Outcomes

Primary Outcomes

Evaluate specific symptoms of neuropathic pain in diabetic subjects

Evaluate the effectiveness of Cronilief™ supplementation versus placebo, in combination with standard therapy, in improving specific symptoms of neuropathic pain in diabetic subjects after 8 weeks of supplementation, using the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) questionnaire as an assessment tool. The LANSS score ranges from 0 to 24, with higher scores indicating a greater neuropathic pain component (worse outcome). A score ≥12 is indicative of neuropathic pain.

Time frame: Baseline (T0), 4 week (T1), 8 week (T2) and one month after the end of integration

Secondary Outcomes

Evaluate sleep quality

Assess the impact of Cronilief™ supplementation on sleep quality, measured using the Pittsburgh Sleep Quality Index (PSQI). The PSQI total score ranges from 0 to 21, with higher scores indicating worse sleep quality (poorer outcome). A total score \>5 is indicative of poor sleep quality.

Time frame: Baseline (T0), 4 week (T1), 8 week (T2) and one month after the end of integration

Evaluate emotional states

Assess the impact of Cronilief™ supplementation on emotional states related to stress, anxiety and depression through the administration of the Depression Anxiety Stress Scales (DASS-21). The DASS-21 consists of three subscales (Depression, Anxiety, Stress), each ranging from 0 to 21. Higher scores indicate greater severity of symptoms (worse outcome).

Time frame: Baseline (T0), 4 week (T1), 8 week (T2) and one month after the end of integration

Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)

Assess the safety of Cronilief™ by monitoring AEs (Adverse Events) and SAEs (Serious Adverse Events) evaluated by investigators and reported in accordance with current regulations.

Time frame: Baseline (T0), 4 week (T1), 8 week (T2) and one month after the end of integration
