Rapid resolution of EPO-induced pure red cell aplasia after a course of immunoadsorption therapy using protein A columns.

Pure red cell aplasia (PRCA) is a rare, but important, complication of erythropoietin (EPO) replacement therapy in patients with renal disease. There is no consensus about the best way to treat this condition; however, recent reports indicated that immunosuppressive therapy is beneficial. We report a patient with EPO-induced PRCA treated with a regimen initially designed for antifactor VIII antibodies in patients with hemophilia. This regimen consists of immunoadsorption therapy using protein A columns, followed by oral prednisolone and single bolus infusions of intravenous immunoglobulin G and cyclophosphamide. Shortly after the course, a swift and rapid increase in reticulocyte count was evident; the patient became transfusion independent and has remained so during 2 years of follow-up. By means of this report, we wish to encourage others to consider this option when first-line treatments fail.

Quality of life in the African American Study of Kidney Disease and Hypertension: effects of blood pressure management.

BACKGROUND: The African American Study of Kidney Disease and Hypertension was a multicenter trial comparing the effects of 2 levels of blood pressure control (usual or low goal) and initial therapy with metoprolol, ramipril, or amlodipine. We examined effects of treatment-group assignment on health-related quality of life (HRQOL) measures and reported symptoms during 4 years of follow-up. METHODS: HRQOL was assessed at baseline and annually by using the Medical Outcomes Study 36-Item Short Form (SF-36) and a symptom checklist. Using a 2-slope model, treatment effects were evaluated for change from baseline to year 1 and for average change during the first 4 years of follow-up. RESULTS: A total of 1,094 participants were randomly assigned. Average age was 55 years, 61% were men, and the mean of the first glomerular filtration rate in the study was 46 mL/min/1.73 m2 (0.76 mL/s). No significant differences in HRQOL were seen between the low- and usual-blood-pressure groups. Reported side effects also were similar between blood-pressure groups. Mean Physical Health Component (PHC) and Mental Health Component (MHC) scores had a significantly smaller decrease in the ramipril than metoprolol group in both the initial period from baseline to year 1 (PHC, 2.08 +/- 0.56; MHC, 1.89 +/- 0.62) and during the first 4 years of follow-up (PHC, 1.60 +/- 0.44; MHC, 1.48 +/- 0.48). The MHC also had a slightly smaller decrease during the first 4 years in the ramipril group than amlodipine group (1.20 +/- 0.61). CONCLUSION: Aggressive blood pressure control is well tolerated in African Americans with hypertensive kidney disease, measured by using the SF-36 and reported symptoms. The clinical significance of smaller decreases in PHC and MHC scores in the ramipril compared with metoprolol group is not clear.

[Primary oxalosis. report of a case with radiologic-pathologic-anatomical correlation and review of the literature (author's transl)].

The radiological changes in a patient with endogenous oxalosis are correlated with their pathological and anatomical counterparts. These involve particulary the kidneys (nephrolithiasis, calcium oxalate nephrosis with scarring), the skeleton (combination of renal osteodystrophy, secondary hyperparathyroidism and oxalate deposition), and soft tissues (generalised oxalate deposition). The pathological aspects described in the literature are mentioned and possible forms of treatment are stressed.

Epinephrine renal venography.

Experience with the use of epinephrine renal venography in 60 patients with various renal disease is reviewed. The technique offers an important supplement to selective arteriography. It is of particular value in the diagnosis of avascular infiltrative tumors of the renal parenchyma and pelvis. Further, it is of value in the detailed demonstration of renal vein thrombosis and in seeking the cause of unexplained gross hematuria. It can also aid in evaluating expansile avascular renal masses and renal parenchymal disease. The authors found only a relatively low value for epinephrine renal venography in the diagnosis of hypervascular renal tumors and the early detection of venous extension of hypernephromas.

[BENEFIT Kidney--significance of a nephrology screening at intervention outset and therapy success].

BACKGROUND AND OBJECTIVE: Early specialist care of patients with renal disease, including timely and planned onset of dialysis, determine the course of the disease, quality of life, hospitalization and life expectancy. A multi-centre enquiry by standardized questionnaire was undertaken to define and analyse medical care of newly dialysis-requiring patients. PATIENTS AND METHODS: Data on 551 patients in five different regions of Germany who for the first time required renal replacement treatment were prospectively collected between July 2002 and March 2003. Documentation of history, clinical findings and biochemical tests was done on consecutive patients with a standardized questionnaire, until the desired number of cases was reached. RESULTS: The mean age of the patients (55.4% males) was 64.8 years. 30.7% had diabetes mellitus, 22.3% arterial hypertension/nephrosclerosis and 16.9% glomerulonephritis/vasculitis. Early predominantly nephrological care had been undertaken in 38.7% of patients. 59.0% were cared for almost exclusively by their general practitioner until the time when dialysis was started. 229 patients (41.6%) were referred to specialist (nephrologists) only when dialysis had become necessary. The onset of dialysis was at the right time in only 50.5% of this group. Comparing the care given by nephrologists with that by general practitioners, elective (i.e. planned) dialysis was begun in 81.0% vs. 48.0% (p<0.05). Hospitalization in the two groups was 54.5% vs. 83.7% (p<0.05), the duration of hospital stay 11.4 vs. 17.4 days (p<0.05). CONCLUSION: Fewer than 40% of patients with chronic renal disease in preterminal renal failure (stage IV) were under the care of nephrologists. The lower the degree of nephrological care the more frequent was there a delay in the onset of dialysis treatment. The incidence and the duration of hospital stay was longer. Structured treatment pathways and incentives need to be formulated to reduce the incidence of wrong or substandard treatment of patients with impaired renal function.

[Ultrasound in diffuse renal parenchymal disease (author's transl)].

Ultrasound examinations were compared with histopathological findings in 22 patients with diffuse renal parenchymal disease (glomerulonephritis, interstitial nephritis, glomerulosclerosis). The echogenicity of the renal parenchyma was graded by comparing it with the echogenicity of the liver, the spleen and the renal sinus and correlated with glomerular and interstitial findings. There was a direct correlation between echo intensity of the renal parenchyma and severity of renal parenchyma and severity of renal interstitial disease. Glomerular changes intensified the echogenicity of the parenchyma, but grading was not possible. Ultrasound is capable of documenting the course of disease and recognizing complications.
