RESUMEN
Tension pneumomediastinum with hemodynamic failure is a rare but life-threatening condition. Rapid decompression of the mediastinum by drainage is essential to save the patient's life. This report presents a case of tension pneumomediastinum that developed during conservative management of a pneumomediastinum associated with idiopathic pulmonary fibrosis. Endoscopically guided mediastinal drainage was successfully performed in the emergency situation of tension pneumomediastinum. Using the semi-flexible fiberscope inserted through a subxiphoid approach, the drainage catheter was easily and safely placed at the appropriate site in the mediastinum. Good mediastinal decompression was achieved, and the patient was out of this critical condition.
RESUMEN
BACKGROUND: Although combination therapy using clarithromycin, rifampicin, and ethambutol is recommended for patients with pulmonary Mycobacterium avium complex (MAC) disease, some patients do not tolerate it because of adverse effects or underlying diseases. The efficacy and safety of fluoroquinolone-containing combination regimens as an alternative remain uncertain. This study aimed to compare the efficacy and safety of fluoroquinolone-containing regimens with those of the standard regimens for treating pulmonary MAC disease. METHODS: We retrospectively included consecutive MAC patients who were treated in our hospital between January 2011 and May 2019. Patients treated with fluoroquinolone-containing regimens who had relapsed after treatment with standard regimens were excluded. A propensity score analysis was conducted to reduce selection bias, and the proportions of clinical improvement, defined by chest imaging findings and sputum conversion, were compared between the fluoroquinolone-containing regimen and standard regimen groups. RESULTS: We analyzed 28 patients who received fluoroquinolone-containing regimens and 46 who received the standard regimen. Fluoroquinolone-containing regimens were more likely selected for patients with cavitary lesions, diabetes mellitus, culture negativity, a low daily physical activity level, a decreased lymphocyte count and an increased CRP level. The propensity score was calculated using these variables (C-statistic of the area under the receiver operating characteristic curve of the propensity score: 0.807, p < 0.0001). The fluoroquinolone-containing regimens were significantly inferior to the standard regimen in clinical improvements (p = 0.002, Log-rank test) in the univariate analysis, but the significance was lost after adjusting for the propensity score (HR 0.553, 95% CI 0.285-1.074, p = 0.080). Six (21%) patients in the fluoroquinolone-containing regimen group and ten (22%) patients in the standard regimen group experienced low-grade adverse effects. CONCLUSIONS: There was no significant difference in clinical improvement between these regimens after propensity score adjustment. A large-scale prospective study is required to validate these results.

INTRODUCTION: Although the aging population had been increasing in many countries, the factors associated with sputum conversion in elderly patients with pulmonary tuberculosis have not been fully elucidated. OBJECTIVES: We aimed to identify the predictors of delayed sputum conversion and to assess the impact of non-conversion on mortality during tuberculosis treatment in elderly patients. METHODS: Elderly patients (>65 years) admitted at our hospital in Japan for sputum smear-positive pulmonary tuberculosis were included. The risk factors for sputum non-conversion after 2 months of treatment were determined using multiple logistic regression. Cox hazard regression was used to assess the influence of non-conversion on mortality. RESULTS: We included 185 patients, with median age of 82 years (IQR, 79-88 years). The median time to conversion was 47 (95% CI 43-51) days, and 62 (34%) were identified as non-converters. Multivariate analysis showed that high pretreatment smear grade, high C-reactive protein level and poor performance status were associated with non-conversion. Non-conversion did not contribute to death during treatment. CONCLUSIONS: In elderly patients, inflammation level and physical activity level, along with initial smear grade may have a significant impact on delayed sputum conversion. Non-conversion after two months of treatment might not be related with mortality.

While advanced age is a main prognostic factor in patients with tuberculosis, the factors that specifically affect tuberculosis-related death are unclear because elderly people are at a risk for other age-related lethal diseases. We aimed to assess the impact of performance status on tuberculosis-related death among elderly patients with lung tuberculosis. Elderly patients (≥65 years of age) admitted to our hospital for bacteriologically-diagnosed lung tuberculosis were included, and analyzed the influence of performance status on tuberculosis-related in-hospital death, with non-tuberculosis-related death as a competing risk. Forty and 19 of the 275 patients died from tuberculosis-related causes and non-tuberculosis-related causes, respectively. The tuberculosis-related death group had a greater number of patients with a poor performance status (defined as category 3 and 4 [HR 21.022; 95%CI 2.881-153.414; p = 0.003]), a lower serum albumin level (HR 0.179; 95%CI 0.090-0.359; p < 0.001) and a higher C-reactive protein level (HR1.076; 95%CI 1.026-1.127; p = 0.002). A multivariate competing risk regression analysis showed that a poor performance status (HR 7.311; 95%CI 1.005-53.181; p = 0.049) and low albumin level (HR 0.228; 95%CI 0.099-0.524); p = 0.001) significantly predicted tuberculosis-related death. Performance status can be a useful scale for predicting tuberculosis-related death among elderly patients with pulmonary tuberculosis.

