A variation in RA prevalence is also expected across Africa and the Middle East, due to ethnic, climate, and socioeconomic differences. To assess the prevalence of RA in Africa and the Middle East, we searched Medline (via PubMed) and databases of major rheumatology conferences. Seventeen journal articles and 0 abstracts met the inclusion criteria. Estimated prevalence ranged from 0.06 to 3.4%. Most studies reported values near or below 0.25%. Consistent with data from other regions, RA was more prevalent among urban than rural populations, and among women than men. The women:men prevalence ratio ranged from 1.3:1 to 12.5:1, which suggests notable differences from the global average of 2:1. Relative increases in prevalence were observed in North Africa and the Middle East (13% since 1990) and Western Sub-Saharan Africa (14%), whereas rates in Eastern, Central, and Southern Sub-Saharan Africa show decreases (4&#8211;12%). Low disease awareness, delays to visit rheumatologists, and socioeconomic factors appear to hinder early diagnosis and aggressive treatment. Few countries have developed RA-specific treatment guidelines, and many physicians and patients face limited access to even basic treatments. An improved understanding of the epidemiology and management of RA, and the related socioeconomic consequences is necessary, so that targeted attempts can be made to encourage early diagnosis and treatment."/> <meta name="prism.issn" content="2198-6584"/> <meta name="prism.publicationName" content="Rheumatology and Therapy"/> <meta name="prism.publicationDate" content="2020-11-23"/> <meta name="prism.volume" content="8"/> <meta name="prism.number" content="1"/> <meta name="prism.section" content="ReviewPaper"/> <meta name="prism.startingPage" content="1"/> <meta name="prism.endingPage" content="16"/> <meta name="prism.copyright" content="2020 The Author(s)"/> <meta name="prism.rightsAgent" content="journalpermissions@springernature.com"/> <meta name="prism.url" content="https://link.springer.com/article/10.1007/s40744-020-00252-1"/> <meta name="prism.doi" content="doi:10.1007/s40744-020-00252-1"/> <meta name="citation_pdf_url" content="https://link.springer.com/content/pdf/10.1007/s40744-020-00252-1.pdf"/> <meta name="citation_fulltext_html_url" content="https://link.springer.com/article/10.1007/s40744-020-00252-1"/> <meta name="citation_journal_title" content="Rheumatology and Therapy"/> <meta name="citation_journal_abbrev" content="Rheumatol Ther"/> <meta name="citation_publisher" content="Springer Healthcare"/> <meta name="citation_issn" content="2198-6584"/> <meta name="citation_title" content="A Review of the Prevalence and Unmet Needs in the Management of Rheumatoid Arthritis in Africa and the Middle East"/> <meta name="citation_volume" content="8"/> <meta name="citation_issue" content="1"/> <meta name="citation_publication_date" content="2021/03"/> <meta name="citation_online_date" content="2020/11/23"/> <meta name="citation_firstpage" content="1"/> <meta name="citation_lastpage" content="16"/> <meta name="citation_article_type" content="Review"/> <meta name="citation_fulltext_world_readable" content=""/> <meta name="citation_language" content="en"/> <meta name="dc.identifier" content="doi:10.1007/s40744-020-00252-1"/> <meta name="DOI" content="10.1007/s40744-020-00252-1"/> <meta name="size" content="193087"/> <meta name="citation_doi" content="10.1007/s40744-020-00252-1"/> <meta name="citation_springer_api_url" content="http://api.springer.com/xmldata/jats?q=doi:10.1007/s40744-020-00252-1&amp;api_key="/> <meta name="description" content="Estimates of the global prevalence of rheumatoid arthritis (RA) range from 0.24 to 1%, but vary considerably around the globe.

A variation in RA prevalence is also expected across Africa and the Middle East, due to ethnic, climate, and socioeconomic differences. To assess the prevalence of RA in Africa and the Middle East, we searched Medline (via PubMed) and databases of major rheumatology conferences. Seventeen journal articles and 0 abstracts met the inclusion criteria. Estimated prevalence ranged from 0.06 to 3.4%. Most studies reported values near or below 0.25%. Consistent with data from other regions, RA was more prevalent among urban than rural populations, and among women than men. The women:men prevalence ratio ranged from 1.3:1 to 12.5:1, which suggests notable differences from the global average of 2:1. Relative increases in prevalence were observed in North Africa and the Middle East (13% since 1990) and Western Sub-Saharan Africa (14%), whereas rates in Eastern, Central, and Southern Sub-Saharan Africa show decreases (4&#8211;12%). Low disease awareness, delays to visit rheumatologists, and socioeconomic factors appear to hinder early diagnosis and aggressive treatment. Few countries have developed RA-specific treatment guidelines, and many physicians and patients face limited access to even basic treatments. An improved understanding of the epidemiology and management of RA, and the related socioeconomic consequences is necessary, so that targeted attempts can be made to encourage early diagnosis and treatment."/> <meta property="og:image" content="https://static-content.springer.com/image/art%3A10.1007%2Fs40744-020-00252-1/MediaObjects/40744_2020_252_Fig1_HTML.png"/> <meta name="format-detection"

