High trait shame undermines the protective effects of prevalence knowledge on state shame following HPV/CIN diagnosis in women.

Human papillomavirus (HPV), and the related, cervical intraepithelial neoplasia (CIN), are common yet poorly understood physical conditions. The diagnosis of HPV often elicits shame and guilt, which in turn may undermine psychological and physical health. The current study compared shame and guilt responses to diagnosis among two groups: women diagnosed with HPV/CIN and women diagnosed with Epstein-Barr Virus (EBV/IM). Eighty women recently diagnosed with HPV/CIN or EBV/IM completed measures of shame- and guilt-proneness, shame and guilt following diagnosis, and disease knowledge including prevalence estimates (HPV and EBV, respectively). HPV/CIN (vs. EBV/IM) predicted more diagnosis-related shame and guilt. Estimates of high prevalence interacted with diagnosis and shame-proneness to predict diagnosis-related shame. Simple slope analyses indicated that in women with HPV/CIN reporting low-to-average shame-proneness, high prevalence estimates reduced diagnosis-related shame; however, women high in shame-proneness experienced high diagnosis-related shame regardless of more accurate prevalence estimates. Women high in shame-proneness appear to be particularly vulnerable to HPV-related shame even when they are aware that it is very common.

Seropositivity of neurotropic infectious agents in first-episode schizophrenia patients and the relationship with positive and negative symptoms.

BACKGROUND: According to the neurodevelopmental model, schizophrenia is a disorder that occurs as a result of different etiologic factors during brain development, including viral infections. However, it is unclear whether these infections are related to the disease or whether they affect the symptom pattern. We investigated the presence of four herpes viruses (EBV, CMV, HSV-1 and HSV-2) in first-episode schizophrenia patients and compared seropositive with seronegative patients and healthy volunteers to reveal the etiological role of viral agents on schizophrenia symptoms. SUBJECTS AND METHODS: Ninety-two first-episode patients who met the DSM-IV diagnostic criteria for schizophreniform disorder were included the study, along with 88 healthy volunteers. The presence of the four herpes viruses was investigated with serological methods (ELISA) in both groups. Positive and negative symptoms were evaluated with Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS). RESULTS: There was no difference between the patient and control groups in terms of seropositivity of the four viruses. We found that SANS scores of HSV-1 and CMV seropositive schizophrenia patients were significantly higher than the scores of patients with seronegative schizophrenia. No difference was found in SAPS scores. CONCLUSIONS: The results suggest a role of HSV and CMV infections in negative symptoms. This supports the hypothesis that viruses do not directly give rise to schizophrenia, but patients who were previously been infected with these viral agents may be prone to schizophrenia, and some of the symptom patterns may be related to different agents.

Population levels of psychological stress, herpesvirus reactivation and HIV.

Nearly 40,000 Americans are newly infected with Human Immunodeficiency Virus (HIV) each year. Recently, studies have demonstrated associations between group-level characteristics and the prevalence and incidence of HIV/Acquired Immune Deficiency Syndrome (AIDS) and other sexually transmitted diseases. Two mechanisms previously posited to explain these associations are neighborhood effects on risk behaviors and social or institutional policies. In this paper, we hypothesize that adversity at the population level, such as neighborhood poverty, also influences HIV risk through stress-mediated aberrations in immunological susceptibility by reviewing existing data examining each of these pathways. In particular, we review the evidence showing that: (1) Neighborhood ecologic stressors influence neighborhood- and individual-levels of mental health, psychosocial stress, and HIV/AIDS risk, (2) Individual-level psychosocial stressors influence progression from HIV to AIDS through stress-related hormonal changes, and (3) Individual-level psychosocial stressors influence HIV acquisition via stress-related reactivation of latent herpesviruses, specifically EBV and HSV-2. Our review indicates that further studies are needed to examine the joint pathways linking neighborhood-level sources of psychosocial stress, stress-related reactivation of HSV-2 and EBV, and increased acquisition rates of HIV. We suggest using a multi-level framework for targeting HIV prevention efforts that address not only behavioral risk factors, but structural, political, and institutional factors associated with neighborhood disadvantage, levels of psychosocial stress, and prevention or treatment of HSV-2 and EBV.

