RESUMO
BACKGROUND: Acitretin has been linked to the development of psychiatric disturbance. OBJECTIVES: The aim of this study was to assess the psychiatric hazards in patients with psoriasis prescribed acitretin compared with those prescribed disease-modifying antirheumatic drugs (DMARDs). METHODS: This is a nationwide matched cohort study. From Taiwan's National Health Insurance Research Database, adult patients with psoriasis between 1997 and 2013 were screened. Patients prescribed acitretin for at least 30 days per year on average (acitretin cohort) were matched 1:2 with those prescribed DMARDs for at least 30 days per year on average (reference cohort), by means of age, gender, and psoriasis duration. Patients prescribed medication of the corresponding cohort for more than 7 days during the observation period were excluded. Cumulative incidences of psychiatric disorders in both cohorts were plotted with the Kaplan-Meier method. The modified Cox regression models were constructed to estimate hazard ratios (HRs). RESULTS: In total, 1,152 and 2,304 patients in the acitretin and the reference cohorts, respectively, were included. The 4-year cumulative incidence of overall psychiatric disorders (19.62% vs. 12.06%; p < 0.001), mood disorders (12.81% vs. 7.67%; p < 0.001), and psychosis (7.21% vs. 4.63%; p < 0.001) in the acitretin cohort was significantly higher than that in the reference cohort. Acitretin was independently associated with psychiatric disorders (HR 1.51, 95% confidence interval [CI] 1.23-1.85). The risk is more accentuated in the subgroups of comorbid chronic liver disease (HR 2.60, 95% CI: 1.56-4.33) or psoriatic arthritis (HR 3.23, 95% CI: 1.75-5.97). Other independent risk factors included insomnia, acute coronary syndrome, females, and age. CONCLUSIONS: Compared with DMARDs, acitretin was associated with higher hazards of psychiatric disorders among psoriasis patients.

We present a case involving a 60-year-old man with subacute delirium characterized by challenging attention shifts and obstinate behavior, contrasting with his usual mild-mannered personality. The patient developed pneumonia and a urinary tract infection following the onset of subacute delirium. Despite exhaustive investigations, the cause remained elusive until cerebrospinal fluid analysis revealed Tau positivity. Our overview suggests neurodegenerative diseases as the primary cause, rather than infectious or autoimmune factors. The case underscores a significant association between Tau and delirium superimposed on dementia, offering guidance to clinicians managing such patients.
RESUMO
OBJECTIVE: : The relationship of antipsychotics and the risk of refracture in treated patients is unclear. The aim of this study is to evaluate the association between prolonged antipsychotic and the incidences of bone fractures and refractures in schizophrenia. METHODS: This is a retrospective nested case-control study using Taiwan National Health Insurance Research Database recorded from 2000 to 2005, with cases followed up to end of 2011. Total of 7,842 schizophrenic patients, 3,955 had developed bone fractures were compared with 3,887 control subjects matched in age, sex, and index date. Antipsychotic drug exposure was classified based on the drug type and medication duration. Conditional logistic regression analyses were performed. Odds ratio (OR) and confidence interval (CI) were calculated. RESULTS: We found (after adjustments) higher risks of developing fractures under continued use of typical (OR = 1.70; 95% CI, 1.51-1.91) or atypical antipsychotics (OR = 1.43; 95% CI, 1.28-1.60) were found. Additionally, continued use typical (OR = 1.84; 95% CI, 1.35-2.50) or atypical antipsychotics (OR = 1.44; 95% CI, 1.06-1.95) was positively associated with refracture risks. Moreover, refractures were associated with continuous use of chlorpromazine (one typical antipsychotics, OR = 2.45; 95% CI, 1.14-5.25), and risperidone (OR = 1.48; 95% CI, 1.01-2.16) or zotepine (OR = 2.15; 95% CI, 1.06-4.36) (two atypical antipsychotics). CONCLUSION: Higher risks of bone fracture and refracture were found in schizophrenia under prolonged medication with typical or atypical antipsychotics. We therefore recommend that clinicians should pay more attention on bone density monitoring for patients using long-term antipsychotics.
