Type 1 Diabetes in Pregnancy: A Review of Complications and Management

Pregnancy complications and autoimmune diseases in women: systematic review and meta-analysis

BACKGROUND

Pregnancy complications might lead to the development of autoimmune diseases in women. This review aims to summarise studies evaluating the association between pregnancy complications and the development of autoimmune diseases in women.

METHODS

Medline, CINAHL, and Cochrane databases were searched up to January 2024. Nineteen pregnancy complications and 15 autoimmune conditions were included. Title, abstract, full-text screening, data extraction, and quality assessment were performed by two reviewers independently. Data were synthesised using narrative and quantitative methods. Results were presented using odds ratios (OR), relative risks (RR), incidence rate ratios (IRR), and 95% confidence intervals (CI).

RESULTS

Thirty studies were included. One study reported composite exposure to pregnancy complications had a risk of any autoimmune disease RR 3.20 (2.90-3.51) compared to women without pregnancy complications. Women with hyperemesis gravidarum had a higher risk of developing coeliac disease (n = 1) IRR 1.98 (1.27-2.94), Crohn's disease (n = 1) IRR 1.61 (1.25-2.04), psoriasis (n = 1) IRR 1.33 (1.01-1.71), and rheumatoid arthritis (n = 2) IRR 1.35 (1.09-1.64). Miscarriage associated with subsequent diagnosis of Sjogren syndrome (n = 2) IRR 1.33 (1.06-2.81) and rheumatoid arthritis (n = 4) OR 1.11 (1.04-1.20). Gestational hypertension/preeclampsia was linked with the development of systemic sclerosis (n = 2) IRR 2.60 (1.10-4.60) and T1DM (n = 2) IRR 2.37 (2.09-2.68). Stillbirth associated with composite autoimmune conditions (n = 2) RR 5.82 (95% CI 4.87-6.81) and aIRR 1.25 (1.12-1.40). Postpartum psychosis was associated with autoimmune thyroid disease (n = 1) aIRR2.26 (1.61-2.90).

CONCLUSIONS

Women with pregnancy complications subsequently had a higher risk of being diagnosed with autoimmune conditions. Whether this is due to pre-existing undiagnosed health conditions or being causally linked to pregnancy complications is not known.

Financial stress in emerging adults with type 1 diabetes: a mini review integrating lessons from cancer research

Amongst adults in the United States, those ages 18-30 have the highest unemployment rates, the lowest incomes, and are the most likely to be uninsured. Achieving financial independence is a core developmental task for this age group, but for those with type 1 diabetes (T1D), the high costs of insulin and diabetes supplies as well as an employment-based insurance model with minimal safety net can make this a formidable challenge. Cost-related non-adherence to diabetes management is particularly high in emerging adults with T1D and is associated with severe consequences, such as diabetic ketoacidosis (DKA) and even death. Objective financial burden and subjective financial distress related to illness are not unique to diabetes; in cancer care this construct is termed financial toxicity. Researchers have identified that emerging adults with cancer are particularly vulnerable to financial toxicity. Such research has helped inform models of care for cancer patients to mitigate cost-related stress. This mini review aims to briefly describe the state of the science on financial stress for emerging adults with T1D and explore parallels in cancer scholarship that can help guide future work in diabetes care to reduce health inequity, drive research forward, improve clinical care, and inform policy debates.
