A total of 1038 adult patients with dialysis-dependent renal failure were treated at this centre between 1981 and 1991. Data on racial origin and primary renal diagnosis have been analysed in order to determine the prevalence of end-stage renal failure (ESRF) and its causes. Compared with Caucasians there was a greater proportion of Asians (P < 0.001) and Blacks (P < 0.001) with ESRF. The relative risk of ESRF in Asians compared with Caucasians was 1.76 (95% CI 1.46-2.10) and for Blacks 1.76 (95% CI 1.39-2.2). Hypertension/renal vascular disease and systemic lupus erythematosus were more frequent causes of ESRF in Blacks than in Caucasians (P < 0.005). Hypertension/vascular disease and tuberculosis were more frequent causes of ESRF in Asians than Caucasians (P < 0.005) respectively. Diabetes mellitus appeared to be more common as a cause of ESRF in Blacks than Asians or Caucasians (0.1 > P > 0.05). Adult polycystic disease was significantly less common in Asians compared to Caucasians and Blacks (P < 0.05). The prevalence of ESRF in Asians and Blacks in the West Midlands appears to be greater than that of Caucasians, mostly as a consequence of hypertension/vascular disease and to a lesser extent of systemic lupus erythematosus in Blacks and of tuberculosis in Asians. If these data are confirmed by prospective study then they have implications for service provision.

To compare the therapeutic effect of 15-deoxyspergualin with that of methylprednisolone on advanced lupus nephropathy of New Zealand black/white F1 hybrid (B/W) mice, and also to study the possible synergistic effect of both drugs, B/W mice were heminephrectomized at 32 weeks of age, and were divided into six groups. Each group of mice was treated with 50 microliters phosphate-buffered saline (PBS), 3 mg/kg methylprednisolone, 20 mg methylprednisolone, 0.6 mg DSP, 6 mg DSP, or with 3 mg methylprednisolone plus 0.6 mg DSP, s.c., four times per week for 8 weeks. Urine and blood samples (by tail vein venipuncture), as well as renal tissue specimens, were taken at 32 and 40 weeks of age. The degree of proteinuria, and serum anti-DNA activity (by ELISA) were determined. Renal specimens were evaluated with light- and immunofluorescence (C3)-microscopy, the degree of pathological changes being semi-quantitated and expressed as total light-microscopy (LM) and immunofluorescence (IF) scores. The survival rate at 40 weeks of age was significantly elevated in 0.6 mg DSP, 6 mg DSP, and methylprednisolone + DSP groups of mice compared with the control group. The appearance rate of significant post-treatment proteinuria was comparable among all groups. The difference (post-treatment titre--pretreatment titre) of serum anti-DNA activity in the 6 mg DSP and methylprednisolone + DSP groups were significantly less, while that of the 3 mg methylprednisolone group was greater compared with the control level. As for the total LM score, the levels significantly decreased in the 6 mg DSP, methylprednisolone + DSP and 3 mg methylprednisolone groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Only 15 cases of any etiology of Neisseria meningitidis peritonitis have been reported in the world literature since the first case in 1917. We report the first case in a continuous ambulatory peritoneal dialysis (CAPD) patient presenting with abdominal pain and cloudy peritoneal dialysis fluid. A lumbar puncture was normal. The patient died despite therapy with ceftriaxone. Autopsy confirmed this was a case of primary N. meningitidis peritonitis. Of the 15 cases of N. meningitidis reported as a cause of peritonitis, 9 patients were less than age 35 with no underlying diseases. Five cases were associated with cirrhosis or alcohol abuse. Two cases were associated with meningitis, and 1 patient was on steroid therapy for systemic lupus erythematosus. Nine of 15 patients recovered. In conclusion, N. meningitidis should be considered as another rare cause of peritonitis in patients on CAPD.

