Non-scarring alopecia in systemic lupus erythematosus patients at the Lagos State University Teaching Hospital: a cross-sectional study of prevalence, pattern, trichoscopy features and histopathological analysis.

Introduction: trichoscopic and histopathological evaluation of non-scarring systemic lupus erythematosus (SLE) alopecia is uncommon. We aimed to document the prevalence, pattern of hair loss, trichoscopic and histopathologic differences between systemic lupus erythematosus patients with and without hair loss. Methods: this was a cross-sectional comparative study of 75 systemic lupus erythematosus patients, 36 with hair loss from February to December 2020. Trichoscopic evaluation was conducted on all 75 patients. Twenty-three patients (12 with hair loss and 11 without) had scalp biopsies with mucin deposit evaluation. Disease activity was documented using the SLE disease activity index. Data was analyzed using SPSS 22. Results: the mean age of the patients was 33.7 ± 12.4 years. Non-scarring alopecia was observed in 48%. The pattern of hair loss was <4 patches in 44.4%, mild diffuse in 25%, and severe diffuse in 30.6%. Disease activity was mild in 38.9%. Hair shaft changes included thin hair (97.2%), decreased number of hairs per follicular unit (97.2%), hypopigmented hair (85.7%), and follicular red dots (27.8%). Significant differences between the two groups were; a reduction in size and number of sebaceous glands on histopathology, hair shaft, and scalp pigmentary changes in the hair loss group. Conclusion: the prevalence of non-scaring alopecia is high in SLE patients with patchy type as the commonest pattern. Trichoscopic and histopathologic differences exist in SLE patients with and without hair loss and the normal-appearing scalp in SLE patients is involved in the inflammatory process. Hair shaft thinning, hypopigmentation, and scalp pigmentary changes occur in SLE.

Comorbidities in Nigerian patients with rheumatoid arthritis.

INTRODUCTION: Rheumatoid arthritis has been infrequently reported among African black populations. Recent data have shown increasing reportage. Comorbidities are increasingly recognised as important in the overall morbidity, mortality and response to management. There have been few reports from Africa on the frequency and role of comorbidities associated with rheumatoid arthritis (RA) in Africans. METHODS: This 20-year retrospective study looked at the frequency of various comorbidities among Nigerian patients with rheumatoid arthritis from a rheumatology facility. Data were obtained from the case record files of 283 RA patients. The chi-square test was used to assess the relationship between patient characteristics and the presence of comorbidity, while logistic regression was used to determine factors that were independently associated with the occurrence of comorbidities in these patients. RESULTS: The frequency of comorbidities among RA patients is high at 52.3%, mainly from common conditions such as hypertension (22.3%), dyslipidaemia (11.3%), osteoarthritis (8.1%), diabetes mellitus (7.1%), peptic ulcer disease (6.4%) and interstitial lung disease (3.5%). Increasing age (χ2 47.74, P<0.001) and prolonged duration of symptoms before diagnosis (χ2 9.0, P = 0.02) were significantly associated with the presence of comorbidity on univariate analysis, and only age was found to be independently associated with comorbidities on logistic regression. CONCLUSION: The frequencies of these comorbidities are similar in certain aspects to other such reports but differ from others. An important factor may be the delay in presentation to a rheumatologist. It is hoped that other more extensive studies will elucidate some of these findings.

Rheumatoid arthritis knowledge gap and intervention in Nigeria study.

INTRODUCTION: Family physicians are often the first healthcare providers to encounter patients with rheumatoid arthritis (RA) in Nigeria, given the paucity of rheumatology services nationwide. This study aimed to assess and address the knowledge gap regarding RA among family physicians in Nigeria. METHODS: A cross-sectional survey involving 609 family physicians from all six geopolitical zones of Nigeria was conducted in October 2022. Pre-intervention questionnaires were administered to assess the participants' knowledge of RA. An investigator-led PowerPoint presentation on RA was then delivered as an intervention, followed by the same participants completing post-intervention questionnaires to evaluate knowledge improvement. Data were analyzed using the Statistical Package for Social Science, version 25. RESULTS: The mean age of participants was 42 ± 15 years, predominantly male (63.9%). The median pre-intervention knowledge score was 3.2 (IQR: 2.0-4.5), with 77.0% scoring <5. After the intervention, the median score significantly improved to 7.1 (IQR: 4.3-8.6) (p = .001), with 62.6% scoring >7. Significant improvements were observed in several knowledge areas where gaps existed pre-intervention, including the understanding that NSAIDs are not the mainstay of management (p < .001), the effectiveness of glucosamine and chondroitin sulfate (p < .001), confidence in diagnosing RA (p = .016), the recognition of joint deformities as a characteristic feature (p < .001), and the understanding that rheumatoid factor is not definitive for diagnosis (p < .001). CONCLUSION: This study highlights the importance of interventions in closing the knowledge gap about RA diagnosis and management. We recommend the implementation of a comprehensive approach to rheumatology education and services by policymakers.

