Pulmonary Fibrosis Related to Amiodarone-Is It a Standard Pathophysiological Pattern? A Case-Based Literature Review. Diagnostics (Basel) 2022; 12:diagnostics12123217. [PMID: 36553223 PMCID: PMC9777900 DOI: 10.3390/diagnostics12123217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 12/12/2022] [Accepted: 12/16/2022] [Indexed: 12/23/2022] Open
Abstract
Amiodarone hydrochloride is an antiarrhythmic drug, with proven efficacy in prevention and treatment of numerous arrhythmias, atrial fibrillation especially, or ventricular arrhythmias, with a long half-life (55-60 days). The increased risk of developing amiodarone-induced pulmonary fibrosis is directly related to the dose and the duration of the intake. Amiodarone-induced pulmonary toxicity is conditioned by dose, patient's age, and pre-existent pulmonary pathologies. The pattern for drug-induced lung injury may vary in many forms, but the amiodarone can cause polymorphous injuries such as diffuse alveolar damage, chronical interstitial pneumonia, organizing pneumonia, pulmonary hemorrhage, lung nodules or pleural disease. The pathological mechanism of pulmonary injury induced by amiodarone consists of the accumulation of phospholipid complexes in histocytes and type II pneumocytes. Differential diagnosis of pulmonary fibrosis induced by amiodarone is made mainly with idiopathic pulmonary fibrosis, left ventricular failure or infectious disease. Before starting treatment with amiodarone, patients should be informed of potential adverse effects and any new respiratory symptoms should promptly be reported to their family physician or attending physician. The assessment carried out at the initiation of amiodarone treatment should include at least chest X-ray and respiratory function tests and extrapulmonary evaluation.

Drug-related pneumonitis with radiographic hypersensitivity pneumonitis pattern: Three case series. Respir Med Case Rep 2021; 34:101498. [PMID: 34471597 PMCID: PMC8390688 DOI: 10.1016/j.rmcr.2021.101498] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 08/12/2021] [Accepted: 08/16/2021] [Indexed: 12/17/2022] Open
Abstract
Novel therapies have recently emerged for various diseases, and the management of drug-related pneumonitis (DRP) has become increasingly important. In particular, the hypersensitivity pneumonitis (HP) pattern of DRP has been increasingly recognized due to development of new therapeutic strategies, such as immunotherapy. However, literature describing detailed clinical cases is still lacking. Herein, we report three cases of DRP with typical HP radiographic pattern. These patients were treated with different drugs, namely nano albumin-bound (nab)-paclitaxel, everolimus, or nivolumab, but had common clinical features, including a good prognosis.

Abstract
OBJECTIVE To identify the optimal ventilation pressure for ventilated postmortem CT assessment of the lungs in cadaveric dogs and compare the optimal ventilation pressures between dogs with and without focal lung lesions. SAMPLE 12 cadaveric dogs. PROCEDURES CT was performed with dogs positioned in sternal recumbency within 30 to 180 minutes after death. After orotracheal intubation, lungs were aerated to ventilation pressures of 0, 10, 15, 20, 25, 30, and 35 cm H2O. Lung attenuation measurements were made at 5 predetermined anatomical locations with use of a multi-image analysis graphic user interface tool. Lungs were considered hyperaerated (-1000 to -901 HU), normo-aerated (-900 to -501 HU), poorly aerated (-500 to -101 HU), and nonaerated (-100 to 100 HU) on the basis of lung attenuation values. Optimal ventilation pressure was defined as the pressure at which the percentage of normo-aerated lung was greatest. For analysis, dogs were assigned to one group when focal lung lesions were evident and to another group when lesions were not evident. RESULTS Median optimal ventilation pressure was significantly higher for those dogs with lung lesions (35 cm H2O), compared with those without (25 cm H2O). CONCLUSIONS AND CLINICAL RELEVANCE A ventilation pressure of 35 cm H2O may be considered for ventilated postmortem CT to determine the presence of focal lung lesions; however, further investigation is required.

