Active, not recruiting
Conditions
Histiocytosis
Interventions
Behavioral: Trail Making Test, Parts A & B
Behavioral: Brief Test of Attention
Behavioral: Symbol Span
Behavioral: Controlled Oral Word Association Test
Behavioral: The Hopkins Verbal Learning Test-Revised
Behavioral: Brief Visuospatial Memory Test-Revised
Behavioral: Hospital Anxiety and Depression Scale

Registration Number
NCT03127709
Lead Sponsor

Brief Summary

The purpose of this study is to try to understand how histopcytosis can cause symptoms or problems in the brain. The tests being done in the study will look at memory and thinking as well as brain function via MRI scan.

Exclusion Criteria
  • Known intracranial involvement of histiocytosis (including dura, leptomeninges and brain parenchyma)

  • Existing diagnosis of a neurodegenerative disease, such as Alzheimer's disease
  • Chronic or daily excessive alcohol consumption as determined by the PI.
  • History of chronic use of corticosteroids, defined as continuous treatment for six months or longer at any time in the past
  • History of severe claustrophobia or other contraindications to patient SOC brain MRI
  • Prior intravenous cytarabine or cladribine
  • Other current or prior treatments (e.g., high-dose chemotherapy for a different cancer) deemed by the PI or Co-PI to confound imaging studies or cognitive performance

Primary Outcome Measures
NameTimeMethod
neurocognitive function1 year

Neurocognitive tests will yield raw scores that are converted to z-scores, normalized for participant's age, sex and educational level.The proportion of participants demonstrating cognitive impairment (as defined by 2 or more z-scores less than -1.5) will be summarized. Also, the proportion of participants with impairment (z \< -1.5) for each cognitive test will be summarized. In this way the cognitive assessment yields a dichotomous outcome of impaired versus not impaired for each participant but also allow for more granular assessment of impairment in specific cognitive domains.

quality of life1 year

questionnaires will yield raw scores (total score for HADS and McGill QOL, as well as anxiety and depression subscores for the HADS). QOL scores will be analyzed as raw scores. Cognitive test scores will be transformed into z-sores (based on score distributions from established normative samples with a mean of 0 and standard deviation of 1) to define the presence/severity of cognitive dysfunction. Scores will be normalized for age, sex and education.

comparing of grey matter volume1 year

In a whole-brain analysis, first, cortical thickness will be compared between participants and controls and regions of statistically significant grey matter loss will be identified. This is done computionally with a whole-brain, vertex-by-vertex approach, as stated above. Also, as stated above (Section 7), statistical significance thresholding is at p\<0.001, correcting for multiple comparisons using the False Discovery Rate (FDR) method and clustering thresholds, methods used in various high-throughput contexts, including MRI analysis.
