Abstract:
On June 14, 1868, Karl Landsteiner, an outstanding scientist, known for his works in the field of immunohematology and immunochemistry, who received the Nobel Prize for the discovery of blood group systems in 1930, was born in a Viennese family. In 1900, Karl Landsteiner published a work in which he described in detail the process of agglutination that occurs when the blood plasma of one person is mixed with the red blood cells of another one. At that time, the scientist came to the conclusion that this phenomenon was of an immunological nature. In 1901, Landsteiner decided to divide human blood into three subgroups: A, B, and C; a little later, the AB group was added to them, while the C group was renamed as O. In addition, it was Landsteiner who invented a fairly simple scheme that allows developing and introducing the basic principles of blood transfusion into wide practice, and the world got a wonderful opportunity to save hundreds and thousands of human lives. Thanks to this discovery, made more than 100 years ago, more than 100 million donations are made every year around the world, more than half of which are in developed countries with high living standards and incomes. Here people come to blood donation deliberately, and not for the sake of receiving financial or any other benefit. Thanks to blood transfusion, it became possible to successfully carry out many surgical interventions accompanied by the loss of a large amount of blood, exchange blood transfusion for hemolytic disease of newborns, and substitution therapy for many pathological conditions. Karl Landsteiner’s work was highly appreciated: in 1930, due to the discovery of blood groups, he became the Nobel Prize laureate in the field of medicine.

Abstract:
Background: Widal tube agglutination test is a widely used laboratory test for diagnosis of enteric fever especially in resource limited countries where blood culture are not routinely available. We studied the titres from different groups including febrile and healthy populations in order to identify the significant agglutination titre. Materials and Methods: This was a hospital based cross-sectional study. Subjects were divided into three groups: 1) 60 healthy blood samples from volunteer students, 2) 60 febrile non-typhoidal cases and 3) 58 culture positive patient for enteric fever. Results: Among 60 apparently healthy volunteers, agglutination of ≥ 1:20 for anti O and anti-H titres against serotype Typhi were seen in 40 and 46 samples respectively. A significant proportion of sample had a titre of ≥1:80 (n=19) and 1:160 (n=14) for anti O and anti-H titres against serotype Typhi respectively among healthy individuals. Similar observations were seen in febrile non typhoidal cases except for one which had a titre of ≥1:320 for anti O and anti-H titres against serotype Typhi. In blood culture positive typhoid cases, 56 samples showed agglutinations of ≥1:80 for both anti O and anti-H titres against serotype Typhi. However two of the total sample tested showed no agglutinations. In all cases from three groups, anti-H titre for S. enterica serotype Paratyphi A and B were below 1:80. Conclusions: Widal test can be used as presumptive diagnostic tool in all the suspected cases of enteric fever if the titres are specifically raised.Keywords: enteric fever; titre; widal aggultination test.

Abstract:
AbstractPlant lectins are carbohydrate binding proteins or phytohaemagglutinins present in most plants, especially seeds and tubers, which include cereals, potatoes and beans. Lectins have great significance in the diet because of their involvement in gastrointestinal difficulties and erythrocyte agglutination. Blood agglutination activity against A, B, AB and O groups was shown after exposing blood to extracts obtained from 55% of tested plants, while in 45% of plants, agglutination was absent. The results of our study have shown that in humans, 40% of plant extracts exhibited activity against A, 40% of plant extracts exhibited activity against B, and 50% of plant extracts exhibited activity against AB and O groups in humans. The concentration of plant lectins depends on the part of the plant. Lectins from the seeds of certain plants cause the greatest percentage of erythrocyte agglutination, while the lowest agglutination was caused by plant bulbs and leaves. However, lectins derived from all plant species of the family Fabaceae agglutinated erythrocytes of all blood types to some extent.

