Evaluation of transfusion-related complications along with estimation of inhibitors in patients with hemophilia: A pilot study from a single center |
p. 8 |
Anju Dubey, Anupam Verma, Priti Elhence, Prashant Agarwal DOI:10.4103/0973-6247.106714 PMID:23559756Background: Apart from inhibitor development in patients with hemophilia (PWH) the old problems of blood borne viral infections and red cell alloimmunization still persist in PWH from developing countries. This study was planned to detect the presence of inhibitors in our PWH and to determine the presence of transfusion transmitted infections (TTI) markers and clinically significant red cell alloantibodies in these patients. Materials and Methods: One hundred fourteen PWH were screened for various laboratory tests. Screening for inhibitors was done by mixing study. Blood grouping, TTI testing and red cell alloantibody detection were done as per the departmental standard operating procedures. Results: Out of 114 patients evaluated 98(86%) had hemophilia A and remaining 16(14%) had hemophilia B. Five (5.1%) patients of hemophilia A were positive on inhibitor screening. On Bethesda assay, one patient was high responder (14.4 BU/ml) and rest 4 were low responders (<5 BU/ml). Overall, 19 PWH were positive for TTI markers and two had clinically significant red cell alloantibody (anti-E and anti-Jk b ). Conclusion: This is probably first comprehensive study from our state on laboratory testing in PWH. The specialty of Transfusion Medicine can be a core part of hemophilia care. The overall prevalence of inhibitors in our hemophilia A patients was 5.1%, which is less as compared to majority of published studies. |

The effect of repeated freezing and thawing on levels of vitamin K-dependent coagulation factors and fibrinogen in fresh frozen plasma |
p. 11 |
Joseph Philip, RS Sarkar, Amardeep Pathak DOI:10.4103/0973-6247.106715 PMID:23559757Background: Fresh frozen plasma (FFP) is considered adequate for transfusion immediately after thawing or for up to 24 hours if kept at 1-6°C, and is currently used very often to replace deficient clotting factors. If factor levels in refrozen FFP are within normal limits, then this component can possibly be transfused, thus avoiding wastage of FFP. Aim: To study the fate of vitamin K-dependent coagulation factors (F II, F VII, F IX, F X) and fibrinogen activity levels in repeatedly (twice) frozen and thawed FFP. Materials and Methods: Two hundred FFP units comprising 50 units of each major blood group (A, B, AB, and O) were thawed at 37°C and 10-20 mL of FFP transferred to transfer bags with the help of a sterile connecting device (SCD). The FFP samples were taken into tubes (first sampling), and then the transfer bags were kept for 24 hours at 4°C. After 24 hours, repeat samples were taken in tubes from the transfer bag (second sampling), and then the bags were re-stored at < -18°C. One week later, the above procedure was repeated. Activity of coagulation factors and fibrinogen levels were measured by the automated coagulation analyzer. Results: The levels of F II, F VII, F IX, F X, and fibrinogen of all the 200 FFP units, at all four time points, were above the lower normal value, but well within the normal range. Conclusion: The levels of F II, F VII, F IX, F X, and fibrinogen remain stable and adequate for transfusion in twice-thawed-and-refrozen FFP. This component can be safely used for transfusion as a source of vitamin K-dependent clotting factors and fibrinogen. |

