1
Q

What is the pathophysiology behind RA?

A

It is an autoimmune condition which occurs when there’s antibodies to a portion of the IgG known as RF and another for Anti-citrullinated cyclic peptide. There is a process of citrullination of self antibodies which in turn causes activation of t and b cells and this results in secretion of TNF and proliferation of synoviocytes. Which essentially block the cartilage from nutrients and results in death of the cartilage. Macrophages also cause increased activation of osteoclasts causing bone damage

Q

What are the investigations associated with RA?

A
  • RF and Anti CCP
  • FBC- can present with normocytic anaemia in chronic RA
  • WCC to rule out septic arthritis
  • X RAY
  • inflammatory markers
  • Hrct- high Res CT and Pulmonary function tests PFT

Q

Why do patients present with normocytic anaemia in RA??

A

Because they have chronic inflammation, therefore bone marrow lifespan is reduced

Q

Why do patients present with lung problems in RA?

A

It’s one of the most common extra articular signs of RA- it occurs because of the formation of Rheumatoid nodules in the lungs

Q

What is the treatment of RA?

A

DMARD monotherapy- methotrexate and hydroxychloroquine, sulfasalazine
Steroids- PO/IMA OR INTRARTICULAR
- control the symptoms with NSAIDS but give PPI cover
- if RA is persistent then consider biologics- like ANTI- TNF
- consider occupational therapy or physiotherapy

Q

Treatment of PMR?

A

Usually treat with Prednisolone-15mg daily- slowly taper off- rapid tapering causes symptom relapse- in this case give methotrexate

Q

Why is there an increased risk of CVD in SLE?

A

-Because the inside of vessels are damaged by inflammatory processes- causes coronary diseases.

53
Q

What are the risk factors of LUPUS?

A

-Being a woman - this makes you 9* more likely to develop LUPUS- increased levels of estrogens increase autoimmunity- estradiol increases the lifespan of autoreactive T and B -cells -therefore increases disease processes
-Being a person of colour- they also have a worse prognosis
-being on isoniazid, minocycline and TNF I
-UV light exposure

54
Q

Why does UV light increase your risk of SLE?

A

-it damages the DNA- causes mutations which makes it more immunogenic.

A
  • Symmetrical proximal weakness
    -Raised serum muscle enzymes
    -EMG-electromyography changes- measures muscle responses to nervous stimuli
    -Biopsy evidently shows myositis
    -Rash typical of dermatomyositis
    it is PM If 3/ the first 4

80
Q

What are the typical findings on investigation for PM/DM?

A

-can have raised inflammatory markers- but more often than not- normal inflammatory markers.
-Have raised ALT but normal liver enzymes- suggests enzymes being released from muscle breakdown
-Auto-antibodies raised- anti-jo1 anti-Mi2
-Anti-nuclear antibody positive
Myositis visible on MRI

81
Q

-Diffuse scleroderma:
rarer - but there is a higher risk of mortality- sudden onset skin involvement proximal to the elbow and knees
-Limited scleroderma:- this is when patients have had pre-existing raynauds for 10 years and have developed scleroderma- thickened skin and PA hypertension
CREST syndromw

woman
Cigarette smoking
excessive drinking
caucasian or south asian
calcium deficiency vit D def
Iatrogenic- corticosteroids

119
Q

What are the investigaations for Osteoporosis?

A

-DEXA
-T score if their T score is between -1 to -2.5 indicates osteoporosis
-look at their Z score- which compares their BMD to people of the same age and weight- if it is less than -2 then abnormal
-rib fractures, vertebral fractures and compression fractures without any cause- should spark curiosity

120
Q

What is the treatment for OSTEOPENIA?

A

-usually just lifestyle management:
-weight bearing exercises
-Vit D
-reducing alcohol and smoking
-Calcium supplements

121

1st line-bisphosphonates
2nd line- denosumab

- the aim is to decrease uric acid levels <360

FOR FLARES- TREATMENT SHOULD BE WITHIN 24 HOURS.

127
Q

What investigations should you do for gout?

A
