Does Daratumumab cause neutropenia?
Grade 3-4 neutropenia is a common adverse event in patients on daratumumab, Lonial noted. This happens most often when the drug is combined with another agent, such as pomalidomide, rather than when given as a single agent.
Does dexamethasone cause neutropenia?
Univariate logistic regression analysis revealed that dexamethasone is a risk factor for severe neutropenia (OR 17.0; 95%CI: 1.3–223.1).
What lab value is considered neutropenic?
A healthy person has an ANC between 2,500 and 6,000. The ANC is found by multiplying the WBC count by the percent of neutrophils in the blood. For instance, if the WBC count is 8,000 and 50% of the WBCs are neutrophils, the ANC is 4,000 (8,000 × 0.50 = 4,000). When the ANC drops below 1,000 it is called neutropenia .
Does daratumumab cause immunosuppression?
“Daratumumab promotes T-cell expansion and activation, depletes immunosuppressive regulatory cells, and has multiple different mechanisms of action.” However, daratumumab is not the only immunomodulatory agent under investigation in multiple myeloma.
Does Velcade cause neutropenia?
Lowered white blood cells (neutropenia). VELCADE can cause low levels of neutrophils which are a type of white blood cell that help to fight infections. If your white blood cells become low, you can be at higher risk for infections. Tell your doctor if you develop a fever or believe you have an infection.
Which drugs can cause neutropenia?
There are many medications that can result in drug-induced neutropenia. The most common are carbimazole, clozapine, dapsone, dipyrone, methimazole, penicillin G, procainamide, propylthiouracil, rituximab, sulfasalazine, and ticlopidine.
Does dexamethasone affect neutrophils?
Summary: Glucocorticoids (e.g., dexamethasone, methylprednisolone, prednisone) are known to increase the white blood cell (WBC) count upon their initiation. The increase in WBC count is primarily contributed from neutrophils (polymorphonuclear leukocytes; PMN).
Is 2.2 a low neutrophil count?
A normal neutrophil count (also called absolute neutrophil count or ANC) is between 2,500 and 6,000. A low neutrophil count (less than 1,000) is known as neutropenia. The lower the neutrophil count, the higher the risk of infection.
Does DARZALEX suppress the immune system?
The monoclonal antibody Darzalex works by attaching to the CD38 protein on the multiple myeloma cell. By doing this, Darzalex directly kills or helps your immune system destroy the multiple myeloma cell. How the drug works is also called its mechanism of action.
What are the side effects of daratumumab?

- chest pain or tightness.
- facial swelling.
- headache.
- puffiness or swelling of the eyelids or around the eyes, lips, or tongue.
- rapid, shallow breathing.
- skin rash, hives, or itching.
- slow or fast heartbeat.
Are neutrophils low in multiple myeloma?
High-density neutrophils in MGUS and multiple myeloma are dysfunctional and immune-suppressive due to increased STAT3 downstream signaling. A.
Does bortezomib cause immunosuppression?
Proteasome inhibition by bortezomib has both immunosuppressive and immunostimulatory effects.
Do steroids lower neutrophils?
Corticosteroids also inhibit the ability of neutrophils to adhere to vessel walls, which is an essential step in the migration of cells from the circulation into the tissue. The net effect is a reduced number of neutrophils available to accumulate at the inflammatory site.
Does dexamethasone cause neutrophilia?
Dexamethasone-induced neutrophilia was similar to that induced by other corticosteroids. Dexamethasone in a dose of 6 mg/m2 produced minimal discomfort while inducing an adequate neutrophilia in the volunteers.
