Infection Conjunctivitis

Inflammatory conditions Treatment of steroid-responsive inflammatory conditions of the palpebral and bulbar conjunctiva, lid, sclera, cornea, and anterior segment of the globe, such as Allergic conjunctivitis acne rosacea superficial punctate keratitis herpes zoster keratitis iritis cyclitis and selected infective conjunctivitis (when the inherent hazard of steroid use is accepted to obtain an advisable diminution in edema and inflammation [prednisolone]) vernal conjunctivitis episcleritis epinephrine sensitivity and anterior uveitis. 

The patient has infective conjunctivitis, which usually starts in one eye and can spread to both eyes. Conjunctivitis is inflammation of the conjunctiva, a protective membrane covering the white of the eye and inside surface of eyelids, due to allergy, infection or physical irritation. For infective causes, both bacteria and viruses can be responsible, with staphylococcal species common bacterial causes and adenoviruses for viral cases, with the latter more common in adults. 

Symptoms of infective conjunctivitis include conjunctiva hyperaemia, making the sclera of the eye appear red, usually bilaterally for infective and allergy-related cases and an uncomfortable superficial gritty eye sensation. Bacterial infections tend to have the presence of a yellow-white muco-purulent discharge and a papillary reaction (small bumps on the conjunctiva appearing as a fine velvety surface), compared with a more watery discharge for viral or allergy-related causes. 

Infective conjunctivitis is usually a self-limiting, non-harmful condition, with spontaneous symptom resolution within 2-14 days that is not dependent upon treatment. Within a pharmacy setting, it may be appropriate to treat any superficial infective conjunctivitis, in the absence of any requirement to refer a patient to a doctor, with chloramphenicol eye drops, which current clinical opinion suggests as the first-line choice, as sometimes it is difficult clinically to... 

Bacteria and viruses are both causes of infective conjunctivitis and it may be clinically difficult to distinguish between them. Over-the-counter treatment of any superficial infective conjunctivitis with an antibacterial agent is considered appropriate, as it may help prevent secondary bacterial infection. 

In humans, the adult eyeball measures approximately one inch (2.5 centimeters) in diameter, and of its total surface area, only the anterior one-sixth is exposed to the external environment. This exposed area is protected by accessory structures of the eye, including the eyelids, eyelashes, eyebrows, lacrimal (tearing) apparatus, and extrinsic eye muscles. Each eyelid possesses a conjunctiva, which is a thin, transparent, and protective mucus membrane. The conjunctiva lines the inner aspect of the eyelids as the palpebral conjunctiva and folds back (reflects) over the eyelids onto the anterior exposed surface of the eyeball as the bulbar (ocular) conjunctiva. The bulbar conjunctiva covers only the white of tlae eye (not the cornea that covers over the iris and pupil). Because tlie bulbar conjunctiva is quite thin, blood vessels are clearly visible beneath it. When these blood vessels are dilated and congested from local irritation or infection (conjunctivitis, or inflammation of the conjunctiva), the result is the appearance of reddened and irritated bloodshot eyes. 

Dexamethasone is a steroid antibiotic combination. Tobramycin inhibits bacterial protein synthesis, causing death dexamethasone suppresses the inflammatory response. The combination is indicated in superficial bacterial ocular infection or risk of bacterial ocnlar infection inflammatory conditions of palpebral and bulbar conjunctiva, cornea, and anterior segments of globe where inherent risk of steroid use in certain infective conjunctivitis is accepted to obtain a diminution of edema and inflammation chronic anterior uveitis and comeal injury from chemical, radiation, or thermal bums, or penetration of foreign bodies, where risk of superficial ocular infection is high, or an expectation, or when potentially dangerous numbers of bacteria will be present in the eye.

Nonspecific immunosuppressive therapy in an adult patient is usually through cyclosporin (35), started intravenously at the time of transplantation, and given orally once feeding is tolerated. Typically, methylprednisone is started also at the time of transplantation, then reduced to a maintenance dose. A athioprine (31) may also be used in conjunction with the prednisone to achieve adequate immunosuppression. Whereas the objective of immunosuppression is to protect the transplant, general or excessive immunosuppression may lead to undesirable compHcations, eg, opportunistic infections and potential malignancies. These adverse effects could be avoided if selective immunosuppression could be achieved. Suspected rejection episodes are treated with intravenous corticosteroids. Steroid-resistant rejection may be treated with monoclonal antibodies (78,79) such as Muromonab-CD3, specific for the T3-receptor on human T-ceUs. Alternatively, antithymocyte globulin (ATG) may be used against both B- and T-ceUs. 

