Aseptic meningitis
Résumé
Aseptic meningitis is the inflammation of the meninges, a membrane covering the brain and spinal cord, in patients whose cerebral spinal fluid test result is negative with routine bacterial cultures. Aseptic meningitis is caused by viruses, mycobacteria, spirochetes, fungi, medications, and cancer malignancies. The testing for both meningitis and aseptic meningitis is mostly the same. A cerebrospinal fluid sample is taken by lumbar puncture and is tested for leukocyte levels to determine if there is an infection and goes on to further testing to see what the actual cause is. The symptoms are the same for both meningitis and aseptic meningitis but the severity of the symptoms and the treatment can depend on the certain cause.
The most common cause of aseptic meningitis is by viral infection. Other causes may include side-effects from drugs and connective tissue disorders.
Aseptic meningitis is a disease that can depend on the patient's age, however, research has shown some distinct symptoms that indicate the possibility of aseptic meningitis. A variety of patients notice a change in body temperatures (higher than normal temperatures 38-40 °C), marked with the possibility of vomiting, headaches, firm neck pain, and even lack of appetite. In younger patients, like babies, a meningeal inflammation can be noticed along with the possibility of hepatic necrosis and myocarditis. In serious cases, a multiple organ failure can also signal aseptic meningitis and oftentimes, in babies, seizures and focal neurological deficits can be early symptoms of aseptic meningitis. In fact, in newborns, the mortality rate is 70%. The next set of age group, like children, have similar but varying symptoms of sore throat, rashes, and diarrhea. In adults, symptoms and the harshness of them tend to be less in duration. Additionally, the probability of developing aseptic meningitis increases when patients have a case of mumps or herpes.
Symptoms of meningitis caused by an acute viral infection last between one and two weeks.