AbstractObjectives While DNA profiling has become the principal technique for individualization of biological evidences, ABO blood grouping is still a useful test method in the initial stages of crime investigation. Objectives of the study were blood group determination using slide agglutination method, blood group determination from saliva using absorption inhibition method, and comparison of slide agglutination method with that of absorption inhibition method from saliva sample.Materials and Methods A total of 60 subjects were taken randomly with their age ranging from 20 to 60 years. Sixty subjects were divided in to two groups, study group and control group. 5 to 10 mL of unstimulated saliva was collected from 60 patients and Wieners agglutination test was performed to detect the secretor status of blood using absorption inhibition method and compared with that of slide agglutination methodResults Out of 60 subjects, 52 subjects showed secretors of antigen in saliva with percentage value of 86.66% and eight subjects were nonsecretors (13.33%). Slightly higher percentage of secretor status was seen in males 84.6 and 88.2% in females.Conclusion Evaluation of secretor status of blood group antigen from saliva using absorption inhibition method can be useful method in identification of medicolegal cases.

Abstract:
Ruth Ann Sanger's scientific career was concerned with the delineation and mapping of human blood group genes by simple manual methods using, as tools, blood group antibodies and the agglutination reaction followed by statistical analysis of the results. Her active period coincided with the flowering of the whole subject of blood groups, which was initiated by the recognition of the clinical significance of the Rh antigens and the rediscovery of the antiglobulin reaction by Coombs, Mourant and Race (Coombs et al. 1945). In these days of ‘high-technology’ research, it is salutary to recognize that the complex body of knowledge that has been accumulated about blood groups has been derived by using the very simple technique of the visible cross-linking of red cells by antibodies specific for the blood group antigens present on the red cell surface. Landsteiner had by chance discovered the ABO blood group system in 1900 with the use of the agglutination reaction, but little progress was made in the next 45 years and we now know that the main reason for this is that most blood group antibodies are not physically capable of bringing about the cross-linking and agglutination of red cells on their own. This problem was solved by the introduction of the antiglobulin reaction, which uses a secondary antibody to bring about the cross-linking of blood group antibodies already attached to red cells.

Abstract:
Aim. To study the particularities of metabolism associated with AB0 system blood groups by examination of carbohydrate exchange serum parameters. Methods. 446 healthy subjects with different blood groups were examined: 0 (I) blood group - 29.6%, A (II) - 31.8%, B (III) - 24.3%, AB (IV) - 14.3%. The blood group was defined by direct agglutination test in all subjects, piruvate, lactate, glucose, cortisol and insulin serum levels, lactatdehydrogenase and α-аmylase activity was defined using an automatic biochemical analyzer. Results. Group specific features of carbohydrate metabolism in subjects with different blood groups were revealed. In subjects with 0 (I) blood group the lowest glucose and insulin serum levels, the highest amylase activity and piruvate and lactate blood levels were characteristic; in subjects with A (II) blood group - highest level of insulin and cortisol, low lactate levels; in subjects with B (III) blood group - maximal lactatdehydrogenase and minimal amylase activity, high piruvate and lactate blood levels; in subjects with AB (IV) blood group - highest level of glucose, low lactatdehydrogenase and amylase activity, lowest lactate and piruvate blood levels were revealed. Conclusion. The particularities of molecular processes might be associated with blood group and predispose to different health conditions. The features of the metabolic profile of patients with different blood groups are the rationale for individualization of personal standards for each person that might reasonably be considered in clinical practice.

Abstract:
Background: ABO blood group has been associated with various disease phenotypes, particularly cardiovascular disease. Abnormal autonomic response also plays a role in cardiac morbidity. Increasing attention is being focused on the role of autonomic nervous system in health and disease. The literature lacks data on the association of blood groups and cardiac autonomic function. The aim of the study was to find out the association between different blood groups and cardiovascular autonomic functions in young adults.Methods: 150 healthy young students of MMU aged 18-25 years, divided into four groups based on ABO blood grouping, determined by agglutination test (group A, group B, group O and group AB). Various autonomic function tests done were lying to standing test, Valsalva maneuver, Hand grip test (HGT) and Cold pressor test (CPT).Results: The mean baseline heart rate was significantly higher in group O as compared to group A. No parasympathetic alteration between different ABO blood groups was seen. Blood pressure response to HGT and CPT was not statistically significant between different blood groups.Conclusions: Present study revealed no alteration in cardiac autonomic function with regards to ABO blood grouping in young adults.

