Objective. The aim of this study was to establish guidelines for the optimization of biologic therapies for health professionals involved in the management of patients with RA, AS and PsA. Methods. Recommendations were established via consensus by a panel of experts in rheumatology and hospital pharmacy, based on analysis of available scientific evidence obtained from four systematic reviews and on the clinical experience of panellists. The Delphi method was used to evaluate these recommendations, both between panellists and among a wider group of rheumatologists. Results. Previous concepts concerning better management of RA, AS and PsA were reviewed and, more specifically, guidelines for the optimization of biologic therapies used to treat these diseases were formulated. Recommendations were made with the aim of establishing a plan for when and how to taper biologic treatment in patients with these diseases. Conclusion. The recommendations established herein aim not only to provide advice on how to improve the risk: benefit ratio and efficiency of such treatments, but also to reduce variability in daily clinical practice in the use of biologic therapies for rheumatic diseases.

- Abstract
Introduction: Tumor-induced osteomalacia (TIO), is a rare acquired paraneoplastic syndrome characterized by defective bone mineralization, caused by the overproduction of fibroblast growth factor 23 (FGF23) by a tumor., Material and Methods: We conducted a systematic review to identify all case reports of TIO, focusing on those associated with mesenchymal tumors. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) consensus, and we included patients with a diagnosis of TIO and histological confirmation of phosphaturic mesenchymal tumors or resolution of the condition after treatment of the tumor. Bibliographical searches were carried out until December 2023 in the Cochrane Library, Medline and Embase, as well as congress abstracts online., Results: We identified 769 articles with 1979 cases reported. Most patients were adults, with a higher incidence on men. Disease duration before diagnosis is a mean of 4.8 years. Most tumors were histologically classified as PMT. Lower limbs were the predominant location. Hypophosphatemia was present in 99.8 % of patients. The FGF23 was elevated at diagnosis in 95.5 %. Resection of the tumor was the treatment of choice in most of patients. After resection, there was a clinical improvement in 97.6 % of cases, and serum phosphorus and FGF23 levels returned to normal ranges in 91.5 % and 81.4 % of the patients, respectively., Conclusion: TIO is usually misdiagnosed with rheumatological or musculoskeletal disorders. The diagnosis should be suspected in patients with hypophosphatemic osteomalacia, and the measurement of serum FGF23 can be useful for diagnosis and management., Competing Interests: None of the authors has conflicts of interest., (© 2024 The Authors.

- Abstract
Background: Delay in diagnosis and therapy in patients with arthritis commonly leads to progressive articular damage. The study aimed to investigate the immunohistochemical reactivity of synovial cytokines associated with inflammation and the bone erosives/neoformatives processes among individuals diagnosed with psoriatic arthritis (PsA), rheumatoid arthritis (RA), osteoarthritis (OA), and radiographic axial spondyloarthritis (r-axSpA), with the intention of identifying potential biomarkers., Methods: Specimens were collected from the inflamed knee joints of patients referred for arthroscopic procedures, and the synovial tissue (ST) was prepared for quantifying protein expression through immunohistochemical analysis (% expressed in Ratio_Area-Intensity) for TGF-β1, IL-17A, Dkk1, BMP2, BMP4, and Wnt5b. The collected data underwent thorough analysis and examination of their predictive capabilities utilising receiver operating characteristic (ROC) curves., Results: Valid synovial tissue samples were acquired from 40 patients for IHC quantification analysis. Initially, these patients had not undergone treatment with biologics. However, after 5 years, 4 out of 13 patients diagnosed with PsA and two out of nine patients diagnosed with RA had commenced biologic treatments. Individuals with early PsA who received subsequent biologic treatment exhibited significantly elevated IHC reactivity in ST for TGF-β1 ( p = 0.015). Additionally, patients with both PsA and RA who underwent biologic therapy displayed increased IHC reactivity for IL-17A ( p = 0.016), TGF-β1 ( p = 0.009), and Dkk1 ( p = 0.042). ROC curve analysis of IHC reactivity for TGF-β1, Dkk1, and IL-17A in the synovial seems to predict future treatment with biologics in the next 5 years with the area under the curve (AUC) of a combined sum of the three values: AUC: 0.828 (95% CI: 0.689-0.968; p 0.005) S 75% E 84.4%., Conclusions: Higher synovial immunohistochemistry reactivity of IL-17A, Dkk1, and TGF-β1 in patients with early psoriatic arthritis and rheumatoid arthritis may serve as potential indicators for predicting the necessity of utilising biologic treatments.

