Arm circumference for age, arm circumference and weight-for-height z-score for the evaluation of severe acute malnutrition: a retrospective cohort study in eastern Democratic Republic of Congo.

BACKGROUND: Little is known about the use of mid-upper arm circumference for age (MUACZ) for diagnosing of severe acute malnutrition (SAM) and its correlation with WHZ (weight-for-height Z-score) in an area endemic for severe acute malnutrition (SAM) and with a high prevalence of kwashiorkor. Our study aims to analyze the concordance between the diagnostic criteria of SAM in a region presenting these characteristics. METHODS: We analyzed a database of children admitted from 1987 to 2008 for the management of SAM in Eastern Democratic Republic of Congo. Anthropometric indicators (z-score) were calculated and classified into 3 categories according to WHO standards. Cohen's kappa coefficient (κ) was calculated to assess the concordance between these indicators. RESULTS: Out of the 9969 selected children aged 6 to 59 months, 30.2% had nutritional edema, 70.1% had a height-for-age (HAZ) z-score <-2, 11.5% WHZ<-3 z-score, 14.9% had a MUAC < 115 mm and 21.8% had a MUACZ <-3 z-score. With the classic combination WHZ and MUAC, 36% of children with SAM had both criteria at the same time and MUAC alone being the indicator that recruited more children with SAM (77%) compared with 65% with WHZ only. By replacing MUAC with MUACZ, 34% of SAM children fulfilled both criteria, WHZ and MUACZ. MUACZ alone recruited more children with SAM (88%) compared with 46% with WHZ alone. Considering these three indicators together, MUACZ remained the indicator that recruited more children with SAM (85%). WHZ and MUAC showed a moderate agreement [ κ (95% CI) = 0.408(0.392-0.424)], WHZ and MUACZ a weak agreement [ κ (95% CI) = 0.363(0.347-0.379)] and MUAC and MUACZ a good agreement [ κ (95% CI) = 0.604 (0.590-0.618)]. CONCLUSION: Adjusting MUAC according to age improves its effectiveness in identifying severe acute malnutrition. With low concordance, MUAC and WHZ remain complementary in our context. MUACZ proves to be crucial, especially in the presence of kwashiorkor and chronic malnutrition, becoming a valuable tool for assessing severe acute malnutrition in our context.

Association between diagnostic criteria for severe acute malnutrition and hospital mortality in children aged 6-59 months in the eastern Democratic Republic of Congo: the Lwiro cohort study.

Background: Few studies have assessed the relationship between weight-for-height (WHZ) and mid-upper arm circumference (MUAC) with hospital mortality considering confounders. The particularity of MUAC for age (MUACZ) is less documented. Objective: This study aims to investigate this relationship in a region endemic for severe acute malnutrition (SAM). Methods: This is a retrospective cohort based on a database of children admitted from 1987 to 2008 in South Kivu, eastern DRC. Our outcome was hospital mortality. To estimate the strength of the association between mortality and nutritional indices, the relative risk (RR) with its 95% confidence interval (95% CI) was calculated. In addition to univariate analyses, we constructed multivariate models from binomial regression. Results: A total of 9,969 children aged 6 to 59 months were selected with a median age of 23 months. 40.9% had SAM (according to the criteria WHZ < -3 and/or MUAC<115 mm and/or the presence of nutritional edema) including 30.2% with nutritional edema and 35.2% had both SAM and chronic malnutrition. The overall hospital mortality was 8.0% and was higher at the beginning of data collection (17.9% in 1987). In univariate analyses, children with a WHZ < -3 had a risk almost 3 times higher of dying than children without SAM. WHZ was more associated with in-hospital mortality than MUAC or MUACZ. Multivariate models confirmed the univariate results. The risk of death was also increased by the presence of edema. Conclusion: In our study, WHZ was the indicator more associated with hospital death compared with MUAC or MUACZ. As such, we recommend that all criteria shall continue to be used for admission to therapeutic SAM programs. Efforts should be encouraged to find simple tools allowing the community to accurately measure WHZ and MUACZ.

