RESUMO

BACKGROUND: Both hereditary haemorrhagic telangiectasia (HHT) and juvenile polyposis syndrome (JPS) are known to be caused by SMAD4 pathogenic variants, with overlapping symptoms for both disorders in some patients. Additional connective tissue disorders have also been reported. Here, we describe carriers of SMAD4 variants followed in an HHT reference centre to further delineate the phenotype. METHODS: Observational study based on data collected from the Clinical Investigation for the Rendu-Osler Cohort database. RESULTS: Thirty-three participants from 15 families, out of 1114 patients with HHT, had an SMAD4 variant (3%).Regarding HHT, 26 out of 33 participants (88%) had a definite clinical diagnosis based on Curaçao criteria. Complication frequencies were as follows: epistaxis (n=27/33, 82%), cutaneous telangiectases (n=19/33, 58%), pulmonary arteriovenous malformations (n=17/32, 53%), hepatic arteriovenous malformations (AVMs) (n=7/18, 39%), digestive angiodysplasia (n=13/22, 59%). No cerebral AVMs were diagnosed.Regarding juvenile polyposis, 25 out of 31 participants (81%) met the criteria defined by Jass et al for juvenile polyposis syndrome. Seven patients (21%) had a prophylactic gastrectomy due to an extensive gastric polyposis incompatible with endoscopic follow-up, and four patients (13%) developed a digestive cancer.Regarding connective tissue disorders, 20 (61%) had at least one symptom, and 4 (15%) participants who underwent echocardiography had an aortic dilation. CONCLUSION: We describe a large cohort of SMAD4 variant carriers in the context of HHT. Digestive complications are frequent, early and diffuse, justifying endoscopy every 2 years. The HHT phenotype, associating pulmonary and hepatic AVMs, warrants systematic screening. Connective tissue disorders broaden the phenotype associated with SMAD4 gene variants and justify systematic cardiac ultrasound and skeletal complications screening.

RESUMO

Physical activity (PA), has a proven effect on overall health. The study assessed the difference in glomerular filtration rate (GFR) over one year in non-dialysis renal failure patients between those who practiced exercise (P) and those who did not (NP). Patients were categorised as P or not P using the Global Physical Activity Questionnaire (GPAQ2), completed by telephone, at inclusion and at 12 months. Among the 259 patients included, 195 (75.3%) practiced a PA and 64 (24.7%) did not practiced. There was no significant difference in the slope of GFR decline from inclusion to month 12 between the two groups, p = 0.4107. Only the type of kidney seemed to be significantly associated with the slope of GFR decline over the 12 months (p = 0.0039). These results may be explained by a follow-up time too short to identify an effect of behavioural change on the progression of kidney disease.


L'activité physique (AP) a un effet démontré sur l'état de santé global. L'étude évaluait, chez des patients insuffisants rénaux non dialysés, la différence, sur un an, de l'évolution du débit de filtration glomérulaire (eDFG) entre ceux pratiquant une AP (P) et ceux n'en pratiquant pas (NP). Les patients ont été classés comme P ou NP grâce au questionnaire d'AP GPAQ2, passé par téléphone, à l'inclusion et à 12 mois. Parmi les 259 patients inclus, 195 (75,3 %) pratiquaient une AP et 64 (24,7 %) n'en pratiquaient pas. Il n'existe pas de différence significative sur la pente de décroissance du eDFG entre l'inclusion et le 12e mois (p = 0,4107). Le type de néphropathie semblerait associé significativement à cette pente de décroissance au cours des 12 mois (p = 0,0039). Ces résultats peuvent s'expliquer par une durée de suivi trop courte pour mettre en évidence un effet de la modification du comportement sur l'évolution de la maladie rénale.

