RESUMO
INTRODUCTION: At present, increasing reports from different aspects indicated that cholinesterase inhibitors (ChEIs) may be effective on improving neuropsychiatric and functional assessment scores in patients with Alzheimer disease (AD). However, no studies comprehensively and detailedly evaluated the effect of ChEIs on AD. The present analysis was designed to comprehensively evaluate the efficacy and safety of ChEIs for AD. METHODS: Two independent researchers systematically reviewed 1096 searching records in PubMed, Embase, Cochrane Library, and Web of Science from inception to 10 May 2023, and finally identified 12 randomized, double-blind, placebo-controlled trials with 6908 participants according to predetermined inclusion and exclusion criteria. The effects were assessed with standardized mean difference (SMD) or odds ratio (OR). The primary outcomes were the mean change and least squares (LS) mean change from baseline to endpoint of neuropsychiatric and functional assessment scores. The secondary outcome was adverse events of ChEIs when compared to placebo for patients with AD. All statistical analyses were performed using the standard statistical procedures provided in Review Manager 5.2 and and Stata 12.0. RESULTS: Pooled analysis indicated that ChEIs significantly improved the assessment scores of the AD Assessment Scale (ADAS) (SMD -1.57; 95% CI: -2.64 to -0.51), Clinician's Interview-Based Impression of Change-Plus caregiver input (CIBIC-Plus) (SMD -0.28; 95% CI: -0.41 to -0.15), the Neuropsychiatric Inventory (NPI) (both SMD -1.67; 95% CI: -2.88 to -0.47 for 10-tiem total score and SMD -1.83; 95% CI: -3.25 to -0.42 for 12-tiem total score), and the AD Cooperative Study-Activities of Daily Living (ADCS-ADL) total score (SMD 2.44; 95% CI: 1.29-3.59), evaluated with mean change from baseline to endpoint. In addition, when evaluated with the LS mean change from baseline to endpoint, ChEIs significantly improved Mini-Mental State Examination (MMSE) total score, the Clinician Interview-Based Impression of Severity, CIBIC-Plus, ADCS-ADL total score, NPI, ADAS. Regarding to adverse events (AEs) of patients with AD, it indicated that compared to placebo, ChEIs did not increase the frequency of severe and serious AEs (fatal or nonfatal) as well as the incidence of death. CONCLUSIONS: Our analysis indicated that ChEIs treatment generally improved neuropsychiatric and functional assessment scores in patients with AD though opposite result was observed in Wechsler Memory Scale. ChEIs had an acceptable safety profile in patients with AD without increasing of any crucial adverse or outcomes.

Current drugs for Alzheimer's Disease (AD), such as cholinesterase inhibitors (ChEIs), exert only symptomatic activity. Different psychometric tools are needed to assess cognitive and non-cognitive dimensions during pharmacological treatment. In this pilot study, we monitored 33 mild-AD patients treated with ChEIs. Specifically, we evaluated the effects of 6 months (Group 1 = 17 patients) and 9 months (Group 2 = 16 patients) of ChEIs administration on cognition with the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), and the Frontal Assessment Battery (FAB), while depressive symptoms were measured with the Hamilton Depression Rating Scale (HDRS). After 6 months (Group 1), a significant decrease in MoCA performance was detected. After 9 months (Group 2), a significant decrease in MMSE, MoCA, and FAB performance was observed. ChEIs did not modify depressive symptoms. Overall, our data suggest MoCA is a potentially useful tool for evaluating the effectiveness of ChEIs.

Environmental screening is essential due to the increased occurrence of harmful substances in the environment. Open Meter Duo (OMD) is an open-source field photo/fluorimeter that uses an RGB diode that imitates a color according to the selected wavelength and uses a UV LED from the security kit diode as an excitation light source. The prepared PCB shield with a 3D-printed aperture was connected to Arduino UNO R4 WiFi. This system was used for the fluorescent detection of cholinesterase activity with the indoxyl acetate method. Carbofuran-a toxic pesticide-and donepezil-a drug used to treat Alzheimer's disease-were tested as model inhibitors of cholinesterase activity. The limit of detection of indoxyl acetate was 11.6 µmol/L, and the IC50 values of the inhibitors were evaluated. This system is optimized for wireless use in field analysis with added cloud support and power source. The time of analysis was 5 min for the fluorimetric assay and 20 min for the optional photometric assay. The time of field operation was approximately 4 h of continuous measurement. This system is ready to be used as a cheap and easy control platform for portable use in drug control and point-of-care testing.

