Prognostic mortality factors in advanced light chain cardiac amyloidosis: A prospective cohort study.

AIMS: Predicting mortality in severe AL cardiac amyloidosis is challenging due to elevated biomarker levels and limited thresholds for stratifying severe cardiac damage. METHODS AND RESULTS: This prospective, observational, cohort study included de novo, confirmed cardiac AL amyloidosis patients at the Henri Mondor National Reference Centre. The goal was to identify predictors of mortality to enhance prognostic stratification and improve informed decision-making regarding therapy. Over the 12-year study period, among the 233 patients included, 133 were NYHA III-IV and 179 Mayo 2004 III. The independent predictors for mortality identified were hsTnT, NT-proBNP, cardiac output, and conjugated bilirubin. A novel prognostic, conditional stratification, Mondor amyloidosis cardiac staging (MACS) was developed with biomarker cut-off values for Stage 1: hsTnT ≤ 107 ng/L and NT-proBNP ≤ 3867 ng/L (n = 77; 33%); for stage 2 NT-proBNP > 3867 ng/L (n = 72; 30%). For stage 3, if troponin >107 ng/L, regardless of NT-proBNP then CB 4 µmol/L, was added (n = 41; 17.5%) and stage 4: CB > 4 µmol/L (n = 43; 18.5%). The median overall survival was 8 months 95% CI [2-24]. At 1 year, 102 (44%) patients died and the Kaplan-Meier median survival with MACS Stage 1 was not reached, while stage 2 was 15.2 months (95% CI [11-18]) and stage 3, 6.6 months (95% CI [1-13]). Notably, among European stage II patients, 17.1%, n = 8 were MACS stage 3 and European stage IIIb 21.4% (n = 23) were MACS stage 4. Importantly, among European stage IIIb patients 42.2% (n = 29) were classified MACS stage 4 and 12.5% n = 9 were only MACS stage 2. CONCLUSIONS: The Mondor prognostic staging system, including conjugate bilirubin may significantly improve prognostic stratification for patients with severe cardiac amyloidosis.

Curative surgical treatment of common bile duct stones: Retrospective cohort study.

BACKGROUND: In the event of symptomatic common bile duct (CBD) stones with dilated CBD, one possible curative treatment option is stone extraction through choledocotomy associated with cholecystectomy. Endoscopic treatment is only reserved for residual stones at 6 weeks. The aim of this study was to evaluate the results from laparoscopic curative surgical treatment of CBD stones with dilated CBD. METHODS: This is a retrospective single-centered cohort study. All consecutive patients admitted for laparoscopic cholecystectomy with evidence of CBD stones with dilated CBD from January 2010 to December 2020 at our center were included. Success was defined by CBD clearance at 6 weeks. Need for additional procedures, such as endoscopic sphincterotomy, immediate, and end-of-procedure morbi-mortality as well as factors associated with procedure failure, were also studied. RESULTS: A total of 246 patients who received curative treatment were included in the study. The success rate for the curative treatment was 93.1% (229 patients). Immediate postoperative morbidity was 24.4% with a 5.3% reintervention rate. Immediate and 6-week postoperative mortality rates were zero and 0.4%, respectively. The mean length of stay was 11.3 days. Factors associated with procedure failure appeared to be the occurrence of an early postoperative complication and the need for readmission during the period between surgery and drain removal. CONCLUSION: This study indicates that laparoscopic curative surgical treatment for symptomatic CBD stones may be performed with acceptable results without routine need for additional procedures.

Postoperative ileus after digestive surgery: Network meta-analysis of pharmacological intervention.

AIMS: Several medicinal treatments for avoiding postoperative ileus (POI) after abdominal surgery have been evaluated in randomized controlled trials (RCTs). This network meta-analysis aimed to explore the relative effectiveness of these different treatments on ileus outcome measures. METHODS: A systematic literature review was performed to identify RCTs comparing treatments for POI following abdominal surgery. A Bayesian network meta-analysis was performed. Direct and indirect comparisons of all regimens were simultaneously compared using random-effects network meta-analysis. RESULTS: A total of 38 RCTs were included in this network meta-analysis reporting on 6371 patients. Our network meta-analysis shows that prokinetics significantly reduce the duration of first gas (mean difference [MD] = 16 h; credible interval -30, -3.1; surface under the cumulative ranking curve [SUCRA] 0.418), duration of first bowel movements (MD = 25 h; credible interval -39, -11; SUCRA 0.25) and duration of postoperative hospitalization (MD -1.9 h; credible interval -3.8, -0.040; SUCRA 0.34). Opioid antagonists are the only treatment that significantly improve the duration of food recovery (MD -19 h; credible interval -26, -14; SUCRA 0.163). CONCLUSION: Based on our meta-analysis, the 2 most consistent pharmacological treatments able to effectively reduce POI after abdominal surgery are prokinetics and opioid antagonists. The absence of clear superiority of 1 treatment over another highlights the limits of the pharmacological principles available.

