Superinfection, Sepsis, Notifiable diseases

Question 1

Superinfection

Answer 1

Basc a infection on another infection.
EXAMPLE: PT has UTI - Get trimethoprim - then PT gets oral thrush - this is now a superinfection.

More common with broad spec bacteria as they decrease/kill good and bad bacteria = higher vulnerability of fungal infection/Antibiotic associated colitis.

Knowing narrow specs makes its easier to know broad spec.

Acronym for narrow spec antibiotic: (most common only)
TV & PC
Teicoplanin
Vancomycin
Penicillin G (Benzyl P)/ Phenoxy
Clindamycin

• Above list isn’t exhaustive

Broad spec antibiotics
Aminoglycosides
Macrolides (azithro, erythro etc)
Carbapenems (meropenem etc)
Cephalosporins
Tetracyclines
Quinolones
Ampicillin
Amoxicillin
Chloramphenicol

Question 2

Sepsis & Septicaemia

Answer 2

Septicaemia - Restricted to the blood.
- Caused y bacteria, fungi or virus

Sepsis - All organs can be affected.
- Life threatening, WHOLE body affected. Body reaction to severe infection

Septicaemia can lead to sepsis. Sepsis more severe.

Sepsis symptoms (EXAM Q)
S - Shivering, fever or very cold
E - Extreme pain or general discomfort
P - Pale or discoloured skin
S - Sleepy, lethargic
I - “I feel like I might die”
S - SOB

Sepsis in children (EXAM Q)
Very high/low temp
No urine in the last 12 hrs
Vomiting
Breathing fast
Non blanching rash (like meningitis)
Blue/Pale skin or lips (cyanosis)
Babies - High pitch cry/Lethargic

NON blanching = Rash dont disappear when glass is put on it.

Sepsis Treatment
Give broad spec antibiotics at MAX dose ideally within 1 hr to reduce risk of severe illness or death for PTs at high risk
Empirical IV treatment needed then use local formulary with national guidelines.
PRSC:
- IV Benzylpenicillin (Penicillin G) in community.
- IV Ceftriaxone in hospital

Monitor PTs at high risk no less than every 30 mins.

Septicaemia (community acquired)
- Broad spec antipseudomonal penicillin OR broad spec Cephalosporin
- MRSA sus + Vancomycin or Teicoplanin
- Anaerobic sus + Metronidazole to cephalosporin
- Other resistant microbe sus use more broad spec beta lactam (eg meropenem)

Broad spec antipseudomonal penicillin eg Piperacillin + tazobactam, Ticarcillin + Clavulanic acid

Septicaemia (Hospital acquired)
Broad-spec antipseudomonal beta-lactam (Above, meropenem or Ceftazidime)
MRSA/Anaerobic sus same advice as ABOVE

Septicaemia with vascular Catheter
Vancomycin or Teicoplanin
- Gram -ve sus + Broad-spec antipseudomonal beta-lactam.

Meningococcal septicaemia
Single dose of Penicillin G B4 urgent hospital transfer as long as transfer not delayed
ALT cefotaxime ALT Chloramphenicol

To remove nose carriage - Cipro, Rifampicin or Ceftriaxone

Question 3

Notifiable diseases (EXAM Q)

Answer 3

Notifiable disease - A very contagious disease - need to notify some1 of it. So there’s a public health risk i.e. COVID