RESUMO

BACKGROUND: Bevacizumab-a humanized monoclonal antibody-has been widely used to treat patients with hereditary hemorrhagic telangiectasia (HHT), but no randomized trial has yet been conducted. METHODS: This study is a double-blind multicenter randomized phase 2 trial with a 1:1 active-treatment-to-placebo ratio. We included patients over the age of 18 with a confirmed diagnosis and the need for at least four red blood cell (RBC) units transfused in the 3 months before study enrollment. Bevacizumab was administered at a dose of 5 mg/kg every 14 days with a total of six injections. The primary efficacy criterion was a decrease of at least 50% in the cumulative number of RBC units transfused in a 3-month period before and after treatment. RESULTS: A total of 24 patients (12 in each group) were included and randomized at 4 different centers. In intention-to-treat analysis, 63.6% of patients (7/11) in the bevacizumab group versus 33.3% of patients (4/12) in the placebo group decreased the number of blood transfusions by at least 50% (p = 0.22). Hemoglobin levels significantly improved at 6 months in the bevacizumab versus placebo group (p = 0.02). The pharmacokinetics study revealed that patients with high exposure to bevacizumab had a significant decrease in RBC transfusions (p = 0.03). Fifty-nine adverse events were observed, 34 in the placebo arm versus 25 in the bevacizumab arm. CONCLUSION: Though the present trial was underpowered, patients with HHT receiving bevacizumab required numerically fewer red blood cell transfusions than those receiving placebo, particularly those with high exposure.

RESUMO

Clinical trial data-sharing is seen as an imperative for research integrity and is becoming increasingly encouraged or even required by funders, journals, and other stakeholders. However, early experiences with data-sharing have been disappointing because they are not always conducted properly. Health data is indeed sensitive and not always easy to share in a responsible way. We propose 10 rules for researchers wishing to share their data. These rules cover the majority of elements to be considered in order to start the commendable process of clinical trial data-sharing: Rule 1: Abide by local legal and regulatory data protection requirementsRule 2: Anticipate the possibility of clinical trial data-sharing before obtaining fundingRule 3: Declare your intent to share data in the registration stepRule 4: Involve research participantsRule 5: Determine the method of data accessRule 6: Remember there are several other elements to shareRule 7: Do not proceed aloneRule 8: Deploy optimal data management to ensure that the data shared is usefulRule 9: Minimize risksRule 10: Strive for excellence.

RESUMO

PURPOSE: To evaluate mean change in best-corrected visual acuity (BCVA) at 52 weeks in patients with inflammatory choroidal neovascularization (CNV) treated with aflibercept. METHODS: We conducted a prospective non-comparative open-label trial. Following one mandatory intravitreal injection of aflibercept, patients were treated under a pro re nata (PRN) dosing regimen with monthly visits. RESULTS: A total of 19 patients were included, but one presented exclusion criteria; 16 patients were followed for the whole 52-week study, and data for the primary endpoint analysis were available for 14. At baseline, mean BCVA and mean central retinal thickness (CRT) were 64.53 (±19.64) letters and 351.79 (±97.77) µm, respectively. At 52 weeks, the mean change in BCVA was +9.50 (±12.90) letters [95%CI = +2.05-+16.95]. One patient had lost more than 15-letters at 24 weeks, and another one at 52 weeks. CRT change was -62.77 (±100.73) µm at 24 weeks and -66.53 (±97.47) µm at 52 weeks. There was a mean number of 3.56 (±3.29) intravitreal injections at 52 weeks (min = 1; max = 12). No serious ocular adverse events related to the treatment were reported. CONCLUSIONS: Our study shows that aflibercept is clinically effective, both anatomically and functionally in the treatment of inflammatory CNV. Following the first injection, the PRN strategy appears sufficient for treating most choroidal neovessels.

RESUMO

Although the underrepresentation of women in publication is a proven fact, there is no information on its counterpart: retractions. Using a previously studied cohort of retractions, the gender of the first author was checked manually to see if there was a similar pattern in the reasons for retraction for women and men authors. Out of 120 retractions, gender was identified for 113 (94.2%). A total of 42 (37.2%) retractions concerned publications authored by women and the reasons for retraction were significantly different between men and women authors. Overall, fraud and plagiarism accounted for 28.6 and 59.2% of women and men-authored retractions, respectively. These findings may have implications as regards training in responsible conduct in research; however, without further investigating larger cohorts and a better understanding of underlying mechanisms, it would be premature to draw any firm conclusions at this stage.

