Öğe Acquired atopic disease after liver transplantation in children; similarities to and differences from adults: a preliminary study(Lippincott Williams & Wilkins, 2014) Topal, Erdem; Catal, Ferhat; Selimoglu, Mukadder Ayse; Karabiber, Hamza; Kilic, Talat; Baskiran, Adil; Senbaba, ElifObjective The aim of this study was to determine the similarities and differences in the frequency and follow-ups of newly diagnosed atopic diseases after liver transplantation in pediatric and adult patients. Materials and methods Patients who underwent liver transplants between 2005 and 2013 and who are still alive were enrolled in the study. Patients who came for checkups filled out a survey evaluating atopic diseases. Those who had an atopic disease before transplantation were excluded from the study. Results A total of 165 patients were enrolled in this study; 114 (69.1%) were males and 29 (17.6%) were children. The average transplantation age was 40.8 (0.3-67) years, and the most frequent reason for transplantation was chronic viral hepatitis. In 22 patients, atopic diseases [allergic rhinitis in nine patients (5.5%), asthma in six patients (3.9%), atopic eczema in six patients (3.9%), food allergy in six patients (3.9%), and drug allergy in one patient (0.6%)] developed after transplantation. Atopic diseases after transplantation were more common in children (P=0.03). When the atopic diseases were examined on a case-bycase basis, there were no differences between children and adults with respect to asthma (P=0.284), allergic rhinitis P=1.0), or atopic eczema (P=0.284), but food allergy (P=0.009) and peripheral eosinophilia (P=0.002) were more common in children. The periodicity of allergic diseases after transplantation (P=0.192) and total IgE levels (P=0.086) were similar. Conclusion Atopic diseases developed after liver transplantation and had a greater impact on children than adults. Therefore, after undergoing liver transplantation, patients should be monitored closely for signs of atopic diseases.

The aim of this study was to compare the following factors among factory-made cigarette (FMC) smokers, hand-rolled cigarette (HRC) smokers and non-smokers (NS): demographic characteristics, pulmonary function testing (PFT) and carboxyhemoglobin (COHb) levels. PFT included checking: forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, forced expiratory flow from 25-75% of the vital capacity (FEF25-75) and peak expiratory flow (PEF). We wanted to determine the impact of smoking on pulmonary function testing and to determine any differences in PFTs and COHb levels between FMC and HRC smokers. A total of 182 participants (all males) were included in the study. The subjects in the study were randomly chosen from emergency service admissions which had complaints other than respiratory system. The mean age of study subjects was 40.8 (range: 22-92) years. Mean age of starting smoking among HRC smokers was not significantly different from FMC smokers (95% CI: -0.55-2.37, p=0.220). HRC smokers had significantly lower economic and education levels than FMC smokers (95% CI: 9.0-45.2, p<0.01). NS had highest economic and educational levels (95% CI: 35.9-66.6, p<0.01) of the 3 study groups. The mean [+/- standard deviation(SD)] FEV1/FVC was 76.66 (+/- 7.45) among FMC smokers (95% CI: 74.82-78.51), 77.36 (+/- 8.14) among HRC smokers (95% CI: 75.36-79.36) and 83.13 (+/- 5.08) among NS (95% CI: 81.70-84.56, p<0.01). The mean (+/- SD) FEV1 was 84.50 (+/- 17.80) among FMC smokers (95% CI: 80.12-88.92 ), 89.4 (+/- 15.8) among HRC smokers (95% CI: 85.56-93.32) and 95.30 (+/- 13.3) among NS (95% CI: 91.59-99.07, p<0.01). The mean (+/- SD) PEF was 81.90 (+/- 19.30) among HRC smokers (95% CI: 77.19-86.69), 78.10 (+/- 18.70) among FMC smokers (95% CI: 73.47-82.74) and 86.20 (+/- 16.0) among NS (95% CI: 81.70-90.69, p=0.06). The mean FVC, FEV1, FEV1/FVC, FEF25-75%, and PEF values among NS were significantly (p<0.05) higher for each variable than the mean of these values among FMC and HRC smokers. The mean COHb level among NS was significantly (p<0.05) lower than the mean COHb levels in the two smoking groups. There were no significant differences in PFT results or COHb levels between the two smoking groups (p>0.05).

