Regulation of interferon-gamma during innate and adaptive immune responses. Then there are individuals who have infants at home or visit long-term care facilities who are at a greater risk or of transmitting the virus to others, Temte explains. Global trends in emerging infectious diseases. Webster R. G., Bean W. J., Gorman O. T., Chambers T. M., Kawaoka Y. Bacterial coinfection is associated with severity of avian influenza A (H7N9), and procalcitonin is a useful marker for early diagnosis. HHS Vulnerability Disclosure, Help The first conclusive evidence that influenza virus could cause pneumonia came during the 1958 to 1959 pandemic. Epidemiology, diagnosis, and antimicrobial treatment of acute bacterial meningitis. A. Sore throat, fever, cough must be the flu, right? Accessibility Prodromal stage 3. This is possibly a reflection of increased antibiotic use and increased antibiotic resistance. As influenza infection develops the virus causes cell damage and death within the hosts airways and up-regulates the production of toxins, causing further destruction. Unfortunately, theres no magic cure-all and no secret to preventing the spread of illness. Before For older adults and people with a . , The pneumonias and other infections of the respiratory tract accompanying influenza and measles. As the threat from influenza is ever changing, we need to ensure we know what strains are circulating, which could cause issue and how they interact with other potential pathogens. Kollef M. H., Shorr A., Tabak Y. P., Gupta V., Liu L. Z., Johannes R. S. (2005). Effect of virus infection on the inflammatory response. Influenza complicated by bacterial pneumonia is an effective model to study host defense during pulmonary superinfection due to its clinical relevance. Of these children, 47% had no specific clinical signs or symptoms suggesting pneumonia. One group of rats were naive and the other had previously been dosed with influenza. Otitis media and sinusitis in children. (2005). Hakansson A., Kidd A., Wadell G., Sabharwal H., Svanborg C. (1994). The immunology of influenza virus-associated bacterial pneumonia. Youzbashi E., Marschall M., Chaloupka I., Meier-Ewert H. (1996). Sequential bacterial infection normally occurs within a 7-day period of the viral infection. Case study: Complicated influenza pneumonia - PMC - National Center for Identifying the interaction between influenza and pneumococcal pneumonia using incidence data. In response to viral infection, host inflammatory responses may cause an up-regulation in the expression of host receptor molecules and other molecules that bacteria can use as a receptors (Hakansson et al., 1994; Peltola and McCullers, 2004). (2009) examined nasopharyngeal swab samples from almost 200 cases of pandemic influenza. Respiratory tract infections, however, continue to be a major cause of morbidity and mortality worldwide (Lozano et al., 2012; Morse et al., 2012; Zumla et al., 2014). IL-17 is important in the clearance of S. aureus by neutrophils (Archer et al., 2013). Rice T. W., Rubinson L., Uyeki T. M., Vaughn F. L., John B. S. pneumoniae is a Gram-positive diplococci and is the most common cause of community-acquired pneumonia and invasive disease, i.e., sepsis and meningitis worldwide, as well as less severe acute disease such as otitis media (Bridy-Pappas et al., 2005; McCullers et al., 2010). et al., 2010; McCullers et al., 2010; Smith and McCullers, 2014). Legionella pneumophila (Rizzo et al., 2010), Streptococcus pyogenes (Chertow and Memoli, 2013), Neisseria meningitidis, Moraxella catarrhalis, S. pneumoniae, H. influenzae, S. aureus (Dela Cruz and Wunderink, 2017), Pseudomonas aeruginosa as well as a number of other Streptococcus and Staphylococcus spp. Hament J.