Cardizem

Description

In addition to considering the culprit organism and its vector blood pressure vertigo purchase cardizem 120 mg amex, one must also be aware of the susceptibility of the host. For example, persons with liver disease have an annual rate of infection with and death from Vibrio vulnificus that is 80 times and 200 times, respectively, greater than those of adults without liver disease. For example, 47% patients with common variable immune deficiency were found to have infection with Giardia, Campylobacter, or Salmonella spp. Symptom complexes may be classified as nausea and vomiting, noninflammatory diarrhea, inflammatory diarrhea, neurologic symptoms, and systemic or miscellaneous symptoms (see Table 111. The percentage of outbreaks for which an etiology is confirmed has increased significantly from 40% in 1998 to 67% in 2002 and has remained consistent to the present. In a report from 2015, bacteria were responsible for 54% of foodborne outbreaks, whereas viruses accounted for 38% and the remainder was attributed to parasites and chemicals. In only half of outbreaks is a single-etiology identified, most notably norovirus (37%) and nontyphoidal Salmonella spp. An extensive list of causatve agents has been associated with foodborne illnesses (Table 111. A more severe and often fatal foodborne illness, variably known as enteritis necroticans, darmbrand (German, fire bowels) and pigbel, is caused by C. Microbiology Clostridia are gram-positive, spore-forming, obligate anaerobes that can be found in the normal intestinal flora of humans and animals, and in the soil. In almost every outbreak of clostridial food poisoning, poultry or roasted, boiled, stewed, or steamed meat is the vehicle of infection. Usually, the meat is cooked in bulk so that heat gain and internal pressure are insufficient to kill the spores. The implicated food invariably undergoes a period of inadequate cooling, during which the spores can still germinate. The organism proliferates rapidly at temperatures between 15°C and 50°C, and unless the food is reheated to a very high temperature, it will contain many viable organisms. Although largely preventable with proper food handling, large outbreaks, sometimes with fatal outcome, due to C. Rare fatalities have been recorded in debilitated or hospitalized patients and are usually caused by dehydration. Enteritis Necroticans Enteritis necroticans is a segmental necrotizing infection of the jejunum and ileum caused by the -toxin of C. The -toxin is normally inactivated by trypsin, but when a low-protein diet is consumed and therefore there is decreased activity of trypsin, or with improper cooking techniques, the disease emerges. Similar outbreaks, associated with the consumption of inadequately cooked pork, have been described in Papua New Guinea and referred to as pigbel, referring to abdominal pain after a pig feast. Fibrin thrombi that occlude superficial arteries and veins of the lamina propria and submucosa are characteristic of this condition, and animal studies suggest that vascular thrombosis initiates the intestinal necrosis typical of C. Microbiology More than 20 staphylococcal enterotoxins have been described, all of which have superantigenic activity and thus cause nonspecific activation of T cells resulting in massive cytokine release. The enterotoxin is composed of 220 to 240 amino acids and ranges in size from 22 to 28 kD. Toxins have significant sequence variability but, when folded, have similar 3-dimensional structure. Epidemiology Staphylococcal food poisoning has a short incubation period of about 3 hours, with a range of 1 to 6 hours, because the disease is caused by ingestion of preformed toxin. The disease usually is clustered within a family or group and has a high attack rate. Transmission of toxin is typically from food handlers who are carriers of toxin-producing strains of S. Diagnosis is based on the typical presentation occurring a few hours following the ingestion of typical foods. Most people with staphylococcal food poisoning do not consult a physician, but more severe cases may require supportive care, particularly rehydration and correction of alkalosis.

