RESUMO
OBJECTIVES: For decades, Niger, a Sahelian country in Africa, has faced serious food and nutrition crises. Policies and strategies have been implemented by the Government, with the support of its partners, to address this public health problem. The current study was conducted to assess trends in malnutrition among children under 5 years of age. By comparing results from 2008 to 2014 with results from 2015 to 2021, this study aimed to check the efficacy of strategies and policies that were implemented to combat malnutrition. STUDY DESIGN: Retrospective study. METHODS: Data from the annual nutrition survey Standardized Monitoring and Assessment of Relief and Transitions and the Demographic and Health and Multiple Indicator Surveys were used. Meta-analyses were performed on the data as a whole and in each age group by time period. For analysis of age groups, the 95% confidence interval (CI) data were missing, thus an estimate was made from the 'design effect' calculated based on existing CIs. RESULTS: Institutional arrangements had not changed from 2008 to 2014 to 2015-2021, and there were very few changes to existing strategies and policies. The prevalence of Global Acute Malnutrition and Global Chronic Malnutrition (GCM) both remained above critical thresholds for each year in both periods. GCM was above the emergency threshold for both periods, indicating that all regions of the country were affected by malnutrition. The most populated regions (40%) of Maradi and Zinder were the most affected by malnutrition. These two regions also had highest incidence of poverty and the least health service coverage. CONCLUSIONS: Despite the implementation of various policies and strategies, the nutritional status of children under 5 remains an important public health problem.

BACKGROUND: Despite numerous advantages of breastfeeding, in Democratic Republic of the Congo, the rate of children exclusively breastfed up to six months remains low. The lack of breastfeeding support received by mothers from health care providers is an important factor of early cessation of breastfeeding. This study aimed to evaluate the effect of the training of health care providers, in the Baby Friendly Hospital Initiative, on the duration of exclusive breastfeeding (EBF) in Kinshasa. METHODS: A total of 422 mothers, recruited during the first antenatal care visit in 12 maternities and followed up to six months after delivery, were included in a cluster randomized trial. In the experimental group, health care providers were trained using the "20-Hour Course For Maternity Staff". Cox proportional hazards model was used to determine the effect of the intervention on the duration of EBF. RESULTS: The rate of EBF at six months was 2.8%; the median duration of EBF was 10.9 weeks (IQR 4.3 to 14.9). The hazard of discontinuing EBF before six month was 1.4 times higher in the control group (adjusted HR [95%CI]=1.40 (1.10-1.78), P=0.007). CONCLUSION: In this study, training of health care providers in the Baby Friendly Hospital Initiative was associated with a significant improvement in the duration of EBF. Extending this training to different maternities could improve the coverage of EBF in Kinshasa.

BACKGROUND: The present study was initiated in order to determine the rate, the causes and the risk factors for perinatal mortality in Lubumbashi, Democratic Republic of Congo. METHODS: Data for this cross-sectional study were collected by interviewing participating women and by analysis of medical files. Women who gave birth in 2010 and were residents of Lubumbashi during the same year were included.Women were included irrespective of the pregnancy outcome and perinatal survival was determined for newborns aged at least seven days.Women were recruited from households selected by cluster sampling for healthcare zones. Perinatal mortality was defined as stillbirths and early neonatal deaths per 1000 births. Risk factors were sought using the odds ratio method adjusted by logistic regression using a 5% threshold. RESULTS: Among 11,536 surveyed women, there were 11,633 births including 177 stillbirths and 133 early neonatal deaths. Perinatal mortality was 27% (95%IC = 23.729.6%). The causes of this mortality were respiratory distress (58.2%), neonatal infection (pneumonia and neonatal meningitis, 13.5%), complications of prematurity (9.0%), neonatal tetanus (1.6%), congenital malformations (0.6%). The cause of perinatal death was unknown for 17.1%. Risk factors for perinatal mortality were: unmarried mother; home delivery; complicated delivery; dystocia; caesareansection; multiple pregnancy; low birth weight; prematurity. CONCLUSION: Action should be taken to improve availability, use and quality of Emergency obstetrical and neonatal care. Women should be better informed concerning the danger signs of pregnancy and childbirth.

