Kwashiorkor pathophysiology pdf
Kwashiorkor patients are characterized by a distended stomach, burns on the skin and diarrhea. The relationship between protein energy malnutrition (PEM) and malaria is controversial. Various extensive reviews of the pathophysiological processes resulting in marasmus are available. Refeeding problems have been recognised since the the liberation of starved communities under siege. PATHOPHYSIOLOGY Total body water is divided between the intracellular and extracellular spaces. Kwashiorkor is a disease syndrome resulting from a severe deficiency of dietary protein relative to caloric intake.
Key Difference: Kwashiorkor is a form of malnutrition that is caused due to insufficient intake of proteins, whereas Marasmus is caused due to insufficient intake of proteins, fats and carbohydrates. As well as hunger arising from insufficient energy intake, deficiency in protein can lead to kwashiorkor (swelling under the skin and loss of muscle mass), marasmus (loss of fat and muscle) and sarcopenia (loss of muscle mass, particularly in older people). Aging: the accumulation of injury caused by free radicals over the year may be reSPOnsible for cellular aging. The prevalence of marasmus was highest in the 6 to 12 months age groups of (34.3%) and (36%) for males and females, respec-tively. 8 CONTROLLING AND PREVENTING DISEASE The environment: the environment in which transmission of the pathogen takes place. The mechanism of periportal fatty liver caused by dietary protein deficiency was investigated in the rhesus monkey by studying the pattern of Triton-induced hypertriglyceridemia. Kwashiorkor is another severe form of protein-energy malnutrition where the main deficiency is protein. It is globally the most important risk factor for illness and death, with hundreds of millions of pregnant women and young children particularly affected.
Until she began developing the symptoms of Kwashiorkor, including general fatigue, edema of the face and extremities, anemia, alopecia, and weight loss, she had been leading a normal life post-gastrectomy. Acute malnutrition is a nutritional deficiency resulting from either inadequate energy or protein intake. pathophysiology is characterized by a negative protein and energy balance driven by a variable combination of reduced food intake and abnor-mal metabolism. These codes are to be used for easy reference; however, the ICD-9-CM code book is the authoritative reference for correct coding guidelines. pathophysiology of CHF to an increasingly complex approach involving neurohormonal and immunological aspects [7, 22, 105, 108]. Learn more about the forms such imbalance can take, the conditions that can cause it, the complications that can develop, and the appropriate treatment methods. We tend to visualise malnutrition as solely affecting starving children in the developing world but it is common at home, particularly in elderly and hospitalised populations and massively increases a patient's vulnerability to disease.
There is retarded growth and development, a protuberant abdomen, muscle wasting, tissue fluid retention ( OEDEMA ), red discolouration of the hair, irritability or apathy and enlargement of the liver. The interaction between undernutrition and infection can create a potentially lethal cycle of worsening illness and deteriorating nutritional status. Kwashiorkor usually manifests as edema, changes in hair and skin color, anemia, hepatomegaly, lethargy, severe immunodeficiency and early death (17, 18). We report herein the case of a 56-year-old woman who developed secondary Kwashiorkor 9 years after undergoing a total gastrectomy for early gastric cancer. Severe acute malnutrition is the most extreme and visible form of undernutrition. The long-term effect of severe malnutrition on growth and mental development remain uncertain as these children are also affected by a deprived environment.
In 1933, a paediatrician, Cicelly William, working in West Africa used the local term Kwashiorkor which means ‘displaced child’ meaning “the sickness which a child develops when the next baby is born and the older one gets deprived of breast milk”. Its epidemiology, determinants and aetiology, nomenclature, pathophysiology, case management and ultimately prognosis has kept many –practitioners, scientists and policymakers- lifelong intrigued and involved. Lack of protein results in an osmotic imbalance and irregularities in the lymphatic system. interpretation of studies based on the comparison of the pathophysiology of marasmus and kwashiorkor as they refer to different comparison groups.
