A case of right-sided Pseudomonas cepacia endocarditis in a heroin addict is presented in which septic cutaneous vasculitis (ecthyma gangrenosum) is a prominent feature. Ecthyma gangrenosum, most commonly associated with sepsis due to P aeruginosa, has not been previously described with P cepacia septicemia.

A patient is described who was treated with high-dose prednisone in an attempt to halt progressive respiratory insufficiency associated with diffuse interstitial fibrosis. On cessation of steroid therapy the patient was noted to have radiologic manifestations of hypertrophic osteoarthropathy (HOA) as well as clinical and laboratory features of rheumatoid arthritis (RA). Subsequently a diffuse vasculitis developed with bowel perforation and sepsis leading to death.

Gastrointestinal manifestations in a lupus patient may be due to different aetiologies such as vasculitis or a surgical condition. Problems of diagnosis are frequently encountered because the clinical presentations may mimic each other. We analysed ten lupus patients with acute surgical abdomen to identify the clinical, laboratory and radiological features that may aid in early diagnosis and management. Three patients with surgical abdomen had concomitant active lupus. Intra-abdominal sepsis and bleeding peptic ulcer disease constituted two major causes of laparotomies. Overt signs of peritonitis might not be present due to steroid masking effect. There were no specific clinical features, laboratory or radiological tests that could distinguish gastrointestinal vasculitis from acute surgical abdomen. Blood cultures, C-reactive protein and CT abdomen were useful adjuncts in the management of abdominal sepsis. No correlation was found between the timing of surgery, mortality, steroid dosage and wound complication.

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.

A 43-yr-old woman developed carcinoma of the ampulla of Vater 20 yr after being successfully treated for Hodgkin's disease with radiotherapy and chemotherapy. Conditions related to the chronic effect of radiation, such as narrowing and fibrosis of abdominal tissue, hampered her diagnosis and treatment. After a total pancreatectomy to remove the carcinoma, the patient recovered. However, 15 months later, she developed severe digestive disturbances, adrenal insufficiency, pulmonary emboli, and vasculitis. She died the next month of sepsis and adult respiratory distress syndrome. Although her complications probably were related to residual effects from therapy and surgery, she had no clinical evidence of tumor recurrence.

We report a patient with an upper respiratory tract infection who presented outbreaks of erythematosus-purpuric macules and papules (the pathological substrate of which was a leukocytoclastic vasculitis with numerous intravascular thrombi) coinciding with two autolimited febrile episodes. In serial hemocultures B meningococcus was identified oral antibiotic treatment was given achieving a good clinical evolution. Although both episodes could be considered as a meningococcemia without sepsis, they could also correspond to the initial phase of a chronic meningococcemia. The possible etiopathogenesis of the cutaneous lesions is discussed and the therapeutic and prognostic repercussion of an early identification of these forms of meningococcal disease, which are poorly expressed clinically, are highlighted.

We report a case of idiopathic crescentic glomerulonephritis with pulmonary hemorrhage associated with anti-myeloperoxidase antibodies (anti-MPO ab). A 74 year-old female was admitted to our hospital because of rapidly progressive glomerulonephritic syndrome and dyspnea with bloody sputum. On admission anti-MPO ab, one of anti-neutrophil cytoplasmic antibodies, were detected but anti-GBM antibodies and immune complexes were not detected. Renal biopsy showed crescentic glomerulonephritis and lung biopsy showed massive alveolar hemorrhage. Both tissue had pauci-immune deposit by immunofluorescence microscopy. Hemodialysis and steroid administration were started. Pulmonary hemorrhage was improved remarkably, but renal failure progressed rapidly to end stage kidney, then hemodialysis was continued. Although subsequent 3 years uneventful maintenance hemodialysis had been performed, she admitted to our hospital again because of progressive dyspnea with hemoptysis after upper respiratory tract infection. On admission anti-MPO ab were detected again and steroid administration was started. Pulmonary hemorrhage was improved with decreased anti-MPO ab titer. While tapering the dosis of steroid, anti-MPO ab again increased and pulmonary hemorrhage recurred. Although pulse methylprednisolone therapy and plasma exchange were performed, respiratory failure progressed rapidly and she died of sepsis. Postmortem examination showed no evidence of systemic vasculitis. In this case, titer of anti-MPO ab was associated with not only idiopathic crescentic glomerulonephritis but also with pulmonary hemorrhage. We tried to detect enzymatically active MPO in serum. Titer of serum MPO was also associated with disease activity and anti-MPO ab. It is suggested that both anti-MPO ab and serum MPO are closely related to the pathogenesis of idiopathic crescentic glomerulonephritis and pulmonary hemorrhage.

