Q

Outpatient CAP: not as severe/ no risk for MRSA/ PA- regimens

A

Look at comorbidity: chronic heart/ lungs, liver, kidney disease?, DM, Cancer?

NO Comorbidity:
Amoxicillin 1g TID for min 5 days
**Doxycycline 100mg BID for min 5 days **
.
Comorbidity:
Augmentin 500 mg TID + Azithromycin 500mg QD for 5 days (OR Doxycycline 100mg BID)
Levo 750mg or moxi 400mg QD for min 5 days
Cefpodoxime 200mg BID for min 5 days + Doxycycline 100mg BID

Q

FIRST questions to ask

A
  • DDI
  • Comorbidities
  • Alleriges
  • any kidney dysfuction
  • Were they recently hospitalized and given IV abx in the past 90 days? was patient from a SNF?
  • Any prior isolation of MRSA and/ or Pseudomonas aeruginosa from the resp tract within 1 years?

Q

Inpatient Non Severe CAP: No prior MRSA/PA insolation or hospitalization OR hospitalization+IV ABX are the only risk factor

A

Option 1: General Beta Lactam (Unasyn 3g Q6 or Ceftriaxone 1-2g QD) + Macrolide (Azithro 500mg QD or Clarithro 500mg BID)
.
Option 2: MONO therapy - Resp FQ: Moxi 400mg QD or Levo 750mg QD
.
HOWEVER…if severe CAP but no hopsital/ IV ABX OR MRSA/PA…do dual TX so option 1! or tion 2 + beta lactam

Q

UTI case example

syptomatic, afrebrile, +LE, nitrites, no urine susceptibilities back, female, not pregnant, amoxil and sulfa allergy, –> diagnosed with uncomplicated cystitis… CrCL 120ml/min - how would you say it

A

I would recommend macrobid 100 bid x5 days, no cross-reactivity in allergies present, no DDI, no evidence pyelo or other complications. I would also refer to ISDA guideline or AUA guideline for more information if needed.

Q

Why crystolloids > Collids ? for fulid resec?

A

Colloids
Potential longer intravascular retention time vs. crystalloids
 No evidence of reduced mortality compared with crystalloids;
benefits may exist with certain subsets of patients
 Hydroxyethyl starch: FDA warning for increased mortality, severe
renal injury and risk of bleeding – do not use in critically ill patients
 Dextrans: increased risk of anaphylaxis, may aggravate bleeding,
and cause renal dysfunction

Q

Other stuff to consider if patient has Sepsis

A

1. GLUCOSE CONTROL .. Hyperglycemia, hypoglycemia and glycemic variability are associated with increased mortality
We RECOMMEND initiating insulin therapy at a glucose level of ≥ 180 mg/dL (Typical target blood glucose range is 140-180 mg/dL for ICU/ med unit inpatient! )…from NICE-SUGAR Study
2. VTE PROPHYLAXIS
We RECOMMEND low molecular weight heparin (LMWH) over unfractionated heparin (UFH) for VTE prophylaxis

STEMI vs NSTEMI

A

STEMI: Complete blockage! More extensive damage. On EKG - ST is elevated
NSTEMI: Partal blockage, less damage, no ST elevation but can show ST depression or T wave inversion
.
Both will show an elevated level of troponin! this is a marker of cardiac injury

Q

More details/ cavets on P2Y12 Inhibitors

A
  • LD for Clopidogrel is 300-600mg but if undergoing PCI? then 600mg!
  • AVOID Parsugrel or Ticagrelor if CABG is likely
  • Prasugrel is for ACS with PCI; LD 60md and maintain with 10mg w/ASA…once PCI is planned give dose no later than 1 hr after PCI!
58
Q

STEMI/ NSTEMI: GP2B/3A Antagonist

A

They are option for medical management of ACS or patietn recieving a PCI (w or w/o stent). Abciximab is ONLY indicated for PCI! if used in PCI? it has to be given with heparin!
.
Typically these meds are not used for patients with NSTEMI…but can be if NSTEMI is unresponsive to conventional medical therapy, when PCI planned within 24 hrs… NOT RECCOMENDED FOR NSTEMI WITHOUT PCI!!!! …regarding abciximab…
.
However, Tirofiban and eptifibatide can still be used in NSTEMI without PCI ….
BUT a good rule of thumb : Glycoprotein IIb/IIIa inhibitors like are not routinely used in NSTEMI without PCI

