Levels of cytokines, interleukin (IL)–1α, IL-1β, tumor necrosis factor (TNF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) were investigated in samples of the middle ear effusions (MEEs) from 144 ears with otitis media with effusion (OME) by enzyme-linked immunosorbent assay, followed by cytologic analysis. Middle ear effusions of the acute purulent type contained a significantly higher concentration of cytokines compared with normal control sera (p < .001). Cytokines were observed at lower levels in MEE in adults than in children. Tests of children at the chronic stage of MEE showed higher levels of TNF than IL-1 and GM-CSF. Meanwhile, IL-1β showed significantly higher concentrations in acute purulent types than in serous and mucoid types (p < .01). In cytologic analysis, the mean level of IL-1β was significantly higher in the neutrophil-rich group than in other groups (p < .05). Cytokines possess several biologic properties, some of which are associated not only with acute otitis media but also with chronic otitis media. This study showed that cytokines, especially IL-1β, contribute to infiltration into the middle ear by inflammatory cells. This implies that the persistent presence of cytokines in MEE could be a factor in prolonged OME.

GOALS, DEFINITIONS, AND CLASSIFICATION OF OTITIS MEDIA —Charles D. Bluestone, MD The goal of this Workshop was to assess current knowledge concerning the effects of otitis media on the child. Experts in pediatrics, infectious disease, otolaryngology, audiology, speech, linguistics, and psychology met in Chicago on Aug 25, 1982 to participate in this Workshop. A summary of the discussions is presented here. Otitis media is broadly defined as an inflammation of the middle ear without reference to etiology or pathogenesis.1 Otitis media with effusion is an inflammation of the middle ear in which a collection of liquid (i.e., middle ear effusion) is present in the middle ear space (no perforation of the tympanic membrane is present). Atelectasis of the tympanic membrane, which may or may not be associated with otitis media, is defined as either collapse or retraction of the tympanic membrane. Acute otitis media implies a rapid and short onset of signs and symptoms lasting approximately 3 weeks. From 3 weeks to 3 months, the process may be resolving or subacute. If middle ear effusion persists beyond 3 months, the condition is classified as chronic otitis media with effusion. Many terms have been used for acute otitis media, such as "suppurative," "purulent," or "bacterial" otitis media; however, a "serous" effusion may also have an acute onset. Otitis media with effusion unaccompanied by signs and symptoms of acute inflammation has also had a plethora of other names: "serous," "secretory," "nonsuppurative," and "glue ear" have been the most commonly used.

Definitions Acute otitis media with effusion (AOME) is a clinically identifiable, suppurative infection of the middle ear. The infection has a relatively sudden onset and short duration. It denotes inflammation of the mucoperiosteal lining of the middle ear. The inflamed tympanic membrane (TM) is bulging, opacified, or both. The condition chronic otitis media is poorly defined, but it may be categorized into two clinical entities for simplification: chronic otitis media with effusion (COME) and chronic suppurative otitis media (CSOM). COME, also known as serous or non-suppurative otitis media, is characterized by the presence of a middle ear effusion (MEE) behind an intact TM that persists for more than 2 to 3 months. It may be asymptomatic except for hearing loss. There generally are no acute clinical signs or symptoms, and the TM is not red or bulging. CSOM is characterized by chronic perforation of the TM, with purulent discharge, for a prolonged period of time, usually more than 6 weeks. There generally is an insidious clinical onset. Either COME or CSOM may follow AOME. Epidemiology Otitis media is one of the most frequent causes for physician visits by children. Approximately 25% of such visits during the first year of life are for middle ear disease; this increases to 40% for children 4 to 5 years of age.

A Prospective Study

Otitis media with effusion is a common cause of diminished hearing in children younger than 12 years. Hypertrophy of adenoids is one of the commonest etiologies of this condition. It has been mentioned that with increased size of the adenoid tissue, the more likely the incidence of fluid in the middle ear. The aim of this study was to find whether there is a correlation between adenoid size, tympanometric findings, and type of fluid in the middle ear irrespective of disease duration. This is a prospective study done on 100 pediatric patients (12 years and less) presented with chronic otitis media with effusion (COME) and adenoid hypertrophy from July 2015 till July 2017. Cases with tympanometry evidence of COME (B, Cs) and adenoid hypertrophy seen by nasal endoscopy were included. Adenoid size was graded and correlated with the type of tympanometry and type of fluid in the middle ear. Sixty male children and 40 female children were involved. Age ranged from 3 to 12 years with a mean of 7.19 ± 2.489 years. Highly significant relation existed between grade 4 adenoid hypertrophy and mucoid nature of middle ear fluid ( P value = .000). There is a highly significant relation between adenoid hypertrophy grade Ⅳ and type B tympanometry. There is a highly significant relation between adenoid size and nature of middle ear fluid irrespective of the duration of complaints, where grade Ⅳ adenoid hypertrophy showed more increase in middle ear effusion viscosity making adenoid size a very important predictor for the tympanometry type and the nature of the fluid in the middle ear.

