Factors Associated with Neutralizing Antibody Responses following 2-Dose and 3rd Booster Monovalent COVID-19 Vaccination in Japanese People Living with HIV.

People living with HIV (PLWH) could be at risk of blunted immune responses to COVID-19 vaccination. We investigated factors associated with neutralizing antibody (NAb) responses against SARS-CoV-2 and variants of concern (VOCs), following two-dose and third booster monovalent COVID-19 mRNA vaccination in Japanese PLWH. NAb titers were assessed in polyclonal IgG fractions by lentiviral-based pseudovirus assays.

Serum immunoglobulin G as a discriminator of infection in follicular lymphoma patients undergoing chemotherapy with bendamustine in combination with rituximab.

Objectives: Chemotherapy, including bendamustine, usually causes lymphocytopaenia and hypogammaglobulinaemia as side effects in patients with haematological malignancies. Therefore, the possibility has been considered that these immunological adverse events induced by bendamustine may lead to infectious diseases. However, lymphocytopaenia and/or hypogammaglobulinaemia have not yet been shown to have a statistically significant association with infection in cancer patients who receive bendamustine.

Efficacy and Safety of the Modified EPOCH Regimen (Etoposide, Vincristine, Doxorubicin, Carboplatin, and Prednisolone) for Adult T-cell Leukemia/Lymphoma: A Multicenter Retrospective Study.

Background: We retrospectively analyzed patients with untreated aggressive adult T-cell leukemia/lymphoma who received the modified EPOCH (mEPOCH) regimen.

Patients And Methods: Patients received up to 6 mEPOCH cycles. Etoposide (50 mg/m/day), doxorubicin (10 mg/m/day), and vincristine (0.

[The Usefulness of the Scan with 67Ga-citrate to Assess the Therapeutic Effect on Pneumocystis pneumonia with HIV-1 Infection].

Objective: Peumocystis pneumonia (PCP) is one of the common opportunistic infections with severe respiratory failure, and is sometimes life-threatening in patients with the acquired immunodeficiency syndrome. Although treatment for PCP is established, an appropriate treatment period has not been evaluated to clarify the risk factors for immune reconstitution inflammatory syndrome (IRIS) associated with PCP.

Method: We retrospectively analyzed the clinical characteristics of risk factor, which are the treatment period for PCP, and 67Ga scintigraphy (Ga-S) at the 21st day from the start of the treatment for PCP, with 21 cases of PCP and HIV infection treated during 2005-2012 at Kyushu Medical Center.

[CMV-induced duodenal papillitis in a patient with HIV-1 infection].

We present herein a case report of a 59-year-old patient with HIV-1 infection who developed a CMV-induced pseudotumor of the duodenum. The patient presented with oral pain and dysphagia. Physical examination revealed oral thrush.

[Transfusion-related acute lung injury during the treatment of EBV-associated hemophagocytic lymphohistiocytosis].

Transfusion-related acute lung injury (TRALI) is a severe pulmonary complication following blood transfusions. We experienced a case of possible TRALI during the course of EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH). A 19-year-old woman was admitted to our hospital suffering from fever and abdominal pain.
