The impact of COVID-19 on rheumatology practice across Africa.

OBJECTIVES: To identify the changes in rheumatology service delivery across the five regions of Africa from the impact of the COVID-19 pandemic. METHODS: The COVID-19 African Rheumatology Study Group created an online survey consisting of 40 questions relating to the current practices and experiences of rheumatologists across Africa. The CHERRIES checklist for reporting results of internet e-surveys was adhered to. RESULTS: A total of 554 completed responses were received from 20 countries, which include six in Northern Africa, six in West Africa, four in Southern Africa, three in East Africa and one in Central Africa. Consultant grade rheumatologists constituted 436 (78.7%) of respondents with a mean of 14.5 ± 10.3 years of experience. A total of 77 (13.9%) rheumatologists avoided starting a new biologic. Face-to-face clinics with the use of some personal protective equipment continued to be held in only 293 (52.9%) rheumatologists' practices. Teleconsultation modalities found usage as follows: telephone in 335 (60.5%), WhatsApp in 241 (43.5%), emails in 90 (16.3%) and video calls in 53 (9.6%). Physical examinations were mostly reduced in 295 (53.3%) or done with personal protective equipment in 128 (23.1%) practices. Only 316 (57.0%) reported that the national rheumatology society in their country had produced any recommendation around COVID-19 while only 73 (13.2%) confirmed the availability of a national rheumatology COVID-19 registry in their country. CONCLUSION: COVID-19 has shifted daily rheumatology practices across Africa to more virtual consultations and regional disparities are more apparent in the availability of local protocols and registries.

Coalition for Health and Gender Equity (CHANGE)-a protocol for a global cross-sectional survey of health and gender equity in rheumatology.

Objectives: The primary aim of the CHANGE survey is to determine the current state of gender equity within rheumatology, and secondarily, to review the physician perspective on bullying, harassment and equipoise of opportunities within rheumatology. Methods: The CHANGE e-survey is a cross-sectional self-reported questionnaire adapted from EULAR's gender equity in academic rheumatology task force. The survey was launched in January 2023; it is available in six languages and distributed widely via rheumatology organizations and social media. Eligible participants include rheumatologist physicians and rheumatology health-care professionals. Survey responses will undergo descriptive analysis and inter-group comparison aiming to explore gender-based discrimination using logistic regression, with subgroup analyses for country/continent variations. Conclusion: This e-survey represents a comprehensive global initiative led by an international consortium, aimed at exploring and investigating the gender-related disparities and obstacles encountered by rheumatologists and rheumatology health-care professionals across diverse communities and health-care environments. By pursuing this initiative, we aim to take the broader rheumatology community a step closer to understanding the underlying origins of inequities and their determinants. Such insights are pivotal in identifying viable interventions and strategies to foster gender equity within the field. Ultimately, our collective objective is to ensure equitable access to opportunities for every individual, irrespective of gender, thereby promoting inclusivity and fairness across the entire spectrum of professional practice and career development.

Prevalence of glucocorticoid-induced osteoporosis among rheumatology patients in Africa: a systematic review and meta-analysis.

The prevalence of glucocorticosteroid-induced osteoporosis (GIOP) is well established in higher income countries. There are limited studies showing a wide prevalence of GIOP in Africa. Prospective studies are needed on GIOP in African rheumatology patients to implement appropriate management algorithms. PURPOSE: The prevalence of glucocorticosteroid-induced osteoporosis (GIOP) is well established in developed countries, but little is known about GIOP in African adult patients with inflammatory rheumatic musculoskeletal diseases (RMDs). This study aimed to determine the prevalence of GIOP and osteoporotic fracture risk in African patients with inflammatory RMDs according to radiographic and bone mineral density (BMD) findings. METHODS: PubMed, Google Scholar, Scopus, and African Index Medicus were searched up to 31 December 2020. Heterogeneity was assessed using I2 statistic across the included studies. A random-effects model was applied to estimate the pooled effect size across studies. All statistical analyses were performed using STATA™ version 14 software. The study was registered with PROSPERO, number CRD42021256252. RESULTS: In this meta-analysis, a total of 7 studies with 780 participants, stratified by geographical region were included. The pooled prevalence of GIOP based on BMD data was 47.7% (95% CI 32.9-62.8) with 52.2% (95% CI 36.5-67.6) in North African countries and 15.4% (95% 1.9-45.4%) in South Africa with a high heterogeneity (I2 = 93.3%, p = 0.018). There was no data from the rest of African countries. We were unable to complete the meta-analysis of osteoporotic fractures due to the lack of available data. CONCLUSION: This study revealed that the prevalence of GIOP varies significantly in Africa. There is no information, however, for most of Africa, and further prospective studies are needed to develop context-specific GIOP preventive strategies in patients with RMDs.

