The causes of glioma, the most common type of primary malignant brain tumor, are poorly understood. This study compared the personal and first-degree familial medical histories of 462 adults newly diagnosed with glioma in the San Francisco Bay Area between August 1, 1991, and March 31, 1994, with those of 443 controls who were frequency-matched on age, sex, and ethnicity. Cases and controls had equivalent personal histories of cancers other than brain cancer and most nervous system conditions, but they differed significantly regarding histories of epilepsy, seizures, or convulsions 3 or more years prior to diagnosis (odds ratio = 3.3, 95% confidence interval (CI) 1.4-7.9), chickenpox (odds ratio = 0.4, 95% CI 0.3-0.6), and shingles (odds ratio = 0.5, 95% CI 0.3-0.8). Four cases (less than 1%) and no controls had known genetic disorders (three had neurofibromatosis and one had tuberous sclerosis). Cases and controls had similar family histories of cancer and seizures. However, the odds ratio for a validated family history of primary brain tumor was 2.3 (95% CI 1.0-5.8). These results suggest that although family history of any cancer probably is not an important risk factor for adult glioma, a family history of brain tumors may play a role. Variation in exposure to or biologic response to common viral infections might play a greater role in the etiology of adult glioma than family history.

To evaluate a possible association between varicella-zoster virus infection and glioma, the authors asked adults with glioma (n = 462) whose tumors were diagnosed between August 1, 1991, and March 31, 1994, and age-, sex-, and ethnicity-matched controls (n = 443) about their histories of chickenpox or shingles. Cases were significantly less likely than controls to report a history of either chickenpox (odds ratio = 0.4, 95% confidence interval (CI) 0.3-0.6) or shingles (odds ratio = 0.5, 95% CI 0.3-0.8). To obtain serologic support for these findings, the authors conducted double-blind enzyme-linked immunosorbent assays for immunoglobulin G antibodies to varicella-zoster virus among 167 self-reporting subjects for whom blood samples were available. Cases and controls reporting no history of chickenpox were equally likely to test positive (73% vs. 75%), but among those reporting a positive history, cases were less likely than were controls to test positive (71% vs. 85%). Despite the misclassification, an odds ratio of 0.6 was obtained using either serologic data (95% CI 0.3-1.3) or reported history of chickenpox (95% CI 0.3-1.1) in this subgroup of subjects. This suggests that adults with glioma were less likely than controls either to have had prior varicella-zoster virus infection or to have an immunoglobulin G antibody response adequate to indicate positivity. Since either explanation suggests novel mechanisms for brain tumor pathogenesis, these findings require corroboration and elaboration.

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.

The transfer factor (TF) was described in 1955 by S. Lawrence. In 1992 Kirkpatrick characterized the specific TF at molecular level. The TF is constituted by a group of numerous molecules, of low molecular weight, from 1.0 to 6.0 kDa. The 5 kDa fraction corresponds to the TF specific to antigens. There are a number of publications about the clinical indications of the TF for diverse diseases, in particular those where the cellular immune response is compromised or in those where there is a deficient regulation of the immune response. In this article we present our clinical and basic experiences, especially regarding the indications, usage and dosage of the TF. Our group demonstrated that the TF increases the expression of IFN-gamma and RANTES, while decreases the expression of osteopontine. Using animal models we have worked with M. tuberculosis, and with a model of glioma with good therapeutic results. In the clinical setting we have worked with herpes zoster, herpes simplex type I, herpetic keratitis, atopic dermatitis, osteosarcoma, tuberculosis, asthma, post-herpetic neuritis, anergic coccidioidomycosis, leishmaniasis, toxoplasmosis, mucocutaneous candidiasis, pediatric infections produced by diverse pathogen germs, sinusitis, pharyngitis, and otits media. All of these diseases were studied through protocols which main goals were to study the therapeutic effects of the TF, and to establish in a systematic way diverse dosage schema and time for treatment to guide the prescription of the TF.

A personal history of asthma or allergy has been associated with a reduced risk for adult malignant gliomas. Recent reports on the use of nonsteroidal anti-inflammatory drugs (NSAID) and the presence of risk alleles in asthma susceptibility genes showed similar inverse associations. To further explore the relationship between immune mediators and gliomas, we examined the use of NSAID and antihistamines, history of asthma or allergy, and infection in 325 glioma cases and 600 frequency-matched controls from the metropolitan area of Houston, TX (2001-2006). The regular use of NSAID was associated with a 33% reduction in the risk for glioma, suggestive of possible antitumor activity. Surprisingly, regular long-term antihistamine use among those reporting a history of asthma or allergies was significantly associated with a 3.5-fold increase in the risk for glioma. Similar to previous reports, cases in our study were less likely to have reported asthma, allergy, or a history of a number of viral infections (chickenpox or shingles, oral herpes, and mononucleosis) than controls. We therefore speculate that the observed positive association with antihistamine use may reflect an alteration of protective immune factors in susceptible individuals. Our results lend additional support for an important but unknown link between malignant brain tumors and immune mediators.

