Study Notes

Medical Nutrition Therapy for Pulmonary Disease

Based on Krause's Food and the Nutrition Care Process, Chapter 33
FNES 366 Medical Nutrition Therapy, Allison Charny, MSEd, RDN, CDCES, CDN

Anatomy of the Pulmonary System

The respiratory system includes upper and lower respiratory tracts.
The upper respiratory tract involves the nasal cavity, nares, pharynx, and larynx.
The lower respiratory tract includes the trachea, bronchi bronchioles, lobes of lungs and diaphragm.
The alveoli and capillaries are the functional components of respiration where gas exchange occurs.
The alveoli have a thin epithelial wall, surrounded by capillaries where oxygen and carbon dioxide exchange.

Gas Exchange in the Pulmonary System

Gas exchange, through ventilation in the lungs takes place primarily in the alveoli
Oxygen from the alveoli is transferred to the blood and carried to tissues.
Carbon dioxide from the blood is released into the alveoli and breathed out.
The processes of gas exchange are critical for maintaining cellular function throughout the body.

Nutrition and Lung Immune Defense Mechanisms

The respiratory system has defense mechanisms to filter and remove foreign matter.
Structures like cilia and mucus help move contaminants out of the lungs.
Lung immune responses include macrophages that protect against pathogens within the lungs.

Alveolar Macrophages and Systemic Immune Response

Alveolar macrophages are important in lung health.
These cells engulf and destroy foreign particles and pathogens within the alveoli
They play a role in protecting against infections and irritants in the lungs.

Functions of the Lungs

The lungs contribute to acid-base balance within the body.
The lungs play a role in the synthesis of arachidonic acid, which has various functions in the body.
ACE converts angiotensin I to angiotensin II, regulating blood pressure and other bodily functions.

Nutrition and the Pulmonary System

Malnutrition negatively impacts pulmonary function.
Malnutrition can impair lung structure, elasticity and function, respiratory muscle strength, and lung immune defense.
Pulmonary disease often increases energy requirements and can cause weight loss, thereby affecting overall health.
Patients often struggle to consume enough nutrients if they experience complications from pulmonary disease or treatment.

Selected Pulmonary Conditions with Nutritional Implications

A variety of pulmonary diseases, categorized as neonatal, obstructive, tumor, infection, primary and secondary, acute, and chronic conditions, have nutritional implications.
Examples include bronchopulmonary dysplasia, chronic lung disease of prematurity, cystic fibrosis, chronic obstructive pulmonary disease (COPD) including Emphysema and chronic bronchitis, asthma, lung cancer, pneumonia, tuberculosis, and others.

Adverse Effects of Lung Disease on Nutritional Status

Respiratory illnesses can increase energy expenditure due to the increased work of breathing.
Patients with lung diseases may have reduced intake due to fluid restrictions, shortness of breath, anorexia, gastrointestinal distress, or difficulty preparing food.
Extra limitations include fatigue, financial resources, feeding issues (in infants, children), altered metabolism, or medication-food interactions.

Cystic Fibrosis

Inherited autosomal recessive disorder affecting chloride, sodium, and bicarbonate transport.
Epithelial cells and exocrine glands secrete thick mucus, impacting the respiratory, sweat, intestinal, pancreatic, liver, and reproductive tracts.
Neonatal screening aids in preventing malnutrition in affected infants.
"Classic" presentation is characterized by a high chloride concentration in sweat.

Pathophysiology of Cystic Fibrosis

Pulmonary and sinus disease, pancreatic disease (including pancreatic insufficiency, pancreatitis, and CF-related diabetes), bone disease, and various other complications further contribute to the multiple system dysfunction often seen in cystic fibrosis.

Medical Management of Cystic Fibrosis

Multidisciplinary management focused on respiratory and gastrointestinal systems
Pharmaceutical intervention includes Ivacaftor to restore gene function and treatment for recurrent respiratory infections.
Pancreatic enzyme replacement therapy (PERT) is also employed, along with managing intestinal and hepatobiliary concerns (including, but not limited to malabsorption, and glucose regulation).

Medical Nutrition Therapy in Cystic Fibrosis

Individualized calorie recommendations based on BMI are important.
Fat-soluble vitamins (A, D, E, K) and salt are often supplemented due to potential deficiencies.
Enzyme therapy is individualized depending on the level of pancreatic insufficiency and consumed food.
Overnight enteral feedings are commonly used to ensure adequate calorie and nutrient intake.

Asthma

A complex interaction between environmental exposures and genetics.
Inflammation and swelling in the airways, leading to smooth muscle tightening in smaller airways.
Characterized by airflow obstruction, both allergic and nonallergic.

Medical Management for Asthma

Routine monitoring of symptoms and lung function,
Patient education,
Control of environmental triggers,
Pharmacotherapy.

Medical Nutrition Therapy for Asthma

Addressing dietary triggers including gastroesophageal reflux disease (GERD) and food allergens (e.g., sulfites) is critical.
Educating patients about personalized diets with optimal nutrient levels is important.
Monitoring growth in children, monitoring food-drug interactions (e.g., with steroids), and recognizing a potential link between high BMI and asthma are further important aspects.
Anti-inflammatory diet may also aid in symptom management.

Chronic Obstructive Pulmonary Disease (COPD)

Obstruction of airways includes destruction of lung parenchyma (reducing elastic recoil) and productive cough with bronchi inflammation
Often caused by tobacco smoking,
Environmental air pollution and genetics.

