Pattern of systemic lupus erythematosus in NIGERIA: a multicentre descriptive hospital-based study.

INTRODUCTION: Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease with manifestations ranging from mild to life-threatening organ dysfunction. There is wide variability in the reported incidence and prevalence rate globally, particularly in low and middle-income countries. Nigeria had very few isolated reports of SLE from private and public hospitals Therefore, we conducted this large multi-center descriptive study to determine the sociodemographic, clinical profile, laboratory patterns, and treatment among Nigerian lupus patients. METHODS: A retrospective hospital-based study of all SLE patients seen over 4 years (January 2017 to December 2020) was conducted at 20 rheumatology clinics spread across the 6 geopolitical zones of Nigeria. All patients 18 years and above satisfying the American College of Rheumatology (ACR) 1997 and/or the Systemic Lupus International Collaboration Clinics (SLICC) 2012 classification criteria for SLE were enrolled. Patients with other Rheumatic and Musculoskeletal Diseases (RMDs) not in keeping with SLE and Patients with incomplete data were excluded. Data was analysed using SPSS version 23.0 software. RESULTS: A total of 896 patients with SLE were included in the final analysis with a mean age ± SD of 34.47 ± 11 and a female to male ratio of 8.1:1. Synovitis was reported by 61.6% of patients, while 51%, 19.9% and11.4% patients reported acute, sub-acute and chronic lupus rashes respectively. ANA was positive in 98.0% with titers ranging from 1:80 to 1:64,000. CONCLUSION: SLE is not rare in Nigeria. Most patients were female in their 3rd to 4th decades of life. There is a delayed presentation to a rheumatology facility. Arthritis and mucocutaneous manifestations were the most frequent presentation. Key Points •This study presents the first national data on SLE in Nigeria •This study showed that SLE is not rare in Nigeria in contrast to previous reports •There appear to be ethnic disparity in the frequency of lupus among Nigerians •Nigerians with lupus have very high titer of ANA.

Frequency, pattern, and associations of generalized osteoarthritis among Nigerians with knee osteoarthritis.

BACKGROUND: Osteoarthritis (OA) is a common degenerative condition leading to significant pain, functional limitation, and economic loss. Generalized OA (GOA) is associated with greater morbidity and accounts for 5-25% of total OA cases depending on definition used. This paper aims to determine the frequency and pattern of GOA, compare clinical and laboratory parameters of GOA and non-GOA subjects, then identify independent associations of GOA among Nigerians with knee OA. METHODS: A cross-sectional study of 180 knee OA patients with knee and generalized OA defined using ACR criteria. Questionnaire administration was followed by physical examination and appropriate radiographs. Data was summarized using tables and figures. Multivariate regression was done to identify independent GOA associations with statistical significance p<0.05. Ethical approval was obtained for the study. RESULTS: There were 180 participants with mean age 59.7±9.1 years. Twenty-eight patients (15.6%) had GOA of which 26 were female. The hip/knee/spine pattern was the commonest while hand OA was rare. Comparisons showed that GOA patients were significantly older with longer pain duration, higher pain score, more Heberden's nodes, and greater fatigue. There were no significant differences between both groups in levels of inflammatory markers and other laboratory parameters. Further analysis identified joint stiffness as the only independent association of GOA (OR 3.34, p=0.01). CONCLUSION: A 15.6% frequency of GOA was identified among knee OA sufferers with the hip/knee/spine pattern most frequent. Nigerians with GOA are predominantly females with a large joint phenotype. Joint stiffness was the only independent association of GOA observed. Key Points • Generalized osteoarthritis occurs in 15.6% of Nigerian patients with knee osteoarthritis. • Females are predominantly affected with a large joint phenotype involving the hip/knee/spine. • Joint stiffness is an independent association of generalized osteoarthritis.

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.

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.

Connective tissue disease--associated interstitial lung disease: an underreported cause of interstitial lung disease in Sub-Saharan Africa.

