Abhishek, A., Grainge, M. J., Card, T., Williams, H. C., Taal, M. W., Aithal, G. P., Fox, C. P., Mallen, C. D., Stevenson, M. D., Nakafero, G., & Riley, R. D. Risk-stratified monitoring for sulfasalazine toxicity: prognostic model development and validation

Background Sulfasalazine induced cytopenia, nephrotoxicity, and hepatotoxicity is uncommon during long-term treatment. Some guidelines recommend three monthly monitoring blood-tests indefinitely while others recommend stopping monitoring after one ye...

British Journal of Dermatology, 190(4), 559-564. https://doi.org/10.1093/bjd/ljad430

Background: There is no evidence base to support the use of 6-monthly monitoring blood tests for the early detection of liver, blood and renal toxicity during established anti-tumour necrosis factor alpha (TNFα) treatment. Objectives: To evaluate the...

Background: Patients established on thiopurines (e.g., azathioprine) are recommended to undergo three-monthly blood tests for the early detection of blood, liver, or kidney toxicity. These side-effects are uncommon during long-term treatment. We deve...

BMJ, 381, Article e074678. https://doi.org/10.1136/bmj-2022-074678

OBJECTIVE: To develop and validate a prognostic model to inform risk stratified decisions on frequency of monitoring blood tests during long term methotrexate treatment. DESIGN: Retrospective cohort study. SETTING: Electronic health records within th...
