Impact of Malaria and 9 Parasitic Infections on Human Nutrition Athis Rajh Arunachalam, Vedanta S. Parasitic infections are widespread throughout the trop- ics and subtropics, particularly in developing countries where social and economic deprivation, poor hygienic conditions, malnutrition, and warm climates favor the spread of intestinal parasites. Infection with multiple parasite species (polyparasit- ism) also occurs not uncommonly . Parasite infections contribute to malabsorp- tion and chronic blood loss and, in children, lead to long-term effects on physical and cognitive development [3–5]. Malnutrition makes children more vulnerable to intestinal parasites, which in turn leads to even worse nutritional status, creating a synergistic relation that impairs growth and development. The relation between malnutrition, infections, and altered immune status is depicted in Figure 9. Commonly encountered parasitic infections and potential mechanisms of nutritional impairment are shown in Table 9. Malnutrition is responsible in some way for a Impact of Malaria/Parasitic Infections on Human Nutrition 225 little more than half (54%) of the 10. Malaria is caused by the Plasmodia species and is transmitted by the bite of female anopheles mosquitoes. Malaria remains a signifcant cause of mortality and morbidity world- wide (Figure 9. The signifcance of malarial disease can be recognized by the fact that there were an estimated 216 million clinical episodes of infestation in 2010 and approxi- mately 655,000 deaths. NutRitioN Nutrition plays a pivotal role in health, and malnutrition increases the susceptibil- ity to a large number of infectious diseases [32–35]. Children and pregnant women, 226 Nutrition–Infection Interactions and Impacts on Human Health Impact of Malaria/Parasitic Infections on Human Nutrition 227 who are typically affected by undernutrition, share the greatest burden of malarial illness . The interaction between malnutrition and malaria may contribute to a signifcant proportion of the disease burden globally. Despite malnutrition and malaria being major public health problems, there is a relative pau- city of studies directly examining the infuence of nutrition on the malarial burden. Although it seems intuitive that undernutrition increases the burden of malaria, stud- ies over the last several decades have shown that the interaction between malaria and nutrition is not straightforward. This interrelation between malnutrition and malaria is generally viewed as synergistic, although several reports from the past have pointed to the contrary. Early studies showed a protective role of undernutrition [38–41], and recent studies indicate a decrease in malarial illness from nutritional supplementation [42–46]. A better understanding of the interplay between malaria and nutrition will improve our control strategies against this ancient enemy. In this chapter, we will explore the complex linkages between malaria and host nutritional status through a review of relevant studies conducted in animals and humans. MalaRia—Case DefiNitioNs An important and very relevant end point in any clinical malaria study is to look for reduction in clinical episodes of malaria. However, precise defnition of clinical malaria in research studies is diffcult primarily for two reasons: (i) malarial symp- toms are nonspecifc and (ii) the incidence of parasitemia is high in asymptomatic population in endemic areas. The optimal defnition of clinical malaria may differ with the age of the population and the geographical site, which makes it diffcult to compare studies done in areas with different levels of malaria transmission [47–49]. In some studies, malaria has been loosely defned as the mere presence of fever without microscopic confrmation of the malarial parasite. The distinction between mild and severe malaria is also not consistent; however, the case defnition of severe malaria usually encompasses one of the clinical syndromes: i. Quantitative and qualitative changes to host nutritional status can have sig- nifcant infuence on the dynamics of infectious diseases . Pioneering studies by Scrimshaw and several others laid emphasis on the fact that the host nutritional status is as important as the infectious agent in infuencing the course of a disease process [51–53]. Evidence from both animal and human studies has shown that the 228 Nutrition–Infection Interactions and Impacts on Human Health interplay of malaria and malnutrition is complex, and comprehending this complex- ity enhances our understanding of the disease process and implementation of inter- vention strategies. Monkeys and rats fed a protein-restricted diet were noted to have less Plasmodium knowlesi and P. A mechanistic insight on how malnutrition confers protection to malarial infection was suggested in studies of murine malaria. Malarial parasites were shown to infict oxidative damage to infected erythrocytes . It is likely that this oxidant stress is enhanced by the accompanying defciency of antioxidants due to poor nutritional intake. This potentially could lead to enhanced lysis of infected cells, leading to parasite death and protection from the disease . The above phenomenon was complemented by a study where vitamin E-defcient diet exerted a pronounced sup- pressive effect against the malarial parasite . Despite the evidence that protein-restricted animals experienced less malarial morbidity and mortality, infected animals had impaired ability to clear infection , depressed cell-mediated immunity , and a strong relapse reaction . Some studies also showed increased mortality in severely malnourished young rats . Replication of the avian malaria parasite Plasmodium relictum was controlled well in hosts (canaries) who received a supplemented diet (protein and vitamin) and the avian populations exposed to reduced food availability were more susceptible to malaria parasites . Several aspects of these studies had methodological limitations such as lack of healthy control population for compari- son, incomplete data analyses, lack of information on comorbid factors like socio- economic status, and poor description of malnourished status of the study population . Some of the early studies, which were conducted in famine environments, noted an increase in P. It is possible that the biology of the famine-stricken population was different from the nonfamine-afficted population with chronic malnutrition. Studies exploring the association between malaria and growth in humans have shown inconsistent results. Several studies done in Africa indicate that malnutrition pre- disposes to infection [67–70].
