Left ventricular function was assessed by measuring sytolic time intervals in insulin-requiring diabetics with and without significant microangiopathy. The results were compared with those in normal controls. Significant microangiopathy was defined as proteinuria over 3 g/24 h or proliferative retinopathy. Left ventricular function was also assessed one and a half years later by echocardiography in four patients with microangiopathy. Patients with angina, previous myocardial infarction, hypertension, and alcoholism were excluded. All had normal electrocardiograms and chest radiographs. Diabetics with microangiopathy had impaired left ventricular function, whereas those with uncomplicated diabetes had normal function. This finding supports the existence of a specific diabetic cardiomyopathy due to microangiopathy rather than the metabolic defect. The association of microangiopathy and impaired left ventricular function may explain the high immediate mortality and the high incidence of cardiogenic shock and congestive heart failure after myocardial infarction in diabetics.

A personal series of 6780 patients with diabetes mellitus is reported. Of these 1410 were thought to have insulin-dependent (Type 1) diabetes and 4926 non-insulin-dependent (Type 2) diabetes. Among the former, 128 patients were only diagnosed when in severe ketoacidosis or coma. In 116 patients the diabetes was diagnosed in pregnancy. Chronic alcoholism was an aetiological factor in 75 patients; in 52 it led to the diagnosis being made, and it complicated treatment in 129 additional patients. In the patients with Type 2 diabetes whose treatment was stabilized 23.5% were having insulin injections, 44.5% tablets, and 32.0% diet only. Sight-threatening retinopathy developed in 21.3% of patients with Type 1 and 7.9% of those with Type 2 diabetes. The rate of developing sight-threatening retinopathy was 1.1% of patients per year. Blindness occurred in 0.28% of patients with Type 1 diabetes per year and 0.097% per year in Type 2 diabetes. If the mean survival of patients with retinopathy going blind is 7.5 years, this would mean 7500 people in the UK blind from diabetic retinopathy. There was a striking drop in the annual incidence of blindness after 1970 coinciding with the introduction of specific treatment for diabetic retinopathy. Juvenile cataract developed in 1.7% of patients who developed Type 1 diabetes before 30 years of age. Clinically important diabetic neuropathy developed in 17.4% of patients with Type 1 and 11.6% of those with Type 2 diabetes. The main features were paraesthesiae and numbness (49%), neuropathic ulceration (37%), pain (5%), autonomic symptoms (5%), and amyotrophy (4%). Oculomotor palsies and mononeuropathies were noted. Foot ulceration occurred in 81 patients with Type 1 and 279 of those with Type 2 diabetes. Charcot changes in the feet were noted in 21 patients. Major amputations were needed in 18 patients with Type 1 and 60 with Type 2 diabetes. Proteinuria believed to be due to diabetic nephropathy developed in 12.8% of patients with Type 1 and 4.7% of those with Type 2 diabetes. The prevalence of early renal failure was 4.6% and 1.4%, respectively. Coronary artery disease was noted in 9% of patients with Type 1 diabetes, and was more common in those who developed diabetes after 20 years of age. Myocardial infarction was as common in women as in men. In Type 2 diabetes coronary artery disease gave rise to symptoms in 19.1%, and myocardial infarction was more common in men.(ABSTRACT TRUNCATED AT 400 WORDS)

Proteinuria, hematuria and leukocyturia in chronic alcoholics were mostly pronounced in abstinence, particularly in those with a long-term alcoholism. In proportion to alcohol d s-intoxication treatment, their urinalyses normalized. Being hospitalized in a sober state the patients had insignificantly elevated or practically normal urinalyses. Disulfiramum tests performed both in abstinence or sobriety demonstrated pronounced abnormalities in urinalyses. In the course of disulfuramum treatment in the absence of alcohol tests urinalyses normalized completely. Urinalysis follow-up demonstrated the appearance of renal failure due to hemodynamic disorders that ran the pattern of renal sensitization due to the effect of acetaldehyde production in alcohol tests.

The paper is concerned with the results of a long-term study with clinicomorphological correlations of 86 patients with alcoholic glomerulonephritis (GN), i. e. 12% of all morphologically verified cases of primary GN. GN clinical features in alcoholism were painless microhematuria, moderate hyperuricemia, frequent combination with the alcoholic involvement of the other organs and the elevated blood serum IgA level. An important diagnostic sign in alcoholic GN was a positive clinicolaboratory time course in abstinence. A morphological study showed prevalence of mesangioproliferative GN with deposits containing IgA and C3, often with a noticeable tubulointerstitial component and fibroplastic glomerular transformation. The accumulation of podocytes and nephrocytes of intermediate filaments in the cytoplasm should be regarded as an important morphological feature of alcoholic GN. An unfavorable course of alcoholic GN with an outcome into chronic renal failure was observed in 35% of the patients. Prognostically unfavorable signs were the age under 40, the presence of considerable proteinuria (over 1 g/day), the nephrotic syndrome, the detection of the glomerular immune complexes, a tubulointerstitial component, fibroplastic transformation of mesangioproliferative nephritis as well as the detection of mesangiocapillary, diffuse fibroplastic and extracapillary nephritis.

