Relationship of muscle capillary basement membrane thickness and diabetic retinopathy. 1987

We examined the relationship between the thickness of the quadriceps muscle capillary basement membrane and diabetic retinopathy. Basement membrane thickness was measured in two groups of patients with long-standing type II diabetes mellitus. One group of patients (N = 13) had no evidence of diabetic retinopathy on fluorescein angiography, whereas the other (N = 12) had proliferative microvascular disease. All the patients were male, and both groups were of similar ages, duration of diabetes, serum creatinines, and glycemic control as reflected by HbA1 levels. Mean muscle capillary basement membrane width (+/- SE) of the patients with proliferative retinopathy (3346 +/- 262) was significantly greater (P less than .05) than that observed in the patients without retinopathy (2660 +/- 177). The results of this study suggest that there is a relationship between capillary basement membrane thickness in skeletal muscle and the severity of microangiopathy in the eye. However, there was a substantial overlap between the two groups, indicating that for any individual patient the measurement of muscle capillary basement width will probably not be useful in identifying the presence or absence of retinopathy.

D003924 Diabetes Mellitus, Type 2 A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

D003930 Diabetic Retinopathy Disease of the RETINA as a complication of DIABETES MELLITUS.

D001485 Basement Membrane A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue. BM, composed mainly of TYPE IV COLLAGEN; glycoprotein LAMININ; and PROTEOGLYCAN, provides barriers as well as channels between interacting cell layers.