-M., Kimpen J. L. L., Fleer A., Wolfs T. F. W. (1999). Of course it is known that there is a positive association between the colonization of H. influenzae and S. pneumoniae, and colonization is a prerequisite for disease, so the presence of such co-infection fits with current knowledge (Jacoby et al., 2007; Abdullahi et al., 2008). Dormitzer P. R., Galli G., Castellino F., Golding H., Khurana S., Del Giudice G., et al. A., Woolhouse M., Parrish C. R., Carroll D., Karesh W. B., et al. Robinson et al. The highly invasive pneumococcal serotype 4 caused pneumonia in 58% of mice and bacteraemia in 21% in a single infection model. Ordinarily only young children and the elderly are the age groups most at risk from influenza, showing how distinctive pandemic strains can be (Potter, 2001). Plotkowski et al. SARS-CoV-2 is with us for the long haul. Respiratory viruses predisposing to bacterial infections: role of neuraminidase. This guideline is designed to provide guidance for pneumonia in most children. Nayak D. P., Balogun R. A., Yamada H., Zhou Z. H., Barman S. (2009). (2010). Multiprotein inflammasomes are responsible for IL-1 production in response to infection and drive tissue inflammation. Those H. influenzae that lack a capsule, denoted non-typeable H. influenzae (NTHi), remain a significant cause of bacterial meningitis, otitis media and exacerbations of chronic lung disease such as COPD worldwide (Langereis and de Jonge, 2015). Moraxella catarrhalis is a bacteria of increasing importance being now acknowledged as the third most common cause of otitis media (OM), after S. pneumoniae and H. influenzae (Bluestone, 1986; Faden et al., 1994; Kilpi et al., 2001; Dupont et al., 2010) and the second most common cause of exacerbations in COPD, accounting for up to 4 million exacerbations per year in the United States alone (Murphy et al., 2005). Complicated pneumonias were rare, and mortality was low (0.7% . In the setting of an influenza epidemic or pandemic bacterial co/secondary infection can have devastating consequences, particularly in at-risk groups such as the immunocompromised/immunosuppressed. A number of viral infections (including infection from influenza virus, respiratory syncytial virus, parainfluenza virus and human metapneumovirus) can be complicated by co/secondary infection by a variety of bacteria including Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. (2004). Jackson C., Mangtani P., Hawker J., Olowokure B., Vynnycky E. (2014). The other author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Rizzo C., Caporali M. G., Rota M. C. (2010). Pneumonia - Diagnosis and treatment - Mayo Clinic (2016). Fatal outcome of human influenza A (H5N1) is associated with high viral load and hypercytokinemia. Various studies have shown the impact when H. influenzae co/secondarily infects with influenza, and some suggest a level of synergism. Of course viral infection and/or interference with host processes can cause and direct the pathway of cell death, as is the case for necrosis. Influenza cytotoxins for example causes necrosis of host cells (Conenello and Palese, 2007; Iverson et al., 2011). (2016). But some people with HIV still develop OIs because Feder H. M., Jr., Garibaldi R. A. Pneumococcal vaccination has shown to ameliorate the risk of secondary bacterial pneumonia. Pandemic influenza in 1957; review of international spread of new Asian strain. The https:// ensures that you are connecting to the Those infected with high doses of influenza died within 47 days; however, all mice infected with a high dose of influenza and then a high dose S. aureus died within 2 days of bacterial exposure, showing how death can be accelerated by co-infection. Yang M., Gao H., Chen J., Xu X., Tang L., Yang Y., et al. Although reported less, influenza B has also been associated with severe bacterial co/secondary infection (Finelli et al., 2008; Aebi et al., 2010). Complications of Viral Influenza - PMC - National Center for Donations to UW Health are managed by the University of Wisconsin Foundation, a publicly supported charitable organization under 501(c)(3) of the Internal Revenue Code. Evolution and ecology of influenza A viruses. It is suggested that war time efforts meant that influenza easily spread through military camps, allowing the 2040 years old age range to be more at risk than usual. Haemophilus influenzae is another bacteria commonly found to co/secondarily infect viral infection, and has been associated with the complication of disease during influenza pandemics (Abrahams et al., 1919; Spooner et al., 1919; Brundage, 2006; Palacios et al., 2009). Of 129 adults diagnosed with pandemic influenza, pneumonia was established in 16%, of which 40% of these cases (6% of all 129 influenza cases) were fatal. Progeny virions bud from the host