The effects of improvement in upper extremity function on gait and balance in children with upper extremity affected.

BACKGROUND: This study aimed to investigate the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected. RESEARCH QUESTION: What are the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected? METHODS: Eighteen children with a diagnosis of rheumatologic diseases and 15 healthy children were evaluated with Shriners Hospital Upper Extremity Assessment, Jebsen-Taylor Hand Function Test, Abilhand Rheumatoid Arthritis Scale, 10-meter walk test and Childhood Health Assessment Questionnaire. For static balance assessment, the Biodex Balance was used. Ground reaction forces (peak forces (heel strike and push-off) and minimum force (loading response), single-limb support duration, Center-of-Force displacement and walking speed were evaluated with the Sensor Medica. Arm swing was evaluated with the Kinovea 2D motion analysis. RESULTS: Before treatment, single-limb support duration and push-off force was higher and center-of-force displacement was lower on affected side compared to unaffected side in rheumatologic group. After the 6-week rehabilitation program, upper extremity function, quality of life and functional gait score improved. Single-limb support duration decreased on affected side and increased on unaffected side. On affected side, push-off force decreased. The arm swing parameters were similar before and after treatment. SIGNIFICANCE: Improving upper extremity function can help with gait balance by decreasing the difference in walking and balance parameters between the affected and unaffected sides and providing for more symmetrical weight transfer.

Flares in IIMs and the timeline following COVID-19 vaccination: a combined analysis of the COVAD-1 and -2 surveys.

OBJECTIVES: Disease flares in the post-coronavirus disease 2019 (COVID-19) vaccination period represent a prominent concern, though risk factors are poorly understood. We studied these flares among patients with idiopathic inflammatory myopathies (IIMs) and other autoimmune rheumatic diseases (AIRDs). METHODS: The COVAD-1 and -2 global surveys were circulated in early 2021 and 2022, respectively, and we captured demographics, comorbidities, AIRDs details, COVID-19 infection history and vaccination details. Flares of IIMs were defined as (a) patient self-reported, (b) immunosuppression (IS) denoted, (c) clinical sign directed and (d) with >7.9-point minimal clinically significant improvement difference worsening of Patient-Reported Outcomes Measurement Information System (PROMIS) PROMISPF10a score. Risk factors of flares were analysed using regression models. RESULTS: Of 15 165 total respondents, 1278 IIMs (age 63 years, 70.3% female, 80.8% Caucasians) and 3453 AIRDs were included. Flares of IIM were seen in 9.6%, 12.7%, 8.7% and 19.6% patients by definitions (a) to (d), respectively, with a median time to flare of 71.5 (10.7-235) days, similar to AIRDs. Patients with active IIMs pre-vaccination (OR 1.2; 95% CI 1.03, 1.6, P = 0.025) were prone to flares, while those receiving rituximab (OR 0.3; 95% CI 0.1, 0.7, P = 0.010) and AZA (OR 0.3, 95% CI 0.1, 0.8, P = 0.016) were at lower risk. Female gender and comorbidities predisposed to flares requiring changes in IS. Asthma (OR 1.62; 95% CI 1.05, 2.50, P = 0.028) and higher pain visual analogue score (OR 1.19; 95% CI 1.11, 1.27, P < 0.001) were associated with disparity between self-reported and IS-denoted flares. CONCLUSION: A diagnosis of IIMs confers an equal risk of flares in the post-COVID-19 vaccination period to AIRDs, with active disease, female gender and comorbidities conferring a higher risk. Disparity between patient- and physician-reported outcomes represents a future avenue for exploration.

Quality of life of patients with rheumatic diseases during the COVID-19 pandemic: The biopsychosocial path.

