dc.description.abstractENGLISH SUMMARY: Purpose: Paediatric patients have more adverse drug reaction (ADR) rates than adults due to off-label use of medicines and the prevalence data of ADRs in Sub-Saharan African children is limited. The aim was to describe the prevalence and nature of ADRs in paediatric (≤ 16 years old) in-patients at a tertiary hospital in South Africa. Methods: We conducted a prospective study of paediatric in-patients to identify suspected ADRs. Children had to be admitted for at least 24 hours during the 3-month study period (1 December 2015 to 29 February 2016). The data collected included age, sex, diagnosis and medicines received. We assessed causality using the 10-question Naranjo probability scale and classified severity using the Hartwig severity scale. Results: We found that 18.4% (52/282) of patients had 61 ADRs. The median age of patients with ADRs was 1.4 years (interquartile range (IQR): 0.5 – 5.3 years). ADR was the reason for admission in a third of the patients (31%; 16/52). Paediatric oncology patients suffered the majority of the ADRs (56.5%; 13/23), followed by HIV-infected patients on antiretroviral therapy (ART) (42.9%; 9/21) and tuberculosis (TB) patients (17.5%; 7/40). HIV-TB coinfected patients also experienced a high 30.8% (4/13) rate of ADRs. The majority of the ADRs were moderate 45.9% (28/61), while 42.6% (26/61) were mild, and 11.5% severe ADRs (7/61). These ADRs range from severe neutropaenia 4.9% (3/61) and drug induced liver injury (DILI) 4.9% (3/61) to mild cutaneous rashes 13.1% (8/61). There were no fatal ADRs, while 13.1% (8/61) ADRs were considered life threatening; 27.9% (17/61) necessitated and/or prolonged hospitalisation and 31.1% (19/61) resulted in persistent or significant disability or incapacity. Thirty eight percent of ADRs (23/61) were predictable. Paediatric oncology patients on chemotherapy were 7 times more likely to have ADR(s) than other patient groups [OR 7.3 (3.0 – 17.9), p < 0.01]. More ADRs were associated with chemotherapy 44.3% (27/61) and antimicrobials 42.6% (26/61), while the other miscellaneous medicine classes were associated with 34.4% (21/61) of the recorded ADRs. Conclusion: The prevalence of ADRs was 18.4% and in 31% the ADR was the reason for admission. The ADRs in paediatric oncology patients were expected, but of note nearly half the HIV-infected patients (43%) suffered an ADR.en_ZA