Abstract:
The western region of Saudi Arabia is known as a multinational region with different ethnic groups of people. This study aims to evaluate the ABO and rhesus blood groups among study subjects in the Western area of Saudi Arabia and their comparison with other regions of the Kingdom. It is a retrospective study. 35,388 participants were included. ABO blood grouping was done using tube method. Agglutination in any tube or hemolysis was considered as positive. Blood grouping was done by a preliminary finger prick, and was repeated again and a serum sample was obtained at the time of donation. Statistical Package for Social Sciences software was used for the data analysis. Results showed that the most common blood group is O, (50.1%) followed by A (29.7%), B (16%) and less frequent is AB (4.1%). Rhesus positive were 91.3%, while rhesus negative were 8.63%. These results demonstrate that the most common blood group in the Western province is O. Blood group A was noticed to be less frequent. Understanding the frequencies of the blood groups and their phenotypes is crucial for blood banking and for setting transfusion service protocols.

Abstract:
Serological discrepancies in matching blood group antigens between donors and patients for blood transfusion may lead to alloimmunisation, especially in multiply transfused patients. Blood group genotyping (BGG) has contributed in reducing this issue. ABO, Fy and Jk antigens are among those to be causative for alloimmunisation through transfusion or pregnancy. The number of alleles of these clinically significant blood groups is ever increasing. Currently, all commercially available high-throughput BGG platforms are only based on pre-defined polymorphisms. Consequently, novel or rare alleles that might have clinical significance are not identified. Next generation sequencing (NGS) circumvents this issue by providing high-throughput comprehensive genotyping of blood group genes in discovery mode to find all existing and novel mutations. Accordingly, a large number of individuals can be genotyped in a single run. Here, we describe an NGS-based method coupled with long-range polymerase chain reaction (LR-PCR) for high-throughput, rapid and extensive genotyping of FY, JK and ABO blood group genes. The Ion Torrent Personal Genome Machine (PGMTM) was used for sequencing the entire FY, JK and ABO blood group genes including flanking regions. Accordingly, high resolution genotyping was obtained. 53 genomic DNA samples were sequenced and genotyped for FY, 67 for JK and 47 for ABO. Sequencing data were aligned to the gene reference sequence derived from the human genome (hg19) to analyse variants. Analysis was accomplished by software packages, such as Ion Torrent SuiteTM plugins. Sanger sequencing of cDNA and cDNA clones was used to confirm findings in the JK gene. The sequencing data had a coverage depth of more than 5000x for FY, 700x for JK and 600x for ABO. NGS data matched with the serological phenotypes of FY alleles FY*A, FY*B and FY*02 Null main polymorphisms, such as FY*A/FY*B (125G > A) in exon 2 and (-67 T > C) in the promotor region. JK variant analysis revealed that the JK*01W.01 allele (130G > A) is common (10/67 samples) with normal antigenicity. The previously described silencing polymorphism (810G > A), leading to a purported JK*B null allele, restores a splice site and does not correlate with loss of Jkb antigenicity (10/67 samples). JK intron analysis revealed several new JK alleles described in this thesis. All 7 exons, introns and the flanking regions of the ABO gene were covered by only four amplicons. Several rare O alleles were found, such as O73 and O75, while one suggested novel O allele was characterised by a missense SNP 482G > A (Arg161His) in exon 7. The ABO reference sequence from hg19 appeared to resemble (O01 and O02) alleles. The intronic SNPs might be used to distinguish between alleles more accurately as a correlation of the intronic SNPs with the alleles was noted for the homozygous O alleles. It is predicted that NGS-based genotyping will replace not only microarray-based genotyping but also serology in the blood group typing of individuals, with great advancements in technology and molecular knowledge being expected in the near future.

