We measured cardiac functions by means of mechanocardiogram and echo-cardiogram in 93 patients with diabetes mellitus, excluding those who had apparent cardiac diseases, such as angina pectoris and cardiac failure. We used pre-ejection-period/ejection time (PEP/ET) as the index of the left ventricular systolic function and isovolumic relaxation time (IRT) as that of the left ventricular diastolic function. We compared the diabetic cases without complications to those with complications such as retinopathy, nephropathy, neuropathy and autonomic disorder. Conclusions obtained were as follows; An abnormal IRT was noted in the early stage of diabetic complications. The IRT was not normal among the subjects even when those with cardiac hypertrophy or ST-depression on the ECG were excluded. On the contrary, the PEP/ET did not show any abnormality in the early stage of diabetic complications until they advanced into, eg. renal failure or severe neuropathy. Our findings suggest that the disorder of the left ventricular diastolic function precedes that of the left ventricular systolic function, indicating the association of microangiopathy and autonomic disorder.

A retrospective study of all patients with systemic lupus erythematosus (SLE) who died at the University Hospital of the West Indies over a 14-year period is presented. The major cause of death was infection followed by renal failure. Gram-negative organisms were the major microbiological agents causing infections. Side-effects of therapy were common, in particular bone marrow depression and haemorrhage related to anticoagulants. It appears that controlling severe lupus activity without increasing the risk of lifethreatening complications remains an important goal in the treatment of SLE.

The present experiment investigated the effects of renal failure and hemodialysis on olfactory identification and response bias assessed by a yes-no task administered both before and 1/2 hr after hemodialysis sessions. Identification and bias were measured under two theories. Results showed that dialysis patients had poorer identification ability overall than their controls which worsened after treatment. Patients' bias was more liberal than controls before treatment but became similar to the controls' afterwards; the bias measures Br and CL were differentially sensitive to diagnosis and time of testing effects. There was a dissociation between discrimination and bias changes in dialysis; patients' bias more closely resembled that seen in dementia (liberal) rather than depression (conservative).

The effect of the calcium antagonist, diltiazem, was examined in gentamicin-induced nephrotoxicity states in rats. Animals were injected for 5 days with diltiazem intraperitoneally (40 mg/kg/day), or gentamicin subcutaneously (100 mg/kg/day) or simultaneously with both preparations using the same doses. At the time of sacrifice, the urea and creatinine clearances, as well as urine osmolality were determined and the renal tissues were processed for examination by light microscopy. Gentamicin-injected rats demonstrated the typical pattern of aminoglycoside nephrotoxicity characterized by poliuric renal failure and necrosis of the proximal tubular epithelium. Rats injected with diltiazem revealed only mild depression of urine osmolality. There was no elevation of blood urea nitrogen and serum creatinine or depression of urea and creatinine clearances, and no focal tubular cell necrosis was detected. However, concomitant administration of both compounds considerably increased nephrotoxicity by according both histological indications and renal function measurements. Thus, we conclude that the combination of diltiazem and gentamicin must be used carefully in human clinical practice.

We used mixed lymphocyte culture (MLC) as an assay to evaluate in vitro the cellular immune functions of children with chronic renal insufficiency (CRI) or with chronic renal failure (CRF). The proliferative response of lymphocytes from both groups of patients was significantly reduced as compared to the response of control individuals. In addition, the proliferative response of CRF patients treated with hemodialysis was significantly lower than the response of continuous ambulatorial peritoneal dialysis (CAPD) patients. These data confirm that a marked depression of the cellular immune response is detectable in a pediatric population, as predicted from data from the literature on the adult renal failure population.

The conventional "stepped-care" approach to the treatment of hypertension deserves revision. Rational therapy considers a variety of factors to obtain maximum efficacy, safety, tolerability, compliance, and neutralization of neural tone for the prevention of sudden death. The patient's age, gender, race, behavior profile, hemodynamic and neurohumoral status (plasma renin activity, norepinephrine/epinephrine ratio), and quality of life will help determine the choice of antihypertensive agent. Concomitant risk factors (smoking, obesity, diabetes, hypercholesterolemia), the presence of sequelae (left ventricular hypertrophy and/or failure, renal failure), and the existence of other disorders (mitral valve prolapse, depression, anxiety) must also be considered when initiating treatment. In addition, the cost of ancillary expenses (laboratory tests, hospitalizations, and emergency room visits) must be weighed against the potential benefits of therapy. Beta blockers are effective, well tolerated, and versatile for the treatment of concomitant cardiovascular disorders and as behavior modifiers. Calcium channel blockers and angiotensin converting enzyme inhibitors also show promise and merit consideration as therapy for specific groups of hypertensive patients.

