TNF-α and IL-6 as biomarkers of impaired lung functions in dimethylacetamide exposure

Summary Background Tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) are well-known biomarkers of systemic inflammation that have been associated with many diseases in the past. In this study, we aimed to determine the relationship between impaired lung functions and the levels of these biomarkers in DMAc exposed people. Methods 101 non-exposed control subjects (Group 1) and 109 DMAc-exposed workers from the polyvinyl chloride (PVC) industry were included in the study. In the next step, the exposed group was divided into two groups according to the level of exposure (Group 2 and 3). DMAc, TNF-α, IL-6, creatinine, ALT, AST, GFR and standard spirometry measurements were carried out in all subjects. Results When compared to the control group, TNF-α and IL-6 levels were significantly high compatible with the increase of DMAc levels, in the exposed groups. Urinary DMAc Levels were 0.06 mg/L in the control group. This level is significantly low when compared to exposed and severely exposed group (2.43 mg/L and 3.17 mg/L). TNF-α levels were 56.86 pg/mL, 145.52 pg/mL and 230.52 pg/mL in control, exposed and severely exposed groups. IL-6 levels were found to be 38.08 pg/mL, 89.19 pg/mL and 116 pg/mL for control, exposed and severely exposed groups, respectively. Similarly, the FEV1/FVC ratio decreased especially in the severely exposed group (p 0.001). Conclusions In our study, results have revealed that TNF-and IL-6 levels are promising biomarkers in the early diagnosis of lung function impairment in inhalational DMAc exposure.

The purpose of this study was to investigate the long- and short-term inflammatory and apoptotic effects of whey protein on the livers of non-exercising rats. Thirty rats were divided into three groups namely (1) control group, (2) short-term whey (WS) protein diet (252 g/kg for 5 days), and (3) long-term whey (WL) protein diet (252 g/kg for 4 weeks). Interleukin 1β (IL-1β), IL-6, tumor necrosis factor α (TNF-α), and cytokeratin 18 (CK-18-M30) were assessed using enzyme-linked immunosorbent assay and immunohistochemical methods. Apoptosis was evaluated using the terminal transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) method. Hepatotoxicity was evaluated by quanitation of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Based on the biochemical levels and immunohistochemical results, the highest level of IL-1β was identified in the WL group ( p < 0.01). The IL-6 and TNF-α results were slightly lower in the WS group than in the control group and were highest in the WL group ( p < 0.01). The CK-18-M30 and TUNEL results were highest in the WS group and exhibited medium intensity in the WL group ( p < 0.01). AST results were statistically significant for all groups, while our ALT groups were particularly significant between the WL and control groups ( p < 0.01). The results showed that when whey protein is used in an uninformed manner and without exercising, adverse effects on the liver may occur by increasing the apoptotic signal in the short term and increasing inflammatory markers and hepatotoxicity in the long term.

Abstract Objectives The purpose of this study is to analyze the effects of rice husk liquid smoke in Porphyromonas gingivalis-induced periodontitis in the inflammatory and proliferation marker such as nuclear factor kappa β (NF-kB), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), transforming growth factor-β (TGF-β), fibroblast growth factor 2 (FGF2), collagen type 1 (COL-1) expression, and the number of macrophages, lymphocytes, and fibroblasts. Materials and Methods Rice husk liquid smoke is obtained by the pyrolysis process. Porphyromonas gingivalis-induced periodontitis in 20 μL phosphate-buffered saline containing 1 × 109 CFU was injected into the lower anterior gingival sulcus of Wistar rats. The periodontitis was then treated with 20 μL/20 g body weight of rice husk liquid smoke once a day for 2 and 7 days, respectively. After treatment, the bone and lower anterior gingival sulcus were analyzed with immunohistochemistry and hematoxylin–eosin staining. Results The treatment of periodontitis with rice husk liquid smoke showed a lower NF-kB, TNF-α, and IL-6 expression and a higher TGF-β, FGF2, and COL-1 expression than the control after treatment for 2 and 7 days (p < 0.05), respectively. The number of macrophages and fibroblasts was also higher when compared with the control group (p < 0.05), but the number of lymphocytes was lower than the control (p < 0.05). Conclusion Rice husk liquid smoke showed its effects on Porphyromonas gingivalis-induced periodontitis with a decrease in inflammatory markers and an increase in proliferation markers. The development of a rice husk liquid smoke periodontitis treatment is promising.

