OBJECTIVETo investigate the prognostic value of thrombocytopenia in patients with primary myelodysplastic syndromes (MDS).

METHODSFour hundred and nineteen primary MDS patients were retrospectively analyzed. Kaplan-Meier method, Log-rank test and COX regression model were used to evaluate factors that influence the prognosis.

RESULTSTwo hundred and fifty-six cases (61.1%) had thrombocytopenia (PLT < 100×10(9)/L), one hundred and three cases (24.6%) had severe thrombocytopenia (PLT < 30×10(9)/L). Overall survival (OS) tended to shorten along with the decreasing of platelet count. Univariate analysis indicated that PL < 30×10(9)/L, MCV ≤ 95 fl, LDH ≥ 300 U/L, lymphocyte-like micromegakaryocyte, nucleated RBC PAS positive, IPSS cytogenetic intermediate- and poor-risk were all related with poor prognosis. Moreover, the prognosis of patients with RCMD, RAEB-Ior RAEB-IIwas poorer than that of the other subgroups. Among these parameters, PLT < 30×10(9)/L, MCV ≤ 95 fl, IPSS cytogenetic intermediate- and poor-risk group and RCMD, RAEB-I and RAEB-II had independent prognostic significance in multivariate analysis. Modified WPSS prognostic model was proposed by adopting PLT, MCV, chromosomal karyotype and WHO classification. The OS of patients with low risk, intermediate-1 risk, intermediate-2 risk and high risk were 59, 28, 14 and 4 months, respectively, and there was a statistically significant difference between the groups (P < 0.05).

CONCLUSIONSevere thrombocytopenia indicated unfavorable prognosis, in combination with MCV, chromosomal karyotype and WHO classification, a modified WPSS prognostic model was proposed and worked well for prognostic indication in patients with MDS.

BACKGROUND: The main causes of thrombocytopenia in cirrhosis are thought to be platelet destruction and the reduction of thrombopoietin (TPO) expression in the liver. Immature platelet fraction (IPF) has been measured by a fully automated analyzer (Sysmex XE-2100, Japan) as reticulated platelet (RP), which is reflected with thrombopoiesis in bone marrow. In this study, we tried to compare the percentage of IPF (IPF) with that of RP (RP) in patients with liver cirrhosis (LC) and controls. METHODS: We compared IPF to RP in 72 liver cirrhosis patients and 30 healthy normal controls. RP was stained with acridine orange, followed by FC500 (Beckman Coulter, USA) analysis and the IPF was identified by flow cytometry with the use of a nucleic acid specific dye in the reticulocyte channel on the Sysmex XE-2100 (TOA Medical Electronics Co., Ltd., Japan). RESULTS: IPF value in the healthy control was 2.2% (1.7-5.2). RP and IPF were significantly higher in the patients with liver cirrhosis (P<0.05). IPF appeared to be correlated with RP (y=0.19x+3.35, r=0.34, P<0.05). In ROC for diagnosis of LC, IPF was significantly more useful than RP. CONCLUSIONS: This results show that a rapid, inexpensive automated method for measuring the IPF is feasible and should become a standard parameter in evaluating reticulated platelets.

A 78-year-old man presented with an eight-hour history of chest distress. Electrocardiograph and serum cardiac enzymes were suggestive of acute inferior myocardial infarction with right ventricular infarction. The patient, who underwent emergency percutaneous coronary intervention, suffered from thrombocytopenia presenting with cerebral infarction and myocadial reinfarction during haparin exposure. The laboratory test for heparin-induced thrombocytopenia (HIT) specific antibodies (heparin-platelet factor, PF4) was positive. The case was diagnosed as arteries thrombosis due to heparin-induced thrombocytopenia; the patient died after cessation of heparin.

The association of thymoma with pure red cell aplasia has been well documented, but amegakaryocytic thrombocytopenia is not a recognized paraneoplastic syndrome complicating thymoma. We report a case of thymoma-complicated pure red cell aplasia and amegakaryocytic thrombocytopenia in a 73-yr-old woman. Pure red cell aplasia was diagnosed seven months after the detection of thymoma. One year after the diagnosis of pure red cell aplasia and seven months after thymectomy, bone marrow aspiration and biopsy showed an absence of megakaryocytes, marked erythroid hypoplasia with normal myeloid series. A diagnosis of amegakaryocytic thrombocytopenia and pure red cell aplasia was made. Oral steroid maintenance therapy resulted in recovery of platelet count. She has still transfusion-dependant anemia but platelet and neutrophil counts had been maintained in normal range for more than five months, until the last follow-up. We think that autoreactive T cells may induce a clinical autoimmune response even after eradication of thymoma, and aplastic anemia as a late complication following thymectomy was described in previous cases. This patient also has to be under a close observation because of the possibility to evolve into aplastic anemia.

BACKGROUNDChronic hepatitis C virus (HCV) infection can affect multiple organ systems and cause a variety of extrahepatic manifestations (EMs). We sought to assess the constituent ratio of EMs in Chinese patients with chronic HCV infection and identify the clinical and biological factors associated with EM.