- Abstract
Background: Immune and non-immune cells contribute to the pathology of chronic arthritis, and they can contribute to tissue remodeling and repair as well as disease pathogenesis. The present research aimed to analyze inflammation and bone destruction/regeneration biomarkers in patients with psoriatic arthritis (PsA), rheumatoid arthritis (RA), osteoarthritis (OA), and ankylosing spondylitis (AS)., Methods: Samples were obtained from the inflamed knee of patients with knee arthritis who had been referred for undergoing arthroscopies. The synovial membrane was processed for pathological description, IHC analysis, and quantification of mRNA expression ratio by qRT-PCR. Serum levels of TGF-β1, IL-23, IL-6, IL-17 A, IL-22, Dkk1, Sclerostin, BMP2, BMP4, Wnt1, and Wnt5a were measured by ELISA. All these data were analyzed and compared with the demographic, clinical, blood tests, and radiological characteristics of the patients., Results: The synovial membrane samples were obtained from 42 patients for IHC, extraction, and purification of RNA for synovial mRNA expression analysis, and serum for measuring protein levels from 38 patients. IHC reactivity for TGF-β1 in the synovial tissue was higher in patients with psoriatic arthritis (p 0.036) and was positively correlated with IL-17 A (r = 0.389, p = 0.012), and Dkk1 (r = 0.388, p = 0.012). Gene expression of the IL-17 A was higher in PsA patients (p = 0.018) and was positively correlated with Dkk1 (r = 0.424, p = 0.022) and negatively correlated with BMP2 (r = -0.396, p = 0.033) and BMP4 (r = -0.472, p = 0.010). It was observed that IHC reactivity for TGF-β1 was higher in patients with erosive PsA (p = 0.024)., Conclusions: The IHC reactivity of TGF-β1 in synovial tissue was higher in patients with erosive psoriatic arthritis, and TGF-β1 was in relation to higher levels of gene expression of IL-17 A and Dkk1., (© 2023.

- Abstract
Aim: To assess the experience with health care among patients with type 2 diabetes (T2DM) and to evaluate patients' demographic variables and healthcare-related characteristics which may affect their experience., Methods: A cross-sectional survey was delivered to T2DM adults. Patient experiences were assessed with the 'Instrument for Evaluation of the Experience of Chronic Patients' (IEXPAC) questionnaire, a validated 12-item survey, which describes patient experience within the last 6 months (items 1-11) and hospitalization in the last 3 years (item 12), with possible scores ranging from 0 (worst) to 10 (best experience)., Results: A total of 451 T2DM patients responded to the survey (response rate 72.3%; mean age 69.5 ± 10.1 years, 67.8% men). The mean overall IEXPAC score was 5.92 ± 1.80. Mean scores were higher for productive interactions (7.92 ± 2.15) and self-management (7.08 ± 2.27) than for new relational model (1.72 ± 2.01). Only 32.8% of patients who had been hospitalized in the past 3 years reported having received a follow-up call or visit after discharge. Multivariate analyses identified that regular follow-up by the same physician and follow-up by a nurse were associated with a better patient experience. Continuity of healthcare score was higher only in those patients requiring help from others., Conclusions: The areas of T2DM care which may need to be addressed to ensure better patient experience are use of the Internet, new technologies and social resources for patient information and interaction with healthcare professionals, closer follow-up after hospitalization, and a comprehensive multidisciplinary approach with regular follow-up by the same physician and a nurse., Competing Interests: DOB received payment for lectures including services on speakers’ bureaus from MSD, Sanofi, Novo Nordisk, Lilly.

- Abstract
Background: Giant cell arteritis (GCA) is a vasculitis that affects medium- and large-sized arteries. Temporal artery biopsy is the gold standard for diagnosis. In view of the high demand for temporal biopsies, the purpose of this study is to evaluate the usefulness of Doppler ultrasonography in patients with suspected giant cell arteritis, to determine its sensitivity and specificity as a diagnostic test and to determine whether it would be possible to substitute biopsy for ultrasonography., Materials and Methods: A prospective study was undertaken including 57 patients from February 2015 to July 2016, who have undergone both ultrasonography and temporal biopsy., Results: A total of 57 patients were included, 3of whom died during the follow-up, and a patient was excluded from the study when she refused to have the biopsy. Another 21 patients were diagnosed with GCA by a rheumatologist after a minimum of 6 months of follow-up and 22 patients had positive ultrasonography, 8 of whom were diagnosed with GCA and 4 with polymyalgia rheumatica. In our study, the sensitivity of ultrasonography was 42.6%, and the specificity was 65.7%. A total of 19 patients had a positive biopsy, all of them were diagnosed with GCA. In our study, the sensitivity of the biopsy was 73.7% and the specificity was 100%., Conclusions: In view of the data from our study, the usefulness of ultrasonography is questionable, and research about the role of ultrasonography in this disease should be further studied., (Copyright © 2018 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

