Abstract
Background The increasing number of patients with miliary tuberculosis (MTB) is a concern in an aging society because of its high mortality rate. Several prognostic biomarkers for MTB have been identified; however, the predictive ability of monocytes as biomarkers remains unknown. This study demonstrates the usefulness of monocytes as prognostic biomarkers for MTB. Materials and methods We retrospectively compared the clinical findings of 52 patients with MTB hospitalized between April 2013 and October 2021. The predictive ability of biomarkers for 3-month prognosis and their cutoff values were calculated. Survival times and longitudinal changes in monocytes after initiating treatment were compared. Results A smaller number of monocytes (#M), higher lymphocyte-monocyte ratio (LMR), higher neutrophil-monocyte ratio, and poorer performance status were associated with death within 3 months. #M was an independent prognostic factor. #M and LMR exhibited the highest predictive performance compared to others using receiver operating characteristic curve analysis (area under the curve = 0.86 and 0.85, respectively). Survival time was shorter in patients with #M ≤ 200 cells/μL and LMR > 2.5. Rapidly increasing #M after treatment was related to better prognosis in patients with #M ≤ 200 cells/μL at diagnosis. Conclusions #M at diagnosis and longitudinal changes in monocytes are related to MTB prognosis.

Abstract
Cholinergic urticaria (CholU) is classified into several subtypes: (1) conventional sweat allergy-type CholU (conventional SAT-CholU), (2) CholU with palpebral angioedema (CholU-PA), 3) CholU with acquired anhidrosis and/or hypohidrosis (CholU-Anhd); 1) and 2) include SAT based on pathogenesis. There have been no studies on differences in the prevalence of bronchial asthma among the subtypes. We analyzed bronchial responsiveness using the methacholine dose indicator Dmin, respiratory symptoms, and exhaled nitric oxide (FeNO). Median log10 Dmin (interquartile range) of patients with conventional SAT-CholU (n = 11), CholU-PA (n = 11), and CholU-Anhd (n = 11) was 0.381 (- 0.829, 1.079), 0.717 (0.249, 0.787), and 1.318 (0.121, 1.699), respectively (p = 0.516). Respiratory symptoms were less frequently observed in CholU-Anhd than in conventional SAT-CholU or CholU-PA. FeNO of patients with conventional SAT-CholU, CholU-PA, and CholU-Anhd was 23 (18.5, 65.0), 39 (32.0, 59.5), and 25 (19.0, 33.0) ppb, respectively (p = 0.237). Nine% of conventional SAT-CholU patients and more than half of CholU-PA patients required treatment for asthma. Log Dmin tended to be lower in patients with SAT-CholU than in those with CholU-Anhd. CholU-PA might be associated with asthma.

Abstract
Objective Bronchial thermoplasty (BT) is a bronchoscopic procedure for patients with severe asthma. Although it has been suggested that BT works by reducing airway smooth muscle, the detailed mechanism underlying its effects is still unknown. Methods We performed xenon ventilation computed tomography (Xe-CT) before each BT procedure and six weeks after the third treatment to assess the improvement in lung ventilation at each separate lung region. The air trapping index in each lobe was defined as the mean trapping value (0: none, 1: mild, 2: moderate, and 3: severe) of the included segments. Patients and Materials Four patients were included. Results Asthma symptoms were improved after BT. The comparison of the scores at baseline with those after the third treatment showed that the air trapping index was improved in both the treated and untreated regions. However, neither the pulmonary function nor the exhaled nitric oxide was improved. Conclusion Using Xe-CT, we successfully evaluated the air trapping in patients who underwent BT. The improvement in asthma symptoms by BT may be related to the amelioration of peripheral lung ventilation in both the treated and untreated regions.