BACKGROUND: Although HIV testing is offered during antenatal care, the proportion of women giving birth without knowing their HIV status is still important in DR Congo. The objective of this study was to determine the acceptability of rapid HIV testing among parturients in labor room, and to identify factors that are associated with the acceptability of HIV testing. METHODS: Intervention including rapid HIV testing among pregnant women in labor rooms in Lubumbashi for 5 months, from September 2010 to February 2011. Pregnant women who tested HIV positive were attended by prevention of mother-to-child transmission service. Descriptive statistical analysis and logistic regression were performed. RESULTS: Among 474 pregnant women who enter the labor room, 433 (91.4%; confidence interval [CI]: 95%: 88.4-93.7%) had voluntary testing for HIV in the labor room after counseling. The acceptance of rapid testing for HIV was significantly higher when the duration of counseling was less or equal to 5 minutes (adjusted Odds ratio [aOR]=5.8; [CI] 95%: 2.6-13); among those who did not report having this screening test during antenatal care (aOR=3.8; [CI] 95%: 2-7.8), among those who were in early labor (aOR=2.3; [CI] 95%: 1.2-4.7) and lower in adolescents than in adults (aOR=0.1; [CI] 95%: 0.0-0.7). CONCLUSION: Counseling and voluntary HIV testing are accepted in our labor rooms. Consistently offering this service in the labor room could be a catch-up strategy to be combined with antenatal care testing.

BACKGROUND: Despite a reduction in the magnitude of endemic malaria reported in recent years, malaria and protein-energy malnutrition (PEM) still remain major causes of morbidity and mortality in sub-Saharan Africa among children under five. The relationship between malaria and malnutrition remains a topic of controversy. We aimed to investigate malaria infection according to nutritional status in a community-based survey. METHODS: A cohort of 790 children aged 6 to 59 months and residing in eastern Democratic Republic of the Congo was followed-up from April 2009 to March 2010 with monthly visits. Data on nutritional status, morbidity between visits, use of insecticide-treated nets and malaria parasitemia were collected at each visit. The Z scores height for age, weight for age and weight for height were computed using the reference population defined by the WHO in 2006. Thresholds for Z scores were defined at -3 and -2. A binary logistic model of the generalized estimating equation (GEE) was used to quantify the association between PEM indicators and malaria parasitemia. Odds ratio (OR) and their 95% confidence interval (95% CI) were computed. RESULTS: After adjustment for season, children with severe stunting (height for age Z score<-3) were at lower risk of malaria parasitemia greater or equal to 5000 trophozoits/µL of blood as compared to those in with a better nutritional status (height for age Z score≥-2) (OR=0.48, 95% CI: 0.25-0.91). CONCLUSION: Severely stunted children are at a lower risk of high-level malaria parasitemia.

BACKGROUND: The aim of this study is to establish factors explaining perinatal death rates in the city of Lubumbashi. METHODS: We have carried out a case controlled study in the maternity ward of Jason Sendwe hospital. Perinatal death cases have been compared to those of surviving newborn children among parturient women in the course of 2008. Sociodemographic characteristics, maternal morbidity, children's typical features, have been studied as independent variables. Their effect on perinatal mortality has been assessed using an adjusted odds ratio value at a 5% confidence interval and a logistic regression model. RESULTS: In total, we considered 2279 births (mother and child pairs) for our study. Among these were 415 perinatal mortality cases and 1864 control cases. After adjustment for several parameters, household chores (AOR=1.8; 95% IC=1.2-2.9), multiple pregnancies (AOR=1.9; 95% IC=1.2-2.9), malaria (AOR=1.4; 95% IC=1.1-1.8), primiparity (AOR=1.7; 95% IC=1.3-2.4), stillbirth (AOR=5.2; 95% IC=2.5-11.0) and prematurity (AOR=2.9; 95% IC=1.5-5.5) in previous pregnancies, onset of antepartum ferver (AOR=3.0; 95% IC=1.2-7.3) and antepartum hemorrhage (AOR=6.8; 95% IC=3.1-15.0), lack of fetal motions near delivering time, dystocias (AOR=2.0; 95% IC=1.3-3.0), low birthweight (AOR=15.7; 95% IC=11.2-22.0), very low birthweight (AOR=49.0; 95% IC=28.6-85.1) and foetal macrosomia (AOR=3.5; 95% IC=1.8-7.0) were the main factors explaining perinatal mortality. CONCLUSION: Perinatal mortality in Lubumbashi remains associated with several avoidable factors. Basic and emergency obstetrical-neonatal care (B-EMONC) should be improved. Significant efforts should be made in this direction. Perinatal audits should be established for a good heath care quality follow-up. Obstetrical care should be offered as a continuum in order to facilitate communication between the different caregivers.

