Single-Blind Randomized Controlled Trial: Comparative Efficacy of Dark Chocolate, Coconut Water, and Ibuprofen in Managing Primary Dysmenorrhea.

Dysmenorrhea, the pain experienced by women during menstruation, affects a significant proportion of women worldwide and often leads to decreased productivity. Various pharmacological and non-pharmacological treatments are available for pain relief, but information on their effectiveness, particularly regarding green coconut water, dark chocolate, and Ibuprofen, remains limited. This study aimed to compare the effectiveness of green coconut water, dark chocolate bars, and Ibuprofen in reducing the intensity of primary dysmenorrhea. In this research, a randomized controlled trial with a quantitative design was conducted, involving 45 participants randomly assigned to receive 330 mL of green coconut water, 35 g of 70% dark chocolate, or 400 mg Ibuprofen. The interventions were administered on the first day of menstruation when dysmenorrhea symptoms typically occur in subjects. This study used a single-dose approach to evaluate the immediate impact of each treatment. The subjects were instructed to consume the given interventional product within 15 min. The pain intensity was measured using a Numeric Rating Scale before the intervention and 2 h after the subjects finished consuming the interventional product. The multivariate Kruskal-Wallis test revealed a significant difference in effectiveness among the three interventions (p < 0.05). The study found that Ibuprofen was the most effective intervention compared to the other interventions. These findings contribute to understanding the treatment options for primary dysmenorrhea and emphasize the efficacy of Ibuprofen (trial registration: ClinicalTrials.gov: NCT05971186).

Hypersensitivity to Non-Steroidal Anti-Inflammatory Drugs on a pediatric Portuguese cohort.

Summary: Background. Non-steroidal anti-inflammatory drugs (NSAID)/analgesics (paracetamol) are among the most common causes of drug hypersensitivity reactions in children, with a reported prevalence of around 0.3% in the pediatric population. Paracetamol and ibuprofen are the most commonly reported culprits in the pediatric population. Our objective was to describe the allergy workup to NSAID/paracetamol of a pediatric population monitored in an allergy outpatient clinic. Methods. Retrospective observational study by consulting the medical records of patients evaluated in a pediatric outpatient clinic with history of NSAID/paracetamol, between January 2016 to August 2022. Results. A total of 43 patients have been evaluated for NSAID/paracetamol suspected allergy: 53.5% females, mean age of 9.8 ± 5.1 years, 47.7% atopic. The drugs reported as culprits were: ibuprofen (75.6%), paracetamol (17.8%), metamizole (4.4%) and naproxen (2.2%) and clinical manifestations were mainly urticaria/angioedema and maculopapular exanthema. Skin tests were performed in 7 patients: paracetamol (n = 5) and metamizole (n = 2), which were all negative. Fourty-six drug provocation tests were performed: 28 with the culprit drug and 18 with an alternative one; only 2 were positive (ibuprofen - culprit NSAID group): one immediate periorbital angioedema and one delayed lip edema with oropharyngeal tightness. Conclusions. The investigation of allergy to NSAID/paracetamol in children remains a challenge. In our population, ibuprofen was the most common NSAID reported. There were only 2 (4.3%) mild reactions on DPT. We could allow the use of the culprit NSAID/analgesic in 11 patients and an alternative one in 9 patients. This study highlights the importance of DPT in children for a correct diagnosis of NSAID hypersensitivity and selection of an alternative drug.

An updated perspective on diagnostics and treatment of idiopathic granulomatous mastitis.

