Abstract
Complications in anticoagulation therapy and long term consequences of the post thrombotic syndromes requires a fast and powerful therapy such as heparin therapy (anticoagulation) to minimize the thrombotic effects in patients. Thus, a simple approach via electrochemical method: Differential pulse polarography (DPP) has been developed for heparin analysis as a powerful clinical tool to monitor anticoagulation action in-patient undergoing heparin therapy. The method has been standardized for determination of heparin activity over the existing methods and a very well defined characteristic reduction peak at -1.25 V in 2 M NaOH was observed for heparin. A linear relation was observed with a regression equation as y = 0.3117x + 0.8069, for 0.1 to 2.0 units/ml heparin. The developed DPP method was observed with excellent precision, accuracy and recovery in human blood plasma samples and in pharmacological formulations. The limit of detection (LOD) and limit of quantification (LOQ) noticed to be 2.04 and 6.8 units/ml respectively. The DPP results compared with pharmacological screening through average thrombin time (TT) and applied to monitor invitro anticoagulation action of heparin in healthy human subjects. Statistical analysis done to validate developed DPP method for heparin analysis and its probable clinical use to monitor anticoagulation action to treat patients suffering from various cerebrovascular disorders (CVD) by proper dosing of heparin.

Abstract
Rh blood group system is a complex blood group system. Rh antibodies are produced in Rh negative individuals following exposure to foreign RBCs after transfusion or pregnancy. Anti C is a rare cause of hemolytic disease of newborn and is very scarcely reported in the literature. The aim of the present case report of Hemolytic disease caused by Anti C antibody is to bring out the fact that antibodies other than anti D should be considered in cases that give a suggestive history but no evidence of Anti D.

Abstract
We describe a 22-year-old male with idiopathic autoimmune thrombocytopenia whose diagnosis was made at age of eight. He underwent splenectomy at age ten and ITP recurred at age 21 with episodes of infection and severe neutropenia (absolute count around 170/μl). He showed no response to immunoglobulin, corticosteroids, danazol, cyclosporine and azathioprine. Anti-CD20 antibody was administered at a dose of 375 mg/m(2) once a week for 2 weeks. After the second infusion of rituximab, the platelet count increased from 4,000 to 516,000/mm(3) and neutrophils count raised from 180 to 545/mm(3). The response improvement persisted during follow up for 9 months (neutrophil count 4,390/mm(3)). This observation indicates that B-cells may play a central role in the pathogenesis of ITN. Anti-CD20 antibody therapy may be an efficient treatment for the patients with chronic or recurrent ITN.

Abstract
Acute leukemia (AL) displays characteristic patterns of antigen expression, which facilitate their identification and proper classification. The purpose of this study is to evaluate the diagnostic usefulness of commonly used immune-markers for immunophenotyping of AL and to define the best immune-markers to be used for proper diagnosis and classification of AL. Besides, to recognize the frequency of different AL subtypes and the antigen expression profile in our Egyptian patients. We retrospectively analyzed the immunophenotypic data of 164 de novo AL patients from our institution during 2009 and 2010. Among these patients, 68.9% were classified as acute myeloblastic leukemia (AML) while 31.1% classified as acute lymphoblastic leukemia (ALL). The commonest FAB subtype in AML group was AML-M4/5 (34.5%) which may differ from most published data. As regard ALL, there were 74.5% with B-ALL and 25.5% with T-ALL. It was found that combined use of HLADR and CD34 was much more helpful in distinguishing APL from non-APL AML than either of these antigens alone. It was found that cCD79a and CD19 were the most sensitive marker for B-ALL while cCD3, CD7 and CD5 were the most sensitive antigens for T-ALL. Our analysis of AL phenotypes proved that employed antibody panels are adequate for proper diagnosis and classification of AL. Flowcytometry was found to be especially useful in the identification of AML-M0 and differentiation of APL from non-APL AML. Immunophenotyping results and FAB classification of our AL patients were comparable to internationally published studies apart from predominance of AML-M4/5 and more frequent APL.

