Haemolytic uraemic syndrome (HUS) associated with Escherichia coli O157:H7 is the commonest cause of acute renal failure (ARF) in childhood. Production of verotoxin by the organism is pivotal in the pathogenesis of the disease. Verotoxin binds to a receptor on blood and endothelial cells, expressed as the P1 blood group antigen on red blood cells. A protective effect of the P1 phenotype has been proposed in this disease. This study investigates prognostic factors and the relationship between outcome and P1 phenotype in 27 cases of diarrhoea-associated HUS. A poor outcome as defined by the presence of chronic renal failure (CRF), hypertension or proteinuria on 6 month follow-up was associated with the age of the patient at presentation and with the following clinical markers: maximum WBC and duration of raised WBC, duration of anuria and duration of need for dialysis. None of these outcome measures or prognostic factors, and no extra-renal manifestations of the disease were associated with P1 phenotype.

A 10-year-old boy with epidermolysis bullosa simplex (Weber-Cockayne variant) together with leukocytoclastic vasculitis is presented. He was admitted to the hospital with the provisional diagnoses of infected epidermolysis bullosa simplex or drug eruption. On the sixth day of hospitalization he developed palpable purpura, abdominal pain and bloody diarrhea, together with hematuria and proteinuria. A generalized tonic-clonic convulsion, changes in mental status, fluctuations in arterial blood pressure and intractable pain in his extremities occurred during the course of hospitalization. Systemic pulse steroid therapy, antibiotics, and antihypertensive and anticonvulsive drugs were given. On the 30th day of hospitalization, a skin graft was performed to replace a large tissue defect on his left hand. Despite high dose steroid therapy, his hematuria, proteinuria and hypertension continued after his discharge, suggesting a steroid-resistant renal pathology, such as focal glomerulosclerosis, that occurred secondary to leukocytoclastic vasculitis.

We reported 2 children with suspected primary vasculitis of mesenteric vessels. Both children were admitted to our hospital with the complaints of abdominal pain, bloody stool or diarrhea. Laboratory examination simultaneously revealed leukocytosis with dominant neutrophils, positive CRP, and hypoalbuminemia. Although prothrombin time and activated partial thromboplastin time were within normal limits, the increased levels of FDP-E, D-dimer, and von Willebrand factor activity were observed, which suggested the endothelial cell activation and the coagulation/fibrinolysis system activation. Abdominal echography and CT scanning demonstrated the edematous thickening of intestinal or colon walls probably due to the vasculitic permeability changes of mesenteric artery. During the disease courses, skin rash, bleeding tendency, arthritis and proteinuria were not observed, and no autoantibodies including anti-nuclear antibody, anti-DNA antibody, and myeloperoxidase-antineutrophil cytoplasmic antibody, were detected. Taken together, we suspected these children as restricted vasculitis of mesenteric vessels. Intravenous prednisolone was administrated, and the clinical and laboratory abnormalities recovered completely within 2 weeks. Thus, we suggested that the leukocyte counts, CRP, and the determination of von Willebrand factor and coagulation/fibrinolysis study accompanied with X-ray, echography, and CT scanning will be useful for the early diagnosis of vasculitis before the pathologic and irreversible vascular damage are demonstrated.

A fifteen-year-old boy was admitted to our hospital because of lower abdominal pain, watery diarrhea and mucobloody stool. Two years before admission, he was diagnosed to have Still's disease presenting with polyarthritis, sore throat, remittent fever and typical skin rash. He had been treated with non-steroidal anti-inflammatory agents, oral prednisolone and low-dose methotrexate. Although he was almost free of symptoms during the next two years, serum C-reactive protein (CRP) levels continued to be elevated moderately. He began to complain of lower abdominal pain and loose stool in May 1997 and came down with mucous-bloody diarrhea in June. Laboratory data on admission showed an elevated level of serum CRP (13.9 mg/dl). The biopsy of the stomach, ileum, sigmoid colon and rectum revealed the deposition of amyloid protein of AA type, which confirmed the diagnosis of secondary amyloidosis. The dose of prednisolone was increased and dimethyl sulfoxide per os or rectum was instituted, which improved his gastro-intestinal symptoms to some extent. However, fever, arthritis and diarrhea recurred along with tapered prednisolone dosage. In addition to gastro-intestinal symptoms, arrhythmia and proteinuria appeared. These symptoms were considered to reflect general deposition of amyloid in his body. He is now on immunosuppressive agent and high-dose prednisolone. Several studies report the higher frequency of gamma-allele of SAA 1 gene in the cases of rheumatoid arthritis with AA-amyloidosis than in those without. In the patient presented here, molecular biological analysis revealed that his SAA 1 gene was composed of beta- and gamma-allele. The presence of gamma-allele in his SAA 1 gene might be one of the factors that predisposed him for generalized deposition of amyloid protein in such a short period of time.

Secondary amyloidosis is an occasional complication of ankylosing spondylitis (AS) and in most cases renal amyloidosis presents with proteinuria, nephrotic syndrome and decreased renal function. We describe a 32-year-old male patient with AS manifested by frequent diarrhea, intermittent abdominal pain and low serum albumin levels. He has suffered from severe inflammatory back pain for 14 years with multiple peripheral joint involvement. Protein-losing enteropathy due to gastrointestinal amyloidosis was diagnosed with 99mTc-human albumin scintigraphy, fecal alpha-1 antitrypsin clearance and colonoscopic biopsy with Congo red staining. Somatostatin analogue octreotide and prednisolone were introduced with successful result.

