The risk of death from any cause was 1.44 times higher in chronic kidney disease patients who also had pulmonary hypertension than in patients with kidney disease only, they found. Background:Pulmonary hypertension (PHT) is common in patients with end stage renal disease (ESRD). Of note, all cases of PAH were identified in the postdialysis study because in these cases pulmonary artery pressure remained abnormally high in the face of normalization of PWP after dialysis. Echo-Doppler studies can provide an estimate of the PASP, a surrogate of mean pulmonary artery pressure, which is calculated on the basis of the tricuspid regurgitation jet velocity [8]. • The other secondary causes of pulmonary hypertension should also be recognized and treated accordingly. The limitations of Doppler echocardiography for the diagnosis of PH are well known but there is no question that echo-Doppler is fundamental for the screening of PH and that this technique is a mainstay in the management of patients with PH. Nephrol Dial Transplant 2012; 27: 3908–3914. Prior to applying exclusion criteria, overall prevalence of PH at time of second evaluation was 56.8%. The prevalence of pulmonary hypertension in dialysis patients is relatively high and varies in different studies from 17% to 49.53% depending on the mode of dialysis and other selection factors, such as the presence of other cardiovascular comorbidities. At that time only one survey in dialysis patients was available [5] and this report showed an unexpectedly high prevalence of PH which was mainly attributed to high cardiac output secondary to the presence of arterio-venous fistula [6], anemia and/or fluid overload and to left ventricular (LV) disorders. The 10% prevalence of IPAH in PEPPER is a staggering figure when compared with the corresponding figure in the general population which is 15–50 cases per million population [3]. During two episodes of intradialytic systemic hypotension, the patient still had pulmonary hypertension by current definition. In the 2008 classification by the WHO and in more recent guidelines by the European Society of Cardiology (ESC) [4], for the first time attention was given to PH in dialysis patients which was classified in the fifth category, i.e. For Permissions, please e-mail: journals.permissions@oup.com. In the absence of pulmonary stenosis, right ventricular systolic pressure (RVSP) approximates PASP by echo-Doppler. (37.1%) patients had pulmonary hypertension (PHT), that is, a mean sPAP of more than 35 mmHg. Buemi M, Senatore M, Gallo GC, Crascì E, Campo S, Sturiale A, Coppolino G, Bolignano D, Frisina N. Kidney Blood Press Res.  |  27 peritoneal dialysis (PD) and 29 haemodialysis (HD) patients ( years, 37 males, dialysis vintage was months) had PAP measured by echocardiography. 23/42 subjects had worsening pulmonary pressure with upper arm access versus 4/16 for lower arm access (p=0.014). In the study by Agarwal [7], echocardiograms were performed 30–60 min after dialysis. Notwithstanding interest on PH in kidney failure is on the rise, information on the prevalence of PH in dialysis patients is scarce. Pulmonary arterial hypertension (PAH), defined as a rise in pulmonary arterial pressure (PAP) resulting from heart, lung or systemic disorders, is a common finding in patients on maintenance hemodialysis [3, 4] and an independent predictor of all-causes and cardiovascular mortality in maintenance hemodialysis patients [5,6,7,8]. the LV filling pressure) be ≤15 mmHg. It is also believed that microbubbles escaping from the dialysis circuit can trigger vasoconstriction and vascular sclerosis. All rights reserved.

Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. As expected, age, 24 h ABPM, increased inferior vena cava diameter in expiration, high left atrial dimension and high cardiac output were all related with PH. Additionally, pulmonary vessels show signs of endothelial dysfunction, dysregulation of vascular tone due to an imbalance in vasoactive substances, and local as well as systemic inflammation.

Overall in this study, which excluded patients with overt LV systolic dysfunction, PH (WHO II) likely attributable to LV diastolic dysfunction was as high as 65%. 2006 Sep-Oct;19(5):353-7. doi: 10.1111/j.1525-139X.2006.00186.x. (See related article by Agarwal. Treatment with an active vitamin D compound improves alterations in LV mass and function in experimental models [16] and in the PRIMO study, the use of the same compound [17] elicited a significant, clinically relevant reduction in the left atrial volume. As alluded to before, the WHO classification [3], endorsed by the ESC [4], contemplates five diagnostic categories for PH (Table 1). Patients often initially present to family physicians; however, because the symptoms are typically nonspecific or easily attributable to comorbid conditions, diagnosis can be challenging and requires a stepwise evaluation. Arterio-venous fistula, sleep apnea, accumulation of endogenous inhibitors of nitric oxide synthase, insult to pulmonary microcirculation attributable to exposure to dialysis membranes likely contribute to the unique propensity of dialysis patients to PH [11]. Prevalence, determinants and prognosis of pulmonary hypertension among hemodialysis patients. This study solidly confirms that PH is exceedingly common in this population (pulmonary artery systolic pressure, PASP, >45 mmHg in 16% of patients), and more importantly, it shows that the high risk (hazard rate ∼2) of death portended by this alteration is largely independent of volume expansion as estimated by the inferior vena cava diameter or by a combined biomarker of volume overload and LV diastolic dysfunction like left atrial volume. There is significant epidemiological overlap with kidney disease and the underlying causes of World Health Organization group 1–4 pulmonary hypertension (pulmonary • Duration of hemodialysis and arteriovenous access has been strongly related to the development of PH. Background: Pulmonary hypertension (PH) is common in patients with dialysis-dependent chronic kidney disease (CKD) and is an independent predictor of mortality. Moderate to severe PHT is a strong independent predictor of mortality in hemodialysis (HD) patients, and in those undergoing noncardiac surgery. Similarly, systolic LV dysfunction (by midwall fractional shortening) failed to account for the excess risk of PH because this alteration was associated with relatively higher, rather than lower, PASP. 2018 Jun 1;33(6):1010-1016. doi: 10.1093/ndt/gfx232. The frequency of PHT was higher in peritoneal dialysis patients but … Notwithstanding the fact that the diagnosis of PH demands right heart catheterization [3], until now only one study applying invasive hemodynamic measurements systematically has been performed in dialysis patients [12]. The pathogenesis of pulmonary hypertension is peculiar in ESRD, and understanding it is important to recognize such patients at the earliest and commence appropriate treatment. In these patients, just two relatively small studies based on Echo-Doppler estimates of PASP [13, 14] have been published so far. 2007;30(4):248-52. doi: 10.1159/000104443.

