A 63-year-old male who was diagnosed with adenocarcinoma of the right lower lobe presented with 1 week of fever, cough, and progressive dyspnea and admitted to the Intensive Care Unit (ICU). After intubation, physical examination revealed copious, light bloody sputum and diffuse crackles and rales on lung auscultation. The patient was diagnosed as Stage IV adenocarcinoma, septic shock (lung infection), and acute respiratory distress syndrome. His oxygenation failed to improve despite sedation, restrictive fluid therapy, and methylprednisolone, antimicrobials therapy, protective ventilation, plasma supplement, and anticoagulation. Respiratory secretions suctioned from her endotracheal tube averaged 1.0 L daily. On day 2 after admission, octreotide was infused to control sputum volume. The patient's respiratory secretions decreased significantly, and on day 8, the ventilator mode was changed to pressure support ventilation, and the patient was extubated and dismissed from ICU.

| Introduction|| |
The cornerstone of acute respiratory distress syndrome (ARDS) treatment is protective ventilation. Octreotide has been reported to treat ARDS in animal studies. In addition, octreotide had also reported to control bronchorrhea successfully in lung adenocarcinoma and bronchioloalveolar cell carcinoma patients. Here, we presented a case who was diagnosed as lung adenocarcinoma and manifested bronchorrhea and ARDS. We hypothesized that octreotide may decrease sputum and inhibit inflammation simultaneously.
| Case Report|| |
A 63-year-old man presented with 1 week of fever, cough, and progressive dyspnea. He was diagnosed with adenocarcinoma of the right lower lobe with negative epidermal growth factor receptor mutation and multiple metastases involving contralateral lung [Figure 1]. He presented to a cancer hospital. He developed dyspnea while waiting for chemotherapy. He admitted to the Intensive Care Unit (ICU) because of acute respiratory failure.

The patient presented in respiratory distress. His temperature was 37°C; pulse rate was 150 beats/min; blood pressure was 130/(80 mmHg with norepinephrine infusion at a rate of 0.15 μg/kg min); respiratory rate was 30 breaths/min; and arterial oxygen saturation was 80% on 6 L/min facial mask oxygen. The patient received intubation and mechanical ventilation (FIO2 of 90% and positive end-expiratory pressure [PEEP] of 10 cm H2O). After intubation, physical examination revealed copious, light bloody sputum and diffuse crackles and rales on lung auscultation. Electrocardiography showed multiple premature ventricular contractions. Arterial blood gas showed hypoxemia and hypercapnia (PaO2:72 mmHg; PaCO2:56 mmHg; and pH: 7.23). Laboratory testing revealed leukocytosis with 16.15 × 109 cells/L, FIB: 0.51 g/L (1.88–4.35), APTT: 23.5 s (20.9–34.6), and DD: 8.51 mg/L (0–0.55).
The initial chest X-ray revealed bilateral lung infiltrates [Figure 2]. Results of sputum microbiology tests were negative for bacteria.
The patient was diagnosed as Stage IV adenocarcinoma, septic shock (lung infection), ARDS, and disseminated intravascular coagulation.
The patient received sedation with midazolam, propofol and dexmedetomidine, restrictive fluid therapy, methylprednisolone (80 mg, q12 h), and antimicrobials with meropenem, linezolid, fluconazole, protective ventilation, plasma supplement, and anticoagulation with low-weight heparin. However, his oxygenation failed to improve despite these measures. Respiratory secretions suctioned from her endotracheal tube averaged 1.0 L daily.
On day 2 after admission, an octreotide infusion at 0.05 mg/h was initiated. Twenty-four hours later, the patient's respiratory secretions decreased from 1.0 L to 300 mL daily, with reductions in FIO2 from 0.9 to 0.7. On day 3, respiratory secretions decreased from 300 mL to 200 mL daily and FIO2 from 0.7 to 0.5. Octreotide was discontinued on day 4 after admission, respiratory secretions decreased from 200 mL to 100 mL daily and FIO2 from 0.5 to 0.4 with PEEP 10 cm H2O [Figure 3]. On day 6, methylprednisolone was reduced from 80 mg to 60 mg, q12 h. On day 8, the ventilator mode was changed to pressure support ventilation, and the patient was extubated and dismissed from ICU to ward to receive further anticancer treatment.

