Acquired hemophilia A (AHA) is a rare disease induced by autoantibodies to factor VIII (FVIII) and may be correlated with pregnancy, underlying malignancies, autoimmune diseases or drug administration. An 81-year-old man who presented with cough, expectoration, hemoptysis and multiple ecchymoses was diagnosed with community-acquired pneumonia by computed tomography scan. Respiratory symptoms were ameliorated after the application of antibiotics. Despite repeated infusion of fresh frozen plasma and cryoprecipitate, his prolonged activated partial thromboplastin time (APTT) maintained in the 75-110-s range and ecchymoses were not ameliorated. Then, he was transferred to the department of hematology. Based on a prolonged APTT, decreased level of FVIII and presence of antibodies against FVIII, the patient was diagnosed with AHA. Then the patient was treated with activated prothrombin complex concentrates, prednisone and intravenous immunoglobulin, resulting in a complete remission of the bleeding, recovering the FVIII level and negativity for FVIII antibody titers. Here, we investigate this novel case retrospectively and review the relevant literature.

This perspective discusses the critical role of laboratory assessments in assessing factor VIII (FVIII) inhibitors. These are auto- and alloantibodies that can develop against both endogenous and exogenous FVIII, respectively. Assessment for inhibitors represents a key part of the management of both congenital hemophilia A (CHA), an inherited deficiency, and acquired hemophilia A (AHA), an autoimmune condition.

Background: Liver transplantation is an important treatment option for liver cirrhosis in patients with HIV/HCV coinfection. In Japan, the limited number of deceased donors may force the selection of living donor liver transplantation. Appropriate graft selection is the key to success.

Introduction: We have reanalyzed the genomic data from the International Collaboration for the Genomics of HIV (ICGH), focusing on HIV-1 Elite Controllers (EC).
Methods: A genome-wide association study (GWAS) was performed, comparing 543 HIV-1 EC individuals with 3,272 uninfected controls (CTR) of European ancestry. 8 million single nucleotide polymorphisms (SNPs) and HLA class I and class II gene alleles were imputed to compare EC and CTR.

Objective: To explore the diagnosis and treatment of acquired hemophilia A (AHA) based on the analysis of clinical data.
Methods: A retrospective analysis was conducted on the clinical manifestations, laboratory characteristics, treatment, and outcomes of 25 patients diagnosed with AHA who were admitted to the Second Hospital of Hebei Medical University.
Results: Among all patients, 11 cases had secondary factors, including 5 cases of autoimmune diseases, 3 cases of pregnancy-related disease, 1 case of pemphigoid, 1 case of Graves' disease, and 1 case of monoclonal gammaglobulinemia of unknown significance (MGUS).

Objective: To analyze the various dental management strategies adopted to manage patients with hemophilia in a dental clinical setup.
Methods: An electronic database search was carried out using MEDLINE by PubMed, Scopus, Google Scholar, Web of Science, and EMBASE databases from January 2000 to August 2023 for case reports and case series published in English language. Case reports addressing the dental treatments for people with hemophilia A/hemophilia B were included.
