Acute Renal Failure in Children at the University Hospital of Brazzaville ()
1. Introduction
Acute renal failure (ARF), a rapid deterioration of renal function resulting in elevated plasma creatinine and inability of the kidney to eliminate waste nitrogen metabolism and maintain the body’s electrolytic balance [1] , is a medical emergency. It is reversible in most cases, but may be life-threatening [1] [2] . It is one of the leading causes of morbidity and mortality in children [3] [4] . Its pediatric prevalence is 0.8 per 100,000 habitants in the United Kingdom [5] , 0.39% in the United States [6] , 4.5% in Canada [7] , with mortality rates of 25%, 15.3%, 3.5%. In Africa, some hospital surveys are reported by Aloni in the Democratic Republic of Congo (DRC): 1.78% [8] , Keita in Senegal: 0.91% [9] , Ifeoma in Nigeria: 1.0% [10] and Coulibaly in Burkina Faso: 3.3% [11] with respectively 25%, 34%, 40.5%, 10.1% of deaths. The diagnosis of ARF is made by biological examinations and its management depends on the causes.
In Congo, according to Assounga [12] , the pediatric frequency of the ARF at the University Hospital of Brazzaville in 2000 was 0.99% with 37% of deaths. Recently, seventeen years later, our study was carried out in the same hospital, and intended to contribute to improving the management of inpatient children with ARF and aimed to: determine epidemiological aspects of pediatric ARF, identify causes, describe the evolutionary profile and identify factors associated with mortality.
2. Methodology
It was a cross-sectional, retrospective study conducted from January 2016 to December 2018 at the University Hospital of Brazzaville, a Level III health facility. It has 22 clinical departments, including three pediatric departments (infant, older children and intensive care), which are part of the study.
Children aged from one month to 17 years, hospitalized in one of the pediatric departments, and whose discharge diagnosis included among others the item ARF were included.
Newborns and children hospitalized for chronic renal failure were not included. Inaccurate records, duplicates, and children with uncomplicated renal disease were excluded.
This sample was exhaustive. The data was collected on a pre-established survey form.
The variables studied were: socio-demographic: age, sex, place of residence and provenance of the child; the age, occupation, education and socio-economic status of the parents; Clinical: period and motive of hospitalization, symptoms presented before admission and at admission: diuresis, presence of edema, temperature, respiratory distress, state of consciousness, state of hydration and nutritional, paleness, blood pressure. Para-clinical variables: serum creatinine, blood urea, hemogram, blood ionogram, serum calcium, phosphoremia, bicarbonate, blood gas, haptoglobin, blood smear, C3 complement, coombs test, urine test strip, 24-hour proteinuria, urine cytobacteriological examination (UCBE), electrocardiogram, renal and/or abdominal ultrasound, chest X-ray, abdominal radiography without preparation, percutaneous renal biopsy (PRB).
Other variables: stage of ARF, type of ARF, etiology of ARF, treatment, evolution.
2.1. Operational Definitions
ARF was defined as a rapid and usually reversible decrease in the glomerular filtration rate leading to uremia and fluid and electrolyte disturbances. It is characterized by a recent elevation (<3 months) of serum creatinine, which may display preserved diuresis (>500 ml/24h) or oliguria (100 - 500 ml/24h) or anuria (<100ml/24h) [13] .
The staging of the ARF used was that of the modified RIFLE (Table 1) classification for pediatrics (pRIFLE) [14] . The estimated clearance of creatinine is calculated according to Schwartz’s pediatric formula [15] and compared to a reference value of 100 ml/min/1.73m2 in the absence of a known prior value.
Acute renal failure is called functional or pre-renal, when there is a decrease in glomerular perfusion; organic or intrinsic, a dysfunction of different renal structures (tubules, glomeruli, interstitium or vessels) and obstructive or post-renal, when there is an obstacle on the urinary tract [16] .
Complete recovery of renal function: was defined by the normalization of serum creatinine and blood urea output.
Partial recovery of renal function: was defined as resumption of diuresis with improvement of renal function without normalization of serum creatinine and/or blood urea. Chronicity: was defined by the lack of normalization of renal function beyond three months.
2.2. Statistical Analysis
The data were entered and processed using SPSS version 20.0 and Microsoft Excel 2010. The qualitative and quantitative variables were expressed in percentages ± standard deviation, respectively. The comparison of the means between variables was performed by Pearson’s chi-square for qualitative variables, the Student’s test for quantitative variables. The Odd Ratio (OR) calculation and their confidence interval (CI) were required. The threshold of significance was set at 0.05.