Alteration of the maximal renal water excretion capacity with kidney function and age in human.

PURPOSE: The kidney's capability to concentrate and dilute urine is crucial to maintaining body fluid compartments and plasma osmolality. Advanced age and chronic kidney disease (CKD) result in decreased maximal urine concentration. Less is known regarding urine dilution ability. The primary purpose of this study was to determine the relationship between maximal renal water excretion and renal function, age, and gender in humans. METHODS: This monocentric retrospective study includes patients referred to the Department of Clinical Physiology in Toulouse University Hospital to measure the glomerular filtration rate (mGFR) between April 2013 and February 2018. mGFR was assessed using inulin renal clearance and required ample hydration. We quantified the effects of age, gender and mGFR have on water excretion ability, which was assessed by minimal urinary osmolality (minUosm) and maximal free water clearance (maxCH2O). RESULTS: 666 patients were included (mean age 51 ± 14 years, 53% female). Mean mGFR was 82 ± 25 mL/min/1.73m2. MinUosm after hydration was higher in patients with renal insufficiency while maxCH2O was markedly lower. Age was also, with a weaker effect, associated with decreased in water excretion, independently of mGFR. MaxCH2O clearance was similar in both genders, whereas minUosm was lower in women, possibly resulting from a lower osmotic load. DISCUSSION: This study shows a decrease in maximal urinary dilution capacity and free water clearance with CKD and age, without gender difference. These alterations are mild but must be considered when a significant water intake is required or in the case of hyponatremia.

Prognostication algorithm for non-cirrhotic non-B non-C hepatocellular carcinoma-a multicenter study under the aegis of the French Association of Hepato-Biliary Surgery and liver Transplantation.

Background: Liver resection and local ablation are the only curative treatment for non-cirrhotic hepatocellular carcinoma (HCC). Few data exist concerning the prognosis of patients resected for non-cirrhotic HCC. The objectives of this study were to determine the prognostic factors of recurrence-free survival (RFS) and overall survival (OS) and to develop a prognostication algorithm for non-cirrhotic HCC. Methods: French multicenter retrospective study including HCC patients with non-cirrhotic liver without underlying viral hepatitis: F0, F1 or F2 fibrosis. Results: A total of 467 patients were included in 11 centers from 2010 to 2018. Non-cirrhotic liver had a fibrosis score of F0 (n=237, 50.7%), F1 (n=127, 27.2%) or F2 (n=103, 22.1%). OS and RFS at 5 years were 59.2% and 34.5%, respectively. In multivariate analysis, microvascular invasion and HCC differentiation were prognostic factors of OS and RFS and the number and size were prognostic factors of RFS (P<0.005). Stratification based on RFS provided an algorithm based on size (P=0.013) and number (P<0.001): 2 HCC with the largest nodule ≤10 cm (n=271, Group 1); 2 HCC with a nodule >10 cm (n=176, Group 2); >2 HCC regardless of size (n=20, Group 3). The 5-year RFS rates were 52.7% (Group 1), 30.1% (Group 2) and 5% (Group 3). Conclusions: We developed a prognostication algorithm based on the number (≤ or >2) and size (≤ or >10 cm), which could be used as a treatment decision support concerning the need for perioperative therapy. In case of bifocal HCC, surgery should not be a contraindication.

Time to Relapse After Discontinuing Systemic Treatment for Psoriasis: A Systematic Review.