Probiotics for children with uncomplicated severe acute malnutrition (PruSAM study): A randomized controlled trial in the Democratic Republic of Congo.

BACKGROUND: Severe acute malnutrition (SAM) contributes to nearly 1 million deaths annually worldwide, with diarrhea and pneumonia being the common morbidity associated with mortality. OBJECTIVES: To assess the effect of probiotics on diarrhea, pneumonia, and nutritional recovery in children with uncomplicated SAM. METHODS: A randomized, double-blind, placebo-controlled study was conducted involving 400 children with uncomplicated SAM randomly assigned to ready-to-use therapeutic food (RUTF) either with (n = 200) or without (n = 200) probiotics. Patients received 1 mL daily dose of a blend of Lacticasebacillus rhamnosus GG and Limosilactobacillus reuteri DSM 17938 (dosage, 2 billion colony-forming units; 50:50) or placebo during 1 mo. They were simultaneously fed with the RUTF for 6 to 12 wk, depending on patients' recovery rates. The primary outcome was the duration of diarrhea. Secondary outcomes included diarrheal and pneumonic incidence, nutritional recovery, and transfer to inpatient care rate. RESULTS: For children with diarrhea, the number of days of disease was lower in the probiotic group (4.11; 95% CI: 3.37, 4.51) than that in the placebo group (6.68; 95% CI: 6.26, 7.13; P < 0.001). For children aged 16 mo or older, the risk of diarrhea was lower in the probiotic group (75.6%; 95% CI: 66.2, 82.9) than that in the placebo group (95.0%; 95% CI: 88.2, 97.9; P < 0.001), but no significant difference of the risk for the youngest. In the probiotic group, nutritional recovery happened earlier: at the 6th wk, 40.6% of the infants were waiting for nutritional recovery, contrasting with 68.7% of infants in the placebo group; but the nutritional recovery rate at the 12th wk was similar between the groups. Probiotics had no effect on pneumonic incidence and transfer to inpatient care. CONCLUSIONS: This trial supports using probiotics for the treatment of children with uncomplicated SAM. Its effect on diarrhea could positively affect nutritional programs in resource-limited settings. This trial was registered https://pactr.samrc.ac.za as PACTR202108842939734.

Minimum acceptable diet among children aged 6-23 months in South Kivu, Democratic Republic of Congo: a community-based cross-sectional study.

BACKGROUND: Suboptimal child nutrition remains the main factor underlying child undernutrition in Democratic Republic of Congo (DRC). This study aimed to assess the prevalence of minimum acceptable diet and associated factors among children aged 6-23 months old. METHODS: Community-based cross-sectional study including 742 mothers with children aged 6-23 months old was conducted in 2 Health Zones of South Kivu, Eastern DRC. WHO indicators of Infant and Young Child Feeding (IYCF) regarding complementary feeding practices were used. Logistic regression analysis was used to quantify the association between sociodemographic indicators and adequate minimum acceptable diet for both univariate and multivariate analysis. RESULTS: Overall, 33% of infants had minimum acceptable diet. After controlling for a wide range of covariates, residence urban area (AOR 2.39; 95% CI 1.43, 3.85), attendance postnatal care (AOR 1.68; 95% CI 1.12, 2.97), education status of mother (AOR 1.83; 95% CI 1.20, 2.77) and household socioeconomic status (AOR 1.72; 95% CI 1.14, 2.59) were factors positively associated with minimum acceptable diet. CONCLUSION: Actions targeting these factors are expected to improve infant feeding practices in South Kivu.

Etiology of Early-Onset Neonatal Sepsis and Antibiotic Resistance in Bukavu, Democratic Republic of the Congo.

