Expert opinion on the management of patients with osteoporosis with anabolic drugs in Italy.

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.

Persistence of bDMARD therapy in Rheumatoid Arthritis after first-line TNF-inhibitor failure: the RECORD study of the Italian Society for Rheumatology.

OBJECTIVE: The optimal choice of a second biological disease-modifying anti-rheumatic drug (bDMARD) after failure with first line tumour necrosis factor inhibitor (TNFi) represents a critical therapeutic challenge. This study aims to evaluate the persistence with treatment using second line bDMARDs with different mechanisms of action in rheumatoid arthritis (RA) patients with inadequate response to first line TNFi. METHOD: A retrospective cohort study on administrative healthcare databases was conducted. We analysed the relationship between different bDMARDs and persistence with treatment in RA patients who started second line bDMARD therapy according to two different strategies: cycling (second TNFi) or switching [change in mechanism of action: abatacept (ABA), tocilizumab (TCZ), and rituximab (RTX)] with or without concomitant conventional synthetic (cs) DMARDs. RESULTS: The cohort comprised 1434 patients. The mean age was 53.8 years and 1142 (79.6%) were women. Among second line bDMARDs, 969 patients (67.6%) started TNFi, 204 (14.2%) ABA, 145 (10.1%) RTX, and 116 (8.1%) TCZ. A bDMARD was prescribed as monotherapy in 359 patients (25.0%). The switching strategy showed a lower overall discontinuation rate [hazard ratio (HR) 0.72], while switching compared to cycling showed significantly better survival for ABA (HR 0.61) and RTX (HR 0.76), but no significant difference for TCZ (HR 0.82). A lower impact of better drug survival in the switching strategy occurred in patients with concurrent methotrexate. CONCLUSIONS: Among RA patients failing a first TNFi, switching is associated with marginally better persistence, in particular for ABA and RTX, with only marginal differences in patients on concurrent csDMARDs.

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.

Cytomegalovirus infection in Systemic Lupus Erythematosus: report of four cases challenging the management of the disease, and literature review.

Cytomegalovirus (CMV) is particularly dangerous in systemic lupus erythematosus (SLE), being a problem both for the differential diagnosis with disease flare and for the management of SLE flare with immunosuppressive drugs. We report on four cases of SLE with concomitant CMV infection, having some common clinical and laboratory characteristics. Our data suggest that lupus patients presenting with symptoms such as fever, diarrhea, and respiratory symptoms, alone or in combination, and laboratory evidence of leukopenia, elevated transaminases, and hyponatremia, especially in the setting of recent immunosuppressive treatments, should be screened for CMV.

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.

Early Lupus Project: one-year follow-up of an Italian cohort of patients with systemic lupus erythematosus of recent onset.

Objective To describe the clinical and serological features of a prospectively followed cohort of early diagnosed systemic lupus erythematosus (SLE) patients during a one-year follow-up period. Methods SLE patients with disease duration less than 12 months were consecutively enrolled in a multicentre, prospective study. At study entry and then every 6 months, a large panel of data was recorded. Results Of 260 patients enrolled, 185 had at least 12 months of follow-up; of these, 84.3% were female, 92.4% were Caucasians. Mean diagnostic delay was about 20 months; higher values of European Consensus Lupus Activity Measurement (ECLAM) and of organs/systems involved were both associated with shorter diagnostic delay. Clinical and serological parameters improved after study entry. However, patients' quality of life deteriorated and cardiovascular risk factors significantly increased. About one-third of patients with active disease at study entry went into remission (ECLAM = 0). Negative predictors for remission were: oral ulcers, arthritis, low C4, anti-SSB (Ro) antibodies and therapy with mycophenolate. There was a widespread use of glucocorticoids both at baseline and during follow-up. Conclusion Clinical symptoms and serological parameters improve during the first period after diagnosis. However, patients' quality of life deteriorates. The widespread use of glucocorticoids is probably the reason for the early significant increase of some cardiovascular risk factors.