Intravesically instilled gemcitabine-induced lung injury in a patient with invasive urothelial carcinoma: A case report. World J Clin Cases 2020; 8:4652-4659. [PMID: 33083430 PMCID: PMC7559683 DOI: 10.12998/wjcc.v8.i19.4652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 07/28/2020] [Accepted: 08/26/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Gemcitabine is a chemotherapy agent with relatively low toxicities, as a valid option for elderly patients with underlying diseases. Gemcitabine-induced pulmonary toxicities are rare and various, ranging from self-limited episodes of bronchospasm to fatal, progressive, severe, interstitial pneumonitis and respiratory failure. Intravesical gemcitabine instillations are commonly used to reduce recurrence or progression for non–muscle-invasive bladder cancer or urothelial cancer. Few severe toxicities have been reported for the intravesical instillation is assumed to be completely separated from the systemic circulation.
CASE SUMMARY A 67-year-old patient received 30 cycles of intravesical gemcitabine instillation after transurethral resection and developed a 1-wk fever, cough, hemoptysis, and dyspnea. After a thorough checkup, bilateral consolidation and infiltration of the lungs were documented and a percutaneous lung biopsy confirmed organizing pneumonia after treatment with broad-spectrum empirical antibiotics failed. Tapered corticosteroids were administered, and pulmonary toxicity gradually resolved.
CONCLUSION Gemcitabine-induced pulmonary toxicities present with various manifestations. In spite of the rare pulmonary involvement by the intravesical gemcitabine instillation, health care professionals who administer gemcitabine chemotherapy in this way should monitor for gemcitabine-induced pulmonary toxicities, particularly in patients with high-risk factors.

Abstract
Severe delayed drug hypersensitivity reactions comprise different clinical entities and can involve different immune-mediated mechanisms. Common examples are severe cutaneous adverse reactions and druginduced internal organ injuries. The incidence of such reactions is overall low but seems to be on the rise reaching numbers as high as 9 per million individuals-years in the case of SJS/TEN and DRESS. Such conditions carry an important associated morbidity, and mortality can attain 40% in SJS/TEN patients, making these hypersensitivity reactions important targets when implementing preventive measures. Several risk factors have been identified for reaction severity; some are transverse, such as older age and underlying chronic diseases. The recent advances in pharmacogenetics allowed the identification of specific populations with higher risk and permitted strategic avoidance of certain drugs being HLA-B*57:01 screening in patients initiating abacavir the best successful example. In this work, we reviewed the epidemiology of SCARs and liver/kidney/lung drug-induced immune-mediated reactions. We focus on particular aspects such as prevalence and incidence, drugs involved, mortality and risk factors.

Abstract
Eribulin is a chemotherapeutic agent used for advanced breast cancer, but there are some reports of eribulin-induced lung injuries. Three of our patients experienced eribulin-related lung injuries. Radiology revealed organizing pneumonia in two cases and diffuse ground-glass shadows indicative of hypersensitivity pneumonitis in the third. A retrospective survey of patients treated with eribulin at our hospital identified no other cases of eribulin-induced lung injuries. Overall, drug-related lung injuries occurred in 2.8% of our eribulin-treated patients, which is similar to the rates reported for other anticancer drugs. The findings from these three cases provide guidance for the safe use of eribulin.

Abstract
In 2016, there was an estimated 1.8 million new cases of cancer diagnosed in the United States. Remarkable advances have been made in cancer therapy and the 5-year survival has increased for most patients affected by malignancy. There are growing numbers of patients admitted to intensive care units (ICU) and up to 20% of all patients admitted to an ICU carry a diagnosis of malignancy. Respiratory failure remains the most common reason for ICU admission and remains the leading causes of death in oncology patients. There are many causes of respiratory failure in this population. Pneumonia is the most common cause of respiratory failure, yet there are many causes of respiratory insufficiency unique to the cancer patient. These causes are often a result of immunosuppression, chemotherapy, radiation treatment, or hematopoietic stem cell transplant (HCT). Treatment is focused on supportive care and specific therapy for the underlying cause of respiratory failure. Noninvasive modalities of respiratory support are available; however, careful patient selection is paramount as indiscriminate use of noninvasive positive pressure ventilation is associated with a higher mortality if mechanical ventilation is later required. Historically, respiratory failure in the cancer patient had a grim prognosis. Outcomes have improved over the past 20 years. Survivors are often left with significant disability.

