Jaundice is one of the reasons for frequent consultation in pediatrics. It is often reported by parents. At times, it is observed by the pediatrician due to the existence of another clinical symptom evoking a liver disease or hemolytic [1]. In practice, the pediatrician often comes across one of these following four situations: jaundice and stool discoloration, jaundice, haemolysis and isolated jaundice [2] [3]. Jaundices etiologies are many; we can divide them into two big categories according to the increase of serum bilirubin which can be non-conjugated bilirubin or conjugated bilirubin and of mixed cause as well [1].

In Mali, we don’t have statistics related to child and infant’s jaundice, which is the reason why we conducted this study of the infant and child’s jaundices etiologies in the paediatric ward at Gabriel Toure university hospital centre.

It was a prospective study led from 1^st January to 31^st December 2016 (12 months) in the paediatric ward of the university hospital centre of Gabriel Toure. The university hospital center of Gabriel Toure is a third reference hospital in the Bamako city, Mali’s capital, sahelo-saharan country. All infants and hospitalized children in the ward with icterus were included at the entry examination witin the study. The parameters studied within the searching were: anamnestic, clinical, paraclinical, treatment and scalable. The data were collected on a survey sheet, entered by Word and Excel software and then analyzed by SPSS version 20 software.

During the study we collected 168 files of infants and children with jaundice out of 8924 hospitalization or a frequency of 1.8%.

Jaundice in infants and children has been a little studied in Africa. As a result, few references have been found in Mali and Africa to discuss our findings.

The frequency of 1.8% was relatively high given the different etiologies likely to cause jaundice in children in our context of malaria-endemic countries.

The average age was 6 years and 3 months and the most common age group was 1 to 5 years with 39.5% (66 patients). Given that infectious etiologies were the most common, the high frequency (39.5%) of the 1 - 5 year age group could be explained by their vulnerability to infection. The average age of 6.3 of our series was close to that of the study carried Morocco in 2010 on the febrile icteres of the child who found an average age of 6.1 ± 3 year, with a median age of 5.5 years (extreme: 1 - 15 years) and children under the age of six were the most affected with 51.7% [4] [5]. The sex ratio was 1.6 in our study, this predominance of the male sex had been reported by several authors [2] [5].

Anemia and fever were the most common reasons for consultation with 26.7% and 23.8% respectively, and jaundice was the reason for consultation for 13% of patients. The association of icterus with fever is much found in infectious diseases such as malaria which the etiology the most common in our searching. Anemia can be explained by hemolysis, which is due to infectious pathologies, in this case malaria, and to certain constitutional pathologies such as drepanocytosis (sickle cell disease).

At the entrance clinical examination, 81% of the patients had a fever, 42.8% had digestive problems and 20.8% had abdominal pain. All of these signs are found in the infectious syndrome, which remains the most common etiological group in our study.

Feces were discoloured in 5.3% of patients and dark urine in 6.5%. The association of jaundice with coloured feces and dark urine evokes a cholestatic jaundice.

A hepatomegaly is most often a sign of hepatic suffering, its discovery most often leads to an infectious or cholestatic jaundice and requires an etiological assesment. It was found in 29% of our patients.

The predominance of infectious jaundice (75%) could be expalained by the poor hygienic conditions and especially by the fact that the study site is a malaria endemic zone.

The anemia found in 95% of patients could be explained by a high prevalence of martial deficiency in the pediatric population where the microcytosis (62%). According to Demographic and health survey-Mali V, 82% of children aged 6 to 59 months suffer from anemia [6].

The low rate of realisation of serum bilirubin (72/168) could be explained by the low income of the parents, free bilirubin was increased in 56/72 and conjugated bilirubin was increased in 21/72. Transaminases were carried out in 33/168 patients with high asparate aminotransferase in 27/33 and increased alamin aminotransferase in 24/33 explaining hepatic suffering due to hepatocyte damage. GGTs were increased in 14/18 patients and PALs were elevated in 10/15. This increase in GGTs points towards a cholestatic ictere.

The thick drop was the complementary examination aimed at the most requested diagnosis and was positive in 67% of patients, in our context every feverish patient is given a thick drop to confirm or rule out malaria. The etiologies were dominated by malaria (67%) followed by drepanocytosis (9%), hepatitis A (7%) and hepatitis B (4%). Other aetiologies such as biliary (tract) atresia, hepatic abscess and pneumonia were found but in very low proportions. In Morocco the etiologies are dominated by G6PD (glucose 6 phosphatase deshydrogenase) deficiency (18%), Wilson’s disease (18%) and hepatitis A (15%) [7]. Other studies carried out on the etiologiy of febrile jaundice had found hepatitis A as the first etiology with 91.5% [5] [8] [9] [10]. These results show a difference in the etiology of the jaundice between these two regions in Africa. In Mali, malaria is the first cause of death and death among children under 5 years, which represent 40% of the first cause of consultation in public health facility according to the health facility system data and its national prevalence is estimated to 52% [6].

Jaundice is a frequent sign in infants and children, the infectious etiologies are more frequent and dominated by malaria. Other etiologies such as sickle cell anemia and cholestatic jaundice (Bile duct atresia) should not be forgotten. The treatment is especially etiologic and the progress beneficial if the etiological support is premature and fitted.
