Studies were carried out from June 1974 to May 1975 on the socio-economic status, health and nutritional status of the people in 4 villages, in the irrigation area of the Nong Wai Pioneer Agricultural Project of Khon Kaen Province, Northeast Thailand. The result obtained were compared with those in 2 non-irrigated villages in the same province, in order to identify the health and nutritional problems which might arise during the water resource development in the irrigation area. It was found that in the irrigated villages 90% of the peoples were farmers, while in the non-irrigated villages all were farmers. The socio-economic status of the people in the irrigated villages was much better than those in the non-irrigated ones. The income per family in the former was about three times greater than that in the latter. In the study of the health conditions of the villagers, the vulnerable age group including pre-school children under 7 years of age and school children in the elementary school class 1 and class 2, aged 7-9 years old, served as subjects for investigation. Haematological and physical examinations revealed many children with mild to moderate anaemia, vitamin B2 deficiency and a few cases of hepatomegaly. Anaemic children were found to be more prevalent in the non-irrigated villages than in the irrigated area. The overall parasitic infection rates in children in the irrigated and non-irrigated villages were similar with respect to severity of the infection. Hookworm infection, opisthorchiasis, strongyloidiasis and giardiasis were the leading parasitic infections, while amoebiasis was rare. Ascariasis and trichuriasis were not found. However, the first two helminthic infections had a low grade of intensity. The nutritional status of pre-school children, showed that there were more children with good growth in the irrigated villages than in the non-irrigated one. Serum proteins, albumin and globulin, and urinary urea nitrogen-creatinine ratio revealed normal findings indicating that the children had sufficient protein intake. The results of the urinary hydroxyproline-creatinine index suggested that many of the children in both groups of the villages were at marginal malnutrition status. Surveys on domestic animals including cattle, buffaloes, pigs, and field rats revealed no important zoonotic diseases except leptospirosis in a few rats. Some fish were found to harbour metacercariae of Opisthorchis viverrini, while some snails were positive for cercariae of O. viverrini, Schistosoma spindale, and Echinostoma malayanum. The overall findings indicated that the water resource development by establishing better irrigation, resulted in an improved socio-economic and nutritional status among the villagers, but health conditions and associated parasitic diseases and some nutritional deficiency still existed in the children. However, the findings from this study provide only preliminary data concerning the socio-economic status, health, and nutritional status of the villagers in the irrigation area...

The haematological status, as well as the fractional absorptions of folic acid (FAFol) and vitamin B12 (FAB12) were studied in 29 children aged 0.7-13.5 years (mean 3.3 years) with chronic diarrhoea due to giardiasis. Small intestinal biopsies revealed mucosal damage in 20 children; the biopsies of the remaining nine children were normal. At the initial investigation the FAFol and FAB12 values were below normal in approximately one-sixth and one-third of patients, respectively. Bacterial overgrowth of the small intestinal tract did not seem to play a role in FAB12 malabsorption. About one-fifth of patients had mild anaemia. None of the patients showed FAB12 insufficiency and only one patient suffered from folate depletion. At follow-up, FAFol, FAB12, haemoglobin and Erc-folate concentrations increased significantly while P-B12 and P-folate remained unchanged. Iron status, as well as dietary intake of iron, appeared insufficient prior to, as well as after treatment. Serum iron, transferrin saturation and haemoglobin concentrations were lower in patients who had acquired the disease abroad or suffered from persistent diarrhoea.

To assess the prevalence and species of intestinal parasitoses and to evaluate the effects of parasitic infections on the nutritional health of northeastern Thai children a survey was carried out among 343 urban and rural 3-8-year-olds in Sakon Nakhon province. Approximately 57% suffered from single or multiple helminthiasis (ancylostomiasis (AD), ascariasis (AL), opisthorchiasis (OV) and/or strongyloidiasis (SS)) and/or giardiasis (GL). In rural areas the prevalence of AD and SS was higher than in urban areas (p less than 0.01 and p less than 0.05 respectively). OV was found more frequently among 6-8-year olds (18%) than among 3-5-year olds (5%); among 3-5-year olds the prevalence of GL was higher than among 6-8-year olds (17 vs 8%). Multiple infections were observed in 13% of the children. Infected children showed lower daily intakes of protein, iron and riboflavin as well as lower menas for haemoglobin, haematocrit, serum ferritin, and Z-score height for age than non-infected children. The prevalence of stunted children was lower among non-infected children (32%) than among infected children (53%), and children with AL (49%), SS (55%), and GL (45%). Anaemia was found more frequently among the infected children (59%) and GL-children (61%) than among non-infected children (42%). Inadequate daily intake of energy and nutrients of most of the children, in combination with parasitic infections, still common in rural northeast Thailand, was shown to result in a serious public health problem.

The purpose of the study was determination of the frequency of the association of hypochromic anaemia with infections by Ascaris lumbricoides and Giardia intestinalis. Among 5603 studied patients of either sex, aged 3 to 18 years ascaridiasis alone was diagnosed in 226 children (4%), and giardiasis alone in 106 cases (1.9%). The frequency of this anaemia in these groups ranged from 6% to 16%.

