[Angiopathy in a case of primary oxalosis combined with familial spherocytosis (author's transl)].

An 18-year-old female with primary oxalosis, seen first when she was in advanced renal failure, developed a severe necrotizing angiopathy which began after a rapid decrease in renal function requiring chronic dialysis. Because of the severe angiopathy the preliminary diagnosis of an acute autoimmune vasculitis had been made. The correct diagnosis was revealed by renal biopsy and a renal transplantation performed. Soon after severe oxalosis led to failure of the renal transplant and death. The patient had also had familial spherocytosis, inherited from her father, while the oxalosis had been inherited from her mother. It is suggested that early transplantation at the onset of renal failure, as long as the blood oxalate level is still tolerably low, may give better results than have so far been reported.

[Long-time observation of a case of retroperitoneal fibrosis with Klinefelter's syndrome (author's transl)].

The etiology of retroperitoneal fibrosis still is largely unknown. Autoimmunologic mechanisms, traumata, systemic diseases, and drugs have been discussed as possible etiologic factors. The presented case was found to have a Klinefelter's syndrome besides retroperitoneal fibrosis. We do not believe that there is a relation between the two diseases. The retroperitoneal fibrosis of this case responded well to glucocorticosteroid therapy and the severly reduced renal function became normal.

[The use of photon absorptiometry in renal osteodystrophy (author's transl)].

In 58 patients with end-stage renal failure before commencement of regular hemodialyses treatment (RTD) and 58 patients under RTD bone mineral content (BMC) was determined by the use of the photon absorptiometry. Further the effect of a treatment with bitamin D3 and 5,6-trans-25-OH-vitamin D3 on BMC was studied. There existed a negative correlation between the duration of chronic renal failure or of RDT as well as of the serum parathyroid hormone level to BMC. No correlation was found between BMC and serum calcium level. During a 14 months-course treatment with vitamin D3 or 5,6-trans-25-OH-vitamin D3 BMC increased. The method of photon absorptiometry presented itself as an easy and well reproducible technique for routine examinations.

Renal disease in pregnancy.

Renal biopsy was obtained in 11 primiparous and 9 multiparous patients with severe pre-eclampsia. The large number of patients with renal disease allowed for single-case evaluation. Eclamptic convulsions and fetal deaths were observed in association with renal disease without foci of additional primary glomerular endotheliosis. The data indicate that pregnancy can exacerbate renal disease and allow for early diagnosis. Fluorescence angiography revealed changes in patients in whom the optic fundi were normal. Tissues of glomerulonephritis stained by immune fluorescence against immunoglobulins and on occasion against human fibrinogen. Primary endotheliosis and nephrosclerosis stained against fibrinogen only. There was no pattern of laboratory data to make the differential diagnosis between primary endotheliosis and various forms of renal disease. Fibrinogen breakdown products were inconsistently increased in contrast to fibrin monomer formation, which was increased regardless of the underlying morphology. It is our feeling that renal biopsy with subsequent pathologic classification is the only technique we have at present which provides relevant information on the effect of renal disease on pregnancy and vice versa.

Malignant nephrosclerosis during pregnancy and in the postpartum period (the uremic hemolytic syndrome).

Histologic, immunohistologic, and ultrastructural features are presented of two cases with malignant nephrosclerosis during pregnancy. Primary malignant nephrosclerosis emerges as a clinical entity which can be distinguished from toxemia of pregnancy in the midtrimester and post partum. The first description of malignant nephrosclerosis dates from 40 years ago, but only a few cases were reported associated with pregnancy. Although disseminated intravascular coagulation seems involved, the morphology is different from that of toxemia. Malignant nephrosclerosis reveals a close similarity to the hemolytic uremic syndrome. Early diagnosis by renal biopsy and proper treatment may prevent a lethal outcome due to progressive failure.

[Familial hemolytic anemia and terminal renal failure (author's transl)].

We report about a patient with corpuscular hemolytic anemia and chronic glomerulonephritis in the state of terminal renal failure. The hematocrit decreased to 11% gradually with the progression of uremia. The hematological studies revealed the typical signs of hemolytic anemia. We found a splenic destruction of 51-Cr labelled red cells combined with an extremely short red cell life of 7 days. After splenectomy hematocrit improved to 32%. A complete normalisation could not be expected because of the chronic renal failure leading to anemia itself.