The most common helminthic infections are with Strongyloides stercoralis and Paracapillaria philippinensis prehypertension food cheap 180 mg cardizem overnight delivery. Infection with the human T-lymphotropic virus-1 is associated with persistent Strongyloides infection and chronic diarrhea. Diarrhea may be intermittent or persistent, and steatorrhea, anemia, and hypoproteinemia are common. Small bowel series can show changes suggesting mucosal infiltration and ulceration in the duodenum and jejunum. Diagnosis usually is made by examination of multiple samples of feces for the characteristic larvae, although occasionally the infection is only recognized upon small bowel biopsy. Intestinal capillariasis causes a malabsorption syndrome and is common in Southeast Asia, especially Thailand and the Philippines, but is now reported from other countries including Taiwan, Korea, India, Iran, and Egypt. Intestinal capillariasis is associated with protein-losing enteropathy as well as malabsorption of fat and d-xylose. Hymenolepis nana (the dwarf tapeworm) is another helminth increasingly identified in children and adults with diarrhea in tropical countries. Fungal Infections Microsporidiosis has been described in many countries in Asia, tropical Africa, and Central and South America; its therapy in symptomatic persons depends on the infecting species. Diarrhea and malabsorption require specific therapy of the opportunistic infection as well as antiretroviral therapy. Selective IgA deficiency also may be associated with a flat mucosa and giardiasis. Bacterial colonization of the upper small intestine occurs in some patients with primary immunodeficiency and causes malabsorption, that responds quickly to treatment with tetracycline or other antibiotics. In view of the increasing incidence of Crohn disease in tropical countries, it is advisable to document complete resolution of the abnormalities detected at initial investigation after completion of therapy (see Chapter 110). Abdominal pain is usually a significant complaint, accompanied by weight loss and nutritional deficiencies. The disease progresses over several years from a relatively benign infiltration of the entire small intestinal mucosa (stage A) to the development of lymphoplasmacytic and immunoblastic lymphoma (stage C). In patients with stage A disease diagnosed by mucosal biopsy, it is advisable to perform laparoscopy or laparotomy with fullthickness biopsy of the intestine to exclude transmural lymphoma before commencing antibiotic therapy to prevent intestinal perforation with treatment. Areas of bulky tumor also are resected before chemotherapy and biopsy of enlarged mesenteric nodes is performed. In the premalignant stage A, long-term therapy with antibiotics such as tetracycline can cure the disease. In the more advanced stages of the disease (B and C), chemotherapy or total abdominal irradiation are used (see Chapter 41). About a third of patients have small intestinal involvement, and this can reduce the absorptive surface area; extensive small bowel resections ultimately have the same effect. Celiac Disease Celiac disease (gluten-sensitive enteropathy), hitherto considered uncommon in the tropics, is increasingly described from northern India and selected areas of sub-Saharan Africa32 and may be unmasked by intestinal infection. The disease often manifests in infancy around the time of weaning, but presentation at later ages, including adulthood, is not uncommon. Diagnosis is confirmed by the presence of IgA anti-endomysial and antitissue transglutaminase antibodies, although these tests may be negative in persons with selective IgA deficiency. Clinical and histologic responses to gluten withdrawal are important in confirming the diagnosis. Tropical Pancreatitis Idiopathic chronic calcific pancreatitis or tropical pancreatitis is endemic in several tropical regions including the Indian subcontinent and southern Africa. Symptoms of recurrent abdominal pain typically develop in childhood or adolescence and often persist for 8 to 10 years. Exocrine pancreatic insufficiency, with a history of passing oil in the stool, eventually develops in more than 25%, and diabetes mellitus develops in more than 50% of affected patients. The disease is likely to be genetically determined, and both disease-inducing and disease-protective mutations have been noted. Pancreatic enzymes with a high lipase content usually are administered with each meal and are most effective when ingested about halfway through the meal. Therapy of the pain in this disease includes administration of pancreatic enzymes, celiac plexus block, endoscopic removal of calculi, and surgery with pancreatic drainage (see Chapter 59). Panel C is a Masson trichrome stain showing microsporidia which are much smaller (1 to 2 microns) in diameter. Stool samples are examined by microscopy of wet smears, directly and after concentration (sedimentation and flotation) techniques for ova and cysts, and with special (trichrome and/ or modified acid-fast) stains for coccidian parasites.

The inflammatory responses that follow can serve to protect the host or pulse pressure under 40 cardizem 180 mg purchase on line, conversely, contribute to disease development. Members of the commensal microbiota, as well as potential enteric pathogens, can initiate specific mucosal immune responses. Studies of these mucosal immune mechanisms have provided abundant and evolving insights into the complexity of host immune responses. Impaired intestinal motility in the setting of enteric infections, as well as hormones and molecules produced by the host, are known to influence disease severity. This is arguably best illustrated by the marked clinical responses of recurrent C. Finally, emerging data from human and murine models are beginning to uncover ways in which host genetics and diet, functioning by microbiota-dependent and -independent mechanisms, change host susceptibility to intestinal infections.

Bacterial Factors Bacterial pathogens have evolved various virulence factors and mechanisms that enable them to overcome host defenses, including adherence factors, enterotoxin and cytotoxin elaboration, and mucosal invasion among others. Numerous adhesins that differ in morphologic features and receptor specificities have been identified and vary in their capacity to mediate colonization in human compared with animal hosts. The complexity of adherence mechanisms is enhanced by the observation that particular bacteria express and use more than 1 adhesin, a redundancy that likely enhances bacterial virulence. Many bacterial adhesins recognize oligosaccharide residues of glycoproteins or glycolipids displayed in the mucus or surface of intestinal epithelial cells. These adhesins bind to specific receptor sites on the surface of the intestinal cell via specific ligand-receptor interactions. Soft, easily digestible foods such as soups, bananas, mashed potatoes, and rice are helpful. Clostridioides difficile toxin B testing is suggested when risk factors (most commonly antibiotic exposure and/or inpatient or outpatient health care exposure) are present. Nonetheless, asymptomatic colonization by enteric pathogens known to produce toxins and other virulence factors is common. Enteric toxins can be classified by their functional effect on the intestinal epithelium or by their precise molecular mechanism of action. The predominant site of action of most enterotoxins is thought to be the small intestine. Although the biologic activity of many potential enteric bacterial toxins has been abundantly identified, precise molecular mechanisms of action have been identified for relatively few. Other mechanisms likely contributing to induction of disease by enteric bacterial toxins include alteration of epithelial cell calcium signaling and changes in arachidonic acid metabolism among others. Ultimately, proof of the role of a particular enteric bacterial toxin in human disease is via volunteer studies and is infrequent. Examples of enteric bacteria and their toxins studied in humans include Vibrio cholerae, Shigella spp. Shigella species, Salmonella species, Campylobacter jejuni, Yersinia enterocolitica, and some (enteroinvasive) strains of E. Although the colon is most often the primary site of pathology with invasive enteric bacteria, non-dysenteriae Shigella spp. Subsequent colon colonization and cellular invasion by nondysenteriae Shigella spp. The initial step in the diagnostic evaluation of a patient with acute diarrhea is a thorough history and physical examination, the goals of which are to identify patients who may be at risk of severe illness or susceptible to complications, and to identify risk factors for infection and those who will benefit from specific therapy. Patients who are debilitated, malnourished, or immunocompromised, and those who have severe comorbid illnesses, are at increased risk for complications of diarrhea and infection. The morbidity and mortality of infectious diarrheal diseases are highest in children younger than 5 years of age (particularly severe in those <2 years old28) and older adults. These high-risk patient groups may require hospitalization for diagnosis and treatment.

