Extracorporeal membrane oxygenation (ECMO) in patients with tuberculosis: systematic review and meta-analysis of 43 cases.

INTRODUCTION: Tuberculosis (TB) is still a major contributor to the global health burden. Pulmonary TB can lead to life-threatening respiratory failure necessitating extracorporeal membrane oxygenation (ECMO) therapy. However, data on ECMO experience in the management of TB patients are scarce. METHODS: We conducted a systematic review of the literature using the search terms ECMO, extracorporeal membrane oxygenation, TB and tuberculosis in three databases (Medline, Web of Science and EMBASE). Clinical data were extracted by two independent investigators. Clinical parameters, such as mode of ECMO therapy, duration of treatment and clinical outcomes, were assessed. RESULTS: Overall, 43 patients from 15 countries were included in the analysis. The age ranged from 0 to 65 years, 39.5% were male, and 60.5% were female. The majority of patients suffered from ARDS (83.4%), with a mean Horovitz quotient of 68.1 (range 30.0-131.0). 83.7% received VV-ECMO, and 24.3% received VA-ECMO. Coinfections and complications were frequently observed (45.5% and 48.6% respectively). At the end of the respective observation period, the overall outcome was excellent, with 81.4% survival. DISCUSSION: ECMO therapy in TB patients appears to be a feasible therapeutic option, providing a bridge until antimycobacterial therapy takes effect. As the underlying cause is reversible, we advocate for the evaluation of ECMO usage in these patients with acute cardiac or respiratory failure.

Differential radiological features of patients infected or colonised with slow-growing non-tuberculous mycobacteria.

Non-tuberculous mycobacterial pulmonary disease (NTM-PD) is considered a growing health concern. The majority of NTM-PD cases in Europe are caused by slow-growing mycobacteria (SGM). However, distinct radiological features of different SGM remain largely uninvestigated. We applied a previously described radiological score to a patient cohort consisting of individuals with isolation of different SGM. Correlations between clinical data, species and computed tomography (CT) features were examined by logistic and linear regression analyses, as well as over the course of time. Overall, 135 pulmonary CT scans from 84 patients were included. The isolated NTM-species were mainly Mycobacterium avium complex (MAC, n = 49), as well as 35 patients with non-MAC-species. Patients with isolation of M. intracellulare had more extensive CT findings compared to all other SGM species (coefficient 3.53, 95% Cl - 0.37 to 7.52, p = 0.075) while patients meeting the ATS criteria and not undergoing therapy exhibited an increase in CT scores over time. This study provides insights into differential radiological features of slow-growing NTM. While M. intracellulare exhibited a tendency towards higher overall CT scores, the radiological features were similar across different SGM. The applied CT score might be a useful instrument for monitoring patients and could help to guide antimycobacterial therapy.

External cephalic version at 38 weeks' gestation at a specialized German single center.

INTRODUCTION: Cesarean section (CS) rates are increasing worldwide. One constant indication is the breech presentation at term. By offering external cephalic version (ECV) and vaginal breech delivery CS rates can be further reduced. OBJECTIVE: This study aimed to analyze the ECV at 38 weeks of gestation with the associate uptake rate, predicting factors, success rate, and complications at a tertiary healthcare provider in Germany specializing in vaginal breech delivery. METHODS: We conducted a prospective cohort study with retrospective data acquisition. All women with a singleton fetus in breech presentation presenting after 34 weeks of gestation for counseling between 2013 and 2017 were included. ECV impact factors were analyzed using logistic regression. RESULTS: A total of 1,598 women presented for breech birth planning. ECV was performed on 353 patients. The overall success rate was 22.4%. A later week of gestation (odds ratio [OR] 1.69), an abundant amniotic fluid index (AFI score) (OR 5.74), fundal (OR 3.78) and anterior (OR 0.39) placental location, and an oblique lie (OR 9.08) were significantly associated with successful ECV in our population. No major complications were observed. The overall vaginal delivery rates could be increased to approximately 14% with ECV. CONCLUSION: The demand for alternative birth modes other than CS for breech birth is high in the area of Frankfurt, Germany. Our study offers evidence of the safety of ECV at 38 weeks. Centers with expertise in vaginal breech delivery and ECV can reduce CS-rates. To further establish vaginal breech delivery and ECV as alternate options, the required knowledge and skill should be implemented in the revised curricula.
