Reducing Iron Deficiency Anemia Through Treatment for NTDs

Iron deficiency is the most prevalent nutritional disorder in the world. It affects millions of children and women, primarily in developing countries. According to the World Health Organization (schistosomiasis (or snail fever). These NTDs cause blood loss, which leads to anemia and iron deficiency.

Iron deficiency anemia is known to complicate pregnancy, child birth, and early childhood growth and development. Approximately one-third of all pregnant women in developing countries are infected with hookworm, which contributes to iron deficiency anemia. Infection with genital schistosomiasis causes genital lesions, which have been associated with ectopic or tubal pregnancies, as well as increased risk of HIV infection. Addressing iron deficiency anemia needs to be a main component in all efforts to improve maternal, newborn, and child health (MNCH).

The great news is that there are cost-effective solutions available today that can dramatically lower the rates of iron deficiency and anemia and improve the lives of millions of children and their mothers. The WHO developed a comprehensive strategy to address iron deficiency and anemia, which focuses on three main lines of action:

  • Increasing iron intake, by including iron-rich foods, food fortification and iron supplementation;
  • Controlling infection through immunizations and control programs for malaria, hookworm, and schistosomiasis; and
  • Improving nutritional status through vitamin B12, folate, and vitamin A supplements.

In the region of the Americas, the Pan American Health Organization (PAHO) has been addressing these issues for several years, particularly during Vaccination Weeks. Vaccination Weeks in the Americas (VWA) have contributed significantly to the reduction of morbidity and mortality in all age groups, particularly among children. Since the first VWA was celebrated in 2003, VWA have served as the perfect platform for delivering comprehensive solutions to improving child health. Deworming treatment, iron “sparks” and vitamin A supplements are commonly distributed along with vaccines that protect children against preventable diseases such as measles, rubella, yellow fever, diphtheria, tetanus, polio, and influenza. By facilitating people’s iron intake and distributing deworming medication along with vaccines during vaccination weeks, children and pregnant women in all regions of the world can receive protection against the threats of iron deficiency and anemia.

The potential of using this platform for distributing iron supplements and deworming medication is significant – PAHO estimates that over 400 million people in the Americas have been vaccinated through the VWA. Throughout the world, other regions are also taking advantage of this opportunity through the WHO Regional Offices: the European Region (EURO) began holding its Immunization Week in 2005, followed by the Eastern Mediterranean Region (EMRO) in 2010, the African Region (AFRO) and the Western Pacific Region (WPRO) in 2011, and finally, the South-East Asia Region (SEARO) in 2012. World Immunization Week is now a reality endorsed by the World Health Assembly to be celebrated every year around the third week of April. This major mobilization will carry other key interventions like deworming and iron supplements to every village.

The WHO program to jointly address iron deficiency and anemia is already being implemented in countries that have high levels of iron deficiency and anemia, malaria, and schistosomiasis and STH infections. It is our hope that through programs like this, along with the opportunities provided by vaccination weeks, the health burden caused by iron deficiency anemia will continue decreasing, so that mothers and children can have a real chance at growing healthy and thriving in life.

A Closer Look at Neglected Tropical Diseases

Global Health Council Conference, I attended an interesting event, “Impact of Schistosomiasis and Polyparasitic Infections on Anemia, Growth and Physical Fitness in Children in Coastal Kenya” presented by  Dr. Amaya Bustinduy of Case Western Reserve University which focused on neglected tropical diseases (NTD).

Schistosomiasis remains one of the most serious and prevalent neglected tropical diseases worldwide.  According to Bustinduy, the WHO estimated that there are 235 million cases of schistosomiasis with 732 million to be at risk for contraction. 89% of  all cases live in the less-developed areas of rural sub-Saharan Africa and South America.

Schistosomiasis is associated with diseases such as anemia, growth impairment in children, and mental retardation.  The focus of Dr. Bustinduy’s ongoing study in Kenya is to “address those morbidities as part of a larger study examining the ecology of transmission of Schistosomiasis.”

The study found that the presence of schistosomiasis is associated with growth retardation and anemia, which can lead to cognition problems, decreased productivity, as well as a reduced quality of life.  The objectives of the study were to measure the prevalence of schistosomiasis and assess current trends (as related to child growth, wasting, stunting, anemia and multiple infections when compared to the WHO growth standards for children). Measurements taken included height- for- weight to assess chronic malnutrition, mid-upper arm circumference (MUAC) to assess acute malnutrition and a fitness test (the 20 meter shuttle run). The study found anemia was present in 50% of the children. There was a high level of co-infection for children 5 to 7 years of age, in particular with malaria and hookworm. The goal of the research is to leverage this data in order to scientifically show a link between NTDs and poverty and create a prevention program on a national level.

With the recent G-8 announcement, it is clear that donors are becoming more interested in neglected tropical diseases (NTD) as well as analyzing the links between these diseases and how they affect  overall health outcomes such as poor nutrition and anemia-underlying factors that can often affect an individual or a community’s productivity and eventual economic gains. Therefore, there is a strong potential of integrated parasite control in efforts for poverty reduction.