BACKGROUND: The Democratic Republic of the Congo (DRC) has one of the highest neonatal death rates (between 14% and 28%) in the world. In the DRC, neonatal sepsis causes 15.6% of this mortality, but data on the bacterial etiology and associated drug susceptibility are lacking. METHODS: Hemocultures of 150 neonates with possible early-onset neonatal sepsis (pEOS) were obtained at the Hôpital Provincial Général de Référence de Bukavu (Bukavu, DRC). The newborns with pEOS received an empirical first-line antimicrobial treatment (ampicillin, cefotaxime, and gentamicin) based on the synopsis of international guidelines for the management of EOS that are in line with World Health Organization (WHO) recommendations. Isolates were identified using matrix-assisted laser desorption/ ionization time-of-flight mass spectrophotometry. Antibiotic resistance was assessed using the disk diffusion method. RESULTS: Fifty strains were obtained from 48 patients and identified. The 3 most prevalent species were Enterobacter cloacae complex (42%), Klebsiella pneumoniae (18%), and Serratia marcescens (12%). Enterobacter cloacae isolates were resistant to all first-line antibiotics. All K. pneumoniae and S. marcescens isolates were resistant to ampicillin, and the majority of the K. pneumoniae and half of the S. marcescens isolates were resistant to both cefotaxime and gentamicin. All E. cloacae complex strains, 89% of K. pneumoniae, and half of S. marcescens had an extended-spectrum ß-lactamase phenotype. CONCLUSIONS: The most prevalent pathogens causing EOS in Bukavu were E. cloacae complex, K. pneumoniae, and S. marcescens. Most of these isolates were resistant to the WHO-recommended antibiotics.

Effects of probiotics and synbiotics on diarrhea in undernourished children: Systematic review with meta-analysis.

BACKGROUND: Undernutrition predisposes children to a greater incidence and duration of diarrhea. No review and meta-analysis have yet been conducted to assess effectiveness of probiotics and synbiotics in undernourished children. AIMS: To assess the effectiveness of probiotics and synbiotics on diarrhea in undernourished children. METHODS: Randomized, double-blind, placebo-controlled trials evaluating the effects of probiotics and synbiotics on diarrhea in undernourished children were searched from 1990 to May 2020. Recommendations of the Cochrane Handbook and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement were followed. RESULTS: The systematic review identified 15 trials with 6986 patients. The meta-analysis revealed that treatment with probiotic or synbiotic reduced significantly both the duration of diarrhea [Weighted mean difference (WMD) = -1.05 day, 95% CI (-1.98, -0.11)] and the hospital stay duration [Standard mean difference (SMD) = -2.87 days, 95% CI (-5.33, -0.42)], especially in specific patient subsets. In both groups, similar rates of vomiting and nutritional recovery were observed. No probiotics or synbiotics-related adverse effects were reported. Subgroup analyses showed that probiotic and synbiotic treatment were more effective in reducing risk of diarrhea in outpatients [Risk ratio (RR) = 0.86, 95%CI (0.75-0.98)]. CONCLUSION: This meta-analysis supports the potential beneficial roles of probiotics and synbiotics on diarrhea in undernourished children.

Severe acute malnutrition in children admitted in an Intensive Therapeutic and Feeding Centre of South Kivu, Eastern Democratic Republic of Congo: Why do our patients die?

