Psori Silk in Mild to Moderate Psoriasis: A Randomized Phase I-II Trial Study

In patients with mild to moderate psoriasis, topical corticosteroids are usually the first-line of treatment; however, they are not suitable for long-term use. The purpose of this study was to assess the efficacy and safety of a multi-fruit-and-vegetable compound, Psori Silk, in the treatment of patients with psoriasis. This was a randomized double-blind trial comprising 12 weeks of treatment with Psori Silk versus a vehicle, and a 4-week follow-up. The primary endpoint was 50% reduction in the modified Psoriasis Area and Severity Index (MPASI 50) score at week 12, while the secondary endpoint was quality of life assessment using the Dermatology Life Quality Index (DLQI). The Psori Silk group consisted of 23 patients with 34 lesions to be treated versus 22 patients in the vehicle group with 36 lesions. The MPASI 50 score was observed in 59% patients in the active group versus 22.7% patients in the vehicle group (P < 0.001). A mean 33% DLQI improvement was observed in 65.2% patients in the active group versus 27.2% patients in the vehicle group (P < 0.001). Mild and temporary discomfort at the site of application was reported in 39% patients in the active group versus 23% patients in the vehicle group. Psori silk appears to be an effective and safe treatment option for mild to moderate plaque psoriasis.

Psoriasis and Dementia: A Cross-sectional Study of 121,801 Patients

Data regarding the association between psoriasis and dementia are inconclusive. The aim of this study was to evaluate this association in the database of Clalit Health Services, Israel. A comparative analysis for the association between psoriasis, dementia and its risk factors was performed for the entire study population and in the subgroup of patients with moderate-to-severe psoriasis. The study included 121,801 patients with psoriasis, of whom 16,947 were diagnosed with moderate-to-severe psoriasis, and 121,802 controls. Psoriasis was associated with a lower prevalence of dementia relative to control subjects (1.6% vs 1.8%; odds ratio (OR) 0.85; 95% confidence interval (95% CI) 0.80–0.91; p < 0.001). Multivariate analysis adjusting for demographic variables, cardiovascular-related risk factors, and healthcare utilization demonstrated a significant inverse association between psoriasis and dementia in the entire study population (adjusted OR 0.86; 95% CI 0.76–0.96; p = 0.009), but not in the subgroup of patients with moderate-to-severe psoriasis (adjusted OR 0.91; 95% CI 0.81–1.02; p = 0.113). In conclusion, these data support the hypothesis that psoriasis is inversely associated with dementia.

Continuous terbinafine and pulse itraconazole for the treatment of non-dermatophyte mold toenail onychomycosis

INTRODUCTION

Although dermatophytes are considered the predominant causative organisms in onychomycosis, non-dermatophyte mold (NDM) infections may be more prevalent than originally thought and may be more difficult to treat. There are limited data of oral antifungal efficacy in treating NDM onychomycosis.

METHOD

A retrospective chart review (2009-2016) was conducted in patients receiving continuous oral terbinafine or pulse itraconazole for toenail onychomycosis due to NDMs. Mycology results and percent nail affected were recorded with patient characteristics including demographics and concurrent diseases. Complete, clinical, and mycological cure were tabulated.

RESULTS

Data from 176 patients were collected. Mycological and complete cure rates for terbinafine (69.8% and 17%) and itraconazole (67.5% and 22%) were not significantly different from each other. Regardless of oral treatment, age (p = .013), baseline severity (p = .016), and presence of atherosclerosis (p = .040) or hyperlipidemia (p = .033) decreased the likelihood of mycological cure, while age decreased the likelihood of complete cure (p = .001).

CONCLUSION

Continuous terbinafine and pulse itraconazole were similar in efficacy for curing NDM onychomycosis. Age was the most consistent prognostic factor affecting likelihood of cure, with factors that may influence drug reaching the site of infection also decreasing likelihood of mycological cure.

Healthcare Service Utilization by 116,816 Patients with Atopic Dermatitis in Israel

Understanding of the epidemiology and healthcare service utilization related to atopic dermatitis is necessary to inform the use of new treatments. This cross-sectional study was based on a group of patients with atopic dermatitis and a matched control group comprised of age- and sex- matched enrolees without atopic dermatitis from a large medical database. Healthcare service utilization usage data were extracted and compared between groups. The study included 116,816 patients with atopic dermatitis and 116,812 controls. Atopic dermatitis was associated with an increased burden of healthcare utilization across the entire spectrum of healthcare services compared with controls. For patients severely affected by atopic dermatitis, the increased burden correlated with disease severity: a high-er frequency of emergency room visits (odd ratio (OR) 1.7; 95% confidence interval (CI) 1.6-1.9), dermatology wards hospitalizations (OR 315; 95% CI 0-7,342), and overall hospitalizations (OR 3.6; 95% CI 3.3-3.9). In conclusion, this study demonstrates an increased burden of healthcare utilization in atopic dermatitis.