AIM: To present our experiences with the anti-inflammatory treatment of idiopathic granulomatous mastitis (IGM) and highlight the imaging and anamnestic specifics of its diagnosis. METHODS: Patients with acute inflammatory breast disease underwent ultrasound examination followed by a collection of anamnestic data, and histological analysis of the process was performed using core-cut bio psy, confirming IGM. Subsequently, anti-inflammatory treatment was administered, consisting of a combination of colchicine, vitamin E, and local compresses made from an infusion of Plantago lanceolata. We also recorded any additional treatments administered extra muros prior to histological analysis (such as antibio tics, surgical intervention, and time from onset of symptoms to confirmation of diagnosis). We analyzed the effect of the anti-inflammatory treatment administered, including the onset of improvement, adverse effects, recurrences, and duration of treatment required for symptom resolution. RESULTS: Between 2016 and 2022, we diagnosed and histologically confirmed IGM in 53 patients through bio psy. Of these, 45 (84.9%) underwent the anti-inflammatory treatment we proposed, while eight (15.1%) opted for a different form of therapy. Currently, 27 patients (60%) are without treatment and clinical manifestations. The average duration of treatment was 34 months, and improvement in the clinical condition was observed within 2-8 weeks (average of 3 months). Four patients (14.81%) reported dyspepsia as an adverse effect. Recurrence occurred in five patients (18.52%) after 1-36 months (average of 7 months). Patients (22, 81.48%) who completed the treatment are without difficulties for 3-70 months (average of 34 months). The remaining 18 patients (40%) are currently undergoing treatment, lasting 3-41 months (average of 19 months). CONCLUSION: Anti-inflammatory treatment with colchicine, along with supportive therapy (compresses made from an infusion of Plantago lanceolata and vitamin E), represents a promising trend in the therapy of IGM, with minimal adverse effects.

Stress- and drug-induced neuroimmune signaling as a therapeutic target for comorbid anxiety and substance use disorders.

Stress and substance use disorders remain two of the most highly prevalent psychiatric conditions and are often comorbid. While individually these conditions have a debilitating impact on the patient and a high cost to society, the symptomology and treatment outcomes are further exacerbated when they occur together. As such, there are few effective treatment options for these patients, and recent investigation has sought to determine the neural processes underlying the co-occurrence of these disorders to identify novel treatment targets. One such mechanism that has been linked to stress- and addiction-related conditions is neuroimmune signaling. Increases in inflammatory factors across the brain have been heavily implicated in the etiology of these disorders, and this review seeks to determine the nature of this relationship. According to the "dual-hit" hypothesis, also referred to as neuroimmune priming, prior exposure to either stress or drugs of abuse can sensitize the neuroimmune system to be hyperresponsive when exposed to these insults in the future. This review completes an examination of the literature surrounding stress-induced increases in inflammation across clinical and preclinical studies along with a summarization of the evidence regarding drug-induced alterations in inflammatory factors. These changes in neuroimmune profiles are also discussed within the context of their impact on the neural circuitry responsible for stress responsiveness and addictive behaviors. Further, this review explores the connection between neuroimmune signaling and susceptibility to these conditions and highlights the anti-inflammatory pharmacotherapies that may be used for the treatment of stress and substance use disorders.

Effect of interleukin-6, -17, -21, -22, and -23 and STAT3 on signal transduction pathways and their inhibition in autoimmune arthritis.

Rheumatic diseases are complex autoimmune diseases which include among others rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), and psoriatic arthritis (PsA). These diseases are characterized by prolonged and increased secretion of inflammatory factors, eventually leading to inflammation. This is often accompanied by persistent pain and stiffness in the joint and finally bone destruction and osteoporosis. These diseases can occur at any age, regardless of gender or origin. Autoimmune arthritis is admittedly associated with long-term treatment, and discontinuation of medication is associated with unavoidable relapse. Therefore, it is important to detect the disease at an early stage and apply appropriate preventative measures. During inflammation, pro-inflammatory factors such as interleukins (IL)-6, -17, -21, -22, and -23 are secreted, while anti-inflammatory factors including IL-10 are downregulated. Research conducted over the past several years has focused on inhibiting inflammatory pathways and activating anti-inflammatory factors to improve the quality of life of people with rheumatic diseases. The aim of this paper is to review current knowledge on stimulatory and inhibitory pathways involving the signal transducer and activator of transcription 3 (STAT3). STAT3 has been shown to be one of the crucial factors involved in inflammation and is directly linked with other pro-inflammatory factors and thus is a target of current research on rheumatoid diseases.