Frequencies and specificities of red cell alloantibodies in the Southern Thai population |
p. 16 |
Charuporn Promwong, Santi Siammai, Sarunya Hassarin, Jarin Buakaew, Tanongsak Yeela, Patravee Soisangwan, David Roxby DOI:10.4103/0973-6247.106718 PMID:23559758Context: Detailed reports of red cell alloantibody frequencies and specificities in the Thai population are limited. The aims of this study were to determine the specificity and compare the frequency of alloantibodies detected using column agglutination technology (CAT) and conventional tube techniques in blood donors and previously transfused patients. Settings and Design: We retrospectively reviewed antibody screening and identification records for two time periods: January-December 2006 during which conventional tube techniques were used and January 2008-December 2009 when CAT was used. Results: The overall prevalence of alloantibodies in both patients and donors when using conventional tube techniques was 0.7%, for patients only was 0.9% and donors 0.6%. The most frequent antibodies detected in both groups were anti-Lea, anti-Mia, anti-Leb, anti-P1 and anti-E. When using CAT, alloantibodies were found in 0.8% of patients and 0.13% of donors with the five most common alloantibodies found in patients were anti-Mia, anti-E, anti-Lea, anti-c and anti-Leb respectively. Similarly the common alloantibody specificities in donors were anti-Lea, anti-Mia, anti-Leb, anti-M and anti-D. Conclusions: One of the most commonly identified alloantibodies in the Thai population studied was anti-Mia suggesting that Mia positive red cells should routinely be included in antibody screening and identification in this population. For antibody screening and identification, CAT method detected immune and warm alloantibody (ies) more frequently than that associated with conventional tube techniques. |

Serological investigation for hepatitis E virus infection in the patients with chronic maintenance hemodialysis from southwest of Iran |
p. 21 |
Omid R Zekavat, Alireza Makarem, Mohammad Y Karami, Aida Amanat, Maesoomeh Mohandes, Mojtaba Habibagahi DOI:10.4103/0973-6247.106724 PMID:23559759Background and Objectives: A global distribution has been shown for hepatitis E virus (HEV) infection. Although the fecal-oral was considered as the primary infection route, there is controversial evidence for increased risk of the infection and consequent problems in patients on maintenance hemodialysis (HD) with suppressed immunity. The aim is to find if the prevalence of anti-HEV IgG, in patients with maintenance HD is higher than normal population in southwest of Iran. Materials and Methods: During November and December 2010, in a cross-sectional study we compared the seroprevalence of HEV among 80 patients with maintenance HD and 276 healthy individuals from Jahrom and Shiraz, Southwest of Iran. In addition to the clinical and laboratory records, serum samples were tested for the presence of IgG anti-HEV antibody by enzyme immunoassay (ELISA) test. The Chi-square, the Student's 't' and Fisher's exact tests were used for the statistical analysis. Results: ELISA tests detected anti-HEV antibody in five males of the patients (6.3%) and in eight of the healthy controls (2.9%, 6 males and 2 female) which statistically were not different. The mean levels of the aspartate aminotransferase and the alanine aminotransferase in the sera of the patients were 19.96±11.08U/L and 23.93±14.26 IU/L, respectively. However, no one of the individuals with positive anti-HEV antibody showed elevated liver enzymes. Moreover, there was not a significant association between positive anti-HEV antibody result, age and the history of the hemodialysis. Conclusions: We did not observe statistically significant higher anti-HEV prevalence among patients with chronic HD; however, more safety precaution is needed to keep HD patients from the risk of possible exposure to HEV infection. |

Prevalence of Diego blood group antigen and the antibody in three ethnic population groups in Klang valley of Malaysia |
p. 26 |
Cheong Tar Wei, Faisal Muti Al-Hassan, Norris Naim, Aishah Knight, Sanmukh R Joshi DOI:10.4103/0973-6247.106725 PMID:23559760Background: Diego blood group antigen, Di(a), is very rare among Caucasians and Blacks, but relatively common among the South American Indians and Asians of Mongolian origin. The antibody to Di(a) is clinically significant to cause hemolytic disease in a new-born or hemolytic transfusion reaction. Objectives: This study was designed to determine the prevalence of Di(a) antigen among the blood donors from the three major ethnic groups in Klang Valley of Malaysia as well as to find an incidence of an antibody of the Diego antigen, anti-Di(a), in a tertiary care hospital to ascertain the need to include Di(a+) red cells for an antibody screen cell panel. Materials and Methods: Serological tests were performed by column agglutination technique using commercial reagents and following instruction as per kit insert. Results: Di(a) antigen was found with a frequency of 2.1% among the Malaysians donors in three ethnic groups viz, Malay, Chinese and Indian. It was present among 1.25% of 401 Malay, 4.01% of Chinese and 0.88% of 114 Indian origin donors. None of the 1442 patients, including 703 antenatal outpatients, had anti-Di(a) in serum. Conclusion: The prevalence of Di(a) antigen was found among the donors of all the three ethnic background with varying frequency. Inclusion of Di(a+) red cells in routine antibody screening program would certainly help in detection of this clinically significant antibody and to provide safe blood transfusion in the Klang Valley, though the incidence of antibody appears to be very low in the region. |

