Worms have co-evolved with humans over millions of years. To survive, they manipulate host systems by modulating immune responses so that they cause (in the majority of hosts) relatively subtle harm. Anthelminthic treatment has been promoted as a measure for averting worm specific pathology and to mitigate subtle morbidities which may include effects on anaemia, growth, cognitive function and economic activity. With our changing environment marked by rapid population growth, urbanisation, better hygiene practices and anthelminthic treatment, there has been a decline in worm infections and other infectious diseases and a rise in non-communicable diseases such as allergy, diabetes and cardiovascular disease...

Patients at a high-risk of severe influenza, because of their underlying health disorders, are recommended to receive a seasonal influenza vaccination. In Poland, influenza coverage rate in the general population is very low (3.4 %). However, there is little known about the coverage rate among high-risk patients. The aim of this study was to describe a general knowledge, perception, and influenza vaccination coverage rate among Polish patients with enhanced risk for influenza. We conducted a self-reported survey among 500 patients with chronic disorders: 120 pulmonary, 80 hemodialyzed, 100 thyroid cancer, and 200 cardiovascular patients...

BACKGROUND: The incidence of herpes zoster (HZ) is increasing and poses a significant health concern to aging populations. Several studies suggest an increased risk of stroke following zoster infection, but the results are conflicting. We conducted a systematic review and meta-analysis to determine if stroke risk is increased following HZ infection. METHODS: A search of MEDLINE, EMBASE, Google scholar, Web of Science, CAB Direct, Cumulative Index to Nursing and Allied Health Literature, and Evidence Based Medicine Reviews was conducted for observational studies of adults with HZ infection that examined stroke and TIA risk from January 1, 1966 to May 31, 2016...

Heart failure (HF) is a chronic syndrome characterized by acute exacerbations. There is significant overlap between respiratory infections and exacerbation of underlying HF. Vaccination against respiratory infections in patients with HF could serve as a potential cost-effective intervention to improve patients' quality of life and clinical outcomes. The benefits of influenza vaccination in secondary prevention of ischemic heart disease have been previously studied. However, the evidence for influenza and pneumococcal vaccination specifically in the HF population is less well established...

Viral myocarditis is a common clinical cardiovascular disease mainly induced by coxsackievirus B3 (CVB3) with no effective therapeutic measures. Induction of efficient mucosal immune responses is very critical against CVB3-induced myocarditis. FimH is an Escherichia coli (E. coli)-derived protein, which possesses an M cell-targeting property and functions as a TLR4 agonist. In this study, we introduced the recombinant FimH protein, into our previously developed CVB3 mucosal vaccine chitosan (CS)-pVP1, aiming to provoke more efficient mucosal immune responses and immunoprotection against CVB3-induced myocarditis...

Rhinovirus is a common cause of upper and lower respiratory tract infections in adults, especially among the elderly and immunocompromised. Nevertheless, its clinical characteristics and mortality risks have not been well described. A retrospective analysis on a prospective cohort was conducted in a single teaching hospital center over a one-year period. We compared adult patients hospitalized for pneumonia caused by rhinovirus infection with those hospitalized for influenza infection during the same period...

During the last decade, the development of large clinical and population-based cohorts led to new findings in the epidemiology and the pharmacoepidemiology of immune thrombocytopenia (ITP). The incidence is estimated to 3-4 for 10(5) inhabitants/year, with a slight female predominance and peaks in children and patients after 60 years. The incidence rate is 9 for 10(5) inhabitants/year in males after 75 years. Variations across ethnic groups are discussed. In France, there is a North-South gradient and a peak of incidence during winter suggesting the role of viruses in ITP pathophysiology...

Obesity is associated with multiple comorbidities such as cardiovascular diseases and has a huge economic impact on the health-care system. However, the treatment of obesity remains insufficient in terms of efficacy, tolerability, and safety. Here we created a nasal vaccine against obesity for the first time. To avoid the injectable administration-caused pain and skin-related adverse event, we focused on the intranasal route of antigen delivery. We developed a vaccine antigen (ghrelin-PspA (pneumococcal surface protein A)), which is a recombinant fusion protein incorporating ghrelin, a hormone that stimulates food intake and decreases energy expenditure, and PspA, a candidate of pneumococcal vaccine as a carrier protein...