Abstract
PURPOSE To investigate the changes of color vision and central visual field in a cohort of patients with Vogt-Koyanagi-Harada (VKH) syndrome. METHODS Sixteen VKH patients (32 eyes) were enrolled in this study. All the patients were treated with immunosuppressive agents. The best visual acuity, visual field testing and color vision testing were available from the records in all these patients at different time points, i.e. before treatment and 1 month (±7 days), 3 months (±15 days), 6 months (±20 days) and 12 months (±30 days) after treatment. RESULTS All patients showed active intraocular inflammation at their first visit. A decreased visual acuity, abnormality of color vision and abnormal visual field were observed at presentation. Visual acuity and color vision rapidly improved at 1 and 3 months and gradually improved thereafter. Visual field defects significantly improved at 6 months and gradually improved thereafter. However, visual field defects were still observed in 27.5% of the tested patients following a 12-month treatment. Color vision returned to the normal level only in about one-third of these patients at this time point. CONCLUSIONS Visual function was severely impaired in VKH patients with active uveitis but rapidly improved following immunosuppressive therapy. Visual fields are much more severely affected by the disease than visual acuity and its improvement lagged behind that of visual acuity and color vision.

Abstract
The high prevalence of classic cardiac risk factors in patients with type 2 diabetes mellitus does not explain the increased cardiovascular related morbidity and mortality in these patients. Fibrinogen may have a role in this excess risk. This study is undertaken to know the fibrinogen levels in type 2 diabetes mellitus and its relations to glycemic control. In the present study fibrinogen levels (Clauss method) were estimated in 100 type 2 diabetic subjects and 100 age and sex matched controls. Fibrinogen was correlated with various parameters like glycosylated hemoglobin (cation exchange resin method), age, sex, smoking, body mass index (kg/m(2)), hypertension and ischemic heart disease. Higher plasma fibrinogen levels were found in type 2 diabetes mellitus patients (656 ± 130 mg/dl) as compared to controls (324 ± 139 mg/dl) which were statistically significant. Fibrinogen levels were associated with age (P < 0.01), hypertension (P < 0.01), body mass index (P < 0.01), smoking (P < 0.01), ischemic heart disease (P < 0.01), and glycosylated hemoglobin (r = 0.49) in diabetics in a significant manner. But no correlation was found with sex (P < 0.05) in diabetes. In controls, association was found between fibrinogen levels and smoking (P < 0.01) and body mass index (P < 0.01). Patients with type 2 diabetes mellitus had a high prevalence of hyperfibrinogenemia. Fibrinogen levels were independently associated with hemoglobin A1c values, which suggests that fibrinogen may be involved in the increased cardiovascular risk of patients with type 2 diabetes mellitus.

Abstract
Thrombocytopenia is a common feature among HIV-positive patients. However, there are few reports about this subject after highly active antiretroviral therapy (HAART) introduction. The authors show a retrospective description of epidemiology, clinical aspects, and treatment observed in 55 HIV-positive outpatients with thrombocytopenia treated in two reference centers for HIV treatment in São Paulo, Brazil. Thirty-four (62%) patients were male, 50 (91%) were Caucasian, with median of lymphocytes TCD4 of 394 cells/mm(3). In 63.6% patients, the cause of thrombocytopenia was classified as immune thrombocytopenic purpura and non immune in 25.5%. Regular use of HAART was present in 43.6% of the population studied. In 20% HAART was initiated for thrombocytopenia treatment with improvement in platelets count observed after 3 months. Platelet transfusion was needed in 23.7% of the patients and one patient died due to bleeding. Thrombocytopenia is still common among patients infected with HIV, considered a multifactor disorder, commonly due to immune mechanisms in our cases. In the clinical setting, a diagnostic approach related to the hematological consequences of HIV infection is needed for a better therapy option for this population.

