Kwashiorkor and Marasmus

Introduction – Kwashiorkor and Marasmus

Kwashiorkor and Marasmus are two forms of severe malnutrition that commonly affect children in developing countries. They are both caused by a lack of sufficient dietary protein and calories, but they have distinct clinical features and different underlying causes.

Kwashiorkor typically occurs in children between 18 months and 3 years of age who have been weaned from breastfeeding and are introduced to a diet low in protein. The condition is characterized by edema (swelling) of the legs, feet, and face, as well as hair and skin changes, a distended abdomen, and muscle wasting.

Marasmus, on the other hand, is a severe form of malnutrition that results from a chronic deficiency of both protein and calories. It is characterized by severe wasting of muscle and fat tissue, with the child having a very thin and emaciated appearance. Unlike kwashiorkor, there is no edema or swelling associated with marasmus.

Both conditions are associated with high rates of morbidity and mortality, and they often occur together in children who are severely malnourished. The treatment for both conditions involves nutritional rehabilitation with a high-protein, high-calorie diet and close monitoring for potential complications. In severe cases, hospitalization and intensive medical support may be necessary to stabilize the child’s condition.

Kwashiorkor

  • Causes
    • protein-deficient diet
  • Presentation
    • skin lesions
    • pitting edema
      • ↓ albumin leads to ↓ oncotic pressure in vasculature and loss of fluid into extravascular space
    • ascites
    • liver malfunction
      • ↓ apolipoprotein synthesis
      • fatty liver
    • defects in cell-mediated immunity
      • ↓ in complement protein synthesis
  • muscle protein relatively unchanged

SymptomsKwashiorkor

  • Edema: This is the hallmark symptom of kwashiorkor. The child’s face, feet, and legs may become swollen due to fluid accumulation.
  • Changes in skin and hair: The skin may become dry, scaly, and discolored, with patches of lighter or darker skin. The hair may become thin, brittle, and discolored as well.
  • Fatigue and weakness: The child may feel weak and lethargic due to the body’s inability to produce enough energy.
  • Loss of muscle mass: There may be a loss of muscle mass, particularly in the arms and legs.
  • Poor growth: The child’s growth may be stunted, and they may have delayed development.
  • Distended abdomen: The abdomen may become distended due to fluid accumulation and liver enlargement.
  • Irritability: The child may be irritable and have a reduced appetite.

Studies – Kwashiorkor

  • Studies on the role of inflammation: Research has suggested that inflammation plays a key role in the development of kwashiorkor. Inflammation can cause the body to break down muscle tissue and can also impair the absorption of nutrients from the diet.
  • Studies on the use of amino acid supplements: Amino acid supplements have been shown to be effective in treating kwashiorkor, particularly when combined with a high-calorie diet. These supplements can help to restore the body’s levels of essential amino acids, which are necessary for the growth and repair of tissues.
  • Studies on the long-term effects of kwashiorkor: Kwashiorkor can have long-term effects on a child’s health and development, even after treatment. Research has shown that children who have suffered from kwashiorkor may be at increased risk of chronic diseases such as diabetes and hypertension later in life.
  • Studies on the social and environmental factors that contribute to kwashiorkor: Poverty, food insecurity, and lack of access to clean water and sanitation are all factors that can contribute to the development of kwashiorkor. Research has shown that addressing these underlying factors is essential for preventing and treating the condition.

Marasmus

  • Causes
    • protein- and caloric-deficient diet
  • Presentation
    • tissue and muscle wasting
      • “broomstick” extremities
      • breakdown of muscle protein for energy
    • loss of subcutaneous fat
  • variable edema

Symptoms – Marasmus

  1. Severe wasting: The child may appear emaciated, with little or no body fat or muscle mass. The skin may appear loose and saggy.
  2. Growth retardation: The child’s growth may be stunted, and they may be much smaller than other children their age.
  3. Chronic diarrhea: The child may have frequent episodes of diarrhea, which can further exacerbate malnutrition.
  4. Weakness and fatigue: The child may feel weak and lethargic due to the body’s inability to produce enough energy.
  5. Irritability and apathy: The child may be irritable or apathetic, with a reduced appetite.
  6. Changes in skin and hair: The skin may become dry, scaly, and discolored, with patches of lighter or darker skin. The hair may become thin, brittle, and discolored as well.

Studies – Marasmus

  • The impact of malnutrition on immune function: Malnutrition, including marasmus, can impair the immune system, leaving individuals more susceptible to infections. Research has shown that malnutrition can lead to changes in immune function, including alterations in immune cell populations and reduced antibody production.
  • Nutritional interventions: Studies have investigated the effectiveness of various nutritional interventions in the treatment of marasmus. These interventions may include therapeutic feeding programs, nutrient supplements, and fortified foods. Some studies have found that providing a combination of protein and energy in the diet is particularly effective in treating marasmus.
  • Long-term outcomes: Marasmus can have long-term effects on an individual’s health and development, even after treatment. Research has shown that individuals who have suffered from marasmus may be at increased risk of chronic diseases such as diabetes and hypertension later in life.

Treatment – Kwashiorkor and Marasmus

  • Nutritional rehabilitation: The first step in treating kwashiorkor is to provide the child with a high-calorie, high-protein diet. This is usually done using specially formulated therapeutic foods that are designed to meet the child’s nutritional needs. In some cases, a feeding tube or intravenous fluids may be necessary to provide adequate nutrition.
  • Medical monitoring: Children with kwashiorkor are at risk of developing complications such as infections, anemia, and electrolyte imbalances. Medical monitoring is essential to ensure that any complications are identified and treated promptly.
  • Supportive care: Children with kwashiorkor may require additional support to manage symptoms such as edema and skin changes. This may involve wound care, medications to manage fluid accumulation, and other interventions as needed.
  • Follow-up care: Once the child’s nutritional status has been stabilized, ongoing follow-up care is essential to monitor their growth and development, and to ensure that they continue to receive adequate nutrition.

ComplicationsKwashiorkor and Marasmus

  • Infections: Malnutrition can weaken the immune system, making individuals more susceptible to infections. Children with kwashiorkor or marasmus may be at increased risk of developing bacterial, viral, and parasitic infections.
  • Growth retardation: Both kwashiorkor and marasmus can cause stunted growth and development. Children with these conditions may be much smaller than other children their age, and may experience delayed physical and cognitive development.
  • Anemia: Malnutrition can lead to anemia, a condition in which there are not enough red blood cells in the body. Anemia can cause fatigue, weakness, and other symptoms.
  • Organ failure: In severe cases, malnutrition can lead to organ failure. Children with kwashiorkor or marasmus may be at risk of developing liver or kidney failure, which can be life-threatening.
  • Changes in skin and hair: Malnutrition can cause changes in the skin and hair. Children with kwashiorkor may develop a characteristic rash, while those with marasmus may have dry, scaly skin and thin, brittle hair.
  • Mental health issues: Malnutrition can affect mental health and cognitive function. Children with kwashiorkor or marasmus may experience apathy, irritability, and other behavioral changes.
