Q

PRE-RENAL PROTEINURIA…

= due to WHAT?

2 examples?

how do we RESOLVE this proteinuria?

how should we ASSESS this?

A

= due to ABNORMAL PLASMA CONTENT of PROTEINS that CAN TRAVERSE GLOMERULAR CAPILLARY WALLS

2 examples of these proteins?
1. NORMAL PROTEIN that is USUALLY NOT IN BLOOD = Hb or MYOGLOBIN
2. ABNORMAL PROTEIN like BENCE-JONES in MULTIPLE MYELOMA

RESOLUTION occurs with CONTROL & REMISSION of PRIMARY DZ

ASSESS this if we see PROTEINURIA & should see ANEMIA along with ABNORMAL PROTEINS IN BLOOD (HEMOGLOBIN, MYOGLOBIN)

Q

how do we DIAGNOSE PROTEINURIA? give 3 diagnostics

also include PARAMETERS

which one can be used if DIPSTICK IS NEGATIVE?

which one is the GOLD STANDARD to determine the MAGNITUDE of PROTEINURIA?

only do these tests WHEN..

A
  1. DIPSTICK
    –> URINE ALBUMIN + at 0.3 g/L
    –> results should ALWAYS correlate with USG
  2. MICROALBUMINURIA ASSAY
    –> detects >0.01 to <0.3 g/L
    –> detects VERY SMALL CHANGES IN PROTEIN to check for animals that you PREDICT WILL BECOME PROTEINURIC but ARE NOT YET ON DIPSTICK
  3. URINE PROTEIN:CREATININE RATIO (UPC)
    –> MAGNITUDE of/QUANTIFY proteinuria

only do these tests WHEN WE ARE SURE THERE’S NO PRE- OR POST-RENAL COMPONENT, so URINE SEDIMENT/CULTURE IS NEGATIVE because can SKEW RESULTS

2. DIET CHANGE
3. MEDICAL MANAGEMENT

38
Q

in PROTEINURIC, NON-AZOTEMIC dog…

a RENAL DIET includes WHAT 3 THINGS?

what MEDICATION can this be combined with?

what 2 things can be IMPROVED?

however, we should NOT start animal on the RENAL DIET if…

A

RENAL DIET…
1. MODIFIED or LOWER PROTEIN

  1. REDUCED SODIUM CONTENT to help with NEPHROTIC SYSTEM & HYPERTENSION
  2. POLYUNSATURATED FATTY ACIDS with ratio of OMEGA 6:OMEGA 3: close to 5:1
    –> reduces PROTEINURIA, INFLAMMATION & VASOCONSTRICTION
    –> INCREASE GFR

can combine with BENAZEPRIL

RENAL DIET + BENAZEPRIL = CONTROL PROTEINURIA & SYSTOLIC BP

however, we should NOT start animal on the RENAL DIET if NOT EATING AT ALL, ESPECIALLY IN CATS!

39
Q

RAAS control…

how does RAAS system basically work? (4, end with OVERALL what it does)

2 types of drugs & what part they act on?

OVERALL, both drugs will…

A

how does it basically work?
1. ANGIOTENSIN transformed not ANGIOTENSIN I via RENIN

  1. ACE converts ANGIOTENSIN I to ANGIOTENSIN II
  2. ANGIOTENSIN II binds to ANGIOTENSIN RECEPTOR TYPE 1 to MAKE ADH
  3. overall helps to INCREASE INTRA-GLOMERULAR PRESSURE

ACE-inhibitors = ENALAPRIL/BENAZEPRIL that blocks ACE (angiotensin I to II)

ARB = TELMISARTAN that blocks ANGIONTENSIN RECEPTOR TYPE I to PREVENT PRODUCTION OF ADH

OVERALL, both drugs will DECREASE INTRA-GLOMERULAR BLOOD PRESSURE so that PROTEINURIA DECREASES

40
Q

ANGIOTENSIN-CONVERTING ENZYME INHIBITORS (ACE INHIBITORS)

this is the ___ option to TREAT ___ & ____ as a ____-____ THERAPY

  1. PREVENT BREAKDOWN of BRADYKININ to ALLOW EFFERENT ARTERIOLAR VASODILATION

2 drug examples?
1. ENALAPRIL (excreted by KIDNEY)
2. BENAZEPRIL (excreted by BILIARY system)
–> ARE THE SAME FUNCTIONALLY

we SHOULD NOT use ACE-INHIBITORS if..
1. patient NOT WELL-HYDRATED
2. if patient has AKI or ADVANCED AZOTEMIA/RENAL DZ