A variation in RA prevalence is also expected across Africa and the Middle East, due to ethnic, climate, and socioeconomic differences. To assess the prevalence of RA in Africa and the Middle East, we searched Medline (via PubMed) and databases of major rheumatology conferences. Seventeen journal articles and 0 abstracts met the inclusion criteria. Estimated prevalence ranged from 0.06 to 3.4%. Most studies reported values near or below 0.25%. Consistent with data from other regions, RA was more prevalent among urban than rural populations, and among women than men. The women:men prevalence ratio ranged from 1.3:1 to 12.5:1, which suggests notable differences from the global average of 2:1. Relative increases in prevalence were observed in North Africa and the Middle East (13% since 1990) and Western Sub-Saharan Africa (14%), whereas rates in Eastern, Central, and Southern Sub-Saharan Africa show decreases (4–12%). Low disease awareness, delays to visit rheumatologists, and socioeconomic factors appear to hinder early diagnosis and aggressive treatment. Few countries have developed RA-specific treatment guidelines, and many physicians and patients face limited access to even basic treatments. An improved understanding of the epidemiology and management of RA, and the related socioeconomic consequences is necessary, so that targeted attempts can be made to encourage early diagnosis and treatment.","datePublished":"2020-11-23T00:00:00Z","dateModified":"2020-11-23T00:00:00Z","pageStart":"1","pageEnd":"16","license":"http://creativecommons.org/licenses/by-nc/4.0/","sameAs":"https://doi.org/10.1007/s40744-020-00252-1","keywords":["Africa","Arab","Management","Middle East","Prevalence","Rheumatoid arthritis","Rheumatology","Orthopedics","General Practice / Family Medicine","Internal Medicine","Quality of Life Research"],"image":["https://media.springernature.com/lw1200/springer-static/image/art%3A10.1007%2Fs40744-020-00252-1/MediaObjects/40744_2020_252_Fig1_HTML.png"],"isPartOf":{"name":"Rheumatology and Therapy","issn":["2198-6584","2198-6576"],"volumeNumber":"8","@type":["Periodical","PublicationVolume"]},"publisher":{"name":"Springer Healthcare","logo":{"url":"https://www.springernature.com/app-sn/public/images/logo-springernature.png","@type":"ImageObject"},"@type":"Organization"},"author":[{"name":"Hani Almoallim","url":"http://orcid.org/0000-0003-2582-8317","affiliation":[{"name":"Umm-Al-Qura University","address":{"name":"Faculty of Medicine, Umm-Al-Qura University, Makkah, Saudi Arabia","@type":"PostalAddress"},"@type":"Organization"}],"email":"hmmoallim@uqu.edu.sa","@type":"Person"},{"name":"Jamal Al Saleh","affiliation":[{"name":"Dubai Hospital","address":{"name":"Dubai Hospital, Dubai, United Arab Emirates","@type":"PostalAddress"},"@type":"Organization"}],"@type":"Person"},{"name":"Humeira Badsha","affiliation":[{"name":"Dr Humeira Badsha Medical Center","address":{"name":"Dr Humeira Badsha Medical Center, Dubai, United Arab Emirates","@type":"PostalAddress"},"@type":"Organization"}],"@type":"Person"},{"name":"Haytham Mohamed Ahmed","url":"https://orcid.org/0000-0002-2883-3317","affiliation":[{"name":"Pfizer Biopharmaceutical Group, Emerging Markets","address":{"name":"Pfizer Biopharmaceutical Group, Emerging Markets, Dubai, United Arab Emirates","@type":"PostalAddress"},"@type":"Organization"}],"@type":"Person"},{"name":"Sara Habjoka","affiliation":[{"name":"Pfizer Biopharmaceutical Group, Emerging Markets","address":{"name":"Pfizer Biopharmaceutical Group, Emerging Markets, Dubai, United Arab Emirates","@type":"PostalAddress"},"@type":"Organization"}],"@type":"Person"},{"name":"Jeanine A.

