[A Case of Interstitial Pneumonitis Induced by TAS-102 for Liver and Lung Metastasis of Colorectal Cancer].

A 78-year-old man who developed metastatic liver and lung cancer after undergoing surgery for rectal and sigmoid colon cancer was treated with TAS-102 as fourth-line chemotherapy. He developed high fever and dyspnea and was referred to the emergency room 16 days after receiving the first course of TAS-102. Chest X-ray and computed tomography examinations showed bacterial pneumonia. He was treated with tazobactam/piperacillin, but developed severe dyspnea 4 days later. A diffuse ground-glass appearance was observed in both the lungs on chest X-ray examination, and drug-induced interstitial pneumonitis was suspected. Oxygenation and respiratory support were immediately administered, and steroid pulse therapy with methylprednisolone at 1,000mg/day was initiated. His symptoms and radiographic findings dramatically improved. The TAS102-J003 trial, a double-blind phase 2 trial, showed that interstitial pneumonitis occurs at a rate of only 0.9%, but can lead to severe complications, as observed in the present case. The possibility of interstitial pneumonitis should always be considered when a patient develops a fever and respiratory disorder during treatment containing TAS-102.

Prognosis and treatment of FOLFOX therapy related interstitial pneumonia: a plea for multimodal immune modulating therapy in the respiratory insufficient patient.

BACKGROUND: The FOLFOX regimen, i.e., folinic acid (FOL), fluorouracil (F) and oxaliplatin (OX), is a drug cocktail that is used to treat gastric and colorectal cancers. Despite the concomitant improvements in response rate, duration of response and patient survival, reports of serious toxic pulmonary side effects have progressively emerged. CASE PRESENTATION: We describe a patient who was treated with FOLFOX as an adjuvant to a rectosigmoidal resection of a rectosigmoidal carcinoma and who developed respiratory insufficiency requiring mechanical ventilation. Computed tomography (CT) imaging and open lung biopsy findings were compatible with interstitial pneumonia (IP). She received multimodal combination treatment (acetylcysteine, corticosteroids, immune globulins and cyclophosphamide) and survived. We performed a systematic literature search and reviewed all 45 reported cases of FOLFOX-related lung toxicity and/or pulmonary fibrosis for their clinical characteristics and their outcomes related to therapy. CONCLUSIONS: We found that for the 45 cases with available data, the median age was 70 years, and the male-female ratio was 3.5: 1. In the patients exhibiting only mild respiratory symptoms, discontinuation of the culprit drug (oxaliplatin) resulted in a 100% regression of the symptoms. However the prognosis of the respiratory insufficient patient proved to be grim: death occurred in 76.9% of the cases despite conventional treatment with corticosteroids. We therefore urge oncologists and critical care specialists not to limit their interventions to the discontinuation of chemotherapy, artificial ventilation, corticosteroids and glutathione replenishment and to consider the gradual introduction of additional immune-modulating agents whenever life-threatening respiratory symptoms in oxaliplatin-treated patients do not subside; all the more so considering the fact that our analysis showed that every patient who survived intubation and mechanical ventilation experienced a full clinical recovery.

Drug-induced interstitial pneumonitis in essential thrombocythemia treated with anagrelide.

Anagrelide, a phospholipase A2 inhibitor, is widely used in the management of essential thrombocythemia. To date, anagrelide has only rarely been reported to be associated with the development of drug-induced interstitial pneumonitis. We herein report two cases of anagrelide-associated interstitial pneumonitis. The patients were a 67-year-old woman and a 75-year-old man, both with essential thrombocythemia. Both cases developed interstitial pneumonitis at 8 weeks after administration of anagrelide. Because anagrelide-induced interstitial pneumonitis was suspected from CT scan and bronchoalveolar lavage fluid findings, anagrelide-therapy was discontinued and corticosteroid administration was initiated. Anagrelide withdrawal and corticosteroid administration resulted in marked symptom amelioration. A lymphocyte stimulation test using anagrelide was positive in both cases. As interstitial pneumonitis is a rare adverse event during anagrelide-therapy administration, physicians must be vigilant in identifying drug-induced interstitial pneumonitis in patients treated with anagrelide because early detection can decrease the severity and prevent mortality.

Successful treatment of gemcitabine-induced acute interstitial pneumonia with imatinib mesylate: a case report.

