ABSTRACT

BACKGROUND: Sex-based disparities in cardiovascular outcomes may be improved with appropriate hypertension management. OBJECTIVE: To compare the evidence-based evaluation and management of females with late-onset hypertension compared to males in the contemporary era. METHODS: Design: Retrospective population-based cohort study. SETTING: Ontario, Canada. PARTICIPANTS: Residents aged ≥66 years with newly diagnosed hypertension between January 1, 2010, and December 31, 2017. EXPOSURE: Sex (female vs. male). OUTCOMES AND MEASURES: We used Poisson and logistic regression to estimate adjusted sex-attributable differences in the performance of guideline-recommended lab investigations. We estimated adjusted differences in time to the prescription of, and type of, first antihypertensive medication prescribed between females and males, using Cox regression. RESULTS: Among 111,410 adults (mean age 73 years, 53% female, median follow-up 6.8 years), females underwent a similar number of guideline-recommended investigations (adjusted incidence rate ratio, 0.997 [95% confidence interval [CI] 0.99-1.002]) compared to males. Females were also as likely to complete all investigations (0.70% females, 0.77% males; adjusted odds ratio, 0.96 [95% CI 0.83-1.11]). Females were slightly less likely to be prescribed medication (adjusted hazard ratio [aHR] 0.98 [95% CI 0.96-0.99]) or, among those prescribed, less likely to be prescribed first-line medication (aHR, 0.995 [95% CI 0.994-0.997]). CONCLUSIONS: Compared to males, females with late-onset hypertension were equally likely to complete initial investigations with comparable prescription rates. These findings suggest that there may be no clinically meaningful sex-based differences in the initial management of late-onset hypertension to explain sex-based disparities in cardiovascular outcomes.

ABSTRACT

BACKGROUND AND OBJECTIVES: Bullous pemphigoid (BP) clinical profile may have evolved during the last 2 decades. A retrospective, single-centre analysis investigated a possible shift of clinical presentation of the disease over time regarding both lesions' clinical pattern and locations and more particularly an increased frequency of characteristics considered as less classical regarding the usual clinical description of BP. PATIENTS AND METHODS: Initial clinical data from all BP patients treated between January 2001 and April 2017 in a reference centre were collected and compared between four 4-year successive chronological subsets (G1 to G4). RESULTS: 213/312 patients retained for final analysis (68.3%) displayed at least one initial non-classical characteristic, mainly head and neck, palmo-plantar, and/or mucosal involvement. Chronological analysis confirmed a significant increase over time of the percentage of patients displaying such features (G1 57.9% vs. G4 73.7%, p = 0.041). CONCLUSION: Changes in BP clinical pattern may have occurred over the last two decades with the progressive emergence of forms with a number of less classical features. No significant clinical difference was observed between patients receiving or not DPP4 inhibitors at the time of diagnosis.

ABSTRACT

OBJECTIVES: To describe new-onset IBD (new IBD) in patients treated with IL-17 inhibitors (IL-17i), to assess their incidence and to identify their risk factors in real life. METHODS: A French national registry (MISSIL) aimed to report all cases of new IBD in patients treated with IL-17i from January 2016 to December 2019. Using the estimated number of patients treated by IL-17 in France during the study period, the annual incidence rates of new IBD was reported in IL-17i-treated patients. A case-control study was performed with two controls per new IBD case matched by gender, age and underlying inflammatory disease. RESULTS: Thirty-one cases of new IBD under IL-17i were collected: 27 patients treated for spondyloarthritis and four patients for psoriasis. All were observed with secukinumab (SEK). The median time to onset of new IBD symptoms was 4.0 (1.5-7.5) months. SEK was discontinued in all patients. The evolution was favourable with complete resolution (17/31), improvement (7/31) or stabilization (5/31). Two patients died: one due to a massive myocardial infarction and one due to post-colectomy complications. The incidence of new IBD decreased from 0.69/100 patient-years [PY] (7/1010) in 2016 to 0.08/100 PY (6/7951) in 2019. No previous treatment with etanercept (odds ratio [OR] = 0.33, 95% CI: 0.14-0.80, P = 0.014) and low number of previous biologic therapies (OR = 0.67, 95% CI: 0.47, 0.94, P = 0.021) were significantly associated with new IBD. CONCLUSION: The incidence of new IBD was low and decreased from 2016 to 2019. The outcome was favourable in 24 out of 31 patients, but two patients died.

