Systemic sclerosis in a patient with Turner syndrome: A case report and a review of associated autoimmune diseases

Turner's syndrome (TS) is one of the most common sex chromosome disorders caused by numeric or structural abnormalities of the X chromosome. A case of TS and Systemic Sclerosis (SSc) is reported, along with a summary of all associated TS/autoimmune diseases described in English literature from 1948 to 2020, using a search in MEDLINE (Pubmed). A 32-year-old woman affected by TS was seen due to inflammatory arthralgia in small joints and dysphagia, as well as a two-year history of Raynaud's phenomenon and puffy hands. Biohumoural laboratory tests and severity scales revealed changes that allowed us to diagnose SSc. This case report emphasises the role played by sex hormones and chromosomal abnormalities in the pathogenesis of autoimmune disorders, and to our knowledge, this is the only case described in literature of a TS patient who developed SSc.

El síndrome de Turner (TS) es uno de los trastornos cromosómicos sexuales más comunes causados por anomalías numéricas o estructurales del cromosoma X. En este documento informamos de un caso de TS y esclerosis sistémica (SSc) y resumimos toda la asociación de TS/enfermedades autoinmunes descrita en la literatura inglesa de 1948 a 2020, encontrada buscando en MEDLINE (PubMed). Una mujer de 32 arios afectada por TS acudió a nuestra observación debido a la artralgia inflamatoria en pequenas articulaciones y disfagia y 2 anos de historia del fenómeno de Raynaud y las manos hinchadas. El laboratorio biohumoral y las pruebas instrumentales revelaron alteraciones que nos permitieron diagnosticar SSc. Nuestro informe de caso hace hincapié en el papel desempefíado por las hormonas sexuales y las anomalías cromosómicas en la patogénesis del trastorno autoinmune; y hasta nuestro conocimiento, este es el único caso descrito en la literatura de un paciente TS que desarrolló SSc.

Preliminary Data on Post Market Safety Profiles of COVID 19 Vaccines in Rheumatic Diseases: Assessments on Various Vaccines in Use, Different Rheumatic Disease Subtypes, and Immunosuppressive Therapies: A Two-Centers Study.

An increased risk of developing severe infections has been evidenced in rheumatic disease (RD) patients, and anti-COVID-19 vaccination is strictly recommended for RD patients. However, up to now, no data are available on safety, immunogenicity and efficacy of COVID-19 vaccinations in RD patients. The possible development of adverse events (AEs), including the flare-up of underlying RD, represents a matter of growing importance. The aim of our study is to assess, in RD patients, the safety profile of different types of approved vaccines and the possible influence of immunosuppressive therapies and clinical or demographic characteristics of RD patients on development of AEs. Participants (n = 185; 30.7%) received anti-COVID-19 vaccinations, 137 with autoimmune/chronic inflammatory RD (Au/cIn-RD) and 48 with nonautoimmune/chronic inflammatory RD (no-Au/cIn-RD). AEs were recorded in 42% of patients after the first dose of vaccine, and in 26% of patients after the second dose. The most common reported AEs after anti-COVID 19 vaccines were site injection pain (17%), headache (12%), fever (12%), myalgia (10%) and fatigue (10%). Relapses of the underlying Au/c-In-RD were recorded in 2.2% of patients after the first dose of vaccine. In Au/c-In-RD the risk of developing AEs after the first dose of vaccine was lower in older patients (OR = 0.95; p = 0.001), and in the group of patients with complete control of RD (OR: 0.2; p = 0.010). A lower percentage of AEs was observed in patients with complete control of their Au/cIn-RD (29%) compared to those with low (57%) or moderate-high disease activity (63%) (p = 0.002 and p = 0.006 respectively). In this study all types of COVID-19 vaccines in use in Italy seemed safe in RD patients. The results of this study might provide reassuring information for Au/cIn RD patients and clinicians and could strengthen the data on vaccine safety to guide the use of COVID-19 vaccines in Au/cIn-RD on immunosuppressive agents.

Influence of glucocorticoid treatment on trabecular bone score and bone remodeling regulators in early rheumatoid arthritis.

