This study aimed to evaluate the prevalence of preoperative thrombocytosis and its prognostic significance in Thai patients with endometrial cancer. We retrospectively reviewed the medical records of 238 cases who had undergone surgical staging procedures between January 2005 and December 2008. Associations between clinicopathological variables and preoperative platelet counts were analyzed using Pearson's chi square or two-tailed Fisher's exact tests. Survival analysis was performed with Kaplan-Meier estimates. Univariate and Cox-regression models were used to evaluate the prognostic impact of various factors including platelet count in terms of disease-free survival and overall survival. The mean preoperative platelet count was $315,437/{\mu}L$ (SD $100,167/{\mu}L$). Patients who had advanced stage, adnexal involvement, lymph node metastasis, and positive peritoneal cytology had significantly higher mean preoperative platelet counts when compared with those who had not. We found thrombocytosis (platelet count greater than $400,000/{\mu}L$) in 18.1% of our patients with endometrial cancer. These had significant higher rates of advanced stage, cervical involvement, adnexal involvement, positive peritoneal cytology, and lymph node involvement than patients with a normal pretreatment platelet count. The 5-year disease-free survival and overall survival were significantly lower in patients who had thrombocytosis compared with those who had not (67.4% vs. 85.1%, p=0.001 and 86.0% vs. 94.9%, p=0.034, respectively). Thrombocytosis was shown to be a prognostic factor in the univariate but not the multivariate analysis. In conclusion, presence of thrombocytosis is not uncommon in endometrial cancer and may reflect unfavorable prognostic factors but its prognostic impact on survival needs to be clarified in further studies.

We report the case of a 16-month-old patient with chronic immune thrombocytopenia (ITP) patient who experienced delayed treatment-free response (TFR) after romiplostim treatment. He received intravenous immunoglobulin every month to maintain a platelet count above 20,000/µL for 2 years. Thereafter, he received rituximab and cyclosporine as second-line therapy, with no response, followed by romiplostim. After 4 weeks of treatment, the platelet count was maintained above 50,000/µL. Following 7 months of treatment, he discontinued romiplostim, and the platelet count decreased. His platelet counts remained above 50,000/µL, without any bleeding symptoms, 2 years after romiplostim discontinuation. This is the first report of TFR after romiplostim treatment in pediatric chronic ITP.

Purpose: This study investigated predictive factors for severe neonatal thrombocytopenia, which greatly increases the need for intensive care and is associated with a high mortality rate in premature infants. Factors adopted for prompt identification of at-risk newborns include blood test results and birth history. This study analyzed the relationship between the presence of severe neonatal thrombocytopenia and the mortality rate. The causes of thrombocytopenia in premature infants were also examined. Methods: This retrospective study evaluated 625 premature infants admitted to the neonatal intensive care unit (NICU) at Chung-Ang University Medical Center. The neonates were classified into 3 groups according to the severity of thrombocytopenia: mild ($100{\times}10^9/L{\leq}platelet<150{\times}10^9/L$), moderate ($50{\times}10^9/L{\leq}platelet<100{\times}10^9/L$), or severe (platelet<$50{\times}10^9/L$). Analysis of blood samples obtained at the onset of thrombocytopenia included platelet count, white blood cell (WBC) count, hemoglobin level, hematocrit level, absolute neutrophil count, and high-sensitivity C-reactive protein level. Results: Of the 625 premature infants admitted to our NICU, 214 were detected with thrombocytopenia. The mortality rate in thrombocytopenic neonates was 18.2% (39/214), whereas a mortality rate of only 1.0% was observed in non-thrombocytopenic neonates. The major causes of thrombocytopenia were perinatal insufficiency and sepsis in premature infants. Severe thrombocytopenia was noted more frequently in premature infants with higher WBC counts and in those with a younger gestational age. Conclusion: Platelet count, WBC count, and gestational age are reliable predictors for severe neonatal thrombocytopenia. The major causes of thrombocytopenia were perinatal insufficiency and sepsis in premature infants.

Platelets are derived from fragments formed in the cytoplasm of bone marrow megakaryocytes. Platelet count (PLT) can be altered by factors such as platelet production, destruction, and inflammation. In a previous study, the significant single nucleotide polymorphisms (SNP) were reported by the genome-wide association study (GWAS) for PLT in Koreans. In this study, it was confirmed whether significant SNPs were replicated in the HEXA (The Health Examinees) cohort. As a result, the SNPs of the THPO (rs6141), BAK1 (rs210314, rs9296095), GGNBP1 (rs75080135), ACAD10 (rs6490294), and ABCC4 (rs4148441) were significantly correlated with PLT (P < 10^-8). At the same time, it was confirmed that the direction of influence was the same according to the genotype. In conclusion, it can be seen that common SNPs are associated with the platelet count regardless of the cohort for Koreans.

Idopathic thrombocytopenic purpura(ITP) is the most common autoimmune hematologic disorder. The use of glucocorticoids and splenectomy have been the mainstays of treatment of ITP Some studies have shown that chinese herbal medicine treatment increase platelet count level of ITP patients. However, there is a lack of research considering oriental herbal medicine with ITP, in korea. A 33-year-old female who had diagnosed ITP on Mar 1999, was treated herbal medicine for decreased platelet count level$(34000/{\mu}l)$ that was identified on regular follow-up. this patient's platelet count level was get to normal$(139000/{\mu}l)$ by BuQiSheXue(補氣攝血) pattern herbal medicine that composed with Radix Astragali(黃?), Herba Agrimoniae(仙鶴草), Rhizoma Atractylodis Macrocephalae(白朮), Radix codonopsis(黨參), etc. I report the case with a review of literature.

