Active clinical trials for "Infections"

Prospective, observational study of the microbiology of patients referred to a tertiary care center with severe acute tonsillitis, peritonsillar cellulitis, or infectious mononucleosis.

Between 2009 and January 2016, the investigators included 49 patients from four hospitals in Lyon who had a Total Knee Arthroplasty (TKA) infection and who benefited of a knee arthroplasty revision with a rotating hinge prosthesis. This retrospective and descriptive cohort aims at studying the functional results after 2 years follow up.

This is single center study. The investigators will try to know that relationships between intestinal microbiome and mortality in preterm infants and what relationships is between intestinal microbiome in preterm infants and morbidity, mortality.

Community-acquired pneumonia (CAP) is a heterogeneous disease causing great morbidity, mortality and health care burden globally. Typing methods for discriminating different clinical conditions of the same disease are essential to a better management of CAP. Traditional typing systems based separately on clinical manifestations (such as PSI and CURB-65), pathogens(bacterial types, virulence, drug resistance, etc) or host immune state (immunocompetent, immunocompromised or immunodeficiency). Thus, they are barely able to represent the real disease status nor to precisely predict the mortality. As the development of multi-omic technologies, the relatedness of different phenotypes at a molecular level have revolutionized our ability to differentiate among patients. Our study is aimed at establishing a novel molecular typing method of CAP. Multi-omic (including genomics, transcriptomes, and metabolisms) data obtained from enrolled CAP patients and isolated pathogens would be integrated analyzed and interpreted. Tthe investigators believe that an appropriate molecular typing method would lead to revolutionary changes in current arrangements of CAP.

Recent observations in Germany revealed above-average high proportions of refugees affected by infectious diseases of public health significance. Scrutiny of the vaccination status showed sizeable presence of seronegative subjects, with conspicuously higher prevalence among children and adolescents, thus indicating urgent necessity of i) rapid identification of carriers of vaccine-preventable diseases and ii) adjustment of protection against such infections to European Standards. Rapid immune status check needs comprehensive diagnostic tool permitting simultaneous assessment of seropositivity. Validation of such tools requires comparisons of the immune status of subjects with known vaccination history with that of migrants with incomplete or missing health and vaccination records.

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by low platelet count (i.e less than 100.000) . In ITP, platelet surface membrane proteins become antigenic for unknown reasons , leading to stimulation of the immune system , autoantibody production, and platelet destruction In recent years ,the list of etiologies of ITP has been steadily increasing, so the term "idiopathic" is becoming obsolete, increasingly replaced by "immune"TP . Treatment of ITP may be conceptually divided into rescue therapy and maintenance therapy . the terminology of corticosteroid-dependence means The need for ongoing or repeated doses administration of corticosteroids for at least 2 months to maintain a platelet count at or above 30 _ 109/L and/or to avoid bleeding. So, patients with corticosteroid dependence are considered non responders

The study will identify the epidemiological and treatment profiles of acute peritonitis in Italy

Not all infectious agents have the same epidemic potential, and this can vary widely within the same species. Rapid determination of this potential is essential to optimize control of infectious diseases. It is now accepted that identification with the species is clearly insufficient to identify an epidemic and to carry out epidemiological analyzes. Indeed, if the same bacterial species can present a great diversity of strains, it is organized in clonal complexes having strong variations of clinical and epidemiological expression. More specifically, on a bio-epidemiological level, the clonal identification of the bacterial agent is a real asset because it can make it possible to identify the highly virulent strains or known to be resistant, the clones associated with nosocomial infections, the source of the infection. an epidemic and to follow its spatio-temporal extension, to know the epidemiological antiquity of the clone, to follow or rebuild a chain of transmission, to discover epidemic clusters. There are rapid identification techniques, for example by polymerase chain reaction (PCR), but which are targeted at particular genomic compositions previously identified. Routine bacterial identification now rests on the determination of the protein composition by mass spectrometry (MALDI-TOF). The bacterial spectrum is compared to a reference library of protein composition, thus obtaining an identification equivalent to that based on the 16s RNA (ribonucleic acid 16s) and can descend to an infra-species level. The aim of this work is to use the proteome part of the MALDI-TOF spectrum to identify peaks that signal clonality and to determine proteomic fingerprintings that can be used for epidemiological and clinical purposes. Instead of relying on expensive genomic methods, the identification of the clonal characteristics of the strains will rely on the bacterial proteome present on the MALDI-TOF spectrum that is produced during the routine identification of the bacterium. The results are intended to feed a complementary knowledge base

Klebsiella pneumoniae is one of the most common pathogens causing both community-onset and nosocomial infection. More worse, the emergency of Carbapenem-Resistant Klebsiella pneumoniae (CRKP) had cause the clinical therapy be very difficult. However, there is not much empirical data as to the prevalence, risk factors, characteristics,outcomes and the rationality of the current therapy for the Klebsiella pneumoniae infection in China.Thus, the study was aimed to investigate the epidemiology and risk factors, characteristics, outcomes and the rationality of the current therapy for the Klebsiella pneumoniae infection in China.

Due to the emergence of multidrug-resistant micro-organisms in patients with bone and joint infection (BJI), the prescription of off-labeled antibiotics seem to be more and more common as part of routine care. These new antibiotics are, however, more expensive, and there are no precise data in France regarding the volume and cost of such off-label prescriptions in hospital, in the post-acute care structures, and in the outpatient setting. The objective of this study is to estimate the cost of using these antibiotics over 2 years for patients in a reference center for the management of complex bone and joint infection (CRIOAc)
