BACKGROUND: Gingivitis is a reversible condition; however, if left untreated, it progresses to periodontitis, which a serious infection that leads to bone destruction. Soluble urokinase-type plasminogen activator receptor (suPAR) measurement may be of value in the early assessment of gingivitis in children, thereby minimizing risk of tooth loss. OBJECTIVES: In this observational study, we assessed salivary and serum concentrations of suPAR for the diagnosis of gingivitis and correlation of salivary suPAR with the periodontal clinical parameters. METHODS: Ninety children participated in the study, with 20 healthy subjects as controls and 70 patients with gingivitis. The gingivitis group was divided into mild, moderate, and severe cases. According to the gingival index (GI), salivary and serum samples were analyzed for the suPAR and C-reactive protein levels using an enzyme-linked immunosorbent assay. RESULTS: The salivary suPAR was significantly higher in patients with gingivitis (10.8 ± 2.9 ng/mL) than in the control group (7.0 ± 1.1 ng/mL) as P < 0.001. SuPAR was correlated with gingivitis severity. It was 7.7 ± 1.5 1 ng/mL in mild cases, 10.9 ± 1.2 ng/mL in moderate cases, and 14.4 ± 0.9 ng/mL in severe cases. The difference was significantly high (P < 0.001) between the groups; however, the difference between the mild cases and the control was nonsignificant as P < 0.066. The salivary suPAR was correlated with periodontal clinical parameters, which included GI and simple oral hygiene index (SOHI). Conversely the serum suPAR was not correlated with the salivary suPAR or the periodontal clinical parameters. CONCLUSION: The results of the present study demonstrated that the salivary suPAR is increased in proportionate with the degree of severity of gingivitis in children. Moreover, salivary suPAR was correlated with the periodontal clinical parameters.

BACKGROUND AND AIM: Chronic kidney disease (CKD) is characterized by persistent low-grade inflammation. Soluble CD14 (sCD14) is involved in many pathological conditions including inflammation and atherosclerosis. The present study aimed to assess the relation between sCD14 levels, subclinical atherosclerosis (SCA), inflammation and mortality in Egyptian hemodialysis (HD) patients. PATIENTS AND METHODS: The present longitudinal study included 62 HD patients. All patients were submitted to careful history taking, thorough clinical examination and laboratory assessment for high-sensitivity C-reactive protein (hsCRP) and sCD14. Carotid intima-media thickness (CIMT) was also assessed. Patients were followed for a maximum of 18 months. The primary outcome is patients' mortality. Data were statistically analyzed using standard descriptive, comparative, correlative and regression methods. RESULTS: The present study was conducted on 62 HD patients. They comprised 34 males and 28 females with an age of 54.6 ± 9.0 years. At the end of follow up, 12 patients (19.4 %) died. It was shown that survivors had significantly lower hsCRP levels (104.2 ± 38.2 versus 134.1 ± 15.3 mg/dL, p <0.001), lower sCD14 levels (32.7 ± 10.3 versus 47.4 ± 18.4 µg/mL, p=0.02) and lower CIMT (1.32 ± 0.5 versus 1.5 ± 0.2 mm, p=0.049). sCD14 levels were significantly correlated with hsCRP (r=0.4, p=0.001) and CIMT (r=0.31, p=0.013). Multivariate analysis identified HD duration [HR (95% CI): 1.02 (1.0-1.04), p= 0.021] and sCD14 levels [HR (95% CI): 1.06 (1.0-1.12), p= 0.026] as significant predictors of patients' survival. CONCLUSIONS: sCD14 levels in this cohort of HD patients are well-correlated with hsCRP levels and CIMT. In addition, they are significant predictor of patients' mortality.

The purpose of this study was to assess the role of urinary IgG, serum CX3CL1 and miRNA 152-3p levels as predictors of nephropathy in type 2 Egyptian diabetic patients. Sixty type 2 diabetic patients and twenty healthy controls were enrolled in a cross-sectional study. Then they were grouped into: three groups based upon urine albumin excretion (UAE). The expression of miRNA 152-3p in serum was measured using quantitative polymerase chain reaction (RTq-PCR). Serum CX3CL1 and urinary IgG concentrations were measured by ELISA. RTq-PCR revealed that serum miRNA-152-3p levels in patients were significantly higher than in controls. There was significant differences between group with normoalbuminuria and groups with diabetic nephropathy DN as regard to age, duration of nephropathy, Albumin/Creatinine ratio (A/C ratio), creatinine, urine IgG, CX3CL1 and HbA1c. In diabetic patients, there was a significant positive correlation between miRNA-152-3p levels and disease duration only as well as significant positive correlations between urinary IgG levels and age, disease duration, serum creatinine, A/C ratio, and urea. Positive correlation between serum fractalkine CX3CL1 level and age, duration of disease, urea, creatinine, A/C ratio, HbA1C and IgG in patient with DN. Serum CX3CL1 level, urinary IgG were significantly increased with the progress of nephropathy so these integrated biomarkers could be used as good predictors for early identification of nephropathy. But miRNA- 152-3p has inadequate prognostic indicator for ESRD progression.

The purpose of this work was to prove that oxidative stress is the main mechanism responsible for retinal neurodegenerative changes, subsequent apoptosis, and inflammatory cytokine release in rats fed with a high cholesterol diet (HCD) and determine the role of garlic in alleviating these changes. Forty rats were equally divided into four groups: control, garlic-treated (positive control), HCD, and HCD + garlic-treated (HCD + G). By the end of the experiment (24 weeks) blood samples were collected for assessment of serum lipid profile, oxidative stress parameters, and plasma levels of IL-6 and TNF-α. Both eyes of the rats were enucleated; one was used for light microscopic examination and the other for electron microscopic examination. There was a significant increase in the levels of serum lipids, oxidative stress parameters, IL-6 and TNF-α, and area of expression of caspase-3 in the HCD group compared to both the control and HCD + G groups. Histological examination revealed degenerative changes in all layers of the neural retina in the HCD group. Garlic administration resulted in a significant improvement in the biochemical, immunohistochemical, and histological characteristics of hypercholesterolemic rats. These findings support the hypotheses that garlic has strong antioxidant, anti-apoptotic, and anti-inflammatory properties. Garlic ameliorates the neurodegenerative changes in the neural retina of hypercholesteremic rats.
