Rheumatoid arthritis is an autoimmune disease that causes inflammation of the joints, resulting in pain, swelling, stiffness and destruction of cartilage and bone. It most commonly affects small joints in the hands and feet. Conventional treatments include NSAIDs, disease-modifying anti-rheumatic drugs like methotrexate, and corticosteroids. However, these may have side effects or lose effectiveness over time. Biological therapies targeting cytokines like TNF-α have significantly improved treatment outcomes, with anti-TNF agents infliximab, etanercept and adalimumab being widely used options.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
2. Arthritis
“arthro” = joint
“itis” = inflammation
“Arthritis can affect babies and children, as well as people in the
prime of their lives”
• Rheumatoid arthritis is an autoimmune disease in which the
normal immune response is directed against an individual's own
tissue, including the joints, tendons, and bones, resulting in
inflammation and destruction of these tissues.
• Commonest inflammatory joint disease seen in clinical
practice affecting approx 1% of population.
• Characterized by persistent inflammatory synovitis leading to
cartilage damage, bone erosions, joint deformity and disability.
3. Anatomy of the Joint
Articular/hyaline cartilage
-acts as a shock absorber
- allows for friction-free movement
- not innervated!
Synovial membrane/synovium
-secretes synovial fluid
-nourishes cartilage
-cushions the bones
4. Overview
Age: Any age, commonly 3rd to 6th decade
Female: male 3:1
pattern of joint involvement could be:-
1) Polyarticular : most common
2) Oligoarticular
3) Monoarticular
Morning joint stiffness > 1 hour and easing with physical activity is
characteristic.
Small joints of hand and feet are typically involved.
6. Articular manifestation
Pain and swelling in
affected joint
aggravated by
movement is the most
common symptom.
Morning stiffness ≥1
hr
Joints involved -
7. Relative incidence of joint
involvement in RA
MCP and PIP joints of hands & MTP of feet 90%
Knees, ankles & wrists- 80%
Shoulders- 60%
Elbows- 50%
TM, Acromio - clavicular & SC joints- 30%
8. Joints involved in RA
Don’t forget the cervical spine!!
Instability at cervical spine can lead to
impingement of the spinal cord.
Thoracolumbar, sacroiliac, and distal
interphalangeal joints (DIP)of the hand are
NOT involved.
13. Extra-articular manifestations
Present in 30-40%
May occur prior to arthritis
Patients that are more likely to get are:
High titres of RF/ anti-CCP
HLA DR4+
Male
Early onset disability
History of smoking
16. Rheumatoid nodule
•These are small subcutaneous nodules
present at the extensor surfaces of hand,
wrist, elbow and back in rheumatoid
arthritis patients.
•Characteristics feature of rheumatoid
arthritis
•A marker of disease activity
•Can be present even if other features of
rheumatoid Arthritis are absent
18. Rheumatoid Factor (RF)
Antibodies that recognize Fc portion of IgG
Can be IgM , IgG , IgA
85% of patients with RA over the first 2 years become RF+
• A negative RF may be repeated 4-6 monthly for the first two year of
disease, since some patients may take 18-24 months to become
seropositive.
• PROGNISTIC VALUE- Patients with high titres of RF, in general,
tend to have POOR PROGNOSIS, MORE EXTRA ARTICULAR
MANIFESTATION.
19. Causes of positive test for RF
Rheumatoid arthritis
Sjogrens syndrome
Vasculitis such as polyarteritis nodosa
Sarcoidosis
Systemic lupus erythematosus
Cryoglobulinemia
Chronic liver disease
Infections- tuberculosis , bacterial endocarditis, infectious
mononucleosis, leprosy, syphilis, leishmaniasis.
Malignancies
Old age(5% women aged above 60)
20. Anti-CCP

