Foetal Growth Restriction -Prevention and Treatment : What is newer modality of Tr by NAC & Creatine sachet and gene therapy

 

We, the practicing obstetrician how should we prevent  of intrauterine growth retraction before such an adverse outcome occur??

Prophylaxis of FGR: How? What should we attempt ?? In an established case  of FGR one  Part I:---Some factors  may increase  the risk of IUGR such as  a)  cigarette  smoking b)  intake of liquor   and c)  poor maternal  nutrition . These should be avoided or kept to minimum prenatally and intranatally. Therefore by avoiding such harmful  lifestyles   and  eating a healthy diet and getting  a regular prenatal  care hopefully will  decrease   the risks for     FGR . Regular    antenatal  checkup for early  detection of FGR  may also  help   in appropriate treatment    and good  outcome.

Treatment f FGR :  Part II :- However once FGR is established medical treatement is not that much effective. One can't increase the wt much...its only timely delivery which can prevent IUD and other neonatal complications…

Part III:  Etiology of FGR :  Foetal growth restriction (FGR) and associated placental pathologies such as pre-eclampsia and stillbirth arise in early pregnancy when inadequate remodeling of maternal spiral arteries leads to persistent high-resistance low-flow uteroplacental circulation. Current interventions concentrate on targeting the placental ischaemia-reperfusion injury and oxidative stress associated with an imbalance in angiogenic/anti-angiogenic factors.

Part IV: Early prediction and drugs for prevention?? Recent meta-analyses confirm that 1) aspirin modestly reduces the risk for small-for-gestational-age pregnancy in high-risk women. A dose of ≥100 mg starting by 16 weeks of gestation is recommended. 

2) LMWH: -In vitro and in vivo studies suggest that low-molecular-weight heparin may prevent FGR; further research is needed to confirm efficacy.

 

Part V: How to treat FGR Once FGR is diagnosed??  Ans No treatment will improve foetal growth. Potential FGR therapies such as phosphodiesterase type-5 inhibitors or maternal VEGF gene therapy aim to improve poor placentation and/or uterine blood flowMelatonin,  creatine and N-acetyl cysteine have potential as novel neuroprotective and cardio protective agents in FGR and may avoid autism, behavioural disorders in adult life.

 

We ,the practicing obstetricians  have to react as per DFMC, AFI, MVP and  with Doppler results to plan time delivery.ne can go through and adhere to diffident guidelines issued by different academic bodies including green top guidelines on IUGR which is   simple to follow but main index of induction of labour is Doppler which has revolutionized FGR management...

.

Is there any drug which can increase the foetal wt  or catch up the EFW/AFI/MVP??  

 · 

 There is no firm documentation that external therapy in the form of vitamin or protein  supplements are proven benefit but people do prescribe in a desperate attempt to improve foetal wt & AFI/MVP.

A)      . A) If early NT scan shows high PI in uterines then ecosprin is added in the dose of 150mg a bedtime.

B)      arginine supplements as sachets argihope in tablet form

C)       Inj: Hermin IV OD thrice a week - alternate day. Inj alamine/Hermin over 3/4 hours slowly as they may cause allergic reaction

D)     Routine iv fluid RL,DNS  around 2 liter as twice/thrice a week

E)       Rest for 2 hrs in day and 8 hrs in night minimum

If nonveg: 2 boiled egg daily & Fish 4 pcs . Meat /Curd etc For Veg:- Pulses/Curds & Protein powder sprouts included daily

F)        Omega 3 fatty acids ,E cod plus, Femo only DHA)Era) ,E-Cod soft gel,  

G)     some use  vaginal sildenafil in these cases

H)     Different Brand names that are used are B complex series –like Beconex –GX, Multivite FM, Bevon CD

I)           Arginine: Argihope plus (mankind). Arginix F (Era), Argin 3 Gm(Fourtts) , L-Argin (TTK), Fetlar(Arex),

J)          Protein  Powders : Revitalite ( Ranbaxy), Alprovit (Alkem) ,Nutramide tab(Cipla),Aminofit(Sanofi)

K)     Lycopene:-Lycogold,

 

 

 

 

Creatine sachet in tr of FGR!!!!!! Stretch your imagination: Post delivery well being of neonate/infant where there is an anticipation that fetus is so growth retarded that it has to be taken out by 30-234 weeks?? In such settings in addition of L arginine, Multivitamin, Sildenafil vaginal, will creatine sachet administerd orally reduce subsequent MR (mental retardation) , autism, or behavioral/Learning disorders after a FGR is born preterm . I have a feeling that creatine sachets (many brands are available in Indian market designed for nerve growth) will act better than Mag So4.

 

Why creatine sachets in FGR?? High creatine intake does not greatly increase plasma creatinine concentration, and increases only the excretion of creatine, not of creatinine (Poortmans and Francaux, 1999).

How does oral suppl f creatine helps in FGR foetus??   Ans:  Creatine and creatine phosphate play important roles in regulating cellular adenosine triphosphate reservation. The function is impaired in cerebral creatine deficiency syndromes. This group of disorders includes a defect of the X-linked creatine transporter (XCrT) as well as deficiencies of two enzymes involved in de novo creatine synthesis, arginine-glycine amidinotransferase (AGAT) and guanidinoacetate methyltransferase (GAMT).

Major clinical features include seizures, intellectual disability, autism, and speech delay. While there is a significant amount of phenotypic overlap, these disorders are distinct in their presentation and pathogenesis. Laboratory diagnosis of these disorders relies on the determination of creatine and guanidinoacetate in both plasma and urine. Whereas determination of plasma creatine and guanidinoacetate levels are used for detecting AGAT and GAMT deficiencies, measurement of urinary creatine to creatinine ratio is a sensitive screening for XCrT deficiency. Management of cerebral creatine deficiency syndromes generally includes creatine supplementation and attempts to reduce offending intermediates such as guanidinoacetate. Do members’ believe that VEGF gene therapy aiming  to improve poor placentation and/or poor  uterine blood flow will minimize  FGR?? . How many member have a feeling that Melatonin, creatine  and N-acetyl cysteine have potential as novel neuroprotective and cardio protective agents in established FGR.?
