Egg white intake during chemotherapy is common advice for cancer patients for the prevention of leukopenia. However, the benefit is uncertain. We conducted this prospective study to identify the relationship of egg white intake for gynecologic cancer patients who received carboplatin and paclitaxel and the occurrence of leukopenia. Between January 2014 and January, 2015, 81 patients were interviewed regarding their intake of egg whites before receiving subsequent chemotherapy. The basic data, the details of egg white intake and the grade of leukopenia in the previous cycle were recorded. The mean age was 54.1 years and 80% of the patients had a diagnosis of ovarian or endometrial cancer. The patients were interviewed at cycles 1-3 in 45 cases, 4-6 in 45 cases and 7-9 in two cases. Subsequent dose reduction was found in 6.2% and granulocyte-stimulating growth factors was given at 4.9%. All the patients ate egg whites with variations in the number of eggs per day as follows: less than one (3), one to two (56), three to four (14) and five to six (8). Over 70% were recommended by nurses to eat egg whites and about 63% of patients received other supplemental food. Some 44.1% of the patients who ate less than or equal to two eggs per day and 36.4% who ate more than two eggs per day developed grade 2-4 leukopenia, P = 0.61. In conclusion, the data did not provide evidence in support of the conclusion that a greater egg white intake could significantly reduce the occurrence of leukopenia.

연구배경 : 결핵치료중 단독 백혈구감소증은 비교척 드물게 발생하지만 치료면에서 임상적으로 중요한 의미를 가진다. 불필요하게 약제를 변경하면 치료기간이 길어지고, 이로 인하여 치료에 대한 순응도가 낮아지고 완치율이 감소할 수 있기 때문이다. 그러나 항결핵요법 중에 발생하는 백혈구감소증에 대한 적절한 치료지침이 없는 실정이다. 따라서 저자들은 결핵치료 중 발생한 경 중등중 백혈구감소증의 추이를 관찰하고, 같은 약제를 계속 사용할 수 있는지를 알아보기 위하여 본 연구를 수행하였다. 방 법 : 1997년 1월부터 1999년 8월사이에 단기 항결핵요법을 시행한 환자중에서 치료중 경 중둥증의 단독 백혈구감소증이 발생하였으나 지속적으로 같은 약제를 투여한 36명의 환자중, 추적검사에서 탈락된 1명을 제외한 35명(25명은 전향적, 10명은 후향적 방법)을 대상으로 하였다. 백혈구감소증을 유발할 수 있는 다른 조건이 있는 환자는 연구대상에서 제외하였다. '경 중동증의 단독 백혈구감소증'은 백혈구 수가 $2,000-3,499/mm^3$ 사이이고, 다른 혈액학적 이상이 없는 경우로 임의로 정의하였다. 전향적 연구는 치료 중 경 중등증의 백혈구감소증이 발생하였을 때 같은 약제를 지속적으로 사용하면서 CBC를 3-7일 간격으로 검사하였고, 빽혈구수가 $2,000/mm^3$ 미만으로 감소하거나 감염성 합병증이 발생하는 경우에는 약제를 변경하기로 하였다. 결 과 : 1) 35명 모두 같은 약제로 지속적으로 치료하면서 백혈구수가 $2,000/mm^3$미만으로 감소하거나 다른 합병증없이 치료를 종료하였다. 2) 치료 시작부터 백혈구 감소증이 처음 발견될 시점까지 기간은 평균 $64{\pm}65$일이었다. 3) 치료 전 평균 백혈구수는 $5,021{\pm}1,605/mm^3$, 최저치는 $2,911{\pm}395/mm^3$ 이었으며 치료종료 후 회복되었다($4,248{\pm}1,270/mm^3$, p<0.05). 4) 백혈구감소의 주된 원인은 중성구의 감소이었다($3,319{\pm}1,747$ vs. $1,485{\pm}396/mm^3$, p<0.05). 결 론 : 1차약제 단기 항결핵치료 중 경 중둥증($2,000-3,499/mm^3$)의 단독 백혈구감소증이 발생하였을 때, 치료약제 변경없이 백혈구수를 추적검사하면서 지속적으로 같은 약제를 사용하여도 무사히 치료를 종료할 수 있을 것으로 사료되었다.

