Background:Pulmonary hypertension (PHT) is common in patients with end stage renal disease (ESRD). As alluded to before, the WHO classification [3], endorsed by the ESC [4], contemplates five diagnostic categories for PH (Table 1). 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. 27 peritoneal dialysis (PD) and 29 haemodialysis (HD) patients ( years, 37 males, dialysis vintage was months) had PAP measured by echocardiography. Pulmonary artery pressure correlated closely with fluid drainage during dialysis and inter-dialytic weight gain. Pulmonary hypertension (PHT) is an independent predictor of mortality. Karur GR, Wald R, Goldstein MB, Wald R, Jimenez-Juan L, Kiaii M, Leipsic J, Kirpalani A, Bello O, Barthur A, Ng MY, Deva DP, Yan AT. Fifty-eight patients met the inclusion criteria and 31 of these consented to undergo right heart catheterization. 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. doi: 10.1136/bcr-2015-209724. 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. Pulmonary hypertension and erythropoietin. In other words, the pressure in the pulmonary artery is only passively increased as a consequence of an underlying LV disorder (Figure 1). ), Oxford University Press is a department of the University of Oxford. 23/42 subjects had worsening pulmonary pressure with upper arm access versus 4/16 for lower arm access (p=0.014). [2] Agarwal R. Prevalence, determinants and prognosis of pulmonary hypertension among hemodialysis patients. 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. Thinking outside the box: a middle-aged man with new-onset dyspnoea on exertion and pedal oedema.

Even though this study was small, it unquestionably shows that PAH is exceedingly frequent in dialysis patients. Buemi M, Senatore M, Gallo GC, Crascì E, Campo S, Sturiale A, Coppolino G, Bolignano D, Frisina N. Kidney Blood Press Res. In these patients, just two relatively small studies based on Echo-Doppler estimates of PASP [13, 14] have been published so far. Pulmonary hypertension (PH) is highly prevalent in end-stage renal disease (ESRD) and associated with increased mortality. The PEPPER study [12] is the sole to provide information on PH in predialysis stage 3–4 CKD patients. Pulmonary hypertension associated with end-stage renal disease (ESRD) is an important yet under-recognized condition and can lead to life-threatening complications. 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.

In the absence of pulmonary stenosis, right ventricular systolic pressure (RVSP) approximates PASP by echo-Doppler. 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.

Your comment will be reviewed and published at the journal's discretion. 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 thrill of success: central arterial-venous anastomosis for hypertension. 2006;15:353-360. Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and 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. 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. 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]. 2018 Jun 1;33(6):1010-1016. doi: 10.1093/ndt/gfx232. … Pulmonary hypertension in end-stage renal disease patients is associated with significantly increased morbidity and mortality. 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. [1] Abassi z, Nakhoul f, Khankin e, et al. 2009 Jul-Sep;10(3):160-6. doi: 10.1177/112972980901000305. 2006 Jul;15(4):353-60. doi: 10.1097/01.mnh.0000232874.27846.37. Inaccuracy is a major limitation of echo-Doppler estimates, particularly so when the tricuspid regurgitation jet is difficult to visualize [10]. We investigated the risk factors for pulmonary hypertension (PH) in patients receiving maintenance peritoneal dialysis (MPD). Prevalence, determinants and prognosis of pulmonary hypertension among hemodialysis patients. 111 An increased prevalence of OSA in patients with renal failure both predialysis and postdialysis is well documented. Pulmonary hypertension (PH) is a complex hemodynamic alteration which may result from disparate causes. Results:PH > 35 mm Hg was found in 39.7% of patients receiving hemodialysis (mean SD, Indian J Nephrol. It is also believed that microbubbles escaping from the dialysis circuit can trigger vasoconstriction and vascular sclerosis. A. Unal, M. Sipahioglu, F. Oguz, et al.Pulmonary hypertension in peritoneal dialysis patients: prevalence and risk factors Perit Dial Int, 29 (2009), pp. Pulmonary hypertension is common in hemodialysis (HD) patients and it is associated with an increased death risk, a study found.. • The other secondary causes of pulmonary hypertension should also be recognized and treated accordingly. 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. We evaluated the impact of fluid retention measured by bioimpedance on the prevalence of PH in this patient cohort. 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]. 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. The patient reached prescribed dry weight but remained pulmonary hypertensive by definition. For Permissions, please e-mail: journals.permissions@oup.com. Is Pulmonary Hypertension a Rare Condition Associated to Angiostrongylosis in Naturally Infected Dogs? Curr Opin Nephrol Hypertens. 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. A group of 180 end-stage renal disease patients (124 men and 56 women; mean age: 56.43±8.36) were enrolled in our study, which … 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. 2006 Sep-Oct;19(5):353-7. doi: 10.1111/j.1525-139X.2006.00186.x. 2018 Mar-Apr;28(2):127-134. doi: 10.4103/ijn.IJN_36_17. eCollection 2016 Aug. Rochlani YM, Pai VB, Lataifeh AR, Bartter T. BMJ Case Rep. 2015 May 7;2015:bcr2015209724. PH among ESKD patents is presented in this topic review. Patients and methods: Among 66 patients with ESRD, 48 patients participated in the study. Typical pressure profiles in right heart catheterization studies of a patient with (compensated) PAH and of a patient with PH secondary to LV disorders. Intriguingly, the lack of use of vitamin D receptor activator emerged as a relevant correlate of PH and this link was maintained also on multiple regression analysis. Yigla M, Abassi Z, Reisner SA, Nakhoul F. Semin Dial. This site needs JavaScript to work properly. 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]. PH also complicates chronic hemodialysis (HD) therapy immediately after the creation of an arteriovenous (AV) access, even before starting HD therapy. 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. Fudim M, Stanton A, Sobotka PA, Dolan E, Krum H.

Notwithstanding interest on PH in kidney failure is on the rise, information on the prevalence of PH in dialysis patients is scarce. Pulmonary hypertension (PH) is a progressive, fatal pulmonary circulatory disease that accompanies left or right ventricular failure. 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.