- Abstract
The establishment of cartilage regenerative medicine is an important clinical issue, but the search for cell sources able to restore cartilage integrity proves to be challenging. Human mesenchymal stromal cells (MSCs) are prone to form epiphyseal or hypertrophic cartilage and have an age-related limited proliferation. On the other hand, it is difficult to obtain functional chondrocytes from human embryonic stem cells (ESCs). Moreover, the ethical issues associated with human ESCs are an additional disadvantage of using such cells. Since their discovery in 2006, induced pluripotent stems cells (iPSCs) have opened many gateways to regenerative medicine research, especially in cartilage tissue engineering therapies. iPSCs have the capacity to overcome limitations associated with current cell sources since large numbers of autologous cells can be derived from small starting populations. Moreover, problems associated with epiphyseal or hypertrophic-cartilage formation can be overcome using iPSCs. iPSCs emerge as a promising cell source for treating cartilage defects and have the potential to be used in the clinical field. For this purpose, robust protocols to induce chondrogenesis, both in vitro an in vivo, are required. This review summarises the recent progress in iPSC technology and its applications for cartilage repair.

- Abstract
Background: Calcium gluconate extravasation is a process that can cause serious lesions, such as necrosis and calcification of the soft tissues. The aim of the present study was to analyze the beneficial effects of four possible local antidotes for calcium gluconate extravasation: hyaluronidase, sodium thiosulfate, triamcinolone acetonide, and physiologic saline solution., Methods: Seventy-four BALB/c mice were used in the study. The substances selected for use in this study were calcium gluconate (4.6 mEq/ml), hyaluronidase (1500 IU/ml), sodium thiosulfate (25%), triamcinolone acetonide (40 mg/ml 0.5 mg/kg), and saline solution 0.9%. Five minutes were allowed to lapse after the calcium gluconate infiltration, and then an antidote was infiltrated. After 3 weeks, a skin biopsy was performed and a radiographic and histologic study was carried out., Results: Only in the group infiltrated with sodium thiosulfate did all skin lesions disappear after the 3-week period after infiltration. In the radiographic study, calcium deposits larger than 0.5 mm were observed in 40 percent of cases without an antidote, in 33 percent with triamcinolone acetonide, in 13 percent with a saline solution, and in none with thiosulfate and hyaluronidase. In the histologic study, calcium deposits were found in 53 percent of cases without antidote, 100 percent of cases with triamcinolone acetonide, 33 percent of cases with saline solution, and 13 percent of cases with sodium thiosulfate or hyaluronidase., Conclusion: Sodium thiosulfate and hyaluronidase prevent the development of calcium deposits after calcium gluconate extravasation.

- Abstract
Objective: To study the prevalence of osteoporosis and fracture probability in patients diagnosed with prostate cancer., Design: Observational descriptive transversal study. SITE: Study performed from Primary Care of Lugo in collaboration with Rheumatology and Urology Services of our referral hospital., Participants: Patients diagnosed with prostate cancer without bone metastatic disease from January to December 2012., Main Measurements: Epidemiologic, clinical, laboratory and densitometric variables involved in osteoporosis were collected. The likelihood of fracture was estimated by FRAX
® Tool., Results: Eighty-three patients met the inclusion criteria. None was excluded. The average age was 67 years. The Body Mass Index was 28.28. Twenty-five patients (30.1%) had previous osteoporotic fractures. Other prevalent risk factors were alcohol (26.5%) and smoking (22.9%). Eighty-two subjects had vitamin D below normal level (98.80%). Femoral Neck densitometry showed that 8.9% had osteoporosis and 54% osteopenia. The average fracture risk in this population, estimated by FRAX® , was 2.63% for hip fracture and 5.28% for major fracture. Cut level for FRAX® major fracture value without DXA >5% and ≥7.5% proposed by Azagra et al. showed 24 patients (28.92%) and 8 patients (9.64%) respectively., Conclusions: The prevalence of osteoporosis in this population was very high. The more frequent risk factors associated with osteoporosis were: previous osteoporotic fracture, alcohol consumption, smoking and family history of previous fracture. The probability of fracture using femoral neck FRAX® tool was low. Vitamin D deficiency was very common (98.8%)., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)- Published

