[Puzzling B symptoms in a 61-year-old patient under treatment for rheumatoid arthritis]. / Rätselhafte B-Symptomatik bei einem 61-Jährigen unter Therapie einer rheumatoiden Arthritis.

A patient with rheumatoid arthritis and immunosuppression developed symptoms of wasting, neuropathy and lung cavitations eventually leading to central nervous system symptoms and fatal multi-organ failure. Disseminated infection with Histoplasma capsulatum proved to be the underlying cause. The primary infection had apparently been acquired 4 years earlier on a holiday to the Caribbean. Rare infectious diseases should be considered in patients under immunosuppression and travel activities to specific endemic areas.

[Differential Diagnosis of Pulmonary Hypertension Using the Example of Collagenosis-associated PAH in the Context of Chronic Lung and Left Heart Disease]. / Differenzialdiagnostik der pulmonalen Hypertonie am Beispiel der Kollagenose assoziierten PAH im Kontext chronischer Lungen- und Linksherzerkrankungen.

Pulmonary hypertension (PH) can be diagnosed in the context of connective tissue diseases (CTD) as well as in elderly patients with multiple comorbidities. A correct clinical differential diagnosis and classification is essential before adequate therapeutic decisions can be made. Differential diagnosis of PH in CTD comprises associated pulmonary arterial hypertension (APAH), group 2 or 3 PH (PH arising from left heart or chronic lung disease), chronic thromboembolic PH (PH) and group 5 (e. g. in the context of terminal renal insufficiency). This is also true of elderly patients in whom the decision has to be made if the increasing number of coincident diseases lead to PH or have to be interpreted as comorbidities. In this manuscript, the differential diagnosis of PH is elucidated, focusing on CTD, in the context of left heart disease and chronic lung disease. Furthermore, criteria are presented facilitating an objective approach in this context.

[Current Aspects of Definition and Diagnosis of Pulmonary Hypertension]. / Aktuelle Definition und Diagnostik der pulmonalen Hypertonie.

At the 6th World Symposium on Pulmonary Hypertension (WSPH), which took place from February 27 until March 1, 2018 in Nice, scientific progress over the past 5 years in the field of pulmonary hypertension (PH) was presented by 13 working groups. The results of the discussion were published as proceedings towards the end of 2018. One of the major changes suggested by the WSPH was the lowering of the diagnostic threshold for PH from ≥ 25 to > 20 mmHg mean pulmonary arterial pressure, measured by right heart catheterization at rest. In addition, the pulmonary vascular resistance was introduced into the definition of PH, which underlines the importance of cardiac output determination at the diagnostic right heart catheterization.In this article, we discuss the rationale and possible consequences of a changed PH definition in the context of the current literature. Further, we provide a current overview on non-invasive and invasive methods for diagnosis, differential diagnosis, and prognosis of PH, including exercise tests.

[General and supportive therapy of pulmonary arterial hypertension]. / Allgemeine und supportive Therapie der pulmonal arteriellen Hypertonie: Empfehlungen der Kölner Konsensus Konferenz 2016.

The 2015 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension are also valid for Germany. The guidelines contain detailed recommendations for the targeted and supportive treatment of pulmonary arterial hypertension (PAH). However, the practical implementation of the European Guidelines in Germany requires the consideration of several country-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 2016, 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 general and supportive therapy of PAH. This article summarizes the results and recommendations of this working group.

[Pulmonary hypertension due to chronic lung disease: Recommendations of the Cologne Consensus Conference 2016]. / Pulmonale Hypertonie bei Lungenkrankheiten: Empfehlungen der Kölner Konsensus-Konferenz 2016.

The 2015 European Guidelines on Pulmonary Hypertension did not cover only pulmonary arterial hypertension (PAH) but also some aspects of pulmonary hypertension (PH) associated with chronic lung disease. The European Guidelines point out that the drugs currently used to treat patients with PAH (prostanoids, endothelin receptor antagonists, phosphodiesterase-5 inhibitors, sGC stimulators) have not been sufficiently investigated in other forms of PH. Therefore, the European Guidelines do not recommend the use of these drugs in patients with chronic lung disease and PH. This recommendation, however, is not always in agreement with medical ethics as physicians feel sometimes inclined to treat other form of PH which may affect quality of life and survival of these patients in a similar manner. To this end, it is crucial to consider the severity of both PH and the underlying lung disease. In June 2016, 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, to discuss open and controversial issues surrounding the practical implementation of the European Guidelines. Several working groups were initiated, one of which was dedicated to the diagnosis and treatment of PH in patients with chronic lung disease. The recommendations of this working group are summarized in the present paper.

[Therapy of Pulmonary Arterial Hypertension]. / Therapie der pulmonal arteriellen Hypertonie.

