Objectives

The aim of this study is to examine how gene mutation diversity and disease severity affect physical capacity and quality of life in children/adolescents with Familial Mediterranean Fever (FMF).

Methods

Eighty children/adolescents (42 female, 38 male) diagnosed with FMF according to Tell-Hashomer diagnostic criteria were included in this study. Disease severity score (PRAS), running speed and agility and strength subtests of Bruininks-Oseretsky Test of Motor Proficiency Second Edition Short Form (BOT-2 SF), Physical Activity Questionnaire, Pediatric Quality of Life Inventory 3.0 Arthritis Module (PedsQL) was used for evaluation. Participants were divided into 2 groups as M694V and other mutations according to MEFV gene mutation and were divided into 3 groups as mild, moderate and severe according to PRAS.

Results

When the data were compared between groups; in terms of gene mutation, a significant difference was observed in treatment subtest of PedsQL-parent form in favor of the M694V gene mutation group (p < 0.05). In terms of PRAS, significant difference was seen in the pain, treatment subtests and total score of the PedsQL-child form, and in the pain, treatment, worry subtests and total score of the PedsQL-parent form in favor of the mild group (p < 0.05).

Conclusions

MEFV gene mutations in children and adolescents with FMF did not differ on physical capacity and quality of life. PRAS was not effective on physical parameters, but quality of life decreased as the severity score increased. Encouraging children/adolescents with FMF to participate in physical activity and to support them psychosocially can be important to improve their quality of life.

Background

The peripheral microangiopathy may be well evaluated and studied by nailfold capillaroscopy (NFC) which is a safe and non-invasive technique. NFC has been reported to have both diagnostic and prognostic values in patients presenting with Raynaud's phenomenon.

Objective

The overarching objective of this work was to make a consensus on what domains should be included in a capillaroscopy report and that it can be used in daily clinical practice and clinical research in the area of rheumatology.

Methods

A Delphi questionnaire was developed regarding capillaroscopy report from a literature review and expert consensus. The first Delphi round included 14 core areas, its 18 domains with 50 subdomains, derived from a systematic literature review. The level of evidence was determined for each core set using the Oxford Centre for Evidence-based Medicine (CEBM) system. Nine response categories have been set per each item ranging between 1 and 9. Round 2, aimed to reach preliminary consensus “in” or “out” for domains. It included all items that were rated “critical” by at least 80% of the participants as well as any new domains proposed in round 1.

Results

The participants to the first, and second round were 11 experts. Fourteen domains were discussed in the two rounds. At the end of the survey, the final report template of NFC in rheumatology reached a consensus.

Conclusion

A nailfold capillaroscopy report template has been developed by this study, based on outcomes of a Delphi process, by international participants panel. All domains met the 80% voting threshold set in this work. The reporting template can be used for both clinical research as well as day to day practice to provide guidance and standardize the NFC reporting.

The Spanish Society of Rheumatology (SER) brings together the majority of Spain's rheumatologists and, among the many services it offers its members, has a Research Unit (RU). This unit provides methodological support to SER members in clinical and epidemiological research, coordinates and carries out research projects, designs and maintains large patient databases, develops qualitative research projects and produces evidence-based medicine (EBM) documents. Through this last activity, the RU of the SER produces clinical practice guidelines and recommendation documents on topics relevant to rheumatology that meet the most demanding methodological standards. The aim of this article is to describe the management process and methodology followed by the UI of the SER to identify the topics of its EBM documents and how it executes and develops its guidelines and recommendations.

Objectives

Osteoarthritis (OA) is a complex multifactorial disease. The association of knee OA risk with ACE gene rs4343 polymorphism, gene environment synergistic effect, and angiotensin II serum level has not been previously examined. Therefore, we investigate the ACE gene rs4343 polymorphism in knee OA, and its association with severity of knee OA, and angiotensin II serum level.

