The study found that the primary outcome of persistent or recurrent pericarditis occurred in 37. Colchicine also reduced the rate of symptom persistence at 72 hours, reduced the rate of hospitalization, and increased the rate of remission at 1 week. Twentyone patients who initially responded to a 2-month course of anakinra were randomized to continue daily subcutaneous drug (n = 11) or switch to placebo (n = 10) for 6 months or until a recurrence of pericarditis. Pericarditis recurred in 9 of 10 placebo patients and 2 of 11 patients continued on anakinra (P <. In a similar trial in patients with active tuberculous constrictive pericarditis, the addition of prednisolone increased the rate of clinical improvement. Early surgical intervention is advocated in patients with hemodynamic compromise from recurrent effusion or progressive pericardial thickening. Pericardiectomy frequently results in striking hemodynamic improvement, but if diagnosis and therapy have been delayed, myocardial function may be affected, leading to less satisfactory results.

Fluid Analysis Diagnosis · Community-acquired pneumonia is the most common predisposing condition to pleural infection. Symptoms in addition to those related to the pneumonia may include chest pain and splinting on the affected side, but symptoms and signs are both insensitive and nonspecific. Conventional chest x-rays may be insensitive for effusions, which occur in >40% of cases of community-acquired pneumonia. Transudates are characteristic of noninfectious processes such as congestive heart failure, but occasionally occur early in the course of parapneumonic effusion and may respond to medical therapy alone. Tuberculosis is the exception, since most tuberculous effusion is exudative but resolves spontaneously even without treatment. Low pH is a strong predictor of the need for aggressive drainage of a parapneumonic effusion and requires submission for testing in a closed syringe like a blood gas. Streptococcus pneumoniae remains an important cause of community-acquired bacterial pneumonia and pleural disease. Members of the Streptococcus anginosus group are important empyema pathogens but infrequent causes of pneumonia. In that context, methicillin-resistant Staphylococcus aureus, gram-negative organisms, and anaerobic upper aerodigestive tract organisms predominate. Effusions that require drainage almost always require placement of a chest tube (tube thoracostomy). Additional surgical measures are often necessary, especially when bronchopleural fistula is present. The pulse of fluid (hydrostatic pressure) is accompanied by osmotic pressure between the vessels in the parietal pleura and the 914 pleural space. The outflow of fluid is in a dependent direction through lymphatic stomata in the lower parietal pleura. The pleura itself consists of collagen and elastic fibers that contain interspersed mesothelial cells. These are metabolically active and mediate some portion of the inflammatory response, as well as provide part of the barrier function of the pleura. Macrophages are the predominant cell (75%), followed by lymphocytes (23%) and mesothelial cells (1%). Uncomplicated effusions usually 915 respond to measures directed at their cause, for instance, treatment of a pneumonia accompanied by a parapneumonic effusion. Complicated effusions represent a middle point, with the development of fibrinous material over time that will cause septations and loculation of the fluid if the cause is not successfully addressed. Complicated effusions and empyema are likely to require drainage and therapy directed at the pleural complication itself. Pleural fluid is a transudate when it is primarily influenced by changes in hydrostatic pressure in heart failure and fluid overload states such as renal failure or cirrhosis. Exudates are characteristic of effusions associated with cancer, infection, and many noninfectious causes, as further discussed in "Fluid Analysis" (see later). It is important to note that empyema is still defined as fluid that is purulent or has positive microbiologic studies. For parapneumonic effusion, the risk for outcome associated with pleural space anatomy, pleural fluid bacteriology, and pleural fluid chemistry yielded a four-category assessment as documented in a 2000 statement from the American College of Chest Physicians. Staphylococcal peptidoglycan induces the production of -defensins in a murine model, and signaling cascade antagonists interfere with this. Bacille Calmette-Guérin, in an in vitro model, decreases the tight junction between cells by downregulating -catenin, an adherens junction protein. Interferon- in particular is elevated in the pleural fluid of patients with tuberculosis. In animal models, blocking transforming growth factor- with an antibody decreases purulence and fibrosis. This important in vitro observation supported clinical trials of fibrinolytics in the treatment of pleural effusion, as delineated later. In some of these, there are sufficient descriptions of the likelihood and character of the effusion to increase diagnostic certainty. Cancers, generally secondary but occasionally primary in the pleura, with mesothelioma prominent among them, are common causes of exudative effusion. Of note, immune checkpoint inhibitors, while associated with pneumonitis, are rarely if ever the causes of pleural effusion. Thus an effusion in the context of these therapies requires investigation for potential infectious causes. The epidemiology of infectious pleural effusion is influenced by the rigor of attempts to detect effusions, the era reported, the age of the population studied, and the prevalence of tuberculosis and other endemic diseases. The outcome of bacterial pleural disease is heavily influenced by the success of treating an associated bacterial pneumonia. In a pediatric hospital in the United States, temporal trends from before and through the initial years of the antibiotic era show a drop in empyema from 1934 to 1958, with decreases in cases caused by Haemophilus influenzae, streptococci, and pneumococci but a rise in S. As disease caused by antibiotic-susceptible organisms decreased, mortality associated with empyema increased, as did the age of the population affected. Improvements in antibiotic therapy may have been responsible for shorter hospitalizations in the later years compared to those in the preantibiotic era. In children, Streptococcus pneumoniae and Streptococcus pyogenes were the most frequent causes of secondary bacterial pneumonia in the 2009 influenza A(H1N1) epidemic. Decreases in tuberculosis in Europe and the United States have not occurred to the same extent elsewhere. Tuberculous effusion accounted for 49 of 100 effusions in a series from Malaysia in 1991. The consequences of an infected pleural effusion depend on the population, on the infection, and, critically, on the vigor with which the physician makes the diagnosis and chooses the right therapy. Most tuberculous effusion (see below) is a low-mortality disease and remits even without therapy, but treatment decreases the likelihood of further tuberculous disease. Only 36% of patients were appropriately assessed, and the authors commented on the poor adherence to recommended diagnostic approaches in both emergency rooms and internal medicine wards. Outcome was related to delays in drainage, with patients with the most severe disease (requiring decortication) suffering the highest mortality when the procedure was delayed. Ninety percent of those deemed eligible for thoracocentesis alone were cured, but chest tube therapy alone (closed thoracostomy) was successful in only 62% and had a mortality of 11% in 90 patients, with second procedures needed in 24 cases. There were medical failures (need to proceed to surgery) in 15%, and the absence of purulence predicted medical success but the presence of purulence did not predict failure. In the United States, pleural disease was found to be secondary only to lymphadenitis in extrapulmonary cases from 1993 to 2006. Because of its remitting nature and the difficulty of microbiologic diagnosis when only pleural fluid is sampled, pleural tuberculosis in the early 20th century was not uniformly considered tuberculous disease, but was followed by pulmonary/extrapulmonary tuberculosis in 34.

