The goal of this clinical trial is to assess the efficacy of tofacitinib in refractory axial spodyloarthritis (ax-SpA) with dose escalation from 10mg to 15mg. Patients will start on 10mg and then divided into 2 groups (10 and 15) at 3rd month according to major improvement criteria. The main question\[s\] it aims to answer are: * Efficacy and safety of tofacitinib in different doses * If escalation of tofacitinib is justified if clinical criteria is not fulfilled at 10mg
Axial Spondyloarthritis
Tofacitinib
PHASE4
Axial spondyloarthritis (ax-SpA) is a major cause of chronic low back pain in the young. It causes significant disability and impairs quality of life. Management of (ax-SpA) includes physical therapy along with NSAIDs, followed by TNFi or IL-17i or JAKi in refractory ax-SpA. In Bangladesh, TNFi and IL-17i are expensive, whereas Tofacitinib (JAKi) is affordable and widely used in Bangladesh. However, recent study shows that a significant number of patients, 39.4% do not meet criteria for ASDAS CRP clinically important criteria and only 26% meets the criteria for ASDAS major improvement to tofacitinib 10mg daily. 102 patients of refractory ax-SpA meeting the enrollment criteria will be taken and put on 10mg tofacitinib. Those who fail to attain ASDAS CRP major improvement criteria at 12 weeks will be put on 15mg tofacitinib and both the groups will be compared at week 24 in a dose escalation study. No studies have been done on 15mg tofacitinib for ax-SpA, such a study will provide us ground for escalation of tofacitinib. Regarding safety issues, FDA has warned against the use of 20mg tofacitinib but not for 15mg. Baseline characteristics and variables will be recorded at initiation of therapy, 4th, 12th and 24th week. The study will take place in Rheumatology outdoor, BSMMU and Modern One Stop Arthritis Care and Research Centre, Dhaka from July 2022- April 2024. Patient's socio-demographic and clinical data will be taken in a semi-structured questionnaire. At every follow up detailed history, thorough physical examination and investigations will be done to evaluate the efficacy and adverse effects. Patients will be assessed for response, ASDAS-CRP, ASDAS-ESR, ASAS-20, BASFI, BASDAI, BASMI, ASQoL, SF-36, MASES and VAS will be noted. CBC, CRP, S. creatinine and S. ALT will be done during follow up.
