In recent years, stroke-induced immunodepression syndrome (SIDS) and the resulting stroke-associated infection (SAI) have become a focus of current research efforts. Inflammatory reactions after stroke promote tissue healing and eliminate necrotic cells, whereas excessive inflammatory reactions may cause secondary damage. Stroke-induced immunodepression not only reduces inflammatory reactions and protects brain tissues but also weakens the resistance of the human body against pathogens and leads to infection...

The Zika virus (ZIKV) epidemic has recently emerged as public health threat due to its teratogenic nature and association with the serious neurological condition Guillain-Barré syndrome (GBS). To date, no approved antiviral therapeutics or vaccines are available to confront ZIKV. In order to develop effective anti-ZIKV vaccines, improved animal models and a better understanding of immunological correlates of protection against ZIKV are required. In this paper, we discuss the recent progress in developing vaccines against ZIKV and the hurdles to overcome in making efficacious anti-Zika vaccines...

Objective: The aim was to study the therapeutic effects and mechanisms of QWRG on adjuvant-induced RA in rats. Methods: The RA rat models were manipulated and subsequently divided into five experimental groups: AIA, DEX, and QWRG groups. The paw volume, body weight, arthritic score, and mechanical nociceptive threshold were assessed. The serum levels of the RF, MDA, ALP, AST, ALT, IL-1β, IL-2, IL-16, and TNF-α were measured. The proliferative capacity of lymphocytes was evaluated, and the synovial tissue was histopathologically examined...

Herpesvirus infections are not uncommon in hematologic patients. Our first patient, diagnosed with chronic lymphatic leukemia, presented extensive genital herpes infection refractory to treatment with acyclovir and with a partial response to foscarnet, which had to be withdrawn due to systemic adverse effects. The second patient, diagnosed with follicular Hodgkin lymphoma, presented hypertrophic herpes infection refractory to treatment with acyclovir but that responded to intralesional cidofovir and topical imiquimod...

The refusal of treatment is frequent in human immunodeficiency virus-positive adolescents. The clinical history of a teenage girl presenting severe immunodepression secondary to the virus, a depressive disorder and a refusal of treatment, illustrates the benefit of combined paediatric, child psychiatric and cross-cultural care as proposed by the Cochin-Paris Adolescent Centre. Working on the meaning of the refusal was a prerequisite for the construction of a care project forming part of a life project, as the psychopathological work could only begin once somatic care ensuring the patient's protection was in place...

Most studies on bacterial virulence focus on the pathogen itself. However, it is important to recall that the in-host behavior and the virulence of bacterial pathogens constitute a complex situation that depends on both the microorganisms and the infected host. While healthy people (the community) is infected by classical pathogenic microorganisms, able to cope with the anti-infection defenses of the host, in the case of people with basal diseases, debilitated or immunodepressed, the range of pathogens able to cause infection is wider and includes the so-named opportunistic pathogens, which lack the inherent ability to cause disease in healthy hosts and rarely produce infections in the community...

The production of Manila clam (Ruditapes philippinarum) is seriously threatened by the protistan parasite Perkinsus olseni. We characterized and compared gene expression of Manila clam haemocytes in response to P. olseni in a time-course (10 h, 24 h, 8 d) controlled laboratory challenge (LC), representing the first step of infection, and in a more complex infection in the wild (WI), using a validated oligo-microarray containing 11,232 transcripts, mostly annotated. Several immune-genes involved in NIK/NF-kappaB signalling, Toll-like receptor signalling and apoptosis were activated at LC-10 h...

Given the abundance of stroke patients and deaths from stroke worldwide, many studies concerning the aftermath of stroke are being carried out. To reveal the precise effect of ischemic infarction, we conducted a comprehensive gene expression analysis. Alongside a middle cerebral artery occlusion (MCAO) Sprague-Dawley rat model, we used a group undergoing sham surgery for comparison, which was the same as MCAO surgery but without blood vessel occlusion. Subsequently, infarction of the brains of MCAO-treated rats occurred, but did not occur in the sham-treated rats...

