Assessment of the role of albuminuria and uromodulin in the early diagnosis of renal function disorders in some types of obesity phenotypes

The aim: to study of the relationship of biological markers reflecting damage of the kidneys with its functional state, as well as with clinical, metabolic, hormonal parameters and immunoinflammatory processes in obesity phenotypes.Patients and Methods: The study involved 224 obese Uzbek women who were divided into 2 groups according to the recommended criteria for metabolic syndrome: group 1 consisted of 133 women diagnosed with metabolic complicated obesity, average age 42.0±0.5; Group 2 consisted of 91 women diagnosed with metabolic healthy obesity, average age 41.7±0.7. The control group consisted of 45 healthy volunteers (women, mean age 43.2±0.8, body mass index ˂ 30 kg/m2, waist circumference less than 80 cm). In the observation groups, anthropometric indicators, blood pressure, biochemical tests and blood lipid spectrum, levels of leptin, insulin, cystatin C and uromodulin in the blood serum, gradations of microalbuminuria in urine were determined, the glomerular filtration rate was calculated for cystatin C and creatinine and the obtained indicators were compared.Results. In both obesity phenotypes, the amount of microalbuminuria and cystatin C significantly increased in group 1 compared to these indicators in group 2 and the control group, and the amount of uromodulin in the blood serum, on the contrary, decreased compared to the indicators in group 2 and control group (r ˂ 0.001) . An increase in the gradation of microalbuminuria and cystatin C and a decrease in the amount of uromodulin in the blood serum in both groups was expressed by a decrease in the estimated glomerular filtration rate, which was clearly expressed in group 1 (χ2 = 4.5, r = 0.034). Also, an increase in body mass index was characterized by an increase in cardiometabolic disorders, an increase in the gradation of microalbuminuria, a decrease in the level of uromodulin in the blood serum and cytokinemia (p ˂ 0.001).Conclusion. In both obesity phenotypes, an increase in the degree of obesity was manifested by an increase in the level of cardiometabolic risk, as well as an increase in subclinical kidney damage. It is considered appropriate to determine the amount of uromodulin and cystatin C in blood serum and assess the gradation of microalbuminuria in the early diagnosis of renal dysfunction in obesity.

The Level of Leptin in the Blood of Patients with Chronic Obstructive Pulmonary Disease and its Correlations with the Levels of Clinical, Functional and Anamnestic Indicators

Leptin, a hormone produced by white adipose tissue and recognised as an inflammatory biomarker, has an undefined role in the progression of chronic obstructive pulmonary disease (COPD). Objective — to evaluate the leptin level and its correlations with the levels of clinical, functional and anamnestic indicators in COPD patients. Materials and methods. This study employed a case-control design involving 42 patients experiencing acute exacerbation of COPD and 20 control subjects. The patients were examined according to the standard protocol. Additionally, the examination included ultrasonic scanning of the abdominal cavity, evaluation of the serum leptin level, scoring of the anxiety and depression and quality of life. Results and discussion. It was revealed that hyperleptinemia in the patients with acute exacerbation of COPD occurred significantly more frequently than in the healthy persons ((73.8 ± 6.8) vs (40.0 ± 11.0) %; р < 0.05). Besides, the COPD patients manifested increased leptin levels much more frequently than normal levels ((73.8 ± 6.8) vs (26.2 ± 6.8) %; р < 0.01). Hyperleptinemia was found to co-occur with severe COPD cases belonging to E clinical group ((51.6 ± 9.0) vs (18.2 ± 11.6) % in group with normal leptin level; р < 0.05). Kendall correlation analysis established that elevated circulating leptin levels were associated with an increased body mass index (τ = 0.3; р = 0.02), female gender (τ = 0.3; р = 0.01), non-smoking history (τ = – 0.2; р = 0.03), stronger manifestation of such symptoms as shortness of breath (τ = 0.3; р=0.01), disturbed home (τ = 0.3; р = 0.002) and out-of-home activities (τ = 0.3; р = 0.02) and lack of energy (τ = 0.3; р = 0.01). It also correlated with increased severity of pulmonary insufficiency (τ = 0.3; р = 0.003) and decreased forced vital capacity (τ = – 0.2; р = 0.04), elevated systolic blood pressure (τ = 0.2; р = 0.02), elevated cholesterol (τ = 0.3; р = 0.01) and β-lipoproteins levels (τ = 0.2; р = 0.04), pronounced depression (τ = 0.3; р = 0.002) and lowered quality of life (τ = 0.3; р = 0.01). Сonclusions. COPD patients with elevated leptin levels manifest not only with an increased body weight, but also with arterial hypertension, disturbed lipid metabolism, more pronounced pulmonary insufficiency, depressive disorders and lowered life quality with more severe subjective respiratory symptoms.

