The focal tubulo-interstitial lesions (FTIL) described in the present paper appear as short segments of tubules showing epithelial degeneration, necrosis and desquamation. The foci are surrounded by mononuclear cells, among which lymphocytes are most numerous. They infiltrate through the damaged tubular basement membranes and may thus be located between epithelial cells and in the tubular lumen. Older lesions show focal tubular atrophy with thickened basement membranes together with focal interstitial fibrosis and lymphocytic infiltrates. The overall prevalence of this type of lesion in a consecutive renal biopsy series was 36%. It was not detected in 24 biopsies from patients without renal disease. The frequency of FTIL was high in acute renal failure due to hemolysis, shock etc. or to the action of drugs, as well as in some types of glomerulonephritis (membranous, membrano-proliferative, SLE). Tubular immunoglobulins were not demonstrated in 38 biopsies with FTIL. The pathogenesis and possible consequence of the lesions are still unclear, but it is suggested that they may in some situations contribute to the nephron atrophy in chronic renal disease.

We report here, a patient of systemic lupus erythematosus (SLE) with severe fibrinoid necrosis in the afferent arteriole of the glomerulus, in whom antiphospholipid antibody might have contributed to the pathogenesis. A 24-year-old female who was suffering from severe anemia with fragmented red blood cells, acute renal failure and thrombocytopenia, was admitted to our hospital. Further examinations revealed findings compatible with active lupus nephritis. Moreover, she was found to be positive for antiphospholipid antibody, and anticardiolipin antibody, as well as for lupus anticoagulant and syphilis test. Intensive treatment by methylprednisolone pulse therapy, hemodialysis, and double filtration plasmapheresis were performed. However, 13 days after admission she died suddenly because of intracranial hemorrhage. Pathological investigation of renal tissue revealed severe fibrinoid necrosis of the arterioles mainly in the glomerular afferent arteriole associated with diffuse proliferative lupus nephritis. In this case, hemolytic uremic syndrome (HUS) was associated with SLE. Antiphospholipid antibody was considered to be not only an accelerator in the arterial lesions of HUS, but also an initiator of HUS itself.

Renal vein thrombosis (RVT) can occur as a complication of the nephrotic syndrome. We present the case of a young woman with systemic lupus erythematosus with nephrotic syndrome and bilateral RVT with extension of the thrombus into the vena cava to the level of the right atrium and multiple pulmonary emboli. She was treated acutely with streptokinase, with complete resolution of the thrombi. In general, anticoagulation is the mainstay of therapy for RVT. Review of the literature reveals that thrombolytic therapy can be used safely and appears to have been reserved for those patients with the most severe disease or the more grave prognosis. we feel that thrombolytic therapy is warranted in the presence of bilateral RVT with acute renal failure, massive clot size with high risk of acute embolic events, or recurrent pulmonary emboli, in the absence of overriding contraindications.

We report a case of a child who was first seen for acute renal failure and periarteritis nodosa. Angiography findings confirmed this diagnosis. Ultrasound scan revealed large tricuspid valve vegetation, as well as minute vegetation on the right ventricular wall. All vegetation disappeared after 12 months of immunosuppressive therapy. Serology findings for lupus were negative. All clinical and laboratory findings strongly support the hypothesis that this previously undescribed heart involvement is caused by PAN.

A case of pure red cell aplasia (PRCA) with various complications polyarthritis, angitis, acute renal failure and DIC was successfully treated with steroid pulse therapy was described. A 55-year-old woman was hospitalized with a 9-month of intermittent but progressive joint pain, morning stiffness, general fatigue, and fever. Her initial laboratory evaluation revealed a hemoglobin of 4.4 g/dl and absence of reticulocyte. Her bone marrow aspirate showed no erythroblast which was compatible with a diagnosis of PRCA. Marked leukocytosis and thrombocytosis, positive antinuclear antigen, elevation of gammaglobulin and C-reactive protein and the presence of polyarthritis and angitis which was confirmed by renal angiography, indicated an underlying autoimmune disorders. Steroid pulse therapy was administered at 500 mg/day for 3 days, resulting in the complete response in both red cell aplasia and above findings. PRCA is known to be associated with systemic lupus erythematosus and rheumatoid arthritis very rarely, but this case did not fulfill the criteria of known collagen diseases, and there is no previous report representing PRCA with various complications such as polyarthritis, angitis and acute renal failure. This case may help us to understand more about the relationship between PRCA and autoimmune disorders.

The primary antiphospholipid/anticardiolipin syndrome is a recently described entity wherein multiorgan thrombotic events occur in the absence of objective evidence of systemic lupus erythematosus. The spectrum of renal involvement remains poorly described. Two patients with coagulation abnormalities consistent with the primary antiphospholipid/anticardiolipin syndrome who developed profound renal insufficiency are reported. Striking microangiopathic lesions were documented on renal biopsy. Renal function improved concomitant to the institution of steroid therapy. Reversible renal failure should be added to the spectrum of clinical manifestations of this entity. The diagnosis of the primary antiphospholipid/anticardiolipin syndrome should be contemplated in individuals with unexplained acute renal failure.

