Pediatr Infect Dis J 1990, 9: 333–339. Nonencapulated forms are designated as nontypeable Haemophilus influenzae (NTHi). There are two other important situations, which have potentially significant effects on the immune response to NTHi in the lung. 10.1136/thx.49.8.825. 10.1016/j.vaccine.2006.04.041, Shuto T, Xu H, Wang B, et al.

Microb Pathog 1989, 7: 225–235. This can result in airway inflammation and colonization particularly in chronic obstructive pulmonary disease. PubMed  Patients with milder infections are given oral antibiotics, including amoxicillin, cefaclor, erythromycin, or trimethoprim-sulfamethoxazole. statement and This bacterium is divided into typeable forms (such as type b) or nontypeable forms based on the presence or absence of a tough polysaccharide capsule. Cite this article. Exacerbations of COPD are frequently associated with combined viral and bacterial infection and the most common co-infection is the combination of rhinovirus and H. influenzae, which is also associated with increased severity of exacerbations [51, 52]. McGraw Hill, New York; 2001:939–942. A murine model of COPD has recently demonstrated that the addition of an NTHi lysate induces the formation of lymphoid follicles in the bronchi [63]. Approximately 20 % of infants are colonized in the first year of life and this rises progressively over time [5]. Moxon ER, Deich RA, Connelly C: Cloning of chromosomal DNA from Haemophilus influenzae. Am J Respir Crit Care Med 2001, 164: 2114–2119. Laboratory tests can be used to confirm the diagnosis of hemophilus infections. The illness is generally less fulminant than that with S. pneumoniae and commonly occurs in patients with underlying lung disease (particularly COPD). Sethi S, Evans N, Grant BJ, Murphy TF: New strains of bacteria and exacerbations of chronic obstructive pulmonary disease. The adhesins are a common and important factor to facilitate epithelial attachment. Cell 1993, 73: 1187–1196.

This site is intended for use by US Healthcare Professionals only. Cystic Fibrosis Transmembrane Conductance Regulator, https://creativecommons.org/licenses/by/2.0. Exacerbations of COPD from NTHi can arise from the acquisition of new strains [9](presumably from the upper airway) or from existing colonizing strains. Manage cookies/Do not sell my data we use in the preference centre. The adaptive immune response develops after the innate response and is particularly important in chronic infectious disease. Haemophilus influenzae (Hi) disease is caused by a bacterial infection. There is preliminary evidence from laboratory studies that rhinovirus may interact with NTHi. Innate immunity serves as the first-line of defense against infection and is comprised of both structural and cellular defenses. Computed tomography (CT) scan of a subject with severe lower lobe bronchiectasis and recurrent isolation of N Engl J Med 2002, 347: 465–471. Thorax 2008, 63: 519–525. Gaschler GJ, Skrtic M, Zavitz CC, et al. The three cardinal clinical manifestations of exacerbation include increased sputum volume, increased sputum purulence (color), and increased dyspnea compared to baseline symptoms. Key mechanisms are summarized in Table 1. A major cause of death in epidemic viral influenza is secondary bacterial lung infection. References: 1.

Therefore in the later stages of CF NTHi may still be important in parenchymal lung infection. NTHi is classified into biotypes using indole, urease and ornithine decarboxylase. 10.1074/jbc.M107484200. Proc Natl Acad Sci U S A 1996, 93: 11913–11918. This has been described in the context of nontypeable strains. NTHi is present in the nasopharynx of most healthy adults but only causes clinical disease in a minority of subjects it infects. The vaccine to type B encapsulated H. influenzae induces humoral immunity to the capsule and has been highly effective in reducing the incidence of disease from this pathogen. Chest 2006, 129: 317–324. Improvement in patient outcome will be dependent on a better understanding of the pathogenesis and host immune response to this bacterium. NTHi is prominent in the early stages of CF; in later stages other bacterium such as Pseudomonas are predominant. 10.1136/thorax.57.9.759, Moghaddam SJ, Clement CG, De la Garza MM, et al. Nearly all NTHi strains express one of these IgA proteases which are highly effective in inhibiting IgA.