Medical Management of COPD

Assessing and monitoring ongoing COPD,
Reducing risk factors (smoking cessation),
Managing stable COPD (using bronchodilators, steroids, and oxygen)
Managing complications (like respiratory failure, pneumonia, CHF, or narcotics)
Implementing treatment plans such as pulmonary rehabilitation programs, supplemental oxygen, medications, and surgery (as indicated).

Nutritional Assessment for Adults with COPD

A comprehensive approach to nutritional assessment involves historical details about medical and nutrition history, and weight measurement.
Essential measurements include assessment of the respiratory status, oxygen saturation, dental conditions, senses of smell and taste, and further assessing gastrointestinal function.

Nutritional Assessment for Adults with COPD (Continued)

Nutritional evaluation should include anthropometric measures (e.g., weight, height, and skinfold measurements, NFPE measurements).
Hemoglobin, hematocrit, serum electrolytes, serum proteins, and further additional biochemical tests may also be necessary.

MNT for COPD

Malnutrition is prevalent in COPD patients.
Individualized energy and macronutrient needs are essential, ensuring adequate intake without overfeeding.
Macronutrient recommendations include protein (1.2 to 1.5 g/kg), and a balanced distribution of protein (15-20% of total calories), fat (30-45% of total calories), and carbohydrates (40-55% of total calories).

MNT for COPD (Continued)

Individualized vitamin and mineral supplementation (considering vitamins and minerals like Vitamin C, Magnesium, Calcium, and potential Vit D and K requirements as needed)
Addressing fluid and sodium needs (e.g., 30-35 mL/kg of fluid for cor pulmonale, as well as potential potassium requirements as needed).
Identifying iron deficiency anemia, an often overlooked concern in COPD patients, and managing it accordingly.
Individualized feeding strategies are often necessary and may include enteral feedings as appropriate given the particular needs of the individual patient

Pulmonary Hypertension

High blood pressure in the pulmonary circulation, leading to progressive shortness of breath, hypoxia, and right ventricular enlargement or hypertrophy.
Classified into 5 categories based on their underlying causes, requiring personalized medical management accordingly.
Nutrition therapy is often individualized based on the underlying cause of the pulmonary hypertension, and may include sodium, fluid, or intake restrictions

Parenchymal Lung Disease PLD

Also known as interstitial lung disease (ILD).
A primary or secondary condition characterized by progressive shortness of breath and hypoxia, associated with progressive lung scarring.
Conditions that increase risks may include smoking, exposure to metals, organic dusts, or other environmental factors.

Tuberculosis

Multidrug-resistant tuberculosis (MDR-TB) is important to consider as it may increase complications
Patients may have high energy and fluid requirements, while also needing careful attention to medication timing to maximize absorption.
Food-nutrient interactions and appropriate timing of intake are crucial to prevent nutritional deficiencies.

Lung Cancer

Detection through X-ray is sometimes possible in asymptomatic individuals.
Common symptoms include cough and shortness of breath.
Pulmonary cachexia syndrome, characterized by low BMI, is a concern.
Patients also face side effects from treatments like radiation therapy, chemotherapy, or surgery.

Obesity Hypoventilation Syndrome (OHS)

OHS includes obesity and increased arterial carbon dioxide level (>45 mm Hg).
Increased work of breathing may contribute
Individuals with OHS may also have obstructive sleep apnea.
Medical management frequently involves CPAP (Continuous Positive Airway Pressure).

Pleural Effusion

Fluid accumulation in the pleural space due to conditions such as heart failure, liver diseases, kidney diseases, infection, cancer, or autoimmune disorders.
Medical management typically includes fluid drainage and treatment of underlying causes.
Nutrition therapy is individualized based on the underlying cause of the pleural effusion and malnutrition, including patients with congestive heart failure (CHF).

Chylothorax

Pleural effusion caused by disruption or obstruction of the thoracic duct (leakage of chyle from the intestinal system).
Leakage of chyle is common in cases of surgical trauma, sarcoidosis, or idiopathic conditions.
Very high pleural triglyceride levels (>110 mg/dL) are often observed.
Nutrition therapy typically includes a long-chain fatty acid-restricted diet and medium-chain triglyceride (MCT) supplements..

Acute Respiratory Distress Syndrome (ARDS)

Diffuse alveolar damage characterized by respiratory failure, severe hypoxia.
Common causes include sepsis, trauma or aspiration events, and or pneumonia.
Malnutrition is a frequent concern in patients requiring mechanical ventilation.
Complications are common, stemming from both underfeeding and overfeeding.

Aspiration

Movement of food or fluids into the lungs, potentiality causing potentially fatal complications including pneumonia.
Positioning appropriately during eating is crucial.
Risk is higher in infants, toddlers, older adults, and patients with neurological or other complications such as gastrointestinal (GI) issues.
Liquids, round foods, and large food chunks are particularly risky.

Pneumonia

Commonly caused by infection or aspiration.
Patients that require mechanical ventilation are at higher risk for Ventilator-associated pneumonia (VAP).
Risk of conditions that predispose a patient to pneumonia are to be noted

Covid-19

A coronavirus causing severe acute respiratory syndrome (SARS).
Symptoms can range from mild cold-like symptoms to severe acute respiratory distress syndrome (ARDS)
Obesity is identified as a key risk factor for poor outcome, though less common in some patient populations (e.g., China).
Various onset patterns have been observed, including acute respiratory failure, and hospitalization requiring advanced medical treatment.
