Immune reconstitution inflammatory syndrome (IRIS) after starting antiretroviral treatment for human immunodeficiency virus (HIV) infection has a wide variety of causes. Delayed diagnosis and treatment of IRIS is fatal. We report a case of a 21-year-old man with HIV infection and pneumonia. The patient presented with fever and dyspnea with deterioration of pulmonary infiltrations 5 days after starting antiretroviral treatment. We reached the diagnosis of IRIS based on radial endobronchial ultrasound (EBUS)-guided lung biopsy. In conclusion, radial EBUS-guided lung biopsy via bronchoscopy is a valuable and minimally invasive technique for the rapid diagnosis of IRIS-associated pneumonia.

Introduction: Posttransplant cyclophosphamide (PTCy) has revolutionized the landscape of human leukocyte antigen (HLA)-haploidentical hematopoietic cell transplantation (haplo-HCT), providing a pivotal therapeutic option for patients with hematological malignancies who lack an HLA-matched donor.
Methods: In this retrospective analysis involving 54 adult patients undergoing PTCy-based haplo-HCT, we evaluated the impact of inhibitory killer immunoglobulin-like receptor (KIR)/HLA mismatch, alongside patient, donor, and transplant factors, on clinical outcomes within a homogeneous cohort characterized by a myeloablative conditioning regimen and bone marrow graft.
Results: With a median follow-up of 73.

Antiretroviral therapy can reduce human immunodeficiency virus (HIV) load to undetectable levels and restore CD4+ T cells to rebuild immune function in patients with HIV. However, some patients fail to achieve immune reconstitution despite treatment. Traditional Chinese medicine is an important branch of complementary and alternative medicine for the treatment of HIV infection, and a growing number of studies has demonstrated that traditional Chinese medicine can increase CD4+ T cell counts in patients, thereby promoting immune reconstitution, ameliorating symptoms and signs, and improving quality of life.

Background: Regulatory T-cells (Tregs) play a crucial role in maintaining immune homeostasis, but their dynamics are altered in a subset of people living with Human Immunodeficiency Virus (HIV) known as immunological non-responders (INRs). INRs fail to reconstitute CD4 T-cell counts despite viral suppression. This study aimed to examine Treg dysregulation in INRs, comparing them to immunological responders (IRs) and healthy controls (HCs).

Cladribine is an immune reconstitution therapy for multiple sclerosis (MS) that selectively produces long-term reductions in highly pathological memory B cells, with temporary reductions in other B- and T-cell subsets, thereby restoring immune function close to baseline levels in the short term. Here, we describe two cases of relapsing MS (RMS) treated with a second course of cladribine. Both patients were initially diagnosed with clinically isolated syndrome and later enrolled in the ORACLE-MS and CLASSIC-MS studies.

Background: Heterozygous immunoproteasome subunit beta-type 10 (PSMB10) mutations can cause severe combined immunodeficiency (SCID) and Omenn syndrome (OS). Hematopoietic stem cell transplantation in these patients is associated with severe complications and poor immune reconstitution, often resulting in death.
Objective: To perform immunological and molecular characterization of an infant with a PSMB10 heterozygous variant.