Microalga Scenedesmus bajacalifornicus BBKLP-07, a new source of bioactive compounds with in vitro pharmacological applications.

Microalgae are photosynthetic eukaryotes which are primary producers in the food chain and also excellent sources for bioactive compounds such as alkaloids, flavonoids, phenols, saponins and other fine chemicals. In the present study, the microalga Scenedesmus bajacalifornicus BBKLP-07 was subjected to soxhlet extraction using solvents like chloroform, acetone, ethanol, methanol and aqueous solvents. All the solvents were tested for the presence of phytochemical constituents such as alkaloids, flavonoids, glycosides, phenols, lignin's, saponins, sterols, tannins, anthraquinone and reducing sugar using the standard procedures. Furthermore, all the crude extracts were subjected to antidiabetic, antioxidant, anti-inflammatory and antimicrobial activities. Antidiabetic activity of the microalgal extracts was observed maximum in Aqueous extract. Methanolic extracts have shown maximum antioxidant activity and chloroform extracts have exhibited highest anti-inflammatory effects. Antimicrobial activities were tested against E.coli, S, typhi, C.perfringens and B.subtilis bacteria and fungi A.niger, and C. albicans. Therefore, the green microalga Scenedesmus bajacalifornicus BBKLP-07 is a rich source of biological active compounds and nutraceuticals and can be exploited for commercial applications.

Anti-inflammatory diterpenes from the fruits of Vitex trifolia L. var. simplicifolia Cham.

Two new labdane-type diterpenes, named viterotulin C (1) and vitexilactone D (2), together with five known diterpenes (3-7), were isolated from the fruits of Vitex trifolia L. var. simplicifolia Cham. Their structures were elucidated by detailed analysis of spectroscopic data. All the compounds were evaluated for their inhibitory effects on nuclear factor-kappa B (NF-κB) pathway in HEK 293 cell line. These compounds presented inhibition on TNF-α-induced NF-κB activation, with inhibition rates ranging from 42.52 ± 10.69% to 68.86 ± 10.76% at the concentration of 50 µM.

Non-Antimicrobial Drugs: Etodolac as a Possible Antimicrobial or Adjuvant Agent Against ESKAPE Pathogens.

INTRODUCTION: Multiple-drug resistant bacteria are emerging exponentially in healthcare units, threatening public health and requiring novel therapeutic approaches. In 2017, World Health Organization published a list that frames antimicrobial resistant bacteria into priority levels for research of novel drugs to fight them. METHODS & MATERIALS: Antimicrobial resistant ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter sp.) and Enterococcus faecalis and Escherichia coli pathogens are present in this list. Representative isolates of each species were used to test the Antibacterial and anti-biofilm formation activities of Etodolac (a Non-Steroidal Anti-Inflammatory Drug, NSAID) at 10 and 1 mM using a broth microdilution technique. RESULTS & DISCUSSION: Statistically significant (p< 0,05) results were observed against all tested gram-positives, particularly anti-biofilm activity against E. faecium. Etodolac had an almost null influence on tested gram-negatives, with the exception of one A. baumannii clinical isolate regarding biofilm formation inhibition. Observed differences deserve further analysis and prospection of the involved mechanisms, to unravel possible novel bacterial targets for drug development. Similar work with other NSAID's may also be worth exploring to ascertain novel therapeutic applications for these drugs, particularly regarding biofilm formation inhibition, per si or as adjuvants of current antibiotherapy, mainly against gram-positives, as suggested by present work. CONCLUSION: Already approved drugs in terms of pharmacokinetics and safety may deploy faster solutions for antimicrobial therapy against priority pathogens. Current work intends to bring attention to that possibility, particularly regarding NSAIDs, anti-biofilm formation and top priority pathogens.

Antioxidant and anti-inflammatory activities of freeze-dried grapefruit phenolics as affected by gum arabic and bamboo fibre addition and microwave pretreatment.