BACKGROUND: Recent estimates of the role of malnutrition on childhood mortality have led to a call for action by decision makers in the fight against child malnutrition. Further evaluation is needed to assess the burden of malnutrition in terms of morbidity and mortality, as well as to assess the impact of various interventions. The objective of this study is to determine the effect of malnutrition on mortality in a pediatric service of a rural hospital in Rwanda. METHODS: A prospective cohort study included children aged 6-59 months coming from the catchment area of the hospital and admitted to the pediatric ward between January 2008 and June 2009. Anthropometric, clinical and biological data were gathered at the time of admission. The effect of malnutrition at the time of admission on mortality during hospitalization was analyzed by using logistic regression. RESULTS: At the time of admission, the prevalences of wasting, underweight and stunting among children was 14.2%, 37.5% and 57.3% respectively. Fifty-six children died during hospitalization. The period mortality rate was 6.9%. After adjustment for age, sex, malaria thick smear and breathing with chest retractions, death was associated with underweight and stunting with adjusted odds rations of 4.6 (IC95% 2.5-8.4) and 4.0 (IC95% 2.0-8.2) respectively. CONCLUSION: The study confirmed the influence of malnutrition on child mortality in pediatrics wards. These results can be of great help for improving the awareness of the community decision-makers in the fight to prevent malnutrition.

BACKGROUND: In order to improve the management of a community based nutrition program in the catchment area of Ruli District Hospital in Rwanda, we carried out a nutrition survey to determine the risk factors for childhood malnutrition in the area. Identifying the groups of children at risk of malnutrition and their risk factors allows the community nutrition workers to target the children who require close monitoring, and assists in the development of key messages for educational nutrition training. METHODS: The prevalence of the three forms of malnutrition was estimated by using the Z-scores height for age, weight for age and weight for height with NCHS/OMS/2000 reference. Logistic regression was performed to identify the risk factors for malnutrition. RESULTS: Our findings show that children from 12-35 months of age are at greatest risk of malnutrition. Risk factors for wasting include: low monthly income of the household, concurrent illness of the child and a household that does not practice breeding. Risk factors for underweight include: child being greater than 12 months of age, mother of the child being pregnant and history of malnutrition in the household. Finally, risk factors for stunting include the absence of a mosquito net in the household, an insufficient number of working adults in the household, the child being greater than 12 months of age and a household managed by a man alone or by an orphan. CONCLUSION: Community based growth monitoring must focus its attention on the children from nine to 35 months of age. Children less than nine months of age are generally followed by the health centers through the immunization program, and the older children are generally followed in the child minder schools that need to be promoted in all the cells. Community messages must focus on the identified risk factors of malnutrition, and a positive deviance approach must be introduced in the entire zone.

