“…106 One study reported a nearly 10 prevalence of prolonged (.440 milliseconds) QTc interval in hospitalized adolescents and young adults with a restrictive eating disorder. 107 Repolarization abnormalities, a potential precipitant to lethal arrhythmia, 108 may prompt clinicians to also consider other factors, such as medication use or electrolyte abnormalities, that may affect cardiac conduction. 107,109 Gastrointestinal Tract Effects…”

Eating disorders are serious, potentially life-threatening illnesses afflicting individuals through the life span, with a particular impact on both the physical and psychological development of children and adolescents. Because care for children and adolescents with eating disorders can be complex and resources for the treatment of eating disorders are often limited, pediatricians may be called on to not only provide medical supervision for their patients with diagnosed eating disorders but also coordinate care and advocate for appropriate services. This clinical report includes a review of common eating disorders diagnosed in children and adolescents, outlines the medical evaluation of patients suspected of having an eating disorder, presents an overview of treatment strategies, and highlights opportunities for advocacy.

“…There are several studies focused on the QT interval in patients with AN and the results are inconsistent. QTc interval prolongation was observed in considerable amount of small studies [4,[14][15][16][17][18][19][20]. Majority of those study used only Bazett formula, which is highly dependent on heart rate [21].…”

“…It is reasonable to examine dietary idiosyncrasies and consider specific complications of nutritional deficiencies. In a small cohort of children with avoidant‐restrictive eating patterns, 10% had electrolyte abnormalities (Guerrier, Mitan, Wang, & Czosek, ) and ketogenic diets have been associated with magnesium wasting and hypomagnesemia in patients with intractable epilepsy (Kang, Chung, Kim, & Kim, ). Although this patient demonstrated a strong preference for high protein items, it is unlikely that her food preferences amounted to a sufficient ketogenic load to cause this complication.…”

We present a novel case of a woman with coincident occurrence of auditory and visual hallucinations, electrolyte disturbances, chloride unresponsive alkalosis, and an eating disorder. The patient was ultimately diagnosed with Gitelman syndrome comorbid with schizophreniform disorder and avoidant restrictive food intake disorder. Eating disorders are often associated with electrolyte abnormalities which, in turn, can cause or contribute to other neuropsychiatric symptoms. At the same time, psychotic disorders can lead to food intake aversions or overconsumption of fluids with associated effects on electrolyte balance. In this case, a third factor, Gitelman syndrome, resulted in persistent hypomagnesemia with metabolic alkalosis and, while separate from her eating disorder, simultaneously reinforced the patient's strong food preferences, excessive fluid intake, and excessive movement related to her complaints of persistent joint pain.

Risk for prolonged QT interval and associated outcomes in children with early restrictive eating patterns

Abstract: Mild QTc prolongation in patients with restrictive eating disorders is not related to electrolyte abnormalities or rate of weight loss in this population, suggesting that investigation about other potential risk factors of prolonged QTc interval may be warranted.
