bull Home-made recipes

Developing countries

ldquo1113 children with the PD syndrome of infancy were successfully treated with human milk All the infants who were severely malnourished had deteriorated while fed on a wide range of highly modified formulas (extensively hydrolysed and chicken based)

Despite its high lactose content human milk has nutritional and immunological properties that may reverse many of the factors thought to cause PD syndromerdquo

Available Formulae

Cowrsquos milk based Formulae

Soy based formulae

Hydrolysed protein based formulae

Amino acid (Elemental diets) based Formulae

The standard management of severe malnutrition involves nutritional rehabilitation with lactose-based high energy formula milk

However some of these children may be lactose intolerant possibly contributing to the high rate of unfavorable treatment outcomes

What is the role of lactose Free diets

Solomons NWet al Am J Clin Nutr 1984

The routine reduction of lactose content from a milk-based diet for severe protein-energy

malnutrition offers no advantages

Severely malnourished diarrhea (n=196 3-60 months)

(255) had evidence of lactose intolerance (stool reducing substance ge 1 + [05] and stool pH lt 55)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Nutrition Content of Modular Feeds How Accurate is Feed Production

Biochemical nutrient analysis was inaccurate for both feeds but was better for the 2-IF

Preparation errors included

Incorrect use of equipment poor recipe adherence and ingredient measurement mistakes

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

All patients with PD admitted over a period of 2 years (n=235) Age= 42 plusmn 20 years none had severe PEM Randomized to receive ORS alone (n=117) or ORS plus LGG powder (n=118) containing 60 million cells twice daily for a minimum period of 7 days or till diarrhea has stopped

bull Participants who regularly prepare special feeds at home were observed preparing two feeds with equivalent nutrient composition a 2-ingredient (2-IF protein free powder water) and 6-ingredient feed (6-IF glucose polymer micronutrient powder 50 fat emulsion NaCl KCl water)) under research-conditions and 8 weeks later under home-conditions

bull The same feeds (2-IF and 6-IF) prepared by a trained feed-maker served as controls

Nutrition Content of Modular Feeds How Accurate is Feed Production

Biochemical nutrient analysis was inaccurate for both feeds but was better for the 2-IF

Preparation errors included

Incorrect use of equipment poor recipe adherence and ingredient measurement mistakes

Even in control-feeds there was equipment inaccuracy poor ingredient emulsification and residues left in mixingmeasuring containers

Fewer errors occurred with powdered than liquid ingredients

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)

Conclusions and Recommendations

bull In developing countries most cases of persistent diarrhea are caused by a combination of enteric infections under-nutrition and impaired immune system function

Conclusions and Recommendations

bull The first step in evaluating a child with persistent diarrhea is to diagnose dehydration malnutrition and associated non-enteric infections

bull The next step is to classify the diarrhea based on its appearance as bloody diarrhea is most likely caused by Shigellawhich confers a worse prognosis and requires antimicrobial treatment

bull Laboratory testing of stool is not essential

Conclusions and Recommendations

bull The first step in treatment is to stabilize children with severe infection or dehydration according to standard protocols

Conclusions and Recommendations

bull The main component of treatment is nutritional rehabilitation many children have a secondary carbohydrate intolerance and respond better to a low-lactose diet

Conclusions and Recommendations

bull It is recommended that all children with chronic diarrhea be treated with zinc supplementation (Grade 1B) and vitamin A

Conclusions and Recommendations

bull Empirical antibiotic treatment is not generally recommended (Grade 1B)

bull In children with bloody diarrhea empiric therapy directed against Shigella is suggested (Grade 2B)

bull Antimicrobial treatment is also suggested for patients with severe symptoms and suspected or proven cholera (Grade 2B)