Removal of antibodies from red cells: Comparison of three elution methods |
p. 29 |
Rahul Katharia, Rajendra K Chaudhary DOI:10.4103/0973-6247.106727 PMID:23559761Background: Direct antiglobulin test (DAT) is the most common test done in immunohematology lab, which detects immunoglobulin and fragments of complement attached to the red blood cells. These coated red blood cells are difficult to accurately phenotype, which may be required for selection of appropriate unit of red blood cells for transfusion. Aims: We have studied the efficacy of various elution methods in removing the antibodies coating the red cells and their impact on different blood group antigen activity. Materials and Methods: Patient samples sent for serological evaluation of autoimmune hemolysis were included in the study. DAT and Indirect antiglobulin test (IAT) were performed using gel cards (ID system, DiaMed Switzerland). Antibody coated red cells, either by in-vivo or in-vitro sensitization, were used to assess the outcome of three elution methods. Results: Out of 93 DAT positive samples already sensitized in vivo, 28 (30 %) samples became DAT negative post elution using either of three methods, while 36 (38.8%) showed reduction in strength of reaction, whereas in 29 (31.2%) there was no change in strength of reaction. Similarly, out of the 17 samples prepared by in vitro sensitization, 12 samples became completely negative after glycine-HCl/EDTA elution, 9 and 5 samples became negative after heat elution and chloroquine diphosphate elution methods, respectively. Conclusion: On comparative analysis glycine-HCl/EDTA elution method was better than the other two methods and can be used for eluting immunoglobulins from intact red cells. |

p. 33 |
Lamis A Ragab, Mona M Hamdy, Iman A Shaheen, Rania N Yassin DOI:10.4103/0973-6247.106728 PMID:23559762Background: Although red cell transfusions are lifesavers for patients with thalassemia, they are responsible for a series of complications and expose the patients to a variety of risks. Material and Methods: This cross-sectional study included 464 Egyptian beta(β) thalassemia major patients whose age ranged between 10 months and 31 years (mean 10.2 ± 6.6 years). All patients were subjected to thorough history taking with special emphasis on blood transfusions regarding rate of blood transfusion, type of received blood, and history of previous transfusion reactions in addition to type of chelation and compliance to iron chelation therapy and history of diabetes. Serum ferritin and pretransfusion hemoglobin assessment were done for all patients. Results: The mean pretransfusion hemoglobin level was 5.7 ± 1.16 g/dl. Allergic reactions were observed in 3.9% of the patients during the period of the study, while the history of previous allergic reaction was given by 72% of the patients. Deferiprone showed better compliance (58.6%) than deferoxamine (26.3%). The prevalence of diabetes was 10.1% among the studied group. On comparing diabetics to nondiabetics, serum ferritin, transfusion intervals, and age were statistically higher among diabetics (P<0.001). Conclusion: Lower pretransfusion hemoglobin and high rate of prevalence of diabetes, in addition to better compliance to deferiprone than deferoxamine, were detected among the patients. |

