Anti-synthetase positive cases were not rare among IIPs. Anti-synthetase should be screened for in IIPs, especially in pathological NSIP or UIP with lymphoid follicles. These patients should be screened for anti-synthetase even if no suggestive extrapulmonary manifestation exists.

Anti-CADM-140-positive DM-ILD was characterized by lower consolidation or GGA pattern, random GGA pattern, and the absence of intralobular reticular opacities.

Repeated instruction on inhalation techniques may contribute to adherence to inhalation therapy through decreasing intentional nonadherence. Furthermore, good adherence to the therapeutic regimen may offer good asthma-related outcomes.

PurposeAdherence to inhalation therapy is a critical determinant of the success of chronic obstructive pulmonary disease (COPD) management. However, in practice, nonadherence to inhalation therapy is very common in COPD patients. The effects of adherence to inhalation therapy in COPD have not been fully studied, and less is known about the relationship between medication adherence and quality of life in COPD. Our aim is to assess the factors that contribute to adherence to inhalation therapy and examine their correlation with quality of life.Patients and methodsA cross-sectional analysis of 88 COPD patients was performed using a self-reported adherence questionnaire with responses on a 5-point Likert scale.ResultsOf the 88 patients who were potential participants, 55 (63%) responded with usable information. The only significant factor associated with the overall mean adherence score was receiving repeated instruction about inhalation techniques (P = 0.032). Of the 55 respondents, 22 (40.0%) were given repeated verbal instruction and/or demonstrations of inhalation technique by a respiratory physician. Significant correlations were found between the overall mean adherence score and the health-related quality of life score (St George’s Respiratory Questionnaire: total, r = −0.35, P = 0.023; symptoms, r = −0.43, P = 0.002; impacts, r = −0.35, P = 0.011). Furthermore, patients with repeated instruction showed better quality of life scores than those who did not receive instruction (total, P = 0.030; symptoms, P = 0.038; impacts, P = 0.019).ConclusionsRepeated instruction for inhalation techniques may contribute to adherence to therapeutic regimens, which relates to better health status in COPD.

HRCT patterns at diagnosis can help predict the prognosis of patients with PM/DM-ILD as well as the presence of anti-CADM-140.

IntroductionNonadherence to inhalation therapy is very common in patients with chronic obstructive pulmonary disease (COPD). Few data are available to support the role of community pharmacists in optimizing inhalation therapy in COPD patients. Since 2007, the Kitano Hospital and the Kita-ku Pharmaceutical Association have provided a network system for delivering correct inhalation techniques through certified community pharmacists. The effects of this network system on clinical outcomes in COPD patients were examined.MethodsA total of 88 consecutive outpatients with COPD at baseline and 82 of those 4 years later were recruited from the respiratory clinic of Kitano Hospital Medical Research Institute. Measurements included the frequency of COPD exacerbations, patients’ adherence to inhalation therapy using a five-point Likert scale questionnaire, and patients’ health status both prior to this system and 4 years later.ResultsUsable information was obtained from 55 patients with COPD at baseline, and from 51 patients 4 years later. Compared with baseline values, a significant decrease was observed in the frequency of COPD exacerbations (1.5 ± 1.6 versus 0.8 ± 1.4 times/year, P = 0.017). Adherence to the inhalation regimen increased significantly (4.1 ± 0.7 versus 4.4 ± 0.8, P = 0.024), but health status was unchanged. At 4 years, of 51 COPD patients, 39 (76%) patients who visited the certified pharmacies showed significantly higher medication adherence than those who did not (4.6 ± 0.6 versus 3.9 ± 1.0, P = 0.022).ConclusionThe network system may improve COPD control and adherence to inhalation regimens.

Objective We identified the prognostic relevance of pneumothorax in interstitial lung disease (ILD) patients and evaluated the efficacy and safety of autologous blood-patch pleurodesis. Methods We retrospectively reviewed 59 occurrences of pneumothorax in 34 ILD patients identified over a 12-year period. Results Air leakage ceased in 16 of 22 (72.7%) episodes after blood pleurodesis and in 11 of 14 (78.6%) episodes after chemical pleurodesis. Both the cure ratio and recurrence ratio in the cure episodes were comparable with those in the chemical pleurodesis group (p=0.99 and 0.99, respectively). In addition, there were no harmful events associated with blood pleurodesis. The median survival time after the first episode of pneumothorax was less than 9 months in patients with idiopathic interstitial pneumonia (IIP) and only around 3 years in the patients with other types of ILD, which have essentially favorable outcomes. Kaplan-Meier survival estimates were significantly worse in the patients with concomitant pneumomediastinum than in those without (p<0.05). A multivariate Cox regression analysis identified that the number of episodes of pneumothorax, IIP diagnosis and concomitant pneumomediastinum were independent predictors of death. Conclusion Autologous blood-patch pleurodesis is safe and worth considering as a first-line treatment for pneumothorax secondary to ILD. However, despite treatments, the prognosis after the onset of pneumothorax in ILD patients was found to be poor. In addition, concomitant pneumomediastinum may further worsen the prognosis.