BACKGROUND: Glucocorticoids (GC) modulate several regulators involved in the pathogenesis of bone changes in rheumatoid arthritis (RA). Trabecular bone score (TBS) allows the indirect assessment of bone quality. The aim of this study was to investigate the effects of GC on TBS and serum levels of bone turnover regulators in patients with recent-onset RA. MATERIALS AND METHODS: Forty-seven subjects with recent-onset RA (< 6 months) were classified in two groups, low (lGC) and high (hGC) glucocorticoids, according to glucocorticoid dose regimens. Bone mineral density (BMD), TBS, and circulating Dickkopf-1 (Dkk1), sclerostin, osteoprotegerin (OPG), and RANK-L were evaluated at baseline and 6 and 12 months. RESULTS: BMD significantly declined after 12 months with no significant difference between the lGC and hGC group, whereas TBS decreased in the hGC group only. Circulating OPG decreased during the follow-up period, the reduction being significantly greater in hGC group; conversely, sclerostin and RANK-L serum increased, in a significantly greater extent in the hGC group. TBS inversely correlated with sclerostin, RANK-L, and Dkk1 circulating levels whereas directly correlated with OPG circulating levels. GC cumulative dose showed an inverse relationship with BMD in both the hGC and lGC groups; TBS values showed an inverse relationship with GC cumulative dose in the hGC group only. GC cumulative dose was associated to higher sclerostin and lower OPG serum levels. TBS did not correlate with disease activity whereas BMD was inversely related to disease activity. CONCLUSIONS: In early RA, GC exposure contributes to the reduction of BMD and affects bone quality depending on dose regimens. TBS could be a useful tool to evaluate the negative effect of GC on bone microarchitecture. TRIAL REGISTRATION: This study was ancillary to a parallel-group observational prospective study which was approved by the medical local ethics committee (protocol number DDG 334/19-06-2019).

Possible role of higher serum level of myoglobin as predictor of worse prognosis in Sars-Cov 2 hospitalized patients. A monocentric retrospective study.

BACKGROUND: Limited data on myoglobin and infectious diseases are available. In this study, we evaluate the potential role of myoglobin in predicting poor outcome in patients with Sars-Cov2 pneumonia. METHODS: One hundred and twenty-one Sars-Cov 2 patients with an average age of 69.9 ± 13.2 years, and symptoms duration of 8.8 ± 7.9 days were enrolled in the study. At the admission, the serum levels of myoglobin, erythrocyte sedimentation rate, C reactive protein (CRP), procalcitonin, ferritin, creatine phosphokinase, creatinine, fibrinogen, d-dimers, lactic dehydrogenase, troponin (Tn-I), creatine kinase myocardial band (CK-MB), complement fractions C3 and C4, immunoglobulins, interleukin 6 were evaluated. We also assessed the patients' complete clinical history and performed a thorough physical examination including age, disease history, and medications. RESULTS: Twenty-four (20%) patients died, and 18 (15%) patients required intensive care. The mean time between symptoms onset and death was 12.4 days ± 9.1. Univariate analysis of the patients' data highlighted some independent risk factors for mortality in COVID-19, including higher neutrophils rate (HR: 1.171), lower lymphocyte rate (HR: 0.798), high CK-MB serum levels (HR: 1.6), high Tn-I serum levels (HR: 1.03), high myoglobin serum levels (HR: 1.014), Alzheimer (HR 5.8), and higher CRP values (HR: 1.011). Cox regression analysis model revealed that higher serum values of myoglobin (HR 1.003; 95%CI: 1.001-1.006; p = 0.01), and CRP (HR 1.012; 95% CI: 1.001-1.023; p = 0.035) could be predictors of mortality in COVID-19 patients. The value of the myoglobin level for predicting 28 days-mortality using ROC curve was 121.8 ng/dL. Lower survival rate was observed in patients with serum levels of myoglobin>121.8 ng/dL (84% vs 20% respectively, p = 0.0001). CONCLUSION: Our results suggest that higher serum levels of myoglobin could be a considerable and effective predictor of poor outcomes in COVID-19 patients; a careful follow-up in these patients is strongly suggested. The possibility of enhancing these findings in other cohorts of COVID-19 patients could validate the clinical value of myoglobin as a biomarker for worse prognosis in COVID-19.

Off-label use of anti-IL-1 drugs in rheumatic diseases.

Interleukin-1 (IL-1) plays a key role in the pathogenesis of different rheumatic diseases. There are now several agents available on the market capable of blocking IL-1. The proven effectiveness and excellent safety of these drugs makes them a possible therapeutic option in the treatment of IL-1 driven diseases, when previous therapies are contraindicated or ineffective. This article discusses the European wide off-label use of these drugs for the treatment of rheumatic diseases.

