Hyperlipidaemia is a characteristic feature not only of the nephrotic syndrome but also of chronic renal disease without the features of that syndrome. There is evidence for disordered lipid metabolism in patients with chronic renal disease. In these patients the disordered lipid metabolism, the precise cause of which is unknown, is characterised by hypertriglyceridaemia, the aetiology of which is probably multifactorial. Hyperlipidaemia is an important potential risk factor in the aetiology of cardiovascular disease, which may be a leading cause of death in patients undergoing long-term maintenance haemodialysis therapy.

Both naturally occurring disease processes and experimental models of human disease in the Mongolian gerbil were reviewed. The gerbil was highly susceptible to cerebral infarction following unilateral ligation of one common carotid artery and was useful in studies of the pathogenesis of stroke. Spontaneous epileptiform seizures mimicked those of human idiopathic epilepsy, and both seizure-sensitive and resistant strains have been bred. Perhaps because of its more efficient nephron, the gerbil accumulated four to six times as much renal lead as the rat, and the gerbil has been proposed as an experimental model of lead nephropathy. On standard diets, about 10% of the animals became obese, and some showed decreased glucose tolerance, elevated serum immunoreactive insulin and diabetic changes in the pancreas and other organs. Some breeders exhibited hyperactivity of the adrenal cortex associated with hyperglycemia, hyperlipidemia and degenerative vascular disease. Although dietary supplements of cholesterol were toxic and did not induce atherosclerosis, the gerbil was useful in other studies of cholesterol absorption and metabolism. Spontaneous, insidious periodontal disease became evident after about 6 months on standard diets, and dental caries were induced by cariogenic diets or by pathodontic streptococci. Spontaneous neoplasia occurred in 8.4--24% of gerbils, usually after 2 years of life. Adrenal cortical, ovarian and cutaneous tumors were the most consistently reported neoplasms.

The female patient initially showed the acquired type of total lipoatrophy at about 8 years of age. At 12 years of age, the onset of diabetes mellitus was speculated from advanced pyodermia and dedentition. At 29 years of age, glucosuria was found, and she developed proteinuria, ascites, and pretibial edema. The physical examination revealed: hepatosplenomegaly, complete absence of subcutanous fat, cutaneous xanthomas, and emaciated facies with pronounced zygomatic arches. Diabetic retinopathy was revealed in the ophthalmological examination, and nephropathy was evident in renal biopsy specimens. She also had peripheral diabetic neuropathy. No adipose tissue was found in the mesenterium under peritoneoscopy. The hepatic biopsy specimen revealed advanced portal liver cirrhosis. Laboratory findings included: hyperlipidemia, elevation of BMR without evidence of hyperthyroidism, impaired renal function, and undetected anti-insulin antibodies and anti-insulin antibodies. Endocrinological examinations revealed normal value, except for an impaired hGH response in the arginine test. C-peptide immunoreactivity was high. Her condition was fairly well controlled by 140 units of insulin injection daily.

Hemodialysis and hyperlipidemia have been associated in both adults and children. The present study indicates hyperlipidemia in uremic children treated with peritoneal dialysis and implies that the cardiovascular risk felt to exist with hemodialysis also exists in peritoneal dialysis. Thirty-eight children with chronic renal insufficiency or end-stage renal disease were followed serially under varying conditions of medical management, hemodialysis, peritoneal dialysis, and transplantation. Serum triglyceride concentrations in patients on peritoneal dialysis were not significantly different from those in patients on hemodialysis, but both were significantly higher (P less than 0.01) than concentrations in patients on medical management and transplantation.

Using clearances of microaggregated iodinated human serum albumin in a serial 'stress test,' defective phagocytosis by the Kupffer cells has been demonstrated in diabetic patients with K.W. nephropathy and proliferative retinopathy. This indicates a disturbance of phagocytic cell function that has implications for the cellular pathology of microangiopathy. The effect is not due to uremia, but could be due to T3 deficiency or lipid deposition. In hypothyroidism, there is defective RES phagocytosis, and alcoholics with hyperlipidemia can have impaired clearances. Hence, patients with advanced diabetes, hypothyroidism, and some alcoholics are at risk from infection.

