Triple-negative breast cancers (TNBC) lack expression of estrogen and progesterone receptors and overexpression or amplification of the HER2/neu oncogene, and are therefore not amenable to therapy directed at these targets. Sporadic (BRCA1 and BRCA2 germline wild-type) TNBCs share many characteristics with BRCA1 mutation-associated cancers, including a basal-like gene expression profile, frequent p53 mutations, and a high burden of genomic aberrations such as loss of heterozygosity (1-7). BRCA1 or BRCA2 (BRCA1/2)-mutated cancers have defects in several aspects of DNA repair including homologous recombination deficiency (HRD; refs. 1, 8). BRCA1/2 mutation-associated cancers have been shown to have increased sensitivity to DNA crosslinking agents such as platinum salts (9). A number of studies have suggested that some sporadic TNBC may bear substantial similarities to BRCA1/2-mutated cancers, including harboring DNA repair defects that might predispose to platinum sensitivity (1, 10, 11). ...
To study the role of the CD40-CD40 ligand interaction in the development of memory B cells and its level of action during primary antibody responses in vivo, mice were injected with a soluble CD40 fusion protein (sCD40-gamma 1), so as to block the interaction. The effects of the treatment on the primary antibody response were reminiscent of hyper-immunoglobulin M (IgM) syndrome (HIMG1): antigen-specific IgG responses were grossly inhibited whereas the IgM response was augmented severalfold. The latter observation suggests that there is a T-dependent, CD40 ligand-independent pathway of B cell activation that leads to IgM responses and that a significant component of the IgM in HIMG1 patients is derived from T-dependent responses. The secondary response was not readily blocked by sCD40-gamma 1 treatment, indicating a relative independence of CD40 ligation of antigen-experienced B cells. The most striking finding from these studies is that the development of memory B cell populations (measured by ...
Vascular compliance is a characteristic of the blood vessel wall to expand or contract with changes in pressure, and is reduced with aging or diseases like arteriosclerosis. Our goal was to investigate how hand-volume changes differ with age and to provide a simple non-invasive method to assess vascular compliance. We hypothesized that gravity-related, hand-wrist volume changes are greater in younger than in older healthy volunteers. Thirty-five healthy volunteers were classified into two age gr........

Infants with a hyper-IgM syndrome usually develop severe respiratory infections within the first year of life. Some people with a hyper-IgM syndrome may have low levels of white blood cells called neutrophils (a condition called neutropenia) and an increased risk of unusual infections, such as Pneumocystis jiroveci pneumonia or chronic diarrhea caused by infection with the parasite Cryptosporidium. People with X-linked hyper-IgM syndrome also may experience bone loss. Unusual infections and low antibody levels may indicate hyper-IgM syndrome. Normal numbers of T and B cells but elevated levels of IgM are very suggestive of this condition.. ...
Hyper-IgM Syndrome Hyper-IgM Syndrome (HIGM) is a relatively rare group of diseases resulting from mutations in the pathway from B-cell activation to isotype switching and SHM. Patients with HIGM are usually diagnosed within the first two years of life and experience severe immunosuppression, owing to decreased levels of serum IgG, IgA, and IgE (reviewed in Etzioni and Ochs 2004). Treatment options currently include intravenous supplement of immunoglobulins for which the patient is deficient as well as bone marrow transplants. Depending on the mutation causing this syndrome, different modes of inheritance are seen. The severity of phenotypes within each form of HIGM varies widely due to variability in the mutations causing the disease (Serra et al. 2001 ; Lopez-Granados et al. 2003).. Hyper-IgM Type 1 HIGM1 is an X-linked recessive disease, with the majority of cases occurring in males. Female carriers do not experience immunosuppression and undergo normal isotype switching and SHM (reviewed in ...

How is X-Linked Hyper-IGM Immunodeficiency with Ectodermal Dysplasia abbreviated? XHM-ED stands for X-Linked Hyper-IGM Immunodeficiency with Ectodermal Dysplasia. XHM-ED is defined as X-Linked Hyper-IGM Immunodeficiency with Ectodermal Dysplasia very rarely.
The X-linked hyper-immunoglobulin M syndrome (XHIGM) is an uncommon primary combined immunodeficiency disease caused by CD40L gene mutations. A delayed or missed diagnosis of XHIGM is common and concerning, owing to atypical immunoglobulin profile and phenotype of some patients, low recognition, and limited knowledge of clinicians on XHIGM in some underdeveloped areas. Opportunistic infections are a prominent clinical feature of XHIGM. However, toxoplasma encephalitis occurs sporadically and is extremely rare in patients with XHIGM.

