Tonsillitis is inflammation of the tonsils most commonly caused by a viral or bacterial infection whose symptoms include sore throat and fever. The overwhelming majority of patients recover completely with or without medication. In 40%, symptoms have resolved in three days and within one week in 85%, regardless of whether streptococcal infection (an important cause) is present or not.[1]

Symptoms
Common signs and symptoms include:[2][3][4][5]
- sore throat
- red, swollen tonsils
- pain when swallowing
- high temperature (fever)
- headache
- tiredness
- chills
- a general sense of feeling unwell (malaise)
- white pus-filled spots on the tonsils
- swollen lymph nodes (glands) in the neck
- pain in the ears or neck
Less common symptoms include:
- nausea
- stomach ache
- vomiting
- furry tongue
- bad breath (halitosis)
- voice changes
- difficulty opening the mouth
In cases of acute tonsillitis, the surface of the tonsil may be bright red and with visible white areas or streaks of pus.[6]
Tonsilloliths occur in up to 10% of the population frequently due to episodes of tonsillitis.[7]
Causes
The most common cause is viral infection and includes adenovirus, rhinovirus, influenza, coronavirus, and respiratory syncytial virus.[2][3][4][5] It can also be caused by Epstein-Barr virus, herpes simplex virus, cytomegalovirus, or HIV.[2][3][4][5] The second most common cause is bacterial infection of which the predominant is Group A β-hemolytic streptococcus (GABHS), which causes strep throat.[2][3][4][5] Less common bacterial causes include: Staphylococcus aureus (including methicillin resistant Staphylococcus aureus or MRSA ),[8]Streptococcus pneumoniae, Mycoplasma pneumoniae, Chlamydia pneumoniae, pertussis, Fusobacterium, diphtheria, syphilis, and gonorrhea.[2][3][4][5] A coexisting GABHS and influenza A virus pharyngotonsillitis has been reported.[9]
Anaerobic bacteria have been implicated in tonsillitis and a possible role in the acute inflammatory process is supported by several clinical and scientific observations.[10]
Under normal circumstances, as viruses and bacteria enter the body through the nose and mouth, they are filtered in the tonsils.[11][12] Within the tonsils, white blood cells of the immune system destroy the viruses or bacteria by producing inflammatory cytokines like Phospholipase A2,[13] which also lead to fever.[11][12] The infection may also be present in the throat and surrounding areas, causing inflammation of the pharynx.[14]
Sometimes, tonsillitis is caused by an infection of spirochaeta and treponema, in this case called Vincent's angina or Plaut-Vincent angina.[15]
Laboratory tests
The diagnosis of GABHS tonsillitis can be confirmed by culture of samples obtained by swabbing both tonsillar surfaces and the posterior pharyngeal wall and plating them on sheep blood agar medium. The isolation rate can be increased by incubating the cultures under anaerobic conditions and using selective media. A single throat culture has a sensitivity of 90%-95% for the detection of GABHS. A small percentage of false-negative results are part of the characteristics of the tests used but are also possible if the patient has received antibiotics prior to testing. Identification requires 24 to 48 hours by culture but rapid screening tests (10–60 minutes), which have a sensitivity of 85-90%, are available. Older antigen tests detect the surface Lancefield group A carbohydrate. Newer tests identify GABHS serotypes using nucleic acid (DNA) probes or polymerase chain reaction. Bacterial culture should be performed in cases of a negative rapid streptococcal test.[16]
True infection with GABHS, rather than colonization, is defined as the presence of >10 colonies of GABHS per blood agar plate. However, this method is difficult to implement because of the overlap between carriers and infected patients. An increase in antistreptolysin O (ASO) streptococcal antibody titer 3–6 weeks following the acute infection can provide retrospective evidence of GABHS infection.[17] ASO titers are considered definitive proof of GABHS infection.
When GAHBS is not isolated, the clinician should seek other potential pathogens. However, many of these organisms are part of the normal flora residing in the pharynx, making interpretation of the results difficult. A finding of a membrane in the throat should prompt a search for corynebacteria. Culture should be obtained from beneath the membrane, and use of a special moisture-reducing transport medium is necessary. The material may be inoculated on a Loeffler slant, tellurite plate, or blood agar plate. Identification by fluorescent antibody technique is also possible. Viral cultures are available, as well as rapid tests for some viruses (e.g., respiratory syncytial viruses). A heterophile slide test or other rapid test for infectious mononucleosis can provide a specific diagnosis.
Tonsillitis and Rheumatic Fever
Since the advent of Penicillin in the 1940's, a major preoccupation in the treatment of streptococcal tonsillitis has been the prevention of rheumatic fever, and it's major effects on the nervous system (Sydenham's chorea) and heart. Recent evidence would suggest that the rheumatogenic strains of group A beta hemolytic strep have become markedly less prevalent and are now only present in small pockets such as in Salt Lake City.[18] This brings into question the rational for treating tonsillitis.
