Trends in severe outcomes in SARS-CoV-2-positive hospitalized patients with rheumatic diseases: a monocentric observational and case-control study in northern Italy.

Rheumatic disease patients are at greater risk of infection due to their disease, comorbidities, and immunosuppressive therapy. COVID-19 outcomes in this patient setting appeared to be similar to those of the general population. However, data on this topic were mainly related to small studies on a limited number of patients. Consequently, to date, this field remains poorly explored, particularly in the pre-vaccine era. This monocentric study aimed to describe the intrahospital mortality in rheumatic patients with SARS-CoV-2 consecutively hospitalized from 21 February to 31 December 2020, before anti-SARS-CoV-2 vaccine administration spread, compared with non-rheumatic patients. Of 2491 included patients, 65 [3%, median (interquartile range) age 75 (64.76-82.239 years, 65% women] were suffering from rheumatic diseases. A total of 20 deaths were reported [case fatality rate 31%, 95% confidence interval (CI): 19-42] compared with 433 deaths (19%, 95% CI: 17-20) in patients without rheumatic diseases (p=0.024). However, the rheumatic disease was not associated with a significant increase in univariate mortality hazards (hazard ratio 1.374, 95% CI: 0.876-2.154), and after adjustment (hazard ratio 1.199, 95% CI: 0.759-1.894) by age, sex and Charlson comorbidity index. The incidence of intensive care unit admission, death, and discharge in the case-control study was comparable between rheumatic and non-rheumatic patients. The presence of rheumatic diseases in SARS-CoV-2-hospitalized patients did not represent an independent risk factor for severe disease or mortality.

Sick leave request following anti-COVID-19 vaccine administration is low among healthcare workers: results from a retrospective cross-sectional monocentric study.

OBJECTIVE: Anti-COVID-19 vaccines were mainly associated with non-serious adverse events (AEs), whose prevalence was reported to be up to 70% in healthcare workers (HCWs). This may lead to sick leave requests, but this impact has never been quantified. This study aimed to investigate the absence from work among HCWs following anti-COVID-19 vaccination. Its association with age and previous COVID-19 infection was also assessed. PATIENTS AND METHODS: This is a retrospective observational cross-sectional study on administrative data about sick leave requests after anti-COVID-19 vaccination. All the HCWs employed at the Niguarda Hospital (Milan, Italy) who received the vaccine from December 27, 2020 to February 28, 2021 were included. RESULTS: In total, 4,088 HCWs received the first dose of the vaccine and 4,043 completed the vaccination cycle. After the first injection, 1.6% of HCWs requested sick leave, while after the second injection, the number of requests significantly increased (+6.1%, p<0.001). A significant increase in sick leave was detected for those who have had SARS-CoV-2 infection after the first injection (+2.3%, p<0.001). After the second dose, a significant increase in sick leave was observed in the 20-30-year-old group compared to >30 years (+3.6%, p=0.017), if HCWs without a history of SARS-CoV-2 infection were considered. CONCLUSIONS: The requests for sick leave among HCWs following the anti-COVID-19 vaccine were limited and higher after the second injection. This may help the management of the human resources when the large-scale administration of the anti-COVID-19 vaccines will involve other categories of workers.

Host factors and history of SARS-CoV-2 infection impact the reactogenicity of BNT162b2 mRNA vaccine: results from a cross-sectional survey on 7,014 workers in healthcare.

OBJECTIVE: This study aimed to improve the post-marketing surveillance on mRNA anti-SARS-CoV-2 vaccines, characterizing the adverse events (AEs) after the first dose of mRNA BNT162b vaccine. The associations between the AEs and individuals' characteristics were explored. PATIENTS AND METHODS: All adult healthcare workers at Niguarda Hospital (Milan, Italy) who were referred for the first dose of vaccine were offered to participate in a cross-sectional survey during the second-dose administration, between 18 January and 7 February 2021. All participants completed a questionnaire about age, gender, weight, height, medical history, concurrent therapies, employment status, previous diagnosis/testing for SARS-CoV-2 infection, and a list of 24 AEs (solicited AEs). The development of at least one solicited AEs was the main outcome. AEs were stratified by the presence of injection-site symptoms, systemic symptoms or both, and the differences between strata were assessed as a secondary outcome. Biometric data and reports of a previous diagnosis of SARS-CoV-2 infection were also explored, as predictors of the main outcome. RESULTS: 7,014 healthcare workers were included. An incidence of 3 per 10.000 persons for serious AEs following the first administration of the mRNA BNT162b vaccine was found. An association between the development of non-serious AEs with young age, female gender, low body mass index, and previous history of SARS-CoV-2 was described. CONCLUSIONS: This real-life study supported data on the safety profile of the BNT162b2 mRNA vaccine. Our findings on the associations between the development of non-serious AEs with some individual characteristics may help physicians and patients make educated and informed medical decisions towards anti-COVID-19 vaccination.