Brief mention. The article focuses on hyper IgM syndrome . . . a heterogeneous group of disorders characterized by normal or elevated serum IgM but low serum IgG, IgA, and IgE (p. 203). The authors were interested in recent research showing that mutations in a newly described RNA editing enzyme, activation-induced cytidine deaminase (AID), can cause an autosomal recessive form of hyper IgM syndrome (p. 203). They tested a group of 27 patients with hyper IgM syndrome. They discovered three different mutations in AID among the patients, two of whom were Lumbee. They chose to test the two Lumbee patients because the Lumbee are known to have an increased incidence of hyper IgM syndrome (p. 204).. ...

Different genetic defects cause HIgM syndrome, the vast majority are inherited as an X-linked recessive genetic trait and most sufferers are male.[7]. IgM is the form of antibody that all B cells produce initially, before they undergo class switching due to exposure to a recognized antigen. Healthy B cells efficiently switch to other types of antibodies as needed to attack invading bacteria, viruses, and other pathogens. In people with hyper IgM syndromes, the B cells keep making IgM antibodies because they cant switch to a different antibody. This results in an overproduction of IgM antibodies and an underproduction of IgA, IgG, and IgE.[11][7]. ...

Hyper IgM (HIGM) syndromes are a group of rare genetic disorders leading to ineffective immune responses. People with this immune defect are usually diagnosed in early childhood due to frequent infections.
Many diseases have a genetic origin and are passed on in families. Most primary immunodeficiency diseases are inherited in one of three different ways: X-linked recessive, autosomal recessive or autosomal dominant. Family history and laboratory studies can be helpful in establishing the possible role of genes or chromosomes in a particular primary immunodeficiency disease and

It is estimated that about 5-10% of tumors have a familial background. Familial or hereditary cancer is the consequence of germinal alterations (mutations) in specific genes that increase the susceptibility to develop a malignant tumor. There are however still many variants of which the pathogenicity is unknown. In addition, many families are unaware that they have an inherited predisposition to cancer. A key example of this is in primary immunodeficiency disease (PID) families. ...

Depression is the most common mental health disorder among HIV-patients. Recognizing and treating depression is important in order to improve quality of life and health outcomes in those living with HIV. In clinical practice selective serotonin reuptake inhibitors (SSRIs) are used most frequently in HIV patients with depressive symptoms. A complicating factor in the concomitant use of antiretroviral agents and antidepressant therapy is the occurrence of drug-drug interactions. Citalopram can be seen as one of the preferred SSRIs in HIV-infected patients because citalopram has a relatively favourable drug interaction profile compared to other SSRIs. Raltegravir is an HIV-1 integrase inhibitor and is frequently being used as antiretroviral agent in combination with tenofovir/emtricitabine in HIV-patients. Raltegravir has shown sustained antiretroviral activity, is generally well tolerated and has little propensity to interact with other drugs because it does not inhibit or induce CYP450 enzymes. ...

Primary immunodeficiency diseases (PIDDs) are genetically determined disorders of the immune system resulting in greatly enhanced susceptibility to infectious disease, autoimmunity and malignancy. As most subjects with PIDDs present with infections, the differential diagnosis and initial investigations for an underlying immune defect are typically guided by the clinical presentation. In subjects with PIDDs, individual infections are not necessarily more severe than those that occur in a normal host. Rather, the clinical features suggestive of an immune defect may be the recurring and/or chronic nature of infections with common pathogens that may result in end organ damage, such as bronchiectasis. Several immune globulin products have already been approved by the FDA ...

3M syndrome is a disorder that causes short stature (dwarfism), unusual facial features, and skeletal abnormalities. The name of this condition comes from the initials of three researchers who first identified it: Miller, McKusick, and Malvaux. It is caused by mutations in the CUL7 gene and is inherited in an autosomal recessive pattern ...
Because primary immunodeficiency diseases (PI) are so rare, many doctors are unfamiliar with how to diagnose and treat them. This is why a PI diagnosis can take some time. Doctors often try ruling out other problems first, and as such, the average amount of time from the onset of symptoms to diagnosis is between 9 and 15 years, based on survey data from the Immune Deficiency Foundation (IDF). Unlike people with more common conditions, an individual with PI may be the only person with PI who the ...

PY - 1999. Y1 - 1999. N2 - We report a case of an 11-year-old boy who underwent successful bone marrow transplantation for X-linked hyper-IgM syndrome (XHIM). The donor was an HLA-matched brother. The patient was conditioned with busulfan, cyclophosphamide and anti-thymocyte globulin. He received 4.7 x 108 marrow cells per kg from the donor. Prophylaxis against graft-versus-host disease consisted of cyclosporine and short-term methotrexate. The clinical course after the bone marrow transplantation was uneventful, and 12 months after transplantation the patient was doing well with no need for therapy. We examined expression of the CD40 ligand (CD40L) on the patients activated T lymphocytes and in vitro production of immunoglobulins by his lymphocytes. Although expression of CD40L was totally absent ...