METHODSThe medical records of 297 patients with chronic HCV infection were analyzed and demographic and epidemiological information was collected. The diagnosis of chronic HCV infection was based on positive anti-HCV combined with a positive HCV-RNA or at least two times of elevated aminotransferases attributable to HCV infection. Patients with HBV and/or HIV coinfection, autoimmune hepatitis, and history of alcohol abuse were excluded.

RESULTSSixty-two percent (184/297) of the patients had at least one EM, including fatigue (29.4%), type 2 diabetes mellitus (28.2%), renal involvement (12.5%), lymphadenopathy (9.6%), fever (9.4%), thyroid dysfunction (8.1%), and arthralgia (7.4%). Neuropathy, sicca syndrome, B-cell lymphoma, Raynaud's phenomenon, and lichen planus were rare. The mean age of patients with EM was older compared with those without EM.

CONCLUSIONSEMs were common in Chinese patients with chronic HCV infection, particularly fatigue, type 2 diabetes, renal impairment, lymphadenophy, fever, and thyroid dysfunction. Older age was associated with EMs.

Thrombotic thrombocytopenic purpura (TTP) in the acute postoperative setting is a syndrome that presents with various symptoms such as microangiopathic hemolytic anemia, thrombocytopenia, fever, renal failure, and change of the patient's mental status. Though most of the previous reports of postoperative TTP have been in conjunction with cardiac or vascular surgery, it has also been reported following orthopedic and abdominal surgeries. We present here a case of a 78 year-old female who was diagnosed with rectal cancer and who developed TTP the 2nd day following her cancer surgery. Because the presentation can be confused with other early postoperative complications, TTP should be considered in the differential diagnosis of the patient who develops unexplained anemia and thrombocytopenia following an abdominal surgery. Awareness of this syndrome is essential because starting plasmapheresis early can be life-saving.

Hepatitis A virus infection is the most common cause of acute hepatitis but is rarely reported during pregnancy. We report a case of acute hepatitis A in a 28-year old pregnant woman at 40 weeks of gestation. Her initial complaint was fever. Three days after, she developed spontaneous labor and delivered a healthy baby vaginally. Her laboratory examination showed thrombocytopenia, elevated D-dimer and decreased Fibrinogen level as well as markedly elevated liver enzymes. In addition, oliguria and pulmonary effusion were also noted. Hepatitis A infection during pregnancy may be associated with development of labor. And the differential diagnosis with preeclampsia and acute fatty liver of pregnancy is very important for the management.

OBJECTIVETo explore the relationship between continuous thrombocytopenia and sepsis in patients with severe burns.

METHODSClinical data of 148 severely burned patients admitted to our,two burn centers from January 2007 to December 2011 and conforming to the study criteria were retrospectively analyzed. All patients were divided into sepsis group (n =44) and non-sepsis group (n = 104) according to the presence or absence of sepsis within post burn day (PBD) 30. The data of age, gender, total burn area, full-thickness burn area, fluid infusion volume within post burn hour (PBH) 24, plasma concentration of calcium ion on PBD 1, plasma concentration of albumin on PBD 1, platelet count on PBD 1, acute physiology and chronic health evaluation (APACHE) II score on admission, the presence or absence of hypovolemic shock or inhalation injury on admission, the presence or absence of disseminated intravascular coagulation (DIC) within PBH 48, operation or no operation within PBD 3, thrombocytopenia duration within PBD 10, and mortality were statistically compared between two groups to screen the independent risk factors of sepsis. Data were processed with t test, chi-square test, single factor Logistic regression analysis, and multi-factor Logistic regression analysis.

RESULTSBetween two groups, there were statistically significant differences in total burn area, full-thickness burn area, plasma concentration of calcium ion on PBD 1, plasma concentration of albumin on PBD 1, APACHE II score on admission, presence or absence of hypovolem- ic shock on admission, presence or absence of inhalation injury on admission, presence or absence of DIC within PBH 48, and mortality (with t values from 2.433 to 4.082, χ2 values from 8. 818 to 31.528, P < 0.05 or P < 0.01). Furthermore, the duration of thrombocytopenia within PBD 10 in sepsis group was (5.2 ± 2.4) d, which was significantly longer than that in non-sepsis group [(2.9 ± 1.9) d, t =6. 189, P <0.01]. There were no statistically significant differences in the other indexes between two groups (with t values from 0.971 to 1. 250, χ2 values respectively 0. 054 and 1.529, P values above 0.05). Single factor and multi-factor Logistic regression analysis indicated that APACHE II score on admission and duration of thrombocytopenia within PBD 10 were closely related to occurrence of sepsis (with odds ratio respectively 1. 140 and 1.569, P values below 0.01).

CONCLUSIONSDuration of thrombocytopenia within PBD 10 is one of the risk factors for sepsis in severely burned patients, which can reflect pathophysiological changes in the body, thus providing predictive value for the occurrence of sepsis.
