Associations between seroprevalence of Helicobacter pylori and ABO/rhesus blood group antigens in healthy blood donors in southwest Iran

Objective To investigate correlations between ABO/rhesus (Rh) blood group antigens and anti- Helicobacter pylori and anti-cytotoxin-associated gene A (CagA) seropositivity in blood donors. Methods A total of 311 blood donors were enrolled. ABO and Rh blood groups were determined using hemagglutination tests. Specific anti- H. pylori IgG and anti-CagA IgG antibodies in sera were quantitated by enzyme-linked immunosorbent assay. Correlations between blood groups and anti- H. pylori and anti-CagA seropositivity were evaluated using the Chi-square test. Results O+ was the most frequent blood type (38%, n = 118). Anti- H. pylori IgG seropositivity was observed in 240 (77.2%) blood donors, while anti-CagA IgG seropositivity was observed in 132 (42.5%) blood donors. Although seropositivity rates for both anti- H. pylori and anti-CagA IgG were higher in individuals with blood type O, no statistically significant associations were observed between seropositivity and any ABO/Rh blood groups. Conclusion Individuals with blood type O may have higher rates of H. pylori seropositivity.

“…There have been few studies on the relationship between the Rh blood group system and infectious diseases. Even though previous studies have reported the relationship of the Rh blood group with the novel coronavirus disease (COVID- 19), parvovirus infection, leptospirosis, HIV, and hepatitis B [3][4][5][6][7][8]. The study showed that individuals with Rh+ were at higher risk of COVID-19 infection, while individuals with Rh− were at a lower Trop.…”

“…In addition to COVID-19, parvovirus B19 viraemia has been reported to be associated with Rh+ donations, suggesting a protective factor in donors who lack this antigen [5]. There was a report about the increased prevalence of the severe form of leptospirosis in people with the Rh blood group, though there was no statistically significant difference between the severity of the disease and Rh [6]. The previous study also reported that children who were Rh− were at higher risk of HIV-1 infection than children who were Rh+, suggesting that Rh blood groups may be markers for genetic susceptibility to vertical HIV infection [7].…”

Association between Rhesus Blood Groups and Malaria Infection: A Systematic Review and Meta-Analysis

et al. 2023

In the literature, there was inconsistency in the risk of malaria between individuals with Rhesus blood group positive (Rh+) and negative (Rh−). The systematic review aimed to investigate the risk of malaria among participants with different Rh blood types. All observational studies that reported the occurrence of Plasmodium infection and investigation of the Rh blood group were searched in five databases (Scopus, EMBASE, MEDLINE, PubMed, and Ovid). Strengthening the Reporting of Observational Studies in Epidemiology was used to assess the reporting quality in the included studies. A random-effects model was used to calculate the pooled log odds ratio and 95% confidence intervals (CIs). Database searches yielded a total of 879 articles, of which 36 were eligible for inclusion in the systematic review. The majority of the included studies (44.4%) revealed that Rh+ individuals had a lower proportion of malaria than Rh− individuals; however, the remaining studies revealed a higher or no difference in the proportion of malaria between Rh+ and Rh− individuals. Overall, with moderate heterogeneity, the pooled results showed no difference in malaria risk between patients with Rh+ and Rh− (p = 0.85, pooled log odds-ratio: 0.02, 95% CI: −0.20–0.25, I2: 65.1%, 32 studies). The current study found no link between the Rh blood group and malaria, even though there was a moderate amount of heterogeneity. Further studies using prospective designs and a definitive method for Plasmodium identification are needed to investigate the risk of Plasmodium infection in Rh+ individuals and increase the reliability and quality of these studies.

“…This disease occurs in both temperate and tropical regions. The incidence in the tropics is almost 10 times higher than that of the temperate regions [ 1 , 2 ]. Leptospirosis is a rare disease that is rarely reported, and there are no reliable statistics on its global incidence.…”

Background Limited studies have been conducted on patients with renal function recovery regarding severe leptospirosis. The purpose of this study is to evaluate the effectiveness of N-acetylcysteine (NAC) in accelerating the reduction of serum creatinine in patients with leptospirosis. Patients and methods This is a clinical trial study involving 64 patients with leptospirosis, with microscopic agglutination tests used to confirm the diagnosis of acute kidney injury. NAC was given to patients with a glomerular filtration rate of less than 60 ml/min at 1200 mg every 12 h, and it lasted for 48 h. Next, 32 patients were measured and the relationship between the length of hospitalization, age, and sex was also examined. Additionally, the two groups of case and control were compared in terms of the rate of decrease in serum creatinine level in three different time periods. The Shapro-Wilk test was used to investigate the distribution of data. Results No significant differences were observed in the decrease in serum creatinine level on the first, third, and seventh days of hospitalization and also in the use of NAC between the case and control groups (P = 0.255). In addition, the use of NAC had no significant effect on reducing the length of hospitalization (P = 0.067). Conclusion Recovery of acute kidney injury following leptospirosis and drugs that accelerate the healing process in these patients require further studies with greater sample size and longer follow-up time.
