ABSTRACT

BACKGROUND: Ambroxol has been established for decades in the treatment of acute and chronic respiratory diseases. In 2015, the European Medicines Agency reassessed the clinical benefit-risk ratio of the drug. OBJECTIVE: What new scientific data on ambroxol, which are relevant to the treatment of bronchopulmonary diseases, are available? METHOD: The review is based on a systematic literature research in medline with the search term "ambroxol" during the publication period 2006-2015. Non-relevant publications were excluded manually. RESULTS AND CONCLUSIONS: Ambroxol is still intensively researched. The traditional indication as an expectorant is confirmed. But there is also an ever better understanding of the various mechanisms of action as well as the ever more exact modeling of the structures under investigation. New fields of application are conceivable, e. g. in patients with severe pulmonary disease who undergo surgery or who are in intensive care, as an adjuvant in anti-infective therapies, especially in infections with biofilm-producing pathogens, or in rare diseases such as lysosomal storage diseases. However, final evidence of the clinical relevance in these fields of application is still missing.

ABSTRACT

OBJECTIVE: The objective of our study was to determine whether transbronchial bronchoscopic biopsy of solitary pulmonary nodules under CT guidance using a low-dose protocol can increase diagnostic yield in patients who had undergone unsuccessful conventional bronchoscopic biopsy. SUBJECTS AND METHODS: We included 33 consecutive patients (25 men; mean age +/- SD, 64 +/- 9.6 years) with solitary pulmonary nodules at different sites and with a lesion-to-pleura distance of at least 2 cm who previously underwent conventional bronchoscopy that did not result in histologic diagnosis. All patients were prospectively investigated with transbronchial bronchoscopic biopsy under MDCT guidance. Examinations were performed with the patient in conscious sedation using a low-dose protocol (80 kV, 20 mAs, 5-mm collimation, 10-mm slices). The position of the tip of the biopsy device was confirmed and documented before biopsies were performed. All specimens were examined by standard histopathologic techniques. The effective radiation dose was calculated for every patient. RESULTS: The diagnostic yield was 24 in 33 selected patients (overall accuracy, 72.7%): 13 (54%) had primary lung cancer and 11 (46%) had benign diagnoses. The formal operative characteristics were sensitivity, 59%; specificity, 100%; positive predictive value, 100%; and negative predictive value, 55%. The final diagnoses of the remaining nine patients in whom transbronchial bronchoscopic biopsy was not diagnostic were non-small cell lung cancer (n = 3); small cell lung cancer (n = 3); and alveolar carcinoma, carcinoid tumor, and hemorrhaged bulla (n = 1 each). All nonmalignant diagnoses were confirmed by 6 months radiographic and clinical follow-up. The mean duration of the procedure was 39 +/- 15 minutes, and the average effective dose was 0.7 mSv (range, 0.5-1.1 mSv). One case of pulmonary hemorrhage (3%) occurred after the procedure. CONCLUSION: MDCT-guided transbronchial bronchoscopic biopsy is a promising and safe tool for the diagnostic pathway of solitary pulmonary nodules in previously undiagnosed patients. Image quality was sufficient with low-dose protocols, which resulted in low radiation exposure for patients and personnel.

ABSTRACT

BACKGROUND AND PURPOSE: Obstructive sleep apnea syndrome (OSAS) is regarded as a cardiovascular risk factor. Therefore, cardiopulmonary exercise capacity in patients with OSAS before and under treatment with continuous positive airway pressure (CPAP) was investigated. PATIENTS AND METHODS: Cardiopulmonary exercise capacity was investigated in 36 patients with untreated OSAS using spiroergometry. A follow-up after at least 6 months was performed in 17 of these patients being treated with CPAP and in eight CPAP-neglecting patients, who served as controls. RESULTS: Maximum oxygen uptake ( O(2max)) was significantly reduced in all 36 patients with untreated OSAS (17.68 +/- 6.1 ml/min/kg) compared with reference values (30.72 +/- 4.9 ml/min/kg; p < 0.001). After an average of 305.7 +/- 104.8 nights of CPAP therapy, O(2max) rose from 15.33 +/- 4.8 to 18.53 +/- 6.9 ml/min/kg, whereas O(2max) remained unchanged in controls. Further spirometric parameters of exercise capacity as well as arterial blood pressure were also significantly improved under CPAP therapy. CONCLUSION: Cardiopulmonary exercise capacity is markedly reduced in patients with OSAS. Long-term CPAP therapy leads to a significant improvement of reduced cardiopulmonary exercise capacity in these patients.
