Safety and Efficacy of Hydroxychloroquine in Children's Interstitial Lung Diseases With Genetic Causes: a Randomized Controlled Study

The aim of this proposed study is to evaluate the efficacy and safety of hydroxychloroquine (HCQ) in children's interstitial lung diseases(chILD) with genetic causes. This study is a randomized controlled clinical trial.

Detailed Description

Children Interstitial lung disease (chILD) is a heterogeneous group of rare respiratory disorders of known and unknown etiologies that are mostly chronic and associated with high morbidity and mortality. Genetic factors are important contributors to chILD. Genetic variations have been mainly described in genes encoding (or interacting with) the surfactant proteins (SP): SP-C (SFTPC) and the ATP-binding cassette-family A-member 3 (ABCA3) (ABCA3), and less frequently in the genes encoding NKX homeobox 2 (NKX2)-1 (NKX2-1), SP-B (SFTPB), SP-A (SFTPA) and other genes.

Hydroxychloroquine has been reported to be useful in cases or case series of chILD including those with genetic causes alone or in combination with systemic steroids. However, the efficacy is highly variable and no randomized controlled study has been reported. The study is a randomized controlled investigation aiming to evaluate the efficacy and safety of hydroxychloroquine in chILD with genetic causes.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Hydroxychloroquine
Hydroxychloroquine in a dose of 10 mg/kg*d, p.o., bid for 12 months. The maximum daily dose is 400mg.
Drug: Hydroxychloroquine
Hydroxychloroquine Sulfate is an anti-malarial and anti-rheumatic drug. hydroxychloroquine has been reported to improve the clinical status of chILD cases wtih genetic causes. The exact mechanism of action of hydroxychloroquine is unknown. In additon to having anti-inflammatory properties, hydroxychloroquine has been shown to affect intracellular processing of surfactant protein.
No Intervention: control
control group which do not take hydroxychloroquine for treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Oxygenation status
Time Frame: at first month, at 3rd month, at 6th month, at 12th month
It is a repeated measurement variable. It is a binary variable (1/0). In a patient without supplemental O2, increase≥5% in O2 saturation or decrease in respiratory rate≥20% means significant change or responder to hydroxychloroquine and the varibale would be setted into "1". In a patient with supplemental O2, increase≥5% in O2 saturation or decrease in respiratory rate≥20% or withdrawal of O2 means significant change or responder to hydroxychloroquine and the varibale would be setted into "1". If no supplemental O2 is necessary, the O2 saturation and respiratory rate are measured in an awake patient after 5 min at rest. If the patient needs supplement O2 , the supplementation is withdrawn after 5 min at rest and the O2 saturation and respiratory rate are measured.
at first month, at 3rd month, at 6th month, at 12th month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Improvement in clinical manifestation
Time Frame: at first month, at 3rd month, at 6th month, at 12th month
It is a repeated measurement variable. It is a binary variable (1/0). If coughing resolved, intercostal retraction disappeared and weight for height back to normal is observed in a patient or improvement in chest radiography and pulmonary function tests is present, it means improvement in clinical manifestation and the variable would be setted into "1".
at first month, at 3rd month, at 6th month, at 12th month