A variation in RA prevalence is also expected across Africa and the Middle East, due to ethnic, climate, and socioeconomic differences. To assess the prevalence of RA in Africa and the Middle East, we searched Medline (via PubMed) and databases of major rheumatology conferences. Seventeen journal articles and 0 abstracts met the inclusion criteria. Estimated prevalence ranged from 0.06 to 3.4%. Most studies reported values near or below 0.25%. Consistent with data from other regions, RA was more prevalent among urban than rural populations, and among women than men. The women:men prevalence ratio ranged from 1.3:1 to 12.5:1, which suggests notable differences from the global average of 2:1. Relative increases in prevalence were observed in North Africa and the Middle East (13% since 1990) and Western Sub-Saharan Africa (14%), whereas rates in Eastern, Central, and Southern Sub-Saharan Africa show decreases (4–12%). Low disease awareness, delays to visit rheumatologists, and socioeconomic factors appear to hinder early diagnosis and aggressive treatment. Few countries have developed RA-specific treatment guidelines, and many physicians and patients face limited access to even basic treatments. An improved understanding of the epidemiology and management of RA, and the related socioeconomic consequences is necessary, so that targeted attempts can be made to encourage early diagnosis and treatment.</p></div></div></section> <div data-test="cobranding-download"> </div> <section aria-labelledby="inline-recommendations" data-title="Inline Recommendations" class="c-article-recommendations" data-track-component="inline-recommendations"> <h3 class="c-article-recommendations-title" id="inline-recommendations">Similar content being viewed by others</h3> <div class="c-article-recommendations-list"> <div class="c-article-recommendations-list__item"> <article class="c-article-recommendations-card" itemscope itemtype="http://schema.org/ScholarlyArticle"> <div class="c-article-recommendations-card__img"><img src="https://media.springernature.com/w215h120/springer-static/image/art%3Aplaceholder%2Fimages/placeholder-figure-springernature.png" loading="lazy" alt=""></div> <div class="c-article-recommendations-card__main"> <h3 class="c-article-recommendations-card__heading" itemprop="name headline"> <a class="c-article-recommendations-card__link" itemprop="url" href="https://link.springer.com/10.1186/s13643-020-01342-5?fromPaywallRec=false" data-track="select_recommendations_1" data-track-context="inline recommendations" data-track-action="click recommendations inline - 1" data-track-label="10.1186/s13643-020-01342-5">Epidemiology of rheumatoid arthritis in sub-Saharan Africa: a systematic review and meta-analysis protocol </a> </h3> <div class="c-article-meta-recommendations" data-test="recommendation-info"> <span class="c-article-meta-recommendations__item-type">Article</span> <span class="c-article-meta-recommendations__access-type">Open access</span> <span class="c-article-meta-recommendations__date">17 April 2020</span> </div> </div> </article> </div> <div class="c-article-recommendations-list__item"> <article class="c-article-recommendations-card" itemscope itemtype="http://schema.org/ScholarlyArticle"> <div class="c-article-recommendations-card__img"><img src="https://media.springernature.com/w215h120/springer-static/image/art%3A10.1007%2Fs00296-020-04731-0/MediaObjects/296_2020_4731_Fig1_HTML.png" loading="lazy" alt=""></div> <div class="c-article-recommendations-card__main"> <h3 class="c-article-recommendations-card__heading" itemprop="name headline"> <a class="c-article-recommendations-card__link" itemprop="url" href="https://link.springer.com/10.1007/s00296-020-04731-0?fromPaywallRec=false" data-track="select_recommendations_2" data-track-context="inline recommendations" data-track-action="click recommendations inline - 2" data-track-label="10.1007/s00296-020-04731-0">The global prevalence of rheumatoid arthritis: a meta-analysis based on a systematic review </a> </h3> <div class="c-article-meta-recommendations" data-test="recommendation-info"> <span class="c-article-meta-recommendations__item-type">Article</span> <span class="c-article-meta-recommendations__date">11 November 2020</span> </div> </div> </article> </div> <div class="c-article-recommendations-list__item"> <article class="c-article-recommendations-card" itemscope itemtype="http://schema.org/ScholarlyArticle"> <div class="c-article-recommendations-card__img"><img src="https://media.springernature.com/w215h120/springer-static/image/art%3Aplaceholder%2Fimages/placeholder-figure-springernature.png" loading="lazy" alt=""></div> <div class="c-article-recommendations-card__main"> <h3 class="c-article-recommendations-card__heading" itemprop="name headline"> <a class="c-article-recommendations-card__link" itemprop="url" href="https://link.springer.com/10.1007/s10067-015-3012-0?fromPaywallRec=false" data-track="select_recommendations_3" data-track-context="inline recommendations" data-track-action="click recommendations inline - 3" data-track-label="10.1007/s10067-015-3012-0">Burden of illness of rheumatoid arthritis in Latin America: a regional perspective </a> </h3> <div class="c-article-meta-recommendations" data-test="recommendation-info"> <span class="c-article-meta-recommendations__item-type">Article</span> <span class="c-article-meta-recommendations__access-type">Open access</span> <span class="c-article-meta-recommendations__date">01 March 2015</span> </div> </div> </article> </div> </div> </section> <script> window.dataLayer = window.dataLayer || [];

