Proposal of model for personalized early adapted cancer screening in people living with HIV: experience of "Gaetano Martino" Hospital University of Messina

Human immunodeficiency virus (HIV) infection has historically been related to the development of specific cancers, some of which are so closely linked to the infection, such as Kaposi's Sarcoma (KS), that they have earned the name Acquired Immuno-Deficiency Syndrome (AIDS)-defining cancers (ADCs). While the development of antiretroviral therapy (ART) has decreased the incidence of AIDS-defining cancers, the resulting aging of people living with HIV (PLWH) highlighted an increased occurrence of other forms of cancer. At the "Gaetano Martino" hospital in Messina, we developed a multidisciplinary approach by creating a bridge between the Oncology Unit and the Infectious Diseases Unit to carry out screening and a more rapid diagnostic and therapeutic journey for cancers in PLWH. The goal is to improve the diagnosis of various types of cancer by involving other professionals, such as gastroenterologists and gynecologists, to ensure faster access to treatment and, therefore, a greater chance of survival. In addition, our multidisciplinary approach has also included vaccine screening, offered by the "Gaetano Martino" hospital and useful for preventing the development of specific forms of cancer in the entire population and particularly in PLWH.

Locally advanced squamous cervical carcinoma (M0): management and emerging therapeutic options in the precision radiotherapy era

Squamous cervical carcinoma (SCC) requires particular attention in diagnostic and clinical management. New diagnostic tools, such as (positron emission tomography-magnetic resonance imaging) PET-MRI, consent to ameliorate clinical staging accuracy. The availability of new technologies in radiation therapy permits to deliver higher dose lowering toxicities. In this clinical scenario, new surgical concepts could aid in general management. Lastly, new targeted therapies and immunotherapy will have more room in this setting. The aim of this narrative review is to focus both on clinical management and new therapies in the precision radiotherapy era.

Pancreatic Neuroendocrine Tumor (Pan-NET) Presented by Abdominal Pain: A Case Report and Literature Review

A pancreatic neuroendocrine tumor (Pan-NET) is a rare neoplasm originating in the neuroendocrine system. Carcinoid syndrome occurs in approximately 19% of patients with functional Pan-NETs, typically when liver metastases occur. In this paper, we describe the case of a patient with a low-grade non-functional Pan-NET, but with a typical clinical presentation of carcinoid syndrome. An 81-year-old male was admitted to our Department of Internal Medicine at Cannizzaro Hospital (Catania, Italy) because of the onset of abdominal pain with nausea, loose stools, and episodic flushing. Firstly, an abdominal contrast-enhanced CT scan showed a small pancreatic hyper-vascular mass; then, a gallium-68 DOTATOC integrated PET/CT revealed an elevated expression of SSTR receptors. Serum chromogranin A and urinary 5-HIAA measurements were negative. We performed an endoscopic ultrasonography (EUS) by a fine-needle biopsy (EUS-FNB), allowing the immunostaining of a small mass (0.8 cm) and the diagnosis of a low-grade (G1) non-functional Pan-NET (NF-Pan-NET). Surgery was waived, while a follow-up strategy was chosen. The early recognition of Pan-NETs, although rare, is necessary to improve the patient's survival. Although helpful to allow for immunostaining, EUS-FNB needs to be warranted in future studies comparing EUS-FNB to EUS-FNA (fine-needle aspiration), which is, to date, reported as the tool of choice to diagnose Pan-NETs.

MAFLD: a multisystem disease

Nonalcoholic fatty liver disease (NAFLD), affecting about 25% of general population and more than 50% of dysmetabolic patients, is an emerging cause of chronic liver disease and its complications. Recently, an international consensus of experts proposed to rename this disease as 'Metabolic dysfunction-Associated Fatty Liver Disease' (MAFLD) to focus on the bidirectional interplay between fatty liver and metabolic alterations and to stress the need of assessing fatty liver independently from alcohol consumption and other coexisting causes of liver disease. The peculiarity of NAFLD/MAFLD lies in the presence of a higher risk of not only - as expected - liver-related events but also of extrahepatic events, mostly cardiovascular and cancers. Available evidence suggests that these associations are not only the expression of sharing the same risk factors but shed light about the ability of NAFLD/MAFLD and particularly of its progressive form - nonalcoholic/metabolic dysfunction-associated steatohepatitis - to act as an independent risk factor via promotion of atherogenic dyslipidemia and a proinflammatory, profibrogenic, and procoagulant systemic environment. The present review summarizes available epidemiological and clinical evidence supporting the concept of NAFLD/MAFLD as a multisystemic disease, and highlights potential explanatory mechanisms underlying the association between NAFLD/MAFLD and extrahepatic disorders.

Effect of pharmacological interventions and placebo on liver Histology in nonalcoholic steatohepatitis: A network meta-analysis

BACKGROUND

The aims of this study were to quantify the histological improvement and its risk factors in patients with NASH enrolled in the placebo arms of randomized controlled trials (RCTs), and to indirectly compare the effect of several investigational drugs for NASH on validated histological outcomes.

DATA SYNTHESIS

A comprehensive search was conducted to detect phase 2 and 3 RCTs comparing pharmacological interventions in patients with NASH. According to Food and Drug Administration (FDA) recommendations, primary outcomes included: 1) NASH resolution without worsening of fibrosis; 2) At least 1-point reduction in fibrosis without worsening of NASH. Meta-analysis and meta-regressions were conducted on placebo arms, while network meta-analysis was performed on intervention arms. A total of 15 RCTs met the eligibility criteria. The meta-analysis on placebo arms showed a pooled estimate rate of 17% (95%C.I. 12%-23%;I² = 86%; p < 0.01) for NASH resolution without worsening of fibrosis and of 21% (95%C.I. 13%-31%;I² = 84%; p < 0.01) for ≥1stage improvement of fibrosis without worsening of NASH. Phase 3 (vs Phase 2)RCTs, older age and higher AST levels were significantly associated with progression of liver disease by univariate meta-regression. At network meta-analysis, Semaglutide (P-score 0.906), Pioglitazione alone (score 0.890) and plus Vitamin E (0.826) had the highest probability of being ranked the most effective intervention for NASH resolution without worsening of fibrosis, while Aldafermin (0.776), Lanifibranor (0.773) and Obeticholic acid (0.771) had the highest probability to achieve ≥1 stage of fibrosis improvement without worsening of NASH.

CONCLUSION

This study confirms the heterogeneity of histological progression of untreated patients with NASH and provides evidence to stratify patients according to identified risk factors in future RCTs of combination therapies. PROSPERO CRD42021287205.

POS1027 APREMILAST EFFICACY IN REAL WORLD SETTINGS: RESULTS FROM AN ITALIAN MULTI-CENTER OBSERVATIONAL STUDY

Background

Apremilast, an inhibitor of the phosphodiesterase 4, is indicated for Psoriatic Arthritis (PsA) treatment. The 3 years retention rate, an outcome indirectly related to efficacy, observed in clinical trials [1] is 55,5%. A single subsequent real world setting study [2] suggested a lower efficacy as it reported that the six months retention rate was about 57%.