Leptin, Nesfatin-1, Orexin-A, and Total Ghrelin Levels in Drug-Naive Panic Disorder.

This study aimed to examine the changes in serum nesfatin-1, leptin, orexin-A, and total ghrelin levels of patients diagnosed with drug-naive panic disorder (PD) before and after six weeks of the treatment and to compare the findings with the healthy subjects. The neuropeptides were measured in venous blood samples taken from 32 patients and 32 healthy subjects. The blood samples of the patients who used paroxetine 20 mg/day plus alprazolam 0.5 mg/day were retaken again after six weeks. Measurements were performed with the Enzyme-Linked Immunosorbent Assay (ELISA) method. Serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were found to be significantly lower than the control group (p<0.001, p<0.001, p<0.001, and p<0.001, respectively). When the serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were compared before and after treatment, significant differences were found in terms of orexin-A and total ghrelin levels (p=0.046, p<0.001, respectively). However, no significant differences were found in terms of nesfatin-1and leptin levels (p=0.205, p=0.988, respectively). This study reports that PD, like other anxiety disorders, may affect serum nesfatin-1, leptin, orexin-A, and total ghrelin levels, and there may be a relationship between PD treatment and the levels of these neuropeptides. The variability of this relationship among the neuropeptides examined indicates that various factors other than treatment play a role in this process.

Serum Leptin levels in newly diagnosed Epileptic Patients.

To compare leptin levels in newly-diagnosed treatment-naive epileptic patients and healthy controls. This case-control study was conducted from January 10 to September 15, 2022, at the Dow University of Health Sciences, Karachi, and comprised newly-diagnosed epileptic patients age 12-35years who had no comorbidity. The subjects were enrolled from the Neurology out-patient department of Civil Hospital, Karachi. Healthy individuals matched for age, gender and body mass index were also enrolled as controls. Blood samples were collected between 8am and 10am for the evaluation of serum leptin levels using enzyme-linked immunosorbent assay. Data was analysed using SPSS 26. Of the 100 subjects, 64(64%) were males and 36(36%) were females. There were 50(50%) cases with mean age 19.34±5.65 years, and 50(50%) controls with mean age 19.76±5.67 (p=0.614). 100% of 50 individuals in control group did not have any family history of epilepsy,while 18% of cases (9) reported a positive family history. Mean leptin level in cases was 31.03±19.37 compared to 5.25±4.03 in the controls (p<0.05). Serum leptin levels were elevated in newly-diagnosed epileptic patients compared to healthy controls.

Sex-Specific Effects of Long-Term Antipsychotic Drug Treatment on Adipocyte Tissue and the Crosstalk to Liver and Brain in Rats.

Antipsychotic drug (APD) medication can lead to metabolic dysfunctions and weight gain, which together increase morbidity and mortality. Metabolically active visceral adipose tissue (VAT) in particular plays a crucial role in the etiopathology of these metabolic dysregulations. Here, we studied the effect of 12 weeks of drug medication by daily oral feeding of clozapine and haloperidol on the perirenal fat tissue as part of VAT of male and female Sprague Dawley rats in the context of complex former investigations on brain, liver, and blood. Adipocyte area values were determined, as well as triglycerides, non-esterified fatty acids (NEFAs), glucose, glycogen, lactate, malondialdehyde equivalents, ferric iron and protein levels of Perilipin-A, hormone-sensitive-lipase (HSL), hepcidin, glucose transporter-4 (Glut-4) and insulin receptor-ß (IR-ß). We found increased adipocyte mass in males, with slightly higher adipocyte area values in both males and females under clozapine treatment. Triglycerides, NEFAs, glucose and oxidative stress in the medicated groups were unchanged or slightly decreased. In contrast to controls and haloperidol-medicated rats, perirenal adipocyte mass and serum leptin levels were not correlated under clozapine. Protein expressions of perilipin-A, Glut-4 and HSL were decreased under clozapine treatment. IR-ß expression changed sex-specifically in the clozapine-medicated groups associated with higher hepcidin levels in the perirenal adipose tissue of clozapine-treated females. Taken together, clozapine and haloperidol had a smaller effect than expected on perirenal adipose tissue. The perirenal adipose tissue shows only weak changes in lipid and glucose metabolism. The main changes can be seen in the proteins examined, and probably in their effect on liver metabolism.

