Pharmacological effect of Argyrolobium roseum (Camb.) Jaub & Spach extracts against lead-induced toxicity in rats

Argyrolobium roseum (Camb.) Jaub & Spach (Papilionaceae) is a medicinal plant, cultivated in northern areas of Pakistan. The consumption of trace minerals (lead) is very toxic to the vital organs of the body, therefore the overcome of these minerals is very necessary. In this regard, this study aimed to assess the potential pharmacological effect of aqueous and ethanolic extract of Argyrolobium roseum (Camb.) Jaub & Spach against pb-induced oxidative stress, histological changes in Pb-induced rats' liver and kidney, and anti-inflammatory effect. The metal concentrations in liver and kidney homogenates were measured through atomic absorption spectrophotometer. The antioxidant activity was measured through DPPH and FRAP assay. Pb concentrations were significantly higher in liver and kidney homogenates after injection of Pb acetate was given intraperitoneally (45.2 ± 6.8 and 58.8 ± 7.9, respectively; p < .0001). The level of Pb in liver and kidney homogenates was significantly reduced by aqueous and ethanolic extracts of Argyrolobium roseum (Camb.) Jaub & Spach. The Pb + Aq-600 mg/kg-treated rats exhibited a protective effect on hepatocytes cells against Pb-induced liver injury and restored the cells of the kidney. Pb + Aq-600 mg/kg showed higher antioxidant activity as compared to other treated groups. The highest decreased MDA level was found in liver and kidney homogenate of Pb + Aq-600 mg/kg rats (11.2 ± 1.51 nmol/mg; p < .001) and GSH and CAT levels tended to normal after treatment of Pb + Aq-600 mg/kg in rats. The ALAD, ALT, AST, and ALP level were enhanced and tended to be normal after the Aq-400 and Aq-600 mg/kg treatment in Pb-exposed rats. The result showed that 600 mg/kg Aq + Pb exhibited significant (p < .001) anti-inflammatory activity. The findings of this study concluded that treatment of the aqueous extract of Argyrolobium roseum (Camb.) Jaub & Spach reduces the renal and hepatic damage in Pb-induced rats and it also decreases oxidative stress via improving antioxidant components.

Analgesic effectiveness and safety of celecoxib versus non-opioid active controls after third molar surgery: A meta-analytical evaluation

The aim of this meta-analysis was to assess the analgesic efficacy and adverse effects of celecoxib compared to non-opioid drugs after third molar surgery. A search in PubMed and Google Scholar was performed to identify clinical trials, and then, the Cochrane Collaboration's toll for assessing risk of bias tool was used to evaluate the quality of all clinical trials. Studies without any high-risk of bias were included in the statistical analysis. The data extraction included the pain intensity measured by the visual analogue scale (VAS), the number of patients using rescue analgesics and adverse effects of gastric (nausea and vomiting), and nervous (dizziness and headache) systems. Data were analyzed using the Review Manager Software 5.3 for Windows and the Risk Reduction Calculator. The visual analog scale, total pain relief, and the number of patients who needed rescue analgesics showed statistical significance. Moreover, celecoxib had a lower frequency of nausea and vomiting compared with ibuprofen. In conclusion, celecoxib was more effective than acetaminophen and ibuprofen for pain control after third molar surgery.

Thiazole Ring-A Biologically Active Scaffold

BACKGROUND

Thiazole is a good pharmacophore nucleus due to its various pharmaceutical applications. Its derivatives have a wide range of biological activities such as antioxidant, analgesic, and antimicrobial including antibacterial, antifungal, antimalarial, anticancer, antiallergic, antihypertensive, anti-inflammatory, and antipsychotic. Indeed, the thiazole scaffold is contained in more than 18 FDA-approved drugs as well as in numerous experimental drugs.

OBJECTIVE

To summarize recent literature on the biological activities of thiazole ring-containing compounds Methods: A literature survey regarding the topics from the year 2015 up to now was carried out. Older publications were not included, since they were previously analyzed in available peer reviews.

RESULTS

Nearly 124 research articles were found, critically analyzed, and arranged regarding the synthesis and biological activities of thiazoles derivatives in the last 5 years.