'It's about time'. Dissemination and evaluation of a global health systems strengthening roadmap for musculoskeletal health - insights and future directions.

Actions towards the health-related Sustainable Development Goal 3.4 typically focus on non-communicable diseases (NCDs) associated with premature mortality, with less emphasis on NCDs associated with disability, such as musculoskeletal conditions-the leading contributor to the global burden of disability. Can systems strengthening priorities for an underprioritised NCD be codesigned, disseminated and evaluated? A 'roadmap' for strengthening global health systems for improved musculoskeletal health was launched in 2021. In this practice paper, we outline dissemination efforts for this Roadmap and insights on evaluating its reach, user experience and early adoption. A global network of 22 dissemination partners was established to drive dissemination efforts, focussing on Africa, Asia and Latin America, each supported with a suite of dissemination assets. Within a 6-month evaluation window, 52 Twitter posts were distributed, 2195 visitors from 109 countries accessed the online multilingual Roadmap and 138 downloads of the Roadmap per month were recorded. Among 254 end users who answered a user-experience survey, respondents 'agreed' or 'strongly agreed' the Roadmap was valuable (88.3%), credible (91.2%), useful (90.1%) and usable (85.4%). Most (77.8%) agreed or strongly agreed they would adopt the Roadmap in some way. Collection of real-world adoption case studies allowed unique insights into adoption practices in different contexts, settings and health system levels. Diversity in adoption examples suggests that the Roadmap has value and adoption potential at multiple touchpoints within health systems globally. With resourcing, harnessing an engaged global community and establishing a global network of partners, a systems strengthening tool can be cocreated, disseminated and formatively evaluated.

Context and priorities for health systems strengthening for pain and disability in low- and middle-income countries: a secondary qualitative study and content analysis of health policies.

Musculoskeletal (MSK) health impairments contribute substantially to the pain and disability burden in low- and middle-income countries (LMICs), yet health systems strengthening (HSS) responses are nascent in these settings. We aimed to explore the contemporary context, framed as challenges and opportunities, for improving population-level prevention and management of MSK health in LMICs using secondary qualitative data from a previous study exploring HSS priorities for MSK health globally and (2) to contextualize these findings through a primary analysis of health policies for integrated management of non-communicable diseases (NCDs) in select LMICs. Part 1: 12 transcripts of interviews with LMIC-based key informants (KIs) were inductively analysed. Part 2: systematic content analysis of health policies for integrated care of NCDs where KIs were resident (Argentina, Bangladesh, Brazil, Ethiopia, India, Kenya, Malaysia, Philippines and South Africa). A thematic framework of LMIC-relevant challenges and opportunities was empirically derived and organized around five meta-themes: (1) MSK health is a low priority; (2) social determinants adversely affect MSK health; (3) healthcare system issues de-prioritize MSK health; (4) economic constraints restrict system capacity to direct and mobilize resources to MSK health; and (5) build research capacity. Twelve policy documents were included, describing explicit foci on cardiovascular disease (100%), diabetes (100%), respiratory conditions (100%) and cancer (89%); none explicitly focused on MSK health. Policy strategies were coded into three categories: (1) general principles for people-centred NCD care, (2) service delivery and (3) system strengthening. Four policies described strategies to address MSK health in some way, mostly related to injury care. Priorities and opportunities for HSS for MSK health identified by KIs aligned with broader strategies targeting NCDs identified in the policies. MSK health is not currently prioritized in NCD health policies among selected LMICs. However, opportunities to address the MSK-attributed disability burden exist through integrating MSK-specific HSS initiatives with initiatives targeting NCDs generally and injury and trauma care.

