Abstract
The 2015 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension are also valid for Germany. The guidelines contain detailed information about the clinical classification and diagnosis of pulmonary hypertension, and furthermore provide novel recommendations for risk stratification and follow-up assessments. 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 the clinical classification and initial diagnosis of PH. This article summarizes the results and recommendations of this working group.

Abstract
We investigated the giant resonance in xenon by high-order harmonic generation spectroscopy driven by a two-color field. The addition of a nonperturbative second harmonic component parallel to the driving field breaks the symmetry between neighboring subcycles resulting in the appearance of spectral caustics at two distinct cutoff energies. By controlling the phase delay between the two color components it is possible to tailor the harmonic emission in order to amplify and isolate the spectral feature of interest. In this Letter we demonstrate how this control scheme can be used to investigate the role of electron correlations that give birth to the giant resonance in xenon. The collective excitations of the giant dipole resonance in xenon combined with the spectral manipulation associated with the two-color driving field allow us to see features that are normally not accessible and to obtain a good agreement between the experimental results and the theoretical predictions.

Abstract
OBJECTIVES While idiopathic pulmonary arterial hypertension (PAH) is a rare disease, it is seen more frequently in patients with HIV infection. The aim of this study was to evaluate the prevalence of pulmonary hypertension (PH) in patients with HIV infection by echocardiographic screening. METHODS Echocardiography and N-terminal of the prohormone brain natriuretic peptide measurement were used to examine the prevalence of PH prospectively in HIV-positive patients (n = 374) during routine follow-up visits for HIV disease. RESULTS In echocardiographic screening, PH was detected in a total of 23 of 374 HIV-infected patients (6.1%). Of these, three patients (13%) presented with symptoms of dyspnoea and fatigue, and diagnosis of PAH was confirmed by right heart catheterization. Patients with systolic pulmonary artery pressure (sPAP) > 30 mmHg were more likely to be female, to have a history of injecting drug use and to originate from high-prevalence countries (HPCs). CONCLUSIONS Echocardiographic screening detected PH in a substantial proportion of HIV-positive patients. Female gender, a history of injecting drug use and HPC origin were associated with a higher prevalence of HIV-associated PH. The relevance and long-term outcome of these findings need to be validated in follow-up studies, which are ongoing.

Abstract
HISTORY AND ADMISSION FINDINGS A 49-year-old patient was admitted to our ward because of a troponin elevation (non ST-elevation myocardial infarction) following a rhinoscopy in an external hospital. The patient complained of typical angina, chronic rhinitis and epistaxis. Analysis of the nasal biopsy had shown the histological finding of granulomatosis with polyangiitis (Wegener's granulomatosis). INVESTIGATION The consecutively performed catheterization showed a coronary one-vessel disease without significant stenosis. Echocardiography showed diastolic dysfunction as well as hemodynamically not significant pericardial effusion. The MRI scan of the heart revealed multiple myocardial scars located ventricular apical and septal. Extended bilateral pulmonary opacities in the thoracic CT scan, microhematuria, leukocyturia and proteinuria indicated multi-organ involvement of the small vessel disease. TREATMENT AND COURSE The patient's condition improved quickly in response to steroids and cyclophosphamide, followed by attenuation of clinical symptoms and normalizing blood and renal parameters. CONCLUSION The prognosis of granulomatosis with polyangiitis is mainly limited by renal and pulmonal involvement. Cardiac involvement is commonly rare and associated with clinical courses refractory to immunosuppressive therapy. Generally, all cardiac structures can be affected, thereby impending serious cardiac events. Normally, granulomatosis with polyangiitis responds quickly to immunosuppressive therapy, associated with a rather good prognosis without higher mortality.

Abstract
HISTORY AND ADMISSION FINDINGS A 53-year-old woman was admitted to our chest pain unit because of an acute coronary syndrome (non ST-elevation myocardial infarction). She complained of asthma, chronic sinusitis and involuntary weight loss, occasional fever and night sweats over the past six months. INVESTIGATIONS Coronary angiography did not show any signs of macroscopic coronary artery disease, while echocardiography demonstrated a hemodynamically not significant pericardial effusion. Magnetic resonance imaging of the heart revealed a subendocardial scar, extension and localization pointing to a vascular genesis. Thoracic computed tomography revealed pulmonary opacities and blood tests showed an eosinophilia, leading to the clinical diagnosis of Churg-Strauss syndome. TREATMENT AND COURSE The patient responded quickly to oral steroids, and blood parameters returned to normal. CONCLUSION Acute coronary syndrome in youngish patients without classical cardiovascular risk factors is suggestive for myocarditis but also for vasculitis. Churg-Strauss syndrome usually responds quickly to immunosuppressive therapy, associated with a rather good prognosis without high mortality.

