Urinary tract infection is the most common adult bacterial infection worldwide. Antigens of ABO and Lewis blood groups may influence bacterial adherence and lead to an increase in the frequency of urinary tract infections in adults. This study aimed to evaluate the relationship of ABO and Lewis blood groups with urinary tract infections.

In this experimental study, a blood sample of 80 urinary tract infection patients from AL-Sader Teaching Hospital, Iraq, and 50 healthy persons was used for the determination of ABO and Lewis blood groups by agglutination assay. Urine samples of urinary tract infection patients were cultured and identified based on culture characteristics, gram staining, and biochemical tests.

Urinary tract infection was significantly higher in patients with the O blood group (42.5%) and the Lewis (a-b-) phenotype (38.8%) than in patients with other blood groups and the control group. Escherichia coli was the most common bacterial isolate observed in urinary tract infection patients. Also, E. coli was significantly higher in the UTI patients with the O blood group and the Lewis (a-b-) phenotype.

People of the O blood group and the Lewis (a-b-) phenotype are more susceptible to urinary tract infections. Escherichia coli is the main cause of urinary tract infections.

 Colorectal cancer (CC) is one of the most important causes of death due to cancer in the world. The association of blood groups with CC in many races has been reported in previous studies. So far, no study has evaluated the relationship between blood group type, tumor location, and polyp type.

 This study aimed at evaluating the association of the ABO blood group and CC, tumor location, and polyp type.

 In this case-control study, 802 subjects (401 cases and 401 controls), who underwent surgery at our medical centers between 2014 and 2021, were included. The case group was selected from the hospital records of patients with CC, and the controls were selected from non-cancer patients who were admitted to the same centers for reasons other than cancer. Patients’ demographic characteristics and clinical and pathology findings were extracted from the medical profile, and blood group information was extracted from the blood bank. Multivariate logistic regression analysis was used for the predictive variables of CC.

 The risk of CC in patients with blood type A was significantly higher than non-A. While the risk of developing CC in patients with blood type O was significantly lower than non-O O. The risk of developing neoplastic polyps was significantly higher in patients with blood type A compared to non-A. The results of multivariate analysis showed that ABO blood type A (OR Adju: 1.66) and O (OR Adju: 0.78) and neoplastic polyp type (OR Adju: 1.36) were associated with CC.

 The results of this study showed that ABO blood group type was significantly related to CC and polyp type.

The rapid spread of the virus around the world is raising alarms among scientists to identify vulnerable people who are at greater risk of infection. In this regard, the present study aimed to determine the prevalence of severe acute respiratory syndrome coronavirus 2 in different blood groups.

To find relevant studies, a comprehensive and systematic search was conducted based on the PRISMA guidelines in international databases such as PubMed, Scopus, Web of Sciences, and Google Scholar by December 31, 2020.

After the audit and exclusion of double and unrelated studies, 19 articles were included in the analysis. The most prevalent blood types in alive patients were A and O which calculated the aggregate prevalence at - 39.06 (95% CI: 36.22-41.94) and 35.60 (95% CI: 32.48-38.79). In addition, patients with blood groups B and AB were less than two other groups. The aggregated/estimated prevalence was 7.72 (95% CI: 5.06-10.88) and 16.23 (95% CI: 12.86-19.91) for AB and B, respectively. The results for the deceased had a similar pattern that was high for blood types A and O.

The current meta-analysis validated different prevalence rates of blood group types in patients with COVID-19, confirming that types A and O blood groups are the most prevalent types of deaths and live patients.

Systemic lupus erythematous (SLE) and rheumatoid arthritis (RA) are autoimmune diseases in which the antigen-antibody system plays an important role. As blood group and Rh are determined by the presence or absence of antigens on the surface of red blood cells (RBCs), we aimed to determine the distribution of ABO and Rh blood groups in SLE and RA patients and its association with disease manifestations.

This short communication is based on a study that was conducted on 434 SLE and 828 RA patients. We evaluated the distribution of ABO and Rh blood groups in RA and SLE patients.

This study projected that in lupus patients, Coombs-positive autoimmune hemolytic anemia and arthritis were more common among the B blood type and Rh-positive group, respectively. Furthermore, there was no relation between ABO and Rh blood group and rheumatoid factor (RF) and anti-Cyclic Citrullinated Peptide (anti-CCP) seropositivity. Moreover, there was no difference in distribution of blood groups in RA and SLE patients.

The higher frequency of blood group B in hemolytic anemia, and positive Rh in arthritis in lupus patients, develop the hypothesis of probable role of ABO blood group antigen in some manifestations of lupus.

The ABO blood group antigens have been associated with coronary artery disease (CAD) and cardiovascular mortality. However, there are some controversies in this regard. We sought to determine the association between the ABO blood group and the severity of CAD among patients undergoing elective diagnostic coronary angiography (CAG).

