Idiopathic pulmonary fibrosis (IPF) is a rare and severe disease with a median survival of ~3 years. Nintedanib (NTD) has been shown to be useful in controlling interstitial lung disease (ILD) in IPF. Here we describe the experience of NTD use in IPF in a real-life setting. Objective. Our objective was to examine the safety profile and efficacy of nintedanib even in subjects treated with anticoagulants. Clinical data of patients with IPF treated with NTD at our center were retrospectively evaluated at baseline and at 6 and 12 months after the introduction of NTD. The following parameters were recorded: IPF clinical features, NTD tolerability, and pulmonary function tests (PFT) (i.e., Forced Vital Capacity (FVC) and carbon monoxide diffusing capacity (DLCO)). In total, 56 IPF patients (34% female and 66% male, mean onset age: 71 ± 11 years, mean age at baseline: 74 ± 9 years) treated with NTD were identified. At enrollment, HRCT showed an UIP pattern in 45 (80%) and a NSIP in 11 (20%) patients. For FVC and FEV1 we found no significant change between baseline and 6 months, but for DLCO we observed a decrease (p = 0.012). We identified a significant variation between baseline and 12 months for FEV1 (p = 0.039) and for DLCO (p = 0.018). No significant variation was observed for FVC. In the cohort, 18 (32%) individuals suspended NTD and 10 (18%) reduced the dosage. Among individuals that suspended the dosage, 14 (78%) had gastrointestinal (GI) collateral effects (i.e., diarrhea being the most common complaint (67%), followed by nausea/vomiting (17%) and weight loss (6%). Bleeding episodes have also not been reported in patients taking anticoagulant therapy. (61%). One patient died within the first 6 months and two subjects died within the first 12 months. In a real-life clinical scenario, NTD may stabilize the FVC values in IPF patients. However, GI side effects are frequent and NTD dose adjustment may be necessary to retain the drug in IPF patients. This study confirms the safety of NTD, even in patients treated with anticoagulant drugs.

Background. Glucocorticoids (GCs) have been shown to reduce mortality and the need for invasive mechanical ventilation (IMV) in SARS-CoV-2-induced acute respiratory distress syndrome (ARDS). It has been suggested that serum cytokines levels are markers of disease severity in ARDS, although there is only limited evidence of a relationship between the longitudinal cytokine profile and clinical outcomes in patients with SARS-CoV-2-induced ARDS treated with GC. Methods. We conducted a single-center observational study to investigate serial plasma cytokine levels in 17 patients supported with non-invasive ventilation (NIV) in order to compare the response in five patients who progressed to IMV versus 12 patients who continued with NIV alone. All patients received methylprednisolone 80 mg/day continuous infusion until clinical improvement. Results. The study groups were comparable at baseline. All patients survived. Although IL-6 was higher in the NIV group at baseline, several cytokines were significantly higher in the IMV group on day 7 (IL-6, IL-8, IL-9, G-CSF, IP-10, MCP-1, MIP-1α) and 14 (IL-6, IL-8, IL-17, G-CSF, MIP-1α, RANTES). No significant differences were observed between groups on day 28. Conclusions. Patients in the IMV group had higher inflammation levels at intubation than the NIV group, which may indicate a higher resistance to glucocorticoids. Higher GC doses or a longer treatment duration in these patients might have allowed for a better control of inflammation and a better outcome. Further studies are required to define the prognostic value of cytokine patterns, in terms of both GC treatment tailoring and timely initiation of IMV.

OBJECTIVE: Diaphragm dysfunction is a complication of cardiac surgery with partial or absent spontaneous recovery in most cases. Surgical diaphragm plication represents the only option when symptoms persist. Because training improves functional nerve recovery after a nerve lesion, we hypothesized that early diaphragm muscle training may be beneficial. METHODS: A prospective, randomized at 2:1 ratio, controlled trial of diaphragm training using an adjustable pressure device (Threshold; Philips Respironics Inc, Murrysville, Pa) versus no training (sham device) was performed in patients with diaphragm paralysis after major cardiac surgery. This 1-year study recruited consecutive adult patients with sniff fluoroscopy-defined diaphragm paralysis after coronary bypass, valve replacement, or both. The outcome measures were diaphragm function recovery assessed by sniff fluoroscopy, maximum inspiratory and expiratory pressures, and lung function tests. RESULTS: A total of 69 patients were randomized. At 12 months, 52 patients completed the study assessments, 36 in the treatment group and 16 in the control group. Inspiratory muscle training produced a significant improvement of diaphragm mobility after 12 months (P < .001). Most patients in the training group (77.78%) experienced a partial improvement (41.67%) or achieved a complete improvement (36.11%) versus no improvement (87.5%) or partial recovery (12.5%) among controls. CONCLUSIONS: Inspiratory muscle training may improve inspiratory muscle strength and increases paralyzed diaphragm mobility.

