Obsessive Compulsive Disorder associated with Autoimmunity in Youth: Clinical Course before and after Rituximab+/- Adjunctive Immunomodulation
Frankovich J, Calaprice D, Ma M, Knight O, Miles K, Manko C, Hernandez JD, Sandberg J, Farhadian B, Xie Y, Silverman M, Madan J, Strand V, Chang K, Thienemann M. Obsessive Compulsive Disorder associated with Autoimmunity in Youth: Clinical Course before and after Rituximab+/- Adjunctive Immunomodulation. Dev Neurosci. 2025 Mar 10:1-26. doi: 10.1159/000544993. Epub ahead of print. PMID: 40064151.
  • Case review (n=23) from Stanford on their use of rituximab for presumed-neuroimmune and severe OCD in youth
  • Some (47.8%) experienced transient increases in psychiatric or joint pain symptoms before signs of improvement. The time frame for signs of improvement was 3-4 months. 
  • 70% achieved full or partial recovery at 1-5 years.
  • Receiving adjunct immunomodulation was associated with a higher likelihood of achieving full or partial recovery compared with those without adjunct immunomodulation
Obsessive Compulsive Disorder and Other Specified Anxiety Disorder in an 8-Year-Old Post-respiratory Infection: A Case Report

Tran, Michael; Amador, Alcides; and Camacho Bermudez, Sofia, “Obsessive Compulsive Disorder and Other Specified Anxiety Disorder in an 8-Year-Old Post-respiratory Infection: A Case Report” (2024). Research Colloquium. 91.https://scholarworks.utrgv.edu/colloquium/2024/posters/91

Conclusions: This case underscores the importance of considering infectious etiologies in the differential diagnosis of sudden-onset psychiatric symptoms in pediatric patients. The positive response to Sertraline and the proposed CBT highlights the potential benefits of a combined pharmacological and therapeutic approach in managing OCD and anxiety disorders. Continued follow-up and treatment adaptation is essential to ensure sustained improvement and quality of life for pediatric patients with similar presentations.

A population-based multigenerational family co-aggregation study of severe infections and obsessive-compulsive disorder

Pol-Fuster J., Fernández de la Cruz L., Beucke J., Hesselmark E., Crowley J.J., de Schipper E., Brikell I., Chang Z., D’Onofrio B.M., Larsson H., Lichtenstein P., Kuja-Halkola, R. & Mataix-Cols D., A population-based multigenerational family co-aggregation study of severe infections and obsessive-compulsive disorder, Biological Psychiatry (2024), doi: https://doi.org/10.1016/ j.biopsych.2024.09.004.

This large population-based study in Sweden investigated the potential link between severe infections and obsessive-compulsive disorder (OCD) through a familial co-aggregation approach. By analyzing data from over 4.9 million individuals born between 1960 and 2008, researchers explored the risk of OCD among relatives of those with severe infections, spanning varying degrees of genetic relatedness. The study found that the risk of OCD increased with closer genetic ties, with monozygotic twins showing the highest correlation. A dose-response relationship between the number of infections and the odds of OCD was also identified. These findings remained robust even after adjusting for comorbid autoimmune disorders and infections in relatives. The results suggest that genetic factors play a significant role in the observed association, pointing to shared genetic susceptibilities between infections and OCD. This supports the idea that genetic pleiotropy—where the same genes influence multiple traits—may contribute to both infection susceptibility and OCD risk. The study highlights the importance of considering both genetic and environmental factors in understanding OCD development.

Elevated levels of neutrophil gelatinase-associated lipocalin among OCD patients: an exploratory study

Raposo-Lima, C., Pereira, I.M., Marques, F. et al. Elevated levels of neutrophil gelatinase-associated lipocalin among OCD patients: an exploratory study. BMC Psychiatry 21, 272 (2021). DOI: 10.1186/s12888-021-03289-w

“Although PANDAS might be of relevance for only a minor proportion of OCD cases, this immune/inflammation hypothesis may be significant given the prevalence of OCS among patients with autoimmune diseases [9]…. In conclusion, we herein report differences in NGAL levels among OCD patients compared to healthy controls. We offer additional evidence to the immune dysregulation hypothesis of OCD by reporting elevated levels of NGAL among OCD patients versus healthy controls, with higher differences being found among women”
