Haemolytic-uraemic syndrome (HUS) is a serious sequela of diarrhoea and results in a high mortality rate.
This systematic review aimed at estimating the proportion of HUS cases that are linked to prior infection
due to Shiga toxin-producing Escherichia coli
(STEC) or Shigella dysenteriae
type 1. A systematic review of the
existing literature was done to identify cohort and case-control studies that examined the relationship between
STEC and S. dysenteriae
type 1 and HUS. After screening 2,516 articles, 11 studies were found that met
the inclusion/exclusion criteria. Findings of case-control studies suggest that 60.8% of the HUS cases may
be attributable to a previous infection with STEC. In cohort studies, 7.8% of participants with STEC and 8%
of participants with S. dysenteriae
type 1 developed HUS during follow-up. HUS is linked to diarrhoea due to
both STEC and S. dysenteriae
type 1. Thus, preventing infections caused by both pathogens is critical for the
prevention and control of HUS, especially in areas where timely and effective treatment is not available.
