Anti-tumor necrosis factor α: originators versus biosimilars, comparison in clinical response assessment in a multicenter cohort of patients with inflammatory arthropathies.

OBJECTIVE: To compare etanercept and adalimumab biosimilars (SB4 and ABP501) and respective bioriginators in terms of safety and efficacy in a real-life contest. METHODS: We consequently enrolled patients affected by rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, treated with SB4, and ABP501, or with corresponding originators, belonging to the main biological prescribing centers in the Lazio region (Italy), from 2017 to 2020. Data were collected at recruitment and after 4, 8, 12, and 24 months of therapy. RESULTS: The multicenter cohort was composed by 455 patients treated with biosimilars [SB4/ABP501 276/179; female/male 307/146; biologic disease-modifying anti-rheumatic drug (b-DMARD) naïve 56%, median age/ interquartile range 55/46-65 years] and 436 treated with originators (etanercept/adalimumab 186/259, female/ male 279/157, b-DMARD naïve 67,2%, median age/interquartile range 53/43-62 years). No differences were found about safety, but the biosimilar group presented more discontinuations due to inefficacy (p<0.001). Female gender, being a smoker, and being b-DMARD naïve were predictive factors of reduced drug survival (p=0.05, p=0.046, p=0.001 respectively). The retention rate at 24 months was 81.1% for bioriginators and 76.5% for biosimilars (median retention time of 20.7 and 18.9 months, respectively) (p=0.002). Patients with remission/low disease activity achievement at 4 months showed a cumulative survival of 90% to biosimilar therapy until 24 months (p=0.001); early adverse reactions instead represented a cause of subsequent drug discontinuation (p=0.001). CONCLUSIONS: Real-life data demonstrated a similar safety profile between biosimilars and originators, but a reduced biosimilar retention rate at 24 months. Biosimilars could be considered a valid, safe, and less expensive alternative to originators, allowing access to treatments for a wider patient population.

Duration of symptom relief after intra-articular injection of hyaluronic acid combined with sorbitol (anti-ox-vs) in symptomatic hip osteoarthritis.

The intra-articular administration of hyaluronic acid (HA) in hip osteoarthritis (OA) has been recently increased following the use of ultrasound guidance to perform an accurate delivery of the injected product. Viscosupplementation in hip OA seems to show similar results to those obtained by viscosupplementation in knee OA. However, an unmet need is the duration of symptomatic relief, therefore several new products are proposed to prolong and increase symptomatic effects. Among these, an innovative viscosupplement has been produced from high a concentration of HA combined with a high concentration of sorbitol as a free radical scavenger. The aim of this study is to evaluate the mid-term pain-relief effect of an ultrasound-guided injection of SynolisV-A (ANTI-OX-VS) in patients suffering from symptomatic hip osteoarthritis. Lequesne index, Health Assessment Questionnaire (HAQ), pain reduction, Global Patient Assessment (GPA), Global Medical Assessment (GMA) and reduction in monthly analgesic consumption were assessed during the 12-month follow-up after the injection. A total of 20 patients were enrolled in the study and received one IA US-guided injection of two syringes of ANTI-OX-VS into the target hip. Eleven drop-out patients were registered, of whom 2 were for loss of efficacy at 6 months, 1 for loss of efficacy at 9 months and 8 patients for severe comorbilities. Mean scores of all clinical parameters evaluated at each control visit were significantly different when compared with baseline mean value. No systemic adverse events were observed. Even though the sample size of this study is limited, the results suggest a durable good efficacy of a 4-ml single injection of ANTI-OX-VS in hip OA, at least for the patients who completed the study. A larger number of patients and an RCT are needed to confirm these data, investigating also the predictive factors of clinical response to ANTI-OX-VS.

Psoriatic arthropathy in patients with previous neoplasia: a case series of four patients treated with secukinumab and literature review.

