Effectiveness of Combined Therapy with Pirfenidone and Erythromycin for Unclassifiable Interstitial Pneumonia Induced by HTLV-1-associated Bronchioloalveolar Disorder (HABA)

چکیده
Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus involved in the pathogenesis of adult T-cell leukemia (ATL) and HTVL-1-associated bronchioloalveolar disorder (HABA). The clinical and pathological findings of HABA have been characterized as either a diffuse panbronchiolitis (DPB) pattern or idiopathic interstitial pneumonia (IIP) pattern. Treatments for HABA include corticosteroids for the IIP pattern and erythromycin for the DPB pattern. We herein report a case of HABA-associated unclassifiable interstitial pneumonia that improved with combined therapy with pirfenidone and erythromycin. This is the first report on the effectiveness of combined therapy with pirfenidone and erythromycin for HABA.

Since the seminal report by Averill A. Liebow in 1968 [1] of the first classification of idiopathic interstitial pneumonias (IIPs), consisting of five entities including ‘‘usual or classical interstitial pneumonia’’ (UIP), a secure diagnosis has, until recently, required histopathological evaluation. A histologically based classification might appear paradoxical, as a biopsy is performed in onl...

Human T-cell lymphotropic virus type-1 (HTLV-1)-associated bronchioloalveolar disorder (HABA) is a specific state with chronic and progressive respiratory symptoms caused by bronchiolar or alveolar disorder characterized by smoldering adult T-cell leukemia or the HTLV-I carrier state. We herein report a rare case of HABA with an initial presentation of mosaic perfusion in the lung. The diagnosi...

Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disorder characterized by oculocutaneous albinism, bleeding tendency, and lysosomal accumulation of ceroid-like material, with occasional development of interstitial pneumonia (IP). Nine genetically distinct subtypes of HPS are known in humans; IP develops primarily in types 1 and 4. Most reported cases of HPS with IP are type 1, and the...

Systemic sclerosis (SSc)-associated interstitial lung disease (SSc-ILD) has become the leading SSc-related cause of death. Although various types of immunosuppressive therapy have been attempted for patients with SSc-ILD, no curative or effective treatment strategies for SSc-ILD have been developed. Therefore, management of patients with SSc-ILD remains a challenge. Here, we report a Chinese, f...
