Objective: Certain cases of anorexia nervosa (AN) may be similar to the recently described subtype of childhood-onset obsessive-compulsive disorder hypothesized to be one of the pediatric infection-triggered autoimmune neuropsychiatric disorders (PITANDs). Method: Three clinical cases are reported. The first patient is a 12-year-old boy whose AN worsened acutely after a group A β-hemolytic streptococcal (GABHS) infection. His symptoms were alleviated after antibiotic treatment. Two other patients with possible PITANDs-related AN are described. Results: An infection-triggered process may contribute to the pathogenesis of a subtype of AN. Conclusions: Future research is needed to explore the nature of PITANDs and their relationship with AN.
