One patient of sepsis by P. aeruginosa after the implanting of a ventriculoatrial valve following extirpation of an expansive intracranial process is studied. During the evolution of the septic process there appeared as associated nephrotic syndrome with histologic lesions corresponding to an acute exudative glomerular nephritis. The germ became resistant to the antibiotics used, carbenicillin plus gentamicin, being later sensitive only to fosfomycin with which finally complete cure was achieved.

In patients with cerebrospinal fluid internal shunts, immune complex glomerulonephritis sometimes develops. Of two new cases the first was classic, while the second was in an adult who had had a ventriculoatril shunt for 8 years; furthermore, the patient had acute renal failure and is the first to have been reported to have Peptococcus septicemia. Shunt glomerulonephritis is characterized by the following: (a) its occurrence following, most often, Staphylococcus albus infection in a patient who usually has a ventriculoatrial shunt; (b) transitory improvement of the symptoms by antibiotherapy only; and (c) full recovery if the prosthesis is removed. Laboratory studies show a low serum concentration of the C3 component of complement, the presence of cryoglobulins and a positive rheumatoid factor test. These abnormalities are reversible with removal of the prosthesis. Optical microscopy of a renal biopsy specimen in the two cases showed cellular proliferation of the glomerular tuft, electron microscopy demonstrated subepithelial deposits and immunofluorescent studies revealed intramembranous and intramesangial immune complexes. These features are similar to those observed in experimental nephritis induced in animals by foreign protein.

Seventy-one patients with systemic lupus erythematosus and clinical evidence of nephritis were seen during a 15-year period, and followed for a mean of seven years. Survival was calculated to be 76 per cent at five years and 57 per cent at ten years from onset of clinical nephritis; and 80, 65, 55 and 55 per cent five, ten, fifteen and twenty years from onset of clinical lupus. Renal biopsies showed mild or focal lesions in 30 per cent of patients, membranous lesions in 14 per cent and diffuse proliferative lesions in 55 per cent. However, there was no difference in the long-term outcome of the different histological groups. Nineteen patients (27 per cent) died during follow up, eleven from renal failure, six from sepsis and two from cerebral lupus. Death in renal failure is now usually a late event in lupus, even in patients with clinical evidence of severe nephritis. The prognosis of even severe lupus nephritis is now better than formerly reported. Reducing the dose of corticosteroid drugs, by the use of cytotoxic drugs such as azathioprine may have diminished the mortality from cardiovascular complications. Side effects of treatment, however, remain an important cause of death and morbidity.

A 22-year-old white male (L.V.) died of gram-negative septicemia complicating infectious mononucleosis (IM) that was associated with jaundice and oliguric renal failure. The kidney showed mesangial granular deposits of IgM and C3, mesangial electrondense deposits, and interstitial infiltrates of infiltrates of mononuclear cells, including atypical lymphocytes. Eluates obtained from kidney, spleen and liver contained Paul--Bunnell (PB) antibodies. Presence of PB antigens in these tissues was indicated by absorption of PB antibodies from IM sera, with the sediments resulting from tissue elutions. The IgM mesangial deposits were partially eluted with acid buffer at 56 degrees C and then reconstituted by incubation with IM sera or with immunoglobulins eluted from tissues of patient L.V. The presence in renal structures of PB antigens, IgM heterophile antibody, C3 and electron-dense deposits is consistent with the hypothesis that heterophile immune complexes were localized in the kidney and that they contribute in the pathogenisis of IM nephritis.

Most adults with acute bacterial renal infection demonstrate no roentgen abnormality in the acute stage and recuperate without significant functional or morphological renal abnormality. We report the initial and long-term findings in a virulent form of acute bacterial nephritis caused by gram-negative organisms and predominantly in patients with diabetes and associated septicemia. The findings of a small, poorly functioning symmetrically scarred kidney with significant caliceal distortion and the associated angiographic abnormalities are presented for the first time in the long-term followup of this disease.

The changing pattern of mortality in systemic lupus erythematosus (SLE) led to an examination of the deaths in a long-term systematic analysis of 81 patients followed for five years at the University of Toronto Rheumatic Disease Unit. During the follow-up 11 patients died; six patients died within the first year after diagnosis (group I) and five patients died an average of 8.6 years (from 2.5 to 19.5 years) after diagnosis (group II). In those who died early, the SLE was active clinically and serologically, and nephritis was present in four. Their mean prednisone dose was 53.3 mg/day. In four patients a major septic episode contributed to their death. In those who died late in the course of the disease, only one patient had active lupus and none had active lupus nephritis. Their mean prednisone dose was 10.1 mg/day taken for a mean of 7.2 years. In none was sepsis a contributing factor to their death. All five of these patients had had a recent myocardial infarction at the time of death; in four, ti was the primary cause of death. Mortality in SLE follows a bimodal pattern. Patients who die early in the course of their disease, die with active lupus, receive large doses of steroids and have a remarkable incidence of infection. In those who die late in the course of the disease, death is associated with inactive lupus, long duration of steroid therapy and a striking incidence of myocardial infarction due to atherosclerotic heart disease.