Access to care for low trauma hip fractures in South Africa.

RATIONALE: Early surgery is recommended for hip fractures. MAIN RESULT: In this study only one-third of subjects with hip fractures were admitted within 24 h of the fracture, and surgery was delayed beyond 48 h in the majority. SIGNIFICANCE: These findings highlight the need to improve access to care for hip fracture subjects. PURPOSE: There is limited data on the timing of admission and surgery following a low trauma hip fracture (HF) in South Africa (SA). METHODS: A prospective, observational study was conducted at public and private hospitals in three provinces, Gauteng (GP), KwaZulu-Natal (KZN) and the Western Cape (WC), in SA to determine time from fracture to admission and from admission to surgery in patients presenting with low trauma HF. Associations with delayed admission and surgery were explored using logistic regression. RESULTS: The median age of the 1996 subjects was 73 years (IQR 63-81 years), the majority were women (1346, 67%) and 1347 (67%) were admitted to the public hospitals. In one-third of subjects (661, 33%), admission was delayed to beyond 24 h after the fracture. There was a significantly longer time to admission in public compared to private hospitals (21 h [IQR 10.0-48.5] versus 6 h [IQR 3.3-14.1], p < 0.001), in subjects < 65 years, the WC and when admission occurred on a weekday. Surgery was delayed beyond 48 h in the majority (1272, 69%) of subjects and was significantly longer in public compared to private hospitals (130 h [IQR 62.6-212.4] versus 45.4 h [IQR 24.0-75.5], p < 0.001), in KZN, and when admission occurred after hours. CONCLUSION: The burden of HFs is higher at public hospitals in SA, where there is a significant delay in admission after a fracture and surgery after admission. This highlights the need for a review of HF care pathways, resources and policies.

Spondyloarthritis in North Africa: an update.

Spondyloarthritis (SpA) has been less well studied than rheumatoid arthritis in North Africa, due to a belief that it is rare and benign in certain populations. The main genetic trait of SpA is its association with human leukocyte antigen (HLA)-B27. The distribution of this allele largely explains the prevalence and severity of SpA. The prevalence of HLA-B27 in the general population of North Africa is estimated at about 4%, and rises to about 60% among people affected with SpA. Coxitis is one of the main features of North African SpA, but the response to treatment is comparable to the literature from the West. The major challenge in North Africa remains accessibility to specialized care and means of early diagnosis. Prevalent infections in North Africa do not seem to be a major obstacle to optimal treatment strategies.

The management of gout in Africa: challenges and opportunities.

The rise in non-communicable diseases in Africa presents challenges for health systems that are burdened by infectious diseases. Gout is one of those diseases that has seen an increase in numbers worldwide, including Africa. Gout is commonly associated with comorbidities and mortality. It directly impacts the quality of life, increases health costs, decreases physical function, and significantly increases the time from work, much of which is potentially avoided if treatment is instituted early. Despite advances in understanding the pathophysiology and outcomes of gout, the quality of care delivered to patients in Africa is still suboptimal. Existing data on gout in Africa reveals a general low index of suspicion due to limited knowledge of the disease by healthcare workers resulting in late diagnosis, with severe polyarticular tophaceous gout being a common presenting feature. These late presentations are associated with avoidable disability and increase the direct and indirect costs of managing gout. The challenges are related to lack of government budgetary support for staff training, infrastructure for diagnosis, and availing medicines. The picture of gout in Africa largely mirrors the west concerning risk factors, comorbidities, and burden of disease, but with some unique presentations seen in HIV, sickle cell disease, and vertigo. We discuss the challenges of gout diagnosis and management in Africa and propose a roadmap to improve gout outcomes across Africa.

FRAX-based fracture probabilities in South Africa.

