RESUMEN
A tuberculous aneurysm is an uncommon extrapulmonary tuberculosis and is usually fatal. The best way to treat it involves a combination of open surgery and medical treatment. However, it can be challenging to diagnose a tuberculous aneurysm. In this report, we describe a patient with a tuberculous aneurysm who was treated with stent-graft replacement and CT-guided biopsy for diagnosis, followed by nine months of anti-tuberculosis therapy. Despite one week of anti-tuberculous therapy, her fever persisted. A CT scan revealed new, well-defined nodules measuring 1-2mm in the lungs and hepatomegaly, indicating complications of miliary tuberculosis. After three weeks after the CT-guided biopsy, Mycobacterium tuberculosis grew from the arterial wall tissue, leading to the diagnosis of a tuberculous aneurysm complicated by miliary tuberculosis. The patient's aneurysm disappeared on follow-up CT scans, and the patient has been under observation for five years without a relapse. This rare case of tuberculous aneurysm can provide lessons for countries with a low prevalence of tuberculosis. This suggests the possibility of treatment with stent-graft replacement and anti-tuberculous medication and the usefulness of CT-guided biopsy for microbiological and pathological diagnosis.
RESUMEN
Rationale: The long-term effects of using a high-flow nasal cannula for chronic hypercapnic respiratory failure caused by chronic obstructive pulmonary disease remain unclear. Objectives: To assess whether long-term high-flow nasal cannula use reduces the number of exacerbations and improves other physiological parameters in patients with chronic hypercapnic respiratory failure caused by chronic obstructive pulmonary disease. Methods: We enrolled 104 participants (aged ⩾40 yr) with daytime hypercapnia (Global Initiative for Chronic Obstructive Lung Disease stages 2-4) receiving long-term oxygen therapy (⩾16 h/d for ⩾1 mo) and randomly assigned them to high-flow nasal cannula/long-term oxygen therapy and long-term oxygen therapy groups. The primary endpoint was the moderate or severe exacerbation rate. We compared changes from baseline in arterial blood gas values, peripheral oxygen saturation, pulmonary function, health-related quality-of-life scores, and the 6-minute-walk test. Measurements and Main Results: High-flow nasal cannula use significantly reduced the rate of moderate/severe exacerbations (unadjusted mean count 1.0 vs. 2.5, a ratio of the adjusted mean count between groups [95% confidence interval] of 2.85 [1.48-5.47]) and prolonged the duration without moderate or severe exacerbations. The median time to first moderate or severe exacerbation in the long-term oxygen therapy group was 25 (14.1-47.4) weeks; this was not reached in the high-flow nasal cannula/long-term oxygen therapy group. High-flow nasal cannula use significantly improved health-related quality of life scores, peripheral oxygen saturation, and specific pulmonary function parameters. No safety concerns were identified. Conclusions: A high-flow nasal cannula is a reasonable therapeutic option for patients with stable hypercapnic chronic obstructive pulmonary disease and a history of exacerbations.

A 59-year-old man was admitted to our hospital with dyspnea and cough. A large polypoid tumor was observed in the lower trachea and bronchoscopic polypectomy was performed using a snare to relieve symptoms. The tumor was diagnosed as a high grade mucoepidermoid carcinoma mainly by the histology of piecemeal specimens obtained by bronchoscopic resection. The primary lesion involved the trachea and the main bronchus, and there were multiple metastases in the lung. The patient was treated with the combination of carboplatin and paclitaxel. After four cycles of chemotherapy, the tumors were significantly reduced. He remains well without evidence of tumor progression for 25 months. This case suggests that the combination chemotherapy of carboplatin and paclitaxel can be an option for treatment of pulmonary mucoepidermoid carcinoma.

BACKGROUND: COVID-19 incidence is high in patients with cancer. The fatality rate was high for the Delta variant, necessitating infection prevention by vaccination. This study evaluated the safety of a SARS-CoV-2 vaccine in patients with advanced lung cancer receiving anticancer therapy. METHODS: We prospectively enrolled patients receiving anticancer drugs for advanced lung cancer and planning SARS-CoV-2 vaccination. Early side effects within 7 days of vaccination were evaluated using patient-reported outcome (PRO) surveys. Chi-square test and multivariate logistic regression analyses were used. RESULTS: Post-vaccination PROs were collected from 406 patients (252 were males). The mean age was 72 years. Treatment at the time of initial vaccination included chemotherapy, immune checkpoint inhibitors (ICI), a combination of chemotherapy and ICI, targeted therapy including tyrosine kinase inhibitors, and others in 115, 93, 45, 147, and six cases, respectively. The vaccines administered were BNT162b2 and mRNA273 in 361 and three cases, respectively and unknown in 42 cases. A total of 16.1% of patients developed fever (38°C) after the second mRNA vaccination (95% confidence interval: 12.6%-20.1%). This rate is comparable to data previously reported in 120 patients and slightly higher than that of healthy participants of the BNT162b2 study. Patients receiving treatment with cytotoxic anticancer agents were more likely to have high fever. Multivariate analysis showed no correlation between fever frequency and patient background. No serious initial adverse events due to vaccination were observed. CONCLUSIONS: Anti-SARS-CoV-2 mRNA vaccination is safe; however, post-vaccination fever is more common in patients undergoing lung cancer treatment than in healthy individuals.

An 80-year-old woman who had been diagnosed with an endobronchial carcinoid tumor visited our hospital for treatment with an endoscopic technique. However, a bronchoscopic examination at our hospital showed spontaneous regression of the tumor at the orifice of the right middle lobar bronchus. Chest computed tomography five months later revealed no local recurrence. This is the second report of an endobronchial carcinoid tumor vanishing after an endoscopic biopsy.

