Hyperglobuliaemia

18
Q

How do you treat vasculitis

A

Steroid - pred
Immunosuppression - Cyclophosphamide

Plasma exchange if renal failure / anti-GBM

19
Q

What risks of cyclophosphamide

A

Bladder TCC

20
Q

What do you do if symptomatic on cyclophosphamide

A

Refer to urology if haematuria / cystitis

21
Q

Complications of vasculitis

A

Progress to ESRF

22
Q

What is MM

A

Monoclonal proliferation of plasma cell

Produce excess of Ig and light chains

23
Q

What are the symptoms of MM

A
Anaemia
Back pain
Weight loss
Fractures
Infection
Cord compression
Elevated ESR
Hypercalcaemia 
Renal failure
24
Q

How do you Dx MM

A
Bone marrow aspirate = diagnostic 
Serum paraprotein / light chain
Electrophoresis + immunofixation 
Urinary bench jones protein
Skeletal survey
25
Q

What does aspiration show

A

> 10% clonal plasma cells

26
Q

How do you treat

A

Fluid + biphosphonate for hypercalcaemia
Plasma exchange to remove light chains
Myeloma Rx

27
Q

Why should you be careful with biphosphonates

A

if eGFR <30

28
Q

What causes renal failure in MM

A
Cast nephropathy - Ig gets stuck in tubules
Light chain nephropathy
Amyloidosis
Hypercalcaemia
Hyperuricaemia
29
Q

What is amyloidosis

A

Deposits of amyloid

Affects any organ

30
Q

What causes

A

Idiopathic
2d to infection / solid organ tumour / lymhpoma
MGUS

31
Q

How do you Dx amyloidosis

A

Biopsy of area affected

32
Q

How does kidney affect CVS

A

Hypertension
Fluid overload
Calcification of vessel

33
Q

How does CVS disease affect kidney

A
Hypertension = CKD
Atheroembolism 
Warfarin
Vascular procedures
Nephrotoxic drugs
34
Q

When would you use diuretics in kidney disease

A

If HF is the reason for the kidney issue

35
Q

How should you investigate systemic disease

A
Urinanalysis
Urine culture
Bloods 
Specific - ANA/ ANCA / complement
Blood culture
CXR / USS / CT / ECHO
Biopsy
