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: Iron deficiency anemia (IDA) is one of the common nutritional disorders in the world. In the subcontinent Microcytic hypochromic anemia is usually caused by beta thalassemia trait (BTT) and iron deficiency anemia (IDA). IDA may be confused with BTT. It is important to distinguish between the above conditions to avoid unnecessary iron therapy in thalassemia carriers. Red cell distribution width index (RDWI) are a simple, easy, and cost effective method to get a primary and valuable information regarding the diagnosis of IDA and BTT. Objective: To assess the predictive value of Red cell distribution width index (RDWI)) for differentiation of Iron Deficiency Anaemia and Beta Thalassaemia Trait.Material & Methods:The study was a cross-sectional descriptive study which was conducted in Department of Clinical Pathology, Bangladesh Shishu Hospital and Institute, Dhaka, Bangladesh. Over a period of April 2019 to September 2020. The newly clinically diagnosed cases of BTT and IDA were selected for this study. The sample size was 110. Among them 46 cases were identified as BTT and 64 were IDA. Data were analysed using a computer programme SPSS 25.0 version.Results:Total 110 respondents were included in the study. Among them 46.4% were female and 53.6% were male. About 72.72 % of respondents were aged 1 to 10 years old, while 10% were aged 11 to 20 years old and 10% were aged 21 to 30 years old. 4.54 % were between the ages of 31 to 40, as well as those over 40. The average age (SD) was 22.0 � 32.52. Mean (盨D) age was 22.0 � 32.52. RDWI had both sensitivity and specificity more than 80% in detection of BTT and IDA. Sensitivity, specificity of RDWI index for detection of BTT was found 81.0%, 83.8%. In case of IDA, sensitivity and specificity was found 83.8% and 81.0% respectively.Conclusions:The current study found that multiple discriminants can be used to differentiate between iron deficiency anemia and the Beta Thalassaemia Trait. RDWI could be a better way to tell the difference between BTT and IDA.

RESUMO

Background: Multiple myeloma is a plasma cell neoplasm with acquired genetic abnormalities of clinical and prognostic importance, with survival duration ranging from a few months to more than 10 years. Cytogenetic abnormalities (CA) detected by fluorescence in situ hybridization (FISH) are of major prognostic significance since e.g. patients with del(17p), t(4;14) or gain 1q21 show dismal outcome. Objective: To evaluate the cytogenetic patterns by fluorescence in situ hybridization (FISH) of clinically diagnosed cases of multiple myeloma.Methods:This cross-sectional study was conducted in Department of Haematology, Dhaka Medical College Hospital, Dhaka, from January 2018 to December 2018. A total number of 30 patients with multiple myeloma were analyzed cytogenetically by interphase fluorescence in situ hybridization (iFISH). The collected data were analyzed by using the Statistical Package for Social Science (SPSS-24) for windows version 10.0.Results:Out of 30 diagnosed Multiple Myeloma cases the mean age was 56.37�.38 years and male to female ratio was almost 3:1. Sixteen (56.7%) of 30 patients. Among 30 cases of 8 cases were thyrogenicity positive of 7(23.3%) patients was detected del 13q positive. Isolated del 13q was found in 4 cases. 2 cases were found coexistence of del 13q and del 17p positive ;1 case was found coexistence of del 13q and t(4;14) positive and rest of 1 case had del 17 p positive. There was no detectable t (11; 14) and t(14;16) in any of 30 cases.Conclusion:FISH panel for Multiple Myeloma including del (13q); t(11;14); t(4;14), del(17p), t(14;16) is very important molecular test for the prognosis , risk stratification, treatment modality of the patient. On the basis of cytogenetic abnormality Multiple Myeloma risk stratification is modified now a day. This Revised International Staging system R-ISS is a simple and powerful prognostic staging system.
