title: Reactive arthritis and Reiter's syndrome following an outbreak of gastroenteritis caused by Salmonella enteritidis.
abstract: Reactive arthritis and Reiter's syndrome have been reported following gastroenteritis. Prevalence studies for these conditions are uncommon, and the prevalence of Reiter's syndrome after Salmonella enteritidis infection has not been previously reported. After a large outbreak of S. enteritidis gastroenteritis, a survey of persons exposed to the implicated food source was conducted, and those with reactive arthritis were evaluated for possible risk factors. Among 481 persons responding to the questionnaire, 217 cases of S. enteritidis gastroenteritis were identified (31 confirmed and 186 clinical cases; attack rate, 45%). Twenty-nine percent of the cases had symptoms of reactive arthritis, 3% had symptoms of Reiter's syndrome, and 10% had reactive arthritis with oral ulcers. Markers for severe illness (diarrhea > or =7 days, emergency room visit or hospitalization, and antibiotic treatment) were statistically significant but colinear factors associated with reactive arthritis. Increased awareness of postdysenteric reactive arthritis and Reiter's syndrome is recommended.
