Calaprice-Whitty D, Tang A, Tona J. Factors Associated with Symptom Persistence in PANS: Part I-Access to Care. J Child Adolesc Psychopharmacol. 2023 Nov;33(9):356-364. doi: 10.1089/cap.2023.0022. Epub 2023 Oct 30. PMID: 37902790.
- Greater symptom persistence correlated with longer intervals between symptom onset and treatment (F = 4.43, p = 0.002).
- Subjects with the least symptom persistence (>75% symptom-free days) were diagnosed by the first practitioner seen in 34% of cases, compared to 13% in those with the most persistent symptoms (symptoms every day) (L-R χ2 = 36.55, p < 0.0001).
- Lack of access to expertise did not impede diagnosis and treatment for 52% of subjects with the least persistent symptoms, contrasting with 22% in those with the most persistent symptoms (L-R χ2 = 22.47, p < 0.0001).
- Affordability did not impact diagnosis and treatment for 76% of subjects with the least persistent symptoms, whereas it affected 42% of those with the most persistent symptoms (L-R χ2 = 27.83, p < 0.0001).
- Subjects whose PANS symptoms resolved with antibiotic treatment had less symptom persistence than others (χ2 = 23.27, p = 0.0001).
- More persistently symptomatic subjects were more likely to discontinue intravenous immunoglobulin (IVIG) treatment due to access-to-care reasons.
“Conclusions: Unimpeded access to care for PANS is associated with more symptom-free days over reporting periods averaging approximately 4 years. Difficulty reaching expert providers, missed opportunities for diagnoses, and financial limitations may worsen outcomes. Practitioners, particularly primary providers, should adhere to published diagnostic and treatment guidelines promptly upon presentation.”
