Background
Therapeutic goals have been established to decrease the risk of long-term complications of type 1 diabetes (T1DM). The effects of these guidelines should be constantly evaluated. Hence, the present study examines the frequency at which children with T1DM treated by one of the Polish reference centers complied with the therapeutic targets issued in 2014 by the International Society for Pediatric and Adolescent Diabetes (ISPAD) and by the Diabetes Poland (PTD).
Methods
A retrospective analysis (years 2011–2014) was performed in patients with T1DM aged 6.5–18 years, with diabetes duration >12 months and no change of insulin regimen within 6 months. Collected data included insulin therapy regimen, weight, height, blood pressure, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG) and glycated hemoglobin (HbA1c) level from the last hospitalization.
Results
The records of 447 patients (260 boys, 299 treated with insulin pump) were analyzed. All ISPAD goals were achieved by 123 (27.5%) patients, but only 43 (9.6%) met all PTD targets. Optimal HbA1c was achieved by 224 (50.1%) according to ISPAD criteria (HbA1c<7.5%) and by 87 (19.6%) patients according to PTD (HbA1c≤6.5%). Obesity was diagnosed in 11.6% of the patients; 19.7% of the patients were overweight. In logistic regression, patient age was the only independent predictor of failing to achieve complete T1DM control (p=0.001, OR=1.12 [1.05–1.23]) and optimal HbA1c (p=0.01, OR=1.1 [1.0–1.2]) according to ISPAD guidelines. Moreover, girls had a greater risk of failing body mass index (BMI) targets (PTD: p=0.002, OR=2.16; ISPAD: p=0.0001, OR=3.37) and LDL-C targets (p=0.005, OR=1.8) than boys.
Conclusions
Overall, control of vascular risk factors in Polish children with T1DM is unsatisfactory. While too few children are achieving the HbA1c target set by PTD, it is possible that such strict national target helps half of the Polish school-age patients achieve ISPAD-issued aim which is more liberal. High prevalence of overweight among children with T1DM warrants initiatives focused not only on glycemic control but also on motivation of patients to lead a healthy lifestyle.
Diclofenac belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs), which are amongst the most frequently prescribed drugs to treat fever, pain and inflammation. Despite the presence of NSAIDs on the pharmaceutical market for several decades, epidemiological studies have shown new clinical applications of NSAIDs, and new mechanisms of their action were discovered. The unfolded protein response (UPR) activated under endoplasmic reticulum (ER) stress is involved in the pathophysiology of many diseases and may become a drug target, therefore, the study evaluated the effects of diclofenac on the tunicamycin-induced UPR pathways in endothelial cells. RT PCR analysis showed that diclofenac significantly inhibited activation of ER stress-responsive genes, i.e., CHOP/DITT3, GRP78/HSPA5 and DNAJB9. Additionally, the drug diminished the significant upregulation and release of the GRP78 protein, as evaluated using the ELISA assay, which was likely to be involved in the mechanism of the UPR activation resulting in apoptosis induction in endothelial cells. These results suggest the value of diclofenac as a factor capable of restoring the ER homeostasis in endothelial cells by diminishing the UPR.
Patients with T1D and psoriasis present higher endogenous insulin secretion at T1D onset and a tendency for better glycemic control during the first 6 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