Abstract
Drug-induced interstitial lung disease (DIILD) is a serious side effect of chemotherapy in cancer patients with an extremely high mortality rate. In this study, to identify genetic variants with greater risk of DIILD, we carried out whole genome sequencing (WGS) of germline DNA samples from 26 patients who developed DIILD, and conducted a case-control association study between these 26 cases and general Japanese population controls registered in the integrative Japanese Genome Variation Database (iJGVD) as a screening study. The associations of 42 single nucleotide variants (SNVs) showing P < 0.0001 were further validated using an independent cohort of 18 DIILD cases as a replication study. A further combined analysis of the screening and replication studies showed a possible association of two SNVs, rs35198919 in intron 1 of the chromosome 22 open reading frame 34 (C22orf34) and rs12625311 in intron 1 of the teashirt zinc finger homeobox 2 (TSHZ2), with DIILD (Pcombined = 1.87 × 10−5 and 5.16 × 10−5, respectively). Furthermore, in a subgroup analysis of epidermal growth factor receptor (EGFR)–tyrosine kinase inhibitor (TKI)-induced interstitial lung disease (ILD), we observed seven candidate SNVs that were possibly associated with ILD (P < 0.00001). This is the first study to identify genetic markers for the risk of DIILD using WGS. Collectively, our novel findings indicate that these SNVs may be applicable for predicting the risk of DIILD in patients receiving chemotherapy.

Drug-Induced Interstitial Lung Disease: A Systematic Review. J Clin Med 2018; 7:jcm7100356.

Abstract
Background: Drug-induced interstitial lung disease (DIILD) occurs as a result of numerous agents, but the risk often only becomes apparent after the marketing authorisation of such agents. Methods: In this PRISMA-compliant systematic review, we aimed to evaluate and synthesise the current literature on DIILD. Results: Following a quality assessment, 156 full-text papers describing more than 6000 DIILD cases were included in the review. However, the majority of the papers were of low or very low quality in relation to the review question (78%). Thus, it was not possible to perform a meta-analysis, and descriptive review was undertaken instead. DIILD incidence rates varied between 4.1 and 12.4 cases/million/year. DIILD accounted for 3–5% of prevalent ILD cases. Cancer drugs, followed by rheumatology drugs, amiodarone and antibiotics, were the most common causes of DIILD. The radiopathological phenotype of DIILD varied between and within agents, and no typical radiological pattern specific to DIILD was identified. Mortality rates of over 50% were reported in some studies. Severity at presentation was the most reliable predictor of mortality. Glucocorticoids (GCs) were commonly used to treat DIILD, but no prospective studies examined their effect on outcome. Conclusions: Overall high-quality evidence in DIILD is lacking, and the current review will inform larger prospective studies to investigate the diagnosis and management of DIILD.

Correlation between clinical features, high-resolution computed tomography findings, and a visual scoring system in patients with pneumonia due to Mycoplasma pneumoniae. Respir Investig 2018; 56:320-325. [PMID: 29764747 DOI: 10.1016/j.resinv.2018.03.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2017] [Revised: 03/01/2018] [Accepted: 03/07/2018] [Indexed: 01/12/2023]
Abstract
BACKGROUND Mycoplasma pneumoniae (MP) is the primary cause of community-acquired pneumonia. We aimed to evaluate the correlation between clinical features, with special reference to hypoxemia and the total affected area obtained using high-resolution computed tomography (HRCT). METHODS Medical records of MP pneumonia patients > 15 years of age at Kyorin University Hospital between January 2006 and November 2013 were reviewed retrospectively and compared to patients with Streptococcus pneumoniae pneumonia, diagnosed between January 2013 and September 2014. RESULTS We identified 65 and 32 patients with MP- and S. pneumoniae pneumonia, respectively. HRCT data were available for 42 and 32 patients with MP- and S. pneumoniae pneumonia, respectively. Data were available for all hypoxemic patients. Hypoxemia was significantly higher in patients with S. pneumoniae (14/32, p = 0.008) than those with MP (5/39). Total visual score on HRCT correlated significantly with hypoxemia in both groups, but showed significantly higher scores with MP- than with S pneumoniae pneumonia in hypoxemic patients. MP pneumonia showed significant positive correlation between the total visual score and serum inflammatory markers (C-reaction protein [r = 0.43, p = 0.025] and lactate dehydrogenase [r = 0.466, p = 0.016]). In both groups, individual scores in the middle and lower lung fields were significantly higher than in the upper field, suggesting zonal predominance. CONCLUSIONS This study provides the first evidence that the total affected area on lung HRCT was more with MP compared to S. pneumoniae pneumonia in hypoxemic patients and positively correlated with hypoxemia and serum inflammatory markers.

