“…One of the hypotheses informing this research was that belonging to the indigenous population is a risk factor on its own for having rheumatic disease. However, our analysis revealed that speaking an indigenous language is also a borderline risk factor [ 32 ]. Although these results are not conclusive, we deem it justifiable to continue studies so as to properly assess indigenous populations in this regard.…”

This study aimed to estimate the prevalence of musculoskeletal (MSK) disorders and rheumatic diseases in the Chontal and Mixtec indigenous communities in the state of Oaxaca, Mexico, using the Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) methodology. After cross-culturally validating the COPCORD questionnaire for these communities, we conducted a cross-sectional, analytical, community-based census study using a house-to-house method. Positive cases of MSK disorders were assessed by primary care physicians and rheumatologists. The study population included participants aged ≥18 years from the indigenous communities of San Antonio Huitepec and San Carlos Yautepec. A total of 1061 persons participated in the study. Mean age was 46.9 years (standard deviation 19.9; age range 18–97 years); 642 (60.5 %) were women; 483 participants (45.5; 42.4–48.5 %) had MSK pain in the previous 7 days. Diagnoses were back pain 170 (16.0 %; 95 % confidence interval [CI] 13.8–18.3); osteoarthritis 157 (14.7 %; 95 % CI 12.7–17.0); rheumatic regional pain syndrome 53 (4.9 %; 95 % CI 3.7–6.4); rheumatoid arthritis 4 (0.3 %; 95 % CI 0.1–0.9); dermatomyositis 1 (0.09 %; 95 % CI 0.0–0.5); ankylosing spondylitis 1 (0.09 %; 95 % CI 0.0–0.5); systemic lupus erythematosus 1 (0.09 %; 95 % CI 0.02–0.5); and gout 1 (0.09 %; 95 % CI 0.0–0.5). 53.2 % had not received medical treatment for their disease. The prevalence of MSK disorders in indigenous communities in the Mixtec and Chontal regions is very high. The most common rheumatic diseases found were back pain and osteoarthritis. A high percentage of participants had not received medical care.

“…In Latin American (LA), previous studies have shown that people belonging to an indigenous group are associated with the prevalence of rheumatic disease as the rheumatoid arthritis (RA) [28]. Due to the presence in LA of indigenous groups, all countries and their condition of vulnerability, not only socioeconomic but also ethnic, were created the Latin American Group for the Study of Rheumatic Diseases in Original Populations (Grupo Latino Americano De estudio de Enfermedades Reumáticas en Pueblos Originarios; GLADERPO).…”

Work-related musculoskeletal disorders (MSDs) are a constellation of painful disorders, which could cause chronic disability. Multiple risk factors, both occupational and non occupational, may be involved. MSDs have been extensively studied in several countries; however, few studies have been carried out based on the relationship between MSDs and ethnicity. Objective: To describe the relationship between MSDs and ethnicity in diferent parts of the world.Methods: A nonsystematic literature review of studies, with both quantitative and qualitative methodology, was conducted.Results: The evidence in research, qualitative and quantitative, emphasizes the importance of this problem in vulnerable populations in diferent parts of the world, prioritizing migration to developed countries and precarity condition of work.Conclusion: Recommendations for a multidisciplinary approach of MSDs in vulnerable groups were raised.

“…RA affects 1 % of the world’s population [1], and its prevalence among Mexicans is 1.6 % [2]. RA inflames the synovial membrane of diarthrodial joints and damages the articular tissues, leading to severe functional disarrangement of the entire joint.…”

Hypoxia and its implications in rheumatoid arthritis

2016

View full text Add to dashboard Cite

Alterations in tissue oxygen pressure contribute to a number of diseases, including rheumatoid arthritis (RA). Low partial pressure of oxygen, a condition known as hypoxia, is a relevant feature in RA since it is involved in angiogenesis, inflammation, apoptosis, cartilage degradation, energy metabolism, and oxidative damage. Therefore, alterations in hypoxia-related signaling pathways are considered potential mechanisms of disease pathogenesis. The objective of this review is to highlight and update our current knowledge of the role of hypoxia in the pathogenesis of RA. We describe the experimental evidence that RA synovial tissue exists in a hypoxic state, as well as the origin and involvement of synovial hypoxia in different aspects of the pathogenic process.
