Pulmonary cachexia, observed in individuals with chronic obstructive pulmonary disease (COPD) is a multifactorial syndrome characterized by disruptions in energy metabolism, increased protein degradation, and an impaired capacity to preserve muscle mass. These metabolic disturbances not only exacerbate the underlying respiratory condition but also significantly contribute to elevated mortality rates among affected individuals. Current therapeutic strategies for managing cachexia primarily emphasize pharmacological treatments, nutritional interventions, and multimodal approaches. Among the nutritional interventions, various supplements have shown potential in mitigating the catabolic processes associated with cachexia. Notably, supplementation with n-3 polyunsaturated fatty acids (n-3 PUFAs) and vitamin D has emerged as a promising intervention, likely due to their involvement in key pathological mechanisms underlying the disease. While previous studies have investigated the combined effects of these supplements through oral nutritional supplementation, this study aims to evaluate and compare the clinical effectiveness of n-3 PUFAs and vitamin D as distinct therapeutic interventions for managing pulmonary cachexia.

Change in Body Mass Index (BMI)
Change in BMI from baseline (pre-intervention), measured using a calibrated weight and height scale, and expressed in kg/m².
Time frame: Baseline and Week 6
Fat-Free Mass Index (FFMI)
Change in FFMI from baseline (pre-intervention), measured using bioelectrical impedance analysis, and expressed in kg/m².
Time frame: Baseline and week 6
Fat Mass Index (FMI)
Change in FFM from baseline (pre-intervention), measured using bioelectrical impedance analysis, and expressed in kg/m².
Time frame: Baseline and week 6
Handgrip Strength (HGS)
Change from baseline HGS measured in kilograms using a calibrated dynamometer.
Time frame: Baseline and week 6
Mid-Arm Muscle Circumference (MAMC)
Change in MAMC from baseline (pre-intervention), calculated using the formula: MAMC = Mid-Arm Circumference (MAC) - (π × Triceps Skinfold (TSF)), expressed in centimeters (cm). The Mid-Arm Circumference (MAC) is measured using a flexible tape measure at the midpoint of the upper arm, and Triceps Skinfold (TSF) is measured using skinfold caliper.
Time frame: Baseline and week 6
Simplified Nutritional Appetite Questionnaire (SNAQ) - Anorexia
Change in SNAQ score from baseline (pre-intervention). SNAQ is a brief, four-item screening tool used to assess anorexia with a score of 14 or below indicates poor appetite.
Time frame: Baseline and week 6
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F)
Change in FACIT-F score from baseline (pre-intervention). FACIT-F is a 13-item scale used to assess the severity of fatigue in patients with chronic illnesses, with a scale range of 0 to 52. Higher scores indicate less fatigue (better functional status), while lower scores indicate more severe fatigue (worse functional status).
Time frame: Baseline and week 6
Edmonton Symptom Assessment System (ESAS) - Symptom Burden
Change in ESAS score from baseline (pre-intervention). ESAS is a multi-item scale used to assess symptom burden in patients. The scale ranges from 0 to 100, with higher scores indicating greater symptom severity and lower scores indicating less severe symptoms
Time frame: Baseline and week 6
Medication Adherence
Percentage of patients achieving medication adherence of 80% or more, as assessed through pill count.
Time frame: Week 6
Adverse Effects
Percentage of patients experiencing adverse effects, assessed throughout the study.
Time frame: Eight weeks