BACKGROUND: Previous models that assess quality-of-Life (QoL) in patients with rheumatic diseases have a strong biomedical focus. We evaluated the impact of COVID-19 related-health care interruption (HCI) on the physical, psychological, social relationships and environment QoL-dimensions, and explored factors associated with QoL when patients were reincorporated to the outpatient clinic, and after six-month follow-up. PATIENTS AND METHODS: Study phase-1 consisted of a COVID-19 survey administered from June 24th-October 31st 2020, to outpatients with rheumatic diseases who had face-to-face consultation at outpatient clinic reopening. Study phase-2 consisted of 3 consecutive assessments of patient´s QoL (WHOQOL-BREF), disease activity/severity (RAPID-3), and psychological comorbidity/trauma (DASS-21 and IES-R) to patients from phase-1 randomly selected. Sociodemographic, disease and treatment-related information, and comorbidities were obtained. Multiple linear regression analysis identified factors associated with the score assigned to each WHOQOL-BREF dimension. RESULTS: Patients included (670 for phase-1 and 276 for phase-2), had primarily SLE and RA (44.2% and 34.1%, respectively), and all the dimensions of their WHOQOL-BREF were affected. There were 145 patients (52.5%) who referred HCI, and they had significantly lower dimensions scores (but the environment dimension score). Psycho-emotional factors (primarily feeling confused, depression and anxiety), sociodemographic factors (age, COVID-19 negative economic impact, years of scholarship, HCI and having a job), and biomedical factors (RAPID-3 score and corticosteroid use) were associated with baseline QoL dimensions scores. Psycho-emotional factors showed the strongest magnitude on dimensions scores. Most consistent predictor of six-month follow-up QoL dimensions scores was each corresponding baseline dimension score, while social determinants (years of scholarship and having a job), emotional factors (feeling bored), and biomedical aspects (RAPID 3) had an additional impact. CONCLUSIONS: HCI impacted the majority of patient´s QoL dimensions. Psycho-emotional, sociodemographic and biomedical factors were consistently associated with QoL dimensions scores, and these consistently predicted the QoL trajectory.

Pediatric Rheumatologic Effects of COVID-19.

A multisystem inflammatory syndrome (MISC) can result from COVID-19 infection in previously healthy children and adolescents. It is potentially life threatening and is treated initially with intravenous immunoglobulin and aspirin but may require anti-inflammatory monoclonal antibody treatment in severe cases. SARS-CoV-2 infection can cause macrophage activation syndrome, chilblains, and flares of existing rheumatologic diseases. The pandemic has led to later presentation of some rheumatologic conditions as parents and patients have avoided health care settings. PubMed and Google scholar have been utilized to review the literature on the rheumatologic conditions resulting from COVID-19 and the current treatment options.

Detection of microvascular changes in systemic sclerosis and other rheumatic diseases.

Morphological and functional analysis of the microcirculation are objective outcome measures that are recommended for use in the presence of clinical signs of altered peripheral blood flow (such as Raynaud phenomenon), which can occur in systemic sclerosis (SSc) and other autoimmune rheumatic diseases. Several advanced non-invasive tools are available for monitoring the microcirculation, including nailfold videocapillaroscopy, which is the best-studied and most commonly used method for distinguishing and quantifying microvascular morphological alterations in SSc. Nailfold videocapillaroscopy can also be used alongside laser Doppler techniques to assist in the early diagnosis and follow-up of patients with dermatomyositis or mixed connective tissue disease. Power Doppler ultrasonography, which has been used for many years to evaluate the vascularity of synovial tissue in rheumatoid arthritis, is another promising tool for the analysis of skin and nailbed capillary perfusion in other autoimmune rheumatic diseases. Other emerging methods include raster-scanning optoacoustic mesoscopy, which offers non-invasive high-resolution 3D visualization of capillaries and has been tested in psoriatic arthritis and SSc. The principle functions and operative characteristics of several non-invasive tools for analysing microvascular changes are outlined in this Review, and the clinical roles of validated or tested imaging methods are discussed for autoimmune rheumatic diseases.

COVID-19 Among Patients With Inflammatory Rheumatic Diseases.

