperative patients. The frequency of hypoglycemia is similar with CSII and MDI. The risks of catheter-associated problems and ketoacidosis, however, are greater with CSII than with MDI. In contrast, the basal concentration of insulin can be more reproducibly and rapidly regulated with CSII than with MDI. The ratio of risk versus benefit associated with intensive insulin therapy with either CSII or MDI is currently unknown.

Abstract
We studied median, ulnar and peroneal motor nerve conduction velocity (NCV) and median sensory action potential (SAP) latency and amplitude in 18 insulin-dependent diabetic patients who were begun on a continuous subcutaneous insulin infusion (CSII) program. With institution of this therapy, significant decreases in mean blood glucose and glycosylated hemoglobin occurred. After 12 months of CSII treatment, median, peroneal, and ulnar motor NCVs all increased significantly. The average NCV increase was 2.5 m/s. Median SAP amplitude and latency did not significantly change. In a second group of 12 diabetic patients with the same mean age and comparable initial NCV and SAP measures, no significant changes in motor NCVs or SAPs occurred after 12 months of conventional insulin treatment. These results indicated the need for further long-term studies of the role of strict glucose control in the prevention of diabetic neuropathy.

Abstract
Six normal subjects received subcutaneous human, porcine, and bovine ultralente insulin (0.30 U/kg) and diluent (control) in randomized order. Plasma glucose, C-peptide, and insulin were measured for 32 h after injection. From 10 h onward human ultralente produced significantly lower plasma glucose levels (p less than 0.05-0.01) compared to bovine ultralente. Porcine ultralente produced an intermediate hypoglycaemic response up to 16 h and was similar to the bovine insulin from 24-32 h. Estimated exogenous insulin concentration was higher (p less than 0.05-0.001) following human ultralente compared to bovine ultralente between 2 and 22 h after injection. Up to 24 h the porcine preparation led to intermediate insulin levels, but becoming identical to bovine ultralente from 28-32 h. Peak mean exogenous insulin values for human, porcine, and bovine ultralente were 0.054, 0.044, and 0.023 nmol/l at 14, 16, and 18 h, respectively, reaching 0.022, 0.013, and 0.013 nmol/l at 32 h. The different pharmacokinetic behaviour of human and bovine ultralente insulin must be considered when initiating treatment with human ultralente or transferring patients from bovine to human ultralente.

Abstract
The benefits of self-monitoring of blood glucose (SMBG) were assessed in 38 Chinese adults on conventional insulin regimens who had been performing SMBG for a mean duration of 26 months (range 15-40). For analysis patients were divided into 2 groups. Group A consisted of 27 insulin-requiring patients who were referred for SMBG because of poor control or young age (less than or equal to 35 years). Group B consisted of 11 IDDM patients who were on SMBG from diagnosis. Mean age and duration of SMBG were similar in the 2 groups though group A had longer duration of disease. In group A, mean haemoglobin A1 (HbA1) decreased from 12.4 +/- 0.5% before SMBG to 10.9 +/- 0.5% at 6 months (P less than 0.005), 10.7 +/- 0.5% at 12 months (P less than 0.005) and 10.3 +/- 0.4% after long-term SMBG. This was accompanied by a significant reduction in insulin requirement from 0.82 +/- 0.07 U/kg/day to 0.72 +/- 0.07 U/kg/day (P less than 0.05). In group B, insulin requirement progressively decreased in the first 6 months. At 12 months, mean HbA1 was 9.0 +/- 0.5% and insulin requirement was 0.58 +/- 0.08 U/kg/day. No significant change in HbA1 or insulin requirement was observed beyond the first year. After long-term SMBG, 82% of patients in group B had good control (HbA1 less than or equal to 10%) compared to 45% only in group A (P less than 0.05). Long-term SMBG is associated with sustained improvement in diabetic control and is particularly beneficial if introduced to diabetic patients right from diagnosis.