In this retrospective study, patients undergoing elective CAG were recruited during a year, from January to December 2019. The diagnosis of CAD was based on the narrowing of coronary artery lumen (<50% as mild CAD, 50-70% as moderate CAD, and >70% as severe CAD). Subsequently, the number of involved coronary arteries was also defined. The ABO blood group and Rh status were also identified.

A total of 192 patients undergoing elective CAG were assessed. The patients’ mean age was 59.6 ± 10.7 years, and 113 (58.9%) subjects were male. After categorization into the O and the non-O blood groups, the number of involved coronary arteries and the severity of lumen narrowing were not significantly different between groups. Those values were also comparable between the A, B, AB, and O blood groups. Irrespective of blood group, patients with negative Rh had a higher prevalence of coronary artery narrowing (50-70%) compared to patients with positive Rh (p=0.043).

This study showed no association between the ABO blood group and the severity of CAD among patients undergoing elective CAG. Moreover, negative Rh was associated with the lower degrees of coronary artery narrowing compared to positive Rh.

There is paucity of data about the possible role of ABO antigen in response to pharmacologic reperfusion therapy in ST-segment elevation myocardial infarction (STEMI) and its relationship with ST segment recovery; thus, we aimed to evaluate the association of ABO antigen with ST-segment resolution in STEMI patients treated with thrombolysis.

This prospective and observational study was conducted between March 2016 and September 2017 on patients with first acute STEMI within the first 12 hours after onset of symptoms treated with thrombolysis. Myocardial reperfusion success was determined by single-lead ST-segment recovery in 12-lead ECG. Patients were considered as responders if ST-segment resolved ≥50% or were assigned as non-responders if ST-segment resolution was <50%. Univariable and multivariable analyses were performed to examine the contribution of “A” and “B” blood group antigens to ST-segment resolution and the occurrence of major adverse cardiovascular or cerebrovascular event (MACCE). Odds ratio (OR) with 95% confidence interval (CI) were reported for each variable.

In this study 303 patients (187 males and 116 females) with a mean age of 56.6 ± 16.8 (ranging from 39 to 87 years) were enrolled. 184 patients (60.7%) were responders and 119 patients (39.2%) were non-responders. The presence of either A (4.5 folds increase) or B (5.4 folds increase) antigen was associated with a higher likelihood of a response to thrombolytic therapy, while had not effect on the occurrence of MACCE.

We conclude that the presence of A or B blood group antigens is associated with a better response to thrombolytic therapy in patients with acute STEMI. This finding may imply a higher likelihood for thrombotic occlusion of coronary arteries in patients who have either A or B antigen in their blood.

Several studies have found that certain diseases are associated with ABO blood groups. The aim of the present study was to investigate the correlation of ABO Rh blood group with dental malocclusion in the population of Mysuru.

In this study patients of 15–28 years of age will be selected, irrespective of gender from the hospital, Mysuru. It is an observational study with a duration of 3–4months. A total of 278 subjects between the age group of 15-28 years who visited the JSS hospital, Mysuru were recruited for this study. The maxillary and mandibular molar relation of teeth in maximum intercuspation using Angle’s classification were recorded. Blood group was evaluated using the ABO blood grouping system. Mean, Standard deviation, frequency, percentage were used for descriptive statistics. Chi-square test was used for inferential statistics. Statistical Package of Social Science (SPSS), version 16 was used for statistical
analysis.

Out of 278 people ‘O’ blood group was found to be most commonly associated with Angle’s Class I malocclusion (71.3%). Class II div I and div II was found to be more common in ‘A’ blood group (42.68%) and (4.9%) respectively. Class III being most common in ‘B’ blood group (6.5%).

A significant correlation exists between blood group and malocclusion. The prevalence of malocclusions being highest in blood group O, followed by A, B and AB in Mysuru. Class II div I malocclusion was more prevalent in ‘A’ followed by ‘B’ blood group.

Lichen planus (LP) is a skin disease with unknown origin; however, some studies revealed that ABO blood group is correlated with LP; the current study aimed at evaluating this possible relationship.

The current case-control study was conducted on 79 patients with LP referring to Shohada-e-Tajrish and Loghman-e-Hakim hospitals as well as 79 healthy donors as the control group.

The most common type of LP was cutaneous phenotype (57 out of 79); in the patients group, the frequency of ABO blood groups was A (38%), O (36.7%), B (16.5%) and AB (8.9%), while it was O (34.2%), A (27.8%), B (26.6%), and AB (11.4%) in the control group. Blood group A observed more frequently in patients with mucosal phenotype (P = 0.012), but the correlation between LP and Rh was not significant (P = 0.3).

The results of the current study revealed that Rh has no impacts on LP. Based on the current study findings, individuals with blood group A were more susceptible to mucosal phenotype of LP