Apart from the study in this NDT issue [7], there is just one report dealing with the prevalence and outcomes of PH in these patients in the USA [15]. Is Pulmonary Hypertension a Rare Condition Associated to Angiostrongylosis in Naturally Infected Dogs? Location of dialysis access was significantly associated with progression of pulmonary hypertension.

The aim of this study was to relate pulmonary arterial pressure (PAP) to the cardiovascular status of dialysis patients. Patients with end-stage kidney disease (ESKD), particularly those on hemodialysis, are at risk for development of or worsening of preexisting pulmonary hypertension (PH).

The staggering cardiovascular risk of kidney failure and the disappointing results of very recent [18] and older trials [19] aimed at curbing the high risk of cardiovascular deaths in dialysis patients is a call to action that nephrologists should multiply efforts at identifying modifiable risk factors to improve the dim health perspectives of dialysis patients.

Pulmonary hypertension (PH) is common in patients with dialysis-dependent chronic kidney disease and is an independent predictor of mortality. Thank you for submitting a comment on this article. Several factors lead to the development and worsening of PH, and kidney dysfunction and volume overload are common occurrences in clinical practice that can lead to increased pulmonary artery (PA) pressure.

Pulmonary artery pressure correlated closely with fluid drainage during dialysis and inter-dialytic weight gain. We performed a systematic review and meta-analysis of the current available evidence examining the effect of existing PHT on relevant clinical outco… PASP in the 35–49 mmHg range and TRV between 2.8 m/s and 3.4 m/s are considered suggestive of PH [9] but not diagnostic of this condition. 111 An increased prevalence of OSA in patients with renal failure both predialysis and postdialysis is well documented.  |  As correctly recognized by Agarwal [7], the fact that the diagnosis of PH rested on indirect echocardiographic estimates is an obvious limitation of this study. Moving PH from the limbo category (WHO V) where it stands now to categories of known etiology may perhaps be a significant step forward towards this tantalizing goal. Pulmonary hypertension (PHT) is an independent predictor of mortality. the LV filling pressure) be ≤15 mmHg. Although multifactorial, the increased risk is due, in part, to the presence of an arteriovenous (AV) access. During the last 5 years, PH in patients with kidney diseases has attracted increasing attention and over 100 original or review articles dealing with PH in dialysis patients or in predialysis chronic kidney disease (CKD) and in transplant patients are now deposited in PubMed. Changes in pulmonary artery pressure (PAP) values before and after onset of hemodialysis via arteriovenous access, arteriovenous access compres- sion, and successful kidney transplantation were recorded. This study (PEPPER study: Prevalence of precapillary PAH in patients with end-stage renal disease) [12] considered 73 dialysis patients consecutively referred for unexplained dyspnea during ordinary physical activity or for more severe dyspnea to an academic department in Germany. Inaccuracy is a major limitation of echo-Doppler estimates, particularly so when the tricuspid regurgitation jet is difficult to visualize [10]. We recently have shown a high incidence of unexplained pulmonary hypertension (PHT) in end-stage renal disease (ESRD) patients on chronic haemodialysis (HD) therapy via … In patients with renal failure, the rostral overnight fluid shift with decumbency is associated with increased risk of OSA. High PAH in this condition is due to high vascular resistance at level of pulmonary arterioles while downstream pressure in the pulmonary veins and in the left heart chambers is normal (Figure 1). However, specific hemodynamics of the pulmonary circulation, changes induced by hemodialysis and characterization into pre- or postcapillary PH have not been evaluated in patients with chronic kidney disease. For the relationship between pulmonary hypertension and dialysis type, Fig 1 shows that the prevalence of pulmonary hypertension is lower in patients treated … Before commenting on some details of this interesting study, I will briefly recapitulate the diagnostic criteria for PH and the techniques for measuring pulmonary artery pressure in clinical practice. Pulmonary hypertension (PH) is highly prevalent in end-stage renal disease (ESRD) and associated with increased mortality. Effects of the arteriovenous fistula on pulmonary artery pressure and cardiac output in patients with chronic renal failure. A particular merit of this study was that right heart catheterization studies were repeated after dialysis in patients with PAP >25 mmHg. The patient reached prescribed dry weight but remained pulmonary hypertensive by definition. Also in the light of PEPPER study findings [12], this is an obvious strength of the present report. Abstract and Figures The information available in the literature regarding pulmonary hypertension (PH) in peritoneal dialysis (PD) patients is limited. In a previous study that examined the background diseases of patients with a Doppler echocardiographic diagnosis of pulmonary hypertension (PH), we reported elevated pulmonary artery pressure (PAP) in some patients with end-stage renal disease (ESRD) maintained on long-term hemodialysis via surgically created arteriovenous access. 