Many alterations in metabolic and endocrine function occur in end-stage renal disease. Glucose intolerance is almost always present with uremia; it improves shortly after institution of regular hemodialysis. Hyperlipidemia (type IV) is prevalent, and atherosclerotic cardiovascular disease causes death in about 50% of patients receiving long-term hemodialysis. Although plasma levels of growth hormone usually are elevated, children with chronic renal failure show growth retardation. The occurrence of thyroid disorders is difficult to determine, since many clinical features of uremia are similar to those of hyperthyroidism and hypothyroidism. The incidence of duodenal ulcer is high, possibly due to high gastrin levels. Sex hormone disturbances are common. Anemia is a constant feature of chronic renal failure; patients usually tolerate it well.

Fasting serum triglyceride and cholesterol measurements, and lipoprotein characterization by ultracentrifugation, were performed in four groups of patients with chronic renal disease (uraemic, short- and long-term haemodialysis and renal transplant recipients) and the results compared with those obtained from age- and sex-matched control subjects. Basal insulin and growth hormone levels, and serum creatinine and albumin concentrations were measured in, and detailed dietary histories taken from patients in each group. The predominant lipid abnormalities were hypertriglyceridaemia and increased very low density lipoproteins (type IV hyperlipoproteinaemia) in both uraemic and haemodialysis patients. Following renal transplantation, a different pattern of hyperlipidaemia was found. Hypercholesterolaemia was more common and hypertriglyceridaemia less common than in the uraemic and haemodialysis group. The lipoprotein abnormalities were increased low density and/or very low density lipoproteins, with types IIa IIb and IV hyperlipoproteinaemia occurring equally frequently. In uraemic and haemodialysis patients, the proportion of carbohydrate in the diet was high, and may have played a role in the genesis of hypertriglyceridaemia. There was a positive correlation between relative body weight and serum triglyceride in the long-term dialysis group. In renal allograft recipients hypertriglyceridaemia could be attributed, at least in part, to obesity, prednisone dosage and the degree of impairment of graft function. The aetiology of hypercholesterolaemia in the transplant recipients was unclear. Neither basal insulin nor growth hormone levels were elevated in any patient group. Uraemic hypertriglyceridaemia is a clearly defined and well documented metabolic abnormality which is not corrected by dialysis. Post-transplantation hyperlipidaemia however, is a condition of variable presentation and multifactorial aetiology.

One hundred and ten patients with radiologically established peripheral atherosclerotic arterial disease were studied. None of them suffered from diabetes, endocrine disorders or renal disease. Their serum cholesterol and triglyceride values were compared with those of a reference group consisting of 548 individuals. When the 95th percentile of the reference values was used for cut-off, the frequency of hyperlipidemias in the patients with peripheral arterial atherosclerosis was about 52%. Combined hyperlipidemia was slightly more common (21%) than isolated increase of either cholesterol (17.9%) or triglycerides (12.6%). Using other cut-off limits for the definition of hyperlipidemia, a striking change in the distribution between these three types of hyperlipidemia occurred. In our patients, the frequencies of different blood groups were not significantly different from those of a comparable population. The serum lipids were at the same level in the different blood groups.

A familial syndrome of partial lipodystrophy inherited as a dominant trait is reported. Subcutaneous fat loss was confined to the extremities and trunk. Diabetes mellitus, hyperlipidemia, hepatomegaly and renal disease were very prevalent in this family. Metabolic studies were performed on 3 members. In vivo tests suggested that the remaining fat tissue responded normally to stimulators and inhibitors of lipolysis. In vitro incubation of the dystrophic fat tissue of one patient suggested that the intracellular pathways of lipid and glucose metabolism were normal. The pattern of subcutaneous loss of adipose tissue observed in this family may be due to sympathetic nervous system overactivity of certain non-contiguous dermatomes.

The prevalence of coronary heart disease (58%) in 43 patients with analgesic nephropathy with moderate to severe chronic renal failure was significantly higher than in the general population of the same age and sex. Mean serum triglyceride concentration and mean diastolic blood pressure were significantly higher in the group with coronary heart disease (214 mg/dl and 102 mm Hg, respectively) than in the group without it (162 and 94). Serum triglyceride values correlated inversely with GFR, indicating that hypertriglyceridemia was largely due to associated chronic renal failure; a specific effect of analgesic abuse on prevalence of heart disease, noted by others, could not be assessed in the absence of GFR-matched controls. The prevalence of coronary heart disease was significantly higher (81%) in the group with combined hyperlipidemia (hypertriglyceridemia and hypercholesteremia) compared to the groups without it or with normal serum triglyceride concentrations (44 and 41%, respectively). Hypotryptophanemia (a possible cause of hyperlipidemia in the nephrotic syndrome) was present in 77% of patients.
