| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What is the classic demographic most affected by SLE? | SLE predominantly affects women of childbearing age, especially those of African, Hispanic, Asian, or Native American descent. | Think of the typical gender and age group for autoimmune diseases. |
| 2 | Name the four main clinical features of the classic SLE presentation (the 'SOAP BRAIN MD' mnemonic). | Serositis, Oral ulcers, Arthritis, Photosensitivity, Blood disorders, Renal involvement, ANA positivity, Immunologic phenomena, Neurologic symptoms, Malar rash, Discoid rash. | Mnemonic aids in recalling key features. |
| 3 | What are the common autoantibodies associated with SLE? | ANA (antinuclear antibody), anti-dsDNA, anti-Smith (Sm), antiphospholipid antibodies. | Think of antibodies targeting nuclear components and antiphospholipid antibodies for clot risk. |
| 4 | Which autoantibody is most specific for SLE? | Anti-dsDNA antibodies are highly specific for SLE and correlate with disease activity, especially renal involvement. | Focus on specificity for diagnosis. |
| 5 | What is the role of ANA testing in SLE diagnosis? | ANA positivity is present in over 95% of SLE patients, making it a sensitive but not specific test; it supports diagnosis but is not definitive alone. | Think of ANA as a screening tool. |
| 6 | What are the American College of Rheumatology (ACR) classification criteria for SLE? | A patient is classified as having SLE if at least 4 of 11 criteria are met, including malar rash, discoid rash, photosensitivity, oral ulcers, arthritis, serositis, renal disorder, neurologic disorder, hematologic disorder, immunologic disorder, and ANA positivity. | Criteria are used for classification, not diagnosis. |
| 7 | Name two key laboratory findings indicative of active SLE renal disease. | Proteinuria (>0.5 g/day) and cellular casts in urine (e.g., red blood cell casts). | Think of urine findings pointing to nephritis. |
| 8 | What is the first-line treatment for mild SLE flares? | NSAIDs and hydroxychloroquine are commonly used for mild disease activity. | Think of medications that control symptoms and modify disease. |
| 9 | Which immunosuppressive agents are used for severe SLE manifestations like lupus nephritis? | Cyclophosphamide, mycophenolate mofetil, and azathioprine are commonly employed. | Targeted immunosuppression for organ-threatening disease. |
| 10 | What is the role of hydroxychloroquine in SLE management? | Hydroxychloroquine reduces disease activity, prevents flares, and decreases thrombotic risk; it is a cornerstone of SLE therapy. | Think of it as disease-modifying and protective. |
| 11 | Which medication is contraindicated in SLE patients with active renal disease due to its potential nephrotoxicity? | Methotrexate is generally avoided in active nephritis; instead, immunosuppressants like mycophenolate are preferred. | Focus on nephrotoxic potential. |
| 12 | What are common cutaneous manifestations of SLE? | Malar rash, discoid rash, photosensitivity, and livedo reticularis. | Skin signs often follow sun exposure. |
| 13 | How does antiphospholipid syndrome relate to SLE? | Antiphospholipid antibodies are common in SLE and increase the risk of arterial and venous thrombosis; management may include anticoagulation. | Think of clotting disorders in autoimmune context. |
| 14 | What is the significance of complement levels (C3, C4) in SLE? | Decreased complement levels often indicate active disease, especially during flares involving the kidneys or other organs. | Complement consumption reflects immune complex activity. |
| 15 | Which drugs are used to manage SLE-induced arthritis? | NSAIDs and corticosteroids; immunosuppressants in severe cases. | Anti-inflammatory agents first line. |
| 16 | What are common neuropsychiatric manifestations in SLE? | Seizures, psychosis, cognitive dysfunction, cerebrovascular disease. | Think of neuro and psychiatric symptoms as part of 'NPSLE'. |
| 17 | What is the main goal of SLE treatment? | To control disease activity, prevent organ damage, and reduce flares. | Think of it as long-term disease suppression. |
| 18 | Name a key non-pharmacologic measure in SLE management. | Sun protection to prevent photosensitive rashes and disease flares. | Sunlight triggers skin manifestations. |
| 19 | Why is regular monitoring essential in SLE patients? | To detect disease activity, monitor medication side effects, and prevent organ damage. | Ongoing assessment guides therapy adjustments. |
| 20 | What is the significance of antiphospholipid antibodies in SLE? | They increase the risk of thrombotic events and pregnancy complications; management may include anticoagulation. | Think clot risk in autoimmune patients. |
