what is empiric treatment

Empiric antimicrobial therapy is directed against an anticipated and likely cause of infectious disease. It is used when antimicrobials are given to a person before the specific bacterium or fungus causing an infection is known. When it becomes known, treatment that is used is called directed therapy.

Is proton pump inhibitor effective?

Empirical treatment with a proton pump inhibitor is a less effective strategy than first establishing Helicobacter pylori status and eradicating appropriately before starting proto n pump inhibitor therapy only in those who are Helicobacter pylori negative. In a controlled trial 219 patients under 45 years of age, without alarm symptoms, were randomized to omeprazole 20 mg/day or eradication therapy if Helicobacter pylori positive, or to omeprazole 20 mg/day if Helicobacter pylori negative (22 C ). Endoscopy was done if symptoms recurred or there was no improvement. In the first group 96/109 patients required endoscopy compared with 61/110 of the second group. There were nine duodenal scars in the first group. Thus, eradication therapy reduces the need for endoscopy in patients aged under 45 years without alarm symptoms. Empirical treatment is likely to result in recurrence and can mask peptic ulcers and esophagitis.

Is dexamethasone more effective than MP?

The early empirical treatment of peritumoral edema and acute SCI with glucocorticoid steroids was heavily weighted toward the use of dexamethasone based on the fact that it was, and is, the most potent synthetic glucocorticoid steroid available for parenteral use. Dexamethasone is about five times more potent than MP in regard to glucocorticoid receptor affinity and anti-inflammatory potency (Schimmer and Parker, 2001). However, it has been found that the antioxidant efficacy of MP is unrelated to its glucocorticoid steroid receptor activity (Hall et al., 1987). Indeed, a careful concentration-response study has compared the ability of different glucocorticoid steroids to inhibit oxygen radical-induced LP damage in rat brain synaptosomal preparations and confirmed that LP-inhibiting potencies and anti-inflammatory potencies do not correlate. Although dexamethasone is five times more potent than MP as a glucocorticoid, it is only slightly more potent than MP as an inhibitor of LP (Braughler, 1985). Furthermore, the maximal antioxidant activity of MP appears to be superior to that for dexamethasone. The prototype glucocorticoid hydrocortisone is completely lacking in ability to inhibit oxygen radical damage in CNS tissue. Thus, the choice of a steroid for its potential antioxidant neuroprotective activity should not be predicated on glucocorticoid receptor-mediated anti-inflammatory actions. In addition, selection of the most potent glucocorticoid would logically carry the greatest potential for concomitant steroid-related side effects.

What is empiric treatment?

Treatment is generally started empirically, on the basis of surveillance data about the local common bacterial causes. This first treatment, based on statistical information about former patients, and aimed at a large group of potentially involved microbes, is called empiric treatment.

What is empirical therapy?

Empiric therapy or empirical therapy is medical treatment or therapy based on experience and, more specifically, therapy begun on the basis of a clinical "educated guess" in the absence of complete or perfect information. Thus it is applied before the confirmation of a definitive medical diagnosis or without complete understanding of an etiology, whether the biological mechanism of pathogenesis or the therapeutic mechanism of action. The name shares the same stem with empirical evidence, involving an idea of practical experience.

What were the theories of etiology, pathogenetic mechanism, and therapeutic mechanism of action based on

For example, in the era of ancient Greece, when medical science as we now know it did not yet exist, all medicine was unscientific and traditional; theories of etiology, pathogenetic mechanism, and therapeutic mechanism of action were based on religious, mythologic, or cosmologic ideas.
