A patient with pulmonary alveolar proteinosis underwent whole lung lavage of the right lung. Lavage of the left lung was not immediately possible because of severe hypoxemia. Three days later, after correction of hypoxemia, we re-attempted the left lung lavage. However, the patient had severe hypoxemia (SpO2 < 80%) within a few minutes of performing right one lung ventilation (OLV). On bronchoscopic examination, proper tube location was confirmed. Bronchodilator nebulization and steroid injection were attempted with no effect...

Pulmonary alveolar proteinosis is a broad group of rare diseases that are defined by the occupation of a lung's gas-exchange area by pulmonary surfactants that are not properly removed. The clinical and radiologic phenotypes among them are very similar. The age of manifestation plays a central role in the differential diagnosis of the almost 100 conditions and provides an efficient path to the correct diagnosis. The diagnostic approach is tailored to identify genetic or autoimmune causes, exposure to environmental agents, and associations with numerous other diseases...

Association of fibrosis with autoimmune pulmonary alveolar proteinosis (aPAP) is rare. However, prognoses of such cases are poor and the process of the formation of fibrosis is still unknown. In this study, we report a case of aPAP with progressive fibrosis occurring in a 46-year-old woman. She had undergone several repetitions of whole lung lavage (WLL) for 7 years and granulocyte-macrophage colony-stimulating factor (GM-CSF) inhalation for 3 months; however, the progression of fibrosis was not hindered...

Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by alveolar accumulation of surfactant material with resulting hypoxemia and reduced lung function. Whole lung lavage (WLL) to physically remove the proteinaceous material from the affected lung is the standard treatment. Since its original description in 1964, there have been increasing numbers of WLL procedures done worldwide and the technique has been variously refined and modified. When done in experienced centers, WLL provides long lasting benefit in the majority of patients...

Objective: To evaluate the safety of the procedures of whole lung lavage(WLL) for pulmonary alveolar proteinosis(PAP) in perioperative period. Methods: In this retrospective study, we collected clinical data from 78 WLL procedures of PAP patients from January 2006 to June 2016 in Guangzhou Institute of Respiratory Disease. The causes of perioperative complications were analyzed. Results: Eighteen (23.07%) of the 78 procedures developed complications, including pleural effusion(n=4), pneumonia(n=4), cardiac failure(n=2), cardiac arrhythmia (n=2), pneumothorax(n=2), atelectasis(n=1), lung edema(n=1), laryngeal edema(n=1), pleural effusion and pneumonia(n=1)...

A 39-year-old man consulted our hospital because of an abnormal shadow on a chest X-ray without any symptoms. A chest computed tomography revealed patchy peripheral ground-glass attenuation, in the subpleural area. Bronchoalveolar lavage fluid was clear and transbronchial lung biopsy findings were inconclutive. A video-assisted thoracic surgery-biopsy was performed. The specimens demonstrated accumulation of proteinaceous materials within alveolar spaces. The patient was given a diagnosis of pulmonary alveolar proteinosis...

BACKGROUND AND OBJECTIVE: Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by alveolar filling. YKL-40, a chitinase-like protein produced by macrophages and epithelial cells, is increased in patients with interstitial lung diseases. We aimed to evaluate the role of YKL-40 as a biomarker for PAP. METHODS: A total of 34 patients with autoimmune PAP and 50 healthy controls were studied. YKL-40 was measured by ELISA in serum and bronchoalveolar lavage fluid (BALF)...

Indium-tin oxide (ITO) is used to produce flat panel displays and several other technology products. Composed of 90% indium oxide (In2O3) and 10% tin oxide (SnO2) by weight, ITO is synthesized under conditions of high heat via a process known as sintering. Indium lung disease, a recently recognized occupational illness, is characterized by pulmonary alveolar proteinosis, fibrosis, and emphysema. Murine macrophage (RAW 264.7) and epidermal (JB6) cells stably transfected with AP-1 to study tumor promoting potential, were used to differentiate between the toxicological profiles of sintered ITO (SITO) and unsintered mixture (UITO)...

The role of autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF) in the development of secondary pulmonary alveolar proteinosis (PAP) in patients exposed to occupational and environmental dust remains unclear. Herein, we describe two cases of secondary PAP who had GM-CSF antibodies and absence of STAT5 phosphorylation index, suggestive of a potential relationship between the appearance of GM-CSF antibodies and environmental dust exposure. However, whether the presence of GM-CSF antibodies is a part of the pathological process or represents an epiphenomenon is currently unknown...

