A ample multi-state survey has shown that specialised prenatal diagnostic services for thalassemia and sickle compartment illness tin beryllium delivered safely and efficaciously done territory hospitals and referral networks, perchance bringing precocious preventive attraction person to families successful agrarian and semi-urban India.
The findings, published successful the diary Blood Global Hematology, travel arsenic India pursues its extremity of eliminating sickle compartment illness and substantially reducing the load of thalassemia by 2047.
The survey analysed outcomes from a prevention programme led by Bengaluru-based Sankalp India Foundation successful concern with State governments, the National Health Mission and fetal medicine specialists crossed Karnataka, Gujarat, Maharashtra, Andhra Pradesh and Madhya Pradesh.
2.18 lakh large women
Since 2021, much than 2.18 lakh large women crossed 82 districts and 87 maternity centres person undergone screening for haemoglobin disorders. Through a coordinated referral network, 2,092 invasive prenatal diagnostic procedures were performed, helping forestall 286 births affected by terrible haemoglobin disorders.
Unlike accepted models that necessitate families to question to metropolitan centres for prenatal diagnosis, the programme connected large women identified arsenic being astatine hazard to fetal medicine specialists located person to their homes.
“Traditionally, invasive prenatal diagnosis was disposable lone successful cities specified arsenic Delhi, Mumbai, Hyderabad, oregon Bengaluru. For galore families successful tribal and distant districts, travelling to these centres during gestation was simply not possible,” Rajat Kumar Agarwal, President of Sankalp India Foundation and corresponding writer of the study, told The Hindu.
He said the programme addressed this spread by linking screening centres with 26 existing fetal medicine centres and centralised diagnostic laboratories.
“We did not make caller centres of excellence. We utilized existing doctors, existing hospitals and existing expertise. Samples were collected locally and sent to accredited cardinal laboratories. The survey demonstrates that this attack is some harmless and effective,” helium said.
The screening programme covers some thalassemia and sickle compartment disease. “The trial utilized to place thalassemia is the aforesaid 1 utilized to place sickle compartment disease. From the beginning, we treated them arsenic portion of a combined screening programme,” Mr. Agarwal said.
District hospitals’ role

Researchers recovered nary illustration nonaccomplishment and minimal diagnostic failures contempt samples being collected crossed aggregate locations and transported to cardinal laboratories. The programme relied connected a integer platform, StopThal, to coordinate counselling, referrals, laboratory workflows, and diligent tracking.

Among families wherever the foetus was recovered to beryllium affected by a terrible haemoglobin disorder, astir two-thirds chose aesculapian termination of gestation aft counselling and informed decision-making.
The information outcomes were encouraging. Post-procedure spontaneous termination was reported successful lone 0.4% of cases, a fig that compares favourably with rates reported successful planetary literature.
Mr. Agarwal said 1 of the cardinal contributions of the survey was demonstrating that blase prenatal diagnostic services request not stay confined to ample tertiary centres.
“Many argumentation discussions presume that each precocious work requires caller infrastructure, caller buildings and caller investments. What this survey shows is that existing nationalist wellness systems tin beryllium strengthened and connected to execute the aforesaid outcome,” helium said.
Implications
The survey concluded that a three-step exemplary comprising screening done high-performance liquid chromatography (HPLC), molecular confirmation, and invasive prenatal diagnosis tin supply high-quality and resource-efficient services. The exemplary offers a scalable pathway for reducing the load of transfusion-dependent thalassemia and terrible sickle compartment illness crossed India.
Mr. Agarwal said the findings get astatine a clip erstwhile large-scale screening efforts are expanding nationally, but entree to prenatal diagnosis remains uneven.
