Adenovirus type 12 was recovered from the CSF of a 36-year-old woman with adenoviral meningoencephalitis and lead toxicity. The serum level of lead was 199 micrograms/dL and the CSF level was 7 micrograms/dL. After therapy with edetate disodium calcium (Calcium Disodium Versenate), she had an uneventful recovery. The possibility of exacerbation of lead poisoning with encephalopathy due to adenovirus type 12 meningoencephalitis is raised.

Adenovirus infections are very common diseases, especially upper respiratory infections and diarrhea in infants. Moreover, adenoviruses can occasionally produce CNS infections. The common causative adenovirus is type 7 for them, and they have been associated with pneumonia and epidemics of adenovirus in family outbreaks. Reye-like syndrome has rarely been reported. As AIDS and other immunocompromised patients have increased, new reports of adenovirus CNS infections have also increased. Of course the immunosuppressed conditions have included lymphoma, transplant etc. In the near future, long term care for immunocompromised patients will have a crisis of adenovirus CNS infection. On the other hand, adenovirus CNS infections are difficult to diagnose precisely without special facilities, due to the need for adenovirus cultivation from CSF. In addition, the diagnosis may have limitations due to the many subtypes of adenovirus. Despite the benefits of PCR methods, standard laboratory testing procedures are still not established for diagnosis.

Adenovirus-mediated gene transfer into the brain is associated with significant inflammation and activation of anti-vector and anti-transgene immune responses that curtail the gene delivery of adenoviruses and therapeutic efficacy. Elucidating the molecular mediators of inflammatory and immune responses to adenoviruses injected into the brain should allow us to inhibit their inflammatory actions, thereby reducing vector clearance and enhance adenoviral-mediated gene transfer into the CNS. Cytokines are primary mediators of the immune response and are released during inflammation. Here we report for the first time that injection of replication-deficient adenovirus vectors into the cerebral ventricles of rats causes a rapid increase in body temperature. This fever response precedes any vector-encoded transgene expression and occurs with vectors encoding no transgene, as well as with vectors encoding a therapeutic transgene i.e., HSV1-thymidine kinase. No fever is detected after infection of the striatum, an important brain target in studies on neurodegeneration. After infection of the brain ventricles, CSF levels of immunoreactive tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta increase significantly (up to 300-fold). In the hypothalamus, the locus of thermoregulation in the brain, only IL-1beta and IL-6 are significantly elevated. A neutralizing TNF-alpha antibody has no effect on adenovirus-induced fever. However, pretreatment with either the IL-1 receptor antagonist or the cyclooxygenase inhibitor flurbiprofen completely abolishes adenovirus-induced fever, suggesting that IL-1 and prostaglandins are direct mediators of this response. These results are the first to demonstrate that IL-1, but not TNF-alpha, is the main mediator of a very early inflammatory response to adenovirus in the brain.
