Cold agglutinin disease is a subtype of autoimmune hemolytic anemia that occurs via the activation of specific anti-red blood cell antibodies (agglutinins) at low temperatures. Autoimmune hemolytic anemia has been reported to cause interstitial pneumonia; however, the underlying mechanism remains unclear. ⋯ Treatment with prednisolone improved the course of cold agglutinin disease and organizing pneumonia in a similar manner. To our knowledge, this is the first report of cold agglutinin associated with organizing pneumonia, suggesting a potential link between the two.

Vanishing bile duct syndrome (VBDS) is characterized by bile duct degeneration and necrosis, which result in bile duct loss and bile stasis. A 70-year-old man had malaise after receiving celecoxib. Laboratory tests revealed elevated hepatobiliary enzymes. ⋯ However, his condition continued to deteriorate, and he died. An autopsy showed that liver regeneration was poor, and bile duct loss was exacerbated. The pathological autopsy findings were consistent with VBDS.

Objective Many vascular endothelial growth factor (VEGF) pathway inhibitors are used in the treatment of patients with various advanced cancers; however, treatments induce cardiovascular adverse events (CVAEs), such as hypertension, heart failure, arrhythmia, arterial or venous embolism, and hemorrhage. Some studies have suggested a correlation between efficacy and CVAEs; however, further evidence is required. This study evaluated real-world data concerning the frequency and degree of CVAEs and possible associations between CVAEs and efficacy in such patients. ⋯ Furthermore, the PFS of patients with a CVAE grade ≥3 in the early period was favorable compared to that of those with CVAEs of grades 0-2. Taken together, a higher degree of CVAE was correlated with favorable patient outcomes. Conclusion This study revealed the frequency and degree of CVAEs in patients with solid cancers who received VEGF pathway inhibitors in a real-world setting and added evidence regarding the correlation between CVAEs and efficacy of VEGF pathway inhibitors.

A 53-year-old man with chronic dyspnea and bilateral pleural effusion was subsequently diagnosed with idiopathic chylothorax. Lymphatic scintigraphy confirmed lymphatic fluid leakage at the left venous angle, prompting management with lymphaticovenular anastomosis (LVA). ⋯ Approximately three years and three months after the presentation, the patient succumbed to CO2 narcosis and renal failure. It is crucial to study additional cases in order to uncover new causes and develop pathology-based treatments for this condition.
