Conventional nonsteroidal anti-inflammatory drugs (NSAIDs) have a well-documented nephrotoxic action. Still, there are only few studies that have investigated the nephrotoxicity of cyclo-oxycenase-2-inhibitors during the perioperative period. Thirty patients scheduled for elective laparoscopic hysterectomy were enrolled in this prospective, randomized double-blind study. Patients were randomized into two groups: a saline-treated control group (placebo) and 80 mg parecoxib-treated group (parecoxib). The samples for the analyses of serum and urine were collected at the induction of anesthesia, two hours thereafter, two hours from the end of anesthesia, and on the first postoperative day (POD). S-crea, S-urea, S-cystatin C, S-Na, S-K, U-1mikroglobulin/U-crea, U-GST/U-crea, and U-GST/U-crea were analyzed from the samples. Urine output was measured every hour for the first five hours, and total amount of urine was measured until the first postoperative day. There were no clinical and few statistical significant differences between the two groups in the renal measurements during the study period. The urinary output was also similar in the two groups. A single dose of 80 mg of parecoxib was well tolerated by the kidneys in the short-term perioperative use in patients undergoing laparoscopic hysterectomy with ASA physiological status I-II and age under 60 years.

Purpose: The protein composition of aqueous humour (AH) has held significant relevance and remains to be the prime sample in the discovery of biomarkers in glaucoma. The purpose of this study is to analyze the AH protein concentrations in primary open angle glaucoma (POAG) and primary angle closure glaucoma (PACG) and further examine the proteome changes compared to cataract control. Methods: AH was collected from 90 POAG, 72 PACG, 78 cataracts (controls) in this study. The total protein was quantified using Bradford's assay. Samples were subjected to trypsin digestion followed by liquid chromatography-mass spectrometry (LC-MS) for proteomic studies (n = 3 per group). The extracellular matrix has a major influence on the AH outflow, and the regulator proteins osteopontin (OPN), cathepsin D, and cystatin C detected by mass spectrometry are validated in AH samples by Western blot and turbidimetric immunoassay. Results: We observed a significant increase in protein levels of POAG (p = .0009); interestingly, a similar increase in PACG compared to cataract (p < .0001) and POAG (p = .02). Proteomics analysis identified 184, 190, and 299 proteins in control, POAG and PACG. OPN was increased in POAG (p = .0319) and PACG (p = .0103) compared to control. The precursor form of cathepsin D was increased in POAG and decreased in PACG, though not significant compared to control. Cystatin C was also increased in both POAG (p = .0310) and PACG (p = .0125) compared to control. Conclusion: In this study, we report for the first time that PACG cohort had higher total protein compared to controls. A qualitative comparison of proteomes revealed increased numbers of proteins identified in PACG. We assume that elevated levels of OPN and cystatin C in POAG and PACG along with altered cathepsin levels may contribute to ECM aberration in glaucoma.
