AbstractData on characteristics of neuropathic pain (NP) in sub-Saharan Africa are scarce, especially in the elderly. We conducted this study to appreciate the socio-demographic and clinical profile of chronic pain (CP) with neuropathic characteristics in sub-Saharan African elderly with musculoskeletal pain. From January to December 2011, we performed a cross-sectional study in all Rheumatology outpatients over 60 years at the Center for Gerontology and Geriatrics, Dakar, Senegal. In this study, we included patients who experienced musculoskeletal pain for 3 months or longer (CP) and with a DN4 score ≥ 4 (NP). A complete clinical examination was performed to make the diagnosis of NP 'definite' or 'probable', and to identify the aetiologies of NP. During the study period, 698 outpatients were examined. There were 394 out of the 549 patients over 60 years who reported CP. Among them, 28 patients (7.1%) scored ≥4 on the DN4 questionnaire. Female patients, low educational attainment, manual professions, non-workers and diabetes were associated with NP (p < 0.05). The symptoms described by patients with NP, often intricate, were lumboradiculalgia (n = 9), cervico-brachial neuralgia (n = 3), polyneuropathy (n = 12) and mononeuropathy (n = 6). The presumed aetiologies in patients with NP were: chronic spine diseases (n = 14), painful diabetic peripheral neuropathy (n = 8), Sjögren's syndrome (n = 1), tarsal tunnel syndrome in rheumatoid arthritis (n = 1) and bone metastasis (n = 1). No aetiology was identified among three patients. Chronic spine diseases associated with radiculopathies and diabetic neuropathy are the main causes of NP, well detected by DN4 questionnaire and clinical examination in Senegalese sub-Saharan African elderly.© 2012 European Federation of International Association for the Study of Pain Chapters.
