Egyptian patients with axial spondyloarthritis: The frequency and predictors of renal impairment

Aim of the workTo determine the frequency of and risk factors for renal impairment in patients with axial spondyloarthritis (axSpA). Patients and methodsFifty axSpA patients participated in this study. In accordance with the Kidney Disease Outcomes Quality Initiative (K/DOQI) criteria, patients were split into two groups: group 1comprised renal impairment and group 2 comprised non-renal impairment. The ankylosing spondylitis (AS) disease activity score (ASDAS), Bath AS disease activity index (BASDAI) and estimated glomerular filtration rate were assessed. ResultsThe mean age of patients was 38.9 ± 11.7 years, males were 54 % and the disease duration was 11.36 ± 6.1 years. The mean ASDAS score was 5.58 ± 1.38 and BASDAI was 5.18 ± 1.55. The eGFR was 76.4 ± 36.2 ml/min/1.73 m2 and 28 % had positive human leucocytic antigen (HLA-B27). 80 % were receiving biologic therapy. Nephropathy by ultrasound and renal impairment were detected in 34 % and 52 % of the cases respectively. The cumulative dose of non-steroidal anti-inflammatory drugs (NSAIDs), C-reactive protein, erythrocyte sedimentation rate, low density cholesterol, blood urea nitrogen, creatinine, proteinuria, ASDAS and BASDAI were significantly higher in those with renal impairment(p = 0.0001, p = 0.0001, p = 0.001, p = 0.035, p = 0.0001, p = 0.0001, p = 0.0001, p = 0.001, p = 0.001 respectively) while the eGFR and high density lipoprotein were significantly lower (p = 0.001and p = 0.02). Only the cumulative dose of NSAIDs was a significantly independent variable influencing the development of renal impairment (OR=1.01, CI; 1.001–1.02, p = 0.024) at cut-off level > 1166.3 g. ConclusionsRenal impairment is frequent in axSpA patients with decreased eGFR and high disease activity. The cumulative dose of NSAIDs is a significant predictor of renal impairment.

Study on Impact of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) on Renal Function in Postpartum Period

A prospective, observational study was conducted in the Department of Obstetrics & Gynaecology of Combined Military Hospital (CMH), Dhaka, Bangladesh, to assess pre-delivery and post-delivery (5 days after administration of NSAID) change in renal function by determining the serum creatinine levels in pregnant women. The study was conducted on 120 purposively selected patients attending for their delivery purpose in the selected hospital from January to June of 2022. Following the delivery, tablet Paracetamol 500 mg thrice a day for 5 days have been prescribed to all the respondents. Diclofenac Sodium 100 mg suppository twice a day up to for 3 days had been prescribed with dosage adjusted as required. Serum creatinine levels were evaluated on two time points: the day before delivery and 5 days after delivery. Compared to the day before delivery, 53.3% of the respondents showed increased level of serum creatinine 5 days after delivery. Acute kidney injury (AKI) was identified in 9.17% patients with a change more than 0.3 mg/dL from the pre-delivery report. The change in the serum creatinine level pre-delivery to post delivery was statistically significant, which was also dependent on the NSAIDs dose with a positive linear association. Though NSAIDs regarded as a safe choice for postpartum pain management, yet apparently healthy mothers showed fluctuations in serum creatinine level in association to dosage of NSAIDs use.

Use of Nonsteroidal Anti-Inflammatory Drugs and Pancreatic Cancer Risk in the Women's Health Initiative.

