In the summer of 2016, delegates from the German Respiratory Society, the German Society of Cardiology and the German Society of Pediatric Cardiology met in Cologne, Germany, to define consensus-based practice recommendations for the management of patients with pulmonary arterial hypertension (PAH). These recommendations were built on the 2015 European Pulmonary Hypertension guidelines and included new evidence, where available. The treatment algorithm for PAH was modified based on the observation that there are now many patients diagnosed with IPAH who are at an advanced age and have significant cardiopulmonary comorbidities. For patients newly diagnosed with classic forms of PAH, i.e. younger patients without significant cardiopulmonary comorbidities, the consensus-based recommendation was to use initial combination therapy as the standard approach. The use of monotherapies was no longer considered appropriate in such patients. The choice of treatment strategies should be based on the risk assessment as proposed in the European guidelines. In patients presenting with a low or intermediate risk, oral combination therapy with endothelin receptor antagonists and phosphodiesterase-5 inhibitors or soluble guanylate cyclase stimulators, respectively, should be used. In high-risk patients, triple combination therapy including a subcutaneous or intravenous prostacyclin analogue should be considered. For patients who suffer from PAH and significant cardiopulmonary comorbidities, initial monotherapy is recommended and the use of combination therapies should be considered on an individual basis. The latter recommendations are based on the scarcity of evidence supporting the use of combination therapy and the higher risk of drug-related adverse events in such patients., (Copyright © 2018 Elsevier B.V.

The 2009 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension (PH) have been adopted for Germany. While the guidelines contain detailed recommendations regarding pulmonary arterial hypertension (PAH), they contain only a relatively short paragraph on other, much more frequent forms of PH including PH owing to left heart disease. The guidelines point out that the drugs currently used to treat patients with PAH (prostanoids, endothelin receptor antagonists and phosphodiesterase type 5 inhibitors) have not been sufficiently investigated in other forms of PH. However, despite the lack of respective efficacy data an uncritical use of targeted PAH drugs in patients with PH associated with left heart disease is currently observed at an increasing rate. This development is a matter of concern. On the other hand, PH is a frequent problem that is highly relevant for morbidity and mortality in patients with left heart disease. It that sense, the practical implementation of the European Guidelines in Germany requires the consideration of several specific issues and already existing novel data. This requires a detailed commentary to the guidelines, and in some aspects an update already appears necessary. In June 2010, a Consensus Conference organized by the PH working groups of the German Society of Cardiology (DGK), the German Society of Respiratory Medicine (DGP) and the German Society of Pediatric Cardiology (DGPK) was held in Cologne, Germany. This conference aimed to solve practical and controversial issues surrounding the implementation of the European Guidelines in Germany. To this end, a number of working groups was initiated, one of which was specifically dedicated to PH due to left heart disease. This commentary describes in detail the results and recommendations of the working group which were last updated in October 2011., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

The 2009 European Guidelines on Pulmonary Hypertension did not cover only pulmonary arterial hypertension (PAH) but also some aspects of pulmonary hypertension (PH) in chronic lung disease. These guidelines point out that the drugs currently used to treat patients with PAH (prostanoids, endothelin receptor antagonists and phosphodiesterase type-5 inhibitors) have not been sufficiently investigated in other forms of PH. Therefore, the use of these drugs in patients with chronic lung disease and PH is not recommended. This recommendation, however, is not always in agreement with medical needs as physicians feel sometimes inclined to also treat other forms of pulmonary hypertension which may affect the quality of life and survival of these patients in a similar manner as in PAH. In June 2010, a consensus conference was held in Cologne, Germany, to discuss open and controversial issues surrounding the practical implementation of the European Guidelines. The conference was sponsored by the German Society of Cardiology, the German Society of Respiratory Medicine and the German Society of Pediatric Cardiology (DGK, DGP and DGPK). To this end, a number of working groups were initiated, one of which was specifically dedicated to the diagnosis and treatment of PH due to chronic lung disease.

This study aimed to describe health care provision, resource consumption and related costs, as well as treatment patterns and quality of life in adult patients with pulmonary arterial hypertension (PAH) in Germany. Data for this retrospective and prospective cost-of-illness-study were derived from hospitals, general practitioners and patients. Costs were evaluated from the perspective of third party payer and patient. Quality of life data were collected by using three validated instruments. A total of 167 patients were enrolled at 10 hospitals. Time period from first occurrence of symptoms to confirmed diagnosis of PAH was 2.3 years on average. Mean number of GP visits was 1.5 per patient per month, and within 15 months, inpatient stays were reported for 50% of patients. The ratio of combination therapy to single-drug therapy for endothelin receptor antagonists, phosphodiesterase-5-inhibitor and prostacyclin analogues increased significantly during 15 months. Treatment costs were, on average, euro47,400 per patient per year, arising mainly from drugs. Compared to the general population, quality of life of PAH patients was considerably impaired. This is the first study which evaluated aspects of the medical and economic consequences of PAH based on a large cohort of PAH patients in Germany., (Copyright 2010 Elsevier Ltd.

Aims: To describe the clinical and haemodynamic effects during the first 6 months of continuous intravenous iloprost treatment in patients with idiopathic pulmonary arterial hypertension (IPAH) and relevant disease progression despite continued mono therapy with aerosolized iloprost., Methods and Results: Twenty-four IPAH patients with clinical decompensation to NYHA class IV despite therapy with aerosolized iloprost and optimized conservative treatment were assessed clinically, haemodynamically and by cardiopulmonary exercise testing for at least 6 months. Upon switching from inhaled to intravenous iloprost all patients improved clinically (NYHA III) while pulmonary vascular resistance (PVR) and right atrial pressure decreased from 2386 +/- 243 to 1381 +/- 124 dyne .s .cm(-5) and 12 +/- 1 to 8.5 +/- 1 mmHg, respectively (both p < 0.05). Despite this acute improvement haemodynamic (PVR increased from 1462+/-223 to 1978 +/- 327 dyne .s .cm(-5)) and clinical (4 deaths, 4 transplantations) deterioration occurred with continued intravenous treatment during the following 6 months., Conclusions: In the group of patients described in this report the clinical and haemodynamic deterioration occurring while on mono therapy with inhaled iloprost could be stopped by switching to continuous application of intravenous iloprost. However, with continued intravenous therapy only a subgroup of patients could clinically be stabilized and transplanted successfully.