BACKGROUND: The course of novel coronavirus disease 2019 (COVID-19) has been of special concern in patients with inflammatory rheumatic diseases (IRDs) due to the immune dysregulation that may be associated with these diseases and the medications used for IRDs, that may affect innate immune responses. OBJECTIVE: In this cohort study, we aimed to report the disease characteristics and variables associated with COVID-19 outcome among Turkish patients with IRDs. METHODS: Between April and June, 2020, 167 adult IRD patients with COVID-19 were registered from 31 centers in 14 cities in Turkey. Disease outcome was classified in 4 categories; (i) outpatient management, (ii) hospitalization without oxygen requirement, (iii) hospitalization with oxygen requirement, and (iv) intensive care unit (ICU) admission or death. Multivariable ordinal logistic regression analysis was conducted to determine variables associated with a worse outcome. RESULTS: 165 patients (mean age: 50 ± 15.6 years, 58.2% female) were included. Twenty-four patients (14.5%) recovered under outpatient management, 141 (85.5%) were hospitalized, 49 (30%) required inpatient oxygen support, 22 (13%) were treated in the ICU (17 received invasive mechanic ventilation) and 16 (10%) died. Glucocorticoid use (OR: 4.53, 95%CI 1.65-12.76), chronic kidney disease (OR: 12.8, 95%CI 2.25-103.5), pulmonary disease (OR: 2.66, 95%CI 1.08-6.61) and obesity (OR: 3.7, 95%CI 1.01-13.87) were associated with a worse outcome. Biologic disease-modifying antirheumatic drugs (DMARDs) do not seem to affect COVID-19 outcome while conventional synthetic DMARDs may have a protective effect (OR: 0.36, 95%CI 0.17-0.75). Estimates for the associations between IRD diagnoses and outcome were inconclusive. CONCLUSIONS: Among IRD patients with COVID-19, comorbidities and glucocorticoid use were associated with a worse outcome, while biologic DMARDs do not seem to be associated with a worse outcome.

Prealbumin Correlates with C-reactive Protein in Rheumatic Musculoskeletal Diseases.

OBJECTIVE: Prealbumin is a blood component tested for nutrition monitoring, which could be affected during inflammation. This study aimed to investigate the relationships between prealbumin and C-reactive protein (CRP) in inflammatory rheumatic musculoskeletal diseases (RMDs), including Takayasu arteritis, antineutrophil cytoplasmic antibody-associated vasculitis, systemic lupus erythematosus, Behcet's disease and polymyositis/dermatomyositis. METHODS: A total of 52 healthy controls and 508 RMD patients were included. We collected 3714 clinical and laboratory records from June 2011 to August 2019, and the longest follow-up period was eleven years. The associations between prealbumin and CRP, the globulin gap, the albumin-to-globulin ratio, and IgG were evaluated. RESULTS: Prealbumin had a high correlation coefficient (r=-0.497, P<0.001), consistent changes over time with CRP, and a high area under the curve [AUC=0.777 (95% CI 0.76-0.795)] for CRP. The statistical relationship between the prealbumin and CRP was not affected by sex, ethnicity or age. Among RMDs, prealbumin showed the strongest correlation with CRP in Takayasu arteritis (r=0.607, P<0.001). In addition, a moderate relationship was observed between prealbumin and IgG, the globulin gap and the albumin-to-globulin ratio. CONCLUSION: Prealbumin is closely related to CRP in Chinese patients with five chronic inflammatory RMDs, which may be due to the influence of chronic inflammation during the course of disease.

Lung clearance index and diffusion capacity for CO to detect early functional pulmonary impairment in children with rheumatic diseases.

BACKGROUND: In adults with rheumatic diseases pulmonary complications are relevant contributors to morbidity and mortality. In these patients diffusion capacity for CO (DLCO) is an established method to detect early pulmonary impairment. Pilot studies using DLCO indicate that early functional pulmonary impairment is present even in children with rheumatic disease albeit not detectable by spirometry and without clinical signs of pulmonary disease. Since the lung clearance index (LCI) is also a non-invasive, feasible and established method to detect early functional pulmonary impairment especially in children and because it requires less cooperation (tidal breathing), we compared LCI versus DLCO (forced breathing and breath-holding manoeuvre) in children with rheumatic diseases. FINDINGS: Nineteen patients (age 9-17 years) with rheumatic disease and no clinical signs of pulmonary disease successfully completed LCI and DLCO during annual check-up. In 2 patients LCI and DLCO were within physiological limits. By contrast, elevated LCI combined with physiological results for DLCO were seen in 8 patients and in 9 patients both, the LCI and DLCO indicate early functional pulmonary changes. Overall, LCI was more sensitive than DLCO to detect early functional pulmonary impairment (p = 0.0128). CONCLUSIONS: Our findings suggest that early functional pulmonary impairment is already present in children with rheumatic diseases. LCI is a very feasible and non-invasive alternative for detection of early functional pulmonary impairment in children. It is more sensitive and less cooperation dependent than DLCO. Therefore, we suggest to integrate LCI in routine follow-up of rheumatic diseases in children.

