So although the problem presents as an inability of B cells to make an appropriate antibody response to infections, the defect is on T cells. [dermnetnz.org]

The age at presentation was 1-18 months and showed variable clinical severity. They presented with respiratory infection of viral origin followed by bacterial infections. [jpgmonline.com]

However, two patients with EDA-ID presented with hyper IgM syndrome (67). [lvts.fr]

The fungus is common and is present in over 70% of healthy people’s lungs, however, Hyper IgM patients are not able to fight it off without the administration of Bactrim[medical citation needed]) Hepatitis (Hepatitis C) Chronic diarrhea Hypothyroidism [en.wikipedia.org]

• Recurrent Respiratory Infections

  The most common problem in all forms of HIGM syndrome is an increased susceptibility to infection including recurrent upper and lower respiratory tract infections. [primaryimmune.org]

Clinical Testing and Workup Blood tests will be ordered to determine the status of immunoglobulins in the blood, including normal or high levels of IgM and low levels of other immunoglobulin classes. [rarediseases.org]

[edit] In terms of treatment for hyper IgM syndrome, there is the use of allogeneic hematopoietic cell transplantation. [en.wikipedia.org]

Diagnosis The diagnosis of hyper IgM syndrome can be done via the following methods and tests: MRI Chest radiography Pulmonary function test Lymph node test Laboratory test (to measure CD40) Treatment In terms of treatment for hyper IgM syndrome, there [owlapps.net]

Because of the poor prognosis, the treatment of choice is a human leukocyte antigen (HLA)-identical sibling bone marrow transplant at an early age (62,63). Treatment for this condition also includes monthly IVIG infusions (64). [lvts.fr]

While a permanent cure is anticipated after successful stem cell transplantation, the long-term prognosis for these patients is not yet known. [primaryimmune.org]

Given her compromised lung condition, with a potential poor prognosis, she was immediately started on regular intravenous Ig therapy, which obviated further study of in vivo antibody responses, such as the responses to previously administered vaccines [cvi.asm.org]

Therapy and Prognosis Five patients had died (Table 1). P5 developed SSPE after measles virus infection at 15 years old and died within one year. P14 was infected by mycobacterium tuberculosis and died of tuberculous meningitis at 10 years old. [hindawi.com]

Epidemiology Frequency United States In 2003, the US XHIGM registry reported that the minimal incidence rate of XHIGM was approximately 1 in 1,000,000 live births from 1984-1993. [4] This may be an underestimation because not all physicians in the United [emedicine.medscape.com]

Pathophysiology CD40 is a costimulatory receptor on B cells that, when bound to CD40 ligand (CD40L), sends a signal to the B-cell receptor. When there is a defect in CD40, this leads to defective T-cell interaction with B cells. [owlapps.net]

This results in an overproduction of IgM antibodies and an underproduction of IgA, IgG, and IgE.[13][7] Pathophysiology[edit] CD40 is a costimulatory receptor on B cells that, when bound to CD40 ligand (CD40L), sends a signal to the B-cell receptor.[14 [en.wikipedia.org]

Children receiving this treatment get regular infusions of donated blood plasma to prevent infections. In boys with XHIM, IVIG replaces missing IgG antibodies while normalizing levels of IgM. [childrens.com]

However it may not prevent the opportunistic infections. In some cases it also improves growth. Trimethoprim + sulphamethoxazole may be given prophylactically to prevent Pneumocystis jirovecii infection. [dermnetnz.org]

Platelets are specialized blood cells that help prevent and stop bleeding. [rarediseases.org]

Mutations in the CD40LG gene lead to the production of an abnormal CD40 ligand or prevent production of this protein. If CD40 ligand does not attach to its receptor on B cells, these cells cannot produce IgG, IgA, or IgE antibodies. [medlineplus.gov]