Abstract
Imatinib inhibits constitutively active BCR-ABL tyrosine kinase of chronic myeloid leukemia (CML). In a long term study it was found superior to interferon alfa plus cytarabine for newly diagnosed CML in the chronic phase. However, till date there is no major study to evaluate eastern Indian CML patients treated with imatinib mesylate. The aim of our study was to see the efficacy, tolerability, toxicity and safety of imatinib in eastern Indian subset of CML population. The present study enrolled 831 patients with CML out of which 197 were excluded due to various reasons of noncompliance, death and not being fit to receive the drug. The rest, 634 (76% of total enrolled) were selected for the evaluation. In the beginning of the study, 603 patients were in chronic phase, 27 in accelerated phase and 4 patients in blast crisis phase. Among 634 patients, 280 patients (44%) received previously either interferon alpha or hydroxyurea and other 354 patients (56%) were previously untreated. Complete hematological remission and major cytogenetic response were 91 and 67%, respectively after 1 year of treatment. Complete molecular remission was 35% after 1 year of treatment. Sixty-four patients (10.1%) were resistant to imatinib mesylate in 5 years. The disease free and overall survival at 60 months were 72.2 and 76.1% respectively. After 60 months of follow up, continuous treatment of chronic phase CML with imatinib as initial therapy was found to be safe and able to induce durable responses in a high proportion of patients.

Abstract
To find the prevalence and causes of thrombocytopenia during pregnancy. An analytical prospective observational study was conducted in Department of Obstetrics & Gynecology, CSMMU, Lucknow. 1079 antenatal women screened for thrombocytopenia and investigated for cause and management strategies and fetomaternal outcome were recorded. Prevalence of thrombocytopenia was 8.8%. Gestational thrombocytopenia was seen in 64.2%, obstetric in 22.1% and medical in 13.68% cases. Mean platelet count in controls was lower with a significant fall (P < 0.001) in the platelet count as pregnancy advanced. Hypertensive and hepatic disorders were the most common obstetric causes of thrombocytopenia. Mode of delivery was not affected by thrombocytopenia. Maternal morbidity and mortality was seen only in medical and obstetric thrombocytopenia. The low platelet counts and declining trend with increasing gestational age predispose Indian women to risk of thrombocytopenia and a routine platelet count is suggested.

Abstract
Human Parvovirus B19 has been linked to a variety of diseases. One of the most common complications is transient aplastic crisis in patients with chronic hemolytic anemia. Very few case reports have implicated this virus as a putative etiology behind hepatitis and severe aplastic anemia in immuno competent individuals. We report a case of severe aplastic anemia in a previously healthy adult female due to acute parvovirus B19 infection. Laboratory examination showed pancytopenia in peripheral blood and severe hypoplastic bone marrow on biopsy. Serological analysis (ELISA) revealed acute Parvovirus B19 infection. In the face of unavailable HLA matched bone marrow donor, immuno-supressive therapy was contemplated, but could not be given because of financial constraints. Pancytopenia persists till date, 4 months after the diagnosis, with the patient requiring repeated packed red cell and irradiated platelet transfusions. Thus, acute infection with this virus must be considered a cause of acquired aplastic anemia even in individuals without underlying disease.

Abstract
Treatment of relapsed or refractory multiple myeloma remains a challenge and novel treatment regimen are required. Here, a matched pair analysis was performed comparing TCID (thalidomide, cyclophosphamide, idarubicin, dexamethasone) treatment to the treatment of patients with VID (vincristine, idarubicin, dexamethasone) or with VRID (vinorelbine, idarubicin, dexamethasone) for relapsed or refractory multiple myeloma. In total, 197 patients were enrolled in multicenter trials. After matching for important prognostic variables 46 matched-pairs (total of 138 patients) could be analysed with regard to survival, toxicity and efficacy. Interestingly, a significant improvement of overall response rate (ORR) for TCID treatment compared to VID and VRID was found. In addition, TCID treatment also led to a significantly higher overall survival (OS) as well as progression-free survival (PFS) compared to VID and VRID. In conclusion, TCID treatment appears to be superior to VRID and VID treatment in patients with progressive or refractory myeloma.