A fourteen month old infant was admitted for evaluation because of continuous high fever and an indurated nodular lesion at the left thigh of one month course. After admittance painful inflammatory subcutaneous nodules appeared in the face and trunk, these were accompanied by enlarged cervical lymph nodes and hepatomegaly. Histological evaluation of the skin biopsy showed destruction of subcutaneous tissue, foamy cells, vasculitis and polymorphonuclear leukocyte infiltration; histiocytic proliferation in the lymph nodes and steatosis in the liver biopsy. Osteoarticular infection, cellulitis, sepsis, tuberculosis, collagen disease, and malignancies of hematologic origin were all ruled out. Response to treatment with prednisone was excellent and the patient has been asymptomatic along a one year follow up period.

Fourteen patients with Wegener's granulomatosis (WG) and severe renal and extrarenal involvement were studied (serum creatinine on admission 5.8 +/- 3.4 mg/dl). Renal histology showed a necrotizing, crescentic glomerulonephritis in all patients. Despite advanced renal disease on admission cyclophosphamide, steroids (in 13 patients) and plasma exchange (in 9 patients) caused a rapid and sustained improvement of renal function. Four patients required intermittent hemodialysis over a period of one week. After 2 weeks of treatment serum creatinine values below 2 mg/dl (n = 4) indicated a nearly complete recovery of renal function in the long-term follow up (mean serum creatinine achieved after 12 months therapy: 1.1 +/- 0.1 mg/dl (n = 4). Therefore serum creatinine values observed after 2 weeks of therapy, appear to be of prognostic value with regard to renal outcome. No relapse of active WG or progressive renal deterioration was observed during follow-up (22 +/- 13 months) except in one patient with persisting renal impairment. Three patients died (staphylococcus sepsis, intracerebral hemorrhage during hypertensive crisis, pulmonary embolism) during the first two months of therapy. The decline of serum creatinine seemed to be a better indicator of successful therapy than the decrease of anticytoplasmatic antibody (ANCA), erythrocyte sedimentation rate (ESR) and hematuria. On admission ANCA titer neither correlated with serum creatinine, the degree of renal involvement, nor was it of prognostic value. ANCA, serum creatinine and hematuria normalized within 2 to 8 months, whereas ESR and proteinuria remained elevated. Our data indicate a good prognosis of WG even with advanced renal involvement and generalized vasculitis provided aggressive treatment is performed early.

Skeletal muscle wasting is commonly observed in critically-ill patients and has been attributed to catabolic fibre atrophy and to neuropathy. This study describes the occurrence of a necrotizing myopathy in 15 out of 31 critically-ill patients who had percutaneous biopsies taken from the tibialis anterior muscles. While most cases showed necrosis of isolated fibres, 5 of the 12 patients who had serial biopsies showed progressive necrosis of up to 95 per cent of the fibres. One other case showed infarction and one case had staphylococcal vasculitis. Atrophy of type 1 and/or type 2 fibres was documented by morphometry in 12 cases. Myoglobin-containing casts were demonstrated immunohistochemically in renal tubules on either biopsy or necropsy material in 5 out of 7 cases. The presence of muscle necrosis was a clinically unexpected finding which may contribute to weakness, complicate the interpretation of tissue biochemistry and energy balance studies, and potentiate renal failure. The necrosis is probably multifactorial in origin, with ischaemia and sepsis contributing factors.
