Dr. Ali A. Duarte Garcia is a rheumatology expert discussing the challenges of diagnosing systemic lupus erythematosus, often misidentified as other illnesses. He highlights its prevalence, especially among women and minorities, and identifies risk factors like UV exposure. The conversation covers essential early symptoms, distinctions between lupus and rheumatoid arthritis, and the latest advancements in treatment, including new biologics and the ongoing importance of hydroxychloroquine.
Systemic lupus erythematosus is particularly challenging to diagnose due to its diverse symptoms and the disease's mimicry of other conditions.
Effective management of lupus revolves around hydroxychloroquine usage for most patients, along with monitoring cardiovascular and renal health risks.

Understanding Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is a complex autoimmune disease that primarily affects women, especially those of reproductive age, and has higher incidence rates among minority groups, including Black, Hispanic, Asian, and Indigenous populations. Symptoms can be diverse, making it challenging to diagnose; often, patients experience conditions mimicking other diseases. Patients typically undergo periods of flares and remissions, which complicates management and treatment. The disease's heterogeneity is reflected in the variability of clinical manifestations, underscoring the need for thorough evaluation by primary care providers.
Key Clinical Manifestations and Diagnosis
Common presentations of lupus include arthritis, skin rashes, lupus nephritis, and hematological abnormalities such as leukopenia and thrombocytopenia, with joint pain predominantly affecting the hands. The well-known malar rash, while iconic, only occurs in about 20% of patients. Diagnosis often hinges on laboratory tests, particularly the presence of anti-nuclear antibodies (ANA) along with more specific anti-dsDNA and anti-Smith antibodies. Primary care providers should be alert to these symptoms when evaluating patients to facilitate timely referrals to rheumatology.
Management and Treatment Strategies
The cornerstone of lupus management is the use of hydroxychloroquine, which has been shown to reduce flare-ups and improve survival rates; it is recommended for nearly all patients unless contraindicated. Additional treatments may include corticosteroids and other immunosuppressants for more severe cases, while newer biologics are emerging as potential options. Close monitoring of cardiovascular health and renal function is essential, as lupus patients are at higher risk for cardiovascular events and lupus nephritis. Comprehensive care involves not only addressing lupus symptoms but also managing associated risk factors proactively.
Rheumatologic problems are some of the most common health conditions we see as primary care professionals. In many cases, taking months and sometimes years to properly diagnose, rheumatologic conditions can become frustrating for both the provider and the patient. There are a variety of new tests available to help us establish a diagnosis, as well as multiple new and effective treatment options. This episode is part of a seven-episode mini-series on Mayo Clinic Talks dedicated to rheumatologic health problems to aid in the recognition, diagnosis, and treatment for your patients.

Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease with a variety of immunological and laboratory abnormalities, as well as numerous clinical manifestations. It can affect almost every organ and has the potential to cause severe organ damage. Most patients experience flares of the disease alternating with periods of remission. Lupus is much more common in women than men and there are significant geographical and ethnic differences in the incidence and eventual outcome of the disease. It’s known as the great imitator because it can mimic a variety of other diseases and it’s not uncommon for patients to have symptoms for over 5 years, before a diagnosis of lupus is established. The topic for this podcast is systemic lupus and our guest is Ali A. Duarte Garcia, M.D., a rheumatologist from the Mayo Clinic.
