Almost half of the hospitalized influenza patients have a chronic disease, which increases the risk for secondary bacterial infections and for adults >65 years influenza is related to high mortality risk. The impact of diabetes mellitus (DM), asthma bronchiale, cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) on the risk of having a low serum phosphatemia (S-P) in addition to influenza is important to investigate as this increases both morbidity and mortality and can be prevented. Hypophosphatemia could be the explanation for reduced chemo-taxis and phagocytosis, which in addition to respiratory function may increase the risk of pneumonia and sepsis. Data for this study was collected from the medical journals retrospectively for 100 patients admitted to the Department of Infectious Diseases during the study period, 1992-94, with the clinical diagnosis influenza out of which seventy-two cases were used in the calculation. Forty-seven percent of the hospitalized influenza patients had a 2.7-fold risk of suffering from DM than of any other chronic disease and an almost significantly doubled risk of having a low S-P level with a chronic disease. The prevalence of hypophosphatemia (S-P<0.70 mmol/l) was high; 13.0% of the women and 15.0% of the men; 34.0% of all patients had S-P<0.82 mmol/l. Men, in contrast to women, showed clinical signs of a secondary bacterial infection more frequently (12/41 and 6/35, respectively). Our study gives indications for an involvement of low S-P with chronic disease.

It is now accepted that an overwhelming inflammatory response is the cause of human deaths from avian H5N1 influenza infection. With this in mind we sought to examine the literature for examples of complementary and alternative medicines that reduce inflammation, and to place the results of this search in the context of our own work in a mouse model of influenza disease, using a pharmaceutical agent with anti-inflammatory properties. Two Chinese herbs, Angelica sinensis (Dang Gui) and Salvia miltiorrhiza (Danshen), have been recently shown to protect mice during lethal experimental sepsis via inhibition of the novel inflammatory cytokine High Mobility Group Box 1 protein (HMGB1). Biochanin A, a ligand of the peroxisome proliferator activated receptors (PPAR) alpha and gamma and the active isoflavone in Trifolium pratense (red clover), has anti-inflammatory properties, and thus could be used as an influenza treatment. This is of great interest since we have recently shown that gemfibrozil, a drug used to treat hyperlipidemia in humans and a synthetic ligand of PPAR alpha, significantly reduces the mortality associated with influenza infections in mice. The inflammation-modulating abilities of these natural agents should be considered in light of what is now known about the mechanisms of fatal influenza, and tested as potential candidates for influenza treatments in their own right, or as adjunct treatments to antivirals.

Systemic infections of humans and birds with highly pathogenic avian influenza A viruses of the H5N1 subtype are characterized by inner bleedings and a massive overproduction of cytokines known as cytokine storm. Growing evidence supports the role of endothelial cells in these processes. The aim of this study was to elucidate determinants of this strong response in endothelial cells with a focus on the transcription factor NF-kappaB. This factor is known as a major regulator of inflammatory response; however, its role in influenza virus replication and virus-induced immune responses is controversially discussed. By global mRNA profiling of infected cells in the presence or absence of a dominant negative mutant of IkappaB kinase 2 that specifically blocks the pathway, we could show that almost all H5N1 virus-induced genes depend on functional NF-kappaB signaling. In particular, activation of NF-kappaB is a bottleneck for the expression of IFN-beta and thus influences the expression of IFN-dependent genes indirectly in the primary innate immune response against H5N1 influenza virus. Control experiments with a low pathogenic influenza strain revealed a much weaker and less NF-kappaB-dependent host cell response.

The acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) are part of a devastating syndrome characterized by acute onset, hypoxemia, and bilateral infiltrates on chest x-rays. ALI/ARDS is the response of the lung to a local or systemic aggression, resulting in local inflammation and coagulation disorders, which lead to increased inflammatory pulmonary edema. ARDS is a major cause of morbidity, death, and cost in intensive care units. The most common cause is sepsis. We present a case of ARDS secondary to infection with the influenza A (H1N1) virus. The influenza A (H1N1) virus caused a global pandemia 91 years ago, with sporadic outbreaks afterward. The new influenza A pandemia was transmitted from swine to humans. Infection by the influenza A (H1N1) virus can cause severe respiratory illness, the acute respiratory distress syndrome, and secondary infections among healthcare workers.

This flu season, health care providers must be prepared to treat patients who have the seasonal flu and also those who have contracted a novel strain of the H1N1 influenza virus. Although H1N1 flu is sometimes incorrectly called "swine flu," the virus is transmitted from person to person; it cannot be contracted from pigs or from eating pork products. Symptoms of the H1N1 flu include fever, chills, nausea, vomiting, body aches, lethargy, and fatigue, which usually appear in rapid succession. People at high risk include children, pregnant women, and those with certain medical conditions. The most common cause of death from the virus is respiratory failure, but other causes of mortality include sepsis, dehydration, and electrolyte imbalance. The first line of defense against H1N1 flu is vaccination. Treatment includes use of antiemetics, antipyretics, and respiratory support.