5. Discussion
The purpose of this study was to improve the management of children with ARF hospitalized at the Brazzaville University Hospital, and to describe epidemiological aspects, identify the causes, describe the evolutionary profile and identify the factors associated with death. This study, although hospital and mono-centric, has the advantage of being carried out in the only Pediatric Intensive Care Unit in Brazzaville. But, it presents some pitfalls; the most important is the retrospective nature of the study source of bias, lost sight of but also in the collection of

data. Thus, the results of this study can be extrapolated to the entire child population of Brazzaville. It worth to be done specially since there is only pediatric intensive care unit in Brazzaville. But, there are some pitfalls, the first of which is related to the mono-centric character and the second due to the retrospective nature of this study, sources of bias in lost-to-follow-up.
The prevalence of pediatric ARF varies from one country to the other depending

on methodological differences and the level of health facility. The available data are essentially those of multicenter surveys. Its prevalence is 1.3% in this study as in that of Assounga [12] in the same hospital. Similar prevalence is reported by Keita in Senegal and Ifeoma in Nigeria [9] [10] respectively 0.91% and 1.0%. Higher prevalence is noted in the work done in the DRC, Algeria, Nigeria, Burkina Faso and Brazil [8] [11] [17] [18] [19] with respective rates of 1.78%, 3.07%, 3.13%, 3.3%, and 8%. In contrast, those in China and the United States report low prevalence of 0.32% and 0.39 [6] [20] . These disparities can be explained, among other things, by the delay in consultation and, in particular, the management of ARF etiologies in developing countries.
The age of onset varies from one study to another and is a function of the target population. It is on average 71.5 ± 67 months in our study as described in the works of Gheissari, Ifeoma, Batouche and Bunchman [10] [18] [21] [22] . In Senegal, Burkina Faso, Pakistan and the United States the average age varies between 80.4 and 129.6 months [6] [9] [11] [23] . Younger children from 12.79 to 67.2 months are the most reported in the works of Riyuzoa, Abdullah, Oubella, Moghtaderi, Shalaby, Moussa Ntondi, Cao and Damte Shimelis [24] - [30] .
The male predominance noted in the literature [8] [11] [22] [25] [31] is found in this study without any significant difference.
The reasons for consultation and the revealing symptoms are also variable from one study to another, depending on the etiology and the existence of complications relating to delay in consultation [29] . The predominant symptoms are: respiratory distress, hypodynamic, convulsions, fever, oligoanuria [11] [29] [32] - [37] . The definitive diagnosis is provided by creatinine, which has been significantly contributive to this study.
Diagnosis is made at the stage of renal failure (58.1%) as in Halle works 86.2% [38] , Oubella 81% [26] , Jakanattane 35.9% [35] , Duzova 43.0% [34] , Tresa 76.7% [23] , Riyuzo 94.8% [24] and Batouche [18] . In China and Saudi Arabia, the risk stage predominates [20] [28] .
In terms of etiologies, the predominance of severe dehydration in the occurrence of functional ARF of the child is a known fact [9] [12] [23] [40] . It was hypovolemic in 83% of cases in this study. Other causes are: severe malaria, the first cause of functional ARF in black Africa [1] [11] [29] , second cause in our study and severe sepsis, whose genesis in the occurrence of functional ARF is well known [21] [25] [26] [28] [33] [35] [38] [39] [40] .
The evolution of ARF in children is generally favorable [9] [12] [26] [33] [35] [36] [41] [42] . But it can be laced with complications including hyperkalemia, acute pulmonary edema and metabolic acidosis [35] [37] . Its prognosis is depending to the etiology, the speed of management and the level of the health facility and the accessibility to extra-renal purification. The lethality of 34.4%, found in this study is similar to that of Assounga [12] . Lethality varying between 32% and 56.2% are reported in Côte d’Ivoire, Nigeria, Senegal, Saudi Arabia, Morocco, Turkey, Baghdad, Brazil, Nigeria, Thailand, India, in Kuwait, Togo, Cameroon and Lithuania [9] [17] [27] [26] [34] [25] [19] [10] [33] [35] [36] [38] [40] [41] [42] [43] . Lesser lethality is reported in developed and developing countries with extra-renal purification centers [11] [18] [20] [21] [23] [29] [31] [39] [42] [44] [45] [46] .
The risk factors for death reported in Morocco, Bangladesh, India, Lithuania and Iran [26] [31] [36] [39] [46] are age below five years, provenance of the child, the existence of deep coma, severe dehydration, undernutrition, oligoanuria, ARF at failure stage, lack of dialysis and hospital stay of less than seven days.
Conclusion
The ARF of the child is frequent at the University Hospital of Brazzaville. It predominates in children under 36 months and low socioeconomic status. Severe dehydration is the main etiology. High lethality reflects its severity. Young age, provenance of the child, severe dehydration, deep coma, oligoanuria, stage of renal failure and absence of an extra-renal purification center are some of the factors associated with death of inpatient children with ARF.