| Discussion|| |
The cornerstone of ARDS treatment is protective ventilation which consists of low tidal volume and plateau pressure <30 cm H2O. In addition, restrictive fluid therapy is useful in decreasing the duration of mechanical ventilation although it may not improve survival. Recently, prone positioning ventilation in patients with a PaO2/FIO2 ratio <150 mmHg was reported to be associated with a significant survival benefit and was recommended by the American Thoracic Society and other societies. Pharmacologic therapies such as glucocorticoid may have value in decrease mortality in early ARDS, whereas others such as β2 agonists, statins, and keratinocyte growth factor, which targeted pathophysiologic alterations in ARDS, were not beneficial and demonstrated possible harm.
Octreotide has been reported to treat bronchorrhea in lung adenocarcinoma patients successfully in several cases.,, In 2006, octreotide was first reported to treat bronchorrhea in a patient with adenocarcinoma of the lung. Bronchorrhea was termed as the production of sputum of >100 mL/day. In this patient, the sputum volume was >1 L/day. After infusion of octreotide at 0.3 mg/day for 2 days, the sputum volume decreased to 150 mL. In another patient with bronchioloalveolar cell carcinoma, watery sputum production was also decreased from 1 L/day to 150 mL daily after 2-day infusion of octreotide 0.425 mg/day and remained minimal after discontinuation of octreotide. Recently, Roeder reported that a lung adenocarcinoma patient presented to the ICU with respiratory secretions averaged 2.5 L/day. The patient received octreotide infusion with 0.6 mg/day, and respiratory secretions decreased from 2.5 L to 300 mL daily in 24 h. Reduction in bronchorrhea persisted after discontinuation of octreotide.
Octreotide has been reported to treat ARDS in animal studies., Liu reported that in rat model of ARDS induced by paraguat, three drugs including somatostatin, octreotide, and dexamethasone were infused separately. Compared with control group, infusion with somatostatin, octreotide, or dexamethasone was associated with mitigation of pulmonary inflammatory responses including the improvement in lung ventilation, increase in PaO2 level, and decrease in PaCO2 level, suggesting that somatostatin and octreotide may be used as adjuvant therapy in ARDS patients. Zhang reported that in rat model of acute lung injury (ALI) induced by cecal ligation puncture, administration of somatostatin was associated with improved PaO2 level compared with controls. In addition, results of JAK-STAT-signaling pathways microarray chip evaluation showed that, of the 128 cDNA clones on the chip, 57 known unique genes in ALI group were upregulated as compared with controls. Altogether, these results demonstrated that somatostatin and its analog octreotide were effective in reducing inflammation of ARDS and thus may be used as potential pharmaceutical therapy in ARDS patients.
In our case, the patient was a lung adenocarcinoma patient with ARDS. He presented with respiratory secretions averaged 1.0 L daily. On prior literature results, we decided to provide the patient with octreotide which may decrease sputum and inhibit inflammation simultaneously. Surprisingly, the sputum production decreases greatly from 1 L to 100 mL per day. Besides, the patient's oxygenation improved with the application of octreotide and glucocorticoid which reflected the alleviation of alveoli inflammatory. It is a pity that we could not ascertain the anti-inflammatory action which was due to combined octreotide and glucocorticoid or any single agent.
To the best of our knowledge, this is the first report of octreotide in the treatment of bronchorrhea and ARDS in lung adenocarcinoma patient. We found that octreotide is effective in the treatment of bronchorrhea in lung adenocarcinoma patient, and octreotide may have a role in the treatment of ARDS with or without glucocorticoid.
