ADPKD is the most frequent type of polycystic kidney disease. ADPKD affects approximately between a quarter to a tenth of all individuals, and is the inheritance of the most prevalent kidney ailment between relatives. Health care providers typically identify ADPKD between the ages of 30 and 50, when manifestations begin to become evident, hence why adults are commonly referred to as having “adult PKD.”
The phrase “autosomal dominant” implies that an individual only requires the PKD gene defect from one of their parents in order to manifest the condition. Scientists have discovered two distinct gene alterations that are the source of Autosomal Dominant Polycystic Kidney Disease. Approximately one-sixth to one-seventh of individuals diagnosed with ADPKD have a flawed PKD2 gene, with most people with this condition suffering from PKD1 gene abnormalities.
Medical personnel are now able to recognize patients with PKD1 earlier because the associated symptoms manifest earlier. Those who suffer from PKD1 typically experience a faster decline in kidney function that leads to failure in comparison to those who are afflicted with PKD2. The speed at which ADPKD advances varies from individual to individual.
What are the most common complications of ADPKD?
Most individuals having ADPKD endure some degree of discomfort, hypertension, and renal deterioration at some point in their lifetime.
Pain
ADPKD often produces ache, which generally originates from cysts on the kidney or liver. Pain also can be caused by
- kidney cyst infection
- bleeding or burst kidney cysts
- urinary tract infection
- kidney stones
- tissue stretching around the kidney due to cyst growth
High blood pressure
Almost everyone suffering from ADPKD who is experiencing kidney issues also has elevated blood pressure. The likelihood of developing heart disease and stroke increases with elevated blood pressure. Your kidneys can be further harmed by elevated blood pressure. Maintain your blood pressure at a regulated level in order to slow down kidney deterioration.
Many individuals with Autosomal Dominant Polycystic Kidney Disease experience ache, elevated blood pressure, and renal failure at some point during their lifespan.
Kidney failure
Renal insufficiency indicates that your kidneys are no longer operating at a level sufficient enough to maintain your health. Untreated kidney failure can lead to coma and death. Approximately greater than fifty percent of individuals with Autosomal Dominant Polycystic Kidney Disease develop kidney deficiency by the age of 70.
What are other complications of ADPKD?
Complications from Autosomal Dominant Polycystic Kidney Disease (ADPKD) can have an effect on several organs in your body, not solely your kidneys. Investigations have not revealed any connection between PKD and renal carcinoma.
You may see some ADPKD complications right away. It may take long periods of time for any issues to develop from having either the PKD1 or PKD2 gene. The seriousness of the problems associated with ADPKD can differ from individual to individual, meaning not everyone will experience the same issues.
Vascular system problems
Abnormal heart valves. Some individuals with ADPKD may have irregular heart valves. Abnormal heart valves can lead to an insufficient amount of blood being carried from the heart to the aorta, the key artery responsible for distributing blood throughout your body. People with ADPKD typically will not require a new heart valve as a result of any irregularities. You may require further testing if your doctor finds any evidence of a heart murmur.
Brain aneurysms. A blood vessel’s wall may bulge out, forming an aneurysm. Brain aneurysms may give rise to headaches that are intense or not similar to other headaches. Consult a medical professional prior to taking any over-the-counter pain medication for persistent or serious headaches.
A brain aneurysm can rupture and result in the intracranial bleeding. Major brain aneurysms are care threatening and need urgent medical attention. If you have an aneurysm, quitting smoking and regulating your blood pressure and cholesterol levels is essential.
Digestive system problems
Liver cysts. The most common abnormality that occurs to the liver and is not connected to the kidneys in autosomal dominant polycystic kidney disease (ADPKD) is an accumulation of water-filled sacs in and around the organ. Young individuals often don’t have problems related to liver cysts since they generally don’t have many and they are usually tiny in the early stages of Autosomal Dominant Polycystic Kidney Disease. In exceptional instances, liver cysts can diminish the performance of the liver over time. In the most grave instances, a liver transplant could be required.
Females are more likely to have liver cysts than males due to estrogen, a hormone, possibly influencing their development. Increasing the number of pregnancies a woman with ADPKD has had multiplies the chances that she will develop liver cysts.