BACKGROUND: Severe acute malnutrition (SAM) remains a serious public health concern in low- and middle-income countries. Little is known about treatment outcomes of child inpatients in Intensive Therapeutic and Feeding Units. This study aimed to assess treatment outcomes of SAM and identify factors associated with mortality among children treated at Saint Joseph Nutritional Center, South Kivu, Eastern Democratic Republic of Congo. METHODS: A retrospective hospital-based cross-sectional study was conducted on medical records of 633 severely malnourished children followed as inpatients at Saint Joseph Nutritional Center from July 2017 to December 2018. Data were entered, thoroughly cleaned and analyzed in SPSS version 25. Univariable and multivariable logistic regression model were fitted to identify factors associated with mortality. RESULTS: Among 633 patients admitted with SAM, 13.1% were lost to follow-up and 9.2% died while in hospital. Children with late referral to the health facility (> 14 days) after the onset of main external malnutrition signs had 2.03 times higher odds of death than those referred less than 14 days [AOR = 2.03 at 95%CI (1.12, 3.68)]. The odds of death was 1.91 times higher for children with MUAC < 115 mm than for those with MUAC ≥ 115 mm [AOR = 1.91 at 95% CI (1.05, 3.50)]. Children infected with HIV were 3.90 times more likely to die compared to their counterparts [AOR = 3.90 at 95% CI (2.80, 9.41)]. CONCLUSION: Particular emphasis should be placed on partnering with communities to improve information on malnutrition signs and on critical importance of early referral to the health system. While HIV incidence in DRC is still low (0.21%), its impact on mortality among severely malnourished children is increased due to the limited access to HIV testing and antiretroviral therapy.

Human respiratory syncytial virus: prevalence, viral co-infections and risk factors for lower respiratory tract infections in children under 5 years of age at a general hospital in the Democratic Republic of Congo.

PURPOSE: This study aimed to determine the prevalence of human respiratory syncytial virus (HRSV) acute respiratory infection (ARI) in children under the age of 5 years at the Provincial General Hospital of Bukavu (PGHB), and to analyse factors associated with the risk of ARI being diagnosed as lower respiratory tract infection (LRTI). METHODOLOGY: A total of 146 children under 5 years visiting the PGHB for ARI between August and December 2016 were recruited, and socio-demographic information, clinical data and nasopharyngeal swabs were collected. The samples were analysed by a multiplex reverse transcriptase polymerase chain reaction targeting 15 different viruses. RESULTS: Of 146 samples collected, 84 (57.5 %) displayed a positive result of at least one of the 15 viruses. The overall prevalence of HRSV was 21.2 %. HRSV A (30, 20.5 %) was the virus the most detected, followed by HRV (24, 16.4 %), PIV3 (20, 16.6) and ADV (7, 4.79 %). The other viruses were detected in three or fewer cases. There were only 11 (7.5 %) cases of co-infection. HRSV infection, malnutrition, younger age, rural settings, low income and mother illiteracy were associated with the risk of ARI being diagnosed as LRTI in bivariate analyses but, after adjusting for the confounding factors, only HRSV infection and younger age were independently associated with LRTI. CONCLUSION: The prevalence of HRSV is high among children visiting the PGHB for ARI. HRSV infection and lower age are independently associated with the risk of ARI being diagnosed as LRTI.

Delayed initiation of breastfeeding in Bukavu, South Kivu, eastern Democratic Republic of the Congo: a cross-sectional study.

BACKGROUND: Timely initiation of breastfeeding can decrease neonatal mortality. However, about 50% of newborns are not breastfeed within 1 h of birth in the Democratic Republic of Congo. The aim of this study was to identify factors associated with delayed initiation of breastfeeding in an urban and rural area of Bukavu, South Kivu province, Democratic Republic of Congo. METHODS: We interviewed 396 mother-newborn pairs (185 in the urban area and 211 in the rural area) between 20 July and 10 October 2016. We used descriptive statistics to demonstrate the prevalence of early initiation of breastfeeding. Variables that showed association with delayed initiation of breastfeeding in the bivariate models were entered in a multivariable logistic model. RESULTS: Overall, the rate of early initiation of breastfeeding was 65.9% (69.7% in the rural area, 61.6% in the rural area). Two hundred and seventy-four (62.9%) mothers (159 in rural area and 115 in urban area) were counselled on early initiation of breastfeeding during prenatal care. Most mothers, 65.2% received counselling by a health professional. On multivariable regression analyses after adjusting for other variables in the model, unmarried mothers [Odds Ratio (OR): 1.5 (95% Confidence Interval (CI): 1.13, 1.95)], cesarean delivery [OR: 2.24 (95% CI: 1.74, 2.88)], no counselling on timely initiation of breastfeeding [OR: 1.71 (95% CI: 1.29, 2.20)] and counselling by a non-health professional [OR: 1.84 (95% CI: 1.08, 3.12)] were associated with delayed initiation of breastfeeding. CONCLUSION: Systemic changes are needed for women having caesarean births to experience skin-to-skin and early initiation. In addition, information, education and communication on the importance of timely initiation of breastfeeding must be supported to improve maternal and infant wellbeing.

