Pathogenesis Multiple poorly understood mechanisms may contribute to the pathogenesis heart attack prevention order generic carvedilol on-line. The finding is not disease-specific since any necrotizing arteritis as well as other entities can produce aneurysms blood pressure pulse 12.5 mg carvedilol purchase amex. Extracranial branches of the aortic arch are reportedly involved in 10:15% of cases heart attack grill locations best order for carvedilol. This high magnification image shows inflammatory cell destruction of an elastic layer (arrow) blood pressure chart good and bad best order carvedilol. Less common manifestations are related to the central or peripheral nervous systems arrhythmia update 2010 order cheap carvedilol on-line, the respiratory tract and extra-cranial large-vessel involvement. Additional reports127,392,393 showed isolated granulomatous pulmonary giant cell arteritis without systemic vascular involvement. Arteritis is most commonly found in the arteries arising from the aorta, particularly the superficial temporal, ophthalmic, posterior ciliary and vertebral arteries. Depending on the extent of the arterial obliteration and on the anatomy Pathogenesis Peak disease rates occurring every 5 to 7 years suggests a possible infectious cause or trigger. Epidemiology Takayasu arteritis is relatively rare, but most commonly seen in Japan, Korea, China, South East Asia, India and Mexico. In 1990, it was included in the list of intractable diseases maintained by the Japanese government,413 and to date more than 5000 patients have been registered. Although it has been estimated that 150 new cases are diagnosed in Japan yearly, the incidence in Europe and the United States is no more than three new cases per year per million population per year. Because pulmonary arteries affected are usually large elastic-type arteries, it is reasonable to regard isolated pulmonary arterial disease as a manifestation of Takayasu arteritis (see Table 13). Disseminated visceral giant cell arteritis is very rare but is reported to involve the pulmonary arteries. It may be that the epitopes are more important as a disease susceptibility factor than the allele in which they are found. Takayasu arteritis Introduction Takayasu arteritis is a primary arteritis of unknown cause that commonly affects the thoracic and abdominal aortas and their major branches, including the pulmonary artery. Manifestations range from non-palpable pulses and vascular bruits to catastrophic neurological disorders. Nonspecific clinical features include fever, night sweats, malaise, weight 747 Chapter 19: Pulmonary vasculitis and pulmonary hemorrhage syndromes loss, arthralgia and myalgia. Characteristic signs and symptoms include diminished or absent pulses associated with limb claudication and blood pressure discrepancies between the arms. Neurological features are also described, but the frequency with which Takayasu arteritis involves the brain parenchyma is not clear. Pulmonary artery involvement is reported in 14:100% of patients, depending on the method used to examine the pulmonary artery. Pulmonary artery disease shows little correlation with the systemic pattern of arterial involvement,406,422,423and is rarely the presenting manifestation. In the granulomatous phase, the media is infiltrated by lymphocytes and occasional giant cells with neovascularization and loss of elastic fibers. Inflammation is most prominent in the adventitia, with possibly nodular collections of B- and T-lymphocytes and dendritic cells. In the chronic phase there is fibrosis with destruction of remaining elastic tissue. A great proportion of infiltrating mononuclear cells are gamma delta T lymphocytes. This finding is mirrored in ventilation perfusion scans where multiple perfusion defects may be noted. Coarctation of the aorta and Marfan syndrome are also considerations (see Chapter 11). In a study of 280 patients identified through the American College of Rheumatology Vasculitis Criteria Databank: 217 of whom had giant cell arteritis and 63 of whom had Takayasu arteritis: an age of disease onset before the age of 40 was the single most helpful factor in identifying Takayasu arteritis (see Table 13). If disease progression is slow, the affected