Effects of physical activity on vascular function in autoimmune rheumatic diseases: a systematic review and meta-analysis.

OBJECTIVES: To summarize existing evidence and quantify the effects of physical activity on vascular function and structure in autoimmune rheumatic diseases (ARDs). METHODS: Databases were searched (through March 2020) for clinical trials evaluating the effects of physical activity interventions on markers of micro- and macrovascular function and macrovascular structure in ARDs. Studies were combined using random effects meta-analysis, which was conducted using Hedges' g. Meta-analyses were performed on each of the following outcomes: microvascular function [i.e. skin blood flow or vascular conductance responses to acetylcholine (ACh) or sodium nitropusside (SNP) administration]; macrovascular function [i.e. brachial flow-mediated dilation (FMD%) or brachial responses to glyceryl trinitrate (GTN%); and macrovascular structure [i.e. aortic pulse wave velocity (PWV)]. RESULTS: Ten studies (11 trials) with a total of 355 participants were included in this review. Physical activity promoted significant improvements in microvascular [skin blood flow responses to ACh, g = 0.92 (95% CI 0.42, 1.42)] and macrovascular function [FMD%, g = 0.94 (95% CI 0.56, 1.02); GTN%, g = 0.53 (95% CI 0.09, 0.98)]. Conversely, there was no evidence for beneficial effects of physical activity on macrovascular structure [PWV, g = -0.41 (95% CI -1.13, 0.32)]. CONCLUSIONS: Overall, the available clinical trials demonstrated a beneficial effect of physical activity on markers of micro- and macrovascular function but not on macrovascular structure in patients with ARDs. The broad beneficial impact of physical activity across the vasculature identified in this review support its role as an effective non-pharmacological management strategy for patients with ARDs.

Managing Cardiovascular Risk in Patients with Rheumatic Disease.

Individuals with rheumatoid arthritis, systemic lupus erythematosus, or gout have increased risk of cardiovascular disease (CVD) compared with the general population. This risk relates to a combination of traditional cardiovascular risk factors and disease-specific factors. Screening for CVD is important because CVD contributes to significant morbidity and mortality. Management includes tight control of disease activity to reduce inflammation, but with care to minimize use of nonsteroidal anti-inflammatory drugs and prolonged courses of high-dose corticosteroids. Traditional cardiovascular risk factors should be managed with a combination of lifestyle interventions and pharmacotherapy. The decision to start antihypertensive and lipid-lowering therapy should be based on individual CVD risk.

Disordered eating among adolescents with chronic pain: the experience of a pediatric rheumatology subspecialty pain clinic.

BACKGROUND: Disordered eating and chronic pain often co-occur in adolescents, but the relationship between these conditions is not well understood. We aimed to determine the prevalence of and to identify the clinical characteristics associated with the presence of disordered eating among adolescents with chronic musculoskeletal pain (CMP) presenting to a pediatric rheumatology subspecialty pain clinic. METHODS: This was a retrospective cohort study of pediatric patients presenting to a pediatric rheumatology subspecialty pain clinic for an initial consultation from March 2018 to March 2019. We complemented data from an existing patient registry with secondary chart review for patients identified with disordered eating. We compared patient characteristics based on the presence or absence of disordered eating among adolescents with CMP. Logistic regression modeling was used to determine factors associated with disordered eating. RESULTS: Of the 228 patients who were seen for an initial consultation in the pain clinic in 1 year, 51 (22.4%) had disordered eating. Only eight (15.7%) of the 51 patients identified with disordered eating had a previously documented formal eating disorder diagnosis. Through multivariate logistic regression modeling, we found that disordered eating was associated with older age, higher functional disability, presence of abdominal pain, presence of gastrointestinal comorbidities, and presence of anxiety (all p < 0.05). CONCLUSIONS: Adolescents with chronic pain, especially those who experience gastrointestinal issues, anxiety, and greater functional disability, should be evaluated for disordered eating by the treating clinician in order to ensure timely and appropriate treatment.