Methods

Using a case–control design, we recruited 200 subjects (100 cases and 100 controls) and all were subjected to genotyping of rs4343 SNP by real-time polymerase chain reaction and assay of serum angiotensin II level by ELISA.

Results

G containing genotypes (AG and GG) and G allele frequencies of the ACE rs4343 polymorphism were significantly higher in the case group than that in the control group. There was significant association between ACE rs4343 genotypes and risk of knee OA under the following genetic inheritance models: GG vs. AA (P = 0.003), AA vs. GG/AG (P = 0.014), AG/AA vs. GG (P = 0.037), and G vs. A (P < 0.001). Stratified analyses showed ACE rs4343 polymorphism was evidently associated with a significantly increased risk of knee OA among those had BMI ≥ 25% (adjusted OR = 3.016; 95% CI 1.052–8.648; P = 0.040). Additionally, knee OA patients with GG genotype had greater knee specific WOMAC index, Kellgren score, and serum angiotensin II level than those with AA or GA genotypes.

Conclusion

The investigated polymorphism in the ACE gene rs4343 may reflect the risk and severity of knee OA in the Egyptian population, particularly with the GG genotype. The interaction between ACE gene rs4343 polymorphism and obesity further increased the risk of knee OA. Moreover, the higher angiotensin II level may be involved in the pathogenesis of knee OA.

Introduction

Biological disease-modifying antirheumatic drugs (bDMARD) have improved the clinical course and quality of life of patients with rheumatoid arthritis (RA). However, some patients failed to respond or have an insufficient response to bDMARD early in the course of the treatment.

Objectives

To determine the percentage of RA patients who need to switch due to ineffectiveness in the first year of treatment and to identify specific baseline features as possible predictors of switch due to ineffectiveness in the first year of treatment.

Materials and methods

An observational retrospective study was conducted with patients with RA that started their first bDMARD. Demographic data, disease characteristics, disease activity data scores, laboratory parameters and treatment at baseline were collected. The proportion of patients who failed to respond and who switched to another bDMARD in the first year of treatment was calculated.

Results

A total of 437 (364 females, 83.3%) patients with RA were included. The majority of these patients started an anti-TNF-α agent (n = 315, 72.1%). Forty-eight (11.0%) patients failed to respond to the bDMARD in the first year of treatment. There were significantly more current or former smokers (p = 0.030), with a history of depression (p = 0.003) and positive for RF at baseline (p = 0.014) in the switch group.

In the multivariate analysis, anti-TNF-α agents use (OR 8.3, 95% CI 2.4–28.8, p = 0.001), tobacco exposure (OR 2.3, 95% CI 1.1–4.8, p = 0.02) and history of depression (OR 3.1, 95% CI 1.3–7.7) seem to predict the need to switch in the first year of treatment due to ineffectiveness.

Discussion and conclusion

In our study, tobacco exposure and depression appear to be modifiable risk factors associated with early switching due to ineffectiveness. Addressing these factors in daily clinical practice is crucial to enhance the overall response to therapy and improve the well-being of patients.

Objective

To assess the prevalence of systemic and organ-specific autoimmunity among individuals with human inborn errors of immunity (IEI).

Methods

Retrospective study. We recorded demographic variables, type of immunodeficiency, and systemic and organ specific autoimmunity.

Results

We included 48 patients (54.1% men) with mean age of 32.1 years. The most common IEIs included combined immunodeficiency with syndromic features (31.2%) and predominantly antibody deficiency (20.1%). We observed autoimmunity in 15 patients (31.2%): 12 organ-specific autoimmunity and 5 systemic autoimmunity, not mutually exclusive groups. Organ-specific autoimmunity preceded the onset of IEI in 5 patients, was concurrent in one patient, and developed after the diagnosis of IEI in 6 cases. From the systemic autoimmunity group, we observed polyarteritis nodosa (n = 2), antiphospholipid syndrome (APS) (n = 2), and overlap of limited systemic sclerosis/APS/Sjögren's syndrome (n = 1), and in all cases, this occurred after the IEI diagnosis.