arterial wall loses the medial layer, fibrosis progresses and the lumen usually becomes narrow in a patchy distribution. If disease progression is rapid, fibrosis can be incomplete with subsequent dilatation and aneurysm formation. The intima may be ridged, with a "tree bark" appearance, a feature common to many aortitides. In Prognosis and natural history Takayasu arteritis is a chronic disease with exacerbations and remissions over time. Complications such as 748 Chapter 19: Pulmonary vasculitis and pulmonary hemorrhage syndromes Table 14 Behçet syndrome: International Study Group diagnostic criteria retinopathy, hypertension or aortic regurgitation and progression suggest a 66% 15 year-survival as compared with those well controlled with medical therapy, who have over 90% 15-year survival. There may be uncertainty with regard to the onset and course of the disease, a poor correlation between clinical assessment and disease activity, poor disease activity markers in peripheral blood, and a lack of useful treatment in up to 25% of patients with progressive disease. The risk of increased morbidity and mortality means most patients who present will ultimately receive immunosuppression in addition to corticosteroids. Early treatment of those with complicated, progressive disease may lead to a better prognosis for this group since steroids are only palliative, with a high incidence of recurrences. Percutaneous transluminal angioplasty or bypass grafts may be indicated in attempts to reverse vascular obstruction and ischemic symptoms. While vascular stenosis is common, aneurysm rupture, with all its morbidity and mortality, is rare. As inflammation is a risk factor for atherosclerosis, significant atherosclerotic complications are likely in the long term. Hulusi Behçet, a Turkish dermatologist, wrote the first scientific description of this disease in 1937. Thus, the diagnosis is made on the basis of criteria proposed by the International Study Group in 1990 (see Table 14). Thus, cases of the disease cluster along the ancient Silk Road, which extends from far eastern Asia to the Mediterranean basin (see Table 15). The prevalence rate ranges from 2 to 30 cases per 100 000 persons in other Asian countries, but is very low in Europe and North America. The male to female ratio is approximately equal in regions where the disease is more common, but women are affected more often in the United States and northern Europe. Clinical manifestations Clinical manifestations include involvement of the skin, central nervous system, gastrointestinal and genitourinary tracts and the lung. Subcutaneous thrombophlebitis, deep vein thrombosis, epididymitis, arterial occlusion, aneurysms, arthralgia, arthritis and renal disorders are also observed (see Table 16). Pulmonary symptoms include hemoptysis, dyspnea, cough and chest pain along with general fatigue. This lesion most frequently involves the right lower lobe lobar arteries, followed by the right and left main pulmonary arteries. Pulmonary parenchyma disorders include atelectasis, pulmonary hemorrhage and/or infarcts. Other thoracic disorders include occlusion of the superior vena cava and thrombosis of the innominate and subclavian veins. Clinical observations and laboratory investigations support the concept that immunological mechanisms induced by microbial pathogens occur in genetically susceptible individuals. The example is the skin pathergy reaction in which a papule or pustule occurs following a simple needle prick to the skin, similar to those appearing spontaneously in the disease. Pleural involvement features a proliferation of small collateral blood vessels within the wall of the destroyed artery (not shown). Pulmonary infarcts, eosinophilic pneumonia, diffuse alveolar hemorrhage, diffuse alveolar damage and fibrinous pleuritis have been reported. Pulmonary arterial aneurysm appears to be associated with a particularly poor prognosis. Particular organ manifestations can be treated with different agents including but not limited to colchicine, steroids, azathioprine, cyclophosphamide, cyclosporin, infliximab and etanercept. Large artery involvement is best treated with steroids along with another immunosuppressive agent and perhaps anticoagulation.

