HIV infection and inflammatory and autoimmune diseases (IAD) are both related to immune dysfunction. Epidemiological data on IAD in patients living with HIV (PLHIV) are scarce. The aim of this study was thus to estimate the prevalence of 26 IAD among PLHIV followed in a large French multicenter cohort in the cART era (from January 2000 to July 2013), and to describe their occurrence according to cART onset, the immuno-virological status of patients and HCV and/or HBV co-infection.During the study period, 33 403 PLHIV were included in the Dat'AIDS cohort; 1381 patients with an IAD were identified...

Chagas disease is caused by Trypanosoma cruzi and transmitted by feces of a triatomine that has the habit of defecating during blood feeding. The salivary glands of triatomines are important to hematophagy because their saliva is rich in anticoagulant and hemolytic proteins. The salivary glands of some Rhodnius species analyzed are reddish due to the presence of nitrophorins (antihemostatic activity). The present study aimed to analyze the color pattern of the salivary glands of 67 triatomine species to evaluate whether the presence of nitrophorins is a synapomorphy of Rhodnius or the tribe Rhodniini, or if it is shared with triatomines of the tribes Triatomini and Cavernicolini...

A 70-year-old, immunocompromised patient presented to the emergency room (ER) five weeks after she was started on clopidogrel. She complained of skin eruption, mouth ulcers, fatigue, and myalgia over the past two weeks. Labs showed severe hyponatremia, acute kidney injury, rhabdomyolysis, hyperkalemia, and elevated liver enzymes. She was treated with steroids and discharged after her condition improved. However, a month later, she returned to the ER, complaining of nausea, vomiting, diarrhea, dizziness, chills, and shortness of breath over the past two days...

Thrombotic microangiopathy (TMA) is characterized by the presence of microangiopathic hemolytic anemia and thrombocytopenia along with organ dysfunction, and pathologically, by the presence of microthrombi in multiple microvascular beds. Delays in diagnosis and initiation of therapy are common due to the low incidence, variable presentation, and poor awareness of these diseases, underscoring the need for interdisciplinary approaches to clinical care for TMA. We describe a new approach to improve clinical management via a TMA team that originally stemmed from an Affinity Research Collaborative team focused on thrombosis and hemostasis...

BACKGROUND: Hemolytic uremic syndrome (HUS) can occur as a primary process due to mutations in complement genes or secondary to another underlying disease. HUS sometimes occurs in the setting of glomerular diseases, and it has been described in association with Denys-Drash syndrome (DDS), which is characterized by the triad of abnormal genitourinary development; a pathognomonic glomerulopathy, diffuse mesangial sclerosis; and the development of Wilms tumor. CASE PRESENTATION: We report the case of a 46, XX female infant who presented with HUS and biopsy-proven thrombotic microangiopathy...

PURPOSE OF REVIEW: This review aims to highlight recent advances in our understanding of how anti-red blood cell (RBC) antibodies prevent erythrocyte immunization with an emphasis on new murine models. RECENT FINDINGS: New murine models with clinically relevant human erythrocyte antigens have been used to understand the alloimmunization process and its inhibition. The search to elucidate the mechanism of action of IgG-mediated inhibition of erythrocyte alloimmunization has provided new evidence in support of a potential role for epitope masking, immune deviation and/or antigen modulation in this process...

New regulations concerning EHEC/VTEC Hemolytic Uremic Syndrome (HUS) is the most severe complication to an infection with EHEC (enterohemorrhagic E. coli), also called VTEC (verocytotoxin-producing E. coli). Risk of severe complications such as HUS is an important reason why the Swedish Communicable Diseases Act (Smittskyddslag. 2004:168) includes infection with EHEC. With very few exceptions, only EHEC with the stx2 gene is associated with HUS. According to the law, persons working with unpackaged foods, infants or severely immunocompromised patients, and children attending preschool can be suspended awaiting negative test results for EHEC...

Vibrio alginolyticus has been associated with several diseases of cultivated marine animals, and has led to considerable economic losses. The oligopeptide permease (Opp) has been proven to play a variety of important roles in nutrition and virulence in several bacteria. In our previous research, the opp gene cluster was identified in Vibrio alginolyticus with transcriptome sequence, which also indicated that the Opp system might play roles in the regulation of adhesion. In this study, the relationship between V...

