Hypergammaglobulinemia is a medical condition with elevated levels of gamma globulin. It is a type of immunoproliferative disorder. Types
Hypergammaglobulinemia is a condition that is characterized by the increased levels of a certain immunoglobulin in the blood serum. The name of the disorder refers to an excess of proteins after serum protein electrophoresis (found in the gammaglobulin region).Most hypergammaglobulinemias are caused by an excess of immunoglobulin M (IgM), because this is the default immunoglobulin type prior to class switching. Some types of hypergammaglobulinemia are actually caused by a deficiency in the other major types of immunoglobulins, which are IgA, IgE and IgG. There are 5 types of hypergammaglobulinemias associated with hyper IgM.MeSH considers hyper IgM syndrome to be a form of dysgammaglobulinemia, not a form of hypergammaglobulinemia. Type 1
X-linked immunodeficiency with hyper–immunoglobulin M, which is also called type 1 hyper IgM, is a rare form of primary immunodeficiency disease caused by a mutation in the Tumor Necrosis Factor Super Family member 5 (TNFSF5) gene, which codes for CD40 ligand. This gene is located on the long arm of the X chromosome at position 26, denoted Xq26. Normally, CD40 ligand is expressed on activated T cells, and is necessary to induce immunoglobulin class switching from IgM to the other immunoglobulin types. It does this by binding to its ligand, CD40, which is found expressed on the surface of B cells.
It is difficult to distinguish if the prevention was a result of the probiotic supplementation or if it was a result of the properties of human milk. It is also still unclear if probiotic administration reduces LOS risk in extremely low birth weight infants due to the limited number of studies that investigated it. Out of the 37 studies included in this systematic review, none indicated any safety problems related to the probiotics. It would be beneficial to clarify the relationship between probiotic supplementation and human milk for future studies in order to prevent late onset sepsis in neonates.In a randomized controlled trial of 3,003 very low birth weight (VLBW) infants, Heart Rate Characteristics (HRC) monitoring reduced all-cause mortality by 22%, mortality after infection by 40%, reduced length of stay in the NICU after controlling for improved survival, and reduced mortality as well as mortality-or-severe-cerebral-palsy at 18–22 months corrected age among the extremely low birth weight (ELBW) patients.

From 1993 to 2007, doctors at Kaiser Permanente Medical Care Program hospitals, Brigham Womens Hospital, and Beth Israel-Deaconess Medical Center conducted a nested case-control study in an effort to create a better quantitative method for determining risk factors for neonatal early-onset sepsis. The study examined over 600,000 live births of infants born less than or equal to 34 weeks gestation.