Objectives

The main aim of this retrospective observational study is the assessment of apremilast 3 years retention rate in a real world PsA patients’ cohort. Moreover, the secondary objective is reporting the reasons of apremilast suspension and the most relevant factor related to treatment persistence.

Methods

In thirteen Italian rheumatological referral centers, all PsA consecutive patients who received apremilast were enrolled. Anamnestic data, treatment history and PsA disease activity (DAPSA) at baseline and after 6 and 12 months were recorded. The Kaplan-Meier curve and the Cox analysis computed the apremilast retention rate and treatment persistence-related risk factors. A p-value < 0.05 was considered statistically significant.

Results

The three-hundred-twenty-four enrolled patients (median age 60 [InterQuartile Range IQR 52-67] yrs; female prevalence 57,0%) median observation period was 17 [IQR 7-36] months (6848 patients-months). The apremilast retention rate at 6, 12 and 36 months was, respectively, 95%, 86% and 66% (Figure 1). The main discontinuation reasons were: primary inefficacy (40% of interruptions), secondary inefficacy (18%) and gastro-intestinal intolerance (17%%). The oligo-articular onset was the only factor associated to apremilast persistence (Hazard ratio 0.57 IQR 0.34-0.96). Sex, age, and sever comorbidities (cancer, chronic infections etc) were not related to treatment discontinuation. The basal DAPSA (24.1, IQR 18.5-32.0) decreased after 6 and 12 months (respectively 14.5, IQR 10.1-22.6 and 10.5, IQR 8,0-15.2). Remission or minimal disease activity (DAPSA < 15) was achieved after 12 months in 38.0% of patients.

Conclusion

Almost two third of PsA patients receiving apremilast were still in treatment after 3 years. The study’s data, confirmed its efficacy and safety profile. Apremilast appear a good treatment choice in patients with oligo articular PsA or burdened by severe comorbidities.

AB0341 EFFICACY AND DRUG SURVIVAL AFTER MULTIPLE-SWITCHING FROM ADALIMUMAB ORIGINATOR TO THE BIOSIMILARS ABP501 AND SB5: A REAL-LIFE STUDY

Background

AntiTNF-α biosimilars are broadly available for the treatment of inflammatory arthritis. There are a lot of data concerning the maintenance of clinical efficacy after switching from originators to biosimilars. However, there is lack of data on the switch between biosimilars. The current evidence on the safety, efficacy, and immunogenicity of switching multiple times from a biosimilar to another biosimilar comes from a limited number of randomized-controlled trials and real world evidence studies.

Objectives

The aim of our work was to evaluate the disease activity trend after multiple switching from ADA originator-Humira (oADA) to its biosimilars (bsADA; ABP 501 and SB5 subsequently) in a cohort of inflammatory arthritis patients.

Methods

In this real-life study, we selected patients with clinical diagnosis of rheumatoid Arthritis (RA), psoriatic Arthritis (PsA) and ankylosing spondylitis (AS). Patients had been previously treated with oADA and switched to the bsADA (first ABP 501 and then SB5). At each outpatient visit, we recorded demographic features (age, sex, and time since diagnosis) and the following disease activity measures: DAS28, DAPSA, BASDAI and the HAQ. Rheumatoid factor (RF), anti-citrullinated protein antibody (ACPA), C-reactive protein (CRP) and HLAB27 were also measured over the observational period (visits 0, 12, 24 and 36 months). The disease activity was evaluated during the year before the introduction of the bsADA, and then evaluated in the following 36 months during the first and the second bsADA treatment. We also examined whether some baseline characteristics, such as the duration of ADA treatment, concomitant therapy, comorbid disease and baseline disease activity, could influence the bsADA discontinuation.

Results

We evaluated the 3-year drug survival and efficacy of the multiple switch of bsADA in RA, PsA and AS patients, previously treated with oADA in 127 patients (Table 1). All the patients enrolled underwent a first switch lasting one year and then a second switch with a follow up of one year too. The 1-year retention rate for ABP501 was 84.4%, 78% and 76% in AS, RA and PsA patients, respectively. The 1-year retention rate for SB5 was 82.1%, 78,7% and 77,5% in AS, RA and PsA patients, respectively. Disease activity, as measured by DAS28, DAPSA and BASDAI remained stable over the 3 years (Figure 1). Comorbid disease (HR: 3.04, p < 0.001) and HAQ at baseline (HR: 2.12, p = 0.001) significantly increased the risk of ADA discontinuation, while previous ADA duration was positively associated with bsADA retention rate (HR: 0.83, p = 0.0024). 27.4% patients left the study due to the interruption of the bsADA, 76.5% discontinued due to inefficacy and 23.5% due to adverse events.

The Italian Society for Rheumatology recommendations for the management of axial spondyloarthritis

Over the last few years, the landscape of treatments for axial spondyloarthritis (SpA) has been rapidly evolving, urging international scientific societies to draft or update existing clinical practice guidelines (CPGs) on the management of axial SpA. The Italian Society for Rheumatology (SIR) committed to provide revised and adapted evidence- and expert-based recommendations for the management of patients with axial SpA in Italy. A systematic approach to the adaptation of existing CPGs - the ADAPTE methodology - was adopted to obtain updated recommendations suitable for the Italian context. A systematic literature search was performed in Medline and Embase databases to find international CPGs and consensus statements with recommendations for the management of axial SpA published in the previous five years. A working group composed of rheumatologists with proven experience in the management of axial SpA and methodologists identified the key research questions which guided study selection and data extraction. Guideline quality was assessed using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool. The Italian recommendations were developed by endorsing or adapting and rewording some existing recommendations. The draft of the recommendations was sent to a multidisciplinary group of external reviewers for comment and rating. Six original CPGs were selected and used to create this SIR CPG, which includes a final set of 14 recommendations covering the management of patients with axial SpA across the following domains: assessment, pharmacological and non-pharmacological treatment, and follow-up. The dissemination and implementation of these SIR recommendations are expected to support an evidencebased clinical approach to the management of patients with axial SpA in Italy.

The Italian Society for Rheumatology clinical practice guidelines for the diagnosis and management of fibromyalgia Best practices based on current scientific evidence

Fibromyalgia or fibromyalgia syndrome (FMS) is defined as a central sensitization syndrome characterized by the dysfunction of neurocircuits detecting, transmitting and processing nociceptive stimuli; the prevalent manifestation is musculoskeletal pain. In addition to pain, there are multiple accompanying symptoms, in common with other algo-dysfunctional syndromes, which are reflected in a broad spectrum of somatic, neurocognitive and neuro-vegetative manifestations. An evidence-based approach is essential in FMS management, in order to improve patient health and to reduce its social burden. Since in the last ten years new international guidelines for clinical practice (Clinical Practice Guidelines or CPGs) concerning FMS diagnosis and pharmacological/ non-pharmacological management have been published, the Italian Society of Rheumatology (SIR) has decided to adapt them to the Italian national setting. The framework of the Guidelines International Network Adaptation Working Group was adopted to identify, appraise (AGREE II), synthesize, and customize the most recent CPGs on FMS to the needs of the Italian healthcare context. A working group of rheumatologists from SIR epidemiology unit and FMS experts identified relevant clinical questions to guide the systematic review of the literature. The target audience of these CPGs included physicians and healthcare professionals who manage FMS. The adapted recommendations were finally assessed by an external multidisciplinary panel. From the systematic search in databases (Pubmed/Medline, Embase) and grey literature, 6 CPGs were selected and appraised by two independent raters. The combination of the scientific evidence underlying the original CPGs with expert opinion lead to the development of 17 recommendations. The quality of evidence for each recommendation was reported and their potential impact on clinical practice was assessed. These SIR recommendations are expected to be a valuable aid in the diagnosis and treatment of FMS, as they will contribute to disseminate the best practice on the basis of the current scientific evidence.

