RESUMEN
A 72-year-old woman was admitted to our hospital with numbness in her lower extremities and hypereosinophilia. She was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). On admission, she was suspected of being complicated with pneumonia and sepsis; therefore, treatment with mepolizumab monotherapy was begun, resulting in partial improvement. After the possibility of a complicating infection was ruled out, corticosteroids were initiated, followed by intravenous gamma globulin therapy. Although the induction of remission of EGPA with mepolizumab monotherapy is not usually recommended, induction with mepolizumab monotherapy may be an option in terms of safety and clinical efficacy in some cases.

A 38-year-old woman had a history of asthma for 20 years. Bullous lesions had appeared on her left side of the back. Two months before admission, the biopsy revealed eosinophilic cellulitis. One month later, she experienced numbness in both legs. She was admitted to our hospital for emergency treatment due to chest pain and loss of consciousness. Emergency coronary angiography revealed triple-vessel vasospasm. She had cardiac arrest for 4 min during the examination. We suspected eosinophilic granulomatosis with polyangiitis due to pulmonary infiltrate, eosinophilia, and a history of illness. We, therefore, started methylprednisolone pulse therapy. Although her condition and laboratory findings improved, cardiac magnetic resonance (CMR) imaging performed on day 16 showed myocardial oedema and myocardial fibrosis on late gadolinium enhancement. Coronary angiography on day 35 revealed no spasm, and myocardial biopsy showed the absence of vasculitis. There was no improvement in myocardial oedema. CMR showed enlargement of late gadolinium enhancement and formation of a ventricular aneurysm. As myocarditis did not improve sufficiently, five courses of intravenous cyclophosphamide pulse therapy were administered. CMR on day 152 showed the disappearance of myocardial oedema. We report a unique case of successful treatment of severe myocarditis and the usefulness of follow-up CMR.

Recently, the use of immune checkpoint inhibitors (ICIs) with or without chemotherapeutic agents has been increasing in the treatment for advanced cancer. Here, we report the occurrence of liver failure after the use of pembrolizumab in an 82-year-old woman with metastatic liver disease derived from right advanced renal pelvis, ureteral cancer, and bladder cancer. She was successfully treated with 0.6 mg/kg daily prednisolone. In patients treated with ICIs, ICI-induced hepatitis is occasionally observed. Even if patients are older, it appears important to diagnose and treat ICI-induced hepatitis earlier by multidisciplinary therapies including steroid treatment. This is a first report of pembrolizumab-induced liver failure in elder patient with age over 80 years. Even if patients are older, it appears important to diagnose and treat ICI-induced hepatitis earlier by multidisciplinary therapies including steroid treatment.
RESUMEN
A 26-year-old woman presented with abdominal pain, diarrhoea, vomiting, fever, and progressive paralysis in the lower limbs. She had a history of bronchial asthma and experienced sinusitis, progressive peripheral neuropathy, polyarthritis, and leukocytosis with prominent eosinophilia. The patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). Abdominal pain was considered to be an ischaemic enteritis associated with EGPA. She was administered 1,000 mg/day of methylprednisolone for 3 days and intravenous immunoglobulin (400 mg/kg/day of γ-globulin for 5 days) followed by 50 mg (1 mg/kg)/day of oral prednisolone due to rapidly progressing peripheral neuropathy. Her symptoms temporarily improved; however, peripheral neuropathy recurred after a week, and the eosinophil count increased. Eighteen days after following the resumed treatment, 300 mg of mepolizumab, a humanised monoclonal antibody, was administered. Subjective symptoms, nerve conduction velocity, and skin perfusion pressure (an index of peripheral circulation in the lower extremities) improved after 4 weeks. Although mepolizumab has been approved for EGPA, there is no evidence of its efficacy against peripheral neuropathy. Early introduction of mepolizumab may contribute to an the early improved progressive peripheral neuropathy with eosinophilia.
