VET: Disinfectants for foot-and-mouth disease were sprayed on livestock barns and roads from early February to May 2011. Although 90% of the disinfectant was concentrated on the roads, 10% was sprayed on cattle sheds and other sites where foot-and-mouth disease occurred. Since the outbreak of foot-and-mouth disease in November 2010, there has been a steady increase in disinfectant use. Consequently, its adverse environmental effects have prompted government officials to take preventive measures. The major chemical components of the disinfectants are citric acid, potassium sulfate base complex, quaternary ammonium compound, malic acid, and glutaraldehyde, ranging in amounts from tons to hundreds of tons. The exact amount of each component of the disinfectants could not be identified because the types of components used in the different commercial formulations overlapped. In this review, we obtained information on disinfectants that are widely used nationwide, including the types of major chemical components and their respective toxicities (both human and ecological).

4.2 Drug Warning

... A 43-year-old woman /developed/ an acute hemorrhagic colitis after colonoscopy with ambulatory anesthesia. The diagnosis is likely to have been glutaraldehyde induced colitis (used for disinfection of the endoscope). The patient recovered spontaneously completely.

Six eyes of 6 patients developed toxic anterior segment syndrome (TASS) after uneventful phacoemulsification cataract surgery with implantation of a 3-piece acrylic IOL performed by 2 ophthalmologists on the same day. Clinical findings included corneal edema, Descemet's membrane folds, anterior chamber reaction, fibrin formation, and irregular, dilated, and unreactive pupils. ... Glutaraldehyde 2% solution was used inadvertently by the operating room staff who cleaned and sterilized reusable ocular instruments before autoclaving. None of the affected corneas improved. Additional surgical procedures were required and included penetrating keratoplasty, trabeculectomy, and glaucoma tube implantation. CONCLUSIONS: Glutaraldehyde in concentrations generally used for cold sterilization is highly toxic to the corneal endothelium. The operating room staff involved in sterilizing instruments should be well educated about and careful to follow the protocols to properly clean and sterilize reusable ocular instruments.

The medical records of patients with acute rectocolitis following endoscopy treated at Kaohsiung Veterans General Hospital since 2001 were reviewed. The indication of endoscopy was health check-up for all patients. Published English-language studies regarding acute rectocolitis following endoscopy were also reviewed. RESULTS: An outbreak of six patients occurred in April 2002 and one cirrhotic patient was admitted in July 2008. All patients developed a self-limited syndrome of abdominal pain and bloody diarrhea within 48 h of uncomplicated endoscopy. One severely ill patient required hospitalization to receive intravenous fluid and antibiotics. After the investigation in April 2002, glutaraldehyde-induced colitis was diagnosed due to a defect in the endoscope-cleansing procedure. There were no deficiencies in the cleansing procedure in July 2008. Considering the patient's concomitant disease, we postulated that ischemic colitis with cirrhosis-related intestinal inflammation and endotoxemia was the possible diagnosis in this sporadic case. CONCLUSIONS: Endoscopists should be aware of this iatrogenic complication in patients presenting with acute rectocolitis, especially in those who have undergone recent endoscopic examination. An outbreak of acute rectocolitis following endoscopy should be considered glutaraldehyde-induced and should lead to an investigation of cleansing and equipment-disinfection procedures. In the absence of strong evidence of an outbreak, an infectious disease, or contamination of glutaraldehyde, a sporadic case should be considered ischemic colitis especially in patients with relevant concomitant diseases or predisposing factors.

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Disinfectants

Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed) (See all compounds classified as Disinfectants.)


Fixatives

Agents employed in the preparation of histologic or pathologic specimens for the purpose of maintaining the existing form and structure of all of the constituent elements. Great numbers of different agents are used; some are also decalcifying and hardening agents. They must quickly kill and coagulate living tissue. (See all compounds classified as Fixatives.)


Cross-Linking Reagents

Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other. (See all compounds classified as Cross-Linking Reagents.)


5.2 Absorption, Distribution and Excretion

Glutaraldehyde is readily absorbed by oral, iv, and inhalation routes. It is absorbed dermally to a lesser extent.

Dart, R.C. (ed). Medical Toxicology. Third Edition, Lippincott Williams & Wilkins. Philadelphia, PA. 2004., p. 1249


In rats, glutaraldehyde is eliminated in the urine and expired gases.

Dart, R.C. (ed). Medical Toxicology. Third Edition, Lippincott Williams & Wilkins. Philadelphia, PA. 2004., p. 1249


Dermal and intravenous studies in the rat with dilute aqueous glutaraldehyde solutions (0.075-7.5%) showed that, in dermal tests, approx 5% was absorbed in the rat, and 30-50% in the rabbit. In the intravenous injection tests, approx 12% was absorbed in the rat and approx 33% in the rabbit. There were no significant differences between males and females in the study. The dermal absorption rate constant was low (0.2-2 hr) in each species. The elimination times were long for both intravenous injection (t0.5 for the rat 10 hr, rabbit 15-30 hr) and dermal application (t0.5 for the rat 40-110 hr, rabbit 20-100 hr), possibly due to the binding of glutaraldehyde to protein and the slow excretion of metabolites. The principal metabolite in both species was CO2 with other metabolites not identified. /It was/ proposed that the metabolism probably involved initial oxidation to corresponding carboxylic acids by aldehyde dehydrogenase, and then further oxidation to CO2.

Material balance and pharmacokinetic studies were conducted with rats & rabbits including iv or topical dosing with [14C]glutaraldehyde. Intravenous dosing resulted in radiochemical recovery from 86% to 101%. Principal route of recovery was as CO2 at 22% to 80% of the administered dose (7%-28% urinary, 0.2%-5% feces). Epicutaneous dosing resutled in radiochemical recovery primarily in the skin at the site of application (31%-61%) with no consistent accumulation in any other tissue. Rabbits absorbed 33% to 53% of the epicutaneously administered dose & rats absorbed 4.1% to 8.7%. Pharmacokinetic studies indicated percutaneous radiochemical absorption of 0.3% to 2.1% for rats & 2.5% to 15.6% for rabbits under conservative study conditions that are likely to overestimate potential human exposure conditions.

5.3 Metabolism/Metabolites

Glutaraldehyde is either metabolized by aldehyde dehydrogenase to yield an acid or inactivated by a reaction with sulphydryl groups using glutathione.

Dart, R.C. (ed). Medical Toxicology. Third Edition, Lippincott Williams & Wilkins. Philadelphia, PA. 2004., p. 1249


... In the intravenous injection tests, approx 12% was absorbed in the rat and approx 33% in the rabbit ... The principal metabolite in both species was CO2 with other metabolites not identified. /It was/ proposed that the metabolism probably involved initial oxidation to corresponding carboxylic acids by aldehyde dehydrogenase, and then further oxidation to CO2.

5.4 Biological Half-Life

The elimination times were long for both intravenous injection (t0.5 for the rat 10 hr, rabbit 15-30 hr) and dermal application (t0.5 for the rat 40-110 hr, rabbit 20-100 hr), possibly due to the binding of glutaraldehyde to protein and the slow excretion of metabolites.
