A clinical guideline-based management of type 2 diabetes by ayurvedic practitioners in Nepal: A feasibility cluster randomized controlled trial protocol.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is a common chronic condition with significant health and socioeconomic consequences. In Nepal, T2DM is a common disease for which people consult ayurvedic (traditional medical system) practitioners and use ayurvedic medicines. Strong concerns remain about the suboptimal T2DM management of many patients by ayurvedic practitioners, and therefore, based on the best available scientific evidence, we have developed a clinical guideline for managing T2DM by ayurvedic practitioners. The research question to be addressed by a definitive cluster randomized controlled trial (RCT) is whether the introduction of a clinical guideline can improve the management of T2DM by ayurvedic practitioners in Nepal as compared to usual ayurvedic management (i.e., without any clinical guideline). In preparation for this future work, this current study aims to determine the feasibility of undertaking the definitive cluster RCT. METHODS: This is a 2-arm, feasibility cluster RCT with a blinded outcome assessment and a qualitative evaluation. The study is conducted in 12 public and private ayurveda centers in and outside the Kathmandu Valley in Nepal (1:1 intervention:control). Eligible participants should be new T2DM adult patients (i.e., treatment naïve) - the glycated hemoglobin level should be 6.5% or above but less than 9%. At least 120 participants (60/group) will be recruited and followed up for 6 months. Important parameters, needed to design the definitive trial, will be estimated, such as the standard deviation of the outcome measure (i.e., glycated hemoglobin level at 6-month follow-up), intraclass correlation coefficient, cluster size, recruitment, the time needed to recruit participants, follow-up, and adherence to the recommended ayurvedic medicine. Semi-structured qualitative interviews will be conducted with around 20 to 30 participants and all the participating ayurvedic practitioners to explore their experiences and perspectives of taking part in the study and of the intervention and a sample of eligible people declining to participate in the study to explore the reasons behind nonparticipation. DISCUSSION: We are now conducting a feasibility cluster RCT in Nepal to determine the feasibility of undertaking the definitive cluster trial. The first participant was recruited on 17 July 2022. If the feasibility is promising (such as recruitment, follow-up, and adherence to the recommended ayurvedic medicine), then the parameters estimated will be used to design the definitive cluster trial. Decisions over whether to modify the protocol will mainly be informed by the qualitative data.

Effectiveness and Safety of Ayurvedic Medicines in Type 2 Diabetes Mellitus Management: A Systematic Review and Meta-Analysis.

Introduction: Many Ayurvedic medicines have the potential for managing type 2 diabetes mellitus (T2DM), with previous systematic reviews demonstrating effectiveness and safety for specific Ayurvedic medicines. However, many of the reviews need updating and none provide a comprehensive summary of all the Ayurvedic medicines evaluated for managing T2DM. Objective: The objective of this systematic review was to evaluate and synthesize evidence on the effectiveness and safety of Ayurvedic medicines for managing T2DM. Inclusion criteria: Published and unpublished RCTs assessing the effectiveness and safety of Ayurvedic medicines for managing T2DM in adults. Methods: The JBI systematic review methodology was followed. A comprehensive search of sources (including 18 electronic databases) from inception to 16 January 2021 was made. No language restrictions were applied. Data synthesis was conducted using narrative synthesis and random effects meta-analyses, where appropriate. Pooled results are reported as mean differences (MD) with 95% confidence intervals (CI). Results: Out of 32,519 records identified from the searches, 219 articles were included in the systematic review representing 199 RCTs (21,191 participants) of 98 Ayurvedic medicines. Overall, in the studies reviewed the methodology was not adequately reported, resulting in poorer methodological quality scoring. Glycated hemoglobin (HbA1c) was reduced using Aegle marmelos (L.) Corrêa (MD -1.6%; 95% CI -3 to -0.3), Boswellia serrata Roxb. (-0.5; -0.7 to -0.4), Gynostemma pentaphyllum (Thunb.) Makino (-1; -1.5 to -0.6), Momordica charantia L. (-0.3; -0.4 to -0.1), Nigella sativa L. (-0.4; -0.6 to -0.1), Plantago ovata Forssk. (-0.9; -1.4 to -0.3), Tinospora cordifolia (Willd.) Hook.f. and Thomson (-0.5; -0.6 to -0.5), Trigonella foenum-graecum L. (-0.6; -0.9 to -0.4), and Urtica dioica L. (-1.3; -2.4 to -0.2) compared to control. Similarly, fasting blood glucose (FBG) was reduced by 4-56 mg/dl for a range of Ayurvedic medicines. Very few studies assessed health-related quality of life (HRQoL). Adverse events were not reported in many studies, and if reported, these were mostly none to mild and predominately related to the gastrointestinal tract. Conclusion: The current evidence suggests the benefit of a range of Ayurvedic medicines in improving glycemic control in T2DM patients. Given the limitations of the available evidence and to strengthen the evidence base, high-quality RCTs should be conducted and reported.

Effectiveness and safety of Ayurvedic medicines in type 2 diabetes mellitus management: a systematic review protocol.

OBJECTIVE: The objective of this review is to evaluate and synthesize evidence on the effectiveness and safety of Ayurvedic medicines for managing type 2 diabetes mellitus. INTRODUCTION: Several randomized controlled trials have been conducted to assess the effectiveness and safety of Ayurvedic medicines for managing type 2 diabetes. Systematic reviews have been conducted on this topic but need to be updated. The findings from this review will be used to develop a clinical guideline for managing type 2 diabetes by Ayurvedic practitioners in India. INCLUSION CRITERIA: Randomized controlled trials assessing the effectiveness and safety of Ayurvedic medicines for managing type 2 diabetes in adults will be included in this systematic review. METHODS: The authors will search for a wide range of sources to find both published and unpublished studies, including, but not limited to, MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Allied and Complementary Medicine Database (Ovid). No language restrictions will be applied. The JBI systematic review methodology will be followed when conducting the review. Data synthesis will be conducted using narrative synthesis and meta-analyses, where appropriate. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42018118285.
