Hydrocephalus, mineralizing angiopathy, hypercholesterolemia, and hyperlipoprotein (a).
ABSTRACT A boy born at 34 weeks gestation with initially normal development presented with acute hydrocephalus at 22 months. Subsequently his development has been slow and complicated clinically by epilepsy. Upon extensive investigation, he has been found to have extremely elevated lipoprotein(a) levels, hypercholesterolemia (familial), and lesions of the cortex and meninges. Radiologic studies have disclosed a mineralizing angiopathy.

ABSTRACT: Diabetic patients are at increased risk of cardiovascular disease, particularly when proteinuria is present. Lipoprotein(a)[Lp(a)] levels were assessed in 37 patients with insulin dependent (IDDM) and in 75 patients with non-insulin dependent (NIDDM) diabetes who showed varying degrees of proteinuria and glycaemic control. Median Lp(a) in 112 diabetic patients was significantly greater than in 116 healthy controls (113 vs 48 mg/L; p less than 0.01). 86 of the patients had first morning urine albumin concentration less than 30 mg/L (normoalbuminuria = NA), 16 patients 30-200 mg/L (microalbuminuria = MA) and ten patients greater than 200 mg/L (albuminuria = ALB). There was no significant difference in median Lp(a) concentration between the three groups (NA = 108, MA = 163, ALB = 98 mg/L; p greater than 0.5). No significant difference in median Lp(a) or NIDDM treated with oral agents and/or diet (120, 98, 115 mg/L respectively; p greater than 0.7). When the 86 NA patients were divided on the basis of median fructosamine concentration (357 mumol/L), no significant difference was found in median Lp(a) levels between those grouped below or above this median (98 mg/L vs 118 mg/L; p greater than 0.5). Across all diabetics studied there was no significant correlation present between Lp(a) and urinary protein or glycaemic control. These cross-sectional results suggest that median Lp(a) concentration is increased in both IDDM and NIDDM patients, but this increase is not related to the degree of proteinuria or short-term glycaemic control.Australian and New Zealand journal of medicine 09/1992; 22(4):329-33.

ABSTRACT: Lipoprotein(a) [Lp(a)], which combines structural elements of the lipid and fibrinolytic systems, is a major independent risk factor for the development of coronary heart disease. Eighty-four consecutive patients with peripheral vascular disease (of whom 42 had concomitant ischaemic heart disease) and 43 healthy controls were enrolled in a case-control study. We found that the mean Lp(a) concentration in male patients with peripheral vascular disease (PVD) was almost threefold higher than that of controls, while in female patients the Lp(a) concentration was more than twice that of controls. This marked difference was borne out in patients with and without concomitant ischaemic heart disease (IHD). A multivariate logistic regression analysis indicated that Lp(a) is independently associated with PVD when adjusted for age and sex (odds ratio per 100 mg l-1 increase in Lp(a) = 1.35; P < 0.01). A similar association is observed for patients with concomitant IHD (odds ratio per 100 mg l-1 increase in Lp(a) = 1.65; P < 0.01).Journal of Internal Medicine 10/1992; 232(4):349-52. · 6.46 Impact Factor