Abstract
HISTORY Within three months, three patients with end-stage renal disease presented for evaluation of pulmonary hypertension (PH): a 72-year-old woman (case 1), a 67-year-old patient (case 2) and a 75-year-old patient (case 3), each with increasing dyspnea (WHO functional class III). INVESTIGATIONS In all three cases, there was echocardiographic evidence of right heart failure; right heart catheterization was completed before and after dialysis. In case 1, we found a postcapillary PH (PH group 2 - PH with left heart diseases/diastolic dysfunction). Case 2 also showed a postcapillary PH and a high cardiac output of 9.7 l/min. In case 3, unmasked after dialysis, a precapillary, pulmonary arterial hypertension (PAH - group 1) was detected. TREATMENT AND COURSE In patient 1, no relevant improvement of symptoms was observed, despite optimized cardiac therapy. There was a significant clinical improvement in patient 2 after surgical reduction of the arteriovenous shunt. In patient 3, relevant clinical and hemodynamic improvement was seen under treatment with bosentan. CONCLUSION These cases confirm the role of right heart catheterization in the differential diagnosis of unclear PH in patients with end-stage renal failure. Moreover, the three cases point to three different causes. Specific therapies can result in significant symptomatic improvement.

Abstract
Study objective The pathogenesis of chronic obstructive pulmonary disease (COPD) is characterized by an interaction of environmental influences, particularly cigarette smoking, and genetic determinants. Given the global increase in COPD, research on the genomic variants that affect susceptibility to this complex disorder is reviving. In the present study, we investigated whether single nucleotide polymorphisms in 'a disinter-grin and metalloprotease' 33 (ADAM33) are associated with the development and course of COPD. Patients and design We genotyped 150 German COPD patients and 152 healthy controls for the presence of the F+1 and S_2 SNPs in ADAM 33 that lead to the base pair exchange G to A and C to G, respectively. To assess whether these genetic variants are influential in the course of COPD, we subdivided the cohort into two subgroups comprising 60 patients with a stable and 90 patients with an unstable course of disease. Results In ADAM33, the frequency of the F+1 A allele was 35.0% among stable and 43.9% among unstable COPD subjects, which was not significantly different from the 35.5% found in the controls (P = 0.92 and P = 0.07, respectively). The frequency of the S_2 mutant allele in subjects with a stable COPD was 23.3% (P = 0.32), in subjects with an unstable course 30.6% (P = 0.47). Conclusion The study shows that there is no significant difference in the distribution of the tested SNPs between subjects with and without COPD. Furthermore, these polymorphisms appear to have no consequences for the stability of the disease course.

Abstract
Study objective The etiology of chronic obstructive lung disease (COPD) is unclear. It is supposed to be the product of an exogenous antigenic stimulus, such as tobacco smoke, and an endogenous genetic susceptibility. The angiotensin-converting enzyme (ACE) gene contains a polymorphism based on the presence (insertion [I]) or absence (deletion [D]) of a 287-bp nonsense domain, resulting in three different genotypes (II, ID and DD). The aim of the study was to find out whether the ACE gene polymorphism can determine the course of COPD. Patients and design We genotyped 152 Caucasian patients with COPD and 158 healthy controls for the ACE (I/D) polymorphism. We divided the COPD group into one group of 64 patients with a stable course of disease, defined as less than three hospitalizations over the last three years due to COPD, and another group of 88 patients with an instable course with more than three hospitalizations. Results The I-allele was significantly associated with an increased risk for COPD in a dominant model (OR 1.67 (95% CI 1.00 to 2.78), p = 0.048), but not in a recessive or co-dominant model. Moreover, the I-allele of ACE (I/D) was significantly increased in patients with a stable course of COPD (p = 0.012) compared with controls. In a dominant model (II/ID v DD) we found an even stronger association between the I-allele and a stable course of COPD (OR 3.24 (95% CI 1.44 to 7.31), p = 0.003). Conclusion These data suggest that the presence of an ACE I-allele determines a stable course of COPD.

