Lupus Erythematosus

Lupus Erythematosus is a chronic autoimmune disease in which the body’s immune system attacks its own structures, causing inflammation in various tissues and organs. The disease belongs to the group of collagen vascular diseases, where misregulation of the immune system primarily affects connective tissue. Lupus occurs worldwide, with women being approximately nine times more frequently affected than men, particularly between the ages of 15 and 45. The disease is also more prevalent in certain ethnic groups, such as African Americans, Asians, and Latin Americans, where it often presents in more severe forms. The autoimmune reaction in lupus leads to an excessive immune response against the body’s own proteins, especially collagen. This triggers chronic inflammation that can manifest as skin changes, joint problems, or more serious organ involvement. Depending on the severity, different forms of Lupus Erythematosus are distinguished.

Systemic Lupus Erythematosus (SLE) is the most common and severe form, as it can affect not only the skin but often also internal organs such as the kidneys, heart, or nervous system. Cutaneous Lupus Erythematosus (CLE) primarily affects the skin, as indicated by its name, and manifests through inflammatory rashes that often occur after sun exposure. A special subtype is Discoid Lupus Erythematosus (DLE), which causes sharply defined, scarring skin lesions. Diagnosis and treatment are therefore based on the specific form and individual progression of the disease.

Lupus Erythematosus can occur in various forms that differ significantly in severity, symptoms, and organ involvement. While some variants predominantly affect the skin, other forms also attack internal organs. The specific form of the disease therefore determines the course and treatment options. In addition to the direct effects of lupus, other accompanying conditions can also occur, facilitated by chronic inflammation or drug therapy. A common complication is osteoporosis, as many lupus patients develop accelerated bone loss due to inflammation or long-term cortisone treatment. Furthermore, Sjögren’s syndrome often occurs concurrently, an autoimmune disease that primarily targets the salivary and tear glands, leading to dry mucous membranes. In the following sections, we will explain the different forms of lupus in more detail to better illustrate the differences in diagnosis, progression, and therapy.

Systemic Lupus Erythematosus (SLE) is the most common and severe form of lupus, as it typically affects multiple organ systems. This form of the disease progresses in flares, with periods of remission and acute inflammation. A characteristic clinical presentation of SLE is the butterfly rash, a reddish skin eruption that spreads across the nose and cheeks. Additional skin manifestations include photosensitive rashes, mucosal lesions, and in some cases, hair loss. What makes SLE so severe is that it rarely remains confined to the skin. It is frequently characterized by inflammation of the joints (arthritis), kidneys (lupus nephritis), and the cardiovascular system, which can significantly increase the risk of thrombosis or myocarditis. The central nervous system can also be affected in SLE, manifesting as headaches, cognitive dysfunction, or even seizures. The exact causes of SLE are not yet fully understood, but various trigger factors can precipitate disease flares. These include UV radiation, hormonal changes such as during pregnancy or with estrogen therapy, infections, severe stress, and certain medications. Genetic factors often play a role, as SLE can be observed with increased frequency in some families. The systemic responses of SLE are typically diverse and can lead to serious complications. Since the disease course of SLE is highly individual, treatment often requires a personalized therapeutic approach that may include anti-inflammatory medications, immunosuppressants, and symptom-oriented measures. The main goals are to prevent flares, minimize organ damage, and improve patients’ long-term quality of life.

Cutaneous Lupus Erythematosus (CLE) is a form of lupus that primarily affects the skin and, unlike systemic lupus erythematosus, does not involve internal organs. The disease manifests through inflammatory skin changes that are often exacerbated by sun exposure. One of the most well-known manifestations, even in this form of lupus, is the butterfly rash, a symmetrical, reddish skin eruption that extends across the nose and cheeks. In addition to this characteristic appearance, CLE frequently presents with other skin-related symptoms, including scaly, discoid skin lesions, particularly on the face, ears, and scalp. In some cases, these lesions may leave scars or pigmentation changes. UV radiation plays a central role in the disease progression, as sunlight can trigger flares or worsen existing skin manifestations. Therefore, affected individuals are strongly advised to use consistent sun protection. Unlike systemic lupus, CLE typically remains confined to the skin and does not lead to involvement of other organs. Nevertheless, there can be fluid transitions between the different forms of lupus.

Discoid Lupus Erythematosus (DLE) is a chronic inflammatory skin disease that belongs to the cutaneous lupus erythematosus group. It is characterized by well-defined, disc-shaped (discoid) skin lesions that primarily appear on the face. These skin lesions often begin as reddish, raised patches that become keratotic and scaly over time. In more advanced stages, they can leave scars and pigmentation changes, which may lead to permanent skin damage. UV sensitivity also plays a central role in DLE, as sun exposure frequently leads to worsening of symptoms. Therefore, consistent sun protection is an essential component of therapy. Unlike systemic lupus, DLE typically remains confined to the skin; however, in some cases, there is a risk that the disease may progress to systemic lupus erythematosus.