Serum procollagen type I carboxyterminal propeptide (PICP) has been shown to be a useful marker of bone formation in patients undergoing haemodialysis. However, PICP levels has not been evaluated in depth in patients maintained on continuous ambulatory peritoneal dialysis (CAPD). Therefore serum and dialysate levels of PICP, its peritoneal clearance (Clp), mass transfer (MTp), and its possible relationship with osteocalcin, parathyroid hormone (PTH), and bone histomorphometry were studied in a group of CAPD patients. Serum PICP was just above the normal range with significant amounts detected in the dialysate but no correlations were found between levels of serum PICP, dialysate PICP, and Clp-PICP. One patient with systemic lupus and osteitis fibrosa had extraordinarily high serum and dialysate levels of PICP. The patient later developed sclerosing peritonitis. No associations were seen between serum PICP and Clp-PICP and any of the 18 bone histomorphometric parameters evaluated. Dialysate level of PICP correlated negatively with mineral appositional rate (r = -0.62, P < 0.01) and mineralization lag time (r = 0.64, P < 0.01). MTp-PICP correlated positively with mineral appositional rate (r = 0.65, P < 0.01). Serum osteocalcin and serum PTH levels did not correlate to serum, dialysate, Clp or MTp measurements of PICP. These results suggest that measurements of PICP in CAPD patients do not give substantial information as an non-invasive marker of bone histology.

The purpose of our study was to compare the incidence of peritonitis between continuous ambulatory peritoneal dialysis (CAPD) treatment (Group I) and automated peritoneal dialysis (APD) treatment (Group II) taking into account the same population. We compared 20 patients with a follow-up of 215 patient-months on CAPD and 252 patient-months on APD. Demographic data, diagnosis, peritoneal equilibration test (PET) results, adequacy, and peritonitis rate were analyzed. Diagnoses included glomerulopathy 35%, autosomal dominant polycystic kidney disease (ADPKD) 20%, Type II diabetes 10%, systemic lupus erythematosus 5%, interstitial nephritis 5%, nephrolitiasis 5%, and unknown 20%. PET results showed that the group consisted of 30% high transporters, 45% high-average transporters, and 25% low-average transporters. Kt/V for Group I was 1.3 +/- 0.3, and for Group II, 1.83 +/- 0.48. Creatinine clearance for Group I was 43.64 +/- 7.31 L/week/1.73 m2, and for Group II, 52.42 +/- 13.47 L/week/1.73 m2. Group I presented a peritonitis rate of 8.3 episodes/patient-month, and Group II presented a rate of 18.9 episodes/patient-month. Gram-positive organisms were responsible for 49.8% of episodes of peritonitis in Group I (S. aureus 26.6%, S. epidermidis 16.6%, others 10%) and 83% of peritonitis episodes in Group II (S. epidermidis 46.6%, S. aureus 20%). Gram-negative organisms were responsible for 16.5% of episodes of peritonitis in Group I. No gram-negative peritonitis was seen in Group II. APD patients developed two cases of candida peritonitis. Our preliminary results show that Group II exhibited a decrease in peritonitis rate while achieving better adequacy. In CAPD and APD peritonitis, gram-positive organisms predominated. In APD, we observed an increase in S. epidermidis incidence. No gram-negative organisms were observed in APD. It seems that APD is a safer treatment owing to the lower peritonitis incidence.

Immunosuppressive treatment is a critical procedure in dialysis patients, in whom an increased risk of infection is already present. Haemodialytic treatment increases the patient's susceptibility to bacterial infection, mainly by impairing polymorphonuclear leukocyte phagocytosis, but it can also restore the patient's immunological defences by improving the T-cell function, which is reduced by pre-dialysis uraemia. Patients on dialysis usually continue the immunosuppressive treatment that had been established for the illness that caused their renal failure [e.g. systemic lupus erythematosus (SLE) or renal vasculitis]. Less frequently, patients on dialysis need immunosuppression for immunological or inflammatory diseases that appear 'de novo' after initiation of dialysis. SLE and antineutrophil cytoplasmic antibody (ANCA)-related vasculitides are immunological illnesses that frequently cause end-stage renal failure (ESRF). A reduction in serological and/or clinical activity is usually observed in SLE patients after they reach ESRF, but a similar or increased frequency of extrarenal relapse episodes in lupus patients after the beginning of the dialysis, compared with the pre-dialysis period, has also been described. Frequency of relapse episodes in patients on dialysis treatment for ANCA-related vasculitides varies from 10 to 30% per patient/year in different reports, and it is higher than the frequency of relapses after renal transplantation; anti-rejection therapy seems to be the most likely protective factor in these conditions. The treatment of relapse episodes in SLE or ANCA vasculitis in dialysis-dependent patients is usually not different from treatment of relapses in patients with dialysis-independent renal function. However, the risk of severe infection caused by immunosuppressive treatment is relevantly higher in dialysis patients. Furthermore, there is a lack of prospective controlled studies indicating the optimal management of immunosuppressive protocols in dialysis patients. A particularly careful assessment of the patient's risks and benefits is necessary in deciding how long immunosuppressive treatment should last after acute or rapidly progressive renal damage, that should require dialysis treatment, in patients with SLE or ANCA vasculitis. In the above conditions, the risks of prolonging immunosuppressive treatment must be balanced against the relatively good prognosis offered to these patients by dialysis and renal transplantation. In a retrospective review of 24 patients receiving long-term steroid therapy (>3 months) in our dialysis unit in the past 5 years, we found relevant clinical differences in the patients receiving steroid treatment compared with 24 controls. Steroid-treated patients showed less favourable nutritional conditions, with lower serum albumin and body mass index vs non-steroid-treated patients; moreover, C-reactive protein values were persistently higher in the steroid-treated group. Steroid treatment in these patients was usually performed at the beginning of regular dialysis, as a continuation of the treatment that started before the initiation of dialysis. Only two patients, who needed a prolonged low-dose steroidal treatment to control a malnutrition-inflammation-atherosclerosis (MIA) syndrome, started steroids many years after beginning dialysis. Steroid treatment was effective in improving the nutritional condition and inflammatory symptoms in these two patients after all conventional measures had failed.