BACKGROUND. Given the apparent high mortality associated with the novel swine-origin influenza A/H1N1 virus (S-OIV) in Mexico, we aimed to study the cytokine profiles induced by S-OIV and the effect of immunomodulators. METHODS. We assayed cytokines and their messenger RNA (mRNA) levels in culture supernatants of human macrophages infected with H5N1, S-OIV California/04/2009 (S-OIV-CA), S-OIV Hong Kong/415742 (S-OIV-HK), or seasonal H1N1 with or without celecoxib and mesalazine. RESULTS. Among the 12 cytokines showing detectable levels, levels of 8 proinflammatory cytokines (interleukin [IL] 2R, IL-6, interferon [IFN] alpha, macrophage inflammatory protein [MIP] alpha, MIP-1beta, IFN-induced protein 10, regulated on activation, normal T cell expressed and secreted [RANTES], and monocyte chemotactic protein [MCP] 1) were higher in cells infected by H5N1 but similar among cells infected with H1N1, S-OIV-CA, or S-OIV-HK. The levels of the other 4 cytokines were similar for H5N1, H1N1, S-OIV-CA and S-OIV-HK. Among the 8 cytokines induced by H5N1, 6 were suppressed by celecoxib and mesalazine. The mRNA levels of tumor necrosis factor alpha, IFN-gamma, IL-6, and MCP-1 induced by H5N1 were higher than the levels of other cytokines at 12 and/or 24 h. CONCLUSIONS. No major cytokine storm, as seen in H5N1 infection, is associated with S-OIV infection of cell lines. The mainstay of treatment for uncomplicated S-OIV infections should be antiviral agents without immunomodulators. For individual S-OIV-infected patients with severe primary viral pneumonia, severe sepsis, and multiorgan failure, immunomodulators may be considered as an adjunctive therapy in clinical trials.

Influenza is an uncommon illness among premature infants in developed modern neonatal intensive care units (NICUs), but if infants do manifest symptoms of this significant illness, they commonly present with an abrupt onset, with temperature instability and upper respiratory tract involvement and, commonly, clinical features similar to bacterial sepsis. Additionally, frequent manifestations include bronchiolitis and pneumonia. Influenza infection in premature infants is likely a result of reduced levels of passively transferred protective maternal antibodies. Timely supportive therapy, antiviral agents, and isolation of affected infants to prevent spread of infection may be sufficient protective measures in the NICU. We report a case of a 50-day-old very low-birth-weight premature infant with novel A/H1N1 influenza virus (swine flu). There were no obvious epidemiological conditions in the NICU among patients and staff. The unique presenting symptom was apnea, which required respiratory support by nasal intermittent positive pressure ventilation. Due to the current pandemic, neonatologists should be aware of possible infection of neonates with novel A/H1N1 influenza virus.

Streptococcus pneumoniae (the pneumococcus) kills approximately 1.6 million people annually. Pneumococcal infections predominantly manifest as pneumonia, sepsis, meningitis, and otitis media. S. pneumoniae is also a member of the normal nasopharyngeal flora, colonizing up to 80% of children. Infection with influenza A virus (IAV) has been associated with both pneumococcal disease and transmission. However, to date no animal model has been available to investigate the role of IAV in the spread of S. pneumoniae. Here we investigate pneumococcal-influenza synergism with a particular focus on the role of IAV on pneumococcal transmission. Infant mice were colonized with S. pneumoniae and subsequently infected with IAV 3 d later. Using this novel model we show increased pneumococcal colonization and disease in the presence of IAV. Notably, in vivo imaging showed that IAV was essential for the transmission of S. pneumoniae from colonized ("index") mice to their naive cohoused littermates ("contacts"). Transmission occurred only when all mice were infected with IAV and was prevented when an IAV-neutralizing antibody was used to inhibit IAV replication in either index mice or contact mice. Together, these data provide novel insights into pneumococcal-influenza synergism and may indicate a previously unappreciated role of IAV in the spread of S. pneumoniae.

The innate immune system provides a first line of defense against invading pathogens by releasing multiple inflammatory cytokines, such as interleukin-1beta and tumor necrosis factor-alpha, which directly combat the infectious agent and recruit additional immune responses. This exuberant cytokine release paradoxically injures the host by triggering leakage from capillaries, tissue edema, organ failure, and shock. Current medical therapies target individual pathogens with antimicrobial agents or directly either blunt or boost the host's immune system. We explored a third approach: activating with the soluble ligand Slit an endothelium-specific, Robo4-dependent signaling pathway that strengthens the vascular barrier, diminishing deleterious aspects of the host's response to the pathogen-induced cytokine storm. This approach reduced vascular permeability in the lung and other organs and increased survival in animal models of bacterial endotoxin exposure, polymicrobial sepsis, and H5N1 influenza. Thus, enhancing the resilience of the host vascular system to the host's innate immune response may provide a therapeutic strategy for treating multiple infectious agents.

Evidence from previous influenza pandemics, epidemic seasonal influenza and, most recently, pandemic influenza A (H1N1) demonstrates that pregnant women and their offspring are at an increased risk for influenza-related complications. Influenza infections in pregnancy have been associated with adverse maternal and neonatal outcomes, including preterm labor and delivery, respiratory hospitalization, pneumonia, adult respiratory distress syndrome, overwhelming sepsis and death. The influenza vaccine has been repeatedly demonstrated to be both safe and effective in pregnant women and the potential for passive transfer of protective antibodies to the neonate adds to the cumulative benefits of maternal influenza immunization. Despite the potential benefit of this vaccine during pregnancy, low vaccination rates in both the USA and in other industrialized countries have been disconcerting.
