Expanding the use of patient-reported outcomes (PROs): Screening youth with type 1 diabetes from underrepresented populations

AIM

Youth from lower socioeconomic status (SES) have suboptimal type 1 diabetes (T1D) outcomes. Patient reported outcomes (PROs) measure psychosocial states and are associated with T1D outcomes, however are understudied in low SES youth. We aimed to evaluate associations between PROs and public insurance status, a proxy for low SES.

METHODS

We analyzed survey data from 129 youth with T1D (age 15.7 ± 2.3 years, 33 % publicly insured) screened with PROMIS Global Health (PGH, measuring global health) and Patient Health Questionnaire (PHQ-9, measuring depressive symptoms) during diabetes appointments. Correlation and regression analyses evaluated differences in PGH and PHQ-9 by insurance status.

RESULTS

For youth with public insurance, lower global health correlated with lower self-monitoring blood glucose (SMBG; r = 0.38,p = 0.033) and older age (r = -0.45,p = 0.005). In youth with private insurance, lower global health correlated with lower SMBG (r = 0.27,p = 0.018) and female sex (rho = 0.26,p = 0.015). For youth with private insurance, higher depressive symptoms correlated with higher body mass index (r = 0.22,p = 0.03) and fewer SMBG (r = -0.35,p = 0.04). In multivariate regression analyses, public insurance was inversely associated with global health (p = 0.027).

CONCLUSION

PGH is a particularly salient PRO in youth with public insurance. Global health may be an important psychosocial factor to assess in youth with T1D from low SES backgrounds.

Screening of key pathogenic genes of type 1 diabetes in children

Background

The etiology of type 1 diabetes mellitus (T1DM) in pediatric populations remains poorly understood. The key to precise prevention and treatment of T1DM in identifying crucial pathogenic genes. These key pathogenic genes can serve as biological markers for early diagnosis and classification, as well as therapeutic targets. However, there is currently a lack of relevant research on screening key pathogenic genes based on sequencing data and efficient algorithms.

Methods

The transcriptome sequencing results of peripheral blood mononuclear cells (PBMCs) of children with T1DM (GSE156035) were downloaded from the Gene Expression Omnibus (GEO) database. The data set contained 20 T1DM samples and 20 control samples. Differentially expressed genes (DEGs) in children with T1DM were selected based on fold change (FC) >1.5 times and adjusted P value <0.05. The weighted gene co-expression network was constructed. Hub genes were screened as modular membership (MM) >0.8 and gene significance (GS) >0.5. Intersection genes of DEGs and hub genes were defined as key pathogenic genes. The diagnostic efficacy of key pathogenic genes was evaluated using receiver operator characteristic (ROC) curves.

Results

A total of 293 DEGs were selected. Compared with the control group, 94 genes were down-regulated and 199 genes were up-regulated in the treatment group. Black modules (Cor =0.52, P=2e-12) were positively correlated with diabetic traits, whereas brown modules (Cor =-0.51, P=5e-12) and pink modules (Cor =-0.53, P=5e-13) were negatively correlated with diabetic traits. The black module contained 15 hub genes, the pink gene module contained 9 hub genes, and the brown module contained 52 hub genes. The intersection of hub genes and DEGs contained 2 genes, CCL25 and EGFR. The expression of CCL25 and EGFR was low in control samples and high in the test group (P<0.001). The areas under ROC curves (AUCs) of CCL25 and EGFR were 0.852 and 0.867, respectively (P<0.05).

Conclusions

Weighted correlation network analysis (WGCNA) was used to identify the key pathogenic genes of T1DM in children, including CCL25 and EGFR, which have good diagnostic efficacy for T1DM in children.

Mediating Effects of Technology-Based Therapy on the Relationship Between Socioeconomic Status and Glycemic Management in Pediatric Type 1 Diabetes

