RESUMO

OBJECTIVE: Rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (anti-CCP) are commonly used for diagnosis of rheumatoid arthritis (RA), although other rheumatic diseases with arthritis can test positive. This study aimed to determine the cutoff values for RF and anti-CCP with the best diagnostic performance in a sample of patients with RA, compared with other rheumatic diseases. METHODS: This was a descriptive, prospective study. EUROINMMUN enzyme-linked immunosorbent assays for RF isotypes immunoglobulin (Ig) A (IgA), IgG and IgM and third-generation assay IgG for anti-CCP were used in serum samples of patients with RA, other rheumatic diseases and healthy subjects. The cutoff with the best diagnostic performance was determined by the Youden Index and receiver operating characteristic analysis Results: Three hundred and thirty-two serum samples were analysed. The cutoffs proposed in our population were for RF in RA patients versus other rheumatic diseases, and healthy subjects IgM 135 IU/mL, for each disease, compared with RA, were psoriatic arthritis (Psa) IgA 47.2 IU/mL, clinically suspicious arthralgia (CSA) IgA 39.5 IU/mL, primary Sjögren's syndrome (pSS) IgM 180.6 IU/mL, systemic lupus erythematosus (SLE) IgA 42.6 IU/mL, primary fibromyalgia (pFM) IgM 68.6 IU/mL, osteoarthritis (OA) IgM 48 IU/mL, gout IgM 117 IU/mL and healthy IgM 16.3 IU/mL. For anti-CCP, in RA patients versus other rheumatic diseases, and healthy subjects 6.95 IU/mL, for each disease, compared with RA, were Psa 6.8 IU/mL, CSA 9.95 IU/mL, pSS 20.7 IU/mL, SLE 6 IU /mL, pFM 11.8 IU/mL, OA 11.9 IU/mL, gout 5 IU/mL and healthy 5 IU/mL. CONCLUSION: Irrespective of the manufacturer's suggested cutoff, the RA versus differential diagnosis cutoffs must be considered.

RESUMO

Syndemics are a framework that documents health inequities and vulnerabilities in populations with rheumatic diseases. Compared with other approaches, syndemics are able to conjunctly consider epidemiological, biological, sociodemographic and economic factors, and their interactions. OBJECTIVE: To estimate health inequity and vulnerability among Indigenous and non-Indigenous populations with rheumatic and musculoskeletal diseases (RMD) in Latin America using the syndemic approach. DESIGN: This is a secondary analysis of a previously published large-scale study on the prevalence of RMD. SETTING: Studies carried out in five Latin American countries (Argentina, Colombia, Ecuador, Mexico and Venezuela). Health inequity and vulnerability in RMD were identified through a syndemic approach using network and cluster analysis. PARTICIPANTS: A total of 44 560 individuals were studied: 29.78% self-identified as Indigenous, 60.92% were female, the mean age was 43.25 years. Twenty clusters were identified in the Indigenous population and 17 in the non-Indigenous population. RESULTS: The variables associated with RMD among Indigenous populations were rurality, public health system, high joint biomechanical stress, greater pain, disability and alcoholism; and among non-Indigenous people they were being a woman, urban origin, older age, private health system, joint biomechanical stress, greater pain and disability. We identified different health inequities among patients with RMD (ie, lower educational attainment, more comorbidities), associated with factors such as Indigenous self-identification and rural residence. CONCLUSIONS: A syndemic approach enables us to identify health inequities in RMD, as shown by higher prevalence of comorbidities, disability and socioeconomic factors like lower educational attainment. These inequities exist for the overall population of patients with RMD, although it is more evident in Indigenous groups with added layers of vulnerability.