RESUMO

OBJECTIVE: To retrospectively describe a large series of pregnancies in women with hereditary haemorrhagic telangiectasia followed in our reference centre, plus neonatal outcomes, to better understand the risks of complications and to improve their prevention. DESIGN: A retrospective descriptive study conducted through a phone questionnaire. SETTING: Reference centre for hereditary haemorrhagic telangiectasia in Lyon, France. POPULATION: Women meeting the following criteria: (1) alive and aged ≥18 years; (2) with a definite clinical and/or genetic diagnosis of hereditary haemorrhagic telangiectasia; and (3) with at least one full-term pregnancy. MAIN OUTCOME MEASURES: Maternal and perinatal outcomes of pregnancies in women with hereditary haemorrhagic telangiectasia. RESULTS: Five hundred and sixty-two pregnancies were reported in 207 women with hereditary haemorrhagic telangiectasia. A total of 271 complications (48.2%) were registered. Of these, 149 (55%) non-specific complications, 110 (40.6%) non-severe specific complications and 12 (4.4%) severe specific complications were registered. There were four cases of haemoptysis and two cases of transient ischaemic attack related to pulmonary arteriovenous malformations. Four patients had severe decompensated dyspnoea, related to pulmonary arteriovenous malformations in three cases and to pulmonary arteriovenous malformations associated with severe hepatic arteriovenous malformations in one case. Hepatobiliary necrosis occurred in one case. Epidural or spinal anaesthesia was performed in 139 of 452 deliveries (31%), without complications. There were 12 reports of congenital anomalies in 461 live births (3%). CONCLUSIONS: Most pregnancies in hereditary haemorrhagic telangiectasia women are uneventful; complications are rare but can be severe. Women thus need to be educated about screening and possible pregnancy-related risks before becoming pregnant.

RESUMO

PURPOSE: The aim of the present study was to determine whether microperimetric parameters could predict the progression of an eye at high risk of age-related macular degeneration (AMD) at 24 months. METHODS: We conducted a multicentric prospective non-comparative open-label study including patients with one eye in stage 4 of the Age-Related Eye Disease Study Group (AREDS) classification, and the other eye in AREDS stage 3 (study eye). A microperimetry examination (MAIA™, CenterVue, Padova, Italy) was performed at baseline and every 6 months during the 2-year follow-up. At the end of the follow-up, each study eye was classified as 'progressive' (i.e. AREDS stage 4) or 'non-progressive' (i.e. AREDS stage 3). RESULTS: A total of 147 patients were analysed, of which 30.6% progressed from AREDS stage 3 to stage 4. The microperimetry criterion 'mean retinal sensitivity' was significantly different at baseline between non-progressive and progressive eyes (p = 0.022), with lower values for the latter. With a threshold for mean retinal sensitivity set at 24.7 dB, diagnostic sensitivity was 80% [95%CI (65.4-90.4)], specificity was 30.4% [95%CI (21.7-40.3)], positive predictive value was 33.6% [95%CI (24.8-43.4)], and negative predictive value was 77.5% [95%CI (61.5-89.2)]. In the multivariate analysis including microperimetric parameters and other routine ophthalmologic examinations, mean retinal sensitivity was the only predictive parameter statistically associated with progression (p = 0.0004). CONCLUSIONS: Our findings are encouraging as regards the use of microperimetry, and mean retinal sensitivity value in particular, to predict the 2-year risk of progression to AREDS stage 4 eye.

RESUMO

Introduction: The aim of the study was to assess the clinical reliability of eGFR values estimated with a creatinine measurement from a point of care (StatSensor®) compared with measured GFR (mGFR) by a gold standard method. Methods: We prospectively included 113 patients undergoing renal function assessment. We compared eGFR using creatinine from capillary blood or venous blood measured by StatSensor® and measured GFR (mGFR) by Passing Bablok regression. Performance of eGFR was estimated by biais, precision and accuracy. Results: A total of 113 subjects were included. Median eGFR values were 59 (10-132), 52 (10-123) and 51 (10-131) ml/min/1.73 m2 for enzymatic, capillary and venous measurements, respectively. There was no difference between P30 and P10 for the three eGFR values (p = 0.11 and p = 0.1 respectively). StatSensor® eGFR tended to be underestimated compared to mGFR. For CKD stage 4/5 patients, concordance was 79 and 84% for eGFR with capillary creatinine and venous creatinine respectively. For mGFR< 60 ml/min/1.73 m2, concordance was 84 and 88% with capillary creatinine and venous creatinine respectively. Conclusion: The use of a handheld blood creatinine monitoring system with eGFR calculation provides a good estimation of GFR and allow to identify patients at high risk of acute kidney injury.