Pancreatic cancer is among the most fatal human cancers and the fourth leading cause of cancer death in the United States. Evidence suggests that chronic inflammation may play a role in pancreatic carcinogenesis and its inhibition through nonsteroidal anti-inflammatory drugs (NSAID) may reduce pancreatic cancer incidence. We examined associations of total and individual NSAIDs with pancreatic cancer risk among postmenopausal women participating in the Women's Health Initiative observational study and clinical trial cohorts. Among 117,452 women, aged 55 to 79 years, 727 incident pancreatic cancer cases were reported over 18 years of follow-up. Cox regression was used to estimate hazard ratio (HR) and 95% confidence interval (CI) for associations between NSAIDs and pancreatic cancer risk. Relative to non-use, consistent use of any NSAID was inversely associated with pancreatic cancer risk (HR 0.71, 95% CI, 0.59-0.87), primarily driven by strong associations for aspirin use (HR 0.67, 95% CI, 0.52-0.86). Use of total or individual non-aspirin NSAIDs was not associated with pancreatic cancer. Upon stratified analysis, we observed stronger associations for NSAIDs among participants with prevalent diabetes (HR 0.28, 95% CI, 0.10-0.75) relative to those without (HR 0.75, 95% CI, 0.61-0.92; P-interaction = 0.03). Additional large prospective studies with careful measurement of NSAID type, dose, and frequency are needed to further investigate the possibility of added benefit among individuals diagnosed with diabetes. This study adds to existing evidence from prospective studies and clinical trials suggesting that use of aspirin may provide moderate benefit for pancreatic cancer prevention.

Continuous co-prescription of rebamipide prevents upper gastrointestinal bleeding in NSAID use for orthopaedic conditions: A nested case-control study using the LIFE Study database.

Rebamipide has been widely co-prescribed with non-steroidal anti-inflammatory drugs (NSAIDs) in Japan for decades. This study aimed to evaluate the effectiveness of rebamipide in preventing upper gastrointestinal bleeding in new users of NSAIDs without risk factors of NSAID-induced ulcers other than age. A nested case-control study was conducted using medical claims data of 1.66 million inhabitants of 17 municipalities participating in Japan's Longevity Improvement & Fair Evidence study. The cohort entry (t0) corresponded to a new user of NSAIDs for osteoarthritis or low back pain. Patients with risk factors of NSAID-induced ulcers other than age were excluded. Cases were defined as patients who underwent gastroscopy for upper gastrointestinal bleeding (occurrence date was defined as index date). A maximum of 10 controls were selected from non-cases at the index date of each case by matching sex, age, follow-up time, and type and dosage of NSAIDs. Exposure to rebamipide was defined as prescription status from t0 to index date: Non-user (rebamipide was not co-prescribed during the follow-up period), Continuous-user (rebamipide was co-prescribed from t0 with the same number of tablets as NSAIDs), and Irregular-user (neither Non-user nor Continuous-user). Conditional logistic regression analysis was conducted to estimate each category's odds ratio compared to non-users. Of 67,561 individuals who met the inclusion criteria, 215 cases and 1,516 controls were selected. Compared with that of Non-users, the odds ratios and 95% confidence interval were 0.65 (0.44-0.96) for Continuous-users and 2.57 (1.73-3.81) for Irregular-users. Continuous co-prescription of rebamipide significantly reduced the risk of upper gastrointestinal bleeding in an Asian cohort of new users of NSAIDs with osteoarthritis or low back pain without risk factors other than age.

Prescription of non-steroidal anti-inflammatory drugs for patients with inflammatory arthritis decreases with the initiation of tumour necrosis factor inhibitor therapy: results from the ICEBIO registry

Objective To study the impact of tumour necrosis factor-α inhibitor (TNFi) therapy on the use of non-steroidal anti inflammatory drugs (NSAIDs) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) in Iceland. Method This registry cohort study used data from the nationwide database on biologics in Iceland (ICEBIO) and the Icelandic Prescription Medicines Register on disease activity, and filled prescriptions for NSAIDs, to study the period from 2 years before to 2 years after initiation of a first TNFi. Five randomly selected individuals from the general population matched on age, sex, and calendar time for each patient served as comparators. Results Data from 940 patients and 4700 comparators were included. Patients with arthritis were prescribed 6.7 times more defined daily doses of NSAIDs than comparators (149 vs 22 per year). After TNFi initiation, NSAID use decreased to a mean of 85 DDD per year, or by 42% in RA, 43% in PsA, and 48% in axSpA. At TNFi initiation, the quintile of axSpA patients who used most NSAIDs reported significantly worse pain (mean ± sd 66 ± 21 vs 60 ± 23 mm), global health (70 ± 20 vs 64 ± 23 mm), and Health Assessment Questionnaire score (1.21 ± 0.66 vs 1.02 ± 0.66) than the other patients, whereas no significant differences were observed in the groups with peripheral arthritis. Conclusion Patients with inflammatory arthritides requiring TNFi therapy use more NSAIDs than matched comparators, and consumption decreased following TNF initiation. Patient-reported measures are not associated with high NSAID use in patients with peripheral arthritis.

