Living with Alport syndrome awareness

Overview

Alport syndrome is a genetic condition that mostly affects the kidneys, ears, and eyes. It causes the tiny blood vessels in these parts of the body to become weak and leaky. Over time, this can lead to kidney damage, hearing loss, and vision problems. It is caused by changes in certain genes that help build a type of protein called collagen, which supports the structure of your body's tissues.

No, Alport syndrome is rare. It is thought to affect about 1 in every 5,000 to 10,000 people worldwide. Many people with the condition go undiagnosed, so the true number may be higher.

Alport syndrome can affect anyone, but it is most often passed down through families. Men and those assigned male at birth usually have more severe symptoms and may develop kidney failure earlier in life. Women and those assigned female at birth can also be affected, but their symptoms are often milder and may appear later. It can affect people of all ethnic backgrounds.

Symptoms

Common symptoms

• Blood in the urine (hematuria), which often starts in early childhood.
• Protein in the urine (proteinuria), which may be discovered during a urine test.
• High blood pressure.
• Hearing loss that begins in the teenage years, especially for boys.
• Eye changes, such as problems with the lens of the eye or a speckled appearance on the retina, usually seen during an eye exam.

Symptoms in children

• Blood in the urine, often noticed during routine checkups or after an illness.
• Sometimes a child may have no other symptoms while the disease slowly progresses.
• Children may also have a mild hearing problem that only shows up on a special test.
• Some children with Alport syndrome may develop kidney problems in their late teens or early adulthood.

Symptoms in older adults

• Worsening kidney function, which can lead to tiredness, swelling in the legs, and increased need to urinate at night.
• More noticeable hearing loss that can interfere with daily communication.
• Vision changes, including weakening of the clear front part of the eye (cornea) or a clouding of the lens (cataract).
• High blood pressure that becomes harder to control.

Causes

Main causes

• Changes (mutations) in the COL4A3, COL4A4, or COL4A5 genes.
• These genes contain the instructions for making collagen type IV, which helps build the basement membrane in parts of the kidney, ear, and eye.
• When the collagen is faulty, the basement membrane becomes damaged and loses its ability to filter waste properly, leading to kidney damage, hearing loss, and eye problems.

Risk factors

• Having a parent with Alport syndrome or carrying a disease-causing gene change.
• Being born with an X-linked form of Alport syndrome (a pattern where the mutated gene is on the X chromosome).
• Having a family history of chronic kidney disease, hearing loss, or vision problems of unknown cause.

When to see a doctor

See a doctor urgently if:

• If you see blood in your or your child's urine, especially if it is accompanied by pain, fever, or trouble urinating.
• If you notice sudden swelling in your face, hands, or legs.
• If you have a severe headache that does not improve with your usual pain relief and you also have a family history of kidney or hearing disease.

Book a routine appointment if:

• If you have a family history of Alport syndrome, even if you have no symptoms.
• If your child has repeated episodes of blood in the urine or abnormal urine tests.
• If you have been diagnosed with high blood pressure or unexplained kidney problems.
• If you or your child have hearing loss that seems out of place for the age (for example, hearing loss before age 30) and there is also a family history of kidney disease.

Diagnosis

A doctor, usually a kidney specialist (urologist or nephrologist), can diagnose Alport syndrome by looking at your medical history, urine tests, hearing tests, eye exams, and genetic testing. In some cases, a kidney biopsy (a small sample of kidney tissue) may be needed to confirm the diagnosis or to see the damage level.

Tests that may be done

• Urine tests to check for blood and protein.
• Blood tests to measure how well your kidneys are working (creatinine and estimated glomerular filtration rate).
• Hearing tests (audiogram) to check for sensorineural hearing loss.
• Eye exam by an ophthalmologist (eye specialist) to look for lens problems or retinal changes.
• Genetic testing to look for mutations in the COL4A3, COL4A4, or COL4A5 genes.
• Kidney biopsy, which is not needed for everyone but can help confirm the type and severity.

What to expect at your appointment

When your doctor suspects Alport syndrome, you will likely see a specialist team. They will talk through your family history, the pattern of your symptoms, and arrange the necessary tests. Results come back at different times: urine and blood tests are usually quick, genetic testing may take a few weeks, and a kidney biopsy is done as a planned hospital procedure. The team will explain what every test finds and will help you understand what living with Alport syndrome means for you.

Treatment

There is currently no available treatment that can reverse Alport syndrome, but there are very effective ways to slow down kidney damage, protect your hearing, and manage any eye problems. The main goal is to keep your blood pressure low and protect your kidneys from extra stress. With regular checkups and a good care plan, many people with Alport syndrome live full, active lives.