OBJECTIVE: Psoriasis and psoriatic arthritis (PsA) are closely linked to cancer, as supported by the literature. Systemic treatments for psoriasis and PsA, namely non-biological disease-modifying anti-rheumatic drugs (DMARDs), have been associated with increased cancer risk in both conditions. New, more effective biological DMARDs (bDMARDs) do not seem to be associated with higher overall cancer risk compared to those not receiving bDMARDs, opening up possibilities for treating patients with previous or ongoing oncological disease alongside psoriasis and PsA. However, limited literature exists on treating PsA patients with cancer with bDMARDs. This study aims to assess the safety of secukinumab, a bDMARD, in patients with PsA and concurrent cancer. Here, we describe a case series of four patients with PsA treated with bDMARD secukinumab and review the literature on the subject. CASE SERIES: We assessed the laboratory parameters and clinical characteristics of 4 patients with PsA treated with the bDMARD secukinumab and followed up until 30 months. Three patients had oncological disease in remission, while one had active neoplasia. No cancer progression was observed during the treatment of these patients with secukinumab. CONCLUSIONS: In conclusion, our case series, consisting of four PsA patients with concurrent neoplasia treated with secukinumab, showed no evidence of cancer progression and represents the first case of PsA described in the literature treated during active oncological disease, lending support to the safety of secukinumab for the treatment of patients with PsA and concomitant neoplasia.

Approach in glucocorticoid-induced osteoporosis prevention: results from the Italian multicenter observational EGEO study.

Glucocorticoid-induced osteoporosis (GIO) is the most frequent cause of secondary osteoporosis. GIO is linked to glucocorticoids (GC) daily assumption with maximum effect within first months of treatment and decreasing to basal levels as the therapy is discontinued. In Italy, primary prevention of GIO is suggested when GC therapy (prednisone >5 mg/day or equivalent) is taken for longer than 3 months. Lazio GISMO (Italian Group for Study and Diagnosis of Bone Metabolism Diseases) group organized the GC and Osteoporosis Epidemiology study (EGEO) to evaluate physician's approach in preventing GIO. The study involved 19 osteoporosis centers. Patients taking long-term GC therapy were recruited and information collected: medical history and anthropometric data, GC therapy, primary disease, physician's specialty, osteopororosis screening, and pharmacological intervention. The study included 1334 patients. Mean age was 63 ± 13 yr; 243 (18%) patients had a history of falls from standing position in the previous 12 months, 78 (35%) vertebral fractures, 91 (41%) fractures other than vertebral, 27 (12%) femoral fractures, and 27 (12%) multiple sites fractures. The molecules of GC more often prescribed were prednisone and 6-metil prednisolone. One thousand and forty patients (78%) were taking GC for more than 6 months. GC therapy was prescribed more frequently by rheumatologists (62%). Antiosteoporotic drugs for GIO prevention were prescribed in 431 patients (32%). Among the patients, only 27% (360) received calcium and vitamin D supplements, and 39% (319) treated by rheumatologists received anti-resorptive drugs. In conclusion, our data show that in Italy, as already described elsewhere, only a small subpopulation of GC-treated patients was supported by an anti-osteoporotic therapy, indicating the need to further stimulate awareness of both patients and specialists, prescribing GC therapy, to an appropriate and prompt GIO prevention.

Ranking antireabsorptive agents to prevent vertebral fractures in postmenopausal osteoporosis by mixed treatment comparison meta-analysis.

