Abstract
Objective: Preclinical data suggest nitazoxanide (NTZ) as a potential PPAR-γ agonist with potential benefits in type 2 diabetes. This pilot trial aimed to explore the tolerability and preliminary effects of NTZ as an add-on therapy to the existing metformin-vildagliptin combination on glycemic control and inflammatory biomarkers in type 2 diabetes patients.
Methods: Eighty-eight patients were analyzed in the control and NTZ groups (44 per group). All patients were treated with metformin-vildagliptin combination. The NTZ group received 500 mg nitazoxanide orally twice daily. The primary outcome was glycemic control, assessed by glycated hemoglobin (HbA1c) and fasting blood glucose. Secondary outcomes included fasting insulin, serum interleukin-6 (IL-6), high mobility group box 1 (HMGB-1), asprosin, and malondialdehyde (MDA). All outcomes were measured at baseline and after three months.
Results: A between-groups comparison revealed significantly lower inflammatory markers with NTZ compared to control [IL-6: 23.64 ng/L (21.00-32.71) vs. 32.52 ng/L (29.63-36.13) and HMGB-1: 10.46 ng/mL (6.37-14.61) vs. 22.60 ng/mL (20.18-27.37), P < 0.001 for both]. HbA1c, fasting blood glucose, insulin, asprosin, and MDA were not considerably different between the two groups. Markedly lower levels of IL-6 (P = 0.009), HMGB-1 (P < 0.001), asprosin, (P = 0.002), and MDA (P < 0.001) were observed following NTZ treatment. Conversely, IL-6 and HMGB-1 increased significantly in the control group (P < 0.001 for both). Other biomarkers did not change significantly in both groups.
Conclusion: NTZ may alleviate oxidative stress and inflammation in type 2 diabetes despite no improvement in glycemic parameters.
Trial registration: This trial is registered on ClinicalTrials.gov under the name: Nitazoxanide as Adjuvant Therapy in Type 2 Diabetes Mellitus with the identifier: NCT06010992. Registration date: 8-2023.
期刊介绍:
Well-established as a major journal in today’s rapidly advancing experimental and clinical research areas, Endocrine publishes original articles devoted to basic (including molecular, cellular and physiological studies), translational and clinical research in all the different fields of endocrinology and metabolism. Articles will be accepted based on peer-reviews, priority, and editorial decision. Invited reviews, mini-reviews and viewpoints on relevant pathophysiological and clinical topics, as well as Editorials on articles appearing in the Journal, are published. Unsolicited Editorials will be evaluated by the editorial team. Outcomes of scientific meetings, as well as guidelines and position statements, may be submitted. The Journal also considers special feature articles in the field of endocrine genetics and epigenetics, as well as articles devoted to novel methods and techniques in endocrinology.
Endocrine covers controversial, clinical endocrine issues. Meta-analyses on endocrine and metabolic topics are also accepted. Descriptions of single clinical cases and/or small patients studies are not published unless of exceptional interest. However, reports of novel imaging studies and endocrine side effects in single patients may be considered. Research letters and letters to the editor related or unrelated to recently published articles can be submitted.
Endocrine covers leading topics in endocrinology such as neuroendocrinology, pituitary and hypothalamic peptides, thyroid physiological and clinical aspects, bone and mineral metabolism and osteoporosis, obesity, lipid and energy metabolism and food intake control, insulin, Type 1 and Type 2 diabetes, hormones of male and female reproduction, adrenal diseases pediatric and geriatric endocrinology, endocrine hypertension and endocrine oncology.
