Overview
Coxsackie B is the name of a group of six serotypes of pathogenic enteroviruses that trigger illness ranging from mild gastrointestinal distress to full-fledged pericarditis, myocarditis, pericardial effusion, pleurodynia and hepatitis.[1]
Viral Structure and Function
Coxsackie B viruses are single-strange positive-sense RNA viruses that are resistant to a wide variety of chemical treatments. The viral particles themselves are roughly 30nm icosahedrons.[2] The virus is most frequently distributed via the fecal-oral route, and infection commonly occurs after eating contaminated food. Coxsackie B viruses are cytolytic, and Coxsackie B2 and B5 viruses have been implicated in hand, foot and mouth disease as well as respiratory infection.[1] Infection in infants is mostly asymptomatic, but sometimes results in the death of the infant, often due to myocarditis.[3] Birth defects may also be present in a coxsackie B infected infant.
Associated Conditions
- The B4 strain of coxsackie viruses has been discovered to be a possible cause of Diabetes mellitus type 1.
- Sjogren's syndorme is also thought to have a connections with coxsackie B virus.
- Coxsackie B3 and B4 are related to acute flaccid myelitis.[4]
Epidemiology and Demographics
The various members of the Coxsackie B group were discovered almost entirely in the United States, appearing originally in Connecticut, Ohio, New York, and Kentucky, although a sixth member of the group has been found in the Philippines.[1] That said, all six serotypes have a global distribution and are a relatively common cause of gastrointestinal upset.
Diagnosis
History and Symptoms
Symptoms of infection with viruses in the Coxsackie B grouping include fever, headache, sore throat, gastrointestinal distress, as well as chest and muscle pain. This presentation is known as pleurodynia or Bornholmes disease in many areas. Patients with chest pain should see a doctor immediately as it can progress to myocarditis or pericarditis, which result in permanent heart damage or death. Coxsackie B virus infection may also induce aseptic meningitis. As a group, they are the most common cause of unexpected sudden death, and may account for up to 50% of such cases.[5] The incubation period for the Coxsackie B viruses is, like most of the Enteroviridae, highly variable, ranging from 2 to 35 days, and illness may last for up to two weeks, but may resolve as quickly as two days. Infection usually occurs between the months of June and October.[1]
Laboratory Findings
Enterovirus infection is diagnosed mainly via serological tests such as ELISA[6] and from cell culture.[1] Because the same level and type of care is given regardless of type of Coxsackie B infection, it is mostly unnecessary for treatment purposes to diagnose which virus is causing the symptoms in question, though it may be epidemiologically useful.
Treatment
Medical Therapy
As of 2007, there is no treatment for the Coxsackie B group of viruses.[1] Pallative care is available, however, and patients suffering chest pain or stiffness of the neck should be examined for signs of cardiac or central nervous system involvement, respectively. Some measure of prevention can usually be achieved by basic sanitation on the part of food-service workers, though the viruses are highly contagious. Care should be taken in washing ones hands and in cleaning the body after swimming. In the event of Coxsackie-induced myocarditis or pericarditis, antiinflammatories can be given to reduce damage to the heart muscle. There is no vaccine for any member of the group.
Prevention