To study the etiology of chronic childhood diarrhea among Nigerian children, 142 patients, aged 6 months to 5 years, with diarrhea for at least 1 month, were evaluated; the study took place during January-December 1983 at the Ahmadu Bello University Teaching Hospital, Zaria, Northern Nigeria. Enteropathogenic agents were identified in stools of 90 (63%) patients. Giardia lamblia and Entamoeba histolytica were most commonly detected, representing 41% and 23%, respectively, of all parasitic pathogens. In children with negative stool microscopy, chronic diarrhea was associated with primary lactose intolerance (2 cases), abdominal tuberculosis (2 cases), hyponatremia, low serum albumin, anemia due to sickle cell disease, or Staphylococcus aureus infection. In contrast with chronic diarrhea etiologies reported among children in Europe and North America, infections were the major cause of chronic childhood diarrhea among these children. In general, it is accepted that intestinal infection usually produces acute diarrhea--and that, if the host fails to mount a competent immune response, if there is repeated exposure to infectious agents, or if severe infection damages a substantial proportion of absorptive cells, then severe, protracted diarrhea may result. The high case fatality rate of 9% in this series was associated with specific infectious complications of septicemia, bronchopneumonia, lobar pneumonia and measles. Severe malnutrition also worsened the prognosis in chronic diarrhea. The results indicate that early detection and treatment of amebiasis and giardiasis is a useful approach in the treatment of chronic diarrhea cases among children.

In Dakar, through histopathological biopsies, the author looked for duodenal alterations in four parasitosis: giardiasis, strongyloidiasis, hookworms and ascaridiosis. He gives an overall survey on malabsorption in relation with intestinal parasitosis, including intestinal capillariosis and coccidiosis. He recalls basic concepts concerning each of these parasitic diseases, with a special mention to mucosal invasion and endogenous self reinfection during some parasitosis; he also emphasizes the importance of some diagnosis techniques (such as examination of duodenal fluid in relation to giardiasis). Anatomical lesions (villi atrophia and chorion cellular infiltration) were the starting point to study such as intestinal malabsorption. But these lesions are neither specific nor regular. Other causes must be determined such as direct action of the parasite, bacterial overgrowth, exudative enteropathy. The role played by host factors seems to be of the utmost importance in giardiasis and strongyloidiasis (antibody deficiency proteinic malnutrition). The part played by the parasite biomass is unquestionable in hookworm disease (hypoalbuminuria, anemia) and a great number of worms in ascaridiasis worsens a preexisting condition of malnutrition. Finally, intestinal parasitosis, with a special mention to giardiasis and strongyliasis, may be responsible for a malabsorption syndrome. They must be identified through reliable diagnosis tests, prior to referring to "idiopathic malabsorption syndrome in Tropical areas".

Biopsy of the liver revealed granulomas in portal tracts and cholangitis in a woman with chronic diarrhea, weight loss, fever, hypoalbuminemia, and anemia attributed to giardiasis. Eradication of Giardia resulted in rapid improvement of symptoms and resolution of histologic changes on a second biopsy of the liver after 3 mo. The patient had serum immunoglobulin levels that were either normal (IgG, IgM) or elevated (IgA), detectable levels in serum of anti-Giardia antibody, and an HLA phenotype (B12, B27) known to be associated with prolonged giardiasis.

The blood concentrations of haemoglobin were investigated in 82 children aged 2-9 years. Fifty-seven (31 boys and 26 girls) were stool-positive for Giardia intestinalis but the other 25, used as controls, were negative. The mean (S.D.) haemoglobin concentration among the infected children was significantly lower pre-treatment than that for the control group [11.6 (1.2) v. 12.6 (1.5) g/dl; P < 0.05]. Treatment of the infected children with a single oral dose of secnidazole (30 mg/kg) led to a significant increase in their mean haemoglobin level 15 days later, from 11.6 (1.2) g/dl pre-treatment to 12.4 (1.2) g/dl post-treatment (P < 0.05). The results indicate that the therapeutic control of giardiasis could be important in programmes to combat anaemia in children living in endemic areas.

The present work is based upon a prospective in study done in a semi-urban area of suburbs of Tunis, from february to November 1997. A total of 302 children aged between 6 month to 5 years were enrolled in the survey. The study aimed at assessing the extention of parasitoses in preschool aged children. The relationship between the Giardiasis intestinalis and ferropenic anemia. The prevalence of anemia is 31.78% (n = 302). The parasitologic analysis has shown that 113 children out of 302 are infected; 37.41%. We observed an obvious predominance of Giardia Lamblia: 62% (n = 113) pathogenic protozoon. The rate of anemia parasited children is amounted to 19.78%. During the Giardiasis, anemia is present in 23.17% of the cases. The Polyparasitism concerns 16% of the infested children. This anemia could be caused by a global bad absorption syndrome or by a ferro-elective bad absorption. A proper sanitary education, a purification action and also a curative treatment of the beaners carriers will be the only guarantees to decrease its morbidity.

A 56 year-old male patient had a gastric resection (Billroth II) at age 33. In 1993 he had vague upper digestive complaints. During investigations for a moderate anaemia biopsies performed during an oesogastroduodenoscopy revealed a jejunitis with Giardia lamblia (G.l.) trophozoites which were also found on the gastric mucosa associated with Helicobacter pylori related chronic active gastritis. The few publications dealing with the presence of Giardia lamblia in the stomach either assert or cast some doubts on the pathogenicity of this protozoa for the gastric mucosa. Gastric involvement by G.l. is usually associated with duodeno-jejunal disease responsible for diarrhoea which may occur as epidemics of varying extension. Since Giardia lamblia infection is not submitted to reporting in Switzerland, the epidemiology in our country is scarcely known and investigated. In our opinion, however, health authorities in Switzerland should consider the need of reporting this infectious disease.