cell, using the host cell membrane as a viral envelope, and go on to infect neighboring host cells (Nayak et al., 2009). Robertson L., Caley J. P., Moore J. (1989). Furthermore infection with some influenza subtypes, for instance H1N1 and H5N1, typically result in lymphopenia, a state of abnormally low levels of lymphocytes, which has been associated with higher viral load. Influenza pneumonia - PubMed Influenza-associated pediatric mortality in the United States: increase of. Alternatively, we must consider that as M. catarrhalis was not considered a pathogen it was therefore missed or not commented upon prior to the 1980s. The role of viral, host, and secondary bacterial factors in influenza pathogenesis. Additionally, a 2020 study that looked at more than 80,000 U.S. adults hospitalized with flu over eight flu seasons (2010-11 through 2017-18) found that sudden, serious heart complications occurred in one out of every eight patients (~12% of patients). Two rare cases of Chinese female patients with influenza B virus infection complicated with both fulminant pneumonia and septicemia caused by Panton-Valentine leukocidin(PVL) positive methicillin-sensitive Staphylococcus aureus (MASS) were reported for the first time in China through next-generation sequencing (NGS). A. Influenza infection has been shown to increase the adherence of S. aureus (as well as H. influenzae and S. pneumoniae) to host pharyngeal cells (Fainstein et al., 1980). Co/secondary bacterial infection, as the name suggests, is a bacterial infection that occurs during or after an infection from another pathogen, commonly viruses. The significance of nongonococcal, nonmeningococcal. Predictive clinicopathological features derived from systematic autopsy examination of patients who died with A/H1N1 influenza infection in the UK 2009-10 pandemic. AB - Objective: To determine the impact of influenza coinfection on outcomes for children with complicated pneumonia. Co-infection also results in a synergistic increase in type II IFN (IFN) when compared to individual infection of influenza or S. pneumoniae, CXCL10 (aka IFN-induced protein 10/IP-10) is secreted in response. (2012). As mentioned previously, HA mediates virion binding to the host cell via sialic acid receptors. (2016). "By very early, we mean starting the medication within 48 hours of the first symptoms of influenza," he says. Overview of community-acquired pneumonia in adults - UpToDate The current public health impact of S. pneumoniae infection is reduced by vaccine policies, with, for example, PCV-13 and PPV-23 being used for children and adults, respectively, in the United Kingdom (Pittet and Posfay-Barbe, 2012). Mortality rose from 0% during individual infection to 63% during co-infection (Sharma-Chawla et al., 2016). Tong S. Y., Davis J. S., Eichenberger E., Holland T. L., Fowler V. G., Jr., et al. In another study of vulnerable and critically ill children in a pediatric intensive care unit in the United States, 51% of those with influenza infection had bacterial co/secondary infection. Is it Influenza or an Influenza-Like Illness? - UW Health (2005). EnglishEspaol (Spanish)Hmoob (Hmong) (Chinese)Deutsch (German) (Arabic) (Russian) (Korean)Ting Vit (Vietnamese)Deitsch (Pennsylvania Dutch) (Lao)Franais (French)Polski (Polish) (Hindi)Shqip (Albanian)Tagalog (Tagalog Filipino), who researches influenza and influenza-like viruses in local communities, Language Access: Notice of Nondiscrimination. A majority showed evidence of influenza A infection; 27% of those had co/secondary infection of S. aureus (which had a 47% death rate), 15% S. pneumoniae and 4% H. influenzae, although this is likely to be an underestimation as many patients had already started taking antibiotics (Robertson et al., 1958). Nosocomial pneumonia refers to an acute infection of the pulmonary parenchyma acquired in hospital settings and encompasses both hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP). "Unfortunately theres a lot of mis-use of words out there, which can lead to confusion," he says. Oxford J. S., Sefton A., Jackson R., Innes W., Daniels R. S., Johnson N. P. (2002). (1958). Nguyen T., Kyle U. G., Jaimon N., Tcharmtchi M. H., Coss-Bu J. Details of significant influenza pandemics since the late 1800s. More cases