Abstract
Pediatric autoimmune neuropsychiatric disorders (PANDAS) and patient neuropsychiatric syndrome (PANS) are psychiatric illnesses characterized by a rapid onset of symptoms, including obsessive-compulsive disorder (OCD), behavioral symptoms and poor motor functions in children. The rapid onset and severity of OCD symptoms prompted investigations to provide an evidence-based intervention. This case series investigates the causes, diagnosis and treatment of the disease among children presenting with neuropsychiatric symptoms and acute-onset OCD. The diagnostic procedures provided grounds for the indication of medication. Methods: Bacterial infections, autoimmune cases and viral infections among 12 children with PANDAS and PANS were retrospectively studied. Pre- and post-treatment symptomatology were examined to monitor the effectiveness of interventions, following laboratory diagnostic approaches, including the Cunningham panel, serology, stool sample analysis, polymerase chain reaction (PCR), and bacterial cultures to determine the cause of the disorder. Diagnostic results informed treatments like non-steroidal anti-inflammatory drugs (NSAIDs), intravenous immunoglobulin (IVIG), fluid therapy, antibiotics, antivirals, steroids, and selective serotonin reuptake inhibitors (SSRIs) in each child. Post-treatment diagnostic results revealed remarkably improved symptoms of PANDAS and PANS, like inflammation and viral or bacterial infection. A combined therapy of antibiotics and NSAIDs or steroids was used to clear bacterial infections and manage inflammation. SSRIs and antiviral or fluid therapy were indicated for OCD and viral infections, respectively. Conclusions: OCD is a common comorbid disorder among children with PANS and PANDAS. Despite the severity and prevalence, OCD in children raises health concerns. The case series demonstrated the effectiveness of antibiotic therapy, RRIs, cognitive behavioral therapy, IVIG, steroids and NSAIDs in managing OCD in PANDAS and PANS, with a unique rationale of indication to every child.