The impact of shrunken pore syndrome in patient with rheumatic diseases on bone mineral metabolism.

The study aimed to investigate the influence of shrunken pore syndrome (SPS), defined as a cystatin C (CysC)-based estimated glomerular filtration rate (eGFRCysC) <60% of the creatinine (Cr)-based eGFR (eGFRCr), on bone mineral density (BMD) in patients with rheumatic diseases. A total of 831 patients with rheumatic diseases were enrolled in the study. Patients were classified into the SPS group (G-SPS) and non-SPS group (G-nSPS). The correlation between the presence of SPS and BMD of the lumbar spine (BMD_LS), BMD of the femoral neck (BMD_FN), serum parathyroid hormone (PTH) level, chronic kidney dysfunction (CKD), and parameters were evaluated statistically. The prevalence of SPS was 4.0%. Serum PTH level, tartrate-resistant acid phosphatase-5b (TRACP-5b), and eGFRCr in the G-SPS were significantly higher than in the G-nSPS, whereas BMD_LS and BMD_FN in the G-SPS were significantly lower than in the G-nSPS. Serum PTH level was significantly correlated with CysC. BMD_LS had no significant correlation with BMD_FN. The presence of SPS was the only factor that demonstrated significant negative correlation with both BMD_LS and BMD_FN. Relationship between BMD_LS and the presence of SPS was present regardless of CKD stage; however, the negative relationship between BMD_LS and serum PTH was observed only in CKD stage 1 and 2 patients. BMD_FN demonstrated significant negative correlation with serum PTH in the group with progression of CKD. These results suggest that there is a serious potential risk of osteoporosis in patients with SPS and increased PTH, and BMD_LS poses a higher risk in CKD stage 1 and 2.

Autoimmune gastrointestinal dysmotility: the interface between clinical immunology and neurogastroenterology.

Autoimmune gastrointestinal dysmotility (AGID), an idiopathic or paraneoplastic phenomenon, is a clinical form of limited autoimmune dysautonomia. The symptoms of AGID and gastrointestinal manifestations in patients with autoimmune rheumatic diseases are overlapping. Antineuronal autoantibodies are often detected in patients with AGID. Autoantibodies play a key role in GI dysmotility; however, whether they cause neuronal destruction is unknown. Hence, the connection between the presence of these autoantibodies and the specific interference in synaptic transmission in the plexus ganglia of the enteric nervous system has to be determined. The treatment options for AGID are not well-defined. However, theoretically, immunomodulatory therapies have been shown to be effective and are therefore used as the first line of treatment. Nonetheless, diverse combined immunomodulatory therapies should be considered for intractable cases of AGID. We recommend comprehensive autoimmune evaluation and cancer screening for clinical diagnosis of AGID. Univocal diagnostic criteria, treatment protocols, and outcome definitions for AGID are required for prompt diagnosis and treatment and appropriate management of immunotherapy, which will circumvent the need for surgeries and improve patient outcome. In conclusion, AGID, a disease at the interface of clinical immunology and neurogastroenterology, requires further investigations and warrants cooperation among specialists, especially clinical immunologists, gastroenterologists, and neurologists.

Impact of the COVID-19 pandemic on the disease course of patients with inflammatory rheumatic diseases: results from the Swiss Clinical Quality Management cohort.

OBJECTIVES: To investigate whether the transient reduction in rheumatology services imposed by virus containment measures during the COVID-19 pandemic was associated with disease worsening in axial spondyloarthritis (axSpA), rheumatoid arthritis (RA) or psoriatic arthritis (PsA). METHODS: Patient-reported disease activity assessed during face-to-face visits and/or via a smartphone application were compared between three periods of each 2 months duration (before, during and after the COVID-19-wave) from January to June 2020 in 666 patients with axSpA, RA and PsA in the Swiss Clinical Quality Management cohort. RESULTS: The number of consultations dropped by 52%, whereas the number of remote assessments increased by 129%. The proportion of patients with drug non-compliance slightly increased during the pandemic, the difference reaching statistical significance in axSpA (19.9% vs 13.2% before the pandemic, p=0.003). The proportion of patients with disease flares remained stable (<15%). There was no increase in mean values of the Bath Ankylosing Disease Activity Index, the Rheumatoid Arthritis Disease Activity Index-5 and the Patient Global Assessment in patients with axSpA, RA and PsA, respectively. CONCLUSION: A short interruption of in-person patient-rheumatologist interactions had no major detrimental impact on the disease course of axSpA, RA and PsA as assessed by patient-reported outcomes.