Pancreatic cysts. PKD can also cause cysts in your pancreas . Pancreatic cysts are not usually the cause of pancreatitis, a condition wherein the pancreas becomes swollen and inflamed.
Diverticula. Diverticula are tiny pockets that protrude from the wall of the colon where the tissue is frail. Diverticula can cause diverticulosis. Diverticulosis can lead to alterations in your intestinal transit rituals or pain in your stomach.
Urinary tract problems
Urinary tract infections (UTIs). Kidney cysts can keep urine from draining away from the kidneys in a timely manner, resulting in it lingering in the urinary tract. If urine is allowed to linger in the urinary tract beyond its normal timeframe, bacteria that resides in the urine can lead to a bladder or kidney infection. An infection of the kidneys can cause cysts to become contaminated, thereby leading to more harm to them.
Kidney stones. People with ADPKD sometimes have kidney stones . Kidney stones can obstruct urine output and result in infection and discomfort.
Reproductive problems
Although the majority of female PKD sufferers have a regular gestational stage, those with hypertension and renal impairment are more vulnerable to experiencing preeclampsia or elevated hypertension while pregnant.
With preeclampsia, the unborn baby does not receive adequate oxygen and essential nutrients. Expectant mothers who suffer from preeclampsia should be kept under close supervision by their medical specialist both during and after their pregnancy. After delivery, preeclampsia goes away.
A lot of guys having ADPKD have sacs on their seminal vesicles, which are components in the male reproductive system that assist in creating sperm. Seminal vesicle cysts rarely cause infertility.
People who have Polycystic Kidney Disease and are thinking of starting a family may want to talk to a genetic counselor about any potential family planning matters.
What are the signs and symptoms of ADPKD?
In many instances, symptoms of ADPKD are not observed until the cysts become bigger than 1.27 cm (or half an inch) in diameter. It is wise to connect with a medical specialist if you are in danger of developing PKD before you begin displaying signs.
The most prevalent indications are discomfort in the back and around the ribs and hips area, as well as migraine. The suffering may be fleeting or 24/7, simple or intense.
Urine containing blood may be an indication of Autosomal Dominant Polycystic Kidney Disease (ADPKD). You should immediately consult a health care provider if you experience hematuria.
BONUS: ADPKD and pregnancy
Before you become pregnant
Can women with ADPKD get pregnant?
One’s renal capability has a big bearing on their capacity to conceive and have a successful pregnancy. If your kidneys are functioning properly, there should be no change to your fertility compared to before you had Autosomal Dominant Polycystic Kidney Disease (ADPKD). If your kidney is not functioning properly, the concentrations of reproductive hormones in your system can be significantly decreased, making it more difficult to become pregnant.
About one-fifth of ladies in the general populace encounter a premature delivery before 12 weeks of pregnancy. One research paper has indicated that expecting mothers diagnosed with ADPKD and who are receiving treatment to control high blood pressure may encounter a slightly greater risk of miscarriage, rising to 30% out of 10 pregnancies.
If you are having trouble getting pregnant, ask your general practitioner or nephrologist to refer you to a reproductive specialist.
Can men with ADPKD father children?
Generally speaking, males with autosomal dominant polycystic kidney disease (ADPKD) have normal fertility, except in cases where their kidney function is decreased. Individuals with severe Autosomal Dominant Polycystic Kidney Disease (ADPKD) who have gone through a transplant procedure generally become fertile shortly after the procedure. It is rare for Autosomal Dominant Polycystic Kidney Disease to have an effect on one’s fertility, though it may lead to cysts in the reproductive system. If you are looking for guidance concerning your fertility, consult with your general practitioner or nephrologist.
What is the risk of my baby inheriting ADPKD?
If you and your companion possess Autosomal Dominant Polycystic Kidney Disease, then there is a 50% chance that your newborn will inherit a defective gene and develop ADPKD at some point during their life. You can learn more about the manner in which ADPKD is passed down genetically by consulting our informational document, ‘Genetic Counselling and Genetic Testing in ADPKD’.
