[PAGID] Necrotisin pneumonia in a CGD patient

[Chinen, Javier]

This is an expected clinical scenario in CGD. Consider Fungitell (BDGlucan), and aspergillus galactomannan (platelia). Major problems with sensitivity and specificity, as the tests perform worse in CGD than in neutropenic patients (unpublished experience), but definitive positives are helpful.

Subject: [PAGID] Necrotisin pneumonia in a CGD patient



Dear colleagues,



We are actually worried about a 3 yo boy who was diagnosed of CGD 2 years ago due to family history (his brother suffered from disseminated aspergilosis). He has been doing well until May, when he was admitted to another centre in Spain due to a left lung necrotising pneumonia. Despite several antibacterial and antifungal courses, the patient is worsening and a lung CT performed a week ago showed invasion of the 6th rib and pericardium.

The patient is currently receiving meropenem, rifampin, cotrimoxazole, clarithromycin, voriconazole and caspofungin in order to treat Nocardia, Actinomyces, Rhodococcus and IFI.

During admission two BAL and one open lung biopsy have been performed and cultures (bacteria, mycobacteria, fungi) have repeteadly yielded negative results as PCR to Mycobacterium tuberculosis complex and Aspergillus sp. Our pathologist has reported the presence of granulomata and severe necrosis.

We are waiting for surgical resection of the lesion and we wonder what microbiological tests you would consider in order to achieve an aetiological diagnosis if possible.





Many thanks for your time,



Yours,



Pere Soler Palacín