Changes in serum adipokines profile and insulin resistance in patients with rheumatoid arthritis treated with anti-TNF-α.

Background: Rheumatoid arthritis (RA) is a chronic inflammatory joint disease characterized by an altered glucose and lipid metabolism. Tumor necrosis factor alpha (TNF-α) is involved in the pathogenesis of both RA and metabolic syndrome. This study evaluated the effects of anti-TNF-α agents (adalimumab, etanercept, infliximab) on lipid and glucose metabolism in patients with RA.Methods: A total of 33 RA, biological therapy-naive patients were recruited. Changes in Disease Activity, Body Mass Index, resistin, leptin and adiponectin serum levels, lipid profile, atherogenic index, insulin sensitivity index, and insulin resistance index were evaluated at baseline and after anti-TNF-α treatments.Results: Anti-TNF-α treatment was effective in reducing disease activity. An inverse relationship between disease activity and adiponectin levels was found, whereas leptin and resistin levels directly correlated with disease activity. TNF-α therapy significantly reduced leptin, resistin, and increased adiponectin. TNF-α inhibition resulted in a reduction of atherogenic index and insulin resistance index while increased insulin sensitivity index.Conclusion: Anti-TNF-α agents could have a crucial role in modifying the impact of lipid profile and glucose levels dysregulation in RA patients. TNF-α inhibition may be a potential strategy for the prevention of metabolic syndrome and could play a role in the reduction of cardiovascular risk in RA.

Rheumatologic and extraintestinal manifestations of inflammatory bowel diseases.

Inflammatory bowel diseases (IBDs) often present as a complex inflammatory process wherein colon lesions (ulcerative colitis, UC) or widespread ulceration and fissure (Crohn's disease, CD) might be accompanied by ancillary extraintestinal manifestations (EIMs) that could involve almost every organ system, but also by autoimmune disorders ranging from psoriasis and rheumatoid arthritis to connective tissue diseases. Certain EIMs are more common related to the activity of the IBD (joint, skin, ocular and oral manifestations), other EIMs typically run a course independent of the IBD activity (hepatobiliary disorders) and some are non-specific disorders (osteoporosis and amyloidosis). This paper reviews the most common extraintestinal and rheumatologic manifestations of UC and CD. They may produce greater morbidity than the underlying intestinal disease and may even be the initial presenting symptoms of the IBD. Thus, early recognition of these manifestations should help guide therapy that will reduce overall morbidity in affected patients. Key Message A complete review on the most common extraintestinal and rheumatologic manifestations of ulcerative colitis and Crohn's disease.

Relationship between Body Mass Composition, Bone Mineral Density, Skin Fibrosis and 25(OH) Vitamin D Serum Levels in Systemic Sclerosis.

A reduced bone mineral density (BMD) is observed in several rheumatic autoimmune diseases, including Systemic Sclerosis (SSc); nevertheless, data concerning the possible determinants of bone loss in this disease are not fully investigated. The aim of this study is to evaluate the relationship between BMD, body mass composition, skin sclerosis and serum Vitamin D levels in two subsets of SSc patients. 64 post-menopausal SSc patients, classified as limited cutaneous (lcSSc) or diffuse cutaneous (dcSSc) SSc, were studied. As control, 35 healthy post-menopausal women were recruited. Clinical parameters were evaluated, including the extent of skin involvement. BMD at lumbar spine, hip, femoral neck and body mass composition were determined by dual-energy X-ray absorptiometry. Serum calcium, phosphorus, alkaline phosphatase, urine pyridinium cross-links, intact parathyroid hormone and 25-hydroxyvitamin D (25OHD) were measured. BMD at spine, femoral neck and total hip was significantly lower in SSc patients compared to controls. In dcSSc subset, BMD at spine, femoral neck and total hip was significantly lower compared to lcSSc. No differences in both fat and lean mass were found in the three study groups even if patients with dcSSc showed a slightly lower total body mass compared to healthy controls. Total mineral content was significantly reduced in dSSc compared to both healthy subjects and lcSSc group. Hypovitaminosis D was observed both in healthy post-menopausal women and in SSc patients, but 25OHD levels were significantly lower in dcSSc compared to lcSSc and inversely correlated with the extent of skin thickness. These results support the hypothesis that the extent of skin involvement in SSc patients could be an important factor in determining low circulating levels of 25OHD, which in turn could play a significant role in the reduction of BMD and total mineral content.