RESUMO

PURPOSE: Peritoneal carcinomatosis from appendiceal goblet cell carcinoma (A-GCC) is a rare and aggressive form of appendiceal tumor. Cytoreductive surgery (CRS) and hyperthermic intra peritoneal chemotherapy (HIPEC) was reported as an interesting alternative regarding survival compared to surgery without HIPEC and/or systemic chemotherapy. Our aim was to evaluate the impact of CRS and HIPEC for patients presenting A-GCC through an international registry. METHODS: A prospective multicenter international database was retrospectively searched to identify all patients with A-GCC tumor and peritoneal metastases who underwent CRS and HIPEC through the Peritoneal Surface Oncology Group International (PSOGI). The post-operative complications, long-term results, and principal prognostic factors were analyzed. RESULTS: The analysis included 83 patients. After a median follow-up of 47 months, the median overall survival (OS) was 34.6 months. The 3- and 5-year OS was 48.5% and 35.7%, respectively. Patients who underwent complete macroscopic CRS had a significantly better survival than those treated with incomplete CRS. The 5-year OS was 44% and 0% for patients who underwent complete, and incomplete CRS, respectively (HR 9.65, p < 0.001). Lymph node involvement and preoperative chemotherapy were also predictive of a worse prognosis. There were 3 postoperative deaths, and 30% of the patients had major complications. CONCLUSION: CRS and HIPEC may increase long-term survival in selected patients with peritoneal metastases of A-GCC origin, especially when complete CRS is achieved. Ideally, randomized control trials or more retrospective data are needed to confirm CRS and HIPEC as the gold standard in this pathology.

RESUMO

INTRODUCTION: Adherence to secondary preventive medications is often suboptimal in patients with stroke, exposing them to an increased risk of recurrent cerebral and/or cardiovascular events. Effective actions in the long term to improve adherence to medication are needed. The study will evaluate the efficacy of a collaborative multiprofessional patient-centred intervention conducted by a pharmacist on adherence to secondary preventive medication in stroke survivors. METHODS AND ANALYSIS: This is a multicentre cluster-randomised controlled trial. Two groups of 91 patients (intervention vs standard care) will be recruited. The clinical pharmacist intervention targeting secondary preventive medication will consist of three parts over 1 year: (1) an individual semi-structured interview at hospital discharge; (2) follow-up telephone interviews at 3, 6 and 9 months after discharge; and (3) a final individual semi-structured interview 1 year after discharge. Information on patient follow-up will be shared with the general practitioner and the community pharmacist by sending a report of each interview. The primary outcome is adherence to medication during the 12 months after hospital discharge, assessed using a composite endpoint: the medication possession ratio associated with a self-administered questionnaire. ETHICS AND DISSEMINATION: The local ethics committee, the national committee for use of personal data in medical research and the national data protection agency approved the study. The sponsor has no role in study design; collection, analysis and interpretation of data; or report writing. DISCUSSION: This pharmacist-led educational programme has the potential to significantly improve adherence to medication in stroke survivors which could lead to a decrease in recurrent cerebral and/or cardiovascular events. TRIAL REGISTRATION NUMBER: NCT02611440.

RESUMO

PURPOSE: To evaluate early predictive factors of visual loss in patients treated with anti-vascular endothelial growth factor (VEGF) injections under an as-needed regimen for neovascular age-related macular degeneration (AMD). DESIGN: Post hoc analysis from the randomized controlled trial Groupe d'Evaluation Français Avastin versus Lucentis (GEFAL). PARTICIPANTS: A total of 393 patients with neovascular AMD. METHODS: The present analysis is based on 1-year data from patients included in the study. Patients were separately categorized according to the best-corrected visual acuity (BCVA) change at 3 months and 1 year into 3 trajectories: (1) patients with no vision loss ≥5 letters at 3 months and 1 year (absence of loss ≥5 letters); (2) patients with no vision loss ≥5 letters at 3 months but loss ≥5 letters at 1 year (secondary loss ≥5 letters); and (3) patients with vision loss ≥5 letters at 3 months and 1 year (initial loss ≥5 letters). MAIN OUTCOME MEASURES: The following factors were evaluated at baseline and 3 months: age, sex, BCVA, presence of fluid, central macular thickness, angiographic choroidal neovascularization (CNV) subtype, CNV area measured in disc area on fluorescein angiography, and number of intravitreal injections. RESULTS: An absence of loss ≥5 letters was found in 225 patients (57.3%), a secondary loss ≥5 letters after 3 months was found in 109 patients (27.7%), and an initial loss ≥5 letters was found in 59 patients (15%). Baseline characteristics were comparable among the 3 groups except for the total CNV area, which was larger in the initial and secondary loss groups (P = 0.0412). At 3 months, a significant association was found between presence of subretinal fluid (SRF) (P = 0.0318) and vision loss ≥5 letters, and an even stronger significant association between the presence of intraretinal fluid (IRF) (P = 0.0066) and vision loss ≥5 letters. CONCLUSIONS: In the present study, we found that a large CNV area at baseline was significantly associated with initial or secondary loss of visual acuity ≥5 letters despite anti-VEGF injection. The presence of fluid, both SRF and IRF, at 3 months was found in patients with poorer trajectories.

