Prevensi Primer dengan susu Formula

FORMULA H.A.Partially hydrolyzed formulas:

16

Prof DR Dr Ariyanto Harsono SpA(K)

Tujuan Prevensi Primer

1. Menimbulkan Toleransi Oral

2. Menurunkan prevalensi alergi

17Prof DR Dr Ariyanto Harsono SpA(K)

Formula HA dalam Pencegahan primerBagaimana seharusnya?

*Harus mengandung sejumlah kecil protein SS

*Tujuan adalah menginduksi toleransi imun, bukan eliminasi SS

*Harus mengandung kasein dan whey supaya terjadi toleransi thd keduanya

*Probiotik: dapat menyebabkan supresi deviasi imun

US Nutrition guidelines

18Prof DR Dr Ariyanto Harsono SpA(K)

Induction of Oral Tolerance

T-cells regulation:

1. Intra Epithelial Lymphocytes: extrathymically derived, have limited TCR repertoir, capable of recognizing common microbiologic Ags, and demonstrate predominantly cytolytic functions

2. Lamina Propria Lymphocytes: thymicaly derived, contributes to limiting TCR/CD3-mediated signals in the mucosa.

• Vitamin A juga dikenal dengan nama retinol  merupakan vitamin yang berperan dalam indra penglihatan yang baik, terutama di malam hari, dan sebagai salah satu komponen penyusun pigmen di retina. Selain itu, vitamin ini juga berperan penting dalam menjaga kesehatan kulit dan imunitas tubuh. 

• Apabila terjadi defisiensi vitamin A, penderita akan mengalami rabun senja dan katarak, mudah mengalami infeksi saluran pernafasan.

* Lipid-soluble vitamin E has a capacity of defense against oxidant-induced membrane injury. Studies have consistently demonstrated beneficial associations between dietary vitamin E and ventilatory function, and few have demonstrated beneficial association with asthma and atopy.

Water-soluble vitamin C provides anti-oxidant capacity primarily by scavenging oxygen free radicals and suppressing macrophage secretion of super oxide anions, therefore play a role in preventing mucosal shedding caused by mediators released from eosinophils and oxydants.

n-3 polyunsaturated fatty acid (Omega-3), eicosapantaenoic acid, and docahexaenoic acid might have contributed to the decrease in asthma and atopic disease morbidity.

24Prof DR Dr Ariyanto Harsono SpA(K)

Phytoestrogen Biological consequences of soy-rich diets

have been attributed to the presence of soy isoflavones, which are members of the phytoestrogen family.

Phytoestrogens are plant-derived, estrogen-like compounds capable of interacting with the estrogen receptors ER and ER because their structure resembles that of the endogenous hormone 17-estradiol.

Adrenocortical effects of oral estrogens and soy isoflavones in female monkeys.

Results of study suggest that long-term estrogen treatment may contribute to an androgen-deficient and hypercortisolemic state in animal model.

26Prof DR Dr Ariyanto Harsono SpA(K)

Phytoestrogen...

Four groups of phenolic compounds are classified as phytoestrogens:

isoflavones, stilbenes, coumestans, and lignans. The main isoflavones, found mostly in soybeans,

are: genistein, daidzein, and glycitein.

J. Clin. Invest. 2006 116:16-1927Prof DR Dr Ariyanto Harsono SpA(K)

Phytoestrogen...

Several epidemiological studies have concluded that phytoestrogens confer:

cardioprotection by downregulating cardiovascular disease risk markers,

consistent improvement in endothelial function

Soy product consumption has been associated with the following:

reduced serum cholesterol levels via reductions in total and low-density lipoprotein levels;

vasodilatory activity under certain conditions

enhanced activity of certain antioxidant enzymes to increase antioxidant activities.

IMMUNOMODULATORY AND IMMUNOSUPRESSIVE EFFECTS OF

PUFAs

PUFAs modulate :

1. Cytokine production

2. Lymphocyte proliferation

3. Surface molecule expression

4. Phagocytosis and apoptosis

5. Inhibit natural killer (NK)cell activity

N-3 PUFA are better than n-6 PUFA The ratio of n-3 to n-6 may be an

important factor in modulating inflammation

Kesimpulan Pencegahan Primer dengan formula hipo-alergenik

harus dimulai sejak trimester pertama kehidupan, tidak menunggu terjadinya gejala alergi. Makanan tambahan seharusnya juga hipo-alergenik

Summary

1. In term infants, there are few indications for their use in place of cow milk-based

formula:• (a) for infants with galactosemia and hereditary lactase deficiency (rare) and • (b) in situations in which a vegetarian diet is preferred.

2. For infants with documented cow milk protein allergy, extensively hydrolyzed protein formula should be considered, because 10% to 14% of these infants will also have a soy protein allergy.

3. Most previously well infants with acute gastroenteritis can be managed after

rehydration with continued use of human milk or standard dilutions of cow milk-based formulas. Isolated soy protein-based formulas may be indicated when secondary lactose intolerance occurs.

40Prof DR Dr Ariyanto Harsono SpA(K)

4. Isolated soy protein-based formula has no advantage over cow milk protein-based formula as a supplement for the breastfed infant, unless the infant has 1 of the indications noted previously.

5. Soy protein-based formulas are not recommended for preterm infants.

6. The routine use of isolated soy protein-based formula has no proven value in the prevention or management of infantile colic or fussiness.

7. Infants with documented cow milk protein-induced enteropathy or enterocolitis frequently are as sensitive to soy protein and should not be given isolated soy protein-based formula. They should be provided formula derived from hydrolyzed protein or synthetic amino acids.

41Prof DR Dr Ariyanto Harsono SpA(K)

8. The routine use of isolated soy protein-based formula has no proven value in the prevention of atopic disease in healthy or high-risk infants.