BACKGROUND: In Rwanda, the community-based growth-monitoring program is implemented via volunteer community nutrition workers. These volunteers are recruited from within their communities, and receive basic training prior to providing services. Utilizing local volunteers improves access to basic nutrition services, and allows the local health jurisdictions to use qualified health care staff more efficiently. In addition to concerns raised in regards to the accountability of unpaid workers, some question the relevance of the data that is collected. We carried out a nutritional survey in the catchment area of Ruli District Hospital to evaluate the reliability of the community nutrition workers' measurements of anthropometric standards collected within the growth-monitoring framework. METHODS: A nutritional survey was recently organized in the catchment area of the hospital in December 2006. The prevalence rates of malnutrition from the survey were compared with those from the existing community-based growth-monitoring program. Z-test was used to compare the prevalence rate of underweight from the survey with the prevalence rate determined by data collected from community nutrition workers. The concordance of children classified with moderate and severe underweight in each data set was determined by the coefficient Kappa of Cohen. RESULTS: Our findings show that the recent survey reported an overall underweight prevalence rate of 27.2%. Community data calculated a prevalence rate of 28.8% for the same population. The difference is not statistically significant (P=0.294). Of 724 children evaluated, the survey and the community were in agreement in regards to 454 children classified in the category of good nutritional status, 143 children classified in moderate underweight and 11 children classified in the severe underweight category. The Kappa of Cohen coefficient of 0.636 indicates strong concordance between data sets. CONCLUSION: Anthropometric measurements provided by the community are reliable. Information gathered from the community can be used for epidemiologic monitoring of malnutrition. To ensure continued reliability, health centers must provide sufficient and permanent training to community nutrition workers. In addition, continued access to essential materials used for measuring nutritional status and maintenance of these materials will be crucial to the program's ongoing success.

The study assessed the ability of community volunteers, working with district health officials, to conduct a local census to count the population in their villages and assess their nutritional vulnerability. The study involved organizing community volunteers in village nutrition committee and assigning them to count the village population in a Kivu rural health district (D.R.Congo) and assess their vulnerability in terms of nutrition. The study took place in March and April 2003, during armed conflict in the region. Community volunteers supervised by district health officials collected data, presented here as median proportions (with their Max and Min), by age category. The results show that community volunteers were able to conduct this census with reliable results. The population distribution by age category was similar to the national model from a survey by experts. The community volunteers estimated a median of 22.2 % (6.2-100 %) of households in each village in the eastern DR Congo were vulnerable and required foreign aid. Community volunteers can contribute accurately to the collection of demographic data to be used in health programme planning, thus allowing these data to be followed even during instability and armed conflicts.

BACKGROUND: To evaluate the impact of spiruline on nutritional rehabilitation. DATA SOURCES: Systematic search in medical and scientific databases (Medline, Cochrane, Embase) and other specific databases (PhD theses, reports...). METHODS: We selected studies in which spiruline was used as supplementation in malnourished patients, irrespective of the form and dose of spiruline and in controlled trials or not. Two persons made the selection separately. Nutritional status was estimated by anthropometric and biological measures. RESULTS: Thirty-one references were identified and seven studies were retained for this review; three randomized controlled and four non-controlled trials. Spiruline had a positive impact on weight in all studies. In non-controlled trials, the other parameters: arm circumference, height, albumin, prealbumin, protein and hemoglobin improved after spiruline supplementation. For these studies, methodology was the main drawback. None of the studies retained for analysis were double-blinded clinical trials and all involved small samples. Four of them did not have a control group for comparison. CONCLUSION: The impact of spiruline was positive for most of the considered variables. However, the studies taken into account in this review are of poor-methodological quality. A randomized, a large-sized double-blind controlled clinical trial with a longer follow-up should be conducted to improve current knowledge on the potential impact of spiruline on nutritional rehabilitation.

In the Kivu region located in east of the Democratic Republic of the Congo, malnutrition and malaria is a major cause of morbidity and mortality. The relationship between malaria and malnutrition is unclear and has never been studied in the Kivu region. This report presents an analysis of data from 5695 children aged 0 to 5 years, admitted to the paediatric ward of Lwiro hospital between November 1992 and February 2004. The weight/age (W/A) index and weight/height (W/H) index expressed with standard deviation in relation to the reference median were calculated (Z score). The association between protein-energetic malnutrition and malaria infection and nutritional indicators was measured based on prevalence ratios determined by univariate analysis and adjusted Odds Ratio (OR) derived using a multivariate model. The prevalence of malaria at the time of admission was 35.8 % (n=5695). The W/A and W/H indexes and serum albumin level were correlated with malaria-related morbidity. Logistic regression showed that high malaria OR was associated with both anthropometric nutritional indicators [WHZ > -2: OR (CI 95 %) 1.7 (1.4-2.2)] [WAZ > -2: OR (CI 95 %) 1.3 (1.1-1.6)] and biological nutritional indicators [serum albumin > or = 23 g/L: OR (CI 95 %) 1.6 (1.2-2.1)]. Our findings indicate that malnourished children at admission have a lower risk of malaria infection.