Self-care at home

• Drink enough water throughout the day to stay well hydrated, but not in excessive amounts. Talk to your doctor about the right amount for you.
• Avoid medicines that can harm the kidneys, such as non-steroidal anti-inflammatory drugs (NSAIDs), including ibuprofen and naproxen. Always check with your doctor or pharmacist first.
• Control high blood pressure by following your doctor's advice on diet, exercise, and medications.
• Protect your ears by avoiding loud noises and using ear protection in noisy environments. If you have hearing loss, consider using hearing aids when they are recommended.
• Have an eye checkup every year or two, and report any changes in vision to your doctor.

Medical treatments

Doctors may prescribe medicines that help lower blood pressure and reduce the amount of protein leaking into the urine. These medicines are often called ACE inhibitors or ARBs. They are important not only for blood pressure but also for protecting kidney function over time. For more advanced kidney disease, medications may be needed to treat the buildup of waste products in the blood, manage anemia, or control calcium and phosphate levels. All medicine choices are made by your healthcare team, and they will explain the benefits and possible side effects. The exact type and dose are individual to you.

When is surgery considered?

When someone with Alport syndrome reaches end-stage kidney disease (the kidneys stop working well enough to keep you alive), a kidney transplant is the best treatment option. In that case, surgery is needed to replace the failed kidney with a healthy one from a donor. Many people who receive a kidney transplant go on to live many more active years. During the transplant evaluation, your team will perform many tests and talk to you about the risks and benefits.

Living with this condition

Living with Alport syndrome means learning to listen to your body and staying in partnership with your healthcare team. You will likely have regular appointments to check your blood pressure, urine, and kidney function. Keep a symptom diary, and tell your doctor about any new changes, such as fatigue, swelling, or hearing loss. It is also helpful to know your family history and to communicate with relatives about the importance of being checked.

Lifestyle tips

• Stay physically active with moderate exercises like walking, swimming, or cycling to keep your blood pressure healthy.
• Follow a balanced diet that is not too high in salt, as salt can raise blood pressure and increase urine protein.
• Avoid smoking and limit alcohol, because both can raise blood pressure and make kidney problems worse.
• Manage stress with relaxation techniques, talking to a friend, or joining a support group.

Diet and exercise

There is no special 'Alport diet', but kidney-friendly habits are important. That means eating plenty of fruits and vegetables, whole grains, and lean proteins, while limiting processed foods that are high in salt. When kidney function declines, your doctor or a dietitian may suggest adjusting the amount of potassium, phosphorus, or protein in your diet. Regular exercise, like brisk walking for 30 minutes most days, is beneficial. If you have hearing or balance problems, a physiotherapist can help you adapt your activities safely.

Mental health and emotional wellbeing

Being told you or your child has a long-term genetic condition can bring up many emotions, including worry, sadness, or guilt. It is natural to feel this. Remember that your feelings are important, and seeking emotional support is a sign of strength. If you feel anxious or depressed, speak to your healthcare team or a mental health professional. For parents of a child with Alport syndrome, talking to a child psychologist can help the whole family adjust. You are not alone in this, and support is available.

Prevention

Because Alport syndrome is caused by changes in your genes, it cannot be prevented. However, the progression of kidney damage can often be slowed or delayed. Early diagnosis and careful regular monitoring are the best ways to protect your kidneys for as long as possible. Genetic counseling can help you understand your family's risk and, if you plan to have children, the chances of passing on the gene.

Vaccines

Everyone with Alport syndrome, and especially those with kidney disease, should stay up to date with routine vaccinations, including the annual flu jab and the COVID-19 vaccine. Some vaccines (like the chickenpox vaccine or live vaccines) may need special timing if you are taking immunosuppressant medicines after a transplant. Ask your healthcare team about the right vaccine schedule for you.

Screening programmes

For people with a family history of Alport syndrome, regular screening is important. This includes urine tests for blood and protein, blood pressure checks, hearing tests, and eye exams. For children, screening may begin in infancy if there is a known family history. Genetic testing can also help identify at-risk family members even before symptoms appear.

Complications

If left untreated

• Chronic kidney disease that gradually worsens and can lead to needing dialysis (a treatment that filters wastes from the blood).
• Hearing loss that becomes severe enough to affect speech and communication.
• Vision problems that can affect reading, driving, and quality of life.
• High blood pressure that can damage the kidneys further and increase the risk of heart disease.

Long-term outlook

Although Alport syndrome is a serious condition, many people live well into middle age and beyond, especially when they are diagnosed early and follow a good care plan. New treatments are being studied, and kidney transplantation is very successful for those who need it. With advice about blood pressure control, hearing aids, eye care, and a healthy lifestyle, you can keep living a full and active life. Research into gene-based therapies offers hope for the future.
