RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

The production of pasture in Ethiopia was simulated by means of a dynamic model. Most of the country is characterized by a tropical monsoon climate with mild temperatures and precipitation mainly concentrated in the June-September period (main rainy season). The production model is driven by solar radiation and takes into account limitations due to relocation, maintenance respiration, conversion to final dry matter, temperature, water stress, and nutrients availability. The model also considers the senescence of grassland which strongly limits the nutritional value of grasses for livestock. The simulation for the 1982-2009 period, performed on gridded daily time series of rainfall and maximum and minimum temperature with a resolution of 0.5°, provided results comparable with values reported in literature. Yearly mean yield in Ethiopia ranged between 1.8 metric ton per hectare (t ha-1) (2002) and 2.6 t ha-1 (1989) of dry matter with values above 2.5 t ha-1 attained in 1983, 1985, 1989, and 2008. The Ethiopian territory has been subdivided in 1494 cells and a frequency distribution of the per-cell yearly mean pasture production has been obtained. This distribution ranges from 0 to 7 t ha-1 and it shows a right skewed distribution and a modal class between 1.5-2 t ha-1. Simulation carried out on long time series for this peculiar tropical environment give rise to as lot of results relevant by the agroecological point of view on space variability of pasture production, main limiting factors (solar radiation, precipitation, temperature), and relevant meteo-climatic cycles affecting pasture production (seasonal and inter yearly variability, ENSO). These results are useful to establish an agro-ecological zoning of the Ethiopian territory.

RESUMEN

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. CLINICAL TRIAL NUMBER: NCT01086826, www.clinicaltrials.gov.

RESUMEN

The objective of this study was to evaluate the efficacy of the endothelin receptor antagonist, bosentan, in patients with Raynaud's phenomenon secondary to systemic sclerosis never treated with prostanoids and without digital ulcers. The study design is a preliminary, prospective open label trial. The patients recruited took one 62.5 mg dose of bosentan twice daily for 4 weeks, followed by 125 mg twice daily for 24 weeks. Of the 10 patients recruited, all completed the study. The reduction in Raynaud's phenomenon attacks at week 24 from the baseline was statistically significant (Δ-1.3, P=0.0126). The Raynaud's condition score showed a statistically significant improvement (Δ-1.4, P=0.0279), as did the visual analog pain scale (Δ-1.5, P=0.0016) at the 24th week. Bosentan appears to be effective and may be a valid alternative for the treatment of severe secondary Raynaud's phenomenon for patients where prostanoids therapy is contraindicated or refused.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Genetic heterogeneity in drug-metabolizing enzyme/transporter (DMET) genes affects specific drug-related cancer phenotypes. To investigate the relationships between genetic variation and response to treatment in acute myeloid leukemia (AML), we genotyped 1931 variants on DMET genes in 94 CD33-positive AML patients enrolled in a phase III multicenter clinical trial combining Gemtuzumab-Ozogamicin (GO) with Fludarabine-Cytarabine-Idarubicin (FLAI) regimen, with the DMET Plus platform. Two ADH1A variants showed statistically significant differences (odds ratio (OR)=5.68, P=0.0006; OR=5.35, P=0.0009) in allele frequencies between patients in complete/partial remission and patients without response, two substitutions on CYP2E1 (OR=0.13, P=0.001; OR=0.09, P=0.003) and one on SLCO1B1 (OR=4.68, P=0.002) were found to differently influence liver toxicity, and two nucleotide changes on SULTB1 and SLC22A12 genes correlated with response to GO (OR=0.24, P=0.0009; OR=2.75, P=0.0029). Genetic variants were thus found for the first time to be potentially associated with differential response and toxicity in AML patients treated with a combination of GO-FLAI regimen.

