Neutropenia is defined as a condition of abnormally low number of neutrophils, as a result of granulocyte disorder of that leads to Immunodeficiency with lower than normal circulating white blood cells. Patients with neutropenia are susceptible to bacterial infections causes of neutropenic sepsis.
Neutropenia is either
problems in the production of the cells by the bone marrow and
destruction of the cells from somewhere else in the body, if neutrophil
count falls below 1,000 cells per microliter of blood.
Neutropenia can be classified into acute and chronic types, depending to the duration of the illness. Some researchers divided severity of the disease, depending to the absolute neutrophil count (ANC) and is described as follows(a).
1. Mild neutropenia, when the ANC falls below a lower limit of 1500 per mm3 (1.5 x 109 /1), but remains higher than 1000 per mm3 (1.0 x 109 /1).
2. Moderate neutropenia, when the ANC falls between 500 per mm3 and 1000 per mm3 (0.5 x 109 /1 - 1.0 x 109 /1)
3. Severe neutropenia, when the ANC falls below 500 per mm3 (0.5 x 109 /1)
Treatments
In traditional Chinese medicine perspective
1. Herbal extract granules
In the study applied the highest standard of clinical trial methodology
to
examine the role of CHM in reducing chemotherapy-induced toxicity, while
maintaining a tailored approach to therapy with one hundred and twenty
patients were accrued at the time of premature study termination.
Enrolled patients were randomly assigned to one of three Chinese
herbalists who evaluated and prescribed a combination of single-item
packaged herbal extract granules. Patients received either CHM or
placebo packages with a corresponding serial number. The placebo package
contained nontherapeutic herbs with an artificial smell and taste
similar to a typical herbal tea. The primary end points were hematologic
and non-hematologic toxicity according to the National Cancer Institute
Common Toxicity Criteria Version found that patient characteristics of
the two groups were similar. The incidence of grade 3/4 anemia,
leukopenia, neutropenia,
and thrombocytopenia for the CHM and placebo groups were 5.4%, 47.3%,
52.7%, and 1.8% and 1.8%, 32.2%, 44.7%, and 3.6%, respectively (P =
0.27, 0.37, 0.63, and 0.13, respectively). Incidence of grade 2 nausea
was the only non-hematologic toxicity that was significantly reduced in
the CHM group (14.6% versus 35.7%, P = 0.04)(69).
2. Lycium barbarum polysaccharide (LBP)
In the study to nvestigate the therapeutic effects of Lycium barbarum
polysaccharide (LBP) on mitomycin C (MMC)-induced myelosuppressive mice,
found that LBP at 100 mg/kg (LBP-L) on day 14 and LBP at 200 mg/kg
(LBP-H) on days
10, 14, 17, 19 and 21, significantly ameliorated the decrease of
peripheral RBC, HGB and hematocrit (HCT) of myelosuppressive mice
compared to the control. LBP-L on days 12 and days 14 and LBP-H on days
10, 12, 14, 17, 19 and 21, significantly enhanced peripheral PLT
recovery of myelosuppressive mice compared to the control. LBP-H on days
12, 17, 19 and 21, significantly inhibited the increase of mean
platelet volume (MPV) of myelosuppressive mice compared to the control.
LBP showed no obviously effect on neutropenia induced in mice by MMC(70).
3. Fu Zheng and the Gong Xiao
In the study of observed the effect of chemotherapy combined with Chinese herbs
and western drugs on white blood cell count in 31 patients with gastric
cancer with patients were divided into 3 groups: (1) Fu Zheng
(strengthen the body
resistance) with invigorating the Spleen and Kidney recipe; (2) Fu Zheng
with western drugs raising WBC and enhancing immunity; (3) Gong Xiao
(eliminating the evil factors and mass) with promoting blood circulation
to remove blood stasis recipe or eliminating the evil factors and mass
recipe, suggested that invigorating the Spleen and Kidney recipe had
specific
effect on decreasing the toxicity and side effect of chemotherapy,
preventing bone marrow
suppression and leukopenia, and was better than western drugs used in
group II. It showed in the treatment of cancer with TCM, we must pay
attention to the relationship between the Fu Zheng and the Gong Xiao(71).
3. Chinese herbal medicine
In the study to evaluate traditional Chinese medicine
(TCM) in improving quality of life (QOL), reducing chemotoxicity and
modulating immune function in patients undergoing chemotherapy, found
that there was no significant difference in the GHS between the two
groups.
With adjustment for stage, chemotherapy type, disease status, age and
baseline value, emotional function, cognitive function and nausea and
vomiting were found to be worse or less improved in the TCM group
compared with placebo group after six cycles of chemotherapy. The TCM
group had less neutropenia after three cycles (0% grade 4 neutropenia
versus 28.6%). There were no other significant differences in terms of
chemotoxicity. Lymphocyte counts and cytokine activities decreased less
in the TCM group(72).
Other inthe searching of The Cochrane Breast Cancer Specialised
Register (15/02/2007), The
Cochrane Central Register of Controlled Trials (CENTRAL); (The Cochrane
Library 2006, Issue 4); MEDLINE (1966 to December 2006); EMBASE (1990 to
December 2006); and Chinese Biomedical Literature (2006, Issue 4),
indicated that the searching provides limited evidence about the
effectiveness and safety of Chinese medicinal herbs in alleviating chemotherapy induced short term side effects. Chinese medicinal herbs,
when used together with chemotherapy, may offer some benefit to breast
cancer patients in terms of bone marrow improvement and quality of life,
but the evidence is too limited to make any confident conclusions(73).
