Utility of Endoscopy in Hospitalized Patients with Gastrointestinal Hemorrhage and Pulmonary Hypertension. Dig Dis Sci 2021; 66:4159-4168. [PMID: 33428039 PMCID: PMC9206875 DOI: 10.1007/s10620-020-06803-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 12/17/2020] [Indexed: 12/09/2022]
Abstract
BACKGROUND Gastrointestinal hemorrhage (GIH) has been reported as one of the most common GI complications in patients with pulmonary hypertension (PH). There is paucity of data on the national burden of GIH in patients with PH. We aimed to assess the prevalence, trends and outcomes of endoscopic interventions in patients with PH who were admitted with GIH. METHOD We queried National Inpatient Sample (NIS) database from 2005 to 2014 and identified the patients hospitalized with primary or secondary discharge diagnosis of PH (ICD 9 CM Code: 416.0, 416.8, and 416.9). Using Clinical Classification Software Coding system (153) patients with concurrent diagnosis of GIH were then identified. We studied the prevalence and trends of GIH in PH, factors associated with GIH, use of endoscopy, factors associated with utilization of endoscopic interventions, endoscopy outcomes including mortality, and overall healthcare burden. RESULTS Out of 7,586,973 PH hospitalizations 3.2% (N = 246,358) had concurrent GIH, with a rising prevalence of GIH in PH patients during the last decade. Clinical predictors for GIH in PH included older age, congestive heart failure, anticoagulation therapy and concurrent alcohol abuse. Mean length of stay (LOS) in PH patients hospitalized with GIH was significantly higher than without GIH (8.6 vs. 6.4 days, p < 0.01) along with a significant increase in hospitalization cost ($20,189 vs. $14,807, p < 0.01). Similarly, odds of in-hospital mortality increase by ~ 1.5 times in PH patients with GIH than those without it (adjusted odds ratio [aOR: 1.45, 95%CI: 1.43-1.47]). Endoscopic interventions were performed in 48.6% of patients with PH and GIH during their hospitalization. Older patients were more likely to undergo endoscopy, as well as the patients who received blood transfusion, and those with hypovolemic shock. Patients with acute respiratory failure and acute renal failure were less likely to get endoscopy. Mean LOS in patients undergoing endoscopic intervention was significantly higher than those who did not receive any intervention (8.7 vs. 8.4 days, p < 0.01), without a substantial increase in hospitalization cost ($20,344 vs. $20,041, p < 0.01). Also, there was a significant decrease in in-hospital mortality in patients undergoing endoscopic interventions. CONCLUSION Concurrent GIH in patients with PH increases length of stay; healthcare costs and increases in-hospital mortality. Use of endoscopic interventions in these patients is associated with reduced length of stay, in-hospital mortality without significantly increasing the overall health care burden and should be considered in hospitalized patients with PH who are admitted with GIH. Future studies comparing GIH patients with and without PH should be done to assess if PH is a risk factor for worse outcomes. CLINICAL TRIAL REGISTRATION NUMBER No IRB required due to use of national de-identified data.

Abstract
Budd-Chiari syndrome and non-cirrhotic non-tumoral portal vein thrombosis are 2 rare disorders, with several similarities that are categorized under the term splanchnic vein thrombosis. Both disorders are frequently associated with an underlying prothrombotic disorder. They can cause severe portal hypertension and usually affect young patients, negatively influencing life expectancy when the diagnosis and treatment are not performed at an early stage. Yet, they have specific features that require individual consideration. The current review will focus on the available knowledge on pathophysiology, diagnosis and management of both entities.

Abstract
Portopulmonary hypertension (PoPH) refers to the condition that pulmonary arterial hypertension (PAH) occur in the stetting of portal hypertension. The development of PoPH is thought to be independent of the severity of portal hypertension or the etiology or severity of liver disease. PoPH results from excessive vasoconstriction, vascular remodeling, and proliferative and thrombotic events within the pulmonary circulation that lead to progressive right ventricular failure and ultimately to death. Untreated PoPH is associated with a poor prognosis. As PoPH is frequently asymptomatic or symptoms are generally non-specific, patients should be actively screened for the presence of PoPH. Two-dimensional transthoracic echocardiography is a useful non-invasive screening tool, but a definitive diagnosis requires invasive hemodynamic confirmation by right heart catheterization. Despite a dearth of randomized, prospective data, an ever-expanding clinical experience shows that patients with PoPH benefit from therapy with PAH-specific medications including with endothelin receptor antagonists, phosphodiesterase-5 inhibitors, and/or prostanoids. Due to high perioperative mortality, transplantation should be avoided in those patients who have severe PoPH that is refractory to medical therapy.