Abstract:
Haemagglutination is the recognised serologic technique for common (ABO & Rh) blood group antigen phenotyping with limitations; typing multi-transfused patients and non-invasive foetal blood group determination. Molecular technological advances in characterising the 30 blood group systems have also generated PCR based direct genotyping techniques. Their utility in routine blood banking practice is a rapidly evolving field. The study aims were (1) to establish PCR-SSP assays for KEL, FY and JK blood group genotyping, (2) to evaluate HEA BeadChipTM technology for SNPs detection of RHCc, RHEe, CO, DI, DO, FY, JK, KEL, LU, LW, MNS and SC and haemoglobinopathy S, against serology considering reproducibility, reliability, sensitivity and labour saving potential (3) to evaluate the specificity and sensitivity of TaqMan Real-Time PCR for NIPD of foetal RHD7, RHC, RHc, RHE and SRY status and (4) to establish Real-Time PCR assays and MGB TaqMan probes for 8 sets of gender-independent “Bi-allelic” Short Insertion/Deletion Polymorphisms (SIDPs) as internal assay controls confirming the presence of cell-free foetal DNA (cffDNA). The PCR-SSP results for KEL, FY and JK typing results showed complete concordance with serology for all samples except 1×JKa and 7×Fyb; discrepancies resolved by subsequent DNA sequencing. The HEA BeadChipTM microarray validation on gDNA (n=224) and 22 saliva samples, giving overall allele detection (ADR) and concordance rates (CoR) of >99.8% for the 24 alleles. The Fyx allele (Fyb/Fyx: 265C>T) frequency in Scottish donors (5.4%) was much higher than expected. Saliva-derived gDNA was less sensitive than buffy coat-derived gDNA; ADR 89.9% and 100% respectively. NIPD foetal blood group genotyping by Real-Time PCR of 51 alloimmunised pregnancies (n=104 samples, 12 to ≥40 weeks) with was 100% accurate for RHD7, RHC and RHE assays; 95.7% for RHc and 99% for SRY. The utility of Real-Time TaqMan assays for 8 selected SIDPs as paternal (foetal) markers, were assessed using gDNA, cell-free DNA (cfDNA) from 61 donors and 6 extended families and finally with cffDNA from 13 pregnancies. Based on these research findings, many of the molecular assays are now established in Aberdeen.

Full text
Abstract:
An investigation into the genetic differences in the humoral immune response of swine following vaccination with a sheep red blood cell solution (SRBC) and a commercially prepared Pasteurella multocida (serotype A) bacterin (PmA) was conducted on a total of 268 pigs from two individual trials. This study was also conducted to evaluate the humoral immune response of pigs to a non-pathogen (SPEC) and a known pathogen to swine (PmA). The pigs used in the first trial were from 22 litters born between January 1991 and July 1991. The pigs consisted of Hampshire x Yorkshire (n=114), purebred Yorkshire (n=70) and Hampshire (n=17). Individual pigs were vaccinated at five and eight weeks of age with 2 ml of a 5% SRBC solution and 1 ml of a killed PmA bacterin. AL 11 weeks of age 8 uE of blood was collected frun each animal and serum prepared to determine antibody titer levels against the two antigens by agglutination methods. Pigs utilized in the second study consisted of purebred Duroc (n=11), Haupshire (n= 10), Landrace (n=12) and Yorkshire (n=11) and crossbred Hampshire X Durcc (n= 12) and Yorkshire X Landxace (n=12). Results of trial 1 indicate that breed of pig affected the immune response against both PmA (P<.01) and SRBC (P<.01), with the Hampshire x Yorkshire crossbred pigs having higher titer levels against the PmA than either Hampshire or Yorkshire purebred pigs. The purebred Hampshire were not statistically different from either the purebred Yorkshire or the Hampshire x Yorkshire crossbred pigs in their antibody response to SRBC; however, the Hampshire x Yorkshire crossbred pigs were statistically higher than the Yorkshire pigs. Results from trial 2 indicate highly significant (P<.01) breed differences in the humoral immune response to PmA. Purebred Landrace pigs were superior to both Duroc and Hampshire purebred pigs in their immune response to PmA. Purebred Yorkshire and crossbred Yorkshire X Landrace pigs were superior to purebred Durtcs in their immune response to PmA. NO other significant differences among breeds of pigs occurred in trial 2. A low positive correlation of .22 was found between the pigs' antibody responses to PmA and SRBC in trial 1. Correlation differences among breeds were found between average daily gain while an test and the humoral immune response to both PmA and SRBC. Results suggest that further studies into breed differences of the immune response in swine are warranted. Results also suggest that further studies are needed to evaluate sheep /Ed blood cells as a suitable antigen When conducting research to analyze the humoral immune response in swine.

