There are about 200 different types of interstitial lung disease (ILD), and a crucial initial step in the assessment of a patient with suspected ILD is achieving an appropriate diagnosis. Some ILDs respond to immunosuppressive agents, while immunosuppression can be detrimental in others, hence treatment is based on the most confident diagnosis with consideration of a patient’s risk factors. Immunosuppressive medications have the potential to result in substantial, and perhaps life-threatening, bacterial infections to a patient. However, data on the risk of bacterial infections from immunosuppressive treatment specifically in patients with interstitial lung disease is lacking. We hereby review the immunosuppressive treatments used in ILD patients excluding sarcoidosis, highlight their risk of bacterial infections, and discuss the potential mechanisms that contribute to the increased risk of infections....
Background: Childhood Tuberculosis (TB) is an important cause of mortality and morbidity, which causes a significant TB burden in developing countries. Objectives: The aim of this study was to describe clinical profile and diagnostic procedures used in outpatient department (OPD) of a tertiary care hospital. Methods: It was a retrospective study conducted in OPD of Paediatrics Department, Bangabandhu Sheikh Mujib Medical University, Shahbag, Dhaka, Bangladesh. Age range of studied populations, 3 months to 18 years who presented with clinical features of TB and were later diagnosed with tuberculosis according to national guidelines for the management of tuberculosis in children, 2021 were enrolled in this study. A total of 108 diagnosed cases of Tuberculosis between August 2021 and July 2022 were enrolled in this study. Data were collected from OPD records and transferred into MS excel sheet for data processing & analysis. Results: Among 834 suspected patients, 108 patients aged 3 months to 18 years were diagnosed with tuberculosis. The highest number of cases 47 (43.51%) were found in 11 - 18 years age group. Gender distribution of the patient showed 58 (53.70%) were male and 50 (46.29%) were female. Among 108 TB cases, 44 (40.74%) were pulmonary TB and 64 (59.25%) were extrapulmonary Tb. Among 64 extrapulmonary TB cases 38 (59.37%) cases were diagnosed as TB lymphadenitis. Fever 83 (76.85%), weight loss 62 (57.4%), cough 50 (46.29%), lump in neck and axilla 38 (35.18%) were found in most of the cases. A positive Mantoux test was found in 68 (62.96%) patients. Chest x-ray findings showed patchy opacity and consolidation in 46 (42.59%) cases. Suggestive FNAC from lymph node was observed among 35 (32.4%) cases. For bacteriological confirmation sputum gene Xpert and stool xpert ultra were positive among 10 (9.25%) and 23 (21.29%) cases. Conclusion: In this study, extrapulmonary TB (EPTB) cases were more than pulmonary TB (PTB) in children. Diagnosis of tuberculosis was based on clinical suspicion supported by various investigations especially bacteriological detection with stool X pert ultra in children....
Personalized treatment of metastatic non-squamous non-small cell lung cancer (NSCLC) requires detailed molecular characterization of the tumour including detection of predictive driver mutations and programmed death ligand 1 (PD-L1) expression. Complete detection is influenced by the amount of tumour cells sampled as well as their quality. Different sampling techniques may be necessary to provide sufficient tumour material for comprehensive molecular characterization. Missing the detection of targetable molecular genetic aberrations would have a serious impact on the quality of life and prognosis of a patient. This case report highlights the importance of biopsy technique in a patient with NSCLC. Several procedures—pleural puncture, transthoracic lung biopsy and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)—could not provide sufficient tumour material for precise tumour characterization. Only the addition of EBUS-guided transbronchial lymph node cryobiopsy (EBUS-TBLNC) enabled complete immunohistochemical and genetic tumour characterization, demonstrating PD-L1 expression in 100% of the tumour cells in the absence of actionable genetic alterations. Based on these results, immunotherapy was initiated....
Introduction: Diaphragm dysfunction is common in patients undergoing mechanical ventilation. The application of positive end-expiratory pressure (PEEP) and the varying endexpiratory lung volume cause changes in diaphragm geometry. We aimed to assess the impact of the level of PEEP and lung inflation on diaphragm thickness, thickening fraction and displacement. Methods: An observational study in a mixed medical and surgical ICU was conducted. The patients underwent a PEEP-titration trial with the application of three random levels of PEEP: 0 cmH2O (PEEP0), 8 cmH2O (PEEP8) and 15 cmH2O (PEEP15). At each step, the indices of respiratory effort were assessed, together with arterial blood and diaphragm ultrasound; end-expiratory lung volume was measured. Results: 14 patients were enrolled. The tidal volume, diaphragm displacement and thickening fraction were significantly lower with higher levels of PEEP, while both the expiratory and inspiratory thickness increased with higher PEEP levels. The inspiratory effort, as evaluated by the esophageal pressure swing, was unchanged. Both the diaphragm thickening fraction and displacement were significantly correlated with inspiratory effort in the whole dataset. For both measurements, the correlation was stronger at lower levels of PEEP. The difference in the diaphragm thickening fraction during tidal breathing between PEEP 15 and PEEP 0 was negatively related to the change in the functional residual capacity and the change in alveolar dead space. Conclusions: Different levels of PEEP significantly modified the diaphragmatic thickness and thickening fraction, showing a PEEP-induced decrease in the diaphragm contractile efficiency. When using ultrasound to assess diaphragm size and function, the potential effect of lung inflation should be taken into account....
This study evaluated the efficacy and safety of pulmonary rehabilitation (PR) on functional performance, exercise-related oxygen saturation, and health-related quality of life among patients with idiopathic pulmonary fibrosis (IPF). Methods: A total of 25 patients with IPF (13 in the PR group and 12 in the non-PR group) were enrolled between August 2019 and October 2021 at Haeundae-Paik Hospital in the Republic of Korea. A cardiopulmonary exercise test (CPET), six-minute walk test (6MWT), pulmonary function test (PFT), Saint George’s Respiratory Questionnaire (SGRQ), muscle strength test, and bioelectrical impedance analysis were performed in each group at baseline and after eight weeks of PR. Results: The mean age was 68 years of age and most subjects were male. Baseline characteristics were similar between the two groups. The distance during 6MWT after PR was significantly improved in the PR group (inter-group p-value = 0.002). VO2max and VE/VCO2 slopes showed a significant difference after eight weeks only in the PR group, but the rate of change did not differ significantly from the non-PR group. Total skeletal muscle mass, PFT variables, and SGRQ scores did not differ significantly between the groups. Conclusions: PR improved exercise capacity, as measured using CPET and 6 MWT. Further studies in larger samples are needed to evaluate the long-term efficacy of PR in IPF patients....