Abstract Background Promoter region SNPs in TNF-α have been studied in association with Recurrent Pregnancy Loss (RPL) occurrence in various populations. Among them, −238G > A, −308G > A and − 376G > A have been frequently investigated for their potential role in recurrent abortions. The aim of the present study is to evaluate the correlation among TNF-α 238, TNF-α 308 and TNF-α 376 polymorphisms and recurrent pregnancy loss risk in Greek women. Methods This study included 94 Caucasian women with at least two miscarriages of unexplained aetiology, before the 20th week of gestation. The control group consisted of 89 Caucasian women of proven fertility, with no history of pregnancy loss. DNA samples were subjected to PCR amplification using specific primers. Sanger sequencing was applied to investigate the presence of TNF-α 238, TNF-α 308, TNF-α 376 polymorphisms in all samples. Results The TNF-α 238 and TNF-α 308 variants were both detected in RPL and control groups (7.45% vs 4.49 and 45.16% vs 36.73%, respectively), but with no statistically significant association (p-value 0.396 and 0.374, respectively). The TNF-α 376 variant was not detected at all in both control and RPL groups. When TNF-α 238 and TNF-α 308 genotypes were combined no association with RPL was detected (p-value = 0.694). In subgroup analysis by parity, RPL patients carrying the A allele reported less previous births. Conclusions This is the first study demonstrating TNF-α 238 and TNF-α 308 gene expression and the absence of TNF-α 376 variant in Greek women with RPL. However, no association emerged between each polymorphism studied and the occurrence of recurrent pregnancy loss. Accordingly, TNF-α -308G > A, −238G > A and -376G > A variants are not considered genetic markers for identifying women at increased risk of recurrent pregnancy loss in the Greek population.

OBJECTIVE: To evaluate the effects of a 6 month administration of raloxifene hydrochloride, a selective estrogen receptor modulator which was recently approved for the prevention of osteoporosis, on serum gonadotropin and prolactin (PRL) levels and on TRH-stimulated PRL responsiveness in postmenopausal women who have not undergone estrogen replacement therapy. DESIGN AND METHODS: Sixteen healthy postmenopausal women were divided into two groups on the basis of their bone status, evaluated by dual energy X-ray absorptiometry at the lumbar level. Eight women (chronological age 52.4+/-4.1 (s.d.) years, menopausal age 42.4+/-3.9 years), in whom T-score L2-L4 was less than -2.5 s.d., were treated with raloxifene (60 mg p.o.) administered daily for 6 months (group 1), while the other eight women (chronological age 52.6+/-2.5 years, menopausal age 42.1+/-3.6 years), in whom the T-score L2-L4 ranged between -1 and -2.5 s.d., were used as a control group (group 2). Serum PRL, FSH, LH and 17beta-estradiol (E2) levels were evaluated at baseline and after 3 and 6 months of treatment. In all subjects, PRL responsiveness to TRH (200 microg i.v.) administration was evaluated at baseline and at the end of the study. RESULTS: At baseline, mean PRL, LH and FSH levels were not significantly different in the two groups (PRL 133.6+/-21.7 vs 136.7+/-28.1 mIU/l (NS), LH 25.1+/-6.8 vs 24.4+/-6.7 mIU/ml (NS), FSH 74.4+/-25.0 vs 71.1+/-24.1 mIU/ml (NS), in group 1 and group 2 respectively). No significant variations in serum FSH and LH values, in either group, or in serum PRL levels in group 2, were observed at the 3 and 6 month examinations. On the contrary, serum PRL values decreased significantly in group 1 after 3 months (100.1+/-47.7 mIU/l, P<0.05) and 6 months (81.5+/-30.2 mIU/l, P<0.001). At baseline, no significant differences were observed in the TRH-stimulated serum PRL peak between the groups (1015.4+/-30.5 vs 1030.2+/-25.7 mIU/l in group 1 and in group 2 respectively), while it decreased significantly at the 6 month examination in group 1 (770.5+/-47.4 mIU/l, P<0.001) and it was significantly lower than in group 2 (1068.1+/-301.8 mIU/l, P=0.02). Serum E2 was not detected at baseline and at each examination, in all patients. CONCLUSIONS: The decrease of PRL values induced by long-term raloxifene administration in postmenopausal women could be explained by a direct antiestrogenic effect of raloxifene on lactotrope cells or by the recently suggested increase of opiatergic tone on the hypothalamic-pituitary region.

