Summary: - some efficacy in the treatment of toxicity associated with chloramphenicol and sulfasalazine - protective against cytotoxicity in severe sepsis and systemic inflammatory response syndrome - not effective against amyotrophic lateral sclerosis 113.
Pharmacogenetics is the study of the association between variability in drug response and or ; drug toxicity and polymorphisms in genes. The goal of this field of science is to adapt drugs to a patient's specific genetic background and therefore make them more efficacious and safe. In this article we describe the variants in genes that influence either the efficacy or toxicity of common drugs used in the treatment of inflammatory bowel diseases IBD ; , ulcerative colitis UC ; , and Crohn's disease CD ; including sulfasalazine and mesalazine, azathioprine AZA ; and 6-mercaptopurine 6-MP ; , methotrexate MTX ; , glucocorticosteroids CSs ; and infliximab. Furthermore, difficulties with pharmacogenetic studies in general and more specifically in IBD are described. Although pharmacogenetics is a promising field that already contributed to a better understanding of some of the underlying mechanisms of action of drugs used in IBD, the only discovery translated until now into daily practice is the relation between thiopurine S-methyltransferase TPMT ; gene polymorphisms and hematological toxicity of thiopurine treatment. In the future it is necessary to organize studies in well characterized patient cohorts who have been uniformly treated and systematically evaluated in order to quantitate drug response more objectively. An effort should be made to collect genomic DNA from all patients enrolled in clinical drug trials after appropriate informed consent for pharmacogenetic studies.

Sulfasalazine is used in ulcerative colitis and regional enteritis. Mafenide cream is used as a topical preparation for the prevention of infection of burns by a wide variety of gram-negative and gram-positive bacteria. It appears to be highly active in inhibiting the implantation of Pseudomonas aeruginosa but should not be used for established infection. There is rapid systemic absorption of mafenide. Adverse reactions include pain on application, allergic reactions, and loss of fluid by evaporation since occlusive dressings are not used. The drug inhibits carbonic anhydrase; the urine becomes alkaline, and metabolic acidosis may occur. Compensatory tachypnea with hyperventilation resulting in respiratory alkalosis can also occur. Silver sulfadiazine is also used extensively for topical therapy of burns. Silver is slowly released and is toxic to microorganisms. This drug prevents invasion and can also eradicate P. aeruginosa and other sensitive microorganisms from burns. Also, sulfonamides are potentially dangerous drugs. The overall incidence of reactions is about 5 per cent. Certain untoward effects preclude the subsequent use of these agents: drug fever and reaction involving the blood, bone marrow, kidney, liver, skin and peripheral nerves Sande and Mandell, 1985 ; . Hematopoietic side effects include acute hemolytic anemia, agranulocytosis, thrombocytopenia, aplastic anemia extremely rare ; , and eosinophilia. Renal side effects include crystalluria, toxic nephrosis, and hypersensitivity nephritis. The risk of crystalluria is reduced by large urine volume brought about by high fluid intake. Alkaline therapy can be used if urine pH is low. Hypersensitivity reactions include vascular lesions, which may resemble polyarteritis nodosa; skin and mucous membrane manifestations Stevens-Johnson syndrome ; , serum sickness, anaphylactoid reactions and drug fever. Liver damage may occur rarely. Other reactions include goiter, hypothyroidism, arthritis, neuropsychiatric disturbances, peripheral neuritis very rare ; , anorexia, nausea, and vomiting. Premature babies may develop kernicterus because of displacement of bilirubin from plasma protein binding sites. Enzymes that acetylate sulfonamides are poorly developed in newborns. Trimethoprim-Sulfamethoxazole The combination of trimethoprim-sulfamethoxazole has been used extensively since 1968, mainly for the treatment of gram-negative infections. The antibacterial spectrum of trimethoprim is similar to that of sulfamethoxazole, although the trimethoprim drug is 20 to 100 times more potent than the sulfamethoxazole Sande and Mandell, 1985 ; . The combination is active against most gram-positive and gram-negative bacteria but resistance may develop. Resistant organisms include P. aeruginosa, enterococci, and Bacteroides fragilis. Trimethoprim-sulfamethoxazole is a bacteriostatic combination; however, bactericidal activity may be found against some microorganisms. This combination works by acting on two levels in the pathway for the synthesis of tetrahydrofolic acid in bacteria. The sulfonamide inhibits the incorporation of PABA into folate, and trimethoprim blocks the 3.

