Analysis of Neuropsychiatric Diagnoses After Montelukast Initiation.

ABSTRACT:

Importance

The evidence base for the association between montelukast and adverse neuropsychiatric outcomes is mixed and inconclusive. Several methodological limitations have been identified in the evidence base on the safety of montelukast in observational studies.

Objective

To investigate the association between new montelukast exposure and 1-year incident neuropsychiatric diagnoses with improved precision and control for baseline confounders.

Design, setting, and participants

This propensity score-matched cohort study was conducted using electronic health records from 2015 to 2019 in the TriNetX Analytics Network patient repository of more than 51 million patients from 56 health care organizations, mainly in the US. Included patients were those aged 15 to 64 years at index prescription for montelukast or for control prescription who had a history of asthma or allergic rhinitis. After propensity score matching for various baseline confounders, including comorbidities and dispensed prescription medicines, we included 154 946 patients, of whom 77 473 individuals were exposed to montelukast. Patients were followed up for 12 months. Data were analyzed from June through November 2021.

Exposures

New dispensed prescription for leukotriene receptor antagonist montelukast or control medication.

Main outcomes and measures

Incident neuropsychiatric diagnoses at 12 months identified using International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes.

Results

There were 72 490 patients with asthma (44 726 [61.7%] women; mean [SD] age at index prescription, 35 [15] years) and 82 456 patients with allergic rhinitis (54 172 [65.7%] women; mean [SD] age at index prescription, 40 [14] years). In patients exposed to montelukast, the odds ratio [OR] for any incident neuropsychiatric outcome was 1.11 (95% CI, 1.04-1.19) in patients with asthma and 1.07 (95% CI, 1.01-1.14) in patients with allergic rhinitis compared with patients who were unexposed. The highest OR was for anxiety disorders (OR, 1.21; 95% CI, 1.05-1.20) among patients with asthma exposed to montelukast and insomnia (OR, 1.15; 95% CI, 1.05-1.27) among patients with allergic rhinitis exposed to montelukast.

Conclusions and relevance

This study found that patients with asthma or allergic rhinitis had increased odds of adverse neuropsychiatric outcomes after montelukast initiation. These findings suggest that clinicians should consider monitoring potential adverse mental health symptoms during montelukast treatment, particularly in individuals with a history of mental health or sleep problems.

Project description:ImportanceUnderstanding associations of Alzheimer disease (AD) and related dementias (ADRD) pathologies with common neuropsychiatric symptoms (NPS) may have implications for diagnosis and management.ObjectiveTo evaluate ADRD neuropathological diagnoses and NPS without consideration of clinical diagnosis.Design, setting, and participantsThis retrospective cohort study evaluated 1808 brains from 39 sites in the US National Alzheimer Coordinating Center v. 10 collection for participants among whom the Neuropsychiatric Inventory Questionnaire (NPIQ) was administered annually. Brain autopsy diagnoses of AD, Lewy body disease (LBD), cerebral amyloid angiopathy, frontotemporal lobar degeneration, cerebrovascular disease, hippocampal sclerosis, and no known pathology were examined. Autopsy data collected from January 2012 to January 2018 were deidentified and compiled into the publicly available v. 10 database. Data were analyzed from February 2021 to August 2021.Main outcomes and measuresThe primary outcome was NPIQ domain score, if present at any time point, and mean NPIQ domain score during follow-up was secondary. Associations of ADRD diagnoses with 12 NPIQ symptom domains were examined in regression analyses, correcting for multiple comparisons.ResultsThe study sample of 1808 adults had a mean (SD) age of 80.0 (11.0) years, and 987 participants (54.6%) were male. Apathy was the most prevalent NPS, reaching 80% (203 of 254 individuals) in those with hippocampal sclerosis. Cerebrovascular disease showed few NPS associations. Frontotemporal lobar degeneration was associated with increased apathy, increased disinhibition, and decreased psychosis and agitation compared with AD. Hippocampal sclerosis was associated with increased apathy (odds ratio, 2.60; 95% CI; 1.86-3.66, false discovery rate controlled P < .001) and disinhibition (odds ratio, 2.15; 95% CI, 1.63-2.84; false discovery rate controlled P < .001). In multiple regression analyses that included concomitant neuropathologies, the main findings remained. More severe pathology was consistently associated with increased NPS (eg, LBD was associated with an increase in hallucinations from brain stem [β, 0.23; 95% CI, 0.07-0.76; P = .02] to limbic [β, 1.69; 95% CI, 1.27-2.27; P < .001] to neocortical [β, 4.49; 95% CI, 3.27-6.16; P < .001] pathology). Hallucinations were more common in participants with AD and LBD (168 of 534 [31.5%]) compared with those with AD without LBD (152 of 704 [21.6%]) and those with LBD without AD (23 of 119 [19.6%]).Conclusions and relevanceIn this cohort study of 1808 brains from the US National Alzheimer Coordinating Center, patients with LBD and AD showed a higher prevalence of hallucinations compared with those with LBD without AD. Neuropsychiatric symptom criteria of apathy and disinhibition in behavioral variant frontotemporal lobar degeneration were supported in this study. In hippocampal sclerosis, the findings of increased apathy and disinhibition merit further investigation. Severity of neuropathology was associated with NPS severity, indicating that NPS may reflect underlying ADRD pathology and highlighting the importance of diagnosing and treating NPS.