Only a sound understanding of the complex epidemiological, etiological, and molecular-pathological aspects of lung carcinoma will enable clinical and scientific progress against this deadly disease, regardless of technological advances. This chapter aims to elucidate the epidemiological, etiological and clinical aspects of lung cancer. Epidemiology Incidence and mortality Lung cancer is the most common and deadliest cancer in the world. The worldwide incidence of lung carcinoma in 2008 reached 1 608 823 cases, representing 12. Standardization is necessary when comparing several populations that differ with respect to age. The total burden of lung cancer is slightly greater in less well-developed countries, compared to more developed regions. Approximately 15% of the global lung cancer cases in men and 53% in women do not appear to be caused by smoking. In global terms, for men and women combined, lung cancer in never-smokers ranks in seventh place, after cancer of the lung due to smoking, and cancers of the stomach, colon:rectum, liver, breast and esophagus. In the same year developing nations, including China, reported 883 000 new cases and 778 000 deaths. In China about half of the male population smokes, and 70% of the households use solid fuels (wood, crop residues and coal) for heating and cooking. These two diseases account for a significant proportion of deaths from these diseases in developing countries. In patients with previous primary head and neck cancer, subsequent lung cancer contributes to the highest proportion of the second primary cancers, with a 20-year cumulative risk of 13%. The lowest rates are observed in southern Asia and sub-Saharan Africa, at least in part due to poor data collection. This decline is related to the reduction in smoking, especially in the older generations. With 300 million current male smokers, lung cancer will soon be responsible for more than 2 million deaths per year in Chinese men. The smoking prevalence in American men decreased by nearly 50% from its peak in the 1960s and the death rate in men from lung cancer has decreased slightly. In the same period, the smoking prevalence in American women has only decreased by 25%. This incidence is significantly less than that attributed to breast cancer including in situ carcinoma (192 370). Due to a decline in breast cancer incidence and an increase in lung cancer incidence in women, this order is reversed: more women died in 2008 of lung cancer than of breast cancer. In many developing countries where female smoking is not common, lung cancer rates are very low.

Doran Lung transplantation has evolved over the last 30 years from an experimental procedure to a proven therapeutic intervention for a wide variety of end-stage parenchymal and vascular disorders in infants, children and adults. Guthrie and Carrel first demonstrated the technical feasibility of the method over a century ago in a heterotopic procedure in which the heart and lungs of a kitten were implanted in the neck of a cat. Single lung and double lung (including bilateral sequential single lung procedures) transplant programs became established later in that decade. The living-related lobar transplant program was developed by Starnes and colleagues in the mid-1990s and has more recently been expanded to cadaveric lobar lung transplantation. The unadjusted 1-year, 5-year and 10-year survival figures for adults are 79%, 52% and 29%, respectively. These results have improved incrementally over the years and reflect improvements in surgical techniques, patient selection, perioperative and post-transplant patient management, immunosuppressive regimes, and the detection and treatment of infectious organisms. In the perioperative and postoperative period up to 30 days, primary graft failure, infection, technical and other complications and acute rejection account for the majority of deaths. In the period from 1 month to 1 year, infection and rejection are the most common causes of death. After 1 year chronic airway rejection is the commonest cause of death and remains an indication for retransplantation in some centers. The program has resulted in a significant decline in the wait-list times for patients from years to months and a drop in the number of deaths on the wait-list. Establish the primary native lung diagnosis on transbronchial or open lung/video-assisted thoracoscopic specimen prior to transplant 3. Thoroughly evaluate explanted lung(s) to confirm primary pathological diagnosis and identify additional lung pathologies, such as infection or occult malignancy 4. In post-transplant biopsies, identify etiology of early graft dysfunction such as primary graft dysfunction/ ischemia-reperfusion injury, hyperacute rejection, infection, anastomotic complications 5. Determine efficacy of anti-rejection or anti-infection therapy in followup biopsy specimens 6. Diagnose other causes of graft dysfunction such as aspiration pneumonia, drug toxicity, infection, acute antibodymediated rejection 7. Establish recurrence of primary parenchymal diseases in the allograft such