A total of 17,130 children of both sexes born in 1964 and living in Hungary, USSR, GDR and Cuba were examined in 1977. The children were grouped in upper (U) and lower (L) blood pressure groups and 3,640 children were re-examined in 1978-1981. The parents' age, smoking habits, marital status, the children's order of birth, number of siblings, and proportion of twins did not differ between U and L. The prevalence of hypertension and diabetes in the medical history of the children, and the prevalence of hypertension and stroke and diabetes in the medical history of the parents were significantly higher in U than in L. Signs of left ventricular hypertrophy and systolic murmurs, the magnitude of R and S waves in the ECG, and mean values of cardiothoracic and heart volume indices were higher in U than in L. Children in U were sexually more developed, taller, more obese (greater Quetelet's index and skinfold thickness) and less active physically. Average values of blood sugar and serum uric acid were also higher in U than in L. No difference was found between the two groups in the proportion of smokers and in mean cholesterol values. These differences between U and L were strengthened in comparison of children who showed repeatedly low (below the 30th percentile) or high (at or above the 70th, 90th and 95th percentile) readings in the SBP and DBP distribution curves. Since we did not find important differences when we related various factors to blood pressure taken on one or two separate occasions we emphasize the importance of casual blood pressure measurement in childhood.

The immunogenicity of purified pork insulins (PPI) with and without (groups 1 and 2, respectively) trace contamination of beef insulin was contrasted with mixed beef pork insulin of lower purity (MBP, group 3) in 137 patients who had not previously been treated with insulin. Patients and physicians were blinded with regard to the species source of insulin and studies were conducted for a minimum of 1 yr. Antibody development to insulin was assessed by species-specific binding of 125I-insulin by acid charcoal extracted sera, as well as by measurement of insulin prebound to immunoglobulins by a polyethylene glycol precipitation method. NPH- and lente-treated individuals had equivalent antibody responses with regard to the rate of development of antibodies, and maximum immune responses to insulin. In all patient groups, antibody bound insulin as well as species-specific binding of 125I-insulin increased significantly over time (all P less than 0.01 for specific binding of pork and beef insulins SBP and SBB, as well as bound insulin). Maximum bound insulin and SBB as well as bound insulin and SBB over the entire course of the study were significantly greater in group 1 than in group 2 patients (both P less than 0.05). The rate of development and magnitude of antibodies' responses in both PPI-treated groups were significantly less than that seen in the MBP group (all P less than 0.01). New formation of antibeef proinsulin antibodies was seen in one patient from groups 1 and 3, but not in group 2. In all groups, insulin dose per day and fasting serum glucose concentrations increased by about 5 U/day and 10 mg/dl over 1 yr, but groups did not differ. MBP insulin used in these studies proved to be significantly less immunogenic than previously available Argentine pure beef insulin, purified by gel filtration. PPI containing even trace contamination of beef insulin was more immunogenic than PPI alone.

To study the immunologic effects of transfer of patients from animal insulins to human insulin (recombinant DNA), a double-blind comparative trial was begun in over 300 patients. Preliminary results are reported in 116 individuals. After maintenance on purified pork or mixed beef-pork insulins (PPI or MBP) for a minimum of 6 mo, 116 patients were either switched to human insulin or maintained on their previous insulin. Antibody levels were assessed at a baseline visit and then monthly. In PPI-maintained individuals as well as those switched to human insulin there was a significant decrease in qualitative antibody binding as indicated by species-specific binding of 125I beef and human insulins (SBB and SBH), both P less than 0.005. Quantitative binding, as indicated by bound insulin levels, decreased to a much greater extent in patients switched to human insulin, 52% versus 31%, P less than 0.005. Parameters derived from formal antibody titration did not change. In patients maintained on MBP, bound insulin decreased (-36% at 6 mo, P less than 0.002). When switched from MBP to human insulin, there was a marked reduction in all parameters of binding, both qualitative and quantitative: SBP, -68%; SBH, -61%; SBB, -57%; bound insulin, -67% (all P less than 0.001) and decreases in high- and low-affinity binding capacities (P less than 0.02). Thus, for patients treated previously with nonhomologous insulins, transfer to human insulin may result in significant immunologic improvement in anti-insulin antibody levels.

