Serum immunoglobulins and complement factors were investigated retrospectively in 35 splenectomised (n = 28) and autoreplanted (n = 7) patients following trauma. The main deficiency of the immune system following splenectomy was a reduction in the concentrations of serum IgM, C3, and Factor B with normal IgG, IgA and C4 values. These changes were not correlated with the time elapsed after splenectomy. However, patients who had splenic tissue autoreplantation had normal values of immunoglobulins and complement factors compared with healthy controls. Splenic replantation may be able to stop a fall in immunoglobulin and complement factor values after splenectomy.

Department of Hematology, Peking Union Medical College Hospital, Chinese Academy of Medical Science and Peking Union Medical College, Beijing, People's Republic of China.
Objective: To evaluate the short-term efficacy and safety of eculizumab for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in China.
Method: Data were retrospectively collected from patients with PNH who received at least 3 months of full-dose eculizumab. Changes in clinical and laboratory indicators after 1, 3, and 6 months of eculizumab therapy and at the end of follow-up were documented.
Complement-Mediated Hemolytic Uremic Syndrome Due to MCP/CD46 Mutation: A Case Report.

Thrombotic microangiopathy (TMA) is a severe condition characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage, often involving the kidneys. Complement-mediated hemolytic uremic syndrome (cHUS), a rare form of TMA, arises from dysregulated alternative complement pathway activation, frequently due to genetic mutations. We report the case of a 23-year-old male presenting with TMA secondary to a heterozygous mutation in the membrane cofactor protein (MCP/CD46) gene.

C3 glomerulopathy (C3G), a rare kidney disease caused by dysregulation of alternative pathway complement activation, is characterized by glomerular C3 deposition, proteinuria, crescentic glomerulonephritis, and renal failure. The anti-C5 monoclonal antibody (mAb) drug eculizumab has shown therapeutic effects in some but not all patients with C3G, and no approved therapy is currently available. Here, we developed and used a triple transgenic mouse model of fast progressing lethal C3G (FHm/mP-/-hFDKI/KI) to compare the therapeutic efficacy of a bifunctional anti-C5 mAb fused to a functional factor H (FH) fragment (short consensus repeat 1-5 [SCR1-5]) and the anti-C5 mAb itself.

Streptococcus mutans, the principal pathogen associated with dental caries, impacts individuals across all age groups and geographic regions. Beyond its role in compromising oral health, a growing body of research has established a link between S. mutans and various systemic diseases, including immunoglobulin A nephropathy (IgAN), nonalcoholic steatohepatitis (NASH), infective endocarditis (IE), ulcerative colitis (UC), cerebral hemorrhage, and tumors.

The human leukocyte antigen (HLA) system plays a critical role in transplant immunology, influencing outcomes through various immune-mediated rejection mechanisms. Hyperacute rejection is driven by preformed donor-specific antibodies (DSAs) targeting HLAs, leading to complement activation and graft loss within hours to days. Acute rejection typically occurs within six months post-transplantation, involving cellular and humoral responses, including the formation of de novo DSAs.
