    BACKGROUND: Increased cancer risk has been reported in Parkinson's disease (PD) patients carrying the leucine rich repeat kinase 2 (LRRK2) G2019S mutation (LRRK2-PD) in comparison with idiopathic PD (IPD). It is unclear whether the elevated risk would be maintained when compared with unaffected controls. METHODS: Cancer outcomes were compared among 257 LRRK2-PD patients, 712 IPD patients, and 218 controls recruited from 7 LRRK2 consortium centers using mixed-effects logistic regression. Data were then pooled with a previous study to examine cancer risk between 401 LRRK2-PD and 1946 IPD patients. RESULTS: Although cancer prevalence was similar among LRRK2-PD patients (32.3%), IPD patients (27.5%), and controls (27.5%; P = 0.33), LRRK2-PD had increased risks of leukemia (odds ratio [OR] = 4.55; 95% confidence interval [CI], 1.46-10.61) and skin cancer (OR = 1.61; 95% CI, 1.09-2.37). In the pooled analysis, LRRK2-PD patients had also elevated risks of leukemia (OR = 9.84; 95% CI, 2.15-44.94) and colon cancer (OR = 2.34; 95% CI, 1.15-4.74) when compared with IPD patients. CONCLUSIONS: The increased risks of leukemia as well as skin and colon cancers among LRRK2-PD patients suggest that LRRK2 mutations heighten risks of certain cancers. © 2019 International Parkinson and Movement Disorder Society.

    Pooled Phase 2 and 3 Efficacy and Safety Data on Budesonide Oral Suspension in Adolescents with Eosinophilic Esophagitis
    (Wolters Kluwer, 2023) Mukkada, Vincent A.; Gupta, Sandeep K.; Gold, Benjamin D.; Dellon, Evan S.; Collins, Margaret H.; Katzka, David A.; Falk, Gary W.; Williams, James; Zhang, Wenwen; Boules, Mena; Hirano, Ikuo; Desai, Nirav K.; Pediatrics, School of Medicine
    Objectives: The objective of this study was to evaluate the efficacy and safety of budesonide oral suspension (BOS) in adolescents with eosinophilic esophagitis (EoE). Methods: This post hoc analysis pooled data from two 12-week, randomized, double-blind, placebo-controlled studies of BOS 2.0 mg twice daily (b.i.d.) (phase 2, NCT01642212; phase 3, NCT02605837) in patients aged 11-17 years with EoE and dysphagia. Efficacy endpoints included histologic (≤6, ≤1, and <15 eosinophils per high-power field [eos/hpf]), dysphagia symptom (≥30% reduction in Dysphagia Symptom Questionnaire [DSQ] scores from baseline), and clinicopathologic (≤6 eos/hpf and ≥30% reduction in DSQ scores from baseline) responses at week 12. Change from baseline to week 12 in peak eosinophil counts, DSQ scores, EoE Histology Scoring System (EoEHSS) grade (severity) and stage (extent) total score ratios (TSRs), and total EoE Endoscopic Reference Scores (EREFS) were assessed. Safety outcomes were also examined. Results: Overall, 76 adolescents were included (BOS, n = 45; placebo, n = 31). Significantly more patients who received BOS than placebo achieved histologic responses (≤6 eos/hpf: 46.7% vs 6.5%; ≤1 eos/hpf: 42.2% vs 0.0%; <15 eos/hpf: 53.3% vs 9.7%; P < 0.001) and a clinicopathologic response (31.1% vs 3.2%; P = 0.003) at week 12. More BOS-treated than placebo-treated patients achieved a dysphagia symptom response at week 12 (68.9% vs 58.1%; not statistically significant P = 0.314). BOS-treated patients had significantly greater reductions in EoEHSS grade and stage TSRs ( P < 0.001) and total EREFS ( P = 0.021) from baseline to week 12 than placebo-treated patients. BOS was well tolerated, with no clinically meaningful differences in adverse events versus placebo. Conclusions: BOS 2.0 mg b.i.d. significantly improved most efficacy outcomes in adolescents with EoE versus placebo.