Adverse events associated with apheresis procedures: Incidence and relative frequency |
p. 37 |
Joseph Philip, Ravi S Sarkar, Amardeep Pathak DOI:10.4103/0973-6247.106730 PMID:23559763Introduction: Apheresis procedures [Plateletpheresis, Plasmapheresis/ Therapeutic Plasma Exchange (TPE), & Peripheral Blood Stem Cell Collection (PBSC)] are usually well tolerated. Occasionally, Adverse Events (AEs) of variable severity may occur during or after the procedure. AEs that occur in Donors/Patients are divided into local reactions and systemic reactions. Materials and Methods: A total of 3,367 apheresis procedures were performed, out of which 3,120 were plateletpheresis procedures, and out of which 1,401 were on Baxter CS 3000 & 1,719 were on Haemonetics MCS+ cell separators. Rest of 247 TPE & PBSC procedures were done on Haemonetics MCS+ cell separators. Results: 90 AEs were reported in relation to the 3,367 procedures. Out of 90 AEs, 85 AEs (94%) were associated with plateletpheresis (n = 3,120) and 05 AEs (06%) with TPE & PBSC (n = 247). The rate of vascular injury (VI), Citrate reaction (CR), and Presyncopal/Syncopal (PS/S) in plateletpheresis was 1.6% (52/3,120), 0.96% (30/3,120), and 0.096% (03/3,120), respectively. The rate of CR in TPE and PBSC was 1.23% (02/162) and 2.3% (02/85), respectively. The rate of PS/S in PBSC was 1.17% (01/85). AEs for Plateletpheresis, TPE & PBSC were 2.7% (85/3,120), 1.23% (02/162), and 3.5% (03/85), respectively. VI, CR, and PS/S were mostly of mild intensity. Both cell separators were equally safe, when AEs associated with plateletpheresis were compared with each other; 2.8% on CS 3000 & 2.6% on MCS+. Conclusion: Apheresis procedures performed on cell separators are safe, with a low incidence of significant AEs. No significant difference was noted in AEs among the two cell separators studied. |

p. 42 |
Kumkum Sharma, Sumit B Sharma, Imran A Pukhta, Amit B Sharma, Abdul Q Salaria DOI:10.4103/0973-6247.106733 PMID:23559764Introduction: To study whether the administration of recombinant human erythropoietin increases the amount of autologous blood that can be collected before orthopaedic surgery. Materials and Methods: We conducted a randomized controlled trial of recombinant human erythropoietin in 68 adults scheduled for elective orthopedic procedures. The patients received either erythropoietin 600 units/kg of body weight or placebo intravenously every 5 th day prior to each phlebotomy for 21 days during which time up to 5 units of blood was collected. Patients were excluded from donation when their hematocrit values were less than 33%. All patients received iron sulphate 325mg orally 3 times daily. The mean number of units collected per patient was 4.33 ± 0.4 for erythropoietin group and 3.05± 0.71 for the placebo group. Results: The mean packed red cell volume donated by patients who received erythropoietin was 32% greater than that donated by patients who received placebo (196.3 vs. 169.4 ml, p<0.05). 68% in the placebo group and 9% of patients treated with erythropoietin were unable to donate ≥4 units. No adverse effects were attributed to erythropoietin. While participating in the study, complications developed in 2 patients one in each group necessitating their removal from the study. Conclusion: We conclude that recombinant human erythropoietin increases the ability of the patients about to undergo elective surgery to donate autologous blood units. |

HGV-HCV/HBV co-infection in India: A pilot study |
p. 48 |
Amruta D Pathare, Anand S Deshpande DOI:10.4103/0973-6247.106734 PMID:23559765Background: Hepatitis G virus (HGV) is newly identified virus, transmitted by infected blood and blood products. Effect of HGV infection on liver diseases is not well known. Aims: Co-infection of HGV with hepatitis B virus (HBV) and hepatitis C virus (HCV) infection has been reported however; very limited data is available from India. Therefore, we have performed a pilot study for the presence of co-infection of HGV in chronic liver disease patients. Setting and Design: The study was performed in research laboratory at P.D. Hinduja National hospital and Medical research center, Mahim, Mumbai. Prospective study was designed. Methods and Materials: Forty HBV, HCV related chronic liver disease patients were studied. Forty randomly selected voluntary healthy blood donors visiting our blood bank were included as controls. Serum bilirubin, alanine aminotransferase (ALT), Aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were estimated. HGV infection was detected by using reverse transcriptase molony murine leukemia virus (M-MLV) with the help of HGV 340/625IC kit (Sacace, Italy). Results and Conclusion: One HCV positive patient had infection with HGV among 40 HBV/HCV chronic liver disease patients. |