Treatment
Treatments to reduce the discomfort from tonsillitis symptoms include:[2][3][4][5][14][19][20]
- pain relief, anti-inflammatory, fever reducing medications (acetaminophen/paracetamol and/or ibuprofen)
- sore throat relief (warm salt water gargle, lozenges, and iced/cold liquids)
If the tonsillitis is caused by group A streptococus, then antibiotics are useful with penicillin or amoxicillin being first line.[21] Cephalosporins and macrolides are considered good alternatives to penicillin in the acute setting.[22] A macrolide such as erythromycin is used for people allergic to penicillin. Individuals who fail penicillin therapy may respond to treatment effective against beta-lactamase producing bacteria[23] such as clindamycin or amoxicillin-clavulanate. Aerobic and anaerobic beta lactamase producing bacteria that reside in the tonsillar tissues can "shield" group A streptococcus from penicillins.[24] When tonsillitis is caused by a virus, the length of illness depends on which virus is involved. Usually, a complete recovery is made within one week; however, symptoms may last for up to two weeks. Chronic cases may be treated with tonsillectomy (surgical removal of tonsils) as a choice for treatment.[25]
Causes of penicillin failure in the treatment of GABHS tonsillitis
Despite its excellence in vitro efficacy, the frequently reported inability of penicillin to eradicate GABHS from patients with acute and relapsing tonsillitis is a cause for concern. Over the past 50 years, the rate of penicillin failure has consistently increased from about 7% in 1950 to almost 40% in 2000.[26]
There are several explanations for the failure of penicillin to eradicate GABHS tonsillitis (Table 1). One explanation is the poor penetration of penicillin into the tonsillar tissues as well as into the epithelial cells.[27] Other explanations relate to the bacterial interactions between GABHS and the other members of the pharyngo-tonsillar bacterial flora. It is hypothesized that the enzyme beta-lactamase which is secreted by beta-lactamase-producing aerobic and anaerobic bacteria, that colonize the pharynx and tonsils, may "shield" GABHS from penicillins.[28] These organisms include S. aureus, Haemophillus influenzae, and Prevotella, Porphyromonas and Fusobacterium spp.,[29] A recent increase was noted in the recovery of MRSA which was isolated from 16% of tonsils, making it more difficult to eradicate this and other beta-lactamase producing organisms.[30] Another possibility is the coaggregation between Moraxella catarrhalis and GABHS, which can facilitate colonization by GABHS.[31] Normal bacterial flora can interfere with the growth of GABHS,[32][33] and the absence of such competitive bacteria makes it easier for GABHS to colonize and invade the pharyngo-tonsillar area.[34] GABHS can also be reacquired from a contact or an object (i.e., toothbrush or dental braces)[35]
Table 1. Causes of Antibiotics Failure in Therapy of GABHS Tonsillitis
- The presence of beta-lactamase–producing organisms that "protect" GABHS from penicillins[36]
- Coaggregation between GABHS and M. catarrhalis[31]
- Absence of members of the oral bacterial flora capable of interfering with the growth of GABHS (through production of bacteriocins and/or competition on nutrients)[32][33]
- Poor penetration of penicillin into the tonsillar cells and tonsillar surface fluid ( allowing intracellular survival of GABHS)[27]
- Resistance (i.e., erythromycin) or tolerance (i.e., penicillin) to the antibiotic used
- Inappropriate dose, duration of therapy, or choice of antibiotic
- Poor compliance
- Reacquisition of GABHS from a contact or an object (i.e., toothbrush or dental braces)[35]
- Carrier state, not disease[37]
Implications of microbial interactions on therapy
Penicillin is recommended by some guidelines as the antibiotic of choice,[38] although other antibiotics are more effective in the bacteriologic and clinical cure of acute and recurrent GABHS tonsillitis.[39][40][41][42][43] Lincomycin, clindamycin, and amoxicillin-clavulanate are more effective in relapsing GABHS tonsillitis.[39][40][41] Cephalosporins are superior to penicillins in both acute and relapsing GABHS tonsillitis.[44][45] In those who failed penicillin, the goal of therapy is to eradicate the beta-lactamase-producing bacteria that "shield" GABHS from penicillin, while preserving whatever "protective" interfering organisms (i.e., alpha hemolytic streptococci) that may colonize the tonsils. Cephalosporins have been successful in eradicating GABHS better,[46] and in some instances even faster[47] than penicillins. Their efficacy is explained by their activity against beta-lactamase producing aerobic bacteria, and sparing of interfering organisms.[17] Over 35 randomized studies had demonstrated cephalosporins of all generations to have a much higher success rate in eradicating GABHS than penicillin (a third of the failure rate of penicillin),[46] and 12 studies found equal or better success rate in 5 to 7 days of therapy as compared with 10 days of penicillin.[48][49]
Complications
Complications may rarely include dehydration and kidney failure due to difficulty swallowing, blocked airways due to inflammation, and pharyngitis due to the spread of infection.[2][3][4][5][14]
An abscess may develop lateral to the tonsil during an infection, typically several days after the onset of tonsillitis. This is termed a peritonsillar abscess (or quinsy). Rarely, the infection may spread beyond the tonsil resulting in inflammation and infection of the internal jugular vein giving rise to a spreading septicaemia infection (Lemierre's syndrome).
In chronic/recurrent cases (generally defined as seven episodes of tonsillitis in the preceding year, five episodes in each of the preceding two years or three episodes in each of the preceding three years),[50][51][52] or in acute cases where the palatine tonsils become so swollen that swallowing is impaired, a tonsillectomy can be performed to remove the tonsils. Patients whose tonsils have been removed are still protected from infection by the rest of their immune system.
In very rare cases of strep throat, diseases like rheumatic fever[53] or glomerulonephritis[54] can occur. These complications are extremely rare in developed nations but remain a significant problem in poorer nations.[55][56] Tonsillitis associated with strep throat, if untreated, is hypothesized to lead to pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS).[57]