Risk of cardiovascular disease with high-dose versus low-dose use of non-steroidal anti-inflammatory drugs in ankylosing spondylitis

ObjectiveTo investigate the risk of cardiovascular disease (CVD) associated with increasing dose of a non-steroidal anti-inflammatory drug (NSAID) in patients with ankylosing spondylitis (AS).MethodsUsing the Korean National Health Insurance database,...

A comparative study on the efficacy of over-the-counter wax solvents versus distilled water for managing ear cerumen

Abstract Background: Ear wax, or cerumen, is a naturally occurring hydrophobic waxy substance frequently encountered in otorhinolaryngology practices. Despite the abundance of water- and oil-based ceruminolytic agents available nowadays, there remains a lack of consensus regarding the preferred agent type, composition, or ideal treatment duration. Aims and Objectives: The study aimed to assess the efficacy of using distilled water as a wax-softening agent for ear wax removal and determine its advantages compared to over-the-counter (OTC) ceruminolytics. Materials and Methods: This double-masked, randomized prospective cohort study enrolled 236 patients seeking treatment for ear wax-related concerns at the Ear, Nose, Throat outpatient department. The cohort exclusively consisted of cases involving right ear wax, which were then randomly allocated into two groups: group A received distilled water ear drops, whereas group B received OTC ceruminolytic ear drops containing a combination of paradichlorobenzene with turpentine oil, benzocaine, and chlorbutol. Evaluation of patients took place pre- and post-intervention, focusing on three key parameters: the total duration required for ear suctioning, any additional instrumentation employed, and the occurrence of pre-procedure and post-procedure complications. Results: Out of the total 118 participants in the study, they were randomly distributed with 67 males and 51 females in group A and 63 males and 55 females in group B. During the pre-intervention complication assessment, nine subjects in group A reported ear blockage, whereas four subjects in group B did so. Additionally, two subjects in group A complained of pain, whereas none in group B did. Furthermore, five subjects in group A developed otitis externa, compared with three in group B. The average time required for ear suctioning to visualize the tympanic membrane was 9.24 ± 2.50 min in group A and 9.68 ± 2.18 min in group B. During the intervention, nine subjects in group A experienced pain during wax removal, whereas only six patients in Group B reported pain. After the interventions, five patients in group A complained of increased ear pain compared with seven in group B. Mild post-interventional pain was managed with an as-needed dosage of nonsteroidal anti-inflammatory drugs Statistically significant differences were observed in the study parameters between the subjects of the two groups. Conclusion: This study confirms that distilled water can serve as a viable method for dispersing wax, proving its efficacy comparable with commercially available OTC ceruminolytics.

Non-steroidal anti-inflammatory drugs, renin-angiotensin system blockade or diuretics and risk of acute kidney injury: A case-crossover study

