Brain abscesses caused by Cladophialophora bantiana in a lung transplant patient: A case report and review of the literature.

Cladophialophora bantiana brain abscesses are rare, but are frequently and quickly lethal in transplanted patients. We report the case of a 63-year-old man who had undergone lung transplantation for chronic obstructive pulmonary disease and presented with headaches and a neurological deficit. Magnetic resonance imaging revealed multiple brain abscesses. C. bantiana was identified by DNA sequencing performed directly on cerebral tissue obtained by surgical biopsy. After 6 months of antifungal treatment, the brain abscesses were replaced by ischemic sequelae. The patient died suddenly 2 months later from a pulmonary bacterial infection. This is the second reported case of C. bantiana brain abscesses in a lung transplant recipient, to our knowledge, who experienced a long survival period with medical antifungal treatment alone. We review the literature and discuss our treatment.

Mid-term pulmonary sequelae after hospitalisation for COVID-19: The French SISCOVID cohort.

BACKGROUND: Even though COVID-19 clinical features, pathogenesis, complications, and therapeutic options have been largely described in the literature, long-term consequences in patients remain poorly known. METHODS: The French, multicentre, non-interventional SISCOVID study evaluated lung impairment three (M3) and six months (M6) after hospital discharge in patients recovered from COVID-19. Evaluation was based on clinical examination, pulmonary function tests, and chest computed tomography (CT-scan). RESULTS: Of the 320 included patients (mean age: 61 years; men: 64.1%), 205 had had a severe form of COVID-19, being hospitalised in an intensive care unit (ICU), and requiring high flow nasal cannula, non-invasive ventilation, or invasive mechanical ventilation. At M6, 54.1% of included patients had persistent dyspnoea (mMRC score ≥1), 20.1% severe impairment in gas diffusing capacity (DLCO <60% pred.), 21.6% restrictive ventilatory pattern (total lung capacity <80% pred.), and 40% a fibrotic-like pattern at CT-scan. Fibrotic-like pattern and restrictive ventilatory pattern were significantly more frequent in patients recovered from severe than non-severe COVID-19. Improved functional and radiological outcomes were observed between M3 and M6. At M6, age was an independent risk factor for severe DLco impairment and fibrotic-like pattern and severe COVID-19 form was independent risk factor for restrictive ventilatory profile and fibrotic-like pattern. CONCLUSION: Six months after discharge, patients hospitalised for COVID-19, especially those recovered from a severe form of COVID-19, frequently presented persistent dyspnoea, lung function impairment, and persistent fibrotic-like pattern, confirming the need for long-term post-discharge follow-up in these patients and for further studies to better understand long-term COVID-19 lung impairment.

Hemodynamic profile of pulmonary hypertension (PH) in ARDS.

Acute respiratory distress syndrome (ARDS) is a diffuse lung injury that leads to a severe acute respiratory failure. Traditional diagnostic criteria for pulmonary hypertension (PH), in this situation, may be unreliable due to the effects of positive pressure ventilation and vasoactive agents. The aim of this study is to describe the hemodynamic characteristics of PH secondary to ARDS, in relation with respiratory parameters. We assessed the hemodynamic, respiratory function, and ventilator parameters in a cohort of 38 individuals with ARDS-associated PH defined by mean pulmonary arterial pressure (mPAP) ≥ 25 mmHg. Individual characteristics: PaO2/FiO2 = 110 ± 60 mmHg, alveolar-arterial oxygen gradient (A-aO2) = 549 ± 148.9 mmHg, positive end-expiratory pressure (PEEP) = 8.7 ± 3.5 cmH2O, pulmonary static compliance (Cstat) = 30 ± 12.1 L*cmH2O-1, mPAP = 35.4 ±6.6 mmHg, pulmonary artery wedge pressure (PAWP) = 15.6 ± 5.5 mmHg, cardiac index (CI) = 3.4 ± 1.2 L/min/m2, pulmonary vascular resistance (PVR) = 3.3 ± 1.6 Wood units (WU), right atrial pressure (RAP) = 13.4 ± 5.4 mmHg, diastolic pulmonary gradient (DPG) = 12.6 ± 6.5 mmHg, and trans-pulmonary gradient (TPG) = 19.7 ± 7.7 mmHg. The composite marker-DPG >7 mmHg and PVR > 3 WU-is associated with lower CI ( P = 0.016), higher mPAP ( P = 0.003), and lower pulmonary static compliance ( P = 0.028). We confirmed a poor prognosis of ARDS associated with PH, with a 50% survival rate after 17 days. We observed that the survival rate at 28 days was better in the case of improvement in the PaO2/FiO2 ratio in the first 24 h (log rank P = 0.003). ARDS associated with PH is a severe condition with a very poor survival rate. The composite marker DPG > 7 mmHg and PVR > 3 WU seemed to better describe the hemodynamic and respiratory dysfunction. The improvement in PaO2/FiO2 ratio in the first 24 h defined a better survival in our cohort of patients.

Successful treatment with ceritinib after crizotinib induced hepatitis.

We report two cases of acute hepatitis induced by crizotinib in patients with ALK-rearranged non-small cell lung cancer (NSCLC) who were treated after by a second generation of ALK inhibitor without any incident. These cases suggest that ceritinib could be used as an alternative agent when crizotinib is responsible for hepatitis.

Gastrointestinal perforations in patients treated with erlotinib: A report of two cases with fatal outcome and literature review.

Erlotinib has been approved as second-line treatment in patients with non-small cell lung cancer (NSCLC) experiencing relapse after first-line platinum-based chemotherapy. Herein, we report two occurrences of erlotinib-associated gastrointestinal perforation (GIP) in NSCLC patients. Two patients aged 60 and 79 years received erlotinib as third- and second-line NSCLC treatment, respectively. GIP occurred following 3 weeks and 6 months of erlotinib treatment, leading to death a few days later in both patients, neither of whom had any intestinal metastasis. Risk factors related to erlotinib-induced GIP were concomitant oral corticosteroid therapy and ciprofloxacin administration, which may result in erlotinib overexposure. GIP is a severe adverse drug reaction of erlotinib, infrequently described in the literature, compared to other targeted therapies. The lethal risk of erlotinib-associated GIP should be taken into account when evaluating the benefit-risk balance of erlotinib in patients without epidermal growth factor receptor activating mutations.