POS0230 INTESTINAL MICROBIOTA CHANGES TNF-INHIBITORS INDUCED IN IBD-RELATED SPONDYLOARTHRITIS

Background:

the close relationship between joints and gut inflammation has long been known and several data suggest that the dysbiosis could represents the link between Spondyloarthritis (SpA) and Inflammatory Bowel Diseases (IBD). To date, the manipulation of the intestinal microbiota is considered the key to the cure or control of the natural history of several pathologies sustained or favored by dysbiosis. The introduction of biologic drugs, in particular Tumor Necrosis Factor inhibitors (TNFi), revolutionized the management of both these diseases, thanks to the strong inhibition of inflammation and partially indirectly with mechanisms not yet fully clarified. While the impact of conventional drugs on gut microbiota is well known poor data are available about TNFi.

Objectives:

to investigate the impact of TNFi on gut microbiota.

Methods:

we included CD or UC patients fulfilling criteria for axial or peripheral SpA (ASAS 2009) on a typical Mediterranean diet, naïve to biologics needing TNFi. Clinical history, physical examination, instrumental examinations, biochemical examination including C-reactive protein (CRP), erhytrocyte sedimentation rate (ESR), HLA-B27 and fecal calprotectin at the baseline and after 6 months were performed. TNFi included infliximab and adalimumab. Fecal samples were collected by patients themselves by 24 hours before the start of the therapy. The processing was performed through metagenomic NGS (next generation sequencing) including the amplification of the V3 and V4 regions of the 16S (V3 and V4) and sequencing on the Illumina MiSeq platform. All patients received the treatment at least until week 24. Clinical disease indices included Visual Analogue Scale (VAS)-pain and Visual Analgue Scale(VAS)-disease activity for all patients, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for axial involvement, clinical disease activity index (CDAI) and Health Assessment Questionnaire-Disability Index (HAQ-DI) for peripheral involvement, Harvey-Bradshaw Index for CD (HBI), or partial Mayo (pMAYO) score for UC, were assessed at baseline and at the end of the study. The study was approved by the ethics committee (approval code 0056924).

Results:

we evaluated 20 patients affected by enteropatic arthritis, naïve for biologic drugs, treated with TNFi. After six months of therapy we observed a significant increase in Lachnospiracae family (Δ +10.3, p 0.04) and in Coprococcus genus (Δ +2.8, p 0.003). We also observed a decrease trend in Proteobacteria (Δ -8.0 p 0.095) and Gammaproteobacteria (Δ -9, p 0.093) and an increase trend in Clostridia (Δ +8.2 p 0.083). We didn’t find differences between TNFi responders (SpA improvement or IBD remission achieved) and not responders in terms of alpha and beta-diversity.

Conclusion:

the decrease of Proteobacteria and the increase of Lachnospiraceae and Coprococcus is consistent with the hypothesis that TNFi therapy, by decreasing inflammation, tends to restore the intestinal eubiosis. However further studies on larger cohort incuding the evaluation of gut virota and micobiota will be necessary to definitively clarify the effects of TNFi on the composition and function of the gut microbiota.

OP0223 DEVELOPMENT AND PRELIMINARY VALIDATION OF ULTRASONOGRAPHIC DISEASE ACTIVITY AND DAMAGE SCORES IN PSORIATIC ARTHRITIS PATIENTS: RESULTS FROM THE UPSTREAM (ULTRASOUND IN PSORIATIC ARTHRITIS TREATMENT) STUDY

Background:

The UPSTREAM (NCT03330769) is a 24-month multi-center prospective cohort study that primarily aims to evaluate the additional value of musculoskeletal ultrasound (msk-US) over clinical examination in predicting 6-month minimal disease activity in Psoriatic Arthritis (PsA). (1)

Objectives:

To develop and preliminarily validate an activity msk-US score and a damage msk-US score for PsA using the UPSTREAM database.

Methods:

Patients classified with PsA according to CASPAR criteria and starting a new course of therapy for clinically active peripheral joint disease were eligible. The information regarding objectives, study design, clinical and US assessment has already been published (1). The msk-US examination was performed in 42 joints, 36 tendons, 12 entheses and 2 bursae defined through a web-based exercise (2). The sonographic elementary lesions were allocated to disease activity [i.e. synovitis (sy), tenosynovitis (ts), peritendinitis (pt), bursitis (bs) all evaluated both in Grey Scale (GS) and Power Doppler (PD) and active enthesitis (en)] and to damage (i.e. joint erosion, bone proliferation, tendon tear, enthesophyte, calcification and irregular enthesis bone profile). Hands and feet X-ray were assessed using the modified Sharp-Van der Heijde (mSVH) score. A principal component (PC) analysis (PCA) was performed for each score and the number of PCs was defined by means of parallel analysis using baseline data. Each PC was normalized (n) taking into account the proportion between the observed value (e.g. sy-GS count) and the maximum expected value (e.g. 42 for sy-GS). Spearman’ correlation was used to investigate the construct and discrimination validity of the new scores.

Results:

Between February 2017 and May 2020, 312 PsA patients (155 men), with a mean (SD) age of 52.8 13.4, were enrolled from 19 centers; 22 expert sonographers were involved with substantial agreement for US lesions evaluated (k ≥0.7). The median [IQR] disease duration was 1.3 [0.1-6.1] years and the median [IQR] tender joint and swollen joint counts were 6 [3-13] and 2 [1-5], respectively. The weight derived from PCA for each sonographic lesions and the final equation for calculating the scores are reported in Figure 1 (1A activity and 1B damage). The final msk-US activity score [n(ts-GS + ts-PD)*2.87] + [n(bs-GS + bs-PD)*1.76] + [n(pt-GS + pt-PD)*1.43] + [n(active en)*1.00] + [n(sy-GS)*0.83] + [n(sy-PD)*0.45] has the best construct and discrimination validities according to a significant correlation with all clinical variables usually related to clinical activity (Table 1). The msk-US damage score correlated with mSVH score, HAQ and other clinical variables (Table 1).

POS0845 SCLERODERMIC HAND SENSOR: SMART TECHNOLOGY APPLIED TO RHEUMATOLOGY

Background:

Systemic Sclerosis (SSc) is an autoimmune rheumatic disease characterized by excessive production and accumulation of collagen in the skin and internal organs and by injuries to small arteries.

