Choosing and using non-steroidal anti-inflammatory drugs in haemophilia

The management of pain and inflammation in haemophilic arthropathy is challenging due to the lack of anti-inflammatory analgesic agents perfectly suitable for this population. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in the management of arthritis due to their analgesic and anti-inflammatory effects. Their use in persons with haemophilia (PWH), however, is limited due to increased risk of bleeding mainly from the upper gastrointestinal (UGI) tract. Cyclooxygenase-2 (COX-2) selective NSAIDs which have comparable analgesic effect to traditional NSAIDs (tNSAIDs) but with less UGI bleeding have been considered to be a suitable option for treatment of haemophilic arthropathy. COX-2 inhibitors, however, have an increased in the risk of cardiovascular (CV) disease. Although the atherosclerotic burden in PWH is similar to that in the general population, the risk of CV-related deaths is lower. PWH have a higher risk of GI bleeding and lower risk of thrombotic disease compared to general population. Therefore, when PWH require anti-inflammatory/analgesic agents, it seems reasonable to use lowest dose of COX-2 inhibitors for the shortest period together with a proton pump inhibitor. Helicobacter pylori infection should be tested for and eradicated prior to starting NSAID treatment in PWH. Furthermore, regular blood pressure and renal function test monitoring is required during COX-2 inhibitor treatment.