of pneumonia and bacteraemia were observed in mice infected with both influenza A and S. pneumoniae than in mice infected with these pathogens individually. A person with pneumonia may have trouble breathing and have a cough and fever. Influenza, or flu, is an unpleasant affair with fever, cough, as well as head and body ache. A point of concern is that almost half of the S. aureus were MRSA, and therefore inherently resistant to multiple antibiotics. H. influenzae was found in 52%, S. pneumoniae was found in 31% and S. aureus in 18% of samples. However, S. pneumoniae, H. influenzae, and S. aureus are the most commonly reported bacteria associated with co/secondary infections during influenza pandemics since the late 1800s. As a library, NLM provides access to scientific literature. (2012). Blue The origin of the 1918 Spanish is still unclear, although various papers suggest the United States (New York) or France as the origin; yellow China the origin of the 1957 Asian flu pandemic; Hong Kong, the origin of the 1968 Hong Kong pandemic; red Russia, the origin of the 1889 and 1977 Russian flu pandemics; green Mexico, the origin of the 2009 Swine flu pandemic. (1975) inoculated squirrel monkeys with either influenza A, S. pneumoniae or influenza A and S. pneumoniae. CDC and the Healthcare Infection Control Practices Advisory Committee developed these recommendations. (1977), who dosed two groups of rats intranasally with H. influenzae with the intention of giving them meningitis. Wertheim H. F., Melles D. C., Vos M. C., van Leeuwen W., van Belkum A., Verbrugh H. A., et al. (2005). Pneumonia - What Is Pneumonia? | NHLBI, NIH In the years between 1933 and 1957 there were nine influenza A (H1N1) epidemics and five influenza B epidemics. PDF Antibiotic Treatment Guidelines for Pneumonia in Pediatric Patients Pre-1983 laboratories would only undertake bacterial culture, however, in 2009 more sensitive methodology, i.e., PCR were available and commonly used in laboratories worldwide. (2013). Influenza vaccines: challenges and solutions. Binding is followed by endocytosis and the movement of the virion into the host cell within an endosome (Samji, 2009). Kleinerman E. S., Daniels C. A., Polisson R. P., Snyderman R. (1976). (2010). (2017). Madhi S. A., Adrian P., Kuwanda L., Cutland C., Albrich W. C., Klugman K. P. (2007). Iverson A. R., Boyd K. L., McAuley J. L., Plano L. R., Hart M. E., McCullers J. official website and that any information you provide is encrypted In a retrospective study of 50 patients who were infected during pandemic influenza, 28% showed co/secondary bacterial infection (Dhanoa et al., 2011). Within a 1-month period in 1918 at the military Camp Devens, a quarter of all troops were diagnosed with influenza. Effect of experimental influenza A virus infection on isolation of. To be truly effective the NA must be complementary and share the same receptor specificity as HA, so if the viral HA binds to 2-3 sialic acid then the NA should hydrolyse 2-3 sialic acid (Baum and Paulson, 1991). Dupont D., Mahjoub-Messai F., Francois M., Doit C., Mariani-Kurkdjian P., Bidet P., et al. The site is secure. Influenza promotes pneumococcal growth during coinfection by providing host sialylated substrates as a nutrient source. Fedson D. S., Wajda A., Nicol J. P., Hammond G. W., Kaiser D. L., Roos L. L. (1993). Pneumonia is a serious infection or inflammation of the lungs. de Jong M. D., Simmons C. P., Thanh T. T., Hien V. M., Smith G. J., Chau T. N., et al. The 2009 H1N1 influenza outbreak in its historical context. Community-acquired pneumonia (CAP) refers to an acute infection of the pulmonary parenchyma acquired outside of the hospital. Influenza infection also results in increased mucus production, further increasing the amount of metabolite available for S. pneumoniae. Calix J. J., Porambo R. J., Brady A. M., Larson T. R., Yother J., Abeygunwardana C., et al. 8600 Rockville Pike A., Gerin J. L., Schulman J. L., Kilbourne E. D. (1974). Influenza tends to last within a community for eight to nine weeks meaning approximately 90 percent of cases will occur during that time frame. Influenza virus neuraminidase contributes to secondary bacterial pneumonia. Increased lung damage and bacterial density has also been shown (DeLeo