Epstein-Barr virus (EBV) reactivation and therapeutic inhibitors.

Epstein-Barr virus (EBV) is a ubiquitous human virus which infects almost all humans during their lifetime and following the acute phase, persists for the remainder of the life of the individual. EBV infects B lymphocytes leading to their immortalisation, with persistence of the EBV genome as an episome. In the latent phase, EBV is prevented from reactivating through efficient cytotoxic cellular immunity. EBV reactivates (lytic phase) under conditions of psychological stress with consequent weakening of cellular immunity, and EBV reactivation has been shown to occur in a subset of individuals with each of a variety of cancers, autoimmune diseases, the autoimmune-like disease, chronic fatigue syndrome/myalgic encephalitis and under other circumstances such as being an inpatient in an intensive care unit. Chronic EBV reactivation is an important mechanism in the pathogenesis of many such diseases, yet is rarely tested for in immunocompetent individuals. This review summarises the pathogenesis of EBV infection, EBV reactivation and its role in disease, and methods which may be used to detect it. Known inhibitors of EBV reactivation and replication are discussed, including drugs licensed for treatment of other herpesviruses, licensed or experimental drugs for various other indications, compounds at an early stage of drug development and nutritional constituents such as vitamins and dietary supplements.

Lamotrigine-induced drug reaction with eosinophilia and systemic symptoms (DRESS) during primary Epstein-Barr virus (EBV) infection.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe, potentially life-threatening idiosyncratic drug reaction that may result in skin eruption, mucous membrane involvement, eosinophilia, atypical lymphocytosis and lymphadenopathy, with wide-ranging internal organ involvement. The authors report the case of a 21-year-old man who was prescribed lamotrigine for anxiety disorder. After 2 weeks of treatment, he developed a pruritic morbilliform rash on his trunk and upper extremities that was associated with fever, sore throat, bilateral scleral injection, nausea, vomiting and abdominal pain. A laboratory work-up revealed elevated transaminases and atypical lymphocytosis. He was found to have an active Epstein-Barr virus infection. Lamotrigine was discontinued due to suspicion of DRESS; the patient received pulsed intravenous methylprednisolone followed by oral prednisone taper, which resulted in a significant improvement of symptoms. At follow-up 3 weeks later, signs and symptoms had completely resolved. Follow-up laboratory tests revealed that liver dysfunction had normalised.

Psychiatric symptoms and cognitive dysfunction caused by Epstein-Barr virus-induced encephalitis.

Epstein-Barr virus (EBV) encephalitis is rare and shows a wide range of clinical manifestations. We report an immunocompromised patient with EBV encephalitis diagnosed by EBV-specific PCR and antibody testing in the cerebrospinal fluid who presented with psychiatric symptoms and cognitive dysfunction in the absence of any neurological impairments or infectious signs. Clinical recovery and clearance of cerebrospinal fluid EBV DNA appeared following ganciclovir treatment within 6 weeks.

Persistent preceding focal neurologic deficits in children with chronic Epstein-Barr virus encephalitis.

Epstein-Barr virus encephalitis is a self-limiting disease with few sequelae. Persistence of neurologic deficits prior to and after the acute illness has yet to be described in children. We describe five children with persistent cognitive and focal neurologic deficits due to chronic Epstein-Barr virus encephalitis with various T2-weighted magnetic resonance imaging abnormalities. Clinical features were a 9-year-old boy with aphasia and apraxia, an 11-year-old girl with impulsivity and inappropriate behavior, a 17-year-old boy with deterioration of cognitive skills and judgment, a 5-year-old boy with complex-partial seizures, and a 6-year-old girl with obsessive-compulsive behavior. All patients had elevated serum Epstein-Barr virus titers for acute infection, with cerebrospinal fluid polymerase chain reaction positive for Epstein-Barr virus in four patients. Three children were treated with methylprednisolone with minimal improvement without changes on magnetic resonance imaging. Epstein-Barr virus encephalitis can present with chronic and insidious neurologic symptoms and should be considered in the differential diagnosis of children with acute or chronic neurologic illness of unknown etiology.

