Interest in the procedure increased in the 1990s due to the development of more effective methods for harvesting granulocytes and a growing population of people with severe neutropenia from chemotherapy. However, the treatment's efficacy remains poorly understood and its use is controversial. [2] [3] [4]
Neutropenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood. [4] Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood. [5]
A QSP model of neutrophil production and a PK/PD model of a cytotoxic chemotherapeutic drug (Zalypsis) have been developed to optimize the use of G-CSF in chemotherapy regimens with the aim to prevent mild-neutropenia. [13] G-CSF was first trialled as a therapy for neutropenia induced by chemotherapy in 1988.
Either empirical antiviral or antifungal therapy or both should be considered. In addition to infections due to neutropenia, a patient with the Acute Radiation Syndrome will also be at risk for viral, fungal and parasitic infections. If these types of infection are suspected, cultures should be performed and appropriate medication started if ...
Neutropenia generally develops in the second week. During this period, many clinicians recommend pegfilgrastim or prophylactic use of ciprofloxacin . [1] If a fever develops in the neutropenic period, urgent medical assessment is required for neutropenic sepsis , as infections in patients with low neutrophil counts may progress rapidly.
Isatuximab, sold under the brand name Sarclisa, is a monoclonal antibody (mAb) medication for the treatment of multiple myeloma. [6] [4]The most common side effects include neutropenia (low levels of neutrophils, a type of white blood cell), infusion reactions, pneumonia (infection of the lungs), upper respiratory tract infection (such as nose and throat infections), diarrhoea and bronchitis ...
Neutropenia indicates a deficiency of neutrophils (the most common granulocyte cell) only. [citation needed] To be precise, neutropenia is the term normally used to describe absolute neutrophil counts (ANCs) of less than 500 cells per microlitre, whereas agranulocytosis is reserved for cases with ANCs of less than 100 cells per microlitre.
Neutropenia, a subtype of leukopenia, refers to a decrease in the number of circulating neutrophil granulocytes, the most abundant white blood cells. The terms leukopenia and neutropenia may occasionally be used interchangeably, as the neutrophil count is the most important indicator of infection risk. Agranulocytosis is an acute form of ...
