25
Can you initiate Urate lowering therapy during Acute Flare of gout?
Yes as it improves future adherence, but only if the pt is also being adequately treated for acute flare. It does NOT treat acute flare, if administered alone, can prolong flare duration. When initiating allopurinol, patients should continue taking anti-inflammatory flare prophylaxis for at least 3 to 6 months because urate lowering therapy Transiently raises the frequency of flare occurrence.
26
3 most Important considerations for using Colchicine in acute gout?
Most effective within first 24 hours of the episode. CKD GI toxicity causes dose limitations
27
Colchicine Dosage in acute gout
In absence of CKD, First dose- 1.2 mg One hour later- single 0.6 mg dose, then 0.6 mg daily
28
Treatment approach to acute gout- pharmacotherapy and non pharmacological
Drug options- Colchicine, NSAIDs, Predni based on pt comorbidities. Optional urate lowering therapy. Non-pharmacological - Topical ice.
29
Indications of kidney biopsy in SLE
Glomerular Hematuria Cellular Casts Spot UPCR > 500 Unexplained decrease in eGFR
30
First line therapy for Ank Spond
NSAIDs + Physical Therapy If an NSAID is started early in the course of AS (<3 yrs), 35% patients will enter remission compared to 12-15% of those starting it later. Unlike other rheumatologic diseases, NSAID has disease modifying effect in AS.
31
Second and 3rd line treatment for Ank Spond
2nd line- TNFi- Etanercept IL-17i - Secukinumab or Ixekizumab 3rd line (only if TNFi and IL-17i are contraindicated)- JKi (Janus Kinase inhibitors)- Tofacitinib and Upadacitinib
32
Drugs more useful in Peripheral Joint disease rather than axial
Nonbiologic agents like- MTx and Sulfasalazine
33
What cancer to monitor for in Sjogren?
Lymphoma, most commonly- Mucosa associated lymphoid tissue lymphomas
34
6 Risk factors for Lymphoma in Sjogren
Parotid gland enlargement Depressed C4 Elevated Rheumatoid Factor Elevated Anti-Ro/SSA and anti-La/SSB Monoclonal gammopathy Cryoglobulinemic Vasculitis
35
Primary vs Secondary Sjogren
Primary occurs in isolation Secondary occurs in setting of other rheumatologic diseases, most commonly- RA and SLE
36
Antibodies that can be seen in Drug Induced Lupus
Antihistone (Non specific) ANCA ( especially P-ANCA) and F-actin- seen with Minocycline ANA may be transiently positive but *typical autoantibodies of SLE are absent.
37
Drug induced lupus vs SLE (Idiopathic)
DLE is milder, characterized by more skin (acne) and Joint symptoms (could be similar other inflammatory arthritis like RA with symmetrical peripheral joint involvement) (No organ damage- urinalysis is normal. DLE may have transient ANA positive but lack typical autoantibodies to SLE
38
2 features that should trigger SLE in your head in a patient with arthralgia, regardless of gender?
TCP and abnormal urinalysis ( possible kidney disease)
39
First line treatment for mucocutaneous ulcerations in Behcet
Colchicine, followed by Apremilast
40

41
Autoinflammatory syndromes (FMF) pathophysiology
Monogenic disease, gene mutation causing activation of inflammasomes and expression of proinflammatory mediators like IL-1beta for FMF
42
5 clinical subtypes of Psoriatic Arthritis
Symmetric Polyarthritis asymmetric oligoarthritis distal interphalangeal predominant disease Spondyloarthritis Arthritis Mutilans
43
Criteria for diagnosis of Behcet Disease
International Criteria for Behcet Disease scoring system
44
Pathognomic feature of Behcet Disease
Pathergy
45
Clinical diagnostic features for FMF?
Multiple recurring episodes of fever, abdominal pain, rash and arthritis. Other symptom can be- serositis (including Pericarditis)
46
How to diagnose FMF
Clinical symptoms, definitively confirmed by genetic testing- MEFV gene mutation
47

Pathognomic feature of Spondyloarthropathy like PsA
Dactylitis
49
Which tissue to use to Dx GPA?
Kidney
50
Standard treatment regimen for GPA?
High dose oral glucocorticoids plus rituximab (preferred) IV pulse glucocorticoids Cyclophosphamide
51
Features of an inflammatory pain?
Night pain, morning stiffness and pain that improves with activity.
52
Evaluation of an inflammatory low back pain ( spondyloarthritis)
1. Compelling clinical picture 2. Pain radiograph of SI joint (may be normal for 1 to 2 yrs after symptoms develop) 3. HLA-B27 (positive test in background of compelling clinical picture, confirms the dx) 4. MRI of pelvis for SI inflammation (more sensitive than CT to detect SI inflammation) (If HLA is negative or in a patient with inflammatory LB ache and positive HLA but no other features of spondyloarthritis)
53
Reason for ANA as the initial test in evaluation of a suspected Rheumatologic Disease?
ANA is very sensitive but low specificity ( If ANA is negative, then further subserology testing is typically negative). Therefore if ANA is negative, then serology testing is not indicated. If ANA is positive, then specific subserologies are indicated on the basis of clinical scenario.
54
Anti DS DNA vs Anti Smith antibodies for SLE?
Anti DS DNA (95 % specific, 50-60% sensitive), found in more severe disease, especially KIDNEY DISEASE. Levels follow disease activity and useful to MONITOR drug therapy. Anti Smith- Most specific (99%) for SLE, low sensitivity. Levels do not correlate with disease activity.
