Total IgG subclass levels, anti-viral, anti-myelin basic protein (anti-MBP), and anti-ganglioside 1 (anti-GM1) IgG subclass levels were measured in 6 patients with herpes simplex virus encephalitis (HSVE), 16 with borreliosis, 8 with other bacterial infections, 12 with multiple sclerosis (MS), 13 with subacute sclerosing panencephalitis (SSPE), 5 with glioblastoma and 12 controls. Total IgG1 levels were elevated in cerebrospinal fluid (CSF) from all patient groups (but not in the controls), IgG2 in bacterial infections, IgG3 in HSVE and borreliosis and IgG4 in some SSPE patients. The anti-viral (anti-measles, varicella zoster virus and rubella) IgG antibodies in MS were restricted to IgG1, anti-measles IgG to IgG1 and sometimes IgG4 in SSPE, anti-borrelia IgG to IgG1, IgG2 and IgG3. In contrast to anti-viral antibodies, anti-MBP and GM1 antibodies belonged to IgG1, IgG3 or IgG4 in MS. The nature of the immunological activation appears to be reflected in the subclass patterns elicited in the central nervous system. Different IgG subclass patterns in infectious diseases and MS suggest a difference between antigen-specific and non-specific B-cell activation.

The authors previously reported statistically significant inverse associations between adult onset glioma and histories of chickenpox and shingles among 462 cases and 443 controls in the San Francisco Bay Area Adult Glioma Study (1991--1995) and a suggestive but nonsignificant inverse association with immunoglobulin G antibodies to varicella-zoster virus in a small subset of these cases. This report considers antibodies to four common herpesviruses (varicella zoster, herpes simplex, cytomegalovirus, and Epstein Barr) among 134 cases and 165 controls that represent all subjects for whom usable blood specimens were available. The prevalences of immunoglobulin G antibodies to varicella-zoster virus, herpes simplex virus, cytomegalovirus, and Epstein-Barr virus were 90%, 71%, 57%, and 90%, respectively. After adjustment for age, White versus non-White ethnicity, and gender, glioblastoma cases were less likely than controls to have immunoglobulin G antibodies to varicella-zoster virus (odds ratio = 0.4; 95% confidence interval: 0.1, 0.9). They were also somewhat less likely to have antibodies to Epstein-Barr virus but somewhat more likely to have antibodies to herpes simplex virus and cytomegalovirus. Antibody prevalences to all four herpesviruses were similar between cases with other glioma histologies and controls. These results corroborate our previously suggestive findings of an inverse association of varicella-zoster virus antibodies with adult onset glioma.

Whether viruses or immunologic factors might cause or prevent human brain cancer is of interest. Statistically significant inverse associations of adult glioma with history of chickenpox and immunoglobulin G antibodies to varicella-zoster virus have been reported. The authors evaluate associations of immunoglobulin G antibodies to varicella-zoster virus and three other herpesviruses among 229 adults with glioma and 289 controls in the San Francisco Bay Area Adult Glioma Study (1997-2000). Cases were less likely than controls to report a history of chickenpox (for self-reported cases vs. controls: the age-, gender-, and ethnicity-adjusted odds ratio = 0.59, 95% confidence interval: 0.40, 0.86), and they also had lower levels of immunoglobulin G to varicella-zoster virus (for being in the highest quartile vs. the lowest quartile: the age-, gender-, and ethnicity-adjusted odds ratio = 0.41, 95% confidence interval: 0.24, 0.70). The inverse association with anti-varicella-zoster virus immunoglobulin G was most marked for glioblastoma multiforme cases versus controls and was only somewhat attenuated by excluding subjects taking high-dose steroids and other medications. Cases and controls did not differ notably for positivity to three other herpesviruses, Epstein-Barr virus, cytomegalovirus, and herpes simplex virus. Cohort studies may help to clarify the nature of the association between immunity to and/or clinical manifestations of varicella-zoster virus and glioblastoma.

Renal transplantation is method of choice for treatment of patients with end-stage renal disease without contraindications for immunosuppressive therapy. Neurological complications occur frequently in renal transplant recipients. They may be the consequence of immunosuppressive treatment, but more often evolve as the consequence of previous disturbances which developed during the state of uraemia and treatment with dialysis. The most pronounced neurotoxic effect has calcineurin inhibitors tacrolimus and cyclosporine. The spectrum of neurological disturbances caused by calcineurin inhibitors range from very mild symptoms as paraesthesiae, tremor, headache or flushing, to severe changes that may cause lethal outcome. Peripheral neuropathies in renal transplant recipients may occur in the form of mononeuropathy or polyneuropathy. Cerebrovascular diseases are consequence of changes on blood vessels caused by uraemia, dialysis and side effects of immunosuppressive drugs. They cause death in 8% of renal transplant recipients. Central nervous system (CNS) infections usually occur during the first posttransplant year. Unclear symptomatology frequently postpones the diagnosis. Diagnostic evaluation should include magnetic resonance imaging for localization of the process, as well as lumbal puncture in cases without contraindications for the procedure, in order to determine the causative agent. Regarding the ominous prognosis of CNS infections in the immunocompromised host, only timely diagnosis may improve survival. The most common causative agents are Cryptococcus neoformans, Listeria monocytogenes and Aspergillus funigatus. Viral infections also occur, and are commonly caused by herpes virideae, varicella-zoster virus and papova virus. CNS infections clinically present as meningitis, progressive dementia or focal neurological defect. The most common primary brain tumors are B-cell lymphomas, but glioblastoma, hemangioblastoma, leiomyosarcoma or glioma may also occur. In cases of neurological posttransplant complications, optimal treatment should be guided by neurologist, nephrologist and infectologist, in some cases also by neurosurgeons.