In this study, we aimed to investigate the effect of long-term oxygen therapy on patients with stage 4 COPD who were followed up and treated at the polyclinic or clinic service. We evaluated the effects of oxygen therapy on energy metabolism and physical activity in patients with COPD. Methods: Nineteen patients with COPD (16 male/3 female), treated with oxygen therapy for the first time, were included in this study. Analysis of arterial blood gases and pulmonary function test was performed. Metabolic Holter device (SenseWear (R) Armband) was placed pre- and post-oxygen therapy on the patients' arm for at least 3 days. This device captures Holter data in a digitized electronic system, and the daily average value was calculated from the data. Results: Post-oxygen treatment showed a significant increase in energy expenditure by patients with COPD (pretreatment, 1,497 +/- 596 joule; posttreatment, 2,977 +/- 5,985 joule; P=0.044). Moreover, number of steps during walking (pretreatment, 2,056 +/- 256; posttreatment, 2,120 +/- 195; P=0.03), resting (pretreatment, 6.36 +/- 3.31 hours; posttreatment, 3.47 +/- 2.19 hours; P<0.03), and sleeping (pretreatment, 4.23 +/- 2.13 hours; posttreatment, 2.33 +/- 1.42 hours; P<0.00) showed significant differences. Increased daily energy expenditure in patients with respiratory failure was detected with long-term oxygen therapy. In addition, the immobility of patients decreased and duration of physical activity increased in patients with COPD. Conclusion: In this study, positive effects of long-term oxygen therapy have been demonstrated with respect to energy metabolism and physical activity of patients with COPD. Thus, we recommend that medication adherence and long-term oxygen therapy should begin early in patients with COPD.Öğe Evaluation of erectile dysfunction in patients with asthma(Wiley, 2021) Kilic, Talat; Kilic Aydin, Naciye; Kirici Berber, Nurcan; Kaya, OmerObjectives The aim of the current study was to investigate Erectile dysfunction (ED) in asthma patients without comorbidity and the relationship between the level of asthma control and ED. Methods Forty male patients aged 24-50 years with controlled-to-uncontrolled asthma and 20 healthy volunteers were included in this study. The International Index of Erectile Function Questionnaire (IIEF) for ED was used. Results Evaluation of the IIEF scores for ED showed that 23 (57.5%) of the asthma patients and 4 (20.0%) of the controls had various degrees of ED, and the difference was statistically significant. In total, 25% of asthma patients had mild ED, 22.5% moderate ED, and 10% severe ED. Severe, moderate and mild ED was more frequent in the asthma group. Of the 23 patients who had various degrees of ED, 13 were in the uncontrolled asthma group. While all asthma patients with severe ED were in the uncontrolled asthma group, of the 9 asthma patients with moderate ED, 6 were in the uncontrolled asthma group, 2 were in the partially controlled asthma group and one was in the controlled asthma group. Additionally, of the 10 asthma patients with mild ED, 3 were in the uncontrolled asthma group, 2 were in the partially controlled asthma group and 5 were in the controlled asthma group. Conclusion The current study showed that ED is frequent and more severe in asthma patients than controls with same age. A highly negative correlation was found between ED degree and asthma control severity.Öğe The Evaluation of Prick Test Results in Malatya(Derman Medical Publ, 2015) Kahraman, Hasan; Kilic, Talat; Sucakli, Mustafa HakiAim: Skin prick test used for determination of allergic diseases is an easy, cheap, safe, fast, and frequently utilized test. There are factors such as genetic tendency, climate, humidity, vegetation, and altitude affecting the development of allergy. Our goal is to determine the allergic susceptibility of allergic patient in Malatya province. Material and Method: The 403 patients who referred to our chest clinic in Malatya between January 2008 and June 2010 with complaint of respiratory allergic diseases including asthma and allergic rhinitis were retrospectively investigated. Skin prick test results were evaluated according to age and gender. Results: Of the 403 patients incorporated to the study, 177 (43.9%) were male, 226 (56.1%) were female. Most common reaction was against to grasses, in 78 patients (19.4%). The other common reactions were found against to grains, in 70 patients (17.4%); to D. Farinea in 51 patients (12.7%); to D Pteronyssinus in 44 patients (10.9%); to grass mix in 41 patients (10.2%). Although reactions were higher in men than in women, only against to D. Pteronyssinus was statistical significant (p=0.032). Reactions were observed most commonly in 10-19 age group and secondly in 20-29 age group. Discussion: Atopic patients in Malatya province should be careful especially against to grasses, grains, and house dust mites.