Neonatal Jaundice: An Evolutionary Safeguard


In infants, jaundice emerges from develop of bilirubin, a yellow pigment, in the bloodstream. Bilirubin is a normal by product of the breakdown of red blood cells, but at very high levels, the compound is toxic to brain cells and can cause permanent damage. It affects around 75% of term babies and around 85% of preterm babies in the first week of their lives. According to new research, it is stated that, Jaundice is one of the gifts of evolution. Humans may develop jaundice as new born to protect from something even more serious: sepsis.

Risk factors:
Premature birth: Premature babies also may feed less and have fewer bowel movements, resulting in less bilirubin eliminated through stool.
Blood type: If the mother's blood type is unique in relation to her baby's, the infant may have gotten antibodies through the placenta that reason unusually fast breakdown of red platelets.
Breast-feeding:  Breast-fed babies, particularly those who have difficulty nursing or getting enough nutrition from breast-feeding are at higher danger of jaundice. Lack of hydration or a low caloric admission may add to the beginning of jaundice.
Since it can lead to conditions like acute bilirubin encephalopathy and kernicterus, hat can harm the new-born child's mind and cause developmental issues.
             Richard, one of the renowned scientist, start his search on this and started thinking about the problem in evolutionary terms. The team found that bilirubin seemed to impact the growth of the bacteria (Gram-positive Streptococcus agalactiae) which are most commonly causes early sepsis in infants. With other bacteria implicated in sepsis, the outcomes mixed: bilirubin also affected some types of Staphylococci, but not Gram-negative Escherichia coli.
Treatment
The best preventive of new-born child jaundice is sufficient sustaining. Breast-fed infants should have 8 to 12 feedings a day for the first several days of life. Photo therapy likewise works by bringing down bilirubin levels.