Chronic urticaria and osteoporosis: a longitudinal, community-based cohort study of 11 944 patients

BACKGROUND

Chronic urticaria (CU) carries many risk factors for osteoporosis, but data on the relationships between CU and osteoporosis are lacking.

OBJECTIVES

To evaluate the association between CU and osteoporosis in a large community-based study.

METHODS

A nationwide observational longitudinal cohort study was conducted. CU was defined as four pairs of urticaria diagnoses; each pair was recorded within a period of 6 weeks and was registered by physicians in a primary-care setting. Patients with CU and their age- and sex- matched controls were followed for the incidence of osteoporosis and other laboratory data between 2002 and 2017. Data regarding systemic steroid exposure and other relevant risk factors for osteoporosis were obtained. Analyses of risk for osteoporosis were performed in Cox regression models adjusted for age, sex, exposure to systemic corticosteroids, obesity, smoking and hyper- and hypothyroid disease.

RESULTS

The study included 11 944 patients with CU and 59 829 controls. During the study's observation period, 1035 (8·7%) patients with CU were diagnosed with osteoporosis, compared with 4046 (6·8%) controls. The adjusted multivariate analysis demonstrated that CU was significantly associated with a higher risk for osteoporosis (hazard ratio 1·23, 95% confidence interval 1·10-1·37, P < 0·001).

CONCLUSIONS

CU may impose a risk for osteoporosis. Appropriate targeted screening should be considered.

Global perspectives for the management of onychomycosis

Onychomycosis is a fungal nail infection caused by dermatophytes, nondermatophyte molds, and yeasts. This difficult-to-treat chronic infection has a tendency to relapse despite treatment. This paper aims to offer a global perspective on onychomycosis management from expert physicians from around the world. Overall, the majority of experts surveyed used systemic, topical, and combination treatments approved in their countries and monitored patients based on the product insert or government recommendations. Although the basics of treating onychomycosis were similar between countries, slight differences in onychomycosis management between countries were found. These differences were mainly due to different approaches to adjunctive therapy, rating the severity of disease and use of prophylaxis treatment. A global perspective on the treatment of onychomycosis provides a framework of success for the committed clinician with appreciation of how onychomycosis is managed worldwide.

Psoriasis in Israel: demographic, epidemiology, and healthcare services utilization

BACKGROUND

Updated data regarding the epidemiology of psoriasis and related healthcare utilization are lacking.

OBJECTIVE

To investigate the epidemiology, comorbidities, healthcare services utilization, and drug use in a large group of patients with psoriasis from Clalit Health Services (CHS) database.

METHODS

A controlled cross-sectional study was performed. Case patients were defined when there was at least one documented diagnosis of psoriasis registered by a CHS dermatologist between the years 1998-2016. The extracted data included metabolic, cardiovascular and psychiatric comorbidities; community clinic visits; in- and outpatient services utilization profiles and drug use data, which included pharmacy claims of topical and systemic treatments, including phototherapy and climatotherapy. Comparative analysis was performed by a univariate and multivariate analysis, adjusting for age, gender, obesity, and smoking.

RESULTS

The study included 118,680 patients with psoriasis (prevalence of 2.69%) and 118,680 age- and gender-matched controls. Patients with psoriasis had increased prevalence of metabolic, cardiovascular, and psychiatric illnesses. Psoriasis was significantly associated with an increased healthcare utilization. The mean (SD) number of annual dermatologist clinic visits and emergency room visits was 7.2 ± 12.4 and 2.9 ± 7.7 in psoriasis patients as compared to 2.9 ± 7.9 and 2.7 ± 7.4 in the control group (P < 0.001). Topical steroids were the most applied treatment in psoriasis patients (15.5%), and topical vitamin D analogs were second in use (14.6%). Traditional systemic treatment for psoriasis was used in 3.8% of the patients, and biologic treatments were used in 1.6% of the patients.

CONCLUSIONS

Our study quantifies healthcare services utilization and drug use in patients with psoriasis.