RESUMO

PURPOSE: The principal aim of this pilot study was to investigate the concordance between the different stages of Age-Related Macular Degeneration (AMD), as determined by the simplified classification of the Age Related Eye Disease Study Group (AREDS), and new evaluation criteria using a microperimetry system. METHODS: A complete eye examination and a microperimetry MAIATM (Macular Integrity Assessment, CenterVue, Padova, Italy) examination was performed on 59 eyes with early, intermediate or advanced AMD. We analysed 19 evaluation criteria for every clinical group category. RESULTS: There were 20 female and 12 male participants included with a median age of 74 years (min: 54, max: 87). Thirteen eyes (22%) were classified as category 1, 11 eyes (18.6%) as category 2, 17 eyes (28.8%) as category 3 and 18 eyes (30.6%) as category 4 AMD.All evaluated microperimetry criteria related to retinal sensitivity were found to have a statistically significant difference among the stages (p < 0.05). Fixation stability was unstable in 55.6% of the eyes classified as stage 4 (p = 0.001). The analysis of the distance between the two PRLs - PRL_initial and PRL_final was larger for the stage 4 (p = 0.0258). The mean sensitivity in stages 2 and 3 correlated with the presence or not of reticular pseudodrusen (p = 0.0137). CONCLUSIONS: The mean sensitivity and the categorized sensitivity (set to 25, 15 and 5 dB), the five higher and lower stimuli sensitivity appeared to be the most sensitive criteria to differentiate the four AMD categories. Microperimetry provides a new reproducible method of anatomical-functional macular analysis.

RESUMO

PURPOSE: To evaluate the mean change in visual acuity at 52 weeks in patients with idiopathic choroidal neovascularization treated with aflibercept. METHODS: We conducted a prospective noncomparative open-label Phase-II trial. The dosage regimen evaluated in this study was structured into two periods: (1) from inclusion to 20 weeks: a treat-and-extend period composed of three mandatory intravitreal injections, and complementary intravitreal injections performed if needed; (2) from 21 weeks to 52 weeks: a pro re nata period composed of intravitreal injections performed only if needed. RESULTS: A total of 19 patients were included, and 16 completed the 52-week study. At baseline, the mean best corrected visual acuity was 66.56 (±20.72) letters (≈20/50 Snellen equivalent), and the mean central retinal thickness was 376.74 µm (±93.77). At 52 weeks, the mean change in the best-corrected visual acuity was +19.50 (±19.36) letters [95% confidence interval = +9.18 to +29.82]. None of the patients included lost ≥15 letters at 24 weeks or 52 weeks. The mean change in central retinal thickness was -96.78 µm (±104.29) at 24 weeks and -86.22 µm (±112.27) at 52 weeks. The mean number of intravitreal injections was 5.4 (±3.0) at 52-weeks. No ocular serious adverse events related to the treatment were reported. CONCLUSION: The present analysis shows clinically significant functional and anatomical treatment effect of aflibercept in case of idiopathic choroidal neovascularization. The treat-and-extend regimen proposed after the first injection seems adequate to treat most neovessels.

RESUMO

Despite a keen interest in clinical research, most paramedical professionals are unwilling to play an active role. Our objective was to explore paramedical professionals' representations of research. Using an existing database of final year paramedical students (speech therapy, occupational therapy, psychomotricity, audiometry, physiotherapy, orthoptics), we deployed a qualitative approach composed of two successive steps: (1) a free word association task, and (2) semi-structured individual interviews. Out of the 54 students who agreed to be contacted, we received 21 responses to the free word association questionnaire, and 11 interviews were conducted. The hierarchical evocation matrix revealed that the scientific representation of research is based on words defining the research and the purpose of the research. "Collaboration" was identified as being an essential part of the research process. The central core of the representation is coherent with all its components perceived as positive. The content analysis of the interviews showed a polarization around two key points: (1) participants are interested in accessing and using evidence in their practice (2) but feel less confident about and/or motivated to generate evidence themselves.