Positive Psychological Factors and Impairment in Rheumatic and Musculoskeletal Disease: Do Psychopathology and Sleep Quality Explain the Linkage?

OBJECTIVE: Little is known about potential mechanisms of action linking protective positive psychological variables and functional disability in patients with rheumatic and musculoskeletal disease. The present study was undertaken to examine symptoms of psychopathology, including stress, depression, anxiety, and sleep quality, as serial mediators of the association between gratitude, self-compassion, self-forgiveness, and functional impairment. METHODS: We assessed risk and protective factors for functional disability in patients with fibromyalgia (FM), osteoarthritis (OA), rheumatoid arthritis (RA), and ankylosing spondylitis (AS) who were recruited from an Austrian health care facility. Respondents completed online surveys, including the Gratitude Questionnaire 6-item form, the Self-Compassion Scale short form, the Self-Forgiveness and Forgiveness of Others Index, the Perceived Stress Scale 4, the Patient Health Questionnaire 2, the 2-item Generalized Anxiety Disorder Scale, the Sleep Condition Indicator, and the Health Assessment Questionnaire. Bivariate and serial mediation analyses were conducted. RESULTS: For our sample of 1,218 patients (52% female, n = 632; AS [37%], OA [34%], RA [14%], and FM [24%]), stress, depression, and anxiety, in parallel as first-order mediators, and sleep quality as a second-order mediator, explained the association between positive psychological variables and functional disability. CONCLUSION: Positive psychological factors exert a beneficial downstream effect on mental well-being, sleep health, and health-related functional impairment. Therapeutic promotion of gratitude, self-compassion, and self-forgiveness may improve mental and physical health in patients with rheumatic and musculoskeletal disease.

Exploring the Preferences of Women Regarding Sexual and Reproductive Health Care in the Context of Rheumatology: A Qualitative Study.

OBJECTIVE: To explore the sexual and reproductive health (SRH) care and counseling needs of young women with rheumatic diseases in the context of their rheumatology care. METHODS: Semistructured qualitative telephone interviews were conducted with female patients with rheumatic diseases ages 18-45 years (n = 30). Women were recruited from outpatient rheumatology clinics in western Pennsylvania. Interviews were audiorecorded and transcribed verbatim. A codebook was inductively developed based on the interview transcripts, and the finalized coding was used to conduct a thematic analysis. RESULTS: Four themes emerged from interviews: 1) women want rheumatologists to initiate conversations about SRH and to revisit the conversation over time; 2) women desire clear and complete information regarding fetal, pregnancy, and infertility risks associated with their diseases and disease-modifying antirheumatic drugs (DMARDs); 3) women want to be treated holistically, with SRH addressed in the context of their life circumstances and personal values in addition to their rheumatic diseases; 4) women generally feel that they are intermediaries between their rheumatologists and obstetrician-gynecologists (OB/GYNs), but preferred for providers to communicate directly with one another about their SRH. CONCLUSION: Patients strongly desired rheumatologists to play an active role in their SRH, by initiating family planning conversations, providing SRH education in the context of their diseases and DMARDs, and directly coordinating SRH care with OB/GYNs. To meet patients' SRH needs, further work is needed to clarify the specific role of rheumatologists in providing SRH care and to identify ways to better facilitate communication between rheumatologists and reproductive health care providers.

EULAR recommendations for a core data set for pregnancy registries in rheumatology.