Abstract:
Measurement of fibrin (ogen) degradation products (FDP) by latex agglutination with polyclonal antifibrinogen may be falsely elevated in liver disease due to the presence of “poorly clottable” fibrinogen in serum (Blood 67:1468, 1986). TSro monoclonal antibodies recognizing different epitopes of fibrin degradation fragment D-dimer (DD) are now commercially available. Because of the reported lack of crossreactivity of the DD monoclonals with fibrinogen, we employed them as tools to distinguish true fibrinolysis from false positive results due to liver disease. 17 citrated plasmas were evaluated by 5%SDS PAGE, nitrocellulose transfer and polyclonal antifibrinogen blotting for detection of FDP (X,ED,Y,D). Samples were then evaluated for ED by latex agglutination and by EIA (enzyme immunoassay) with the following results:Patients in Groups 3a and 3b were jaundiced (bilirubins 3.2-27) and had either hepatitis or cirrhosis except for one patient in Group 3a who had metastatic cancer. Assay for soluble fibrin monomer (SFM) by hemagglutination was negative in group 3b but positive in 5 of 7 patients in group 3a. Neither eta recognized fibrinogen. Purified fibrin monomer gave positive results with both EIAs. Detection of fibrinolysis by latex agglutination using monoclonal anti-DD resolves the problem of false positive results seen with polyclonal antifibrinogen in patients with liver disease. Elevated SFM in the absence of disseminated intravascular coagulation (DIC) in patients with liver disease may induce false positive ED results when measured by EIA.

Abstract:
An original observation of platelet agglutination was found in a 63 y.o. man during 5 years following, without spontaneous bleeding. Low platelet counts (10 × 109/liter) and large agglutinates were observed on blood specimens collected into EDTA (1 to 15 mg/ml whole blood WB), citrate (1/10 volume citrate 0.11 M), sodium heparin (100 units/ml WB), citrate plus acetyl salicylic acid (5 to 100 mg/ml WB), citrate plus prostacyclin (Upjohn 10−5 to 10−6 M)? and buffering anticoagulant (0.8 M citrate, pH 4.65). Low platelet count and large agglutinates were also observed in capillary blood obtained by finger puncture kept at 22° or 37°C. All techniques revealed significant clumping making assessment of overall platelet number impossible. Bleeding time Ivy horizontal incision is longer than 20 minutes.Patient's serum induced normal platelets agglutination up to a 1/512 dilution at 22°and 37°C temperature. Lack of agglutination after treatment of the serum by IgM and indirect immunofluorescence tests identified the IgM nature of the agglutinating factor. This antibody reacted with Glanzmann thrombasthenia platelets ruling out the IIb/IIIa complex as the target of this agglutinin.There was no evidence of platelet activation following agglutination of autologous or alldgenic platelets : electronic microscopy of native blood platelets clumps did not show any sign of activation, and plasma level of B-thromboglobulin was normal in this patient. Normal platelets agglutination by patient's serum was not accompanied with ATP secretion (luciferin-luciferase).This IgM agglutinin was associated with elevation of IgM (700 mg/dl) without clinical or biological signs of auto-immune disease.No similar case with irreversible platelet agglutination in both capillary or venous blood has been reported before. The significance of the observation remains obscure.

Abstract:
Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.