BACKGROUND: Cutaneous squamous cell carcinoma (CSCC) develops on the head in 80% of cases. Parotid metastasis (PM) is rare, but treatment, which associates surgery and radiation therapy, is heavy and prognosis poor. MATERIAL AND METHODS: All cases of parotidectomy for PM of CSCC of the head and neck between 2005 and 2015 were studied retrospectively. Epidemiologic, oncologic and therapeutic data were analyzed. Overall and specific survival were calculated following Kaplan-Meier...

RATIONALE: Acute hepatitis E virus (HEV) infections are usually self-limiting in immunocompetent patients. HEV persistence has been described only in immunosuppressed patients such as solid-organ transplant recipients, patients with hematological diseases, or patients with human immunodeficiency virus (HIV) infection. PATIENT CONCERNS: A 61-year-old patient was admitted in hospital for jaundice and asthenia. DIAGNOSES: The patient had underlying cirrhosis and developed a chronic HEV infection...

Demodex mites are commensal organisms rarely found in healthy children. Human demodicosis can be classified as a primary or a secondary form. The secondary form in children usually affects severely immunodepressed children. To our knowledge, this is the first report of human demodicosis associated with Langerhans cell histiocytosis. These cases show that this skin disorder can occur months after completing chemotherapy, without recurrence of the systemic disease.

The endosymbiont-host relationship between a pea crab and its bivalve host has been studied previously using bivalve's multi-physiological parameters. The present study is first of its kind that uses hemocyte's immune functionality to evaluate the symbiotic relationship between bivalve Paphia malabarica and its symbiont crab, Pinnotheres vicajii. The sampling was carried out at two stations (differed in nutrient concentration, productivity, and bacterial abundance) located along the southwest coast of India...

Tuberculosis (TB) is a global health issue, with a rising incidence since the beginning of this century. It poses a severe mortality risk and also poses a serious economic risk as it reduces the working capacity of an individual in the most productive part of life. Developing countries face widespread tuberculosis infection - up to 95% of all cases and 98% of deaths, respectively. It is a highly contagious infectious disease caused by Mycobacterium tuberculosis (the Koch bacillus) that can be contracted from either humans or animal hosts...

INTRODUCTION: Nocardia is an opportunist bacteria involved in patients with cellular immunodepression or chronic lung disease. The most frequent portals of entry are the respiratory tract by inhalation or direct inoculation through a cutaneous effraction. Nocardiosis may be localised or disseminated. CASE REPORT: We report a rare case of disseminated nocardiosis to Nocardia nova with pulmonary, cutaneous, cerebral attacks and femoral osteomyelitis. The diagnosis was confirmed by prolonged cultures of the bronchoalveolar fluid and the pus extracted from a cutaneous lesion...

Pneumocystis jirovecii is an unusual ascomycetous fungus that can be detected in the lungs of healthy individuals. Transmission from human to human is one of its main characteristics in comparison with other fungi responsible for invasive infections. P. jirovecii is transmitted through the air between healthy individuals, who are considered to be the natural reservoir, at least transiently. In immunocompromised patients, P. jirovecii multiplies, leading to subacute infections and acute life-threatening pneumonia, called Pneumocystis pneumonia [PCP]...

BACKGROUND: Skin cancer occurs frequently in organ transplant patients as a result of induced immunosuppression. Most cases involve carcinomas or B-cell lymphomas induced by the Epstein Barr virus (EBV). Cutaneous T-cell lymphomas remain rare. We report a case of cutaneous T-cell lymphoma of the mycosis fungoides type in a heart transplant recipient. PATIENTS AND METHODS: A 68-year-old man who had received a heart transplant 21years earlier and was being treated with tacrolimus, mycophenolate mofetil and prednisolone had been presenting a psoriasiform rash on his trunk, limbs and head for 4years...

Melatonin, a pineal gland hormone, exerts oncostatic activity in several types of human cancer, including prostate, the most common neoplasia and the third most frequent cause of male cancer death in the developed world. The growth of androgen-sensitive LNCaP prostate cancer cells in mice is inhibited by 3 mg/kg/week melatonin (0.09 mg/mouse/week) delivered by i.p. injections, which is equivalent to a dose of 210 mg/week in humans. The aim of this study is to test an alternative noninvasive delivery route based on transdermal administration of melatonin onto the tumor area followed by cryopass-laser treatment...