The hip fracture rates in South Africa were used to create ethnic-specific FRAX® models to facilitate fracture risk assessment. INTRODUCTION: The aim of this study was to develop FRAX models to compute the 10-year probability of hip fracture and major osteoporotic fracture and assess their potential clinical application. METHODS: Age- and sex-specific incidence of hip fracture and national mortality rates were incorporated into a FRAX model for the White, Black African, Coloured and Indian population of South Africa. Age-specific 10-year probabilities of a major osteoporotic fracture were calculated in women to determine fracture probabilities at a femoral neck T score of -2.5 SD, or those equivalent to a woman with a prior fragility fracture. Fracture probabilities were compared with those from selected countries. RESULTS: Probabilities were consistently higher in Indian than in Coloured men and women, in turn, higher than in Black South Africans. For White South Africans, probabilities were lower than in Indians at young ages up to the age of about 80 years. When a BMD T score of -2.5 SD was used as an intervention threshold, FRAX probabilities in women age 50 years were approximately 2-fold higher than in women of the same age but with an average BMD and no risk factors. The increment in risk associated with the BMD threshold decreased progressively with age such that, at the age of 80 years or more, a T score of -2.5 SD was no longer a risk factor. Probabilities equivalent to women with a previous fracture rose with age and identified women at increased risk at all ages. CONCLUSIONS: These FRAX models should enhance accuracy of determining fracture probability amongst the South African population and help guide decisions about treatment.

Consensus evidence-based clinical practice guidelines for the diagnosis and treat-to-target management of osteoporosis in Africa: an initiative by the African Society of Bone Health and Metabolic Bone Diseases.

The objective of this consensus statement is to inform the clinical practice communities, research centres and policymakers across Africa of the results of the recommendations for osteoporosis prevention, diagnosis and management. The developed guideline provides state-of-the-art information and presents the conclusions and recommendations of the consensus panel regarding these issues. PURPOSE: To reach an African expert consensus on a treat-to-target strategy, based on current evidence for best practice, for the management of osteoporosis and prevention of fractures. METHOD: A 3-round Delphi process was conducted with 17 osteoporosis experts from different African countries. All rounds were conducted online. In round 1, experts reviewed a list of 21 key clinical questions. In rounds 2 and 3, they rated the statements stratified under each domain for its fit (on a scale of 1-9). After each round, statements were retired, modified or added in view of the experts' suggestions and the percent agreement was calculated. Statements receiving rates of 7-9 by more than 75% of experts' votes were considered as achieving consensus. RESULTS: The developed guidelines adopted a fracture risk-centric approach. Results of round 1 revealed that of the 21 proposed domains, 10 were accepted whereas 11 were amended. In round 2, 32 statements were presented: 2 statements were retired for similarity, 9 statements reached consensus, whereas modifications were suggested for 21 statements. After the 3rd round of rating, the experts came to consensus on the 32 statements. Frequency of high-rate recommendation ranged from 83.33 to 100%. The response rate of the experts was 100%. An algorithm for the osteoporosis management osteoporosis was suggested. CONCLUSION: This study is an important step in setting up a standardised osteoporosis service across the continent. Building a single model that can be applied in standard practice across Africa will enable the clinicians to face the key challenges of managing osteoporosis; furthermore, it highlights the unmet needs for the policymakers responsible for providing bone health care together with and positive outcomes of patients' care.

African League Against Rheumatism (AFLAR) preliminary recommendations on the management of rheumatic diseases during the COVID-19 pandemic.