RESUMO

The number of patients with a history of melanoma who are awaiting a solid organ transplantation (SOT) is increasing. Few recommendations exist on the timing to transplantation after melanoma diagnosis. The aim of this study was to assess the melanoma recurrence-free survival after pretransplant melanoma (PTM). We conducted a multicenter ambispective observational study. Organ transplant recipients (OTR) with a history of PTM and complete AJCC staging were included. Thirty-seven patients (predominantly men with a renal allograft) were included. Five melanomas were in situ, 21 stage IA, 4 stage IB, 5 stage II, and 2 stage IIIB. The median post-transplantation follow-up time was 4 years. Sixty-two percent of patients were followed up more than 2 years. Recurrence-free survival since melanoma reached 89.9%, but varied significantly according to AJCC staging (P = 0.0129). Three patients presented a recurrence. Despite the rather limited sample size and a wide range of follow-up, our findings concerning the recurrence-free survival appear reassuring for in situ and stage IA PTM; accordingly, we suggest that a waiting time to transplantation is not mandatory in patients with in situ or stage IA PTM, especially whenever SOT is urgently needed. Caution is, however, needed for patients with higher stage.

RESUMO

Almost two in three patients who are aged 75 years and older and scheduled for surgery for colorectal cancer (CRC) are undernourished. Despite evidence that perioperative nutritional management can improve patients outcomes, international guidelines are still insufficiently applied in current practice. In this stepped-wedge cluster-randomized study of five surgical hospitals, we included 147 patients aged 70 years or older with scheduled abdominal surgery for CRC between October 2013 and December 2016. In the intervention condition, an outreach team comprising a geriatrician and a dietician visited patients and staff in surgical wards to assist with the correct application of guidelines. Evaluation, diagnosis, and prescription (according to nutritional status) were considered appropriate and strictly consistent with guidelines in 39.2% of patients in the intervention group compared to only 1.4% in the control group (p = 0.0002). Prescription of oral nutritional supplements during the perioperative period was significantly improved (41.9% vs. 4.1%; p < 0.0001). However, there were no benefits of the intervention on surgical complications or adverse events. A possible benefit of hospital stay reduction will need to be confirmed in further studies. This study highlights the importance of the implementation of quality improvement interventions into current practice for the perioperative nutritional management of older patients with CRC.

RESUMO

OBJECTIVES: The present multicenter Phase II study evaluated the rate of late grade ≥2 gastrointestinal (GI) toxicities at 3 years, after hypofractionated radiotherapy (HFR) of prostate cancer with injection of hyaluronic acid (HA) between the prostate and the rectum. METHODS: Between 2010 and 2013, 36 patients with low- or intermediate-risk prostate cancer were treated by HFR/IMRT-IGRT. 20 fractions of 3.1 Gy were delivered, 5 days per week for a total dose of 62 Gy. A transperineal injection of 10cc of HA was performed between the rectum and the prostate. Late toxicities were evaluated between 3 and 36 months after the end of treatment (CTCAE v4). RESULTS: Median pretreatment prostate-specific antigen was 8 ng ml-1. Among the 36 included patients, 2 were not evaluated because they withdrew the study in the first 3 months of follow-up, and 4 withdrew between 3 and 36 months, the per protocol population was therefore composed.Late grade ≥2 GI toxicities occurred in 4 (12%) patients with 3 (9%) Grade 2 rectal bleedings and one diarrhoea. Therefore, the inefficacy hypothesis following Fleming one-stage design cannot be rejected. None of the patients experienced late Grade 3-4 toxicities. Among the 30 patients completing the 36 months' visit, none still had a grade ≥2 GI toxicity. Late grade ≥2 genitourinary (GU) toxicities occurred in 14 (41%) patients. The most frequent toxicities were dysuria and pollakiuria. Four patients still experienced a grade ≥2 GU toxicity at 36 months.The biochemical relapse rate (nadir +2 ng ml-1) was 6% (2 patients). Overall, HA was very well tolerated with no pain or discomfort. CONCLUSION: Despite the inefficacy of HA injection was not rejected, we observed the absence of Grade 3 or 4 rectal toxicity as well as a rate of Grade 2 rectal bleeding below 10% at 36 months of follow-up. Late urinary toxicities are the most frequent but the rate decreases largely at 3 years. ADVANCES IN KNOWLEDGE: With an injection of HA, hypofractionated irradiation in 4 weeks is well tolerated with no Grade 3 or 4 GI toxicity and a rate of Grade 2 rectal bleeding below 10% at 36 months of follow-up.