Increased Risk

Children younger than 7 years are at increased risk of otitis media because of their immature immune systems and poorly functioning eustachian tubes that normally ventilate the middle ear space and equalize pressure with the external environment. More than 80% of children have at least one episode of acute otitis media (AOM) before the age of 3 years and 40% experience six or more recurrences by the time they are 7 years old.1 By the age of 3 years, approximately 7% of children undergo surgery for tympanostomy tube insertion for a range of otitis media issues, most commonly for chronic otitis media with effusion (OME), recurrent acute AOM, and acute otitis media that persists despite antibiotic therapy.2 However, tympanostomy tube insertion is associated with risks and remains a controversial practice especially in children with OME of less than three months’ duration and in children with recurrent AOM. Adverse effects associated with tympanostomy tube insertion include those associated with anaesthesia and its complications (laryngospasm, bronchospasm), as well as tube related sequelae such as recurrent (7%) or persistent (16–26%) otorrhoea, blockage of the tube lumen (7%), granulation tissue (4%), premature extrusion of the tube (4%), tympanostomy tube displacement into the middle ear (0.5%) and persistent perforation of the tympanic membrane (1%–6%).3 This article offers guidance for family practitioners wishing to optimize health outcomes in children potentially requiring tympanostomy tube placement.

Chemical Mediators

Otitis media has a complex multifactorial pathogenesis, and the middle ear inflammatory response is typified by the accumulation of cellular and chemical mediators in middle ear effusion. However, specific biochemical and immunochemical factors that may be responsible for the severity or chronicity of otitis media have not been identified. Identification of factors involved in chronicity appears to be an essential step in the treatment and ultimate prevention of chronic otitis media. We analyzed 70 effusion samples from patients 1 to 10 years of age who had chronic otitis media with effusion for two cytokines (interleukrn-1β and tumor necrosis factor α) and total collagenase. The highest concentrations of all three inflammatory mediators were found in purulent otitis media, and concentrations were higher in younger than in older patients. Mediator concentrations were similar in samples obtained from patients having their first myringotomy for otitis media with effusion and in those who had had multiple previous myringotomies. The multiresponse star, which incorporates several biochemical parameters in one graphic illustration, may best characterize the complex nature of middle ear inflammation.

ABSTRACT The gram-negative bacterium nontypeable Haemophilus influenzae (NTHI) is the predominant pathogen in chronic otitis media with effusion and, with Streptococcus pneumoniae and Moraxella catarrhalis, is a causative agent of acute otitis media. To identify potential virulence determinants, bacterial gene expression was monitored by differential fluorescence induction during early disease progression in one specific anatomical niche of a chinchilla model of NTHI-induced otitis media. Genomic DNA fragments from NTHI strain 86-028NP were cloned upstream of the promoterless gfpmut3 gene. NTHI strain 86-028NP served as the host for the promoter trap library. Pools of 2,000 transformants were inoculated into the left and right middle ear cavities of chinchillas. Middle ear effusions were recovered by epitympanic tap at 24 and 48 h, and clones containing promoter elements that were induced in vivo and producing green fluorescent protein were isolated by two-color fluorescence-activated cell sorting. Insert DNA was sequenced and compared to the complete genome sequence of H. influenzae strain Rd. In a screen of 16,000 clones, we have isolated 44 clones that contain unique gene fragments encoding biosynthetic enzymes, metabolic and regulatory proteins, and hypothetical proteins of unknown function. An additional eight clones contain gene fragments unique to our NTHI isolate. Using quantitative reverse transcription-PCR, we have confirmed that 26 clones demonstrated increased gene expression in vivo relative to expression in vitro. These data provide insight into the response of NTHI bacteria as they sense and respond to the middle ear microenvironment during early events of otitis media.