Impairment of the musculoskeletal system is one of the main causes of disability in SSc, indeed, about 90% of these patients have a loss of hand function. To date, the degree of skin involvement is evaluated through a semi-quantitative method called Rodnan Skin Score (RSS) or Modified-RSS (MRSS). However, MRSS is a method that has limitations related to the operator and his experience and does not provide information on joint mobility.

Arduino® is an open source integrated online platform based on easy to use hardware and software. It is a system for creating interactive projects by inserting a special configuration code, using the Arduino® development environment. Through this platform it is possible to create electronic devices with specific purposes to lead the possibility of integrating different kits (eg types of sensors) in relation to the object of study.

Objectives:

We have therefore created an electronic instrument (Sclerodermic Hand Sensor - SHS) independent operator and easily reproducible in order to measure the degree of mobility (flexion) of the hand in patients with SSc (Fig.1). The aim was to evaluate whether the SHS was able to highlight significant differences between patients with SSc and healthy patients.

Methods:

We recruited 20 female patients with SSc according to ACR criteria with a mean age of 50.8 ± 15.5 years and 20 healthy (HC) patients with a mean age of 44.3 ± 10.8 years (Tab.1), in order to test the effectiveness and sensitivity of the SHS tool.

Results:

The results showed a significant difference between the two groups of patients (SSc vs HC) independent of the measurement method used as expected (Goniometer SSc / HC: Δ45.80 ° p: 0.003 SHS SSc / HC: Δ65.17 ° p: 0.002, Fig.1c), however the device created with Arduino® proved to be more sensitive than the goniometric measurement in detecting the degree of joint flexion (p: 0.002). The flexion sensor, indeed, unlike the goniometer, evaluates the simultaneous articular excursion of the entire finger (MCF, IFP and IFD) and not just one segment (Fig.1).

Conclusion:

This technology application, thanks to the creation of dedicated electronic devices, allows the physicians to be supported in clinical practice with independent operating tools.

The tool we propose could be a valid support in accurately assessing the joint and indirectly skin involvement of sclerodactyly in this type of patient, especially in the context of a clinical trial to evaluate the efficacy of a treatment.

Further studies are needed to compare with other methods to assess hand disability in SSc such as the use of HAMIS (Hand Mobility in Scleroderma) test.

POS0090 RISK OF QT INTERVAL PROLONGATION ASSOCIATED WITH CHRONIC USE OF HYDROXYCHLOROQUINE IN RHEUMATIC PATIENTS AND THE EFFECT OF COTREATMENTS

Background:

Hydroxychloroquine (HCQ) has been used safely for over 60 years in rheumatic patients. However, following its recent use in covid-19 disease, its safety has been questioned, following controversial reports of cardiac toxicity1, possibly related to a prolongation of the QT interval2.

Objectives:

To explore the influence of chronic treatment with hydroxychloroquine on QT interval in rheumatic patients, and the possible effects of drug-to-drug interference3.

Methods:

12-lead electrocardiogram tracings were recorded with standard equipment in 229 ambulatory patients (SLE = 53, RA = 52, SSc = 56, UCTD = 38, Others = 30). The present analysis was performed on corrected QT intervals (QTc) calculated according to Framingham formula (QTc = QT+0.154 (1−RR)), with ULN = 449 ms in males, and 467 ms in females. Estimated glomerular filtrate rate (eGFR) was calculated from serum creatinine with the CKD-EPI equation. The influence on QTc values of demographic variables, chronic (≥3 months) HCQ treatment, and of the use of selected comedications -Statins, Angiotensin Converting Enzyme inhibitors (ACEi), Angiotensin Receptor Blockers (ARBs), Selective Serotonin Reuptake Inhibitors (SSRIs), Proton-Pump Inhibitors (PPI), Calcium Channel Blockers (CCBs) – were evaluated by parametric or non parametric statistical methods, as appropriate. All statistic al analyses were performed with the IBM SPSS statistical package version 25.

Results:

Table 1.

Demographic variables, and the use of evaluated comedications were not different in HCQ+ and HCQ- patients (Table 1). In the whole population, the QTc mean duration was 416.72 ± 20.70 ms, and was correlated with age (r = 0.215, p= 0.001), but not with gender (p = 0.548), eGFR (r = -0.93, p = 0.163), or disease (p = 0.092). In only 4 patients (HCQ+: 3 (2.3%) – HCQ-: 1 (1%), p = 0.639) QTc duration was above ULN.

QTc duration was not associated with the use of Statins, ACEi, ARBs, or SSRIs (p = 0.454, 0.276, 0.475, and 0.131 respectively), but was significantly prolonged in patients treated with HCQ (421.26 ± 19.19 vs 410.55 ± 21.18 msec, p < 0.001), PPIs (420.57 ± 21.45 vs 410.89 ± 18.12 ms, p < 0.001), and CCBs (424.22 ± 25.97 vs 415.59 ± 19.62 ms, p < 0.033). Furthermore, as reported in Fig. 1, our data show a trend - albeit not statistically significant - towards an additive effect on QT prolongation of the association of PPIs and CCBs with HCQ, even more evident in the case of association of the 3 drug classes.

Conclusion:

In this study, the QTc interval was significantly prolonged in patients treated with hydroxychloroquine as compared to controls, although significant prolongation was extremely infrequent. Furthermore, our data revealed signs of drug-drug interference, suggesting that regular monitoring of the electrocardiogram is advisable in these patients, often undergoing cotreatment with multiple drugs.

POS1243 TELEMEDICINE AND MANAGEMENT OF THE PATIENT AFFECTED BY GIANT CELL ARTERITIS DURING THE COVID-19 PANDEMIC - TELEMACOV

Background:

Giant cell arteritis (GCA) is the most common primary systemic vasculitis in western countries with the highest incidence among persons 70–79 years of age. Treatment has been with glucocorticoids (GCs) alone for many decades but recently Tocilizumab (TCZ) has demonstrated efficacy in reducing GC dose and flare rates in patients with GCA. Therefore, both early diagnosis and regular monitoring are necessary for the correct management of GCA. The COVID-19 pandemic has led to decisions by the governments of the countries involved, aimed above all at reducing the contagion. This has also led to reductions in health activities, limiting them to those of urgency by reducing or canceling checkups involving the risk of a time gap which for the GCA meant the interruption of clinical monitoring and therapeutic adjustment. At the same time, the pandemic situation has stimulated remote monitoring activities, through telephone contacts or video calls carried out by the rheumatologist. EULAR identified a minimal data set aimed at research and for clinical use, which includes the main clinical and instrumental data to be taken into consideration in monitoring the patient. For many data a clinical examination is not necessary but an interview is sufficient. We activated the TELEMACOV protocol (TELEmedicine and Management of the patient affected by giant cell arteritis during the COVid-19 pandemic) monitoring the follow-up of patients affected by GCA through telemedicine tools in order to maintain an effective and risk-free follow-up in a pathology with a high risk of relapse.

Objectives:

The purpose of the study is to evaluate the effectiveness of telemedicine in the follow-up of the patient with GCA.

