The aim of this study was to characterise adherence in an adult population with cystic fibrosis (CF) and to investigate if variation in lung function was a predictor of adherence to treatment.The adherence of patients aged ≥16 years from an adult CF centre was measured by medication possession ratio (MPR) and self-report. Patients were assigned to one of three adherence categories (<50%, 50 to <80%, ≥80%) by their composite score (MPR). Ordinal regression was used to identify predictors of adherence, including coefficient variation measures for forced expiratory volume in 1 s (FEV1), weight and C-reactive protein concentration, measured from 6 months and 12 months before baseline.MPR data for 106 of 249 patients (mean age 29.8±9.2 years) was retrieved, indicating a mean adherence of 63%. The coefficient of variation for FEV1 was inversely related to adherence and was a univariate predictor of adherence (6 months: OR 0.92, 95% CI 0.87–0.98, p=0.005; 12 months: OR 0.94, 95% CI 0.93–0.99, p=0.03) and remained significant in the final models. The coefficient of variation of weight and C-reactive protein were not predictive of adherence.The coefficient of variation of FEV1 was identified as an objective predictor of adherence. Further evaluation of this potential marker of adherence is now required.

BackgroundExposure to zinc was suggested to be associated with pulmonary damage, but whether zinc exposure affects lung function remains unclear.ObjectivesTo quantify the association between urinary zinc and lung function and explore the potential mechanisms.MethodsUrinary zinc and lung function were measured in 3917 adults from the Wuhan-Zhuhai cohort and were repeated after 3 years of follow-up. Indicators of systemic inflammation (C reactive protein), lung epithelium integrity (club cell secretory protein-16) and oxidative damage (8-hydroxy-2′-deoxyguanosine and 8-isoprostane) were measured at baseline. Linear mixed models were used to estimate the exposure–response relationship between urinary zinc and lung function. Mediation analyses were conducted to assess mediating roles of inflammation and oxidative damage in above relationships.ResultsEach 1-unit increase in log-transformed urinary zinc values was associated with a 35.72 mL decrease in forced vital capacity (FVC) and a 24.89 mL decrease in forced expiratory volume in 1 s (FEV1) in the baseline analyses. In the follow-up analyses, there was a negative association between urinary zinc and FVC among participants with persistent high urinary zinc levels, with an estimated change of −93.31 mL (95% CI −178.47 to −8.14). Furthermore, urinary zinc was positively associated with restrictive ventilatory impairment. The mediation analyses suggested that C reactive protein mediated 8.62% and 8.71% of the associations of urinary zinc with FVC and FEV1, respectively.ConclusionUrinary zinc was negatively associated with lung function, and the systemic inflammation may be one of the underlying mechanisms.

Cystic fibrosis (CF) is a genetic disease characterized by progressive decline of lung function and chronic airway inflammation. Adipose tissue, through adiponectin and leptin, exerts several effects on energy metabolism and inflammatory processes. This study evaluated the levels of adiponectin and leptin in adult healthy subjects, in patients with CF and their correlation with long-term physical activity. CF patients were divided into two groups (sedentary versus active) based on their regular physical activity over 3 years. Anthropometric and serum biochemical profiles of CF patients and controls were evaluated and compared. Total serum adiponectin and leptin levels were measured by ELISA; adiponectin oligomeric profiles were analysed by western blot. Adiponectin levels were significantly higher while leptin levels were lower in patients with CF than in healthy controls. Furthermore, adiponectin was significantly lower in active compared to sedentary CF (p=0.047), while leptin was slightly increased in active compared to sedentary CF. In addition, C-reactive protein levels were significantly lower in active than in sedentary CF patients (p=0.048). Interestingly, only in the active group adiponectin levels were inversely correlated with forced expiratory volume (FEV) 1% decrease/year and FEV1% decrease. Moreover, adiponectin levels negatively correlated with lipid profiles. Our findings indicated that regular, long-term physical activity in CF improves respiratory function, metabolism, and inflammation status. These improvements in patients’ conditions are associated with immunometabolic processes involving adiponectin, leptin, and C-reactive protein. Therefore, we propose that both adipokines may be a useful biomarker in the evaluation of metabolic and inflammatory status in patients with CF.

