A multicenter, double-blind, randomized, and placebo-controlled trial, the Perindopril Therapeutic Safety Study (PUTS), was designed to assess the interaction between angiotensin-converting enzyme (ACE) inhibition and the diseases and therapies commonly found associated with mild hypertension. A total of 480 male and female patients aged 30-70 years with a diastolic pressure of 90-104 mm Hg were included after a 3-week placebo run-in if they satisfied standard criteria for any of the following: hyperlipidemia, type II diabetes, ischemic heart disease, cardiac arrhythmia, peripheral arterial occlusive disease, nephropathy with proteinuria, chronic obstructive lung disease or treatment with nonsteroidal anti-inflammatory drugs (NSAIDs). At the end of the placebo run-in period, patients were randomly assigned to either placebo or perindopril 4 mg once daily. A total of 460 patients completed the 6-week double-blind phase, comprising 3 assessments at 1, 3, and 6 weeks. In this report, the principal results obtained in 5 disease groups (hyperlipidemia, type II diabetes, ischemic heart disease, nephropathy with proteinuria, and NSAID treatment) will be reported. A total of 269 patients belonging to one of the aforementioned 5 disease groups completed the double-blind phase of the study and were included for statistical evaluation. In the perindopril group, systolic and diastolic blood pressures decreased significantly more than in the placebo group, and a sitting diastolic blood pressure of 90 mm Hg was achieved in 65% of patients in the perindopril group and 30% of patients in the placebo group. The incidence of symptoms spontaneously reported by the patients was low: 2 patients of the perindopril group complained of cough.(ABSTRACT TRUNCATED AT 250 WORDS)

In patients without significant cardiovascular disease, the hemodynamic effects of sevoflurane and isoflurane are similar; however, the hemodynamic effects of sevoflurane in patients with hypertension and ischemic heart disease are unknown. To examine the effects of sevoflurane in comparison to isoflurane in this high-risk population, 214 patients scheduled for elective surgery were enrolled if they had evidence of ischemic heart disease or multiple risk factors for ischemic heart disease. Patients were randomly assigned to receive sevoflurane (n = 106) or isoflurane (n = 108) for anesthetic maintenance in conjunction with fentanyl and nitrous oxide in oxygen. Deviations in arterial blood pressure or heart rate of more than 20% from preinduction values that persisted after adjustment of the volatile anesthetic concentration were treated with intravenous phenylephrine, ephedrine, nitroglycerin, atropine, or esmolol as needed. Creatinine, blood urea nitrogen (BUN), and urine protein were measured before surgery, immediately after surgery, and 24 and 48 h postoperatively. For analysis, patients were divided into those with and those without the diagnosis of chronic hypertension. Heart rate and arterial blood pressure responses to sevoflurane and isoflurane were not different for the patients with or without chronic hypertension. Neither anesthetic was associated with a more frequent treatment for hemodynamic deviation. After surgery, creatinine and BUN decreased in both the sevoflurane and isoflurane groups without significant differences between groups. The incidence of post-operative proteinuria was similar in the sevoflurane and isoflurane groups. We conclude that hemodynamic stability in patients with hypertension and ischemic heart disease is similar with sevoflurane and isoflurane. No differences in renal function were observed between the sevoflurane and isoflurane groups.

A group of 146 patients with non-insulin- dependent diabetes mellitus (NIDDM) was studied. They were divided into two groups of 73 age and sex matched patients, according to the presence or absence of hypertension. We recorded the presence of macrovascular and microvascular complications of NIDDM, family history, body mass index (BMI), glycemic control and lipidic profile. Renal parameters included plasma creatinine, urinary albumin excretion rate (UAER), glomerular filtration rate (GFR), effective renal plasma flow (ERPF) and filtration fraction. Hypertensive patients had a higher BMI (30 +/- 4.8 kg/m2 vs. 27.6 +/- 4.4 kg/m2, P < 0.005), total cholesterol (6.34 +/- 1.47 mmol/l vs. 5.72 +/- 1.14 mmol/liter, P < 0.01), creatinine (91.1 +/- 25.6 mumol/liter vs. 81.3 +/- 20.3 mumol/liter, P < 0.05) and UAER [63.7 (range 1 to 5160) mg/24 hr vs. 27.3 (3 to 5500) mg/24 hr, P < 0.001]. GFR was lower in the group with hypertension (113 +/- 35 ml.min-1.1.73 m-2 vs. 127 +/- 29 ml.min-1.1.73 m-2, P < 0.05), but there were no differences in ERPF. The difference in GFR was only apparent in patients without established diabetic nephropathy. Hypertensive patients had higher frequency of ischemic heart disease (18% vs. 6%, P < 0.05) and diabetic nephropathy (62% vs. 38%, P < 0.005). We conclude hypertensive NIDDM patients, when compared with normotensive NIDDM patients, are more obese, hypercholesterolemic and have a higher frequency of ischemic heart disease and diabetic nephropathy. Hypertensive NIDDM patients have a worse renal function than normotensives before clinical proteinuria appears. The deterioration of GFR in hypertensive NIDDM patients possibly has an important influence on the progression of diabetic nephropathy.