The glioma pathogenesis-related 1 (GLIPR1) family consists of three genes [GLIPR1, GLIPR1-like 1 (GLIPR1L1), and GLIPR1-like 2 (GLIPR1L2)] and forms a distinct subgroup within the cysteine-rich secretory protein (CRISP), antigen 5, and pathogenesis-related 1 (CAP) superfamily. CAP superfamily proteins are found in phyla ranging from plants to humans and, based largely on expression and limited functional studies, are hypothesized to have roles in carcinogenesis, immunity, cell adhesion, and male fertility. Specifically data from a number of systems suggests that sequences within the C-terminal CAP domain of CAP proteins have the ability to promote cell-cell adhesion. Herein we cloned mouse Glipr1l1 and have shown it has a testis-enriched expression profile. GLIPR1L1 is posttranslationally modified by N-linked glycosylation during spermatogenesis and ultimately becomes localized to the connecting piece of elongated spermatids and sperm. After sperm capacitation, however, GLIPR1L1 is also localized to the anterior regions of the sperm head. Zona pellucida binding assays indicate that GLIPR1L1 has a role in the binding of sperm to the zona pellucida surrounding the oocyte. These data suggest that, along with other members of the CAP superfamily and several other proteins, GLIPR1L1 is involved in the binding of sperm to the oocyte complex. Collectively these data further strengthen the role of CAP domain-containing proteins in cellular adhesion and propose a mechanism whereby CAP proteins show overlapping functional significance during fertilization.

Procarbazine is effective in the treatment of malignant gliomas. We retrospectively reviewed all glioma patients treated with procarbazine at a dose of 150 mg/m2 daily for 28 days, every eight weeks, to determine incidence and prognostic factors associated with the development of Herpes Zoster. Ten of sixty-four (16%) patients developed Herpes Zoster infections; this group was found to have received a greater number of courses of procarbazine (5.1+/-1.2 v. 1.6+/-.2, p<.001) and have significantly less neutropenia when compared to the group receiving procarbazine who did not develop the infection. Infection developed at a median of 4.1+/-1.1 courses. Herpes Zoster infection is common in brain tumor patients taking procarbazine, and is associated with multiple drug courses and a normal WBC count. Immune function studies that could identify patients at high risk for Herpes Zoster might lead to the prophylactic use of acyclovir.

Glioma is the most common cancer of the central nervous system but with few confirmed risk factors. It has been inversely associated with chicken pox, shingles and seroreactivity to varicella virus (VZV), as well as to allergies and allergy-associated IgE. The role of antibody reactivity against individual VZV antigens has not been assessed. Ten VZV-related proteins, selected for high immunogenicity or known function, were synthesized and used as targets for antibody measurements in the sera of 143 glioma cases and 131 healthy controls selected from the San Francisco Bay Area Adult Glioma Study. Glioma cases exhibited significantly reduced seroreactivity compared to controls for six antigens, including proteins IE63 [odds ratio (OR) = 0.26, 95% confidence interval (CI): 0.12-0.58, comparing lowest quartile to highest) and the VZV-unique protein ORF2p (OR = 0.44, 95% CI: 0.21-0.96, lowest quartile to highest). When stratifying the study population into those with low and high self-reported allergy history, VZV protein seroreactivity was only associated inversely with glioma among individuals self-reporting more than two allergies. The data provide insight into both allergy and VZV effects on glioma: strong anti-VZV reactions in highly allergic individuals are associated with reduced occurrence of glioma. This result suggests a role for specificity in the anti-VZV immunity in brain tumor suppression for both individual VZV antigens and in the fine-tuning of the immune response by allergy. Anti-VZV reactions may also be a biomarker of effective CNS immunosurveillance owing to the tropism of the virus.

Varicella- zoster virus infection is an intriguing medical entity that involves many medical specialties including infectious diseases, immunology, dermatology, and neurology. It can affect patients from early childhood to old age. Its treatment requires expertise in pain management and psychological support. While varicella is caused by acute viremia, herpes zoster occurs after the dormant viral infection, involving the cranial nerve or sensory root ganglia, is re-activated and spreads orthodromically from the ganglion, via the sensory nerve root, to the innervated target tissue (skin, cornea, auditory canal, etc.). Typically, a single dermatome is involved, although two or three adjacent dermatomes may be affected. The lesions usually do not cross the midline. Herpes zoster can also present with unique or atypical clinical manifestations, such as glioma, zoster sine herpete and bilateral herpes zoster, which can be a challenging diagnosis even for experienced physicians. We discuss the epidemiology, pathophysiology, diagnosis and management of Herpes Zoster, typical and atypical presentations.