Early Lupus Project - A multicentre Italian study on systemic lupus erythematosus of recent onset.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease with a high degree of variability at onset that is problematic for a correct and prompt diagnosis. We undertook this project with the purpose of collecting an inception cohort of Italian patients with recent-onset SLE, in order to obtain information on the main clinical and serological characteristics at the beginning of the disease. In this first report we describe the characteristics of this cohort at study entry. METHODS: All patients with a diagnosis of SLE (1997 ACR criteria) and a disease duration less than 12 months were consecutively enrolled between 1 January 2012 and 31 December 2013 in a multicentre prospective study. Information on clinical and serological characteristics at study entry and then every six months was collected into a specific electronic database. Statistical analysis was performed by means of the Openstat program. RESULTS: Among 122 patients enrolled (103 F) 94.3% were Caucasians. Mean age (SD) of patients at study entry was 37.3 (14.3) years, mean age at disease onset was 34.8 (14.3) years, mean age at diagnosis was 36.9 (14.3) years, and mean disease duration was 2.9 (3.9) months. The frequency of the manifestations included in the 1997 ACR criteria was as follows: ANA 97.5%, immunologic disorders (anti-dsDNA, anti-Sm, antiphospholipid antibodies) 85.2%, arthritis 61.8%, haematologic disorders 55.7%, malar rash 31.1%, photosensitivity 29.5%, serositis 27%, renal disorders 27%, oral/nasal ulcers 11.5%, neurologic disorders 8.2%, and discoid rash 5.7%. The cumulative frequency of mucocutaneous symptoms was 77.8%. At enrolment, autoantibody frequency was: ANA 100%, anti-dsDNA 83.6%, anti-SSA 28%, anticardiolipin 24.5%, anti-nRNP 20.4%, anti-beta2GPI 17.2%, lupus anticoagulant 16.3%, anti-Sm 16%, and anti-SSB 13.1%. CONCLUSIONS: In this paper we describe the main clinical and serological characteristics of an Italian inception cohort of patients with recent-onset SLE. At disease onset, mucocutaneous manifestations, arthritis and haematologic manifestations were the most frequent symptoms; ANA, anti-dsDNA and complement reduction were the most frequent laboratory findings. Our data confirm that the diagnosis of SLE is a challenging one, and that SLE is a severe disease even at onset, since the majority of patients require at least a hospitalization before the diagnosis.

Childhood versus adulthood-onset autoinflammatory disorders: myths and truths intertwined.

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.

MicroRNAs in autoimmune rheumatic diseases.

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.

Validation of a diagnostic score for the diagnosis of autoinflammatory diseases in adults.

Most autoinflammatory disorders typically come out in the pediatric population, although a limited number of patients may experience disease onset during adulthood. To date, a late disease onset has been described only in familial Mediterranean fever, caused by mutations in the MEFV gene, and in tumor necrosis factor receptor-associated periodic syndrome, caused by mutations in the TNFRSF1A gene. The relative rarity and lack of information on adult-onset autoinflammatory diseases make it likely that mutations will be found in an even smaller percentage of cases. With the aim of improving the genetic diagnosis in adults with suspected autoinflammatory disorders, we recently identified a set of variables related to the probability of detecting gene mutations in MEFV and TNFRSF1A and, in addition, we have also proposed a diagnostic score for identifying those patients at high risk of carrying mutations in these genes. In the present study we evaluated the preliminary score sensitivity and specificity on a wider number of patients in order to validate the goodness of fit of the model. Two hundred and nineteen consecutive patients with a clinical history of periodic fever attacks were screened for mutations in MEFV and TNFRSF1A genes; detailed information about family/personal history and clinical manifestations were also collected. For the validation of the score we considered data both from the 110 patients used to build the preliminary diagnostic score and from the additional 219 patients enrolled in the present study, for a total number of 329 patients. Early age at disease onset, positive family history for recurrent fever episodes, thoracic pain, abdominal pain and skin rash, which are the variables that had previously been shown to be significantly associated with a positive genetic test result (12), were used for validation. On univariate analysis the associations with a positive genetic test were: age at onset (odds ratio [OR] 0.43, p=0.003), positive family history for recurrent fever episodes (OR 5.81, p<0.001), thoracic pain (OR 3.17, p<0.001), abdominal pain (OR 3.80, p<0.001) and skin rash (OR 1.58, p=0.103). The diagnostic score was calculated using the linear combination of the estimated coefficients of the logistic multivariate model (cut-off equals to 0.24) revealing good sensitivity (0.778) and good specificity (0.718). In conclusion, our score may serve in the diagnostic evaluation of adult patients presenting with recurrent fever episodes suspected of having an autoinflammatory disorder, helping identify the few subjects among them who may be carriers of mutations in MEFV and TNFRSF1A genes.

