- OBJECTIVES: Infections are a common cause of hospitalization in breast cancer patients. We studied the risk, clinical characteristics and outcomes of infection-related hospitalizations in this patient population. METHODS: A Swedish registry-based study including 8338 breast cancer patients diagnosed between 2001 and 2008, followed prospectively for infection-related hospitalizations until 2010. Standardized incidence ratios (SIRs) were calculated using background rates from the general female population. Associations with clinical characteristics and mortality were analyzed using flexible parametric survival models. RESULTS: In total, 720 patients experienced an infection-related hospitalization during a median follow-up of 4.9 years. Infection rates were highest within the first year of diagnosis (SIR = 5.61, 95% CI; 4.98-6.32), and site-specific risks were most pronounced for sepsis (SIR = 3.14, 95% CI; 2.66-3.71) and skin infections (SIR = 2.80, 95% CI; 2.24-3.50). Older age at diagnosis, comorbidities, markers of tumor aggressiveness, chemotherapy and axillary node dissection were independent predictors of infectious disease risk. Infection-related hospitalizations were also independently associated with overall and breast cancer-specific death. CONCLUSIONS: A significant number of breast cancer patients are hospitalized with an infection following diagnosis, which in turn predicts poor prognosis. The risk profile of infection-related hospitalizations is multifactorial, including patient, tumor and treatment-related factors.

- © 2019 Elsevier Ltd Objectives: To study the frequency of vertically acquired occult hepatitis B virus (HBV) infection (OBI). Methods: We investigated 44 children born to hepatitis B surface antigen (HBsAg) positive mothers. They received HBV vaccine directly after birth and at 2, 6 and 52 weeks of age; eight with HBeAg-positive mothers also received hepatitis B immunoglobulin (HBIG). HBV DNA was analyzed in blood collected at 6 weeks and 12 months of age, and HBV antibodies at 12 and 18 months of age. Results: HBV DNA, but not HBsAg or anti-HBc, was detected at 12 months of age in three children. The viral sequences were almost identical with HBV DNA from their mothers who all were HBeAg-positive and had received tenofovir during pregnancy. Follow-up at 5–7 years age showed that one of the three children had become seropositive for HBsAg and anti-HBc. This child and one of the other two had detectable HBV DNA at the follow-up, with whole genome sequences identical to those in HBV from their mothers. Conclusions: Mothers-to-child transmission of HBV can, despite adequate prophylaxis, lead to OBI which may later develop into overt HBV infection. Whether such infections are of clinical importance needs to be further investigated.

- Both varicella and herpes zoster that are caused by varicella-zoster virus (VZV), are associated with central nervous system disease. Since the introduction of polymerase chain reaction, the opportunity to detect the virus in cerebrospinal fluid (CSF) has improved dramatically. As a result VZV is diagnosed as one of the most common viruses causing CNS disease and it has become evident that this disease includes a wide spectrum of different CNS manifestations. The most evaluated CNS manifestations are encephalitis which is associated with both varicella and herpes zoster and, cerebellitis which occurs predominantly in children with varicella. Other manifestations have been less widely investigated. The incidence of cerebrovascular disease caused by VZV has been only scarcely studied and, in addition, some data indicate that vasculitis might also be involved in other VZV CNS manifestations such as herpes zoster-associated encephalitis. For this reason, VZV CNS infection must be suspected in several CNS syndromes and diagnostics should be based on CSF analysis for detection of VZV DNA by PCR and/or intrathecal antibody production. The prognosis is reported as favourable in children but few follow-up studies are available. Moreover, in adults, the prognosis is reported to be good in overall terms, but later studies indicate more serious neurological sequelae including cognition. Despite considerable mortality and morbidity, so far also in vaccinating countries, few treatment studies are available. Further treatment studies including assessments of neurological and cognitive sequelae, are warranted.

- Context: The Greater Stockholm HIV Cohort Study is an initiative to provide longitudinal information regarding the health of people living with HIV. Objective: Our aim was to explore the prevalence of HIV and its association with psychiatric co-morbidities. Design, setting and participants: All patients with a recorded diagnosis of HIV ( any position of the ICD-10 codes B20-B24) were identified during the period 2007-2014 and related to the total population in Stockholm by January 1, 2015, N = 2.21 million. The age at diagnosis, gender, and first occurrence of an HIV diagnosis was recorded. Analyses were done by age and gender. Prevalence of psychiatric co-morbidities amongst HIV patients were recorded. Main outcome measures: Age-adjusted odds ratios with 95% confidence intervals were calculated with logistic regression for prevalent psychiatric co-morbidities in HIV infected individuals compared to the prevalence in the general population. Results: The total prevalence of HIV was 0.16%; females 0.10% (n Z 1134) and males 0.21% (n Z 2448). HIV-infected people were more frequently diagnosed with psychiatric illnesses and drug abuse. In females and males with HIV-diagnosis respectively, drug dependence disorder was 7.5 (7.76% vs 1.04%) and 5.1 (10.17% vs 1.98%) times higher, psychotic disorders were 6.3 (2.65% vs 0.42%) and 2.9 (1.43% vs 0.49%) times higher, bipolar disorder was 2.5 (1.41% vs 0.57%) and 3 (1.02% vs 0.34%) times higher, depression diagnosis was 1.5 (8.47% vs 5.82%) and 3.4 (10.17% vs 2.97%) higher, trauma-related disorder was 1.5 (6.00% vs 4.10%) respectively 2.9 (4.45% vs 1.56%) times higher, anxiety disorder was 1.2 (6.88% vs 5.72%) and 2.2 (6.54% vs 2.93%) times higher than in their non-infected peers. Conclusion: Despite effective ART, many individuals with HIV have an impaired mental health and a history of drug abuse that may threaten the vision of a contained epidemic.

- Background: Recent international guidelines recommend vaccination with a 13-valent pneumococcal conjugate vaccine to reduce the risk of meningitis after neurotrauma with cerebrospinal fluid leak. The antibody response and optimal time point for vaccination have not been established and because the risk of meningitis is at the highest shortly after trauma, early vaccination is preferable. This study aimed to investigate the antibody response and to ensure that central nervous system injury-induced immunodepression did not affect the response to a T-cell-dependent conjugate vaccine when administered shortly after the injury. Methods: So as not to interfere with routine pneumococcal vaccination, a conjugate vaccine against Haemophilus influenza type b (Hib) was chosen for the study. Thirty-three patients with basilar skull fracture and 23 patients undergoing transsphenoidal pituitary gland surgery were vaccinated within 10 days after trauma/surgery and 29 control patients at least three weeks after trauma/surgery. Sera were collected pre- and post-vaccination for analysis of anti-Hib concentration. Results: Four patients with post-vaccination target antibody concentration before vaccination were excluded from analysis. In the neurotrauma and neurosurgery groups 10/32 (31%) and 5/20 (25%) patients, respectively, were non-responders compared with 3/29 (10%) in the control group. Log(10) anti-Hib concentrations in the neurotrauma, neurosurgery and control groups were 1.52 +/- 0.15, 1.38 +/- 0.15 and 1.81 +/- 0.12 mu g/ml, respectively. Conclusions: The majority of the patients responded to vaccination. However, the number of responders was significantly decreased and antibody concentration significantly lower in patients vaccinated early after the trauma/surgery. Investigation of the pneumococcal conjugate vaccine response in neurotrauma patients is therefore urgent. (C) 2015 The British Infection Association. Published by Elsevier Ltd. All rights reserved.