Progesterone treatment reduces food intake and body weight in ovariectomized female rats

While the effects of progesterone on body weight and appetite in pre-menopausal conditions have been well elucidated, its effects in post-menopausal conditions have not been clarified. On the contrary, the effects of estrogen on body weight and appetite in post-menopausal conditions have been well established. In this study, the effects of progesterone treatment on body weight, appetite, and fat mass in ovariectomized rats were evaluated. In addition, the central and/or peripheral levels of oxytocin (OT), leptin, and their receptors, which are potent anorectic factors, were examined. Female rats were ovariectomized and divided into control, progesterone-treated, and estrogen-treated groups. Body weight, food intake, and subcutaneous fat mass were lower in both the progesterone and estrogen groups than in the control group. The estrogen group exhibited higher serum OT levels than the control group, whereas the OT levels of the progesterone and control groups did not differ. The serum leptin levels of both the progesterone and estrogen groups were lower than those of the control group. Gene expression analysis of OT, leptin, and their receptors in the hypothalamus and adipose tissue found few significant differences among the groups. Hypothalamic neuropeptide Y (NPY) and pro-opiomelanocortin (POMC) mRNA levels involved in appetite regulation were slightly altered in the progesterone and estrogen groups. These findings suggest that progesterone treatment may have favorable effects on body weight, appetite, and fat mass regulation in post-menopausal conditions and that the mechanisms underlying these effects of progesterone differ from those underlying the effects of estrogen.

Adipocytokines levels as potential biomarkers for discriminating patients with a diagnosis of depressive disorder from healthy controls

BackgroundDepressive disorder is a complex mental health condition in which the etiopathogenesis involves several factors. Suitable biomarkers for the development of depression have not yet been established. Alterations in cytokines are assumed to be involved in the pathophysiology of depressive disorder. Adipokines (also known as adipocytokines) are important factors that not only regulate the energy balance but also regulate the inflammatory and immune responses. This study investigated the serum levels of adiponectin, leptin, resistin, chemerin, and fetuin A and the possible role of these adipokines in depressive disorder. MethodsWe recruited a total of 73 patients diagnosed with recurrent depressive disorder (rDD) and 54 age- and sex-matched healthy controls (HCs). Serum adipocytokines were determined using ELISA kits (R&D, USA). The serum levels of the investigated molecules between depressive patients and HCs were compared, and diagnostic values were evaluated using the receiver operating characteristic (ROC) curve method for discriminating depressive patients from HCs. Correlations between the molecules and clinical variables were also evaluated. ResultsPatients with rDD had lower levels of serum adiponectin and chemerin and higher levels of serum leptin, resistin and fetuin A (p < 0.05) vs. controls. Moreover, ROC curve analysis showed that the area under the curve (AUC) values of above set of adipocytkines were >0.7, with a sensitivity and specificity over 80% in discriminating patients with rDD from HCs. Conclusions: These results suggest that circulating adipocytokies may hold promise as biomarkers for the diagnosis of rDD.

