Diabetic retinopathy: variations in patient therapeutic outcomes and pharmacogenomics.

ABSTRACT: Diabetes and its microvascular complications in patients poses a significant challenge and constitutes a major health problem. When it comes to manifestations in the eye, each case of diabetic retinopathy (DR) is unique, in terms of the phenotype, genotype, and, more importantly, the therapeutic response. It is therefore important to identify factors that distinguish one patient from another. Personalized therapy in DR is a new trend aimed at achieving maximum therapeutic response in patients by identifying genotypic and phenotypic factors that may result in less than optimal response to conventional therapy, and consequently, lead to poorer outcome. With advances in the identification of these genetic markers, such as gene polymorphisms and human leucocyte antigen associations, as well as development of drugs that can target their effects, the future of personalized medicine in DR is promising. In this comprehensive review, data from various studies have been analyzed to present what has been achieved in the field of pharmacogenomics thus far. An insight into future research is also provided.

Project description:IntroductionFew qualitative studies have explored the patient experience of daily life with proliferative diabetic retinopathy (PDR) and associated treatments. Herein, a conceptual model was developed to comprehensively examine symptoms, functional impacts, and treatment experiences in PDR.MethodsA qualitative, mixed-methods study comprising a literature search and semi-structured interviews with clinicians and patients was conducted. Published literature and online patient resources were searched to identify concepts relevant to patients, including symptoms, functional impacts, and treatment experiences of PDR. Semi-structured interviews with experienced clinicians were conducted to identify symptoms and impacts reported by patients with PDR and to receive feedback regarding concepts identified from the literature search. A preliminary conceptual model was then developed based on findings from the literature search and clinician interviews. Patients with PDR participated in two rounds of semi-structured interviews to identify additional concepts relevant to the patient experience in PDR and associated treatments, which informed revisions to the conceptual model. Saturation of patient interviews was assessed.ResultsFindings from the literature search and clinician interviews yielded 109 concepts that were included in a preliminary conceptual model with three overarching domains: symptoms, impacts, and managing the disease. Clinicians confirmed concepts identified from the literature search. During interviews, patients reported a broad spectrum of symptoms (e.g., red vision); functional impacts relating to activities of daily living (e.g., reading), emotional functioning (e.g., loss of independence), and social functioning (e.g., problems recognizing faces); and treatment experiences (e.g., improves eye problems, no change) associated with PDR. Additional concepts elicited in patient interviews informed revisions to the conceptual model. Saturation was achieved in the patient sample.ConclusionsA wide variety of symptoms, functional impacts, and treatment experiences that significantly affect health-related quality of life were identified in patients with PDR. These insights are critical for understanding PDR symptomology and assessing treatment response.