INTRODUCTION: Bisphosphonates are considered as a first-line therapy for the prevention and treatment of osteoporosis, showing in double-blind, randomized, controlled trials a significant reduction of incidence of new vertebral fractures compared to placebo. Recently also, Denosumab has been shown to reduce the appearance of new vertebral fractures by blocking RANK. There are not head to head comparative studies between the above mentioned drugs. Mixed treatment comparison, an extension of traditional meta-analysis, is able to compare simultaneously several drugs across a range producing a synthetic evidence of efficacy and a range of probability as to the best treatment. OBJECTIVES: The aim of this study is to simultaneously compare alendronate, risedronate, ibandronate, zolendronate and denosumab in the prevention of OP vertebral fractures in a Bayesian meta-analysis for assessing indirect comparisons. MATERIALS AND METHODS: A search for randomized controlled trials involving alendronate, risedronate, ibandronate, zolendronate and denosumab was conducted using several databases. Randomized controlled trials (RCTs) with a double blind treatment period of at least 3 years were included. Men and Glucorticoid Induced osteoporosis, RCTs having as primary or secondary endpoints continuous values as body mineral density (BMD) and studies comparing different dosing regimens of the same agent, which are not used in clinical practice, were excluded. Only fully published reports were considered. RESULTS: A total of 9 RCTs were identified providing data on 31,393 participants. Zolendronate had the highest probability (52%) of being the most effective treatment towards placebo, followed by denosumab (46% probability), ibandronate and then alendronate and risedronate against placebo. CONCLUSIONS: Although the mixed treatment comparisons among alendronate, risedronate, ibandronate, zolendronate and denosumab did not show a statistically significant difference, this analysis suggests that zolendronate, compared to placebo, is expected to provide the highest rate of reduction in vertebral fractures affecting osteoporosis affected patients.

Safety of intra-articular hip injection of hyaluronic acid products by ultrasound guidance: an open study from ANTIAGE register.

OBJECTIVE: We developed a standardized technique for ultrasound guided intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. In this article we report the safety of this technique in an extended series of patients. PATIENTS AND METHODS: Patients were injected supine with an anterosuperior approach under ultrasound guidance. The Us probe is applied with a target device for biopsy. RESULTS: The standardised technique was used to inject 1906 patients with 4002 injections of hyaluronan products over a four-year period. The treatment was well tolerated with few, and exclusively local, side effects. CONCLUSIONS: The administration of hyaluronans under ultrasound-guided intra-articular injection is a safe technique for treatment of rheumatic diseases of the hip.

May etanercept and PTH (1-34) association heal erosions in early rheumatoid arthritis? A pilot study.

INTRODUCTION: Rheumatoid arthritis (RA) is characterized by the formation in the joints of an inflammatory tissue, which causes the appearance of localized erosions on the margins of the joints. The molecular mechanism that causes the bone erosion is multifactorial. Inflammatory cytokines imbalance and OPG-RANK-L system are involved. OBJECTIVE OF THE STUDY: The aim of the study is to evaluate the possibility of inducing healing or reduction in the number of erosions in Rheumatoid Arthritis patients treated with anti-TNF-alpha adding Teriparatide (PTH1-34) to standard treatment with anti-TNF. PATIENTS AND METHODS: Twenty adult patients with active RA diagnosed according to American Rheumatism Association (ARA) criteria at least 6 months before study begin were enrolled. Only patients affected by established RA (6 to 18 months from symptoms beginning) were recruited. Eligible patients were randomized to receive a standard dosage of etanercept (50 mg/week) or etanercept at same dosage with an addition of teriparatide (20 mg). Evaluation of eventual healing of arthritic erosions by magnetic resonance imaging was performed at time zero and then at twelve months. The following evaluation was assessed at baseline and after 12 months according to the Outcome Measures in Rheumatology Clinical Trials (OMERACT) definitions: number of erosion and presence or absence of synovitis, effusion and bone oedema. A comparative examination of quantitative and qualitative assessment of each parameter was applied. Plain radiographs of the hands were obtained at baseline and 52 weeks. Radiographs were scored blindly using the van der Heijde modification of the Sharp method. Safety of each treatment was evaluated by means of the adverse events (AES) evaluation and report. RESULTS: There were no significant differences in baseline characteristics between the groups. The study did not achieve its primary endpoint of healing erosions. In the active arm no healing of erosions was found. At 52 weeks, there were no new MRI erosions in two arms. Bone oedema scores were significantly improved at 52 weeks in favour of both treatments versus baseline scores, without inter-groups differences. X-ray patterns were unchanged in all patients of both groups. No new erosions or previous erosions' healing were observed. No AEs were reported. Patients from both groups demonstrated a significant reduction in the DAS 28 scores at 52 weeks (p < 0.005) if compared with baseline values. CONCLUSIONS: These data confirm rapid control of inflammation and MRI damage benefits after Etanercept administration without a significant improvement in MRI findings after concomitant addition of teriparatide. Even though these results could seem to suggest to avoid the simultaneous use of these two drugs to treat RA erosions, further studies might be suggested to asses if sequential adminstration of an anabolic agent such as Teriparatide, after achieving clinical remission, may be able to improve bone damage.

