Abstract
OBJECTIVE To investigate the epidemiological characteristics and risk factors for syphilis in Huzhou City, and to provide data to support the design of more effective health counselling and screening measures for blood donors. METHODS A retrospective study was conducted to analyse the demographic characteristics and seropositivity of syphilis among blood donors from 2019 to 2021. The differences in the serological status of syphilis among different populations under different demographic factors were compared, and conditional logistic regression analysis was used to identify the risk factors for syphilis. RESULTS The seropositivity rate of syphilis among blood donors in Huzhou City was 133/100,000, which decreased year by year. There were significant differences in the syphilis seropositivity rate among different groups in terms of age, education level, occupation, household registration, marital status and blood donation history (P < 0.05). The multivariate logistic regression model showed that all six factors, including age, education level, occupation, household registration, marital status and blood donation history, had significant effects on syphilis infection (P < 0.01), with OR values and 95% CIs of 2. 387 (1.381-4.127), 3.607 (1.609-8.086), 2.784 (1.657-4.679), 5.074 (1.865-13.804), 11.177 (3.481-35.888), and 11.244 (3.940-32.091), respectively. CONCLUSION There is room for improvement in pre-donation health counselling and screening of high-risk populations. Timely monitoring and updating of demographic data for specific high-risk populations is essential.

Abstract
The maintenance of an adequate and safe blood supply begins with choosing the right donor at the right time. The evolution of donor screening has been shaped by experience, donor satisfaction, and the ever-challenging emergence of relevant infectious diseases. Screening donors has been standardized over the past 6 decades to protect donor and recipient safety. In this review, we outline, define, and simplify the requirements to assess and defer donors with a focus on recent and ongoing changes to provide up to date information on donor qualification and current challenges in maintaining the blood supply.

Should We Stop Collecting the Preoperative Autologous Blood before Bone Marrow Harvest? J Clin Med 2021; 10:jcm10102134. [PMID: 34069241 PMCID: PMC8156284 DOI: 10.3390/jcm10102134] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 05/02/2021] [Accepted: 05/10/2021] [Indexed: 01/05/2023] Open
Abstract
Preoperative autologous blood donation (PAD) in bone marrow (BM) donors is performed to meet potential post-harvest transfusion needs and to avoid the risk of allogeneic transfusions. We reviewed retrospectively bone marrow harvests in 216 healthy donors during a ten-year period to determine the use of autologous blood. All donors except four had undergone PAD. The initial hemoglobin level of 153 g/L (male donors) and 135 g/L (female donors), respectively, decreased by about 8 g/L after preoperative blood donation and by 23 g/L after bone marrow harvest (medians). Autologous blood was administered to 70% of donors, 30% of the units remained unused. The evaluation of the risk of reaching transfusion threshold (<115 g/L males, <105 g/L females) revealed that donors with initial hemoglobin above 145 g/L and those weighing above 75 kg have minimal risk of requiring blood substitution (about 10%). A larger volume of bone marrow was obtained from male compared to female donors (1300 vs. 1100 mL) because of their higher body weight, which resulted in a higher number of procured nucleated cells (362 vs. 307 × 106/kg TNC, ns). The donor-recipient weight difference predicted the probability of sufficient collection. Only 1.5% of donors weighing ≥ 20 kg more than recipients failed to reach ≥3 × 108/kg TNC recipient. Our findings affirm previous data that PAD is unnecessary for healthy marrow donors and may be indicated individually after considering the pre-collection hemoglobin level, donor and recipient weight, and expected blood loss. Reasonable substitution cut-offs have to be set together with clinical symptom evaluation. The effective use of PAD also requires an adequate time interval between PAD and BM harvest.