INTRODUCTION/AIMS: Limited knowledge exists on treatment patterns in clinical practice in patients with myasthenia gravis (MG). In this study we examined MG treatment patterns in the United States. METHODS: Adult patients newly diagnosed with MG were identified from the IBM MarketScan insurance claims database. Patients with ≥2 MG International Classification of Disease diagnosis codes ≥3 months apart were retrospectively followed from the date of their first MG diagnosis record or start of treatment with acetylcholinesterase inhibitors (AChEI), intravenous (IV) or subcutaneous (SC) immunoglobulin (Ig), or plasma exchange (PLEx) therapy. Based on treatment received at any time during the follow-up period, patients were segmented into six main treatment cohorts. Exacerbations and use of IVIg, SCIg, or PLEx after the index date were identified. RESULTS: During 2010 to 2019, 7,194 patients were followed for up to 10 (median, 2.3) years. Of 6,539 treated patients, 6,462 (99%) were ever treated with AChEI and/or corticosteroids (CS); 95% were first treated with AChEI and/or CS only; 33% received ≥1 nonsteroid immunosuppressive treatment (IST) and 2% received a biologic. During treatment with first IST (n = 2,166), patients experienced 42% and 94% higher incidence rates of exacerbations and IVIg, respectively, compared with AChEI and/or CS (n = 6,242), and 33% and 23% higher, respectively, compared with a second IST (n = 353). DISCUSSION: Many patients experienced exacerbations and received rescue therapy despite treatment, suggesting current treatments may not provide adequate disease control for some patients and that additional treatment options should be explored.

BACKGROUND: Polypharmacy may result from inappropriate prescribing of medications to treat adverse drug reactions (ADRs), i.e., "prescribing cascade." A potentially harmful prescribing cascade affecting those with severe dementia can result when anticholinergics are prescribed to manage side effects of cholinesterase inhibitors (ChEIs). We investigated 1) factors associated with co-prescribing of anticholinergics and ChEIs and 2) whether discontinuation of ChEIs was associated with subsequent discontinuation of anticholinergics-a potentially beneficial reversal or "deprescribing cascade." METHODS: We conducted a retrospective analysis of linked Medicare Part A/B/D claims, Master Beneficiary Summary File, Minimum Data Set, Area Health Resource File, and Nursing Home Compare from 2015 to 2016. Subjects were Medicare beneficiaries residing in nursing homes, ≥65 years old with severe dementia admitted for non-skilled stays, who were prescribed ChEIs. Cross-sectional analysis evaluated factors associated with co-prescribing of anticholinergics with ChEIs. Longitudinal Cox proportional hazards regression examined whether discontinuation of ChEIs was associated with subsequent discontinuation of anticholinergics over a 1-year period. RESULTS: We found 15% of our sample experienced co-prescribing of anticholinergics and ChEIs. Several resident and facility-level factors were associated with co-prescribing anticholinergics. Advancing age, minority race or ethnicity, end-stage renal disease, heart failure, and poor appetite were associated with a decreased likelihood of co-prescribing. Female sex, polypharmacy, and non-geriatric prescriber-type were associated with a higher likelihood of co-prescribing. In longitudinal analyses, we observed that discontinuation of ChEIs was associated with a reduced likelihood (HR 0.58 [95% CI, 0.47-0.71]) of discontinuing any medications with anticholinergic properties, except for bladder antimuscarinics (HR 1.32 [95% CI, 0.83-2.09]). CONCLUSIONS: Younger, healthier older adults with dementia were more likely to experience co-prescribing anticholinergics and ChEIs. Discontinuation of anticholinergics was infrequent. Further research is needed to understand prescribers' ability to recognize and reverse potential prescribing cascades through deprescribing.