Intradermal therapy (mesotherapy): the lower the better.

BACKGROUND: Intradermal therapy (mesotherapy) is a technique used to inject drugs into the surface layer of the skin. The intradermal micro deposit allows to modulate the kinetics of drugs, slowing down its absorption and prolonging the local mechanism of action. This technique is applied in the treatment of some forms of localized pain when a systemic drug-saving effect is useful, when it is necessary to synergize with other pharmacological or non-pharmacological thera-pies, when other therapies have failed or cannot be used. AIM: The purpose of our study was to evaluate the effect of a mixture with respect to its lower concentration. We also wanted to evaluate the number of sessions needed to reach the therapeutic goal (50% reduction in pain from baseline) in patients with acute or chronic neck pain. METHOD: We analyzed retrospectively data from 62 patients with cervicobrachial pain treated with intradermal drugs. Group A received a mixture of drugs; group B received half the dose of drugs. RESULTS: Patients who received a lower concentration of drugs achieved similar results to those who received a higher dose. The therapeutic goal was achieved on average with 3.5 + 1.7 sessions on a weekly basis (min 1; max 9). Subjects in group A required 4+1.7 treatments (min 1; max 9), while subjects in group B required 3+1.5 treatments (min 1; max 7). CONCLUSIONS: Our study confirms that even a lower dose of drugs can induce a clinically useful result. This study confirms that the useful effect of mesotherapy is only partly due to the pharmacological action. Further randomized prospective studies are needed to standardize the technique in the various pain syndromes, but it is recommended to follow the guidelines of the Italian Society of Mesotherapy to ensure patients receive appropriate treatment.

A new chance to maintain remission induced by anti-TNF agents in rheumatoid arthritis patients: CYnAR study II of a 12-month follow-up.

The advent of biological therapies represented the beginning of a new era in the therapy of Rheumatoid Arthritis (RA), as demonstrated in several studies, but still many questions about their safety, especially in long term use, and correct administration time remain unanswered. Once remission is achieved, the orientation of clinicians regarding the maintenance of biological therapy or the switch to another immunosuppressive therapy is still uncertain. In our previous study 21 patients affected by RA who reached remission by the use of a combined therapy of anti-TNF drugs and methotrexate (MTX) underwent CyA-MTX combination therapy for maintaining remission state and were evaluated during a 6-month follow-up. The present study aims to investigate these data by a longer follow-up (12 months) and on a larger population. Fifty-three RA patients, with a disease duration of less than 3 years and DAS28<3.2 that reached a level of low disease activity within 6-8 months from the beginning of anti-TNF and methotrexate therapy, were enrolled in the study. By the suspension of anti-TNF therapy, patients underwent A-Cyclosporine (2-3 mg/kg/day) and methotrexate (15mg/week) therapy. DAS28, Pain VAS, Erythrosedimentation rate (ESR), C Reactive Protein (CRP) were all tested at time 0 and every 2 months after the interruption of the anti-TNF therapy and the beginning of A-Cyclosporine and methotrexate therapy, as well as liver and kidney profiles. Side effects were also recorded. Of 53 patients, 50 completed the study with a 12-month follow-up. Twenty-one (42%) patients maintained clinical parameters within low disease activity values at 12 months, while 29 (58%) patients showed an increase in DAS28 and other parameters: 16 (32%) patients at the 6-month control, 13 (26%) patients at the 12-month control. Our data show that 42% of the patients undergoing A-Cyclosporin and Methotrexate therapy maintained low disease activity parameters of rheumatoid arthritis, obtained after 6-8 months of anti-TNF therapy. Further studies on larger populations are necessary in order to confirm such results and identify predictor factors for different responses.