Öğe Investigation of SARS-CoV-2 RNA in milk produced by women with COVID-19 and follow-up of their infants: A preliminary study(Wiley-Hindawi, 2021) Kilic, Talat; Kilic, Sebnem; Berber, Nurcan Kirici; Gunduz, Ayten; Ersoy, YaseminObjectives Studies have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is primarily transmitted from person to person via airborne droplets. It is unclear whether it can be shed into human milk and transmitted to a child via breastfeeding. We investigated the presence of SARS-CoV-2 RNA in human milk samples of 15 mothers with coronavirus disease 19 (COVID-19) and in the throat swab samples of their infants. Methods This is a prospective observational study in which breast milk samples were collected from 15 mothers with COVID-19. The presence of SARS-CoV-2 RNA in the whole human milk samples of the patients was investigated using RT-qPCR. All of the infants underwent a clinical follow-up during their 14-day isolation and their throat swab samples were tested for SARS-CoV-2 RNA. Results Of 15 mothers with COVID-19, SARS-CoV-2 RNA was detected in milk samples from 4 mothers. The throat swab samples from these mothers' infants were found to be positive for SARS-CoV-2 RNA. Three of the four mothers were breastfeeding. In addition, during the 14-day isolation, all but three of the mothers breastfed their infants. Of the 12 breastfed infants, while the test for SARS-CoV-2 RNA in throat swab samples was negative in 6 of the infants, the other 6 infants, who had mild COVID-19 symptoms, tested positive for SARS-CoV-2 RNA. Clinical outcomes of all mothers and infants were uneventful. Conclusion To our knowledge, this is the first case series with the largest number of cases with SARS-CoV-2 RNA positivity in human milk samples of mothers with COVID-19. However, we believe that the benefits of breastfeeding may outweigh the risk of SARS-CoV-2 infection in infants.Öğe Longitudinal pulmonary functional loss in cotton textile workers: A 5-year follow-up study(Int Scientific Literature, Inc, 2013) Kahraman, Hasan; Sucakli, Mustafa Haki; Kilic, Talat; Celik, Mustafa; Koksal, Nurhan; Ekerbicer, Hasan CetinBackground: Occupational exposure to cotton dust causes several diseases affecting the lungs, but only limited information is available on effects of long-term exposure. In this study, we aimed to evaluate longitudinal changes in selected parameters of pulmonary function in textile workers. Material/Methods: This prospective cohort study began with 196 textile workers in 2006 and was completed in 2011 with 49 workers. We used standardized tests for pulmonary function on participants on the first day of the workweek in June of 2006 and 2011. Environmental samples of cotton dust were gathered with a vertical elutriator. Loss of pulmonary function was assessed based on gender and smoking status. Results: The mean number of years participants worked in the textile factory was 7.61 +/- 1.83 years, and the mean age was 35.3+5.8 years. The annual FEV1 loss of all workers was 53.2 ml, giving a ratio of annual FEV1 loss to baseline FEV1 of 1.4%. Pulmonary function parameters of all participants in 2011 were significantly lower than those in 2006 (for all, p<0.05). In both surveys, pulmonary function in current smokers was lower, but this difference was not significant (p>0.05). Conclusions: This study provides the first data on pulmonary functional loss in Turkish textile workers and supports the findings of other cohort studies that workers with long-term exposure to cotton dust may lose some pulmonary function. The ratio of annual FEV1 loss to baseline FEV1 appears to be a more accurate and comparable method than annual FEV1 loss for evaluating pulmonary functional loss.Öğe Management of spontaneous pneumothorax in patients with COVID-19(Oxford Univ Press, 2022) Ulutas, Hakki; Celik, Muhammet Reha; Gulcek, Ilham; Kalkan, Muhammed; Agar, Mehmet; Kilic, Talat; Gulcek, EmineOBJECTIVES: The coronavirus disease 2019 (COVID-19) pneumonia may cause cystic features of lung parenchyma which can resolve or progress to larger blebs. Pneumothorax was more likely in patients with neutrophilia, severe lung injury and a prolonged clinical course. The timely diagnosis and management will reduce COVID-19-associated morbidity and mortality. METHODS: We present 11 cases of spontaneous pneumothorax managed with chest tube thoracostomy or high-dose oxygen therapy. Isolated spontaneous pneumothorax was detected in all cases. RESULTS: Eight cases were male and 3 cases were female. There were bilateral ground-glass opacities or pulmonary infiltrates in the parenchyma of the 10 cases. We detected neutrophilia, lymphopaenia and increased C-reactive protein, Ferritin, lactate dehydrogenase, D-Dimer, interleukin-6 levels in almost all cases. Chest tube thoracostomy was sufficient to treat pneumothorax in our 9 of case. In 