BackgroundAging-related physiological changes, such as decline in renal function, not only exacerbates pre-existing comorbidities but also escalate the susceptibility to adverse events. Previous studies have shown that non-steroidal anti-inflammatory drugs (NSAIDs) are associated with an increased risk of acute kidney injury (AKI), and the concomitant use of renin-angiotensin system blockade or diuretics may further potentiate the risk. However, studies evaluating the risk of AKI associated with NSAIDs (including routes, concomitant use of different NSAIDs, categories (traditional NSAIDs or COX-2 inhibitors), and cumulative doses of NSAIDs) are limited, particularly the risk of AKI associated with the dual or triple combination of NSAIDs with renin-angiotensin system blockade (RAS blockades) and/or diuretics. MethodsA case-crossover study utilized two sets of longitudinal data from Taiwan's National Health Insurance Research Database (NHIRD). Newly admitted patients with a primary AKI diagnosis were included, with the index date defined as the first admission date. The 1–7 days and 181–187 days prior to the index date served as the case and control periods. Exposure to NSAIDs and co-exposures of RAS blockade and/or diuretics were assessed in both periods. Multivariable conditional logistic regression models, adjusting for potential confounders, estimated adjusted odds ratios (aORs) and 95 % confidence intervals (CIs) for AKI associated with NSAIDs, dual, or triple combinations. Sensitivity analyses explored result robustness by varying case and control period lengths. ResultsThe study included 1,284 newly diagnosed AKI patients. NSAIDs showed a 3.55-fold increased risk of AKI (aOR: 3.55; 95 % CI 2.70–4.65), with similar risks for traditional NSAIDs and COX-2 inhibitors. Use of multiple NSAIDs, parenteral dosage forms, and higher cumulative doses increased AKI risk. Dual combination with either RAS blockade or diuretics resulted in a 2.90-fold (aOR: 2.90; 95 %CI 1.47–5.70) and 12.68-fold (aOR: 12.68; 95 %CI 6.15–26.12) risk, respectively. The highest risk occurred with triple combination (aOR: 29.22; 95 %CI 12.82–66.64). ConclusionsNSAIDs, including both non-selective NSAIDs and COX2 inhibitors, elevate the risk of AKI. Increased AKI risk is linked to using multiple NSAIDs, the parenteral dosage form, and higher cumulative doses. Dual combination of RAS blockade with NSAIDs or diuretics with NSAIDs, as well as triple therapy, heightens the risk, with the latter associated with the highest risk of AKI.

Adenomyotic Lesions Are Induced in the Mouse Uterus after Exposure to NSAID and EE2 Mixtures at Environmental Doses.

The aim of this study was to assess the long-term effect of exposure to environmentally relevant doses of non-steroidal anti-inflammatory drugs (NSAIDs; ibuprofen, and diclofenac) and 17β-ethinylestradiol (EE2) on the mouse uterus. NSAID-EE2 mixtures were administered in the drinking water from gestational day 8 until 8 weeks post-birth (i.e., during embryo development, lactation, puberty, and sexual maturity). The incidence of adenomyosis lesions (presence of endometrial glands in the inner myometrium) increased up to 60% in the uterus of 8-week-old exposed females (F1) and to 85% in F2 females (exposed father). Histological analysis revealed aberrant proliferation and apoptosis, vacuolization of epithelial cells, and increased incidence of abnormal glands in the luminal and glandular epithelium in F1 and F2 uteri. Moreover, myofibroblast proportion (alpha-smooth muscle actin (α-SMA) expression analysis) and collagen expression (Picrosirius red stain; a fibrosis hallmark) were increased in F1 and F2 endometrium. Connexin-43 was aberrantly distributed in the endometrial stroma and glands of F1 and F2 uteri. Conversely, uterine 17β-estradiol and progesterone levels were not affected in F1 and F2 females. These findings demonstrated that in mice, chronic exposure to NSAID and EE2 mixtures at environmental doses intergenerationally affects uterine physiology, particularly the endometrium. It may serve as a model to study the pathophysiology of human adenomyosis.

The role of transcutaneous electrical nerve stimulation for menstrual pain relief: A randomized control trial.

