Overview
The incidence of congenital methemoglobinemia in the United States is very low. There is no racial predilection to methemoglobinemia. The highest prevalence of G6PD deficiency is observed in the malaria-endemic regions: Sub-Saharan Afria, West Asia and Arabian Peninsula, as well as in people of Mediterranean descent.
Epidemiology and Demographics
The incidence of congenital methemoglobinemia in the United States is very low.
Age
- Patients of all age groups may develop methemoglobinemia.
- The acquired methemoglobinemia is a rare disease that tends to affect infants and people exposed to local anesthetics during medical procedures.
- Infants, particularly those younger than 4 months are most susceptible to methemoglobinemia. This is due to the fact that the NADH methemoglobin reductase activity and concentration (the main protective enzyme against oxidative stress) is not fully mature in infants.
Gender
- The incidence of the congenital methemoglobinemia is the same for both genders as both cytochrome b5 reductase deficiency and pyruvate kinase deficiency are autosomal recessive diseases and the Hb M has autosomal dominant pattern of inheritance.
- The incidence of ([G6PD]] deficiency is is greater in males as this condition has X-linked pattern of inheritance. There is no racial predilection to Methemoglobinemia.
Developed Countries
- There is no racial predilection to methemoglobinemia.
- In developed countries, the incidence of acquired methemoglobinemia is higher in developing countries when people are exposed to local anesthetics during various medical procedures.
- The majority of cytochrome b5 reductase deficiency cases are found among some Native American tribes like Navajo [1] and Athabaskan Alaskans, and the Yakutsk people in Siberia. [2]
Developing Countries
- The highest prevalence of G6PD deficiency is observed in the malaria-endemic regions: Sub-Saharan Afria, West Asia and Arabian Peninsula, as well as in people of Mediterranean descent. [3] [4] [5]