112-114 Nocturnal hypoxia stimulates excess sympathetic nervous system activity, hyperaldosteronism, higher levels of blood pressure, resistant … This makes it harder for blood to flow through your lungs, and raises pressure within your lungs' arteries. The non-specific therapeutic options that proved to be beneficial in pulmonary artery pressure reduction are endothelin inhibitors, phosphodiesterase inhibitor sildenafil, and vasodilatory prostaglandins in various forms. 2009 Jul-Sep;10(3):160-6. doi: 10.1177/112972980901000305. As mentioned, the independent risk of death in patients with PH was doubled when compared with those without PH and the inclusion of inferior vena cava diameter and left atrial dimension only slightly reduced the HR of death associated with PH implying that residual volume expansion after dialysis is unlikely to explain the risk excess of PH. … The studies which have evaluated the association of PHT with renal transplant outcomes have shown conflicting results. A formal diagnosis of pulmonary artery hypertension (PAH, WHO category I) requires invasive hemodynamic studies and demands that the mean pulmonary artery pressure be ≥25 mmHg associated with pulmonary vascular resistance >3 Woods Units and that pulmonary wedge pressure (PWP, i.e. In patients with end stage renal disease (ESRD), pulmonary hypertension is a frequently described complication with different etiology. In this diagnostic category, PWP is high (>15 mmHg) because the increase in LV pressure attributable to LV disorders is transmitted back to atrium and pulmonary veins and to the pulmonary artery. The use of vitamin D together with the left atrial dimension and urea reduction ratio emerged as the sole independent correlates of PH [7]. Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. Fudim M, Stanton A, Sobotka PA, Dolan E, Krum H. Curr Hypertens Rep. 2014 Dec;16(12):497. doi: 10.1007/s11906-014-0497-x. Among these patients, three met hemodynamic criteria for idiopathic PAH (IPAH, WHO I) and one additional patient turned out to have PAH attributable to sleep apnea. Carmine Zoccali, Pulmonary hypertension in dialysis patients: a prevalent, risky but still uncharacterized disorder, Nephrology Dialysis Transplantation, Volume 27, Issue 10, October 2012, Pages 3674–3677, https://doi.org/10.1093/ndt/gfs425. 2006;15:353-360. Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. The prevalence of pulmonary hypertension in dialysis patients is relatively high and varies in different studies from 17% to 49.53% depending on the mode of dialysis and other selection factors, such as the presence of other cardiovascular comorbidities. Published by Oxford University Press on behalf of ERA-EDTA. Disparate thresholds of PASP by Echo-Doppler estimates have been adopted for the diagnosis of PH in the various studies performed so far and a recent systematic review clearly shows that the prevalence reported in these studies is critically dependent on the threshold chosen for diagnosis [11]. Epub 2005 Apr 19. 2006 Jul;15(4):353-60. doi: 10.1097/01.mnh.0000232874.27846.37. Pulmonary hypertension is common in hemodialysis (HD) patients and it is associated with an increased death risk, a study found.. Vitamin D improves pulmonary function in a rat model for congenital diaphragmatic hernia. These patients were initially screened by echo-Doppler and those with LV systolic dysfunction (ejection fraction <50%), valvular heart disease and other heart diseases were excluded along with those with uncontrolled hypertension, malignant diseases, anemia (Hb <10 g) or preexisting lung disease. Thinking outside the box: a middle-aged man with new-onset dyspnoea on exertion and pedal oedema. Nephrol Dial Transplant. In 1973 at a conference endorsed by the World Health Organization (WHO), a classification based on two categories only (primary and secondary PH) was proposed [1]. This site needs JavaScript to work properly. The third category (WHO III) includes PH secondary to lung diseases and sleep apnea, the fourth (WHO IV) pulmonary artery occlusive diseases due to thromboembolic phenomena and other occlusive/compressive phenomena and the fifth (WHO V), the one considering PH in dialysis patients, a miscellaneous group of forms on uncertain etiology.