RESUMO

Rheumatoid arthritis (RA) affects approximately 1.5% of the population worldwide and 0.5-3.3% of the Mexican population. The presence of rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA) and anti-carbamylated protein (anti-CarP) antibodies has been described in populations at risk of RA development, such as first-degree relatives (FDR). Anti-CarP antibodies are present in RA patients (44%), FDR of RA patients (18%) and healthy controls (4.7%). Anti-CarP antibodies have not been described in FDR of the Mexican population. The objective of this study was to determine the prevalence of Rheumatoid Factors (RF) isotypes, ACPA and anti-CarP antibodies isotypes in FDR of RA patients. An observational, cross-sectional study, in an FDR of RA cohort, was performed. We measured IgA, IgG and IgM isotypes of RF, ACPA and anti-CarP antibodies. A total of 144 FDRs from 99 RA patients were enrolled. The prevalence of anti-CarP antibodies was 2.8% for IgA, 4.2% for IgG, whereas IgM was not detected. The serologic association was for RF/ACPA 4.48%, RF/anti-CarP 2.7%, FR 64.5%, ACPA 1.3%, ACPA/anti-CarP 0.69%, anti-CarP 3.4%, and no RF/ACPA/anti-CarP was observed. We found a low prevalence of anti-CarP antibodies in our cohort of FDR of RA patients, but the prevalence of ACPA and RF were higher than other cohorts previously reported.

RESUMO

INTRODUCTION/OBJECTIVES: First-degree relatives (FDR) of patients with rheumatoid arthritis (RA) are at increased risk of RA diagnosis. Magnetic resonance imaging (MRI) has been proposed as a useful tool to detect subclinical synovitis and bone abnormalities as predictors of progression to RA. The presence of grade ≥ 2 bone erosions in RA MRI scoring system (RAMRIS) was reported to be RA-specific. We aim to describe the prevalence and characteristics of MRI findings in RA patients and FDR. METHODS: A cross-sectional and exploratory study of 60 individuals was performed in 38 RA patients and 22 FDR with hand arthralgia without clinical arthritis and positive rheumatoid factor or anticitrullinated protein antibodies. All patients underwent an MRI and were evaluated for synovitis, bone erosion, and bone marrow edema. We evaluated second to fifth metacarpophalangeal joints of the dominant hand according to RAMRIS. RESULTS: Among the total population, eighteen (30%) subjects had grade ≥ 2 bone erosions, and 42 (70%) had at least one erosion of any grade. In patients with grade ≥ 2 bone erosions, 12 (31.6%) were from RA patients and 6 (27.2%) from FDR (p = 0.72). In patients with erosions of any grade, 26 (68.4%) were from RA patients and 15 (68.2%) were from FDR (p = 0.98). CONCLUSION: A high prevalence of bone erosions was found in RA patients' FDR who had symptoms without clinical arthritis and positive serology. MRI might be helpful in this population for an early detection of RA-specific erosions. The prognosis and the treatment decisions in these subjects should be elucidated. KEY POINTS: • First-degree relatives (FDR) of rheumatoid arthritis (RA) patients with positive serology and joint symptoms constitute a select subpopulation of individuals with an increased risk of developing RA. • Magnetic resonance imaging (MRI) of FDR shows a high prevalence of bone erosions of any grade, grade ≥ 2 erosions, and synovitis. • MRI might be helpful in FDR of RA patients to screen for the presence of RA-specific erosions or clinically undetectable synovitis.

RESUMO

INTRODUCTION: FM is a chronic musculoskeletal disorder characterized by the presence of generalized pain. There are contradictory results regarding the prevalence and supplementation effect of vitamin D deficiency on FM patients. We aim to determine the safety and efficacy of a 12-week vitamin D supplementation on FM patients. METHODS: We conducted a randomized, placebo-controlled, double-blind clinical trial. We included female participants of 18 years old or older, who met 1990 or 2010 ACR criteria for fibromyalgia. The Spanish validated FIQ and the VAS of pain were applied at baseline. The participants were then randomized to receive placebo or 50,000 IU of Vitamin D3 PO, weekly for 12 weeks. RESULTS: We included 80 patients. There was no statistical difference in the initial and final FIQ between both groups. The FIQ delta also did not prove to be different at the end of the study. The increase in vitamin D levels in the intervention group was corroborated. Regarding serious adverse effects, none was reported in both groups. There was no statistical difference in minor adverse events. CONCLUSION: In this double-blind placebo-controlled randomized study conducted to measure the efficacy and safety of vitamin D exclusively in patients with FM, we found that there is no evidence of a trend in favor of vitamin D treatment, since we did not observe improvement in the VAS of pain or FIQ. TRIAL REGISTRY: Clinical Trials.gov number: NCT03369379 Key Points • There are conflicting results in vitamin D to treat fibromyalgia. • In this double-blind, randomized controlled trial, we did not find a difference in the VAS nor FIQ with vitamin D supplementation. • The increase in vitamin D levels in the intervention group was corroborated.