Methods:

We evaluated patients (pts) with a clinical diagnosis of GCA (received in previous periods) who were admitted to the our Rheumatology Unit. They were monitored monthly by telephone from 9 March to 9 June 2020 (during lockdown). All patients were asked questions divided according to the sub-groups listed below:

- Onset of new symptoms or their recurrence

- Exams carried out

- Current therapy

- Satisfaction of telephone call

Results:

We performed 148 remote monitoring visits in 37 pts. The cohort was mainly composed by female (77,8%) and had a mean age of 71,85 ± 9,25 years. They were affected by GCA, with a mean duration of 5,3±2,3 months. The characteristics of these pts and the course of the disease are reported in Table 1. Pts treated with TCZ reduced their GC dose more than patients treated with GC alone (p: 0.032). Only one patient (treated with GC alone) had an ocular flare with the need to increase the dosage of the GC with good response and rapid improvement. Furthermore, all patients considered this type of monitoring very satisfactory according to the Likert scale (1-5) with mean 4,4±0,2.

Conclusion:

Our study has shown how telemedicine can be well used in pts with GCA as a possible alternative, for a limited period, to traditional visits, especially in a fragile population such as the elderly and more exposed to the risk of SARS-COV2 infection.

Health technology assessment through the six sigma approach in abdominoplasty: Scalpel vs electrosurgery

Abdominoplasty is a surgical procedure conducted to reduce excess abdominal skin and fat and improve body contouring. Despite being commonly performed, it is associated with a risk of complications such as infection, seroma, haematoma and wound dehiscence. To reduce the incidence of complications, different methods are used to create the abdominal flap, i.e., incision with a scalpel or electrosurgery. In this study, health technology assessment (HTA) using the Six Sigma methodology was conducted to compare these incision techniques in patients undergoing abdominoplasty. Two consecutively enroled groups of patients (33 in the scalpel group and 35 in the electrosurgery group) who underwent surgery at a single institution, the University of Campania "Luigi Vanvitelli", were analysed using the drain output as the main outcome for comparison of the incision techniques. While no difference was found regarding haematoma or seroma formation (no cases in either group), the main results also indicate a greater drain output (p-value<0.001) and a greater incidence of dehiscence (p-value=0.056) in patients whose incisions were made through electrosurgery. The combination of HTA and the Six Sigma methodology was useful to prove the possible advantages of creating skin incisions with a scalpel in full abdominoplasty, particularly a significant reduction in the total drain output and a reduction in wound healing problems, namely, wound dehiscence, when compared with electrosurgery, despite considering two limited and heterogeneous groups.

Prolonged iatrogenic thoracic duct chylous fistula in Neck Surgery: conservative management or surgery? A Literature review

BACKGROUND

Thoracic duct chylous fistula is a rare complication following neck surgery, especially for malignant disease. Despite its low incidence, it can be a life-threatening postoperative complication increasing the risk of infection, bleeding, hypovolemia, electrolyte imbalance, and malnutrition. Currently, the management of thoracic duct fistula is not standardized yet. It can range from conservative to surgical approaches, and even when surgery indication occurs, there is no unanimous agreement on timing and operative steps, so the surgical approach still remains mostly subjective, in accordance with clinical conditions of the patients and with surgeon's experience.

AIMS

The aim of the study was to search into Literature a common accepted behaviour in thoracic duct chylous fistula occurring.

METHODS

A literature review was carried out. Conservative treatments include fasting associated with total parental nutrition or low-fat diet, compressive dressings, and octreotide administration. If conservative treatment fails, in order to avoid dangerous consequences, functional repair of the thoracic duct injury with lymphovenous microanastomosis should be the preferred solution, rather than an approach that obliterates the thoracic duct or lymphatic-chylous pathways, such as thoracic duct embolization, therapeutic lymphangiography, and thoracic duct ligation.

CONCLUSIONS

In our experience, patients undergone thyroidectomy and neck dissection for thyroid-differentiated cancer, who report an unrecognized thoracic duct chylous fistula after surgery, must be treated via integrated conservative and surgical treatment. A literature review about thoracic duct chylous fistula following neck surgery, focusing on the current management and therapeutic approach, was furthermore carried out, in order to delineate the actual therapeutic options in case of thoracic duct chylous fistula occurrence.

Acromegaly and joint pain: is there something more? A cross-sectional study to evaluate rheumatic disorders in growth hormone secreting tumor patients

PURPOSE

The aim of the present study was to evaluate the rheumatic profile in acromegalic patients to better characterize joint pain.

METHODS

The immunological pattern (rheumatoid factor; antinuclear antibodies-ANA, extractable nuclear antigens-ENA-Ab; anti-citrullinated protein antibodies; erythrocyte sedimentation rate) was evaluated in 20 acromegaly subjects (AS) and 20 control subjects (CS). Bilateral joint ultrasound of hands/wrists and nail capillaroscopy were also performed.

RESULTS

Articular pain was more frequent in AS than in CS (p = 0.027). No difference was detected in immunological parameters. ANA and ENA-Ab were positive in only 10% of AS and in 5% of CS, while no difference was found in anti-citrullinated protein antibodies. No difference was detected between rheumatoid factor positivity, but threefold higher IgG were detected in AS compared to CS. The erythrocyte sedimentation rate was significantly higher in AS than CS (p = 0.040), while in AS, there was a trend in increased Power Doppler (PWD) articular uptake. The capillaroscopic evaluation showed a significant difference in almost each parameter (presence and number of tortuous capillaries, capillary enlargements, and hemorrhages), showing a moderate-to-severe microangiopathy in AS.

CONCLUSION

The results of our study suggest that joint damage in acromegaly has not an autoimmune etiology. Increased erythrocyte sedimentation rate levels and PWD alteration in acromegalic population reflect a possible inflammatory nature, while the capillaroscopic findings suggest a moderate-to-severe microangiopathy that could help to identify patients with a greater macroangiopathic risk.

Use of Hexyon/Hexacima/Hexaxim in preterm infants in Europe

Background

Worldwide 13 million babies born prematurely every year have increased susceptibility to infection and require adequate immunization. Hexavalent vaccines against diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B and Haemophilus influenzae type b are standard of care in pediatric vaccination and are particularly important for preterm infants. Hexyon® is registered in Europe since April 2013.

Methods

Considering birth data from official national databases and only countries with periods of exclusive use of Hexyon from 2013-19, we estimated the total number of preterm infants (&lt;37weeks GA) vaccinated with Hexyon.

Results

Since registration, Hexyon has been used in 23 European countries and exclusively used in the following: Austria, Feb-2017 to present; Belgium, Jul-2014 (Flanders)/Sep-2015 (Overall) to present; Bulgaria, Nov-2014 to Dec-2016; Croatia, Jan-2016 to present; Denmark, Feb-2016 to Apr-2017; Italy, Apr-2016 to present, exclusivity based on Regions; Macedonia, Oct-2015 to present; Norway, Feb-2017 to present; Romania, Apr-2015 to Dec-2017. The estimated total number of preterm infants during these periods of exclusive use is 183 000. Assuming 90% vaccination coverage, ∼164 700 preterm infants received at least 1 dose of this vaccine. From the analysis of the post-marketing safety data available to date, no new risk has been identified in preterm infants.

