Introduction:
Systemic Lupus Erythematosus is a systemic immune disease that classically occurs in young to middle-aged women and may present with cutaneous, renal, hematologic, neurological, and/or other symptoms at the time of diagnosis. Late-onset Systemic Lupus Erythematosus or Systemic Lupus Erythematosus in the elderly is a subtype that differs from classic Systemic Lupus Erythematosus in terms of age group, clinical symptoms, organ involvement and severity.
Case presentation:
A 63 years old female noted to have pancytopenia. The patient was diagnosed with lupus upon obtaining clinical presentations and serological marker, along with high titers of the antinuclear antibody and/or anti-double-stranded DNA antibody. The patient was managed with glucocorticoids and mycophenolate mofetil therapy, which led to a rapid response.
Discussion:
Late-onset SLE accounts for 2–12% of SLE patients with a minimum age of onset of 50 years and older, leading to significant delays in diagnosis. Late-onset SLE differs from early-onset SLE in terms of gender and ethnicity prevalence, clinical symptoms and signs, development of organ damage, disease activity and severity, and prognosis .Some studies have also shown that late-stage SLE patients have higher rates of RF and anti-Ro/anti-La antibody positivity, lower complement titer, and higher incidence of elevated creatinine and decreased creatinine clearance .First-line treatment of pancytopenia is glucocorticoid. In refractory cases, rituximab and immunosuppressants can be used.
Conclusion:
It is important to assess any unusual presentation of Systemic Lupus Erythematosus when clinical suspicion remains high and conducting further laboratory and imaging investigation.