BACKGROUND: Immunological mechanisms of infertility are still poorly understood and controversial, both the cause and treatment. Inflammation, immunology, cell proliferation, cell differentiation, and cell survival are influenced by several proteins, including nuclear factor kappa-B (NFĸB), tumor necrosis factor-α (TNF-α), and interleukin-10 (IL-10). AIM: This study aimed to explore the potential of nano curcumin to prevent anti-sperm antibodies (ASA) formation due to the testes’ inflammatory process in Wistar rats. METHODS: This research is an experimental study with a pre-post-test approach with control group. The research subjects were rats (Rattus norvegicus) of the Wistar strain. The induced animals were grouped into three groups: Group 1 received nano curcumin 1 × 80 mg/kg BW orally, Group 2 received dexamethasone 1 × 0.3 mg/kg BW, and Group 3 received placebo aquadest 1 × 1 mL orally. TNF-α, NF-kB, and IL10 levels in serum were examined with enzyme-linked immunosorbent assay. RESULTS: The nano curcumin treatment showed the ability to reduce the pro-inflammatory cytokine protein TNF-α expression (47.3 ± 2.32) more optimally than dexamethasone treatment (54.4 ± 3.22). Nano curcumin has also shown the ability to reduce the pro-inflammatory cytokine transcription factor, NF-kB (32.5 ± 2.76) more optimally than treatment with dexamethasone (44.6 ± 2.43). CONCLUSION: Nano curcumin can prevent the formation of ASA in testicular trauma through inhibition of the inflammatory response.

Study Objective: To study the balance in patients with vestibular bilious headache (BH) and possible use of a special comprehensive stabilometrical program for dizziness objectification in them. Study Design: open comparative study. Materials and Methods. The study included 188 patients. Group 1 were 94 patients with confirmed BH (according to the International Headache Classification). Group 2 were 94 patients with common migraine. The stabilometrical control group included 94 healthy subjects. The balance and dizziness objectification were assessed using a special comprehensive method comprising a set of stabilometrical tests. Study Results. The most marked changes in stabilometrical parameters were recorded in patients with BH. Primary frequency spectra of these patients were in a range of 0.3 Hz and above 2 Hz, showing the dysfunction of the postural system and vestibular component in particular. The rate of pressure centre deviation and statokinesigram area were increased in the patients from group 2 vs controls; however, statistically significant differences were noted only in opticokinetic test, sensory and vestibular, and closed-eye tandem results. Comparison of the two clinical groups demonstrates significant differences in basic stabilometrical parameters of all challenge tests. Visual control exclusion as well as substandard visual stimulation had significant impact on changes in the analysed parameters. Conclusion. The use of special stabilometrical tests (opticokinetic stimulation, sensory and vestibular and tandem tests) described in this article allows assessing the balance, quantifying vestibular dysfunction in patients with BH, and objectifying dizziness. Keywords: dizziness, balance, vestibular migraine, computer-aided stabilometry.

Abstract Background: We investigated bilateral tear cytokine levels including interleukin (IL)-1β, IL-10, IL-17, tumor necrosis factor (TNF)-α and Matrix metalloproteinase-9 (MMP-9) in patients with fungal keratitis(FK). Meanwhile, we evaluated the relationship between the changes of tear cytokines with corneal perception and pain in infected eyes, and the relationship between tear cytokines and tear film function in contralateral uninfected eyes .Methods : A total of 60(20 FK, 20 contralateral, 20 healthy controls) tear samples were collected prospectively and analyzed by enzyme linked immunosorbent assay(ELISA). Approximately 50 to 60 ul of tear samples in each case were collected. Meanwhile ,we analyzed the changes of visual analogue scale(VAS), tear breakup time (TBUT), Schirmer I test (SIT) and corneal perception compared with healthy controls. Results :The concentrations of IL-1β, IL-10 and IL-17 increased in bilateral eyes compared with healthy controls(P<0.05). The tear concentrations of MMP-9 , TNF-α only significantly increased in affected eyes (P <0.05). Patients with FK showed significant reduction in corneal perception of infected eyes compared with controls(P<0.05). Corneal perception of the normal eyes in FK patients was slightly lower than that of control group, but there was not statistical difference (P>0.05).TBUT and SIT of contralateral uninfected eyes were significantly lower than that of control group(P<0.05), which were significantly correlated with levels of IL-1β, IL-17(P<0.05). SIT were also negatively correlated with MMP-9(P<0.05), while the levels of IL-1β, IL-10, IL-17, TNF-α and MMP-9 in the tears of the healthy control group had no significant correlation with TBUT and SIT indicators(P>0.05).The corneal perception and VAS score of the affected FK eyes showed correlation with IL-1β, IL-17 and TNF-α(P<0.05).In addition, concentration of IL-10 inversely was correlated with VAS (P<0.05). Conclusion: Proinflammatory tear cytokines are elevated in bilateral eyes with unilateral FK as associated with tear film function ,pain and corneal sensitivity.