Lupus Erythematosus can cause a variety of symptoms as the disease attacks the immune system, various tissues, and organs. The complaints are therefore individually different and range from mild skin changes to severe systemic organ involvement. Particularly typical is the episodic course. This involves phases with severe symptoms that alternate with calmer periods. While lupus in women often manifests through skin changes, joint pain, and extreme fatigue, men tend to develop more severe organ involvement, particularly of the kidneys and cardiovascular system.

Typical symptoms of lupus include:

Since lupus can affect many organ systems, early diagnosis is of great importance to avoid complications and to control the symptoms as effectively as possible.

The diagnosis of Lupus Erythematosus consists of a comprehensive examination, as the symptoms are often very diverse and the disease can affect many organ systems. Therefore, early diagnosis is crucial to avoid severe organ damage and improve the quality of life of the affected person. The diagnostic process usually consists of several steps that include both clinical and laboratory examinations.

The first step in diagnosis is a thorough medical history, inquiring about symptoms that could indicate lupus. The clinical examination focuses on typical signs such as skin changes, joint inflammation, or examination of internal organs.

Blood tests are an important component of diagnosis. The so-called ANA test (antinuclear antibodies) is a fundamental test to check for the presence of antibodies that are detectable in many lupus diseases. Other typical blood values in lupus include an elevated erythrocyte sedimentation rate (ESR) and changes in liver and kidney values, which may indicate inflammatory activity. Additional specific autoantibodies, such as anti-dsDNA or anti-Smith, can help confirm the diagnosis of lupus.

If cutaneous forms of lupus are suspected, such as discoid lupus or systemic lupus with skin involvement, a skin biopsy may also be performed. In this procedure, a small skin sample is taken and examined more closely under the microscope for characteristic signs of inflammation.

In addition to laboratory tests, imaging procedures and kidney function tests may be necessary if systemic involvement, such as lupus nephritis, is suspected. An accurate diagnosis of the lupus form is important to initiate individually tailored treatment and avoid possible complications.

The exact causes of Lupus Erythematosus are not yet fully understood, but both genetic and environmental factors play a decisive role in the development of the disease. A significant risk factor for lupus is genetic predisposition. In families where lupus cases have occurred more frequently, the risk of developing the disease oneself is increased. Certain genes that affect the immune system can contribute to the onset of the disease, especially in conjunction with other environmental factors.

Environmental influences often include UV light, certain infections, or stress. These are considered trigger factors that can initiate or worsen the course of the disease. UV radiation, especially sunlight, has a particularly negative impact on people with lupus. Viral infections, such as the Epstein-Barr virus, have also been associated with an increased risk of lupus.

The significant gender differences in the incidence of lupus provide evidence that hormonal influences, particularly estrogens, may play a role in the development of the disease.

Another risk factor is immunodeficiency, such as that which can occur with certain diseases like HIV or through immunosuppressive therapies. These conditions can increase the risk of the immune system losing control and developing autoimmune reactions like those seen in lupus.

Finally, chronic toxin exposure, such as from mercury or tobacco smoke, can increase the risk of developing lupus. These environmental pollutants can damage the immune system and promote inflammatory processes in the body.

In summary, lupus can be caused by complex interactions of genetic predispositions, environmental factors, and gender-specific influences. The exact mechanisms are not yet fully understood, but it is clear that a combination of several factors is necessary for the disease to manifest.

The treatment of Lupus Erythematosus aims to effectively control inflammation, reduce disease activity, and prevent organ damage. Since it is a chronic autoimmune disease that can affect different organ systems, individualized therapy is necessary. The treatment approach is therefore typically multimodal and includes both medication therapies and lifestyle changes. Typical treatment strategies include anti-inflammatory medications such as Nonsteroidal Anti-inflammatory Drugs (NSAIDs) to relieve joint pain and skin rashes, as well as antimalarial agents like hydroxychloroquine, which can particularly alleviate skin and joint symptoms. In more severe cases, immunosuppressants may also be used to slow down the overactive immune system. In some cases, biologics are employed to more specifically inhibit inflammatory processes.

Despite these diverse therapeutic options, treatment often faces limitations, especially in managing severe organ involvement or controlling disease flares. Treatment therefore requires regular monitoring and adjustment of medication, as many of the drugs can also have additional side effects that may affect quality of life. The following section will explain the individual treatments in detail to provide a better understanding of the therapeutic options and their limitations.