A venous hum may be heard in the epigastrium in a patient with portal hypertension and represents collateral flow in the falciform ligament pulse pressure by age order cardizem. Laboratory studies frequently reveal evidence of hepatic synthetic dysfunction, including prolongation of the prothrombin time, hypoalbuminemia, and hyperbilirubinemia, as well as anemia. Thrombocytopenia and leukopenia, reflecting hypersplenism and, in alcoholics, bone marrow suppression, may be noted. Patients with severe bleeding may present with hypovolemic shock and renal insufficiency. Abdominal imaging studies frequently reveal splenomegaly, collateral vessels, abnormal liver echotexture and contour, and ascites. Vasopressin and Its Analogs Vasopressin is an endogenous peptide hormone that causes splanchnic vasoconstriction, reduces portal venous inflow, and decreases portal pressure. By causing constriction of systemic vessels, vasopressin may result in necrosis of the bowel. Additionally, vasopressin has direct negative inotropic and chronotropic effects on the myocardium that lead to reduced cardiac output and bradycardia, respectively. An increase in cardiac afterload can result in myocardial infarction, and antidiuresis, resulting from the action of vasopressin on the kidney, can result in hyponatremia. Terlipressin, or triglycyl-lysine-vasopressin, is a semisynthetic analog of vasopressin that is cleaved by endothelial peptidases to release lysine vasopressin. Compared with vasopressin, terlipressin is associated with lower circulatory levels of the vasopressin analog and a lower rate of systemic side effects. Vasopressin and terlipressin have been used in combination with nitrates to decrease the risk of systemic side effects. Terlipressin is preferred over vasopressin because of its superior safety profile. In addition, an increase in survival has been demonstrated in patients with variceal bleeding treated with terlipressin. Treatment also may be directed at the varices with use of endoscopic or radiologic techniques. Following a single 250-g bolus injection of somatostatin, portal and azygos blood flow decrease, but the effect lasts only a few minutes. Somatostatin also decreases portal pressure by decreasing postprandial splanchnic blood flow. Moreover, continuous infusion of octreotide does not decrease portal pressure despite decreasing the postprandial increase in portal pressure. Also, early administration of vapreotide may be associated with improved control of bleeding, but without a significant reduction in mortality rate. Pharmacologic Therapy the pharmacologic agents used in the treatment of portal hypertension are divided into 2 groups: those that decrease splanchnic blood flow and those that decrease intrahepatic vascular resistance (Box 92. The agents that decrease splanchnic blood flow acutely are vasopressin and its analogs and somatostatin and its analogs. Agents that target intrahepatic vascular resistance include -adrenergic blocking agents, angiotensin receptor blocking agents, and nitrates, but only carvedilol and nitrates are now considered for clinical use. Diuretics, by decreasing plasma volume, may reduce portal pressure but are not recommended if the patient does not have ascites. Prokinetic agents may decrease intravariceal pressure by contracting the lower esophageal sphincter but have not been evaluated in clinical trials. Blockade of 2-adrenergic receptors, which cause vasodilatation in the mesenteric circulation, allows unopposed action of 1-adrenergic receptors and results in decreased portal flow. The combination of decreased cardiac output and decreased portal flow leads to a decrease in portal pressure. Despite adequate 1-adrenergic receptor blockade, some patients may benefit from a further increase in the dose of beta blocker to increase the degree of 2-adrenergic blockade. Raising the dose, however, results in more side effects and the likelihood that treatment will need to be withdrawn. A meta-analysis, however, concluded that use of nonselective beta blockers was not associated with a significant increase in all-cause mortality in patients with cirrhosis and either controlled ascites or refractory ascites. The meta-analysis does not support the position that nonselective beta blockers should routinely be withheld from all patients with ascites. The vasodilatation results from a decrease in intracellular calcium in vascular smooth muscle cells. Nitrates cause venodilatation, rather than arterial dilatation, and decrease portal pressure predominantly by decreasing portal venous blood flow.