Abdominal pain due to menses (primary dysmenorrhea) is an extremely pervasive and debilitating symptom affecting up to 90% of menstruating individuals. The objective of this randomized control trial was to investigate the effect of a commercial transcutaneous electrical nerve stimulation unit, Therabody PowerDot® (Therabody Inc., Los Angeles) on dysmenorrhea compared with non-steroidal anti-inflammatory drug use. This was a randomized cross-over study. A total of 47 participants agreed to participate in the study, with 34 completing it. Participants completed treatments across three consecutive menstrual cycles in randomized order: single-unit transcutaneous electrical nerve stimulation (Uno), dual unit transcutaneous electrical nerve stimulation (Duo), and non-steroidal anti-inflammatory drug use (Control). Upon onset of dysmenorrhea, participants applied transcutaneous electrical nerve stimulation to their abdomen for a minimum of 30 min. Control participants were instructed to take non-steroidal anti-inflammatory drugs as needed. Surveys were used to record pain before and after treatment. We hypothesized that the PowerDot would decrease self-reported pain scores, and decrease non-steroidal anti-inflammatory drug consumption during menses. Participants experienced a statistically and clinically significant reduction in pain during the Control (-3.52 ± 1.9), Uno (-2.10 ± 1.6), and Duo (-2.19 ± 1.7) cycles (p < 0.001). The doses of non-steroidal anti-inflammatory drugs consumed during the Control cycle (3.5 ± 2.6), was significantly different as compared with that of Uno (1.5 ± 3.0), or Duo (1.1 ± 2.6) (p = 0.004). Use of a commercial transcutaneous electrical nerve stimulation unit results in significant decrease in pain. Although not as robust as the relief in pain induced by non-steroidal anti-inflammatory drugs, the adverse events of transcutaneous electrical nerve stimulation are minimal in comparison. Therefore, transcutaneous electrical nerve stimulation appears to be a viable alternative to pain relief from dysmenorrhea. NCT05178589.

Modern possibilities of therapy of nonspecific pain in the lower back

Aim. To evaluate the effectiveness of combination therapy for low back pain (LBP) associated with spinal osteoarthritis (OA) using the Symptomatic Slow Acting Drugs for OsteoArthritis (SYSADOA) group drug Ambene® Bio.Materials and methods. The study included 30 patients with LBP aged 40 to 65 years. Various scales and questionnaires were used to assess the patients’ condition. All patients received Ambene® Bio 2.0 ml intramuscularly every other day for a total course of 10 injections. Some patients with severe pain continued to receive previously prescribed non-steroidal anti-inflammatory drugs (NSAIDs). After completing the course of treatment with Ambene® Bio, the overall effect of the therapy, changes in individual need for NSAIDs and the presence of adverse events were assessed.Results. All patients sought medical care due to exacerbation of chronic LBP. X-ray examination of the lumbosacral spine revealed degenerative-dystrophic changes in the vertebral-motor segments of the lumbar spine in all patients and in some patients – in the sacroiliac joints. The treatment showed positive dynamics in 27 (90 %) patients in the form of pain reduction not only in the lower back but also in peripheral joints. Of the 13 patients initially receiving NSAIDs, 7 (53.8 %) reduced the daily dose of the drug, and 3 (23.1 %) were able to stop taking NSAIDs. In 3 (23.1 %) cases, the initial NSAID dosage remained unchanged. Monotherapy with Ambene® Bio was received by 17 (56.7 %) patients. All patients expressed satisfaction with the treatment, of which 18 (60 %) rated the result as “excellent”, 7 (23.4 %) as “good” and 5 (16.6 %) as “satisfactory”.Conclusion. In all patients, therapy with Ambene® Bio, both in mono mode and in in combination with NSAIDs, had a positive effect, which was expressed in the reduction of the intensity of LBP on visual analog scale, improvement of peripheral joint function. In 7 (23.3 %) patients pain reduction was observed after the second injection of the drug (“the effect of the first dose”). In other cases the pain regressed later, but also within the course of treatment. All patients showed high adherence to therapy, which was explained by the rapid onset of the effect. The results of the study allow us to recommend Ambene® Bio for the treatment of LBP associated with spinal OA and within generalized OA, including patients with comorbid conditions.

Patients with ischaemic heart disease and non-steroidal anti-inflammatory drugs dosing — recommendations and real-life clinical setting

Patients with ischaemic heart disease and non-steroidal anti-inflammatory drugs dosing — recommendations and real-life clinical setting

Acute medications' intake for migraine: a one-year report in patients undergoing first evaluation at a third level Italian headache center.