Abstract
BACKGROUND Although Hematopoietic Stem Cells (HSC) donation through bone marrow (BM) and peripheral blood (PB) are usually safe procedures, adverse events are expected. One of the most common events especially among BM donors (BMD) is the development of anemia. To protect the BMD and preserve the hemoglobin levels, many centers collect autologous pre-procedure blood, but the actual benefits of this procedure is controversial. METHODS AND MATERIALS This study analyzed retrospectively data to observe what factors may influence the occurrence of post-donation anemia and also evaluate the relevance of autologous red blood cell pre procedure donation (PAD). RESULTS The development of immediately post donation anemia (IP) was higher in BMD than in PB donors (64.2% BMD and 10.7% PBD, P < .001) and also in late post donation (LP) (28.4% BMD and 3.6% PBD, P = .007). The study demonstrated an association between PAD and anemia in IP (72.7% with anemia and 27.3% without anemia, P = .006) and an association between the volume of red blood cells in the donated hematopoietic product and the development of anemia in LP (356.3 mL and 297.8 mL, P = .037). CONCLUSION In conclusion, collection of HSC through BM is a risk factor for anemia and PAD is a risk factor for IP anemia.

Abstract
Pre-harvest autologous blood collection from bone marrow (BM) donors is performed to meet potential post-operative transfusion needs. This study examines the impact of autologous blood transfusion on BM donor's health and safety. The study included first-time unrelated BM donors from the United States whose BM harvest was facilitated by the National Marrow Donor Program (NMDP) centers between 2006 and 2017. Examination of 7024 BM donors revealed that 60% received at least one unit of autologous blood. The donors who received autologous blood were older, had lower hemoglobin pre-harvest, underwent longer duration of anesthesia, and higher volume BM harvest. Only donors who underwent high-volume BM harvest, defined as a BM harvest volume >27% of donor's blood volume, benefited from autologous transfusion. After a high-volume BM harvest, autologous blood transfusion was shown to decrease grade 2 to 4 collection-associated toxicities within 48 h of BM donation (p = 0.010) and shorten the time to donor-reported "complete" recovery from donation-associated symptoms (p < 0.001). Therefore, autologous transfusion could be avoided as support of marrow donation in the majority of unrelated BM donors and should be limited to cases where the planned BM harvest volume is expected to exceed 27% of donor's blood volume.

Clinical significance of autologous blood transfusions in bone marrow harvest from unrelated donors. Int J Hematol 2020; 111:833-839. [PMID: 32172447 DOI: 10.1007/s12185-020-02851-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2019] [Revised: 03/01/2020] [Accepted: 03/01/2020] [Indexed: 12/31/2022]
Abstract
In the Japan Marrow Donor Program (JMDP), autologous blood is collected from most unrelated bone marrow (BM) donors. We retrospectively evaluated 5772 donors who underwent BM harvest between 2010 and 2015 through the JMDP. Autologous blood was collected in 96.8% of the donors; the wastage rate was 0.6%. Allogeneic blood transfusion was not required. The mean hemoglobin (Hb) levels were 12.1 g/dL after the BM harvest (mean 891 mL) together with autologous blood transfusion (mean 596 mL). Propensity-score matching was used to adjust the backgrounds. Among donors with harvested BM of 100-400 mL, autologous blood transfusion had no impact on Hb levels or complications after BM harvest. Among donors with harvested BM of > 400 mL, more autologous blood transfusion followed by a bleeding volume of ≤ 100 mL did not confer clinical benefit to donors compared with less autologous blood transfusion followed by a bleeding volume of > 300 mL. The findings of the present study suggest that autologous blood transfusion to BM donors is excessive in terms of Hb changes and post-harvest outcomes.

Abstract
To avoid risk for allogeneic transfusions in healthy bone marrow (BM) donors, 1-2 preoperative autologous blood donations (PAD) are usually collected before the BM harvest. We analysed the haematological parameters in BM donors before and after the harvest, to assess the efficacy of this practice in limiting the postharvest anaemia. Overall, 102 consecutive donors underwent BM harvest preceded by one (26 cases) or two PAD (76 cases), which were infused during BM collection. We analysed the parameters related to donors, PAD timing and BM graft characteristics. PAD induced a significant decrease in Hb (from 14·6 g/dl, IQ range 13·3-15·5 to12·9 g/dl, IQ range 11·8-13·9; P < 0·0001) in all donors, with a median Hb loss at day -1 of 10·9% (IQ range 6·8-14·2). The PAD-related Hb decrease was independent of sex or number of PAD, and was inversely related to the time elapsed from first or last PAD. In comparison with values recorded at day-1, BM harvest produced an additional Hb decrease, accounting for a median Hb loss of 18·9% (IQ range 14·9-24·4). Overall, in comparison with pre-PAD values, Hb levels at day +1 were reduced of 28·9% (IQ range 23·6-32·2), independently if donors had 1 or 2 PAD reinfused. In conclusion, these data show that two PAD do not carry any advantage over one PAD. An eventual benefit of PAD can be achieved only if an adequate interval between PAD and BM harvest elapses. Prospective randomized studies could be worth to establish if any role for PAD does exist in BM donors.