The WHO Multinational Study of Vascular Disease in Diabetes was launched in 1975-77 to investigate international variations in the occurrence of different manifestations of vascular disease in subjects with insulin-dependent and non-insulin-dependent diabetes. A morbidity and mortality follow-up extending until January 1, 1988 was carried out in 10 centres, including five European centres (London, Switzerland, Berlin, Warsaw and Zagreb), two East Asian centres (Hong Kong and Tokyo), two Native American centres (Arizona and Oklahoma) and one Caribbean centre (Havana). Of a total of 4714 diabetic subjects (2310 men and 2404 women) aged between 35 and 55 years at baseline who were successfully followed up, 1266 were classified as having insulin-dependent diabetes and 3448 as having non-insulin-dependent diabetes. There was a large variation between the centres in ischaemic heart disease and cerebrovascular disease mortality rates for both insulin-dependent and non-insulin-dependent diabetic subjects, presumably reflecting in part differences between the background populations in mortality rates from these cardiovascular causes. The lowest ischaemic heart disease mortality rates for diabetic subjects were observed in Hong Kong and Tokyo centres, representing industrialized countries which have continued to have low ischaemic heart disease mortality rates. The importance of raised blood pressure and proteinuria as potentially modifiable cardiovascular risk factors in diabetic subjects was confirmed in this study.

We assessed the clinical characteristics of newly-diagnosed diabetic patients presenting to the Mulago Hospital Diabetic Clinic for the first time between 1 January 1993 and 10 August 1994. There were 252 patients: 117 men and 135 women. Mean age at onset of diabetes was 45 years (range 2-87 years) and peak incidence was at 40-49 years. Body mass index (BMI) was available in only 71 patients, of whom 53.5% (33.8% female, 19.7% male) were overweight (BMI > 25 in women, in > 27 men) and 11.3% (8.5% men, 2.8% women) were underweight (BMI < 20). Obesity was more marked in young women. Almost all patients presented with the classical symptoms of diabetes, and the majority were severely hyperglycaemic. A family history of diabetes was identified in 16%. Concurrent illnesses at diagnosis of diabetes were unusual. Sepsis was commonest (11.9%), followed by malaria (7.8%), tuberculosis (1.2%), AIDS (1.2%) and pancreatitis (0.8%). Peripheral neuropathy was present in 46.4% of patients, hypertension (BP > 150/100) in 27.3%, impotence in 22.2% of the men, proteinuria in 17.1%, ischaemic heart disease in 4.8%, foot ulcers in 4.0% and cataracts in 3.2%. Insulin was the most commonly prescribed treatment (52.8%); 31% of patients received oral hypoglycaemic agents, only 15.1% were managed on diet only, and 1.2% opted for herbal medicine.

In many reports, the prevalence of target organ damage in renovascular hypertension (RVH) appears to be higher than in essential hypertension (EH). Since in most studies the renal artery stenosis is part of a diffuse atherosclerotic disease, it is not known whether these complications are due to RVH itself or to the vascular disease. We have undertaken a case control study of 92 patients divided into two groups (46 in each), one with RVH and the other with EH and abdominal aortic aneurysm, with a comparable degree of diffuse atherosclerotic vascular disease. The vascular state of the extracranial carotid arteries and abdominal and inferior limb districts was investigated with angiography and sonography. The prevalence of left ventricular hypertrophy (LVH) and ischemic heart disease (IHD) were assessed by electrocardiography. Serum creatinine and urinary protein excretion were employed in the renal evaluation. While the analysis of the results confirmed an even diffusion of atherosclerotic vascular disease between the two groups, a significant difference was found in the prevalence of heart and renal damage. LVH was present in 32.6% of RVH patients versus 10.8% in EH (P = .02). Serum creatinine > 1.4 mg/dL was found in 50% of RVH and in 23.9% of EH, (P = .01). The prevalence of proteinuria in RVH was also higher although not reaching the statistical significance. The results suggest that, in patients with comparable degrees of atherosclerotic vascular disease, RVH is responsible for the higher prevalence of target organ damage in this condition compared to those with EH.