Background: Socioeconomic disparities exist related to accessibility and uptake of diabetes technologies that impact glycemic management. The aims of this study were to describe diabetes technology use (continuous subcutaneous insulin infusion [CSII] and continuous glucose monitoring [CGM]) in children with type 1 diabetes (T1D) and assess the mediating effects of each technology on the relationship between socioeconomic status (SES) and glycemic management. Methods: Single-center retrospective cross-sectional study of children aged 0-18 years (n = 813) with T1D and valid postal codes between 2018 and 2020. Extracted data were linked to validated census-based material deprivation (MD) quintiles. Exposures included MD and technology use (CSII, CGM), whereas the primary outcome was glycemic management (HbA1c). Results: Of 813 patients included, 379 (46.6%) and 246 (30.3%) individuals used CGM and CSII, respectively. Real-time CGM (rtCGM) and CSII were associated with both MD and HbA1c, but intermittently scanned CGM (isCGM) was not. There was a difference in HbA1c of +1.17% between patients from the most (Q5) and least deprived (Q1) MD quintile (P < 0.0001), and significant mediating effects for rtCGM and CSII use, but not isCGM. rtCGM use and CSII use accounted for 0.14% (P < 0.0001) and 0.25% (P < 0.0001) of the difference in HbA1c between patients from Q1 and Q5 quintiles (indirect effects), representing 12.0% and 23.1% of this difference, respectively. Conclusions: CSII and rtCGM use partially mediated the significant discrepancies observed with SES and glycemic management, highlighting potential benefits of broader access to these technologies to improve diabetes outcomes and help mitigate the negative impact of deprivation on diabetes management.

Increase in the Diagnosis and Severity of Presentation of Pediatric Type 1 and Type 2 Diabetes during the COVID-19 Pandemic

INTRODUCTION

The impact of the COVID-19 pandemic on the incidence of pediatric type 1 (T1D) and type 2 diabetes (T2D) and severity of presentation at diagnosis is unclear.

METHODS

A retrospective comparison of 737 youth diagnosed with T1D and T2D during the initial 12 months of the COVID-19 pandemic and in the preceding 2 years was conducted at a pediatric tertiary care center.

RESULTS

Incident cases of T1D rose from 152 to 158 in the 2 years before the pandemic (3.9% increase) to 182 cases during the pandemic (15.2% increase). The prevalence of diabetic ketoacidosis (DKA) at T1D diagnosis increased over 3 years (41.4%, 51.9%, and 57.7%, p = 0.003); severe DKA increased during the pandemic as compared to the 2 years before (16.8% vs. 28%, p = 0.004). Although there was no difference in the mean hemoglobin A1c (HbA1c) between racial and ethnic groups at T1D diagnosis in the 2-years pre-pandemic (p = 0.31), during the pandemic HbA1c at T1D diagnosis was higher in non-Hispanic Black (NHB) youth (11.3 ± 1.4%, non-Hispanic White 10.5 ± 1.6%, Latinx 10.8 ± 1.5%, p = 0.01). Incident cases of T2D decreased from 54 to 50 cases (7.4% decrease) over the 2-years pre-pandemic and increased 182% during the pandemic (n = 141, 1.45 cases/month, p < 0.001). As compared to the 2-years pre-pandemic, cases increased most among NHB youth (56.7% vs. 76.6%, p = 0.001) and males (40.4% vs. 58.9%, p = 0.005). Cases of DKA (5.8% vs. 23.4%, p < 0.001) and hyperosmolar DKA (0 vs. 9.2%, p = 0.001) increased among youth with T2D during the pandemic.

CONCLUSIONS

During the pandemic, the incidence and severity of presentation of T1D increased modestly, while incident cases of T2D increased 182%, with a nearly 6-fold increase in DKA and nearly a 10% incidence of hyperosmolar DKA. NHB youth were disproportionately impacted, raising concern about worsening of pre-existing health disparities during and after the pandemic.

Care of Pediatric Patients with Diabetes During the Coronavirus Disease 2019 (COVID-19) Pandemic

This article summarizes clinical observations and management strategies in pediatric type 1 diabetes (T1D) during the coronavirus disease 2019 (COVID-19) pandemic. Despite initial fears that children with diabetes would, similar to adults with diabetes, be at risk for severe COVID-19, most pediatric patients with a history of T1D who developed COVID-19 had mild disease or were asymptomatic similar to their peers without diabetes. The article also summarizes the use of telemedicine to provide ongoing care for pediatric patients with T1D during the COVID-19 pandemic. Finally, the article highlights important lessons learned about management of pediatric diabetes during the COVID-19 pandemic.

Effectiveness and equity of continuous subcutaneous insulin infusions in pediatric type 1 diabetes: A systematic review and meta-analysis of the literature

AIMS

We conducted a systematic review and meta-analysis of randomized controlled trials (RCT) and non-randomized studies (NRS) to assess the effectiveness and equity of continuous subcutaneous insulin infusions (CSII) versus multiple-daily injections (MDI) on glycemic outcomes.

METHODS

Searches were conducted between 2000 and 2019 in MEDLINE, CENTRAL, EMBASE and HTA. Included studies compared the CSII vs MDI in children and young people (CYP) ≤ 20 years with type 1 diabetes. Two independent reviewers screened the articles, extracted the data, assessed the risk of bias, evaluated the quality of evidence, and identified equity data. Results were pooled with a random-effects model.

