Autoimmune hepatitis (AIH) is an immune-mediated, inflammatory liver disease. Clinical presentation of AIH in children is highly variable. It can present acutely, chronically, or silently. There are two main types of AIH-type 1 and type 2, which are differentiated and defined by the presence of specific autoantibodies. AIH eventually progresses to cirrhosis when left untreated, and occasionally even with treatment. AIH must be suspected and excluded in all children presenting with signs of acute, prolonged, or severe liver disease...

Parvovirus B19 (PVB19) is a virus found in the skin that causes asymptomatic infections and can exist in the host for long periods to time. The virus induces a local inflammatory response and is associated with the development of arthritis and other autoimmunes diseases. Parvovirus B19 DNA was investigated by PCR in the skin of 20 patients with psoriasis and 20 patients with eczema. Additionally, immunohistochemistry was used to characterize the expression of cytokines in these lesions. The sociodemographic variables were similar in the two groups studied...

Brucellosis is the most common zoonosis in the world and it is caused by ingestion of foods contaminated by Brucella spp. that is able to avoid the immune system and can involve every organ system. The bacteria may affect the Central Nervous System (CNS) directly or using phagocytic cells with the way of the "Trojan Horse Model". Meningitis is the most common form of neuro-brucellosis (NB) but other neurological manifestation, with variable onset, such as severe encephalic involvement, neuropathy, vascular damage, radiculitis and hydrocephalus might happened...

In common variable immunodeficiency (CVID) there is a deregulation of the immune system, which frequently leads to an increased risk of infections, but also to autoimmunity phenomena. Autoimmune hepatitis may develop at any time of CVID's evolution, but it is difficult to diagnose due to the frequent absence of autoantibodies and low levels of IgG. Early diagnosis is important because targeted treatment may allow disease improvement. We present a case of autoimmune hepatitis in a patient with CVID.

Purpose Treatment of advanced non-small-cell lung cancer with immune checkpoint inhibitors (ICIs) is characterized by durable responses and improved survival in a subset of patients. Clinically available tools to optimize use of ICIs and understand the molecular determinants of response are needed. Targeted next-generation sequencing (NGS) is increasingly routine, but its role in identifying predictors of response to ICIs is not known. Methods Detailed clinical annotation and response data were collected for patients with advanced non-small-cell lung cancer treated with anti-programmed death-1 or anti-programmed death-ligand 1 [anti-programmed cell death (PD)-1] therapy and profiled by targeted NGS (MSK-IMPACT; n = 240)...

Subjective social isolation, loneliness, is associated with poor mental and physical health, but the underlying molecular mechanisms are poorly understood. Here we analyzed loneliness data collected on average 5 years ante-mortem and RNA gene expression at death in postmortem dorsolateral prefrontal cortex (DLPFC) from 181 participants in the Rush Memory and Aging Project (MAP), a longitudinal, prospective cohort study of common chronic conditions of aging. Our analytic protocol controlled for biographical variables (age, sex, education), psychological and health variables (depressive symptoms, interval between assessment and autopsy, slope of cognitive decline, AD pathology, presence of infarcts) and RNA integrity...

Immunization against influenza is a critical, but perhaps underappreciated prevention of morbidity and mortality in the cardiac population. The purpose of the present study is to examine influenza vaccination rates in adults with congenital heart disease (ACHD). A secondary purpose is to explore whether there is an association between demographic, medical, and behavioral variables and receipt of the influenza vaccination. Of the 183 consecutive ACHD patients who were contacted, 123 responded to our telephone survey...

Chlamydia is the most common cause of bacterial sexually transmitted infections worldwide. While infections resolve with antibiotic treatment, this is often neglected in women due to frequent asymptomatic infections, leading to disease progression and severe sequelae (pelvic inflammatory disease, ectopic pregnancy, infertility). Development of a vaccine against Chlamydia is crucial. Whole organism-based vaccines have short-lived activity, serovar/subgroup-specific immunity and can cause adverse reactions in vaccinated subjects...

Head and neck cancer (HNC) remains the sixth most common malignancy worldwide and survival upon recurrence and/or metastasis remains poor. HNSCC has traditionally been associated with alcohol and nicotine use, but more recently the Human Papilloma Virus (HPV) has emerged as a favorable prognostic risk factor for oropharyngeal HNSCC. However, further stratification with additional biomarkers to predict patient outcome continues to be essential. One candidate biomarker is the DEK oncogenic protein, which was previously detected in the urine of patients with bladder cancer and is known to be secreted by immune cells such as macrophages...

The rapid emergence of drug resistance, unfavourable immunosuppression and mounting evidence to suggest the deleterious accumulation of drug breakdown residues within animal tissues has driven a strong desire to move away from these current methods of disease control. Some natural products such as β-glucan, which are extracted from, for example, plants and fungi, are able to modulate the immune system and increase protection against diseases. However, these products are heterogeneous and their effects can be variable thus limiting their applicability and reliability...