Conventional medical treatment of Lupus Erythematosus primarily focuses on controlling inflammation and regulating the overactive immune system. A central component of therapy is therefore immunosuppressants, which suppress the immune system to protect the body’s own cells from further attacks. Commonly used immunosuppressants include hydroxychloroquine, which is primarily used in mild to moderate forms of lupus, and methotrexate, which is used in more severe cases, especially when organs such as the kidneys or heart are affected. Another important component of therapy is corticosteroids, which, due to their strong anti-inflammatory effect, are quickly used in acute phases to reduce inflammation and alleviate symptoms. Non-steroidal anti-inflammatory drugs (NSAIDs) are also used to relieve joint pain and inflammation, but only in less severe cases. In severe cases of lupus, especially when serious organ involvement occurs, biologics are increasingly being used. These biologics are an important extension of treatment options, particularly when other medications are not sufficiently effective. Overall, conventional medical approaches offer a variety of options for controlling and treating lupus; however, regular adjustment of therapy is essential as the disease progresses individually and can change over time.

In addition to conventional medical treatment, holistic approaches can offer valuable complementary therapy. These can support the reduction of inflammation, stabilize the immune system, and improve overall well-being. These methods focus particularly on nutrition, lifestyle optimization, detoxification, orthomolecular medicine, and the elimination of hidden inflammation.

Conscious nutrition can play a crucial role in regulating immune response. Antioxidant-rich foods, such as berries, leafy greens, and nuts, help reduce oxidative stress, which plays an exacerbating role in lupus. Anti-inflammatory foods like turmeric, ginger, and omega-3-rich foods also support the reduction of systemic inflammation. Avoiding pro-inflammatory foods such as refined sugar, processed fats, and gluten can help minimize disease flares.

Stress is a common trigger factor for lupus flares, so stress management techniques such as meditation, yoga, and breathing exercises are essential to calm the nervous system and regulate the immune system. Similarly, good UV protection is of great importance, as many lupus patients have increased photosensitivity that can exacerbate skin changes and systemic inflammation. Using sunscreens with high UV filters, protective clothing, and avoiding direct sunlight are therefore very important to prevent possible intensification of inflammation.

Many lupus patients often suffer from joint problems and muscle weakness. Regular physiotherapy can help maintain joint mobility, relieve pain, and prevent premature muscle deterioration. Gentle forms of exercise such as swimming or gentle strength training can relieve joint stress while strengthening the body.

Furthermore, chronic exposure to environmental toxins such as heavy metals or other toxins can place additional strain on the immune system. Therefore, detoxification measures are often used to support the elimination of pollutants. Liver detoxification can be promoted, for example, by milk thistle, bitter substances, and adequate fluid intake. Heavy metals can also be removed from the body through chelation therapies or special procedures such as INUSpheresis. This filters the blood to specifically remove harmful substances while preserving important blood proteins and nutrients. This method can relieve the immune system and is particularly used for chronic inflammation and autoimmune diseases.

In addition to the influence of harmful substances, a disturbed gut flora can also dysregulate the immune system and promote the development of inflammation. Colon cleansing can help restore the balance of intestinal bacteria. Probiotics, fiber, and gut-friendly nutrition with fermented foods support a healthy microbiome, which can positively affect the immune system. A healthy gut plays a crucial role in maintaining a strong immune system, as approximately 70% of immune cells are located in the gut. Therefore, a balanced gut flora supports the defense against pathogens, the regulation of inflammatory processes, and the promotion of absorption of essential nutrients for immune function.

Micronutrients also play a central role in immune regulation. In orthomolecular medicine, vitamins, minerals, and fatty acids are specifically used to reduce inflammation and promote cellular health. Omega-3 fatty acids have anti-inflammatory effects, vitamin D is essential for immune modulation, and a deficiency in vitamin D can be associated with increased disease activity. Zinc, selenium, and vitamin C also contribute to stabilizing the immune system.

Chronic silent inflammations, such as those caused by jaw inflammation or periodontitis, can excessively activate the immune system and intensify autoimmune reactions. Therefore, regular dental check-ups and targeted treatments of hidden infections can help reduce the systemic inflammatory load.

Holistic approaches can often effectively complement conventional medical therapy and help reduce flare-ups, regulate the immune system, and improve overall quality of life. An individually tailored combination of nutrition, detoxification, micronutrients, stress management, and physical activity can provide supportive benefits.

The prognosis of Lupus Erythematosus depends significantly on the course of the disease and individual treatment. A timely diagnosis and well-adjusted therapy can considerably improve quality of life and slow down the progression of the disease. While lupus was often a severely limiting condition in the past, modern treatment strategies have significantly increased the life expectancy of those affected. Today, the 5-year survival rate is over 90%, while the 10-year survival rate is approximately 85%. In well-controlled cases, where inflammation is effectively contained and no serious organ damage occurs, patients can live for many years with a good quality of life. Crucial factors include consistent treatment, avoidance of known trigger factors, and regular check-ups.

The course is more severe in patients with significant organ involvement, especially when vital organs such as kidneys, heart, or lungs are affected. In such cases, the disease can cause serious complications that often considerably worsen the prognosis. There is also an increased risk with frequent and intense disease flares, which can heavily strain the immune system and leave long-term damage.

Early diagnosis and individually tailored therapy are therefore essential to prevent severe organ damage. Regular medical check-ups can also help to optimally control the disease and positively influence the prognosis.