목 적 : ALL 치료 중의 혈액학적 변화는 예후인자로써 뿐만 아니라 항암제의 용량을 결정짓는 중요한 변수이다. ALL의 유지요법 기간 중에 투여되는 vincristine의 용량은 저용량으로 혈소판수를 증가시키기에는 충분하다. ALL의 유지요법 기간 중에 vincristine 투여에 따른 혈소판의 변화를 알아보기 위하여 연구를 시행하였다. 방 법 : 가천의과대학교 길병원 소아과에서 고위험군 ALL로 진단받고 CCG-1882에 기초한 항암치료를 모두 마친 11명의 환아를 대상으로 유지요법 기간을 처음 6개월간의 초기, 마지막 6개월간의 후기로 나누어, vincristine 투여(0.05 mg/kg) 전과 투여 1, 2, 3주 후의 혈소판수를 비교 분석하였다. Vincristine 투여 전의 혈소판수를 100%로 하여 투여 후의 혈소판수를 percent로 환산하여 비교 분석하였으며, 투여 전에 비해 20% 이상 혈소판수가 증가한 경우를 의미 있는 증가로 하여 총례 및 각 개인별로 혈소판수를 비교 분석하였다. 결 과 : 유지요법 기간별로 혈소판수를 비교한 결과 유지요법 후기로 갈수록 전체 혈소판수는 증가하였으나 통계학적으로 의미 있는 차이는 없었다. 초기와 후기 모두 vincristine 투여 1주후 혈소판수는 최고가 되었다. 초기 6개월 유지요법 기간 중 vincristine 투여 전에 비해 투여 1, 2주 후에 통계학적으로 의미 있게 혈소판수가 증가하였으며 3주 후에는 투여 전 수준으로 되었다. Vincristine 투여 전에 비해 투여 1주 후에 혈소판수가 20% 이상 증가한 경우가 전체 11명 중 10명(90.9%)으로 통계학적으로 의미 있게 많았다. 후기 6개월 유지요법 기간 중 vincristine 투여 전에 비해 투여 1주 후에 통계학적으로 의미 있게 혈소판수가 증가하였으며 2주 후에는 투여 전과 비교해 통계학적으로 의미 있는 차이는 없었다. 후기에도 vincristine 투여 전에 비해 투여 후 혈소판수가 20% 이상 증가한 경우가 전체 11명 중 10명(90.9%)으로 통계학적으로 의미 있게 많았다. 결 론 : ALL의 유지요법에 사용되는 저용량의 vincristine은 투여 1주 후에 혈소판수를 최고로 증가시키며, 2-3주 후에 혈소판수는 투여 전 수준으로 돌아간다. 그러나 혈소판수의 증가는 혈전증을 일으킬 정도는 되지 않으며, vincristine에 의해 혈소판의 기능저하로 ALL의 항암요법의 유지요법 중 혈액 응고가 발생할 위험성은 낮아 보인다.

Aspirin is still the mainstay of antiplatelet therapy in the cardiovascular and cerebrovascular disease. However, some patients are not responsive to the antithrombotic action of aspirin. The aim of this study was to assess the prevalence and clinical characteristics of aspirin resistance in patients with cerebral infarction. We tested platelet function in 557 patients who had been treated with aspirin in J general hospital. Platelet function was tested using the multiple electrode platelet aggregometry (MEA). Platelet reactivity was expressed as area under the aggregation curve (AUC, U) and >30 AUC was defined as aspirin resistance. Aspirin resistance was detected in 16.2% patients. There was not any significant differences in age, gender between aspirin resistance and aspirin sensitive patients. WBC was significantly higher in patients with aspirin resistance (P < .05). HDL-cholesterol was significantly higher in patients with aspirin sensitive (P < .05). Aspirin resistance was positive correlation with platelet count (r =.314, P =.003). The prevalence of aspirin resistance in cerebral infarction was 16.2%, and platelet count were related with aspirin resistance.

Background: Sampling a healthy reference population to generate reference intervals (RIs) for complete blood count (CBC) parameters is not common for pediatric and geriatric ages. We established age- and sex-specific RIs for CBC parameters across pediatric, adult, and geriatric ages using secondary data, evaluating patterns of changes in CBC parameters. Methods: The reference population comprised 804,623 health examinees (66,611 aged 3-17 years; 564,280 aged 18-59 years; 173,732 aged 60-99 years), and, we excluded 22,766 examinees after outlier testing. The CBC parameters (red blood cell [RBC], white blood cell [WBC], and platelet parameters) from 781,857 examinees were studied. We determined statistically significant partitions of age and sex, and calculated RIs according to the CLSI C28-A3 guidelines. Results: RBC parameters increased with age until adulthood and decreased with age in males, but increased before puberty and then decreased with age in females. WBC and platelet counts were the highest in early childhood and decreased with age. Sex differences in each age group were noted: WBC count was higher in males than in females during adulthood, but platelet count was higher in females than in males from puberty onwards (P <0.001). Neutrophil count was the lowest in early childhood and increased with age. Lymphocyte count decreased with age after peaking in early childhood. Eosinophil count was the highest in childhood and higher in males than in females. Monocyte count was higher in males than in females (P <0.001). Conclusions: We provide comprehensive age- and sex-specific RIs for CBC parameters, which show dynamic changes with both age and sex.
