Six weeks after the second cycle, he developed interstitial pneumonia and was administered prednisolone (50 mg/day). However, thrombocytopenia did not improve. Bone marrow biopsy showed scarce megakaryocytes ( less then 1 megakaryocyte/10 high-power fields) with preservation of myeloid and erythroid series. Myelodysplasia, myelofibrosis, or metastatic lesions were not observed. Cytogenetic analysis showed a normal male karyotype of 46XY. Hence, the patient received eltrombopag, a thrombopoietin receptor agonist, and his platelet count subsequently improved. After recovery, bone marrow aspiration revealed a normal number of megakaryocytes. AATP is rarely the type of thrombocytopenia induced by ICIs and may be successfully treated with thrombopoietin receptor agonists.Tumor flare reaction (TFR) is a unique immune-mediated tumor recognition phenomenon presenting as rapid enlargement of the tumor, which mimics disease progression, developing in the early stage of treatment using immunomodulatory drugs or immune checkpoint inhibitors. A 59-year-old man with follicular lymphoma had residual tumor burden in the left hilar lymph nodes after R-CHOP therapy, and received lenalidomide and rituximab (R2) therapy. He developed respiratory distress on day 11 of R2 therapy. Chest X-ray and CT demonstrated left lung atelectasis due to left hilar lymph node swelling. We performed transbronchial lung biopsy on day 20 of R2 therapy. The biopsied left bronchus tissue exhibited extensive necrosis, which had a B-cell phenotype consistent with that of follicular lymphoma. Neither NK cells nor cytotoxic T cells were detected. It was unclear whether the immune effector cells disappeared at the time of transbronchial lung biopsy. Atelectasis in our patient improved by continuing R2 therapy beyond TFR.The prevalence of cancer-associated anemia (CIA) is high, and the mechanisms governing its development remain poorly understood. Eryptosis, the suicidal cell death of red blood cells (RBCs), may account for CIA as it is triggered by clinically approved chemotherapeutics including cisplatin and paclitaxel. Physcion (PSN), an anthraquinone extracted from rhubarb and other plants, has shown great promise as an anticancer agent. However, the potential toxicity of PSN to RBCs remains elusive. RBCs were isolated from heparinized blood, and incubated with 10-100 µM of PSN for 24 h at 37 °C. Hemolysis was photometrically calculated from hemoglobin concentration in the medium at 405 nm, while flow cytometry was employed to investigate cardinal markers of eryptosis. Phosphatidylserine (PS) exposure was detected by Annexin-V-fluorescein isothiocyanate (FITC), intracellular calcium by Fluo4/AM, cellular volume from forward scatter (FSC), and oxidative stress by 2',7'-dichlorodihydrofluorescein diacetate (H2DCFDA). PSN induced overt hemolysis at 50 and 100 µM which was not mediated through calcium influx, protein kinase C, casein kinase 1α, or receptor-interacting protein 1. Moreover, PSN caused significant increase in Annexin-V-FITC and Fluo4 fluorescence with no appreciable influence on FSC or DCF values. Accordingly, PSN stimulates premature eryptosis characterized by PS externalization and intracellular calcium overload without cell shrinkage or oxidative damage. In conclusion, this report shows, for the first time, that PSN is cytotoxic to RBCs by inducing hemolysis and programmed cell death which may limit its success as a chemotherapeutic agent.We herein report a 31-year-old man with recurrent aseptic meningitis associated with Kikuchi's disease. Although aseptic meningitis is the most common neurological complication of Kikuchi's disease, its characteristics remain unclear, especially in recurrent cases. A literature review revealed that aseptic meningitis associated with Kikuchi's disease was more likely to occur in men and was associated with a low cerebrospinal fluid (CSF)/serum glucose ratio. Lymphadenopathy tended to occur simultaneously or after the onset of meningitis. When encountering a patient with aseptic meningitis of unknown etiology, it may be worthwhile to focus on the CSF/serum glucose ratio and lymphadenopathy with a careful examination.A 47-year-old Japanese man was referred to our hospital because of a sustained high fever with diarrhea 12 days after a flight from India. Liver enzymes were elevated with rose spots, hepatosplenomegaly, relative bradycardia, and acute cholecystitis. A liver biopsy depicted the dense infiltration of lymphocytes and Kupffer cells in sinusoids and the granulomatous formation in the parenchyma. The liver damage was initially resolved with the administration of ceftriaxone for 16 days but flared up 1 week later. Laboratory tests yielded positive reactions for Salmonella typhi and hepatitis E virus RNA. The pathophysiological presentations of concurrent typhoid and type E hepatitis are discussed.Objective Painless thyroiditis (PT) is characterized by transient hyperthyroidism with a low 99mTc uptake. We herein describe 11 cases of PT that occurred during treatment with potassium iodide (KI) for Graves' disease (GD). Methods From August 2016 to December 2018, 11 women with GD who developed PT during treatment with KI were enrolled. Of these patients, 10 discontinued antithyroid drug (ATD) because of side effects and began KI, and 1 patient switched from thiamazole to KI because she was planning a pregnancy. The mean patient age was 40.1 years old. Thyroid function tests, thyroid autoantibodies including anti thyroglobulin antibody (TgAb), anti-thyroperoxidase antibody (TPOAb), and M22-TRAb, and the 99mTc uptake were evaluated at the time of PT. Results All 11 women patients presented with transient thyrotoxicosis in which 99mTc scans revealed a low uptake of 0.34±0.15% (normal 0.70-1.02%). M22-TRAb was absent in all cases except for one (2.4 IU/L), whereas TgAb and TPOAb were present in 10 and 6 cases, respectively. Ten patients returned to a euthyroid status without passing through the post-hypothyroid phase, and one patient underwent total thyroidectomy during the euthyroid phase of PT. Only four patients require beta-blocker therapy. All patients with KI-induced PT except 1 displayed GD remission during a mean observation period of 23.3 months, and 1 patient had recurrence of GD after PT. Muramyl dipeptide solubility dmso Conclusion We encountered 11 GD patients who developed PT during treatment with KI, which was initiated after ATD had been discontinued due to side effects.
