RESUMO

Background: The fast-growing demand for platelet concentrates (PC) necessitates the storage of these blood products before transfusion. Platelets are prepared as concentrates from the whole blood or by plateletpheresis. Qualitative and quantitative assessment of these PCs is an important issue in transfusion medicine. To assess the qualitative, quantitative changes and bacteriological safety of 5 days of stored platelet concentrates (PC).Material & Methods:This prospective study was conducted at the department of Clinical Pathology in collaboration with the Department of Transfusion Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from April 2008 to April 2009. A total of 65 healthy donors were included in the study as per the inclusion and exclusion criteria. Therefore, 65 platelet concentrates (bags/units) were prepared from the donors. Purposive sampling of the units was done. pH and platelet indices (PLT, MPV, PDW and P-LCR) were measured and Gram staining of PCs was performed on days 0 and 5. Statistical significant tests were done at a 95% confidence interval using the statistical package for social science (SPSS).Results:The mean (±SD) pH was 7.18±0.07 ranging from 7.0 to 7.3 during day 0. On day 5 the mean (±SD) pH was 6.77±0.11 and their range was from 6.5 to 7. The mean pH difference was statistically significant (p<0.05) between day 0 and day 5. The mean (±SD) PLT/unit was 70.56±15.56 x109/unit and it ranged from 38.01 to 110.6 x109/unit during day 0. On day 5 the mean (±SD) PLT/unit level was 68.46±15.52 x109/unit and it ranged from 36.82 to 107.2 x109/unit. The mean PLT/unit difference was statistically significant (p<0.05) between day 0 and day 5. The mean (±SD) MPV was 9.34±0.92 fl and it ranged from 7.5 to 11.5 fl during day 0. During day 5 the mean (±SD) MPV was 9.27±0.99 fl ranging from 7.0 to 11.2 fl. The mean (±SD) PDW was 10.07±1.61 fl and which ranged from 7.4 to 14.4 fl during day 0. During day 5 the mean (±SD) PDW was 10.72±1.71 fl ranging from 7.0 to 15.4 fl. The mean (±SD) PLCR was 18.28±5.67 % and it ranged from 8.0 to 32.5 % during day 0. During day 5 the mean (±SD) PLCR was 21.18±5.91 % and it ranged from 10.0 to 36.3 %. The mean PLT, PDW and PLCR differences were statistically significant (p<0.05) between day 0 and day 5 in the unpaired t-test, however, the mean MPV difference was not statistically significant (p<0.05) between day 0 and day 5. Gram staining of platelet concentrates on day 0 and day 5 found no bacteria.Conclusions:Storage-induced lesions take place in PCs when stored for 5 days in second-generation storage containers under the currently recommended conditions, but how far these changes are clinically relevant needs to be investigated.

RESUMO

Background:ISCHEMIC HEART DISEASES continues to be a major public health problem becoming an increasingly important problem in developing countries constitutes around 12.8% of total deaths (7.2 million).Objectives:To evaluate the clinical course of ACS patient’s admitted to KIMS HUBLI ICCU. Material & Methods:Patients admitting to ICCU KIMS, HUBLI diagnosed as Acute Coronary Syndrome.The study included 156 patients admitted to ICCU KIMS Hubli who diagnosed as ACUTE CORONORY SYNDROME. Results:There wassignificant difference in the platelet indices betweenthe three groups. The platelet Indices -mean platelet volume, platelet distribution width and platicrit were significantly higher in STEMI and NSTEMI groups when compared to the USA group and severity of CAD more in patients who were having higher platelet indices. Conclusion:The platelet indices: mean platelet volume (MPV), platelet distribution width (PDW) and platecrit are significantly higher in STEMI and NSTEMI groups when compared to USA group.

