Eleven rhesus monkeys were monitored intensively during experimental infection with Ebola virus. Prominent neutrophilia with left shift and lymphopenia were the earliest abnormalities and were statistically significant by day 4 (P less than .02 and P less than .01, respectively). By day 4 falls in platelet counts were not statistically significant, whereas(More)
BACKGROUND After a drought in February, 1996, all 126 patients in a haemodialysis unit in Caruaru, north-east Brazil, developed signs and symptoms of acute neurotoxicity and subacute hepatotoxicity following the use of water from a lake with massive growth of cyanobacteria (blue-green algae). 60 patients died. METHODS Besides recording clinical details(More)
BACKGROUND The commonest cause of end-stage renal failure (ESRF) in children and young adults is congenital malformation of the kidney and urinary tract. In this retrospective review, we examine whether progression to ESRF can be predicted and whether treatment with angiotensin converting enzyme inhibitors (ACEI) can delay or prevent this. METHODS We(More)
The organs of monkeys infected with Ebola haemorrhagic fever were examined by light and electron microscopy during the acute stage of the disease. The virus caused focal coagulative necrosis in the liver, spleen, kidney, lung and testis and widespread mild vascular damage. In the brain there was intense congestion, with erythrocyte 'sludging', but no(More)
Patients with severe viral infections such as Lassa or Ebola may be denied adequate laboratory investigations because of justifiable fears among laboratory staff. This study in monkeys was designed to provide comprehensive haematological and biochemical monitoring in a contained environment during all stages of Ebola infection. Marked neutrophilia,(More)
D dimer and other large fragments produced during the breakdown of crosslinked fibrin may be measured by enzyme immunoassay using monoclonal antibodies. In 91 patients with renal disease and varying degrees of renal dysfunction, plasma D dimer showed no correlation with renal function, whereas FgE antigen, a fibrinogen derivative which is known to be(More)
This study investigates evidence of oxidative stress during bicarbonate hemodialysis by measuring total glutathione and lipid peroxidation products in plasma, and characterizes the free radicals produced by neutrophils from healthy volunteers when incubated in vitro with increasing concentrations of bicarbonate. Blood samples were taken from nine(More)
BACKGROUND Renal involvement is frequently present in antineutrophil cytoplasmic autoantibody (ANCA)-associated systemic vasculitis and is an important cause of end-stage renal failure (ESRF). METHODS This retrospective, multicenter, sequential cohort study reports presenting features and outcome of 246 new patients diagnosed in London, UK, between 1995(More)
BACKGROUND We highlight a chronic inflammatory disease we call 'hyper-IgG4 disease', which has many synonyms depending on the organ involved, the country of origin and the year of the report. It is characterized histologically by a lymphoplasmacytic inflammation with IgG4-positive cells and exuberant fibrosis, which leaves dense fibrosis on resolution. A(More)