Headache disorders, particularly primary headaches like migraine and tension-type headache, still remain underdiagnosed and undertreated despite their high prevalence and significant impact on quality of life. In recent years, several specific medications targeting key pathways in the pathophysiology of migraine have been developed. Despite this advancement, numerous studies indicate that non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics remain the most commonly used drugs. This study focused on the use of NSAIDs and simple analgesics as acute treatments for migraine among patients at a tertiary headache center. A retrospective observational study was conducted at the Fondazione Policlinico Universitario Campus Bio-Medico throughout 2022. Data were collected on the type and frequency of headaches, the usage and dosage of NSAIDs and other medications, and changes in their use at follow-up visits. Statistical analyses were performed to evaluate the efficacy and determinants of NSAID consumption and headache frequency changes. Two hundred and eightythree patients diagnosed with migraine undergoing their first examination at our center were enrolled. Initially, 58.7% of patients used NSAIDs or simple analgesics, which decreased to 46.6% 3 months after, while triptan use increased from 65.1 to 72.8%. Changes in prophylactic therapies were significantly associated with a decrease in NSAID intake (W = 834.000, p = 0.004) and in headache frequency (W = 5960.5, p = 0.003). Specifically, the addition of topiramate or amitriptyline was associated with a reduction in NSAID use and headache frequency. Even pain freedom after the intake of NSAIDs improved from 55.2 to 79.4% of cases at follow-up. The study highlights the importance of appropriate diagnosis and tailored treatment strategies in the management of primary headaches. It underscores the need for specialized care to enhance treatment efficacy and patient outcomes, demonstrating that adjustments in prophylactic therapy can significantly reduce NSAID intake and improve headache care. This reinforces the role of tertiary headache centers in providing specialized care that can adapt treatments to individual patient needs and improve overall headache management.

Etanercept induced erectile dysfunction

Background: Ankylosing spondylitis (AS) is a chronic inflammatory disease of the axial spine. Etanercept is a Tumor necrosis factor-alpha inhibitor (anti-TNF) that is widely used in the treatment of AS. The most common side effects of etanercept are infection, rash, and injection site reaction. Here, we reported an adverse event probably associated with etanercept. Case Presentation: A 30-year-old male patient with AS initiated etanercept due to uncontrolled back pain despite adequate doses of non-steroidal anti-inflammatory drugs. He developed erectile dysfunction (ED) within 1 month of etanercept treatment. ED disappeared after switching to secukinumab. Conclusion: There is limited data on the potential effects of anti-TNF on sexual function. ED might be a rare side effect of etanercept that resolves upon discontinuation of the drug. Secukinumab might be considered as an option in case of etanercept induced ED. Even though ED is not a life-threatening side effect, switching medications could significantly improve patients&amp;apos; quality of life.

The effect of nonsteroidal anti-inflammatory drug use on soft tissue and bone healing in the knee: a systematic review.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to mitigate pain and inflammation associated with musculoskeletal conditions; however, there is conflicting data on the adverse effects of these drugs on tissue and bone healing. The objective of this study was to investigate the effect of NSAIDs on the healing of knee, soft tissue, and bone. A systematic literature search was conducted across PubMed/MEDLINE, Excerpta Medical Database (Embase)/Ovid, and the Cochrane Central Register of Controlled Trials databases. Clinical, animal, and in vitro studies on the effect of NSAIDs on knee healing were included. Risk of bias assessment was performed using the Cochrane bias assessment tool and Methodological Index for Non-Randomized Studies scoring system for included clinical studies, and the Systematic Review Center for Laboratory Animal Experimentation assessment tool for all included animal studies. General study population characteristics, interventions used, NSAIDs utilized, outcome measures, and study results were analyzed using descriptive statistics. Fifteen articles met the inclusion criteria. Of the 15 studies, there were three clinical, ten animal, and two in vitro studies. In clinical studies, nonselective cyclooxygenase (COX) inhibitors and selective COX-2 inhibitors did not cause a significant increase in failure of anterior cruciate ligament (ACL) reconstructions or meniscal repairs with NSAID administration pre-, peri-, or post-operatively in comparison to placebo or no NSAID administration. Among animal studies assessing COX-2 inhibitor effects on soft tissue, healing was impaired (2/4), delayed but unaffected (1/4), or unaffected (1/4). In animal studies assessing COX-1 inhibitors, ligament healing was either increased (1/4), unaffected (2/4), or impaired (1/4). Meanwhile, administration of non-selective COX inhibitors in animals did not affect soft tissue (3/3) and cartilage (1/1) healing. Two in vitro studies identified a negative outcome on patellar tendon and ACL cell proliferation or viability after non-selective COX inhibition and variable results after selective COX-2 inhibition. Animal studies on postoperative NSAID use after knee surgery suggest that administration of selective and nonselective COX-2 inhibitors may impair healing of soft tissue, bone and tendon-to-bone; however, further clinical studies are needed to better characterize dose and duration dependent risks of NSAIDs.

