RESUMEN
BACKGROUND: Peritoneal dialysis (PD) is not frequently used in our setting. OBJECTIVE: To analyze the psychological factors involved in the choice of renal replacement therapy (RRT). MATERIAL AND METHODS: A prospective observational study of stable patients without cognitive or sensory deficits who were informed about RRT from January 2004 to July 2006 and agreed to participate. The patients were given and completed the Beck Depression Inventory and the Eysenck personality questionnaire. Clinical and sociodemographic data and RRT choice were recorded. End of follow-up: 2007/10/31. RESULTS: 44 patients were studied: age, 65.4 +/- 13.1 years, 48% male, 34% diabetic. When choosing RRT, 36% of patients had symptoms of depression. Neither depression symptoms nor personality traits were related to the choice of dialysis type. The youngest patients chose PD (41%). After a mean followup of 8 +/- 8 months, 70% of patients started RRT (68% haemodialysis [HD], 32% PD). None of the patients who chose HD changed their mind, but 3 of the 13 patients (23%) who chose PD finally commenced HD, usually in the context of a worsening of the disease. Half of the patients with depression symptoms when choosing PD and a third of the patients with higher levels of neuroticism changed their decision and finally opted for HD. CONCLUSIONS: When choosing RRT, the prevalence of depression symptoms is high. Neither depression nor personality traits influenced the initial choice of RRT, although these factors may be involved in subsequent changes to the decision.

According to previous reviews, hemoperitoneum episodes appear in 6.1-8.4% of the peritoneal dialysis patients, and they are severe in a 20% of them. Due to the absence of severe hemoperitoneum in our peritoneal dialysis program, we retrospectively reviewed hemoperitoneum non-related with abdominal surgery or catheter placing. We analyzed its incidence, etiology, prognostic and clinical outcome, as well as the possible effect of recurrent hemoperitoneum on peritoneal function. A total of 132 patients were treated in our centre during a period of 173 months. Mean age at the beginning of peritoneal dialysis was 59+/-17.1 years, 43.2% were females, and 22.8% of them were menstruating women. Twenty-two patients had at least one hemoperitoneum episode during follow-up, with an incidence of 17%. The mean time interval between the start of peritoneal dialysis and the first hemoperitoneum episode was 0.66+/-0.94 years (range: 0.01-3.20 years). 73% were women. Most cases (59%) were due to menstruation. Remarkably, all the menstruating women presented hemoperitoneum at least once with a high incidence of recurrent episodes. The other hemoperitoneum episodes were mainly of unknown etiology (32% of patients), being this one the main cause in males. We only observed two more cases: a male who presented hemoperitoneum related to dicumarinic overdose and a female who presented hemoperitoneum due to mesenteric ischemia. All the 22 patients had a favourable outcome, except for the woman with mesenteric ischemia, what represented an incidence of 4.5% of severe hemoperitoneum. No significant association was found between episodes of hemoperitoneum and aspirin treatment, dicumarinic treatment or the presence of coagulopathy. There was no association either between recurrent hemoperitoneum and the number of peritonitis episodes, peritoneal function or technique survival. In conclusion, hemoperitoneum is a common and usually benign problem in peritoneal dialysis patients, frequently due to retrograde menstruation, and no deleterious long-term effects were found in patients with recurrent hemoperitoneum.

BACKGROUND AND OBJECTIVE: Knowledge of the life-sustaining treatment preferences of the dialysis patients would be extremely helpful to substitute decision-makers and nephrologists in deciding whether to continue or stop a treatment. The population of the Mediterranean countries show this opinion with less frequency. The objective of this study is: 1) the knowledge of the patient's view for the advance directives; it may increase the likelihood to get the correct decisions of the staff when complications break the normal course of chronic dialysis, and 2) the statement of the advance directives. MATERIAL AND METHOD: We distributed 135 questionnaires to patients with chronic renal failure in dialysis treatment of the Sabadell's Hospital to explore demographic information about responders and not-responders and explore the rate of questionnaires was completed about the cardiopulmonary resuscitation, respirator, tube feeding and dialysis in case of coma, persistent vegetative state, severe dementia and terminal illness. We explore about the representative of patients and in case of not-responders about the cause to not answer. RESULTS: Sixty-four of 135 patients (47,8%) did not want cardiopulmonary resuscitation, respirator, tube feeding or dialysis in case of coma, persistent vegetative state, severe dementia or terminal illness. Compared with patients who wanted the treatments, those who did not were older (71,2 versus 62,2 years; p = 0.002). There was no difference in the other demographic questions, including sex (p=0.674), cause of kidney failure (p=0.815), comorbid conditions (p=0.824), and social status (language of questionnaire -0.155- and standard of education -0.288-). Advance care planning does not occur solely within the context of the physician-patient relationship; the respondents reported the representative in the family, essentially. The patients not-responders doesn t want to think in those situations and also they show doubt about the interpretation of their answers. CONCLUSIONS: near 50% patients in chronic dialysis want to stop certain treatments in case of resuscitation cardiopulmonary, coma, persistent vegetative state, severe dementia or terminal illness. The older patients want the limitation of treatments more frequently.