55
3 FDA approved medications for Fibromyalgia
Pregabalin (starting 50/75 nightly titrating upto 225 BID) Duloxetine Milnacipran
56
What is DISH?
Diffuse idiopathic skeletal hyperostosis- Noninflammatory condition, can occasionally have elevated inflammatory markers, causes calcification and ossification of spinal ligaments (esp Anterior Longitudinal Ligament) and entheses ( tendon and ligament attached to bone), causing pain stiffness and reduced ROM. Imaging shows flowing linear calcification and ossification along anterolateral aspects of vertebral bodies. More common in Men > 45, most involve thoracic spine. It does NOT affect SI joint.
57
Chronic back pain and stiffness, DISH vs AS (Ank Spond)?
DISH- Men, > 45, SPARES SI (Prominently involves thoracic spine) AS- < 45, SI involvement
58
Most effective LSM in reducing patients’ risk of developing RA?
Smoking cessation. A dose dependent relationship exists between smoking and development of Seropositive RA. Smoking causes lung inflammation which activates enzymes such as peptidylarginine deiminase which deaminates arginine to form citrullinated peptides. These are presented as antigens by a shared epitope coded by HLA-D allele, leading to production of anti-CCP antibodies that could initiate inflammation by fixing complement in tissues.
59
Dx Photosensitive distribution of dermatomyositis rash on the face. Heliotrope rash over eyelids. Gottron papules on the elbows and knees. With normal CK and no muscle symptoms.
Amyopathic Dermatomyositis: Patients never develop muscle involvement, can be diagnosed with skin biopsy confirmation of Dermatomyositis in the setting of atleast 6 months without muscle involvement.
60
Photosensitive rash of dermatomyositis vs SLE?
Both can have similar facial rash and skin biopsy findings. SLE does not have Heliotrope rash or Gottron papules on hands, elbows and knees.
61
Differentials of Malar Rash?
SLE- Photosensitive, lacks heliotrope and gottron. Dermatomyositis- Photosensitive, characteristic Heliotrope rash and Gottron papule Rosacea- would not cause skin changes on extremities.
62
What to suspect in patients with Ank Spond who develop abdominal pain, diarrhea or change in bowel habits?
IBD- Crohn and UC occur with similar frequency. Occurs early in the course of disease, by 10 yrs of AS, the risk of IBD has returned to general population level.
63
Diagnostic criteria for IBS
Recurrent abdominal pain at least 1 day a week for 3 months, along with atleast 2/3 of : Pain related to Defecation Change in stool frequency Change in stool consistency
64
Lyme arthritis presentation and diagnosis?
LA is a late stage manifestation of lyme ds. Monoarticular, mostly knee. Suspect in pt with intreated or incompletely treated Lyme. Dx : All pt with LA should have positive results on ELISA and Western Blot confirmatory serologies. A second enzyme immunoassay can be used as a confirmatory test. Borrelia DNA can be detected by PCR in synovial fluid, but this test offers no advantage to Serologic testing.
65
Treatment of Lyme Arthritis?
28 days Doxycycline. 28 days of amoxicillin is an alternative first line therapy. For pts whose arthritis improves but does not completely resolve, a second 28 day course of the same antibiotic can be prescribed.
66
Treatment of persitent arthritis ( after 2x 28 days courses of Doxy) ?
Suggests Reactive Arthritis. Rheumatologist referral. Tx with HCQ or MTx.
67
Diagnostic feature of CPP crystal arthritis on plain XR?
Chondrocalcinosis (thin white line that tracks below the surface layer of cartilage, representing CPP deposition within cartilage)
68
Acute Gout vs CPP crystal arthritis
Gout typical joint involvement : knee with current or prior joint involvement of first MTP, forefeet, ankles and fingers. Acute episode lasts : 1-2 weeks. Crystals: Negatively Birefringent and needle shaped. CPP typical: Knee or wrist Acute episode lasts more than 2 weeks. Crystals: Positively birefringent and rhomboid.
69
When to consider TNFi or IL-17i in AS patients?
After failure of trial of atleast 2 NSAIDs for 2-4 weeks, or if intolerant to NSAIDs.
70
Name 3 TNFi?
Etanercept (a fusion protein) Adalimumab and Infliximab (monoclonal antibodies). Selection depend on comorbidities, such as Uveitis or IBD, where monoclonal antibodies would be more appropriate.
71
2 IL-17i?
Secukinumab Ixekizumab
72
2 Janus Kinase inhibitors?
Tofacitinib Upadacitinib
73
First, second, third and fourth line agents for AS?
1. NSAIDs 2. TNFi (after failure of NSAIDs) ( fusion protein vs monoclonal antibodies based on pt comorbidities) 3. IL-17i ( alternative to TNFi or when TNFi are contraindicated after failure of NSAIDs) 4. Janus Kinase inhibitors (only after TNFi or IL-17i have failed or are contraindicated)
74
Drug selection based on axial vs peripheral disease?
Non biologic disease modifying agents such as MTx or Sulfasalazine have no efficacy in axial disease and limited efficacy in peripheral disease. Treatment with Sulfasalazine is recommended primarily for pts with prominent peripheral arthritis and few or no axial symptoms and in these pts, it may be more effective than MTx.
75
DOC for Scleroderma Renal Crisis?
Captopril (IV ACEi that can be rapidly titrated due to short half life) BB may exacerbate Raynaud phenomenon and therefore be avoided in patients with Systemic Sclerosis.
76