ABSTRACT

Combined therapies involve the use of multiple drugs to increase efficacy and reduce the toxicity of individual treatments. We evaluated the use of combinations of conventional systemic therapies and biologics in children with psoriasis in daily practice. This two-part study used data from the 170 children in the Franco-Italian BiPe cohorts to evaluate the use, efficacy, and safety of combined conventional systemic-biologic therapies, and from a survey carried out among French and Italian dermatologists to better understand the reasons for using or avoiding these combinations. In total, 33 children (19.4%) from 13 dermatology centers received 48 combined conventional systemic-biologic therapies (cumulative duration: 43.6 years), including three triple combination therapies (acitretin-methotrexate, with a TNF-alpha inhibitor). A total of 14 different combinations were used, most frequently etanercept-acitretin (n = 10), adalimumab-acitretin (n = 7), adalimumab-methotrexate (n = 5), and ustekinumab-methotrexate (n = 5). The combined therapies were started at biologic initiation in 41 cases (85.4%), and after a period of biologic monotherapy in the remaining 7 cases. Mean PGA and PASI scores decreased between baseline and M3 with all the combinations used. Four serious adverse events were reported, all with favorable outcomes. The survey was completed by 61 dermatologists: 39 (63.9%) had previously used or planned to use the combined therapies, most commonly TNF-alpha inhibitors with acitretin or methotrexate. The main reason for using these treatments was to improve the outcome of biologic therapies in cases of partial efficacy or loss of efficacy. Combined therapies have been used frequently in the treatment of childhood psoriasis, in a range of clinical situations and in variable drug combinations, without significant toxicity. Although the use of these combined therapies needs to be clarified in future management guidelines, these combined therapies should be considered for the treatment of children with severe psoriasis, psoriatic arthritis, and recalcitrant disease.

ABSTRACT

BACKGROUND: There is currently little information on switching biologics in pediatric psoriasis. OBJECTIVE: To evaluate the real-world clinical practice and safety of switching biologics in the "Biological Treatments for Pediatric Psoriasis" (BiPe) cohort. METHODS: Data for all 134 patients included in the BiPe cohort were analyzed. A further evaluation of the subpopulation of patients who switched from a first-line biologic to a second-line biologic was then conducted. Drug survival rates were also compared between biologics given as first-line or second-line agents. RESULTS: Overall, 29 patients (female: 55%; mean age: 16.6 ± 3.0 years) switched between two biologics. Etanercept (ETN) was the first-line biologic used in 23 patients: 16 (69.6%) switched to adalimumab (ADA) and seven (30.4%) to ustekinumab (UST). Six patients received first-line ADA and switched to UST. Loss of efficacy (62.1%), primary inefficacy (20.7%), and parental choice (6.9%) were the main reasons for switching biologics. One (3.4%) of the switches was performed because of adverse events or intolerance. For UST and ADA, the 18-month drug survival rate did not differ according to whether the agent was given as a first-line or second-line biologic (UST: P = .24; ADA: P = .68). No significant differences in drug survival rates were observed between the three different switches (ADA to UST, ETN to ADA, and ETN to UST). CONCLUSION: Our study provided key insights into the real-life clinical practice of switching biologics in pediatric psoriasis patients. However, more information and guidance on switching biologics in pediatric psoriasis are needed to improve real-life practice and outcomes.

ABSTRACT

Low-dose methotrexate is widely used in mycosis fungoides and Sézary syndrome, but few studies have evaluated this treatment. The aim of this study was to evaluate the benefit/risk ratio of this regimen on skin lesions. A retrospective survey of a series of patients treated for mycosis fungoides or Sézary syndrome with low-dose methotrexate and followed for at least one year in a tertiary referral centre was performed. From a total of 48 patients, complete response and partial response were achieved in 10 (21%) and 25 (52%) patients, respectively, with no significant difference in response rates between mycosis fungoides and Sézary syndrome. Of the responders, 20 out of 35 (57%) relapsed after a median time of 11 months. Forty-four of the total of 48 patients discontinued methotrexate, mainly due to primary or secondary failure and/or limiting toxicity (9 patients). Overall, the benefit/risk ratio of low-dose methotrexate in mycosis fungoides and Sézary syndrome appears favorable and this treat-ment remains a valid option in mycosis fungoides/Sézary syndrome. However, its activity is limited in duration and significant toxicity may occur in some patients.