RESULTS

Of the 578 articles screened, 16 RCT (545 CYP on CSII) and 70 NRS (73253 on CSII) were included in the meta-analysis. There was moderate-level evidence that the CSII lower HbA_1c in RCT (pooled mean difference [MD]: -0.22%; 95% confidence interval [CI]: -0.33, -0.11%; I²:34%) and insufficient in NRS (pooled MD: -0.45%; 95%CI: -0.52, -0.38%; I²:99%). The pooled incidence rate ratio of severe hypoglycemia on CSII vs MDI in RCT was 0.87 (95%CI: 0.55, 1.37; I²:0%; low-level evidence), and 0.71 (95%CI: 0.63, 0.81; I²:57%, insufficient evidence) in NRS. Health-related quality of life presented insufficient evidence. Equity data were scarcely reported.

CONCLUSIONS

CSII modestly lower HbA_1c when compared with MDI. Current literature does not provide adequate data on other glycemic outcomes. Future assessment on diabetes technology should include individual and area-level socioeconomic data. The study protocol was pre-registered in PROSPERO (CRD42018116474).

The Role of Socioeconomic Status in Latino Health Disparities Among Youth with Type 1 Diabetes: a Systematic Review

PURPOSE OF REVIEW

Type 1 diabetes (T1D) incidence is growing faster among Latino than non-Latino White youth, but ethnic disparities in self-management behaviors and HbA1c are unclear. Socioeconomic status (SES) is a key factor in T1D, which may confound or contribute to disparities in Latino pediatric T1D management. A systematic review examined whether ethnic differences in pediatric T1D outcomes occur and are independent of socioeconomic status (SES).

RECENT FINDINGS

Latino youth displayed lower self-management and higher HbA1c in approximately half of the identified studies prior to including SES in analyses. Ethnic differences in self-management were found for objective (i.e., frequency of blood glucose checks), but not subjective measures. Ethnic differences were often eliminated when SES was statistically controlled. SES moderated some differences, suggesting complex sociocultural processes. Articles varied widely in SES measures and the analytic methods used to evaluate ethnic disparities. Pediatric Latino T1D disparities are inconsistent and at least partially dependent on the SES context. Recommendations for future research to systematically evaluate SES and Latino T1D disparities are made.

The Role of Parent Self-Regulation in Youth Type 1 Diabetes Management

PURPOSE OF REVIEW

Youth with strong self-regulation (SR), or the ability to manage thoughts, emotions, and behaviors, engage in more effective type 1 diabetes (T1D) management. However, while parent support and engagement are critical to ensuring positive youth T1D outcomes, it is rarely considered that parents' SR may also influence youth T1D management. If this is the case, novel interventions to improve parents' SR or ensure adequate support for parents with SR challenges offer great potential to improve family functioning and youth T1D management.

RECENT FINDINGS

Theoretical and preliminary empirical evidence suggests that parental SR impacts family processes that support youth T1D treatment regimen adherence. Furthermore, parent and youth SR likely interact, with high parent SR enhancing the positive effects of high youth SR or compensating for low youth SR. Continued research is needed to better understand the ways in which parent SR matters to youth T1D management and identify how to support improvements in T1D management among families of parents with low SR.

Home Visits for Children and Adolescents with Uncontrolled Type 1 Diabetes

Background: Home-based video visits were provided over one year as a supplement to in-person care for pediatric type 1 diabetes (T1D) patients with suboptimal glycemic control. We hypothesized that the intervention would be feasible and satisfactory for the target population and would significantly improve hemoglobin A1c (HbA1c) levels and completion of recommended quarterly diabetes clinic visits. Methods: This was a nonrandomized clinical trial. Fifty-seven patients aged 3-17 years with known T1D and HbA1c ≥8% (64 mmol/mol) were recruited to receive the intervention. The study population was 49% adolescent (13-17 years old) and 58% publicly insured patients. Video visits were scheduled every 4, 6, or 8 weeks depending on the HbA1c level. HbA1c levels as well as frequencies of clinic visits and of diabetes-related emergency department (ED) and hospital encounters were compared before and after the study. Results: Thirty participants completed 12 months of video visits. The study cohort demonstrated significant improvement in mean HbA1c in both intention-to-treat (N = 57) analysis (10.8% [95 mmol/mol] to 10.0% [86 mmol/mol], P = 0.01) and per-protocol (N = 30) analysis (10.8% [95 mmol/mol] to 9.6% [81 mmol/mol], P = 0.004). Completion of ≥4 annual diabetes clinic visits improved significantly from 21% at baseline to 83% during the study period for the entire cohort, P < 0.0001. The frequency of diabetes-related ED and hospital encounters did not change significantly. Conclusions: Home-based video visits are a feasible supplement to in-person care for children and adolescents with T1D and suboptimal glycemic control and can successfully improve HbA1c levels and adherence to recommended frequency of care in this high-risk clinical population.

