Abstract
Aims Our study aimed to evaluate the association between the erythropoietin gene rs1617640 polymorphism and diabetic retinopathy (DR) in diabetes patients.
Methods In this preliminary retrospective study the genotyping was performed on 860 DNA samples from Caucasian patients with type 2 diabetes mellitus (T2DM). For analyzing the effect of the polymorphism, patients were assigned into three phenotypic subgroups: non-DR (without retinopathy), NPDR (with non-proliferative diabetic retinopathy) and PDR (with proliferative diabetic retinopathy). The rs1617640 polymorphism was analyzed using polymerase chain reaction (PCR)–restriction fragment length polymorphism (RFLP) and direct DNA sequencing procedures.
Results A statistically significant difference in the polymorphism distribution was observed between T2DM patients with DR (both NPDR and PDR) and those without DR. The minor G allele was associated with the increased risk of DR. In the NPDR subgroup subjects carrying the G allele had 1.53-fold higher risk of developing retinopathy. Similarly, in the PDR subgroup patients carrying the G allele showed almost twofold increased risk of PDR in a dominant model of inheritance.
Conclusion Our results demonstrate that in T2DM patients the EPO rs1617460 polymorphism is associated with signifi-cantly increased risk of developing DR. This finding can provide a new insight into the role of EPO gene in the pathophysi-ology of microvascular complications of diabetes.

Background Pain may be absent in a substantial proportion of elderly patients with acute abdominal conditions. This study explored the association between type 2 diabetes mellitus (T2DM) and asymptomatic presentation.
Methods We conducted a cross-sectional analysis of 215 patients aged≥65 years admitted with acute abdominal conditions. Demographic, clinical, and laboratory data were extracted from medical records. Descriptive statistics and multivariable logistic regression were used to identify associative predictors of asymptomatic acute abdomen (AAA).
Results The median age was 82 years [77–86]; 54.4% (n=117) were female; 31.2% (n=67) had T2DM. Overall, 33.5% (n=72) presented without abdominal pain. T2DM prevalence was higher in AAA than symptomatic patients (44.4% vs. 24.5%, p<0.01). In multivariable analysis, T2DM (OR 1.95, 95% CI 1.10–3.45, p=0.02), lower heart rate (OR 0.83, 95% CI 0.71–0.96, p=0.01), and absence of fever (OR 0.50, 95% CI 0.26–0.95, p=0.03) were associated with AAA. Among patients with T2DM, longer diabetes duration (12.5 years [10.5–14.5] vs. 8.8 years [5.0–11.0]; p<0.01) and higher HbA1c (8.2% [7.2–8.7] vs. 7.5% [6.8–7.6]; p=0.02) were associated with asymptomatic presentation.
Conclusions Asymptomatic acute abdomen is common among elderly patients. Long-standing and poorly controlled T2DM is associated with absent pain. Prospective studies are needed to clarify causal mechanisms, and early glyco-metabolic assessment may aid recognition of at-risk patients.