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.

Rheumatic diseases in Africa.

Historically, rheumatic diseases have not received much attention in Africa, particularly in sub-Saharan Africa, possibly owing to a focus on the overwhelming incidence of infectious diseases and the decreased life span of the general population in this region. Global attention and support, together with better health policies and planning, have improved outcomes for many infectious diseases; thus, increasing attention is being turned to chronic non-communicable diseases. Rheumatic diseases were previously considered to be rare among Africans but there is now a growing interest in these conditions, particularly as the number of rheumatologists on the continent increases. This interest has resulted in a growing number of publications from Africa on the more commonly encountered rheumatic diseases, as well as case reports of rare diseases. Despite the limited amount of available data, some aspects of the epidemiology, genetics and clinical and laboratory features of rheumatic diseases in African populations are known, as is some detail on the use of therapeutics. Similarities and differences in these conditions can be seen across the multi-ethnic and genetically diverse African continent, and it is hoped that increased awareness of rheumatic diseases in Africa will lead to earlier diagnosis and better outcomes for patients.

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.

Nurse-led care for the management of rheumatoid arthritis: a review of the global literature and proposed strategies for implementation in Africa and the Middle East.

Globally, increasing demand for rheumatology services has led to a greater reliance on non-physician healthcare professionals (HCPs), such as rheumatology nurse specialists, to deliver care as part of a multidisciplinary team. Across Africa and the Middle East (AfME), there remains a shortage of rheumatology HCPs, including rheumatology nurses, which presents a major challenge to the delivery of rheumatology services, and subsequently the treatment and management of conditions such as rheumatoid arthritis (RA). To further explore the importance of nurse-led care (NLC) for patients with RA and create a set of proposed strategies for the implementation of NLC in the AfME region, we used a modified Delphi technique. A review of the global literature was conducted using the PubMed search engine, with the most relevant publications selected. The findings were summarized and presented to the author group, which was composed of representatives from different countries and HCP disciplines. The authors also drew on their knowledge of the wider literature to provide context. Overall, results suggest that NLC is associated with improved patient perceptions of RA care, and equivalent or superior clinical and cost outcomes versus physician-led care in RA disease management. Expert commentary provided by the authors gives insights into the challenges of implementing nurse-led RA care. We further report practical proposed strategies for the development and implementation of NLC for patients with RA, specifically in the AfME region. These proposed strategies aim to act as a foundation for the introduction and development of NLC programs across the AfME region.

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.

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.

Fibromyalgia in a rheumatology clinic in north-central Nigeria: An audit of the characteristics of the syndrome and the sensitivities of 4 sets of American College of Rheumatology criteria.

OBJECTIVES: To describe the characteristics of fibromyalgia among Nigerian patients and assess the sensitivities of the American College of Rheumatology (ACR) criteria of 1990, 2010, 2011, and 2016 for making the diagnosis of fibromyalgia. METHODS: Consecutive patients diagnosed clinically with fibromyalgia by a rheumatologist were assessed. ACR criteria for fibromyalgia of 1990, 2010, 2011, and 2016 were applied to each patient. Polysymptomatic distress scores (PSD) were calculated from the Widespread Pain Index and Symptom Severity Scores. Sleep was assessed using the Pittsburgh Sleep Quality Index; fatigue by the Fatigue Severity Scale and the severity of fibromyalgia was determined using the Revised Fibromyalgia Impact Questionnaire (FIQR). RESULTS: A total of 660 new patients were seen out of which a diagnosis of fibromyalgia was made in 114 (17.3%). The mean age of the patients was 44.6 ± 15.6 years and females accounted for 84.2%. Twenty-one (18.4%) patients had changed or quit their jobs due to fibromyalgia. Problematic fatigue was present in 80 (70.2%), and sleep disturbance was reported in 83 (72.8%) patients. The severity of fibromyalgia, poor sleep, severe or very severe PSD, and male gender were associated with problematic fatigue, but only moderate/severe fibromyalgia independently predicted problematic fatigue (P = .004). The number of tender points (P = .001) and FIQR score (P = .038) were associated with changing or quitting jobs. The sensitivities of the ACR1990, ACR2010, ACR2011 and ACR2016 were 38.5%, 68.2%, 76.7% and 76.7%, respectively. CONCLUSION: The ACR1990 had low sensitivity when used to diagnose fibromyalgia in this population and the ACR2010 encounters problems while applying the somatic symptom list.

