Ocular signs and symptoms provide clinical clues to many of the more common metabolic and nutritional disorders seen in older adults. Diabetes mellitus can affect all parts of the eye and orbit. Complications include refractive visual loss, macular edema, retinopathy, increased risk of fungal infection, and diplopia. In patients with gout, urate crystals may precipitate in the eye and cause conjunctivitis, uveitis, or scleritis. Other problems are seen with Wilson's disease, hyperlipidemia, and albinism. Nutritional disorders usually arise from malabsorption, gastrointestinal surgery, and alcohol abuse. Deficiencies in vitamins A, B1 (thiamine), B12, and C may be manifest in the eye.

The association between serum uric acid concentration and some cardiovascular risk factors was examined in a working Hong Kong Chinese population (mean age 38 years), consisting of 910 men and 603 women. There was no significant age-related rise in serum uric acid concentration. Positive associations were found between serum uric acid concentration and body mass index, waist hip ratio, systolic and diastolic blood pressure, urea, creatinine, protein, glucose (fasting and 2 hours after 75 g oral glucose load), 2 hour insulin, triglycerides, and apolipoprotein B in men. Similar, but fewer, associations were seen in women, with the addition of a positive association with age. In both sexes, serum uric acid was negatively associated with high-density lipoprotein cholesterol. These findings complement the well-known clinical association between gout and cardiovascular and metabolic diseases, such as hypertension, hyperlipidaemia and diabetes mellitus, and suggest that serum uric acid may be a marker for the presence of an adverse cardiovascular risk factor profile.

To evaluate long-term benefits and risks of CyA therapy in renal transplantation, we analyzed the 10-year experience with all 59 patients who had received a first cadaveric renal graft until August 1983 and were immunosuppressed with CyA. We compared their actual graft survival with that of all 213 patients who had received a first cadaveric graft from 1967 until August 1983, but were immunosuppressed initially with azathioprine and prednisone (AzaP). For comparison of p-creatinine, proteinuria, blood pressure, lipids, uric acid and skin malignancies we evaluated the patients staying unchanged on initial therapy for 10 years (CyA = 12, AzaP = 53). RESULTS. (1) Actual graft survival at 10 years was 34% (20/59) with CyA and 27% (58/213) in AzaP treated patients (intention to treat) (P = .09 = ns). At 1 to 5 years, graft survival was 15% superior with CyA, but after 7 years the survival curve of the CyA-group has closely joined the chronic decline seen in the AzaP group. This behaviour could neither be explained by chronic CyA-nephrotoxicity nor by chronic rejection after switching from CyA to AzaP. (2) P-creatinine at 10 years was significantly (P < .03), but mildly elevated under CyA (130 +/- 52; AzaP = 109 +/- 65). (3) Proteinuria (g/d) at 10 years was not significantly different (CyA = 0.41 +/- 0.58, versus AzaP = 0.83 +/- 1.61). (4) Systolic blood pressure was higher at 10 years under CyA (152 +/- 19) than under AzaP (136 +/-) (P < .02), but diastolic pressure was not (89 +/- 10 versus 84 +/- 12; ns). Antihypertensive drug/patient was twice as high under CyA (1.25 versus 0.64 P < .02). (5) Cholesterol, triglyceride, HDL were not different. 75% of the CyA-patients were steroid free at 10 years, none of the AzaP-patients. (6) P-uric acid was not significantly different in both groups (494 +/- 192 vs 400 +/- 124), but 42% of CyA-patients were on uric acid lowering drug (given after at least one gout attack) as compared to 9% under AzaP (P < .006). (7) Seventeen percent of patients under CyA for 10 years had at least one skin cancer, not different from 15% of AzaP-patients. CONCLUSIONS. The main benefit of CyA was the better graft survival up to 5 years and the chance to stay free of steroids. The main risks of CyA were nephrotoxicity, hypertension and symptomatic hyperuricemia. No difference was found for hyperlipidemia and skin-malignancies.