BACKGROUND: With a growing elderly population worldwide, the prevalence of dementia is rapidly increasing. Studies from high income countries have shown that belonging to a minority ethnic group increases the risk of health disadvantages. OBJECTIVE: The aim of the present registry-based study was to identify potential differences in diagnostics, treatment, and care of individuals with dementia focusing on foreign-born in Sweden and the impact of country level socioeconomic position (SEP). METHODS: The study was based on a large dataset from the Swedish Dementia Registry (SveDem) and the Swedish Tax Agency's population registry. Data on demographic variables, cognitive tests, clinical assessments, medication, diagnosis, and interventions initiated at diagnosis were collected. Country level SEP was determined by country of birth as classified by World Bank Country and Lending groups. RESULTS: Of 57,982 patients with dementia registered in SveDem, 7,171 (12.4%) were foreign-born. The foreign-born were significantly younger at diagnosis (pâ<â0.001), had a lower MMSE score (pâ<â0.001), lower odds of receiving a specific dementia diagnosis (pâ<â0.001), lower use of acetylcholinesterase inhibitors (pâ<â0.001), and overall a higher use of neuroleptics compared with the Swedish-born group. The lower SEP, the greater differences to Swedish-born were seen in many of the examined variables. CONCLUSION: There were significant differences in dementia diagnostics, treatment, and care between foreign-born and Swedish-born, a lower SEP indicating greater differences. Further research should focus on various socioeconomic aspects and health care outcomes for a more profound analysis of equity in dementia care.

We evaluated the efficacy and safety of Souvenaid (a multinutrient supplement) in patients with mild Alzheimer's disease (AD) in real clinical practice and assessed a potential synergistic effect of acetylcholinesterase (AChE) inhibitors. Clinical Dementia Rating (CDR) scale was evaluated after six months follow-up. Patients were divided into 4 groups according to the treatment they received: Souvenaidâ+âAChE inhibitors (nâ=â23); only Souvenaid (nâ=â8); only AChE inhibitors (nâ=â7); no treatment (nâ=â16). The Souvenaidâ+âAChE inhibitors and Souvenaid alone groups were associated with significantly lower increases in CDR per month than the AChE inhibitors or no treatment ones. The efficacy of Souvenaidâ+âAChE inhibitors tended to be higher than Souvenaid alone.

In this study, new 1,2,3-triazole derivatives containing chalcone core (1-7) were synthesized. Obtained compounds were characterized by IR, 1H NMR, 13C NMR, and mass studies. Characterized compounds (1-7) inhibitory effects were tested against the glutathione S-transferase (GST), acetylcholinesterase (AChE), and Butyrylcholinesterase (BChE). Their Ki values were in the range of 5.88-11.13 µM on AChE, 5.08-15.12 µM on BChE, and 9.82-13.22 µM on GST. Remarkable inhibitory effects were obtained against three tested metabolic enzymes. Also, binding scores of the best-inhibitors against AChE, BChE, and GST enzymes were detected as -9.969 kcal/mol, -10.672 kcal/mol, and -8.832 kcal/mol, respectively. Isoindoline-1,3-dione and benzothiophene moieties played a critical role in the inhibition of AChE and BChE enzymes, respectively. Phenylene and triazole moieties had the most important interactions for inhibition of the GST enzyme. Therefore, in vivo and in silico results indicated that these compounds can be considered in drug design processes for the treatment of some diseases including Alzheimer's disease (AD), leukemia, and some type of cancer.

BACKGROUND: Four prescription drugs (donepezil, galantamine, memantine, and rivastigmine) are approved by the US FDA to treat symptoms of Alzheimer's disease (AD). Even modest effectiveness could potentially reduce the population-level burden of AD and related dementias (ADRD), especially for women and racial/ethnic minorities who have higher incidence of ADRD. OBJECTIVE: Describe the prevalence of antidementia drug use and timing of initiation relative to ADRD diagnosis among a nationally representative group of older Americans, and if there are disparities in prevalence and timing by sex and race/ethnicity. METHODS: Descriptive analyses and logistic regressions of Medicare claims (2008-2016) for beneficiaries who had an ADRD or dementia-related symptom diagnosis, or use of an FDA approved drug for AD. We investigate prevalence of use and timing of treatment initiation relative to ADRD diagnosis across time and beneficiary characteristics (age, sex, race/ethnicity, socioeconomic status, comorbidities). RESULTS: Among persons diagnosed with ADRD or related symptoms, 33.3% used an approved drug over the study period. Odds of use was higher among Whites than non-Whites. Among ADRD drug users, 40% initiated use within 6 months of the initial ADRD or related symptoms diagnosis, and 16% initiated prior to a diagnosis. We observed disparities by race/ethnicity: 28% of Asians, 24% of Hispanics, 16% of Blacks, and 15% of Whites initiated prior to diagnosis. CONCLUSIONS: The use of antidementia drugs is relatively low and varies widely by race/ethnicity. Heterogeneity in timing of initiation and use may affect health and cost outcomes, but these effects merit further study.

