Abstract
Objectives and study design: Zambia is a high tuberculosis burden country. Antituberculous medicines are the mainstay of tuberculosis management. There have been several reports of antituberculous drug-related haematological and hepatic adverse effects noted in other settings. Adverse events have healthcare cost and morbidity implications. Prevalence and severity of these adverse effects is understudied in patients at University Teaching Hospitals hence the purpose of this study was to identify haematological and hepatic abnormalities and compare parameters before treatment and after completion of intensive phase among the patients. Factors associated with abnormalities were also determined. A prospective longitudinal study was undertaken at Chest Clinic between April 2018 and July 2018. Study patients were followed up for 2 months. Full blood count and liver function tests were recorded at base-line and at follow-up. Abnormalities were defined according to 2017 Department of AIDS Table for Grading the Severity of Adult and Paediatric Adverse Events. Data were analysed using SPSS version 22.0 Paired t-test and Wilcoxon matched - pairs signed rank test were used to compare parameters. Logistic regression was performed to determine factors that were predictive of abnormalities. A p< 0.05 was considered statistically significant. Results: A total of 37 patients were involved in the study. 56.8% of patients were male. Mean age of patients was 36.2 years (19 – 57 years) while body mass index was 21.9 kg/m2. Only 37.8% of patients were sputum smear positive at baseline. 56.8% of patients had HIV co-infection. 45.9% of patients were on antiretroviral therapy.45.2% of patients had grade 1-3 aspartate transaminase derangements at follow-up compared to 29.7% at baseline. 5.4% of the patients had grade 1-3 alanine transaminase derangements at baseline while 9.7% of patients had grade 1 at follow-up. Fewer patients (16.1%) had grade 1-2 anaemia at follow-up while 62.2% of patients at baseline had grade 1-4 anaemia. More patients (46.2%) had platelet derangements at follow-up compared to 25.8% at baseline. Fewer patients had differential white cell count derangements at follow-up compared to baseline. Statistically significant differences in haematological parameters: haemoglobin concentration, haematocrit, red, and white cell, eosinophil and neutrophil counts at baseline and follow-up were found. However, no statistical significant differences in red cell indices were observed. Changes in alanine transaminase levels at baseline and follow-up were statistically significant. Logistic regression was performed to determine the effects of age, gender, body mass index, HIV infection, antiretroviral therapy, sputum smear status, and appropriate baseline full blood count/liver function test parameters on the likelihood of study patients having deranged haemoglobin concentration, white cell count and alanine transaminase at follow-up. Logistic regression models to predict deranged haemoglobin concentration and white cell count were statistically insignificant. None of the predictor variables were associated with likelihood of derangements in alanine transaminase. Conclusion: Findings of this study show that haematological and hepatic adverse effects were relatively fewer at follow-up and were mostly grades 1-3 in severity. Antituberculous therapy is relatively safe for patients during the initial phase.References
