These five patients were treated at a New Jersey hospital and serve as a warning that bacterial eroding infections are now occurring outside of traditional geographic boundaries, the authors said.
"It is important that physicians – who may have never seen this infection before in their medical practice – be made aware," co-authored Dr. Katherine Doktor, infectious disease specialist at Cooper University Health Care. , in an email. .
Although Vibrio is endemic off the coast of Virginia and Maryland in Chesapeake Bay, as well as in the southern waters of the United States, these diseases rarely occur in the cooler Delaware Bay, whose waters splash south of New Jersey.
"Although infection is still rare, it is seen more frequently in this region," said Doktor.
The five patients who received treatment at Cooper University Hospital, New Jersey, illustrate this changing reality:
A 38-year-old man arrived at the hospital vomiting, with a fever and rash on his soft left calf. His blood cultures confirmed Vibrio, already evident by his dying skin. Although he was not near Delaware Bay, he was working in a New Jersey restaurant that probably served seafood from the bay. A successful treatment, which included skin grafts, led to his discharge from the hospital.
The second patient, a 64-year-old man, sought medical attention two days after cleaning and eating Delaware Bay crabs. His right hand had begun to swell. After checking Vibrio, his doctors removed portions of deep connective tissue. At a third attempt to eliminate all the dead and dying skin, the patient's heartbeat became irregular and he died.
A third man, aged 46, appeared at the Cooper University Hospital to complain of a swollen left leg two days after being crab injured in Delaware Bay. Skin and blood cultures confirmed Vibrio infection. Vesicles on his calf caused the doctors to remove the connective tissue and perform transplants.
Arrived at the hospital with a severely swollen right leg, a 60-year-old man suffered shock followed by respiratory failure. He had cracked in Delaware Bay and prepared a dozen crabs. Excessive coagulation blocked his small blood vessels and his four limbs became "mummified" and therefore required amputation, wrote the study's authors. His late arrival at the hospital caused the severity of his Vibrio infection.
The last patient, a 64-year-old man, had cut his right leg to a Delaware Bay crab trap before appearing at Cooper University Hospital. Haemorrhagic lesions on his right arm caused a shock. The hospital confirmed Vibrio and removed the tissue dying.
"In all the cases we saw, patients had known risk factors (liver disease, diabetes or other immune deficiency) when a skin lesion was exposed to water and / or [when the patient] eat uncooked molluscs and shellfish harvested from Delaware Bay, "wrote Doktor.
Who is at risk for Vibrio
"It's suggestive, is not it?" Spann asked, who was not involved in the research. He added that it is "hard to say that all of this is due to climate change – although it could very well be".
However, people need to know that "this is a problem," said Spann. "You hear about cases, but it's not like an epidemic." This is true even in areas surrounding much warmer Texan waters, where flesh-eating bacterial infections are more common but not "super common".
Having a wound exposed to the brackish water where these bacteria live is a means of contracting an infection; eating contaminated molluscs – "oysters, mainly" – is another, he said. "Certainly, people in this area would benefit from paying attention to that."
One way to stay safe is to cook the mollusks well before eating them, said Spann.
Doktor nodded, adding, "Anyone with cuts, wounds, broken skin or immunocompromised diseases who notice changes or infection after spending time in the water (especially brackish water) should seek immediate medical attention. (early medical intervention) the best results. "