Abstract
Porto-pulmonary hypertension (PoPH) is a rare but threatening vasculopathy, defined by the presence of pulmonary arterial hypertension (PAH) in the setting of portal hypertension. Although most commonly observed in cirrhotic patients, those with non-cirrhotic portal hypertension are also at risk of developing it. Little is known about the mechanisms by which PAH develop in patients with portal hypertension, but genetic factors, pulmonary vascular wall shear stress, and a dysregulation of vasoactive, proliferative and inflammatory mediators might be involved. PoPH is estimated to occur in 3 to 10% of patients with end-stage liver disease, although its frequency is not related to the severity of liver dysfunction or the degree of portal hypertension. Moderate-to-severe PoPH portends an extremely poor prognosis. Presentation is highly variable, therefore a high index of suspicion is required to establish the diagnosis. PoPH should be screened by transthoracic echocardiography (TTE) in cirrhotic patients presenting with dyspnoea as well as in all patients being evaluated for liver transplantation (LT) regardless of their symptoms. If TTE shows elevated pulmonary pressures, patients should undergo right heart catheterisation, which is required for the definitive diagnosis of PoPH. Without LT, the overall 5-year mortality in PoPH patients is 70%, but it should not be considered an indication for LT. Moderate-to-severe PoPH contraindicates LT, since it is associated with a prohibitively increased intra and postoperative mortality. However, there is now evidence supporting the use of PAH-specific therapies pre-LT in order to improve pulmonary haemodynamic measurements, so the procedure can then be performed with significantly lower risks.

Abstract
Current classifications of pulmonary hypertension have contributed a great deal to our understanding of pulmonary vascular disease, facilitated drug trials, and improved our understanding of congenital heart disease in adult survivors. However, these classifications are not applicable readily to pediatric disease. The classification system that we propose is based firmly in clinical practice. The specific aims of this new system are to improve diagnostic strategies, to promote appropriate clinical investigation, to improve our understanding of disease pathogenesis, physiology and epidemiology, and to guide the development of human disease models in laboratory and animal studies. It should be also an educational resource. We emphasize the concepts of perinatal maladaptation, maldevelopment and pulmonary hypoplasia as causative factors in pediatric pulmonary hypertension. We highlight the importance of genetic, chromosomal and multiple congenital malformation syndromes in the presentation of pediatric pulmonary hypertension. We divide pediatric pulmonary hypertensive vascular disease into 10 broad categories.

Abstract
The plexiform lesions of severe pulmonary hypertension (PH) are complex vascular structures composed primarily of endothelial cells. In this study, we use immunohistochemical markers to identify the various cell layers of pulmonary vessels and to identify different endothelial cell phenotypes in pulmonary arteries affected by severe PH. Our computerized three-dimensional reconstructions of nine vessels in five patients with severe PH demonstrate that plexiform (n = 14) and concentric-obliterative (n = 6) lesions occur distal to branch points of small pulmonary arteries. And, whereas plexiform lesions occur as solitary lesions, concentric-obliterative lesions appear to be only associated with, and proximal to, plexiform structures. The endothelial cells of plexiform lesions express intensely and uniformly the vascular endothelial growth factor (VEGF) receptor KDR and segregate phenotypically into cyclin-kinase inhibitor p27/kip1-negative cells in the central core of the plexiform lesion and p27/kip1-positive cells in peripheral areas adjacent to incipient blood vessel formation. Using immunohistochemistry and three-dimensional reconstruction techniques, we show that plexiform lesions are dynamic vascular structures characterized by at least two endothelial cell phenotypes. Plexiform arteriopathy is not merely an end stage or postthrombotic change--it may represent one stage in an ongoing, angiogenic endothelial cell growth process.

Abstract
Patients with primary pulmonary hypertension develop vascular lesions characterized by proliferated blood channels, the so-called plexiform lesions. These lesions are often associated with concentric intimal obliteration of pulmonary vessels. We report that the lungs of three patients with scleroderma-associated pulmonary hypertension showed a predominance of obliterative-concentric lesions, with relatively few plexiform or combined lesions. In contrast, plexiform lesions predominated in the lungs obtained from three patients with human immunodeficiency virus (HIV)-associated pulmonary hypertension; pure obliterative-concentric lesions were infrequent. Both plexiform and concentric obliterative lesions stained strongly positive for the endothelial cell marker factor VIII-related antigen. Muscle-specific actin immunostaining highlighted the smooth muscle cells of the tunica media of plexiform vessels, but not the luminal layers of the concentric-obliterative lesions. Proliferating cells, as determined by immunostaining with the MIB-1 antibody, were only detected in the plexiform vascular lesions. We postulate that concentric-obliterative lesions and plexiform lesions are temporally and etiologically related. A scaffolding of proliferating endothelial cells could be the common denominator of both lesions. Our hypothesis that there exists a chronological continuum, proceeding from early, proliferative plexiform lesions to late, nonproliferative concentric-obliterative lesions in primary and secondary pulmonary hypertension, may lead to better targeted treatment strategies and disease classification.