Abstract
Background High-risk population of blood donation increases the prevalence of transmit blood-borne diseases and harm the blood safety. Syphilis accounts for approximately 10% of commonly sexually transmitted diseases. The risk factors for blood donors infected with syphilis are also risk factors for other blood borne diseases. The objective of the study is to investigate the seroprevalence and risk factors on syphilis among blood donors, and analyze the donation status of high-risk population. Methods A retrospective study was conducted in Chengdu Blood Center during 2005 and 2017. Serological test results of volunteer blood donors were collected. Conditional logistic regression models were performed to investigate syphilis-related risk factors and population attributable risk (PAR) was performed to predict the tendencies of high-risk populations’ on risky behaviors. Results The serological epidemic for syphilis among blood donors in Chengdu showed an upward trend from 2005 to 2017.TP positive blood donors were more likely to have multiple sexual partners and commercial sex (50.6% vs.22.6, 11.1% vs.4.6%). Multiple condition logistic regression model denoted the following risk factors for increasing rates of syphilis infections: multiple sexual partners (OR = 7.1, 95% CI:1.72–6.58), razor reuse (OR = 1.7;, 95% CI:1.01–2.01); ear piercing (OR = 2.7, 95% CI:1.48–3.37); tattoo (OR = 3.3, 95% CI:1.17–6.78); condom occasionally (OR = 2.8, 95% CI:0.68–1.66). The PAR for each of the risk factors were 0.225, 0.144, 0.147, 0.018, 0.129, 0.018, respectively. Conclusion Health consultation and screening of high-risk groups before blood donation need to be further improved. Blood donor recruitment should emphasize on excluding the high-risk donors and recruiting more low-risk blood donors. In addition, this study also shows that sharing cosmetic surgical instrument has been proven to transmit blood-borne diseases. Therefore, the syphilis in blood circulation should not be ignored.

Revisiting old practices: More restricted indication of preoperative autologous blood donation in healthy bone marrow donors according to baseline hemoglobin levels. Transfus Apher Sci 2019; 58:323-325.

Abstract
There is no consensus on the risk-benefit status of preoperative autologous blood donation (PAD) for healthy bone marrow donors and there is concern regarding its impact on the development of pre-surgical anemia. We evaluated the changes in hemoglobin levels related to PAD in 80 bone marrow donors of our institution between 2002 and 2016. Mean Hgb values were compared separately for donors who donated 1 or 2 units, at 3 time-points: before PAD collection, the morning before marrow harvest and soon after harvest. Mean baseline Hgb values did not differ significantly between the 2 groups. After PAD collection, there was a significant drop in Hgb levels for the whole cohort of donors but more pronounced for the group that donated 2 units [1 unit: 12.8(8.9-17.4) × 2 units: 11.55(11.2-12.1), p = 0.045]. However, after marrow harvest, Hgb levels were similar for the 2 groups; 61.2% of all donors required autologous transfusion and none required allogeneic transfusion. Furthermore, baseline Hgb <14.35 g/dL was identified as the sensitive cutoff to predict the need for transfusion after marrow harvest (sensitivity of 52% and specificity of 80.4%, p = 0.001). Thus, our analysis demonstrates the possibility of using hemoglobin thresholds as cutoff points for indication of PAD, tending to a more cost-effective approach. Despite significant declines in Hgb levels after PAD, none of the donors in our cohort required allogeneic transfusion, demonstrating the safety of this procedure. Thus, the indication of PAD remains an option for those who feel insecure despite higher baseline Hgb levels.