2 cases, pneumothorax healed with high-dose oxygen therapy. Favipiravir and antibiotic treatment were given to different 10 patients. In our institution, all patients with COVID-19 infection were placed on prophylactic or therapeutic anticoagulation, unless contraindicated. The treatments of patients diagnosed with secondary spontaneous pneumothorax during the pandemic period and those diagnosed with secondary spontaneous pneumothorax in the previous 3 years were compared with the durations of tube thoracostomy performed in both groups. CONCLUSIONS: The increased number of cases of pneumothorax suggests that pneumothorax may be a complication of COVID-19 infection. During medical treatment of COVID-19, pneumothorax may be the only reason for hospitalization. Although tube thoracostomy is a sufficient treatment option in most cases, clinicians should be aware of the difficulties that may arise in diagnosis and treatment.Öğe Multisystem Inflammatory Syndrome in Adults (MIS-A) Associated with SARS-CoV-2 Infection in a Young Adult Case from Turkey(Galenos Publ House, 2021) Toplu, Sibel Altunisik; Ersoy, Yasemin; Bayindir, Yasar; Kilic, Talat; Bayazit, VolkanWeeks and even months after recovering from the SARS-CoV-2 infection, clinically more severe cases are being reported, which are suggestive of COVID-19-related multisystemic inflammatory syndromes (MIS). Firstly on March 2020, this condition was reported to be COVID-19 related to children (MIS-C). Since June 2020, a syndrome similar to multisystem inflammatory syndrome in adults (MIS-A) came to be noticed in adults as well. We reported here a case of 24-year-old young woman who had gone to a hospital with abdominal pain and later developed a severe cough, followed by development of subconjunctival bleeding, pericardial effusion, pleural effusion, and intra-abdominal fluid that we deemed them to be acute multisystemic clinical symptoms, 47 days after she had undergone a COVID-19 infection of mild clinical severity. It should be kept in mind that a multisystemic inflammatory syndrome along with a delayed immune response during COVID-19 disease can be seen not only in children but also in young adults, and seemingly severe clinical and laboratory findings can improve by controlling the inflammatory process.Öğe Preventive Effect of Chrysin on Bleomycin-Induced Lung Fibrosis in Rats(Springer/Plenum Publishers, 2014) Kilic, Talat; Ciftci, Osman; Cetin, Asli; Kahraman, HasanThe aim of the current study is determination of protective effect of chrysin (CRS), a natural flavonoid, on cell injury produced by lung fibrosis induced with bleomycin (BLC) in rats. Twenty-eight female rats were assigned to four groups as follows: control group, CRS group; 50 mg/kg CRS was continued orally for 14 days, BLC group; a single intratracheal injection of BLC (2.5 mg/kg body weight in 0.25 ml phosphate buffered saline), BLC + CRS group; 50 mg/kg CRS was administered 1 day before the intratracheal BLC injection and continued for 14 days orally. All animals were sacrificed at day 14th after BLC administration. The semiquantitative assessment of histopathological consisting of lung inflammation and collagen deposition, tissue levels of thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reducted glutathione (GSH) were measured. BLC provoked histological changes consisting of alveolar congestion, increase connective tissue, infiltration, and the thickness of alveolar wall were detected significantly when compared to the control group (p a parts per thousand currency signaEuro parts per thousand 0.0001). CRS supplementation significantly restored these histological damages (p a parts per thousand currency signaEuro parts per thousand 0.0001). The level of tissue TBARS was increased with BLC (p < 0.01). Increased level of TBARS was significantly reversed by CRS administration. Also, BLC administration reduced tissue activities of SOD, GPx, CAT, and GSH in the lung tissue compared to control group (p < 0.01). Furthermore, the reduction in activities of CAT, SOD, and level of GSH were prevented by CRS supplementation (p < 0.01). In this study, we demonstrated for the first time that CRS significantly prevents BLC-induced lung inflammation and fibrosis in rats. Further studies are needed to assess the role of CRS in the treatment of lung inflammation and fibrosis.