Interstitial lung disease (ILD) occurs in 15% of connective tissue disease (CTD) patients causing considerable morbidity and mortality. Data is scarce regarding its clinical characteristics and outcomes in Africa. We aim to study the frequency, clinico-radiological characteristics, and treatment outcomes of African CTD-ILD patients. A retrospective cross-sectional study of ILD among 318 CTD patients diagnosed using relevant ACR criteria at the rheumatology unit of Lagos State University Teaching Hospital (LASUTH), Lagos from 2012 to 2019. Socio-demographics, clinical features, radiological findings, and treatment outcomes were documented. Data was analyzed using SPSS version 21 with p < 0.05. The LASUTH ethics committee approved the study. Interstitial lung disease occurred in 31 (9.7%) of 318 CTD cases. Their mean age was 38.8 ± 13.3 years, range 19-68 years with 28 (90.3%) females. Proportions of CTD-ILD were Sjogren's syndrome (50%), UCTD (50%), systemic sclerosis (46.7%), MCTD (33.3%), PM/DM (25%), SLE (6.5%), and RA (2.6%). Commonest presentations were cough (93.5%) and bibasal inspiratory crackles (83.9%) with a restrictive pattern in 83.9%. Antinuclear antibody occurred in 100% and anti-ENA in 67.7%. Traction bronchiectasis (89.7%) and ground glass opacities (96.6%) were frequent HRCT findings. Treatments included pulse-dose prednisolone, cyclophosphamide, mycophenolate mofetil, pirfenidone, and rituximab. Outcomes were ambulatory oxygen therapy (12.9%) and mortality (16.1%) with 9.7% lost to follow-up. CTD-ILD is a female predominant disease occurring in 9.7% of CTD patients mostly those with Sjogren's syndrome and systemic sclerosis. Due to significant morbidity and mortality, we advocate routine ILD screening for all CTD patients including those with undifferentiated disease. Key Points: • Interstitial lung disease occurs in 9.7% of patients with underlying connective tissue disease. • Females are predominantly affected especially those with Sjogren's syndrome and systemic sclerosis. • Mortality occurs in roughly 1 in every 6 patients with CTD-ILD.

Tossing and turning with degenerative arthropathy: an assessment of poor sleep quality in knee osteoarthritis.

OBJECTIVES: To determine the frequency and predictors of sleep abnormalities among patients with knee osteoarthritis (OA) in Nigeria. MATERIAL AND METHODS: A multi-centre, hospital-based, cross-sectional study, involving 250 knee OA patients. Consenting patients 18 years and above, who satisfied the American College of Rheumatology (ACR) criteria for knee OA were recruited from five Nigerian tertiary centres over 3 months. An interviewer-administered questionnaire was used to collect demographic and relevant clinical information. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality with scores ≥ 5 indicating poor sleep. Other variables assessed were pain, depression, functional class and family functioning. Data were summarized using appropriate measures of central tendency and dispersion. Multiple logistic regression analysis was done to identify predictors of poor sleep. Analysis was done using SPSS version 21.0 with p < 0.05 considered significant. Study approval was obtained from the ethical committees of each of the study sites. RESULTS: Participants included 209 females (83.6%) with mean age 59.9 ±10.6 years. One hundred and forty-one participants (56.4%) had PSQI scores ≥ 5 (poor sleep). This was significantly associated with depression (p < 0.001), level of education (p = 0.001), higher pain scores (p < 0.001), body mass index (p = 0.040), medial knee OA (p = 0.032) and patello-femoral OA (p = 0.002). Higher level of education, worse depression scores and higher WOMAC pain scores were the best predictors of poor sleep quality. CONCLUSION: Sleep quality was poor in over half of our knee OA patients and best predicted by depression, pain and level of education. Regular sleep quality assessment for knee OA patients is recommended.

The Prevalence of Occult Hepatitis B Infection among Blood Donors in Lagos, Nigeria.

BACKGROUND: In occult hepatitis B virus (HBV) infection, the HBV DNA is present in the blood or liver tissue in patients negative for hepatitis B surface antigen (HBsAg) with or without anti-HBV antibodies. Thus, the absence of HBsAg in the blood only reduces the risk of transmission and is not sufficient enough to ensure the absence of HBV infection. AIM: This study was aimed at determining the prevalence of occult HBV infection among blood donors in Lagos. STUDY DESIGNS: A cross-sectional study was done among 101 consenting blood donors at Lagos State University Teaching Hospital, Ikeja, between November 2016 and January 2017. MATERIALS AND METHODS: HBV DNA analysis and viral load were done at the Molecular Laboratory of National Sickle Cell Centre, Idi Araba, Lagos, for all the HBsAg negative blood donors screened by rapid kit at Ikeja. RESULTS: The prevalence of occult HBV DNA among the participants was 3% consisting of 3% prevalence of HBV DNA surface antigen and 0% prevalence for precore and core of the HBV DNA. CONCLUSION: The low prevalence (3%) of occult HBV seen in our study does not make it cost-effective to routinely screen blood donors or the general population for HBV infection using DNA polymerase chain reaction.