41
Q

ANGIOTENSIN-RECEPTOR BLOCKERS (ARBs)

mechanism of action?

what is the NAME of the drug?

helps to treat ____ ____ ____

A

mechanism = BLOCKS ANGIOTENSIN II TYPE I RECEPTOR

drug = TELMISARTAN

helps to treat PERSISTENT RENAL PROTEINURIA

42
Q

should we use COMBINED therapy of ACE-INHIBITORS & ANGIOTENSIN II RECEPTOR BLOCKERS (ARBs)?

NOT AS A FIRST LINE, usually start with ACEi, then consider TELMISARTAN if ACEi NOT WELL TOLERATED OR EFFECTIVE in REDUCING PROTEINURIA

43
Q

ALDOSTERONE RECEPTOR ANTAGONIST…

drug name?

we should ONLY give this when…

A

drug name? = SPIRONOLACTONE

we should ONLY give this when ACEi or ARB is NOT EFFECTIVE or NOT WELL TOLERATED in PATIENT

44
Q

what ELECTROLYTE derangement should we MONITOR when administering RAAS INHIBITION THERAPY?

what is the NUMERICAL PARAMETER we should look out for?

if we see this, what 4 things can we do?

A

ELECTROLYTE DERANGEMENT = check for HYPERKALEMIA

PARAMETER = i>6 mmol/L

if we SEE HYPERKALEMIA >6 mmol/L, then…

  1. ECG MONITORING for BRADYARRHYTHMIAS
  2. REDUCE ACEi or ARB dose
  3. STOP SPIRONOLACTONE
  4. consider INTESTINAL POTASSIUM BINDER
45
Q

–> if a PARAMETER is ABNORMAL?

after 2-4 WEEKS, what 4 things should we evaluate?
–> if DOING WELL? by what numerical parameters?
–> if NOT DOING WELL? by what numerical parameters?

after 4-6 WEEKS, what 4 things should we evaluate?
–> if DOING WELL? by what numerical parameters?
–> if NOT DOING WELL? by what numerical parameters?

A

start with ACEi (BENAZEPRIL or ENALAPRIL)

after 1-2 WEEKS = evaluate SERUM CREATININE, POTASSIUM & BP
–> if all parameters within TOLERABLE limits, continue
–> if any parameters ABNORMAL, then STOP ACEi & try ANOTHER THERAPY like ARB

after 2-4 WEEKS = evaluate SERUM CREATININE, POTASSIUM, BP & UPC
–> if UPC <0.5 or REDUCTION >50% = DO NOT DO ANYTHING
–> if UPC >0.5 or REDUCTION <50% & NORMAL K/BP = can INCREASE ACEi dosage & RE-EVALUATE at 4-6 WEEKS

after 4-6 WEEKS = evaluate SERUM CREATININE, K, BP & UPC
–> if UPC <0.5 or >50% reduction = DO NOTHING
–> if UPC >0.5 or <50% reduction WITH ACEi dosage change = INCREASE ACEi DOSAGE & potentially ADD TELMISARTAN (ARB)

46
Q

what are the 4 TARGET ORGANS for DAMAGE in HYPERTENSION?

how does ONE RELEVANT organ damage manifest? (3)

what is one of the most COMMON drugs we use to MANAGE HYPERTENSION?

–> how does it affect ABOVE ORGAN?
–> what OTHER DRUG must it be COMBINED WITH?

A
  1. KIDNEY
  2. EYES
  3. BRAIN
  4. CARDIOVASCULAR SYSTEM

on KIDNEY = TARGET ORGAN DAMAGE by HYPERTENSION PROGRESSIVE DECLINE IN RENAL FUNCTION

  1. INCREASED AZOTEMIA
  2. WORSE PROTEINURIA
  3. MORE FREQUENT UREMIC CRISES

AMLODIPINE used for HYPERTENSION in KIDNEY!
–> CALCIUM-CHANNEL BLOCKER
–> works to VASODILATE AFFERENT ARTERIOLE
–> must be COMBINED with ACEi to MAKE SURE WE’RE NOT INCREASING INTRAGLOMERULAR PRESSURE

47