Use of non-steroidal anti-inflammatory drugs in renal transplant patients: A retrospective study.

Renal transplanted patients are often prescribed non-steroidal anti-inflammatory drugs (NSAIDs) for analgesic purposes. Considering the dearth of data, we carried out the present study to evaluate the use of various NSAIDs and the incidence of acute kidney injury (AKI) in transplant patients. A retrospective study amongst renal transplant patients prescribed at least one dose of NSAID was carried between January and December 2020 at the Department of Nephrology, Salmaniya Medical Complex, Kingdom of Bahrain. The patients' demographic details, serum creatinine values, and drug-related details were obtained. The Kidney Disease Improving Global Outcomes (KDIGO) criteria were used for defining AKI. Eighty-seven patients were included. Forty-three patients were prescribed diclofenac, 60 received ibuprofen, six received indomethacin, 10 were administered mefenamic acid, and 11 received naproxen. Due to multiple courses of NSAID prescription, a total of 70 prescriptions were identified for diclofenac, 80 for ibuprofen, six for indomethacin, 11 for mefenamic acid, and 16 for naproxen. No significant differences were observed in the absolute (p =0.08) and percent changes in serum creatinine (p =0.1) between the NSAIDs. Twenty-eight (15.2%) courses of NSAID therapy met the KDIGO criteria for AKI. Age (OR: 1.1, 95% CI: 1.007, 1.2; p =0.02), concomitant everolimus (OR: 483, 95% CI: 4.3, 54407; p =0.01), and mycophenolate + cyclosporine + azathioprine (OR: 63.4E+006, 95% CI: 203.2157 to 19.8E+012; p =0.005) administration were observed with significant risk of NSAID-induced AKI. We observed possible NSAID-induced AKI to an extent of around 15.2% in our renal transplant patients. No significant differences were observed in the incidence of AKI between various NSAIDs and none of them had either graft failure or death.

Intergenerational effects on fertility in male and female mice after chronic exposure to environmental doses of NSAIDs and 17α-ethinylestradiol mixtures

Non-steroidal anti-inflammatory drugs (NSAIDs) and 17α-ethinylestradiol (EE2) are extensively used in human and veterinary medicine. Due to their partial removal by wastewater treatment plants, they are frequent environmental contaminants, particularly in drinking water. Here, we investigated the adverse outcomes of chronic exposure to mixtures of NSAIDs (ibuprofen, 2hydroxy-ibuprofen, diclofenac) and EE2 at two environmentally relevant doses in drinking water, on the reproductive organ development and fertility in F1-exposed male and female mice and in their F2 offspring. In male and female F1 mice, which were exposed to these mixtures, reproductive organ maturation, estrous cyclicity, and spermiogenesis were altered. These defects were observed also in F2 animals, in addition to some specific sperm parameter alterations in F2 males. Transcriptomic analysis revealed significant changes in gene expression patterns and associated pathways implicated in testis and ovarian physiology. Chronic exposure of mice to NSAID and EE2 mixtures at environmental doses intergenerationally affected male and female fertility (i.e. total number of pups and time between litters). Our study provides new insights into the adverse effects of these pharmaceuticals on the reproductive health and will facilitate the implementation of a future regulatory environmental risk assessment of NSAIDs and EE2 for human health.