In the case of a 21-year-old patient gastroscopy and coloscopy were performed because of recurrent abdominal pain with diarrhea and vomiting. Colonoscopy showed moderate signs of inflammation of the rectum and aphthoid ulcerations in the terminal ileum. Since the macroscopic and clinical presentation was compatible with Crohn's disease, therapy with sulfasalacine was started. Because histology showed only lymphoid hyperplasia and the patient was asymptomatic at that time, the medication was ceased. Recurrence of abdominal pain and weight loss, proteinuria and a recurrent palpable purpura of the shanks in synopsis with the result of the previous colonoscopy led to a suspected diagnosis of Schoenlein-Henoch purpura with cutaneous, renal and abdominal manifestation which was confirmed by dermal and renal biopsies.

We report on two children, a 12-year-old boy and a 6-year-old girl, with simultaneous occurrence of clinical and laboratory features consistent with both diarrhoea-negative haemolytic uraemic syndrome (D-HUS) and acute post-infectious glomerulonephritis (APGN). Both presented with acute renal insufficiency, hypertension and oedema. Laboratory evaluation revealed micro-angiopathic anaemia with burr cells, thrombocytopenia, elevated lactic dehydrogenase and low complement C3. Urinalysis showed marked proteinuria and haematuria. Renal biopsy was characteristic of APGN, but not of HUS. The outcome was good in both children. Conclusion. The simultaneous occurrence of diarrhoea-negative haemolytic uraemic syndrome and acute post-infectious glomerulonephritis is rare. The outcome is generally good as is expected in the latter condition in contrast to the former.

We report a case of Churg-Strauss syndrome with renal involvement. A 51-year-old woman was admitted to our hospital in April of 1999 complaining of abdominal pain and severe diarrhea followed by multiple purpura on both legs. A diagnosis of Churg-Strauss syndrome was made on the basis of the presence of preceding asthma, eosinophilia, increased IgE, and the histological findings of a biopsy taken from the purpura. Creatinine clearance level at admission was low (43.3 ml/min) and urinalysis revealed proteinuria and microscopic hematuria. These abnormalities were improved with systemic steroid therapy. Renal involvement seems to be more common than previously reported in Churg-Strauss syndrome.

We correlated age and body surface area corrected glomerular filtration rate (GFR) at the time of high-dose melphalan (HDM) administration with treatment-related toxicity (TT), time to disease progression and survival. Between 8/85 and 6/98, 144 newly diagnosed myeloma patients with a median age of 53 years (range, 31-72) received infusional chemotherapy with vincristine, doxorubicin and methylprednisolone, with/without cyclophosphamide or verapamil, followed by HDM 200 mg/m(2)and stem cell rescue. An additional patient received HDM at diagnosis. GFR was below normal in 38 patients (26%). At presentation, patients with low GFR at the time of HDM had higher serum creatinine, beta(2)M, stage III disease, calcium and Bence-Jones proteinuria. Toxic deaths post-HDM were similar in both groups (2/38 (5%) vs. 4/107 (4%)), though patients with low GFR had more oral mucositis (P< 0.0001), diarrhoea (P = 0.005) and infections (P = 0.04). The response and relapse rates of the 2 groups were not substantially different, but the median overall survival (OS) was significantly shorter in patients with low GFR (5.1 vs 7.5 years, P = 0.015). Multivariate analysis showed that a normal GFR and being in CR at the time of HDM were predictive of longer OS. We conclude that in context of high-dose chemotherapy for myeloma, dose of melphalan should not be modified in patients with low GFR and that early intensive treatment at relapse may improve results in patients with abnormal renal function.

Every year in France, about 100 children, most of them less than 3 years old, have typical diarrhea-associated HUS (D + HUS). Evidence of exposure to verotoxin producing E. coli (VTEC), mostly the O157: H7 serotype, is demonstrated in about 85% of cases. A prodromal illness of acute gastroenteritis with diarrhea, often bloody, precedes the HUS by 1 to 15 days. HUS onset is sudden, with the typical association of hemolytic anemia with fragmented red blood cells, thrombocytopenia and acute renal insufficiency. Involvement of other organs than the kidneys may occur, such as severe hemorrhagic colitis with rectal prolapse, bowel wall necrosis or secondary stenosis, acute pancreatitis, central nervous system involvement which determines the vital outcome. Early accurate supportive treatment allows a current mortality rate below 5%, with most deaths due to central nervous system involvement. Five to 10% of children develop end stage renal disease, rarely directly, more often after having recovered some renal function with chronic renal insufficiency during a few years. After 15 or more years follow-up, at least one third of patients have some degree of proteinuria and/or hypertension, and eventually chronic or end stage renal failure. Predictive features of poor renal outcome at the acute phase are severe gastrointestinal involvement, severe CNS involvement, polyncleosis over 20,000/mm3, and duration of initial anuria longer than one week. The role of VTEC in D + HUS makes the disease a public health problem. Preventive measures are essential.