BACKGROUND: The decision of when to discontinue systemic treatment after achieving remission in psoriasis is an important question. In this systematic review, we sought to evaluate time to relapse after the discontinuation of systemic treatment in psoriasis patients. METHODS: Systematic searches of PubMed, Cochrane Library, and Embase databases were performed for randomized controlled studies reporting time to relapse after discontinuation of systemic drugs in psoriasis patients. In addition, pharmaceutical companies were contacted by the authors regarding missing data from the identified publications. In each publication, the time to psoriasis relapse and the timing of drug discontinuation were carefully assessed. The level of psoriasis control at the time of drug discontinuation and the definition used for psoriasis relapse were taken into account. RESULTS: Thirty articles published before April 2021 were included in the systematic review. Four articles focused on conventional systemic treatments with methotrexate and/or cyclosporine, nine focused on tumor necrosis factor (TNF) antagonists, eight focused on interleukin-17 (IL-17) antagonists, eight focused on IL-12/23 or IL-23 antagonists, and one focused on tofacitinib and apremilast. Different definitions were used to define psoriasis treatment success at the time of drug discontinuation. Similarly, heterogeneous criteria were used to define psoriasis relapse. Comparison between drugs was performed indirectly (i.e. across studies) for most drugs. Considering time of 50% loss of maximum Psoriasis Area Severity Index (PASI) improvement, a shorter median time to psoriasis relapse was observed with traditional systemic treatment (~ 4 weeks) compared to biological agents (from 12 to ~ 34 weeks). When using stringent relapse criteria, such as loss of PASI 90, a longer time to relapse after treatment cessation was observed with IL-23 antagonists (21-42 weeks) versus IL-17 antagonists (7-24 weeks). CONCLUSION: Biological agents are associated with a longer time to relapse than oral systemic agents after drug discontinuation. Among biologicals, IL-23 antagonists are associated with the longest time to relapse. These findings may have clinical consequences for the selection of systemic agents when intermittent treatment is necessary.

Dexamethasone is associated with early deaths in light chain amyloidosis patients with severe cardiac involvement.

BACKGROUND: Cardiac light chain amyloidosis (AL-CA) patients often die within three months of starting chemotherapy. Chemotherapy for non-immunoglobulin M gammopathy with AL-CA frequently includes bortezomib (Bor), cyclophosphamide (Cy), and dexamethasone (D). We previously reported that NT-ProBNP levels can double within 24h of dexamethasone administration, suggesting a deleterious impact on cardiac function. In this study, we evaluate the role of dexamethasone in early cardiovascular mortality during treatment. METHODS AND FINDINGS: We retrospectively assessed 100 de novo cardiac AL patients (62% male, mean age 68 years) treated at our institute between 2009 and 2018 following three chemotherapy regimens: CyBorDComb (all initiated on day 1; 34 patients), DCyBorSeq (D, day 1; Cy, day 8; Bor, day 15; 17 patients), and CyBorDSeq (Cy, day 1; Bor, day 8; D, day 15; 49 patients). The primary endpoint was cardiovascular mortality and cardiac transplantation at days 22 and 455. At day 22, mortality was 20.6% with CyBorDComb, 23.5% with DCyBorSeq, and 0% with CyBorDSeq (p = 0.003). At day 455, mortality was not significantly different between regimens (p = 0.195). Acute toxicity of dexamethasone was evaluated on myocardial function using a rat model of isolated perfused heart. Administration of dexamethasone induced a decrease in left ventricular myocardium contractility and relaxation (p<0.05), supporting a potential negative inotropic effect of dexamethasone in AL-CA patients with severe cardiac involvement. CONCLUSION: Delaying dexamethasone during the first chemotherapy cycle reduces the number of early deaths without extending survival. It is clear that dexamethasone is beneficial in the long-term treatment of patients with AL-CA. However, the initial introduction of dexamethasone during treatment is critical, but may be associated with early cardiac deaths in severe CA. Thus, it is important to consider the dosage and timing of dexamethasone introduction on a patient-severity basis. The impact of dexamethasone in the treatment of AL-CA needs further investigation.

Association between chronic idiopathic cough and sensitive skin syndromes is a new argument in favor of common neuropathic pathways: results from a survey on 4050 subjects.

Sensitive skin syndrome has a neuropathic origin, which is why it is frequently associated with irritable bowel syndrome. We have looked for a possible association with chronic cough, which is commonly maintained by neurogenic mechanisms, whatever the initial cause(s). A survey was carried out on a representative sample of the population over 15 years of age using the quota method. The questionnaire included sociodemographic data and questions about sensitive skin, the presence of chronic cough, smoking and possible causes of chronic cough. Chronic cough was assessed by the Leicester Cough Questionnaire, and 4050 subjects responded (mean age: 45 years). Overall, 12.2% of subjects with a chronic cough were compared to the 87.8% without any cough. Among them, 72.5% had sensitive skin (vs. 47.8%, p < 0.001); additionally, 17.4% of the subjects with sensitive skin had a chronic cough (vs. 6.9% if no sensitive skin). These proportions were higher if very sensitive skin was reported. The risk of having chronic cough was twice as high if sensitive skin was reported [OR = 1.9 (1.5-2.4), p < 0.001]. The risk of having sensitive skin was also twice as high for chronic cough. Thus, chronic cough and sensitive skin are frequently associated. This association represents a new argument in favor of a neuropathic nature of sensitive skin. Sensitive skin and chronic cough are both modes of overreaction to environmental factors, which tend to be autonomized by neurogenic mechanisms. Dermatologists should ask their patients if they have a chronic cough, and pneumologists should ask about the presence of sensitive skin.

