Injection related anxiety in insulin-treated diabetes.

The presence of injection related anxiety and phobia may influence compliance, glycaemic control and quality of life in patients with insulin-treated diabetes. Unselected consecutive, insulin-treated patients attending a diabetes clinic for follow-up, completed a standardised questionnaire providing an injection anxiety score (IAS) and general anxiety score (GAS). A total of 115 insulin-treated (80 Type 1 and 35 Type 2) diabetic patients completed the questionnaire. Injections had been avoided secondary to anxiety in 14% of cases and 42% expressed concern at having to inject more frequently. An IAS > or = 3 was seen in 28% of patients and of these, 66% injected insulin one to two times/day, 45% had avoided injections, and 70% would be bothered by more frequent injections. A significant correlation between IAS and GAS was seen (Kendall's tau-a 0.30, 95% CI 0.19-0.41, P < 0.001). GAS was significantly associated with both previous injection avoidance and expressed concern at increased injection frequency. No significant correlation was seen with HbA1c and injection or general anxiety scores. Symptoms relating to insulin injection anxiety and phobia have a high prevalence in an unselected group of diabetic patients requiring insulin injections and are associated with higher levels of general anxiety.

Metformin-associated lactic acidosis: a rare or very rare clinical entity?

AIMS: Lactic acidosis is a well recognized complication of biguanide therapy which is potentially serious. Although the prevalence of metformin-associated lactic acidosis (MALA) is much lower than that associated with phenformin, it is still being reported sporadically which raises concerns for the practising clinicians. We review the currently available world-wide data of the prevalence of MALA, the risk factors for its development and the current practical guidelines on the use of metformin to minimize the risk of this potential hazard. METHODS: An extensive literature search was conducted from both Medline and Ovid (1965-98) using the following keywords: 'Type 2 diabetes mellitus', 'oral hypoglycaemic drugs', 'biguanides', 'metformin-associated lactic acidosis' and 'renal impairment'. RESULTS: MALA was found to be a very rare clinical entity, being 20 times less common than phenformin-associated lactic acidosis. Amongst all the risk factors, renal impairment appears to be the major precipitating factor for the development of MALA in metformin-treated patients. We also found cases of MALA where no precipitating factors were identified and the underlying mechanism in these cases remains unclear. Practical recommendations of metformin use to minimize the risk of MALA have been listed based on previous reports. CONCLUSIONS: The low prevalence of MALA is comparable to the prevalence of sulphonylurea-induced hypoglycaemia. Metformin has many beneficial metabolic effects in the management of Type 2 diabetes mellitus. Provided that the recommended guidelines for metformin use are strictly adhered to, its widespread use would be safe and the incidence of MALA will be further reduced.

Patterns of contraception in UK women with Type 1 diabetes mellitus: a GP database study.

AIM: To establish the patterns of contraceptive prescribing for women aged 15-49 with Type 1 diabetes mellitus (DM) and compare them with the patterns in women without diabetes. METHODS: This was a cross-sectional study using a UK primary care database. RESULTS: Nine hundred and thirty-eight women with a diagnosis of Type 1 DM were identified. A comparison group of women aged 15-49 without diabetes (n = 10000) were randomly selected from the database. Twenty-five per cent of the women with diabetes and 32% without diabetes were prescribed a hormonal contraceptive in 1994. Women with Type 1 DM were more likely to be prescribed a combined oral contraceptive than a progestogen only pill (POP) but were 2.12 (95% CI 1.65-2.72) times more likely to be prescribed a POP than women without diabetes and were less likely to be prescribed a combined pill - odds ratio 0.53 (95% CI 0.44-0.64). The pregnancy rate in women with Type 1 DM over the age of 25 years was lower than for women without diabetes. Women under 25 years with Type 1 DM seemed more likely to record a pregnancy. CONCLUSIONS: Differences between women with Type 1 DM and those without diabetes highlight the variation in the way that GPs and patients evaluate the risks and benefits when deciding on contraception.

Aldosterone excess: a rare non-nephrophathic cause of hypertension in type I diabetes.

The aetiology of hypertension in type 1 diabetes is commonly due to the presence of diabetic nephrology. A rare case of hypertension in a patient with type 1 diabetes and no proteinuria is reported, where the investigation of borderline hypokalaemia allowed us to make a diagnosis of hyperaldosteronism due to bilateral adrenocortical hyperplasia. Secondary causes of hypertension should always be considered in all diabetic patients, particularly in the absence of clinical proteinuria.

Cardiovascular outcomes in type 2 diabetes. A double-blind placebo-controlled study of bezafibrate: the St. Mary's, Ealing, Northwick Park Diabetes Cardiovascular Disease Prevention (SENDCAP) Study.

OBJECTIVE: To determine whether serum lipid intervention, in addition to conventional diabetes treatment, could alter cardiovascular outcomes in type 2 diabetes. RESEARCH DESIGN AND METHODS: There were 164 type 2 diabetic subjects (117 men, 47 women) without a history of clinical cardiovascular disease randomized to receive either bezafibrate or placebo daily on a double-blind basis in addition to routine diabetes treatment and followed prospectively for a minimum of 3 years. Serial biochemical and noninvasive vascular assessments, carotid and femoral artery B-mode ultrasound measurements, and those pertaining to coronary heart disease (CHD)--clinical history, the World Health Organization (WHO) cardiovascular questionnaire, and resting and exercise electrocardiogram (ECG)--were recorded. RESULTS: Bezafibrate treatment was associated with significantly greater reductions over 3 years in median serum triglyceride (-32 vs. 4%, P = 0.001), total cholesterol (-7 vs. -0.3%, P = 0.004), and total-to-HDL cholesterol ratio (-12 vs. -0.0%, P = 0.001), and an increase in HDL cholesterol (6 vs. -2%, P = 0.02) as compared with placebo. There was a trend toward a greater reduction of fibrinogen (-18 vs. -6%, P = 0.08) at 3 years. No significant differences between the two groups were found in the progress of ultrasonically measured arterial disease. In those treated with bezafibrate, there was a significant reduction (P = 0.01, log-rank test) in the combined incidence of Minnesota-coded probable ischemic change on the resting ECG and of documented myocardial infarction. CONCLUSIONS: Improving dyslipidemia in type 2 diabetic subjects had no effect on the progress of ultrasonically measured arterial disease, although the lower rate of "definite CHD events" in the treated group suggests that this might result in a reduction in the incidence of coronary heart disease.

Needle phobia in type 1 diabetes mellitus.

Needle phobia in patients with Type 1 (insulin-dependent) diabetes mellitus is difficult to manage. We report a case of long-standing needle phobia in a patient with 33 years of Type 1 diabetes mellitus who has developed very few vascular complications. Further studies are required to identify the prevalence of needle phobia in Type 1 diabetes mellitus. Once these individuals have been identified, appropriate psychological and physical treatments should be implemented, in the hope of making such individuals less fearful of the treatment of their condition.