Post-Operative Analgesia and Enhanced Recovery after Pecs 1 and Pecs 2 Blocks in Patients Undergoing Modified Radical Mastectomy/Breast-Conserving Surgery with Axillary Lymph Nodal Clearance

Background Patients undergoing modified radical mastectomy (MRM)/breast-conserving surgery (BCS) with axillary nodal clearance experience significant post-operative pain, resulting in immobilization and increased usage of analgesics. These factors in turn result in delayed discharge. The pecs 1 and pecs 2 blocks have proven to be of significant benefit in relieving post-operative pain in such patients. Objectives A case series was performed at our institute to note the effects of pecs 1 and pecs 2 blocks on post-operative opioid use, early mobilization of the upper limbs, decreased incidence of early post-operative limb swelling and enhanced recovery after surgery. Material and Methods We included six patients who underwent BCS with axillary lymph node dissection/MRM wherein intraoperative pecs 1 and pecs 2 blocks were used. Patients were given pecs 1 and 2 blocks with 10+20 mL 0.25% injection of bupivacaine under ultrasound guidance after induction. Results In our study, opioids were completely avoided and it was seen that post-operative pain was adequately controlled with single doses of non-steroidal anti-inflammatory drugs if patients received intra-operative pecs 1 and 2 blocks. The pain control was rather sustained and adequate for the institution of early post-operative physiotherapy and thus early discharge and enhancing recovery after surgery. Conclusion Post-operative analgesia provided by pecs 1 and 2 blocks resulted in adequate and sustained pain control for early institution of upper limb physiotherapy and mobilization of patients after MRM/BCS with axillary lymph node dissection, which subsequently results in decreased incidence of early post-operative oedema of limb on operated side and early recovery after surgery.

Cat’s Claw Nutrients for Medical Treatments

Uncaria tomentosa (Willd. ex Schult.) DC is commonly known as cat’s claw that is derived from the Spanish word Uña de Gato that identifies the small, curved-back thorns on the stem at the leaf junction. It is a tropical medicinal vine of the Rubiaceae family that is widely distributed in the Amazon rainforest and other areas of South and Central America. Cat's claw, which is scientifically known as Uncaria tomentosa, has been historically used to treat and prevent inflammatory disorders, particularly osteoarthritis. Traditionally, it has been used to treat chronic viral infections, bacterial infections, numerous inflammatory and immunological disorders, asthma, dysentery, cancers, arthritis, and as a birth control agent. Nutraceuticals, including food or products containing cat’s claw, can be used to prevent and modify symptoms in osteoarthritis patients. So, cat’s claw is possibly effective in reducing the pain in patient’s joints. U. tomentosa is a potent complimentary herb for treating most parasites. Various chemical constituents are reported from the extracts of U. tomentosa along with their biological activities. It is worth noting that more than 50 phytochemical molecules have been identified and isolated from U. tomentosa, some of them are considered new to that species. It also was used for the treatment of various ailments including abscesses, urinary tract infections, contraception, rheumatism, and weakness. Additionally, it was used as a treatment option for mental disorders (anxiety). The preclinical assessment revealed that the cat’s claw defends towards various oxidative stresses, involving peroxynitrite that has been included in arthritis and other chronic inflammatory diseases along with inhibiting acute or chronic gastritis caused by high doses of nonsteroidal anti-inflammatory drugs (NSAIDs). U. tomentosa aqueous extract was used to protect against oxidative stress in human erythrocytes and relieve chronic intestinal inflammation. Cat’s claw has antitumor and immunostimulatory effects because of its oxindole alkaloids content. Anti proliferative effect of U. tomentosa against several cancer cell lines, namely cervical carcinoma, osteosarcoma, and breast cancer were documented. U. tomentosa hot water extract prevents inflammatory responses as well as tumor cell proliferation by inhibiting the transcriptional regulator nuclear factor kappa beta (NF-B) activation without interfering with interleukin-2 (IL-2) production or IL-2 receptor signaling. Medical technologists documented the ant proliferative effect of cat’s claw extracts against several cell lines, including glioma, premyelocytic leukemia, MCF7 breast cancer, acute lymphoblastic leukaemia, and neuroblastoma.