Adverse side effects from Banamine in our rabbits, some of whom have had to receive it daily for a week or longer. Rimadyl is a newer anti-inflammatory drug which has been used with good results in rabbits. Torbugesic, an opioid analgesic, provides excellent pain relief at relatively low doses. Although some practitioners fear that an opioid might contribue to GI slowdown, pain can certainly do the same. We have used opiods repeatedly in cases like this, with very good results. We also have had excellent success at relieving colic pain and inflammation of the intestinal lining with sulfasalazine, a combination sulfa antibiotic and non-steroidal anti-inflammatory compound. Aulfasalazine works topically to reduce intestinal inflammation. Barium may also be useful as an intestinal tonic to relieve pain and help stimulate peristalsis, but its action is slow compared to that of the aforementioned analgesics. As always, your veterinarian is the one best able to decide which type of pain relief is best for your rabbit, given the specific conditions of his her illness. V. The Road to Recovery: Reduce Stress, and If it Ain't Broke, Don't Fix It. It is absolutely essential that the caretaker faced with a rabbit in GI stasis be patient, allowing the treatments and medications to work. Rabbits are easily stressed, and excessive handling should be avoided. It may take several days before any fecal pellets are seen, and it may take two weeks or more on intestinal motility agents and therapy before the intestine is moving normally again. We have had one case in which a rabbit produced no fecal pellets for 14 days, but finally did respond to gentle, consistent administration of the above treatment regimen. Patience and persistence are key! Do not make more trips to the veterinarian's office with the rabbit than absolutely necessary the stress of travel can slow recovery ; , but DO contact your veterinarian frequently to report on progress and any changes. Whenever possible, administer medications at home, where the rabbit feels safe and secure. While you are treating your sick bunny, NEVER separate him her from his her bonded partner s ; . The stress of separation itself can make the problem worse. We have known bunnies who seemed at death's door to recover when they were provided with the love and constant attention of their bonded mate. If your bunny does not have a mate, it is even more important that you, his best friend, show him a great deal of attention and affection during his ordeal. Rabbits seem to understand when they are being fussed over, and it may help them recover more quickly to know that they are not being abandoned in their misery. Every bunny parent should have a stethoscope not necessarily an expensive one ; to monitor intestinal sounds. The gradual return of gentle gurgling is a very good sign: once this begins, the rabbit is on the road to recovery, even if fecal pellets don't begin pouring out the chute. Administration of intestinal motility agents, gentle massage and supportive care as listed above should be continued, and gradually tapered as fecal pellets slowly begin to come through the system.

Caution should be used when NSAIDs and salicylates are administered concomitantly with lower doses of methotrexate. These drugs have been reported to reduce the tubular secretion of methotrexate in an animal model and may enhance its toxicity. Despite the potential interactions, studies of methotrexate in patients with rheumatoid arthritis have usually included concurrent use of constant dosage regimens of NSAIDs, without apparent problems. It should be appreciated, however, that the doses used in rheumatoid arthritis 7.5 to 15 mg week ; are somewhat lower than those used in psoriasis and that larger doses could lead to unexpected toxicity. Methotrexate is partially bound to serum albumin, and toxicity may be increased because of displacement by certain drugs, such as salicylates, phenylbutazone, phenytoin, and sulfonamides. Renal tubular transport is also diminished by probenecid; use of methotrexate with this drug should be carefully monitored. In the treatment of patients with osteosarcoma, caution must be exercised if high-dose methotrexate is administered in combination with a potentially nephrotoxic chemotherapeutic agent eg, cisplatin ; . Methotrexate increases the plasma levels of mercaptopurine. The combination of methotrexate and mercaptopurine may therefore require dose adjustment. Oral antibiotics such as tetracycline, chloramphenicol, and nonabsorbable broad spectrum antibiotics, may decrease intestinal absorption of methotrexate or interfere with the enterohepatic circulation by inhibiting bowel flora and suppressing metabolism of the drug by bacteria. Penicillins may reduce the renal clearance of methotrexate; increased serum concentrations of methotrexate with concomitant hematologic and gastrointestinal toxicity have been observed with high and low dose methotrexate. Use of methotrexate with penicillins should be carefully monitored. The potential for increased hepatotoxicity when methotrexate is administered with other hepatotoxic agents has not been evaluated. However, hepatotoxicity has been reported in such cases. Therefore, patients receiving concomitant therapy with methotrexate and other potential hepatotoxins eg, azathioprine, retinoids, sulfasalazine ; should be closely monitored for possible increased risk of hepatotoxicity. Methotrexate may decrease the clearance of theophylline; theophylline levels should be monitored when used concurrently with methotrexate. Vitamin preparations containing folic acid or its derivatives may decrease responses to systemically administered methotrexate. Preliminary animal and human studies have shown that small quantities of intravenously administered leucovorin enter the CSF primarily as 5-methyltetrahydrofolate and, in humans, remain 1 - 3 orders of magnitude lower than the usual methotrexate concentrations following intrathecal administration. However, high doses of leucovorin may reduce the efficacy of intrathecally administered methotrexate and adapalene.

