ANKYLOSING SPONDYLITIS
INVESTIGATION & TREATMENT MODALITIES
![Page 2: Ankylosing spondylitis management](https://reader035.fdocuments.in/reader035/viewer/2022081422/55505112b4c905b2788b53c5/html5/thumbnails/2.jpg)
EVERY PATIENT SHOULD BE CAREFULLY EVALUATED AND INDIVIDUALIZED ,IN ORDER TO PROVIDE HIM THE BEST TREATMENT FOR A BETTER OUTCOME.

THE PATIENT SHOULD BE EXPLAINED IN DETAIL ABOUT HIS CONDITION AND THE POSSIBLE OUTCOME AND COMPLICATIONS, AND THAT THE TREATMENT IS ONLY DIRECTED TOWARDS IMPROVING THE QUALITY OF LIFE.

MANAGING A CASE OF ANKYLOSING SPONDYLITIS IS A TEAMWORK COMPRISING OF :
ORTHOPAEDISTS RHEUMATOLOGISTS PHYSICIANS PHYSIOTHERAPISTS PARENTS

RECOGNITION OF A FULL BLOWN CASE IS NOT DIFFICULT

DIAGNOSIS
![Page 6: Ankylosing spondylitis management](https://reader035.fdocuments.in/reader035/viewer/2022081422/55505112b4c905b2788b53c5/html5/thumbnails/6.jpg)
THE NEED, IS OF A EARLY DIAGNOSIS OF THE DISEASE ,WHICH WOULD HELP IN A BETTER PROGNOSIS AND THIS HAS BEEN MET BY THE TWO GROUPS NAMELY:
THE ROME CRITERIA (1963)
THE NEW YORK CRITERIA (1968)

DIAGNOSIS
![Page 7: Ankylosing spondylitis management](https://reader035.fdocuments.in/reader035/viewer/2022081422/55505112b4c905b2788b53c5/html5/thumbnails/7.jpg)
ACCORDING TO THIS ,AS IS DIAGNOSED IF B/L SACROILIITIS IS SEEN ALONG WITH ONE OF THE FOLLOWING.
a) LBA & STIFFNESS OF 3 MONTHS DURATION NOT RELIEVED BY REST
b) PAIN AND STIFFNESS IN THE THORACIC SPINE
c) LIMITED LUMBAR SPINAL MOVEMENTd) LIMITED CHEST EXPANSIONe) HISTORY OR EVIDENCE OF IRITIS OR ITS
SEQUELAE

THE ROME CRITERIA
![Page 8: Ankylosing spondylitis management](https://reader035.fdocuments.in/reader035/viewer/2022081422/55505112b4c905b2788b53c5/html5/thumbnails/8.jpg)
CLINICAL CRITERIA:
a) LIMITATION OF LUMBOSACRAL MOVEMENT IN THREE PLANES
b) HISTORY OF PRESENCE OF PAIN AT DL JUNCTION WITH OR WITHOUT LUMBAR SPINE PAIN
c) LIMITED CHEST EXPANSION OF 2.5CM OR LESS AT 4TH INTERCOSTAL SPACE.

Bath Ankylosing Spondylitis Functional Index (BASFI)
Visual analog scale (VAS) – 10 cm Mean score of 10 questions Questions level of functional disability, including:
◦ Ability to bend at the waist and perform tasks◦ Looking over your shoulder without turning your body◦ Standing unsupported for 10 minutes without discomfort◦ Rising from a seated position without the use of an aid◦ Exercising and performing strenuous activity◦ Performing daily activities of living◦ Climbing 12 to 15 steps without aid

13
Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)
A self-administered instrument (using 10-cm horizontal visual analog scales) that comprises 6 questions:
Over the last one week, how would you describe the overall level of:◦ Fatigue/tiredness ◦ AS spinal (back, neck) or hip pain◦ Pain/swelling in joints other than above ◦ Level of discomfort from tender areas ◦ Morning stiffness from the time you awake◦ How long does morning stiffness last?

14
Modified New York Criteria for the Diagnosis of AS
Clinical Criteria◦ Low back pain, > 3
months, improved by exercise, not relieved by rest
◦ Limitation of lumbar spine motion, sagittal and frontal planes
◦ Limitation of chest expansion relative to normal values for age and sex
• Radiologic Criteria– Sacroiliitis grade 2
bilaterally or grade 3 – 4 unilaterally
• Grading– Definite AS if radiologic
criterion present plus at least one clinical criteria
– Probable AS if:• Three clinical criterion• Radiologic criterion
present, but no signs or symptoms satisfy clinical criteria

Appropriate Patients for Anti-TNF Therapy
Active disease for 4 weeks◦ BASDAI > 4 at two times, 1 month apart
Treatment Failures◦ All types AS – lack of response/intolerability > 2
NSAIDs for 3 months
◦ Patients with peripheral arthritis – lack of response/intolerability to > 1 DMARD, sulfasalazine preferred

31
Anti-TNF Agents Etanercept
◦ Dose: 50 mg SC per week as two 25 mg injections administered on same day or 3 to 4 days apart
Infliximab◦ Dose: 5 mg/kg IV at week 0, 2, and 6 and every 6
to 8 weeks thereafter

Etanercept Vs. Infliximab:Pharmacologic Characteristics
Etanercept Infliximab
Mechanism of TNF inhibition
“Decoy” receptor for TNF
Binds to TNF and inhibits it from binding with TNF receptor
Terminal half-life 4.25 +/- 1.25 days (mean+/- SD)
8 to 9.5 days (median values)
In vitro lysis of cells expressing transmembrane TNF
No Yes
Mode of administration Subcutaneous IV infusion (over 2 to 3 hours)

AS Treatment Algorithm:Patients with Axial AS
Alternative Options• Pamidronate• Thalidomide
*Only biologic approved for treatment of AS in US and Europe†Approved in Europe only for treatment of ASThis treatment algorithm contains unlabeled use of infliximab, pamidronate and thalidomide.
Anti-TNF agents• Etanercept 50 mg SC per week as two 25 mg injections in the
same day or 3-4 days apart*• Infliximab 5 mg/kg at 0, 2, and 6 weeks and every 6 to 8 weeks
thereafter†
• Contraindicated in patients with infections, tuberculosis, multiple sclerosis, lupus, malignancy, and pregnancy/lactation
Initiate physical therapy plan with long-term exercise program to accompanypharmacologic intervention• Emphasize posture, range of motion,
and strengthening
NSAIDs or Selective COX-2 inhibitors• Efficacy and safety comparable between non-selective agents• Selective COX-2 efficacy comparable, better safety profile, higher
cost that non-selective NSAIDs
Failure of at least two different NSAIDs/selective COX-2 inhibitorsfor minimum of 3 months

36
Monitoring and Discontinuing Treatment With Anti-TNF Agents ASAS core set of outcome parameters to
monitor patients◦ Physical function, pain, spinal mobility, patient’s
global assessment, stiffness, peripheral joints and entheses, acute phase reactant, fatigue
Assess at 6 to 8 weeks and discontinue patients who do not meet response criteria◦ BASDAI: Reduction of 2 units and◦ Physician Global Assessment > 1

AIM: TO MAINTAIN JOINT MOVEMENT AND TO BUILD UP MUSCLES THAT OPPOSE THE DIRECTION OF DEFORMITIES I.E EXTENSORS
IT SHOULD BE STARTED ALONG WITH THE DRUG THERAPY FOR BETTER OUTCOME OR AS SOON AS THE PT HAS RELIEF FROM PAIN.