Suppurative keloids: a complication of severe keloid disease.

BACKGROUND: Some keloids show cystic cavities that give rise to acute inflammatory flares and oozing. These suppurative keloids (SK) have rarely been systematically studied. We conducted a retrospective cohort study to evaluate SK frequency and its risk factors. We also reviewed microbiological analyses as well as the histological features of removed SKs. METHODS: Between July 1, 2015, and September 30, 2016, all adult patients attending a specialized keloid clinic were asked to participate. Clinical information and microbiological results were extracted from each patient's file. Histological features were observed and interpreted. RESULTS: In this study, we observed an SK rate of 26% for a mean keloid history of 17.2 years. Male gender, African ancestry, and a family history of keloids were significantly associated with suppuration. Microbiological examination revealed commensal skin flora 7/9 (77.8%), Staphylococcus aureus 1/9 (11.1%), and Enterococcus faecalis 1/9 (11.1%). CONCLUSION: Suppuration is a common complication of keloids occurring in patients with severe keloid disease and may arise from pilosebaceous occlusion and aseptic inflammation.

Good performance in the management of acute heart failure in cardiogeriatric departments: the ICREX-94 experience.

CONTEXT: A growing number of elderly patients hospitalized for Acute Heart Failure (AHF) are being managed in cardiogeriatrics departments, but their characteristics and prognosis are poorly known. This study aimed to investigate the profile and outcome (rehospitalization at 90 days) of patients hospitalized for AHF in cardiogeriatrics departments in the Val-de-Marne area in the suburbs of Paris, and to compare them to AHF patients hospitalized in cardiology departments in the same area. METHODS: Observational study, ICREX-94, conducted in seven cardiology departments in France and three specific cardiogeriatrics departments in Val-de-Marne. RESULTS: A total of 308 patients were hospitalized for AHF between October 2017 and January 2019. During the 90 days following discharge, 29.6% patients were readmitted to the hospital. Compared with patients hospitalized in cardiology departments, patients in cardiogeriatrics departments were older (p < 0.001), less independent (living more often alone or in an institution) (p < 0.001), more often depressed (p < 0.001), had more often major neurocognitive disorder (p < 0.001), had a higher Human Development Index (HDI, p < 0.001), and were less often diagnosed with amyloidosis (p < 0.001). There was no difference in outcome whether patients were discharged from cardiology or cardiogeriatrics departments. The most frequent precipitating factors underlying AHF decompensation between the first and second hospitalization were arrhythmia and infection. CONCLUSION: AHF patients discharged from cardiogeriatrics departments, compared to cardiology departments, showed clinical differences but had the same prognosis regarding AHF rehospitalization at 90 days.

Choice of Systemic Drugs for the Management of Moderate-to-severe Psoriasis: A Cross-country Comparison Based on National Health Insurance Data.

Current management of moderate-to-severe psoriasis may be heterogeneous between European countries, probably due to differences in the organization of care. The aim of this study was to compare the utilization of systemic treatments for psoriasis between 2 coun-tries. All adults with psoriasis who were registered in the French (SNDS) and the Dutch (VEKTIS) national health insurance databases between 2012 and 2016 were eligible for inclusion. In France, 105,035 (15%) of 684,156 patients and, in the Netherlands, 37,405 (28.6%) of 130,822 patients received at least a systemic agent. In France, the proportion of patients treated with systemic agents was constant, while the type of drugs dispensed shifted from non-biological to biological agents. In the Netherlands, the first systemic treatment was methotrexate and, in France, acitretin. In France, the choice of the first biologic was much more variable than it was in the Netherlands, where a large proportion of patients were dispensed ustekinumab. This study highlights discrepancies between France and the Netherlands concerning the choice of first non-biologic agent and first biologic agent for patients with psoriasis. These discrepancies may be due to differences in the healthcare systems between the 2 countries.

