Persistent diarrhea
Dr.P.soundararajan
Definitions
• Diarrhea with passage of 3 or more loose
stools of presumed infectious etiology starting
acutely and lasting for more than 14 days.
• Chronic diarrhea; noninfectious etiology
• Protracted diarrhea
– Persistent diarrhea with weight loss and malnutrition
Disease burden
• 24 lakh child deaths in India each year
• 5 children die every minute
• 25% of the global burden is in India
• More in infancy [31 episodes per 100 child
years]
25% of the global burden is in India
Causes
• Persistent multiple infections
• Parasitosis
• Malabsorption
• Protein allergy/ intolerance
Pathology
• Delay in repair of damaged epithelium of gut
• Damage of mucosal absorptive surface
• Loss of brush border enzymes
• Bacterial overgrowth  altered intestinal flora
• Prolonged cell mediated immune form of
damage of small intestinal mucosa
Presentation
• Mild form
– Several motions
– No significant weight loss
– No significant dehydration
• Moderate form
– Several motions
– Marginal weight loss
– Without dehydration
– Non tolerance to milk
• Severe form
– Dehydration with several motions
– Weight loss
– Non tolerance to milk & cereals
– Secondary infection
Diagnosis
• Asses dehydration.
• Asses malnutrition.
• Stool - R/E,
• Stool culture,
• Reducing sugar, pH.
• Mild PD: low milk diet
– 50ml milk+2tsp puffed rice powder+ 1tsp oil+ 1.5
tsp sugar +100ml boiled water
– Rice with curd
– Milk sooji gruel
– 85kcal, 2g protein.
– 6-7 feeds / day
• Moderate PD: no milk diet
– Egg white 1.5 + 3tsp cooked rice+ glucose & oil
1.5tsp+ 120ml boiled water
– 90cal, 2.4g protein.
• Severe PD: no milk, no cereal diet.
– Phase I: Resuscitation < 24 hours
– Phase II: PPN(1-4 days), IV fluids, plasma, antimicrobials, electrolyte
balance
– Phase III: > 5 days Nutritional rehabilitation with calorie dense, lactose
free formulae
– Chicken puree 5tsp or 1.5 egg white + glucose & oil
1.5 tsp+150 ml water
– 67cal , 3g protein
Micronutrients
• Vitamin A: single dose 2L iu >1yr child
• Twice RDA of zinc, copper, folate, vitamin D
• Zinc: 20mg/day 2-4weeks
• Mg sulphate i.m 0.2ml/kg/day bid 2-3days
• Potassium 5-6meq/kg/day
Antibiotics
• Blood in stool [quinolones]
• Systemic sepsis [ampicillin & amikacin]
• Severe malnutrition
• Young infants
• Discharge criteria
• Regular diet: when?
Probiotics?
• Lactobacillus GG
• Saccharomyces boulardii
• Bifidobacteria
Prevention
• Prompt treatment of AWD
• Judicious use of antibiotics
• Diet management
• Vaccines
• Promotion of breast feeding
CHRONIC DIARRHEA
Definition
• Diarrhea of more than 2 weeks duration or
3 attacks during last 3 months.
• With specific congenital, biochemical or
metabolic disorders.
• Non infectious
• Osmotic
• Secretory
• Reduced anatomic surface
• Altered intestinal motility
• Inflammation
Causes
• CMPA / soy protein allergy
• PEM
• Lactose intolerance
• Post GE malabsorption
• Parasites
• Celiac disease
• Excessive intake of carbonated drinks
• Inflammatory bowel disease
• Irritable bowel syndrome
Osmotic diarrhea
• Lactase deficiency
• Carbonated drinks
• Antacids
Secretory diarrhea
• Activation of cAMP
• Activation of cGMP
• Activation of intracellular calcium
E.Coli
Shigella
Salmonella
cholera
CMPA
• Few weeks after introducing cow milk
• Diarrhea, vomiting, colic, GI bleed, FTT.
• Due to IgA deficiency?
Celiac disease
• Intolerance to wheat gliadin
• Features
– Chronic diarrhea
– Abd distension
– FTT, anorexia, irritable
– Foul, greasy,bulky stool.
• Diagnosis:
– anti endomysial antibody
– Villous atrophy
• Management
Work up
• History of intake of fluids
• Nutrition assessment
• Stool pH / RS / WBC / ova ,cyst / cl.difficile culture
• Stool fat estimate
• Breath H2 estimate
• Stool electrolytes
• Sweat chloride
• Small bowel biopsy / endoscopy
• Barium studies
• Hormones assay
Case scene 1.
• 8 month old child presents with 18 days of
loose stools, many episodes per day following
milk feeds. initially treated with antibiotics for
1 week.
• On exam, no dehydration, 3% weight loss+,
perianal excoriation +
• What stool exam you do?
• Diagnosis & management?
Scene 2
• 7 month old child 2 weeks after introduction
of cow’s milk, cries irritably frequently, loose
stools many episodes,
• O/E ; irritable, poor weight gain,
• Stool occult blood positive.
• One more stool exam to do?
• Diagnosis?
Scene3
• 2year old child,3 weeks diarrhea, stools are
bulky, oily, foul smelling, not responding to 2

Thank you

Editor's Notes

  • #3 Comp- gf.mn. Gf not due malabs, poor cal intake, poor diet managemt.
  • #4 Cn in mn.major are well hydrated. Most can be managd at home. Admit <4m, dehyd,system inf, severe mn wt <60%
  • #10 1 normal 5days
  • #13 Palatable, acceptable
  • #14 Less starch glucse.
  • #17 Live microbial feed supplement, which beneficially affects host by improving the host intestinal microbial balance“ secrete iga, produce lactate
  • #20 Low purge, recurrrent, abd dist, mn
  • #21 Loose bulky celiac, pasty yellow pancreas, urinelike chloride, toddlers –freq hetero mucus foul alternate normal stool nn. 3 celaic-post age- 1undiges nutrients break into short chain fatty acids.3=nec. 4=mn-dm
  • #23 lactose is not absorbed in the small intestine and reaches the colon intact The colonic bacteria ferment the nonabsorbed lactose to short-chain organic acids, generating an osmotic load and causing water to be secreted into the lumen
  • #24 activation of the intracellular mediators such as cAMP, cGMP, and intracellular calcium, which stimulate active chloride secretion from the crypt cells and inhibit the neutral coupled sodium chloride absorption Patients with chloride diarrhea have hypochloremic metabolic alkalosis with low serum chloride concentration, high stool chloride content coupled with chloride-free urine, low serum potassium, and high serum bicarbonate. Hydramnios is present in the mothers.
  • #25 Jeju bx- villous atrophy
  • #27 1encopresis? Breath hydrogen tests can be used to determine a specific carbohydrate malabsorption. A breath hydrogen test for glucose or lactulose can be used to diagnose bacterial overgrowth. Sorbitol, which is a nonabsorbable sugar, is found in apple, pear, and prune juices, and can cause diarrhea in toddlers. Moreover, apple and pear juices contain higher amounts of fructose in excess of glucose concentration, a feature postulated to cause diarrhea in toddlers
  • #28 Juice >150ml/kg/d? <90ml/kd