Hip viscosupplementation under ultra-sound guidance riduces NSAID consumption in symptomatic hip osteoarthritis patients in a long follow-up. Data from Italian registry.

INTRODUCTION: Non-steroidal anti-inflammatory drugs (NSAIDs) consumption is strictly related to a high gastrointestinal and cardiovascular mortality and morbidity rate. Osteoarthritis Research Society International (OARSI) recommendations in patients with symptomatic hip or knee OA stated that NSAIDs should be used at the lowest effective dose but their long-term use should be avoided if possible. OARSI guidelines for the treatment of the hip OA include the use of viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid. OBJECTIVE: Aim of this multicentric, open and retrospective study is to investigate if NSAID consumption may be reduced by the use of ultrasound-guided intra-articular injection of several hyaluronic acid (HA) products in hip joint administered in patients affected by symptomatic hip OA. MATERIALS AND METHODS: Patients affected by mono or bilateral symptomatic hip OA according to American Rheumatology Association (ARA) criteria, radiological OA graded II-IV (Kellgren and Lawrence) entered the study and were administered with ultrasound-guided intra-articular injection of hyaluronic acid products. As a primary endpoint, consumption of NSAIDs was evaluated by recording the number of days a month (range 0-30) the patient had used NSAID during the previous month, reported at each visit during the 24 months follow-up period. Secondary endpoints included further analysis for subgroups of patients categorized for Lequesne index score, Kellgren-Lawrence score, pain visual analogue scale (VAS) score, ultrasound pattern, age, hyaluronic acid used. RESULTS: 2343 patients entered the study. Regarding primary endpoint, the consumption of NSAIDs was reduced of 48.2% at the third month when compared with baseline values. This sparing effect increased at 12th and 24th month with a reduction respectively of 50% and 61% in comparison to baseline values. These differences were statistically significant. CONCLUSIONS: These data point out that intraarticular hyaluronan preparations provide OA pain relief and reduce NSAIDs consumption in a large cohort of patients for a long period of follow-up. Multiple courses of viscosupplementation (vs) are required to maintain low dose of NSAID consumption over time. NSAIDs consumption is strictly related to an high gastrointestinal and cardiovascular mortality and morbidity rate, instead HA intra-articular treatment is well tolerated and is associated with a low incidence of adverse effects. For these reasons further studies evaluating cost-effectiveness and cost-utility of VS in the management of hip OA are required.

Biologics for psoriatic arthritis: network meta-analysis in review.

OBJECTIVE: A review of network meta-analysis to assess efficacy and safety of biologics for the treatment of psoriatic arthritis (PsA). MATERIALS AND METHODS: A systematic search was conducted on electronic databases to identify Bayesian meta-analysis reporting clinical parameters of efficacy, safety and cost-effectiveness of biologics that are approved for the treatment of PsA patients. RESULTS: We identified 19 studies and included them for review. There is insufficient statistical evidence to demonstrate clear differences in effectiveness between available biologic agents for PsA due to many differences in methods and clinical parameters reported in the studies. Old biologics are reported to be safe. CONCLUSIONS: New molecules approved for the treatment of PsA appear promising treatments but further comparative studies methodologically well-conducted are necessary. It is also necessary to follow strictly international recommendations to conduct NMA to better help physicians and decision-makers in making appropriate decisions.