RESUMO

Background: Thrombocytopenia (TCP) is low platelets count, which is either due to defective platelet production or due to increased platelet breakdown. The platelet number alone does not give a complete picture of platelet maturity and function, therefore, the platelet indices have been the subject of intensive study in recent years, but they have not been firmly established. Mean platelet volume (MPV) and platelet distribution width (PDW) are useful parameters in evaluating disorders of platelets. This study was undertaken to evaluate the effectiveness of PDW in diagnosing causes of thrombocytopenia. Methods: 510 cases of thrombocytopenia and 500 cases of Control group with normal platelet count were included in the study. TCP was defined as platelet counts below 1.5 lacs/cumm. Hematological analysis was done on Mindray BC-3000 plus automated hematology analyzer. All cases were reevaluated by peripheral smear examination. Only those cases were included in the study, which showed platelet count and platelet volume parameters with graph both in cases and in control group. Results: Hyper-destructive group constituted majority of the cases 352 (69%), while hypo-productive group and abnormal pooling constituted 30% and 1.42% cases respectively. The mean PDW was significantly higher in hyper-destructive group when compared with hypo-productive group, Abnormal pooling and control group. The difference was statistically significant. Conclusion: PDW provides plenty of clinical information about the causes and patho-mechanisms of thrombocytopenia and could be helpful to distinguish hyper-destructive thrombocytopenia from hypo-productive thrombocytopenia. More attention should be paid to PDW along with other platelet indices to differentiate between hyper-destructive TCP from hypo-productive and abnormal pooling TCP.

RESUMO

Background: The objective of the study is to estimate platelet volume indices in patients of cerebral ischemic vascular disease. Methods: The present study was conducted on 170 subjects in Department of Medicine, NIMS Medical College and Hospital, Jaipur, Rajasthan over eighteen months. The study was conducted on 60 patients admitted in the wards and ICU under the Department of Medicine and 110 controls who were the normal and healthy during the study period. In this study the values of platelet indices – MPV, PDW and platelet count were observed in patients of cerebral ischemia. It was found that large platelets contribute to the prethrombotic state in ischemic syndromes and they may play a specific role in infarction. Because larger platelets are haemostatically more active and hence, their presence is probably a risk factor for developing thrombosis. Statistical analysis was done using Chi – square test, unpaired ‘t’ test and ANOVA test. A p value <0.05 was considered statistically significant. Results: In this study it was found that in cerebrovascular disease patients, MPV was 10.30±0.83 fL, PDW was 14.50±0.55 fL, platelet count was 260×109 ± 29×109 /L while in control, MPV was 8.14± 0.72 fL, PDW was 10.71±0.48 fL, platelet count was 285×109 ± 50 ×109 /L. MPV and PDW were higher and platelet count lower in cerebrovascular disease group and a highly significant difference (p<0.001) was found on comparing with controls. Conclusion: In this study, it was found that MPV and PDW were raised in cerebrovascular disease suggestive of statistically highly significant when compared to normal control group.

RESUMO

Background: Platelet volume parameters are significant especially in diagnosis of causes of thrombocytopenia. The platelet parameters are widely available as part of full blood count with no extra cost. Thrombocytopenia is of varying etiology based on which it is broadly divided into three major categories (1) as increased destruction, (2) decreased production and (3) splenic sequestration/abnormal pooling. The present study was undertaken to understand relation between cause of thrombocytopenia and Platelet Distribution Width as well as other platelet parameters. Materials and Methods: 500 cases of Thrombocytopenia (TCP) and 300 control cases having normal platelet count were selected. TCP was defined as platelet count <1.5lakh/ìl. Analysis was done by Sysmex KX 21 cell counter and every case was reassessed by Peripheral Smear (P.S.) examination and if necessary also by manual method. Only those cases that had sufficient clinico-hematological work -up and the causes of low platelet count had been reliably established were included in the study. Results: The study was conducted on 500 cases they were broadly categorized into three groups Group A with accelerated platelet Destruction Group B with Impaired production and Group C with abnormal pooling. Out of 500 cases 272 (54%) were male and 228(46%) were female. A slight male preponderance was seen in overall picture as well as in almost all age groups. The overall male to female ratio being 1.19 : 1. Mean platelet volume [MPV] was statistically significant with ‘p’ values