Clinical Bottom Line Based on studies that compare medications for RA see "Confidence Scale" ; , we know that: For people with early RA less than 3 years' duration ; who have not previously taken methotrexate, monotherapy with methotrexate controls symptoms as well as the biologics adalimumab or etanercept. Level of confidence: Combining a biologic with methotrexate brings better symptom relief than using a biologic or methotrexate alone. Level of confidence: Combining methotrexate and sulfasalazine does not work better than monotherapy with either drug for people with early RA. Level of confidence: Evidence is insufficient to determine if combining two biologics works better than using any one biologic alone. Methotrexate and most biologics increase the likelihood of serious infection. Level of confidence: Types of RA Drugs.

All rotors are designed to carry a maximum load at a specific maximum speed. Since even one run made under conditions of excessive stress may significantly reduce the fatigue life of a rotor, it is important to abide by the operational specifications published in each rotor manual. Speed reductions required for running high-density solutions, plastic adapters, or stainless steel tubes should always be observed. Swinging bucket rotors must not be run with missing buckets, and sample loads should be balanced. For the rotors that utilize carbon-fiber composite cannisters, all cannisters must be used at all times, even if there is no bottle inside the cannister. Each Beckman Coulter ultracentrifuge rotor carries an overspeed disk that prevents it from exceeding its maximum rated speed through operator error or instrument malfunction. But it is the user's responsibility to be sure that the correct disk is on the bottom of the rotor, that the disk is in good condition, or that a speed-derating disk is installed if and when the warranty conditions requires it. With the exception of Zonal, Continuous Flow, Component Test and Rock Core ultracentrifuge rotors, rotor logging is not mandatory per warranty but may be desirable for good laboratory practices. Aluminum and swinging bucket rotors are to be retired after 10 years of service. Titanium rotors are to be retired after 12 years of service. Rotors for the Beckman Coulter J6 and J2 series of centrifuges, on the other hand, are protected from dangerous single-cycle overspeed condition by windage or by the power limitations of the drive. The Avanti J series centrifuges have a rotor identification system, which uses windage rotor inertia measurements or special magnets to automatically limit the maximum speed setting of the instrument. The centrifuge user should take care to prevent overspeeding by setting the proper run speed each time, because the fatigue life of the rotor will be reduced by this. The purchase date of each rotor should be recorded, however, and kept on permanent file. Note that the purchase date may be somewhat different from the manufacturing date shown in the rotor serial number. There is an expiration date permanently marked on some rotors and rotor accessories. The component must not be used beyond its expiration date under any circumstances and crotamiton.

In human medicine, anti-fertility effects of therapeutic drugs are a major concern. Studies have shown the sulfa drug sulfasalazine and its metabolite sulfapyridine to cause infertility in male rats5, 6 and humans7 by decreasing sperm motility and or sperm numbers and increasing morphologic defects. Similar anti-fertility effects have not been documented for sulfamethoxazole and sulfadiazine; the two most commonly used sulfa drugs in the horse. There are, however, clinical reports that suggest a possible detrimental effect of trimethoprim-sulfamethoxazole on the semen quality of human patients.8 Another folate inhibitor, pyrimethamine, is often combined with trimethoprim-sulfa in the treatment of EPM. Unlike trimethoprim-sulfa however, pyrimethamine clearly has adverse effects on male fertility.9, 10 Pyrimethamine does not seem to diminish reproductive hormone levels but significantly reduces testicular size and causes spermatogenic arrest when high doses are given for prolonged periods. It is suggested that the adverse effects on spermatogenesis are caused by the same anti-folate action that makes pyrimethamine an effective antimicrobial. When used in combination with two other antifolate medications trimethoprim-sulfa ; for the treatment of EPM, the synergistic action of all three drugs may have the potential to impact stallion fertility. Surprisingly, Bedford and McDonnell2 did not detect any adverse effects on semen quality of pony stallions treated with trimethoprimsulfa and pyrimethamine. They did, however, report that copulatory and ejaculatory function were adversely affected in four of six treated stallions in their study, and these effects mimicked those ob74 2002 Vol. 48 AAEP PROCEEDINGS and permethrin.

