[Renal disease with glomerular involvement during Brucella infection (author's transl)].

Renal involvement during Brucella infections has been known for several years, and its real frequency appears to be higher than initially suspected. This case report deals with a patient with positive blood cultures and seroagglutination to Brucella mellitensis who presented transitory renal failure, proteinuria, and macroscopic hematuria. Renal histopathology disclosed the existence of acute tubular necrosis, and the immunofluorescence study revealed the presence of mesangial deposits of immunoglobulins and complement. Electron microscopy demonstrated the presence of electron-dense paramesangial deposits. These data suggest that immunological mechanisms are implicated in the glomerular involvement of Brucella infections.

[Mixed essential cryoglobulinemia. Report of five cases (author's transl)].

Cryoglobulins are serum immunoglobulins which precipitate in the cold and redissolve on warming at 37 degrees C. According to its immunochemical composition three different types have been described. Cryoglobulins have been reported associated with hematologic disorders, systemic diseases, infectious conditions, and diseases of the liver and kidneys. There is also an idiopathic variant called essential cryoglobulinemia. Five patients (four males) with mixed essential cryoglobulinemia are reported. Common clinical manifestations included fever, articular symptoms, purpura, glomerulonephritis, Raynaud's phenomenon, erythematomacular cutaneous eruption, polyneuritis and abdominal pain. Serum activity of rheumatoid factor has been detected in three cases; in other three decreased levels of serum complement have been found. Serum HBsAg was negative in four cases (passive hemagglutination technique). It is possible that all cases of mixed essential cryoglobulinemia may correspond to bacterial, viral or fungal occult infections.

[Nephrotic syndrome and unilateral thrombosis of the renal vein. Acute renal failure and disturbances of the hemostasis (author's transl)].

The association of nephrotic syndrome and renal vein thrombosis has been increasingly reported in the literature due to the use of modern complementary explorative techniques. The incidence of renal vein thrombosis in the nephrotic syndrome varies according to the different authors. The pathogenesis of this association has been widely discussed and even though renal vein thrombosis has formerly been considered as one more cause of nephrotic syndrome, there are at present numerous arguments supporting the opposite thesis. A case of nephrotic syndrome and unilateral thrombosis of the renal vein in a patient with primitive extramembranous glomerulonephritis is reported. Blood coagulation studies revealed an initial hyperfibrinogenemia and a persistent decrease of factors V, VII, and X, with low rates of prothrombin. A thrombectomy was carried out, but the patient presented a Gram-negative sepsis without hypotension in the immediate postoperative period. As a consequence an acute renal failure developed and hemodyalisis was necessary for 2 months. The pathogenesis of both conditions are discussed.