Abstract
The hepatopulmonary syndrome results from erythrocytes bypassing the lung without oxygenation. In addition to ventilation-perfusion mismatching, the hypoxemia may result from portapulmonary shunting, passage around alveoli through pleural and hilar blood vessels, and intrapulmonary vascular dilatations. Dilated vascular channels between arteries and veins on the pleural surface are seen more often than dilated intrapulmonary capillaries in chronic liver disease. These anastomoses appear grossly as vascular "spider nevi" on the pleura. Portal vein-to-pulmonary vein anastomoses could produce arterial hypoxemia because the deoxygenated portal venous blood can mix with oxygenated pulmonary venous blood. There is an association of esophageal varices with the hepatopulmonary syndrome and anastomoses between the portal veins and pulmonary veins have been found in both animals and humans. As portal pressures increase, the mediastinal veins enlarge, enhancing the chance that they may penetrate the pleura and drain into pulmonary veins. Direct splenic injections in patients, however, suggest that this shunt pathway is uncommon and small. Pulmonary artery injection studies have demonstrated dilated intrapulmonary vascular segments in humans and animals. Dilation of capillaries may allow a more rapid flow through the lung and the greater distance between the erythrocyte and alveolar wall may make it more difficult to oxygenate rapidly passing erythrocytes. Pulmonary capillary dilation can explain the abnormalities of the perfusion lung scan and contrast echocardiogram that portapulmonary shunting cannot. Pulmonary hypertension may occur in chronic liver disease even without arterial hypoxemia, but it is rare. The prevalence of hypertensive pulmonary vascular disease in patients with cirrhosis of the liver is less than 1%, although a higher percentage (2%) has been found when patients with portal hypertension were studied by cardiac catheterization. The hypertensive pulmonary vascular disease (pulmonary arteriopathy with plexiform lesions) that occurs in patients with liver disease appears identical to that encountered in patients with congenital cardiac shunts and unexplained (primary) pulmonary hypertension.

Abstract
Pulmonary hypertension is well described in association with portal hypertension of any cause including end stage primary biliary cirrhosis (PBC). The essential feature of this association is the presence of portosystemic shunting, including surgically created shunts. A patient with primary pulmonary hypertension and PBC without portal hypertension is reported. This suggests that primary pulmonary hypertension may be associated with PBC in the absence of portal hypertension. Decisions regarding appropriate organ transplantation may depend on whether pulmonary hypertension is primary or secondary to portal hypertension.

Abstract
A case of multiple focal nodular hyperplasia (FNH) of the liver associated with noncirrhotic portal hypertension and later complicated by pulmonary arterial hypertension leading to death from right heart failure is reported. In retrospect, the portal hypertension diagnosed in early life was most likely due to a congenital hypoplasia of portal vein branches and multiple FNH, a hyperplastic response of the liver parenchyma in association with anomalies of hepatic arterial branches as found within the lesions. This case may represent a form of multiple FNH syndrome restricted to the liver, because neither extrahepatic vascular malformation nor brain tumor was identified at autopsy. The FNH lesions had considerably expanded over the years, and the severe sinusoidal congestion due to chronic right-sided heart failure with subsequent prolonged parenchymal exposure to blood-borne hepatotrophic factors is a likely explanation for both the massive enlargement of FNH lesions and the nodular regenerative hyperplasia observed in the intervening parenchyma.

Abstract
A 10-year-old boy who had portal hypertension secondary to portal fibrosis/intrahepatic biliary atresia developed syncopal episodes related to strenuous activity. A work-up excluded a metabolic or neurologic etiology and cardiac catheterization demonstrated significant pulmonary hypertension. Six months later he died and an autopsy revealed pulmonary plexogenic arteriopathy without microemboli. Previous reported cases of this symptom complex are reviewed. In addition, he had a history of nonspecific colitis, ulcerative stomatitis, and conjunctivitis responsive to steroid therapy. The possible relationship of these manifestations to the portal pulmonary pathology is discussed.

