Characterizing Long-Term Health Outcomes and Health Related Quality of Life Among Families Affected by Hemolytic Uremic Syndrome (HUS)
Foodborne pathogens can lead to acute and chronic illness but little is known about the psychosocial costs to the individuals sickened and their families. To fill this knowledge gap, we surveyed families of individuals who developed HUS, a serious complication that can develop during acute foodborne disease. Results will improve burden of disease estimates as well as clinical management of HUS patients.
Our research on long-term health outcomes focuses on individuals affected by HUS among whom outcomes range from blood disorders, hypertension, and chronic or end-stage kidney disease to non-renal outcomes such as diabetes or cognitive sequelae. There is also a growing body of evidence for long-term health outcomes such as clinical post-traumatic stress disorder among the families of those affected by HUS.
CFI completed a survey of families and individuals affected by HUS collecting information on acute and chronic illness history as well as epidemiological, sociodemographic, and genetic factors. Responses were collected for 74 cases comprising 71 families. Approximately 60% of the cases developed HUS when they were < 5 years old with some respondents reporting outcomes 30+ years following HUS onset. Preliminary descriptive analyses were presented in July at the 2019 Annual Meeting of the International Association for Food Protection.

The Impact of Foodborne Illness on Long-Term Health Outcomes
In addition to acute gastrointestinal symptoms characteristic of foodborne illness, it is increasingly recognized that foodborne illnesses can also contribute to other secondary long-term health complications.
There is little epidemiologic data on the long-term health outcomes associated with acute foodborne disease and many of these associations have come from case series and small-scale studies that have inconsistent follow-up and additional research is needed to understand the long-term burden of foodborne illness (Roberts 2009). For example, having a Salmonella infection is one of the leading predictors for developing reactive arthritis, a painful, chronic and potentially debilitating condition that causes joint inflammation.Campylobacter is a leading cause of Guillain-Barre Syndrome, an autoimmune disease that causes paralysis and kills five to ten percent of its victims. Listeria monocytogenes kills more than 1/3 of its perinatal victims and 20% of all its victims, making it one of the most lethal foodborne pathogens. E. coli O157:H7 and other Shiga toxin-producing foodborne pathogens are the primary cause of hemolytic uremic syndrome (HUS), the leading cause of acute kidney failure in children under five years of age in the United States.