BACKGROUND: The incidence of chronic renal failure increase with the age. The selection of patient to dialysis has been increasing in spite of the high comorbidity. Moreover, in our clinical practice the aged patient is not contraindicated to dialysis. However, in the nephrology clinical practice not all the patients start the treatment with dialysis. OBJECTIVE The aim of our study has been to compare the characteristics of the patients who had not been dialyzed between the periods 1992-1995 and 2000-2003 to analyze the trend of the nephrology clinical practice. MATERIAL AND METHODS: Comparative study of the characteristics and the evolution of patients with chronic renal failure in stage V, (renal failure) not incorporated to dialysis in one hospital during four years between the periods the 1992-1995 ( period A) and 2000-2003 (period B). RESULTS: Start dialysis (period A versus period B): 116 patients, age 59.9+15.5 years vs. 229 patients, age 64.0+15.8 years (p<0.05). Non-dialysis (period A versus period B): 38 patients, age 77.5+9.3 years vs. 37 patients, age 81.7+6.2 years (p<0.01). Renal function: serum creatinina 7.4+2.4 mg/dl vs. 5.3+1.2 mg/dl (p<0.001), MDRD estimate glomerular filtration 6.9+2.4 mg/dl ml/min/1.73 m2 vs. 10.0+2.3 ml/min/1.73 m2 (p<0.001). Primary renal disease: unknown etiology 31.5 % vs. 24.3 %, nephroangiosclerosis 23.6 % vs. 32.4 %, diabetes 28.9 % vs. 21.6 %. Functional status: dependent patients 34.2 % vs 83.8 % (p<0.001). The principal reason for non-dialysis were: personal decision: 26.3 % vs. 35.1 %, dementia 15.8 % vs. 29.7 %, brief life expectancy because of serious co-existing diseases 13.1 % vs. 21.7 % and serious chronic illness with inability for themselves care 44.7 % vs. 13.1 %. Comorbid conditions: 2.3+1.0 vs. 3.0+1.5 (p<0.05). Survival: 55+168 days vs. 168+236 days (p<0.001). CONCLUSION: Most of the patients that don't begin dialysis are elderly together with a poor functional capacity and with more autonomy in their decisions. The identification of patients with renal failure (stage V) was detected early in the last period than in the following one. The conservative management of non-dialyzed uremic patients is a significative nephrology clinical practice due to more survival of those persons.

We report a case of a 49 year old man, diagnosed soon after the outcome of casual proteinuria, of AA-type amyloidosis in relation to small and medium vessel cutaneous vasculitis without systemic involvement. This combination is a rare entity and only two cases of cutaneous hypersensibility vasculitis complicated with AA-type amyloidosis had been reported. We describe the results of the use of several immunosuppressive drugs during four years follow up with temporally total remission of the disease.

Although drug induced interstitial nephritis is a relatively common cause of renal failure,granulomatous forms remain a rare condition. The development of a chronic granulomatous interstitial nephritis due to allopurinol is exceptional, only three cases have been described previously. We report on a patient who presented a granulomatous interstitial nephritis after 10 years of allopurinol administration (300 mg/day). At diagnosis, he had end stage renal disease and dialysis treatment was needed. Two months after drug withdrawal and on corticoid treatment a slow recovery of renal function was observed, allowing the interruption of dialysis. Two years after, the creatinine clearance is 23 ml/min,being dialysis free. We discuss the differential diagnosis of granulomatous interstitial nephritis and its rare association with allopurinol treatment.