Facteurs de risque associés à la mortalité néonatale dans un hôpital de niveau de soins tertiaires de Bukavu/ Sud-Kivu 'RDC'

En République Démocratique du Congo, le taux de mortalité néonatale le plus élevé(47‰) se trouve au Sud-Kivu. L'objectif de notre étude est d'analyser les facteurs de risque de mortalité néonatale dans une structure tertiaire de santé de cette province.Il s'agit d'une étude transversale couvrant la période de 2009-2013. Tous les enfants âgés de 0 à 28 jours étaient inclus dans l'étude.Les tests statistiques utilisés étaient le pourcentage, le Khi2 et l'odd ratio.Au total, 1638 nouveau-nés étaient admis dans le service. Le taux de mortalité néonatale était de 26.6%(passant de 40.8%en 2009 à 21.2% en 2013). La mortalité épurée était de 16.7%. Les facteurs de risque liés à la mortalité néonatale étaient (OR, p) :le sexe masculin [1.4 (1.1-1.9); p=0.0138], la prématurité [4.3 (2.9-6.4); p<0.0001],l'asphyxie périnatale [2.6 (2.1-3.2);p<0.0001], l'âge de la mère > 35 ans [1.2(1.2-3.2); p=0.0061], les mères célibataires[2.8 (1.4-5.8); p=0.0034], une menace d'accouchement prématuré [3.0 (1.3-7.1); p=0.0111] et la naissance dans une maternité autre que celle de l'HPGRB [5.3(4.0-7.1); p<0.0001].Le taux de mortalité néonatale reste élevé bien que des efforts aient été fournis pour sa réduction. Différents facteurs de risques associés à la mortalité néonatale ont été identifiés. Des actions desensibilisation/prévention doivent être soutenues pour réduire ce fléau

[Infectious profile and mortality of children aged 0-5 years admitted with severe acute malnutrition: a retrospective cohort study conducted in the Therapeutic Nutritional Center in Bukavu, Republic of Congo]. / Profil infectieux et mortalité des enfants âgés de 0 à 5 ans admis pour malnutrition aiguë sévère: étude de cohorte rétrospective au Centre Nutritionnel et Thérapeutique de Bukavu, République Démocratique du Congo.

INTRODUCTION: Malnutrition is a backdrop on which several infections are grafted. The aim of this study is to determine the most lethal infections, the median length of stay and the median daily weight gain of malnourished children. METHOD: A retrospective cohort study of malnutrition in children aged 0-59 months hospitalized in the Therapeutic Nutritional Center in Bukavu from 1 January 2011 to 31 December 2013. The evaluation of the risk of deaths related to infectious complication was made measuring the relative risk. Mann-Whitney test was used for comparing the medians. Adjusted odd ratios using logistic regression and 95% confidence interval for the risk of mortality were given for each infectious cause. RESULTS: A total of 574 children were included in the study. Five hundred twenty-one (90.8%) children were cured, 10 (1.7%) had discontinued treatment and 43 (7.5%) had died. The median length of stay was 19 (13-26) days and the median daily weight gain was 7 (3-13) g/kg/j. There was a statistically significant association between mortality and sepsis/septic shock (p = 0.0004), meningitis (p = 0.00001) and HIV infection (p = 0.02). CONCLUSION: A better management of acute malnutrition in our region should be based on the establishment of specialized and well equipped units for the treatment of malnutrition associated with severe infections.