O-09 A rare cause of acute pancreatitis: Werner Syndrome

Abstract Introduction Lipodystrophies are rare disorders characterized by loss of body fat resulting in leptin deficiency. Patients are predisposed to metabolic complications such as severe insulin resistance, hypertriglyceridemia, and hepatic steatosis. Werner syndrome (WS) is among the progeroid syndromes in the classification of lipodystrophy. Due to its extremely rare occurrence, it can often be overlooked by the clinician. Clinical Case A 19 years old male patient hospitalized for non-biliary acute pancreatitis was consulted for hypertriglyceridemia and hyperglycemia. He had no history of any disease or medication use. His sister was diagnosed with type 2 diabetes mellitus at age 29. She was using linagliptin and gliclazide for 3 years. She had short stature (147 cm) and low body weight (40 kg) and had scleroderma-like skin findings. The patient also had short stature (157 cm) and low body weight (41 kg). He had scleroderma-like skin findings and generalized loss of subcutaneous adipose tissue. The laboratory results were; glucose, 261 mg/dl; creatinine, 0.46 mg/dl; ALT, 24 U/l; lipase, 161 U/l; HbA1c, 9.6%; triglyceride, 799 mg/dl; HDL, 9.6 mg/dl; LDL, 75 mg/dl; c-peptide, 4.3 ng/dl. The thyroid function test results (TSH: 29.7 µIU/ml, fT4: 6.81 pmol/L, Anti-TPO: negative) were consistent with primary hypothyroidism. Hepatosteatosis was observed in abdominal ultrasonography. We initiated intensive insulin, metformin as well as fenofibrate and levothyroxine treatment. The patient needed high insulin doses (60 IU/day). Measured serum leptin levels were found to be low (2.11 ng/ml) in suspicion of lipodystrophy. Genetic analysis of the patient and his sister showed homozygous mutation in the WRN gene (c.1105C&amp;gt;T p.Arg369Ter, Homozygous) which was compatible with WS. The patient was started on leptin analog therapy in a clinical trial. Conclusion WS is an exceptionally rare autosomal recessive genetic disorder characterized by premature aging and multisystemic complications. The clinical features encompass scleroderma-like skin changes, short stature, low body weight, alopecia, cataracts, osteoporosis, and a propensity for atherosclerotic complications and malignancies. Impaired glucose tolerance is reported in 15%–20% of WS subjects, diabetes mellitus in 55%–70%, and dyslipidemia in 60%–85%. The presence of hypertriglyceridemia, diabetes mellıtus and generalized lack of subcutaneous adipose tissue led us to suspect from lipodystrophy. Although acute pancreatitis due to hypertriglyceridemia can be seen in lipodystrophy (15-20%), first presentation of WS presenting with acute pancreatitis is very rare in the literature. The most common mutation in non-Japanese patients in WRN gene is c.1105 C&amp;gt;T (18.6%). Metreleptin, an analog of human leptin, is shown to ameliorate the metabolic derangements. WS remains a diagnostic challenge due to its rarity, atypical presentation, and should be kept in mind in patients with severe dyslipidemia and insulin resistance.

A crossover randomized controlled trial examining the effects of black seed (Nigella sativa) supplementation on IL-1β, IL-6 and leptin, and insulin parameters in overweight and obese women

BackgroundNigella sativa (NS) oil has been found to have advantageous benefits in the management of inflammation and obesity. This study investigated the effect of NS supplementation on blood mRNA expressions and serum levels of IL-1β, IL-6, leptin, and insulin concentrations in overweight/obese women.MethodsIn a crossover design, participants were randomized to receive either NS supplements(2000 mg/day) or placebo for 2 durations(8 weeks). With between-subject and within-subject components and interactions, a repeated-measure ANOVA model was used considering the treatment, time, and the carryover effects. Cohen’s d(d) was used to measure the magnitude of the effects.ResultsForty-six eligible participants were included. NS supplementation significantly reduced the mRNA expressions(d=-0.68, P = 0.03) and serum levels of IL-1β with medium-high effect sizes(d=-1.6, P < 0.001). Significant reductions with large effect sizes were observed in the gene expression and serum levels of IL-6(d=-1.8, d=-0.78, respectively; P < 0.01) and Leptin(d=-1.9, d=-0.89, respectively; P < 0.01, serum leptin P carryover < 0.001). Despite the meaningful carryover effect for serum leptin, results remained significant following the first intervention period analysis(P < 0.001). A significant but low effect size decrease in serum insulin was observed(d=-0.3, P = 0.02).ConclusionsThe clinical significance of present findings regarding improvements in obesity-related pro-inflammatory markers must be interpreted with caution due to some observed medium-low effect sizes.Trial registrationIRCT20180430039475N1 (Date:25/6/2018).