Effect of transfusion on dizziness in anemic patients after elective off-pump coronary artery bypass graft surgery |
p. 51 |
Seyed Jalil Mirhosseini, Mehdi Haddad Zadeh, Sadegh Ali-Hassan-Sayegh, Naime Dehghan Dehnavi DOI:10.4103/0973-6247.106737 PMID:23559766Background: Neurological disorders are common complications following coronary artery bypass graft (CABG). Dizziness in convalescence period is of high importance because it can prolong patient's stay at the hospital and decrease in sense of rehealing. Transfusion indication is seen in hemoglobin levels <7 g/dl; however, dizziness has been frequently observed in patients with hemoglobin levels 7-10 g/dl and they have dramatic response to transfusion. Therefore, this study was designed to evaluate effect of transfusion on dizziness in hemoglobin levels of 7-10 g/dl to set a more accurate indication for transfusion in anemic patients after elective off-pump CABG. Materials and Methods: This clinical trial study was conducted on 90 patients undergoing elective off-pump CABG surgery from January to June 2011, in Afshar cardiovascular center, Yazd, Iran. Patients with hemoglobin levels of 7-10 g/ dl measured 48 h after CABG were included in this study and those who stayed in ICU more than 48 h were excluded. The subjects were randomly divided into two groups: the experimental group received packed cell according to study protocol while the control group did not receive packed cell. Hemoglobin concentration was measured at 48 h and 72 h after CABG and discharge time, respectively. Dizziness was evaluated 72 h after surgery. Data were analyzed by ANOVA, Chi-square, and Fisher's exact test for quantitative and qualitative variables. Results: The mean age of the patients was 63.5 ± 10.67 years, from all of patients in which 50 cases (55.6%) were males and 40 cases (44.4%) were females. Dizziness after surgery occurred in 35 cases (38.8%), of whom, 27 cases (62.8%) were in the control group and 8 cases (17%) were in the transfusion group. Significantly a difference in the incidence of dizziness was found between two groups (P = 0.001). Conclusion: Transfusion in hemoglobin levels of 7-10 g/dl can be useful to decrease dizziness in anemic patients after elective off-pump CABG; however, the guidelines in textbooks suggest transfusion after CABG to be in hemoglobin levels <7 g/dl. |

p. 55 |
Nasim Valizadeh, Shahin Nateghi, Mehran Noroozi, Sasan Hejazi, Fateme Aghanezhad, Afsaneh Akbarpoor Morad Ali DOI:10.4103/0973-6247.106739 PMID:23559767Background: Although, in the past the risk of transfusion transmitted viral infections were high in hemophilia patients, but introduction of viral inactivation methods in1985,decreased the risk of human immunodeficiency and hepatitis C and B viruses transmission significantly. The aim of study was seroprevalence of hepatitis B surface antigen (HBs Ag), hepatitis C virus antibody (HCV Ab) and human immunodeficiency virus antibody (HIVAb) in hemophiliacs in west Azarbaijan of Iran, born in 1985-2010. Materials and Methods: In a cross-sectional study, fifty patients with hereditary bleeding disorders born in 1985-2010, from total 250 patients who had been registered in Urmia Hemophilia Society were enrolled through the year 2010 to assess their seroprevalence for HCV Ab, HIV Ab and HBs Ag. Thirty five of 50 patients had hemophilia. Also; we performed a subset analysis for hemophilia patients. Results: All 50 patients with hereditary bleeding disorders including 35 patients with hemophilia were seronegative for HIV Ab and HBs Ag. HCV-Ab was detected in serum of 3 of 50 (6%) patients with bleeding disorders. After subset analysis for hemophilia (A and B) patients, we found HCV infection in 8.57% (3 of 35) of hemophiliacs. Conclusion: In this study prevalence of HCV infection was very smaller than similar studies in Iran and other countries. This study shows the safety of using viral inactivated factor concentrates and recombinant factors after year 1985.None of Hemophiliacs were seropositive for HIV Ab and HBs Ag. |