RESUMO

Objective: Subfertility is commonly observed in patients with rheumatoid arthritis (RA). Although the causes are not well established, the alteration of the ovarian reserve is thought to contribute to the lower chances of pregnancy. This cross-sectional study aimed to evaluate the ovarian reserve in patients with RA. Materials and methods: Two parameters associated with ovarian reserves such as the antral follicle count (AFC) and the anti-müllerian hormone (AMH) were assessed in 38 patients with RA. We also analyzed the correlation of these parameters with the medication used to treat this pathology and with the illness severity. Results: The AMH levels in women with RA were comparable to those found on healthy individuals although the RA patients were more likely to have a low AFC. Ovarian reserve and RA were neither influenced by parameters of disease activity nor by the use of medication. Conclusion: The ovarian reserve in women with RA was similar to that found in healthy individuals.

RESUMO

BACKGROUND/OBJECTIVES: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by swelling, tenderness and destruction of synovial joints, leading to severe disability and premature mortality. The aim of the study was to determine the diagnostic accuracy of the 3 isotypes of rheumatoid factor (RF), anti-citrullinated peptide antibodies (ACPA) and the combination of both, for the diagnosis of rheumatoid arthritis (RA) in non-selected patients with inflammatory arthralgia. METHODS: We include 129 patients with inflammatory Arthalgia from a third level reference Center of rheumatic diseases in Monterrey, México. Their samples were analyzed for RF isotypes (IgA, IgG, and IgM) by ELISA (EUROINMUN), using a cut-off of 20IU/ml, and for ACPA's 5IU/ml; a medical examination was performed to obtain the definitive diagnoses of the patients. Data analysis was carried out using ROC curves for the measurement of sensitivity, specificity, for diagnostic accuracy to verify if the use of 3 RF isotypes and ACPA had a better prediction for the diagnosis of RA than use only one isotype and the ACPA alone. RESULTS: The ROC showed a sensitivity and specificity of the different antibodies with different cut-off points, being the best for the IgM with 0.802 followed by ACPA, IgA and IgG with 0.771, 0.63, and 0.728 respectively without statistical difference, the sensitivity and specificity of the combination of the 4 antibodies were 81.4 and 73.66%. CONCLUSION: In non-selected patients with inflammatory arthralgia, the combination of ACPA and isotypes of RF did not demonstrate more sensibility and specificity than IgM isoform of rheumatoid factor measurement only. We recommend that in the clinical scenario of arthralgia, where the diagnoses are Lupus, Sjogren syndrome and Osteoarthritis, RF IgM isoform is used followed by ACPA.

RESUMO

Systemic lupus erythematosus (SLE) is an autoimmune disease, characterized by multi-organ symptomatology. 16% of the patients with autoimmune thrombocytopenia have SLE and are associated with high mortality. Intravenous methylprednisolone or high-dose steroids are the first-line treatments in those patients who experienced life-threatening bleeding or have a severely low platelet count, whereas a second line includes splenectomy, as well as other immunosuppressive agents as monotherapy or combined therapy, including azathioprine, cyclophosphamide, cyclosporine, and mycophenolate mofetil. However, response rates of these therapies vary considerably. Rituximab (RTX) became a useful tool in the treatment of autoimmune diseases, due to the decrease of autoantibodies production. In addition, there is evidence that low doses of RTX (100 mg IV per week for 4 weeks) can have a similar effect compared to the standard dose. The objective of this study was to describe the response to low doses of RTX in patients with lupus-induced thrombocytopenia. We present a report of four female patients with newly diagnosed SLE, accompanied by purpuric syndrome and severe thrombocytopenia (< 30 × 109/L) as the clinical debut that was refractory to glucocorticoids (GC) therapy and treated with low doses of RTX. By week 5, complete response (> 100 × 109/L) was achieved in two patients, partial response (> 50 × 109/L) in 1 patient, and no response in one patient. There is little information on the treatment of SLE-associated autoimmune thrombocytopenia. The most extensive study found at the time of our search was the study of 10 Asian patients. They found that 80% of the patients responded by week four and maintained until week 24 of follow-up. At week 36, a follow-up for two patients showed relapse; this occurred on patients with the most disease duration (> 5 years) and was associated with a lower response rate. In contrast, our study with four patients found that half of them presented a complete response: one patient added concomitant therapy with azathioprine (AZA) and another patient without the concomitant therapy. A third patient with a partial improvement, this was seen by week five of treatment. Moreover, a fourth patient who did not have a response by week five of treatment presented a clinical response in subsequent appointments with a count of > 100 at week 24. Those patients who required concomitant use of AZA were patients who had positive antiphospholipid serology. The use of low-dose RTX for the management of severe thrombocytopenia refractory to GC in patients with SLE has a good response. It could be a safe, economical, and effective therapy.