Speak with your doctor about the prospect of your infant having ADPKD and inquire them to direct you to a genetics consultant. It would be beneficial to investigate whether there is the potential for using specialist IVF to choose an embryo which does not possess ADPKD (as mentioned in the IVF section).
Does ADPKD affect a pregnancy?
The majority of females with Autosomal Dominant Polycystic Kidney Disease have uneventful pregnancies and vigorous infants. If your kidneys are working correctly or just slightly impaired, you stand a high chance of having a successful pregnancy. As kidney function deteriorates, the potential for issues during pregnancy rises, yet this does not hold true for all people.
A medical professional who is an expert in kidney conditions (a nephrologist) or pregnancy (an obstetrician) can give you guidance about the possible dangers of pregnancy considering your renal capacity.
A recent study of pregnant women with impaired kidney function who had reached 20 weeks’ gestation revealed that nearly all of them (98%) were able to give birth to a healthy baby. Female recipients of a kidney transplant were just as likely to achieve a successful pregnancy.
If your kidney function is reduced, you’ll have a greater chance of these complications during pregnancy:
- pre-eclampsia: a condition that can be dangerous for both mother and baby
- the fetus growing more slowly than usual or being born a low weight
- your baby being born early – about 7 in every 10 women with moderate or severe kidney disease have a pre-term birth (before 37 weeks)
- your baby needing care in a special unit (a neonatal unit) after birth
- a higher chance of needing a caesarean delivery (operation to deliver the baby).
- Pre-implantation genetic diagnosis (PGD)
There is a greater likelihood of delivering a baby prematurely if one has hypertension before getting pregnant, particularly if it has been an ongoing issue.
During pregnancies, female individuals with kidney disease are carefully watched in order to notice any issues and address them speedily. In this fact sheet, we will explain the additional attention you will receive later.
During pregnancy
Telling your GP and kidney doctor that you are pregnant
Inform your general practitioner when you are expecting a baby so that they can refer you to the right maternity services. Alternatively, you can contact a midwife directly. If possible, inform your kidney doctor straight away too.
Speak with your physician or nephrologist quickly if you are using any of the drugs outlined previously. With the guidance of their physicians, it is safe for you to discontinue the usage of those medications and switch to a different one.
Care during pregnancy
At your initial prenatal hospital visit, you are likely to meet with a midwife, which is ordinary for pregnant women. On this trip, your personal information and past medical history will be documented. You will probably be monitored by an expertise group that consists of an obstetrician dealing with pregnancy and midwives who are well-versed in caring for women with medical issues.
As your gestation progresses, you may be expected to go to the hospital more often than usual for antenatal care, so as to more carefully keep track of you and your baby.
You will have access to the same kinds of ultrasounds scans and blood tests as are available to all women in the United Kingdom. If you have worries regarding the growth of your baby or your blood pressure, you may be offered extra examinations later on in the pregnancy to monitor your baby’s progress.
The birth
Planning the birth
Your choice of location for childbirth will be backed. It is commonly advised by healthcare professionals that you give birth to your baby in a hospital setting. This is caused by your Autosomal Dominant Polycystic Kidney Disease and there is a probability of high blood pressure or pre-eclampsia taking place while delivering or afterwards.
Your care provider may suggest that you have your baby’s heart monitored during labor, likely with either continuous fetal monitoring or cardiotocography (CTG). This signifies that medical personnel will have the ability to monitor the heartbeat of your child throughout your childbirth. It is recommended for females with any type of kidney damage or hypertension to be monitored due to a small likelihood that the placenta might not operate as efficiently as it should. Continuous oversight ensures any modifications to an infant’s heartbeat during labor are discovered and can be watched over carefully and addressed by the midwives and physicians.
MIDWIVES will be responsible for taking care of you during childbirth if your renal performance and blood pressure have been good throughout your pregnancy. Your midwife will stay vigilant in monitoring your blood pressure and carefully listening to your baby’s heart rate. If you experienced difficulties during the pregnancy, it may be suggested that you give birth in a hospital with experts that can closely supervise you and the baby.
It is not a requirement that someone with ADPKD will require a caesarean delivery. Your physicians may suggest that your infant should be born a bit prior to the due date (frequently 1 to 2 weeks early). They will go over the most suitable way of delivery with you.
