Vitiligo is an acquired idiopathic skin disorder characterized by depigmented macules due to loss of cutaneous melanocytes. A potential role of the immune dysfunction has been suggested in vitiligo, so to test this hypothesis, certain cytokines (IL-17A and TNF-?) and immunoglobulins (IgM, IgG, IgA and total IgE) were investigated in all participants. The study included: 60 patients with age range between (6-55) year; 30(11 males and 19 females) were untreated and 30(12 males and 18 females) were treated with Narrow Band Ultraviolet-B (NB-UVB) and 30 (14 males and 16 females) apparently healthy control. Serum was separated and cytokines (IL-17A and TNF-?) and total immunoglobulin E (IgE) were detected by using Enzyme Linked Immunosorbent Assay (ELISA); while immunoglobulins (IgM, IgG and IgA) were detected by using Single Radial Immunodiffusion (SRID) method. The results showed that the mean levels of serum IL-17A and TNF-? in both untreated and NB-UVB treated vitiligo patients were increased significantly (p ? 0.05) as compared with healthy control. The mean levels of serum IgG and IgA in untreated vitiligo patients showed non significant decreased (P

 Objective: The present study was carried out to estimate the possible role of Interleukin-4 (IL-4)RαQ576R genes polymorphism in the development of immune reaction against penicillin, as well as to study the effect of IL-4 cytokine in regulating allergic reactions.Materials and Methods: Measurement of serum IL-4 concentration was done using enzyme-linked immunosorbent assay technique; IL-4RαQ576R gene polymorphisms were genotyped using polymerase chain reaction-restriction fragment lengths polymorphisms. Comparisons for statistical significance were performed using Mann–Whitney U-test.Results: Comparing with control subjects, there was a significantly increased level of IL-4 (348.53 pg/ml) in penicillin allergic patients versus (284.72 pg/ml) in sera of control subjects. The IL-4RαQ576R alleles were significantly higher in the penicillin allergic individual compared with apparently healthy control subjects.Conclusions: Data study suggested that IL-4 cytokine have some important roles in penicillin hypersensitivity reaction, additionally the IL- 4RαQ576Rgene polymorphisms might involve in modulating of penicillin hypersensitivity.

Object Chronic subdural hematomas (SDHs) are a local inflammatory process that causes the formation of a granulation tissue often referred to as the external or outer membrane. This membrane has abnormally permeable macrocapillaries. Therefore, exudation from the macrocapillaries in the outer membrane of chronic SDH may play an important role in the enlargement of chronic SDH. In this study the authors investigated the role of exudation in chronic SDH. Methods The authors examined 24 patients (16 men and eight women; age range 38–86 years [mean age 61.4 years]) with 27 chronic SDHs. The clinical status of the patients was evaluated according to the classification described by Markwalder. The diagnosis was established on computed tomography (CT) scans in all cases. The authors also used the Nomura Classification for judging the lesion's appearance on CT scans. Immediately after the diagnosis, all patients were administered 20 mCi (740 mBq) technetium-99m human serum albumin. Four hours later, blood and SDH samples were taken and radioactivity levels were measured in each. The ratio of activity of the samples taken from chronic SDH to the radioactivity of blood was determined as a percentage and defined as the exudation rate. On the follow-up CT scan obtained on postoperative Day 20, subdural collections thicker than 5 mm were determined to be a reaccumulation. Results The correlations between the exudation rate and age of the patients, clinical grades, CT appearances, and amount of reaccumulation were investigated. In this series the average exudation rate was 13.24% (range 2.05–28.88%). The mean exudation rates according to the clinical grades assigned to patients were as follows: Grade 0, 8.67 ± 5.64% (three patients); Grade 1, 5.07 ± 1.43% (eight patients); Grade 2, 17.87 ± 3.73% (seven patients); and Grade 3, 19.65 ± 7.67% (six patients). Exudation rates in patients with Grades 2 and 3 were significantly higher than those in Grades 0 and 1 (p < 0.05). The mean exudation rates according to the lesion's appearance on CT scans were found as follows: hypodense appearance, 6.55 ± 4.52% (eight patients); isodense appearance, 11.07 ± 6.32% (five patients); hyperdense appearance, 19.47 ± 13.61% (three patients); and mixed-density appearance, 17.40 ± 5.80% (nine patients). The differences among the groups were significant (p < 0.05). The average exudation rate was statistically higher in the patients with reaccumulation (16.30 ± 8.16%) than that in the patients without reaccumulation (9.96 ± 6.84%) (p < 0.05). Conclusions The exudation rate in chronic SDH is correlated with a higher clinical grade (Markwalder Grade 2 or 3), mixed-density CT appearance, and reaccumulation. Therefore, exudation from macrocapillaries in the outer membrane of chronic SDH probably plays an important role in the pathophysiology and the growth of chronic SDH.