Conclusions

Hexyon has become a standard for hexavalent immunization in infants, regardless of the gestational age at birth. More than 90 million doses have been administered worldwide, including the estimated 164 000 preterm infants in the 9 European countries considered here. The EU Marketing Authorization granted in 2013 with no contraindication for use in preterm infants, was renewed in 2018 and the black triangle was removed confirming that the safety of Hexyon is well established. The marketing authorization holder continues to support evidence generation for use in preterm infants.

Key messages

Hexyon/Hexacima/Hexaxim has become a standard for hexavalent immunization in infants including for preterm infants (&lt;37weeks GA); around 164 000 preterm infants in 9 European countries received it. The safety of Hexyon/Hexacima/Hexaxim is well established, no new risk has been identified in preterm infants from the analysis of the post-marketing safety data available to date.

FRI0085 RETENTION RATE OF ADALIMUMAB AND ABP 501 IN THE TREATMENT OF A LARGE COHORT OF PATIENTS WITH INFLAMMATORY ARTHRITIS: A REAL LIFE RETROSPECTIVE ANALYSIS

Background:

The recent introduction of ABP 501, an adalimumab biosimilar, in treatment of rheumatic diseases was supported by a comprehensive comparability exercise with its originator. On the other hand observational studies comparing adalimumab and ABP 501 in inflammatory arthritis are still lacking.

Objectives:

To compare the clinical outcomes of the treatment with adalimumab, both originator and biosimilar, in a large cohort of patients affected by autoimmune arthritis in a real life setting.

Methods:

We retrospectively analysed the baseline characteristics and the retention rate in a cohort of patients who received at least a course of adalimumab (originator or biosimilar ABP 501) in eight Rheumatology Units from January 2003 to January 2020. We stratified the study population according to biosimilar use. Descriptive data are presented by medians (interquartile range [IQR]) for continuous data or as numbers (percentages) for categorical data. Drug survival distribution curves were computed by the Kaplan-Meier method and compared by a stratified log-rank test. P values ≤0.05 were considered statistically significant.

Results:

764 patients (53.4% female, median age 55 [44-65] years, median disease duration 60 [25-149] months) treated with adalimumab were included in the analysis. 308 (40.3%) were affect by rheumatoid arthritis, 244 (31.9%) by psoriatic arthritis, and 212 (27.7%) by axial spondylarthritis. 558 (73%) were treated with adalimumab originator and 206 (27%) with ABP 501. Among the biosimilars 60 (29.1%) patients were naïve to adalimumab treatment. The overall 6-month retentions rate was 93.1%. The 6-month retention rate for adalimumab and ABP 501 were 93.3% and 91.2% respectively, without significant differences between the groups (p=0.541). Patients switching from originator to biosimilar showed and overall higher treatment survival when compared to naive (6-month retention rate 95% vs 90-4%), although it was not significant (p=0.179).

Conclusion:

In our retrospective study adalimumab originator and its biosimilar ABP 501 showed the same effectiveness. Patients switching from originator to biosimilar showed an higher retention rate when compared to naive.

OP0063 QUANTITATIVE COMPUTED TOMOGRAPHY PREDICTS 10-YEAR MORTALITY IN INTERSTITIAL LUNG DISEASE RELATED TO SYSTEMIC SCLEROSIS

Background:

Interstitial lung disease (ILD) is the main cause of death in Systemic Sclerosis (SSc). Chest CT is the gold standard in detecting ILD although it is not easy to understand its prognostic value. ILD qualitative assessment is almost worthless. Goh et al. semi quantitative score of ILD extent is related to mortality risk but it is burdened by relevant inter/intra-readers variability. An operator independent algorithm based on voxel-wise analysis proved to identify SSc patients with an increased risk of mortality according to prediction models.

Objectives:

To verify if quantitative analysis of chest CT (QCT) predict 10 years-mortality in SSc patients.

Methods:

SSc patients with availability of a chest CT were enrolled in 13 different centers. The CT voxel-wise analysis with a free software (www.horosproject.com) provided QCT indexes: kurtosis, skewness, mean lung attenuation and standard deviation. Patients characteristics, autoimmune profile and pulmonary function test were collected. The follow-up interval lasted from the date of chest CT to the one of the last visit or death. Each QCT index cutoff, established in a previous study (1), clustered patients in two groups. Kaplan-Meier analysis estimated and compared survival in the above mentioned groups. p < 0.05 was considered statistically significant.

Results:

Five hundred sixty three SSc patients were enrolled (35938 patient-months); 52.4% had ILD detectable at CT scan. For each QCT index cutoff the cohort was split in two subgroups without differences in terms of sex, age, disease duration, autoimmune profile. All QCT indexes’ cutoff selected subgroups with statistically different survival rate (e.g in Figure 1).

Figure 1

Conclusion:

QCT can arise as the new gold standard in identifying SSc patients with poor prognosis. The real possibility to stratify SSc subjects according mortality risk will have a pivotal role in ILD treatment decisional process with the incoming anti-fibrotic drugs.

FRI0499 ACROMEGALY ARTROPATHY: IS THERE SOMETHING MORE BEHIND THE PAIN? A CROSS-SECTIONAL STUDY TO EVALUATE RHEUMATIC DISEASE IN GROWTH HORMONE SECRETING TUMOR PATIENTS

Background:

Acromegaly is a rare disease with a remarkable impact on patients, both in terms of life expectancy and quality of life. Osteo-articular complications are one of the most frequently reported bothers. The “acromegaly artropathy” characterizes more than 70% of patients at diagnosis. Artropathy affects both spine and peripheral joints. A recent prospective study documented progression of acromegalic arthropathy identified as a worsening of osteophytes and joint space narrowing in 72–74% of patients despite long-term biochemical control. In addiction the Literature has occasionally reported cases of simultaneous presence of rheumatic diseases (rheumatoid arthritis, polymyalgia rheumatica, undifferentiated connective tissue diseases) and acromegaly and in all these cases the treatment has been delayed, because of wrong symptoms attribution to acromegaly artropathy.

Objectives:

The primary goal of the study is to better characterize joint pain in acromegaly patients and to evaluate the prevalence of rheumatic disease in growth hormone (GH) secreting pituitary tumor patients.

Methods:

We enrolled 20 acromegaly subjects (AS) and 20 control subjects (CS). In each subject immunological pattern (rheumatoid factor – RF; antinuclear antibodies - ANA, ENA; anti-citrullinated protein antibodies - ACPA; erythrocyte sedimentation rate – ESR) has been evaluated; they, also, underwent bilateral joint ultrasound of hands and wrists and nail capillaroscopy. The Chi square test and the Fisher’s exact test were used to evaluate the association between binary variables, while the Spearman’s test to evaluate the correlation of continuous ones. A multiple or logistic regression model was calculated in order to define the association between the capillaroscopic alterations and other detected variables.