and Musser, 2010; Lee M.H. It is now commonly accepted that co-infection results in more severe morbidity and poorer clinical outcome than infection of influenza or H. influenzae alone. The 1918 influenza pandemic was a result of influenza strain A (H1N1). Pai R., Gertz R. E., Whitney C. G., Beall B. Influenza coinfection and outcomes in children with complicated pneumonia Influenza is a communicable viral disease that affects the upper respiratory tract, including upper and lower respiratory passages. Examples include Coxiella burnetii which typically causes Q fever in cattle, sheep and goats but can also infect humans (Eldin et al., 2017), the plague causing Yersinia pestis, infamously transmitted to humans by rats via a flea vector (Yang et al., 2016b), human immunodeficiency virus (HIV) which originated in non-human primates before spreading into the human population (Rupp et al., 2016) and of course the most common example, influenza, which circulates within and between swine, avian and human hosts (amongst others). Pandemics are generally viral in cause. Pneumonia (for Teens) - Nemours KidsHealth This pandemic affected 4050% of people worldwide. S. pneumoniae again caused minor illness with a 100% survival rate. More virulent pneumococcal serotypes caused a greater burden of disease in both the co-infected mice and those infected with S. pneumoniae alone. (2012). Influenza and other respiratory viruses are commonly identified in patients with community-acquired pneumonia, hospital-acquired pneumonia, and in immunocompromised patients with pneumonia. Weinberger D. M., Simonsen L., Jordan R., Steiner C., Miller M., Viboud C. (2012). There are three types of influenza virus, types A, B, and C, each differing in host range and pathogenicity (Taubenberger and Morens, 2008). Maintaining a polite distance from people roughly six feet can help, using a face mask while in public, and, of course, hand washing, staying home when sick, covering coughs and most important of all - getting vaccinated. Viral infection aids bacterial infection in a number of ways, including unveiling/providing more sites for adhesion, impairing immune responses and causing cell and tissue destruction allowing for the spread of bacteria and development of invasive infection. (1992). Influenza virus infection and bacterial clearance in young adult and aged mice. Although most symptoms ease in a few days or weeks, the feeling of tiredness can persist for a month or more. These factors can result in divergence of surface antigens, such as haemagglutinin (HA) and neuraminidase (NA), producing strains not recognized by the human immune system and not covered by extant vaccines (Holland et al., 1982; Webster et al., 1992; Chen and Holmes, 2006; Hampson and Mackenzie, 2006; Jones et al., 2008; Taubenberger and Morens, 2008; Dormitzer et al., 2011; Morse et al., 2012). When it comes to treatments, alleviating the symptoms of influenza, COVID-19 or flu-like illness through time-worn techniques good hydration, hot showers for congestion, over the counter medicines like ibuprofen for body aches can help. Influenza virus morphogenesis and budding. (2005). Scott M. J., Hoth J. J., Stagner M. K., Gardner S. A., Peyton J. C., Cheadle W. G. (2004). Connect HW: Chapter 13 Flashcards | Quizlet (2012). Of these, 41% were shown to have complications associated with secondary bacterial infection, most commonly (25% of cases) due to S. pneumoniae (Lucas, 2010). People who have community-acquired pneumonia usually can be treated at home with medication. Kash J. C., Walters K. A., Davis A. S., Sandouk A., Schwartzman L. M., Jagger B. W., et al. Bacterial infection is then able to worsen clinical outcome and the severity of disease. Of 129 adults diagnosed with pandemic influenza, pneumonia was established in 16%, of which 40% of these cases (6% of all 129 influenza cases) were fatal. 