Abstract
Rhupus syndrome is an autoimmune disorder that combines the symptoms of lupus and rheumatoid arthritis. It is a rare condition that affects the connective tissues of the body such as the joints, muscles, and skin. The symptoms of rhupus syndrome can be similar to those of lupus, including joint pain, fatigue, and skin rashes. However, rhupus syndrome can also cause symptoms of rheumatoid arthritis, such as joint stiffness and swelling. Treatment for rhupus syndrome usually involves a combination of medications and lifestyle changes to manage symptoms and improve the overall quality of life. A 24-year-old female patient was referred by a local physician for evaluation of pancytopenia. Her history dates back to six months when she developed progressive fatigue, dyspnea on mild exertion, and polyarthralgia. Initial laboratory investigations revealed pancytopenia, positive antinuclear antibodies (ANA), anti-double-stranded DNA (anti-dsDNA), and anti-cyclic citrullinated peptide (anti-CCP) antibodies. Bone marrow examination confirmed the diagnosis of aplastic anemia. She was started on cyclosporine with an aim to maintain a trough level between 200 and 250 ng/mL. She responded well with hematological recovery in three to four months. This case highlighted the excellent response to cyclosporine hematologically and clinically in rhupus syndrome complicated with aplastic anemia. Further studies are required to establish the long-term efficacy of cyclosporine in this patient population.
