Management of the vascular access (VA) for renal replacement therapy (RRT) in acute renal failure (ARF) patients is faced with a twofold problem: first, the creation of an angio-access that is adequate for RRT in the acute setting; second, the preservation of the patient's vascular network in order not to preclude further use of the vessel in the event of evolution to chronic renal failure. Central venous catheters are the preferred VA for RRT in the intensive care setting. Semi-rigid double-lumen polyurethane catheters may be considered for short-time use (up to 2-3 weeks). Soft silicone double-lumen or twin-catheters, preferably with subcutaneous tunnelling, are highly desirable for prolonged RRT (over 3 weeks). The femoral route is the first option in the presence of associated risk factors (respiratory failure, pulmonary oedema, bleeding...). The internal jugular route should be considered for mid-term use in order to facilitate the patient's mobilization and to reduce the risk of infection. The subclavian route should be avoided because of the risk of stenosis and/or thrombosis of the outflow vein. Catheter insertion must be performed by a trained physician with ultrasound guidance using either skin mapping or continuous vein guidance. Catheter handling and care should comply with best practice guidelines and should be part of a continuous quality improvement programme in order to reduce catheter-related morbidity. Preservation of the upper limb vascular network of the patient consists of sparing the native vessels (artery and vein) of the patient and preserving the functionality of the permanent VA in chronic renal failure patient. This 'lifeline' of chronic renal failure patients may be maintained by preventing inflammation, infection and thrombosis of the superficial vessels of the arm and forearm of patient.

The study was held in order to analyze the main causes of death in cases of rheumatic diseases (RD) in Moscow. The authors studied the pathology records of autopsies performed in 1999-2002 in two pathology departments of Moscow clinics. Cases with RD were selected. The study found 165 cases of RD, which constituted 2% of all autopsies performed in these departments. There were 99 cases (60%) of rheumatic heart disease (RHD), 4 cases (2.4%) of rheumatic fever (RF) relapse, 28 cases (17%) of rheumatoid arthritis (RA), 8 cases (4.8%) of systemic lupus erythematosus (SLE), 3 cases (1.8%) of scleroderma systematica (SS), 2 cases (1.2%) of ankylosing spondylitis (AS), 2 cases (1.2%) of systemic vasculitis (SPV), 11 cases (7.3%) of osteoarthrosis, 3 cases (1.8%) of gout, 1 case (0.6%) of polymyositis. The death of patients with RHD had been caused by hemodynamic decompensation (HD) in 54% of the cases, acute cardiovascular collapse (ACC) in 14% of the cases, 6% of the patients had died from thromboembolism (TE) and 26%--from other conditions (intoxication, uremia, brain and lung edema etc). The death of patients with RF was caused by TE in 2 cases, by HD in 1 case and by ACC in 1 case. Secondary amyloidosis resulting in chronic renal failure and uremia occurred in 5 out of 28 cases of RA, HD--in 3, ACC--in 7, TE--in 1, infectious complications--in 5, other complications--in 7 cases. Patients with SLE died from various conditions: uremia in 2 cases, acute adrenal failure in 1 case, infectious complications in 2, ACC--in 2, brain edema--in 1 case. The complications of SS were uremia and intoxication. ACC was the cause of death in cases of gout and SS. The majority of RD cases were patients with RHD. The main cause of death in RD was cardiovascular disorders.

Lung and kidney function are intimately related in both health and disease. Respiratory changes help to mitigate the systemic effects of renal acid-base disturbances, and the reverse is also true, although renal compensation occurs more slowly than its respiratory counterpart. A large number of diseases affect both the lungs and the kidneys, presenting most often with alveolar hemorrhage and glomerulonephritis. Most of these conditions are uncommon or rare, although three of them--Wegener's granulomatosis, systemic lupus erythematosus, and Goodpasture's syndrome--are not infrequently encountered by respiratory care clinicians. Respiratory complications of chronic renal failure include pulmonary edema, fibrinous pleuritis, pulmonary calcification, and a predisposition to tuberculosis. Urinothorax is a rare entity associated with obstructive uropathy. Sleep disturbances are extremely common in patients with end-stage renal disease, with sleep apnea occurring in 60% or more of such patients. The management of patients with acute renal failure is frequently complicated by pulmonary edema and the effects of both fluid overload and metabolic acidosis. These processes affect the management of mechanical ventilation in such patients and may interfere with weaning. Successful lung-protective ventilation in patients with acute lung injury and renal failure may require modification of hemodialysis in order to combat severe acidemia. Hemodialysis-related hypoxemia, which was once believed to be the result of pulmonary leukostasis and complement activation, is explained by diffusion of CO2 into the dialysate, with concomitant alveolar hypoventilation in the process of maintaining a normal P(aCO2). Like acute lung injury, renal failure is a common complication of critical illness. An increasing body of evidence also supports the notion that the kidneys, like the lungs, are susceptible to injury induced as a result of positive-pressure mechanical ventilation.