59
Q

STEMI: Fibrinolytics

A

These medications break down clot! USED ONLY FOR STEMI. PCI is pref. but in situation where PCI is not avalible or there is a delay in getting pt to a cath lab, or there is a C/I to PCI (eg. cannot take dual antiplatlet, mutilple PCI restenosis/ bloackage even after multiple PCI, increased risk)..fibrinolytics are used!
.
C/I to fibrinolytics: active internal bleeding/ hx of recent stroke/ any prior ICH
.
1. Altaplase 100mg IV over 5 mins, 50mg over 30 mins, then 35mg over 1 hr (for those with 65kg and over!/ doing is different for kg less tahn 65!)\
2. Tenecteplase; many dosing but ranges from 30-50mg based on weight!

Q

Secondary prevention after ACS/MI

A
  1. ASA 81 mg forever
  2. P2Y12 Inhibitor: NonPCI: Clopidogrel or Ticagrelor + ASA for at least 12mts; PCI treated use tica, clopid, or prasugrel + ASA for at least 12 mts
  3. Nitroglycerin forever PRN

Heart Failure/Stroke Guideline

A

AHA/ACC

66
Q

Heart Failure: What is it/ what are the symptoms/ what are the 4 different stages

A

HF occurs when the heart is not able to supply O2 rich blood due to impaired ability of ventricle to either fill or eject blood. Most HF cases is due to damage for MI or long standing HTN. Symp: fluid overload and HIGH BNP (over 100 - streching of heart). HFrEF : less than 40% for LVEF
.
Stage A: no s/s of HF, no abnormal markers
Stage B: Pre HF. no sign/symp but has one of the following: stuctural issue, increase filling pressure, or abnormal markers
Stage C: Symptomatic HF
Stage D: Advance HF - interference with daily/ normal activity

67
Q

HF Stage 3 (HFrEF): medication for all patient

A
  1. ARNi > ACEi> ARB: note - there is a 36 hr washout period required when trasitioning form ACEi to ARNi

69
Q

HF: ARNi: info

A
  • Start low dose: 24/26mg BID and titrate as tolerated q 2wks for target dose of 97/103 mg BID … remember the wash out period (36 hrs) with ACEi! due to increased risk of angioedema!
  • Like ARBs and ACEi: monitor: Scr, BUN, electrolytes particularly K+ (hyperk!)
70
Q

Dosing for HF medication: B Blocker

A
  • ONLY 3 that are reccomended via guidelines for HF: Metoprolol Succ, Bisoprolol, Carvedilol
  • Metoprolol Succ - 12.5-25mg the titrate Q2wks to reach 200mg QD… DO NOT D/C suddenly! Need to taper off to avoid tachy, decrease dose if HR is less than 60
  • Carvedilol - 3.125mg BID titrate to 25-50mg BID TAKE WITH FOOD
    .
    Hold titration if HR <50bpm…consider dose decrease
71
Q

  • Avoid alcohol
  • Exercise regularly
80
Q

HIT - what is it?/ Guideline?

A

A rare but serious side effect to heparin. This occurs when heparin binds to a protein in the plt called PF4. This hen forms a complex whihc triggers your immune system to make antibody against it. The antibodies bind to the heparin-PF4 complex and leads to plt destruction = thrombocytopenia (<150K).
ASH guidelines

81
Q

Criteria for HIT (4 T’s)

A
  1. Thrombocytopenia (plt fall >50% -2 pts, fell 30-50% -1 pt)
  2. Time of plt fall (5-10 days - 2 pts, unclear 1 pt)
  3. Thrombosis (new thrombosis/ necrosis -2pts, unclear 1pt)
  4. Other possible causes of thrombocytopenia? (none - 2pts, possible 1pt)
    .
    4T scores should be confirmed by ELISA and Serotonin Release Assay
82
Q