Purpose: The major side effects of treatment with oxcarbazepine (OXC) are skin rash and hyponatremia. Hematologic side effects are reported rarely. The aim of this study was to investigate the rate and types of the hematologic side effects of OXC. Methods: The medical records of 184 patients diagnosed with epilepsy or movement disorder and on OXC monotherapy, at the Department of Pediatrics of Inje University Sanggye Paik Hospital from July 2001 to July 2018, were retrospectively reviewed. Results: Of the 184 patients, 10 (5.4%) developed leukopenia in addition to pancytopenia and 2 (1.0%) developed pancytopenia. Leukopenia developed in 11 days to 14 years after OXC administration and was more frequent in males than in females (male vs. female, 9 vs. 1; Fisher exact test, P<0.05). Of the eight patients with leukopenia alone, 7 continued OXC treatment; 6 improved without intervention; 1 was lost to follow-up; and 1 received a reduced OXC dose, who improved after intervention. Pancytopenia developed within 2 months of initiation of OXC treatment. Both patients initially continued OXC. One improved within 1 month and continued treatment with OXC, but the other showed progression of the side effect, leading to the discontinuation of OXC and subsequent improvement within 1 month. There were no significant differences in the ages of the patients, OXC dose, and duration of OXC treatment between patients with and without these side effects of OXC (P>0.05, t-test). Conclusion: OXC-induced leukopenia is not rare and may result in pancytopenia. Patients being treated with OXC should be regularly monitored for abnormal complete blood count profiles.

Homozygous mutations in NUDT15 R139C are known as the major factor associated with thiopurine-induced early leukopenia, particularly in Asian patients. Therefore, NUDT15 genotyping is currently recommended before thiopurine treatment to identify patients who are NUDT15 poor metabolizers and consider the use of an alternative immunomodulatory therapy. We report a case of a 12-year-old Korean girl with Crohn's disease (CD), in whom thiopurine-induced leukopenia was prevented by initiation of azathioprine (AZA) therapy at a low dose (0.5 mg/kg/day) and early detection of significant hair loss and white blood cell (WBC) count decrease at 17 days from the start of AZA treatment. The WBC count dropped from 8,970/μL to 3,370/μL in 2 weeks, and AZA treatment was stopped because of concerns of potential leukopenia in the near future. Her WBC count recovered to 5,120/μL after 3 weeks. Gene analysis later revealed that she had a homozygous mutation in NUDT15 R139C, resulting in a poor metabolizing activity of NUDT15. In situations when NUDT15 genotyping is unavailable, initiation of AZA therapy at 0.5 mg/kg/day with close observation of hair loss and WBC counts within 2 weeks may be an alternative way to prevent thiopurine-induced early leukopenia in Asian children with CD.

Objectives: We performed a systematic review and meta-analysis to explore the recent clinical research trends regarding the effects of traditional herbal medicine (THM) on chemotherapy-induced leukopenia. Methods: Randomized controlled trials that verified effects of herbal medicine treating chemotherapy induced leukopenia were included in the study. A literature search was performed in the English, Chinese, and Korean databases for papers published from January 1, 2007, to September 1, 2017. The selected literature was assessed by Cochrane's Risk of Bias (RoB). Results: Forty-two of 232 randomized controlled trials met the inclusion criteria. The most commonly used herbal prescriptions called '升白湯 (shengbai decoction)' which means elevating the numbers of White blood cells (WBCs). And the mostly included herbs such as Astragali Radix, Angelicae Gigantis Radix, Atractylodis Rhizoma Alba, Codonopsis Pilosulae, Glycyrrhizae Radix, Ligustri Lucidi Fructus are commonly used to elevate qi, blood and yin. The count of WBC in peripheral blood, the level of leukopenia presented in WHO (World Health Organization), and clinical symptoms were used to evaluate the treatments. The effective rate was 68.6-98.18% and the effectiveness was significantly higher in the intervention group than in the control group in 38 articles (p<0.05). No serious adverse events were reported. Only five articles (5/42, 11.9%) were rated as having adequate methodological quality with a low level of bias. Conclusion: Some traditional herbal medicines may be effective as therapeutic treatments for chemotherapy-induced leukopenia, but the majority of reviewed studies were of poor quality. The present findings need to be confirmed by rigorously conducted high-quality trials, including pharmacokinetic studies, to confirm the absence of interactions between traditional herbal medicine agents and chemotherapy.