BACKGROUND: In vitamin A-deficient populations, children hospitalized with infections and/or malnutrition are at particular risk of developing severe vitamin A (VA) deficiency. High-dose VA supplements are recommended as part of the treatment but results on its effect on recovery from morbidity and on prevention from nosocomial morbidity are conflicting. OBJECTIVE: We aimed to assess the effect of a single high dose and daily low dose of VA on hospitalized malnourished children's morbidity. DESIGN: We carried out a double-blind, randomized trial in 604 and 610 Senegalese hospitalized children. The first mentioned batch received a high-dose VA supplement (200,000 IU) on admission, the second a daily low-dose VA supplement (5000 IU per day) during hospitalization. Children were followed up until discharged. Data on all-cause morbidity were collected daily. RESULTS: Survival analysis showed that the incidence of respiratory disease was significantly lower in the low-dose group than in the high-dose group, hazard ratios (HR): 0.26, 95% CI: 0.07-0.92. The duration of respiratory infection was also significantly lower in the low-dose group than in the high-dose group (HR of cure: 1.41, 95% CI: 1.05-1.89). Duration and incidence of diarrhoea were not significantly different between treatment groups. In children with oedema on admission, mortality was significantly lower in the low-dose group (Adjusted odds ratio: 0.21; 95% CI: 0.05-0.99). CONCLUSIONS: Daily low dose of VA compared with single high dose significantly reduced duration and incidence of respiratory infection but not of diarrhoea in hospitalized children.

BACKGROUND: Management of acute severe malnutrition greatly contributes to the reduction of childhood mortality rate. In developing countries, where malnutrition is common, number of acute severe malnutrition cases exceeds inpatient treatment capacity. Recent success of community-based therapeutic care put back on agenda the management of acute severe malnutrition. We analysed key issues of inpatient management of severe malnutrition to suggest appropriate global approach. METHODS: Data of 1322 malnourished children, admitted in an urban nutritional rehabilitation center, in Burkina Faso, from 1999 to 2003 were analyzed. The nutritional status was assessed using anthropometrics indexes. Association between mortality and variables was measured by relative risks. Kaplan-Meier survival curves and Cox model were used. RESULTS: From the 1322 hospitalized children, 8.5% dropped out. Daily weight gain was 10.18 (+/-7.05) g/kg/d. Among hospitalized malnourished children, 16% died. Patients were at high risk of early death, as 80% of deaths occurred during the first week. The risk of dying was highest among the severely malnourished: weight-for-height<-4 standard deviation (SD), RR=2.55 P<0,001; low MUAC-for-age, RR=2.05 P<0.001. Kaplan-Meier survival curves and Cox model showed that the variables most strongly associated with mortality were weight-for-height and MUAC-for-age. Among children discharged from the nutritional rehabilitation centre, 10.9% had weight-for-height<-3 SD. CONCLUSION: The nutrition rehabilitation centre is confronted with extremely ill children with high risk of death. There is need to support those units for appropriate management of acute severe malnutrition. It is also important to implement community-based therapeutic care for management of children still malnourished at discharge from nutritional rehabilitation centre. These programs will contribute to reduce mortality rate and number of severely malnourished children attending inpatient nutrition rehabilitation centers, by prevention and early management.

