What is CD38 and CD138?

Abstract. Background/Aim: CD38 is a cell surface marker commonly present in plasma cells and activated T cells, while CD138 is a representative plasma cell marker.

What is a CD138 test?

CD138 is a protein present on plasma cells in the bone marrow, and on certain epithelial cells. The protein is useful to diagnose any neoplasms (tumors) growing in plasma cells. … The test, called Immunohistochemistry, involves obtaining a tissue specimen from the patient, and staining it with the CD138 stain.

What are the markers for multiple myeloma?

47·1317 The antigens CD23, CD24, CD25, CD37, CD39, CDw40, and CD45R have also been found in myeloma cells. 7 T-cell antigens (CD2 and CD4) and the neural cell adhesion mol- ecule CD56, a marker for natural killer (NK) cells, may also be present in myeloma cells.

What are CD138+ cells?

During normal B-cell development, cells acquire expression of CD138, also known as syndecan-1 (SDC1), a marker highly specific for terminally differentiated normal plasma cells (1). CD138 is a heparin sulphate proteoglycan that controls tumor cell survival, growth, adhesion and bone cell differentiation in MM (2).

What does CD138 stain?

CD138 is expressed on plasma cells and can be useful in the diagnosis of plasma cell neoplasms. Epithelial cells and endothelial cells may also express CD138. In normal tonsil tissue, CD138 strongly stains the membranes of mature plasma cells and squamous epithelial cells.

Why is immunophenotyping done?

Immunophenotyping is requested primarily to help diagnose and classify blood cell cancers (leukaemias and lymphomas). … Testing may sometimes be performed to evaluate the effectiveness of leukaemia or lymphoma treatment and to detect residual or recurrent disease, the continued presence of abnormal cells.

What is Receptiva test?

ReceptivaDx is a first of its kind test for the detection of inflammation of the uterine lining most commonly associated with endometriosis, a leading cause of infertility and implantation failure. Women testing positive for ReceptivaDx are 5 times less likely to succeed in IVF than women testing negative.

What is the difference between plasmacytoma and multiple myeloma?

Multiple myeloma is not confined to a specific bone or location within a bone. It tends to involve the entire skeleton. When only one lesion is found it is called a “plasmacytoma.” Most doctors believe that plasmacytoma is simply an early, isolated form of multiple myeloma.

What are they looking for in an endometrial biopsy?

In an endometrial biopsy, a small piece of tissue from the lining of the uterus (the endometrium) is removed and examined under a microscope for cancer and other cell irregularities. The procedure helps find the cause of a woman’s heavy or irregular bleeding.

What is usually the first symptom of multiple myeloma?

Signs and symptoms of multiple myeloma can vary and, early in the disease, there may be none. When signs and symptoms do occur, they can include: Bone pain, especially in your spine or chest. Nausea.

What does bone pain feel like in multiple myeloma?

Bone pain. Multiple myeloma can cause pain in affected bones – usually the back, ribs or hips. The pain is frequently a persistent dull ache, which may be made worse by movement.

What are the symptoms of end stage multiple myeloma?

Symptoms of Late-Stage Multiple Myeloma

  • Being sick to your stomach.
  • Bone pain in your back or ribs.
  • Bruising or bleeding easily.
  • Feeling very tired.
  • Fevers.
  • Frequent infections that are hard to treat.
  • Losing a lot of weight.
  • Not feeling like eating.

Do T cells express CD138?

Expression of CD138 has been detected on T cells from both healthy and sick mice mimicking systemic lupus erythematosus (SLE) disease. However, the characteristics and the role of CD138+ T cells in SLE pathogenesis remain largely unknown.

What is CD38 marker?

CD38 is a multi-functional transmembrane protein that is a lymphocyte receptor and a clinical marker for survival of patients with B-cell chronic lymphocytic leukemia (CLL) [1-5].

What is kappa and lambda positive cells?

