Several drugs can be used as the third agent, including rifabutin (300 mg/day), ciprofloxacin (50050 mg/day), and amikacin (15 mg/kg/day). The choice of the third agent depends on the severity of the illness, drug interactions, hepatic and renal function, patient tolerability, patient compliance, and cost. The results of early, uncontrolled trials were disappointing, with poor microbiologic response rates, little improvement in clinical symptoms, and a high incidence of adverse drug reactions. In another investigation, all isolates initially were susceptible to clarithromycin, but after 12 weeks of monotherapy (1 g/day), in vitro resistance developed in 16 of 72 (22%) patients. Subsequently, the rifabutin dosage was lowered to 300 mg/day, and the incidence of uveitis decreased to 5. Although clearance of bacteremia was superior at the higher rifabutin dose, no differences in survival were observed. Several recent studies have demonstrated no bacteriologic or clinical benefit with the addition of clofazimine. Survival was found to be significantly decreased in the clofazimine arm; 61% of the patients died versus 38% in the two-drug arm. Other considerations for the addition of a third-line agent include the severity of the illness, potential drug interactions, tolerability, hepatic and renal function, and cost. Clinical improvement may not be observed for 2 to 4 weeks, whereas eradication of bacteremia frequently takes longer (42 weeks). If no improvement in clinical manifestations is observed in 4 to 8 weeks, a mycobacterial blood culture should be repeated along with susceptibility testing. If resistance is observed or suspected, two new drugs should be added based on susceptibility testing with or without the macrolide. If the organism is found to be susceptible to macrolides, therapy should be continued and adherence, absorption, tolerance, and drug interactions should be considered. In some cases, drug doses need to be modified or alternative drugs selected to prevent adverse events or therapeutic failures (Table 70-11). Although the combination of azithromycin and rifabutin is more effective than azithromycin alone, the increased cost, adverse events, potential for drug interactions, and absence of a survival benefit preclude this regimen from being routinely recommended. If neither clarithromycin nor azithromycin is tolerated, rifabutin 300 mg/day may be used48 (Tables 70-2 and 70-12). Before the use of macrolides, rifabutin was the agent of choice for primary prophylaxis. However, no survival benefit has been demonstrated with the use of this agent, and the drug is associated with high cost, complex drug interactions, and an increased risk for uveitis. Significantly more patients in the clarithromycin arm survived during the 10-month follow-up (68% versus 59%), with an accompanying longer median duration of survival. Time to death was not significantly different among the treatments; however, the combination arm had an increased incidence of adverse drug effects. Time to death was not significantly different among the arms, but the combination was more toxic. The decision to use clarithromycin or azithromycin (both first-line recommendations for primary prophylaxis) is based on patient compliance and the potential for drug interactions. Azithromycin (1,200 mg once weekly) may be preferable for a patient who has difficulty with compliance. In contrast with clarithromycin, azithromycin does not affect the cytochrome P450 enzyme system and is therefore less likely to interact with other drugs. Bacteria can also be associated with chronic diarrhea, primarily Salmonella, Shigella, C. Fungal Infections In acute infectious diarrhea, fungal infections are rare; they tend to be isolated to the oropharynx and esophagus and are predominantly caused by Candida species, primarily C. However, patients with disseminated histoplasmosis may develop diarrhea (Table 70-12). Although not usually associated with diarrhea, proctitis may result in bloody, mucousy stools. She reports two or three watery, unformed bowel movements per day for approximately 6 weeks, with accompanying abdominal pain. Enteric infections can be caused by fungal, viral, bacterial, or protozoan pathogens. Acute diarrhea is defined as "greater than or equal to three loose or watery stools for >10 days with fever, blood in the stool, and/or weight loss. Acute diarrhea is usually associated with bacterial causes, such as Salmonella, Shigella, Campylobacter jejunii, or Clostridium difficile.

Their pain was controlled; arrhythmic complications were treated; and bed rest, nitrates, and -blockers minimized the amount of oxygen required by the heart. Damage to the plaque results in blood being exposed to collagen and fatty acids; this in turn activates platelets, the first step in thrombosis and formation of a fibrin clot. In the past, patients with Q-wave infarctions were generally believed to have more extensive necrosis and a higher in-hospital mortality rate. Patients with a non-wave infarct were believed to have a greater likelihood of experiencing postinfarction angina and early reinfarction. An anterior wall infarction carries a worse prognosis than an inferior or lateral wall infarction. Patients may complain of prolonged substernal chest pain or pressure, shortness of breath, diaphoresis, nausea, and vomiting. The pain might be described as burning, and it may occur in the arms, shoulder, neck, jaw, or back. Men commonly complain of chest pain, whereas women present with nausea and diaphorsis. Signs of severe left ventricular or right ventricular dysfunction may be present (see Chapter 19). The patient may have severe hypertension due to pain or, conversely, may be hypotensive. Significant tachycardia (heart rate >120 beats/minute) suggests a large area of damage. On cardiac auscultation, a fourth heart sound (S4) may be heard, denoting an ischemia-induced decrease in left ventricular compliance. Patients with a history of cerebrovascular disease may not be eligible for thrombolytic therapy. Peripheral pulses should be examined to assess perfusion and to obtain a baseline before invasive procedures are instituted. Thrombolytic therapy is not beneficial in these patients and is a major point of differentiation. It can appear in the serum within 3 to 6 hours after myocardial damage, and levels generally peak in 12 to 24 hours. The continuous monitoring of patients in a coronary care unit has reduced the in-hospital mortality rate related to ventricular arrhythmias. Large clinical trials have proven that administration of a thrombolytic agent reduces mortality. It binds to plasminogen to form an active plasminogento-streptokinase complex that cleaves other molecules of plasminogen to form plasmin. Plasmin, which is an active fibrinolytic enzyme, then acts on a fibrin clot to enhance its dissolution. Anistreplase, also known as anisoylated plasminogen streptokinase activator complex, is a combination of streptokinase and plasminogen with an anisoyl group reversibly placed within the catalytic center of the plasminogen moiety. As a result of decreased cardiac output and decreased perfusion pressure associated with left ventricular dysfunction, a number of compensatory mechanisms become activated. The levels of circulating catecholamines increase in an attempt to increase contractility and restore normal perfusion. In addition, the renin-angiotensin-aldosterone system is enhanced, leading to an increase in systemic vascular resistance and sodium and water retention. These compensatory mechanisms can eventually worsen the imbalance between myocardial oxygen supply and consumption by increasing the myocardial oxygen demand.