Abstract
Background Preoperative autologous blood donation (PABD) has been declining in use nationally. A subset of patients scheduled for elective surgery, however, continue to be offered and choose this option. Our study aimed to understand the current impact of PABD before scheduled surgical procedures. Study design and methods A retrospective review was conducted in a single large academic center. Medical records associated with autologous units received in the transfusion service over a two-year period (1/1/2016-12/31/2017) were reviewed. Demographics, units donated, units transfused, wastage, pre-donation hemoglobin (Hb), pre-operative Hb, estimated blood loss (EBL), and clinical specialty were collected. Results During the study period, 118 patients underwent PABD, donating a total of 141 autologous red blood cell units. Patients who donated autologous units and were subsequently transfused had lower pre-donation Hb compared to patients who were not transfused (13.3 ± 1.4 g/dL vs. 14.3 ± 1.5 g/dL, p=0.004). Pre-operative Hb was lower than pre-donation Hb among both groups (12.1 ± 1.2 g/dL for patients receiving transfusion; 12.9 ± 1.5 g/dL, p=0.011 for patients who were not transfused). The majority of PABD patients (71%) had an estimated blood loss of less than 500 mL. Wastage rate of autologous units was 67%. PABD was disproportionately associated with a minority of surgeons and clinical services. Conclusion Within our institution, PABD is heavily used amongst a small subset of physicians across multiple surgical specialties and is associated with lower pre-operative Hb, tendency towards overtransfusion, and high rates of wastage of donated units. Our findings reinforce reports of inefficiencies in patient blood management and increased risks to patient health associated with PABD.

Abstract
BACKGROUND Bone marrow harvest (BMH) for haematopoietic stem cell transplantation is a well-established procedure. The guidelines of World Marrow Donor Association provide information on donor selection. However, some of the guidelines regarding donors with anaemia prior to harvest lack in supporting data from clinical studies. With this study, we aimed to provide such data. MATERIAL AND METHODS In this retrospective, single-centre study, we analysed the interplay between haemoglobin levels and BMH and BMH impact on haemoglobin levels in a cohort of 149 unrelated BM donors, including 13 subjects with mild anaemia. RESULTS The BMH led to significantly lower decrease in haemoglobin levels in donors with anaemia than in control group (1·79 g/dl vs. 2·56 g/dl, P < 0·0001). The following parameters: BMH volume (ml), BMH volume/donor body weight (ml/kg), total nucleated cells (TNC) in product (×108 ) and TNC/kg recipient body weight in product (×108 /kg) did not differ significantly between those two analysed groups (P > 0·05). Median BM volume harvested from anaemic donors was 16·34 ml/kg; none of them required blood transfusion after BMH. CONCLUSION Mild anaemia prior to BMH does not significantly impact the collection results. The BMH is safe and feasible in donors with mild anaemia.

Arora K, Kelley J, Martinez F, Tholpady A. Preoperative autologous blood collection before bone marrow harvests in haploidentical related donors: is it justified? Transfusion 2018; 58:1618-1625. [PMID: 29577348 DOI: 10.1111/trf.14599] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2017] [Revised: 02/07/2018] [Accepted: 02/12/2018] [Indexed: 01/28/2023]
Abstract
BACKGROUND With the increasing safety of allogeneic blood supply and declining need for transfusion due to patient blood management, the practice of preoperative autologous donation (PAD) continues to decline. The practice gained popularity during the 1980s and 1990s with the emergence of transfusion-transmitted human immunodeficiency virus and hepatitis C. At the peak of this public concern, the National Marrow Donor Program recommended that marrow donors have 1 to 3 autologous units of blood collected before their marrow harvest to minimize the likelihood of allogeneic transfusion. After three decades, the practice remains prevalent in marrow donors. We aimed to study the efficacy of PAD in healthy marrow donors. STUDY DESIGN AND METHODS PADs performed before marrow harvest in healthy donors at our center between January 2013 and July 2015 were reviewed. The utilization of autologous units and decrease in hemoglobin levels due to PAD and marrow harvest were studied. Similar practices were assessed in the rest of the United States through a brief survey. RESULTS Of a total of 262 autologous units collected from 136 donors, 25.2% were wasted. Ninety-nine percent of the marrow donors received at least 1 unit of blood irrespective of the need. PAD contributed to preoperative anemia, exposing three donors to allogeneic blood transfusion. The survey results showed a mixed response with some institutions continuing and others not practicing PAD. CONCLUSION PADs are not justified in healthy marrow donors as they expose them to a risk of preoperative anemia and hence a greater risk of transfusion.