The prevalence and significance of sleep-disordered breathing (SDB) in dialysis-independent chronic renal failure (CRF) remains unknown. We studied the presence of SDB in nondialyzed CRF patients. Diagnostic polysomnography was performed in consecutive stable nondialyzed CRF patients. Inclusion criteria were age <or=70 years, absence of systolic dysfunction or history of pulmonary edema, FEV(1) > 70% pr, absence of neurologic disease or hypothyroidism, and calculated creatinine clearance <40 ml/min. Thirty-five patients (19 male, 16 female) were studied. An apnea-hypopnea index (AHI) >or=5/h was present in 54.3% (almost exclusively obstructive events). AHI correlated with urea (r = 0.35, p = 0.037), age (r = 0.379, p = 0.025), and body mass index (BMI) (r = 0.351, p = 0.038), but not with creatinine clearance. AHI or SDB were unrelated to gender. In nondiabetics (n = 25), AHI correlated with urea (r = 0.608, p = 0.001) and creatinine clearance (r = -0.50, p = 0.012). Nondiabetics with severe CRF (calculated GFR < 15 ml/min/1.73 m(2)) had a significantly higher AHI compared with less severe CRF. Restless legs syndrome (RLS) was present in 37.1% and periodic limb movements in 28.6%. Daytime sleepiness was not associated with respiratory events, but was more common in patients with RLS. The prevalence of SDB and RLS is high in dialysis-independent CRF. SDB weakly correlates with indices of kidney function and this association becomes stronger in nondiabetics.

Pulmonary complications are common in patients with chronic renal failure (CRF). The objective of this study was determine the effect of renal transplantation on pulmonary function, using a methacholine challenge test. This interventional study included 14 CRF patients on maintenance dialysis who underwent serial spirometry and astography before and after renal transplantation. None of them was known to have clinically important pulmonary or heart disease. The results of spirometry, astography, echocardiography, and chest X-ray were normal. Five patients were men and all others were women. The overall age range was 15 to 45 years (mean age = 28.6 +/- 10.9). For every patient four times astography was done. The mean values of spirometric and astography indices before and after renal transplantation were within normal limit. But by repeated measure analysis of variance, the results actually showed improved airway responsiveness (although within normal limits). The most common pathological lung condition in CRF is pulmonary edema, usually due to a combination of fluid overload and abnormal permeability of the pulmonary microcirculation. However, our patients had no symptomatic pulmonary edema, but minor degrees of fluid retention are virtually impossible to detect clinically and could not be excluded. Therefore, it seems that disappearance of subclinical pulmonary edema was the likeliest cause of an increase in minimum dose of methacholine, and therefore improvement in airway responsiveness after renal transplantation.

The potential benefits of early referral to a nephrologist of chronic uremics include slowing the rate of decline associated with progressive renal insufficiency and facilitating efficient entry into dialysis programs. Late referral is associated with complications that are uncommon among early referrals. This study aim to evaluate the pattern of referral among chronic uremics with a view to identifying associated problems. All the patients seen with chronic renal failure during a five-year period in the dialysis unit of the hospital had their medical records reviewed. Information was extracted on the clinical data and laboratory records. Ninety patients were seen in the dialysis unit of the hospital during this period. The mean age was 38.3+ 1.6 years (range 10-69 years) with a peak incidence in the second decade. Most patients were referred late from the private medical clinics 34(37.8 % ) and the general hospitals 32(35.6 % ). Seventy (77.8 % ) patients were initially diagnosed as chronic uremics, six months prior to referral. The aim of referring in most cases was persistent uremic symptoms and necessity for dialysis. Only 14(15.6 %) patients presented without complications. The commonest were pulmonary edema, (28.9 % ) biventricular failure (22.2 % ) and hypertension (20 % ). The majority of the patients were referred late to nephrologists and presented with complications. Chronic Renal Failure patients should be referred early to nephrologists so as to prevent/reduce morbidity and mortality.