Abstract
BACKGROUND Lettuce-associated respiratory allergy has never been reported before. The aim of this study was to clarify the clinical condition of lettuce-associated respiratory allergy and to identify the lettuce antigen which induces allergic symptoms. METHODS We distributed questionnaires to 1168 lettuce farmers and performed medical examinations in those who exhibited respiratory symptoms related to occupational exposure to lettuce. We analysed specific IgE-binding proteins in the sera of patients through immunoblotting analysis and determined molecular characterization of the IgE-binding bands using liquid chromatography-mass spectrometry. RESULTS A total of 932 farmers (80%) responded to the questionnaire. Of those, 7% exhibited lettuce-associated respiratory symptoms, during harvesting and packaging. Thirteen patients were diagnosed with allergy to lettuce and agreed to undergo further examinations. The percentage of activated basophils in these patients was significantly higher compared with that reported in negative controls (P < .05). Lettuce-specific IgE (ImmunoCAP® ) and skin prick testing was positive in 46% and 62% of patients, respectively. Notably, occupational lettuce-allergic asthma was detected in one patient through specific bronchial provocation testing. The IgE-binding bands recognized in the sera of >50% of patients were identified as epidermis-specific secreted glycoprotein EP1-like (51 kDa). CONCLUSION The present analysis identified a novel lettuce allergen. This allergen may have clinically useful applications, such as specific IgE testing and allergen-specific immunotherapy.

Abstract
Purpose Adjuvant chemotherapy with cisplatin (CDDP) plus vinorelbine is the standard regimen for the treatment of non-small cell lung cancer (NSCLC). However, CDDP elicits severe toxic effects, including emesis, neurotoxicity, and renal damage; carboplatin (CBDCA) may be a feasible alternative for CDDP-unfit patients. CBDCA plus paclitaxel (PTX) adjuvant chemotherapy showed a survival benefit for patients with stage IB tumors >4 cm in size, while CBDCA plus nanoparticle albumin-bound (nab)-PTX showed greater efficacy and lower neurotoxicity than CBDCA plus PTX in advanced NSCLC. Here, we investigated the feasibility of using CBDCA plus nab-PTX as adjuvant chemotherapy for NSCLC. Patients and Methods Patients with completely resected stage II or III NSCLC, with an Eastern Cooperative Oncology Group performance status of 0–1 and adequate kidney function, received four cycles of postoperative adjuvant chemotherapy with CBDCA (AUC=5 mg/mL/min, on day 1) and nab-PTX (100 mg/m2, on days 1, 8, and 15) administered every 4 weeks within 8 weeks after surgery. The study was designed as a prospective, single-center, Phase II study. The primary endpoint was the completion rate of chemotherapy; secondary endpoints were two-year relapse-free survival (RFS) and safety. The expected completion rate was 80%, with a 50% lower limit. Results Of 21 enrolled patients, 18 (85.7%) were CDDP-unfit owing to age (≥75 years old [n=11, 52.4%]) or mild renal impairment (n=7, 33.3%). Nineteen of the 21 enrolled patients were assigned to the intervention. The most common grade 3 or 4 adverse events were neutropenia (n=15, 78.9%) and anemia (n=3, 15.8%). The completion rate for the four cycles was 63.2% (95% CI, 38.4–83.7). Two-year RFS was 56.8% (95% CI, 29.7–76.9). Conclusion The completion rate for CBDCA plus nab-PTX as adjuvant chemotherapy for CDDP-unfit NSCLC patients did not reach treatment feasibility. Further dose modifications may be required in future studies.

Abstract
Hypertrophic pulmonary osteoarthropathy (HPO) is a paraneoplastic syndrome characterized by digital clubbing, arthritis, and periostitis. Tumor removal usually leads to the resolution of these symptoms. We herein report the efficacy of crizotinib treatment for treating the symptoms of HPO associated with c-ros oncogene 1 receptor tyrosine kinase (ROS1)-rearranged lung cancer. A 71-year-old woman presented with a pulmonary tumor and arthritis. She was diagnosed with a ROS1-rearranged lung adenocarcinoma [stage IIIB (cT4N2M0) ] with HPO. Crizotinib dramatically reduced the tumor size and resolved the symptoms. After two months of crizotinib treatment, she underwent lobectomy, and a pathological evaluation revealed ypstage IIIA (ypT3a, ypN1). Crizotinib treatment was effective for reducing the tumor size and improving the symptoms of HPO.

