BACKGROUND: Splenectomized patients are more prone to bacterial infections due to their immunocompromised status. Little is known about the role of T helper 17 (Th17) and T regulatory cells (Treg) in the immune system of patients after the removal of the spleen. OBJECTIVES: The aim of the present study was to analyze possible changes in CD4+ lymphocyte T subsets, especially Treg and Th17, in patients who had undergone splenectomy. MATERIAL AND METHODS: The study included a group of 67 male patients (41...

Background and Aims: Vedolizumab, a humanised monoclonal antibody for the treatment of inflammatory bowel disease, selectively blocks gut lymphocyte trafficking. This may reduce the risk of respiratory tract infections [RTIs] compared with systemic immunosuppressive therapies. To assess this possibility, we evaluated the rates of RTIs in clinical trials of vedolizumab. Methods: Patient-level data from Phase 3 randomised controlled trials [RCTs] of vedolizumab in ulcerative colitis [UC; GEMINI 1] and Crohn's disease [CD; GEMINI 2], and a long-term safety study [UC and CD] were pooled...

Background: Paramyxoviruses include respiratory syncytial virus (RSV), parainfluenza virus (PIV), and human metapneumovirus (MPV), which may cause significant respiratory tract infectious disease (RTID) and mortality after allogeneic hematopoietic cell transplantation (HCT). However, clinical data regarding frequency and outcome are scarce. Methods: We identified all paramyxovirus RTIDs in allogeneic HCT recipients diagnosed by multiplex polymerase chain reaction between 2010 and 2014...

The canid parasites Eucoleus aerophilus (syn. Capillaria aerophila) and Eucoleus boehmi (syn. Capillaria boehmi) parasitize the lower and the upper respiratory tract, respectively. Reports and descriptions of these nematodes are scarce in Argentina, possibly due to misdiagnosis of morphologically similar trichuroids eggs, and the lack of knowledge about the species of Eucoleus in this geographical area. Scanning electron microscopy is a useful tool for identification of E. boehmi eggs based on the characteristics of the shell structure which differentiate between species...

IgA vasculitis is a small-vessel vasculitis mediated by immune complexes. In clinical terms, it is characterized by palpable purpura in the lower limbs, joint involvement in the form of arthralgia or arthritis, and gastrointestinal and renal involvement (this will mark a poorer prognosis in adults). Infectious processes, mainly in the upper respiratory tract, are frequently found to be triggers. On the other hand, human immunodeficiency virus (HIV) causes immune dysfunction, which triggers hypergammaglobulinemia and can trigger autoimmune disorders...

BACKGROUND: FebriDx is a 10-minute disposable point-of-care test designed to identify clinically significant systemic host immune responses and aid in the differentiation of bacterial and viral respiratory infection by simultaneously detecting C-reactive protein (CRP) and myxovirus resistance protein A (MxA) from a fingerstick blood sample. FebriDx diagnostic accuracy was evaluated in the emergency room and urgent care setting. METHODS: A prospective, multicentre, observational cohort study of acute upper respiratory tract infections (URIs), with and without a confirmed fever at the time of enrolment, was performed to evaluate the diagnostic accuracy of FebriDx to identify clinically significant bacterial infection with host response and acute pathogenic viral infection...

OBJECTIVE: Antibiotics are widely prescribed in the Emergency Department (ED), representing 26-62% of outpatient antibiotic prescriptions. Around 40% of antibiotic prescriptions in hospitalized patients are inappropriate or unnecessary. The aim of the study was to assess the appropriateness of antibiotic prescriptions according to local empirical antibiotic treatment guidelines, in the ED of a tertiary hospital. METHODS: Observational, retrospective study including patients attending the ED in November 2016, with an antibiotic prescription, excluding those from residents...

BACKGROUND/OBJECTIVE: Traditional sources cite seasonal patterns for common infectious diseases, often based on microbiologic data, but little is known about cyclical trends in clinically diagnosed infectious conditions in the emergency department (ED). We leveraged the publicly available Nationwide Emergency Department Sample database to measure the seasonality of the most common pediatric infectious diseases diagnosed in US EDs. METHODS: We searched the Nationwide Emergency Department Sample database to identify infectious diagnoses comprising at least 1% of all diagnosis codes ascribed to patients 21 years and younger in US EDs from 2009 to 2013...