Uric acid is formed by catabolism of purine nucleotides. Approximately 25% is excreted through the intestines and the rest through the kidneys. A little less than 5% of the population in western industrialised countries have hyperuricaemia, primarily men and postmenopausal women. Hyperuricaemia is in most cases caused by reduced renal excretion, which may be idiopathic with otherwise normal renal function. But the condition is often associated with hypertension, nephropathy and treatment with diuretics and certain other drugs. Hyperuricaemia due to increased purine metabolism is seen in malignant haematological diseases, other conditions with increased cellular turnover and during initiation of chemotherapy in malignant diseases. Moreover hyperuricaemia is associated with some metabolic disturbances and risk factors of atherosclerotic cardiovascular disease including hypertension, overweight, insulin resistance and hyperlipidaemia. Hyperuricaemia is rarely caused by constitutional enzymatic abnormalities influencing purine metabolism. In most cases hyperuricaemia is asymptomatic. It may though be complicated by gout, urolithiasis and possibly gouty nephropathy. The risk of complications is correlated to the degree and duration of hyperuricemia. Consequently, measures to affect predisposing and associated conditions should be taken including weight reduction, physical exercise and diet guidance, treatment of hypertension and possibly changes in medication. Urate lowering drug treatment is normally not indicated in asymptomatic hyperuricaemic individuals.

In order to identify previously undiagnosed cases of non-insulin dependent diabetes (NIDDM) in general practice, we measured non-fasting blood-glucose in all risk patients (n = 1,790) between 35-69 years old belonging to 29 general practices in Kolding. Patients at risk for NIDDM were defined as those suffering from one or more of the following: overweight, arterial hypertension, coronary heart disease, hyperlipidaemia, stroke, gout, cataract, Dupuytren's contracture, peripheral atherosclerosis or recurrent urinary- or skin-infections. A positive result, defined as a non-fasting blood-glucose of > or = 8.0 mmol/l using the same stix-lot-nr. on Refloflux S machines, was found in 86 individuals. These were then followed up with two fasting blood-glucose measurements carried out in a central laboratory, whereby 34 patients with NIDDM were identified. The newly-diagnosed NIDDM patients mostly suffered from diseases related to the insulin resistance syndrome, and we thus recommend measurement of non-fasting blood-glucose as a screening procedure in such patients. When carrying out measurements in general practice, it is important to know the precision and accuracy of the apparatus used.

Gout is a disease caused by deposits of sodium urate crystals in tissues. This disease, already known of Hippocrates, is now due to new causes, notably iatrogenic, and has new clinical forms. The typical initial attack usually occurs in men in their fifties and affects the big toe; in the absence of treatment it evolves towards chronic tophaceous gout. When gout occurs in subjects younger than 30 years, these must be investigated for enzyme deficit which is usually partial. The incidence of gout in women is ever increasing, being encouraged by treatments with diuretic drugs. Gout is often atypical, affecting predominantly the hands and with rapid development of tophus. In transplanted patients other drugs, such as cyclosporin, may induce an early, polyarticular and tophaceous gout. Alcohol is a facilitating factor of hyperuricaemia. Disturbances of metabolism, such as hyperlipidaemia, obesity or arterial hypertension, are often associated with hyperuricaemia. With an early and well-conducted treatment the passage to chronicity and the occurrence of complications can be avoided.

Conflicting data exist with respect to the existence and clinical manifestations of a hyperlipidemic arthropathy. Reasonable evidence supports the existence of a migratory polyarthritis similar to rheumatic fever in patients homozygous for type II hyperlipidemia. Although similar complaints have been described in patients heterozygous for this condition, findings have been inconsistent among various reports. It is possible that high lipid levels are required to induce rheumatic complaints, and these are found predominantly in homozygous patients. Even so, rheumatic syndromes appear to be more attributable to periarthritis because evidence of inflammatory arthritis is largely lacking. In contrast, Achilles tendinitis appears to be associated with heterozygous type II hyperlipidemia and presumably is based on lipid deposits within the tendon. Gout is an accepted association of type IV hyperlipidemia. In addition, oligoarticular symptoms have been described with type IV hyperlipidemia. However, no consistent clinical entity has emerged. Drugs used in the treatment of hyperlipidemia are associated with a variety of rheumatic problems, including proximal myopathy and lupus-like syndromes. The most commonly implicated drugs are the hydroxymethylglutaryl-coenzyme A reductase inhibitors and the fibric acid derivatives.