OBJECTIVES: To develop recommendations for the management of rheumatic and musculoskeletal diseases (RMDs) during the COVID-19 pandemic. METHOD: A task force comprising of 25 rheumatologists from the 5 regions of the continent was formed and operated through a hub-and-spoke model with a central working committee (CWC) and 4 subgroups. The subgroups championed separate scopes of the clinical questions and formulated preliminary statements of recommendations which were processed centrally in the CWC. The CWC and each subgroup met by several virtual meetings, and two rounds of voting were conducted on the drafted statements of recommendations. Votes were online-delivered and recommendations were pruned down according to predefined criteria. Each statement was rated between 1 and 9 with 1-3, 4-6 and 7-9 representing disagreement, uncertainty and agreement, respectively. The levels of agreement on the statements were stratified as low, moderate or high according to the spread of votes. A statement was retired if it had a mean vote below 7 or a 'low' level of agreement. RESULTS: A total of 126 initial statements of recommendations were drafted, and these were reduced to 22 after the two rounds of voting. CONCLUSIONS: The preliminary statements of recommendations will serve to guide the clinical practice of rheumatology across Africa amidst the changing practices and uncertainties in the current era of COVID-19. It is recognized that further updates to the recommendations will be needed as more evidence emerges. Key Points • AFLAR has developed preliminary recommendations for the management of RMDs in the face of the COVID-19 pandemic. • COVID-19 is an unprecedented experience which has brought new concerns regarding the use of some disease-modifying anti-rheumatic drugs (DMARDs), and these recommendations seek to provide guidelines to the African rheumatologists. • Hydroxychloroquine shortage has become rampart across Africa as the drug is being used as prophylaxis against COVID-19 and this may necessitate a review of treatment plan for some patients with RMDs. • Breastfeeding should continue for as long as possible if a woman is positive for SARS-CoV-2 as there is currently no evidence that the infection can be transmitted through breast milk.

Health systems strengthening to arrest the global disability burden: empirical development of prioritised components for a global strategy for improving musculoskeletal health.

INTRODUCTION: Despite the profound burden of disease, a strategic global response to optimise musculoskeletal (MSK) health and guide national-level health systems strengthening priorities remains absent. Auspiced by the Global Alliance for Musculoskeletal Health (G-MUSC), we aimed to empirically derive requisite priorities and components of a strategic response to guide global and national-level action on MSK health. METHODS: Design: mixed-methods, three-phase design.Phase 1: qualitative study with international key informants (KIs), including patient representatives and people with lived experience. KIs characterised the contemporary landscape for MSK health and priorities for a global strategic response.Phase 2: scoping review of national health policies to identify contemporary MSK policy trends and foci.Phase 3: informed by phases 1-2, was a global eDelphi where multisectoral panellists rated and iterated a framework of priorities and detailed components/actions. RESULTS: Phase 1: 31 KIs representing 25 organisations were sampled from 20 countries (40% low and middle income (LMIC)). Inductively derived themes were used to construct a logic model to underpin latter phases, consisting of five guiding principles, eight strategic priority areas and seven accelerators for action.Phase 2: of the 165 documents identified, 41 (24.8%) from 22 countries (88% high-income countries) and 2 regions met the inclusion criteria. Eight overarching policy themes, supported by 47 subthemes, were derived, aligning closely with the logic model.Phase 3: 674 panellists from 72 countries (46% LMICs) participated in round 1 and 439 (65%) in round 2 of the eDelphi. Fifty-nine components were retained with 10 (17%) identified as essential for health systems. 97.6% and 94.8% agreed or strongly agreed the framework was valuable and credible, respectively, for health systems strengthening. CONCLUSION: An empirically derived framework, co-designed and strongly supported by multisectoral stakeholders, can now be used as a blueprint for global and country-level responses to improve MSK health and prioritise system strengthening initiatives.

Immune Mediated Necrotizing Myopathy: Where do we Stand?

Immune-mediated necrotizing myopathies (IMNMs) are a group of acquired autoimmune muscle disorders which are characterized by proximal muscle weakness, high levels of creatinine kinase, and myopathic findings on electromyogram (EMG). Muscle biopsy in IMNM differentiates it from the other subgroups of Idiopathic Inflammatory Myositis (IIM) by the presence of myofibre necrosis and prominent regeneration without substantial lymphocytic inflammatory infiltrates. Anti-signal recognition particle (SRP) and anti-3hydroxy-3 methylglutarylcoenzyme A reductase (HMGCR) autoantibodies were found in two-thirds of IMNM patients. In terms of treatment, IMNM is more resistant to conventional immunosuppressive treatment, therefore, other modalities of treatment such as Intravenous Immunoglobulin (IVIG) and rituximab are often required.

Osteoporosis in developing countries.