Project description:BackgroundInfertility history may have important implications for clinical practice and scientific discovery. Previous research on the validity of self-reported infertility measurements has been limited in scope and duration (< 5 years). In this study, we validated self-reported infertility history measures 15-23 years after fertility treatment initiation among women who utilized assisted reproductive technology (ART).MethodsWomen who received ART treatments from three Boston infertility clinics and who enrolled in a prior study (1994-2003) were re-contacted in 2018 for the AfteR Treatment Follow-up Study (ART-FS). Infertility history was collected from clinical records and two self-report questionnaires (at ART initiation and at ART-FS enrollment). Treatment history included specific details (fresh or frozen embryo transfers, number of cycles) and treatment recall prior to ART initiation. Self-reported infertility diagnoses included polycystic ovary syndrome (PCOS), endometriosis, uterine factor infertility, tubal factor infertility, diminished ovarian reserve/advanced maternal age, male factor infertility, and other/unknown. We compared self-reported measures from 2018 to self-reported and clinical data from prior study initiation, using Cohen's kappa, sensitivity, specificity, and 95% confidence intervals.ResultsOf 2644 women we attempted to recontact, 808 completed the ART-FS, with an average follow-up of 19.6 years (standard deviation: 2.7). Recall of fertility treatment usage had moderate sensitivity (IVF = 0.85, Clomiphene/Gonadotropin = 0.81) but low specificity across different infertility treatment modalities (IVF = 0.63, Clomiphene/Gonadotropin = 0.55). Specific IVF details had low to moderate validity and reliability with clinical records. Reliability of recalled infertility diagnosis was higher when compared to self-report at ART initiation (PCOS K = 0.66, Endometriosis K = 0.76, Tubal K = 0.73) than when compared to clinical records (PCOS K = 0.31, Endometriosis K = 0.48, Tubal K = 0.62) and varied by diagnosis.ConclusionsThe ability of women to recall specific IVF treatment details was moderately accurate and recall of self-reported infertility diagnosis varied by diagnosis and measurement method.

Project description:BackgroundOur goal in this study was to identify paths from APOE e4 to neurobehaviors itemized on a neuropsychiatric inventory that involved neuropathologies associated with e4 (amyloid, tau, cerebral amyloid angiopathy, and Lewy bodies) or cognition mediators (memory or global cognitive status), as well as direct paths from e4 to cognition or neurobehaviors.MethodsA total of 1199 cases with available neurobehavioral, cognition and neuropathological data were included. We then conducted a series of causal mediation analyses in R in which e4 always served as the independent variable and Neuropsychiatric Inventory (NPI) neurobehavioral items, when included in the mediation, the outcome. Neuropathologies or cognition served as mediators.ResultsMultiple significant indirect paths from e4 through neuropathologies to neurobehaviors were identified. More refined analyses indicated that neuritic plaques and Braak stage, but not extent of diffuse amyloid plaques, drove the findings. A significant direct effect of e4 to memory was also identified. Additionally, Lewy body disease, when treated as an exposure, had a direct effect on hallucinations in keeping with known features of the disease.ConclusionsWe found strong evidence for partial mediation of NPI symptoms by cognition, suggesting that cognitive limitations that may have influenced understanding (or misunderstanding) the environment with impacts on maladaptive behavior. In addition, neuritic amyloid plaque levels and Braak stage, but not diffuse amyloid plaque extent, were key in NPI mediated associations suggesting the possibility that synaptic failure play an important role in multiple neurobehavioral symptoms in dementia, including psychosis. Last, we found strong evidence that e4 may have direct effects on cognition when we used verbal episodic memory as an outcome, suggesting that medial temporal regions that support memory may be sensitive to non-amyloidogenic and non-tau related pathophysiological processes.