Heavy alcohol intake and/or lipotrope-deficient diet induced hepatocellular injury and mesangial deposition of IgA and often IgG in Lewis rats. The experimental animals showing more severe urinary abnormalities and histologic damage in the glomeruli had increased levels of IgA antibodies to dietary antigens and altered intestinal permeability. Based on human studies, the prolonged circulation of IgA-containing complexes associated with the liver disease could be envisaged as important for the development of mesangial IgA deposits. In order to verify this hypothesis, four groups (G) of Lewis rats were studied: G1 received thrice a weak an intragastric infusion of 1.5 ml/100 g body wt of whiskey; G2 rats were nourished with lipotrope-deficient diet; G3 rats were given both whiskey and LD diet; G4 rats were nourished with regular chow. After 12 weeks, heat-aggregated rat monomeric IgA was labeled with 133I and intravenously injected. Three control subgroups of rats, one given whiskey, one nourished with LD diet, and one with regular chow, were injected with radiolabeled heat-aggregated rat IgG. A large field-of-view digital gamma camera, equipped with an ultra-high-resolution collimator and interfaced to a dedicated computer, was used to analyze tracer kinetics and fate. The liver was the main organ involved in clearance of both test probes. The hepatic mean transit (MTT) was 11.4 +/- 11 min in G1 (proteinuria of 6.9 +/- 1.41 mg/day and hematuria +/+2), 221 +/- 19 min in G2 (proteinuria 9.1 +/- 0.64 mg/day and hematuria +2/+3), and 230 +/- 15 min in G3 (proteinuria 9.5 +/- 0.58 mg/day and hematuria +2/+3). In each case MTT value was found to be significantly prolonged compared to G4 (85 +/- 4 min). The multiple regression analysis showed that MTT values, proteinuria, and hematuria were significantly correlated (P < 0.01). Controls had trace amount proteinuria (0.82 +/- 0.17 mg/day, significantly lower than for each study group, P < 0.08) and undetectable hematuria. Similar results were obtained in control rats injected with aggregated IgG; i.e., MTT values were more prolonged in rats given whiskey or LD diet than normally nourished rats (P < 0.01). The lipotrope-deficient diet and the chronic alcohol abuse per se seem to lead to critical changes in hepatic uptake and catabolism of both an IgA and an IgG aggregate, which could account in turn for the reported appearance of renal immunoglobulin deposits in this experimental model. Due to the comparable delay in removal of IgA and IgG probes in equally nourished animals, additional factors are likely to be involved in the prominent deposition of IgA.

Urinalysis was carried out in 231 inpatients with alcohol dependence syndrome (215 males and 16 females). Fifty-nine patients (25.5%) showed proteinuria, 97 (42.0%) showed glucosuria, and 62 patients (26.8%) showed hematuria on admission. A total of 135 out of 231 patients (58.4%) showed abnormal urinalysis. Proteinuria was related to high blood pressure, high serum glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, lactate dehydrogenase, uric acid, and triglyceride levels, and high urinary amylase concentration. Glucosuria was related to high serum glutamic-oxaloacetic transaminase concentration and a history of gastrectomy. Hematuria was related to high age and high urinary amylase levels. By chi-square test, there was a significant correlation between proteinuria and hematuria (p < 0.001) and between hematuria and glucosuria (p < 0.001), but no correlation was found between proteinuria and glucosuria. The incidence of diabetes mellitus was 10.8% (25 out of 231 patients), but transient hyperglycemia was observed in some patients without diabetes mellitus on admission. Elevated hemoglobin A1, hemoglobin A1c, and fructosamine concentrations were observed in patients with either impaired glucose tolerance or transient hyperglycemia, which suggested the presence of persistent hyperglycemia before admission. On discharge, only 12 out of 198 patients (6.1%) showed abnormal urinalysis. We report that heavy ethanol consumption induces transient abnormal urinalysis results in Japanese alcoholics.

The aim of the study was to analyze the etiology, the factors for progression of chronic renal failure to end-stage-renal disease (ESRD), and the influence of ESRD on the survival rate among a cohort of 59 heart transplant patients (HTP) referred for the management of chronic renal failure (CRF). At the time of the first nephrology consultation (6 +/- 4.25 years after cardiac transplantation) the mean creatininemia was 261.5 +/- 99 micromol/L and mean creatinine clearance (Cockcroft formula) was 32 +/- 15 mL/min. The cause of CRF were calcineurin inhibitor toxicity in 38.9% of patients, vascular events in 15.2%, hemolytic uremic syndrome in 5%, membranous glomerulopathy in 3.3%, diabetes in two patients, focal/segmental glomerulosclerosis in 3.3%, renal hypoplasia in 1.7%, and unknown in 27%. Evolution to ESRD occurred in 38.9% of patients: 17 patients started hemodialysis, three peritoneal dialysis, and two received a preemptive kidney transplantation. Creatininemia (micromol/L) at the time of nephrology referral was 229.2 +/- 72.6 versus 315.8 +/- 113.4 (P < .001) and creatinine clearance (mL/min) was 34.9 +/- 15.1 versus 27.3 +/- 13.7 (P = .049) for patients with CRF versus ESRD, respectively. Both proteinuria (g/24 hours) of 1 +/- 2.2 versus 2.3 +/- 1.8 (P = .02) and tobacco use in 35.1% versus 54.4% (P = .045) were significantly associated with progression of CRF, while age at the time of heart transplantation, cause of cardiac failure and renal failure, high blood pressure, type 2 diabetes, dyslipidemia, alcoholism, cirrhosis, and cerebral vascular accident were not. Death occurred in 18 HTP: 50% of patients with ESRD and 18.5% of patients with CRF-a 2.6 relative risk of of death in HTP patients with ESRD compared with HTP with CRF only (P < .01).