Knowledge, attitude and practices of people towards voluntary blood donation in Uttarakhand |
p. 59 |
Amit Agrawal, Aseem K Tiwari, Alok Ahuja, Rakesh Kalra DOI:10.4103/0973-6247.106740 PMID:23559768Introduction: Blood transfusions form a crucial and irreplaceable part in the medical management of many diseases. The collection of blood from voluntary, non-remunerated blood donors from low risk populations is an important measure for ensuring the availability and safety of blood transfusion. In a state like Uttarakhand which is visited by lakhs of visitors during pilgrimage season and where natural calamities and accidents are very common, the availability of blood is of utmost importance. Aim: To find out knowledge, attitude and practices of people towards voluntary blood donation to comprehend the situation and find ways to enhance voluntary blood donation in the state of Uttarakhand. Materials and Methods: Multi stage methodology was designed to target population including general population, influencers (doctors) and supporting organizations (camp organizers, State AIDS Control Society Officials) who were subjected to in-depth interview using pre-structured questionnaires to assess knowledge/awareness about voluntary blood donation, factors preventing and source of knowledge about voluntary blood donation. Result: The sample population consisted of mostly men (67%) in the age-group of 26-35 years. Requirement of blood and the measures to promote voluntary blood donation have a direct relationship with the total population and literacy level of the population. Awareness about blood donation, source of knowledge about blood donation, reasons for not donating blood are particularly stressed. With increase in educational level, the awareness level was also found to increase. While among illiterates 81 percent of the respondents knew about blood donation, among the post graduates the same ratio was found to be almost cent-percent. Among various reasons cited for not donating blood, lack of awareness being the most common reason. People gathered information about blood donation from several different sources with electronic media being the most prominent. Conclusion: This study illustrates how increasing awareness and marketing 'Voluntary blood donation' can enhance adequacy of blood needs of a state or for that matter the entire country. This study also underlines how different media, especially electronic media, can be used to propagate altruistic blood donation. |

Analysis of efforts to maintain safe donor in main donor pool after completion of temporary deferral period |
p. 63 |
Ripal Shah, Sunita Tulsiani, V Harimoorthy, Ankit Mathur, Nabajyoti Choudhury DOI:10.4103/0973-6247.106742 PMID:23559769Background: Voluntary blood donation is not satisfactory all over India. In India, about 55% of donation is through voluntary non-remunerated blood donors (VNRBD). However, about one third already motivated blood donors are deferred due to stringent screening criteria, either temporarily or permanently. The temporarily deferred donors could be a good source of blood donation after deferral period. Aims: The present study is carried out to know retrieval of blood donors those who are deferred temporarily. Design: The present study is carried out in the Regional Blood Transfusion Centre of Western India. All donors screened as per the guideline and deferred donors are categorized as temporary and permanently deferred donors. Materials and Methods: From temporarily deferred donors, reason for deferral is considered. As per reason of deferral, time duration for recalling the donor is defined. Based on this, donor is called back to donate again. Statistical Analysis: Chi-square test is applied. Result: A total of 33% donors were deferred either temporarily or permanently. In the repeat donors (5.32%) deferral rate was significantly higher than first time (1.32%) donors. Significant female preponderance was observed (15.05% vs 2.51%). Majority of temporarily deferred donors were less than 40 years of age (80.80%), graduate (82.90%), from low income group (62.90%) and profession was service (48.10%). Conclusion: Low hemoglobin (78.30%) was the most common reason of temporary deferral, both in first time and repeat donors (71.00%). Efforts to increase the hemoglobin in the repeat donors will improve the donor retention and overall blood safety can be increased. |

