Prevalence of haemoglobin variants in a diabetic population and their effect on glycated haemoglobin measurement.

The measurement of glycated haemoglobin (glycated Hb) by automated high pressure liquid chromatography enabled the prevalence of haemoglobin variants (Hb variant) to be determined in a large diabetic population within Leeds, UK. There were 16 patients showing a Hb variant amongst a total of 5300 diabetics, the majority of the variants being HbA/S traits. There were also 13 patients showing a slightly raised HbF in the range of 2% to 5%. A multi-centre study was carried out by distributing blood specimens from some of the patients with Hb traits. Significant differences in the percentage of glycated Hb were observed relating to the methodology used. However, glycated Hb is used to monitor glycaemic control and laboratories must be aware of Hb variant interferences on their methods. Also, screening for Hb variants should be considered for the at risk groups of diabetic patients.

The use of alternative therapies by Auckland general practitioners.

A survey of Auckland general practitioners was undertaken to explore their use of, and attitudes to, alternative medicines. Three hundred and seventy randomly selected doctors, from a total of about 700 doctors practising in Auckland, were posted questionnaires. Of 249 respondents, 75 (30%) practised one or more forms of alternative medicine. Acupuncture was the therapy most commonly used. Musculoskeletal disorders and chronic pain syndromes were the most frequently treated conditions. A total of 171 (68.7%) respondents referred patients to one or more forms of alternative treatment, and only 56 (32.7%) of these felt it necessary that the person referred to be medically qualified. Younger doctors were more inclined to refer and the most commonly cited reason for referral was failure of conventional medicine.

Prevention of deterioration of renal and sensory-nerve function by more intensive management of insulin-dependent diabetic patients. A two-year randomised prospective study.

74 insulin-dependent diabetic patients with background retinopathy were randomised to continue with usual diabetic care (group U) or to a more intensive programme (group A) using ultralente insulin as basal cover and soluble insulin at mealtimes. Group A attended the clinic more frequently, received closer dietary supervision, and were taught home blood glucose monitoring. Group A had a significantly lower mean glycosylated haemoglobin level during the study, although the mean level also fell in group U towards the end of year 2. Renal and sensory-nerve function were significantly better preserved in group A than in group U. Significant improvements were also seen in low-density-lipoprotein-cholesterol and whole-blood low-shear viscosity. The rate of progression of retinopathy was similar in both groups. It appears that a modest improvement in diabetic control, obtainable in most clinics, has been associated with a reduction in the progression of diabetic tissue damage.