Can Cyclosporine-A associated to methotrexate maintain remission induced by anti-TNF agents in rheumatoid arthritis patients? (Cynar pilot study).

Biological therapies, such as etanercept, adalimumab and infliximab, have demonstrated good efficacy in inducing rheumatoid arthritis to low disease activity levels. Nevertheless, their cost, as well as the related risk of side effects, especially in long-term therapies, are still high. Furthermore, there is a good deal of evidence proving loss of efficacy of such therapies in the long term, often necessitating the shift from one specific anti-TNF biological treatment to another. There are also other open debates on the amount of time a patient should undergo an anti-TNF therapy, on the possibility of inducing a complete remission in early arthritis and, once remission or low disease activity is obtained, on the possibility of interrupting the anti-TNF-based therapy. In this study we investigated whether A-Cyclosporin and Methotrexate association may be effective in maintaining low disease activity obtained by anti-TNF therapies. Twenty-three rheumatoid arthritis-affected patients, whose diagnosis was made according to ACR criteria, with a disease duration of less than 3 years, and DAS28<3.2 that reached a level of low disease activity within 6-8 months from beginning anti-TNF and Methotrexate therapy, were enrolled in the study. After the suspension of anti-TNF therapy, patients were started on A-Cyclosporine (2-3 mg/kg/day) and Methotrexate (15mg/week) therapy. DAS28, Pain VAS, Erythrosedimentation Rate (ESR), and C Reactive Protein (CRP) were all tested at time 0 and at 6 months, as well as liver and kidney profiles, after the interruption of the anti-TNF therapy and the beginning of A-Cyclosporine and Methotrexate therapy. Side effects were also recorded. Of 23 patients undergoing the A-Cyclosporin and Methotrexate therapy for maintaining low disease activity in rheumatoid arthritis obtained by 6-8 months of anti-TNF therapy, 21 completed the study with a 6 month follow-up. Thirteen patients maintained clinical parameters within low disease activity values, while 8 patients showed an increase in DAS28 and other parameters. Only two patients showed an increase in blood pressure that was diagnosed after two months from the beginning of the A-Cyclosporin and Methotrexate therapy. The reduction in the dosage of A-Cyclosporin from 3mg/kg/day to 2mg/kg/day caused a slow normalization of blood pressure values. Our data seem to suggest that more than half of the patients undergoing A-Cyclosporin and Methotrexate therapy seemed to maintain low disease activity parameters of rheumatoid arthritis, obtained after 6-8 months of anti-TNF therapy. Further studies on larger populations are necessary in order to confirm such results and identify predictor factors for different responses.

A new technical contribution for ultrasound-guided injections of sacro-iliac joints.

INTRODUCTION: Sacroiliac joint (SIJ) represents a difficult location for local therapies, as intra-articular injections may be hard to execute, especially in particular conditions such as chronic inflammatory diseases. However, in selected patients, local therapies may be considered. Some recent studies demonstrated the feasibility of ultrasound (US)-guided injection of SIJ, but still a complete explanation and definition of the technique is needed. MATERIALS AND METHODS: Seven patients, four males and 3 females, affected by mono or bilateral sacroiliitis entered the study. Each patient received 40 mg of acetonide triamcinolone for each SIJ, intra articular (IA) US-guided injection. The technical originality proposed in this study consists in the spinal needle insertion in the middle of the cranial long side of the linear transducer with an orientation of about 10 degrees, determining shorter needle insertion for reaching joint space and consequently probably granting lesser pain and traumatism for patients. RESULTS: A total of 22 injections was performed. The longer follow-up time obtained was 18 months in 3 patients. All patients reached at least a 6 month follow-up. All patients reported an amelioration in pain that lasted for at least 6 months. No systemic adverse events were reported or observed. Complete visualization of SIJ and of needle placement was performed by US imaging, while compound proper injection was also visualized by Color-Doppler US imaging. DISCUSSION: Actually, sacroiliac joint intraarticular injections are often performed under fluoroscopy or Computerized Tomography guidance. Such techniques present several limitations, especially for repeated injections, such as the use of ionizing radiations, the need of a contrast agent and the direct and indirect costs connected. US guidance in IA SIJ injections may represent an easily repeatable imaging technique for needle placement and a precious tool for detecting inflammatory activity of the joint.