Abstract
Transformation to small cell lung cancer is one phenomenon of acquired resistance to anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors in ALK rearrangement-positive non-small cell lung cancer (NSCLC). Few case reports have focused on other types of histological transformation. We report a case of transformation of ALK rearrangement-positive adenocarcinoma to NSCLC with neuroendocrine differentiation during alectinib therapy. A 36-year-old woman presented with a tumor in the left lower lobe and bone metastases. She was diagnosed with ALK rearrangement-positive adenocarcinoma by histopathology of the primary tumor. Alectinib had been effective for 8 months before new lesions appeared. Histopathological re-examination of a recurrent tumor revealed poorly differentiated carcinoma with insulinoma-associated protein 1 (INSM1) expression, which remained ALK-positive. Expression of CD133, BCL-2, and SOX2 was positive in comparison to the initial tumor. Expression of SOX2 became more strongly positive than it was before treatment. The immunohistochemical findings of these markers associated with cancer stem-like cells and/or neuroendocrine differentiation suggest that cancer stem cells play a role in the mechanisms of histological transformation and acquired resistance of ALK rearrangement-positive cancer. To our knowledge, this is the first report to suggest an association between cancer stem-like cells and histological transformation in ALK rearrangement-positive lung cancer.

Abstract
Background Sphingosine kinase phosphorylates sphingosine to generate sphingosine 1 phosphate (S1P) following stimulation of the five plasma membrane G-protein-coupled receptors. The objective of this study is to clarify the role of S1P and its receptors (S1PRs), especially S1PR3 in airway epithelial cells. Methods The effects of S1P on asthma-related genes expression were examined with the human bronchial epithelial cells BEAS-2B and Calu-3 using a transcriptome analysis and siRNA of S1PRs. To clarify the role of CCL20 in the airway inflammation, BALB/c mice were immunized with ovalbumin (OVA) and subsequently challenged with an OVA-containing aerosol to induce asthma with or without intraperitoneal administration of anti-CCL20. Finally, the anti-inflammatory effect of VPC 23019, S1PR1/3 antagonist, in the OVA-induced asthma was examined. Results S1P induced the expression of some asthma-related genes, such as ADRB2, PTGER4, and CCL20, in the bronchial epithelial cells. The knock-down of SIPR3 suppressed the expression of S1P-inducing CCL20. Anti-CCL20 antibody significantly attenuated the eosinophil numbers in the bronchoalveolar lavage fluid (P<0.01). Upon OVA challenge, VPC23019 exhibited substantially attenuated eosinophilic inflammation. Conclusions S1P/S1PR3 pathways have a role in release of proinflammatory cytokines from bronchial epithelial cells. Our results suggest that S1P/S1PR3 may be a possible candidate for the treatment of bronchial asthma.

Abstract
Hypoparathyroidism with sensorineural deafness and renal dysplasia (HDR) syndrome is an autosomal dominant condition caused by mutations of the gene encoding the dual zinc-finger transcription factor, GATA3. A previous study identified some patients with GATA3 gene variants and breast cancer, suggesting that GATA3 variants may contribute to tumorigenesis in estrogen receptor 1-positive breast tumors; however, these patients did not have HDR syndrome. A 32-year-old nonsmoking Japanese woman was histologically diagnosed with lung squamous cell carcinoma associated with HDR syndrome and a c.C952T>C (p.C318R) germline mutation in GATA3. This is the first report describing cancer in a patient with HDR syndrome. Our data indicates that GATA3 mutations may be a potential therapeutic target for lung cancer.