European LeukemiaNet recommendations for the management and avoidance of adverse events of treatment in chronic myeloid leukaemia. Leukemia 2016; 30:1648-71.

Abstract
Most reports on chronic myeloid leukaemia (CML) treatment with tyrosine kinase inhibitors (TKIs) focus on efficacy, particularly on molecular response and outcome. In contrast, adverse events (AEs) are often reported as infrequent, minor, tolerable and manageable, but they are increasingly important as therapy is potentially lifelong and multiple TKIs are available. For this reason, the European LeukemiaNet panel for CML management recommendations presents an exhaustive and critical summary of AEs emerging during CML treatment, to assist their understanding, management and prevention. There are five major conclusions. First, the main purpose of CML treatment is the antileukemic effect. Suboptimal management of AEs must not compromise this first objective. Second, most patients will have AEs, usually early, mostly mild to moderate, and which will resolve spontaneously or are easily controlled by simple means. Third, reduction or interruption of treatment must only be done if optimal management of the AE cannot be accomplished in other ways, and frequent monitoring is needed to detect resolution of the AE as early as possible. Fourth, attention must be given to comorbidities and drug interactions, and to new events unrelated to TKIs that are inevitable during such a prolonged treatment. Fifth, some TKI-related AEs have emerged which were not predicted or detected in earlier studies, maybe because of suboptimal attention to or absence from the preclinical data. Overall, imatinib has demonstrated a good long-term safety profile, though recent findings suggest underestimation of symptom severity by physicians. Second and third generation TKIs have shown higher response rates, but have been associated with unexpected problems, some of which could be irreversible. We hope these recommendations will help to minimise adverse events, and we believe that an optimal management of them will be rewarded by better TKI compliance and thus better CML outcomes, together with better quality of life.

Abstract
Background Triple-negative breast cancers (TNBCs) lack the estrogen, progesterone, and epidermal growth factor (EGF) receptor-2 (HER2/neu) receptors. Patients with TNBC have typical high grading, more frequent relapses, and exhibit poorer outcomes or prognosis compared with the other subtypes of breast cancers. Currently, there are no targeted therapies that are effective for TNBC. Preclinical antitumor activity of oseltamivir phosphate (OP) therapy was investigated to identify its role in tumor neovascularization, growth, invasiveness, and long-term survival in a mouse model of human TNBC. Methods Live cell sialidase, water soluble tetrazolium, WST-1 cell viability, and immunohistochemistry assays were used to evaluate sialidase activity, cell survival, and the expression levels of tumor E-cadherin, N-cadherin, and host endothelial CD31+/PECAM-1 cells in archived paraffin-embedded TNBC MDA-MB-231 tumors grown in RAGxCγ double mutant mice. Results OP, anti-Neu1 antibodies, and matrix metalloproteinase-9-specific inhibitor blocked Neu1 activity associated with EGF-stimulated TNBC MDA-MB-231 cells. OP treatment of MDA-MB-231 and MCF-7 cells and their long-term tamoxifen-resistant clones reproducibly and dose-dependently reduced the sialidase activity associated with EGF-stimulated live cells and the cell viability after 72 hours of incubation. Combination of 1 μM cisplatin, 5-FU, paclitaxel, gemcitabine, or tamoxifen with OP dosages ≥300 μg/mL significantly reduced cell viability at 24, 48, and 72 hours when compared to the chemodrug alone. Heterotopic xenografts of MDA-MB-231 tumors developed robust and bloody tumor vascularization in RAG2xCγ double mutant mice. OP treatment at 30 mg/kg daily intraperitoneally reduced tumor vascularization and growth rate as well as significantly reduced tumor weight and spread to the lungs compared with the untreated cohorts. OP treatment at 50 mg/kg completely ablated tumor vascularization, tumor growth and spread to the lungs, with significant long-term survival at day 180 postimplantation, tumor shrinking, and no relapses after 56 days off-drug. OP 30 mg/kg cohort tumors expressed significantly reduced levels of human N-cadherins and host CD31+ endothelial cells with concomitant significant expression of E-cadherins compared to the untreated cohorts. Conclusion OP monotherapy may be the effective treatment therapy for TNBC.

