Rare Flu Complication Leaves Toddler in Critical Condition

A two-year-old girl, previously healthy and without pre-existing conditions, is in critical condition in the Pediatric Intensive Care Unit at Shaare Zedek Medical Center in Jerusalem due to a rare complication of influenza. The child, who had received routine vaccinations but not the seasonal flu shot, was rushed to the hospital after experiencing seizures at home. She had been suffering from fever and vomiting for 24 hours, and due to a lack of appetite, had been drinking large amounts of water.

Doctors diagnosed the girl with SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion), a condition where the body produces too much ADH, causing the kidneys to retain excessive water. This leads to a dangerous drop in blood sodium levels, known as hyponatremia, which can cause seizures and be life-threatening if untreated. Dr. Giora Weizman, director of the pediatric ICU, explained that in such cases, limiting fluid intake is crucial to reduce water overload, after ruling out other causes like dehydration.

While the child's condition is now stable and improving, Dr. Amir Zilka, a senior physician in the unit, noted that while SIADH is a known flu complication, its severity in this case is rare. He emphasized the importance of routine vaccinations and the seasonal flu shot as the best protection against potentially severe and life-threatening influenza.

Shaare Zedek Medical Center is currently treating 10 flu patients, three of whom are in intensive care, the highest number this season. This case follows other severe flu-related hospitalizations across the country, including an 8-year-old girl in critical condition at the same hospital the previous week, also unvaccinated against the flu. In a separate case, a 17-year-old girl who was hospitalized in serious condition with the flu at Assuta Ashdod has recovered and is no longer in life-threatening danger.