G&H Could you describe the initial studies of the 5-aminosalicylates for Crohn's disease? TB The first product containing 5-aminosalicylate 5-ASA ; was sulfasalazine. This agent was found to be effective in ulcerative colitis UC ; , and it was thought that the reason for its effectiveness was because bacteria split the sulfapyridine and 5-ASA molecule. 5-ASA is absorbed in the duodenum and is then excreted in the bile, at which point it enters the colon, where it is split by bacteria. Studies were conducted to further evaluate the efficacy of 5-ASA. In one study, patients with UC were given one of three different enemas, one containing sulfasalazine, another containing the antibiotic sulfapyridine, and a third containing 5-ASA.1 Patients who received the 5-ASA enema had a much better response than those who received sulfapyridine. The same study was then repeated with suppositories and included a few patients with Crohn's disease involving the rectum. Again, 5-ASA was confirmed as the active moiety of sulfasalazine.2 This finding was taken to be evidence that 5-ASA was the active ingredient, and led to the development of topical 5-ASAs, suppositories, enemas, and other ways to deliver 5-ASA. G&H Has the mechanism action, in which bacteria split the molecule, been confirmed over the years of 5-ASA use? TB One of the observations that has been made outside of the clinical trial setting is that patients with ileitis appear to benefit from sulfasalazine therapy, raising the question of whether the entire molecule might be effective, rather than only the split products. In the study by Azad Khan et al, 1 both the sulfasalazine enema and the 5-ASA enema were effective. It is safe to assume that there was no stool.

In six of the 54 cases, methotrexate 2 ; , acetaminophen 1 ; , celecoxib 1 ; , atorvastatin 1 ; and amiodarone 1 ; were listed as second co-suspect medications. Some of these drugs are rarely or never are associated with acute liver failure. We recognize that acetaminophen overdose and halothane inhalations have been associated with severe acute subacute liver injury. However in the cases presented here, these latter drugs do not appear to have been responsible for the acute hepatic event, or leflunomide was as likely to be the causative agent. In 39 54, % ; of reports, liver injury was probably caused by leflunomide per our causality assessment. Concurrent disease or other drugs were unlikely to have played a role in the development of serious liver injury. In the remaining 15 cases, the causal role of leflunomide was considered to be possible since other factors including concomitant medications and prior medical history could reasonably have contributed to the liver injury. Nine patients died. Eight deaths were liver-related and 1 was due to concurrent severe interstitial lung disease. One patient underwent liver transplantation.

Sk physicians to describe their "dream technique" for preventing breast cancer, and the answer might be something like this: Without surgery or other invasive procedures, doctors would detect precancerous cells in the breast before they become malignant and long before these cells begin amassing the genetic changes that make advanced tumors so difficult to treat. Then, with treatments tailored to specific cell types, they would treat only the area of the breast containing diseased tissue, averting the need for more extensive therapies later.
Sulfasalazine is a sulfa drug that has been used to treat rheumatoid arthritis since the 1930's. It not only decreases the pain and swelling of arthritis but also may prevent damage to joints and reduce the risk of long term disability.

Exposure to atrazine has been shown to attenuate the proestrus LH and prolactin surges in Long-Evans and Sprague-Dawley rats. Since both of these hormones are important for normal pubertal development, it is reasonable to hypothesize that atrazine may affect the onset of puberty in the female rodent. Atrazine's attenuation of the proestrus LH surge is described in detail in Part B sections 9.2.7 and 9.2.8. Atrazine's attenuation of prolactin release is described below in section 13.1. In addition, reports that atrazine can reduce hypothalamic norepinephrine concentrations Cooper et al., 1998 ; and that intravenous injections of GnRH restore the estrogen-induced secretion of LH in ovariectomized, atrazine-treated female rats Cooper et al., 2000 ; suggest that possible effects on neurotransmitters and their regulation of pituitary hormone synthesis secretion could also alter the onset of puberty. Thus, to examine the effects of atrazine on female pubertal development, a study was conducted using the "Research Protocol for the Assessment of Pubertal Development and Thyroid Function in Juvenile Female Rats" U.S. EPA, 1998b; Goldman et al., 2000 ; . 12.2.2 Male The onset of puberty in the male rat involves a complex interplay of several hormones including LH, FSH, testosterone and prolactin Nazian and Mahesh, 1980; Piacsek and Goodspeed, 1978 ; . It has been shown that an increased turnover rate in hypothalamic GnRH, NE and DA precedes the dramatic increase in testosterone Matsumoto et al., 1986 ; prior to the onset of puberty. LH stimulates testosterone secretion by the Leydig cells. At the same time, LH secretion varies only slightly as puberty approaches. However, there is an increased sensitivity of the testes to LH prior to puberty, due to other hormonal influences, such as increased prolactin secretion, that facilitate an upregulation of LH receptors Kamberi et al., 1980; Odell et al., 1973; Vihko et al., 1991 ; . In contrast, there is a higher threshold for the gonadotropin gonadal steroid feedback mechanism in the adult male Gupta et al., 1975; Nazian and Mahesh, 1980 ; as compared to the immature male, making the immature male more sensitive to the feedback of testosterone. As this feedback sensitivity decreases, the hypothalamic-pituitary unit becomes more effective at stimulating testicular development, because there is less inhibition of gonadotropins by testosterone and buy meloxicam.