Ultrasound characterization of insulin induced lipohypertrophy in type 1 diabetes mellitus.

OBJECTIVE: Subcutaneous insulin absorption is one of the key factors affecting glycemic control in patients with diabetes mellitus under insulin therapy. Insulin-induced subcutaneous lipohypertrophy has been reported to impair insulin regular absorption and hence glycemic control. So far, lipohypertrophy diagnosis has only been clinical. This study aims at evaluating the possible role of ultrasound scan in the assessment of subcutaneous lipohypertrophy in patients affected by type 1 diabetes mellitus. METHODS: A pilot observational retrospective study was performed in 20 patients affected by type 1 diabetes mellitus. In these patients the areas with clinical evidence of lipohypertrophy dependent on the insulin injections were characterized by the presence of tissues that at the ultrasound scan resulted similar to fibrotic tissues (hyperechogenic) or to an interstitial edema or to fat tissues (hypoechogenic). It was utilized a multi frequency linear probe (6-18 MHz). The patients were advised to avoid insulin injections on the areas with lipohypertrophy scanned by the ultrasound and the HbA1c changes were evaluated 3 months later. RESULTS: The lipohypertrophic areas presented at least three different aspects upon ultrasound assessment: the iso-hyperechogenic one, with a predominant fibrotic component; the isoechogenic one, with "large tangles" fibrotic elements and the iso-hypoechogenic aspect with no fibrotic elements. When patients were advised to avoid insulin injections on areas with lipohypertrophy defined by ultrasound scan, 3 months after the first evaluation HbA1c had significantly improved (basal HbA1c 7.87 ± 0.56 versus 7.67 ± 0.52 3 months later, p = 0.029). No significant improvements of the HbA1c were found in the control matched group in which lipohypertrophy was only clinically valued through inspection and palpation. CONCLUSIONS: Ultrasound scan can help identify and characterize the lipohypertrophic areas and this might be useful to improve glycemic control.

The impact on disability of initial treatment with methotrexate in patients with rheumatoid arthritis: results from the MARI study.

The study aimed to assess in a population of subjects with rheumatoid arthritis (RA) treated with methotrexate (MTX) how the initial approach to the treatment influenced subsequent disability. We performed a cross-sectional analysis of data collected during the baseline visit of the MARI study, a multicenter observational study on patients with RA on treatment with MTX for at least 12 months. Subjects who fulfilled the Health Assessment Questionnaire (HAQ) were included in the evaluation. For every patient we retrospectively evaluated the disease duration, the duration of symptoms before the diagnosis, the time elapsed before first MTX treatment, the initial MTX dose, and the concomitant medications in the first six months of therapy. Disability was defined as a DI-HAQ score ≥1. The study population included 1015 subjects. Patients with a DI-HAQ score ≥1 had a longer duration of symptoms before diagnosis, a higher delay in treatment initiation, a lower initial dose of MTX and a more frequent co-treatment with symptomatic drugs. Disability was found less frequently in subjects treated with other concomitant disease modifying anti-rheumatic drugs (DMARDs) but not with biological agents. Logistic regression analysis identified as significant predictors of disability: older age, female sex, a longer time to complete diagnosis, a delay in starting MTX treatment higher than 6 months, and a concomitant treatment with symptomatic drugs, while a combination therapy with other DMARDs was associated with a lower risk of disability. A late diagnosis and a delay in starting a treatment with MTX are associated with poorer functional outcomes in patients with RA.

Suboptimal methotrexate use in rheumatoid arthritis patients in Italy: the MARI study.