RESUMO

Background: Increased preoperative delay in patients with hip fractures may be responsible for increased morbidity and mortality. We hypothesized that a strategy of reversal of vitamin K antagonist (VKA) by prothrombin complexes concentrates (PCCs), as compared to vitamin K, is safe and reduces preoperative delay and hospital length of stay (LOS). Methods: In this pilot study, we reviewed the records of patients admitted to a university-affiliated hospital for hip fracture between Jan. 1, 2012, and Dec. 31, 2016, who were taking VKA. Patients were stratified according to reversal strategy (vitamin K v. PCC). Adverse effects, time to surgery, LOS and mortality were collected from the electronic medical record and were compared between the 2 study groups and a control group not treated with VKA. Results: A total of 141 patients were included in the study: 65 in the vitamin K group, 26 in the PCC group and 50 in the control group. The median preoperative delay in the PCC group (20 h [interquartile range (IQR)] 13-25 h]) and the control group (20 h [IQR 15-33 h]) was lower than that in the vitamin K group (45 h [IQR 31-52 h]) (p < 0.001). Patients in the PCC group had a shorter median hospital LOS than those in the vitamin K group (6 d [IQR 4-9 d] v. 8 d [IQR 6-11 d], p < 0.05). No difference was observed in the proportion of patients who received a red blood cell transfusion, or had thrombotic or hemorrhagic complications. No difference in mortality at 12 months was observed between the groups. Conclusion: In patients with hip fracture, the use of PCCs as compared to vitamin K to reverse the effect of VKA significantly reduced preoperative delay and hospital LOS, and was not associated with an increase in the rates of thrombotic or hemorrhagic complications. Prospective studies involving a greater number of patients are required to confirm these promising results.


Contexte: L'allongement du délai préopératoire chez les patients atteints d'une fracture de la hanche pourrait expliquer l'augmentation de la morbidité et de la mortalité. Selon notre hypothèse, une stratégie d'inversion des antagonistes de la vitamine K (AVK) au moyen de concentrés de complexes prothrombiques (CCP), plutôt que de vitamine K, est sécuritaire et réduit le délai préopératoire et la durée du séjour hospitalier. Méthodes: Pendant cette étude pilote, nous avons passé en revue les dossiers de patients sous AVK admis dans un centre universitaire pour fracture de la hanche entre le 1er janvier 2012 et le 31 décembre 2016. Les patients ont été stratifiés selon la stratégie d'inversion choisie (vitamine K c. CCP). Les effets indésirables, le délai préopératoire, la durée du séjour hospitalier et la mortalité ont été recueillis à partir des dossiers médicaux électroniques et ont été comparés entre les 2 groupes de l'étude et un groupe témoin non sous AVK. Résultats: En tout, 141 patients ont été inclus dans l'étude, 65 dans le groupe sous vitamine K, 26 dans le groupe sous CCP et 50 dans le groupe témoin. Le délai préopératoire médian pour le groupe sous CCP (20 h [éventail interquartile (ÉIQ)] 13­25 h]) et le groupe témoin (20 h [ÉIQ 15­33 h]) a été plus bref que pour le groupe sous vitamine K (45 h [ÉIQ 31­52 h]) (p < 0,001). Les patients du groupe sous CCP ont eu un séjour hospitalier médian plus bref que les patients du groupe sous vitamine K (6 j [ÉIQ 4­9 j] c. 8 j [ÉIQ 6­11 j]) (p < 0,05). Aucune différence n'a été observée quant à la proportion de patients ayant reçu une transfusion de culot globulaire ou ayant manifesté des complications thrombotiques ou hémorragiques. Aucune différence quant à la mortalité à 12 mois n'a été observée entre les groupes. Conclusion: Chez les patients atteints d'une fracture de la hanche, l'utilisation des CCP plutôt que de la vitamine K pour inverser l'effet des AVK a significativement abrégé le délai préopératoire et la durée du séjour hospitalier, et n'a pas été associée à une augmentation des taux de complications thrombotiques ou hémorragiques. Des études prospectives sur un plus grand nombre de patients sont nécessaires pour confirmer ces résultats prometteurs.