ABSTRACT

Fungi constitute an abundant source of natural polysaccharides, some of them harboring original structures which can induce responses in mammalian or plant cells. An alkaline extract from the edible mushroom Pleurotus ostreatus has been obtained and called Pleuran complex cell wall extract (CCWE). It consists of a glucan-peptide complex whose components fall in a quite broad range of molecular weights, from 30 to 80 kDa. Pleuran extract has been tested on cultivated plants in laboratory conditions and also during field trial for its capacity to stimulate plant defenses in response to pathogen attack. Following Pleuran CCWE treatment, enhanced levels of various biochemical markers associated with plant responses have been observed, including enzymatic activities (e.g., peroxidase) or expression of some pathogenesis-related genes. In addition, during field experiments, we have noticed significant reductions in disease symptom levels in relation to different plant/pathogen systems (wheat/septoria, vine/mildew). These results confirmed that Pleuran CCWE could be used as an elicitor of plant defenses and could help in reducing pesticide applications against plant pathogens.

ABSTRACT

Alkaline treatment is a common step largely used in the industrial extraction of agar, a phycocolloid obtained from red algae such as Gelidium sesquipedale. The subsequent residue constitutes a poorly valorized by-product. The present study aimed to identify low-molecular-weight compounds in this alkaline waste. A fractionation process was designed in order to obtain the oligosaccharidic fraction from which several glycerol-galactosides were isolated. A combination of electrospray ion (ESI)-mass spectrometry, ¹H-NMR spectroscopy, and glycosidic linkage analyses by GC-MS allowed the identification of floridoside, corresponding to Gal-glycerol, along with oligogalactosides, i.e., (Gal)2⁻4-glycerol, among which α-d-galactopyranosyl-(1→3)-ß-d-galactopyranosylα1-2⁻glycerol and α-d-galactopyranosyl-(1→4)-ß-d-galactopyranosylα1-2⁻glycerol were described for the first time in red algae.

ABSTRACT

This article presents a new insight about TBY-2 cells; from extracellular polysaccharides secretion to cell wall composition during cell suspension culture. In the medium of cells taken 2 days after dilution (end of lag phase), a two unit pH decrease from 5.38 to 3.45 was observed and linked to a high uronic acid (UA) amount secretion (47.8%) while, in 4 and 7 day-old spent media, pH increased and UA amounts decreased 35.6 and 42.3% UA, respectively. To attain deeper knowledge of the putative link between extracellular polysaccharide excretion and cell wall composition, we determined cell wall UA and neutral sugar composition of cells from D2 to D12 cultures. While cell walls from D2 and D3 cells contained a large amount of uronic acid (twice as much as the other analysed cell walls), similar amounts of neutral sugar were detected in cells from lag to end of exponential phase cells suggesting an enriched pectin network in young cultures. Indeed, monosaccharide composition analysis leads to an estimated percentage of pectins of 56% for D3 cell wall against 45% D7 cell walls indicating that the cells at the mid-exponential growth phase re-organized their cell wall linked to a decrease in secreted UA that finally led to a stabilization of the spent medium pH to 5.4. In conclusion, TBY-2 cell suspension from lag to stationary phase showed cell wall remodeling that could be of interest in drug interaction and internalization study.

ABSTRACT

The aim of this 10-year monocentric prospective study was to determine a cut-off value of Fas/CD95 expression by peripheral blood CD4+ T lymphocytes in discriminating patients with mycosis fungoides from controls with cutaneous benign lymphocytic conditions. CD95 expression in peripheral blood CD4+ T lymphocytes was measured using flow cytometry in 330 patients referred for diagnosis: 104 with mycosis fungoides and 226 with eczema, psoriasis, drug reaction, etc. The sensitivity and specificity of different thresholds of CD95 expression were calculated regarding the final diagnosis of patients with mycosis fungoides or controls. CD95 expression higher than 30% reached a specificity of 91% in ruling out a diagnosis of mycosis fungoides, although overall CD95 expression was not significantly different from that of controls (p = 0.309) and sensitivity was very low (5%). Thus, peripheral CD95 expression higher than 30% could be used among the exclusion criteria in a multicomponent score for mycosis fungoides diagnosis.