- Abstract
This study aimed to generate a minimum list of structural and functional anatomical items about the pelvis/hip, knee, ankle/foot, gait, and lower limb innervation, which are most relevant to the practice of rheumatology. To determine their perceived relevance to clinical practice, seven members of the Mexican Clinical Anatomy Task Force compiled an initial list of 470 anatomical items. Ten local and international experts according to a 0-10 Likert scale ranked these items. Of the original list, 101 (21.48%) items were considered relevant (global rate >40). These included 36/137 (26.27%) pelvis and hip items, 25/82 (30.48%) knee items, 22/168 (13.98%) ankle/foot items, 11/68 (16.17%) neurologic items, and 7/15 (46.66%) gait-related items. We propose that these 101 anatomical items of the lower extremity, when added to the 115 anatomic items of the upper extremity and spine we previously reported, may represent an approximation to the minimal anatomical knowledge central to the competent practice of rheumatology. The meager representation of ankle and foot items may reflect a lesser emphasis in these anatomical regions during rheumatologic training. Attention to these and related items during rheumatologic training and beyond may sharpen the rheumatologist's ability in the differential diagnosis of regional pain syndromes as well as strengthen an endangered art: the rheumatologic physical examination.

- Abstract
Introduction: Calcium gluconate extravasation is a process, which, while not common, occurs more frequently in neonatal intensive care units. The aim of this study is to present a number of cases of calcium gluconate extravasation, which have occurred in our hospital, and to carry out a review of those clinical cases published in the literature to obtain relevant epidemiological data., Methods: Data were gathered on the medical histories of 5 patients who presented lesions secondary to calcium gluconate extravasation in our center. A review of the literature was also performed to include clinical cases of calcium gluconate extravasation already published., Results: Data were collected on 60 cases published in 37 articles. Most patients (55%) were neonates. The average age of these neonates was 8 days. The commonest location of injuries was the back of the hand and wrist (42%). The 2 most frequent symptoms were the appearance of erythema (65%) and swelling/edema (48%) followed by the appearance of skin necrosis (47%), indurated skin (33%), and yellow-white plaques or papules (33%). Most cases are cured within a period of 3 to 6 months. Fifty percent of patients required surgery, and in 13% of cases, skin grafts were performed. The most frequent histological finding was the presence of calcium deposits. Other histological findings described were the presence of necrosis, lymphohistiocytic infíltrate, and granulomas. Most histological findings were located in the dermis. Most x-rays showing calcium deposits had been performed at 3 to 4 weeks., Conclusions: Calcium gluconate extravasation is a process, which, although infrequent, is associated with serious skin and soft-tissue lesions, mainly affecting infants. Further studies are needed to determine possible specific procedures to be carried out in these cases.

- Abstract
Introduction: Knowledge of ovine mesenchymal stromal cells (oMSCs) is currently expanding. Tissue engineering combining scaffolding with oMSCs provides promising therapies for the treatment of osteochondral diseases., Purpose: The aim was to isolate and characterize oMSCs from bone marrow aspirates (oBMSCs) and to assess their usefulness for osteochondral repair using β-tricalcium phosphate (bTCP) and type I collagen (Col I) scaffolds., Methods: Cells isolated from ovine bone marrow were characterized morphologically, phenotypically, and functionally. oBMSCs were cultured with osteogenic medium on bTCP and Col I scaffolds. The resulting constructs were evaluated by histology, immunohistochemistry and electron microscopy studies. Furthermore, oBMSCs were cultured on Col I scaffolds to develop an in vitro cartilage repair model that was assessed using a modified International Cartilage Research Society (ICRS) II scale., Results: oBMSCs presented morphology, surface marker pattern and multipotent capacities similar to those of human BMSCs. oBMSCs seeded on Col I gave rise to osteogenic neotissue. Assessment by the modified ICRS II scale revealed that fibrocartilage/hyaline cartilage was obtained in the in vitro repair model., Conclusions: The isolated ovine cells were demonstrated to be oBMSCs. oBMSCs cultured on Col I sponges successfully synthesized osteochondral tissue. The data suggest that oBMSCs have potential for use in preclinical models prior to human clinical studies., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
This study aimed to identify the anatomical items of the upper extremity and spine that are potentially relevant to the practice of rheumatology. Ten rheumatologists interested in clinical anatomy who published, taught, and/or participated as active members of Clinical Anatomy Interest groups (six seniors, four juniors), participated in a one-round relevance Delphi exercise. An initial, 560-item list that included 45 (8.0 %) general concepts items; 138 (24.8 %) hand items; 100 (17.8 %) forearm and elbow items; 147 (26.2 %) shoulder items; and 130 (23.2 %) head, neck, and spine items was compiled by 5 of the participants. Each item was graded for importance with a Likert scale from 1 (not important) to 5 (very important). Thus, scores could range from 10 (1 × 10) to 50 (5 × 10). An item score of ≥40 was considered most relevant to competent practice as a rheumatologist. Mean item Likert scores ranged from 2.2 ± 0.5 to 4.6 ± 0.7. A total of 115 (20.5 %) of the 560 initial items reached relevance. Broken down by categories, this final relevant item list was composed by 7 (6.1 %) general concepts items; 32 (27.8 %) hand items; 20 (17.4 %) forearm and elbow items; 33 (28.7 %) shoulder items; and 23 (17.6 %) head, neck, and spine items. In this Delphi exercise, a group of practicing academic rheumatologists with an interest in clinical anatomy compiled a list of anatomical items that were deemed important to the practice of rheumatology. We suggest these items be considered curricular priorities when training rheumatology fellows in clinical anatomy skills and in programs of continuing rheumatology education.