BACKGROUND AND OBJECTIVE: There is an urgent need for robust data on the trajectories and outcomes of pregnancies in women with inflammatory rheumatic diseases (IRD). In particular when rare outcomes or rare diseases are to be investigated, collaborative approaches are required. However, joint data analyses are often limited by the heterogeneity of the different data sources.To facilitate future research collaboration, a European League Against Rheumatism (EULAR) Task Force defined a core data set with a minimum of items to be collected by pregnancy registries in rheumatology covering the period of pregnancy and the 28-day neonatal phase in women with any underlying IRD. METHODS: A stepwise process included a two-round Delphi survey and a face-to-face meeting to achieve consensus about relevant items. RESULTS: A total of 64 multidisciplinary stakeholders from 14 different countries participated in the two rounds of the Delphi process. During the following face-to-face meeting of the EULAR Task Force, consensus was reached on 51 main items covering 'maternal information', 'pregnancy' and 'treatment'. Generic instruments for assessment are recommended for every item. Furthermore, for the five most frequent IRDs rheumatoid arthritis, spondyloarthritis, juvenile idiopathic arthritis, systemic lupus erythematosus and other connective tissue diseases, disease-specific laboratory markers and disease activity measurements are proposed. CONCLUSION: This is the first consensus-based core data set for prospective pregnancy registries in rheumatology. Its purpose is to stimulate and facilitate multinational collaborations that aim to increase the knowledge about pregnancy course and safety of treatment in women with IRDs during pregnancy.

Frailty in Rheumatic Diseases.

Frailty is a syndrome characterized by the decline in the physiologic reserve and function of several systems, leading to increased vulnerability and adverse health outcomes. While common in the elderly, recent studies have underlined the higher prevalence of frailty in chronic diseases, independent of age. The pathophysiological mechanisms that contribute to frailty have not been completely understood, although significant progresses have recently been made. In this context, chronic inflammation is likely to play a pivotal role, both directly and indirectly through other systems, such as the musculoskeletal, endocrine, and neurological systems. Rheumatic diseases are characterized by chronic inflammation and accumulation of deficits during time. Therefore, studies have recently started to explore the link between frailty and rheumatic diseases, and in this review, we report what has been described so far. Frailty is dynamic and potentially reversible with 8.3%-17.9% of older adults spontaneously improving their frailty status over time. Muscle strength is likely the most significant influencing factor which could be improved with training thus pointing at the need to maintain physical activity. Not surprisingly, frailty is more prevalent in patients affected by rheumatic diseases than in healthy controls, regardless of age and is associated with high disease activity to affect the clinical outcomes, largely due to chronic inflammation. More importantly, the treatment of the underlying condition may prevent frailty. Scales to assess frailty in patients affected by rheumatic diseases have been proposed, but larger casuistries are needed to validate disease-specific indexes, which could allow more accurate prognostic estimates than demographic and disease-related variables alone. Frail patients can be more vulnerable and more difficult to treat, due to the risk of side effects, therefore frailty should be taken into account in clinical decisions. Clinical trials addressing frailty could identify patients who are less likely to tolerate potentially toxic medications and might benefit from more conservative regimens. In conclusion, the implementation of the concept of frailty in rheumatology will allow a better understanding of the patient global health, a finest risk stratification and a more individualized management strategy.

Sex steroids and autoimmune rheumatic diseases: state of the art.

In autoimmune rheumatic diseases, oestrogens can stimulate certain immune responses (including effects on B cells and innate immunity), but can also have dose-related anti-inflammatory effects on T cells, macrophages and other immune cells. By contrast, androgens and progesterone have predominantly immunosuppressive and anti-inflammatory effects. Hormone replacement therapies and oral contraception (and also pregnancy) enhance or decrease the severity of autoimmune rheumatic diseases at a genetic or epigenetic level. Serum androgen concentrations are often low in men and in women with autoimmune rheumatic diseases, suggesting that androgen-like compounds might be a promising therapeutic approach. However, androgen-to-oestrogen conversion (known as intracrinology) is enhanced in inflamed tissues, such as those present in patients with autoimmune rheumatic diseases. In addition, it is becoming evident that the gut microbiota differs between the sexes (known as the microgenderome) and leads to sex-dependent genetic and epigenetic changes in gastrointestinal inflammation, systemic immunity and, potentially, susceptibility to autoimmune or inflammatory rheumatic diseases. Future clinical research needs to focus on the therapeutic use of androgens and progestins or their downstream signalling cascades and on new oestrogenic compounds such as tissue-selective oestrogen complex to modulate altered immune responses.