Wild banded mongooses ( Mungos mungo) in northeastern Botswana and northwest Zimbabwe are infected with a novel Mycobacterium tuberculosis complex (MTC) pathogen, Mycobacterium mungi. We evaluated gross and histologic lesions in 62 infected mongooses (1999-2017). Many tissues contained multifocal irregular, lymphohistiocytic to granulomatous infiltrates and/or multifocal or coalescing noncaseating to caseating granulomas with variable numbers of intralesional acid-fast bacilli. Over one-third of nasal turbinates examined had submucosal lymphohistiocytic to granulomatous infiltrates, erosion and ulceration of the nasal mucosa, bony remodeling, and nasal distortion...

Primary immunodeficiencies (PIDs) are low-incidence diseases caused by defects in genes involved in the development, maintenance, and regulation of the immune system. Common variable immunodeficiency (CVID) is the most common symptomatic immunodeficiency of adulthood. It has an approximate prevalence of 1 in 25 000-50 000 in the general population, with a delay in diagnosis between 6-7 years. The clinical manifestations of CVID constitute six main categories: infections, pulmonary complications, granulomatous or polyclonal lymphocytic disease, autoimmunity, gastrointestinal diseases and malignancy Most patients must have at least one of the following clinical manifestations (infection, autoimmunity, lymphoproliferation)...

Rosanna Dammacco
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology and with remarkably heterogeneous clinical features. Virtually any organ system can be affected, including the eye. SLE-related eye involvement can be diagnosed in approximately one-third of the patients and is usually indicative of disease activity. An early diagnosis and the adoption of suitable therapeutic measures are necessary to prevent sight-threatening consequences, especially in patients with juvenile SLE. Periocular lesions, such as eyelid involvement and orbital inflammation, are relatively rare and, in case of orbital masses, may require a biopsy control...

BACKGROUND: Elizabethkingia miricola is a rare Gram-negative bacterium found in water and clinical specimens. Typical culturing methods often misidentify Elizabethkingia spp. as Flavobacterium or Chryseobacterium. Although diagnosis is based on culturing samples taken from sterile sites, such as blood, a proper identification of this bacterium requires an expertise that goes beyond the capabilities of a typical clinical laboratory. CASE PRESENTATION: A 35-year-old woman diagnosed with common variable immunodeficiency was admitted to our center...

Delayed-type hypersensitivity to systemically administered corticosteroids is rare. Corticosteroids are unique allergens, potentially leading to atypical manifestations. They are commonly used for treatment of allergic, inflammatory and autoimmune diseases because of intrinsically immunosuppressive and immune-modulatory properties (1). These properties may counterbalance, mask and delay allergic reactions as has been shown (1). It has been speculated that allergic reactions to corticosteroids may remain unrecognized due to their broad clinical variability or frequently atypical presentation (1)...

BACKGROUND: Despite the availability of a safe and efficacious vaccine against HPV, uptake of the vaccine in the United States is low. Missed clinical opportunities to recommend and to administer HPV vaccine are considered one of the most important reasons for its low uptake in adolescents, however, little is known about the frequency or characteristics of missed opportunities in the young adult (18-26 years of age) population. OBJECTIVES: To assess both the rates of and the factors associated with missed opportunities for HPV immunization among young adult women who attended an urban obstetrics and gynecology clinic...

The immune system is delegated to defend the body from attacks from outside or inside. Many diseases can affect immune system reducing its ability to defend self or inducing an abnormal response against external or internal antigens. Rare diseases affecting immune system present some issue in common with other rare diseases and some peculiarities due to the huge variability in the disease's expression. However, a correct estimation of the epidemiology of rare disorders is necessary for evaluating the prognosis and the responses to new therapies, for planning proper public health services, and finally to establish fair and sustainable prices for innovative medicines...

Fifty years after the discovery of Epstein-Barr virus (EBV), it remains unclear how primary infection with this virus leads to massive CD8 T-cell expansion and acute infectious mononucleosis (AIM) in young adults. AIM can vary greatly in severity, from a mild transient influenza-like illness to a prolonged severe syndrome. We questioned whether expansion of a unique HLA-A2.01-restricted, cross-reactive CD8 T-cell response between influenza virus A-M158 (IAV-M1) and EBV BMLF1280 (EBV-BM) could modulate the immune response to EBV and play a role in determining the severity of AIM in 32 college students...

Common Variable Immune Deficiency (CVID) is rare. It is a constitutional deficit of humoral immunity characterized by recurrent bacterial infections and by increased frequency of tumors, autoimmune or granulomatous diseases. Gastrointestinal manifestations are very variable and sometimes reveal common variable immune deficiency.

Females have a longer lifespan and better general health than males. Considerable number of studies also demonstrated that, after trauma and sepsis, females present better outcomes as compared to males indicating sex-related differences in the innate immune response. The current notion is that differences in the immuno-modulatory effects of sex hormones are the underlying causative mechanism. However, the field remains controversial and the exclusive role of sex hormones has been challenged. Here, we propose that polymorphic X-linked immune competent genes, which are abundant in the population are important players in sex-based immuno-modulation and play a key role in causing sex-related outcome differences following trauma or sepsis...