EARLY AGGRESSIVE TREATEMNT
32. Treatment modalities for RA
NSAIDS
Steroids
DMARDs
Immunosuppressive therapy
Biological therapies
Surgery
33. NSAIDS
Non-Steroidal anti-inflammatories (NSAIDS)
/ Coxibs for symptom control
1) Reduce pain and swelling by inhibiting COX
2) Do not alter course of the disease.
3) Chronic use should be minimised.
4) Most common side effect related to GI tract.
34. Corticosteroids in RA
Corticosteroids , both systemic and intra-articular are
important adjuncts in management of RA.
Indications for systemic steroids are:-
1. For treatment of rheumatoid flares.
2. For extra-articular RA like rheumatoid vasculitis and
interstitial lung disease.
3. As bridge therapy for 6-8 weeks before the action of
DMARDs begin.
4. Maintainence dose of 10mg or less of predinisolone daily
in patients with active RA.
5. Sometimes in pregnancy when other DMARDs cannot be
used.
35. Disease Modifying Anti-rheumatic Agents
Drugs that actually alter the disease course .
Should be used as soon as diagnosis is made.
Appearance of benefit delayed for weeks to
months.
NSAIDS must be continued with them until true
remission is achieved .
Induction of true remission is unusual .
36. DMARDs

39. When to start DMARDs?
DMARDs are indicated in all patients with RA who
continue to have active disease even after 3 months
of NSAIDS use.
The period of 3 months is arbitary & has been
chosen since a small percentage of patients may go
in spontaneous remission.
The vast majority , however , need DMARDs and
many rheumatologists start DMARDs from Day 1.
40. How to select DMARDs?
There are no strict guidelines about which DMARDs
to start first in an individual.
Methotrexate has rapid onset of action than other
DMARD.
Taking in account patient tolerance, cost
considerations and ease of once weekly oral
administration METHOTREXATE is the DMARD
of choice, most widely prescribed in the world.
41. Should DMARDs be used singly or
in combination?
Since single DMARD therapy (in conjunction with
NSAIDS) is often only modestly effective , combination
therapy has an inherent appeal.
DMARD combination is specially effective if they include
methotrexate as an anchor drug.
Combination of methotrexate with leflunamide are
synergestic since there mode of action is different.
42. Limitations of conventional DMARDs
1) The onset of action takes several months.
2) The remission induced in many cases is partial.
3) There may be substantial toxicity which
requires careful monitoring.
4) DMARDs have a tendency to lose effectiveness
with time-(slip out).
These drawbacks have made researchers look
for alternative treatment strategies for RA- The
Biologic Response Modifiers.
43. Immunosuppresive therapy
Agent Usual dose/route Side effects
Azathioprine 50-150 mg orally GI side effects ,
myelosuppression, infection,

.
44. BIOLOGICS IN RA
Cytokines such as TNF-α ,IL-1,IL-10 etc. are key
mediators of immune function in RA and have
been major targets of therapeutic manipulations in
RA.
Of the various cytokines,TNF-α has attaracted
maximum attention.
Various biologicals approved in RA are:-
1) Anti TNF agents : Infliximab Etanercept Adalimumab
2) IL-1 receptor antagonist : Anakinra
3) IL-6 receptor antagonist : Tocilizumab
4) Anti CD20 antibody : Rituximab

48. How to monitor Tt in RA?
Disease activity is assesed by several parameters…
• Duration of morning stiffness
• Tender joints count
• Swollen joints count
• Observer global assessment
• Patient global assessment
• Visual analogue scale for pain
• Health assessment questionnaire
• ESR
• NSAID pill count etc…
• Patient on MTX, SSZ or leflunamide show clinical improvement in 6-8 wks.
• Patient should be observed for 6 months before declaring a DMARD ineffective.
49. How long should Tt. be continued?
Once remission is achieved , maintenance dose for
long period is recommended.
Relapse occurs in 3-5 months (1-2 months in case of
MTX) if drug is discontinued in most instances.
DMARDs are discontinued by patients because of
toxicity or secondary failure(common after 1-2 yrs)
and such patients might have to shift over different
DMARDs over 5-10 yrs.
Disease flare may require escalation of DMARD dose
with short course of steroids.
50. Surgical Approaches
Synovectomy is ordinarily not recommended for patients with
rheumatoid arthritis, primarily because relief is only transient.
However, an exception is synovectomy of the wrist, which is
recommended if intense synovitis is persistent despite medical
treatment over 6 to 12 months. Persistent synovitis involving
the dorsal compartments of the wrist can lead to extensor
tendon sheath rupture resulting in severe disability of hand
function.
Total joint arthroplasties , particularly of the knee, hip, wrist,
and elbow, are highly successful.
Other operations include release of nerve entrapments (e.g.,
carpal tunnel syndrome), arthroscopic procedures, and,
occasionally, removal of a symptomatic rheumatoid nodule.