Background Pompe disease is an autosomal recessive metabolic disorder caused by the deficiency of the lysosomal enzyme acid α-glucosidase. This deficiency leads to glycogen accumulation in the lysosomes of muscle tissue causing progressive muscular weakness particularly of the respiratory system. Enzyme replacement therapy (ERT) has demonstrated efficacy in slowing down disease progression in infants. Despite the large number of studies describing the effects of physical training in juvenile and adult late onset Pompe disease (LOPD). There are very few reports that analyze the benefits of respiratory muscle rehabilitation or training. Methods The effectiveness of respiratory muscle training was investigated using a specific appliance with adjustable resistance (Threshold). The primary endpoint was effect on respiratory muscular strength by measurements of MIP and MEP. Eight late-onset Pompe patients (aged 13 to 58 years; 4 female, 4 male) with respiratory muscle deficiency on functional respiratory tests were studied. All patients received ERT at the dosage of 20 mg/kg/every 2 weeks and underwent training with Threshold at specified pressures for 24 months. Results A significant increase in MIP was observed during the follow-up of 24 month: 39.6 cm H 2 O (+ 25.0%) at month 3; 39.5 cm H 2 O (+ 24.9%) at month 6; 39.1 cm H 2 O (+ 23.7%) at month 9; 37.3 cm H 2 O (+ 18.2%) at month 12; and 37.3 cm H 2 O (+ 17.8%) at month 24. Median MEP values also showed a significant increase during the first 9 months: 29.8 cm H 2 O, (+ 14.3%) at month 3; 31.0 cm H 2 O (+ 18.6) at month 6; and 29.5 cm H 2 O (+ 12.9) at month 9. MEP was then shown to be decreased at months 12 and 24; median MEP was 27.2 cm H 2 O (+ 4.3%) at 12 months and 26.6 cm H 2 O (+ 1.9%) at 24 months. The FVC remain stable throughout the study. Conclusion An increase in respiratory muscular strength was demonstrated with Threshold training when used in combination with ERT.

Background: Respiratory intermediate care units (RICUs) are specialized areas aimed at optimizing the cost-benefit ratio of care. No data exist about the impact of opening a RICU on hospital outcomes. Objectives: We wondered if opening a RICU may improve the outcomes of patients with acute respiratory failure (ARF), acute exacerbation of chronic obstructive pulmonary disease (AECOPD), or community-acquired pneumonia (CAP). Methods: We analyzed the discharge abstracts of 2,372 admissions to the RICU and internal medicine units (IMUs) for ARF, AECOPD, and CAP. The IMUs at the Hospital of Trieste comprise emergency and internal wards. In order to investigate the determinants of outcomes, a matched case-control study was performed using clinical records. Results: The in-hospital mortality rate was lower in the RICU vs. IMUs (5.4 vs. 19.1%, p = 0.0001). Statistical differences did not change when comparing the RICU with the emergency and internal wards. After adjusting for potential confounders, the risk of death for patients with CAP, AECOPD, or ARF was significantly higher in the IMUs than in the RICU (OR 6.90, 3.19, and 6.7, respectively, p < 0.04). Both the frequency of transfer to the ICU (6 vs. 12%, p = 0.0001, OR 0.38) and the hospital stay (9.3 vs. 12.1 days, p = 0.0001) were reduced in patients admitted to the RICU compared to those admitted to non-RICUs. Significant differences were found in care management concerning chest physiotherapy, mechanical ventilation, antibiotics, and corticosteroids. Conclusions: The opening of a RICU may be advantageous to reduce in-hospital mortality, the need for ICU admission, and the hospital stay of patients with AECOPD, CAP, and ARF. Better use of care resources contributed to better patient management in the RICU.

The global spread of multidrug-resistant strains of tuberculosis (TB) mycobacteria was one of the main reasons leading the World Health Organisation to launch the Stop TB program worldwide. In spite of a slow decline of TB incidence and mortality worldwide, multidrug-resistant TB (MDR-TB) has increased in several countries. MDR-TB is caused by organisms that are resistant to at least isoniazid and rifampicin. The most drug-resistant forms of TB are the extensively drug-resistant TB (XDR-TB) strains caused by organisms that are resistant also to fluoroquinolones and any of the second-line anti-TB injectable drugs. XDR-TB can take 2 years or more to treat with drugs that are less effective, more toxic, and more expensive. Mortality for XDR-TB is very high, and the risk of the transmission between persons of XDR-TB strains is a matter of concern for health systems. Major issues associated with enhanced XDR-TB are non-implementation of DOT (directly observed therapy) and DOT expansion strategies, the insufficient supply or the poor quality of the anti-tuberculosis drugs, and the inadequate intake of the anti-tuberculosis medicines. Nevertheless, prior treatment of MDR-TB with second-line drugs is the strongest associated factor increasing the risk for XDR tuberculosis more than fourfold. Specialized rapid, effective diagnostic methods, including drug-sensitivity testing, are essential for a precise diagnosis of XDR-TB, and subsequent proper treatment. The global rise and spread of XDR-TB have serious effects on TB-control programs, and urge effective health policy responses. National TB control programmes working with all health services can prevent XDR-TB by ensuring that all the physicians and professionals caring for people with TB adhere to the International Standards for TB Care. Specialized centres at regional and national levels should be dedicated to care for difficult-to-treat and untreatable patients with XDR-TB.