BACKGROUND: Gemcitabine is currently the standard chemotherapy for the adjuvant treatment of pancreatic cancer. This chemotherapeutic agent is generally well-tolerated, myelosuppression and gastrointestinal toxicity being common side effects. Nevertheless, gemcitabine-induced pulmonary toxicity has been rarely reported. Despite its low incidence, the spectrum of pulmonary injury is wide, including potentially fatal conditions. We report a case of acute interstitial pneumonia related to gemcitabine, completely solved with Imatinib Mesylate (IM). CASE PRESENTATION: The patient was a 69-year-old man, who developed a hypoxemic respiratory distress during adjuvant treatment with gemcitabine for stage IIA pancreatic cancer. The nonspecific diffuse alveolar involvement found on computed tomography (CT), together with the negative tests for infectious aetiology and the continuing severe respiratory failure despite a long course of broad-spectrum therapy, suggested gemcitabine-induced acute pneumonia as the most likely diagnosis. Thus, after the failure of steroids and all other conventional therapies, the patient was treated with imatinib mesylate on the basis of its activity in the management of graft-versus-host-induced lung fibrosis. A follow-up CT scan of chest one month later showed complete resolution of pneumonia. CONCLUSION: Despite the low frequency of serious pulmonary toxicity, gemcitabine widespread use warns clinicians to consider this life-threatening toxicity. The favourable clinical outcome with IM treatment was remarkable, warranting additional study of IM in the treatment of lung fibrosis.

Panitumumab-induced interstitial lung disease in a case of metastatic colorectal cancer.

BACKGROUND: A Japanese postmarketing survey of panitumumab revealed that panitumumab-associated interstitial lung disease (ILD) occurred in approximately 1% (19/1767) of patients, causing death in 36.8% of these cases. CASE REPORT: We report the case of a 60-year-old Japanese man who developed ILD associated with panitumumab therapy (third-line therapy) for metastatic sigmoid colon cancer involving the liver, lymph nodes, and lungs. 2 months after the initiation of panitumumab therapy, he developed a progressive nonproductive cough, dyspnea, and a fever, and was diagnosed with ILD. Intravenous pulse methylprednisolone treatment led to quick recovery. The patient had some risk factors for ILD associated with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors. CONCLUSION: Further studies are required to elucidate the association between anti-EGFR antibodies and ILD.

Interstitial and Granulomatous Lung Disease in Inflammatory Bowel Disease Patients.

BACKGROUND: Interstitial lung [ILD] disease and granulomatous lung disease [GLD] are rare respiratory disorders that have been associated with inflammatory bowel disease [IBD]. Clinical presentation is polymorphic and aetiology is unclear. METHODS: This was an ECCO-CONFER project. Cases of concomitant ILD or GLD and IBD, or drug-induced ILD/GLD, were collected. The criteria for diagnosing ILD and GLD were based on definitions from the American Thoracic Society and the European Respiratory Society and on the discretion of reporting clinician. RESULTS: We identified 31 patients with ILD. The majority had ulcerative colitis [UC] [n = 22]. Drug-related ILD was found in 64% of these patients, 25 patients [80.6%] required hospitalisation, and one required non-invasive ventilation. The causative drug was stopped in all drug-related ILD, and 87% of patients received systemic steroids. At follow-up, 16% of patients had no respiratory symptoms, 16% had partial improvement, 55% had ongoing symptoms, and there were no data in 13%. One patient was referred for lung transplantation, and one death from lung fibrosis was reported. We also identified 22 GLD patients: most had Crohn's disease [CD] [n = 17]. Drug-related GLD was found in 36% of patients and 10 patients [45.4%] required hospitalisation. The causative drug was stopped in all drug-related GLD, and 81% of patients received systemic steroids. Remission of both conditions was achieved in almost all patients. CONCLUSIONS: ILD and GLD, although rare, can cause significant morbidity. In our series, over half of cases were drug-related and therefore focused pharmacovigilance is needed to identify and manage these cases.

Interstitial pneumonia arising in a patient treated with oxaliplatin, 5-fluorouracil, and, leucovorin (FOLFOX).

Information concerning the pulmonary toxicity of oxaliplatin with infusional 5-fluorouracil plus leucovorin (FOLFOX) is very limited. We herein report the case of a patient with FOLFOX-induced interstitial pneumonia. An 82-year-old man with unresectable colon cancer liver metastases was referred to our department for chemotherapy with the FOLFOX protocol. After the administration of ten cycles, he visited our outpatient clinic with a 2-week history of coughing and shortness of breath; he was afebrile. A chest radiograph showed reticular shadows with ground-glass opacities mainly involving the middle and lower zones of the right lung. Computed tomography depicted ground-glass opacities with superimposed reticulation in the right lung. A diagnosis of FOLFOX-induced interstitial pneumonia was made based on the clinical course and imaging findings. The symptoms disappeared within 3 days after the cessation of the FOLFOX regimen and the initiation of high-dose corticosteroid treatment. Two months after the initiation of the corticosteroid treatment, complete remission of the radiological abnormalities was confirmed; thereafter, interstitial pneumonia did not recur despite the reintroduction of 5-fluorouracil/leucovorin alone, suggesting that 5-fluorouracil/leucovorin alone was not responsible for the development of the interstitial pneumonia. Thus, oxaliplatin, alone or in combination with 5-fluorouracil/leucovorin, may have caused the interstitial pneumonia in this patient. Once interstitial pneumonia has occurred, cessation of the regimen is mandatory, and high-dose corticosteroid treatment is commonly given to rescue patients from this potentially lethal complication.

