Jaundice is a common condition that affects many infants in the early days of life. It occurs when there is a buildup of bilirubin in the baby’s blood, leading to a yellowish discoloration of the skin and the whites of the eyes. While mild jaundice often resolves on its own, in some cases, it can be a sign of an underlying health issue that requires prompt attention and appropriate treatment. Understanding the causes, symptoms, and available treatment options is crucial for ensuring the well-being of newborns and providing peace of mind to parents. In this article, we will explore how to cure jaundice in infants.
What is Bilirubin and Why Does it Build Up in Infants?
Bilirubin is a yellow pigment that is produced when red blood cells break down. In adults, the liver efficiently processes bilirubin and excretes it into the bile, which then passes out of the body through the intestines. However, in newborns, the liver is still maturing and may not be fully capable of handling the normal breakdown of red blood cells that occurs after birth. Additionally, infants have a higher turnover rate of red blood cells in the first few days of life, leading to an increased production of bilirubin.
There are two main types of bilirubin: direct (conjugated) and indirect (unconjugated). Indirect bilirubin is the form that is initially produced from the breakdown of red blood cells and needs to be processed by the liver to become direct bilirubin, which can be excreted. Problems in the liver’s ability to conjugate (process) the bilirubin or in the elimination of the conjugated bilirubin can result in its accumulation in the bloodstream and, subsequently, the appearance of jaundice.
Types of Infant Jaundice
1. Physiological Jaundice
This is the most common type and usually appears 2 to 3 days after birth. It is a normal part of the transition from the womb environment to the outside world. The mild elevation of bilirubin levels is due to the factors mentioned earlier, such as the immature liver function and increased red blood cell breakdown. In most cases of physiological jaundice, the bilirubin levels peak around the 4th or 5th day of life and then gradually decline, resolving completely within 1 to 2 weeks without any specific treatment required. The yellowish tint of the skin and eyes is typically mild and may not cause any other symptoms in the baby.
2. Breastfeeding Jaundice
Some breastfed infants develop jaundice that persists longer or is more pronounced than physiological jaundice. This can be related to insufficient milk intake in the early days. When a baby is not getting enough breast milk, they may have fewer bowel movements, which means less bilirubin is being excreted through the feces. As a result, bilirubin is reabsorbed back into the bloodstream, leading to higher levels and more visible jaundice. Another possible factor is substances in breast milk that may affect the liver’s processing of bilirubin, although the exact mechanisms are still being studied.
3. Breast Milk Jaundice
This is a separate condition that occurs in a small percentage of breastfed babies. It typically appears after the first week of life, often around day 7 to 10, and can last for several weeks. The cause is thought to be related to specific components in breast milk that interfere with the normal metabolism and excretion of bilirubin. Unlike breastfeeding jaundice related to poor intake, breast milk jaundice may occur even when the baby is feeding well and gaining weight appropriately.
4. Pathological Jaundice
Pathological jaundice is less common but more concerning as it is often associated with an underlying medical problem. It can present at birth or within the first 24 hours of life, which is earlier than physiological jaundice. Causes include blood group incompatibility (such as Rh or ABO incompatibility), infections (either in the mother during pregnancy that are passed on to the baby or infections acquired during birth), congenital liver disorders, and other genetic or metabolic conditions that affect the liver’s ability to process bilirubin. Babies with pathological jaundice may have other symptoms along with the yellowish discoloration, such as lethargy, poor feeding, vomiting, or an enlarged liver or spleen.
5. Diagnosis of Infant Jaundice
The diagnosis of jaundice in infants begins with a visual inspection by healthcare providers. They look for the characteristic yellowish tint of the skin, starting from the face and progressing down the body, as well as the yellowing of the sclera (whites) of the eyes. However, visual assessment alone is not sufficient.
To accurately measure the bilirubin levels, a blood test called a total serum bilirubin test is usually performed. This test provides a quantitative measurement of the amount of bilirubin in the blood. In some hospitals and clinics, transcutaneous bilirubinometry may also be used. This is a non-invasive method where a special device is placed on the baby’s skin to estimate the bilirubin levels. It is often used for screening purposes and can be repeated easily, but if the levels seem elevated, a confirmatory blood test is still required.
In cases where pathological jaundice is suspected, additional tests may be ordered. For example, if blood group incompatibility is a concern, blood typing and antibody screening of both the mother and the baby are done. Tests for infections, such as a complete blood count to look for signs of infection, cultures of blood, urine, or cerebrospinal fluid if appropriate, and specific genetic or metabolic tests if a congenital disorder is suspected, may also be carried out.
