We present five cases of cytomegalovirus (CMV) pneumonitis occurring in patients after recent T cell deplete allogeneic stem cell transplantation (AlloHSCT). These cases were complicated by an organising pneumonia (during the recovery period) with a predominantly central peribronchial pattern. All patients presented with evidence of active CMV pneumonitis which was treated successfully with anti-viral therapy but was followed by persistent severe dyspnoea, cough and hypoxia. High resolution computed tomography (HRCT) imaging showed widespread central peribronchial consolidation with traction bronchiectasis...

We report a case with suggestive antiprogrammed death-1 inhibitor-related pneumonitis in an endometrial cancer patient. This case presented with fever and cough after three dosages of nivolumab. Computed tomography initially showed centrilobular nodularities in a unilateral lung, which was compatible with aspiration pneumonia. However, diffuse ground-glass opacities (GGO) rapidly developed in the unilateral lung over 4 days despite the use of broad-spectrum antibiotics. Development of GGO was considered to be related to a nivolumab-mediated immune reaction...

The morbidity and mortality of community-acquired pneumonia (CAP) are still elevated and two aspects seem to contribute to a worse outcome: an uncontrolled inflammatory reaction and an inadequate immune response. Adjuvants, including corticosteroids and intravenous immunoglobulins, have been proposed to counterbalance these effects but their efficacy is only partial. We examined the immunomodulatory activity of Pidotimod (PDT), a synthetic dipeptide molecule in adult patients hospitalized for CAP. Sixteen patients with a diagnosis of CAP and a PSI score III or IV and/or a CURB-65 0-2 were randomized to receive either levofloxacin 500 mg b...

RATIONALE: Unlike many other COPD studies, the 4-year UPLIFT trial permitted inhaled corticosteroid (ICS) use during run-in and treatment phases. This provided the opportunity to prospectively observe the continuing effects of ICS on respiratory events in closely observed COPD population. OBJECTIVES: We aimed to determine rate and number of episodes of pneumonia and exacerbations of COPD in patients entering the study on no ICS, fluticasone proprionate (FP), and other ICS...

A large number of studies, evaluated by several meta-analyses, indicate that patients with chronic obstructive pulmonary disease (COPD) treated with inhaled corticosteroids have a significantly increased risk of pneumonia which, however, is not associated with a corresponding increase in mortality. The increased risk seems to be exclusive of COPD, since meta-analyses involving patients with asthma treated with inhaled corticosteroids did not show a risk of pneumonia higher than that of the general population...

Acute respiratory distress syndrome (ARDS) is caused by infectious insults, such as pneumonia from various pathogens or related to other noninfectious events. Clinical and histopathologic characteristics are similar across severely affected patients, suggesting that a common mode of immune reaction may be involved in the immunopathogenesis of ARDS. There may be etiologic substances that have an affinity for respiratory cells and induce lung cell injury in cases of ARDS. These substances originate not only from pathogens, but also from injured host cells...

BACKGROUND: Three classes of inhaler medications are used to manage chronic obstructive pulmonary disease (COPD): long-acting beta-agonists (LABA), long-acting muscarinic antagonists (LAMA), and inhaled corticosteroids (ICS). When two classes of medications are required, LAMA plus LABA (LAMA+LABA) and LABA plus ICS (LABA+ICS) are often selected because these combinations can be administered via a single medication device. The previous Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidance recommended LABA+ICS as the first-line treatment for managing stable COPD in high-risk people of categories C and D...

BACKGROUND: The FLAME study demonstrated that indacaterol/glycopyrronium (IND/GLY), the fixed-dose combination of a long-acting β2-agonist (LABA, IND) and a long-acting muscarinic antagonist (LAMA, GLY), was superior to salmeterol/fluticasone combination (SFC) in preventing exacerbations in COPD patients with a high risk of exacerbations. In this study, we report a prespecified analysis of the efficacy and safety of IND/GLY versus SFC in Asian patients from the FLAME study. PATIENTS AND METHODS: Patients from Asian centers with moderate-to-very severe COPD and ≥1 exacerbation in the previous year from the 52-week, randomized FLAME study were included...

BACKGROUND: Community-acquired pneumonia (CAP) is more common in patients with COPD than in the adult general population, with studies of hospitalized CAP patients consistently reporting COPD as a frequent comorbidity. However, despite an increasing recognition of its importance, large studies evaluating the incidence patterns over time, risk factors and burden of CAP in COPD are currently lacking. METHODS: A retrospective observational study using a large UK-based database of linked primary and secondary care records was conducted...

A 40-year-old cystic fibrosis woman with a history of double-lung transplantation 2 years previously was admitted for a progressive respiratory distress. Physical examination revealed fever (39°C) and diffuse bilateral lung crackles. Laboratory findings included severe hypoxemia and inflammatory syndrome. Bronchoalveolar lavage and serological test were positive for mycoplasma pneumonia. As the patient did not improve after 3 days of antibiotics and donor-specific HLA antibodies had been detected, an acute antibody-mediated graft rejection was treated with high-dose corticosteroids, plasma exchange, intravenous immunoglobulin, and rituximab...