Interstitial pneumonitis in the transplant patient: consider sirolimus-associated pulmonary toxicity.

Interstitial pneumonia in a transplant patient can have a varied etiology. Sirolimus (Rapamycin; Rapamune) is a popularly used immunosuppressant in solid organ transplantation that has anecdotally been associated with pulmonary toxicity. Sirolimus-induced pulmonary toxicity consists of a range of syndromes that is characterized by the presence of organizing pneumonia, interstitial pneumonitis, pulmonary alveolar proteinosis, focal fibrosis, or by the presence of alveolar hemorrhage. Diagnosis can be challenging and is usually made by exclusion of other etiologies. In this report we present two cases of sirolimus-associated pulmonary toxicity with a review of the literature.

Osimertinib-induced severe interstitial lung disease: A case report.

Lung cancer is globally one of the leading causes of malignant tumor-related mortality and ranks as having the highest incidence found in men and second in women. Osimertinib is a drug used to target lung cancer but its toxicity is not fully understood. Here we present a case of lung adenocarcinoma in a 78-year-old man that was treated and responded favorably with Osimertinib after the failure of other therapies. Unfortunately, the patient developed severe interstitial lung disease during the treatment procedure.

[Case of acute respiratory failure caused by drug-induced lung injury by shiniseihaito].

We present a case of acute respiratory distress syndrome (ARDS) caused by allergic reactions to shiniseihaito. An 84-year-old woman showed acute interstitial pneumonia followed by ARDS after taking shiniseihaito for the treatment of rhinitis. The ARDS were markedly improved with corticosteroid therapy. This case was diagnosed as being induced by shiniseihaito because it was compatible with 4 of 5 of Camus's criteria. The stimulation index of the drug lymphocyte stimulation test with shiniseihaito increased after corticosteroid therapy had been tapered and suggested that the mechanism of acute interstitial pneumonia in this case was allergic reaction induced by shiniseihaito. This is the seventh reported case of drug induced lung injury by shiniseihaito. We recommend careful observation when this medicine is prescribed.

[Interstitial pneumonitis in a patient treated with amiodarone -- case report]. / Srodmiazszowe zapalenie pluc u chorego leczonego amiodaronem -- opis przypadku.

Amiodarone, antiarrhythmic drug of III class is used in patients with supraventricular and ventricular arrhythmias, often with coexisting congestive heart failure. Side effects of amiodarone treatment are observed in approximately 75% of patients. Most dangerous are the symptoms of amiodarone pulmonary toxicity occuring in 2-17% of patients. We present a patient with COPD, in whom interstitial pneumonitis with radiologic features of organizing pneumonia developed after one year of amiodaron treatment due to supraventricular and ventricular arrhythmias. The drug was stopped and steroids were introduced due to marked respiratory insufficiency. Regression of pulmonary symptoms and improvement of ventilatory parameters were observed after 3 months of treatment. Pathogenesis, diagnostic procedures and current methods of treatment of this jatrogenic disease are discussed.

Sirolimus-related pulmonary toxicity mimicking 'asthma like' symptoms.

Sirolimus is an immunosuppressant with expanding use in pediatric organ transplantation, dermatology and rheumatology. We report two cases of children who developed asthma like symptoms and were diagnosed with interstitial lung disease, which responded to discontinuation of sirolimus. Pediatricians should be aware about the pulmonary side effects of sirolimus.

Interstitial pneumonitis associated with sirolimus in liver transplantation: a case report.

Sirolimus is a powerful immunosuppressive drug initially used in kidney transplant patients but now increasingly employed in recipients of other types of solid organ transplants, such as liver, heart, lung, or pancreas. Sirolimus is indicated for rescue therapy and to reduce the toxic side effects of calcineurin inhibitors. However, its use has been associated with an uncommon but important pulmonary toxicity. Reports have described interstitial pneumonitis, bronchiolitis obliterans, organizing pneumonia, and alveolar proteinosis. We present the case of a liver transplant patient with interstitial pneumonitis associated with sirolimus.

Interstitial Pneumonia Associated with the Influenza Vaccine: A Report of Two Cases.

Although the influenza vaccine is relatively safe and effective, serious complications can develop in rare cases. We encountered two cases of interstitial pneumonia that developed after vaccination during the 2014-2015 influenza season. Overall, nine cases, including the two presented here, have been recorded in PubMed and the Cochrane library; eight patients were treated with corticosteroids, and all nine survived, suggesting a good prognosis. Interstitial pneumonia is rare; however, we found an increase in its incidence after 2009. Therefore, clinicians must be aware of the possibility of this complication and duly educate all patients in advance.
