The therapeutic administration of subcutaneous immunoglobulin (SCIg) offers various advantages over intravenous immunoglobulin (IVIg). This narrative review examines and compares SCIg versus IVIg in chronic inflammatory demyelinating polyneuropathy (CIDP). SCIg is as effective as IVIg but is better tolerated and easier to administer, as intravenous access is not required. Furthermore, SCIg administration is more convenient and cost-effective than IVIg, enabling flexible treatment scheduling at home and improving patients' overall quality of life. The availability of highly concentrated immunoglobulin G (IgG) subcutaneous solutions, such as IgPro20, a 20% IgG solution stabilized with L-proline, allows for the administration of larger volumes in a single session, while the parallel development of new technological devices enables the delivery of higher doses over a shorter time. Based on the results of the PATH study, SCIg has become a well-established therapy in CIDP. In addition to discussing the advantages of SCIg, this review summarizes the evolution of SCIg by discussing all the relevant clinical studies which have considered its use in the treatment of CIDP.

Background: Due to its strong immunogenicity and tumor specificity, neoplastic antigen has emerged as an immunotherapy target with wide therapeutic prospect and clinical application value. Anti-programmed death-1 (PD-1) antibodies reinvigorate T cell-mediated antitumor immunity. So, we conducted single-arm trial to assess the safety and efficacy of PD-1 blockade(Camrelizumab)-activated neoantigen specific cellular therapy (aNASCT) on advanced relapsed non-small lung cancer(NSCLC)(ClinicalTrials.

Objective To prepare mouse anti-human lymphocyte activation gene 3 (LAG3) monoclonal antibody (mAb) and perform immunological identification of the antibody. Methods BALB/c mice were immunized with LAG3-mLumin-3T3 cells, which stably express the extracellular and transmembrane regions of human LAG3 in mouse 3T3 cells. The secretion of anti-human LAG3 antibodies in mouse serum was assessed using flow cytometry and immunofluorescence.

From the Division of Allergy and Immunology, Department of Medicine, University of California San Diego, La Jolla, California and.

Idiopathic non-mast cell angioedema (INMA) is a rare disease typified by recurrent attacks of cutaneous and subcutaneous swelling. Every attack carries the potential for severe morbidity and, in the case of laryngeal involvement, mortality. Whereas therapies approved for hereditary angioedema (HAE) have been used in the care of patients with INMA, little is known with regard to their efficacy for the treatment of this disease.

Nephrotic syndrome (NS) and atopic diseases are linked through shared immunological pathways, with allergic triggers often contributing to NS relapses, particularly in immunoglobulin E (IgE)-mediated pathways. Omalizumab, a humanized monoclonal antibody targeting free and cell-bound IgE, is commonly used in treating atopic diseases. We presented a pediatric case with a history of eczema, asthma, and recurrent atopic rhinitis, who first developed NS at age three, responding well to steroid therapy.

In acetylcholine receptor (AChR) antibody-positive generalized myasthenia gravis (gMG), neonatal Fc-receptor (FcRn) inhibition has broadened the therapeutic spectrum. Myasthenic crisis (MC), heralded by an impending myasthenic crisis (iMC), is a critical condition requiring treatments with rapid onset and sustained efficacy. Currently treatments used for iMC, including intravenous immunoglobulins and plasma exchange/immunoadsorption, have limitations, such as delayed onset of action and potential side effects.