Serum Adipokines as Biomarkers for Surveillance of Metabolic Syndrome in Childhood Acute Lymphoblastic Leukemia Survivors in Low Middle-Income Countries

Background Serum adipokines (leptin and adiponectin) are dysregulated before the onset of metabolic syndrome and hence may be useful biomarkers for screening of cardiometabolic late effects in childhood Acute Lymphoblastic Leukemia (cALL) survivors. Methods We compared serum adipokine levels between 40 cALL survivors (aged 10–18 years, >2 years from treatment completion) with similar controls. A multivariable logistic regression analysis was then done to assess the association of metabolic syndrome in cALL survivors with variables including adipokines and other metabolic parameters, demographic and treatment details, and Dual-energy X-ray absorptiometry scan-derived variables. Results Compared to controls, cALL survivors had a higher prevalence of metabolic syndrome (8/40 vs. 2/40, P = .044) and central obesity (11/40 vs. 4/40, P = 0.042). Median Serum Leptin (7.39 vs. 4.23 ng/ml, P = 0.207) levels and derived Leptin-Adiponectin Ratio (1.44 vs. 0.80, P = 0.598), were higher but not statistically different in our survivors compared to controls; Adiponectin levels were similar (6.07 vs. 5.01 µg/ml, P = 0.283). In the cALL survivors, overweight/obesity (odds ratio [OR] 21.9, P = 0.020) or higher Leptin levels (OR 1.11, P = 0.047), were independently associated with metabolic syndrome. Conclusions Serum Leptin, independently predictive of metabolic syndrome in our cALL survivors, may be tested in larger studies to assess its utility in surveillance and initiation of early preventive measures.

Platelet and white blood cell counts correlate with leptin and body mass index in Japanese adolescents.

Obesity is associated with mild chronic inflammation, frequently observed along with increased platelet and white blood cell (WBC) levels in adults. We aimed to clarify the relationship between peripheral blood cell count, body mass index standard deviation score (BMI-SDS), and adipocytokine levels in obese adolescents. Participants included 31 patients with obesity (age: 13.1 ± 3.1 yr) and 28 normal-weight controls (age: 13.3 ± 1.9 yr). Obesity was defined as a percentage of overweight ≥ 20%; patients with type 2 diabetes were excluded. As sex differences were observed in blood cell counts, the analysis was performed after adjusting for sex differences. The obese group has significantly higher WBC, red blood cell, and platelet counts, as well as high serum leptin levels and Homeostasis Model Assessment of insulin resistance (HOMA-IR) scores compared with those of the control group. In all participants, BMI-SDS significantly correlated with WBC and platelet counts. Platelet count correlated with serum leptin and glucose levels, whereas WBC count correlated with serum leptin, insulin, HOMA-IR, and glucose levels. Statistical analysis showed that serum leptin level significantly influenced the platelet count and HOMA-IR score affected WBC count. Increased platelet and WBC counts in adolescents with obesity may increase the risk of thrombosis.

Comparison of endogenous hypothalamic and serum OT levels between young and middle-aged perimenopausal female rats.

Oxytocin (OT) regulates food intake and body weight, particularly in obese individuals. Decreases in the effects of OT have recently been implicated in metabolic disturbances, and the administration of estradiol (E2) increased serum OT levels. Although weight gain is frequently observed in perimenopausal women, endogenous OT levels remain unclear. Therefore, we herein compared endogenous levels of hypothalamic and serum OT between young and middle-aged perimenopausal female rats and examined the relationship between serum estrogen and leptin levels. Body weight and visceral and subcutaneous fat weights were higher in middle-aged rats. Although no significant differences were observed in serum OT and E2 levels, serum leptin levels and hypothalamic mRNA levels of OT and the OT receptor (OTR) were significantly higher in middle-aged rats than in young rats. Serum OT levels did not correlate with hypothalamic OT mRNA levels or serum E2 levels. E2 maintains serum OT levels in perimenopausal rats, and other factors may elevate hypothalamic OT/OTR mRNA levels. Increases in body and fat weights in perimenopausal rats may be attributed to factors other than OT. Therefore, the administration of OT alone may not be sufficient to prevent metabolic disorders induced by the perimenopausal status. J. Med. Invest. 71 : 246-250, August, 2024.

