Differences in the treatment needs of patients with dementia with Lewy bodies and their caregivers and differences in their physicians' awareness of those treatment needs according to the clinical department visited by the patients: a subanalysis of an observational survey study

BACKGROUND

We investigated whether the treatment needs of patients with dementia with Lewy bodies (DLB) and their caregivers, along with their attending physicians' perception of those treatment needs, differ according to the clinical department visited by the patients.

METHODS

This was a subanalysis of a multicenter, cross-sectional, observational survey study. Data from the main study were classified according to the clinical department visited by the patient: psychiatric group (P-group), geriatric internal medicine group (G-group), and neurology group (N-group). The treatment needs of patients and caregivers were defined as "the symptom that causes them the most distress", and the frequency of each answer was tabulated.

RESULTS

This subanalysis included 134, 65, and 49 patient-caregiver pairs in the P-, G-, and N-groups, respectively. Statistically significant differences in patient background characteristics such as patient age; initial symptom domains; use of cholinesterase inhibitors, levodopa, antipsychotics, and Yokukansan; and total scores of the Mini-Mental State Examination, Neuropsychiatric Inventory-12, and Movement Disorder Society-Unified Parkinson's Disease Rating Scale Parts II and III were shown among the three subgroups. While there were no differences in patients' treatment needs among the subgroups, residual analysis showed that in the N-group, parkinsonism was more of a problem than other symptom domains (p = 0.001). There were significant differences in caregivers' treatment needs among the three subgroups (p < 0.001). The patient-physician concordance rates for the symptom domains that caused patients the most distress were: P-group, 42.9% (kappa coefficient [κ] = 0.264); G-group, 33.3% (κ = 0.135), and N-group, 67.6% (κ = 0.484). The caregiver-physician concordance rates for the symptom domains that caused the caregivers the most distress were: P-group, 54.8% (κ = 0.351), G-group, 50.0% (κ = 0.244), and N-group, 47.4% (κ = 0.170).

CONCLUSION

This subanalysis revealed differences in the treatment needs of patients with DLB and their caregivers according to the clinical department they attended. There might be a lack of awareness of those treatment needs by the attending physicians, regardless of their specialty.

Factors associated with heart failure hospitalization in patients with high sodium excretion: subanalysis of the ESPRIT, evaluation of sodium intake for the prediction of cardiovascular events in Japanese high-risk patients, cohort study

We have reported that high sodium excretion ≥ 4.0 g/day, assessed by repeated measurements of spot urine, is associated with composite cardiovascular (CV) events of heart failure (HF) hospitalization, acute coronary syndrome, cerebrovascular events, and documented CV deaths in Japanese high-risk patients with either stable and compensated congestive HF, high brain natriuretic peptide, coronary artery disease, cerebrovascular disease, chronic kidney disease, or atrial fibrillation. A total of 520 patients were enrolled. During the median follow-up period of 5.2 years, 105 (20%) experienced composite CV events, which were predominantly driven by 60 (12%) HF hospitalizations. The aim of the present study was to elucidate which subgroups of patients with high sodium excretion were associated with HF hospitalization. We divided the enrolled patients into three groups according to the amount of sodium excretion (< 3.0 g/day, 3.0-3.99 g/day (reference), and ≥ 4.0 g/day) based on a median of 14 measurements during follow-up. We assessed the hazard ratio for HF hospitalization according to age, bodyweight, and gender, using the Cox hazard model. In the total population, high sodium excretion ≥ 4.0 g/day was associated with HF hospitalization [hazard ratio (HR) 1.75, confidence interval (CI) 1.05-2.83] after adjustment for gender, age, and bodyweight, but was not associated with other CV events. In older patients (≥ 75 years old), high sodium excretion ≥ 4.0 g/day was associated with HF hospitalization after adjustment for gender and bodyweight (HR 3.25, CI 1.55-6.55), which was not observed in younger (< 75 years old) patients. In patients with lower bodyweight (< 60 kg), high sodium excretion ≥ 4.0 g/day was associated with HF hospitalization after adjustment for age and gender (HR 3.05, CI 1.34-6.61), which was not observed in heavier (≥ 60 kg) patients. High sodium excretion is associated with HF hospitalization in patients with older age and lower bodyweight in Japanese high-risk patients.

Superior Efficacy with Ivermectin 1% Cream Compared to Metronidazole 0.75% Cream Contributes to a Better Quality of Life in Patients with Severe Papulopustular Rosacea: A Subanalysis of the Randomized, Investigator-Blinded ATTRACT Study

Introduction

Ivermectin 1% cream (IVM 1%) is indicated for the treatment of inflammatory lesions of rosacea. The objective of this subanalysis was to compare IVM 1% vs. metronidazole 0.75% cream (MTZ 0.75%) in the treatment of severe inflammatory lesions of rosacea.

Methods

A subanalysis of the investigator-assessed severe subjects from a Phase 3, investigator-blinded, randomized study comparing IVM 1% once daily (QD) with MTZ 0.75% twice daily (BID) over 16 weeks followed by a 36-week extension period was performed. Efficacy assessments were Dermatology Life Quality Index (DLQI) and EuroQol-5 Dimension (EQ-5D) questionnaires, investigator’s global assessment (IGA), subject assessment of rosacea improvement, and inflammatory lesion counts. Adverse events (AEs) were monitored throughout the study.

Results

A total of 161 subjects (16.7% of overall study population; 80 IVM 1% and 81 MTZ 0.75%) had an IGA score of 4 at baseline representing severe papulopustular rosacea. Significantly more IVM 1% subjects had a minimal clinically important difference (MCID, defined as a decrease from baseline of ≥4 points) in DLQI score than MTZ 0.75% subjects at week 16 (65.4% vs. 39.2%; P = 0.001) and week 52 (68.8% vs. 40.4%; P = 0.003). At week 16, the mean EQ-5D score for the IVM 1% subjects was higher (better quality of life) than for MTZ 0.75% subjects (0.941 vs. 0.896). Significantly more IVM 1% subjects were IGA “clear” or “almost clear” at week 16 compared to MTZ 0.75% (82.5% vs. 63.0%; P = 0.005). Incidence of AEs was comparable between groups.

Conclusion

Better efficacy with IVM 1% cream (QD) compared to MTZ 0.75% cream (BID) contributes to an improved quality of life with significantly more patients achieving an MCID in DLQI score at week 16 and higher mean EQ-5D score. IVM 1% cream is thus a better alternative than MTZ 0.75% cream for severe papulopustular rosacea patients.
