Bioavailability is just the percentage of medication that enters the circulation. A low bioavailability does not necessarily mean the medication will be ineffective.

Chemotherapy-induced neutropenia, a symptom of neutrophil depletion, makes cancer patients highly susceptible to invasive fungal infection with substantial morbidity and mortality.

Effects of high (10 μg) and low (1 μg) levels of LTA and antibiotics on PMN lifespan (a) and survival (b) in human neutrophils isolated from healthy volunteers (n = 5). Effects on PMN lifespan and survival were determined at 16 h following stimulation using flow cytometry with Annexin V and propidium iodide (PI).

Even with adequate early empiric antibiotic treatment, bacteremia due to GNRs in the setting of neutropenia is associated with crude mortality rates as high as 34% to 50%.[7,10] Therefore, antibacterial prophylaxis for neutropenic patients has been proposed in an effort to reduce febrile neutropenia, infection (particularly with gram-negative pathogens), and mortality in high-risk populations.

Additional causes. Conditions present at birth, such as Kostmann's syndrome (a disorder involving low production of neutrophils) Unknown reasons, called chronic idiopathic neutropenia.

Surprisingly, although low serum levels of soluble Fc-γ receptor and high levels of granulocyte colony-stimulating factor (G-CSF) have been recognized as risk factors for developing infection in patients with SLE and neutropenia, absolute neutrophil count, bone marrow findings, measurements of the marrow neutrophil reserve and serum levels of neutrophil granule components have not .

Hospitalization and immediate empiric antibiotic therapy results in safe, satisfactory resolution of the episode of fever and neutropenia in more than 95% of cases. 1 However, not all cases of fever and neutropenia are clinically equivalent. 2, 3 Some patients appear quite well in hospital, whereas others have extremely complicated courses.

These subsets are believed to execute different functional roles based on the severity and stages of infection. For example, in human volunteers challenged with LPS (2 ng/kg i.v.), a population of CD16 low ROS low neutrophils that has a reduced capacity to generate oxidative burst is detected in blood at 3 h after challenge .

Neutropenia is a condition where there are abnormally low levels of neutrophils in the blood supply. Neutrophils are an important type of white blood cell, vital for fighting off pathogens ...

Patients with neutropenic fever are usually admitted to the hospital for cultures and broad-spectrum I.V. antibiotic therapy. Patho­gens causing infections in cancer patients are usually endogenous flora colonizing the skin and the respiratory, genitourinary, and GI tracts.
