The Matlab service model was later successfully replicated in Ghana and was subsequently disseminated from Ghana to neighboring African countries
This year marks a major milestone in the history of icddr,b. Sixty years ago, at the onset of a major cholera pandemic, the then-SouthEast Asian Treaty Organization (SEATO) established a small laboratory in Dhaka named Cholera Research Laboratory to be operated under National Institutes of Health (NIH), USA.
Later in 1978, this became the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) through a Government Ordinance followed by a World Health Organization (WHO) meeting in Geneva in 1979, which was chaired by UNDP and attended by 50 participants of 26 developing and developed countries, and agencies. A memorandum of understanding was signed by eighteen of those countries and agencies endorsing the Centre as an international entity.
With funds from the Government of Bangladesh and others, icddr,b has produced some stunning breakthroughs in scientific innovation, treatment, patient management and disease prevention and helped save millions of lives globally.
Discovery of life-saving ORS
icddr,b developed and carried out the first successful trial of Oral Rehydration Therapy (ORT), now known as Oral Rehydration Solution (ORS), The results were published in The Lancet in 1968. Within a decade, WHO, UNICEF, UNDP and other INGOs promoted the use of ORS and delivered millions of ORS sachets every year across the world.
icddr,b also discovered Labon-Gur saline in 1978 which was subsequently scaled up across the country by health workers of BRAC and other NGOs.
In Bangladesh, ORS helped reduce diarrhoeal disease mortality among children under-five from 15.1 per 1000 to 6.0 per 1000 live births between 1980-2015. Over the same period, similar reductions were observed in the burden of diarrhoeal diseases.
In 2007, Fontaine, Garner, and Bhan estimated that more than 50 million children have been saved by ORS between 1982 and 2007 – that is on an average two million lives a year. Based on the estimates, the number of children saved from 1982 until 2019 could be more than 70 million.
In June 2012, The Lancet recognised ORS as “the most important medical discovery of the 20th century.”
Ending the discriminatory use of injectable cholera vaccine
In 1970, scientists found the only available and used whole-cell injectable cholera vaccine confers low protection. Subsequently, the 26th World Health Assembly in 1973 abolished the right of countries to require travellers from developing countries travelling to developed countries a certificate of vaccination against cholera saving billions of dollars.
Reducing fertility in Bangladesh and beyond
In 1977, Maternal, Child Health and Family Planning interventions began in Matlab, Chandpur, Bangladesh which was soon scaled up by the Government of Bangladesh. It resulted in a remarkable drop in fertility from 6.3 in 1975 to 2.1 in 2016 in Bangladesh after the scale-up.
The Matlab service model was later successfully replicated in Ghana and was subsequently disseminated from Ghana to neighbouring African countries.
Maternal and neonatal tetanus elimination
In 1980, scientists found that newborns of mothers who received a tetanus toxoid vaccine before pregnancy were 75% protected from neonatal tetanus. As a result of this finding, WHO, UNICEF and partners have immunised more than 154 million women in 53 countries and helped eliminate the disease from 47 countries.
The beginning of oral cholera vaccine (OCV)
In 1985, the first ever OCV trial was launched in Matlab, which eventually led to the development of easy-to-administer and affordable OCVs. This resulted in WHO stockpiling OCVs.
This resulted in WHO stockpiling OCVs. More than 50 million doses of OCVs have been distributed in cholera endemic countries across the globe saving millions of lives.
Icddr,b has also facilitated the knowledge transfer to Bangladesh and the country now has OCVs produced by a local company.
New Vibriocholerae O139 serogroup discovered
In 1993, New Vibrio cholerae O139 Bengal was identified and later characterised. The world was warned about the emergence of a new infectious pathogen allowing preventive measures in anticipation of its spread.
Guidelines for treating severe malnutrition
In 1999, an icddr,b protocol for ‘Management of Severely Malnourished Children’ saw a decrease in case fatality from 20% to less than 5%. This was later published in The Lancet and was endorsed by WHO in the South Asian region.
Zinc treatment for diarrhea
In 2002, scientists discovered that zinc treatment of diarrhea reduces overall mortality in young children. In 2004, zinc was recommended by WHO and UNICEF as the only treatment to be coupled with oral rehydration salts for the treatment of all diarrhea episodes. This has significantly helped many developing countries reduce child mortality.
Influenza vaccine significantly reduces illness in infants and mothers
Between 2008 and 2010, scientists found that if pregnant women were given influenza vaccine, it reduced illness by 63% in infants under six months and reduced respiratory infections among children and mothers by one third. It has also shown to increase newborns’ birth weight. The findings resulted in WHO to recommend maternal immunisation during pregnancy with flu vaccine. The article on the findings received the “Bruce Squires Award” in 2012 from the Canadian Medical Association Journal.
Scientific breakthroughs that ramp up polio eradication effort
icddr,b scientists have proved different doses and intervals of polio vaccines (bOPV, mOPV1, mOPV2 and fIPV) to be more effective than initially thought. This has resulted in WHO to revise and accordingly undertake vaccination campaigns in Pakistan, Afghanistan, Syria, Laos, India, Sri Lanka, Nepal, Bangladesh and other polio endemic countries.
These findings also helped to determine how to design the Global Polio Eradication Initiative to combat against type 2 poliovirus outbreaks. The articles published with these findings have received the Charles C. Shepard Science Award from CDC in 2016 and in 2019.
Ultra low-cost Continuous positive airway pressure (CPAP) device for severe pneumonia
In 2015, scientists invented an ultra low-cost bubble-CPAP for treatment of severe pneumonia in children, which has the potential to save thousands of infants from premature death. Large scale trials are underway in Bangladesh and in Ethiopia.
WHO has already endorsed bubble-CPAP oxygen therapy as one of the non-invasive ventilations for COVID-19 affected children with severe pneumonia and hypoxemia.
Microbes to combat malnutrition
The prestigious journal Science recognised icddr,b and the Washington University, USA’s research on microbes to combat malnutrition as one of the ten biggest scientific breakthroughs of 2019. This work has the potential to revolutionise the treatment of malnutrition in children in the days to come.