Case 1: A 38-year-old female with a history of tonsillitis and sinusitis was admitted to our hospital because of lung edema. On admission, her serum creatinine increased to 5.57 mg/dL. Hypocomplementemia was not found. ASO and MPO-ANCA were 24 U/mL and 12 EU, respectively. She underwent emergency hemodialysis. Renal biopsy showed global sclerosis and fibrocellular crescentic formation, and marked angionecrosis was noted by light microscopy. Granular deposition of C3, IgG and IgM was seen along the capillary walls on immunofluorescence study. Glomerular intramembranous deposits were scattered on electron microscopy. She was treated with intravenous methylprednisolone pulse therapy, and following oral prednisolone administration was decreased gradually. No therapeutic effects were observed, and intermittent hemodialysis was continued and became maintenance hemodialysis therapy. Case 2: A 28-year-old female suffering from both pharyngitis and acute renal failure with systemic edema was admitted to our hospital. On admission, her serum creatinine and ASO were 4.31 mg/dL and 239 U/mL, respectively. MPO-ANCA was negative and CH50 was normal. Hemodialysis was initiated on the 6th hospital day. In renal biopsy, most glomeruli showed cellular crescentic formation, and marked angionecrosis was noted by light microscopy. Global sclerosis was not found in this case. Granular deposition of C3 resembling a starry sky pattern was seen along the capillary walls on immunofluorescence study. Electron microscopy revealed scattered glomerular subepithelial deposits. She was treated with intravenous methylprednisolone pulse therapy and then oral prednisolone administration. Because of the gradual improvement in renal function, hemodialysis was terminated after 53 sessions, however, the patient's chronic renal failure has persisted to date. In these two cases, the pathological findings supported the diagnosis of severe acute post-infectious glomerulonephritis with the characteristic crescentic and necrotizing glomerulonephritis with C3 deposition.

In patients with severe hypertension a search for a renal cause, particularly for a renal artery stenosis, needs to be undertaken with 24-hour blood pressure measurement, urinary examination, determination of renal function and duplex sonography of the kidneys.--Sympathetic hyperactivity, which is associated with an increased cardiovascular risk, may already be found in an early stage of renal diseases. There is evidence that administration of an ACE inhibitor or an angiotensin receptor antagonist (ARB) may induce a decrease of sympathetic hyperactivity as well as a reduced rate of adverse cardiovascular events in patients in renal failure.--In patients with renal disease and high proteinuria antihypertensive therapy with ACE-inhibitors or ARB delays the progression of chronic renal failure. Combined therapy of ACE-inhibitors plus ARB may reduce proteinuria more than that would be the case with either of these drugs alone. However, there is no evidence that combination of these two drugs improves renal function more than monotherapy.--Renal artery stenosis of > 70% should be treated by dilatation, if there is evidence of fibromuscular dysplasia. Dilatation and/or stent implantation in an atherosclerotic renal artery stenosis of > 70% should be performed if indicated by the patient's clinical state. i.e. severe hypertension has proved to be resistant to triple drug antihypertensive therapy or pulmonary edema has occurred frequently. Preservation of renal function by angioplasty of an atherosclerotic renal artery stenosis remains a challenge. However, exact criteria for such intervention need to be established. But so far there have not been adequate data from controlled prospective trials.

We investigated the clinical and photographic characteristics of uremic lung and review the associated literature, so as to improve the diagnostic and therapeutic abilities of uremic lung. The clinical symptoms and signs together with the photographic characteristics of the patient who was diagnosed as uremic lung complicated with pulmonary infection and congestive heart failure in our division were analysed and the associated literature was reviewed. The patient was admitted for the complaint of cough, expectoration and dyspnea. He was diagnosed as chronic renal failure with pulmonary infection and congestive heart failure. The symptoms alleviated after adequate hemodialysis and antibiotic therapy. However, mild dyspnea remained with photographic examination still showing consolidation in the lungs. The diagnosis of uremic lung was established after the exclusion of pulmonary infections of other pathogens and tumor. After 8-month maintenance hemodialysis, the pulmonary lesions were thoroughly absorbed. Uremic lung is a common complication of end-stage renal failure. The diagnosis is established after the exclusion of cardiac pulmonary edema, pulmonary infections and tumors. Sufficient hemodialysis is the most adequate treatment for uremic lung.

We report the perioperative management of a 55-year-old man with chronic renal failure requiring long-term hemodialysis, who underwent laparoscopic adrenalectomy for pheochromocytoma. He was pretreated with doxazosin, a calcium channel blocker and a beta-adrenoceptor antagonist to control blood pressure until surgery. His dry weight increased slowly from 57 kg to 58.5 kg for a month increasing the intravascular volume. Neither did the patient develop pulmonary edema nor congestive heart failure preoperatively. Tumor resection was successfully completed under general anesthesia. Although noraderenaline was required to keep adequate blood pressure during surgery and the first day of intensive care unit stay, there was no adverse event during perioperative period. The increasing intravascular volume before pheochromocytoma surgery in a patient on hemodialysis might make the perioperative management safer, although further study is required to determine the adequate level of increment in the preoperative dry weight.