Pulmonary alveolar proteinosis is a rare lung disease in which lipoproteinaceous material accumulates within the alveoli, interfering with gas exchange. The disease is classified into congenital, secondary, and acquired. The congenital form includes inborn errors of surfactant metabolism, lysinuric protein intolerance and mutations in the components of granulocyte-macrophage colony-stimulating factor receptor. The main symptoms are non-specific. The radiologic appearance of pulmonary alveolar proteinosis is bilateral, symmetric and perihilar airspace consolidation...

Pulmonary alveolar proteinosis (PAP) is a rare lung disease where periodic acid Schiff (PAS)-positive eosinophilic material accumulates in the alveoli of the lungs. Here we describe two cases of young males who presented with dynpnoea and weight loss. The HRCT scan of the chest in both cases showed the typical "crazy-paving" pattern and lung biopsies confirmed the diagnosis of PAP. They showed remarkable symptomatic improvement with therapeutic whole lung lavage.

We tested the role of Stat5 in dendritic cell and alveolar macrophage (AM) homeostasis in the lung using CD11c-cre mediated deletion (Cre(+)5(f/f)). We show that Stat5 is required for CD103(+) dendritic cell and AM development. We found that fetal monocyte maturation into AMs was impaired in Cre(+)5(f/f) mice, and we also confirmed impaired AM development of progenitor cells using mixed chimera experiments. In the absence of Stat5 signaling in AMs, mice developed alveolar proteinosis with altered lipid homeostasis...

Maintenance of tissue-specific organ lipid compositions characterises mammalian lipid homeostasis. Lung and liver synthesise mixed phosphatidylcholine (PC) molecular species subsequently "tailored" for function. Lungs progressively enrich disaturated PC (DSPC) directed to lamellar body (LB) surfactant stores prior to secretion. Liver accumulates polyunsaturated PC directed to VLDL assembly and secretion, or triglyceride stores. In each tissue, selective PC species enrichment mechanisms lie at the heart of effective homeostasis...

The simultaneous presentation of two noninflammatory pulmonary diseases, pulmonary alveolar proteinosis and Kaposi's sarcoma (Ks), in an HIV-infected patient, is described. A 29-year-old black race patient was admitted to the hospital because of general malaise, weight loss, dyspnea, chest pain, and cough with hemoptoic expectoration. Chest X-rays revealed a patchy bilateral alveolar pattern with a tendency toward the formation of condensations. The serological test revealed HIV positivity (CD4 counts of 393 cells/mm(3))...

Autoimmune pulmonary alveolar proteinosis (aPAP) is a rare disease characterized by the excessive accumulation of surfactant proteins within the alveolar spaces and by higher titers of autoantibodies to granulocyte-macrophage colony-stimulating factor (GM-CSF) in the serum and bronchoalveolar lavage fluid. The antibodies inhibit the maturation and phagocytosis of alveolar macrophages. Although the standard therapy for aPAP has been whole-lung lavage (WLL), this procedure is invasive and needs to be repeated for several years...

Infection with multiple pathogens concurrently has become less common since the introduction of potent antiretroviral agent and effective prophylactic agents. We describe a patient with pulmonary alveolar proteinosis (PAP) admitted with pneumonia who was found to have AIDS and diagnosed with Pneumocystis jiroveci pneumonia, human herpesvirus type 1 (HHV-1), and a concomitant cytomegalovirus viremia. Polymerase chain reaction viral load was used for diagnosis of HHV-1 and follow-up. The patient was treated with trimethoprim-sulfamethoxazole and ganciclovir and had a resolution of pneumonia...

Pulmonary alveolar proteinosis is a rare illness characterized by alterations in the normal depuration of surfactants from the alveolar space in a process dependent of the granulocyte-monocyte colony stimulating factor (GM-CSF). The most of the patients develop antibodies that neutralize this factor, avoiding the normal homeostasis of surfactants. Therapeutic options include the total lung washes and administration of GM-CSF when the washes fail. Despite the contribution related with the knowledge about of the nature of the disease, the measurement of serum antibodies anti-GM-CSF is not a routine technique...