Pulmonary hypertension (PH) is classified into five distinct groups according to the fifth world conference in Nice 2013. Pulmonary arterial hypertension (PAH) comprises idiopathic PAH, hereditary PAH, drug-induced and associated PAH. Right heart catheterization is essential for the diagnosis of PH and should precede initiation of a targeted PAH therapy. Besides general measures and supportive therapy, four different classes of targeted drugs have been approved for the treatment of PAH. Combination therapy, either sequential or initial (up-front), is increasingly gaining recognition. Risk stratification and treatment goals have been defined to guide therapeutic decisions. However, cure is still far from reach and lung transplantation is an important treatment option for patients with end-stage disease under optimal supportive and targeted drug therapy.

[Pulmonary hypertension: Possible genetic causes and therapeutic options]. / Pulmonale Hypertonie : Mögliche genetische Ursachen und therapeutische Optionen.

Pulmonary hypertension (PH) is a severe disease, which is usually only recognized at a late stage. It is characterized by dyspnea and right heart insufficiency. In some forms of pulmonary hypertension, such as the rare pulmonary arterial hypertension (PAH) and PAH associated with congenital heart defects, genetic factors have been identified. This article summarizes the general and supportive therapies for PH, targeted pharmaceutical treatment for PAH and non-operable chronic thromboembolic pulmonary hypertension. To achieve acceptable survival rates, it is essential to transfer patients to an expert center at an early stage for further differential diagnostics and therapy.

[Dyspnoea in Patients with Pulmonary Hypertension (PH) - a Survey in Spezialized German PH Centres]. / Dyspnoe bei Patienten mit Pulmonaler Hypertonie (PH) - Ergebnisse einer Befragung in deutschen PH-Zentren.

Dyspnoea is the predominant symptom in patients with pulmonary hypertension (PH) at diagnosis. However, since dyspnoea is nonspecific and often occurs in a number of common diseases, the presence of PH can easily be underdiagnosed.In addition, this symptom underlies a high variability in the subjective perception, therefore further diagnostic procedures are often delayed by the patients.A survey of the incidence and severity of dyspnoea in 372 patients with PAH was conducted by questionnaire in German centres. Age, sex distribution and the range of comorbidities corresponded to the findings of national and international registries.Approximately 99 % of patients reported the presence of dyspnoea on exertion, even at low loads.Remarkably, in 13 % of patients dyspnoea occurs as a paroxysmal symptom, which may lead to the differential diagnosis of bronchial asthma. In addition, the patients who were being followed in specialized PH centres reported an increase in dyspnoea during the last year.The results of the survey on the incidence of dyspnoea in patients with PAH are consistent with the findings of international studies.

[Riociguat: stimulator of soluble guanylate-cyclase. New mode of action for the treatment of pulmonary arterial and non operable chronic thromboembolic pulmonary hypertension]. / Riociguat: Stimulation der löslichen Guanylatzyklase. Neuer Wirkmechanismus zur Behandlung der pulmonal-arteriellen und der nicht operablen chronisch thromboembolischen pulmonalen Hypertonie.

Riociguat is the first clinically available soluble Guanylate-cyclase stimulator (sGC) and representative of a completely new class of drugs. Riociguat is approved for pulmonary arterial hypertension (PAH) and non-operable or recurrent/persistent chronic thromboembolic pulmonary hypertension (CTEPH). Moreover, Riociguat is currently under investigation for a wider spectrum of diseases. This article focusses on its mode of action and clinical trial data. Finally, based on these data, the status of approval, as well as the costs a proposal is given how Riociguat can be integrated in the current treatment of PAH and CTEPH.

Radiologic management of haemoptysis: diagnostic and interventional bronchial arterial embolisation.

UNLABELLED: Hemoptysis can be a life-threatening pulmonary emergency with high mortality, is symptomatic of an underlying severe pulmonary disease and requires immediate diagnosis and treatment. Diagnostically, bronchoscopy, conventional chest x-ray and contrast-enhanced multislice computed tomography (MSCT) with CT angiography (CTA) provide information regarding the underlying pulmonary disease, bleeding site, the vascular anatomy of the bronchial arteries (BA) and extrabronchial branches, as well a basis for planning of endovascular intervention. Therapeutically, bronchial artery embolization (BAE) is a safe and effective technique in the hands of an experienced interventionist with profound knowledge of the BA anatomy and possible pitfalls as well as experience with first-line therapy of recurrent and massive hemoptysis or as an intervention prior to elective surgery. Recurrent episodes of hemoptysis are not uncommon and require a prompt repeat BAE after exclusion of extrabronchial systemic and pulmonary artery bleeding sources. This review article should give an overview of the history, anatomical and pathophysiological basics and the clinical context of hemoptysis and diagnosis, as well as a survey of management, treatment and results of BAE. KEY POINTS: Hemoptyses are life threatening and require urgent diagnostic and therapy. Chest x-ray, bronchoscopy, and contrast-enhanced MSCT with CTA should be carried out before therapeutic bronchial artery embolization (BAE). BAE for the treatment of massive and recurrent hemoptysis is safe and effective. False embolization in spinal branches of BA are the most serious complication of a BAE. Repeatedly BAE refractory cases should undergo elective surgery.