as sarcoidosis, lymphangioleiomyomatosis 10. The explanted lung specimen should be carefully evaluated to establish the primary diagnosis and exclude secondary complications such as infections or occult malignancies. In the perioperative and early postoperative period primary graft failure must be distinguished from hyperacute rejection, severe acute cellular rejection, and infection, as these will be treated differently. In the later post-transplant setting the pathologist is responsible for the diagnosis and grading of acute allograft rejection. As we will discuss in more detail, acute cellular rejection is a diagnosis of exclusion and a variety of morphological mimics must be considered. Following the institution of augmented immunosuppressive therapy for the treatment of allograft rejection, follow-up biopsies are usually performed to determine treatment effect. The diagnosis of chronic airway rejection by transbronchial biopsy can be problematic on account of sampling issues. Finally, the important role of the post-mortem examination for its clinical and educational functions must be emphasized. We attempt to obtain permission for autopsy evaluation of every thoracic transplant recipient and discuss in detail the clinical and pathological findings in the setting of a 768 Chapter 20: the pathology of lung transplantation multidisciplinary conference. It is not uncommon to find clinically significant missed diagnoses in post-mortem studies. In a recent study 21% of autopsy cases found a discrepancy between the autopsy findings and clinically suspected cause of death. Hyperacute rejection, myocardial infarction, pulmonary embolism, high-grade acute cellular rejection and disseminated fungal infection were the most frequently missed diagnoses. Not surprisingly these patients are challenging and often have multiple interrelated clinical problems. The use of noninvasive techniques to monitor the immunological status of cardiac transplant recipients has been established but remains an elusive strategy in lung transplantation. This stems in large part from the poor sensitivity and specificity of clinical signs and symptoms, radiological techniques and functional techniques in distinguishing acute rejection, infection and airway anastomotic complications. As a result the transbronchial biopsy is widely regarded as the "gold standard" for the evaluation of the pulmonary allograft. It should be recognized, however, that there are limitations to this technique that include both technical and interpretative issues. Tissue atelectasis and artifactual distortion are found to varying degrees with every sample. Gentle swirling agitation of the biopsy pieces in formalin fixative can reduce the amount of atelectasis. The liberal use of leveled sections and connective tissue stains can resolve crush artifact and render a biopsy fragment interpretable in some cases. Specifically, a minimum of five pieces of alveolated tissue that are not completely collapsed should be obtained and immediately fixed in a standard fixative such as 10% neutral buffered formalin. In the 1990 and 1996 versions it was recommended that each piece should contain bronchioles and greater than 100 air sacs but this specific requirement was omitted from the 2007 document. Electron microscopy has no role in routine transplant biopsy evaluation but may be part of research protocols. It is important to emphasize that frequently five pieces alone will not be sufficient as one or more piece is composed of airway wall, strips of airway mucosa, blood vessel or thrombus and so generous sampling is encouraged. The histological assessment of transplant pathology requires optimum handling and processing. Overnight processing in an automated processor is optimal but a variety of rapid processing programs are available for handling emergency biopsies or clinically indicated biopsies that yield slides in 3:4 hours. Following embedding in paraffin wax a minimum of three "leveled" sections each with multiple ribbons prepared at 4:5 mm thickness and routinely stained with hematoxylin-eosin (H&E). Additional histochemical stains, immunohistochemistry and molecular techniques are advocated on a case-by-case basis. It can be used for the rapid assessment of infection in a patient with clinical deterioration. The specific methodologies differ among institutions but generally small aliquots of normal saline are put into the airways and then aspirated by manual or mechanical suction. Fractions of the fluid can be sent for microbiological culture, for cytopathological evaluation, a cell count and differential quantitation. The exclusion of bacterial or fungal infection is important in the early postoperative period and in patients with chronic airway rejection. Some centers analyze the functional characteristics of the cells retrieved from the lavage as an adjunct test for infection, as well as acute and chronic rejection. The procedure was found to be most helpful in the early postoperative period for identifying acute rejection or infection. Complications arose in 5:25% of