Allergic bronchopulmonary aspergillosis (ABPA) is an allergic reaction caused by the fungus Aspergillus, and it is often treated with steroids or antifungal agents. However, long-term use of these medications can lead to infections and drug interactions. We present the case of a 71-year-old woman with ABPA who was diagnosed with hepatitis B and active hepatitis C, and sputum analysis revealed the presence of bacteria. Oral steroids were initially administered, but the patient was switched to mepolizumab because of numerous infectious complications. The early introduction of mepolizumab is effective in patients with ABPA complicated by infectious diseases.
RESUMEN
BACKGROUND: Combination therapy with immune checkpoint inhibitors (ICIs) and chemotherapy (ICI + chemotherapy) has become the standard first line treatment for driver oncogene-negative advanced non-small-cell lung cancer (NSCLC). However, it may be more toxic compared to monotherapy, which limits its use. Moreover, the feasibility of the combination therapy in clinical practice remains unknown. METHODS: We conducted a cohort study to determine the implementation rate of ICI + chemotherapy in clinical practice. We retrospectively reviewed clinical data from advanced NSCLC patients who received systemic therapy at 13 institutions between December 2018 and December 2020. RESULTS: After excluding 154 patients with epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) gene alterations, a total of 919 NSCLC patients were included. Among them, 442 were treated with ICI + chemotherapy (48%), whereas 477 were treated with other therapies (52%). Among these 477 patients, 340 did not receive ICI + chemotherapy because of intolerance (71%); thus, more than one-third of the advanced NSCLC patients do not benefit from the combination therapy due to intolerance. Among the 659 NSCLC patients for whom PD-L1 was < 50% or unknown, only 342 received the ICI + chemotherapy combination (52%) even though it is considered preferable to either therapy alone; the remaining 318 patients were treated with other therapies (48%). Among the 318 patients who did not receive ICI + chemotherapy, 274 were intolerant to it (86%). CONCLUSION: Our results revealed that a substantial proportion of advanced NSCLC patients did not benefit from ICI + chemotherapy due to intolerance. As treatments for NSCLC are moving toward combinations for greater efficacy, their feasibility in clinical practice must be taken into consideration.

Dialysate leakage is one of the causes of peritoneal dialysis (PD)-related peritonitis. The rate of catheter removal in PD-related peritonitis caused by dialysate leakage (PDPDL) is high, and the correct treatment is unclear. We experienced a case of PDPDL that was treated with intravenous and intraperitoneal antibiotic therapy. A 44-year-old Japanese man had high glucose discharge from the exit site after 14 days of initiating PD, and he had a fever and cloudy effluent with a high white cell count. We diagnosed him with PDPDL and began to administer vancomycin and ceftazidime intraperitoneally. However, the peritonitis could not be ameliorated. A culture examination showed Staphylococcus aureus from the effluent of peritoneal cavity and exit site cultures. We began intraperitoneal cefazolin administration according to a drug susceptibility test, but the effluent cell count remained high. As we added intravenous cefazolin administration, his symptoms and cloudy effluent improved, and the effluent cell count normalized. He has not developed any recurrence of dialysate leakage or peritonitis. Our findings suggest that PD-related peritonitis accompanied by other infectious sites, such as PDPDL, should be treated with additional intravenous antibiotic therapy to taking effect on the infectious sites except for peritoneum and to keep plasma concentration of antibiotics sufficient especially in cases with preserved residual kidney function.

BACKGROUND: Since 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become prevalent worldwide. In severe cases, the case fatality rate is high, and vaccine prevention is important. This study evaluated the safety of receiving SARS-CoV-2 vaccine in patients with advanced lung cancer receiving anticancer therapy. METHODS: We prospectively enrolled patients receiving anticancer drugs for advanced lung cancer who planned to receive SARS-CoV-2 vaccination. Early adverse events within 7 days of vaccine injection were evaluated using patient-reported surveys. The chi-square test and multivariate logistic regression analyses were used. RESULTS: Among 120 patients receiving lung cancer treatment, 73 were men; the mean age of the patients was 73.5 years. The treatments received for lung cancer at the time of the first vaccine injection were chemotherapy, ICIs, combined chemotherapy and ICIs, and targeted therapies, including tyrosine kinase inhibitors, in 30, 28, 17, and 45 patients, respectively. All patients received SARS-CoV-2 messenger RNA (mRNA) vaccine. After the second mRNA vaccine dose, 15.4% of patients had fever of 38°C (95% confidence interval: 9.34%-23.2%); this rate was slightly higher than that for healthy participants at the time of the BNT162b2 trial. Patients treated with cytotoxic anticancer drugs tended to have high fever. In the multivariate analyses, male sex was associated with higher fever frequencies. However, there were no serious early adverse events due to vaccination. CONCLUSIONS: Anti-SARS-CoV-2 mRNA vaccination tends to be safe, but fever following vaccination tends to be more common among patients undergoing lung cancer treatment than among healthy individuals.

Ceftriaxone (CTRX) is known to cause reversible biliary stones/sludge, which is called biliary pseudolithiasis. We report two rare cases of biliary obstruction by pseudolithiasis shortly after completing CTRX treatment. Stones and sludge, which had not been detected before CTRX administration, appeared in the gallbladder and common bile duct and led to biliary obstruction and acute cholangitis. The obstructions were successfully treated with endoscopic retrograde biliary drainage and endoscopic sphincterotomy. CTRX-induced biliary pseudolithiasis has been reported mainly in children and adolescents but is also seen in adults with similar incidence rate. Although CTRX-induced biliary pseudolithiasis is usually asymptomatic and disappears spontaneously after discontinuing the drug, some patients develop biliary obstruction. Endoscopic managements should be considered in such cases.