In 1979, a community-wide hospital surveillance system was established in Monroe County, New York (population 702,000), to investigate the continuing contribution of uncontrolled high blood pressure (HBP) to the occurrence of stroke. This paper reports findings among 200 consecutive strokes in persons under 71 years of age. Average age was 58. There was a prestroke history of HBP in 129 (65 per cent) cases. Two-thirds of the 129 had other predisposing conditions (heart disease, diabetes, previous cerebrovascular accident) and 95 per cent had one or more other cardiovascular risk factors (smoking, elevated cholesterol, obesity). Over 90 per cent had visited a physician during the year prior to stroke (average of four visits). Elevated pressures (DBP greater than or equal to 95 or SBP greater than or equal to 160) were recorded at half or more of the visits for 45 per cent of the patients; these cases were classified as uncontrolled. Reduction of "unnecessary" strokes in persons under age 71 should be achievable by giving increased attention to those already under medical care for hypertension who have co-existing stroke risk conditions and cardiovascular risk factors.

To determine the most frequent dyslipidemias among first-degree relatives of NIDDM patients, and its association with their glucose-tolerance status and hyperinsulinemia, we have started to examine members of NIDDM pedigrees, according to American Diabetes Association guidelines for nuclear family studies. In a large family with 2 NIDDM siblings in the 2nd generation, and 4 siblings with NIDDM in the 3rd generation, we have evaluated 14 first degree relatives and also 15 sex and aged matched healthy control subjects without family history of diabetes. The NIDDM relative group presented BMI = 31.8 +/- 3.9 kg/m2, SBP = 128 +/- 18.2 mmHg, DBP = 84 +/- 12.7 mmHg. Both relatives and controls were subjected to a 2h 75g OGTT for glucose and insulin determinations. Although none of NIDDM relatives has IGT, both Glycemic Area (GA) and Insulin Area (IA) were greater (p < 0.01) in the NIDDM relative group. The Insulin/Glucose ratio was also higher (p < 0.01) at 0 and 120 min of OGTT, this might be indirect evidence of Insulin- Resistance. Fasting serum lipids in the NIDDM relatives were TG = 148 +/- 24mg/dl, T-Chol = 244 +/- 10.7mg/dl, HDL-C = 34.2 +/- 2.5mg/dl; lipids in the control group were TG = 84.8 +/- 10.1mg/dl, T-Chol = 167 +/- 10.2mg/dl, HDL-C = 44.4 +/- 2.6mg/dl. Electrophoretic pattern showed type IIa (30.7%) and IIb (61.5%) hyperlipidemias in the NIDDM relatives. In this group, there was a positive and significant association between basal insulin and DBP (r = 0.67; p < 0.01), and between DBP and both TG (r = 0.74; p < 0.01)) and VLDL-C (r = 0.58; p < 0.05). It was also obtained a negative association between basal insulin and HDL-C (r = -0.89; p < 0.001). These data suggest that hyperinsulinemia in association with lipid abnormalities could appear early (before the development of Impaired Glucose Tolerance and Diabetes) in first degree relatives of NIDDM patients.

High blood pressure (BP) is a major factor contributing to the high incidence of cardiovascular morbidity and mortality in haemodialysis (HD) patients. According to predialysis casual BP measurements, long HD has been shown to provide good BP control. To confirm this result during the period between dialysis sessions, we performed ambulatory monitoring of BP in 91 non-selected HD patients (mean age, 58.7 (14.1) years; 14% incidence of nephrosclerosis and diabetes mellitus; treatment duration, 93.0 (77.2) months; 3 x 8 h/week, cuprophane, acetate buffer in 95% of the patients). Only one patient (1.1%) was receiving an antihypertensive medication. Ambulatory BP results were systolic (S) BP, 119.4 (19.9) mmHg; diastolic (D) BP, 70.6 (12.9) mmHg; mean (M) BP, 87.6 (13.9) mmHg. These values were significantly lower than the casual predialysis BP data and close to the reference values reported by Staessen et al. in a meta-analysis including 3476 normotensive subjects. The MBP was inversely correlated with the treatment duration, but not with interdialysis weight gain. The MBP increased significantly in the last part of the interdialysis period, and this rise was not correlated with the interdialysis weight gain. The nocturnal/diurnal ratios for SBP and DBP for the HD patients (0.97 and 0.92) were higher than the reference values reported by Staessen, (0.87 and 0.83), and argued against a nocturnal decrease in BP. We found that 52.1% of the patients had an abnormal nocturnal BP fall (MBP fall < 5%). This feature worsened during the second night of the interdialysis period.(ABSTRACT TRUNCATED AT 250 WORDS)