Leptin as a predictive marker for lymph node metastasis in patients with papillary thyroid cancer

Background Leptin is a neuroendocrine hormone produced from adipose tissue with many vital functions. There is a well-known association between leptin and papillary thyroid cancer (PTC). Preoperative prediction of lymph node metastasis is one of the interesting topics in PTC. This study aimed to determine whether the serum leptin peptide is a significant predictor marker for node metastasis in cases with PTC. Patients and methods This is a prospective comparative study which was conducted at Ain Shams University Hospitals and El-Sheikh Zayed specialized hospital between January 2021 and January 2023. Forty patients with PTC were enrolled in this study and according to postoperative histopathology, we divided them into two groups: group A, 24 cases, those with pathological negative node and group B, 16 cases, those with pathological positive node. Results We had no statistically significant difference in the preoperative demographics data between both groups. Postoperatively, the median serum leptin level and percentage of leptin decrease were significantly higher in in group B. Multivariate logistic regression analysis showed that preoperative serum leptin level, thyroid imaging reporting and data system, multifocality, extra thyroid extension, and size of dominant nodule were significant predictors for node metastasis. There was a significant negative correlation between leptin level and age, while there was a significant positive correlation between leptin level and lymph node metastasis. Conclusion Preoperative serum leptin level is considered a significant predictor marker for lymph node metastasis in PTC.

Adipocytokines and Inflammation in Patients and a Gerbil Model: Implications for Obesity-Related and Nonobese Diabetes.

Background: Obesity is a predisposing risk factor for type 2 diabetes mellitus (T2DM). Actually, not only obese/overweight but also nonobese/lean individuals may be prone to T2DM. This study is aimed at identifying the contribution of adipose tissue to the development of nonobese diabetes (NOD) and obese diabetes (OD). Methods: Serum samples from the nonobese nondiabetes (NOND, n = 47, age = 46.8 ± 8.4, BMI ≤ 23.9 kg/m2) controls, NOD (n = 48, age = 50.7 ± 6.5, BMI ≤ 23.9 kg/m2) and OD (n = 65, age = 49.8 ± 10.2, BMI ≥ 28 kg/m2) patients were utilized to measure the expression of metabolic indicators, adipocytokines, inflammatory factors. Different adipose depots from offspring with corresponding blood glucose and obesity levels of a spontaneously diabetic gerbil line with various degrees of diabetic penetrance and body weights were examined for adipocytokines and inflammation factors detected by ELISA and western blot. Adipose tissue volume and fat cell size of the gerbils were evaluated by magnetic resonance imaging and immunohistochemistry, respectively. Results: The study yielded four key findings. Firstly, in comparison to the NOD group, the OD group exhibited more severe insulin resistance (IR) and metabolic dysfunction in both patients and gerbils, attributed to higher visceral adipose tissue mass and larger fat cell sizes. Secondly, in gerbils, gonadal fat deposition was linked to obesity development, whereas kidney fat deposition correlated with obesity and diabetes occurrence. Thirdly, in both patients and gerbils, the interplay between adiponectin and leptin levels in serum may significantly influence the development of obesity and diabetes. Lastly, heightened expression of MCP3 in gerbils' kidney adipose tissue may serve as a pivotal factor in initiating obesity-associated diabetes. Conclusions: Our study, which may be considered a pilot investigation, suggests that the interaction of adipocytokines and inflammation factors in different adipose depots could play diverse roles in the development of diabetes or obesity.