Hereditary complete C4 deficiency has until now been detected in 18 patients. A disturbed clearance of immune complexes probably predisposes these individuals to systemic lupus erythematosus and other immune complex diseases. Renal involvement of hereditary complete C4 deficiency is described in seven patients from three families. Three patients of one family suffered from SLE and a severe mesangial and endocapillary proliferative glomerulonephritis which required immunosuppressive treatment. In two patients from a second family a mild focal and segmental mesangioproliferative glomerulonephritis was present which, except for an episode of acute renal failure in one patient, did not cause serious clinical problems. One additional child died without renal involvement. The patient from a third family developed Henoch-Schoenlein purpura, mesangioproliferative glomerulonephritis with segmental scarring and terminal renal failure. Immunofluorescence studies showed deposition of immunoglobulins and complement C3 in the glomeruli. Severity of renal disease is probably determined by activation of the alternative pathway of complement in the kidney.

A 27-year-old Caucasian female, with a past history of recurrent spontaneous abortions, was admitted with pre-eclampsia at 26 weeks' gestation during her sixth pregnancy. She was previously known to have antiphospholipid antibodies since her fifth abortion, but had no clinical or serological evidence of systemic lupus erythematosus. A small-for-dates infant was delivered by emergency Caesarean section at 27 weeks for poor placental blood flow and fetal distress. She was transferred to the renal unit on the sixth post partum day with pulmonary edema, hypertension, disseminated intravascular coagulation and acute renal failure. Renal biopsy showed lesions compatible with thrombotic microangiopathy with diffuse glomerular necrosis. She was plasma exchanged and remained dialysis dependent for 7 months. Antiphospholipid antibodies were present in high titres and were the presumed cause of her acute renal failure. The patient now has stable renal function with a creatinine clearance of 30 ml/min for over two years. The late recovery of renal function is unique in the above circumstances.

A 45-year-old woman who had been diagnosed as having systemic lupus erythematosus (SLE) at the age of 28 years and who had been in remission developed severe urinary frequency, watery diarrhea, vomiting and weight loss. She also developed acute renal failure and her serological examination was consistent with active SLE. She had a markedly decreased urinary bladder capacity of 20 ml with hydroureteronephrosis. Histopathological study of her urinary bladder biopsy specimen showed mucosal edema, infiltration by lymphocytes and granulocytes, and deposition of IgA in the epithelium and submucosal region. We diagnosed this as a case of lupus cystitis. The patient's symptoms were alleviated by bilateral nephrostomy and corticosteroid therapy. In the present episode the patient showed none of the usual symptoms of SLE. This case and others reported in the literature show that lupus cystitis presents with specific signs and symptoms and therefore, this syndrome may represent a specific clinical manifestation of SLE.

Continuous hemofiltration (CH) is being used in increasing numbers of pediatric intensive care unit patients. Experience with 114 CH treatments in 98 critically ill children from March 1988 to March 1993 is presented in this study. Ages ranged from 1 day to 23 yr (mean +/- SE = 7.1 +/- 0.7 yr), and 54% of patients were male. Seventeen percent of all treatments were performed in neonates under 1 month of age. The most common primary diagnoses were sepsis and adult respiratory distress syndrome (11 patients each), liver transplantation and hypoplastic left heart syndrome (10 patients each), and hemolytic uremic syndrome (9 patients). The most frequent indications for CH were fluid overload and acute renal failure (42% each). Choices for CH included: continuous arteriovenous hemofiltration (CAVH, 50%), continuous arteriovenous hemodiafiltration (CAVH, 23%), continuous venovenous hemofiltration (CVVH, 18%), and continuous venovenous hemodiafiltration (CVVH-D, 9%). Choices for anticoagulation included: none (47%), regional (49%), and systemic (4%). Treatment duration ranged from 1 to 25 days (mean = 5.3 +/- 0.4 days). Mean filter life span for 363 filters was 0.94 +/- 0.1 filters/patient per day. Despite an overall survival rate of 43%, survival to discharge varied greatly (0 to 100%) among the 24 diagnostic groups: tumor lysis syndrome and systemic lupus erythematosus (3/3 patients each, 100%), hemolytic uremic syndrome (8/9 patients, 89%). This compares with: bone marrow transplantation (0/6 patients, 0%), hypoplastic left heart syndrome (2/10 patients, 20%), and leukemia (1/4 patients, 25%). Survival to hospital discharge was better in patients who did not receive pressors (P < 0.005) and in patients treated with combined ultrafiltration and dialysis (CAVH-D, CVVH-D) compared with ultrafiltration alone (CAVH, CVVH) (P < 0.005), but was not notably affected by patient age, sex, use of anticoagulation, filter life span, blood pump-assisted versus spontaneous CH, or duration of therapy. Filter life span was not affected by use of anticoagulation, but was remarkably longer in patients with arteriovenous versus venovenous CH (P < 0.004). It was concluded that: (1) empirical anticoagulation of patients treated with CH is not necessary; (2) children with a minority of underlying diseases and those requiring pressor support at initiation of CH appear to have relatively poor survival rates despite the technically effective use of CH; and (3) the addition of countercurrent dialysis to routine CH may enhance patient survival to hospital discharge.