The early natural history of albuminuria in young adults with youth-onset type 1 and type 2 diabetes

AIMS

To determine among adolescents and young adults with youth-onset type 1 diabetes and type 2 diabetes the rates and risk factors for albuminuria regression and progression.

METHODS

Data from SEARCH, a longitudinal observational study of youth-onset type 1 diabetes (N = 1316) and type 2 diabetes (N = 143) were analyzed. Urine albumin:creatinine ratio (UACR) was measured from random urine specimens at baseline and follow-up visits (mean 7 years later). Albuminuria regression was defined as halving of baseline UACR when baseline UACR was ≥30 μg/mg; progression was defined as doubling of baseline UACR when follow-up UACR was ≥30 μg/mg, respectively. Multivariable regression assessed risk factors associated with low-risk albuminuria category (combined persistently-low albuminuria and regression) versus moderate-risk albuminuria category (combined persistently-high albuminuria and progression).

RESULTS

Albuminuria progression was more common in type 2 diabetes versus type 1 diabetes (15.4% versus 6.0%, p<0.001). Moderate-risk albuminuria was associated with increasing HbA1c (adjusted OR (aOR) = 1.3, 95% CI 1.1-1.6) and lack of private health insurance (aOR = 2.7, 95%CI 1.1-6.5) in type 1 diabetes; and African American race (OR = 4.6, 95% CI 1.2-14.2), lower estimated insulin sensitivity score (aOR = 2.1, 95% CI 1.4-3.3), baseline UACR (aOR = 3.2, 95% CI 1.7-5.8), and follow-up estimated glomerular filtration rate (eGFR) (10-unit increase aOR = 1.3, 95% CI 1.0, 1.5) in type 2 diabetes.

CONCLUSIONS

In the first decade of diabetes duration, kidney complications in type 2 diabetes are significantly more aggressive than in type 1 diabetes and may be associated with less modifiable risk factors including race, insulin sensitivity, and eGFR. Early interventions may help reduce long-term kidney complications.

Long-term impact of childhood-onset type 1 diabetes on social life, quality of life and sexuality

AIM

This study describes the socio-professional outcomes, health-related quality of life (HRQOL) and sexuality of adults with childhood-onset type 1 diabetes (T1D).

METHODS

The study participants (n=388), recruited from a nationwide registry (age: 28.5 ± 3.1 years; T1D duration: 17.0 ± 2.7 years), completed a questionnaire (198 items); the results were compared with the French general population using standardized incidence ratios (SIRs) and Z scores matched for age, gender and period with/without education levels and patterns of family life. Linear regression models also investigated correlates of SF-36 Physical (PCS) and Mental Composite Scores (MCS).

RESULTS

Compared with the French general population, education levels of people with T1D were similar, with 68.6% having at least a high-school diploma or higher (SIR: 1.06, 95% CI: 0.93; 1.20), as were also their patterns of family life. Unemployment was higher in T1D women (15.3%, SIR: 1.50, 1.00; 2.05), but not in T1D men (8.6%, SIR: 0.96, 0.51; 1.57). Social discrimination was more common (SIR: 5.64, 4.64; 6.62), and frequency of daily alcohol consumption was higher (SIR: men, 3.34, 2.38; 4.54; women, 6.53, 4.57; 12.99). PCS and MCS were decreased moderately (mean ± SD: 52.0 ± 7.5; mean Z score: -0.2, 95% CI: -0.3; -0.1) and substantially (mean ± SD: 42.1 ± 12.4; mean Z score: -0.7, -0.8; -0.6), respectively. Fatigue and abandoning sports were predictive of a lower HRQOL. Both men and women were more frequently dissatisfied with their sex life. Prevalence of sexual problems was higher in women (SIR for: dysorgasmia, 1.91, 1.21-2.88; decreased/loss of desire: 2.11, 1.35-3.08), but similar in men. Participants with T1D-related complications had preserved social outcomes, but altered HRQOL.

CONCLUSION

Young adults with T1D have satisfactory social participation. However, their higher alcohol consumption, lower MCS and frequent dissatisfaction with sexuality suggest a heavy impact of the disease on morale, especially in women. Improving the everyday well-being of these young adults represents a key challenge for diabetes healthcare.