Treatment and management of HIT

A
  • D/C All heparin product including LMWH
  • Select one of the following instead: Argatroban, bivalirudin, fondaparinux
    1. Argatroban (injectation direct thrombin inhibitor) - 2 mcg/kg
    2. Bivalirudin (inj direct thrombin inhibitor), typically reserved for PCI
    3. Fondaparinux (inj indirect factor Xa inhibitor)
83
Q

DKA - what is it?, Lab findings

A

Hyperglycemia crisis; insulin insufficency leads to dehydration + acidosis. W/o insulin, cells cannot take up / use glucose, thus the body shifts to alternative energy source. The body starts to break down fat thus ketone is release. Ketones are acidic! this this decreases the body’s pH.
.
Lab findings:
Blood glucose: over 250
pH: less than 7.3
Bicarb: < 18 (bicarb is basic so it is low in this case)
Anion Gap: >10 (normal is 7-9) (Na-Cl-HCO3 = anion gap)
Ketones: Positive

84
Q

Treatment/ Mangement of DKA

A
  1. Fluids: NS first hr, then NS or .45% NaCl until normalized, then after DKA resolve switch to dextrose
  2. K+ replacement: when acidosis restores, K+ will shift into cell leading to lower K+! the goal is 4-5meq/l…replace when K is < 5.2meg. Use 20-30 meq (IV or PO) K+ to replace. If K+ is < 3.3 DO NOT USE INSULIN!!!
  3. Sodium Bicarb (maybe - this is controversial)…if pH is very low.. <6.9. can use bicarb..if not we wil not use
  4. INSULIN with regular insulin. do 0.1 u/k bolus then 0.1 u/kg/hr continuous IV OR 0.14 u/kg/hr continnuous IV —- get glucose to less than 200 —– then we can decrease insulin to 0.05u/kg/hr. GOAL is to get blood glucoe 150-200, pH >7.3, Bcarb >18, and close anion gap <12.
85
Q

Infective Endocarditis: What is it? / who’s most at risk?/ Bugs?/ empiric regimen?

A

Infection of the inner tissue of the heart, typically in the heart valves. Pt’s with prosthetic heart valves, chronic IV drug users - are those most at risk. The 3 most common bugs: staphylococci, streptococci, and enterococci…IE is fatal if left untreated!!! Empiric tx usually involves vanco and ceftriaxone. Gentamicin is added to the regimen for synergy when the infection is more difficult to eradicate (ie such as prosthetic valve infections or when treating a more resistance organisms.

86
Q

Infective Endocarditis (IE): tx duration

A

4-6 weeks of IV abx. However if gentamicin is used, he duration of gebntamicin varies from 2-6 weeks

87
Q

If gentamicin is used for IE, what is the goal?

A

target peak: 3-4 mcg/ml and trough levels is < 1 mcg/ml

88
Q

When is rifampin used in IE/ what is it’s role?

A

Some bacteria form a biofilm, esp on prosthetic valves…thsi is hard for some abx to penetrate. Rifampin may be used in these cases of staphpylococcal prosthetic valve endocaditis due to its ability to treat organisms in a biofilm

89
Q

Infective Endocarditis Treatment: Viridan group streptococci

A
  • Penicillin G 3 g q6hrs OR

SSTIs

Nonpurulent (ex. Cellulitis, Necrotizing infection): Treatment for Severe Cases.. like nec fas (S. pyrogenes)

A

Severe: patient who did not response to oral abx, those with weak immune systems, those meeting SIRS crietria, or showing signs of deeper infection
.
EMPIRIC RX: Vancomycin (or linezolid) + Zosyn or meropenem, then get culture and susceptibility… following the results, the abx therapy should be adjusted.