[The laboratory approach in the diagnosis of systemic autoinflammatory diseases]. / L'approccio laboratoristico nella diagnostica delle malattie autoinfiammatorie sistemiche.

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.

A study of Adenosine-Deaminase genetic polymorphism in rheumatoid arthritis.

Recent investigations suggest that Adenosine Deaminase (ADA) could play a role in susceptibility to rheumatoid arthritis (RA). The purpose of our study is to investigate the possible role of genetic variability of ADA in the susceptibility to RA. We studied three intragenic ADA polymorphisms, ADA1, ADA2 and ADA6, in a sample of 91 subjects with RA and in 246 healthy subjects from the same Caucasian population and compared genotype and pairwise haplotype distributions between cases and controls. No statistically significant differences between RA and controls are observed for ADA genotypes. A border line difference for ADA1-ADA2 haplotype distribution is observed due to a decreased proportion of ADA1 *2/ADA2 *2 haplotype in RA compared to controls. Our data indicate a border line effect of ADA gene polymorphism on susceptibility to RA that need to be confirmed in other clinical settings.

The 10-year follow-up data of the Euro-Lupus Nephritis Trial comparing low-dose and high-dose intravenous cyclophosphamide.

OBJECTIVE: To update the follow-up of the Euro-Lupus Nephritis Trial (ELNT), a randomised prospective trial comparing low-dose (LD) and high-dose (HD) intravenous (IV) cyclophosphamide (CY) followed by azathioprine (AZA) as treatment for proliferative lupus nephritis. PATIENTS AND METHODS: Data for survival and kidney function were prospectively collected during a 10-year period for the 90 patients randomised in the ELNT, except in 6 lost to follow-up. RESULTS: Death, sustained doubling of serum creatinine and end-stage renal disease rates did not differ between the LD and HD group (5/44 (11%) vs 2/46 (4%), 6/44 (14%) vs 5/46 (11%) and 2/44 (5%) vs 4/46 (9%), respectively) nor did mean serum creatinine, 24 h proteinuria and damage score at last follow-up. Most patients in both groups were still treated with glucocorticoids, other immunosuppressant agents and blood pressure lowering drugs. After 10 years of follow-up, the positive predictive value for a good outcome of an early drop in proteinuria in response to initial immunosuppressive therapy was confirmed. CONCLUSION: The data confirm that a LD IVCY regimen followed by AZA-the "Euro-Lupus regimen"-achieves good clinical results in the very long term.

Immunogenetic studies on systemic lupus erythematosus.

Understanding the pathogenesis of systemic lupus erythematosus (SLE) remains a considerable challenge. Multiple abnormalities of both the innate and adaptive immune system have been described and, furthermore, immunological dysfunction precedes clinical presentation by many years. There is a strong genetic basis to SLE, which means that genetic studies can play a key role in furthering our understanding of this disease. Because susceptibility variants are present from birth and are unaffected by the course of the disease, or by its treatment, genetic analysis is, perhaps uniquely, capable of identifying fundamental, causative, disease mechanisms. In this article, we review our SLE immunogenetic studies performed in collaboration with the European Working Party on Systemic Lupus Erythematosus. By considering the results of our research and the recent advances obtained by genome-wide associations' studies, we can begin to understand how dysregulation at a number of key immunological steps may predispose to the development of SLE.