BACKGROUND: Unusual radiological images may delay diagnosis of pulmonary tuberculosis. This study aimed to analyze the risk factors for an atypical radiological image in patients with pulmonary tuberculosis. METHODS: We retrospectively analyzed data from patients admitted to one hospital from January 2013 to December 2016 for sputum smear-positive lung tuberculosis who underwent chest computed tomography (CT) on admission. Patients whose sputum cultures were positive for general bacteria were excluded. Patient characteristics and laboratory data were compared between patients with cavity and those without and between patients with upper predominant lung involvement and those without. RESULTS: This study included 94 (93%) of 101 patients who underwent chest CT. The non-cavity group was older, had a greater number of females, had a lower C-reactive protein (CRP) level, and had a lower glomerular filtration rate. Multivariate analysis showed that a low CRP level (OR 0.808; 95% CI 0.674-0.967; p = 0.020) significantly predicted non-cavity pulmonary tuberculosis. The non-upper predominant lung involvement group was older and had a greater number of females, poorer performance status, a higher CRP level, and a lower serum albumin level. A poor performance status (OR 2.155; 95% CI 1.257-3.693; p = 0.005) was found to significantly predict pulmonary tuberculosis with non-upper predominant lung distributions. CONCLUSIONS: A low CRP level and poor performance status were associated with non-cavity and non-upper predominant lung distribution, respectively, in patients with pulmonary tuberculosis. Tuberculosis patients with these characteristics may present unusual chest images.

Whether or not additional antibiotics with anti-tuberculosis agents are required to treat bacterial co-infection with pulmonary tuberculosis is unclear. We aimed to assess the impact of additional antibiotics on mortality in pulmonary tuberculosis patients whose sputum cultures were positive for general bacteria as a surrogate definition of bacterial pneumonia. This study was a single-center retrospective cohort using a propensity score analysis. We included patients who were admitted for pulmonary tuberculosis and whose sputum cultures were positive for general bacteria. The mortality of patients who received additional antibiotics was analyzed after adjusting for other variables, including the propensity score predicting treatment with additional antibiotics. We assessed 68 and 55 tuberculosis patients treated with and without general antibiotics, respectively. Additional antibiotics tended to be administered to patients with a high level of C-reactive protein and neutrophil count, poor performance status, hypoxemia and hypoalbuminemia (C-statistics of area under receiver operating characteristic curve to the propensity score; 0.884, p < 0.001). In the multivariate analysis, advanced age and not the use of additional antibiotics was associated with in-hospital mortality. Additional antibiotics with anti-tuberculosis agents may not improve the prognosis of pulmonary tuberculosis patients whose sputum cultures were positive for general bacteria. Isolation of general bacteria does not equate to complication with bacterial pneumonia, so physicians should not administer general antibiotics to TB patients based solely on the results of sputum culture for general bacteria. A prospective study is needed to verify these results using a more accurate definition of pulmonary tuberculosis complicated with bacterial pneumonia.

BACKGROUND: While advanced age has been suggested as a prognostic factor in patients with tuberculosis, the characteristics associated with a poor outcome in elderly patients have remained unclear. The aim of this systematic review was to describe the risk factors for a poor outcome in elderly patients with tuberculosis. METHODS: We identified 1255 studies published between 1919 and 2017 from the PubMed database by using combinations of the keywords "tuberculosis [Title/Abstract]" and "elderly [Title/Abstract]". Full texts of the studies that met the inclusion criteria were further evaluated by two independent investigators. RESULTS: even retrospective cohort studies were included in this systematic review. More advanced age, comorbidities, and nutritional status were likely to be prognostic factors in Taiwan (aging country) and Japan (super-aged country), while human immunodeficiency virus infection and severe tuberculosis were associated with a poor outcome in low-income countries. Two studies from Taiwan investigated the prognostic factors of tuberculosis-specific death and non-tuberculosis-specific death separately, but no significant differences were found in the factors between the two types of death. CONCLUSIONS: The prognostic factors of tuberculosis in elderly patients varied according to the income levels of the countries. The factors in Taiwan and Japan were mainly associated with host factors, irrespective of the cause of death, which may reflect senile deterioration due to old age.