To clearly determine whether hyperuricemia participates directly in atherosclerotic disease or not, the prognosis and associated factors were studied, based on data from 104 patients whose serum uric acid had been completely maintained at normal levels with prolonged medication. The mean age at death was 65.8 +/- 10.5 years. The causes of death were as follows: cardiovascular disease (26.9%), cerebral disease (26.2%), malignant neoplasms (26.0%), uremia (7.6%), and miscellaneous disease (18.3%). Serum lipids especially triglycerides, body weight and influenced on the prognosis of the patients FBS. Most common complications were in the cardiovascular disease group; hypertension and hyperlipidemia. These data suggested that the apparent increased incidence of cardiovascular disease in gout rather than renal failure bore a relationship to such complications as hypertension or hypertriglycemia. Hyperuricemia alone may not be an atherosclerotic risk factors. There was no correlation between treatment with allopurinol and probenecid and cardiovascular complications.

High blood pressure (BP) in the elderly must not be ignored as a normal consequence of aging. The criteria for the diagnosis of hypertension and the necessity to treat it are the same in elderly and younger patients. The aim of treatment of elderly hypertensive patients is to decrease BP safely and to reduce risk factors associated with cerebrovascular, cardiovascular and renal morbidity and mortality. The treatment of elderly hypertensive patients should be adjusted according to the needs of the individual, based upon age, race, severity of hypertension, co-existing medical problems, other cardiovascular risk factors, target-organ damage, risk-benefit considerations and costs. In addition to the elevated BP, other cardiovascular risk factors include smoking, glucose intolerance, hyperinsulinaemia, dyslipidaemia, hypercreatininaemia, peripheral vascular disease, left ventricular hypertrophy, and microalbuminuria (or albuminuria). Thus, the choice of initial antihypertensive therapy in elderly hypertensive patients should be based not only on the expected response, but also on the effects of therapy on lipid, potassium, glucose and uric acid levels, and left ventricular anatomy and function. Co-existing medical conditions (such as asthma, diabetes mellitus, heart failure, renal failure, gout, coronary artery disease, hyperlipidaemia and peripheral vascular disease) are major determinants for the selection of antihypertensive medications. With previous therapies (diuretics, beta-blockers, etc.), good BP control in the elderly was associated with clear and statistically significant reductions in stroke-related morbidity and mortality, but the overall effects on cardiovascular and renal complications of hypertension was either more variable or less obvious. Angiotensin converting enzyme (ACE) inhibitors are not only efficacious antihypertensive agents in the elderly, but also appear promising in counteracting some of the cardiovascular and renal consequences of hypertension. They are well tolerated and have a relatively low incidence of adverse effects. ACE inhibitors possess ancillary characteristics that are potentially beneficial for many elderly patients, including reduction of left ventricular mass, lack of metabolic and lipid disturbances, no adverse CNS effects, no risk of induction of heart failure, and a low risk of orthostatic hypotension. Since ACE inhibitors may improve perfusion to the heart, kidney and brain, they are well worth considering for the treatment of elderly patients with hypertensive target organ damage, especially in patients with heart failure, and diabetic patients with early nephropathy.

Diabetic nephropathy can be regarded mainly as a type of microangiopathy, but is a disease that may also include aspects of macroangiopathy. This is especially true of renal disease in non-insulin dependent diabetes mellitus (NIDDM), which is characterized not only by diabetic glomerulosclerosis, but also by atherosclerosis. We performed morphological studies on the kidney, using computed tomography (CT), focusing on such points as: (1) abdominal aortic calcifications at the level of kidney, (2) calcifications in the renal artery, and (3) wedge-shaped defects on the renal surface. We noted that these findings became more prominent in NIDDM patients during end-stage renal failure than during normal renal function, and were significantly more common in those two NIDDM groups than in age-matched nondiabetic patients without hypertension, hyperlipidemia or gout. NIDDM patients exhibited these features more frequently than IDDM patients.