Objective: To determine the clinical profile, degree of involvement and management in patients with knee, hip or hand osteoarthritis., Material and Method: Observational study (health centers from 14 autonomous regions, n=363 primary care physicians), involving patients with clinical and/or radiological criteria for osteoarthritis from the American College of Rheumatology, consecutively selected (n=1,258). Sociodemographic variables, clinical and radiological findings, comorbidity and therapeutic management were analyzed., Results: Mean age was 68.0±9.5 years old; 77.8% were women and 47.6% obese. Distribution by location was: 84.3% knee, 23.4% hip, 14.7% hands. All patients reported pain. The most frequent radiographic Kellgren-Lawrence grade was stage 3 for knee and hip (42.9% and 51.9%, respectively), and 3 (37.2%) and 2 (34.5%) for hip. Time since onset of osteoarthritis symptoms was 9.4±7.5 years, with a mean age at onset of around 60 years old and a family history of osteoarthritis in 66.0%. The most frequent comorbidities were: hypertension (55.1%), depression/anxiety (24.7%) and gastroduodenal diseases (22.9%). A total of 97.6% of the patients received pharmacological treatment, with oral analgesics (paracetamol) (70.5%) and oral NSAIDs (67.9%) being the most frequent drugs. Bilateral osteoarthritis was present in 76.9% of patients with knee osteoarthritis, 59.3% in hip and 94.7% in hands. Female gender and time since onset were associated with bilateral knee and hip osteoarthritis., Conclusions: The profile of the osteoarthritis patient is female, >65 years old, overweight/obese, with comorbidity, frequent symptoms and moderate radiologic involvement. Most of patients had bilateral osteoarthritis, associated with female gender and time since onset of disease. Paracetamol was the most common pharmacological treatment., (Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Reumatología y Colegio Mexicano de Reumatología. All rights reserved.)

- Abstract
Articular cartilage lesions which do not affect the integrity of subchondral bone, they are not able to repair it expontaneously. The asymptomatic nature of these lesions induces articular cartilage degeneration and development of an arthrosic process. To avoid the necessity to receive joint replacement surgery, it has been developed different treatments of cellular therapy which are focused to create new tissues whose structure, biochemistry composition and function will be the same than native articular cartilage. Approaches used to access the stream produce a fibrocartilaginose tissue which is not an articular cartilage. Implantation of autologous chondrocytes and autologous mosaicplasties induces a quality better articular cartilage. Furthermore both techniques involve damage in the sane cartilage; because of trying to get a big amount of chondrocytes or because of extraction osteochondral cylinder which will be implanted in the injured joint. The stem cells are a promising toll to repair articular cartilage, however they are in a previous experimentation step yet. Although the present studies using cellular therapy improves clinically and functionally, it is not able to regenerate an articular cartilage which offer resistance the degeneration process., (Copyright © 2007 Elsevier España S.L Barcelona.

- Abstract
We describe a 41-year-old patient with adult-onset dermatomyositis who developed persistent pneumomediastinum and severe subcutaneous emphysema due to end-stage interstitial lung disease. The diagnosis of dermatomyositis was based on proximal muscle weakness, electromyographic findings of inflammatory myopathy, and positive findings on muscle biopsy. Low levels of creatine kinase elevation were found at the time of diagnosis (a form of dermatomyositis which has been associated with a poor prognosis). The patient had no signs of cutaneous vasculitis. Despite treatment with prednisone and azathioprine, she died of intercurrent gram-negative sepsis 15 months after the diagnosis of dermatomyositis.
