Rheumatoid Nodules Predating Seroconversion and Rheumatoid Arthritis: An Uncommon Case Report

Rheumatoid nodulosis is a benign condition associated with mild or no arthritis. Differently from classical rheumatoid nodules, which are relatively common in patients with long-standing rheumatoid arthritis, particularly in rheumatoid factor (RF)-positive patients, rheumatoid nodulosis may rarely precede arthritis onset and even seroconversion. We describe the clinical course of a patient with isolated painful rheumatoid nodules, who subsequently experienced RF and anti-citrullinated protein antibodies (ACPA) seroconversion and finally developed overt rheumatoid arthritis. This case should raise clinical awareness to consider rheumatoid nodulosis as a possible diagnosis even in the absence of arthritis and of RF positivity, whenever facing with isolated subcutaneous nodules

Olive Oil and Nuts in Rheumatoid Arthritis Disease Activity

Few observational studies investigated the relationship between single food groups and disease activity in rheumatoid arthritis (RA). Within a recent Italian cross-sectional study (365 patients, median age: 58.46 years, 78.63% females), we focused on two food groups, olive oil and nuts, representing vegetable sources of fatty acids. Disease activity was measured with Disease Activity Score on 28 joints based on C-reactive protein (DAS28-CRP) and the Simplified Disease Activity Index (SDAI). Robust linear and logistic regression models included tertile-based consumption categories of each food group and several confounders. Stratified analyses were performed by disease severity or duration. Higher consumption of both food groups exerted a favorable effect on disease activity, significant only for olive oil (Beta: -0.33, p-value: 0.03) in the linear regression on the overall sample. This favorable effect was stronger in the more severe or long-standing forms of RA (p-value for heterogeneity <0.05, especially for disease severity). Significant ORs were as low as ~0.30 for both food groups, strata (i.e., more severe and long-standing RA), and disease activity measures. Mean DAS28-CRP significantly decreased by ~0.70 for olive oil and ~0.55 for nuts in the two strata; mean SDAI significantly decreased by 3.30 or more for olive oil in the two strata. Globally, the beta coefficients doubled, and the ORs halved (in absolute values) for both food groups, reaching significance in 12 of the 16 available models fitted to the more severe or long-standing RA strata. More compromised forms of RA may benefit from increasing consumption of olive oil, olives, and nuts

The patient experience of Raynaud's phenomenon in systemic sclerosis

RP is the most common manifestation of SSc and a major cause of disease-related morbidity. This review provides a detailed appraisal of the patient experience of SSc-RP and potential implications for disease classification, patient-reported outcome instrument development and SSc-RP clinical trial design. The review explores the clinical features of SSc-RP, the severity and burden of SSc-RP symptoms and the impact of SSc-RP on function, work and social participation, body image dissatisfaction and health-related quality of life in SSc. Where management of SSc-RP is concerned, the review focuses on the 'patient experience' of interventions for SSc-RP, examining geographic variation in clinical practice and potential barriers to the adoption of treatment recommendations concerning best-practice management of SSc-RP. Knowledge gaps are highlighted that could form the focus of future research. A more thorough understanding of the patient experience could support the development of novel reported outcome instruments for assessing SSc-RP

The crucial questions on synovial biopsy: when, why, who, what, where, and how?

In the majority of joint diseases, changes in the organization of the synovial architecture appear early. Synovial tissue analysis might provide useful information for the diagnosis, especially in atypical and rare joint disorders, and might have a value in case of undifferentiated inflammatory arthritis, by improving disease classification. After patient selection, it is crucial to address the dialogue between the clinician and the pathologist for adequately handling the sample, allowing identifying histological patterns depending on the clinical suspicion. Moreover, synovial tissue analysis gives insight into disease progression helping patient stratification, by working as an actionable and mechanistic biomarker. Finally, it contributes to an understanding of joint disease pathogenesis holding promise for identifying new synovial biomarkers and developing new therapeutic strategies. All of the indications mentioned above are not so far from being investigated in everyday clinical practice in tertiary referral hospitals, thanks to the great feasibility and safety of old and more recent techniques such as ultrasound-guided needle biopsy and needle arthroscopy. Thus, even in rheumatology clinical practice, pathobiology might be a key component in the management and treatment decision-making process. This review aims to examine some essential and crucial points regarding why, when, where, and how to perform a synovial biopsy in clinical practice and research settings and what information you might expect after a proper patient selection

Qualitative and quantitative analysis of gingival microvessels by capillaroscopy in healthy subjects

Gingiva is composed by attached gingiva and free gingiva that are separated by free gingival line. Attached gingiva covers the alveolar bone and adheres to the bone and root surface by fibres. Free gingiva ends with the gingival margin and in clinical practice it can be displaced from the tooth surface to locate the prosthetic margin. Capillaroscopy allows to take microphotographs of the microvessels and to observe their abnormalities in autoimmune rheumatic diseases (1). Aim of this study was to analyse microvessels of the attached gingiva, free gingiva line and free gingiva by means of capillaroscopy. In correspondence of upper incisors of 12 young healthy volunteers, after placement of liquid vaseline, microphotographs (x200) were taken at level of the free gingiva and 2-3 mm more apically within the attached gingiva. Capillaries structure and organization were evaluated in the three areas of interest. In 10 randomly selected microphotographs of the attached gingiva, the amount and percentage of microvessels per mm2 were also calculated. For each subject, two analyses were performed at 3 weeks of distance for repeatability assessment. At the observation, in attached gingiva vessels appeared as tortuous capillary loops perpendicular to the epithelial surface. At level of free gingival line vessels get linear and parallel to the arch of gingival margin. In free gingiva capillaries run superficially and parallel to the epithelial surface, toward the margin and fell back with a loop on the tooth side. At the quantitative analysis, the method resulted repeatable (Wilcoxon signed-rank test, p>0.05). A mean of 49.8 (± 9.5) microvessels for mm2 was found. Capillaries represented the 10.3% (±3.5) of the attached gingiva. Capillaroscopy is a non-invasive repeatable method to observe gingival capillaries. This method may be proposed in clinical practice to detect and monitor changes or abnormalities after placement of prosthetic margins

Does Pizza Consumption Favor an Improved Disease Activity in Rheumatoid Arthritis?