Perioperative use of allogenic blood components in live-related donor orthotopic liver transplantation: A cross sectional study |
p. 68 |
Prashant Pandey, Aseem K Tiwari, Jyoti Sharma, Divyajyoti Srivastava, Surbhi Dixit, Vimarsh Raina DOI:10.4103/0973-6247.106743 PMID:23559770Background: In spite of many improvements that have reduced the blood component requirements, substantial numbers of transfusions are still needed in liver transplantation. Aims: The objective of the present study was to analyze the perioperative usage of allogenic blood components and predict the preoperative factors as predictors of red cell transfusion in live-related donor liver transplant recipients. Materials and Methods: The retrospective data on utilization of allogenic blood components were analyzed for a total of 150 liver transplant procedures. The data on utilization of blood components during surgery and till 48 hours of ICU stay was collected from the blood bank record and hospital information system (HIS). Results: Red cell concentrate was commonest blood component used in liver transplant recipient and most of the transfusion took place during surgery. During intraoperative period 92.7% (N = 139) of the cases utilized red cell components with the median number of five whereas in postoperative period only 38% (N = 57) of patients received blood with the median number of one. This study demonstrates that the preoperative hemoglobin and platelet count are the predictors of utilization of red cell concentrates during surgery. There were a total of 11 (7.3%) recipients who didn't receive allogeneic blood transfusion in any form.Utilization of blood components was negligible among organ donors. Conclusion: Our study demonstrates the pattern and predictors of usage of allogeneic blood components in liver transplant recipients at a tertiary healthcare center in India. |

Hemovigilance Program-India |
p. 73 |
Akanksha Bisht, Surinder Singh, Neelam Marwaha DOI:10.4103/0973-6247.106744 PMID:23559771A centralized hemovigilance program to assure patient safety and to promote public health has been launched for the first time in India on Dec 10, 2012 in 60 medical colleges in the first phase along with a well-structured program for monitoring adverse reactions associated with blood transfusion and blood product administration. National Institute of Biologicals (NIB) will be the National Coordinating Centre for Hemovigilance. This program will be implemented under overall ambit of Pharmacovigilance Program of India (PvPI), which is being coordinated by Indian Pharmacopoeia Commission (IPC). All medical colleges of the country will be enrolled in this program by the year 2016 in order to have a National Centre of Excellence for Hemovigilance at NIB, which will act as a global knowledge platform. |

Dyspnea with anemia turned out to be a case of hereditary hemorrhagic telangiectasia |
p. 75 |
Amitabha Sengupta, Kaushik Saha, Debraj Jash, Sourindra N Banerjee DOI:10.4103/0973-6247.106745 PMID:23559772Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant inherited disorder of the vascular system. It can be asymptomatic but when symptomatic most common presentation being epistaxis. It can involve any organs of the body like lungs, skin, liver brain, GI mucosa etc. We are reporting a case of HHT presented to us with dyspnea and severe anemia. He had arteriovenous malformations of different visceral organs and telangiectasia of skin along with presence of similar history in first-degree relatives. |

Thrombotic thrombocytopenic purpura in the first trimester of pregnancy |
p. 79 |
Pooja Sikka, Seema Chopra, Neelam Aggarwal, Vanita Suri, Abi Chandrasekaran DOI:10.4103/0973-6247.106746 PMID:23559773Thrombotic thrombocytopenic purpura (TTP) occurs more commonly in women and so can be associated with pregnancy. The time during pregnancy with greatest risk for development of TTP is near term and during the post partum period. TTP occurring in early trimester is uncommon and is also associated with great maternal and fetal mortality. We report a successful outcome of pregnancy in a woman with TTP in early first trimester who was treated with therapeutic plasma exchange. |

