No previous study has evaluated the effects of RF on inflammatory and hematological indices of COPD patients. The main objective of the present pilot study was to assess the effects of RF on some inflammatory and hematological indices measured in male patients with stable COPD. Fifteen COPD patients (mean ± SD of age: 71 ± 6 years) who fasted during Ramadan 2017 volunteered for the study. Three sessions (Before-Ramadan, End-Ramadan and After-Ramadan) were selected. Spirometry tests and blood samples were consistently performed 2.5–4.5 hr before the interruption of the fasting. Assessment sessions comprised: spirometry, inflammatory [erythrocyte sedimentation rate (ESR); C-reactive protein (CRP)] and hematological [red and white blood cells (RBC, WBC); hemoglobin; hematocrit; mean corpuscular volume; mean corpuscular hemoglobin; platelets] indices. Findings were analyzed by applying Friedman ANOVA. The median (lower–upper quartiles) of ESR (Before-Ramadan: 3 (2–9), End-Ramadan: 7 (0–13), After-Ramadan: 9 (5–15) mm/h) and CRP (Before-Ramadan: 20 (11–38), End-Ramadan: 15 (9–34), After-Ramadan: 20 (12–46) mg/L) were not significantly affected by RF. Among all the hematological indices, RF influenced only hemoglobin (Before-Ramadan: 14.4 ± 2.2, End-Ramadan: 13.4 ± 1.3, After-Ramadan: 12.2 ± 0.9 g/dL), hematocrit (Before-Ramadan: 45 ± 7, End-Ramadan: 40 ± 4, After-Ramadan: 39 ± 4%), RBC (Before-Ramadan: 5.1 ± 1.0, End-Ramadan: 4.6 ± 0.7, After-Ramadan: 4.4 ± 0.5 106/mm3) and WBC (Before-Ramadan: 8,673 ± 1,911, End-Ramadan: 7,840 ± 1,526, After-Ramadan: 9,507 ± 2,190/mm3). Compared to the Before-Ramadan session, the End-Ramadan session values for hemoglobin, hematocrit, RBC and WBC were lower. Compared to the After-Ramadan session, the End-Ramadan session values for hemoglobin and WBC were higher and lower, respectively. In conclusion, RF caused significant reduction in hemoglobin, hematocrit, RBC and WBC. However, it did not induce any significant changes in the CRP and ESR indices.

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.

Early detection of alteration of muscle strength, quantity, and quality, and sarcopenia is useful in non-cirrhotic chronic hepatitis B (NC-CHB) patients. Studies, which explored the handgrip strength (HGS) are scarce with questionable results, and no previous case-control study explored the presence of sarcopenia. The aim of this study was to assess the muscle strength [i.e.; HGS absolute (HGS A ), HGS A /body mass index (BMI)], muscle quantity [i.e.; appendicular skeletal muscle (ASM), ASM/height 2 , ASM/total body weight (TBW), ASM/BMI], and muscle quality [i.e.; HGS A /total muscle mass (TMM), HGS A /ASM] of NC-CHB patients. This was a case-control study. Cases ( n = 26) were untreated NC-CHB patients, and controls ( n = 28) were ‘apparently’ healthy participants. Muscle mass was estimated via the TMM (kg) and ASM (kg). Muscle strength was evaluated via the HGS data [i.e.; HGS A (kg), HGS A /BMI (m 2 )]. Six variants of HGS A were determined: highest values for the dominant and non-dominant hands, highest value between the two hands, averages of the three measurements for the two hands, and the average of the highest values of the two hands. Muscle quantity was expressed in three relative variants (ASM/height 2 , ASM/TBW, and ASM/BMI). Muscle quality was evaluated via relative HGS data adjusted by muscle mass (i.e.; HGS A /TMM, HGS A /ASM). Probable and confirmed sarcopenia were retained in front of low muscle strength, and low muscle strength and muscle quantity or quality, respectively. There were no significant differences between controls and NC-CHB patients in values of muscle i) Strength whatever the HGS’ mode of expression (e.g.; HGS A /BMI: 1.59 ± 0.54 vs. 1.53 ± 0.54 m 2 , p = 0.622, respectively), ii) Quantity (e.g.; ASM/BMI: 0.79 ± 0.24 vs. 0.77 ± 0.23 m 2 , p = 0.883), and iii) Quality (e.g.; HGS A /ASM: 2.00 ± 0.25 vs. 2.01 ± 0.41, p = 0.952, respectively). One NC-CHB participant had a confirmed sarcopenia. To conclude, both controls and NC-CHB patients had similar HGS values. Only one NC-CHB patient had a confirmed sarcopenia.