F Intraabdominal Infections 74 Definition Peritonitis and Intraperitoneal Abscesses Larry M. Complicated infections involve extension beyond the organ, either localized or generalized peritonitis, with spillage of microorganisms into the sterile peritoneal space. Community-acquired infections may be further subdivided into low- or high-risk infections depending on the probability of involvement of drug-resistant bacteria and severity of infection (mild, moderate, severe), together with any significant comorbidities the patient may have. Microbiology Diagnosis · Primary peritonitis is diagnosed by excluding a primary source of intraabdominal infection. Prevention Therapy · Pending confirmatory studies, empirical antibiotic therapy for suspected primary peritonitis should be initiated (see Table 74. Intraabdominal infections can take several forms and include a variety of entities resulting from disease or trauma to both hollow and solid organs located in either the peritoneal cavity or retroperitoneal space. Although the gastrointestinal tract is most commonly involved, the urinary and gynecologic tracts may also serve as the primary source of infection. Intraperitoneal abscesses may form in dependent recesses, such as the pelvic space or Morison pouch; in the various perihepatic spaces; within the lesser sac; or along the major routes of communication between intraperitoneal recesses, such as the right paracolic gutter. In addition, infection may be contained within the intraabdominal viscera, as in hepatic, pancreatic, splenic, tubo-ovarian, or renal abscesses. Abscesses also frequently form around diseased viscera (pericholecystic, periappendiceal, pericolic, and tubo-ovarian) and between adjacent loops of bowel. In addition, intraabdominal infections are classified according to whether the infection is community acquired (approximately 80%) or health care associated. Moreover, community-acquired infections may be further subdivided into low- or high-risk infections depending on the probability of the presence of drug-resistant bacteria, severity of infection (mild, moderate, severe), and any significant patient comorbidities. These categories help to assist in the management of the patient, selection of antimicrobial therapy, and prediction of outcomes; health care­associated infections are most commonly acquired as complications of previous elective or emergency intraabdominal operations. These are caused by nosocomial isolates particular to the site of the operation and to the specific hospital and unit, all of which possess an increased probability of the presence of antimicrobial-resistant pathogens and bacterial species and fungi not common to the intraabdominal cavity. Intraabdominal infections also can be categorized as uncomplicated or complicated. Although the distinction is not always clear, complicated intraabdominal infections historically have been defined as extending beyond the hollow viscus of origin into the peritoneal space, with associated abscess formation or peritonitis, whereas those referred to as uncomplicated generally involve intramural inflammation of the gastrointestinal tract or a single organ but have a substantial likelihood of advancing to complicated disease if not properly treated. In women, the peritoneal cavity is perforated by the free ends of the fallopian tubes. The stomach, jejunum, ileum, cecum, appendix, transverse and sigmoid colons, liver, gallbladder, and spleen lie within the peritoneal cavity, some being suspended by a mesentery. The transverse mesocolon divides the peritoneal cavity horizontally into an upper and a lower space. The peritoneal cavity extends from the undersurface of the diaphragm to the floor of the pelvis. The peritoneal cavity has several recesses into which exudate may become loculated.

Tens of millions in the United States have gallstones; 1% to 3% are complicated by acute cholecystitis. Between 2% and 15% of cases occur without gallstones, known as "acalculous cholecystitis. Diagnosis · Symptoms are often nonspecific, and a high index of suspicion is required. For pyogenic liver abscesses, it is often coupled with diagnostic/therapeutic aspiration. Microbiology Therapy Epidemiology · An estimated 1 to 4 cases of pyogenic liver abscess occur per 100,000 persons each year. Amebic liver abscess represents a distinct clinical entity caused by invasive Entamoeba histolytica infection. It has a distinct pathogenesis that is characterized by the specific induction of hepatocyte apoptosis by the organism. Pyogenic liver abscess, by contrast, does not represent a specific liver disease but is the end result of a number of pathologic processes that cause a suppurative infection of the liver parenchyma.