This uncertainty may be reflected in secular trends, too. Certain areas of Africa and the Middle East are experiencing an apparent increase in prevalence of RA, but decreasing rates were noted in others, primarily in Sub-Saharan Africa (Table <a data-track="click" data-track-label="link" data-track-action="table anchor" href="/article/10.1007/s40744-020-00252-1#Tab1">1</a>). However, the limited number of robust epidemiological studies covering entire countries or even wider regions likely hinder development of accurate estimates.</p><p>The diversity of populations and settings across Africa and the Middle East adds a challenge in obtaining reliable prevalence estimates of RA, and the presence of certain risk factors that influence RA prevalence may vary considerably from one local population to another. However, consistent with global estimates of urban and rural prevalence, RA is reported to occur at lower rates among rural populations of Africa and the Middle East than in urban settings.</p><p>The findings of this review support the general understanding that RA is more likely to occur in women than men [<a data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" aria-label="Reference 5" title="Cross M, Smith E, Hoy D, et al.

However, the women:men ratios of diagnosis vary considerably across countries. In addition to biological reasons for why RA is more common among women than men, study design and conduct and inclusion criteria might also contribute to some findings of unusually high ratios of women to men with RA. For example, if house-to-house surveys were conducted in the middle of the working day, women might comprise the primary respondents in some countries. Alternatively, men in some regions might be less likely to report joint pain to a study surveyor due to sociocultural factors. Cultural factors, economic limitations, and work requirements may also affect the number of men who seek care at primary health centers, thus affecting their inclusion in studies.</p><p>Migration between different parts of the region are common and are a major contributor to its high heterogeneity. Similar to European and East Asian patients with RA, certain <i>HLA–DRB1</i> alleles are associated with an increased risk of developing RA in Middle Eastern patients; however, two loci (5p13 and 17p13) have been identified as additional risk factors in this population [<a data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" aria-label="Reference 31" title="Saxena R, Plenge RM, Bjonnes AC, et al.

However, incidence rates can be difficult to evaluate in the absence of centralized hospital or healthcare systems or patient registries. In fact, studies on incidence rates of RA in Africa and the Middle East are scarce. In some countries, such as Egypt, the healthcare system consists primarily of private practitioners rather than hospital-based systems. In such cases, individual providers may sense competition from their colleagues and be reluctant to register patients in registries. The lack of rheumatologists in many countries in this region [<a data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" aria-label="Reference 32" title="Al Maini M, Adelowo F, Al Saleh J, et al.

In addition, some patients may visit healthcare professionals other than rheumatologists (e.g., general practitioners, orthopedic specialists). In Cameroon, this shortage of rheumatologists led to the centralization of diagnostic and therapeutic resources, which permits collection of data from a wide spectrum of patients but also increases pressure on tertiary centers to prescribe or monitor drugs in cases when primary and secondary care centers are unable to do so [<a data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" aria-label="Reference 33" title="Singwe-Ngandeu M, Meli J, Ntsiba H, et al.

This variation is partly related to differences in study design, but also to differences among populations and risk factors between (and even within) individual countries. However, general trends are consistent with the global data, wherein women and urban populations are at higher risk of the disease than are men and rural populations. One common factor across Africa and the Middle East is that populations are generally underdiagnosed and undertreated. This is in part related to low disease awareness and a lack of appropriate MSK examination skills on the part of healthcare providers, who may also attribute a lower importance to early diagnosis and treatment relative to the importance of other chronic diseases with which they are more familiar. Furthermore, in many areas, patients may encounter long wait times to see rheumatologists, and healthcare policies may delay effective treatment. Access to treatment can be limited in many areas. Financial cost is also a consideration for patients of low socioeconomic status. Many may discontinue treatment if they are not educated on the importance of continual treatment, and if doctor visits or medication costs accumulate.</p><p>Solutions to these unmet needs include increased focus on MSK examination skills, validation of diagnosis criteria, increased physician and patient awareness of the progressive nature of RA, and of the optimal treatment approaches as well as country-specific treatment guidelines.