The treatment of cystic fibrosis (CF) patients homozygous for the F508del mutation with Orkambi®, a combination of a corrector (lumacaftor) and a potentiator (ivacaftor) of the mutated CFTR protein, resulted in some amelioration of the respiratory function. However, a great variability in the clinical response was also observed. The aim of this study was to evaluate the response to Orkambi® in a small cohort of F508del/F508del patients (n = 14) in terms of clinical and laboratory parameters, including ex vivo CFTR activity in mononuclear cells (MNCs), during a 12-month treatment. Patients responded with an increase in percent predicted forced expiratory volume in 1 s (FEV1%) and body mass index (BMI) as well as with a decrease in white blood cell (WBC) total counts and serum C-reactive protein (CRP) levels, although not significantly. Sweat chloride and CFTR-dependent chloride efflux were found to decrease and increase, respectively, as compared with pre-therapy values. CFTR and BMI showed a statistically significant correlation during Orkambi® treatment. Clustering analysis showed that CFTR, BMI, sweat chloride, FEV1%, and WBC were strongly associated. These data support the notion that CFTR-dependent chloride efflux in MNCs should be investigated as a sensitive outcome measure of Orkambi® treatment in CF patients.

Background: Sulfur mustard (SM) is a chemical warfare agent that can cause serious pulmonary complications. This study was designed to determine serum highly sensitive C-reactive protein (hs-CRP) and evaluate its correlation with lung function parameters in patients with chronic obstructive pulmonary disease (COPD) due to SM poisoning. Methods: Fifty consecutive SM patients with stable COPD and a mean age 46.3 ± 9.18 years were enrolled in this cross sectional study. Thirty healthy men were selected as controls. Lung function parameters were evaluated. Serum hs-CRP by immunoturbidometry assay was measured in both the patients and controls. Results: In the case group, the mean forced expiratory volume in one second (FEV1) was 2.14 ± 0.76 L (58.98% ± 17.51% predicted). The mean serum hs-CRP was 9.4 ± 6.78 SD and 3.9 ± 1.92 SD mg/L in the cases and controls, respectively, with significant statistical differences (p < .001). There was negative correlation between the serum hs-CRP and FEV1 levels (p = .01). The serum hs-CRP levels were also correlated with Global Initiative for Chronic Obstructive Lung disease (GOLD) stages (r = .45, p < .001). Conclusions: Our findings suggest that the serum hs-CRP level is increased in SM patients with COPD and may have a direct correlation with disease severity. It may then be used as a marker for the severity of COPD in patients with SM poisoning.

Objective: The aim of this study was to investigate the characteristics associated with alcohol co-ingestion by measuring blood alcohol concentration in patients visited to the emergency department with deliberate self-poisoning. Also, it was to evaluate the accuracy of self-reported alcohol ingestion. Methods: The initial assessment forms, medical records and laboratory tests of patients visited to the ED after DSP between March 2017 and June 2020 were retrospectively reviewed. Based on the patients’ BAC, two groups were formed: the non-alcohol group and the alcohol group. Results: This study included 286 patients (56.6%, n = 162) in the non-alcohol group and 43.4% (n = 124) in the alcohol group. In multivariate logistic analysis, alcohol co-ingestion was independently associated with no history of psychiatric admission (Odds Ratio = 6.222, 95% Confidence Interval = 1.148-33.716, P = 0.034), lactate (mg/dL)(Odds Ratio = 1.961, 95% Confidence Interval = 1.274-3.019, P = 0.002), and C-reactive protein level (mg/dL) (Odds Ratio = 0.003, 95% Confidence Interval = 0.000-0.897, P = 0.046). The receiver operating characteristics analysis of lactate value for the association with alcohol co-ingestion showed a cutoff value of 1.45, with 88.1% sensitivity, 71.6%specificity, and an area under the curve of 0.845. There was no statistically significant difference in emergency department disposition between the two groups. Using the 261 subjects who completed the self-report of alcohol co-ingestion, self-report resulted in 77.6% sensitivity and 76.6% specificity for the assessment of alcohol co-ingestion. The positive and negative predictive values for self-reporting were 72.6% and 81.0%, respectively. Conclusions: Alcohol co-ingestion was associated with no history of psychiatric ward admission, high lactate levels, and low C-reactive protein values in patients who visited the emergency department with deliberate self-poisoning. This study showed that self-reported alcohol co-ingestion was not a substitute for the blood alcohol concentration test.