Physiological Effects. The sulfur and nitrogen mustards act first as cell irritants and finally as a cell poison on all tissue surfaces contacted. The first symptoms usually appear in 4—6 h (4). The higher the concentration, the shorter the interval of time between the exposure to the agent and the first symptoms. Local action of the mustards results in conjunctivitis (inflammation of the eyes) erythema (redness of the skin), which may be followed by blistering or ulceration and an inflammatory reaction of the nose, throat, trachea, bronchi, and lung tissue. Injuries produced by mustard heal much more slowly and are much more Fable to infection than bums of similar intensity produced by physical means or by other chemicals. 

In an unusual variant on the Chichibabin reaction, treatment of 3-hydroxypyridine with sodium amide at 200° affords 2,6-di-aminopyridine (21). Coupling of the product with benzenediazo-nium chloride gives phenazopyridine (22). This drug is used as an analgesic for the urinary tract in conjunction with antibacterial agents for treatment of urinary infections. 

These antibiotics are effective in the treatment of infections caused by a wide range of gram-negative and gram-positive microorganisms. The lincosamides are used for the more serious infections. In serious infections they may be used in conjunction with other antibiotics. 

Antibiotics possess antibacterial activity and are used in the treatment of eye infections. Sulfonamides possess a bacteriostatic effect against a wide range of gram-positive and gram-negative microorganisms. They are used in the treatment of conjunctivitis, comeal ulcer, and other superficial infections of the eye. See the Summary Drug Table Select Ophthalmic Preparations and Chapter 6 for additional information on the sulfonamides. 

It may be possible to increase the utility of our resources to treat influenza virus infection through combinations of antiviral agents with different modes of action (discussed in Cinatl et al. 2007a De Clercq and Neyts 2007). The sialidase inhibitors, for example, may be able to be used in conjunction with the adamantane-based M2 ion channel inhibitors (Govorkova et al. 2004 Ilyushina et al. 2006), with Ribavirin (Smee et al. 2002) or with non-influenza virus specific therapeutics such as anti-inflammatory drugs (Carter 2007). Combination therapy may also reduce the potential of resistance development (Ilyushina et al. 2006). 

The natural killer cells (NK) are the host s primary innate immune responders against viral infections. Studies have shown morphine to suppress the cytolytic activity of NK cells (Shavit et al. 2004). In vivo studies carried out in the Indian rhesus macaques looked at chronic morphine administration and SIV the equivalent of HIV in apes. This group concluded that morphine contributed to the pathogenesis of Simian Immunodeficiency Virus (SIV) infection and that this contribution occurred in conjunction with the replication of viral proteins including Tat (Noel and Kumar 2006 Noel et al. 2006). 

As the name implies, these organisms grow in pairs, otherwise they are similar to streptococci and are now referred to as streptococci. Streptococcus pneumoniae is the causal agent of acute lobar pneumonia and also of meningitis, peritonitis and conjunctivitis. This organism can also initiate an invasive infection. 

The serum concentration of a number of proteins increases dramatically during infection. Their levels can increase by up to 100-fold compared with normal levels. They are known collectively as acute phase proteins and certain of them have been shown to enhance phagocytosis in conjunction with complement. 

Staphylococcus, Moraxella, or other opportunistic bacteria typically cause chronic conjunctivitis.10 Moraxella infections may cluster in groups of women who share makeup.12 Both acute and chronic bacterial conjunctivitis are self-limiting except if caused by staphylococci.13 Because of this, the pathogens are rarely cultured unless the case is unresponsive to treatment. While infection typically begins in one eye, it will often spread to both within 48 hours.11... 

Hyperacute bacterial conjunctivitis is associated with gonococcal infections in sexually active patients. The causative agents are Neisseria gonorrhoeae or N. meningitidis. Prompt work-up and treatment is required, as corneal perforation occurs in 10% of cases within 48 hours.12 An ophthalmologist should complete a conjunctival scraping and susceptibility testing.10... 

Treat acute bacterial conjunctivitis with broad-spectrum antibiotics. Although the condition is usually self-limiting, antibiotic treatment decreases the spread of disease to other people and prevents extraocular infection. Additionally, treatment may help decrease the risk of corneal ulceration or other complications that affect sight. Finally, treatment speeds recovery.14... 

Topical antivirals are not used to treat adenovirus conjunctivitis. Topical antibiotics are often prescribed for viral conjunctivitis, ostensibly to prevent bacterial superinfection. In reality, this is a case of the patient insisting on a medication to speed healing.11 Avoid the use of antibiotics for a viral infection.12 Eliminating superfluous antibiotic use also helps prevent the development of antibiotic resistance.
