Horowitz RI, Freeman PR. Precision medicine: retrospective chart review and data analysis of 200 patients on dapsone combination therapy for chronic Lyme disease/post-treatment Lyme disease syndrome: part 1. Int J Gen Med. 2019 Feb 18;12:101-119. doi: 10.2147/IJGM.S193608. PMID: 30863136; PMCID: PMC6388746.
Diaminodiphenyl sulfone (DDS CT) decreased eight major Lyme symptoms severity and improved treatment outcomes among patients with chronic Lyme disease/PTLDS and associated coinfections.
Maternal thyroid autoimmunity associated with acute-onset neuropsychiatric disorders and global regression in offspring
Jones HF, Ho ACC, Sharma S, Mohammad SS, Kothur K, Patel S, Brilot F, Guastella AJ, Dale RC; Immune-Neurodevelopment (Imm-Nd) Study Group. Maternal thyroid autoimmunity associated with acute-onset neuropsychiatric disorders and global regression in offspring. Dev Med Child Neurol. 2019 Aug;61(8):984-988. doi: 10.1111/dmcn.14167. Epub 2019 Feb 5. PMID: 30720202.

Abstract: Epidemiological studies, animal models, and case–control studies indicate maternal immune activation may be an important factor involved in disease expression of autism spectrum disorder (ASD), Tourette syndrome, and obsessive–compulsive disorder (OCD). We report eight children (mean age 6y 6mo [range 4–15y]; six males and two females) referred over a 2‐year period with at least one of these neurodevelopmental disorders plus a maternal history of thyroid autoimmunity…

PANDAS and PANS: Clinical, Neuropsychological, and Biological Characterization of a Monocentric Series of Patients and Proposal for a Diagnostic Protocol

Gamucci A, Uccella S, Sciarretta L, D’Apruzzo M, Calevo MG, Mancardi MM, Veneselli E, De Grandis E.
J Child Adolesc Psychopharmacology-2019

Conclusions: Despite these limitations, this study presents clinical, biological, and psychological features of a group of patients fulfilling the PANS and PANDAS criteria and discusses these results in comparison with patients with SC, a well-established clinical condition. Moreover, it adds notable findings to the existing little literature on neuropsychological functioning in youth diagnosed with these disorders, in particular PANS and PANDAS…

Psychometric Properties of the Pediatric Acute-Onset Neuropsychiatric Syndrome Global Impairment Score in Children and Adolescents with Pediatric Acute-Onset Neuropsychiatric Syndrome

J Child Adolesc Psychopharmacololgy-2019

Results: The GIS shows excellent discriminant validity, distinguishing patients with PANS from healthy controls. The scores on the GIS show an acceptable level of agreement with the clinician-reported CGAS. The regression line in the Bland–Altman plot had a positive slope, indicating that parents tend to report higher disease severity than clinicians at higher levels of disease severity. Correlation was higher during disease remissions than during disease flares (r = −0.69 vs. r = −0.48). All disease severity scales predicted GIS in the expected direction

As representatives of the pediatric acute-onset neuropsychiatric syndrome (PANS)/pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) organizations in Europe, we have concerns about the commentary by Gilbert et al,1 given its potential to negatively influence the treatment of children suffering from these devastating conditions.

Reduction in Obsessive Compulsive Disorder and Self-Injurious Behavior With Saccharomyces boulardii in a Child with Autism: A Case Report
Kobliner V, Mumper E, Baker SM. Reduction in Obsessive Compulsive Disorder and Self-Injurious Behavior With Saccharomyces boulardii in a Child with Autism: A Case Report. Integr Med (Encinitas). 2018 Dec;17(6):38-41. PMID: 31043927; PMCID: PMC6469440.

This case report describes the effective use of Saccharomyces boulardii in a boy with autism spectrum disorder, obsessive compulsive disorder (OCD), and self-injurious behavior (SIB). Gastrointestinal dysfunction and OCD are frequent comorbidities in autism, which may share a common etiology resulting from a disturbance in normal gut microbiota. Alterations in microbial diversity influence neuroinflammation and are linked to mood disorders, abdominal pain, and SIB. S boulardii is a nonpathogenic probiotic yeast that supports a healthy microbiome, enhances immune function, and reduces diarrhea. Treatment with S boulardii successfully reduced OCD and SIB symptoms in this child.

The Burden of Caring for a Child or Adolescent With Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS): An Observational Longitudinal Study

Conclusions: PANS caregivers suffer high caregiver burden. Neuropsychiatric disease severity predicts increased caregiver burden. Caregiver burden tends to decrease over time in a group of patients undergoing clinical treatment at a specialty PANS clinic. This decrease could be independent of clinical treatment.

Precision Medicine: The Role of the MSIDS Model in Defining, Diagnosing, and Treating Chronic Lyme Disease/Post Treatment Lyme Disease Syndrome and Other Chronic Illness: Part 2
Horowitz RI, Freeman PR. Precision Medicine: The Role of the MSIDS Model in Defining, Diagnosing, and Treating Chronic Lyme Disease/Post Treatment Lyme Disease Syndrome and Other Chronic Illness: Part 2. Healthcare (Basel). 2018 Nov 5;6(4):129. doi: 10.3390/healthcare6040129. PMID: 30400667; PMCID: PMC6316761.
A patient symptom survey and a retrospective chart review of 200 patients was therefore performed on those patients with chronic Lyme disease/PTLDS to identify those variables on the MSIDS model with the greatest potential effect on regaining health. Results indicate that dapsone combination therapy decreased the severity of eight major Lyme symptoms, and multiple sources of inflammation (other infections, immune dysfunction, autoimmunity, food allergies/sensitivities, leaky gut, mineral deficiencies, environmental toxins with detoxification problems, and sleep disorders) along with downstream effects of inflammation may all affect chronic symptomatology. In part two of our observational study and review paper, we postulate that the use of this model can represent an important and needed paradigm shift in the diagnosis and treatment of chronic disease.

C-Reactive Protein Response in Patients With Post-Treatment Lyme Disease Symptoms Versus Those With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

The data suggest the presence of different inflammatory mechanisms in ME/CFS compared to PTLDS. This difference may stem from the potentially more diverse causes of ME/CFS symptoms compared to PTLDS. The lack of a significantly elevated CRP response in ME/CFS, despite indications of activation in other inflammatory pathways, requires further investigation.
