    Abstract The availability of pathogen-specific treatment options for respiratory tract infections (RTIs) increased the need for rapid diagnostic tests. Besides, retrospective studies, improved lab-based detection methods and the intensified search for new viruses since the beginning of the twenty-first century led to the discovery of several novel respiratory viruses. Among them are human bocavirus (HBoV), human coronaviruses (HCoV-HKU1, -NL63), human metapneumovirus (HMPV), rhinovirus type C (RV-C), and human polyomaviruses (KIPyV, WUPyV). Additionally, new viruses like SARS coronavirus (SARS-CoV), MERS coronavirus (MERS-CoV), novel strains of influenza virus A and B, and (most recently) SARS coronavirus 2 (SARS-CoV-2) have emerged. Although clinical presentation may be similar among different viruses, associated symptoms may range from a mild cold to a severe respiratory illness, and thus require a fast and reliable diagnosis. The increasing number of commercially available rapid point-of-care tests (POCTs) for respiratory viruses illustrates both the need for this kind of tests but also the problem, i.e., that the majority of such assays has significant limitations. In this review, we summarize recently published characteristics of POCTs and discuss their implications for the treatment of RTIs. The second key aspect of this work is a description of new and innovative diagnostic techniques, ranging from biosensors to novel portable and current lab-based nucleic acid amplification methods with the potential future use in point-of-care settings. While prototypes for some methods already exist, other ideas are still experimental, but all of them give an outlook of what can be expected as the next generation of POCTs.

    Abstract Background: Th17 cytokines are associated with modulation of inflammation and may be beneficial in clearing influenza infection in experimental models. The Th17 cytokine profile was evaluated in a pilot study of respiratory virus infections.
    Methods: Consecutive patients with symptoms of respiratory tract infection visiting the emergency department of a tertiary care hospital during the winter influenza season of 2014 to 2015 were evaluated. CLART PneumoVir kit, (GENOMICA, Madrid, Spain) was used for viral detection of all known respiratory viruses. Th17 cytokine profile was evaluated with the MILLIPLEX MAP Human TH17 Magnetic Bead Panel (Millipore Corp., Billerica, MA). Correlation of the TH17 profile with viral detection was performed with univariate and multivariate analysis.
    Results: Seventy-six patients were evaluated (median age 56 years, 51.3% female); a respiratory virus was identified in 60 (78.9%) patients; 45% had confirmed influenza. Influenza A (H3N2) correlated with higher levels of granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 1β (IL-1β), IL-17A, IL-17E, IL-17F, IL-21, IL-22, and IL-23 (P < 0.05 by analysis of variance [ANOVA]) compared with respiratory syncytial virus (RSV). Parainfluenza virus (PIV) similarly had higher levels of GM-CSF, IL-1b, IL-17A, IL-22 compared with those detected in RSV, influenza B and any other virus infection ( P < 0.05; ANOVA). Increasing age (β-coefficient = 1.11, 95% CI, 1.04-1.2, P < 0.01) as well as IL-17A levels (β-coefficient = 1.03, 95% CI, 1.001-1.05, P = 0.04) predicted hospital admission.
    Conclusion: Main Th17 cell effector cytokines were upregulated in laboratory-confirmed A(H3N2) influenza and PIV. Excessive amounts of Th17 cytokines may be implicated in the pathogenesis and immune control of acute influenza and PIV infection in humans and may predict the severity of disease.

    Abstract The current study aimed to describe the molecular epidemiology of mixed respiratory viral infections during consecutive winter seasons in a tertiary care hospital. Patients with symptoms of respiratory tract infection were evaluated during the 2009-2011 and 2013-15 winter seasons. A clinical microarray technique was used for viral detection. Clinical and epidemiological data were correlated with mixed viral detection and the need for hospitalization. In 332 out of 604 (54.4%) evaluated patients (17.6% children) a respiratory virus was identified. Mixed viral infections were diagnosed in 68/332 (20.5%) patients with virus detection (66.2% mixed Influenza-RSV infections). Mixed viral infections were more commonly detected in children (OR 3.7; 95%CI 1.9-5.6, P < 0.01) and patients with comorbidities. In logistic regression analyses, mixed viral infections were associated with younger age (mean age 30.4 years vs. 41.8 years, P ≤ 0.001) and increased rates of fever (OR: 2.7; 95%CI 1.04-7.2, P < 0.05) but no adverse outcomes or increased rates of hospitalization. High rates of mixed viral infections were noted during all winter seasons (especially Influenza and RSV) and were more common in younger patients. The clinical significance of mixed respiratory viral infection needs further elucidation.

    Abstract The first, to our knowledge, case of the aseptic abscesses syndrome as a complication of traveler's diarrhea after a trip to Malaysia is presented. The patient failed to respond to several antimicrobials. The diagnosis was histologically confirmed and the patient only responded to immunomodulatory therapy with corticosteroids and methotrexate. Travel physicians should be aware of this entity reviewed herein in the context of traveler's diarrhea.

    Abstract Human granulocytic anaplasmosis (HGA) is a tick-borne disease caused by Anaplasma phagocytophilum that has the potential to spread in new geographical areas. The first fatal case of HGA in Greece is presented. Fever of unknown origin, renal and respiratory insufficiency and development of macrophage activation syndrome characterized the clinical presentation. Amplification and sequencing of a fragment of the groEL gene revealed the presence of A. phagocytophilum. The epidemiological and clinical features were collected during an epidemiological investigation. Public health measures were instituted by the Hellenic Centre for Disease Control and Prevention. The Public Health intervention required the collaboration of epidemiologists, veterinarians and microbiologists. Emphasis was given to communication activities and misconceptions concerning canines and their role in the disease. The emergence of human anaplasmosis in a new geographical area highlights the importance of disease awareness and of the need for continued support for tick and tick-borne disease surveillance networks.
