Youths and children top Mumbai's dengue casualties

MUMBAI: The aedes mosquito seems to have caused more damage to youngsters this season. Out of the nine Mumbaikars who succumbed to dengue this year-confirmed or otherwise- five were minors, while three were in their early 20s.
In some cases dengue appeared to go the swine flu way, as significantly higher number of patients from vulnerable groups like children, pregnant women and people with underlying problems landed up in intensive care units.
Experts say that though there is no study to prove it yet, it might be possible that the immunity system of the young itself may be playing the foe. Doctors admitted the incidence of dengue deaths is much more than what is being reported in civic hospitals.
Dr Khusrav Bajan, intensivist at Hinduja Hospital, said the systemic inflammatory response syndrome (SIRS) is higher among youngsters. "Whenever there is an infection that affects the body, the immunity system gives a very strong response. It releases cytokine mediators, a type of toxins to kill the infection," he said. However, this syndrome may backfire and inflame the normal cells too. "This response is much higher in a teenager's or a youngster's body. Since they release more toxins, it may just lead to multi-organ failure," Dr Bajan said.
The BMC meanwhile, has not yet made the same conclusions. "There have been 660 cases of dengue reported in civic hospitals this year so far. There have been six confirmed deaths, two suspected deaths due to dengue and we are still awaiting post-mortem report of another one to know if it is a death due to dengue," said Dr Mangala Gomare. "We have not yet studied all the cases, but a few of the deaths seem to have occurred because of dengue shock syndrome," she said.
Dr Om Srivastava, director of infectious diseases department at Jaslok Hospital, said the pattern of dengue presentations have changed. "It is not just the platelets that decrease. White blood cells start to fall and the platelets drop only by the fourth or fifth day now. Also, the time between getting the virus and becoming acutely ill has decreased, leading many patients to the ICU," he said.