Abstract
To determine the clinical, laboratory and hemodynamic profile in patients with primary pulmonary hypertension and associated portal hypertension, 7 new cases and 71 previously reported cases were analyzed. There was no gender predilection and the average age at diagnosis was 41 years. Liver cirrhosis was the most frequent cause of hypertension (82%) and a surgical portosystemic shunt was present in 29%. Almost invariably, portal hypertension either preceded or was diagnosed concurrently with pulmonary hypertension, favoring the hypothesis that in portal hypertension, the pulmonary vasculature may be exposed to vasoactive substances normally metabolized or produced by the diseased liver, possibly inducing vasoconstriction or direct toxic damage to the pulmonary arteries. Clinically, exertional dyspnea was the most frequent presenting symptom (81%); other symptoms, such as syncope, chest pain and fatigue, were present in less than 33%. An accentuated pulmonary component of the second heart sound (82%) and a systolic murmur (69%) were the most common physical findings. At least 75% of these patients had evidence of pulmonary hypertension on electrocardiography (right ventricular hypertrophy) or roentgenography (cardiomegaly or dilated main pulmonary arteries, or both). Hemodynamic findings included severe pulmonary hypertension (mean pulmonary artery pressure 59 +/- 19 mm Hg) with normal pulmonary capillary wedge pressure and cardiac output. Treatment was basically palliative and the mean and median survival times were 15 and 6 months, respectively. In brief, on the basis of clinical presentation and laboratory features, patients with combined primary pulmonary hypertension and portal hypertension seldom represent a diagnostic challenge. Further research is needed on treatment, which remains palliative. The survival rate is poor and worse than that seen in isolated primary pulmonary hypertension.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The prevalence of pulmonary hypertension in 507 patients hospitalized with portal hypertension but without known pulmonary hypertension who underwent cardiac catheterization was prospectively studied. Ten (2%) of these patients, 6 of whom were clinically asymptomatic, had primary pulmonary hypertension. Second, 26 patients with symptomatic pulmonary hypertension complicating portal hypertension were reviewed. Pulmonary hypertension occurred later after diagnosis of portal hypertension in patients with a surgical shunt (10 patients) than in those without a shunt (147 +/- 49 vs. 44 +/- 27 months; P less than 0.0001). Cardiac index correlated inversely with pulmonary arterial pressure (r = -0.45; P less than 0.01) and was lower in the 5 patients who died of pulmonary hypertension than in the 5 who died of liver failure (1.52 +/- 0.14 vs. 3.69 +/- 1.88 L/min.m2; P less than 0.05). Third, systemic and splanchnic hemodynamics were compared in 285 patients with alcoholic cirrhosis and 29 controls. No significant relation was found between elevated pulmonary vascular resistance and increased portal pressure, zzygos blood flow, or cardiac index. Pulmonary hypertension is considerably more frequent than was previously estimated in patients with portal hypertension. The risk of developing pulmonary hypertension could increase with the duration of portal hypertension without any clear relation to the degree of portal hypertension, hepatic failure, or amount of blood shunted.

Abstract
A study was made of the number of pulmonary endocrine cells, immunoreactive for gastrin-releasing peptide (bombesin) or calcitonin, in the terminal bronchioles of 39 cases of pulmonary vascular disease. In 25 of these, the form of vascular disease was plexogenic pulmonary arteriopathy, primary in 12 and secondary in 13, while the remaining 14 subjects had a wide range of other varieties of hypertensive pulmonary vascular disease. We found that pulmonary endocrine cells, especially those containing bombesin, were increased in number in both the primary and secondary forms of plexogenic pulmonary arteriopathy but not in other varieties of pulmonary hypertension. The prominent bombesin-containing cells were found in cases with cellular plexiform lesions but occurred even more prominently at an earlier stage when vascular smooth muscle cells were migrating from the inner media into the intima.

Abstract
Patients with portal hypertension of varying etiology may develop pulmonary artery hypertension. In the present autopsy study, pulmonary and hepatic tissue was studied in 12 patients in whom pulmonary and portal hypertension coexisted. Plexogenic pulmonary arteriopathy was present in 10 patients, 7 of whom had coexistent thromboembolic lesions. One patient had isolated medial hypertrophy, which may be an early stage in the plexogenic category, whereas isolated thromboembolic pulmonary vascular disease was observed in one subject. Hepatic disease was consistent with alcoholic cirrhosis in seven patients, cryptogenic cirrhosis in four and extrahepatic portal hypertension without cirrhosis in one. Thrombocytopenia was present in all 10 patients whose platelet count was determined. This study suggests that pulmonary hypertension associated with portal hypertension commonly has a plexogenic appearance on histologic examination. However, thrombosis (whether embolic or in situ) may also contribute to vascular obstruction.