reported cases and ranged from minor issues such as wound infection, postoperative pain and prolonged air-leaks to more serious problems such as respiratory failure and intrathoracic bleeding requiring surgical re-exploration. Importantly, resolution of air-leaks occurred in all patients although in some cases the course was protracted. The results of this small number of studies and our own experience indicate that there are specific clinical indications that warrant consideration for this invasive procedure. A temporal approach to lung transplant pathology Lung transplant pathologists recognize that many of the clinical and pathological issues in the lung allograft occur within a reasonably narrow temporal framework. For example, primary graft failure and its morphological correlate of diffuse alveolar damage occur in the early postoperative period. Acute rejection is uncommon during this early period but is usually identified later in the first year. Obliterative bronchiolitis is uncommon in the first 6 months and typically presents after 1 year. A limited number of studies published in the pediatric and adult transplant populations have shown similar findings. The most common indications were unexplained deteriorating pulmonary dysfunction after thorough clinical, serological and bronchoscopic evaluation, or the onset of new or persistent Perioperative and early post-transplant period (up to 1 month) Complications in the immediate perioperative and early postoperative period may present with similar clinical features and include primary graft dysfunction, hyperacute rejection, pulmonary venous obstruction, acute left ventricular dysfunction and overwhelming pulmonary infection with sepsis. The etiology, treatment and prognosis differ for each and their prompt recognition is important. With the exception of primary graft dysfunction, the other disorders in this group are rare. Perioperative and early post-transplant period (up to 1 month) Primary graft dysfunction/failure Hyperacute rejection Anastomic complications Infections 2. Intermediate complications (1 month: 1 year) Acute cellular rejection Airway inflammation Acute antibody mediated rejection Infections Post-transplant lymphoproliferative disorder Drug toxicity Aspiration changes 3. It exhibits both a clinical and a morphological spectrum which in its severe form is characterized by acute hypoxemic respiratory failure, diffuse pulmonary infiltrates on radiographs and diffuse alveolar damage in lung biopsy specimens. Donor risk factors include older or very young donors, African-American race, female gender, history of smoking, prolonged mechanical ventilation, aspiration episodes, lung trauma and hemodynamic instability after brain death. The mechanisms at the cellular and molecular level are now beginning to be elucidated towards the goal of limiting or eliminating its onset and development. Similar to the clinical differential considerations, other morphological causes of acute alveolar injury must be considered including hyperacute rejection, vascular anastomotic problems with intravascular thrombi, infection and severe acute cellular rejection. Immunohistochemical staining for viropathic organisms and acute antibody-mediated rejection is recommended. Appropriate histochemical and immunohistochemical staining, microbiological cultures and serologies (viral and donor specific antibody) are required. Currently only a few case reports have been published detailing the pathological changes. Death occurred in five patients despite aggressive interventions with plasmaphoresis and potent immunosuppressive agents. The current techniques, sensitivities and specificities for cross matches are detailed elsewhere. In the reported cases platelet-fibrin thrombi in the capillaries and small vessels were inconspicuous or absent. Deposits of immunoglobulin or complement in the vessels, alveolar septal structures and airspaces have been reported. Vascular and airway anastomotic complications the transplanted allograft is at risk of vascular and/or airway complications on account of a number of donor-related, surgical and immunosuppressive factors. Colonization of the donor airways by bacteria or fungi, mismatch of donor and recipient airway or vascular luminal measurements, the use of positive-pressure mechanical ventilation and the tension placed on the anastomosis, devascularization of the proximal airways with bronchial artery disruption and the delay in graft healing due to immunosuppression all play roles in the initiation and development of anastomotic problems. In particular, partial or complete venous obstruction remains a serious cause of early morbidity and mortality if not recognized and treated. Complete venous obstruction causes hemorrhagic infarction of the lung if surgical revision of the anastomosis is not performed promptly. Transesophageal echocardiography is an effective modality for assessing the anastomosis and for detecting obstruction. The bronchial arteries provide the primary blood supply to the distal trachea and initial 4:5 cm of the bronchi.
