BackgroundTuberculosis is a disease that can involve every organ system. While pulmonary tuberculosis is the most common presentation, extrapulmonary tuberculosis (EPT) is also an important clinical problem. The current study aimed to outline and compare the demographic and clinical features of pulmonary and extrapulmonary tuberculosis cases in adults.MethodsMedical records of 411 patients (190 women, 221 men) treated between January 2010 and July 2014 in provincial tuberculosis control dispensary was retrospectively reviewed. Demographic and clinical characteristics were compared for pulmonary and extrapulmonary tuberculosis cases.ResultsOf these 411 cases, 208 (50.6 %) had pulmonary tuberculosis (PTB) and 203 were diagnosed with extrapulmonary tuberculosis (EPTB) (49.4 %). The average ages for PTB and EPTB groups were 33.00-27.00 and 31.00-29.75, respectively (p = 0.513). Men were more frequently affected by PTB (59.6 %), while EPTB was more commonly detected in women (52.2 %) (p = 0.016). Main diagnostic modalities for PTB were sputum/smear analyses (72.7 %), clinical-radiological data (21.7 %) and biopsy (6.1 %); while biopsy (71.5 %), sputum/fluid analysis (18.8 %) and clinical-radiological data (4.9 %) were used for confirming EPTB (p < 0.0019). The most common sites of EPTB involvement were lymph nodes (39.4 %), followed by pleura (23.6 %), peritoneum (9.9 %) and bone (7.4 %).ConclusıonsExtrapulmonary involvement of tuberculosis is common and females are more likely to be affected. Increased clinical awareness is important since atypical presentations of the disease may constitute diagnostic and therapeutic challenges.
Background: The hepatitis B virus is a significant pathogen that causes cirrhosis, and hepatocellular cancer as a result of the damage it causes to liver cells. Its infection affects more than 400 million people globally. Although there is an effective vaccine and treatment methods, almost 1, 000, 000 people die every year. Objective: To investigate paraoxonase and arylesterase activities along with oxidative status parameters and serum lipid levels, and to find out if there is any increased susceptibility to atherogenesis. Methods: Thirty-four subjects with chronic hepatitis B and 39 healthy subjects as control were enrolled in the study. Age, body mass index and gender, Serum Triglycerides (TG), High-density Lipoprotein (HDL) and Low-Density lipoprotein (LDL) levels, serum paraoxonase-1 and arylesterase activities were determined. Oxidative and antioxidative statuses were evaluated by measuring serum-free sulfhydryl groups, lipid hydroperoxide levels, total antioxidant capacity, total oxidant status, and oxidative stress index. Results: Serum TG and LDL levels were higher while serum HDL levels were lower in patients with chronic hepatitis B than in controls but the differences did not reach statistical significance. Serum paraoxonase-1 and arylesterase activities, plasma free sulfhydryl groups, and total antioxidant capacity were significantly lower in patients than in controls (p=0.018, p=0.005, p<0.001, p=0.037 respectively), while lipid hydroperoxide, total oxidant status, and oxidative stress index were significantly higher (for all p<0.001). Conclusion:The diminution in the paraoxonase-1 and arylesterase activities could contribute to the accelerated development of atherosclerosis in patients with chronic hepatitis B.
To conclude, our results suggest that suPAR can be a useful diagnostic biomarker in patients with VAP. However, clinical trials on larger series are warranted to explore the clinical significance more accurately.
Objectives: COVID-19 is an important viral disease that affects human health significantly. It has recently become widespread worldwide. The oxidant/antioxidant balance has an important effect on viral infections. This study investigated superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione (GSH), total thiol (TT), native thiol (NT), disulphide (DS), oxidative DNA damage, and malondialdehyde (MDA) levels in COVID-19 patients. Material and methods: 35 patients were diagnosed with COVID-19 by reverse transcriptase-polymerase chain reaction (RT-PCR), and 35 healthy volunteers at Dursun Odabaş Medical Center were included in the study. Levels of GSH, GPx, SOD, NT, TT and DS were measured by enzyme-linked immunosorbent assay (ELISA) in the serum samples. MDA and 8-hydroxy-2-deoxyguanosine/106deoxyguanosine (8-OHdG/106dG) were measured by high-pressure liquid chromatography (HPLC) in the serum samples. Results: SOD, GSH-PX, GSH, NT and TT levels were lower in the COVID-19 patient group compared to the healthy control group, while the levels of DS and 8-OHdG/106dG were significantly higher (p=0.001). In addition, there were a negative correlation between 8-OHdG/106dG and GSH, NT and TT, while there was a positive correlation with DS. Conclusion: This study revealed that SOD, GPX, MDA, 8-OHdG, and DS increased and GSH, NT, and TT decreased in COVID-19 patients. These results revealed that COVID-19 patients have reduced levels of antioxidant proteins and increased oxidative stress markers.
Background: Objectives: The main aim of this study was to compare, by a new automated colorimetric method, oxidant and anti-oxidant status of those who fast during Ramadan and those who do not. For this purpose, total oxidant status (TOS), total anti-oxidant capacity (TAC) levels and oxidative stress index (OSI) were analysed. By doing this, we hope to examine whether fasting has any beneficial effect on human health.Materials and methods: Fifty seven people were included in this study. Of these, 30 people had been fasting during the month of Ramadan for at least ten years, but 27 had never fasted in their life. On the 15th day of Ramadan, blood samples were obtained from both groups after 12 hours of fasting. Results: The TAC levels of the fasting group (1.29±0,19) was quite higher than the non-fasting group (1,09±0,16) [EIC2][ICD3][ICD4](p< 0.001). Similarly, in the fasting group TOS level and the OSI (respectively 12,77±2,23 and 1,01±0,25) was quite lower [EIC5][ICD6][ICD7] than in the non-fasting group (respectively 14,15±2,04 and 1,33±0,30), (p<=0.019 and p<0.001, respectively).These findings show that the TOS level of non-fasting group was high. This oxidative stress might cause various illnesses. Therefore, fasting could play a significant part in health-protection by increasing total anti-oxidant capacity.Keywords: Fasting Ramadan, oxidative parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