Surgical Interventions for Patients With Vitiligo: A Systematic Review and Meta-analysis.

Importance: Surgical interventions are a key part of the therapeutic arsenal, especially in refractory and stable vitiligo. Comparison of treatment outcomes between the different surgical procedures and their respective adverse effects has not been adequately studied. Objective: To investigate the reported treatment response following different surgical modalities in patients with vitiligo. Data Sources: A comprehensive search of the MEDLINE, Embase, Web of Science, and Cochrane Library databases from the date of database inception to April 18, 2020, was conducted. The key search terms used were vitiligo, surgery, autologous, transplantation, punch, suction blister, and graft. Study Selection: Of 1365 studies initially identified, the full texts of 358 articles were assessed for eligibility. A total of 117 studies were identified in which punch grafting (n = 19), thin skin grafting (n = 10), suction blister grafting (n = 29), noncultured epidermal cell suspension (n = 45), follicular cell suspension (n = 9), and cultured epidermal cell suspension (n = 17) were used. Data Extraction and Synthesis: Three reviewers independently extracted data on study design, patients, intervention characteristics, and outcomes. Random effects meta-analyses using generic inverse-variance weighting were performed. Main Outcomes and Measures: The primary outcomes were the rates of greater than 90%, 75%, and 50% repigmentation response. These rates were calculated by dividing the number of participants in an individual study who showed the corresponding repigmentation by the total number of participants who completed the study. The secondary outcomes were the factors associated with treatment response to the surgical intervention. Results: Among the 117 unique studies and 8776 unique patients included in the analysis, rate of repigmentation of greater than 90% for surgical interventions was 52.69% (95% CI, 46.87%-58.50%) and 45.76% (95% CI, 30.67%-60.85%) for punch grafting, 72.08% (95% CI, 54.26%-89.89%) for thin skin grafting, 61.68% (95% CI, 47.44%-75.92%) for suction blister grafting, 47.51% (95% CI, 37.00%-58.03%) for noncultured epidermal cell suspension, 36.24% (95% CI, 18.92%-53.57%) for noncultured follicular cell suspension, and 56.82% (95% CI, 48.93%-64.71%) for cultured epidermal cell suspension. The rate of repigmentation of greater than 50% after any surgical intervention was 81.01% (95% CI, 78.18%-83.84%). In meta-regression analyses, the treatment response was associated with patient age (estimated slope, -1.1418), subtype of vitiligo (estimated slope, 0.3047), and anatomical sites (estimated slope, -0.4050). Conclusions and Relevance: The findings of this systematic review and meta-analysis suggest that surgical intervention can be an effective option for refractory stable vitiligo. An appropriate procedure should be recommended based on patient age, site and size of the lesion, and costs.

Perineal Wound Closure Following Abdominoperineal Resection and Pelvic Exenteration for Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Abdominoperineal resection (APR) and pelvic exenteration (PE) for the treatment of cancer require extensive pelvic resection with a high rate of postoperative complications. The objective of this work was to systematically review and meta-analyze the effects of vertical rectus abdominis myocutaneous flap (VRAMf) and mesh closure on perineal morbidity following APR and PE (mainly for anal and rectal cancers). METHODS: We searched PubMed, Cochrane, and EMBASE for eligible studies as of the year 2000. After data extraction, a meta-analysis was performed to compare perineal wound morbidity. The studies were distributed as follows: Group A comparing primary closure (PC) and VRAMf, Group B comparing PC and mesh closure, and Group C comparing PC and VRAMf in PE. RESULTS: Our systematic review yielded 18 eligible studies involving 2180 patients (1206 primary closures, 647 flap closures, 327 mesh closures). The meta-analysis of Groups A and B showed PC to be associated with an increase in the rate of total (Group A: OR 0.55, 95% CI 0.43-0.71; p < 0.01/Group B: OR 0.54, CI 0.17-1.68; p = 0.18) and major perineal wound complications (Group A: OR 0.49, 95% CI 0.35-0.68; p < 0.001/Group B: OR 0.38, 95% CI 0.12-1.17; p < 0.01). PC was associated with a decrease in total (OR 2.46, 95% CI 1.39-4.35; p < 0.01) and major (OR 1.67, 95% CI 0.90-3.08; p = 0.1) perineal complications in Group C. CONCLUSION: Our results confirm the contribution of the VRAMf in reducing major complications in APR. Similarly, biological prostheses offer an interesting alternative in pelvic reconstruction. For PE, an adapted reconstruction must be proposed with specialized expertise.
