This study serves as the first survey of its size to provide insight into the global clinical picture and range of phenotypes of PANS patients. Significant results included the impact of gender and pubertal status on phenotype, affirmation of the role of the immune system in PANS pathology, and the role of timely resolution of infection in clinical outcomes. Understanding how PANS presents in a broad population-based sample, within the limitations of a self-selected and administered online survey, is an important step toward improving diagnosis, creating more targeted treatment options, educating the clinical and research community, and generating hypotheses for future prospective research.
Objective: The goal of this study was to investigate treatment histories and outcomes in a large community sample of youth with Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), and, where appropriate, to examine the impact of immune deficiency on treatment outcomes.Methods: A comprehensive internet-based survey was completed by parents or guardians of youth who had received physician diagnoses of PANS, or by young adults (age 18+) who had themselves been diagnosed by a physician (N = 698). Data regarding the treatment histories of these patients, including the variety of medical and psychological treatments employed and the caregiver- or self-reported response to each, are presented.Results: The PANS patients in this study had commonly been treated with antibiotic (N = 675), anti-inflammatory (N = 437), and/or psychotropic therapy (N = 378). Response to antibiotic treatment was best when treatment was relatively aggressive, with broad-spectrum antibiotics and courses of >30 days generally producing the best results (i.e., up to 52% of patients achieving a “very effective” response). For immune-deficient patients (caregiver-reported laboratory studies below normal limits; N = 108), use of broad-spectrum antibiotics appeared to be particularly desirable. Anti-inflammatory therapies, including over-the-counter medications such as ibuprofen, were at least “somewhat effective” for most patients. Intravenous immunoglobulin (IVIG) had been used to treat PANS in 193 (28%) of the patients and was at least “somewhat effective” for 89%, although for 18% of these, the effect was not sustained. The highest rate of sustained response to IVIG treatment was seen in immune-deficient patients who received doses of at least 0.8 g/kg IVIG on a regular basis. Psychotropic medications, most commonly SSRIs (38% reported a trial), were commonly employed, but were often ineffective (e.g., 44% found SSRIs “somewhat” to “very effective”). Many patients (N = 473) had received some form of psychotherapy with some benefit, with cognitive behavioral therapy found to be at least somewhat effective in a majority of those treated with this modality.Conclusion: Among the PANS patients represented in this study, relatively aggressive treatment courses targeted at eradicating infection and modulating the inflammatory response appeared to provide the best caregiver-reported therapeutic results, and to be generally well tolerated. Given its relative efficacy and tolerability, treatment targeting the inflammatory response may represent an underutilized approach in this population. The results of this study should be considered in light of the limitations inherent in a self-selected and administered online survey.
This pilot study was designed to examine the effects of short-term (48-hr) upper extremity inhibitive casting, with an encased thermoplastic splint, on problems related to upper motor neuron damage. The subject was an 8 1/2-year-old girl with left upper extremity spasticity. Three different measures were used: (a) rating of videotaped active movements of the child; (b) the Modified Ashworth Scale, a clinical measure of spasticity; and (c) The Biodex System, a measure of torque during passive elbow flexion and extension. After cast removal, subjective improvements were noted in the quality of active movement (through videotapes) and increased awareness and use of the casted hand by the child (through parents' reports). A trend toward decreased spasticity was demonstrated by the Modified Ashworth Scale and a statistically significant decrease in resistance to passive movement was shown by the Biodex recordings. However, this reduction in symptoms was temporary, lasting less than 3 days. The results of this study suggest that short-term inhibitory casting may prove efficacious in the treatment of the child with cerebral palsy, although further research is needed.
Children with PANS present with pervasive occupational performance needs during exacerbation. Children and families may benefit from accommodations to maximize function during this turbulent period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