Abstract
An insulin injection device, NovoPen, incorporating cartridged U100 Human Actrapid insulin was used in a group of 31 insulin-dependent diabetic patients aged 31.4 +/- 11.2 years (mean +/- S.D.; range 16.5-57.0) to assess its acceptance and suitability in a regimen involving an injection before each of their three main meals plus an evening injection of Human Monotard insulin from a conventional syringe. Twenty-seven patients completed 48 weeks of NovoPen therapy and preferred to continue with the multiple injection regimen in the long term. The device was well accepted and may make multiple injection regimens more feasible.

Abstract
Twelve C-peptide deficient Type 1 (insulin-dependent) diabetic patients with abnormal peripheral nerve function were randomly assigned to continuation of conventional insulin therapy (CIT) or to continuous subcutaneous insulin infusion (CSII). There were no statistically significant differences at entry to the study between the two treatment groups in nerve function assessed by neurologic disability score, computer assisted sensation examination and measurements of amplitudes, distal latencies, F-wave latencies and somatosensory evoked potential latencies over the spine and conduction velocities of motor and sensory fibers of ulnar, median, peroneal, tibial, plantar and sural nerves. In addition, mean plasma glucose from 24 h profiles (12.5 vs 10.6 mmol/l, respectively) and HbA1 (11.0 vs 11.6%, respectively) did not differ significantly between the two treatment groups at entry. Despite improved glycaemia from CSII in 5 patients (one dropped out of the study after 2 months) contrasted to CIT in 6 patients (5.3 vs 9.9 mmol/l, respectively, p = 0.002) and HbA1 (8.5 vs 10.7%, respectively, p = 0.002), there were no significant differences in measurements of peripheral nerve function after 4 months. After 8 months of improved glycaemia (4.4 vs 10.2 mmol/l, p = 0.004) and improved HbA1 (8.3 vs 10.5%, p = 0.002), nerve conduction (p = 0.03) and vibratory sensation threshold (p = 0.002) were significantly better in patients treated with CSII than those who received CIT. The improvements in nerve function, although small, provide further evidence that some clinical endpoints of neuropathy are favorably influenced by improved control of glycaemia.

Abstract
Type I insulin-dependent diabetic patients have an increased risk of atherosclerotic vascular disease that may be determined in part by their tendency to develop circulating lipid and lipoprotein abnormalities. The occurrence of such findings in asymptomatic ambulant Type I patients with mild or moderate hyperglycemia might suggest that conventional methods of insulin treatment are as inefficient at normalizing lipid abnormalities as they are in achieving euglycemia. It would then be important to ascertain whether intensive methods of insulin treatment effectively normalized lipid levels. Ten insulin-dependent young adult diabetic patients were studied on a conventional insulin treatment regimen and then at two-monthly intervals for a six-month period during which they were managed by three different intensified insulin treatment regimens. Plasma glucose levels improved substantially (p less than 0.001) after two months of intensified therapy (106 +/- 4 mg/dl) and did not change significantly thereafter for the remaining four months of intensified insulin treatment. Apart from a short-lived decrease in total-, LDL- and HDL-cholesterol after two months of intensified treatment (baseline total triglyceride 116 +/- 13 mg/dl, total cholesterol 174 +/- 16 mg/dl, HDL-cholesterol 46 +/- 3 mg/dl). There were no persistent changes in serum lipids, lipoprotein cholesterol or in levels of their major apoproteins A-I, A-II and B. These findings support the contention that, despite moderate hyperglycemia, conventional insulin treatment may be adequate to maintain normal lipid levels. In such circumstances achievement of euglycemia by intensified insulin therapy leads to little change in circulating lipid and lipoprotein values.

Abstract
Defective recovery from insulin-induced hypoglycemia, due to combined deficiencies of glucagon and epinephrine secretory responses to plasma glucose decrements, occurs in some patients with insulin-dependent diabetes mellitus (IDDM). Patients with IDDM determined to have inadequate glucose counterregulation during an insulin infusion test (40 mU X kg-1 X h-1) with bedside plasma glucose monitoring and clinical observation have been found to have a 25-fold greater risk of severe hypoglycemia during subsequent intensive therapy than patients with adequate glucose counterregulation. Thus, the efficacy of the glucose counterregulatory systems determines the limits of intensive therapy of IDDM.