Evaluation of serum levels of leptin and ghrelin in patients with celiac disease before and after treatment with a gluten-free diet

Background and Objective. Celiac disease (CeD) is an autoimmune condition characterized by specific serological and tissue characteristics resulting from gluten consumption in genetically predisposed individuals. The only currently treatment available for CeD is strict lifelong adherence to a gluten-free diet (GFD), which leads to remission. This study aimed to evaluate leptin and ghrelin serum levels in celiac patients before and after treatment with a gluten-free diet. Patients and Methods. Thirty patients aged 3 to 50 years with CeD and 30 age- and gender-matched healthy controls were included in the study. Serum levels of leptin and ghrelin in patients before GFD and after four months of GFD treatment were measured using ELISA kits. Results. The mean serum ghrelin concentration in celiac cases decreased from 653.6 pg/ml to 483.2 pg/ml after GFD treatment (p &lt; 0.001). Although the mean serum ghrelin concentration before treatment was not significantly different between the case and control groups, it was significantly lower in celiac patients than in the control group after treatment (p &lt; 0.001). The average concentration of serum leptin in the control group was significantly higher than before and after the treatment of celiac patients, but the average concentration of serum leptin in celiac patients did not change significantly after GFD treatment (p = 0.298). Conclusion. In conclusion, this study suggests that a GFD can positively affect the levels of leptin and ghrelin hormones in celiac patients. Key words: celiac disease, leptin, ghrelin, gluten-free diet

Background: The cardiovascular diseases are phenomenon or circumstances that affect the structures as well as function of the heart. Aim: The level of glucocorticosteroids, thyroid hormones, leptin, and endothelins in cardiovascular subjects was determined in Owerri, Imo state. Method: A total of 100 subjects within the age 35-65 years were recruited for this study. The study consists of 50 subjects who were diagnosed of cardiac disorders and 50 were apparently healthy individuals who served as controls subjects of the same age bracket. The levels of glucocorticosteroids, thyroid hormones, leptin, and endothelins were analysed using ELISA technique. Data was assessed using SPSS version 20, the mean value with P˂ 0.05 was considered statistically significant. Results: The result revealed that the levels of glucocorticosteroids, thyroid hormones, leptin, and endothelins in cardiovascular disorder were significantly increased when compared with control subjects. Conclusion: The increased serum level of glucocorticosteroids, thyroid hormones, leptin, and endothelins in cardiac malfunction subjects may contribute some risk factors in patients with cardiac dysfunction and in people living with diabetes.

Combination of neuromuscular electrical stimulation and ibuprofen to reduce pain in femoral head necrosis.

The combinative effects of neuromuscular electrical stimulation and ibuprofen on pain in patients with femoral head necrosis were discussed and analyzed. This retrospective study analyzed data of 60 patients with femoral head necrosis hospitalized during Oct. 2020 to Oct. 2021. According to different treatment methods, the patients were divided into an observation group and a control group (30 cases in each group). The control group took oral ibuprofen sustained-release capsules, and the observation group was treated with neuromuscular electrical stimulation in addition to ibuprofen. Both groups received a 4-week treatment course. The therapeutic efficacy, Harris scale scores, Visual Analogue Scale (VAS) score, MRI hip imaging stage, SF-36 scale score, serum plasminogen activator inhibitor 1 (PAI-1), leptin and osteopontin levels before and after treatment were compared between the two groups. After treatment, the overall response rate in the observation group was higher than that in control group (P<0.05). The post-treatment scores of Harris scale were higher in both groups than those pre-treatment (P<0.05), and were higher in the observation group than in the control group (P<0.05). The VAS scores were decreased in both groups (P<0.05), and the decrease was more significant in the observation group than in the control group (P<0.05). After treatment, there were more patients with 0-I MRI hip imaging stage in the two groups than before treatment (P<0.05), and more in the observation group than in the control group (P<0.05). The SF-36 scores in both groups were increased (P<0.05), and the increase was more significant in the observation group than in the control group (P<0.05). The serum levels of PAI-1, leptin and osteopontin were decreased in both groups (P<0.05), and the decreases were more significant in the observation group than in the control group (P<0.05). The combinative treatment of neuromuscular electrical stimulation and ibuprofen has a significant effect on patients with femoral head necrosis. The treatment can remarkably reduce patients' pain, improve their hip function and quality of life, and decrease the PAI-1, leptin and osteopontin levels.

Correlation between Helicobacter pylori and serum levels of ghrelin, obestatin, leptin and motilin in hyperemesis gravidarum

Correlation between Helicobacter pylori and serum levels of ghrelin, obestatin, leptin and motilin in hyperemesis gravidarum