Background: Among the most common complications of diabetes is diabetic neuropathy (DN). Diabetic neuropathy is a heterogeneous group of disorders, which involves a different part of somatic and autonomic nervous systems, with a gradual loss of neural conductivity. Some studies have shown that they reduce the activity of the Na/K ATPase, however, elevated levels of endogenous sodium pump inhibitor in diabetic individuals, including those with neuropathy. Changes in this transfer enzyme are believed to be due to several diabetes complications. Objective: The study had designed to evaluate the Na/K ATPase enzymatic activity in the erythrocyte-membrane among three groups. The first group had represented the patients with type 2 diabetes mellitus (DM2) and neuropathy. The second group is diabetics without neuropathy. The third group was a healthy subject. As well, the study had estimated the inhibitory activity of endogenous digitalis among patient groups. Furthermore, the aim of this research was to see whether there was a connection between red blood cell membrane Na-K ATPase activity and the medical facts of the analysis subjects. Design and Methods: One-hundred fifty subjects had enrolled in this case-control study; 80 patients complained of diabetic neuropathy of both sexes, the mean age 59.3 years with an age range of 40-81, 40 DM2 without neuropathy (53.9 years), (35 – 70), and 30 healthy controls (30 years, 25 to 45). Patients in the first group were selected carefully according to their clinical manifestations and the nerve conduction study results. The evaluations of both inhibitory activities of endogenous digitalis and Na/K ATPase had completed using a spectrophotometer. Enzyme activity had expressed in micrograms of phosphate concentration per grams of red cell ghost total protein concentration. Results: The mean enzyme activity of Na/K ATPase was significantly lower (p<0.001) in patients with diabetic neuropathy (381±17.9) compared with the diabetic group without neuropathy (498±22.9) and the normal controls (837±61.43). There was a significant inhibitory activity of endogenous digitals (17.87±2.15) in patients with DNP, compared with the diabetics without neuropathy (8.78±0.89) and healthy control (5.3±1.33). There was a significant association of enzyme activity with the following parameters: duration of diabetes, age, level of glycated hemoglobin and endogenous digitalis with the respective p-values (0.000, 0.000, 0.000 and 0.021). Gender showed no significant relationship with enzyme activity (p 0.43). Conclusions: In DM2 with neuropathy, hyperglycemia can much reduce the activity of erythrocyte Na/K ATPase. In addition, it may enhance the inhibitory activity of endogenous digitals. The timedependent increase in diabetic complications can be due to a strong association between diabetes duration and erythrocyte Na/K-ATPase activities.

Background: A link between major depressive disorder (MDD) and haematological as well as co-agulation disorders has been postulated. This study aims to evaluate haematological and haemostatic changes among Nigerians with major depressive disorder Methods: Two hundred volunteers consisting of an equal number of individuals diagnosed with major depressive disorder (MDD) based on DMS-IV criteria and apparently healthy control participated in this study. The blood sample was collected into tri-sodium citrate K2EDTA bottles respectively and was evaluated for some haemostatic parameters , using ELISA, Clauss, Quick’s One Stage, Proctor and Rapaport’s methods. Results: The mean WBC, hemoglobin and differential lymphocyte were significantly higher among MDD total volunteers (p < 0.001). The red cell indices and platelet count were lower among MDD (p <0.001). Also the prothrombin time (PT), fibrinogen, protein-C and erythrocytes sedimentation rate (ESR) were all raised (p <0.001) among volunteers with MDD. Positive associations existed be-tween MCV and RBC (r: 0.364; p<0.001), PT and APTT (r: 0.319 p <0.001), APTT and fibrinogen (r: 0.239, p = 0.017) as well as PT and fibrinogen (r: 0.275 p = 0.006) at 95% confidence interval. Conclusion: Changes in total leucocytes count, lymphocytes values and haemostatic parameters among volunteers with depression may impacts deleterious effects on the immune response as well as haemostatic homeostasis, while decreased red cell indices may suggest occult nutritional anaemia.

