Peptic ulcer disease diagnosis

A 46-year-old woman is prescribed doxycycline for a diagnosis of community-acquired pneumonia. Her PMH is significant for iron-deficiency anemia, peptic ulcer disease, HTN, a recent DVT, and headaches. Her current medications include ferrous sulfate, ibuprofen, enalapril, acetaminophen, famotidine, and warfarin. Which of her following medications is most likely to result in decreased levels of doxycycline ... 

The growth in endoscopic procedures, with direct visualization of the interior of the stomach, has largely removed the need for the clinical laboratory to carry out the analysis of gastric contents. Situations remain, however, in which the laboratory continues to play a significant role in the diagnosis of gastric diseases and in monitoring the effectiveness of treatment. This section describes peptic ulcer disease and tests for Helicobacter pylori H. pylori) and the measurement of basal acid output from the stomach. 

Although the incidence of peptic ulcer disease has steadily declined in the United States since the turn of the twentieth century, approximately 500,000 new cases and 4 million recurrences annually are reported. In 1990, it was estimated that the annual direct cost related to diagnosis and treatment of peptic ulcer disease in the United States was between 3 and 4 billion dollars, compared to the 2.5 million dollars estimated in 1975. 

On determination of clinical symptomatology consistent with a putative diagnosis of peptic ulcer disease, the site and nature of the lesion should be identified. Thus, at endoscopy, the presence and site of the ulcer, as well as the... 

Peptic ulcer disease is claimed to affect about 10% of the population over a lifetime and 3 % annually [2]. Peptic ulcer prevalence seems to be a cohort phenomenon closely connected to Helicobacter pylori Hp) infection [3], which is decreasing in the industrialized world due to the lower infection rate among younger people [2, 4]. Diagnosis of peptic ulcer is based on endoscopy or X-ray. In patients with earlier confirmed ulcer and repeated symptoms, diagnosis can be made on this ground. 

Amylase enters the blood largely via the lymphatics. An increase in hydrostatic pressure in the pancreatic ducts leads to a fairly prompt rise in the amylase concentration of the blood. Neither an increase in volume flow of pancreatic juice nor stimulation of pancreatic enzyme production will cause an increase in senm enzyme concentration. Elevation of intraductal pressure is the important determinant. Stimulation of flow in the face of obstruction can, however, augment the entry of amylase into the blood, as can disruption of acinar cells and ducts. A functional pancreas must be present for the serum amylase to rise. Serum amylase determination is indicated in acute pancreatitis in patients with acute abdominal pain where the clinical findings are not typical of other diseases such as appendicitis, cholecystitis, peptic ulcer, vascular disease or intestinal obstruction. In acute pancreatitis, the serum amylase starts to rise within a few hours simultaneously with the onset of symptoms and remains elevated for 2 to 3 days after which it returns to normal. The peak level is reached within 24 hours. Absence of increase in serum amylase in first 24 hours after the onset of symptoms is evidence against a diagnosis of acute pancreatitis (76). 

The movement of larval and adult parasites produces several pathological changes like inflammation of the cells, allergic reactions and eosinophilia. The clinical manifestations of the disease include attacks of diarrhea, diffused abdominal pain, epigastric discomfort and hunger pains, which may lead to false diagnosis of peptic ulcer. Heavy infections may cause malabsorption, flatulence and abdominal disten-...