OBJECTIVES: Methotrexate (MTX) is the first choice in the treatment of rheumatoid arthritis (RA), but the doses and regimens vary significantly. For this purpose, we conducted an observational study on the use of MTX for RA in Italy (MARI study). METHODS: The MARI study included 1,327 RA patients on MTX treatment for at least 12 months, at 60 Italian rheumatology units. Concomitant medications with corticosteroids, other DMARDs or biological therapies were recorded. The clinical assessment included the Disease Activity Score 28 (DAS28) and the serological positivity for the rheumatoid factor or for the anti-citrullinated protein antibodies. RESULTS: The included patients were treated with either oral (n=288) or parenteral (n=1039) MTX. Only 15.5% of the total number of the patients was on adequate MTX dose (i.e. ≥ 15 mg for the oral route of administration and >12 mg for the parenteral one). The initially established MTX dose was modified in 37.1% of the patients, for intolerance or clinical criteria. A DAS28 remission (DAS28 <2.6) was observed only in 58.5% of the cases, while 52.9% of the patients still presenting an active form of the disease were on suboptimal doses of MTX. CONCLUSIONS: The weekly dose of MTX prescribed for the treatment of RA is often suboptimal, even in conditions of inadequate control of the disease activity. The recommendations for the use of MTX in RA patients should take into account the efficacy and tolerability data derived from its use in real clinical practice.

MANAGEMENT OF PSORIATIC ARTHRITIS: SHOULD THE INTERACTION BETWEEN DERMATOLOGISTS AND RHEUMATOLOGISTS IN CLINICAL PRACTICE BE INTENSIFIED?

Psoriatic arthritis is an inflammatory seronegative spondyloarthropathy that occurs in approximately 25% of patients with psoriasis and is a progressive and severely disabling disease. Most patients have had psoriasis for several years before the development of arthritis or develop the joint and skin condition simultaneously. Given the absence of specific diagnostic test for psoriatic arthritis, clinical findings remain the standard criteria for the diagnosis. Patients with psoriasis presenting to the dermatologist for management of their skin disease may have joint symptoms related or not to psoriatic arthritis and similarly arthritic patients presenting to a rheumatologist for the management of psoriatic arthritis may have skin lesions related or not to psoriasis. In this paper an expert panel of specialist belonging to the “Associazione Dermatologi Ospedalieri Italiani” (ADOI) and “Collegio dei Reumatologi Ospedalieri Italiani” (CROI) analysed the international literature and scientific recommendations and also investigated the Italian setting. It has been demonstrated in the literature that a multidisciplinary clinical setting may benefit patients with psoriatic arthritis from both diagnostic and therapeutic points of view. The comparative analysis of the Italian clinical records used by ADOI and CROI have highlighted some substantial differences. Collaboration between the dermatologist and rheumatologist allows for a more complete appreciation of the overall skin and musculoskeletal disease burden, and subsequently leads to a more comprehensive treatment approach.

Safety of rituximab in the routine treatment of rheumatoid arthritis in Italy in patients refractory to anti-TNFa drugs: results from the observational retrospective-prospective RUBINO study.

The paper reports the results from the observational retrospective-prospective RUBINO study conducted in Italy to assess the safety of rituximab in the treatment of rheumatoid arthritis (RA) in routine clinical practice. The percentage of patients who manifested at least one grade 3 or 4 adverse event (AE) assessed by the Common Terminology Criteria for Adverse Events version 3.0 (CTCAE v.3) during the observation period (primary objective) was evaluated. The percentage of patients manifesting a severe AE (SAE), clinical response to rituximab treatment, clinical remission according to disease activity score for 28 joints (DAS28) criteria, markers of disease and quality of life were also assessed. Fifty-three Italian rheumatology centers took part in the study. Patients with a diagnosis of RA and inadequate response to anti-tumor necrosis factor b (anti-TNFa) drugs were enrolled. Participating patients had previously received at least one cycle of rituximab, and treatment was still ongoing at the time of recruitment. Out of 205 patients enrolled, 60% manifested no form of AE, 14.2% had at least one grade 3 or 4 AE, and 11.2% patients reported an SAE. The overall percentage of patients manifesting AEs (40%) was lower compared to the DANCER (81% and 85%), REFLEX (85%) and RESET (85% and 69%) studies, but higher than that observed in the CERERRA registry (from 10.2% to 13.9%). This difference may be due to the shorter observation period applied in the CERERRA registry (only 12 months) compared to the RUBINO study (up to 3 years). All parameters of RA activity (erythrocyte sedimentation rate, C-reactive protein, health assessment questionnaire score, DAS28) improved significantly during the study.