Abstract
HISTORY AND CLINICAL FINDINGS A 58-years-old non-smoking woman presented at our Thoracic Centre with increasing exertional dyspnea and on examination was found to have wheezing and decreased breath sounds over the left lung. INVESTIGATIONS Chest X-ray revealed an atelectasis of the left anterobasal lung segment. Computed tomography revealed a 3.5 cm mass at the left inferior lobe. Bronchioscopy showed a total occlusion of the segmental bronchus because of an endobronchial tumor. Histology of a biopsy showed the tumor to be a carcinoid. Staging by whole-body ocreotide scintigraphy showed no evidence of metastases. TREATMENT AND COURSE The patient recovered quickly from resection of the left inferior lobe and radical lymphadenectomy. Two years later, she has remained free of symptoms and without evidence of recurrence. CONCLUSIONS Although rare (ca. 1.0 % of all primary lung tumors), the differential diagnosis of dyspnea and uniliteral wheezing should include a bronchial carcinoid. It is a potentially curable tumor, if detected and treated early. An interdisciplinary approach is pivotal to its perioperative management.

Abstract
8047 Background: Elderly pts receiving chemotherapy are more likely to have febrile neutropenia and infection than younger pts. Prophylactic fluoroquinolone during chemotherapy reduces the rate of infection and hospitalization vs placebo. The effect of prophylactic treatment with the fluoroquinolone, levofloxacin, on infection rates and survival during docetaxel plus carboplatin therapy was assessed in elderly pts with advanced NSCLC. Methods: In this randomized, double-blind, placebo-controlled Phase III study, eligible pts were aged ≥65 years with previously untreated, histologically/cytologically proven stage IIIB/IV NSCLC, and normal cardiac, renal, hepatic, and hematologic function. Active infection or antibiotics 72 hours before inclusion was not permitted. A planned sample size of 192 pts was considered sufficient for analysis. Pts were randomized to docetaxel (75 mg/m2 IV, Day 1) plus carboplatin (AUC 6 IV, Day 1) q3w, plus placebo or levofloxacin (500 mg po, once daily) on Days 5–11. Primary endpoint was grade 3/4 infection rate or systemic antibiotic therapy of grade 1/2 infection rate. Secondary endpoints were progression free-survival and overall survival. Between-group comparisons were performed using Fisher's exact test. Results: 192 pts (median age 70 years; ECOG PS 0/1/2 in 36%/55%/9%) were randomized to docetaxel plus carboplatin and levofloxacin (n=99) or placebo (n=93); 5 pts received no treatment and were excluded from the ITT population. Rate of grade 3/4 infection was 27.5% (95% CI: 19.3–39.0%) with levofloxacin vs 36.7% (95% CI: 27.1–48.0%) with placebo. Median progression-free survival (PFS) for patients in the levofloxacin arm was 165 days compared with 121 days in the placebo arm (p=0.22). Median overall survival was comparable between groups (307 vs 314 days, respectively; p=0.28). Conclusions: Levofloxacin prophylaxis reduces the rate of grade 3/4 infection compared with placebo.

Abstract
Single nucleotide polymorphisms in the BTLN2 gene have been recently associated with the risk for sarcoidosis. We now aimed to study additional genetic alterations in BTLN2 as putative genetic risk. The CNV_ID 507, which was highlighted for its possible involvement in sarcoidosis because of its partly deletion of the BTNL2 gene, was tested for association in a cohort of 89 sarcoidosis patients and 89 matched controls, but our results indicated that CNV_ID 507 does not affect the genomic structure of BTLN2 as previously described. Additionally, we identified a heterozygous 1 bp deletion in exon 3, c.450delC. We genotyped 210 patients and 201 controls for c.450delC and observed similar genotype frequencies in both groups without a significant difference (P = 0.4996).

A novel stop mutation truncating critical regions of the cardiac transcription factor NKX2-5 in a large family with autosomal-dominant inherited congenital heart disease. Clin Res Cardiol 2007; 97:39-42.

Abstract
We report on a familial screen of five female members in three generations affected by an autosomal-dominant inherited atrioventricular (AV) conduction block associated with atrial septal defects (ASD) and other congenital cardiovascular diseases (CCVD), such as pulmonary artery stenosis (PAS), patent foramen ovale (PFO) and ventricular septal defect (VSD). We tested the cardiac transcription factor NKX2-5 which is known to cause CCVD with variable phenotype and penetrance by direct sequencing of the two NKX2-5 coding exons in the index patient and identified a novel heterozygous c.325G> T mutation in exon 1 of the gene. This mutation co-segregated with the disease in the family and was present in all five affected family members, but not in 100 control chromosomes. The c.325G > T mutation is predicted to introduce a stop codon at amino-acid position 109 (p.E109X). The truncated protein lacks all of the functionally important domains of the cardiac transcription factor. Therefore, it is very likely that this novel mutation causes a complete loss of NKX2-5 function and haploinsufficiency is the pathophysiological mechanism underlying the disease in the family.
