We report a case of pneumonitis with alveolar hemorrhage induced by herbal medicines in a 73-year-old woman who was admitted to our hospital because of dyspnea and an abnormal shadow on a chest radiograph. She had received treatment with numerous drugs, including the herbal medicines Seisin-renshi-in, Chotosan, Rikkunshi-to, and Shakuyakukannzo-to. Chest radiography revealed diffuse ground-glass shadows in both lungs, and bronchoalveolar lavage fluid was progressively hemorrhagic. A culture of the fluid showed no evidence of microorganisms. Moreover, there were no findings suggestive of rheumatic disease or vasculitides. On the basis of this evidence, we suspected drug-induced diffuse alveolar hemorrhage. She discontinued all medicines and started treatment with corticosteroids. Her respiratory condition and chest radiographic findings improved. The timing of administration and rechallenge with other drugs suggested that the herbal medicines were the causative drugs. The primary concern was Seisin-renshi-in, because it contains Ougon (skullcap; a known cause of pneumonitis) and because a drug lymphocyte stimulation test was positive for Seisin-renshi-in. This is the first report indicating that Seisin-renshi-in may cause diffuse alveolar hemorrhage. Diffuse alveolar hemorrhage due to herbal medicines is a rare but emergent disorder. Therefore, treating physicians should be aware that it may be caused by herbal medicines, including Seisin-renshi-in.

Objective Although chronic obstructive pulmonary disease (COPD) is characterized by systemic inflammation, the association between the neutrophil to lymphocyte ratio (NLR; an indicator of inflammation) and the clinical status of COPD has not been well studied. We hypothesized that the NLR is associated with disease severity and exacerbation in COPD patients. Methods We performed blood testing, pulmonary function testing, chest computed tomography, a body composition analysis, and a 6-minute walk test and applied the modified Medical Research Council (MMRC) dyspnea scale for 141 stable COPD patients. In addition, we calculated the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index to evaluate the disease severity. Finally, we examined the association between the NLR and clinical parameters in stable COPD patients, and we further investigated changes in the NLR between exacerbation and the stable state. Results The NLR was positively correlated with the BODE index, extent of emphysema, and MMRC score (p<0.001 for all), while inversely correlated with airflow obstruction (p<0.001), body mass index (p<0.001), fat-free mass index (p=0.001), and the 6-minute walk distance (p<0.001). We obtained the NLR during exacerbation from 49 patients. The NLR was significantly higher at exacerbation compared to the stable state (p<0.001). Conclusion The NLR was associated with disease severity and exacerbation in COPD patients. Therefore, the usefulness of the NLR in COPD patients should be elucidated in clinical settings in future investigations.