Of the two, kwashiorkor is consistently the more lethal, with … It is the primary or associated cause of around half of the nearly 11 million annual deaths among children under five, 30 000 each day.1 The reasons for this tragedy are quite clearly poverty, underdevelopment, and inequality, yet knowing this does not translate into finding correspondingly obvious or immediate solutions. While the Marasmus occurs due to energy deficiency, Kwashiorkor is attributed to protein deficiency, the two being most common in children. Kwashiorkor, a severe form of undernutrition, is usually the result of severe restrictions in protein intake and is characterized by edema (particularly ascites or abdominal swelling). The main sign of kwashiorkor is too much fluid in the body’s tissues, which causes swelling under the skin (edema). Kwashiorkor is a form of protein energy malnutrition commonly seen in poor countries where there is famine or a limited food supply.
About 25% of children with kwashiorkor die despite treatment.
The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin . Kwashiorkor is a form of protein-energy malnutrition (PEM) that occurs when there is not enough protein in the diet. Kwashiorkor •Frequent infections •Electrolyte imbalance •Frequent association with dehydration (often masked by oedema) • Generally apathetic, lethargic, miserable, and irritable.
They usually have mild cutaneous and hair manifestations and an enlarged palpable fatty liver. Approximately 52 million children have wasting with one-third (17 million) suffering from severe acute malnutrition.Even more children (∼ 154.8 million) have stunted growth, indicating widespread chronic malnutrition.
Children continue to be at high risk of morbidity, mortality and relapse after discharge from hospital although long-term outcomes are not well documented. The pathophysiology of edema varies based on the type of edema the sufferer experiences. The syndromes of severe undernutrition, marasmus and kwashiorkor, have causes related to the interplay of social and medical considerations in the society.
Kwashiorkor is most often encountered in developing countries in which the diet is high in starch and low in proteins. P EM or Protein-Energy Malnutrition is a macro-nutrient deficiency rather than micro-nutrient deficiency. Marasmus, a form of protein-energy malnutrition occurring chiefly among very young children in developing countries, particularly under famine conditions, in which a mother’s milk supply is greatly reduced. fisiopatología tema lesion celular cuando la célula se altera, se altera el órgano el sistema. 1, 2 The World Health Organization (WHO) defines malnutrition as "a cellular imbalance between supply of nutrients and energy and the body's demand for them to ensure growth, maintenance, and specific functions". En todos los casos que se da el Kwashiorkor se presentan signos y síntomas que pueden agruparse en las siguientes categorías: Los signos universales, que son. 12% of the global population is estimated to be currently at risk of protein deficiency26. Reanalysis of this evidence and a review of the literature demonstrates that this was a mistaken conclusion and that the oedema is linked to hypoalbuminaemia.
The loss of weight in the hospitalized patient or in association with mild chronic disease is often not severe, but it is significant. Kwashiorkor is a form of severe protein malnutrition characterized by edema and an enlarged liver with fatty infiltrates.
While the historic syndromes of marasmus, kwashiorkor, and protein-calorie malnutrition remain in use, this chapter will instead highlight new insights to the diagnosis of malnutrition syndromes. The excessive retention of interstitial fluid characteristic of edema may be caused by an overconsumption of salt or failure to properly excrete sodium from the body. Protein malnutrition: Insufficient intake of nitrogen-containing food (protein) to maintain a nitrogen balance or nitrogen equilibrium. Unlike marasmus, kwashiorkor causes the body to retain fluid in the lower legs, feet, arms, hands, and face, leading to a swollen appearance. 536 UNIT V / Responses to Altered Nutrition Home Care Clients with malnutrition may be cared for at home or in the hospital with diet, enteral, or parenteral therapy. Medwave es una revista electrónica revisada por pares y de acceso gratuito, que contiene artículos originales de revisión sobre determinantes clínicos, sociales, políticos y económicos en salud, y de investigación en el ámbito clínico y biomédico. Hypertension is a condition in which blood pressure within the aorta and systemic arterial circulation is elevated. Toxicities of fat-soluble vitamins can also be caused by a large intake of highly fortified foods, but natural food rarely deliver dangerous levels of fat-soluble vitamins.