The clinicopathological features of drug-induced acute kidney injury-a single-center retrospective analysis

Background

This study aimed to analyze changes to the drug spectrum and clinicopathological features of drug-induced acute kidney injury (AKI) with recent medication habits changes.

Methods

A retrospective analysis of the characteristics of patients diagnosed with drug-induced AKI from January 2012 to October 2016 period at the First Affiliated Hospital of the Medical College of Zhejiang University was conducted.

Results

Between January 2012 and October 2016, 909 patients were diagnosed with AKI. Of these, 228 were diagnosed with drug-related AKI were engaged in this study, including 51 who underwent renal biopsies, 74 treated with antibacterial and antiviral drugs, and 63 who received nonsteroidal anti-inflammatory drugs (NSAIDs), and 17 who were treated with Chinese herbal medicine. AKI was most frequently associated with antibiotics and antiviral drugs, including cephalosporins, acyclovir, azithromycin, clindamycin, and levofloxacin. In those who underwent renal biopsy, 12 patients were diagnosed with allergic interstitial nephritis, 19 with interstitial nephritis, 8 with renal tubular epithelial cell injury, 2 with minimal change nephropathy, 2 with IgA nephropathy, and 2 with mild mesangial hyperplasia with glomerulosclerosis. The mean follow-up time was 437 days, ranging from 3 to 2,756 days. Among 228 patients, 165 recovered completely, 4 recovered partially, 8 did not recover, and 51 were lost to follow-up after discharge.

Conclusions

The three main contributors to drug-induced AKI were antimicrobial agents, NSAIDs, and Chinese herbal medicines. The age distribution of the three different drug-induced AKI groups was significantly different. Allergic interstitial nephritis, interstitial nephritis, and tubular epithelial cell injury were the main pathological manifestations of drug-induced AKI. The novel predictive nomogram achieved a good performance of prediction recovery within 2 weeks in drug-induced AKI patients.

Brazilian recommendations for the use of nonsteroidal anti-inflammatory drugs in patients with axial spondyloarthritis

Spondyloarthritis (SpA) is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. Over some decades, nonsteroidal anti-inflammatory drugs (NSAIDs) have been the basis for the pharmacological treatment of patients with axial spondyloarthritis (axSpA). However, the emergence of the immunobiologic agents brought up the discussion about the role of NSAIDs in the management of these patients. The objective of this guideline is to provide recommendations for the use of NSAIDs for the treatment of axSpA. A panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis of randomized clinical trials for 15 predefined questions. The Grading of Recommendations, Assessment, Development and Evaluation methodology to assess the quality of evidence and formulate recommendations were used, and at least 70% agreement of the voting panel was needed. Fourteen recommendations for the use of NSAIDs in the treatment of patients with axSpA were elaborated. The purpose of these recommendations is to support clinicians' decision making, without taking out his/her autonomy when prescribing for an individual patient.

Drug Class Combination–Associated Acute Kidney Injury

Objective: To evaluate the quality of available evidence of drug class combinations and their association with the development of acute kidney injury (AKI). Data Sources: A search of MEDLINE and Embase databases was completed using the following terms: “risk factor AND (acute kidney injury or acute kidney failure) AND (drug or medication).” Study Selection and Data Extraction: Inclusion criteria were the following: English language, full-text availability, and at least 1 drug-combination. Each citation was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. The literature was evaluated using the quality of evidence component of GRADE. No standardized definition of AKI was applied throughout.. Data Synthesis: Out of 2139 total citations, 151 were assessed for full-text review, with 121 citations (6%) meeting inclusion criteria, producing76 unique drug class combinations. Overall, 56 combinations (73.7%) were considered very low quality; 12 (15.8%) were considered low quality. There were 8 (10.5%) of moderate quality, and no combination was considered high quality. 58 (76%) combinations that had a single citation,with a mean of 1.6 citations per drug class combination. The combination of nonsteroidal anti-inflammatory drugs (NSAIDs) and diuretics was reported in 10 citations, the largest number of citations. Conclusions: Our study demonstrates a lack of well-designed studies addressing drug class combination–associated AKI. The combination of NSAIDs and diuretics with or without additional renin-angiotensin aldosterone agents had the strongest level of evidence. Despite limitations, the information included in this review may result in additional scrutiny about combining certain individual nephrotoxic drugs.