OBJECTIVES: The only recommended pharmacological treatments for specific dementias are donepezil, galantamine, rivastigmine, and memantine (recommended drugs, RD). However, other drugs without recommendations (not recommended drugs, NRD) are often used to treat patients with cognitive impairment (CI) in Argentina. The INSSJyP is the largest health insurance in Argentina. The objective of this study is to analyze the prescription pattern, cost, and implications of NRD used for the treatment of CI in the INSSJyP. MATERIALS: This is a retrospective, population-based study of the INSSJyP outpatients' prescriptions database for drugs usually prescribed for CI during 2015. These data were compared with the same database in 2009. The number of "prescriptions" always refers to dispensed packages. RESULTS: A total of 3 255 438 packages of drugs usually indicated for CI were prescribed during 2015: 1 912 476 packages of RD (59%) and 1 342 962 packages of NRD (41%).Comparing the results with those obtained in 2009, there is a 148% gross increase in the prescription of both RD and NRD for CI, although the rates/1000 affiliates/year show a lesser rise for NRD (70.1%) compared to RD (103.9 %).The expenditure on CI drugs prescribed during 2015 was 77 million USD. NRD cost represented approximately 20 million USD. CONCLUSION: Inappropriate drug use increases health costs in developing countries. We found a high number of patients with a probable diagnosis of CI treated with NRD. It is extremely relevant that all the healthcare professionals can update their knowledge and modify behavioral insights about appropriate prescription for specific dementias.

ââââEffective multifactorial management of Alzheimer's disease (AD) requires a triadic alliance of the clinician, the patient, and the patient's family and/or care partner(s). During the evaluation process and when the diagnosis of AD is delivered, these parties must work together to set goals and develop care plans. Care plans should be designed to help the patient maintain safety and autonomy as long as he or she can and, once autonomy is no longer possible, to allow the patient and care partner(s) to experience as much comfort and the best possible quality of life for as long as possible. In this Academic Highlights, faculty members from neurology, psychiatry, neuropsychology, and primary care share their recommendations, supported by current evidence and guidelines, for handling the complexities of providing care for patients with AD.

Introduction: The present status of amifampridine (AFP) for the treatment of Lambert-Eaton myasthenic syndrome (LEMS) is reviewed. Areas covered: All relevant literature identified through a PubMed search under treatment of LEMS, aminopyridine, and amifampridine are reviewed. An expert opinion on AFP was formulated. Expert opinion: AFPs, 3,4-DAP and 3,4-DAPP, are the most studied drugs in neuromuscular diseases. Randomized and non-randomized studies showed the most effective drug as symptomatic medication for LEMS. AFPs are safe and tolerable. Thus, AFPs should be the drug of choice for the symptomatic treatment in LEMS. As long as the daily dose is less than 80 mg a day, there is no concern for the serious side-reaction, seizure. Because of short-acting drug effects, it should be given three or four times a day. Peri-oral and finger paresthesia, the most common side-reaction, is accepted as a sign of drug-intake by many patients. Gastro-intestinal side reactions, the next common side-reaction of AFPs, are tolerable. AFPs are also the drug of choice and life-saving for LEMS crisis. For the long-term usage, it is proven to be safe and AFPs can be supplemented with liberal amount of pyridostigmine to sustain a symptomatic improvement without any undue side-reaction.