Öğe Prognostic role of simplified Pulmonary Embolism Severity Index and the European Society of Cardiology Prognostic Model in short- and long-term risk stratification in pulmonary embolism(Professional Medical Publications, 2014) Kilic, Talat; Gunen, Hakan; Gulbas, Gazi; Hacievliyagil, Suleyman Savas; Ozer, AliObjectives: Hemodynamic status, cardiac enzymes, and imaging-based risk stratification are frequently used to evaluate a pulmonary embolism (PE). This study investigated the prognostic role of a simplified Pulmonary Embolism Severity Index (sPESI) score and the European Society of Cardiology (ESC) model. Methods: The study included 50 patients from the emergency and pulmonology department of,one medical center between October 2005 and June 2006. The ability of the sPESI and ESC model to predict short-term (in-hospital) and long-term (6-month and 6-year) overall mortality was assessed, in addition to the accurancy of the sPESI and ESC model in predicting short-term adverse events, such as cardiopulmonary resuscitation, or major bleeding. Results: Of the 50 patients, the in-hospital and 6-year mortality rates were 14% and 46%, respectively. Fifteen (30%) of these experienced adverse events during hospitalization. Importantly, patients classified as low-risk according to the sPESI had no short-term adverse events as opposed to 4.8 % in the ESC low-risk group. They also had no in-hospital, 6-month, or 6-year mortality compared to 4.8%, %14.3, and %23.8, respectively, in the ESC low-risk group. Conclusions: The sPESI predicted short-term and long-term survival. The exclusion of short-term adverse events does not appear to require imaging and laboratory testing.Öğe Prognostic role of the simplified pulmonary embolism severity index and shock index in pulmonary embolism(Medycyna Praktyczna, 2014) Kilic, Talat; Ermis, Hilal; Gulbas, Gazi; Kaya, Omar; Aytemur, Zeynep A.; Inceoglu, Feyza; Hacievliyagil, Suleyman S.INTRODUCTION The stratification of acute pulmonary embolism (PE) using the simplified pulmonary embolism severity index (sPESI) and shock index (SI) does not require any prognostic tools such as biomarkers or echocardiography. OBJECTIVES We compared the ability of the sPESI and SI to predict 30-day and 3-year mortality following PE. PATIENTS AND METHODS Prognostic models based on the sPESI and SI were used to predict the overall 30-day (short-term) and 3-year (long-term) mortality in a cohort of 194 patients with confirmed PE. RESULTS Overall, the mortality rate in this cohort was 9.2% in the first month and 29.9% at 3 years. The sPESI categorized fewer patients as low risk (41.7%; 81 of 194 patients) when compared with the SI lower than 1 (74.7%; 145 of 194 patients). Importantly, patients classified as low risk in the sPESI had no 30-day mortality compared with 2.1% of patients (3 of 145) classified as low-risk based on the SI. The 3-year mortality rate in low-risk patients according to the sPESI was lower than that in low-risk patients identified based on the SI (4.9% vs. 20.7%; P < 0.0001). While a multivariate Cox analysis showed that both the SI and sPESI were independent prognostic variables for 3-year mortality, it showed that only the SI was an independent prognostic variable for 30-day mortality. CONCLUSIONS Both prognostic models allow to stratify the risk of short-and long-term mortality in patients with PE, but the sPESI was better than SI at classifying low-risk patients.Öğe Protective and Therapeutic Effect of Apocynin on Bleomycin-Induced Lung Fibrosis in Rats(Springer/Plenum Publishers, 2015) Kilic, Talat; Parlakpinar, Hakan; Taslidere, Elif; Yildiz, Sedat; Polat, Alaadin; Vardi, Nigar; Colak, CemilWe aimed to investigate the preventive and therapeutic effect of apocynin (APO) on bleomycin (BLC)-induced lung injury in rats. Rats were assigned into groups as follows: control group; APO group, 20 mg/kg APO was given intraperitoneal for 29 days; BLC-1 and BLC-2 groups, a single intratracheal injection of BLC (2.5 mg/kg); APO+BLC-preventive group, 20 mg/kg APO was administered 12 h before the intratracheal BLC injection and continued for 14 days; BLC+APO-treatment group, 20 mg/kg APO was given on the 14th day after the intratracheal BLC injection and continued to sacrifice. The BLC-1 group was sacrificed on the 14th day of BLC administration to validate BLC-induced lung inflammation and fibrosis on the 14th of study initiation. All other groups were sacrificed on the 29th day after BLC administration. The semiquantitative histopathological assessment, tissue levels of malondialdehyde (MDA), superoxide dismutase, catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), total antioxidant capacity, total oxidant status (TOS), and oxidative stress index (OSI) were measured. An addition to the serum myeloperoxidase (MPO), the cell count and cytokines (IL-1 beta, IL-6, and IL-8) of bronchoalveolar lavage (BAL) fluid were assayed. BLC-provoked histological changes were significantly detected compared to the control