Twenty-six patients, who received plasmapheresis (PP) either alone or synchronized with cyclophosphamide (IV-CYC/PP), are retrospectively reviewed from Medline searches and personal experience from 1976 to 2002. Patients with central nervous system neuropsychiatric systemic lupus erythematosus (CNS-NPSLE) were evaluated according to the American College of Rheumatology (ACR) case definitions of 1999. Eleven of the patients were under the age of 21 years (range 7-21 years), highlighting the need for an aggressive treatment option for young patients who are refractory to other treatments. After treatment with PP or IV-CYC/PP, 74% of patients improved, 13% stabilized, and 13% progressed. Major side-effects occurred from central line placement rather than immunomodulation from PP itself Step-down therapies are needed to supplement IV-CYC/PP once improvement has reached a plateau. Newer combinations of PP and intravenous immunoglobulin (IVIg), human stem cell transplant (HSCT) and rituximab (RTX) should be considered in the future. In the absence of randomized controlled trials (RCT), experienced clinicians must weigh risk, benefit, and cost profiles in considering the treatment of severe CNS-NPSLE with PP.

In the last 30 years, several studies have documented the effect of plamapheresis and immunoadsorption in eliminating pathogenic autoantibodies (AB) and immune complexes (IC) from circulation of patients with systemic lupus erythematosus (SLE). However, these extracorporeal therapies are still not accepted as first line options, which may be because of existing controlled studies failing to confirm any obvious benefit. Immunoadsorption offers some advantages compared with plasmapheresis, but until today only the avoidance of any substitution fluids has really been used. The new therapeutic options given by immunoadsorbers--a continuous application in acute disease states or chronic use instead of immunosuppressive drugs--have still to be evaluated in systemic autoimmune diseases. To date published studies of immunoadsorption in patients with SLE reveal good efficacy in a majority of patients combined with excellent biocompatibility. Randomized controlled trials are mandatory to give continued support to the therapeutic opportunities offered only by immunoadsorption; the limited number of patients suitable for this therapy necessitates multicentric cooperation.

Cellsorba is a leukocyte removal filter developed by Asahi Medical Co., which adsorbs white blood cells through the perfusion of peripheral blood by means of simple extracorporeal circulation. Leukocytapheresis (LCAP) therapy using the Cellsorba column has been reported to show therapeutic effects for many autoimmune related and inflammatory diseases, such as inflammatory bowel disease, rheumatoid arthritis, systemic lupus erythematosus, neurologic disease, and so on. At present, Cellsorba is listed as a medical device covered by the Japanese national health insurance system for the treatment of active ulcerative colitis (UC) in Japan, and contributes to the improvement of quality of life in many UC patients. This paper reviews the use of Cellsorba and introduces several reports on therapeutic results.

Liposorber is a column used for plasma purification that adsorbs low-density lipoproteins with high selectivity, while Selesorb is a column that selectively adsorbs anti-DNA antibodies, anticardiolipin antibodies, and immune complexes. Both columns are packed with carriers, where a dextran sulfate ligand is bound to porous cellulose beads. Liposorber is used to treat familial hypercholesterolemia (FH), peripheral arterial disease (PAD), and focal segmental glomerulosclerosis (FGS): Selesorb is used to treat systemic lupus erythematosus (SLE). Treatment utilizing both columns is being used effectively in patients with refractory disease that is resistant to pharmacotherapy.
