Paediatric autoimmune neuropsychiatric disorders (PANDAS): A case report
Sankaranarayanan, Anoop & John, J. (2003). Paediatric autoimmune neuropsychiatric disorders (PANDAS): A case report. The National medical journal of India. 16. 22-3. Read report
In view of the early onset of obsessive symptoms with periodic sudden exacerbations interspersed with periods of partial remissions, and the past history of streptococcal throat infection, the possibility of PANDAS was considered (Table I). However, he did not exhibit any abnormal movement, although he seemed fidgety and restless (Swedo2 has described ‘squirminess’ in some patients). In addition, the ASO titre done at our hospital was negative. It is, however, well accepted that not all exacerbations are preceded by group A beta-haemolytic streptococci (GABHS) infections and a prospective follow up is required to establish this association.
Note: Neither tics nor abnormal movements are required for a PANS diagnosis.
The question of PANDAS in adults
Sara M Bodner, Syed A Morshed, Bradley S Peterson, The question of PANDAS in adults, Biological Psychiatry, Volume 49, Issue 9, 2001, Pages 807-810, ISSN 0006-3223, https://doi.org/10.1016/S0006-3223(00)01127-6.
We describe an adult with onset of obsessive–compulsive disorder at 25 years of age after a severe antibiotic-responsive pharyngitis. He was evaluated with multiple psychiatric rating scales for obsessive–compulsive disorder and Tourette’s syndrome, as well as with serologic assays and radiologic studies.
Results: In all respects except age our patient fulfilled established criteria for PANDAS. Assays for antibodies to group A β-hematolytic streptococci, serum D8,17 lymphocytes, antistriatal (neuronal) antibodies, and anticytoskeletal antibodies all supported the hypothesis that a poststreptococcal process was active. Magnetic resonance imaging was abnormal and is described.
Anorexia, OCD, and streptococcus
Case Study: A New Infection-Triggered, Autoimmune Subtype of Pediatric OCD and Tourette’s Syndrome
A review of clinical observations and literature reports leads to the hypothesis that, via a process analogous to Sydenham’s chorea, infections with group A β-hemolytic streptococci, among others, may trigger autoimmune responses that cause or exacerbate some cases of childhood-onset obsessive-compulsive disorder (OCD) or tic disorders (including Tourette’s syndrome).

Patient Vignette – Bicycle Boy
The patient was bitten by a tic. Weeks later he presented with neuropsychiatric symptoms. Was given IV antibiotics and all symptoms resolved.
Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections: clinical description of the first 50 cases
Results: The children’s symptom onset was acute and dramatic, typically triggered by GABHS infections at a very early age (mean = 6.3 years, SD = 2.7, for tics; mean = 7.4 years, SD = 2.7, for OCD). The PANDAS clinical course was characterized by a relapsing-remitting symptom pattern with significant psychiatric comorbidity accompanying the exacerbations; emotional lability, separation anxiety, nighttime fears and bedtime rituals, cognitive deficits, oppositional behaviors, and motoric hyperactivity were particularly common. Symptom onset was triggered by GABHS infection for 22 (44%) of the children and by pharyngitis (no throat culture obtained) for 14 others (28%). Among the 50 children; there were 144 separate episodes of symptom exacerbation; 45 (31%) were associated with documented GABHS infection, 60 (42%) with symptoms of pharyngitis or upper respiratory infection (no throat culture obtained), and six (4%) with GABHS exposure.
Conclusions: The working diagnostic criteria appear to accurately characterize a homogeneous patient group in which symptom exacerbations are triggered by GABHS infections. The identification of such a subgroup will allow for testing of models of pathogenesis, as well as the development of novel treatment and prevention strategies.
Clinical and diagnostic manifestations of tickborne mixed infection in combination with COVID-19
- The study investigated the coexistence of pathogens in a patient, focusing on the relationship between laboratory diagnostics and clinical manifestations during SARS-CoV-2 infection in a case of chronic encephalitis-borreliosis.
- Blood samples collected over a year revealed Lyme disease diagnosed through IgG antibodies to Borrelia, with joint pain and erythema migrans. Subsequently, the patient contracted SARS-CoV-2 during a Lyme disease exacerbation.
- Treatment improved the underlying disease but led to TBEV activation, possibly due to immune system focus on SARS-CoV-2. Despite TBEV activation, clinical manifestations were absent, suggesting weak virulence. Etiotropic treatment suppressing borreliosis led to TBEV activation, highlighting the dominance of B. burgdorferi in tick-borne infections.