group. APO restored these histological damages in different quantity in the treatment and prevention groups. BLC caused a significant decrease in GSH, CAT, and GPX, which were accompanied with significantly the increased MDA, TOS levels, and OSI in the lung tissue concomitant with increased levels of the cellular account and proinflammatory cytokines in the BAL fluid. Otherwise, APO administration, both before and after BLC, reversed all biochemical markers and cytokine as well as histopathological changes induced by BLC. Interestingly, APO treatment reversed MPO activity in serum increased by BLC. In this study, both protective and therapeutic effects of APO against BLC-induced lung fibrosis were demonstrated for the first time.Öğe Protective and Therapeutic Effect of Molsidomine on Bleomycin-Induced Lung Fibrosis in Rats(Springer/Plenum Publishers, 2014) Kilic, Talat; Parlakpinar, Hakan; Polat, Alaadin; Taslidere, Elif; Vardi, Nigar; Sarihan, Ediz; Ermis, HilalWe aimed to investigate the preventive and treatment effect of molsidomine (MOL) on bleomycin (BLC)-induced lung injury in rats. Rats were assigned into groups as follows: control group; MOL group, 10 mg/kg MOL was continued orally for 29 day; BLC group, a single intratracheal injection of BLC (2.5 mg/kg), MOL+BLC-preventive group, 10 mg/kg MOL was administered 1 day before the intratracheal BLC injection and continued for 14 days; BLC+MOL-treatment group 10 mg/kg MOL was given on 14th day after the intratracheal BLC injection and continued until sacrifice. All animals were sacrificed on 29th day after BLC administration. The semiquantitative histopathological assessment, tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), total antioxidant status (TAS), total oxidant status (TOS), myeloperoxidase (MPO), and oxidative stress index (OSI) were measured. BLC-provoked histological changes were significantly detected compared to the control group. MOL restored these histological damages in different quantity in the treatment and preventive groups. BLC administration significantly decreased levels of GSH and TAS when compared to controls and these reductions was significantly ameliorated by MOL given prophylactic setting. However, therapeutic MOL administration significantly increased the TAS level decreased by BLC. The levels of MDA, MPO, and TOS were significantly increased with BLM, and these augmentations of MDA and TOS were significantly reduced by MOL given prophylactic setting. Furthermore, the OSI was higher in the BLC group, and this increase was reversed by the MOL administration before and after BLC treatment. In this study, both protective and therapeutic effects of MOL against BLC-induced lung fibrosis were demonstrated for the first time.Öğe Protective effect of dexpanthenol on bleomycin-induced pulmonary fibrosis in rats(Springer, 2013) Ermis, Hilal; Parlakpinar, Hakan; Gulbas, Gazi; Vardi, Nigar; Polat, Alaadin; Cetin, Asli; Kilic, TalatDespite extensive studies, there is no effective treatment currently available other than pirfenidone for idiopathic pulmonary fibrosis. A protective effect of pantothenic acid and its derivatives on cell damage produced by oxygen radicals has been reported, but it has not been tested in bleomycin (BLM)--induced pulmonary fibrosis in rats. Therefore, we aimed to investigate the preventive effect of dexpanthenol (Dxp) on pulmonary fibrosis. Thirty-two rats were assigned to four groups as follows: (1) control group, (2) dexpanthenol (Dxp) group; 500 mg/kg Dxp continued intraperitoneally for 14 days, (3) bleomycin (BLM) group; a single intratracheal injection of BLM (2.5 mg/kg body weight in 0.25-ml phosphate buffered saline), and (4) BLM + Dxp-treated group; 500 mg/kg Dxp was administered 1 h before the intratracheal BLM injection and continued for 14 days i.p. The histopathological grades of lung inflammation and collagen deposition, tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and myeloperoxidase (MPO) were measured. BLM provoked inflammation and collagen deposition (p < 0.0001), with a marked increase in myeloperoxidase (MPO) activity resembling increased inflammatory activity (p < 0.0001), which was prevented by Dxp (p < 0.0001, p = 0.02). BLM reduced tissue activities of SOD, GPx, and CAT compared to controls (p = 0.01, 0.03, 0.009). MDA was increased with BLM (p = 0.003). SOD (p = 0.001) and MDA (p = 0.016) levels were improved in group 4. The CAT levels in the BLM + Dxp group were close to those in the control group (p > 0.05). We showed that Dxp significantly prevents BLM-induced lung fibrosis in rats. Further studies are required to evaluate the role of Dxp in the treatment of lung fibrosis.
