[Hypokalemic nephropathy from the chronic use of diuretics and laxatives].

The cases of two women with morphologically proved hypokalemic nephropathy related to chronic use of diuretics and purgatives are reported. The disease has been detected because of reduced urine quantity, increase of body mass and edema. The serum protein level is low.

[Rapidly progressing glomerulonephritis developing against a background of idiopathic nephrotic syndrome].

A case is presented of a woman with idiopathic nephrotic syndrome--mesangioproliferative glomerulonephritis who after a 7-year therapeutic remission developed a rapidly progressing (semilunar) glomerulonephritis with a severe nephrotic syndrome, arterial hypertension, anemia, renal failure. The patient was not influenced by the treatment with ordinary doses of glucocorticosteroids and temporarily improved by the combined "pulse" methylprednisolone, immunosuppressive and heparin treatment. The possible pathogenetic mechanisms which may have played a role in the transition of the idiopathic nephrotic syndrome into a rapidly progressing glomerulonephritis are discussed.

[An acute recurrence of focal-segmental glomerulosclerosis in a kidney transplanted from mother to son with a rapid decline in kidney function].

A case is presented of a 19-year-old man suffering from focal-segmental glomerulosclerosis with terminal chronic renal failure to whom a kidney taken from his mother was transplanted. There was high blood-group and tissue compatibility between mother and son. The initial result was good, the transplanted kidney functioned well-diuresis of 3300 ml with high proteinuria.

[Clinical, laboratory and morphological characteristics of mesangioproliferative glomerulonephritis].

The mesangioproliferative glomerulonephritis (MPGN) is the most frequent morphological type of primary glomerulonephritis and it was found in 42.7% of the patients studied. The MPGN is not a single nosologic entity which is proved by the immunofluorescent findings, clinical and laboratory characteristics.

[Acute recurrence of focal-segmental glomerulosclerosis in the kidney transplanted from mother to son with rapidly progressing failure of renal function].

After a brief survey, stressing upon the high susceptibility of the focal-segmental glomerulosclerosis to recurrences in transplated kidney, the authors announced one of their own observations on a youth, aged 19, that was transplated a kidney from a living donor--his mother. The basic disease in the acceptor led to chroniodialysis after 20 months of the first clinical signs. In spite of the high diuresis, that was observed after the transplantation of the maternal kidney, proteinuria persisted as early as the first days after the transplantation, creatinine did not reach the normal values and after I month chroniodialysis was again included, followed by detransplantation.

[Acute papillary necrosis in transplanted kidney].

After a short literature survey, indicating the rarity of acute papillary necrosis in transplanted kidneys, the authors reported one of their patients, aged 32, with transplanted dead body kidney from a male, aged 30, with blood group compatibility and compatibility of two antigens in locus A. Two hemodialysis were necessiated because of acute tubular necrosis in the transplant. After the second one, performed 10 days after the transplantation, the patient felt very strong pains in the region of the transplant, edema around it and hypovolemic shock.

[Acute interstitial nephritis with iridocyclitis].

One case with acute interstitial nephritis with undistinguished etiology, accompanied by iridocyclitis is described. Recently, numerous communications about similar cases have been reported which justify the differentiation of the syndrome "interstitial nephritis-iridocyclitis" among the acute interstitial nephritis. The case is of certain interest because of some characteristics: involvement of liver in the morbid process, immunemorphological finding from that described by other authors.

[Case of Fabry's disease].

A patient is described, admitted to the clinic on the occasion of proteinuria, edemas and arterial hypertension. The clinical and paraclinical data formed the picture of a renal involvement of mainly glomerular type with proteinuria to 5 gr%0, nonselective type, edemas, hypertension and data of chronic renal insufficiency I degree (serum creatinine to 3.8%, blood urea to 112 mg%).

[Acute papillary necrosis in the transplanted kidney].

After a brief literature survey revealing the rarity of the papillary necrosis in transplanted kidneys, the authors report the case of one of their patients, aged 32, transplanted a corpse kidney of a 30-year old male with blood-group compatibility and with coincidence of the two antigens in locus A. Regardless of the increased diuresis of the patient to 3-4 1 within 24 hours, its nitrogen bodies persisted their elevation, necessitating two dialysis. After the second dialysis performed on the tenth day after the transplantation, the patient had very strong pains in the transplantation region, edema around it and a hypovolemic shock.

[Benign course of focal-segmental glomerulonephritis due to antibodies to the glomerular basement membrane].

The authors describe a patient with focal-segmental glomerulonephritis with a benign progress, induced by antibodies to glomerular basement membrane. Clinically the disease advanced in the course of 10 years with painless macroscopic hematuria and persisting microscopic hematuria during the intervals. Histologically, a focal-segmental glomerulonephritis was established, with crescents in certain glomeruli and immunomorphologically with linear depositis of IgG, C3 and febrin.
