چکیده
OBJECTIVE To evaluate the effect of different treatment strategies on enterohaemorrhagic Escherichia coli O104:H4 induced haemolytic uraemic syndrome. DESIGN Multicentre retrospective case-control study. SETTING 23 hospitals in northern Germany. PARTICIPANTS 298 adults with enterohaemorrhagic E coli induced haemolytic uraemic syndrome. MAIN OUTCOME MEASURES Dialysis, seizures, mechanical ventilation, abdominal surgery owing to perforation of the bowel or bowel necrosis, and death. RESULTS 160 of the 298 patients (54%) temporarily required dialysis, with only three needing treatment long term. 37 patients (12%) had seizures, 54 (18%) required mechanical ventilation, and 12 (4%) died. No clear benefit was found from use of plasmapheresis or plasmapheresis with glucocorticoids. 67 of the patients were treated with eculizumab, a monoclonal antibody directed against the complement cascade. No short term benefit was detected that could be attributed to this treatment. 52 patients in one centre that used a strategy of aggressive treatment with combined antibiotics had fewer seizures (2% v 15%, P = 0.03), fewer deaths (0% v 5%, p = 0.029), required no abdominal surgery, and excreted E coli for a shorter duration. CONCLUSIONS Enterohaemorrhagic E coli induced haemolytic uraemic syndrome is a severe self limiting acute condition. Our findings question the benefit of eculizumab and of plasmapheresis with or without glucocorticoids. Patients with established haemolytic uraemic syndrome seemed to benefit from antibiotic treatment and this should be investigated in a controlled trial.

Psychiatric Symptoms in Patients with Shiga Toxin-Producing E. coli O104:H4 Induced Haemolytic-Uraemic Syndrome
BACKGROUND In May 2011 an outbreak of Shiga toxin-producing enterohaemorrhagic E. coli (STEC) O104:H4 in Northern Germany led to a high number of in-patients, suffering from post-enteritis haemolytic-uraemic syndrome (HUS) and often severe affection of the central nervous system. To our knowledge so far only neurological manifestations have been described systematically in literature. AIM To ...
متن کاملEscherichia coli (STEC) serotype O104 outbreak causing haemolytic syndrome (HUS) in Germany and France.
At the beginning of May an outbreak of bloody diarrhoea and haemolytic uraemic syndrome (HUS) began in Germany. During the succeeding months following the initial outbreak in Germany, thousands of infections occurred resulting in 877 cases of haemolytic uraemic syndrome (HUS) with 32 deaths and 3,043 cases of enterohaemorrhagic Escherichia coli (EHEC) with 16 deaths.

It is over. The outbreak of the enterohaemorrhagic Escherichia coli (EHEC) O104:H4 infection that had its major focus in Germany [1] and affected people in many other European countries has officially come to an end [2]. While the media coverage has been decreasing, the scientific community has been working to understand the reason why this dramatic outbreak occurred. We have learnt that the pa...
متن کاملVirulence from vesicles: Novel mechanisms of host cell injury by Escherichia coli O104:H4 outbreak strain
The highly virulent Escherichia coli O104:H4 that caused the large 2011 outbreak of diarrhoea and haemolytic uraemic syndrome secretes blended virulence factors of enterohaemorrhagic and enteroaggregative E. coli, but their secretion pathways are unknown. We demonstrate that the outbreak strain releases a cocktail of virulence factors via outer membrane vesicles (OMVs) shed during growth. The O...
متن کاملColonic ischaemia as a severe Shiga toxin/verotoxin producing Escherichia coli O104:H4 complication in a patient without haemolytic uraemic syndrome, Germany, June 2011.
An increasing rate of infections with Shiga toxin/verotoxin-producing Escherichia coli (STEC/VTEC) O104:H4 has been observed in Germany since May 2011, with unusually high numbers of patients suffering from haemolytic uraemic syndrome (HUS). We report a STEC/VTEC O104:H4 case without HUS, presenting with colonic ischaemia demanding surgery. This atypical clinical presentation of STEC O104:H4 in...
