Multiple myeloma (MM) is a malignant plasma cell disease that currently cannot be cured. Several new drugs have continuously been introduced in the recent years. New drugs targeting B-cell maturation antigen (BCMA) have greatly improved the efficacy and prognosis of MM compared with traditional treatments.

Introduction: Pomalidomide is used for treating multiple myeloma in patients who have relapsed after prior treatment with lenalidomide and a proteasome inhibitor. Common side effects include mild cytopenias, and deep vein thrombosis. While papulo-erythematous rash has been described, hair effects are rare with this class of agents.

Article Synopsis
  • Multiple myeloma (MM) initially manifesting in the sphenoid sinus and skull base is rare, with a systematic review of 34 cases highlighting the challenges of early diagnosis and treatment, particularly for the IgD-λ subtype.
  • A unique case of IgD-λ MM showed symptoms like dizziness and blindness, leading to a confirmed diagnosis and a wide range of diagnostic tests, including advanced imaging and biopsies.
  • The study emphasizes the importance of using CT and MRI scans for detecting bone damage, and suggests that endoscopic procedures are effective for tissue biopsies, which can improve diagnosis in asymptomatic regions like the paranasal sinuses.

Lambda light chain - restricted non - crystalline proximal tubulopathy with cast nephropathy in multiple myeloma: a case report and literature review.

BMC Nephrol

September 2024

Departments of Pathology, Xijing Hospital, School of Basic Medicine, Fourth Military Medical University, 169 Changle Western Street, Xi'an, 710032, Shaanxi, China.

Background: Multiple myeloma (MM) often causes renal tubular damage, such as the light chain cast nephropathy (LCCN) and the light chain proximal tubulopathy (LCPT). The excessive light chains deposited in the proximal and distal tubules usually manifest with different characteristics, leading to a rare coexistence of the two pathological conditions. Here we report a unique case of a patient with multiple myeloma (MM) who presented with acute kidney injury (AKI) due to dual conditions of λ light chain-restricted non-crystalline LCPT and LCCN.

Immunoglobulin class-switch recombination: Mechanism, regulation, and related diseases.

MedComm (2020)

August 2024

Department of Pathogen Biology School of Basic Medicine, Tongji Medical College and State Key Laboratory for Diagnosis and Treatment of Severe Zoonotic Infectious Diseases, Huazhong University of Science and Technology Wuhan Hubei China.

Maturation of the secondary antibody repertoire requires class-switch recombination (CSR), which switches IgM to other immunoglobulins (Igs), and somatic hypermutation, which promotes the production of high-affinity antibodies. Following immune response or infection within the body, activation of T cell-dependent and T cell-independent antigens triggers the activation of activation-induced cytidine deaminase, initiating the CSR process. CSR has the capacity to modify the functional properties of antibodies, thereby contributing to the adaptive immune response in the organism.