Results:

Articular pain emerged as significantly more frequent in AS (p = 0.0269). No statistically significant differences are detected regarding immunological pattern. ANA and ENA screening resulted positive in 10% in AS and in 5% in CS. No IgA ACPA were detected in AS or CS, while IgG ACPA were positive only in one AS subject. No significant differences were detected between IgM and IgG RFin the two groups (AS 5% and CS 0%). Three fold higher IgG FR in AS compared to CS were detected. ESR levels were significantly higher than CS (p = 0.0405), as well as increased power doppler (PWD) articular uptake (AS 30% vs CS 5% p 0.081). The capillaroscopic evaluation showed a significant difference in almost each parameter that has been evaluated (logistic regression: number of enlargement p 0.004, hemorragies p 0.01 and capillaries p 0.001), showing a moderate-severe microangiopathy in AS. Interestingly, analyzing only the acromegaly cohort, we noticed higher GH levels at the enrollment in patients which developed capillary enlargements (GH: 0.95 ng/ml IQ 0,6-1,6) compared to other ones (GH: 0.55 ng/ml IQ 0.4-0.7; p = 0.08) and a significant lower number of hemorrhages (p = 0.02) in patients treated with GH antagonist pegvisomant.

Conclusion:

Our results demonstrated that joint damage in acromegaly does not seem to have an autoimmune etiology. Therefore, articular damage is mechanical and increased ESR and PWD alterations seems to confirm the presence of an inflammatory component. In addition, acromegaly is characterized by a microvascular pattern of moderate-severe microangiopathy, without correlation to IGF-I, but GH levels. Although requiring further confirmatory studies, our preliminary results seem to indicate how the capillaroscopic examination could be useful to detect earlier microangiopathy and to identify patients with a greater risk of macroangiopathy development..

The Italian Society of Rheumatology clinical practice guidelines for the management of polymyalgia rheumatica

OBJECTIVE

to provide evidence-based up-to-date recommendations for the management of patients with a definite diagnosis of polymyalgia rheumatica (PMR).

METHODS

A systematic literature review was performed to find the existing clinical practice guidelines (CPGs) on PMR and the framework of the Guidelines International Network Adaptation Working Group was used to appraise (AGREE II), synthesize, and customize the recommendations according to the needs of the Italian healthcare context. Rheumatologists on behalf of the Italian Society of Rheumatology (SIR) and from the SIR Epidemiology Unit joined the working group and identified the key health questions on PMR to guide the systematic literature review. Physicians, including general practitioners and specialists, and health professionals who manage PMR in the clinical practice were the target audience. The final recommendations were rated externally by a multi-disciplinary and multi-professional group of stakeholders.

RESULTS

From the systematic search in databases (Medline, Embase) and grey literature, 3 CPGs were identified and appraised by two independent raters. Combining the statements and the evidence from these CPGs, 9 recommendations were developed by endorsement or adaptation in response to the initial key health questions. The quality of evidence was graded and the working group discussed the final recommendations in view of their implementation in the Italian healthcare context.

CONCLUSIONS

In absence of national guidelines so far, these recommendations are the first to provide guidance for the management of patients with a diagnosis of PMR in Italy and they are expected to ensure the best evidence-based clinical practice for this disease.

Osteoarthritis (OA) is the most common musculoskeletal disease leading to functional decline and loss in quality of life. Knees, hands and hips are frequently affected joints with a relevant clinical and socio-economic burden. An evidence-based approach to OA management is essential in order to improve patients' health and to decrease social burdens. Since new international clinical practice guidelines (CPGs) focused on diagnosis or pharmacological/non-pharmacological treatment have become available in the last ten years, the Italian Society for Rheumatology (SIR) was prompted to revise and customize them for a multidisciplinary audience of specialists involved in the management of OA. The framework of the Guidelines International Network Adaptation Working Group was adopted to identify, appraise (AGREE II), synthesize, and customize the existing CPGs on OA to the needs of the Italian healthcare context. The task force, consisting of rheumatologists from the SIR epidemiology research unit and a committee with experience of OA, identified key health questions to guide a systematic review of published guidelines. The target audience included physicians and health professionals who manage OA. An external panel of stakeholders rated the guidelines. From a systematic search in databases (Pubmed/Medline, Embase) and grey literature, 11 CPGs were selected and appraised by two independent raters. Combining evidence and statements from these CPGs and clinical expertise, 16 guidelines were developed and graded according to the level of evidence. Agreement and potential impact on clinical practice were assessed. These revised guidelines are intended to provide guidance for diagnosis and treatment of OA and to disseminate best evidence-based strategies management of the disease.

The Italian Society of Rheumatology clinical practice guidelines for the diagnosis and management of gout

Gout is a chronic disease with an increased risk of premature death related to comorbidities. Treatment of gout has proved suboptimal and clinical practice guidelines (CPGs) are expected to have a key role in achieving improvement. Since new evidence has become available, the Italian Society for Rheumatology (SIR) has been prompted to update the 2013 recommendations on the diagnosis and management of gout. The framework of the Guidelines International Network Adaptation Working Group was adopted to identify, appraise (AGREE II), synthesize, and customize the existing gout CPGs to the needs of the Italian healthcare context. The task force consisting of rheumatologists from the SIR Epidemiology Unit and a committee with experience on gout identified key health questions to guide a systematic literature review. The target audience includes physicians and health professionals who manage gout in practice, and the target population includes adult patients suspected or diagnosed as having gout. These recommendations were finally rated by an external multi-disciplinary commission. From a systematic search in databases (Medline, Embase) and grey literature, 8 CPGs were selected and appraised by two independent raters. Combining evidence and statements from these CPGs and clinical expertise, 14 recommendations were developed and graded according to the level of evidence. The statements and potential impact on clinical practice were discussed and assessed. These revised recommendations are intended to provide guidance for the diagnosis and the treatment of gout and to disseminate the best evidence-based healthcare for this disease.

The Italian Society for Rheumatology clinical practice guidelines for rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disorder characterised by chronic joint inflammation, leading to functional disability and increased risk of premature death. Clinical practice guidelines (CPGs) are expected to play a key role in improving management of RA, across the different phases of the disease course. Since new evidence has become available, the Italian Society for Rheumatology (SIR) has been prompted to update the 2011 recommendations on management of RA. The framework of the Guidelines International Network Adaptation Working Group was adopted to identify, appraise (AGREE II), synthesize, and customize the existing RA CPGs to the Italian healthcare context. The task force consisting of rheumatologists from the SIR Epidemiology Research Unit and a committee with experience in RA identified key health questions to guide a systematic literature review. The target audience includes physicians and health professionals who manage RA in practice, and the target population includes adult patients diagnosed as having RA. An external multi-disciplinary committee rated the final version of the CPGs. From the systematic search in databases (Medline, Embase) and grey literature, 6 CPGs were selected and appraised by two independent raters. Combining evidence and statements from these CPGs and clinical expertise, 8 (Management) +6 (Safety) recommendations were developed and graded according to the level of evidence. The statements and potential impact on clinical practice were discussed and assessed. These revised recommendations are intended to provide guidance for the management of RA and to disseminate the best evidence-based clinical practices for this disease.