The kappa/lambda ratio was defined as the ratio of the kappa-positive cell to the lambda-positive cell in plasma cells. PCM cells were distinguished from normal plasma cells by cut-off levels between 0.59 and 4.0, a sensitivity of 94.7%, and a specificity of 94.7%.

What does positive for CD138 mean?

CD138 is a classic plasma cell marker and can be found on both normal polyclonal or abnormal monoclonal plasma cells. Being CD138 positive and knowing the total plasma cell % from the core bone specimin would be the best markers to understand the extent of bone marrow infiltration.

What are plasma B cells?

Plasma cells, also called plasma B cells, are white blood cells that originate in the Lymphoid organs by B Lymphocytes and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.

What is CD10 a marker for?

CD10 is a sensitive and diagnostically useful immunohistochemical marker of normal endometrial stroma and of endometrial stromal neoplasms.

What are Immunophenotypic abnormalities?

Abnormal immunophenotype profiles are usually present in: Acute myeloid leukemia. Acute lymphoblastic leukemia (ALL)Chronic lymphocytic leukemia (CLL)B-cell and T-cell non-Hodgkin lymphomas.

What is a immunophenotyping test?

Listen to pronunciation. (IH-myoo-noh-FEE-noh-ty-ping) A process that uses antibodies to identify cells based on the types of antigens or markers on the surface of the cells. This process is used in basic research and to help diagnose diseases, such as specific types of leukemia and lymphoma.

How is a immunophenotyping test done?

Immunophenotyping is a test in which the cells in a sample of blood or bone marrow are looked at under a microscope to find out if malignant lymphocytes (cancer) began from the B lymphocytes or the T lymphocytes. The process identifies cells based on the types of antigens or markers on the surface of the cell.

How long is an era test good for?

and with proper control of endogenous progesterone (endogenous progesterone level measured within the 24 hours prior to the first intake of exogenous progesterone and <1ng/ml), the ERA® results can be applied in a personalized embryo transfer (pET) for up to 2 years following the ERA® biopsy.

Is Receptiva the same as Era?

While both tests are taken from an endometrial biopsy, the tests differ completely in their purpose. The ERA (Endometrial Receptivity Analysis) is a test that evaluates the expression of genes in an attempt to define the most optimal embryo transfer window. The ReceptivaDx test does not evaluate transfer timing.

How much does ERA testing cost?

The cost of ERA test is typically between $700 and $1,500, depending upon the location and the clinic you go to. Obviously, if you and your medical team feel that the ERA test is something that could improve your chances of success, then it is advisable to consider going ahead with this.

Hypodiploid– Myeloma cells have fewer chromosomes than normal. This occurs in about 40% of myeloma patients and is more aggressive.

Is plasmacytoma fatal?

Prognosis. Most cases of SPB progress to multiple myeloma within 2–4 years of diagnosis, but the overall median survival for SPB is 7–12 years. 30–50% of extramedullary plasmacytoma cases progress to multiple myeloma with a median time of 1.5–2.5 years.

What is the life expectancy of someone with multiple myeloma?

Multiple myeloma is a type of cancer that affects the bone marrow. Multiple myeloma is a cancer of bone marrow. Bone marrow is the spongy tissue inside the long bones. … How long can a person live with multiple myeloma?

Revised international staging system Median survival
Stage I 62 months (5 years, 2 months)

What happens if your endometrial biopsy is positive?

Biopsy results may show cell changes linked to hormone levels, or abnormal tissues, such as fibroids or polyps. These can lead to abnormal bleeding.

Why was my endometrial biopsy so painful?

It may be painful as the tube is passed through your cervix, and you may feel a cramping pain as the sample is being taken from the lining of the womb. It is exactly the same pain as a period, because the pain is caused by the same muscles of the uterus contracting.

How long does it take to get results from an endometrial biopsy?

Your doctor should have the results approximately 7 to 10 days after the biopsy. You may experience some light spotting or bleeding after the procedure, so you’ll be given a menstruation pad to wear.