A review of network meta-analysis comparing biologics in the treatment of rheumatoid arthritis.

OBJECTIVE: Even though in recent years significant improvements have been made in the management of patients with rheumatoid arthritis due to the introduction of biologic agents, it is still difficult to identify the most effective and safest available treatment. The choice and comparison between biological agents are a challenge, for only limited head-to-head clinical studies are available. The aim of this manuscript is to review the published network meta-analysis (NMA) to gain a better understanding of efficacy and safety of biological agents and small molecules in the management of RA patients. MATERIALS AND METHODS: We used MEDLINE and EMBASE to identify network meta-analyses from 2008 to June 2019 comparing efficacy and safety of licensed biological agents and tsDMARDS at the approved dosages using predefined text words related to the topic. The following scenarios have been investigated: patients not responding to csDMARD (cDMARDs - IR); csDMARD naïve patients; patients not responding to biologics (bDMARDs - IR); patients in biological monotherapy. RESULTS: On the basis of the data present in the literature, we are able to hypothesize some trends of response in terms of efficacy in different subsets of patients, for example patients in monotherapy, bDMARds unresponsive patients, and Methotrexate-naive patients. The differences of the results presented in many works are due to the different inclusion criteria used in the studies, the type of biologics agent used in each study (according to the available molecules in the different years of publication), as well as differences in the methodology of NMA and in the presentation of the data. CONCLUSIONS: We suggest that the next NMA follows the indications suggested by the Professional Society for Health Economics and Outcomes Research (ISPOR) so that the results are comparable and comprehensible.

Mixed panniculitis responding to cyclosporin-A with a 12-month follow-up: a case report.

Panniculitides represent a heterogeneous group of inflammatory diseases involving subcutaneous fat. Subcutaneous fat is normally organized into adipose cells, adipocytes, and septa of connective tissue. The inflammation involving such tissues can be more represented in septa (septal panniculitis) or in lobules (lobular panniculitis) or be equally distributed in both (mixed panniculitis). A bioptical study is necessary in order to discern between different forms. Vascular involvement is also different in such diseases, as it can interest arteries, or veins, or both. Different grades of fat necrosis can also be observed, such as adipocytes without nuclei, lipophagic necrosis, liquefactive fat necrosis, microcystic fat necrosis, ischaemic fat necrosis. Panniculitis can be idiopathic or secondary to other diseases such as systemic sclerosis, rheumatoid arthritis, systemic erithematous lupus and many others. Therapies usually vary on the single patient but the general orientation leads to the use of immunosuppressive drugs such as thalidomide, corticosteroids, cyclosporin-A, hydroxychloroquine and cyclophosphamide. We report a case of a 19-year-old female affected by primary mixed panniculitis, associated with fever and deep asthenia, that resolved in a few weeks and was maintained with oral cyclosporin-A.

The safety of anti-TNF agents in the elderly.

Rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis are commonly thought of as inflammatory diseases that affect younger individuals. Although the initial presentation of these diseases is common in a patients twenties or thirties, they usually persist for the duration of the patients life. In addition, up to one-third of patients with RA have disease onset after 60 years of age. Anti-TNF-a therapies now have well-recognized safety profiles that have been demonstrated in the usual clinical trial populations for these diseases, but such populations under-represent patients > or =65 years of age. This retrospective study aims to determine the safety profiles for etanercept, infliximab and adalimumab in patients of 65 years or more, undergoing anti-TNF treatment for an active inflammatory disease such as rheumatoid arthritis, ankylosing spondylitis or psoriatic arthritis, or skin disease like psoriasis. Our data show that admitting elderly patients into anti-TNF therapeutic regimens is a safe option and that it grants these patients access to the best current therapeutic option, possibly leading to better disease outcome. Quality of life in elderly patients affected by arthritis or psoriasis, often reduced by comorbidities, is as important as quality of life in younger patients. Applying the recommended screening before using biological treatment helps to reduce adverse events related to the therapy, and the application of the same screening in elderly patients seems to lead to comparable results.

Viscosupplementation: a suitable option for hip osteoarthritis in young adults.

INTRODUCTION: Young adult hip osteoarthritis (OA) is a noteworthy problem, although rarer than the elderly form of the disease, causing limitations in social and working activities and prospects. Treatment options are scarce and surgical procedures, frequently necessary, imply the major drawback of revising the prostheses periodically, whereas chronic nonsteroidal anti-inflammatory drugs (NSAID) consumption may provoke side effects. To explore alternative options to both surgery and long-term NSAID use, especially in the case of young patients, viscosupplementation seems to appear as an appropriate tool to relieve pain, ameliorate the function and delay surgery. AIM OF THE STUDY: In this study we tackle the issue of the use of hyaluronic acid (HA) injections in young adults with symptomatic hip OA. RESULTS AND CONCLUSIONS: These data, collected from 78 young patients, show that viscosupplementation is a safe procedure, and may provide significant relief from pain and functional recovery. Larger controlled studies are needed to establish otpimal treatment strategies and clinical factors predictive of treatment response.

Cyclosporine A: good response for patients affected by autoimmune disorders and HCV infection?

INTRODUCTION: In autoimmune disorders (ADs), if Hepatitis C Virus (HCV) is present, immunosuppressive treatment could increase virus replication. Cyclosporine A (CsA), in standard therapeutic doses, has been proven able to inhibit HCV cyclophilin in vitro. Therefore CsA could improve the therapy of HCV patients with ADs. AIM: In these patients, we started an open pilot study to evaluate the safety of 3 mg/kg CsA and the ability to reduce steroid therapy. PATIENTS AND METHODS: Five females and 1 male were recruited; mean age 66 +/- 8 years, mean disease duration 13 +/- 5 years. Three patients are affected by Psoriasic Arthritis, 1 by Rheumatoid Arthritis, 1 by Sjogren Syndrome, and 1 by Myasthenia Gravis. None of them had chronic active hepatitis. HCV genotypes were type 2 (in 3 cases) and type 1 (in 3 cases). Patients were treated with 3 mg/kg of CsA for a period of time ranging from 6 to 12 months. The starting mean dose of prednisone was 12.5 mg/day. Liver function tests were checked monthly and serum HCV-RNA load was checked by RT-PCR before and 2 months into the therapy. RESULTS: The prednisone dose was reduced from 12.5 mg/day to 7.5 mg/day. The aminotransferases levels were unchanged after 6 months. In patients with low HCV-RNA levels before treatment, no modifications of viral load were observed, whereas patients with increased levels at onset showed mild reduction 2 months into the treatment. CONCLUSIONS: Immunosuppressive treatment of ADs patients with HCV infection can be safely provided with the integration of CsA.

Relevance of 99mTc-HYNIC-tir-octreotide scintigraphy in a patient affected by sarcoidosis with lung and joints involvement and secondary Sjogren's syndrome treated with infliximab: case report.

We report the case of a 59 years old woman affected by lung and joint sarcoidosis, secondary Sjogren's syndrome refractory to common disease-modifying antirheumatic drugs (DMARDs) that regressed with infliximab and methotrexate. 99mTc-HYNIC-TOC scintigraphy was useful in diagnosis, choice of treatment and follow-up.
