Systemic lupus erythematosus (SLE) is a multisystem autoimmune rheumatic disease (ARD) that results from the dysregulation of multiple innate and adaptive immune pathways. Late-onset SLE (Lo-SLE) is the term used when the disease is first diagnosed after 50-65 years, though the standard age cut-off remains undefined. Defining "late-onset" as lupus with onset after 50 years is more biologically plausible as this roughly corresponds to the age of menopause. Lo-SLE comprises nearly 20% of all cases of lupus. With advancing age, the female predominance of lupus declines to nearly 4:1 to even 1.1:1. The natural history of the disease varies, with lesser major organ involvement like nephritis but higher damage accrual. The latter is possibly owed to the atypical presentation and hesitation among physicians to diagnose SLE at this age, a diagnostic delay with late treatment initiation may accelerate the damage accrual. Multimorbidity is a central issue in these patients, which includes osteoporosis, sarcopenia, accelerated atherosclerosis in the background of existing dyslipidemia, diabetes mellitus, major depression, hypertension, coronary artery disease and other thrombotic events.With the rising ages of populations worldwide, awareness about late-onset lupus is paramount, especially due to the associated diagnostic delays and higher overlap with Sjogren's disease. Also, pharmacotherapeutics must be optimized considering factors associated with ageing like declining glomerular filtration rate (GFR), sarcopenia, osteoporosis, and the associated comorbidities. Measures to minimize the exposure to long-term exposure to high-dose steroids are crucial. Beyond this, it is of essence to adopt non-pharmacological interventions as an adjunct to traditional immunosuppression to improve pain, fatigue, depression, and anxiety, improve cardiovascular health and overall better quality of life with favourable long-term outcomes.
