No prior study has evaluated the impacts of Ramadan intermittent fasting (RIF) on oxidant/antioxidant stress (OS/AOS) biomarkers in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to assess the impacts of RIF on some OS/AOS biomarkers measured in male patients with stable COPD. Fifteen COPD patients (mean age: 71 ± 6 years) fasting Ramadan in 2017 volunteered to take part in the study. Three sessions (before Ramadan [BR], end Ramadan [ER], after Ramadan [AR]) were selected. Blood samples of OS (homocysteine [μmol/L], thiobarbituric acid reactive substances [TBARS, μmol/L]) and AOS (catalase [U/ml], ceruloplasmin [g/L], superoxide dismutase [SOD, ng/ml], zinc [µmol/L], albumin [g/L]) biomarkers were consistently taken 4.5 to 2.5 hr before the iftar . Findings were analyzed by applying Friedman or Kruskal–Wallis ANOVA. Comparisons of the number of patients with high OS [high homocysteine and/or TBARS] and low AOS (low catalase and/or ceruloplasmin and/or SOD and/or zinc and/or albumin) blood values between the three sessions were performed using the Cochran test. The median ± interquartile of homocysteine (BR: 21.48 [18.98–24.49], ER: 23.15 [21.77–26.45], AR: 24.87 [21.91–37.12]), ceruloplasmin (BR: 0.27 [0.24–0.30], ER: 0.28 [0.26–0.33], AR: 0.28 [0.25–0.32]), SOD (BR: 288.00 [112.00–400.00], ER: 182.00 [152.00–386.00], AR: 234.00 [190.00–420.00]) and the mean ± SD of TBARS (BR: 5.66 ± 1.26, ER: 4.59 ± 0.78, AR: 5.29 ± 1.69), catalase (BR: 120.97 ± 54.62, ER: 106.73 ± 50.92, AR: 137.39 ± 40.88), zinc (BR: 11.85 ± 2.01, ER: 12.47 ± 2.34, AR: 12.21 ± 2.58) and albumin (BR: 39.78 ± 3.19, ER: 40.74 ± 2.26, AR: 40.56 ± 2.38) were not significantly affected by RIF. The number of patients with high OS (BR [ n = 13], ER [ n = 15], AR [ n = 14]) or low AOS (BR [ n = 12], ER [ n = 13], AR [ n = 13]) statuses were not significantly influenced by RIF. In conclusion, RIF did not induce any significant statistical or clinical changes in OS/AOS biomarkers or statuses in COPD patients.

“…A minimal 20-year RIF experience was applied as an inclusion criterion . It is possible, as seen in studies assessing the effects of RIF on healthy patients’ exercise performance ( Chtourou et al, 2012 ), that the RIF record of the patients could influence their respiratory adaptations ( Ben Saad, 2016 ; Fenneni et al, 2015 ). This point was not considered in several related studies including healthy or asthmatic patients ( Abdel-aziz & Ibraheem, 2008 ; Adeli et al, 2015 ; Askari et al, 2016 ; Moosavi et al, 2007 ; Siddiqui et al, 2005 ; Singha Roy & Bandyopadhyay, 2016 ; Soori et al, 2016 ; Subhan et al, 2006 ; Norouzy et al, 2013 ).…”

“…All included COPD patients were ex-smokers. This is a serious point to highlight ( Ben Saad, 2016 ), because smokers compared with ex-smokers, are more irritable during Ramadan ( Kadri et al, 2000 ) and psychological stress has proved to influence pulmonary function ( Kang & Fox, 2000 ). This information was neglected in some relative studies ( Adeli et al, 2015 ; Duncan et al, 1990 ; Norouzy et al, 2013 ; Siddiqui et al, 2005 ; Singha Roy & Bandyopadhyay, 2016 ; Subhan et al, 2006 ).…”