BACKGROUND: Malaria is a major health problem in tropical Africa. In DRC, little is known about the characteristics of households of children with severe malaria or the factors associated with its lethality, especially relative to hospital status. METHODS: This study of 9 hospitals of the city-province of Kinshasa studied 1350 children younger than 15 years and hospitalized for severe malaria from January to November 2011. RESULTS: More than three quarters of children admitted to public (state) and church hospitals were from poor households and with uneducated mothers (P < 0.001). The case-fatality rate (5.9% of all children) differed according to hospital status: 5.3% in state hospitals, 8.4% in private hospitals, and 4.0% in the faith-based hospitals (P < 0.001). The risk of death was significantly associated with circulatory collapse (odds ratio, OR = 10.3), number of associated syndromes >2 (OR = 3.5), z-score of weight-for-age ≤-2 (OR = 3.5), delay in seeking medical care (OR = 4.9), body temperature ≥40°C (OR = 2.9), respiratory distress (OR = 1.9) and home rental (versus ownership) a tenant (OR = 2.8), and anorexia was a protective factor (odds ratio = 0.5). CONCLUSION: Severe cases of malaria are rife in poor households and periurban residential areas. Orienting prevention, control, and care- according to the vulnerability of affected households and providing early treatment are imperative if we are to reduce mortality from malaria.

The effect of high-dose vitamin A supplementation on recovery from morbidity and on recovery from nosocomial morbidity of hospitalized children has been poorly studied and results are conflicting. The effect of daily, low doses has never been assessed. We investigated the effect of a single high dose and daily, low doses of vitamin A on diarrhea, acute lower respiratory tract infections (ALRIs), and all-cause fevers in 900 hospitalized preschool-age children in the Democratic Republic of Congo in a randomized, double-blind, placebo-controlled clinical trial. The high-dose treatment group received 200,000 IU vitamin A (100,000 IU if aged <12 mo) orally on the day of admission, the low-dose treatment group received 5000 IU vitamin A/d until discharge. Data on all-cause morbidity were collected daily. Mortality rates were not significantly different among the 3 groups. High-dose vitamin A supplementation had no significant effect on the duration of moderate or severe diarrhea nor on the duration and incidence of ALRIs and all-cause fevers. Children in the high-dose group with no edema had an increased risk of severe nosocomial diarrhea (relative risk: 2.42; 95% CI: 1.15, 5.11). Low-dose vitamin A supplementation significantly reduced the incidence of severe diarrhea in severely malnourished children (relative risk: 0.21; 95% CI: 0.07, 0.62) but showed no significant effect on the duration of moderate or severe diarrhea or on the duration and incidence of ALRIs and all-cause fevers. Supplementation with high doses of vitamin A did not reduce morbidity in this population of malnourished and subclinically vitamin A-deficient children; daily, low doses appeared more beneficial for severely malnourished children.

OBJECTIVE: To assess the usefulness of the molar ratio of serum retinol-binding protein (RBP) to transthyretin (TTR) to determine vitamin A (VA) status during infection. DESIGN: We took advantage of previously collected data during a randomised double-blind, placebo-controlled clinical trial to conduct a secondary analysis of the RBP/TTR ratio and its relationship to infection and VA status. In this clinical trial, children were randomly assigned to one of three groups and received either one single oral high dose of VA (200 000 IU) on the day of admission and subsequently a placebo daily until discharge or daily oral low doses of VA (5000 IU) from admission until discharge or a placebo daily from admission until discharge. SETTING: Lwiro pediatric hospital, Province of South Kivu, Democratic Republic of Congo. SUBJECTS: A total of 900 children aged 0-72 months hospitalised consecutively between March 1994 and March 1996. MAIN OUTCOME MEASURES: RBP/TTR molar ratio after 7 days hospitalisation. RESULTS: After 7 days hospitalisation, molar RBP:TTR ratio (mean+/-s.d.) of infected children (C-reactive proteins>10 mg/l) was 0.67+/-0.31 in the high-dose group (n=81), 0.74+/-0.44 in the low dose group (n=71) and 0.73+/-0.39 in the placebo group (n=81). These values did not differ significantly (one-way ANOVA P=0.472). In patients with baseline serum retinol concentrations<0.70 micromol/l, changes in RBP:TTR ratio between admission and day 7 were not statistically different in the three groups (one-way ANOVA P=0.548). CONCLUSIONS: In this population of malnourished hospitalised children, molar RBP:TTR ratio does not appear to be useful to assess VA status during infection. SPONSORSHIP: Our research was partially supported by a grant from the Fonds de la Recherche Scientifique et Médicale (contract 3.4505.94) and the David and Alice Van Buuren Foundation.