RESUMEN

BACKGROUND: Kidney diseases, which have a prevalence of 3% in women of childbearing age, are increasingly encountered in pregnancy. Glomerulonephritis may develop or flare up in pregnancy, and a differential diagnosis with pre-eclampsia may be impossible on clinical grounds. Use of kidney biopsy is controversial, but a systematic review has not been carried out to date. OBJECTIVES: To review the literature on kidney biopsy in pregnancy, with a focus on indications, risks and timing. SEARCH STRATEGY: Medline, Embase, CHINAL and the Cochrane Library were searched in September 2012, with 'pregnancy' and 'kidney biopsy' used as MESH and free terms, for the period 1980-2012. Results were filtered for 'human' if this option was available. SELECTION CRITERIA: Biopsies during pregnancy and within 2 months after delivery. Case reports (fewer than five cases) and kidney grafts were excluded. Paper selection was performed in duplicate. DATA COLLECTION AND ANALYSIS: Data were extracted in duplicate. The high heterogeneity in study design necessitated that the review be narrative, except for data on adverse events, which were analysed with regard to the timing of kidney biopsy. MAIN RESULTS: Of 949 references, 39 were selected, providing data on 243 biopsies in pregnancy and 1236 after delivery (timing was unclear in 106 women). The main aims of the studies were to define morphology in pre-eclampsia (23 studies), to carry out a risk-benefit analysis of kidney biopsy (11 studies), and to investigate pregnancy-related acute kidney injury (five studies). Four cases of major bleeding complications occurred at 23-26 weeks of gestation. Relevant complications were observed in 7% of women during pregnancy and 1% after delivery (P = 0.001). Kidney biopsy performed for the diagnosis of glomerulonephritis or pre-eclampsia led to therapeutic changes in 66% of cases. AUTHORS' CONCLUSIONS: The evidence on kidney biopsy in pregnancy is heterogeneous, but a significantly higher risk of complications (relative to postpartum biopsy) was found, with a possible peak at around 25 gestational weeks.

RESUMEN

Atmospheric variables play a fundamental role in driving man-managed ecosystems and more specifically in agro-ecosystems, determining the quantity and quality of crop production. On the other hand, climate variability can be seen as the superimposition of gradual and abrupt changes. This paper is focused on European surface air temperature in the period 1951-2010. Analysis of this dataset identified breakpoints that define two homogeneous sub-periods: 1951-1987 and 1988-2010. Thermal resources for crops were analyzed adopting a "normal heat hours" approach. Computation highlighted a general increase in thermal resources in the European continent for crop groups II and III (C3 and C4 plants adapted to high or moderate temperatures), while a decline of thermal resources for crop group I (cold adapted C3) was highlighted in the Mediterranean area. The climate variability justifies a change in the potential latitudinal limits of different groups of crops, representing a fundamental step for crop adaptation to climate change.

RESUMEN

A survey of HIV coreceptor usage in cerebrospinal fluid (CSF) samples, peripheral blood mononuclear cells (PBMCs), and plasma samples from naïve seropositive patients was conducted. One hundred patients were enrolled in this study. Of the 100 patients, 36 had a primary or recent infection (P-RI), 31 had an early chronic infection (>350 CD4 cells) (ECI), and 33 had a late chronic infection (LCI). All 3 compartments were sampled in a subset of 33 participants, while the remaining 67 patients provided plasma samples and PBMCs only. Seventy-seven patients harbored the R5 virus in plasma samples and had a significantly higher median and percentage of CD4(+) T cells than patients with X4 virus (437 and 281 cells/µl, respectively; P = 0.0086; 20.6% and 18.6%, respectively). The X4 strain was detected more frequently in patients with LCI than in patients with P-RI or ECI (39.3%, 19.4%, and 9.6%, respectively; P = 0.0063). PBMC and plasma tropism was concordant in 90 patients, and 73 had the R5 strain. Among patients with discordant results, 4 had the R5 virus in their plasma and the X4 virus in PBMCs; 6 showed the opposite profile. Plasma, PBMC, and CSF tropism determinations were concordant in 26/33 patients (21 patients had R5, and 5 had X4). The tropism was discordant in 5/33 patients, with the X4 virus in plasma and R5 in CSF; the HIV tropism in PBMCs was X4 in 3 patients. The remaining 2/33 patients had the R5 virus in plasma and PBMCs and the X4 virus in CSF; one of these patients had a P-RI. The discordant tropism in CSF and blood may have implications for chemokine (C-C motif) receptor 5 (CCR5) antagonist use in patients with limited response to antiretroviral therapy (ART) or in responding patients evaluated for simplification of treatment.