Abstract PURPOSECarbonic anhydrase-2 (CA-2) plays a role in mineralization and calcification in organism. Strong evidence suggests that CA-2 is associated with urolithiasis. However, the relationship between CA-2 and urinary stone remains unclear. The study aimed to assess the association of urine CA-2 (uCA-2) level and the potential risk of urinary stone.METHODSFrom March 2017 to November 2019, a prospective cohort study was conducted on patients with urinary stones and healthy subjects to determine the pretreatment uCA-2 level detection by Enzyme linked immunosorbent assay (ELISA). The difference of uCA-2 level between patients with urinary stones and healthy subjects was compared. Then comparison between stone patients with complications and without complications was carried out as well as correlation analysis to detect factors associated with biomarker expression.RESULTS118 patients with urinary stones were into urinary stones group and 42 healthy subjects were into healthy control group. The mean pretreatment uCA-2 level was significantly higher in patients with urinary stones group than healthy controls group (P=0.028). Furthermore, The uCA-2 level was positive correlation with urinary stones complications (R=0.379, P=0.000), especially pain complications (R=0.524, P=0.000) and hematuria complications (R=0.374, P=0.000). Receiver operating characteristic curve (ROC) analysis that a uCA-2 level threshold of 10.94 ng/mL had 83.67% sensitivity and 68.12% specificity for predicting urinary stones complications. CONCLUSIONSExcessive uCA-2 excretion is a major risk factor for urinary stone. Our findings suggested that uCA-2 may be used as an unappreciated biomarker for the diagnosis urinary stone in patients and to predict its complications.

Background: Rheumatoid arthritis (RA) is a inflammatory disease that characterized with the destruction of synovial joint, which could induce disability. Inflammatory response mediated the RA. It has been reported that MiR-128-3p is significantly increased in RA, while the potential role was still unclear. Methods: T cells in peripheral blood mononuclear cell (PBMC) were isolated from the peripheral blood from people of RA and normal person were used. Real-time PCR was performed to detect the expression of MiR-128-3p, while the protein expression of tumor necrosis factor-α-induced protein 3 (TNFAIP3) was determined using Western blot. The levels of IL-6 and IL-17 were measured using enzyme-linked immunosorbent assay (ELISA). The expression of CD69 and CD25 was detected using flow cytometry. The RA mouse model was constructed for verification of the role of MiR-128-3p. Results: The expression of MiR-128-3p was significantly increased, while TNFAIP3 was decreased, the levels of IL-6 and IL-17 were also increased in the T cells of RA patients. Down-regulated MiR-128-3p significantly suppressed the expression of p-IkBα and CD69, and CD25in T cells. MiR-128-3p targets TNFAIP3 to regulate its expression. MiR-128-3p knockdown significantly suppressed the activity of nuclear factor κB (NF-κB) and T cells by up-regulating TNFAIP3, while cells co-transfected with si-TNFAIP3 abolished the effects of MiR-128-3p knockdown. The in vivo experiments verified the potential role of MiR-128-3p on RA. Conclusion: Down-regulated MiR-128-3p significantly suppressed the inflammation response of RA through suppressing the activity of NF-κB pathway, which was mediated by TNFAIP3.

Abstract Kaposi sarcoma-associated herpesvirus encodes viral IL-6 (vIL-6). To investigate the potential role of vIL-6 in the pathogenesis of human immunodeficiency virus (HIV)- related primary effusion lymphomas (PEL), a sensitive enzyme-linked immunosorbent assay was developed for vIL-6 and applied to the study of PEL. Whereas vIL-6 was detectable in 6 of 8 PEL effusions (range, 1390-66 630 pg/mL), it was not detectable in any of the control effusions. As expected, all PEL effusions contained human IL-6 (range, 957-37 494 pg/mL), and 7 of 8 contained detectable human IL-10 (range, 66-2,521,297 pg/mL). Human and vIL-6 have previously been shown to induce vascular endothelial growth factor, which in turn can increase vascular permeability. The results of the current study suggest that these cytokines play a central role in the pathogenesis and manifestations of PEL.

