Hidden lupus: study reveals why atypical cases are often missed
NCT ID NCT07350772
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 400 people with lupus to compare those with typical symptoms versus those with unusual or 'atypical' symptoms. The goal is to understand how these differences affect disease activity, organ damage, and treatment needs over time. By identifying these patterns, doctors hope to diagnose and treat atypical lupus earlier and more effectively.

Inclusion Criteria: Patients diagnosed as SLE according toSLICC 2012Classification Criteria\[13\] : A. Patients presented with typical lupus presentation: 1. age of onset (20-50) 2. common initial manifestations as constitutional manifestations,arthritis, mucocutaneousmanifestationslike malar rash, photosensitivity and hair falling. 3. patients with ANA positive. B. Patients presented with atypical lupus presentation: 1. any clinical presentation not belonging to classic common SLE onset features, including but not limited to: * Neuropsychiatric onset: seizure, psychosis, aseptic meningitis, transverse myelitis * Cardiopulmonary onset: pulmonary hypertension, acute pneumonitis, myocarditis, pulmonary hemorrhage * Gastrointestinal onset: mesenteric vasculitis, intestinal pseudo obstruction, pancreatitis * Hematologic severe onset: isolated severe thrombocytopenia, autoimmune hemolytic anemia, thrombotic microangiopathy * Dermatologic atypical onset: bullous lupus, panniculitis, vasculitic ulcers * Myositis * Fever of unknown origin (FUO) as sole initial presentation * Thrombotic events * Generalized lymphadenopathy. 2. Patients with dominant organ affection. 3. patients with late onset SLE. 4. patients with ANA negative SLE. C.Patients who can provide informed consent. exclusion criteria: 1. Patients whose initial symptoms are clearly attributable to infection, sepsis or another non-SLE condition. 2. Patients with chronic pre-existing diseases that may mimic or obscure the initial SLE presentation (e.g. primary epilepsy, primary pulmonary hypertension, chronic liver or GI disease). 3.
