Paediatric dilated cardiomyopathy in Khartoum state, Sudan: a prospective study.

BACKGROUND

Dilated cardiomyopathy (DCM) is a disease of the heart muscle that affects ventricular function; it is a debilitating disease that can lead to heart failure and death in children. There is a lack of good epidemiological data about paediatric DCM in Sudan or in sub-Saharan Africa.

OBJECTIVE

To study the incidence, causes and outcome of DCM among children in Sudan.

METHODS

A prospective cross-sectional study that was conducted in three paediatric hospitals in Khartoum state, Sudan over the period of 6 months.

RESULTS

During the study period, 55 children were seen with the diagnosis of DCM; The female: male ratio was 1.9:1. The incidence of DCM in Khartoum state was found to be 1.4 cases per 100 000 children per year, 10 children (18 %) were diagnosed in the first year of their life. Twenty-seven children (49 %) showed evidence of failure to thrive, being below the fifth percentile for weight. The most common cause of DCM was found to be postviral in 27 children (49%), followed by Idiopathic in 25 children (45%). The most common presentation was the shortness of breath in 53 children (97%), on echocardiography 26 children (47 %) showed evidence of severe left ventricular impairment and 23 children (42%) showed moderate ventricular impairment. Regarding the outcome, 8 children (15%) recovered, the condition of 11 children (20%) remained static and there were 36 deaths (65%).

CONCLUSION

The incidence of DCM in Sudanese children was found to high with a higher mortality compared with middle-income and high-income countries; Improvement in the entire health system is needed to tackle this condition.
