Baricitinib

Under Review

This monograph is pending review by the Periscope clinical trial team from University of York

Issues for surgery 

Risk of perioperative flare in disease activity (potentially leading to an increase in glucocorticoid use), if omitted. 

Risk of post-operative infection if continued. 

Risk of venous thromboembolism (VTE), particularly if continued - see Further information

Advice in the perioperative period 

Elective surgery  

Establish indication and dose (see Further information). 

The Surgical Team and patient’s Rheumatologist / Dermatologist along with the patient should be involved in the planning for elective surgery to balance the potential benefit of preventing post-operative infection by stopping baricitinib against the risk of developing severe or unstable disease. 

Modifiable risk factors for perioperative infection, such as glycaemic control and smoking should ideally be addressed prior to surgery.  

Glucocorticoid use is associated with increased perioperative infection in a dose dependent manner. Where possible consider delaying elective surgery until patients taking baricitinib can be managed on less than 15mg prednisolone (or equivalent).  

Minor procedures 

Consider continuing baricitinib before low-risk surgery (i.e. surgery without a break in sterile technique, during which the respiratory, gastrointestinal, and genitourinary tracts are not entered) e.g. endoscopy, bronchoscopy, hysteroscopy, cystoscopy, breast biopsy, dermatologic or ophthalmological procedures. 

Ensure adequate thromboprophylaxis if continued (see Further information). 

All other procedures 

Surgery should be scheduled to enable the patient to miss THREE days of baricitinib (i.e., scheduling surgery for 4 days after last dose of baricitinib).  

EXCEPT:

If the Surgical Team deem the procedure to be of especially high infection risk, consider stopping 7 days before surgery. However, a flare in disease activity may occur, which may result in glucocorticoids being administered, further increasing the infection risk. 

Patients with coronavirus (COVID-19) 

If elective surgery is scheduled in a patient recently treated with baricitinib for COVID-19 shared decision making should consider the risks of proceeding with surgery, in relation to baricitinib use and the potential for increased complications due to recent COVID-19 infection. 

Emergency surgery  

Consider withholding any doses due in the immediate post-operative period to reduce risk of VTE and infection. Monitor closely for infection and post-operative VTE.  

Ensure adequate thromboprophylaxis (see Further information). 

Patients presenting with new onset abdominal signs and symptoms 

Patients presenting with new onset abdominal signs and symptoms should be evaluated promptly for early identification of diverticulitis or gastrointestinal perforation. If diagnosed stop baricitinib and discuss with Specialist – see Further information

Patients with coronavirus (COVID-19) 

If urgent surgery is required in a patient being treated with baricitinib for COVID-19 shared decision making should consider the risks of proceeding with surgery, in relation to baricitinib use and the potential for increased complications due to concomitant COVID-19 infection. 

Perioperative considerations 

Control of body temperature and avoidance of blood transfusion may minimise the risk of infection1.   

Post-operative advice 

Recommence post-operatively once wound healing stable – discuss with Surgical Team. To prevent relapse consideration should be given to restarting baricitinib 3 - 5 days after surgery if no concerns. Ideally treatment interruption should not exceed 14 days (see Further information). 

If post-operative bloods indicate haemoglobin, neutrophils or lymphocytes below normal range or liver function tests elevated, consult product literature as treatment interruption may be required – discuss with Specialist. 

If post-operative VTE, or infection, develops discontinue baricitinib and discuss with Specialist. 

Interactions with common anaesthetic agents 

None. 

Interactions with other common medicines used in the perioperative period 

None.

Indications, dosing frequency and half-life 

Baricitinib is used for rheumatoid arthritis, atopic eczema, and alopecia areata. This is an oral formulation, and doses are administered once daily.  

Venous thromboembolism (VTE) risk 

Ensure patients receive adequate thromboprophylaxis when undergoing surgery as serious VTE events have been observed in patients taking baricitinib. In a randomised post authorisation safety study in patients with rheumatoid arthritis who were 50 years of age or older with at least one additional cardiovascular risk factor, a dose-dependent increased risk for VTE was observed with tofacitinib compared to tumour necrosis factor (TNF) inhibitors. Following a European safety review this increased risk of VTE is regarded as a JAK inhibitor class effect. It is not known if pre-operative cessation of baricitinib reduces the VTE risk back to baseline. 

MHRA / CHM advice: Baricitinib (Olumiant): increased risk of diverticulitis, particularly in patients with risk factors (August 2020)

A European review of worldwide data concluded baricitinib is associated with an increased risk of diverticulitis. The MHRA recommend baricitinib is used with caution in patients with pre-existing diverticular disease, or who are taking non-steroidal anti-inflammatory drugs, corticosteroids, or opioids due to the risk for gastrointestinal perforation. Patients should be advised to seek immediate medical attention if they experience severe abdominal pain especially accompanied with fever, nausea or vomiting, or other symptoms of diverticulitis.  

Rationale for recommendations - risk of infection versus risk of disease  

Inflammatory arthritis  

Baricitinib is known to increase the risk of serious infections, particularly in the elderly, hence use is not recommended in patients over 65 years old unless there is no suitable alternative. Baricitinib has a short half-life; approximately 12 hours. However, concerns that the duration of pharmacodynamic activity of JAK inhibitors is longer than the half-life initially led to the American College of Rheumatology / American Association of Hip and Knee Surgeons (ACR / AAHKS) recommending to stop 7 days pre-operatively, however, they have since revised their guidance and recommend stopping 3 days prior to arthroplasty (with the caveat that a longer cessation period may be considered if history of infections or previous prosthetic joint infection). This aligns with the recommendations from the German Society for Rheumatology. The change in advice is attributed to a sub-study which showed a rapid increase in disease activity after discontinuing tofacitinib with patients experiencing flares within 2 weeks, sooner than with TNF inhibitors.  These findings are expected to extrapolate to baricitinib. 

Eczema 

Whilst there are currently no recommendations from dermatology societies regarding the perioperative management of JAK inhibitors it seems reasonable to extrapolate the recommendations from rheumatology societies.