A Retrospective Study Comparing K101 Nail Solution as a Monotherapy and in Combination with Oral Terbinafine or Itraconazole for the Treatment of Toenail Onychomycosis

Background

Onychomycosis is a difficult-to-treat fungal infection of the nails. The efficacy of monotherapy is not ideal, and combination therapies provide an alternative that may increase treatment efficacy.

Method

A retrospective analysis of data from 91 patients was undertaken. Treatment for toenail onychomycosis occurred between 2014 and 2016 and consisted of combination therapy with oral terbinafine (250 mg/day for 12 weeks) or itraconazole (3 pulses, 400 mg/day for 7 days) + K101 nail solution daily, or K101 nail solution monotherapy. Efficacy outcomes at 12 and 15 months were analyzed.

Results

At 12 months, the clinical cure rate for combination of terbinafine + K101 solution was significantly higher than that for K101 monotherapy (p = 0.008). Patients receiving this combination also showed significant improvement in percent of affected nail at 3 months (p = 0.029), while patients receiving itraconazole + K101 solution demonstrated improvement in percent of affected nail at 6 months (p = 0.037). At 15 months, there was no significant difference between treatments for complete, clinical, and mycological cure.

Conclusion

Combination therapy with oral terbinafine or itraconazole and K101 nail solution results in clearance of infected nail earlier than that with topical K101 alone. These combinations may encourage compliance and be effective for patients with moderate onychomycosis.

Variability in Systemic Treatment Efficacy for Onychomycosis: Information That Clinical Studies Do Not Impart to the Office Dermatologist

Wide differences in the cure rates of onychomycosis in various clinical studies can be avoided if we bear in mind some insights that will help us make study results more consistent. We suggest less rigid criteria in defining the cure rate, the inclusion of all toenails in studies, and the exclusion of nails with a history of trauma. Rather than address patients as a homogenous group, regardless of age, we suggest dividing them into age groups. Researchers should not forget inflammatory diseases that can imply changes on the nails and should take into account the duration of onychomycosis, nail changes caused by asymmetry, and the possibility of dermatophytoma.

Demographic and health care service utilization by 4417 patients with hidradenitis suppurativa

BACKGROUND

Data on the health care utilization of patients with hidradenitis suppurativa (HS) in primary care settings are scarce.

OBJECTIVE

To investigate the health care service utilization of patients with HS.

METHODS

In a cross-sectional study, patients with HS were compared with 2 age- and sex-matched control groups-general population enrollees of Clalit Health Services and a group of patients with psoriasis. Health care services data included inpatient and outpatient community clinic visits and pharmacy claims for topical and systemic treatments. Multivariate analysis of the data for patients with HS and controls was performed.

RESULTS

The study included 4417 patients with HS, 22,085 general population enrollees, and 4417 patients with psoriasis. On the basis of multivariate analyses, patients with HS had more annual dermatology clinic visits compared with the general population enrollees (odds ratio [OR], 6.49; 95% confidence interval [CI], 7.06-5.97) and patients with psoriasis (OR, 1.32; 95% CI, 1.44-1.21), more annual surgical clinic visits (OR, 3.78; 95% CI 3.28-4.36 and OR, 1.65; 95% CI, 1.42-1.91, respectively), and more hospitalizations (OR, 2.21; 95% CI, 1.89-2.56 and OR, 1.51; 95% CI, 1.28-1.78, respectively).

LIMITATIONS

Underestimation of HS frequency was possible.

CONCLUSIONS

The burden on health care systems due to patients with HS is greater than that due to patients with psoriasis and the general population.

Monitoring of cardiac function in patients with a left ventricle assist device

In complex therapy of acute or chronic cardiac failure, the use of valve-free centrifugal pumps or artificial heart ventricles takes place. In these cases, simultaneous monitoring of cardiac and pump performance is very important. In this study, an ultrasound dilution method based on the registration of two dilution curves after intravenous injection of isotonic and hypertonic sodium solution was developed. Comparison of total cardiac output (TCO), which included pump and heart output measured by thermodilution and ultrasound (TCOus) dilution, yielded TCOus = 1.11TCOth - 0.54 (n = 13).

[Isolation and purification of two lipolytic enzymes from Vespa orientalis venom]

Two lipolytic enzymes--phospholipase A2 and lysophospholipase A1 were isolated in individual state from the venom of the big hornet Vespa orientalis. It was shown that these enzymes have approximately the same molecular weight of about 26 000, but differ in their electrophoretic mobilities. Besides, the enzymes possess marked specificity to lecithin and L-lysolecithin, respectively.