Abstract
BACKGROUND Snail, a transcriptional factor and repressor of E-cadherin is well known for its role in cellular invasion. It can regulate epithelial to mesenchymal transition (EMT) during embryonic development and in epithelial cells. Snail also mediates tumor progression and metastases. Silencing of Snail and its associate member Slug in human A2780 ovarian epithelial carcinoma cell line was investigated to identify its role in tumor neovascularization. METHODS Live cell sialidase, WST-1 cell viability and immunohistochemistry assays were used to evaluate sialidase activity, cell survival and the expression levels of tumor E-cadherin, N-cadherin, VE-cadherin, and host endothelial CD31+(PECAM-1) cells in archived paraffin-embedded ovarian A2780, A2780 Snail shRNA GIPZ lentiviral knockdown (KD) and A2780 Slug shRNA GIPZ lentiviral KD tumors grown in RAGxCγ double mutant mice. RESULTS Oseltamivir phosphate (OP), anti-Neu1 antibodies and MMP-9 specific inhibitor blocked Neu1 activity associated with epidermal growth factor (EGF) stimulated A2780 ovarian epithelial carcinoma cells. Silencing Snail in A2780 cells abrogated the Neu1 activity following EGF stimulation of the cells compared to A2780 and A2780 Slug KD cells. OP treatment of A2780 and cisplatin-resistant A2780cis cells reproducibly and dose-dependently abated the cell viability with a LD50 of 7 and 4 μm, respectively, after 48 h of incubation. Heterotopic xenografts of A2780 and A2780 Slug KD tumors developed robust and bloody tumor vascularization in RAG2xCγ double mutant mice. OP treatment at 50 mg/kg daily intraperitoneally did not significantly impede A2780 tumor growth rate but did cause a significant reduction of lung metastases compared with the untreated and OP 30mg/kg cohorts. Silencing Snail in A2780 tumor cells completely abrogated tumor vascularization, tumor growth and spread to the lungs in RAGxCγ double mutant mice. A2780 and A2780 Slug KD tumors expressed high levels of human N- and VE-cadherins, and host CD31+ endothelial cells, while A2780 Snail KD tumors expressed E-cadherin and reduced host CD31+ cells. OP 50mg/kg cohort tumors had reduced numbers of host CD31+ cells compared to a higher expression levels of CD31+ cells in tumors from the untreated control and OP 30mg/kg cohorts. CONCLUSION Snail transcriptional factor is an important intermediate player in human ovarian tumor neovascularization.

Abstract
Treatment of inoperable, locally advanced non-small cell lung cancer (LA-NSCLC) is challenging and requires a multidisciplinary approach considering both local therapy and systemic therapy. Based on the results from several phase III studies and 2 meta-analyses, the use of concomitant chemoradiation therapy (ChRT) could significantly improve overall survival and is considered the standard of care in LA-NSCLC with good performance status. Currently, no evidence has shown a significant survival benefit of third-generation regimens applied in combination with ChRT compared with second-generation regimens. For regimens concomitant with radiation therapy, full-dose chemotherapy (such as cisplatin and etoposide or cisplatin and vinblastine) might be preferred. Additional full-dose consolidation paclitaxel-carboplatin is recommended when patients receive weekly paclitaxel-carboplatin ChRT. Effective novel chemotherapy agents or targeted therapies are required to further improve the outcome of patients with LA-NSCLC. In addition, personalized medicine concomitant with radiation therapy is a promising approach. However, little evidence exists concerning the effectiveness of this novel approach.

Abstract
Pulmonary complications of antineoplastic therapy are common and are an important cause of respiratory morbidity. The pulmonary toxicity should be taken into account in every patient with respiratory problems who is or has been treated with antineoplastic agents. The diagnosis of drug-induced pulmonary toxicity is complex and should be based on the medical history, clinical, radiological and pathological findings. None of them are specific but they can guide the diagnostic process. The treatment of pulmonary abnormalities caused by chemotherapy is mostly supportive and based on cessation of the causative agent. However, the therapeutic options in oncology setting are usually limited thus the decision about changing the treatment should be taken with caution.