ABSTRACT

BACKGROUND/AIMS: Previous reports highlighted the potential interest of cetuximab alone or in combination with chemotherapy in locally advanced or metastatic cutaneous squamous cell carcinomas (cSCC) care. MATERIAL AND METHODS: To further evaluate the efficiency and safety of cetuximab in advanced cSCC, a single-center retrospective study including all patients treated with cetuximab alone or combined with carboplatin for locally advanced or metastatic cSCC was conducted in a tertiary referral center. The primary end point was the overall response rate (ORR) after 2 cycles of treatment. Secondary end points were best overall disease control rate (DCR), overall survival (OS), best response duration, progression-free survival (PFS), and toxicity profile. RESULTS: Of the 14 enrolled patients, no complete response was obtained after 2 cycles of treatment, but 3 partial responses and 6 stable diseases were observed. ORR and DCR were 21.4 and 64.3%, respectively. Median OS and PFS were 9.25 and 2.65 months, respectively. Median PFS was longer with combined treatment compared with cetuximab monotherapy (9.03 vs. 3.55 months). The safety profile was acceptable with a trend toward a relationship between acne-like rash and longer response (median PFS 5.2 vs. 2.2 months). DISCUSSION/CONCLUSION: In all series including ours, disease control is usually rapidly obtained with cetuximab alone or combined with conventional chemotherapy, although with a minority of partial responses and no complete response. However, this control is of short duration in most cases. The safety profile is acceptable. A randomized phase III trial is warranted to better assess the benefit/risk ratio.

ABSTRACT

Treatment with ipilimumab, a monoclonal antibody that antagonizes cytotoxic T-lymphocyte antigen-4 (CTLA-4), results in improved survival of patients with stage IIIc-IV melanoma. However, there is a lack of data on the efficacy of ipilimumab in patients with brain metastases. To evaluate the efficacy of ipilimumab for the treatment of brain metastasis in melanoma, a multicentre, retrospective analysis of 38 patients with brain metastases in melanoma, treated with ipilimumab in the context of the French Expanded Access Program, was performed. Three patients had a 3 partial response, 5 stable disease, 15 disease progression and 15 patients died during the induction phase due to disease progression. Median overall survival was 101 days (range 54-154). The brain metastases control rate was 16% (6/38). Ipilimumab may be effective in a few patients with central nervous system metastasis. However, patients with brain metastases and a low life expectancy may not benefit sufficiently from treatment with ipilimumab.

ABSTRACT

Although current systemic therapies significantly improved the outcome of advanced melanoma, the prognosis of patient with central nervous system (CNS) metastases remains poor especially when clinically symptomatic. We aimed to investigate the efficiency of CNS targets and tolerance of second-line combined anti-PD1/dual-targeted anti-BRAF/anti-MEK therapy implemented in patients with CNS progression after initially efficient first-line combined targeted therapy in patients with BRAF-mutated melanoma in a real-life setting. A monocentric retrospective analysis including all such patients treated from January 2017 to January 2022 was conducted in our tertiary referral center. The response of CNS lesions to second-line triple therapy was assessed through monthly clinical and at least quarterly morphological (according to RECIST criteria) evaluation. Tolerance data were also collected. Seventeen patients were included with a mean follow-up of 2.59 (±2.43) months. Only 1 patient displayed a significant clinical and morphological response. No statistically significant difference was observed between patients receiving or not additional local therapy (mainly radiotherapy) as to response achievement. Immunotherapy was permanently discontinued in 1 patient owing to grade 4 toxicity. Mean PFS and OS after CNS progression were 2.59 and 4.12 months, respectively. In this real-life survey, the subsequent addition of anti-PD1 to combined targeted therapy in melanoma patients with upfront CNS metastases did not result in significant response of CNS targets in most BRAF mutated melanoma patients with secondary CNS progression after initially successful first-line combined targeted therapy.
