BackgroundSince pulmonary hypertension (PH) in patients with chronic obstructive pulmonary diseases (COPD) causes poor prognosis and inflammatory process involved in PH, it is supposed that Statins with anti-inflammatory effects might be useful in the treatment of PH.ObjectivesThe aim of this study was to evaluate the influence of Atorvastatin on the treatment of pulmonary hypertension in patients with COPD.Patients and MethodsA registered (IRCT201108257411N1), triple-blind, randomized controlled trial was performed in Rasoule Akram hospital, Tehran, from 2009 to 2011. Forty five patients with secondary pulmonary hypertension due to COPD were recruited and randomized to two groups receiving either Atorvastatin 40 mg/d or placebo in addition to their current treatment for 6 months. The outcomes including systolic pulmonary arterial hypertension (SPAH), cardiac output (CO), right ventricular size (RVS), CRP, 6 min walk distance test (6MWD), and spirometry parameters were measured after 6 months.ResultsBaseline characteristics were similar in both groups. After 6 months, pulmonary hypertension changed from 48.5 ± 6.9 to 42.9 ± 9.3 mmHg for Atorvastatin users and from 49.7 ± 11.4 to 48.2 ± 14.6 mmHg for Placebo users (P = 0.19, CI - 13.57 - 2.89), 6MWD after 6 months was 339 ± 155 meters in case group versus 340 ± 106 meters in control group (P = 0.98, CI - 92.58 - 91.15). There were no significant changes in other outcomes including CRP, RVS, CO and spirometry parameters.ConclusionsAlthough we found a trend towards decreasing SPAH and improving 6MWD, no statistically significant shift were detected in our outcomes due to inadequate sample size.
Background:Chronic obstructive pulmonary disease (COPD) is one of the most important causes of disability and mortality in the world. Although cigarette smoking and environmental pollutants have been recognized as the major causes of COPD, the role of infection in the pathogenesis and progression of COPD has also been reported.Objectives:The aim of the present study was to find the relationship between Helicobacter Pylori infection and COPD through anti H. pylori IgG serology, real time PCR of bronchoalveolar lavage and trans bronchial biopsy urease tests.Patients and Methods:This descriptive cross-sectional study was carried out on 60 adults with COPD. After obtaining the patient’s history, physical examination, spirometry and confirmation of COPD diagnosis by pulmonologist, subjects were selected through convenience sampling. In order to determine the severity and prognosis of disease, the global initiative for chronic obstructive lung disease (GOLD) criteria and BODE index were used. Subjects underwent bronchoscopy for obtaining bronchoalveolar lavage (BAL) samples and biopsy was performed. Biopsy and BAL samples were investigated respectively by urease test and real time PCR. Moreover, patients’ serum samples were serologically studied for detection of anti H. pylori IgG.Results:Mean age of the participants was 60.65 ± 9.15 years, and 25% were female and 75% were male. The prevalence rate of H. pylori in COPD patients was 10% according to real time PCR, 88.3% according to the serology test and 0% based on the urease test. According to the results of PCR and considering the severity of disease based on the GOLD criteria, from those with a positive PCR, one patient (16.6%) had very severe obstruction, three (50%) had severe obstruction and two patients (33.3%) had moderate obstruction. The relationship between H. pylori presence (based on PCR) and disease severity and prognosis was not statistically significant.Conclusions:These findings can justify the hypothesis of direct injury and chronic inflammation via inhalation and aspiration resulting in H. pylori colonization. In fact, it is thought that H. Pylori infection, beside the host genetic vulnerability and other environmental risk factors might make the patient susceptible to COPD or lead to COPD worsening. Although we found H. pylori infection in some patients with COPD, the results of this study, could not explain the pathogenic mechanisms of COPD.
In Covid-19 pandemic, specific comorbidities are associated with the increased risk of worse outcomes and increased severity of lung injury and mortality. the aim of this study was to investigate the effects of antihypertensive medications on the severity and outcomes of hypertensive patients with COVID-19. This retrospective observational study conducted on patients with COVID-19 who referred to Afzalipour Hospital, Kerman, Iran during the six months from 19 February 2020 to 20 July 2020. The data were collected through medical chart reviews. We assessed 265 patients with Covid-19 and they stratified based on hypertension and type of antihypertension medications. The data were described and Student’s t -test, Mann–Whitney U and Fisher exact test were run to compare the patients ‘demographical and clinical information. The qualitative variables were compared using the by SPSS software version 23. The results of the present study showed that hypertension was a prevalent comorbidity among patients with COVID-19 and hypertensive patients compared to other patients without any comorbidity who were older ( P -value: 0.03). The oxygen saturation was higher for the patients in the control group than hypertensive patients ( P -value: 0.01). The severity of COVID-19 and its outcome were not different between the patients who took or did not take antihypertensive medications and also the type of antihypertensive medications. Hypertensive patients did not show any significant difference in survival, hospital stay, ICU admission, disease severity, and invasive medical ventilation in other normotensive patients with COVID-19.
Background: Chronic obstructive pulmonary disease (COPD) is a major health issue worldwide. Introduction: This study aimed to evaluate the effect of aerobic exercises at steep surfaces on Apo A1 and Apo B serum levels and their ratio in COPD patients. Methods: This interventional study was undertaken on 16 COPD patients. The sample was selected by using the random sampling method. Patients were randomly divided into 2 groups of 8 members: uphill and downhill. Spirometry was conducted prior to the exercises and pulmonary volumes were measured. Aerobic exercises (stationary bicycle and treadmill) were started 3 times a week for 8 weeks. The duration of exercises in each session was determined based on the patients’ ability (30-40 min). In the first and second group, exercises were performed on sloped surfaces that were downwards and upwards at a 10-degree angle, respectively. Blood samples were taken from the patients before and after the 8 weeks. Apo A1 and Apo B serum levels and Apo A1 to Apo B ratio were measured. Data were analyzed by SPSS software. P<0.05 was considered statistically significant. Results: ApoA1/Apo B ratio in the uphill group before and after the intervention was 1.43±0.21 and 1.53±0.24 mg/dL, respectively, with P-value=0.36. In the downhill group, this value was 1.27±0.17 and 1.30±0.18, respectively, with a P-value=0.032. Conclusion: In light of the results of the present study, incorporating downhill exercises in COPD patients' rehabilitation program can help improve pulmonary function and prevent atherosclerotic events.