Background and objectives: T-cadherin (T-cad) is one of the adiponectin receptors abundantly expressed in the heart and blood vessels. Experimental studies show that T-cad sequesters adiponectin in cardiovascular tissues and is critical for adiponectin-mediated cardio-protection. However, there are no data connecting cardiac T-cad levels with human chronic heart failure (HF). The aim of this study was to assess whether myocardial T-cad concentration is associated with chronic HF severity and whether the T-cad levels in human heart tissue might predict outcomes in patients with non-ischemic dilated cardiomyopathy (NI-DCM). Materials and Methods: 29 patients with chronic NI-DCM and advanced HF were enrolled. Patients underwent regular laboratory investigations, echocardiography, coronary angiography, and right heart catheterization. TNF-α and IL6 in serum were detected by enzyme-linked immunosorbent assay (ELISA). Additionally, endomyocardial biopsies were obtained, and the levels of T-cad were assessed by ELISA and CD3, CD45Ro, CD68, and CD4- immunohistochemically. Mean pulmonary capillary wedge pressure (PCWP) was used as a marker of HF severity, subdividing patients into two groups: mean PCWP > 19 mmHg vs. mean PCWP < 19 mmHg. Patients were followed-up for 5 years. The study outcome was composite: left ventricular assist device implantation, heart transplantation, or death from cardiovascular causes. Results: T-cad shows an inverse correlation with the mean PCWP (rho = −0.397, p = 0.037). There is a tendency towards a lower T-cad concentration in patients with more severe HF, as indicated by the mean PCWP > 19 mmHg compared to those with mean PCWP ≤ 19 mmHg (p = 0.058). Cardiac T-cad levels correlate negatively with myocardial CD3 cell count (rho = −0.423, p = 0.028). Conclusions: Univariate Cox regression analysis did not prove T-cad to be an outcome predictor (HR = 1, p = 0.349). However, decreased T-cad levels in human myocardium can be an additional indicator of HF severity. T-cad in human myocardium has an anti-inflammatory role. More studies are needed to extend the role of T-cad in the outcome prediction of patients with NI-DCM.

Objective The identification of early-stage osteoarthritis (OA) is crucial for the deceleration of its progression; however, no reliable biomarker is available for this purpose. The current study aimed to determine the role of serum calprotectin in the detection of early-stage knee OA. Design In a case-control study, serum samples were collected from 84 patients with primary bilateral knee OA and 52 healthy controls. The radiographic grading of knee OA was performed using the Kellgren-Lawrence classification system. Serum concentrations of calprotectin were measured using an enzyme-linked immunosorbent assay. Results The mean serum calprotectin level was 2908 ± 2516 ng/mL in OA patients and 901 ± 875 ng/mL in healthy control subjects ( P < 0.001). Mean serum calprotectin levels were significantly higher in the lower stages of OA: 3740 ± 2728 ng/mL in OA grade I, 3100 ± 2084 ng/mL in OA grade II, 2246 ± 1418 ng/mL in OA grade III, and 2035 ± 765 ng/mL in OA grade IV ( P = 0.047). Serum calprotectin levels were significantly higher in patients with a disease duration <42 months compared with those with a disease duration >42 months ( P = 0.043). Conclusion Serum calprotectin level increases significantly in the early stages of OA and shows a reverse association with disease severity. Therefore, it could be suggested as a promising blood-based marker for early-stage knee OA.

<b><i>Introduction:</i></b> The endoscopic resection of large and bulky bladder cancers represents a challenge. To reduce the tumor and make it more easy to resect, we used neoadjuvant short and intensive intravesical mitomycin (MMC) therapy. <b><i>Methods:</i></b> Patients with large bladder tumors were evaluated for this study. At cystoscopy, the surgeon evaluated the feasibility of complete resection. In patients where this was not possible, biopsies from the tumor, bladder mucosa, and prostatic urethra were taken. These patients then underwent a short and intensive cytoreductive schedule of intravesical MMC. This was then followed by TUR-BT. <b><i>Results:</i></b> Fifteen patients were included in our study. The mean age was 74 years (range: 56–82; SD ±6 years). Mean tumor size was 51 mm (range: 35–65; SD ±8 mm). After neoadjuvant treatment, complete resection was then feasible in all patients. The mean tumor volume after the chemo-resection had reduced to 34 mm (range: 10–50; SD ±13 mm). No adverse effects were reported. <b><i>Conclusion:</i></b> Intravesical cytoreductive neoadjuvant MMC as an initial treatment of large NMIBC can be considered safe, effective, and feasible.
