[Depressive symptoms and insulin pump therapy in people with type 1 diabetes mellitus: A systematic review]

Type 1 Diabetes mellitus (T1DM) is a chronic, multifactorial metabolic disease that requires constant medical care. T1DM is the result of an irreversible destruction of pancreatic β-cells, inevitably leading individuals to chronic exogenous insulin dependence. The prevalence of depression among T1DM is common and affects both the progression and management of the disease. The aim of this study is to present the depressive symptoms in people with T1DM who apply and those who do not apply the insulin pump therapy method and to highlight differences in terms of gender and age. The literature review was conducted using the databases PubMed, Science-Direct and Scopus. The inclusion criteria were the following: the studies had to be conducted in T1DM patients, study depressive symptomatology, the number of participants in the studies to be more than 70 people and to be in English. Initially, 464 articles were retrieved and 11 articles met the requirements for inclusion in the systematic review. The results of the systematic review, excluding paediatric patients with T1DM, showed that patients who apply the insulin pump therapy method were more likely to have higher prevalence and intensity of depressive symptoms, compared to users of multiple daily injections. Respectively, increased depressive symptoms in women with T1DM were presented, regardless of the method of treatment. Factors that mediate this difference in depressive symptoms are the sense of freedom and flexibility in lifestyle, fewer dietary restrictions, the sense of constant "bonding" and social stigma. Finally, mental health professionals should frequently evaluate the depressive symptoms of the T1DM patients, as it has a direct impact on the development and management of the disease.