Maternal depression and Epstein-Barr virus reactivation in early pregnancy.

OBJECTIVE: Recent evidence suggests a link between Epstein-Barr virus reactivation and chronic stress due to decreased cellular immune responses. Maternal depression complicates 10% to 20% of pregnancies and is accompanied by stress. We sought to estimate the association of Epstein-Barr virus reactivation with depression in pregnancy. METHODS: In this cohort study, prevalence of Epstein-Barr virus reactivation was compared between 100 pregnant women with depression before pregnancy and a computer-generated referent group of 100 healthy women not known to be depressed. We included only those women with documented Diagnostic and Statistical Manual of Mental Disorders depression diagnoses in the current pregnancy. Serum samples were analyzed for presence of Epstein-Barr virus viral capsid antigen, nuclear antigen, and early antigen antibodies. Epstein-Barr virus reactivation was defined by presence of viral capsid antigen or nuclear antigen immunoglobulin (Ig) G, along with early antigen IgG, viral capsid antigen IgM, or both early antigen IgG and viral capsid antigen IgM. RESULTS: Maternal demographics were similar between the groups except for older age (34.1 compared with 32.7 years, P=.05), and lower body mass index (27.3 compared with 28.9, P=.03) among the depressed individuals. Ninety-five percent of the women were seropositive for Epstein-Barr virus. Women with depression were more likely to have Epstein-Barr virus reactivation (48% compared with 30%, P=.01) when compared with referent participants. Epstein-Barr virus reactivation remained associated with maternal depression (adjusted odds ratio 1.97, 95% confidence interval 1.10-3.77, P=.03) after controlling for potential confounders. CONCLUSION: Women with depression have higher prevalence of Epstein-Barr virus reactivation, possibly due to increased stress. LEVEL OF EVIDENCE: II.

Stress-associated immune dysregulation and its importance for human health: a personal history of psychoneuroimmunology.

Historically, clinicians have suspected that both major and minor stressful events can have health implications. Observations and case reports link severely stressful life events with a sudden onset or worsening of a variety of illnesses. The immune system was quickly implicated as a means to help explain how stressful life events could produce this relationship. The field of psychoneuroimmunology (PNI) is a field of research that deals with the complex interactions between the central nervous system, endocrine and immune systems, and how behavior/stress can modify these interactions. In this review, I have selected some of our papers that represent our efforts to study the effects of stress on the immune response and also include selected papers that describe how our PNI program at The Ohio State University Medical Center has evolved; virtually all of this research has been performed in collaboration with Janice Kiecolt-Glaser and others in our research group.

Production of pro-inflammatory cytokines correlates with the symptoms of acute sickness behaviour in humans.

BACKGROUND: Elaboration of the concept of cytokine-induced sickness behaviour in recent years has opened new avenues for understanding brain involvement in sickness and recovery processes. Additionally, this has led to much speculation about the role of the immune system in neuropsychiatric syndromes, including depression and chronic fatigue. However, few studies have examined this phenomenon as it naturally occurs in sick humans, and none has attempted to document the quantitative relationships between cytokine levels and non-specific symptoms. The aim of this research was to examine human sickness behaviour and its immunological correlates in documented Epstein-Barr virus (EBV), Q fever or Ross River virus (RRV) infections. METHOD: We studied two separate samples. The first consisted of 21 patients with acute Q fever. The second included 48 patients with acute RRV or EBV infection. Psychological and somatic symptom profiles were derived from self-report measures completed at enrolment. Quantification of proinflammatory cytokines [interleukin (IL)-1beta and IL-6] in sera and supernatants of peripheral blood mononuclear cell (PBMC) cultures was undertaken by specific ELISAs. RESULTS: Levels of IL-1beta and IL-6 spontaneously released from PBMC cultures were consistently correlated with reported manifestations of acute sickness behaviour including fever, malaise, pain, fatigue, mood and poor concentration. CONCLUSIONS: IL-1beta and IL-6 produced as part of the host response represent sensitive markers of sickness behaviour in humans with acute infection. Further work is needed to systematically characterize the spectrum and natural history of sickness behaviour in humans and to elucidate its biological basis.
