Can NEC cause brain damage?

Physicians have long known that necrotizing enterocolitis (NEC), a potentially lethal inflammatory condition that destroys a premature infant’s intestinal lining, is often connected to the development of severe brain injury in those infants who survive.

What is NEC disorder?

Necrotizing enterocolitis (NEC) is a serious gastrointestinal problem that mostly affects premature babies. The condition inflames intestinal tissue, causing it to die. A hole (perforation) may form in your baby’s intestine. Bacteria can leak into the abdomen (belly) or bloodstream through the hole.

Can NEC cause seizures?

Neonatal seizures have been associated with adverse neurologic outcomes, including cerebral palsy and post-neonatal epilepsy,3–6 but whether this is a causal relationship is controversial….Table II.

How does NEC happen?

It happens when tissue in the small or large intestine is injured or inflamed. This can lead to death of intestinal tissue and, in some cases, a hole (perforation) in the intestinal wall. In NEC, the intestine can no longer hold waste. So bacteria may pass into the bloodstream and cause a life-threatening infection.

What are the long term effects of NEC?

Common complications of NEC include neurodevelopmental delay, failure to thrive, gastrointestinal problems including strictures and adhesions, cholestasis, short bowel syndrome with or without intestinal failure that can be difficult to manage.

Can NEC cause autism?

It has been proposed that abnormal gut development may contribute to these problems. In turn, delayed gut development may affect the gut-brain axis communication and lead to altered brain development implicated in autism. In the premature infants IBD occurs primarily in the form of necrotizing enterocolitis (NEC).

What are long term effects of necrotizing enterocolitis?

What is the survival rate for NEC?

Summary. Mortality among infants who have NEC remains high, and infants who die of NEC commonly (66%) die quickly. Most of the factors associated with mortality are related to immaturity, low birth weight and severity of illness.

Is NEC genetic?

also demonstrated that more than 50% of variance in NEC is accounted for by genetic and shared environmental factors.

Is the NEC preventable?

Can necrotizing enterocolitis be prevented or avoided? It is hard to prevent or avoid NEC. However, there are factors that can increase your baby’s risk for NEC, including: premature birth.

How fast does NEC progress?

Necrotizing enterocolitis often develops within the first two weeks of life, usually after milk feeding has begun (at first, feedings are usually given through a tube that goes directly to the baby’s stomach).

What is the pathophysiology of necrotizing enterocolitis?

Necrotizing enterocolitis is usually idiopathic and multi-factorial. A combination of ischemic and infective etiology with added contributive factors such as immature immunity have been proposed 1 . Although a partially infective etiology has been hypothesized, no causative organism has been isolated.

Do microbiota play a role in the development of enterocolitis?

Necrotizing enterocolitis (NEC) is a relatively common disease in very-low-birth-weight infants and is associated with high mortality and morbidity. In survivors, neurodevelopmental impairment is frequently seen. The exact etiology remains largely to be elucidated, but microbiota are considered to play a major role in the development of NEC.

What are the treatment options for necrotizing enterocolitis?

Necrotizing enterocolitis can be managed both medically and surgically and appropriate patient selection is essential in optimizing outcome. A clinical staging system has been developed (see necrotizing enterocolitis staging ), with stage I and II receiving medical therapy and stage III undergoing surgery 8.

What is the pathophysiology of necrotic necrosis of the ileum?

Inflammation starts from the mucosal surface and progresses to hemorrhagic and coagulative necrosis. There is ensuing loss of mucosal integrity, transmural necrosis, and perforation. Although NEC can affect any part of the large or small bowel, the most common location is the terminal ileum.