Case Series and Literature Review of Ophthalmologic Disorders Seen in a Specialist Rheumatology Clinic in Lagos, Nigeria.

Purpose: To highlight the pattern and treatment outcomes of ophthalmologic disorders referred to a private specialist rheumatology clinic. Methods: Retrospective review (January 2015-December 2016) of referrals from Eye Foundation Hospital, Lagos to Arthrimed Specialist Clinic, Lagos. Case records were retrieved and relevant information extracted. Ethical standards were observed. Results: Twenty-two referrals (35 eyes) were received out of 643 patients (3.4%) seen during the study period. The majority were female (63.6%) with mean age 48.9 ± 19.3 years and bilateral disease (59%). Diagnoses included uveitis (45.5%), optic neuritis (36.4%), non-specific autoimmune eye disease (9.1%), keratoconjunctivitis sicca (4.5%), and giant cell arteritis (4.5%). Treatment was with steroids and immunosuppressive agents. Fourteen patients improved (63.6%), five remained unchanged (22.7%), while three worsened (13.6%). Conclusions: Our patients were mostly fourth-decade females with bilateral disease. Uveitis was the commonest presentation, and two-thirds of the treated patients improved after treatment. Early specialist referral and co-management of severe autoimmune eye diseases are desirable.

Prevalence and Predictors of Chronic Kidney Disease in a Semiurban Community in Lagos.

BACKGROUND AND OBJECTIVES: The prevalence of noncommunicable diseases like chronic kidney disease is on the rise in third-world countries. In Nigeria and most sub-Saharan African countries, there is dearth of community-based studies on prevalence and predictors of chronic kidney disease, prompting us to undertake this study. MATERIALS AND METHODS: This was a cross-sectional study, aimed at ascertaining the prevalence and predictors of chronic kidney disease (CKD) in a semiurban community in Lagos, Southwest Nigeria. The study's subjects were recruited from Agbowa community in Ikosi-Ejirin Local Council Development Area of Lagos state. The community was randomly selected. Questionnaires were used to obtain relevant information from the subjects. Body mass index, anthropometric measurements, and other relevant data were also collected. RESULTS: CKD was observed in 30 subjects given prevalence of 7.5% in the community. Nine out of the 30 subjects (30%) with CKD were males, while 21 (70%) subjects were females. The prevalence of CKD was significantly higher in the female population. 28 of the subjects with CKD were in stage 3, while 2 of the subjects with CKD were in stage 4. Age, hypertension, and hyperuricemia were significantly associated with CKD. Using multiple logistic regression analysis, 4 variables predicted CKD in the study population. These were age (P =0.01, OR = 0. 274, CI = 0.102 - 0.739), hypertension (p = 0.011, OR = 0. 320, CI = 0.132 - 0.773), hyperuricemia (p=0.001, OR = 0.195, CI =0.083 - 0.461), and female sex (p = 0.009, OR = 3.775, CI = 1.401 - 10.17). CONCLUSION: The prevalence of CKD in the population is low compared with other studies from other parts of the country, and the predictors included age, hypertension, hyperuricemia, and female gender. This is the first community-based study in Nigeria to identify hyperuricemia as a risk factor for chronic kidney disease in the country.

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.

The impact of ocular manifestations of rheumatoid arthritis on the health-related quality of life and the functional ability of black Africans.

Objectives To determine the patterns, predictors and overall impact of ocular manifestations of rheumatoid arthritis (RA) on the health-related quality of life and disability index. METHODS: A total of 50 Nigerian patients with RA were studied. Full ocular evaluation was done to determine the presence of each defined ocular manifestation of RA. All patients completed the Medical Outcome Study 36-Item Short Form Health Survey (SF-36) and the Health Assessment Questionnaire-Disability Index (HAQ-DI) questionnaires. RESULTS: The mean ± SD age of the patients was 47.2 ± 12.5 years. A total of 42 cases of ocular diseases were found in 23 (46%) patients. Keratoconjunctivitis sicca was found in 15 (30%) patients; cataract, 13 (26%); scleritis/episcleritis, 4 (8%); disk edema, 4 (8%); glaucoma, 3 (6%); ulcerative keratitis, 1 (2%); vitreitis, 1 (2%); and macula edema, 1 (2%) patient. There is an association of the presence of ocular manifestations with the physical component summary (PCS) [T = - 3.398, P = 0.001] and the mental component summary (MCS) [T = - 2.616, 0.012] of the SF-36 but not with the HAQ-DI (T = 1.685, 0.099). Following multiple regression analysis, the predictors of the presence of ocular manifestations were age greater than 45 years and positive anti-citrullinated protein antibody. Following linear regression analyses, Steinbrocker's functional class independently predicted the PCS while both Steinbrocker's functional class and female sex predicted the MCS. CONCLUSIONS: The development of ocular disorders associated with RA is associated with a significant negative impact on the quality of life of the patients.