OBJECTIVE: To assess pre-school age children's vitamin A status in a population where protein-energy malnutrition is endemic and serum retinol binding protein and transtyretin concentrations are low. DESIGN: A cross-sectional study. SETTING: Health district of Katana, South-Kivu, Zaire. SUBJECTS: 415 pre-school age children. METHODS: Three methods were used to assess vitamin A status: ophtalmological examination, retinol serum concentration and Relative Dose Response (RDR) test. RESULTS: The only ophthalmological signs of vitamin A deficiency appeared in two cases of night blindness, which represents a prevalence of 0.7%. Deficient serum retinol concentration (< 0.35 mumol/l) was found in 19.7% of the whole study population and in 10.4% of non-infected children in good nutritional status. RDR test carried out on a reduced sample of 79 subjects was abnormal for 7.6% of the children but showed a low sensitivity when compared with serum retinol concentration. CONCLUSION: This survey suggests that in this population of the South-Kivu Province in Zaire, vitamin A deficiency co-exists with protein-energy malnutrition and is a public health problem even with non-malnourished and non-infected children.

OBJECTIVE: To describe the epidemiology of community-acquired bacteremia in children admitted to a rural hospital in central Africa and to identify useful diagnostic signs or symptoms. METHODS: On admission, a blood culture was obtained from all children admitted to Children's Hospital of Lwiro between 1989 and 1990. Clinical and biologic signs of infection and nutritional status were recorded. RESULTS: Among the 779 children included in the study, 15.9% were bacteremic on admission. The rate of bacteremia was the highest among children with jaundice (20/56; 35.7%) and fever (119/487; 24.4%). In contrast, children with severe malnutrition had a lower rate of bacteremia (13.2%) than weight growth retarded or well-nourished children (19.5%) (P = 0.046). Fever was the most useful diagnostic criteria (sensitivity and negative predictive value of 96.0% and 97.8%, respectively) even in severely malnourished children (sensitivity and negative predictive value of 96.4% and 99.1%, respectively). Enterobacteriacea, mostly Salmonella spp, caused 73% of the bacteremia. There was a high rate of resistance to ampicillin and chloramphenicol among the responsible organisms. Only 31 (47.7%) of 65 bacteremic children responded to the combination of ampicillin and gentamicin. The presence of bacteremia on admission did not significantly increase the risk of morality during hospitalization (19.4% compared with 13.5%; P = 0.088). Age less than 12 months and jaundice were independent risk factors for deaths in bacteremic children. CONCLUSIONS: Community-acquired bacteremia caused by multiresistant Enterobacteriacea is an important problem of hospitalized well-nourished and malnourished children in central Africa. Fever on admission is a sensitive diagnostic sign, even in malnourished children.

PIP: Results of a series of historical and recent studies of human milk and its protective antibodies against several bacterial and viral diseases and infantile diarrhea are presented. First, 1476 infants from Lahore, Pakistan from 3 socioeconomic groups, were observed and 300 mothers were given instruction on exclusive breast feeding. The prevalence of diarrhea indicated 60-80% protection to consistency of breast feeding, especially in summer when mothers replace breast milk with other liquids. Historically, secretory immunoglobulins (S-IgA) were first isolated from human milk, traced to intestinal antigen exposure, and local production in gut lymph nodes, from which lymphocytes migrate to the breast to secrete antibodies in milk. Specific S-IgA have been shown against Vibrio cholerae and the ETEC E. coli in milk. It is interesting that parental vaccination of a mother will boost milk IgA, but oral exposure stimulates serum antibodies more than milk IgA. Vaccination of mothers will whole cell cholera vaccine booster titers, but not avidities of S-IgA in milk. Avidities of S-IgA were higher in milk secreted for premature infants and in colostrum than in mature milk. Other research demonstrated that breast-fed infants were better able to mount their own antibody response to diphtheria, tetanus, and polio, as measured in their fecal, salivary, and serum antibodies. Breast feeding is advocated to improve infant survival, and thereby to decrease population growth.^ieng