Protein is the most common cause of malnutrition-related edema in the body.
A brief video describing the major pressures in capillary filtration as well as how those pressures are altered in edema. Characteristically, children with marasmic kwashiorkor have concurrent gross wasting and edema. Kwashiorkor happens when there is a deficiency in the protein diet of a child whereas Marasmus is the result of a deficiency of protein, carbohydrates and fats in the diet of a child. Lactase is the enzyme that helps to digest milk lactose, releasing galactose and glucose. It is characterized by rapid development of edema, hypoalbuminemia, and distinct skin dyspigmentation. Nearly half of all deaths in children under 5 are attributable to undernutrition; undernutrition puts children at greater risk of dying from common infections, increases the frequency and severity of such infections, and delays recovery.
It usually begins in the legs, but can involve the whole body, including the face. In general, marasmus is an insufficient energy intake to match the body’s requirements. This chapter reviews the pathophysiology of cholera, focusing on the most common and important complication, dehydration; describes the clinical features of patients with cholera; and outlines treatment for patients with this disease. Various infectious agents, toxins, and prooxidants have been all implicated in the pathophysiology of this complex condition. A decrease in serum albumin concentrations is an almost inevitable finding in disease states, and is primarily mediated in the acute phase by alterations in vascular permeability and redistribution. It is characterized typically by retardation of growth and development, edema, fatty enlarged liver, anorexia, and alterations in the color and texture of the hair and the skin.
PROTEIN ENERGY MALNUTRITION (PEM) The term protein energy malnutrition covers a wide spectrum of clinical stages ranging from the severe forms like kwashiorkar and marasmus to the milder forces in which the main detectable manifestation is growth retardation.It is widely prevalent among weaned infants and pre-school children in India and other developing countries. To grow, children have to consume enough nitrogen-containing food (protein) to maintain a positive nitrogen balance, whereas adults need only be in nitrogen equilibrium. We investigated whether these mediators might be involved in the oedematous malnutrition syndrome kwashiorkor. Kwashiorkor results from relative protein deficiency in the setting of adequate energy intake and is characterized by hypoproteinemia, pitting Pathophysiology. Its face is a child – frail and skeletal – who requires urgent treatment to survive. The main clinical problems may relate to hypophosphataemia, hypomagnesaemia and hypokalaemia with a risk of sudden death; thiamine deficiency with the risk of Wernike’s encephalopathy/Korsakoff psychosis and sodium/water retention. Clinical guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate nutrition care for specific clinical circumstances. Marasmus is a form of severe malnutrition characterized by energy deficiency.It can occur in anyone with severe malnutrition but usually occurs in children.
It is most often caused by both quantitative (number of kilocalories/day) and qualitative (vitamins and minerals, etc.) deficiencies. Moderate acute malnutrition (MAM), also known as wasting, is defined by a weight-for-height indicator between -3 and -2 z-scores (standard deviations) of the international standard or by a mid-upper arm circumference (MUAC) between 11 cm and 12.5 cm. Kwashiorkor is a syndrome seen in children almost exclusively in association with famine in the tropics. The diseases known as ‘kwashiorkor’ and ‘marasmus’ represent extreme forms of protein calorie malnutrition. Severe acute malnutrition (SAM) is caused by a significant imbalance between nutritional intake and individual needs.
Only a few studies have been concerned with this condition, and the reason for the development of DoK remains unexplained. The extracellular space, which com-prises about one third of total body water, is composed of the intravascular plasma volume (25%) and the extravas-cular interstitial space (75%) (1). When there is increased functional demand, the cell may adapt to the changes which are expressed morphologically, which then revert back to normal after the stress is removed (cellular adaptations).
