Control of blood pressure and other cardiovascular risk factors at different practice settings: outcomes of care provided to diabetic women compared to men.

Cardiovascular disease (CVD) is the major cause of morbidity and mortality in diabetes. To determine the proportion of patients who met the American Diabetes Association guidelines for control of CVD risk factors and to assess the achievement of these guidelines in women compared with men, we conducted a cross-sectional study of 3678 diabetic cohorts followed at seven medical centers, two Veteran Administration hospitals, three urban clinics, and two suburban clinics. Overall, 28% met the target blood pressure of <130/80 mm Hg, 48.8% achieved a goal low-density lipoprotein cholesterol of <100 mg/dL, and 35.8% had hemoglobin A1c of <7%. Gender comparisons of 2788 diabetic patients at urban and suburban centers showed that women had a lower percentage of low-density lipoprotein cholesterol <100 mg/dL (45.8 vs. 51.3, p<0.01) and a lower percentage of screening for retinopathy (54 vs. 60, p<0.01) and nephropathy (37 vs. 49, p<0.01). However, overall there were no gender differences in the percentage of patients who achieved a goal blood pressure <130/80 mm Hg or hemoglobin A1c <7%. Control of blood pressure and other CVD risk factors in diabetic patients was largely suboptimal, especially for diabetic women. These observations underscore the need for better strategies for control of CVD risk in the diabetic population in general, and women in particular.

ImmunoDip: an improved screening method for microalbuminuria.

BACKGROUND: It is important to test for microalbuminuria in patients with diabetes, hypertension and possible insulin resistance syndrome. Current screening methods are suboptimal. This study evaluates a new office screening test for microalbuminuria that utilizes a monoclonal antibody against human serum albumin (ImmunoDip). METHODS: 182 urine samples were collected from patients attending diabetes, nephrology or hypertension clinics. The ImmunoDip screening test was carried out in the 182 samples after which albumin and creatinine concentrations were measured quantitatively in a reference laboratory. RESULTS: Screening the 182 patient samples with ImmunoDip and designating an albumin:creatinine ratio of > or =30 microg/mg as positive yielded a sensitivity of 96%, a specificity of 80%, a positive predictive value (PPV) of 66% and a negative predictive value (NPV) of 98%. The reduced specificity and PPV were not due to an intrinsic inaccuracy with ImmunoDip screening of these samples, but rather was shown to be due to the discordance between the accepted upper limits of normal for the albumin:creatinine ratio (30 microg/mg) and the albumin concentration (20 mg/l), the latter corresponding to a ratio of 20 microg/mg. In 35 samples with albumin concentrations of 20-50 mg/l, ImmunoDip screening yielded only one false negative (FN) result. CONCLUSIONS: ImmunoDip is an excellent screening tool for microalbuminuria.

Blood pressure control and nephroprotection in diabetes.

Achievement of recommended levels of blood pressure as prescribed by guidelines (i.e., systolic blood pressure of < 130 mmHg in people with nephropathy secondary to type 2 diabetes) generally requires three or more different antihypertensive agents that have complementary modes of action. This systolic goal blood pressure, recommended by generally all international guideline committees, was derived from largely observational studies demonstrating a greater reduction of cardiovascular risk and preservation of kidney function at these levels. Commonly used antihypertensive combinations include angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers, which have compelling indications for use in people with kidney disease and/or diabetes, combined with a diuretic, generally a thiazide-type agent. If additional therapy is required, either a beta-blocker or a calcium antagonist may be added to this antihypertensive "cocktail." Beta-blockers are particularly effective in people with a high sympathetic drive (i.e., high pulse rates) to lower blood pressure and reduce cardiovascular risk. Moreover, in recent studies, their benefits on kidney function, both by reducing macroalbuminuria and slowing the decline of kidney function, make them good agents to add in the appropriate clinical setting. With all these potential benefits of achieving blood pressure goals, it is unfortunate that only 11% of people being treated for hypertension with diabetic kidney disease achieve the blood pressure goal of < 130 mmHg, likely contributing to the climbing incidence of people starting dialysis. Physicians need to work harder and educate patients on the importance of achieving these lower blood pressure guidelines.
