Technetium 99mTc-DTPA clearance in the evaluation of pulmonary involvement in patients with diabetes mellitus.

Systemic thickening of capillary endothelial basement membrane underlies the chronic complications of human diabetic microangiopathy. Since 99mTc-DTPA aerosol scintigraphy is a sensitive, non-invasive test of membrane permeability, we decided to study the effect of diabetes on the permeability of lung epithelium in diabetic patients using this test. Fifty (NIDDM) patients, aged 40-70 years, with or without complications, and who were non-smokers, were subjected to evaluation using 99mTc-DTPA aerosol.

The association of skin test reactivity, total serum IgE levels, and peripheral blood eosinophilia with asthma in Kuwait.

There is evidence that elevated serum immunoglobulin E (IgE) and eosinophilia correlate well with allergic skin test reactivity. These parameters have been used as alternative methods to characterize atopic subjects. Skin test reactivity is the only measure used routinely in clinical practice in Kuwait to reflect atopy in asthma patients.