We studied the relationship between clinical characteristics and renal structural changes in 29 elderly patients in whom non-insulin-dependent diabetes mellitus was diagnosed when they were 60 years of age or older. The clinical stage of nephropathy was graded according to the criteria of the Ministry of Health and Welfare of Japan: stage 1 (12 patients), normoalbuminuria; stage 2 (11 patients), microalbuminuria; stage 3 (1 patient), persistent proteinuria; stage 4 (5 patients), chronic renal failure. Renal biopsy specimens were semiquantitatively evaluated with regard to diffuse glomerular lesions, nodular lesions, and vascular lesions. In patients at stage 1, minimal-to-moderate diffuse lesions were observed, and vascular lesions were already present. In patients at stage 2, various alterations in diffuse lesions were observed and were associated with prominent changes in the vascular lesions. More advanced changes in the diffuse and vascular lesions were noted in patients at stages 3 and 4, but nodular lesions were found in only one patient. These patients had a high incidence of hypertension and ischemic heart disease. We conclude that elderly diabetic patients with nephropathy of different clinical stages have different underlying diabetic renal lesions.

To determine the prevalence of unrecognized silent myocardial ischemia, 925 noninsulin-dependent diabetic outpatients (333 women and 592 men), aged 40 to 65 years, asymptomatic, free from known coronary artery disease (CAD), advanced diabetic retinopathy, and nephropathy, severe hypertension, and poor prognosis disease, underwent exercise electrocardiogram (ECG), followed, if abnormal, by an exercise thallium scintigraphy. The exercise ECG tests were abnormal in 112 patients (12.1%, 31 women, 81 men), of whom 59 (6.4%, 12 women, 47 men) had perfusion defects at thallium scintigraphy. Adopting the more restrictive criteria (positive response to both tests) the prevalence of silent CAD resulted in 6.4%. Multivariate analysis showed that in the whole population and in the men, the associated independent risk factors were age, total cholesterol, proteinuria, and ST-T abnormalities at ECG at rest. This last factor had the highest odds ratio (9.27, confidence interval [CI] 4.44 to 19.38) and was the only one identified also in women. The relevance of ST-T abnormalities at ECG at rest as a predicting factor for silent CAD outlines the importance of a periodical ECG at rest in noninsulin-dependent diabetic patients and suggests an indication of performance of further investigations in presence of these abnormalities.

To gain current data about epidemiology of diabetic retinopathy in a population of type 2 diabetics a long-term prospective study was started. The study included 1334 patients with type 2 diabetes mellitus registered in Warsaw regional Diabetes Center. The prevalence of any form of diabetic retinopathy in this group was 31.4% and proliferative retinopathy-1.3%. It was found that the patients with retinopathy had diabetes mellitus of longer duration, higher fasting and postprandial levels of glycemia and higher daily proteinuria in comparison with diabetics without retinopathy. Apart from that, a frequency of ischemic heart disease and lower extremity ischemic disease was higher in diabetics with retinopathy. 109 new cases of retinopathy were diagnosed during 3-year follow-up. The study allowed us to determine the current epidemiological parameters concerning diabetic retinopathy in type 2 diabetics and a set of parameters characterizing people at highest risk of a development of retinopathy.

The greatest change in GFR in response to treatment with cyclosporin occurs in the first 3-6 months and the magnitude of the decrement in the first year (or perhaps the first few months) appears to be a vital indicator of future problems. However, the apparent stabilization of renal function, particularly when monitored only by plasma creatinine, can conceal progressive tubulointerstitial injury, and increasing proteinuria is an ominous sign. Although lower doses of cyclosporin and careful monitoring of renal function may be helpful, there is at present no pharmacological intervention to protect or reverse the reduction in GFR that occurs. We believe that the vascular lesion induced by cyclosporin is fundamental, with early and initially reversible cyclosporin-induced vasospasm leading to progressive vascular damage with activation of endothelial cells and increased platelet interactions. Amongst other determinants, the renal response to this vasculopathy will depend on the balance between the presence of vasoactive factors with the vasoconstrictors promoting interstitial fibrosis and the vasodilators inhibiting proliferation. It is likely that the kidneys of heart-transplant recipients are chronically ischaemic and as a consequence their renin-angiotensin systems massively activated, which may further sensitize their kidneys to cyclosporin. Overproduction of angiotensin II, associated with the DD ACE genotype, has already been associated with poor prognosis in diabetic and IgA nephropathy. It is interesting to speculate that this ACE genotype, which is associated with a poor outcome in non-ischaemic heart disease can influence renal sensitivity to cyclosporin and predict the development of morphological injury. Extension of these experimental findings into the clinical arena with a placebo-controlled trial of early introduction of ACE inhibitor therapy in recipients of cardiac transplants would be timely.
