14796 Systemic Lupus Erythematosus Sle In Children

Overview

Systemic lupus erythematosus (SLE), commonly called lupus, is a condition where the immune system, which normally fights off infections, mistakenly attacks healthy parts of the body. This can cause inflammation (swelling and irritation) in the skin, joints, kidneys, and other organs. In children, it often requires long-term care and support.

Lupus is not common in children. It is estimated that fewer than 1 in 100,000 children develop it each year. Most people who have lupus are women, and the condition usually starts in adulthood.

Lupus can start at any age, but it is most often diagnosed in girls and young women. In children, it usually appears after age 5, and more commonly during the teenage years. Boys can develop lupus too, but it is less common.

Symptoms

Common symptoms

• Extreme tiredness (fatigue) that does not get better with rest
• Joint pain and swelling
• A red rash across the cheeks and nose, sometimes called a butterfly rash
• Unexplained fever
• Hair loss or thinning
• Sensitivity to sunlight

Symptoms in children

• Slower growth or delayed puberty
• Kidney problems, which can show up as blood or protein in the urine
• Mood changes or trouble concentrating
• Abdominal pain or nausea

Causes

Main causes

• The exact cause of lupus is not known. It seems to involve a combination of genetic factors (genes inherited from parents) and environmental triggers.
• In people with lupus, the immune system loses its ability to tell the difference between healthy tissue and foreign invaders like bacteria and viruses.
• Hormones may also play a role, which may explain why lupus affects more females than males.

Risk factors

• Being female
• Having a family history of lupus or other autoimmune conditions
• Certain infections or environmental exposures, like ultraviolet light from the sun

When to see a doctor

See a doctor urgently if:

• See a doctor urgently if your child has any of the urgent symptoms listed above (such as severe abdominal pain or blood in urine).

Book a routine appointment if:

• Make a routine appointment if your child has ongoing tiredness, joint pain, or a rash that does not go away, so a doctor can assess the symptoms.

Diagnosis

A doctor will take a detailed medical history, do a physical exam, and use blood and urine tests. Because symptoms vary, lupus can be difficult to diagnose. You will likely be referred to a specialist called a paediatric rheumatologist (a doctor who treats conditions that affect joints and immune system in children).

Tests that may be done

• Antinuclear antibody (ANA) test – a blood test that is often positive in people with lupus
• Other blood tests to check for inflammation and levels of immune system cells
• Urine tests to check for kidney problems
• Complete blood count (CBC) to look for anaemia or low blood cell counts

What to expect at your appointment

The doctor will explain each test and what it looks for. It may take time and several appointments to confirm a diagnosis. Once confirmed, a care plan will be built around your child's needs, involving specialists, nurses, and your GP.

Treatment

Treatment for childhood lupus focuses on controlling inflammation, managing symptoms, and preventing organ damage. A team of specialists will work with you to create a personalized care plan. The two main types of medicines used are anti-inflammatory medications to reduce swelling and pain, and medicines that calm down the immune system. All treatments are given under the close supervision of a specialist.

Self-care at home

• Protect your child's skin from the sun with sunscreen, hats, and protective clothing.
• Make sure your child gets enough rest, especially during flare-ups.
• Encourage a healthy, balanced diet to support growth and energy.
• Keep up with regular appointments and take all medicines as prescribed.
• Learn what triggers your child's flare-ups and try to avoid them.

Medical treatments

Medical treatment often includes non-steroidal anti-inflammatory drugs (NSAIDs) for pain and swelling, corticosteroids to quickly bring down inflammation, and medicines that adjust or suppress the immune system. The specialist will choose the right combination based on your child's symptoms and test results. Some medicines are given by mouth, while others are given as injections or infusions.

When is surgery considered?

Surgery is not usually needed for lupus itself. However, if the kidneys are severely affected, a small procedure called a kidney biopsy might be performed to help guide treatment. This involves taking a tiny sample of kidney tissue for testing.

Living with this condition

Living with lupus means learning to manage ups and downs. Your child will have good days and bad days. Building a strong support network at school and at home can make a big difference. Teachers should understand that your child may need flexibility during flare-ups.

Lifestyle tips

• Create a calm, stress-free home environment where your child feels supported.
• Help your child stay socially connected with friends and hobbies.
• Encourage gentle exercise like walking or swimming when energy allows.
• Make sure your child wears sun protection every day, even in winter.

Diet and exercise

A balanced diet rich in fruits, vegetables, whole grains, and lean protein helps keep the body strong. Some children may need to avoid certain foods if they affect symptoms. Exercise, when done gently, can reduce joint stiffness and improve mood. Always check with your doctor before starting a new exercise routine.

Mental health and emotional wellbeing

Living with a chronic condition like lupus can be emotionally tough for a child and for parents. Feelings of frustration, anxiety, or sadness are normal. It is important to talk openly about feelings and to seek professional help if needed. If your child ever expresses thoughts of harming themselves, call your local emergency number or a mental health crisis line immediately.

Prevention

Lupus cannot be prevented, because its causes are not fully understood. However, flare-ups can be reduced by following the treatment plan and avoiding known triggers, especially sun exposure and infections.

Vaccines

Keeping your child's routine vaccinations up to date is important because infections can trigger lupus flare-ups. Some vaccines are live, which may not be safe for children taking strong immune-suppressing medicines. Discuss vaccination with your specialist.

Screening programmes

Regular monitoring is needed to check for complications. This may include blood pressure checks, urine tests, and eye or kidney screenings. Sight checks are also recommended if your child takes certain medications over a long period.

Complications

If left untreated

• Kidney damage that could progress to kidney failure
• Damage to the heart, lungs, or nervous system
• Increased risk of serious infections, especially if the immune system is not treated or is over-suppressed
• Bone thinning (osteoporosis) from long-term inflammation or steroid use

Long-term outlook

With early diagnosis and the right treatment, most children with lupus live full and active lives. The condition can change over time, and long-term monitoring is important. There is no cure yet, but research is improving care every year. Your health team is there to help you navigate each stage.