Abstract
During the course of a case of primary pulmonary hypertension occurring in a 24 year old man lung tissue became available at heart-lung transplantation in 1986 and from a lung biopsy carried out in 1981. In 1986 the sections showed classic plexogenic pulmonary arteriopathy. In 1981 they revealed migration of myofibroblasts into the intima and lumen of pulmonary arteries and arterioles, the identification of the cells being confirmed by electron microscopy. During the five years that the pulmonary vascular pathology progressed to the formation of plexiform lesions there was an increase in the number of bronchiolar endocrine cells that were immunoreactive to bombesin and calcitonin. This study demonstrates that the classic pathogenesis of primary plexogenic pulmonary arteriopathy originates years earlier as a migration of cells of muscular pedigree from the media into the intima of the pulmonary arteries and arterioles.

Abstract
Histological changes of the pulmonary vasculature in comparison with that of the portal vein in necropsy cases of severe hepatic injury that had not been associated with clinical pulmonary hypertension were analysed qualitatively and quantitatively. The main changes of the intra-hepatic portal vein were dilatation (88.3 per cent), thickening of the wall (58.5 per cent) and thrombi (22.3 per cent). The changes of the pulmonary vasculature were limited to muscular type arteries, which showed dilatation (31.9 per cent), thickening of the wall (30.9 per cent) and thrombi (10.6 per cent). Association of wall thickening of the portal vein and the small pulmonary artery was observed in 30.9 per cent, these associations being statistically significant. Coincidence of thrombus formation in the portal vein and pulmonary vasculature was observed only in 4.3 per cent, which was not statistically significant. After the circumferences of the internal and external elastic laminae of small pulmonary arteries and the cross-sectional area of the media were measured, the anatomical radius and wall thickness of each artery were calculated according to Furuyama 's method. The relations between the anatomical radii and wall thickness of small pulmonary arteries in controls and hepatic cirrhosis groups were investigated by analysis of covariance to compare the equality of the two corresponding regression lines. The wall thickness and the ratio of wall thickness to the anatomical radius of small pulmonary arteries were significantly larger in the cirrhotic group than in the control group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A patient with both extrahepatic portal hypertension and primary pulmonary hypertension is reported. The pulmonary hypertension developed without a surgical portal-systemic shunt, and at autopsy there was no evidence of a large spontaneous shunt. This association of pulmonary arterial hypertension and portal venous hypertension without either intrinsic liver disease or a large portal-systemic anastomosis has not been reported previously. Our case supports the concept that portal hypertension with its attendant portal-systemic collateral circulation may be the major predisposing cause of pulmonary hypertension both in intrinsic liver disease and extrahepatic portal vein obstruction.

Abstract
Pulmonary arterial hypertension with severe pulmonary vascular disease is a rare association of portal hypertension in man, be it the result of cirrhosis of the liver or obstruction of the portal vein. We induced portal hypertension in 23 rats by partially ligating the portal vein or by totally occluding it in two stages. The rats were killed between one and 15 months after operation. A collateral circulation of varicose, anastomotic vessels was established, and in six animals well-marked oesophageal varices developed. Despite this evidence of sustained portal hypertension, hypertrophy did not develop in the right ventricle or in the media of the pulmonary trunk or muscular pulmonary arteries in any of the animals. This suggests that mechanical obstruction of the portal vein per se is not responsible for the development of pulmonary hypertension. Other factors, perhaps of a humoral nature, appear to be required to induce this rare association of portal hypertension but we have been unable to identify these. In particular, blood levels of oestrogen were not raised after ligation of the portal vein.

Abstract
Pulmonary arteries from a case of plexogenic pulmonary arteriopathy were studied with the electron microscope. Many muscular pulmonary arteries showed intimal fibrosis of concentric or "onion-skin" type. The cells embedded within this fibrosis resembled smooth muscle but since they also possessed some features of fibroblasts we refer to them as myofibroblasts. Myofibroblasts also occurred in plexiform lesions together with fibroblasts and "fibrillary cells". These fibrillary cells contained numerous, prominent filaments with a random orientation. They lined the vascular channels of the plexiform lesions as well as being present within the stroma. They appeared to phagocytose fibrin and then to organise the plexiform lesion into a fibrous scar. Fibrillary cells closely resemble vasoformative reserve cells and the cells of the cardiac myxoma and so-called "papillary tumour" of heart valves. They may, therefore, be primitive multipotential cells found throughout the entire cardiovascular system.