Ultrasound imaging for the rheumatologist. XVII. Role of colour Doppler and power Doppler.

The use of Doppler ultrasound in rheumatology has grown in recent years. This is partly due to the increasing number of rheumatologists who perform US in their daily clinical practise and also to the technological advances of US systems. Both colour Doppler and power Doppler are used to evaluate the degree of intra- and peri-articular soft tissue inflammation. Moreover, Doppler US has been found to be of help in the assessment of vascular pathologies such as the vasculitides. In this review we provide an update of the data regarding the use of colour Doppler and power Doppler in rheumatology.

Ultrasound imaging for the rheumatologist. XVI. Ultrasound-guided procedures.

Ultrasonography (US) has proved to be a useful tool for the clinical evaluation of patients with rheumatic diseases. It is also recognised as a useful imaging technique in interventional radiology. In the last few years, a number of rheumatologists have also described and advocated the use of US guidance in joint and soft tissue aspiration and injection technique in clinical practice. Moreover, US-guided synovial biopsy methods have been proposed as an interesting and reliable method for the histopathological assessment of small and large joint sinovium. The present review provides an update of the available data regarding the use of US in interventional procedures in clinical rheumatology.

Ultrasound imaging for the rheumatologist XIV. Ultrasound imaging in connective tissue diseases.

Ultrasound (US) role is becoming more and more relevant in the assessment of rheumatic diseases but there are still some almost unexplored fields and, surely, one of these is represented by the great family of connective tissue diseases (CTD). In this review we provide an update of the available data regarding some applications of US in CTD. Besides an overview of the role of US in their musculoskeletal involvement, we will report data on the use of US in the evaluation of skin and lung in systemic sclerosis and of salivary glands in Sjögren's syndrome. US assessment of heart, kidney or vascular involvement in CTD will not be the subjects of this paper.

Ultrasound imaging for the rheumatologist. XV. Ultrasound imaging in vasculitis.

Over the last few years, a large number of studies have emphasized the fundamental role of ultrasonography (US) in the clinical evaluation of patients affected by rheumatic disorders. However, not all rheumatic diseases have been studied by US. To date, very few reports exist on the use of US in the assessment of articular, periarticular structures and blood vessels in vasculitis. In this review we provide an overview of the current data regarding the role of US in vasculitis. Sonographic evaluation of cardiac or renal involvement in these disorders will not be covered.

Ultrasound imaging for the rheumatologist. XIII. New trends. Three-dimensional ultrasonography.

Despite its indubitable potential, ultrasonography still has limited diffusion in rheumatology related principally to the image acquisition process due to at least five main factors: the steep learning curve, lack of standardisation of the technique, intra- and inter-observer variability, time consumption and the high initial cost of top quality sonographic equipment. Of all these barriers, the first four are undoubtedly the most difficult to overcome. This review discusses the available evidence supporting the potential of three-dimensional ultrasound with high-frequency volumetric probe to overcome the first four barriers. The challenge to three-dimensional ultrasound is to prove itself to be a method that requires no particular skills that can be mastered in just a few minutes and is not operator-dependant [corrected]

Ultrasound imaging for the rheumatologist. XVIII. Ultrasound measurements.

One of the largest challenges to the field of musculoskeletal ultrasonography is attempting to accurately quantify the changes seen in chronic arthritis. With advances in ultrasound technology, researchers have been increasingly exploring ways of more accurately assessing these changes and attempting to reach consensus with agreed scoring systems. This review presents the main scoring systems developed for quantifying sonographic findings indicative of synovitis and joint damage in patients with rheumatoid arthritis. Further investigation is required to attain international consensus on such scoring systems and to evaluate their impact on therapeutic decision-making.

Prevalence of undiagnosed autoimmune rheumatic diseases in the first trimester of pregnancy. Results of a two-steps strategy using a self-administered questionnaire and autoantibody testing.

