What Are the 4 Types of Lupus? First Signs

The four types of lupus are Lupus dermatitis, SLE, drug-induced lupus, and neonatal lupus.

Lupusis an autoimmune disease in which the immune system attacks healthy tissue. It affects the joints, skin, brain,lungs, kidneys, and blood vessels, leading to inflammation and tissue damage in the affected organs. When internal organs are involved, the condition is called systemiclupus
erythematosus (SLE).

The four types oflupusare:

1. Lupusdermatitis: Lupus affecting the skin in the form of arash.
2. Systemic lupus erythematosus(SLE): This type of lupus affects the internal organs and is the most serious type.
3. Drug-induced lupus: This type of lupus occurs as a result of an overreaction to certain medications such asApresoline(hydralazine) or奎尼丁and Pronestyl (procainamide). It is similar to SLE.
4. Neonatallupus: Lupus affecting an infant as a result of passively acquiring antibodies from a mother with SLE.

The exact cause of SLE is unknown, however, there are several risk factors that increase your chances of getting lupus, such as the following:

Genetic and hormonal factors may contribute to lupus

Environmental factors

• Exposure to UV rays
• 微生物的响应
• Certain medications
• Silica dust
• Cigarette smoking
• Photosensitivity(sensitivity to sunlight)

Other risk factors

• Family history of SLE
• Female sex
• Chronic infections
• Use of estrogen in women undergoingmenopause
• Vitamin D deficiency
• Pregnancyandbreastfeedinghave shown to decrease the risk of SLE.
• Women of childbearing ages (15-44 years)
• High-risk ethnic backgrounds such as African Americans, Asians, Hispanics, and Caucasians.

Early-life risk factors

• Low birth weight (<2,500 g)
• Preterm birth (birth that occurs before the 37th week ofpregnancy)
• Exposure to pesticides during childhood

Fatigue,fever,关节疼痛, and weight changes are usually the first signs of lupus. Some adults may have a period of SLE symptoms known as flares, which may occur frequently, sometimes even years apart and resolve at other times—called remission. Other symptoms include:

• Sun sensitivity
• Oral ulcers
• Arthritis
• Seizure
• Blood cell and immunological abnormalities
• Loss of appetite
• Muscle aches
• Alopecia(hair loss)
• Facialrash(butterfly rash)
• Chest paincaused due to inflammation of the lining that surrounds the lung (pleuritis) and theheart(pericarditis)
• Raynaud’s phenomenon (poor circulation to the fingers and toes withcoldexposure)
• Vasculitis(inflammation of blood vessels)

Apart from the above symptoms,nausea,indigestion,abdominal pain, andconfusionmay also be seen in some patients.

The complications that accompany lupus are as follows:

• Dysphagia(difficulty in swallowing)
• Lymphadenopathy(swollen lymph nodes)
• Lupoidhepatitis(liver disease)
• Fibromyalgia(muscle painand tenderness)
• Pancreatitis(inflammation in pancreas)
• Infections
• Coronaryheart disease(damage or disease in the heart’s major artery)
• Blood clots
• Kidney failure

Physicians diagnose lupus with the help of the following laboratory tests:

• Specific antibody tests for SLE (e.g., antinuclear antibodies)
• Complete blood cell count (CBC) to screen foranemiaandthrombocytopenia
• Serumcreatinineforkidney disease
• Urinalysisfor kidney disease
• Erythrocytesedimentation rate(ESR) andC-reactive protein(CRP) for inflammation
• Liver functiontests

Radiographic tests such as computed tomography scan,magnetic resonance imaging, and joint radiograph also detect abnormalities.

Ultimately, askin biopsyis performed to confirm the diagnosis.

There is no cure for lupus. Management of SLE depends on disease severity and disease manifestations.

Hydroxychloroquineis effective in the long-term treatment of SLE. Immunosuppressive medicines help to inhibit the activity of the immune system, which can also be useful in treating SLE.

Nonsteroidal anti-inflammatorydrugs(非甾体抗炎药) andcorticosteroidshelp to treat inflammation andpainin the muscles, joints, and other tissues.