To our knowledge, no studies so far have investigated the role of pizza and its ingredients in modulating disease activity in rheumatoid arthritis (RA). We assessed this question via a recent cross-sectional study including 365 participants from Italy, the birthplace of pizza. Multiple robust linear and logistic regression models were fitted with the tertile consumption categories of each available pizza-related food item/group (i.e., pizza, refined grains, mozzarella cheese, and olive oil) as independent variables, and each available RA activity measure (i.e., the Disease Activity Score on 28 joints with C-reactive protein (DAS28-CRP), and the Simplified Disease Activity Index (SDAI)) as the dependent variable. Stratified analyses were carried out according to the disease severity or duration. Participants eating half a pizza >1 time/week (vs. ≤2 times/month) reported beneficial effects on disease activity, with the significant reductions of ~70% (overall analysis), and 80% (the more severe stratum), and the significant beta coefficients of −0.70 for the DAS28-CRP, and −3.6 for the SDAI (overall analysis) and of −1.10 and −5.30 (in long-standing and more severe RA, respectively). Among the pizza-related food items/groups, mozzarella cheese and olive oil showed beneficial effects, especially in the more severe stratum. Future cohort studies are needed to confirm this beneficial effect of pizza and related food items/groups on RA disease activity

Patient-reported outcome instruments for assessing Raynaud’s phenomenon in systemic sclerosis:A SCTC vascular working group report

The episodic nature of Raynaud’s phenomenon in systemic sclerosis has led to a reliance on patient-reported outcome instruments such as the Raynaud’s Condition Score diary. Little is known about the utilization in routine clinical practice and health professional attitudes toward existing patient-reported outcome instruments for assessing systemic sclerosis- Raynaud’s phenomenon. Members of the Scleroderma Clinical Trials Consortium Vascular Working Group (n = 28) were invited to participate in a survey gauging attitudes toward the Raynaud’s Condition Score diary and the perceived need for novel patient-reported outcome instruments for assessing patient-reported outcome. Nineteen Scleroderma Clinical Trials Consortium Vascular Working Group members (68% response rate) from academic units based in North America (n = 9), Europe (n = 8), South America (n = 1) and Australasia (n = 1) took part in the survey. There was broad consensus that Raynaud’s Condition Score diary returns could be influenced by factors including seasonal variation in weather, efforts made by patients to avoid or ameliorate attacks of Raynaud’s phenomenon, habituation to Raynaud’s phenomenon symptoms, evolution of Raynaud’s phenomenon symptom characteristics with progressive obliterative microangiopathy, patient-coping strategies, respondent burden and placebo effect. There was consensus that limitations of the Raynaud’s Condition Score diary might be a barrier to drug development (79% of respondents agree/strongly agree) and that a novel patient-reported outcome instrument for assessing systemic sclerosis-Raynaud’s phenomenon should be developed with the input of both clinicians and patients (84% agree/strongly agree). Perceived potential limitations of the Raynaud’s Condition Score diary have been identified along with concerns that such factors might impede drug development programs for systemic sclerosis-Raynaud’s phenomenon. There is support within the systemic sclerosis community for the development of a novel patient-reported outcome instrument for assessing systemic sclerosis-Raynaud’s phenomenon.</p

Patient-reported outcome instruments for assessing Raynaud’s phenomenon in systemic sclerosis:A SCTC vascular working group report

The episodic nature of Raynaud's phenomenon (RP) in systemic sclerosis (SSc) has led to a reliance on patient-reported outcome (PRO) instruments such as the Raynaud's Condition Score (RCS) diary. Little is known about the utilisation in routine clinical practice and health professional attitudes towards existing PRO instruments for assessing SSc-RP. Members of the Scleroderma Clinical Trials Consortium Vascular Working Group (SCTC-VWG, n=28) were invited to participate in a survey gauging attitudes towards the RCS diary and the perceived need for novel PRO instruments for assessing SSc-RP. Nineteen SCTC-VWG members (68% response rate) from academic units based in North America (n=9), Europe (n=8), South America (n=1) and Australasia (n=1) took part in the survey. There was broad consensus that RCS diary returns could be influenced by factors including seasonal variation in weather, efforts made by patients to avoid or ameliorate attacks of RP, habituation to RP symptoms, evolution of RP symptom characteristics with progressive obliterative microangiopathy, patient coping strategies, respondent burden and placebo effect. There was consensus that limitations of the RCS diary might be a barrier to drug development (79% of respondents agree/strongly agree) and that a novel PRO instrument for assessing SSc-RP should be developed with the input of both clinicians and patients (84% agree/strongly agree). Perceived potential limitations of the RCS diary have been identified along with concerns that such factors might impede drug development programs for SSc-RP.