OBJECTIVE: To evaluate the prevalence of undiagnosed rheumatic diseases in the first trimester of pregnancy. DESIGN: We screened for rheumatic diseases in 1210 consecutive pregnant women during the first trimester of pregnancy using a 10-item questionnaire. SETTING: A university hospital in northern Italy. POPULATION: One hundred and thirty-seven (11.3%) women who answered positively to at least one question constituted the cases and were compared with 107 negative controls. METHODS: Cases and controls were tested for rheumatic autoantibodies (antinuclear antibody, anti-double-stranded DNA, anti-extractable nuclear antigen, anticardiolipin antibody, anti-beta2-glycoprotein I antibodies and lupus anticoagulant) and were evaluated by a rheumatologist for a definite diagnosis of rheumatic disease. MAIN OUTCOME MEASURES: Prevalence of undiagnosed rheumatic disease in the first trimester of pregnancy. RESULTS: The overall rate of positivity to the antibodies tested was 43.1% (59/137) among cases and 9.3% (10/107) in the controls (P < 0.001). A definitive diagnosis of rheumatic disease was made in 35 cases (25.5%) and in none of the controls (P <0.001). In stepwise logistic regression analysis, photosensitivity (adjusted OR 5.72; 95% CI 2.38-13.8), erythema or malar rash (adjusted OR 3.91; 95% CI 1.53-10) and history of two or more miscarriages (adjusted OR 5.6; 95% CI 1.55-20.6) were independent predictors of a definitive diagnosis of rheumatic disease (area under receiving operator curve = 0.814; 95% CI 0.76-0.86). Birthweight was lower (3180 g +/- 475 compared with 3340 g +/- 452, P= 0.008), and overall serious pregnancy complications (miscarriage, fetal growth restriction, delivery before 34 weeks of pregnancy and severe pre-eclampsia) were higher among cases (12/137) than controls (2/107) (adjusted OR 5.60; 95% CI 1.29-24.3; P= 0.021). CONCLUSIONS: A two-step screening process with a self-administered questionnaire proved to be a useful method to screen for undiagnosed rheumatic diseases during the first trimester of pregnancy.

[Simultaneous ultrasonography and arthroscopy for the study of the joint environment: indications and limits]. / Ecografia e artroscopia in contemporanea per lo studio dell'ambiente articolare: indicazioni e limiti.

Arthroscopy is a mini-invasive technique that allows the direct observation of the joint cavity and the execution of diagnostic and therapeutic procedures; arthroscopy needs a very long learning-time curve as well as dedicated spaces and instruments. Ultrasonography is an imaging technique that enables to perform an immediate extension of the standard physical examination. The opportunity to visualize soft tissues, to obtain multiplanar and dynamic images in real time makes this practice easy repeatable at low costs. Ultrasonography allows to detect a variety of changes during inflammatory processes. The wide experience in arthroscopy of rheumatic patients acquired through the years by our team at the G. Pini Institute led us to study in vivo, during arthroscopy, the correspondence between arthroscopic and ultrasonographic images. Up to now three knee arthroscopies have been conducted with the double equipment (ultrasonographic and arthroscopic devices) in operating room. In our experience, the combination of the two methods in operating room may improve the validation of ultrasonography with arthroscopy as gold standard, helps to train the ultrasonographer to give immediate answers in order to clear the doubts aroused by ultrasonographic images; it also allows the arthroscopist to visualize the deeper layers of the synovial membrane making double guided targeted biopsies possible. Limits are the complexity of the procedure (instruments, operators, spaces, training of the doctors), the loose of power-doppler signal with the blood tourniquet and the always difficult evaluation of cartilage.

[Milwaukee shoulder syndrome (apatite associated destructive arthritis): therapeutic aspects]. / Milwaukee shoulder syndrome (artropatia destruente apatite-associata): aspetti terapeutici.

Milwaukee shoulder is a well defined clinical entity that can be observed in particular in older women. It is a destructive arthropathy associated with the deposition of calcium pyrophosphate dihydrate crystals, characterized by the presence of large amount of synovial fluid and a complete tear of the rotator cuff. Clinical features include pain, swelling and progressive functional impairment. The first-line treatment include the use of analgesic drugs and repeated arthrocentesis followed by intra-articular steroid administration; closed-needle tidal irrigation has been reported to be useful. In late phase we can observe narrowing of the acromion-humeral and of the gleno-humeral joint and progressive degenerative changes at the humeral head, leading to almost complete functional impairment. In these cases a surgical approach with total shoulder arthroplasty may be considered.