IgE- and IgG mediated severe anaphylactic platelet transfusion reaction in a known case of cerebral malaria |
p. 81 |
B Shanthi, Bhavanadhar , Priscilla Chandran, A Krishna Prasad DOI:10.4103/0973-6247.106748 PMID:23559774Background: Allergic reactions occur commonly in transfusion practice. However, severe anaphylactic reactions are rare; anti-IgA (IgA: Immunoglobulin A) in IgA-deficient patients is one of the well-illustrated and reported causes for such reactions. However, IgE-mediated hypersensitivity reaction through blood component transfusion may be caused in parasitic hyperimmunization for IgG and IgE antibodies. Case Report: We have evaluated here a severe anaphylactic transfusion reaction retrospectively in an 18year-old male, a known case of cerebral malaria, developed after platelet transfusions. The examination and investigations revealed classical signs and symptoms of anaphylaxis along with a significant rise in the serum IgE antibody level and IgG by hemagglutination method. Initial mild allergic reaction was followed by severe anaphylactic reaction after the second transfusion of platelets. Conclusion: Based on these results, screening of patients and donors with mild allergic reactions to IgE antibodies may help in understanding the pathogenesis as well as in planning for preventive desensitization and measures for safe transfusion. |

Hemolytic disease of the fetus and newborn caused by anti-E |
p. 84 |
Adiyyatu Sa'idu Usman, Rapiaah Mustaffa, Noraida Ramli, Sirajo A Diggi DOI:10.4103/0973-6247.106750 PMID:23559775Objective: Maternal allo-antibody production is stimulated when fetal red blood cells are positive for an antigen absent on the mother's red cells. The maternal IgG antibodies produced will pass through the placenta and attack fetal red cells carrying the corresponding antigen. Allo-immune hemolytic disease of the fetus and newborn caused by anti-E rarely occurs. Case summary: We report two cases of anti-E hemolytic diseases in neonates. One of the neonates had severe hemolysis presenting with severe anemia, thrombocytopenia, and conjugated hyperbilirubinemia, while the other had moderate anemia and unconjugated hyperbilrubinemia. Although both the neonates were treated by phototherapy and intravenous immunoglobulin, one of them received double volume exchange transfusion. Conclusion: There appeared to be an increase in the occurrence of hemolytic disease of the fetus and newborn caused by Rh antibodies other than anti-D. In this case report, both patients presented with anemia and hyperbilirubinemia but were successfully treated, with a favorable outcome. |

Transfusion reaction in a case with the rare Bombay blood group |
p. 86 |
Hayedeh Javadzadeh Shahshahani, Mohamad Reza Vahidfar, Seyed Ali Khodaie DOI:10.4103/0973-6247.106754 PMID:23559776Bombay phenotype is extremely rare in Caucasian with an incidence of 1 in 250,000. When individuals with the Bombay phenotype need blood transfusion, they can receive only autologous blood or blood from another Bombay blood group. Transfusing blood group O red cells to them can cause a fatal hemolytic transfusion reaction. In this study, we report a case with the rare Bombay blood group that was misdiagnosed as the O blood group and developed a hemolytic transfusion reaction. This highlights the importance of both forward and reverse typing in ABO blood grouping and standard cross-matching and performing standard pretransfusion laboratory tests in hospital blood banks. |

Antibodies against high frequency Gerbich 2 antigen (anti-Ge2): A real challenge in cross matching lab |
p. 88 |
Ravindra P Singh DOI:10.4103/0973-6247.106758 PMID:23559777Transfusion management of patients' alloimmunized against high-prevalence erythrocyte antigens is often problematic in emergency situations. Gerbich (Ge) is very common blood group system and Gerbich-2 (Ge-2) antigen present in high frequency and outside Papua New Guinea population, Ge-2 negative population almost nil. To manage such kind of problems with real emergencies, implementation of rare donor registry program, cryopreservation of red cells of rare donors and biological cross matching to assess significance of these antibodies is warranted. |