BACKGROUND:  Acute upper respiratory tract infections (URTIs) and their complications are the most frequent cause of antibiotic prescribing in primary care. With multi-resistant organisms proliferating, appropriate alternative treatments to these conditions are urgently required. Homeopathy presents one solution; however, there are many methods of homeopathic prescribing. This review of the literature considers firstly whether homeopathy offers a viable alternative therapeutic solution for acute URTIs and their complications, and secondly how such homeopathic intervention might take place...

A number of important Gram-negative pathogens that reside exclusively in the upper respiratory or genitourinary tract of their mammalian host rely on surface receptors that specifically bind host transferrin and lactoferrin as a source of iron for growth. The transferrin receptors have been targeted for vaccine development due to their critical role in acquiring iron during invasive infection and for survival on the mucosal surface. In this study, we focus on the lactoferrin receptors, determining their prevalence in pathogenic bacteria and comparing their prevalence in commensal Neisseria to other surface antigens targeted for vaccines; addressing the issue of a reservoir for vaccine escape and impact of vaccination on the microbiome...

BACKGROUND: Influenza viruses are undergoing continuous and rapid evolution. The fatal influenza A/H7N9 has drawn attention since the first wave of infections in March 2013, and raised more grave concerns with its increased potential to spread among humans. Experimental studies have revealed several host and virulence markers, indicating differential host binding preferences which can help estimate the potential of causing a pandemic. Here we systematically investigate the sequence pattern and structural characteristics of novel influenza A/H7N9 using computational approaches...

Porcine pleuropneumonia is an important cause of lowered productivity and economic loss in the pig industry worldwide, associated primarily with Actinobacillus pleuropneumoniae infection. Its colonization and persistence within the upper respiratory tract of affected pigs depends upon interactions between a number of genetically controlled virulence factors, such as pore-forming repeats-in-toxin exoproteins, biofilm formation, and antimicrobial resistance. This study investigated correlations between biofilm-forming capacity, antimicrobial resistance, and virulence of A...

BACKGROUND: Information on the duration of replicative Middle East respiratory syndrome coronavirus (MERS-CoV) shedding is important for infection control. Detection of MERS-CoV subgenomic mRNAs indicates the virus is replicative. We examined the duration for detecting MERS-CoV subgenomic mRNA compared with genomic RNA in diverse respiratory specimens METHODS: From upper and lower respiratory samples of 17 MERS-CoV-infected patients, MERS-CoV subgenomic mRNA was detected by reverse transcription polymerase chain reaction (RT-PCR) and MERS-CoV genomic RNA was done by real time RT-PCR...

Introduction: Professional sleep associations recommend 7-9 h of sleep per night for young adults. Habitually sleeping less than 6 h per night has been shown to increase susceptibility to common cold in otherwise healthy, adult civilians. However, no investigations have examined the importance of sleep duration on upper respiratory tract infection (URTI) and loss of training days in military recruits. The purpose of this study was to describe self-reported sleep duration in a large cohort of military recruits and to assess the relationship between reported sleep duration and incidence of URTI's...

REVIEW
Paul T King
Bronchiectasis is a prevalent respiratory condition characterised by permanent and abnormal dilation of the lung airways (bronchi). There are a large variety of causative factors that have been identified for bronchiectasis; all of these compromise the function of the immune response to fight infection. A triggering factor may lead to the establishment of chronic infection in the lower respiratory tract. The bacteria responsible for the lower respiratory tract infection are usually found as commensals in the upper respiratory tract microbiome...

Paired NP and MT swabs were obtained from 96 children (mean age 2.45 years) with upper respiratory tract symptoms. Of these, 38.5% were colonized with Streptococcus pneumoniae only, 16.7% with Haemophilus influenzae only, 9.4% with both bacteria. Bacterial cultures from paired NP and MT swabs demonstrated agreement for S. pneumoniae (Kappa=0.75), H. influenzae (K=0.59) and for both pathogens (K=0.62).
