Lupus (Systemic lupus erythematosus, SLE) is a chronic autoimmune disease where the body’s immune system mistakenly attacks its own healthy tissues and organs. While often associated with women, men can develop this condition.
Lupus Prevalence in Men
Lupus affects significantly more women than men, with a female-to-male ratio often cited as 9:1 or 10:1. Despite this disparity, men comprise a notable 10-20% of all lupus cases.
The reasons for this gender imbalance are not fully understood, but hormonal influences play a role. Estrogen may contribute to lupus development and severity, while androgens might have protective effects. Differences in X chromosome dosage and activity are also under investigation as potential contributors to the higher incidence in women.
How Lupus Manifests in Men
Lupus symptoms vary widely, but certain patterns are observed in men. General symptoms like fatigue, joint pain, and skin rashes are common in both sexes. However, men with lupus often experience a more severe disease course and greater organ involvement compared to women.
Specific internal organ systems are often affected more aggressively in men. This includes higher rates of kidney involvement (lupus nephritis), which can lead to poor kidney outcomes. Men may also experience increased instances of cardiovascular damage, serositis (inflammation of the lining around the lungs or heart), and neuropsychiatric issues like seizures. While typical lupus rashes can occur, men might have a lower incidence of the characteristic butterfly-shaped malar rash and hair loss, but a higher occurrence of discoid lupus.
The age of lupus onset can differ, with men often diagnosed at a later average age (around 40) compared to women (typically around 30). This later onset, particularly in cases classified as late-onset lupus (diagnosed after age 50), is more commonly seen in men. The disease may also present with atypical symptoms, where blood, kidney, or neurological signs appear before more common joint or skin symptoms.
Diagnosis and Management Considerations
Diagnosing lupus in men can present unique challenges, sometimes leading to delays. This occurs because lupus is often perceived as a “women’s disease,” which may lead healthcare providers to overlook it in male patients. The atypical presentation of symptoms in men can also contribute to diagnostic difficulties.
The diagnostic criteria for lupus, such as those from the American College of Rheumatology (ACR) or the European League Against Rheumatism (EULAR)/ACR, apply to both men and women. Diagnosis relies on a combination of clinical symptoms, physical examination, and various laboratory tests, including antinuclear antibody (ANA) tests and tests for specific autoantibodies like anti-dsDNA. A positive ANA test is common in lupus, but it is not definitive on its own.
Early diagnosis is important for managing lupus effectively and preventing severe organ damage. Management principles for men with lupus are generally similar to those for women, focusing on controlling inflammation and preventing organ damage. Treatment often involves anti-inflammatory medications, corticosteroids, antimalarials like hydroxychloroquine, and immunosuppressants. Given the potential for more severe disease in men, tailored care strategies that consider sex-specific differences are important.
A multidisciplinary approach involving rheumatologists and other specialists, depending on organ involvement, is often necessary. Men living with lupus can benefit from advocating for themselves, educating others about their condition, and seeking support resources. Open communication with healthcare providers and adherence to treatment plans are important aspects of long-term management.