Cardiovascular diseases remain a major global health issue, with the development of atherosclerosis a major underlying cause. Our treatment of cardiovascular disease has improved greatly over the past 3 decades, but significant need still remains to reduce disease burden. Current priorities include reducing atherosclerosis advancement to clinically significant stages, and preventing plaque rupture or erosion. Inflammation and involvement of the adaptive immune system influences all these aspects and therefore is one focus for future therapeutic development...

All patients with advanced chronic kidney disease or on renal replacement therapy should receive active hepatitis B vaccination. The aim of this retrospective cohort study was to investigate the association between the immune response to hepatitis B vaccination and all-cause, cardiovascular or infection-related mortality in incident dialysis patients starting dialysis between 2001 and 2008 (n=426) in two Austrian dialysis centers. Vaccination response was defined as follows: absent anti-HBs antibody titer or a titer <10IU/L was classified as non-response, seroconversion (SC) was defined as a titer ⩾10IU/L, and seroprotection (SP) as a titer ⩾100IU/L...

For almost 50 years, ebolaviruses and related filoviruses have been repeatedly reemerging across the vast equatorial belt of the African continent to cause epidemics of highly fatal hemorrhagic fever. The 2013-2015 West African epidemic, by far the most geographically extensive, most fatal, and longest lasting epidemic in Ebola's history, presented an enormous international public health challenge, but it also provided insights into Ebola's pathogenesis and natural history, clinical expression, treatment, prevention, and control...

Research in novel drug delivery systems is being explored competitively in order to attain maximum therapeutic effect while minimizing the adverse effects. Despite several advancements in pharmaceutical formulations, one of the major challenges still persisting is sustained drug release. Microencapsulation enacts as an intelligent approach with a strong therapeutic impact and is in demand globally in medical technology due to its specific and attractive properties, including biocompatibility, stability, target specificity, uniform encapsulation, better compliance, and controlled and sustained release patterns that are responsible for diminishing the toxicity and dosage frequency...

BACKGROUND: Cardiovascular disease occurs at lower incidence in premenopausal females compared with age-matched males. This variation may be linked to sex differences in inflammation. We prospectively investigated whether inflammation and components of the inflammatory response are altered in females compared with males. METHODS: We performed 2 clinical studies in healthy volunteers. In 12 men and 12 women, we assessed systemic inflammatory markers and vascular function using brachial artery flow-mediated dilation (FMD)...

Rhesus macaque (Macaca mulatta), because of their similarity to humans, are often used to study complex neurobiology and anatomy, cardiovascular disease, and in vaccine development. While the rhesus genome is studied on its own by primatologists, the grand majority of rhesus macaque research is done with the intention of extrapolating the findings to human diseases and traits. As such, it makes sense that the rhesus genome and karyotype be arranged based on homology to human chromosomes in an effort to ease the comparisons between the two, and aide in interpreting data generated using rhesus macaque model systems...

Immunosenescence, defined as the age-associated dysregulation and dysfunction of the immune system, is characterized by impaired protective immunity and decreased efficacy of vaccines. Immunosenescence affects both the innate and adaptive immune systems; however, the most notable changes are in T cell immunity and include thymic involution, the collapse of T cell receptor (TCR) diversity, an imbalance in T cell populations, and the clonal expansion of senescent T cells. An increasing number of immunological, clinical and epidemiological studies suggest that persistent Cytomegalovirus (CMV) infection is associated with accelerated aging of the immune system and T cell immunosenescence especially...

REVIEW
Marc D Cohen, Edward Keystone
Rituximab is a chimeric monoclonal antibody directed at the CD20 molecule on the surfaces of some but not all B cells. It depletes almost all peripheral B cells, but other niches of B cells are variably depleted, including synovium. Its mechanism of action in rheumatoid arthritis (RA) is only partially understood. Rituximab was efficacious in clinical trials of patients with RA, including those who are methotrexate naïve, those with an incomplete response to methotrexate, and those with an incomplete response to tumor necrosis factor inhibitors...

BACKGROUND: The rodent borne Puumala hantavirus (PUUV) causes haemorrhagic fever with renal syndrome in central and northern Europe. The number of cases has increased and northern Sweden has experienced large outbreaks in 1998 and 2006-2007 which raised questions regarding the level of immunity in the human population. METHODS: A randomly selected population aged between 25 and 74 years from northern Sweden were invited during 2009 to participate in a WHO project for monitoring of trends and determinants in cardiovascular disease...