Osteoporosis poses a huge challenge in developing countries due to demographic transition and aging of the population coupled with limited availability of resources. The exact disease burden is difficult to quantify because of the paucity of data. Ethnicity affects bone density as well as fracture risk. Population-specific normative data for bone density are lacking in large parts of the world. Vitamin D deficiency is common even in sunny countries. The WHO has developed an algorithm for estimation of 10-year fracture risk which may be used even in the absence of bone mineral density.

Bone status after cessation of use of injectable progestin contraceptives.

BACKGROUND: Women using injectable progestin contraceptives (IPCs) have lower bone mineral density than nonusers. We assessed whether bone loss is completely reversible after cessation of IPC use, whether different IPCs have different effects and whether effects vary by age at first use. STUDY DESIGN: In a cross-sectional study in Cape Town, South Africa, 3487 premenopausal black and mixed race women aged 18-44 years were interviewed for information on contraceptive history and risk factors for decreased bone mineral density, and ultrasound measurements of the left calcaneus were taken. Adjusted means of the ultrasound measures for categories of IPC use were obtained using multivariable linear regression. RESULTS: Current users of IPCs had the lowest ultrasound measures, while the measures of women who had ceased IPC use at least 2-3 years previously were similar to or greater than those of never users of IPCs. The effects of depot medroxyprogesterone acetate and norethisterone enanthate were similar. The calcaneus measures were unrelated to age at which use began after control for confounding factors. CONCLUSION: The data suggest that bone loss during IPC use is reversible and that this loss of bone is completely recovered several years after cessation of use.

The spectrum of psoriatic arthritis in a South African cohort.

The aim of this study was to describe the clinical features of patients with psoriatic arthritis (PsA) in a South African cohort. This is a retrospective analysis of patients contributing to development of the international classification criteria for PsA, ClASsification criteria for Psoriatic ARthritis (CASPAR). Patients were all seen at the arthritis clinics at Groote Schuur Hospital, Cape Town. Demographic, clinical, laboratory and radiographic information was collected. This study describes the relevant findings relating to the clinical profile of the patients seen at our centre as well as the effect of family history and/or dactylitis in determining the severity of psoriatic arthritis. There were 45 patients with a male to female ratio of 1:1.25. The mean age of psoriasis onset was 38.34 years (SD 15.54), whilst that of arthritis onset was 43.86 years (SD 13.4). Polyarthritis was the commonest pattern and sacro-iliitis was uncommon. Dactylitis was present in 26%. The presence of family history or of dactylitis did not predict more severe disease. There was a significant correlation between tender and swollen joints. The mean Health Assessment Questionnaire (HAQ) score was 1.05. Eighty-three percent showed evidence of radiological changes, and distal interphalangeal (DIP) erosions were found in 54%. Arthritis mutilans was present in 31%. There were no black subjects in the cohort. The clinical patterns of PsA in our cohort are similar to those reported elsewhere. The paucity of blacks amongst this cohort requires further study. PsA-specific measures of disease activity need to be developed. PsA causes significant joint damage and disability.

DNA Oncogenic Virus-Induced Oxidative Stress, Genomic Damage, and Aberrant Epigenetic Alterations.

Approximately 20% of human cancers is attributable to DNA oncogenic viruses such as human papillomavirus (HPV), hepatitis B virus (HBV), and Epstein-Barr virus (EBV). Unrepaired DNA damage is the most common and overlapping feature of these DNA oncogenic viruses and a source of genomic instability and tumour development. Sustained DNA damage results from unceasing production of reactive oxygen species and activation of inflammasome cascades that trigger genomic changes and increased propensity of epigenetic alterations. Accumulation of epigenetic alterations may interfere with genome-wide cellular signalling machineries and promote malignant transformation leading to cancer development. Untangling and understanding the underlying mechanisms that promote these detrimental effects remain the major objectives for ongoing research and hope for effective virus-induced cancer therapy. Here, we review current literature with an emphasis on how DNA damage influences HPV, HVB, and EBV replication and epigenetic alterations that are associated with carcinogenesis.