Abstract
A 62-year-old male with lung adenocarcinoma harboring an exon 19 deletion in the Epidermal growth factor receptor (EGFR) was treated with EGFR-tyrosine kinase inhibitors (TKIs) and several cytotoxic agents. After administering a fifth-line chemotherapy regimen, a liver biopsy revealed a diagnosis of recurrence with a T790M mutation. After an 82-day course of osimertinib therapy, the patient developed osimertinib-induced interstitial lung disease (ILD). Osimertinib was discontinued, and oral prednisolone was started. The ILD quickly improved, but liver metastases progressed and osimertinib was restarted concurrently with prednisolone. The patient showed neither disease progression nor a recurrence of ILD at 5 months. In situations in which no alternative treatment is available, osimertinib rechallenge should thus be considered as an alternative treatment.

Abstract
A 20-year-old Japanese woman with a history of pulmonary atresia was referred to our hospital after the detection of an abnormal mass in the right lung and mediastinal lymphadenopathy. A cytological specimen obtained by transbronchial brushing indicated that the pathological diagnosis was non-small cell lung cancer. During the follow-up period, the tumor spontaneously regressed. At four months after the diagnosis, she experienced sudden bleeding from the small intestine. The histological characteristics of the small intestine tumor were compatible with the cytological characteristics of the lung tumor. Detailed immunohistochemical analyses led to a final diagnosis of epithelial angiosarcoma of the small intestine, which might have formed metastatic lesions in the lung.

Abstract
Background Sphingosine-1-phosphate (S1P) is a bioactive phospholipid that acts as a signal transducer by binding to S1P receptors (S1PR) 1 to 5. The S1P/S1PRs pathway has been associated with remodeling and allergic inflammation in asthma, but the expression pattern of S1PR and its effects on non-immune cells have not been completely clarified. The aim of this study was to examine the contribution of the signaling of S1P and S1PRs expressed in airway epithelial cells (ECs) to asthma responses in mice. Methods Bronchial asthma was experimentally induced in BALB/c mice by ovalbumin (OVA) sensitization followed by an OVA inhalation challenge. The effects of S1PR antagonists on the development of asthma were analyzed 24 h after the OVA challenge. Results Immunohistological analysis revealed S1PR1-3 expression on mouse airway ECs. Quantitative real-time polymerase chain reaction demonstrated that S1P greatly stimulated the induction of CCL3 and TIMP2 mRNA in human airway ECs, i.e., BEAS-2B cells, in a dose-dependent manner. Pretreatment with the S1PR2 antagonist JTE013 inhibited the CCL3 gene expression in BEAS-2B cells. Immunohistological analysis also showed that the expression level of CCL3 was attenuated by JTE013 in asthmatic mice. Furthermore, JTE013 as well as anti-CCL3 antibody attenuated allergic responses. Intratracheal administration of JTE013 also attenuated eosinophilic reactions in bronchoalveolar lavage fluids. S1P induced transcription factor NFκB activation, while JTE013 greatly reduced the NFκB activation. Conclusions JTE013 attenuated allergic airway reactions by regulating CCL3 production from bronchial ECs. The intratracheal administration of JTE013 may be a promising therapeutic strategy for bronchial asthma.

Abstract
We evaluated the usefulness of oximetry tests that are frequently used as screening tools for sleep apnea syndrome (SAS) by determining the level of agreement between oximetry test results and polysomnography test (PSG) results. We retrospectively examined 135 patients suspected of having SAS. Although the oximetry desaturation index (DSI) seemed better than the oximetry apnea index in the agreement with the polysomnography respiratory disturbance index (RDI), the criteria of DSI greater than or equal to 15 was not sensitive enough to screen for moderate SAS (PSG-RDI >or= 20). Multivariate analyses revealing that body mass index (BMI) as well as DSI correlated well with PSG-RDI, we established a new criterion by adding the BMI score (DSI >or= 15 or BMI >or= 25), which remarkably improved the sensitivity. This criterion may be useful not only in clinical practice but also in medical checkups for asymptomatic patients, and also suggests that obese patients with sleep disturbance should undergo PSGs, irrespective of the DSI score.