Faecalibacterium prausnitzii is a major member of the Firmicutes phylum and one of the most abundant bacteria in the healthy human microbiota. F. prausnitzii depletion has been reported in several intestinal disorders, and more consistently in Crohn's disease (CD) patients. Despite its importance in human health, only few microbiological studies have been performed to isolate novel F. prausnitzii strains in order to better understand the biodiversity and physiological diversity of this beneficial commensal species...

Cell-free hemoglobin (Hb), a well-known marker of intravascular hemolysis, is eventually oxidized to methemoglobin (MtHb). Elevated levels of MtHb have been noted, alongside depleted levels of platelets, in several hemolytic diseases. The current study aims to probe the possible role of MtHb in platelet death, based on the facts that it is a pro-inflammatory and pro-apoptotic agent, as well as the sensitive nature of platelets and their tendency to undergo apoptosis under oxidative stress. Consequently an attempt is made to establish the link between hemolysis and thrombocytopenia, by deciphering the underlying molecular signaling pathways...

There are only a few reports of successful use of mammalian target of rapamycin (mTORI) as primary immunosuppression in pediatric heart transplantation. Compared to calcineurin inhibitors, mTORI have less side effects, especially nephrotoxicity, infections and malignancies. A retrospective study was conducted at our institution of all 170 heart transplants from 1995-2015. Nineteen patients were switched from tacrolimus(n=15) or cyclosporin(n=4) to everolimus(n=4) or sirolimus(n=15) due to nephrotoxicity(n=5), malignancy(n=8), EBV viremia/reactive plasmacytic changes(n=5) and immune hemolytic anemia(n=1)...

Thrombotic thrombocytopenic purpura (TTP) is rare but life-threatening disease, characterized typically by microangiopathic hemolytic anemia (MAHA), profound peripheral thrombocytopenia and severe deficiency in the von Willebrand factor-cleaving prortease ADAMTS13. It has been reported that acquired immune TTP is closely associated with human immunodeficiency virus infection and influenza infection or vaccination. However, it has not been reported to be associated with Epstein Barr Virus infection or reactivation...

Diabetes mellitus (DM) is a chronic and metabolic disease that presents a high global incidence. Glycated hemoglobin (A1C) is the reference test for long-term glucose monitoring, and it exhibits an association with diabetic chronic complications. However, A1C is not recommended in clinical situations which may interfere with the metabolism of hemoglobin, such as in hemolytic, secondary or iron deficiency anemia, hemoglobinopathies, pregnancy, and uremia. The glycated albumin (GA) is a test that reflects short-term glycemia and is not influenced by situations that falsely alter A1C levels...

Alzheimer's disease (AD), a neurodegenerative disorder, is a serious medical issue worldwide with drastic social consequences. Inhibition of cholinesterase is one of the rational and effective approaches to retard the symptoms of AD and, hence, consistent efforts are being made to develop efficient anti-cholinesterase agents. In pursuit of this, a series of 19 acetamide derivatives of chromen-2-ones were synthesized and evaluated for their acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory potential...

REVIEW
Yonggoo Kim, Joonhong Park, Myungshin Kim
Inherited hemolytic anemias (IHAs) are genetic diseases that present with anemia due to the increased destruction of circulating abnormal RBCs. The RBC abnormalities are classified into the three major disorders of membranopathies, hemoglobinopathies, and enzymopathies. Traditional diagnosis of IHA has been performed via a step-wise process combining clinical and laboratory findings. Nowadays, the etiology of IHA accounts for germline mutations of the responsible genes coding for the structural components of RBCs...

REVIEW
Marta Kłos, Jadwiga Wójkowska-Mach
Group C streptococci (GCS) are livestock pathogens and they often cause zoonotic diseases in humans. They are Gram-positive, in mostly β-hemolytic and facultative anaerobes. Because of their close evolutionary kinship with group A streptococci (GAS), GCS share many common virulence factors with GAS and cause a similar range of diseases. Due to the exchange of genetic material with GAS, GCS belong to bacteria that are difficult to be distinguished from group A streptococci; GCS are often treated in microbiological diagnostics as contamination of the culture...

Complement protein C3 is the pivotal component of the complement system. Previous studies have demonstrated that C3 has implications in various human diseases and exerts profound functions under certain conditions. However, the delineation of pathological and physiological roles of C3 has been hampered by the insufficiency of suitable animal models. In the present study, we applied the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated (Cas) system to target the C3 gene in porcine fetal fibroblasts...
