Association of Exposure to Infections in Childhood With Risk of Eating Disorders in Adolescent Girls
Breithaupt L, Köhler-Forsberg O, Larsen JT, Benros ME, Thornton LM, Bulik CM, Petersen L. Association of Exposure to Infections in Childhood With Risk of Eating Disorders in Adolescent Girls. JAMA Psychiatry. 2019 Aug 1;76(8):800-809. doi: 10.1001/jamapsychiatry.2019.0297. Erratum in: JAMA Psychiatry. 2019 May 8;: PMID: 31017632; PMCID: PMC6487907.

In a Danish population-based cohort study of 525 643 adolescent girls, a prior infection in childhood was associated with an increased risk of later anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified.

The findings suggest that hospital-treated infections and less severe infections treated with anti-infective agents are associated with increased risk of subsequent anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified and that future studies should investigate whether these associations are causal and identify the exact mechanisms between infections and subsequent inflammatory processes with eating disorders.

Immunoneuropsychiatry: novel perspectives on brain disorders

  • Chronic inflammation and latent infections can cause higher-order network disturbances, resulting in cognitive and behavioural impairment.
  • Psychosocial stress correlates with inflammatory processes in the CNS.
  • Immune dysregulation plays a key role in psychiatric disorders
  • Immune treatments are emerging as therapeutic options
A minority of children diagnosed with Lyme disease recall a preceding tick bite
Nigrovic LE, Neville DN, Balamuth F, Bennett JE, Levas MN, Garro AC; for Pedi Lyme Net. A minority of children diagnosed with Lyme disease recall a preceding tick bite. Ticks Tick Borne Dis. 2019 Apr;10(3):694-696. doi: 10.1016/j.ttbdis.2019.02.015. Epub 2019 Feb 26. PMID: 30853264.

Out of 1770 children evaluated in the emergency department for Lyme disease, 362 (20.5%) were diagnosed with the condition. Among those with a documented tick bite history, only a small percentage (18.5%, 95% confidence interval 14.6-23.0%) of Lyme disease cases were associated with a recognized tick bite. Therefore, the absence of a tick bite history does not reliably rule out Lyme disease.

Family Quality of Life When Raising a Child with Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infection (PANDAS)
Barbara B. Demchick, Julia Ehler, Shelly Marramar, Alison Mills & Amanda Nuneviller (2019) Family Quality of Life When Raising a Child with Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infection (PANDAS), Journal of Occupational Therapy, Schools, & Early Intervention, 12:2, 182-199, DOI: 10.1080/19411243.2019.1592052

“PANDAS is characterized by rapid onset of Obsessive Compulsive Disorder and/or tics following streptococcal infection in a previously healthy child. PANDAS is frequently misdiagnosed and misunderstood, which affects family quality of life (FQOL). A qualitative phenomenological design was used to examine FQOL in six families with a child with PANDAS. Data were collected through an audiotaped semi-structured interview and a phone interview to confirm findings. After rigorous data analysis, five themes emerged: Life Suddenly Turned Upside Down, My Child is Not Crazy, Emotional Distress within the Family, Major Life Alteration, and School Drastically Influences FQOL. Findings suggest that occupational performance and FQOL are severely restricted when a child has PANDAS. Implications for occupational therapy are discussed.”

Autoimmune Diseases and Psychotic Disorders

The increasing knowledge on the potential involvement of inflammatory processes in mental disorders and the associations found between autoimmunity and psychotic disorders can help the expanding field of immuno-psychiatry and have impact on the outcome of patients. In the last couple of years, researchers have focused on the role of infections, autoantibodies and other immune components that plays a major role in autoimmune diseases. Potentially this might also be the case for mental disorders.