97
Q

SSTIs

Purulent (Ex. Abscess, furuncel, carbuncle): Treatment for Mild cases

A

Mild: single abscess with no systemic signs: incision/ drainage Plus culture and susceptibility..and thats it

98
Q

SSTIs

Purulent (Ex. Abscess, furuncel, carbuncle): Treatment for Moderate case

A

Moderate: systemic signs or mul;tiple sites of infection: Perform I & D, culture the fliud and use oral abx that also covers MRSA:
- Bactrim DS 1-2 tabs PO BID OR

103
Q

Inpatient Glucose Control

Inpatient glucose control: if oral intake is adquate VS. Poor intake?

A

If oral intake is adequate, a regimen with basal, bolus (prandial), and correction doses (usually added to the mealtime bolus dose) is perferred.
.
Poor intake: a basal and correction dose strategy is reccomended

104
Q

Inpatient glucose control: What is correction dose ?

A

Correction dose insulin is given when BG is already high. Like sliding scale insulin, the insulin dose given will crrelate with the BG, on a scale . The difference is that the correction dose is designed for a specific patient - it’s based on the patient’s insulin sensitivity - which indicated how much the BG will drop with each unit of insulin

105
Q

Inpatient Glucose Control: Sliding Scale

A
  • <60mg/dL = HOLD INSULIN
  • 150-200 = 2 units
  • 200-250 = 4 units
  • 250-300 = 6 units
  • 300-350 = 8 units
  • 350-400 = 10 units
  • +400 = call MD
    .
    Rapid acting is is prefered (insulin lipro = humalog, insulin aspart = novolog
106
Q

Inpatient Glucose Control : starting a basal bolus regimen (outpt and inpt) rule of thumb for DM2 patient!!!

114
Q

Statin Algorithm Secondary Prevention

A

START ON HIGH INTENSITY STATIN! - if LDL > 70 on statin? …add Ezetimibe 10 mg QD… if LDL > 70 even on statin + ezetimibe? ADD P5CK9 inhibitor (for very high risk patients).

115
Q

What to do if patient is experiencing side effects/ muscle pain

A
  • Order CPK, vitamin D, and thyroid labs - all are associated with myalgia
  • Make sure it’s not sure to statin: working out?
    .
    Mild- Moderate symp: discontinue statin, check CPK. If CPK is greater than 10? consider other therapy: Ezetimibe 10 mg Q. If under 10? wait for resolution of symp and start on lower dose of same statin.
    .
    Severe. D/C statin. risk vs benefit assessment.
116
Q

What to consider first when evaluating patients with DM?

A
  • annual eye and foot exam
  • need to add statin: mod- high intensity depending on risk
  • Assess HTN - if hyperalbuninuria * 2 time will need to be on ACEi or ARB
  • make sure patient has DM testing supplies (monitor, test stripes, lancets)
117
Q

DM: first line consideration?

A

First-line pharmacotherapy (metformin or other agents) should be selected based upon patient-specific factors (e.g., glycemic goals, cardiorenal risk, comorbidities, cost and access). Consider combination pharmacotherapy at initiation if A1C ≥1.5% above target goal

118
Q

Glycemic Goals

A

Most patients: A1C: <7.0; Preprandial 80 - 130mg/ dL; 2 hrs after meal <180 mg/dL

119
Q

DM: Step 1: Established/High-Risk of ASCVD, Heart Failure, or Chronic Kidney Disease? Recommended independent of baseline A1C, target A1C goal, or use of metformin

A

1.) ASCVD: GLP-1 RA or SGLT2i with proven CVD benefit… If A1C above target (wait like 3 months to assess) use both agents!
.
2.) Heart Failure: SGLT2i with HF benefit
- Avoid TZDs
- Avoid saxagliptin
.
3.) Chronic Kidney Disease (On maximally tolerated ACEi/ARB): SGLT2i with primary evidence for reducing CKD progression! … if A1C still above goal? add on GLP1 RA

120
Q

DM: GLP1 RA and the benefits

A

FDA approved CVD AND Renal benefit:
* dulaglutide (trulicity) - 0.75 mg once weekly, then 1.5mg max
* liraglutide (victoza/ saxenda) 0.6mg once daily x1 week, then increase to 1.2 mg once daily
* semaglutide (SUBQ) -Initial: 0.25 mg once weekly for 4 weeks, then increase to 0.5 mg once weekly - Ozempic