Twenty patients with end-stage renal failure, undergoing kidney transplantation, were assigned randomly to receive either vecuronium or atracurium under evoked twitch tension control. The cumulative-dose technique was used to obtain 95% twitch depression (vecuronium: initial bolus 15 micrograms kg-1, increments 6 micrograms kg-1; atracurium: initial bolus 100 micrograms kg-1, increments 40 micrograms kg-1). Using ED95 values derived from the log-probit dose-response curves, vecuronium was 4.6 times more potent than atracurium. The durations of action of the initial cumulative-doses (from end of injection of the last increment to 25% recovery) were 11.1 +/- 3.3 min for vecuronium and 16.2 +/- 3.9 min for atracurium (P less than 0.05). In terms of duration of action of the maintenance doses (vecuronium one-quarter of the total incremental dose; atracurium one-third) some cumulation was observed with vecuronium (interaction time X treatment; cumulation ratio 1.46 +/- 0.31 v. 0.98 +/- 0.10 for atracurium, P less than 0.001). After 2 h of surgery, the mean recovery times (25% to 75% twitch height) did not differ (18.5 +/- 2.8 min and 16.7 +/- 4.4 min). It is concluded that vecuronium might be less safe than atracurium in patients with end-stage renal failure undergoing prolonged operations.

Cardiac dysfunction is common in patients with terminal renal failure. However, no consensus has been reached with respect to the indications for digitalis therapy. Depression of myocardial contractility may occur as a result of circulating toxic factors, parathyroid hormone, and altered catecholaminergic responsiveness. On the other hand, paradoxical positive inotropic effects have been observed possibly as a result of a circulating natriuretic factor (an endogenous digitalis analogue) which inhibits Na,K-ATP'ase. Pharmacokinetics and pharmacodynamics of digitalis steroids are altered in uremia. Elimination half-lives of strophanthin and digoxin are prolonged, whereas the elimination half-life of digitoxin is unchanged. Altered protein binding and volume of distribution have been noted. Despite its long elimination half-life, most nephrologists favor administration of digitoxin because of its insensitivity to changes in renal function.

Oral angiotensin converting enzyme inhibition was introduced eight years ago and is becoming increasingly popular for the treatment of hypertension and congestive heart failure. This treatment causes blood pressure lowering associated with suppression of angiotensin and aldosterone, lack of orthostatic hypotension or metabolic disturbances, redistribution of regional blood flows in favor of vital organs and, in the long term, decreased sympathetic drive and regression of left ventricular hypertrophy. It is effective as monotherapy in more than 50 percent of unselected patients; addition of a diuretic increases the percentage of responders to more than 80 percent. It is the treatment of choice for patients with concurrent diabetes, asthma, gout, depression, or very active life-style. Side effects, observed originally in patients with severe hypertension and renal failure treated with very high doses of captopril, are rare in otherwise healthy hypertensive patients receiving smaller doses of this drug and virtually absent with second-generation angiotensin converting enzyme inhibitors like enalapril.

The clinical and laboratory features of 23 new patients as well as 50 previously reported patients with the syndrome of hematophagic histiocytosis are reviewed. The syndrome occurs more often in men than women but has no age predilection. Common presenting features include fever, hepatic and splenic enlargement, lymphadenopathy, and profound depression of blood counts. The clinical course is generally fulminant and may be complicated by coagulation abnormalities, hepatic dysfunction and renal failure. In the majority of patients, however, the syndrome is self-limited with resolution of the clinical and laboratory abnormalities within several weeks. Hematophagic histiocytosis generally occurs in patients who develop infections in the setting of preexisting immunologic abnormalities or neoplasms. Viral infections are most commonly involved, but virtually any other infectious agent can precipitate this syndrome. The characteristic morphologic feature of the hematophagic histiocytosis is the proliferation of mature histiocytes actively ingesting other blood cells. These hematophagic histiocytes most commonly involve the bone marrow but may also be present in the lymph nodes, spleen and liver. Other bone marrow abnormalities include hypocellularity with preservation of megakaryocytes, and myelofibrosis. The principal features of this syndrome that distinguish it from malignant histiocytosis are the cytologic maturity and degree of hematophagic activity of the histiocytes as well as its more favorable prognosis. In some patients, however, a clear distinction of malignant from reactive histiocytosis will not be possible until a clonal marker for malignant histiocytes is identified. Based in our experience, the syndrome of hematophagic histiocytosis appears to be more common than malignant histiocytosis.
