Plasmodium vivax malaria during pregnancy, Bolivia
Emerging Infectious Diseases
|September 21, 2013
Summary
Pregnancy-associated Plasmodium vivax malaria is a significant concern in low-transmission areas. This study in Bolivia found P. vivax infections linked to maternal anemia and low birthweight, highlighting the need for prevention strategies.
Area of Science:
- * Infectious Diseases
- * Maternal and Child Health
- * Tropical Medicine
Background:
- * Pregnancy-associated malaria (PAM) is a significant global health issue, particularly in regions with low malaria transmission.
- * Plasmodium vivax poses a substantial burden in Latin America, Asia, and the Horn of Africa, yet its impact during pregnancy remains understudied in these areas.
Purpose of the Study:
- * To determine the prevalence of Plasmodium spp. infections among pregnant women in Bolivia.
- * To evaluate the health consequences of malaria during pregnancy on both mothers and newborns.
Main Methods:
- * A hospital-based survey of women giving birth and an antenatal survey were conducted.
- * Prevalence rates of Plasmodium spp. infections were assessed in pregnant women.
- * Outcomes such as maternal anemia and infant birthweight were analyzed in relation to malaria status.
Main Results:
- * Plasmodium vivax infection was identified in 7.9% of pregnant women attending antenatal visits.
- * Placental infection occurred in 2.8% of deliveries, with no significant variation based on parity.
- * P. vivax-infected pregnant women exhibited higher rates of anemia (6.5%) and delivered infants with reduced birthweight.
Conclusions:
- * Plasmodium vivax infections during pregnancy are associated with adverse maternal and neonatal outcomes, including anemia and low birthweight.
- * These findings underscore the importance of integrating P. vivax prevention strategies into antenatal care programs, especially in low-transmission settings.
- * Further research is warranted to fully characterize and mitigate the impact of P. vivax on pregnancy outcomes.

00:58Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:27Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