RESUMO

First-degree relatives (FDR) of patients with rheumatoid arthritis (RA) have a higher risk for the development of RA. In the stages prior to the development of arthritis, nonspecific musculoskeletal (MSK) manifestations may occur. The aim of the study is to describe the frequency of rheumatic regional pain syndromes (RRPS) in FDR of RA patients. A cross-sectional study was carried out from July 2016 to September 2018. Parents, offspring, and siblings of RA patients completed the Community Oriented Program in the Rheumatic Diseases (COPCORD) questionnaire. Rheumatoid factor (RF) IgG, IgM, and IgA; anticitrullinated peptide antibodies (ACPAs); C-reactive protein (CRP); and erythrocyte sedimentation rate (ESR) were determined. All subjects with a positive COPCORD (defined by the presence of musculoskeletal pain) were evaluated and classified. Three hundred thirty-five FDRs participated, 75.8% were female, mean age of 44.15 years; 138 (41.2%) were diagnosed with at least one RRPS; 72 (21.5%) had rotator cuff tendinitis, 51 (15.2%) pes anserine bursitis, and 39 (11.6) lateral epicondylitis; RA was diagnosed in 24 (7.16%) subjects, undifferentiated arthritis (UA) in 30 (8.9%) and inflammatory arthralgia (AI) in 104 (31%). We found anti-CCP positivity in 6.8%, RF IgA in 22.3%, RF IgM in 48.6%, and RF IgG in 8.9%. The presence of RRPS was higher in this RA-FDR group compared to general population. Clinical evaluation of this risk group should include screening for RRPS.

RESUMO

BACKGROUND/PURPOSE: Helicobacter pylori (H. pylori) infection is the most common in the world and is associated with various gastrointestinal pathologies, including chronic gastritis, peptic ulcers, and gastric cancer. The prevalence is associated with socioeconomic conditions, with this infection being more common in developing countries than in developed countries. The presence and permanence of H. pylori in the oral cavity has been reported, but its role is controversial. The aim of this study was to determine the prevalence of H. pylori in dental plaque of patients with periodontitis. MATERIALS AND METHODS: A cross-sectional study was carried out and Periodontal Screening and Recording (PSR) index was determined. 38 dental plaque samples were taken and total DNA was extracted and qPCR was performed. RESULTS: 60.5% of the samples (n = 23) were positive for the presence of H. pylori by the amplification of the 16S rRNA and vacA genes. In addition, cagA gene was detected in 21.7% (n = 5) of H. pylori-positive. A significant relationship between periodontal status and H. pylori oral infection was found (P ≤ 0.05); patients with initial and moderate periodontitis were the most affected with 39.1% and 30.4%, respectively. CONCLUSION: Our results suggest that the prevalence of H. pylori in the oral cavity could be related to the progression of periodontal disease. Therefore, oral hygiene and treatment for the elimination of oral H. pylori could stop the progression of periodontal disease.