Frequency and associations of chronic kidney disease among gout patients from a University Teaching Hospital in Nigeria.

OBJECTIVES: To highlight common precipitants and co-morbidities of gout in Nigerians; determine the frequency of chronic kidney disease (CKD) in Nigerian gout patients, as well as identify significant associations of CKD in gout patients. MATERIAL AND METHODS: Retrospective cross-sectional study of gout cases seen at the Rheumatology Clinic of the Lagos State University Teaching Hospital over five years from January 2011 to December 2015. Gout was diagnosed using the 1977 American Rheumatism Association (ARA) criteria. Clinical and laboratory data were extracted and examined for the presence of CKD defined using Kidney Disease Improving Global Outcomes (KDIGO) 2012 guidelines as estimated glomerular filtration rate (eGFR, CKD-EPI) < 60 mls/min/1.73 m2 body surface area for > 3 months. RESULTS: One hundred and six gout patients were identified representing 4.5% out of a total of 2330 cases seen during the study period. There were 94 males and 12 females. Oligoarthritis was most frequent (41.5%) with the knee mostly affected (20.1%). Diuretic use was the most frequent precipitant (37.9%) with hypertension the commonest co-morbidity (62.9%). Of 70 patients with complete results, 29 had eGFR (CKD-EPI) < 60 mls/min (41.4%). Age, proteinuria, body mass index (BMI) and packed cell volume (PCV) were significant associations of CKD. Gout patients with CKD were significantly older (61.79 vs. 54.41 years, p = 0.003) with a significantly higher proportion developing proteinuria (15 vs. 4 patients, p ≤ 0.0001) compared to those without CKD. In contrast, those with CKD had a significantly lower BMI (27.31 vs. 29.65 kg/m2, p = 0.026) and PCV (31.97 vs. 37.95%, p = 0.005). CONCLUSIONS: Thiazide diuretic use is the most common precipitant while hypertension is the commonest comorbidity in Nigerian gout patients. About two in five Nigerian gout patients had chronic kidney disease at presentation with age, proteinuria, BMI and PCV as significant associations. It is thus imperative to screen for chronic kidney disease when managing gout patients.

Psoriatic Arthritis in Nigeria: Case Series and Literature Review.

BACKGROUND: Psoriatic arthritis (PsA) is an extracutaneous manifestation of psoriasis occurring in 6% to 42% of patients. Both conditions are common among whites but rarely reported among black Africans.Few African studies, however, have reported PsA frequencies of 0% to 4.6%, with a previous case report of 2 patients from a Nigerian rheumatology clinic. METHODS: Case records of PsA patients from the Lagos State University Teaching Hospital Rheumatology Clinic seen over a 5-year period from January 2012 to December 2016 were retrieved and documented.Psoriatic arthritis was diagnosed using the Classification Criteria for Psoriatic Arthritis. Data on demography, clinical features, laboratory parameters, imaging, and treatment were extracted from case records. RESULTS: Twelve PsA cases were identified out of 2330 patients (0.5%) seen during the study period. There were 9 males and 3 females. Age range was 24 to 67 years (mean, 45.3 ± 15.1 years). Duration of psoriasis ranged between 11 and 96 months (mean, 46.8 ± 33.6 months), whereas median duration of arthritis at presentation was 15 months (range, 4-72 months).Oligoarthritis was the commonest presentation (58.3%). Dactylitis (66.7%) and enthesitis (44.7%) were frequent extra-articular features. All patients were negative for rheumatoid factor and human immunodeficiency virus. HLAB27 was negative in 5 patients tested.Treatment was mostly with nonsteroidal anti-inflammatory drugs (100%) and methotrexate (75%). Only 1 patient received the biologic etanercept. Eight subjects (66.6%) showed initial improvement in skin and joint symptoms, of which 6 had a relapse within 6 to 12 months. CONCLUSIONS: Psoriatic arthritis is rare among Nigerians and predominantly affects males in their fourth decade. Oligoarthritis is common, and extra-articular manifestations are frequent.