Treatment Options for Infant Jaundice
1. Phototherapy
Phototherapy is the most common treatment for jaundice in infants, especially for those with moderate to high bilirubin levels. It works on the principle that exposure to specific wavelengths of light (usually blue or green light) helps to break down the bilirubin molecules in the skin. The baby is placed under special phototherapy lights, either in an incubator or on a warming bed with the lights positioned above. The baby is usually undressed except for a diaper to maximize skin exposure to the light. During phototherapy, the baby’s eyes are covered with protective shields to prevent damage to the retina from the light. The duration of phototherapy depends on the initial bilirubin level and how quickly it decreases during treatment. In some cases, it may be required for just a few hours a day for a couple of days, while in more severe cases, continuous phototherapy for 24 hours may be necessary for several days. Regular blood tests are done to monitor the bilirubin levels and adjust the treatment as needed. Parents are often allowed to stay with the baby during phototherapy to provide comfort and feed the baby as usual, although they need to be careful not to block the light from reaching the baby’s skin.
2. Exchange Transfusion
Exchange transfusion is a more invasive and serious treatment option reserved for cases where the bilirubin levels are extremely high and there is a risk of developing kernicterus, a condition where the high bilirubin levels cross the blood-brain barrier and can cause brain damage. In an exchange transfusion, a small amount of the baby’s blood is removed and replaced with donor blood that has a lower bilirubin level. This procedure is done under strict medical supervision in a neonatal intensive care unit as it carries risks such as infection, bleeding, and fluid and electrolyte imbalances. However, it can be life-saving in severe cases of jaundice where other treatments have not been effective in rapidly reducing the bilirubin levels.
3. Feeding Management for Breastfeeding-related Jaundice
For breastfeeding jaundice caused by insufficient milk intake, the key is to ensure that the baby is getting enough breast milk. This may involve more frequent breastfeeding, ensuring a proper latch to maximize milk transfer, and in some cases, supplementation with expressed breast milk or formula if the mother’s milk supply is still establishing. Encouraging more frequent bowel movements by gentle tummy massages can also help in excreting bilirubin. As the baby starts getting an adequate amount of milk and having regular bowel movements, the bilirubin levels often start to decline.
For breast milk jaundice, where the baby is feeding well but still has elevated bilirubin, in most cases, continued breastfeeding is recommended as the benefits of breast milk far outweigh the risks of mild to moderate jaundice. However, in very severe cases where the bilirubin levels are concerning, temporary interruption of breastfeeding for 12 to 24 hours and substituting with formula may be considered, followed by a slow reintroduction of breast milk once the bilirubin levels start to come down. During the interruption, the mother should continue to express milk to maintain her milk supply.
4. Treatment of Underlying Causes in Pathological Jaundice
When jaundice is due to an underlying pathological condition, treating the root cause is essential. For example, in cases of blood group incompatibility, treatment may involve administering medications such as intravenous immunoglobulin to prevent the mother’s antibodies from attacking the baby’s red blood cells further. Infections are treated with appropriate antibiotics or antiviral medications depending on the causative agent. For congenital liver disorders or metabolic conditions, a multidisciplinary approach involving pediatric gastroenterologists, geneticists, and other specialists is often required to manage the condition long-term, which may include dietary modifications, medications to support liver function, and regular monitoring of liver enzymes and bilirubin levels.
Home Care and Parental Support
Parents play a crucial role in the care of an infant with jaundice, even when the baby is receiving medical treatment in the hospital. At home, they should closely monitor the baby’s skin color, especially the yellowish tint, and report any changes or concerns to the healthcare provider promptly. They should also ensure that the baby is feeding well, whether breastfed or formula-fed, and keep track of the number of wet and soiled diapers as this indicates proper hydration and elimination of bilirubin.
During phototherapy at home, if prescribed, parents need to follow the instructions carefully regarding the setup of the home phototherapy unit, positioning of the baby, and protection of the eyes. They should also be vigilant about any signs of skin irritation or overheating of the baby during treatment. Providing a calm and comfortable environment for the baby, with plenty of cuddles and interaction when possible, helps in reducing the baby’s stress and promoting overall well-being.
In conclusion, infant jaundice is a complex but manageable condition. Understanding the different types, causes, diagnosis methods, and treatment options empowers parents and healthcare providers to take appropriate action to ensure the healthy development of newborns. With timely intervention and proper care, most infants with jaundice recover fully, growing up to be healthy children without any long-term consequences related to the early jaundice episode. Regular check-ups and communication with the pediatrician are vital throughout the process to monitor the baby’s progress and address any emerging issues promptly.