RESUMO

Genome editing reemerged in 2012 with the development of CRISPR/Cas9 technology, which is a genetic manipulation tool derived from the defense system of certain bacteria against viruses and plasmids. This method is easy to apply and has been used in a wide variety of experimental models, including cell lines, laboratory animals, plants, and even in human clinical trials. The CRISPR/Cas9 system consists of directing the Cas9 nuclease to create a site­directed double­strand DNA break using a small RNA molecule as a guide. A process that allows a permanent modification of the genomic target sequence can repair the damage caused to DNA. In the present study, the basic principles of the CRISPR/Cas9 system are reviewed, as well as the strategies and modifications of the enzyme Cas9 to eliminate the off­target cuts, and the different applications of CRISPR/Cas9 as a system for visualization and gene expression activation or suppression. In addition, the review emphasizes on the potential application of this system in the treatment of different diseases, such as pulmonary, gastrointestinal, hematologic, immune system, viral, autoimmune and inflammatory diseases, and cancer.

RESUMO

OBJECTIVE: The aim of this study was to measure the impact of osteoarthritis on the functioning and health status of individuals living in a low-income urban community in Mexico. METHODS: We conducted a cross-sectional, community-based study from December 2014 to November 2015, using the Community Oriented Program for Control of Rheumatic Diseases methodology to identify cases of musculoskeletal disease in a sample of adults older than 18 years in Pueblo Nuevo, Apodaca, Mexico. Two rheumatologists confirmed all cases of osteoarthritis (OA) using predefined criteria. Functioning was evaluated through (a) self-report of difficulty doing personal care, work, and leisure activities; (b) the modified Stanford Health Assessment Questionnaire-Disability Index; and (c) the Timed Up and Go test. Health status was evaluated using the EuroQoL 5 Dimensions. Statistical analyses were performed using χ tests and logistic regression models. RESULTS: Four hundred thirty-nine individuals with a mean age of 45.2 years were included, and 83 cases of OA were confirmed. The presence of OA was not significantly associated with having difficulties to do personal care, work, or leisure activities, but it was significantly associated with a higher Health Assessment Questionnaire-Disability Index score, longer time to complete the Timed Up and Go, and lower health status. CONCLUSIONS: Osteoarthritis is associated with having higher disability and worse health status in the community studied. A disability paradox was detected as some individuals perceived disability for doing standard activities but did not present disability performing their real-life activities. This underlies the importance of addressing the mental dimension during the management of this population.

RESUMO

Studies have proposed that Porphyromonas gingivalis (Pg) and Tannerella forsythia (Tf) promote a nonspecific inflammatory response that could produce systemic disease. Oral inoculation of Pg and Tf on the immune and arthritis response was evaluated in BALB/C mice divided into four groups: (1) sham; (2) food contaminated with Pg/Tf; (3) complete Freund's adjuvant (CFA) + Pg/Tf; and (4) CFA alone. CFA was administered subcutaneously on days 1 and 14. The arthritis response was monitored for 21 days after day 14 of CFA administration. IL-1ß and IL-6 were determined in serum. T cell activation was evaluated by CD25 in salivary lymph nodes or mouse spleen. Pad inflammation appeared by day 19 in the CFA group, but animals with bacteria inoculation presented a delay. A significant increase in IL-6 was found in Groups 3 and 4, but not with respect to IL-1ß. We observed an increase in CD25 in cells derived from cervical nodes and in animals with bacteria inoculation and CFA. A local immune response was observed in mice inoculated with Pg and Tf (T cell activation); a systemic response was observed with CFA. Since pad inflammation was delayed by bacterial inoculation this suggests that local T cell activation could decrease pad inflammation.

RESUMO

INTRODUCTION: In Mexico, other risk factors are associated with hepatitis C virus (HCV): prior heroin users, living alone, widower, and northern region residence. Rheumatoid arthritis (RA) patients are considered immunosuppressed and HCV testing is recommended before treatment. The aim of the study was to describe the characteristics of HCV testing in RA patients in three different medical care settings in a non-endemic area. METHODS: A retrospective observational study was performed using medical records from 960 RA patients describing the indications for HCV testing. RESULTS: The test was performed in 28.6% and the HCV overall frequency was 0.36%. Population characteristics were not associated with an increased risk of HCV infection; therefore, anti-HCV positivity was low. The main reason for testing was before starting biological agents. CONCLUSION: Due to the low pre-test probability, testing for HCV infection should be personalized; i.e., according to disease prevalence in a particular geographical location and the individual risk factors.