Eosinophilic granulomatosis with polyangiitis in a Nigerian woman.

Eosinophilic granulomatosis with polyangiitis (EGPA), previously called Churg-Strauss Syndrome, is a systemic autoimmune disease that is usually associated with asthma and eosinophilia. It is a rare condition associated with antineutrophil cytoplasmic antibodies (ANCA). We report a case of a 52-year-old Nigerian woman who presented with bilateral leg swelling with multiple ulcers, background history of allergic rhinitis and chronic sinusitis since adolescence. There were also associated symptoms of peripheral neuropathy, weight loss, peripheral blood eosinophilia and positive perinuclear ANCA and she was previously managed for rheumatoid arthritis and asthma. She fulfilled the American College of Rheumatology criteria for EGPA and was treated with glucocorticoids and methotrexate which led to significant improvement of her symptoms.

How much gloom is in groans? Depression and its determinants in Nigerian patients with knee osteoarthritis: a multi-center cross-sectional study.

OBJECTIVES: To determine the prevalence of depression and its determinants among Nigerian patients with knee osteoarthritis (OA). METHODS: Two hundred and fifty patients satisfying the American College of Rheumatology classification criteria for knee OA were recruited from five centers. Pain was assessed using Western Ontario and McMaster Universities Index (WOMAC) pain subscale, functional status was determined by Steinbrokers criteria, radiographic knee OA was graded using Kellgren-Lawrence criteria, depression was determined using the Patient Health Questionnaire (PHQ-9), sleep quality by the Pittsburgh Sleep Quality Index (PSQI), and family functioning by Family APGAR (Adaptation, Partnership, Growth, Affection, and Resolve). Factors associated with depression in KOA following bivariate analyses were adopted as independent variables in logistic regression analysis to determine the predictors of depression in KOA. The study was approved by the Ethical Review Committee of each of the study centers. RESULTS: The mean age of patients was 59.90 ± 10.62 years and 209 (83.6%) were females. Their mean PHQ-9 score was 4.68 ± 4.19 with 105 (42%) having depression (PHQ-9 ≥ 5). Eighty-four (80%) of patients with depression had poor sleep quality (PSQI≥ 5.0). Depression was significantly associated with poor sleep, WOMAC pain scores, medial compartment KOA, lateral compartment KOA, and patellofemoral OA. Poor sleep quality was the best predictor of depression (OR 4.555, CI (2.241-9.257), p < 0.001) followed by moderate to severe pain (OR 2.490, CI (1.119-5.542), p < 0.025). CONCLUSION: Depression is common among patients with knee OA, and depression can be predicted by poor sleep quality and moderate to severe pain.

Recurrent spontaneous subcutaneous emphysema in a patient with rheumatoid arthritis.

Pulmonary air leak syndromes are extremely rare complications of systemic autoimmune connective tissue diseases and the occurrence of spontaneous subcutaneous emphysema (SSE) from pulmonary leak in the absence of pneumothorax or pneumomediastinum is even rarer. We report a case of recurrent SSE in a patient with rheumatoid arthritis and interstitial lung disease. The SSE was managed conservatively each time and it resorbed over several days. There has been no previous documented report of SSE in the absence of pneumomediastinum, pneumothorax or pulmonary nodules in a patient with RA.

Juvenile dermatomyositis in a Nigerian girl.

Juvenile dermatomyositis is an autoimmune connective tissue disease occurring in children less than 16 years old. It is part of a heterogeneous group of muscle diseases called idiopathic Iiflammatory myopathies. It had previously been reported in black Africans resident in UK. However, there is no documented case reported from Africa. The index sign of heliotrope rashes is often difficult to visualise in the black skin. An 11-year-old Nigerian girl presenting with clinical, laboratory and histopathological features of juvenile dermatomyositis is presented here. It is hoped that this case will heighten the index of suspicion of this condition among medical practitioners in Africa.

Digital gangrene as the initial presentation of systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) has rarely been reported among African blacks. However, recent reports may indicate otherwise. Digital gangrene in lupus patients has been reported in different populations and has mostly been seen in patients with long-standing lupus. Digital gangrene as the initial presentation of SLE has rarely been reported, even among African blacks. Two cases of digital gangrene as the initial presentation in Nigerian lupus patients are hereby presented. The medical and surgical managements, as well as relevant literature are hereby discussed.