In essential hypertension reduced diurnal blood pressure (BP) variation is associated with an increased prevalence of target organ damage. We have examined diurnal BP variation in 25 microalbuminuric (MA) and 19 normoalbuminuric (NMA) patients with non-insulin-dependent diabetes and related albumin excretion rate (AER) to diurnal BP variation in the microalbuminuric group. There were no significant differences in age, body mass index (BMI), renal function, diabetic control, clinic or daytime ambulatory BP between the groups. Night-time SBP was higher (MA 145 mm Hg (137-153), NMA 132 mm Hg (125-139); P = 0.019) in the microalbuminuric group while the diurnal variation as assessed by the day-night dip in BP was significantly reduced in the microalbuminuric group (systolic: (mean (95% confidence intervals) MA 4.7% (1.7-7.7), NMA 12.8% (9.5-16.0), p = 0.001; diastolic: MA 6.5% (3.0-10.0), NMA 14.5% (10.2-18.8), P = 0.007). Within the microalbuminuric group, the systolic dip in BP was inversely related to the AER (r = -0.48, P = 0.015). Reduced diurnal BP variation and high night-time BP may contribute to target organ damage in diabetes.

Obesity, especially central, increases the risk of hypertension, hypertriglyceridaemia and diabetes to a significant extent. To determine whether dietary weight reduction can reduce blood pressure (BP) and other cardiovascular risk factors, 217 hypertensives were randomised to receive either 1600 Kcal/day diet (group A, n = 108) or the usual 2100 Kcal/day diet (group B, n = 109). Sodium intake and physical activity were kept similar in both groups. After 16 weeks of follow-up, patients in group A received significantly less energy leading to a 2.8 kg net reduction in mean weight in association with a significant net decrease in mean SBP and DBP (7.5/6.5 mm Hg) compared with nonsignificant changes in group B. There was a significant net decrease in mean total cholesterol (7.0%), low-density lipoprotein (LDL)-cholesterol (7.9%) and triglycerides (8.0%), with a significant net increase in high-density lipoprotein (HDL)-cholesterol (4.0%) in group A compared with group B. New risk factors such as glucose intolerance (8.0%) and central obesity (waist-hip girth ratio, 0.021) showed a significant net reduction compared with group B. Patients with central obesity and other associated disturbances showed maximal reduction in BP and other cardiovascular risk factors with a significantly greater increase in HDL-cholesterol. Mean doses of drugs were similar at entry to the study as well as after 16 weeks in both groups. It is possible that weight reduction due to a low caloric diet can moderate central obesity and associated disturbances in hypertensive subjects.

The effect of essential hypertension at baseline on the development of NIDDM within 6 years was investigated in 465 Chinese nondiabetics with or without hypertension. The age, sex adjusted 6 year incidence of NIDDM in hypertensive group (BP > 18.7 +/- 12. okPa (140/90 mmHg) or treated with antihypertensives) at baseline was significantly higher than that in normotensive group (44.6%, n = 325, P < 0.05) at baseline. Multivariate regression analysis showed the hypertensive group had higher risk of worsening to diabetes compared with normotensives (OR: 1.82, 95% Ci: 1.03-3.21, P < 0.05) after the adjustment for two other important risk factors for NIDDM, the fasting plasma glucose and BMI. Further more the increasement of SBP by 20 mmHg at baseline significantly increase the risk for NIDDM in the followup period in the blood-lowering-drug-free group (OR: 1.54, 95% Ci: 1.05-2.24, P < 0.05). Thus it confirmed that hypertension at baseline was an independent predictor for NIDDM. In addition, our observation showed that some antihypertensive drugs appears also to play an unfavorable role in the occurrence of NIDDM.

The aim of this study was to evaluate the relationship between nocturnal blood pressure (BP) (by ambulatory blood pressure monitoring, ABPM) and urinary albumin excretion (UAE) in hypertensive patients with type II diabetes mellitus. We studied 179 essential hypertensives (WHO I-II), all males, with non-insulin-dependent diabetes. Non-invasive ABPM was performed by a fully automatic, portable device (Spacelabs 90202), set to take readings at 15-min intervals during both day-time 7 AM to 1 PM and nighttime (1 PM to 7 AM). According to the day/night reduction in mean blood pressure (MBP), three groups were identified: group I, nocturnal MBP reduction > 10%; group II, day/night MBP reduction of 5% to 10%; and group III, day/night MBP reduction < 5%. The mean values of UAE as well as the prevalence of microalbuminuria (UAE > 30 mg/24 h) were found to be significantly higher in group III as compared to the other two groups. Besides, in group III UAE displayed a significant negative relationship with the SBP and MBP (but not DBP) nocturnal drop and a positive relationship with the duration of hypertension and duration of diabetes. In group II, UAE was weakly correlated only with the duration of hypertension, whereas in group I no significant correlation was found between UAE and other parameters of the study. These results indicate that in hypertensive type II diabetic patients a blunted nocturnal BP fall is associated with higher UAE and increased prevalence of microalbuminuria. Whether the reduced day/night BP difference is the cause of consequence of target organ damage remains to be established.
