Infections Gastrointestinal tract

Lactoferrin Cow Anti-arthritic gastrointestinal tract infections... 

The spectrum of gastrointestinal tract infections (GTI) cover a wide spectrum from asymptomatic Helicobacter pylori gastritis to self-limiting viral gastroenteritis to food poisoning to bacterial enterocolitis to antibiotic-associated Clostridium difficile colitis to typhoid fever with sepsis and multi-organ failure.

Macrolide antibiotics are bacteriostatic for gram-positive and -negative bacteria therefore, they inhibit bacteria reproduction but do not kill the bacteria. Bacteria are killed by the immune system. Macrolide antibiotics are prescribed for soft tissue, skin, respiratory, and gastrointestinal tract infections. 

When used parenterally, neomycin causes renal damage and ototoxicity. It is used topically and for local actions, including gastrointestinal tract infections and sterilization prior to bowel surgery. In hepatic coma, neomycin is used (with decreased protein intake) to suppress col-iform bacteria, thus reducing ammonia intoxication. The answer is (E). 

Use roots to make mucilaginous tea that is antibacterial and anti-inflammatory. Helpful for soothing gastrointestinal tract infections (including mouth and throat), as it coats and soothes, reduces inflammation, and attacks microbial infection.

Many parasitic worms cause systemic infections outside the gastrointestinal tract. These include Strong loides stercoralis (threadworm), Trichinella spiralis Dracunculus medinensis and the several species of nematodes that cause filariasis (Mansonellaperstans and Onchocerca volvulus). 

As with all drugs, the specific side effects of the quinolones must be considered when they are chosen for treatment of bacterial infections [5]. Reactions of the gastrointestinal tract and the central neivous system are the most often observed adverse effects during therapy with quinolones. It should be underlined, however, that compared with many other antimicrobials, diarrhea is less frequently observed during quinolone treatment. Antibiotic-associated colitis has been observed rarely during quinolone therapy. Similarly, hypersensitivity reactions, as observed during therapy with penicillins and other (3-lactams, is less frequently caused by quinolones. Some other risks of quinolone therapy have been defined and must be considered if a drug from this class is chosen for treatment of bacterial infections. 

DIARRHEA Diarrhea may be an indication of a super-infection of the gastrointestinal tract or pseudomembranous colitis. The nurse inspects all stools and notifies the primary health care provider if diarrhea occurs because it may be necessary to stop the drug. If diarrhea does occur and there appears to be blood and mucus in the stool, it is important to save a sample of the stool and test for occult blood using a test such as Hemoccult. If the stool tests positive for blood, the nurse saves the sample for possible further laboratory analysis. 

The cephalosporins also may be used perioperatively, that is, during the preoperative, intraoperative, and postoperative periods, to prevent infection in patients having surgery on a contaminated or potentially contaminated area, such as the gastrointestinal tract or vagina In some instances, a specific drug may be recommended for postoperative prophylactic use only. 

Cranberry Vaccinium macrocarpon Urinary tract infection (UTI) Large doses can produce gastrointestinal symptoms (je, diarrhea) None significant. 

In severe cases, or those refractory to treatment, truncal and limb weakness may be accompanied by involvement of masticatory, bulbar, and respiratory muscles. However the most life-threatening clinical manifestations are those affecting the gastrointestinal tract, since stomach ulceration can occur and death from perforation and peritonitis are not unknown. Medication with steroidal antiinflammatory agents is necessary but weakens the childrens resistance to infection, so that systemic spread of usually self-limiting disorders, such as candidiasis, may occasionally occur. 

Nystatin has a specific action on C. albicans and is of no value in the treatment of any other type of infection. It is poorly absorbed from the gastrointestinal tract even after very large doses, the blood level is insignificant. It is administered orally in the treatment of oral thrush and intestinal candidiasis infections. 

Amphotericin B is particularly effective against systemic infections caused by C. albicans and Cryptococcus neoformans. It is poorly absorbed from the gastrointestinal tract and is thus usually administered by intravenous injection under strict medical supervision. Amphotericin B methyl ester (Fig. 5.15C) is water-soluble, unlike amphotericin B itself, and can be administered intravenously as a solution. The two forms have equal antifungal activity but higher peak serum levels are obtained with the ester. Although the ester is claimed to be less toxic, neurological effects have been observed. An ascorbate salt has recently been described which is water-soluble, of similar activity and less toxic. 

Humoral antibodies of the IgG elass are able to eross the placenta flxm mother to fetus. These antibodies will provide passive proteetion of the new-born against those diseases which involve humoral immunity and to which the mother is immune. In this fashion, new-born infants in the UK have passive proteetion against tetanus but not against tuberculosis which requires cell-mediated immunity. Seeretory antibodies are also passed to the new-born together with the first deliveries of breast milk (colostrum). Such antibodies provide some passive protection against infections of the gastrointestinal tract. 

Yamashita reported anti-inflammatory effect of astaxanthin when administered with aspirin. An oral preparation has been developed by Alejung and Wadstroem for the treatment of Helicobacter infections of the mammalian gastrointestinal tract. Strong evidence suggested that astaxanthin modulated the humoral and non-humoral immune systems. It enhanced the release of interleukin-1 and tumor necrosis factor-... 

Some people show first evidence of IBS after contracting gastroenteritis, which has led to speculation about whether an infection makes the gastrointestinal tract susceptible to functional problems. Women with IBS may have symptoms triggered by menstrual periods. 

Irritable bowel syndrome (IBS) is a disorder of the gastrointestinal tract that interferes with the normal functions of the colon. At various points in the past, IBS has been referred to as mucous colitis, spastic colon, irritable colon, or nervous stomach. IBS is generally described as afunctional disorder rather than a disease per se. A functional disorder involves symptoms that cannot be attributed to a specific injury, infection, or other physical problem. A functional disorder occurs because of altered physiologic processes rather than structural or biochemical defects and may be subject to nervous system influence. IBS is associated with frequent fluctuation in symptoms, loss of productivity, and decreased quality of life. Although IBS has been referred to as functional bowel disease, true functional bowel disease may be more indicative of widespread gastrointestinal involvement including (but not limited to) the colon. 

Acute pancreatitis can progress to several distinct consequences. Pancreatic fluid collections and pancreatic abscesses can form during the course of acute pancreatitis. Pancreatic necrosis can occur when pancreatic enzymes damage the pancreatic tissue or when pancreatic abscesses become secondarily infected. This infection is usually due to bacteria that are normally found in the gastrointestinal tract, including Escherichia coli, Enterobacteriaceae, Staphylococcus aureus, viridans group streptococci, and anaerobes.