UNLABELLED: The voluntary discontinuation of dialysis by patients is a common mode of death in dialysis programmes. Unfortunately the Spanish experience has not been related in the nephrological literature. Initiation of, and withdrawal from, dialysis pose ethical questions for medicine in the 21st century. The dialysis population is aging and they have multiple medical problems. The choice may be between prolongation of quantity or quality of life. We evaluated a protocol for initiation of dialysis in patients with end stage renal failure and their subsequent withdrawal. We determined the factors predicting withdrawal of dialysis and revised the protocol to take account of these. We carried out an opinion poll of doctors and nurses about the effectiveness of the protocol. We studied prospectively the reasons for death of patients in the last seven years. RESULTS: Thirty patients were withdrawn from dialysis out of 116 who died during treatment by hemodialysis or continuous ambulatory peritoneal dialysis (CAPD) in the last seven years. Vascular nephropathy is the principal disease predicting withdrawal from dialysis; the main precipitating cause is mental incapacity. The availability of a protocol for withdrawal of dialysis is well received by doctors and nurses and it engenders moral and legal calm when facing difficult decisions. Twenty-six per cent of deaths on regular dialysis are the result of withdrawal of treatment.

BACKGROUND: The adequate control of phosphataemia is of major importance in end-stage renal disease patients on maintenance dialysis. Recently, lanthanum carbonate (LC) has been added to the phosphate binder armamentarium. To our knowledge, no studies have yet evaluated the usefulness of this drug in uncontrolled hyperphosphataemic patients. METHODS: This was a 6-month prospective observational study. Patients on chronic hemodialysis who had previously failed to achieve serum phosphate control were enrolled. Thirty-four patients (i.e. 11% out of 305 from three dialysis units) met the inclusion criteria. Lanthanum carbonate was introduced and titrated to achieve serum phosphate control, according to the KDOQI guidelines. Clinical targets, gastrointestinal symptoms, and patients' satisfaction with therapy were assessed at baseline and after 6 months. RESULTS: Eight patients (23.5%) were withdrawn from the study due to side effects. In the remaining patients, serum phosphate level significantly decreased from 5.8 to 4.4 mg/dl and calcium-phosphate product also decreased significantly from 55.6 to 41.8 mg(2)/dl(2). The average number of all phosphate binder tablets taken per day was reduced from 6.7 to 4.7. Evaluation scores of dyspeptic symptoms and of patient's satisfaction with therapy also improved: from 7.5 to 5.3 and from 6.6 to 8.1, respectively. CONCLUSIONS: The introduction of LC improved serum phosphate control in over 70% of these "difficult patients". A lower pill burden was also obtained, which might help to simplify treatment and increase patients' compliance. Dyspeptic symptoms and overall satisfaction with treatment also improved.

Association between lipids and renal disease has been reported recently. Its pathogenic mechanisms remain unknown. The aims of this study were to establish: (1) if a cholesterol-rich diet, alone or associated with nephrectomy, produces nephropathy; and (2) if a treatment with omega-3 polyunsaturated fatty acids (PUFA) reduces glomerulosclerotic lesions. Sixty Sprague-Dawley rats were randomized in two different groups: (A) sham operated rats and (B) uninephrectomized rats. Rats in both groups were divided into three subgroups (A1-3, B1-3) according to the diet they were fed: normal chow diet, cholesterol-rich diet (4.5%) or cholesterol-rich diet supplemented with omega-3 PUFA. Twenty weeks later, serum creatinine, creatinine clearance, serum cholesterol, triglycerides, albumin, proteinuria, mesangial cell score and focal glomerulosclerosis were assessed. Results showed that a cholesterol-rich diet significantly increased serum cholesterol, proteinuria and glomerular lesions and decreased creatinine clearance, especially in nephrectomized rats. Glomerular lesions, serum cholesterol and proteinuria ameliorated when cholesterol-rich diet was supplemented with PUFA. Hypertension was noticed only in nephrectomized rats following a normal chow diet. Simple correlation analysis showed that glomerulosclerosis correlated with renal weight, blood creatinine, cholesterol and proteinuria. In spite of some significant differences in urinary prostaglandins, no correlation with glomerular lesions was found. Multiple logistic regression analysis showed that cholesterol and proteinuria were independent risk factors for induction of glomerular sclerosis. In conclusion, a diet rich in cholesterol induces glomerulosclerosis, especially if it is associated with unilateral nephrectomy. Omega-3 PUFA administration reduces serum cholesterol, proteinuria and glomerular injury.