RESUMO

Multilevel studies have gained importance for highlighting social inequalities in health. These associations have been reported previously in diseases such as arthritis and chronic pain. We conducted a cross-sectional study using multilevel analysis to identify individual and contextual factors associated with the variation of prevalence of osteoarthritis (OA) in the Mexican population. The sample included 17,566 individuals of which 10,666 (60.7%) were women. The relationship between individual and contextual factors and OA were analyzed with a multilevel strategy. From the total population, 1,681 individuals had OA. Multilevel analysis showed that individual variables such as female gender (odds ratio (OR) = 1.3, 95% confidence interval (CI) 1.1, 1.4), age range 55-65 years (OR = 1.6, 95% CI 1.3, 2.0), musculoskeletal pain in the last 7 days (OR = 2.6, 95% CI 2.3, 3.0), and use of pain treatments (OR = 1.4, 95% CI 1.2, 1.7) were associated with OA. At the regional level, the Social Gap Index (SGIx) was associated with the diagnosis of OA (coefficient 0.5, 95% CI 0.2-1.1). The SGIx contextual variable was positively associated with the regional prevalence of OA and the variation in prevalence of OA in different regions. The larger the social gap, the greater the variation in OA prevalence. These factors were independently associated with the prevalence of OA: female gender, pain intensity, physical limitation, and the use of pain treatments were individual variables associated with OA. The association between OA prevalence and regional variations with SGIx reflects inequities in health provisions that should be considered in health programs.

RESUMO

The Gaenslen´s compression maneuver is the application of pressure on the metacarpophalangeal joints in order to evoke pain on a patient who has active synovitis. The results from the use of the maneuver are seen as controversial due to the lack of information describing the technique required for this procedure. The present study will aim to clarify uncertainty in regard to the form, pressure, and time required to apply the maneuver by rheumatologist. Rheumatologist were observed and monitored while performing the Gaenslen compression maneuver on a prosthetic, biomedical device. The device was shaped to mimic a human hand and equipped with a sensor to monitor the force and time of which the pressure was applied. One hundred and eight (62 %) participants gave a valid recording. From these, 121 (87.7 %) were made by certified rheumatologists. The most predominant method (104 physicians/75.4 %) of applying the maneuver was by using the right hand with superior approach. The median strength calculated in grams resulted in 299 gr (IQR 145) (range 150-741 gr). The median time expressed in milliseconds was of 956.6 ms (IQR 824.6) . This is the first study to assess a clinical maneuver in a qualitative and quantitative manner. The results from this study, more specifically the low number of usable recordings, and the wide range of force exerted in the squeeze test may explain the differences in sensitivity and specificity in clinical studies.

RESUMO

BACKGROUND: The rheumatoid arthritis is a clinical entity capable to cause hearing impairment that can be diagnosed promptly with high frequencies audiometry. OBJECTIVE: To detect subclinical sensorineural hearing loss in patients with rheumatoid arthritis. MATERIAL AND METHODS: Cross-sectional study on patients with rheumatoid arthritis performing high frequency audiometry 125Hz to 16,000Hz and tympanometry. The results were correlated with markers of disease activity and response to therapy. RESULTS: High frequency audiometry was performed in 117 female patients aged from 19 to 65 years. Sensorineural hearing loss was observed at a sensitivity of pure tones from 125 to 8,000 Hz in 43.59%, a tone threshold of 10,000 to 16,000Hz in 94.02% patients in the right ear and in 95.73% in the left ear. Hearing was normal in 8 (6.84%) patients. Hearing loss was observed in 109 (93.16%), and was asymmetric in 36 (30.77%), symmetric in 73 (62.37%), bilateral in 107 (91.45%), unilateral in 2 (1.71%), and no conduction and/or mixed hearing loss was encountered. Eight (6.83%) patients presented vertigo, 24 (20.51%) tinnitus. Tympanogram type A presented in 88.90% in the right ear and 91.46% in the left ear, with 5.98 to 10.25% type As. Stapedius reflex was present in 75.3 to 85.2%. Speech discrimination in the left ear was significantly different (p = 0.02)in the group older than 50 years. No association was found regarding markers of disease activity, but there was an association with the onset of rheumatoid arthritis disease. CONCLUSIONS: Patients with rheumatoid arthritis had a high prevalence of sensorineural hearing loss for high and very high frequencies.