Leukopenia is a commonly encountered adverse event experienced by cancer patients. It can cause serious infections and delays in chemotherapy. We describe a case of leukopenia induced by colon cancer chemotherapy. After acupuncture treatment, the patient showed improvement in the leukopenia and completed the scheduled chemotherapy without delay or additional administration of granulocyte colony-stimulating factor (G-CSF). Therefore, acupuncture may have a substantial benefit for treatment of leukopenia in this patient.

Purpose: To assess chemoradiation related acute morbidity in women with carcinoma cervix and to find and correlation between hematologic toxicity and organ system specific damage. Materials and Methods: A prospective study was carried out between August 2012 and July 2013 enrolling 79 women with cancer cervix receiving chemo-radiotherapy. Weekly assessment of acute morbidity was done using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4 and the toxicities were graded. Results: Anemia [77 (97.5%)], vomiting [75 (94.8%)] and diarrhea [72 (91.1%)], leukopenia [11 (13.9%)], cystitis [28 (35.4%], dermatitis [19 (24.1%)] and fatigue [29 (36.71%)] were the acute toxicities noted. The toxicities were most severe in $3^{rd}$ and $5^{th}$ week. All women could complete radiotherapy except two due to causes unrelated to radiation morbidity; seven (8.86%) had to discontinue chemotherapy due to leukopenia and intractable diarrhea. Though there was no correlation between anemia and other toxicities, it was found that all with leukopenia had diarrhea. Conclusions: Chemoradiation for cancer cervix is on the whole well tolerated. Leukopenia and severe diarrhea were the acute toxicities that compelled discontinuation of chemotherapy in two women. Though anemia had no correlation with gastrointestinal toxicity, all of those with leukopenia had diarrhea.

Various immunotherapeutic modalities have been used based on the autoimmune pathogenic mechanisms of myasthenia gravis (MG). Cell-mediated immunity as well as auto-antibodies may play a role in the remission and relapse of MG. We recently experienced two patients with MG who showed spontaneous remission after inadvertent severe leukopenia. These findings suggest that the cell-mediated immune process is important in the treatment of MG, and selective suppression of leukocyte may induce remission in the patients with intractable MG.

The present study was designed to evaluate the effects of a recombinant human granulocyte-colony stimulating factor (G-CSF) on leukopenia and tumor growth in mice treated with DA-125, an adri-amycin (ADM) derivative. In normal mice, single intravenous injection of DA-125 produced transient leukopenia accompanied with weight loss and splenic atrophy in a dose-related manner. However, subcutane-ous administration of G-CSF (5$\mu$g/head) for 5 consecutive days after DA-125 resulted in a significantly elevated nadir of leukocyte counts and facilitation of recovery from the leukopenia. To investigate the effect of G-CSF on antitumor effects of DA-125, ADM (12 mg/kg) or DA-125 (40 mg/kg) was administered to Colon-26 murine adenocarcinoma-bearing Balb/c mice with G-CSF. Regardless of treatment with G-CSF, DA-125 and ADM markedly retarded the growth of implanted tumor, though they failed to increase mean survival time of tumor-bearing mice. These results suggest that G-CSF is able to not only ameliorate, but reconstitute DA-125-induced myelosuppression without affecting its antitumor potential.