No previous study has raised the effects of RIF on lung function data of chronic obstructive pulmonary disease (COPD) patients. The objective of the present study was to assess the effects of RIF on spirometric data measured in male patients with a stable COPD. Sixteen patients with stable COPD (mean ± SD of age: 64 ± 7 years) who fasted during Ramadan volunteered to the study. Three sessions (Before-R, End-R, and After-R) were selected for spirometry tests that were consistently performed 2.5–4.5 hr before fasting break. Assessment sessions comprised: forced vital capacity (FVC), 1st s forced expiratory volume (FEV1), FEV1/FVC, peak expiratory flow (PEF), maximal mid-expiratory flow (MMEF), and forced expiratory flow rate at the x% of FVC to be exhaled (FEFx%). A reversibility test was performed only during the Before-Ramadan session. Spirometric data were expressed in percentages of local reference values. Findings were analyzed by applying repeated measures analysis of variance. The mean ± SD of the postbronchodilator FEV1/FVC ratio and the FEV1 were, respectively, 0.52 ± 0.14 and 48 ± 19%. The mean ± SD of FEV1 (Before-R: 47 ± 19, End-R: 45 ± 18, After-R: 44 ± 19%), FVC (Before-R: 73 ± 18, End-R: 71 ± 16, After-R: 69 ± 17%), FEV1/FVC (Before-R: 67 ± 16, End-R: 66 ± 16, After-R: 65 ± 16%), PEF (Before-R: 46 ± 19, End-R: 47 ± 22, After-R: 45 ± 21%), MMEF (Before-R: 19 ± 10, End-R: 18 ± 8, After-R: 18 ± 9%), FEF25% (Before-R: 16 ± 6, End-R: 16 ± 5, After-R: 15 ± 5%), FEF50% (Before-R: 21 ± 14, End-R: 20 ± 12, After-R: 20 ± 12%) and FEF75% (Before-R: 27 ± 19, End-R: 27 ± 19, After-R: 27 ± 19%) were not significantly influenced by RIF. RIF did not bring about any significant changes in the spirometric data of stable COPD male patients fasting the 2016 holy month of Ramadan.

“…The methodology of the above six studies included some issues concerning the study design and spirometric measurements (Ben Saad, 2016; Subhan, 2008). First, readers were faced with a variety of unknown information concerning Ramadan year (Duncan et al, 1990), ambient temperature and relative humidity at the time of spirometric tests (Moosavi et al, 2007; Siddiqui et al, 2005; Roy & Bandyopadhyay, 2016), and the elapsed time between dawn and sunset (Duncan et al, 1990; Moosavi et al, 2007; Roy & Bandyopadhyay, 2016; Siddiqui et al, 2005; Subhan et al, 2006).…”

The few studies carried out on the effects of Ramadan fasting (RF) on spirometric values present contradictory conclusions. This study aimed at assessing whether RF affects healthy adults’ spirometric values. Twenty-nine nonsmoking healthy males (M ± standard error of mean [SEM] of age: 27 ± 1 years) who fasted during Ramadan (June 29-July 28, 2014) volunteered to the study. Three periods (before-Ramadan [June 23-25], mid-Ramadan [July 14-16] and after-Ramadan [August 11-14]) were selected for spirometry measurements that were consistently performed 5.5 to 3.5 hours (between 15:00 and 17:00 hours) before fasting break. Assessment sessions comprised following: weight (kg), forced vital capacity (FVC), first second expiratory volume (FEV1), FEV1/FVC, peak expiratory flow (PEF), maximal mid expiratory flow (MMEF), and forced expiratory flow rate at the x% of FVC to be exhaled (FEFx%). Spirometric data were expressed in percentages of reference values. Results were analyzed by applying repeated measures analysis of variance. The M ± SEM of weight (before-R: 81.6 ± 2.8 kg, mid-R: 80.8 ± 2.9 kg, after-R: 81.2 ± 2.9 kg), FEV1 (before-R: 99 ± 2%, mid-R: 98 ± 2%, after-R: 98 ± 2%), FVC (before-R: 103 ± 2%, mid-R: 101 ± 2%, after-R: 101 ± 2%), PEF (before-R: 112 ± 3%, mid-R: 113 ± 2%, after-R: 114 ± 3%), MMEF (before-R: 83 ± 3%, mid-R: 83 ± 3%, after-R: 82 ± 3%), FEF25% (before-R: 90 ± 5%, mid-R: 89 ± 6%, after-R: 87 ± 6%), FEF50% (before-R: 94 ± 4%, mid-R: 91 ± 4%, after-R: 93 ± 3%), and FEF75% (before-R: 108 ± 3%, mid-R: 111 ± 2%, after-R:111 ± 3%) were not significantly influenced by RF. To conclude, RF did not bring about any significant changes in the spirometric values of nonsmoking healthy adult males.