BACKGROUND: The cost-effectiveness of both cholinesterase inhibitors and memantine by delaying nursing home placement has been supported by numerous studies. The importance of sustained pharmacological treatment in dementia has been relatively less recognized by public health policies compared to early diagnosis. We investigated the effect of the drug (donepezil, rivastigmine, galantamine, and memantine) compliance on the health care costs in newly-diagnosed dementia. METHODS: National Health Insurance Service (NHIS) database which covers the entire population of South Korea was used for analysis. Health care expenditure of patients newly-diagnosed with dementia in between 2012 and 2014 was investigated for 3-5 years. For drug compliance, we used Medication Possession Ratio (MPR) that indicates the percentage of time a patient has access to medication. Multivariate linear regression analysis including generalized estimated equation and gamma distribution was used for statistical analysis. RESULTS: We identified 252,594 patients who were both prescribed with cognitive enhancers and newly diagnosed with dementia. When initial MPR increased 20%, total health care costs decreased 8.4% (RRâ¯=â¯0.916, 95%; CI 0.914 to 0.916). Same relationship was shown with medical costs related to dementia, admission to a general hospital, and emergency room visits. When MPR increased 20% compared to the previous year, the total health care costs, admission to a general hospital, emergency room visits, and admission to a nursing hospital decreased. CONCLUSIONS: This population-based retrospective cohort study provides evidence that patients newly-diagnosed with dementia who showed higher initial drug compliance or maintained antidementia drugs (Cholinesterase inhibitors and memantine) would benefit in total health-care costs.

AIM: Alzheimer's disease is a common cause of dementia, and is usually treated with medications that elevate acetylcholine levels. The objective of the present study was to identify drugs with anticholinergic properties prescribed to patients diagnosed with Alzheimer's disease in Colombia. METHODS: A cross-sectional study was carried out in outpatients diagnosed with Alzheimer's disease who were identified from a population database from Colombia, and had been treated with cholinesterase inhibitors and glutamate N-methyl-D-aspartate receptor antagonists. The anticholinergic burden was evaluated using the Anticholinergic Cognitive Burden scale, and patients were classified on a scale of 0-3 points according to anticholinergic potential, and were grouped into those with mild-to-moderate (1-2 points) or high (≥3 points) anticholinergic load. RESULTS: The study included 4134 Alzheimer's disease patients. The mean age was 81.50 ± 8.16 years, and 67.8% were women. At least 22.9% of patients took anticholinergic drugs. Of these, the most frequently prescribed medication was quetiapine (8.6%). Age >85 years was associated with a high risk of having an anticholinergic burden ≥3 points (OR 2.19, 95%CI 1.159-4.162). Potential interactions between cholinesterase inhibitors and anticholinergic drugs were identified in 7.8% of patients. CONCLUSIONS: The majority of patients who were prescribed anticholinergic drugs were older women, had a significant total anticholinergic burden and had frequent pharmacological interactions with cholinesterase inhibitors. The use of anticholinergics reduces the clinical effectiveness of antidementia drugs and increases the risk of adverse reactions. Geriatr Gerontol Int 2019; 19: 913-917.

Objective: To perform a cost-effectiveness analysis of donepezil and rivastigmine therapy for mild and moderate Alzheimer's disease (AD) from the perspective of the Brazilian Unified Health System. Method: A hypothetical cohort of 1,000 individuals of both sexes, aged >65 years, and diagnosed with AD was simulated using a Markov model. The time horizon was 10 years, with 1-year cycles. A deterministic and probabilistic sensitivity analysis was performed. Results: For mild AD, the study showed an increase in quality-adjusted life years (QALYs) of 0.61 QALY/21,907.38 Brazilian reais (BRL) for patients treated with donepezil and 0.58 QALY/BRL 24,683.33 for patients treated with rivastigmine. In the moderate AD group, QALY increases of 0.05/BRL 27,414.96 were observed for patients treated with donepezil and 0.06/BRL 34,222.96 for patients treated with rivastigmine. Conclusions: The findings of this study contradict the standard of care for mild and moderate AD in Brazil, which is based on rivastigmine. A pharmacological treatment option based on current Brazilian clinical practice guidelines for AD suggests that rivastigmine is less cost-effective (0.39 QALY/BRL 32,685.77) than donepezil. Probabilistic analysis indicates that donepezil is the most cost-effective treatment for mild and moderate AD.