AbstractThe study aimed to assess: (1) differences in nutritional status and lung function between CF patients and the control group; (2) differences in body composition and lung function between groups of patients with CF designated by type of mutation; (3) the relationship between lung function and body composition in CF patients.We studied 37 CF patients aged 19 to 51 years, and 41 healthy non-CF volunteers. Nutritional status was evaluated based on the BMI and the bioelectrical impedance analysis. The lung function was described by FEV1%. CF patients were classified according to the CFTR genotype based on five classes of mutations. BMI were lower in CF patients compared to reference group (women: Z = 3.76, p <0.001, men: Z = 3.06, p = 0.002). CF patients had a lower mean content of particular body components, as well as FEV1% values. BMI differed significantly depending on the type of mutation in females (H = 10.33, p = 0.006) and males (H = 8.26, p = 0.016). The lowest values of BMI were observed in the group of patients with severe types of mutations. Also, variables describing body composition were statistically significantly lower in patients with a severe type of mutations. The CFTR gene mutation type statistically significantly differentiated FEV1% (H = 23.22, p <0.000). The results of the logistic regression analysis showed that the likelihood of dropping FEV1% below the norm was twice as high in undernourished females and males. To assess the nutritional status of CF patients, more informative methods describing the proportions of body components are required.

Tuberculosis(TB) is aninfectious disease caused by Mycobacterium tuberculosis. The aim was to investigate the levels of immunomodulatory markers like interluekin-6 (IL-6), tumor necrotizing factor-α (TNF- α),cell differentiation-4 (CD4) and CD8 levels in those patients with active tuberculosis (TB) disease in comparison with control group. 41 Adults diagnosed with TB were included in comparison to 32 healthy individuals at Babylon health center for pulmonary diseases and TB. Descriptive data for patients and control group werecollected by well-trained researcher following a structured questionnaire. In parallel, peripheral blood collected to determine IL-6, TNF- α,CD4 and CD8. Then the assessment for the association between clinical and descriptive data and immunomodulatory markers levels was investigated statistically. The majority of TB patients were males (56%) and 71% were resident in rural areas; 47% of them were living in middle socioeconomic state,moreover,47% of TB cases had diabetes,furthermore,51% had chronic obstructive pulmonary diseases,12% had hypertension and 39% of them had chronic anemia with 47% smokers with no significant difference versus control. Following to that,there was highly increased in IL-6 and TNF-α levels in TB patients versus control (P<0.001),with low CD4 level versus control (P<0.001). While there was no significant change shown in CD8 levels versus control and this might highly be correlated with 30% of abnormal liver function tests among TB patients. A high proportion of TB patients have low CD4 level mostly associated with active disease. Moreover,the increase of IL-6 and TNF-α levels suggests a inverse impact on CD4 level which closely associated with the outcome of the disease.

Objective. To investigate the expression and prognostic value of LncRNA FAF in patients with coronary heart disease. Patients and Methods. 97 patients with coronary heart disease who came to our hospital were selected as the research group (RG), and 97 healthy people who came to our hospital for physical examination during the same period were selected as the control group (CG). The serum LncRNA FAF, plasma homocysteine (HCY), lipoprotein A (Lp-a), serum tumor necrosis factor α (TNF-α), and high-sensitivity C-reactive protein (hsCRP) in the two groups of patients were detected, and their correlations were analyzed. Then, the predictive value and risk factors of FAF for poor prognosis of patients with coronary heart disease were analyzed. Results. The expression of LncRNA FAF in the serum of patients in the RG was significantly lower than that in the CG, and the expressions of HCY, Lp-a, TNF-α, and hsCRP were significantly higher than those in the CG (p <0.05). The AUC of FAF in the diagnosis of coronary heart disease was more than 0.9. FAF was negatively correlated with the coronary lesion vessels, HCY, Lp-a, TNF-α, and hsCRP expressions in patients with coronary heart disease ( p < 0.05 ). The ROC of FAF for predicting poor prognosis in patients with coronary heart disease was greater than 0.9. Low expression of FAF; high expressions of HCY, Lp-a, and hsCRP; and increase of coronary lesion vessels were independent risk factors for poor prognosis in patients with coronary heart disease. Conclusions. LncRNA FAF was lowly expressed in the serum of patients with coronary heart disease, and it was of high value in the diagnosis and prediction of poor prognosis of coronary heart disease. It was also an independent risk factor for poor prognosis of patients with coronary heart disease and may be a potential target for diagnosis and treatment of coronary heart disease.
