• Intimate contact between patients should be avoided as this carries a<br />

high risk of spread.<br />

• Nursing staff must take responsibility where young children are<br />

concerned with regard to the amount of socialising allowed (e.g. children<br />

who do not cover their mouth when coughing).<br />

Stenotrophomonas maltophilia<br />

This organism is becoming more prevalent among CF patients. There is<br />

conflicting evidence as to whether it is associated with a decline in lung<br />

function. Current opinion is that it does not. Therefore only those patients<br />

who are chronically infected AND have clinical deterioration should be<br />

treated with anti-Stenotrophomans therapy. This is usually with cotrimoxazole<br />

(depending on sensitivities). There is no evidence for cross<br />

infectivity and therefore additional strict isolation protocols are not necessary.<br />

Methicillin-resistant Staphylococcus aureus (MRSA)<br />

A small number of patients will be colonised with MRSA. If sputum is found<br />

to be positive for MRSA then the child must be swabbed according to the<br />

MRSA screening protocol. Nasal carriage is treated with Mupirocin. In<br />

addition, family members should be swabbed and treatment arranged if<br />

found to be positive.<br />

If MRSA is suspected to be causing symptoms then treat according to<br />

sensitivities. Consider nebulised vancomycin preceded by nebulised<br />

salbutamol. For acute exacerbations include either teicoplanin or vancomycin.<br />

Linezolid may become useful in the future but at present experience is<br />

limited.<br />

The hospital policy on MRSA must be followed. Patients should be seen last<br />

on ward rounds and in an isolation area in the outpatient department.<br />

Atypical Myocobacteria<br />

Consider treating the mycobacteria if patients do not respond to conventional<br />

antibiotic therapy. Treatment length should be 6 to 12 months.<br />

Aspergillus Fumigatus<br />

(see <strong>Section</strong> 2.5)<br />

2.2.2 Macrolides<br />

There is emerging evidence for the beneficial use of azithromycin in children<br />

with CF. In addition to the antibacterial properties it is thought that<br />

azithromycin may work by a variety of anti-inflammatory mechanisms.<br />