With the purpose of establishing the clinicopathologic correlation in pyelonephritis and to discard other interstitial nephrites, with present day morphologic criteria we analysed 63 casos that had been diagnosed as pyelonephritis, following Weiss and Parker's histologic criterion. The clinicopathologic diagnosis of pyelonephritis was confirmed in 12 cases; all of them showed obstructive uropathy and in most of them, there was chronic renal failure. Interstitial nephritis was established in 27 cases, all of them showing septicemia and almost half of the cases showed acute renal failure. Other 20 cases showed tubulointerstitial nephritis secondary to different types of glomerulopathies, fetal glomerulosclerosis, dysplasias, nephrophthisis, radiation nephritis and renal infarct. In 4 cases, the study of sections finer than the original, showed absence of histopathologic lesions. The results of the present study point out the main causes of confusion with the pathological diagnosis of pyelonephritis, the necessity to investigate predisposing uropathy in patients with urinary infection and stresses the importance to establish correlation with clinical and laboratory findings in cases with tubulointerstitial lesions.

We retrospectively evaluated the clinical outcome of 45 female and 11 male patients with biopsy-proven lupus nephritis, followed at our hospital between February 1974 and February 1990. In the majority signs of nephritis were present at the time systemic lupus erythematosus was diagnosed (range: -42-156 months) and the median time from onset of nephritis to biopsy was 2 months. The median follow-up from the time of the biopsy was 53.5 months (range: 2-192), the median age at biopsy 25 years and the median serum creatinine level 1.2 mg/dl. Initial renal biopsies had the following histopathological classes according to the World Health Organization criteria (n): I (2); II (10); III (10); IV (28); V (5); VI (1). Over the study period active episodes were treated with high-dose oral prednisone alone or combined with intravenous nitrogen mustard and oral chlorambucil (1974-75), azathioprine (1978-86), cyclophosphamide (1986-90) and/or plasma-exchange (1976-84). These strategies were based on literature data or multicenter studies in which we participated. Eight patients developed end-stage renal disease (ESRD) (median: 47 months post-biopsy; range: 20-120). In these, initial biopsies showed class IV in seven, and class V in one. Confounded risk factors for ESRD were class IV biopsy, male gender and serum creatinine level above 1.4 mg/dl. The calculated proportion without ESRD 5 years post-biopsy was 87% (95% confidence limits: 98-76%), and at 10 years 70% (95% confidence limits: 90-49%). Five patients (11.2%) died; causes of death were cerebrovascular accident (n = 2), cerebral lupus (n = 2) and S. aureus sepsis (n = 1).(ABSTRACT TRUNCATED AT 250 WORDS)

Interleukin-1 (IL-1) is a 17-kDa pro-inflammatory cytokine synthesized from a variety of cell types primarily in association with disease states or during host perturbation such as immune responses. At pM or even fM concentrations, IL-1 triggers various responses in nearly all cells. It appears that there is little or no major role for IL-1 in homoeostatic mechanisms. There are two IL-1's (alpha and beta) each with its distinct sequence; there are two IL-1 receptors. Disease states such as local and systemic infection, septic shock, degenerative arthritis and autoimmune diseases such as nephritis, vasculitis and inflammatory bowel disease appear to be mediated, in part, by IL-1. Organ failure, capillary leak and death occur in animals after a combination of tumour necrosis factor (TNF) and IL-1 which is more effective in inducing these changes than either cytokine alone. IL-1 is also a potent inducer of endothelial cell adhesion molecules, IL-6, and IL-8, a neutrophil chemotactic and activating factor. Strategies for reducing the effects of IL-1 have been based on suppression of transcription, translation, or secretion; more recently, receptor blockade has been a new approach. A naturally occurring IL-1-specific receptor antagonist (IL-1ra), which shares 40% conserved amino-acid homology with IL-1 beta, binds to IL-1 surface receptors with the same affinity as IL-1 but does not possess agonist activity and acts as a competitive inhibitor of IL-1. Studies using the IL-1ra to block endogenous IL-1 in a variety of animal disease models suggest that IL-1 plays a key role in triggering the cascade of inflammatory responses. In addition, the IL-1ra reduces the spontaneous production of growth factors and proliferation of leukaemic cells. The IL-1ra may be an advantageous therapy in patients with sepsis, diabetes, inflammatory bowel, arthritis and cancer.

Six years of necropsy records from a zoo colony of four tamarin species (Saguinus oedipus, S. geoffroyi, S. imperator, and S. mystax) were examined. Mean age at death was 4.0 years, average length in the colony at time of death was 3.4 years. Annual mortality rate varied between 9 and 30%. Gross necropsy findings, histopathologic, and bacteriological results indicate primary cause of death as follows: peritonitis (26%), septicemia (14%), nephritis (5%), hepatitis (5%), pneumonia (2%), and others.
