Objective: Fragility fractures (FF) resulting from osteoporosis pose a significant public health challenge in Italy, with considerable socio-health and economic implications. Despite the availability of safe and effective drugs, osteoporosis remains underdiagnosed and undertreated, leaving over 2 million high-risk Italian women without treatment. This paper aims to identify and propose key improvements in the management of osteoporosis, focusing particularly on the critical issues related to the use of anabolic drugs in secondary prevention, according to the current Italian Medicines Agency (AIFA) Note 79., Methods: The Expert Panel, composed of nine recognized Italian experts in rheumatology, analyzed current practices, prescribing criteria, and the most recent literature. Three main reasons for revising the indications on pharmacological treatment of osteoporosis were identified: inadequate treatment of osteoporosis, new evidence regarding frontline placement of anabolics in high-risk conditions, and emerging sequential or combined strategies., Results: The proposed improvements include the adoption of the Derived Fracture Risk Assessment algorithm for accurate fracture risk assessment, revision of AIFA Note 79 to reflect current evidence, improved prescribing appropriateness, broader access to anabolic agents, and the provision of sequential therapies with antiresorptives for teriparatide. These changes aim to enhance patient outcomes, streamline healthcare processes, and address the high percentage of undertreated individuals., Conclusions: This expert opinion emphasizes the importance of the appropriate use of anabolic drugs to reduce FF and associated costs while ensuring the sustainability of the National Health Service. The proposed recommendations are in line with the latest scientific evidence, providing a comprehensive strategy to optimize the management of osteoporosis in Italy.

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.

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.

Autoinflammatory disorders are characterized by spontaneous episodes of systemic inflammation deriving from inherited defects of the innate immune system. Childhood is usually the lifetime involved in most inherited autoinflammatory disorders, but a moderate number of patients may experience disease onset during adulthood. Herein we report our experience in the clinical and genetic approach to the diagnosis of autoinflammatory disorders in regard of the first 500 pediatric and adult patients evaluated during the period 2007-2012 in our Center, due to histories of periodically-recurring inflammatory attacks, giving emphasis to the differences observed according to patients'age and to the most relevant data differentiating child and adult-onset autoinflammatory disorders in the medical literature.

The etiology of autoimmune diseases remains largely unknown. In recent years, besides genetic factors, several studies proposed that the epigenome may hold the key to a better understanding of autoimmunity initiation and perpetuation. More specifically epigenetic regulatory mechanisms comprise DNA methylation, a variety of histone modifications, and microRNA (miRNA) activity, all of which act upon gene and protein expression levels. In particular it is well known that epigenetic mechanisms are important for controlling the pattern of gene expression during development, the cell cycle, and the response to biological or environmental changes. In the present review a description of the most frequent epigenetic deregulations, in particular the role of miRNAs, in rheumatic autoimmune disorders will be investigated.

Systemic autoinflammatory diseases are a group of inherited disorders of the innate immunity characterized by the recurrence of febrile attacks lasting from few hours to few weeks and multi-district inflammation of different severity involving skin, serosal membranes, joints, gastrointestinal tube and central nervous system. The vast majority of these conditions is caused by mutations in genes involved in the control of inflammation and apoptosis mechanisms. The group includes familial Mediterranean fever, mevalonate kinase deficiency syndrome, tumor necrosis factor receptor-associated periodic syndrome, cryopyrin-associated periodic syndromes, hereditary pyogenic and granulomatous disorders. Their diagnostic identification derives from the combination of clinical and biohumoral data, though can be sometimes confirmed by genotype analysis.

Antineutrophil cytoplasmic antibodies (ANCA) are predominantly IgG autoantibodies directed against constituents of primary granules of neutrophils and monocytes lysosomes. Although several antigenic targets have been identified, those ANCA directed to proteinase 3 or myeloperoxidase are clinically relevant, whereas the importance of other ANCA remains unknown. Both are strongly associated with small vessel vasculitides, the ANCA-associated vasculitides, which include Wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome, and the localised forms of these diseases (eg, pauci-immune necrotising and crescentic glomerulonephritis). ANCA is a useful serological test to assist in diagnosis of small-vessel vasculitides. 85-95% of patients with Wegener's granulomatosis, microscopic polyangiitis, and pauci-immune necrotising and crescentic glomerulonephritis have serum ANCA. ANCA directed to either proteinase 3 or myeloperoxidase are clinically relevant, yet the relevance of other ANCA remains unknown. Besides their diagnostic potential, ANCA might be valuable in disease monitoring. In addition, data seem to confirm the long-disputed pathogenic role of these antibodies. There is increasing evidence that myeloperoxidase-ANCA are directly involved in the pathogenesis of necrotizing vasculitis. This is less clear for proteinase 3-ANCA, markers for Wegener's granulomatosis. With respect to proteinase 3-ANCA, complementary proteinase 3, a peptide translated from the antisense DNA strand of proteinase 3 and homologous to several microbial peptides, may be involved in induction of proteinase 3-antineutrophil cytoplasmic autoantibodies.

The Authors describe a case of generalised heterotopic ossification (HO) complicating the course of a 31 years old male patient, with a history of Hodgkin's lymphoma and a of long staying in an intensive care unit, where he had been placed on artificial coma. The clinical features, as well as radiological findings and therapy, are discussed.

OBJECTIVE: To test the prevalence of anti-neutrophil cytoplasmic antibodies (ANCA) in systemic sclerosis (SSc) and to verify a possible association of ANCA with normotensive renal involvement in SSc. PATIENTS AND METHODS: 51 patients affected by SSc, 35 with diffuse scleroderma (dSSc) and 16 with limited scleroderma (lSSc), were tested for ANCA by indirect immunofluorescence (IIF) on human ethanol and formalin-acetone-fixed granulocytes (before and after DNase treatment), by conventional enzyme linked immuno-sorbent assay (ELISA) and by capture-ELISA. RESULTS: Six out of 51 selected SSc patients had ANCA by IIF (11.7%) and five presented a perinuclear/nuclear atypical ANCA pattern. In all cases we only found anti-proteinase3 (aPR3) antibodies. All ANCA positive patients had diffuse form of SSc (17.1%), all were anti-Scl70 positive (aScl70), five patients had proteinuria, three had microscopic haematuria. All ANCA positive patients were normotensive with normal renin plasma levels, the mean erythrocyte sedimentation rate (ESR) was higher in this group compared to the other SSc patients. CONCLUSIONS: Our study shows that aPR3 is not rare in dSSc. According to the clinical and serological findings and to the recent literature, we can hypothesise that when ANCA are found in SSc, an overlapping of scleroderma with systemic necrotizing vasculitis should be suspected.