1Infectious Disease Epidemiology Group, Academic Unit of Clinical and Experimental Sciences, Faculty of Medicine, Institute for Life Sciences, University of Southampton, University Hospital Southampton Foundation NHS Trust, Southampton, United Kingdom, 2Global Health Research Institute, University of Southampton, Southampton, United Kingdom, 3NIHR Southampton Respiratory Biomedical Research Unit, Southampton, United Kingdom. CAP is a common and potentially serious illness [ 1-5 ]. We detected highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b virus in a domestic cat that lived near a duck farm infected by a closely related virus in France during December 2022. Bacteriology of acute otitis media in a cohort of Finnish children followed for the first two years of life. Interleukin-22 regulates antimicrobial peptide expression and keratinocyte differentiation to control, Respiratory infections caused by non-typeable. Type A has been isolated from humans, avian, swine, horses, mink, dogs, seals, and ferrets (Jakeman et al., 1994; Taubenberger and Morens, 2008; Parrish et al., 2015), whilst type B has been isolated from humans, seals (Osterhaus et al., 2000) and ferrets (Jakeman et al., 1994), and type C from humans (Matsuzaki et al., 2002), swine and dogs (Youzbashi et al., 1996). Your first thought is to code this as acute laryngitis, J04.0; however, this code falls in the J00-J06 range titled "Acute upper respiratory infections" and you see no evidence that this is an . Discovery of a new capsular serotype (6C) within serogroup 6 of. "The time of year we have our influenza vaccine clinics is often September, October and November," Temte explains. Primary Influenza Virus Pneumonia. Transmissibility and geographic spread of the 1889 influenza pandemic. Lee E. H., Wu C., Lee E. U., Stoute A., Hanson H., Cook H. A., et al. Inclusion in an NLM database does not imply endorsement of, or agreement with, Flu Complications: Pneumonia, Bronchitis, and More - Healthline Influenza is a major cause of epidemic and pandemic infection. 1. Necrosis and pyroptosis are pro-inflammatory due to their role in the release of cytokines. Biggerstaff M., Cauchemez S., Reed C., Gambhir M., Finelli L. (2014). Polymorphonuclear leukocyte dysfunction during influenza virus infection in chinchillas. In the United Kingdom, of the 457 fatalities 68 were autopsied. M. catarrhalis is a cause of pneumonia (Berg and Bartley, 1987; Hager et al., 1987; Marchant, 1990; Verduin et al., 2002) and invasive disease such as bacteraemia (Ioannidis et al., 1995) and meningitis (Newing and Christie, 1947), with bacteraemia being a common complication of pneumonia, particularly in adults (Collazos et al., 1992; Ioannidis et al., 1995). et al., 2010; Iverson et al., 2011). Wadowsky et al. (2011). While you should always contact your doctor if you have questions or concerns, Temte explains that there are a few things he looks at when trying to make a determination. When it is influenza, Temte says, there are medications that can be highly effective if used very early in the course of symptoms. Verduin C. M., Hol C., Fleer A., van Dijk H., van Belkum A. At any point and time there are approximately 10 million individuals in the U.S. who are on an immunosupressent drug. Indeed in 19161917 British, Australian, Canadian, and American armed forces in England and France experienced an epidemic of purulent bronchitis. (2010). A recent epidemic of acute respiratory infection at camp custer, mich: preliminary laboratory report. In mild cases of the flu, the virus enters your body via the nose or mouth and infects the upper respiratory tract: the nasal cavity, sinuses, throat, and larynx. Sanford B. SARS-CoV-2 can present with a very wide variety of symptoms including those suggestive of influenza.". (1995). Influenza infections and successive S. pneumoniae infections result is a time and dose dependent change in the host dendritic cells which produces enhanced inflammation. Robertson et al. Genetic analysis of the capsular biosynthetic locus from all 90 pneumococcal serotypes. Jin P., Kong F., Xiao M., Oftadeh S., Zhou F., Liu C., et al. Therefore HA and the availability of appropriate host proteases are determinants of infectivity (Steinhauer, 1999; Samji, 2009). Okamoto S., Kawabata S., Nakagawa I., Okuno Y., Goto T., Sano K., et al. The frequency of influenza and bacterial coinfection: a systematic review and meta-analysis. (2011). If COVID-19 is suspected, it is of critical importance to get tested, and if positive isolate yourself, work with public health for contact tracing, and obtain medical attention if symptomssuch are shortness of breathare significant.