Conclusion

Our findings confirm the coexistence of autoimmunity and IEI. This overlap may be attributed to B and T cell disorders, as well as potential alterations in the microbiota in these patients.

Introduction

Systemic sclerosis (SSc) is characterized by progressive fibrosis of the skin and internal organs, microvascular damage and cellular and humoral immunity abnormalities. Microvascular damage can be easily detected through nailfold videocapillaroscopy (NVC).

Materials and methods

A retrospective study of patients with SSc and a NVC performed within the first 6 months after diagnosis was conducted. Visceral involvement in the first 3 years of the disease and NVC findings were collected. The severity of microvascular damage was classified into four categories, according to the worsening of the NVC patterns. The severity of organ involvement was assessed by the disease severity scale of Medsger for each organ and as a global measure of disease severity, the simple summation was used.

Results

A total of 86 patients with SSc were included. A moderate correlation was found between the severity of microvascular damage and the global measure of disease severity (r = 0.55, p < 0.001), the severity of peripheral vascular involvement (r = 0.43, p < 0.001) and the severity of skin involvement (r = 0.34, p = 0.001).

The presence of a late scleroderma pattern in NVC were predictive in univariate analysis of digital ulcers (OR 6.03, 95% CI 1.52–23.86, p = 0.01), muscular involvement (OR 13.09, 95% CI 1.09–156.78, p = 0.04), calcinosis (OR 27.22, 95% CI 5.56–133.33, p < 0.001) and worse global disease severity score (OR 1.67, 95% CI 1.17–2.38, p = 0.005). Multivariate analysis adjusted for disease duration and gender confirmed late pattern as an independent predictor of calcinosis (OR 42.89, 95% CI 5.53–332.85, p < 0.001).

Discussion and conclusion

In this study, the worsening of NVC pattern in SSc was associated with the overall disease severity, the severity of peripheral vascular involvement and extension of skin involvement. This study highlights the importance of NVC as a prognostic tool and a possible predictor of systemic visceral involvement.

Background

This study investigates the association between inflammatory myopathies (IM), and their correlation with cancer. There are several potential causes behind the association of cancer and inflammatory myopathies. The positivity of specific antibodies for myositis plays a significant role. Our objective is to describe cancer and inflammatory myopathies in Colombia, focusing on demographics, clinical characteristics, and laboratory data.

Methods

We retrospectively analyzed 112 IM patients diagnosed at Fundación Valle del Lili in Cali, Colombia, the cases met the EULAR/ACR criteria. Data included demographics, clinical signs, laboratory findings, and malignancy. Malignancy associations were explored using logistic regression. The survival analysis was assessed using Kaplan–Meier curves and the Log-Rank test.

Results

Dermatomyositis was the most common subtype (45.5%), with a female predominance (66.1%). Cancer diagnosis occurred in 11.6% of cases, predominantly thyroid cancer. The median time from myopathy onset to cancer diagnosis was 11 months, with 75% of cases within the first year. Bivariate analysis indicated associations between cancer and age, Gottron's papules, digital ulcers, and heliotrope rash. However, multivariate analysis identified age as the only significant malignancy risk factor. Survival analysis showed better rates in younger patients.

Conclusion

This study provides into the link between IM and cancer in the Colombian population. Thyroid cancer predominated, with a slightly higher proportion of female cancer diagnoses. Age emerged as a significant risk factor for malignancy. Understanding this association is crucial for early detection and improving patient outcomes related to IM-associated malignancies.

An inadequate biomarker validation can affect many patients' diagnosis, treatment, and follow-up. Therefore, special interest should be placed on performing these analyses correctly so that biomarkers can be applicable to patients and evidence of their clinical usefulness can be generated. A methodological work on the concept of biomarkers is presented, as well as the difficulties associated with the methodological approach to their development, validation, and implementation in clinical practice.