Efficacy and safety of anti-TNF-alpha therapy combined with cyclosporine A in patients with rheumatoid arthritis and concomitant hepatitis C virus infection.

This study further expands our previous observation demonstrating the usefulness of combination therapy of anti-TNF-alpha and cyclosporine A in the treatment of rheumatoid arthritis and concurrent hepatitis C virus infection, as well its efficacy and safety in controlling HCV viremia and liver toxicity. Seven patients were included in the study; transaminase levels remained unchanged, HCV RNA serum levels decreased significantly and DAS 28 significantly improved after twelve month follow-up. No side effects were registered.

[Antineutrophil cytoplasmic antibodies]. / Anticorpi anti-citoplasma dei granulociti neutrofili (ANCA).

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.

Idiopathic recurrent pericarditis refractory to colchicine treatment can reveal tumor necrosis factor receptor-associated periodic syndrome.

Recurrences develop in up to 20-50% of patients with acute pericarditis. Although different causes of recurrent pericarditis have been identified, the etiology remains obscure in most cases which are therefore labelled as idiopathic. Autoinflammatory syndromes include familial Mediterranean fever (FMF), due to mutations in the MEFV gene, and tumor necrosis factor receptor-associated periodic syndrome (TRAPS), due to mutations in the TNFRSF1A gene. Recurrent pericarditis is a common feature of both conditions, but it rarely occurs alone. Colchicine is the standard treatment for FMF, while patients with TRAPS do not respond to colchicine therapy, but are responsive to corticosteroids. Based on the proven efficacy of colchicine in preventing polyserositis in FMF, colchicine has been proposed for the treatment of recurrent pericarditis and is able to decrease the recurrence rate. Our aim was to investigate the possible involvement of TNFRSF1A mutations in a group of patients with idiopathic recurrent pericarditis who were refractory to colchicine treatment. Thirty consecutive patients (17 males, 13 females) diagnosed with idiopathic recurrent pericarditis, who were characterized by a poor response to colchicine treatment, were enrolled in the study. Mutations of the TNFRSF1A gene were searched for by amplifying, using polymerase chain reaction (PCR), genomic DNA, and direct sequencing. TNFRSF1A mutations were found in 4 of the 30 patients. None of these 4 patients had a family history of recurrent inflammatory syndromes or history of pericarditis. One of the 4 patients had a novel heterozygous deletion (DeltaY103-R104) and three patients carried a heterozygous low-penetrance R92Q mutation. Our data suggest that TRAPS should be kept in mind in the differential diagnosis of recurrent pericarditis, and mutation analysis of the TNFRSF1A gene should be considered, in addition to MEFV analysis, in patients of Mediterranean origin. A poor response to colchicine treatment and/or a steroid-dependence may be the clue to investigate TNFRSF1A mutations in patients with idiopathic recurrent pericarditis.

Opposed independent effects and epistasis in the complex association of IRF5 to SLE.

Genetic variation in the interferon regulatory factor 5 (IRF5) gene affects systemic lupus erythematosus (SLE) susceptibility. However, association is complex and incompletely defined. We obtained fourteen European sample collections with a total of 1383 SLE patients and 1614 controls to better define the role of the different IRF5 variants. Eleven polymorphisms were studied, including nine tag single nucleotide polymorphisms (SNPs) and two extra functional polymorphisms. Two tag SNPs showed independent and opposed associations: susceptibility (rs10488631, P<10(-17)) and protection (rs729302, P<10(-6)). Haplotype analyses showed that the susceptibility haplotype, identified by the minor allele of rs10488631, can be due to epistasis between three IRF5 functional polymorphisms. These polymorphisms determine increased mRNA expression, a splice variant with a different exon 1 and a longer proline-rich region in exon 6. This result is striking as none of the three polymorphisms had an independent effect on their own. Protection was independent of these polymorphisms and seemed to reside in the 5' side of the gene. In conclusion, our results help to understand the role of the IRF5 locus in SLE susceptibility by clearly separating protection from susceptibility as caused by independent polymorphisms. In addition, we have found evidence for epistasis between known functional polymorphisms for the susceptibility effect.
