Aim We aim to describe the pattern of response to treatment in a cohort of Egyptian lupus nephritis (LN) patients and to define variable prognostic factors. Methods We retrospectively analyzed records of 928 systemic lupus erythematosus (SLE) patients (898 females, 30 males) with biopsy-confirmed LN seen between 2006 and 2012 at Cairo University hospitals. Results Our study involved 928 SLE patients with a mean age of 26.25 ± 6.487 years, mean LN duration at time of renal biopsy 6.48 ± 4.27 months, mean SLEDAI 28.22 ± 11.7, and mean follow-up duration of 44.14 ± 17.34 months. Induction treatment achieved remission in 683 patients. Remission was achieved in all 32 patients with class II LN, compared to 651/896 (72.7%) patients in classes III, IV, and V. Induction by intravenous (IV) cyclophosphamide achieved response in 435/575 (75.7%) patients, while induction by mycophenolate mofetil (MMF) resulted in response in 216/321 (67.3%) patients ( p = 0.0068). Nephritic flares were least observed when MMF was used for maintenance (30/239 (12.6%) patients), compared to 71/365 patients (19.5%) ( p = 0.0266) when azathioprine (AZA) was used, and 22/79 patients (27.8%) ( p = 0.002) with IV cyclophosphamide. Class IV LN, high chronicity index, presence of crescents, and interstitial fibrosis in biopsies were all associated with chronic kidney disease (CKD) development eventually ( p < 0.001, p = 0.005, p = 0.012, and p = 0.031, respectively). By the end of the study duration, 305 (32.7%) patients had CKD. Logistic regression detected that high baseline serum creatinine, failure to achieve remission, hypertension, and nephritic flare were the main risk factors for poor renal outcome ( p < 0.001, p < 0.001, p = 0.004, and p < 0.001, respectively). The 5 years' mortality was 69 (7.4%) patients with sepsis being the main cause of death. Conclusion IV cyclophosphamide superseded as induction treatment, while MMF was the best maintenance treatment. High serum creatinine, hypertension, and nephritic flare were the main risk factors for poor renal outcome.

BackgroundOsteopontin (OPN) is a secreted glycoprotein and is frequently associated with various tumors.ObjectivesWe sought to investigate the clinical usefulness of the level of plasma OPN, compared to α-fetoprotein (AFP), as a biomarker for hepatocellular carcinoma (HCC) and to evaluate its diagnostic value in nonalcoholic fatty liver disease (NAFLD) and its relationship with clinical and laboratory features of HCC and NAFLD.Patients and MethodsThe study was performed on 120 subjects classified into 5 groups: Group I included 25 chronic non-cirrhotic hepatitis C virus (HCV)-infected patients; Group II encompassed 25 patients with chronic HCV infection with liver cirrhosis; Group III comprised 25 patients with chronic HCV with liver cirrhosis and HCC; Group IV was comprised of 25 patients with NAFLD; and Group V consisted of 20 healthy age- and sex-matched controls. All the participants were subjected to history taking and clinical and abdominal ultrasonographic examinations as well as the following laboratory investigations: liver function tests, complete blood count, blood sugar, hepatitis B surface antigen, hepatitis C virus antibodies, HCV-RNA by qualitative polymerase chain reaction (for Groups I, II, and III) and serum AFP and plasma OPN levels.ResultsThere were statistically significant differences in plasma OPN levels between the HCC group (401 ± 72 ng/mL) and the other groups, between the cirrhotic group (258.3 ± 35 ng/mL) and the non-cirrhotic group (HCV group, 168.7 ± 41 ng/mL; fatty liver group, 106.7 ± 35 ng/mL), and between the chronic non-cirrhotic HCV group and the fatty liver group (I and IV) and the controls (35.1 ± 6 ng/mL). In the HCC group, the diagnostic value of OPN was comparable to that of AFP at a cutoff value of 280 ng/mL, achieving sensitivity, specificity, and overall accuracy of 100%, 98%, and 96%, respectively. Regarding the validity of plasma OPN as a predictor of fatty change, our results revealed a diagnostic accuracy of 50% with 70% sensitivity, 45% specificity, 50% positive predictive value, and 75% negative predictive value at a cutoff value of 134 ng/mL.ConclusionsPlasma OPN is comparable to AFP as a diagnostic marker and is related to the severity of liver involvement in HCC patients. Plasma OPN is of diagnostic potential value in NAFLD.

To quantify the expression level of three lncRNAs which are known to be relevant to atherosclerosis (ANRIL, NOS3-AS, and APOA1-AS) in SLE patients and to assess their relationship with atherogenic and inflammatory biomarkers. The circulating levels of these lncRNAs were assessed using RT-PCR, in addition to measurement of E-selectin, V-CAM1, oxidized low-density lipoprotein (oxLDL), total nitric oxide (NOx), and lipid profile in 65 SLE patients (35 atherosclerotic and 30 non-atherosclerotic) and 35 healthy subjects. The expression levels of these lncRNAs were higher in SLE patients than in healthy controls. Importantly, a higher overexpression of these lncRNAs was noticed in atherosclerotic SLE patients than in non-atherosclerotic ones. In atherosclerotic SLE patients, level of ANRIL was positively associated with menopause, SLE duration, SLEDAI, and SLICC and negatively correlated with C3. Moreover, NOS3-AS expression was negatively correlated with total NOx level and HDL, while it was positively correlated with TC, LDL-C, hypertension, metabolic syndrome, obesity and dyslipidemia, CIMT, VCAM-1, E-selectin, oxLDL, SLEDAI, and SLICC. With respect to APOA1-AS, its expression was negatively correlated with HDL-C, whereas it was positively correlated with TC, LDL-C, hypertension, dyslipidemia, obesity, metabolic syndrome, menopause, CIMT, RI, V-CAM1, E-selectin, oxLDL, and SLICC. ANRIL, NOS3-AS, and APOA1-AS could be used as predictive biomarkers for atherosclerosis in SLE. Multivariate analyses identified these lncRNAs as independent predictors for atherosclerosis in SLE. These lncRNAs play a pivotal role in development of atherosclerosis via their significant repercussions atherogenic and inflammatory indices.

Burn scars are known for their tendency to worsen with hypertrophy and contracture, causing esthetic and functional problems. The objective is to analyze the effectiveness of low-level laser therapy on post-burn hypertrophic scar tissue in children. A randomized controlled study included 15 children, ranging from 2 to 10 years of age, presented with post-burn hypertrophic scars. They received He-Ne laser and topical treatment. Each scar was divided into two halves. One half was treated with laser therapy and topical treatment (study area), and the other half was treated with topical treatment only (control area). The children were evaluated before, and after 3 months of the study by Vancouver Scar Scale (VSS), ultrasonography, and laser Doppler perfusion imaging. Significant improvement was reported in the studied area, compared to the control area for patients with P values (P = 0.003) and (P = 0.005), for VSS and U/S scores, respectively. No differences were detected for blood perfusion of the scar between both areas (P = 0.73). In addition, no adverse effects were reported. Photobiomodulation (PBM) is an efficient and safe therapeutic modality for post-burn hypertrophic scars in children, with no side effects, and should be considered a part of combination therapy for better results.
