Potential mechanisms of nafamostat therapy for severe COVID-19 pneumonia with disseminated intravascular coagulation.

Nafamostat, a serine proteinase inhibitor with various actions including antithrombin, antiplasmin, and antitrypsin effects, has been used in clinical practice to treat disseminated intravascular coagulation (DIC) and pancreatitis. This case report describes the clinical course of a patient with COVID-19 pneumonia whose severe hypoxemia, probably caused by DIC and pulmonary embolism, showed remarkable improvement with combination heparin and nafamostat therapy. In addition, beneficial mechanisms of nafamostat against COVID-19 and the necessity of attention to hyperkalemia as an adverse effect are discussed.

Severe coronavirus disease 2019 (COVID-19) pneumonia patients treated successfully with a combination of lopinavir/ritonavir plus favipiravir: Case series.

The combination therapy of Lopinavir/Ritonavir plus Favipiravir might be a treatment option for patients with COVID-19. Serum ferritin levels and lymphocytopenia are promising markers for disease severity and disease progression that are commonly available in general clinical practice.

Case report: Migraine that persisted for over 20 years disappears after treatment for pulmonary arteriovenous fistula.

We presented a rare case of pulmonary arteriovenous fistula in a patient who suffered from migraine with optic aura for longer than 20 years. This case suggests that the migraine could be expected to disappear after treatment for pulmonary arteriovenous fistula.

Internal Pancreatic Fistula with Pleural Effusion Showing Elevated Levels of Amylase That Emerged 29 Years after Abdominal Surgery.

A 65-year-old woman presented to a hospital with complaints of dyspnea and lumbar pain. Chest computed tomography (CT) showed left pleural effusion. Thoracentesis showed pleural effusion with elevated levels of amylase. Enhanced CT showed fluid accumulation from the thoracic crus of the diaphragm to the left iliopsoas muscle. Based on the postoperative notes following left nephrectomy performed 29 years ago, we suspected that the internal pancreatic fistula had resulted from the postoperative scar. Conservative management was performed. However, occlusion of the pancreatic fistula failed. Subsequently, she underwent pancreatic body tail spleen merger resection, and the pleural effusion disappeared.

Real-World Evidence of Safety and Efficacy of Carboplatin plus Nanoparticle Albumin-Bound Paclitaxel in Patients with Advanced Non-Small-Cell Lung Cancer and Preexisting Interstitial Lung Disease: A Retrospective Study.

Background: Standard chemotherapy for advanced non-small-cell lung cancer (NSCLC) with preexisting interstitial lung disease (ILD) has not yet been established. Although a combination of carboplatin and paclitaxel is most frequently used for patients with advanced NSCLC and ILD, the safety and efficacy of carboplatin plus nanoparticle albumin-bound paclitaxel (nab-paclitaxel) are yet to be elucidated. Objectives: This study aimed to evaluate the safety and efficacy of carboplatin plus nab-paclitaxel for advanced NSCLC with ILD. Methods: This retrospective study included nine patients with advanced NSCLC and ILD who received carboplatin plus nab-paclitaxel as first-line chemotherapy at the National Hospital Organization Kanazawa Medical Center between April 2013 and December 2017. The ILD-GAP index was used to evaluate mortality risk of baseline ILD. Results: A usual interstitial pneumonia (UIP) pattern of ILD was observed in five (55.6%) patients on their baseline high-resolution computed tomography (HRCT) scans. The median ILD-GAP index was 4 (range, 1-5), and six (66.7%) patients had ILD-GAP index ≥4. We observed no ILD exacerbations or chemotherapy-related deaths. The overall response and disease control rates were 77.8% (95% CI, 40.0-97.2) and 88.9% (95% CI, 51.8-97.2), respectively. The median progression-free survival and overall survival were 5.8 months (95% CI, 2.1-7.7) and 8.0 months (95% CI, 2.6-16.8), respectively. Conclusions: Carboplatin plus nab-paclitaxel showed favorable safety and efficacy in patients who had advanced NSCLC and ILD with a high risk of mortality. Prospective studies are required to further confirm these results.
