What to do when
nothing can be done?
Fabiola Caracseghi
Case 1: 16 year-old girl
No significant family history, no consanguinity.
Several severe infections:
3 m: Pneumocystis jirovecii pneumonia MV 1 m.
2 yo: Acinetobacter anitratus lung abscess.
4 yo: multiple pneumatocoeles. Recurrent hemoptysis.
Lung Aspergilloma (LIL).
14 -16 yo: recurrent hemoptysis 2 life-threatening episodes
2 arterial embolizations.
Oral and ophthalmic HSV1 infection and cutaneous candidiasis.
3 years:
IgE: 5040 U/ml.
R382Q heterozygous mutation in STAT3 gene
Hyper IgE syndrome
Current situation
Multiple bilateral
pneumatocoeles and
bronchiectasis.
Prophylaxis: TMP-SMX and
itraconazole.
Monthly IVIG treatment.
Moderate restrictive
ventilatory alteration.
Recurrent hemoptysis
Will the next one be fatal?
What can be done?
Management of HIES
Difficult
Incomplete understanding of the pathophysiology
Mainly supportive
Early diagnosis
Prevention of severe systemic infections and
aggressive treatment when they occur
Control of the pruritus and eczematoid dermatitis
Management of HIES
Skin care
antibiotic/antimycotic treatment of infections cold abscesses!
Surgical drainage of abscesses.
Vigilance for complications (osteomyelitis).
Prompt
Management of pulmonary complications
ill but well-feeling Active suspicion needed!
Aggressive high-dose iv antibiotic treatment.
Empirical treatment active against S. aureus, H. influenzae, S. pneumoniae.
Cysts, bronchiectasis, pneumatocoeles:
Severely
Frequent bacterial/fungal superinfection
Lung resection – difficult:
impairment of expansion of residual lung tissue
involvement of other lobes
contamination of the pleural space
Immunomodulation
Immunomodulation in HIES
Poorly studied
Not enough evidence to give recommendations
IVIG
Levamisole
γ-IFN
H2-antagonists
Ascorbic Acid
CyA
Omalizumab
Rituximab
BMT
IVIG
The most frequently used.
HIES: impairment AB formation, especially against encapsulated
organisms.
May decrease the number of infections.
May influence IgE levels:
increased/induces Ig catabolism.
IgE neutralization via an anti-idiotype network.

IFN-gamma
Studies in mice: inhibits IL-4-induced IgE synthesis.
Improves the chemotaxis of human neutrophils in vitro.
May lower IgE levels.
May decrease respiratory symptomatology.
Can trigger autoimmune cytopenias, such as thrombocytopenia.
Consider in patients with very serious infections, such as aspergillosis.

transplantation

BMT does not cure the immunological
features of HIES syndrome.
What can be done?
Surgical resection:
High
risk of uncotrolled bleeding.
Multiple areas of affectation.
High risk of recurrence after surgery.
Haematopoietic
progenitors transplantation:
Impairment of expansion of residual lung tissue.
Does not cure the disease.
Does not solve the hemoptysis.
High risk of oportunistic infection after immunosupression.
Lung transplantation:
High risk of oportunistic infeccion after the required immunosupression.
Not reported.
IFN-gamma, CyA:
To
be considered.
Will not cure the hemoptysis.
Case 2: 18 year-old male
No significant family history, no consanguinity.
Typical / severe infections:
Cutaneous abscess post DTP immunization
Salmonellosis
2 yo: Bilateral necrotizing Rhodococcus equi pneumonia right
pneumectomy
14 years: pneumonia by Burkholderia cepacia MV and HFV
2 years
•Oxydation test: 0%
•Genetic study: C1028T mutation in CYBB
gene, changing the CCT codon for Pro-339 in
gp91-phox into a CAT codon for Histidine
X-linked CGD
Mother carrier of the mutation
Current situation
Subcutaneous γ-IFN 3 times/week.
Prophylaxis: TMP-SMX, itraconazole.
No need for domiciliary O2-therapy.
Dyspnea on moderate exertion.
His residual lung capacity only depends on his left superior lobe.
Current situation
Subcutaneous γ-IFN 3 times/week.
Prophylaxis: TMP-SMX, itraconazole.
No need for domiciliary O2-therapy.
Dyspnea on moderate exertion.
His residual lung capacity only depends on his left superior lobe.
Will the next pneumonia be fatal?
What can be done?
Management of CGD
Antimicrobial prophylaxis:
Antibacterial: TMP-SMX
Antifungal: itraconazole/posaconazole
Treatment of acute infections:
Empirical: ciprofloxacin, teicoplanin, linezolid
Antifungal: voriconazole, posaconazole
Surgery
White cell transfusions
Immunomodulatory: IFN-gamma
Inflammatory complications:
Prednisolone, 5-aminosalicylate, azathioprine, infliximab.
CURE OF THE DISEASE:
•Haematopoietic stem cell transplantation
•Stem cell gene therapy
Haematopoietic stem cell transplantation
CGD: stem cell disease can be cured by HSCT.
The decision should be made early in life.
No predictive parameters based on individual clinical course.
Uncomplicated CDG NOT an indication for HSCT.
Most useful:
Recurrent serious infections despite correct prophylaxis
Severe steroid-dependent/resistant inflammatory complications

Stem cell gene therapy
CGD: good candidate: single gene defects.
Metabolic genes not involved in cell proliferation.
10% functional correction is enough.

Difficulties:
become feasible to overcome
Lack of a life-threatening
selective growth advantage
of gene transduced cells
infections.
(Malech 2004, Barese 2004)
Solutions: Submyeloablative conditioning (Ott, 2006)
Risks:
Insertional
Cure ofmutagenesis
CGD by gene therapy alone:
Transactivation of proto-oncogenes from retrovirus-mediated gene
still a distant goal.
therapy
Solutions:
Self-inactivating vectors (Modlich, 2006)
Lentiviral vectors (Roesler, 2002)
What can be done?
Haematopoietic progenitors transplantation:
Curative treatment.
No HLA-identical sibling donor.
Rejected for a URD transplantation because of high
risk of death if lung complications occur.
Next pneumonia:
Could benefit from gene therapy.
Further experience needed.
