Objective Currently, treatment of relapsed or refractory multiple myeloma is challenging. Although bortezomib-thalidomide-dexamethasone-cisplatin-doxorubicin-cyclophosphamide-etoposide (VTD-PACE), a potent combination of a proteasome inhibitor, immunomodulatory drug, and conventional chemotherapeutics, is a widely used regimen, its efficacy and safety are unclear. Methods We retrospectively analyzed the clinical data of 35 patients treated with VTD-PACE. ⋯ The response and survival durations were short in patients without SCT after VTD-PACE [median PFS: 4.0 (95% CI, 2.7-5.3) months; OS: 14.0 (6.9-21.0) months]; however, these responses significantly improved with SCT following VTD-PACE. The PFS was 8.0 (NA) months (p=0.024), and the OS was 21.0 (19.1-22.8) months (p=0.019). Conclusion VTD-PACE is an effective and tolerable salvage regimen and feasible bridging therapy for SCT.

Case Reports
An Autopsy Report of a Case with Cerebral Infarction Complicated by Coronavirus Disease 2019 Infection.
We herein report a case of cerebral infarct in a patient with coronavirus disease 2019 (COVID-19) infection who died of aspiration pneumonia. The postmortem examination of the brain revealed embolic infarct with negative findings on quantitative reverse transcription polymerase chain reaction (qRT-PCR) as well as immunohistochemistry to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The systemic examination only revealed low copy numbers of SARS-CoV-2 in the bronchus. This is the first and so far only autopsy case of COVID-19 infection with pathologic and virologic findings of the postmortem brain in Japan.

Cushing's disease causes numerous metabolic disorders, cognitive decline, and sarcopenia, leading to deterioration of the general health in older individuals. Cushing's disease can be treated with transsphenoidal surgery, but thus far, surgery has often been avoided in older patients. We herein report an older woman with Cushing's disease whose cognitive impairment and sarcopenia improved after transsphenoidal surgery. Although cognitive impairment and sarcopenia in most older patients show resistance to treatment, our case indicates that normalization of the cortisol level by transsphenoidal surgery can be effective in improving the cognitive impairment and muscle mass loss caused by Cushing's disease.

Case Reports
New-onset Seropositive Rheumatoid Arthritis Following COVID-19 Vaccination in a Patient with Seronegative Status.
Coronavirus disease 2019 (COVID-19) has spread worldwide since 2019, and mRNA vaccines for the disease have been rapidly delivered to limit the severity of infection. However, while these vaccines are effective in reducing the morbidity and severity of the disease, some patients develop severe adverse drug reactions and new-onset autoimmune phenomena, such as myocarditis, thrombosis with thrombocytopenia, and vasculitis. ⋯ We herein report a case of new-onset seropositive RA following COVID-19 mRNA vaccination. Although tests for rheumatoid factor and anti-cyclic citrullinated peptide antibody had been negative three years before vaccination, the patient developed seropositive RA following COVID-19 mRNA vaccination.

Persistent viral shedding or prolonged coronavirus disease 2019 (COVID-19) symptom is one of unresolved problem in immunocompromised individuals. We herein report an HIV/AIDS patient with Pneumocystis jirovecii pneumonia and prolonged COVID-19, possibly due to immune reconstitution inflammatory syndrome. His viral shedding and COVID-19 symptoms persisted for 39 days but were promptly resolved following sotrovimab monoclonal antibody therapy. This case suggests that prolonged COVID-19 and persistent viral shedding due to severe cellular immunodeficiency can occur in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) omicron infection and that sotrovimab is effective in the treatment of prolonged COVID-19 caused by omicron/BA.1.