Overview on surgical management of papillary thyroid microcarcinoma

Particular interest is now being given to the best treatment of papillary thyroid microcarcinoma (PTMC) due to its significantly increased incidence. PTMC typically shows indolent organic behavior but, in a low percentage of cases, it can express a relative aggressive behavior. Several risk factors have been shown to negatively influence the rate of regional recurrences and metastases such as tumor diameter, Romaage, sex, multifocality, capsular invasion, extracellular diffusion, lymph node metastases, histological variants, mutated Braf and incidentality. The identification of patients with aggressive PTMCs among the majority with low risk lesions is very important to plan an adequate clinical management, thus the most appropriate surgical treatment. The latter includes thyroid lobectomy and total thyroidectomy with central compartment lymphadenectomy, though several studies did not show statistically significant differences in terms of recurrence and mortality rates between the two techniques. At last, it seems crucial to better define those biological features able to improve selection making process of patients with PTMCs aiming to reserve more radical surgery to those patients carrying more aggressive clinicopathologic features and worse prognosis.

Impact of image guidance on toxicity and tumour outcome in moderately hypofractionated external-beam radiotherapy for prostate cancer

To report toxicity and efficacy outcome of moderately hypofractionated image-guided external-beam radiotherapy in a large series of patients treated for prostate cancer (PCa). Between 10/2006 and 12/2015, 572 T1-T3N0M0 PCa patients received 70.2 Gy in 26 fractions at 2.7 Gy/fraction: 344 patients (60%) with three-dimensional conformal radiotherapy (3D-CRT) and 228 (40%) with intensity-modulated radiotherapy (IMRT). Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria and Houston definition (nadir + 2) were used for toxicity and biochemical failure evaluation, respectively. Median age was 74 years (interquartile range 69-77). Compared with 3D-CRT, in IMRT group more high-risk patients (29% vs 18%; P = 0.002) and more high-volume target (75% vs 60%; P < 0.001) were included. Acute gastro-intestinal (GI) toxicity G > 1 were registered in 8% and in 11% IMRT and 3D-CRT patients, respectively, whereas late GI G > 1 were observed in 2% and 16% IMRT and 3D-CRT patients, respectively. Acute genito-urinary (GU) toxicity G > 1 were registered in 26% and 40% IMRT and 3D-CRT patients, respectively, whereas late GU G > 1 occurred in 5% IMRT and 15% 3D-CRT patients. Multivariate proportional hazard Cox models confirmed significantly greater risk of late toxicity with 3D-CRT compared to IMRT for GU > 1 (P = 0.004) and for GI > 1 (P < 0.001). With a median 4-year follow-up, overall survival (OS), clinical progression-free survival (cPFS) and biochemical PFS (bPFS) for the whole series were 91%, 92% and 91%, respectively. cPFS and bPFS were significantly different by risk groups. Multivariate Cox models for bPFS and cPFS showed no difference between irradiation techniques and a significant impact of risk group and initial PSA. Moderately hypofractionated radiotherapy is a viable treatment option for localized PCa with excellent tumour control and satisfactory toxicity profile. IMRT seems associated with a reduction in toxicity, whereas tumour control was equal between IMRT and 3D-CRT patients and depended mainly on the risk category.

Induction TPF followed by concomitant treatment versus concomitant treatment alone in locally advanced head and neck cancer. A phase II-III trial

Background

Platinum-based chemoradiation (CCRT) is the standard treatment for Locally Advanced Head and Neck Squamous-Cell Carcinoma (LAHNSCC). Cetuximab/RT (CET/RT) is an alternative treatment option to CCRT. The efficacy of induction chemotherapy (IC) followed by chemoradiation compared to chemoradiation alone has not been demonstrated in randomized clinical trials. The goals of this phase II-III trial were to assess: (i) the overall survival (OS) of IC versus no-induction (no-IC) and (ii) the Grade 3-4 in-field mucosal toxicity of CCRT versus CET/RT. The present paper focuses on the analysis of efficacy.

Materials and methods

Patients with LAHNSCC were randomized to receive concomitant treatment alone [CCRT (Arm A1) or CET/RT (Arm A2)], or three cycles of induction docetaxel/cisplatin/5 fluorouracil (TPF) followed by CCRT (Arm B1) or followed by CET/RT (Arm B2). The superiority hypothesis of OS comparison of IC versus no-IC (Arms B1 + B2 versus A1 + A2) required 204 deaths to detect an absolute 3-year OS difference of 12% (HR 0.675, with 80% power at two-sided 5% significance level).

Results

414 out of 421 patients were finally analyzed: 206 in the IC and 208 in the no-IC arm. Six patients were excluded because of major violation and one because of metastatic disease at diagnosis. With a median follow-up of 44.8 months, OS was significantly higher in the IC arm (HR 0.74; 95% CI 0.56-0.97; P = 0.031). Complete Responses (P = 0.0028), Progression Free Survival (P = 0.013) and the Loco-regional Control (P = 0.036) were also significantly higher in the IC arm. Compliance to concomitant treatments was not affected by induction TPF.

Conclusions

IC followed by concomitant treatment improved the outcome of patients with LAHNSCC without compromising compliance to the concomitant treatments. The degree of the benefit of IC could be different according to the type of the subsequent concomitant strategy.

Neuromuscular taping enhances hand function in patients with systemic sclerosis: a pilot study

Hand functioning is often impaired in patients with Systemic sclerosis. Neuromuscular Taping is a novel application of tape able to improve functioning. The aim of this study was to evaluate the possible role of this application in the hand functionality of patients with Systemic sclerosis. Women with a diagnosis of SSc has been recruited and evaluated using different scales before and immediately after NMT application and after one, three and six months. Fifty-three women has been evaluated and Cochin Hand Functional Disability scale, Hand Mobility in Sclerodermia, Modified Rodnan Skin Score and Dreiser Algo - Functional Index scores showed statistical significant differences during all the period; moreover a reduction of pain and Raynaud Phenomenon's and an improvement of finger flexion has been observed. Application of NMT in patients with Systemic sclerosis have showed beneficial effect and future studies are needed to confirm these results.

Th-17 cytokines and interstitial lung involvement in systemic sclerosis

The two phenotypes of both limited and diffuse systemic sclerosis (SSc) have different forms of pulmonary involvement: pulmonary arterial hypertension (limited phenotype) or interstitial lung disease (ILD) (diffuse phenotype). We aimed to investigate whether Th17-related cytokines, as measured in exhaled breath condensate (EBC) and in serum were connected to ILD in diffuse SSc patients. We found that for both limited and diffuse SSc, the EBC levels of all cytokines and most of the cytokine serum levels were significantly higher in patients than in controls, while, the EBC levels of Th-17 cytokines and the serum levels of IL-10 and TNF-α were significantly higher in diffuse than in limited SSc. Moreover, the thoracic CT-scan score of ILD was significantly associated with the EBC levels of IL-1 beta and with the serum IL-23, TNF-α and IL-10 levels, whereas lung carbon monoxide diffusing capacity was negatively related to the EBC levels of IL-1 beta, IL-17 and serum IL-10. Serum IL-23 was also inversely correlated with vital capacity. In conclusion, in diffuse SSc patients our results show a clear link between Th-17 cytokines measured both in EBC and in serum with interstitial lung involvement. This highlights how important it is to target Th-17 cytokines when developing new treatments for lung fibrosis.