BACKGROUND: Recent epidemiological studies have suggested that phenolic compounds present in grapefruit play an important role in the bioactive properties of this fruit. However, the consumption of fresh grapefruit is low. Freeze-dried powdered grapefruit can be an alternative to promote this fruit consumption. To improve the quality and stability of the powdered fruit, encapsulating and anticaking agents can be added. In the present study, different grapefruit powders obtained by freeze-drying with the addition of gum arabic (1.27 g per 100 g) and bamboo fibre (0.76 g per 100 g) with and without a pre-drying microwave treatment were compared with the fresh and freeze-dried fruit with no carriers added, aiming to evaluate the effect of these preservation processes on phenolics content and on its antioxidant [1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and ferric reducing ability of plasma (FRAP)] and anti-inflamatory (evaluated in RAW 264.7 macrophages) capacities. RESULTS: Freeze-drying and gum arabic and bamboo fibre addition significantly increased total phenolics, as well as the antioxidant and anti-inflammatory activities (by inhibiting nitric oxide production of lipopolysaccharide activated RAW 264.7 macrophages), of grapefruit. An additional increase in these parameters was obtained with microwave pretreatment before freeze-drying. CONCLUSIONS: The combined addition of gum arabic and bamboo fibre to grapefruit puree and the application of a microwave pretreatment improve the functional properties of the fruit without showing cytotoxicity in vitro. © 2017 Society of Chemical Industry.

Ibuprofen - a Safe Analgesic During Cardiac Surgery Recovery? A Randomized Controlled Trial.

INTRODUCTION: Postoperative pain-management with non-steroid anti-inflammatory drugs has been controversial, due to related side-effects. We investigated whether there was a significant difference between an oxycodone-based pain-management regimen versus a slow-release ibuprofen based regimen, in a short term post-cardiac surgery setting. Particular attention was given to the rate of myocardial infarction, sternal healing, gastro-intestinal complications, renal failure and all-cause mortality. METHODS: This was a single-centre, open label parallel design randomised controlled study. Patients, who were undergoing cardiac surgery for the first time, were randomly allocated either to a regimen of slow-release oxycodone (10 mg twice daily) or slow-release ibuprofen (800 mg twice daily) combined with lansoprazole. Data relating to blood-tests, angiographies, surgical details and administered medicine were obtained from patient records. The follow-up period was 1 to 37 months (median 25 months). RESULTS: One hundred eighty-two patients were included in the trial and available for intention to treat analysis. There were no significant difference between the groups (P>0.05) in the rates of sternal healing, postoperative myocardial infarction or gastrointestinal bleeding. The preoperative levels of creatinine were found to increase by 100% in nine patients (9.6%) in the ibuprofen group, resulting in an acute renal injury (in accordance with the RIFLE-criteria). Eight of these patients returned to normal renal function within 14 days. The levels of creatinine in patients in the oxycodone group were not found to increase to the same magnitude. CONCLUSION: The results of this study suggest that patients treated postoperatively, following cardiac surgery, are at no greater risk of harm if short term slow release ibuprofen combined with lansoprazole treatment is used when compared to an oxycodone based regimen. Renal function should, however, be closely monitored and in the event of any decrease in renal function ibuprofen must be discontinued.

Anti-inflammatory drugs and uterine cervical cancer cells: Antineoplastic effect of meclofenamic acid.

Uterine cervical cancer (UCC) is one of the main causes of cancer-associated mortality in women. Inflammation has been identified as an important component of this neoplasia; in this context, anti-inflammatory drugs represent possible prophylactic and/or therapeutic alternatives that require further investigation. Anti-inflammatory drugs are common and each one may exhibit a different antineoplastic effect. As a result, the present study investigated different anti-inflammatory models of UCC in vitro and in vivo. Celecoxib, sulindac, nimesulide, dexamethasone, meclofenamic acid, flufenamic acid and mefenamic acid were tested in UCC HeLa, VIPA, INBL and SiHa cell lines. The cytotoxicity of the drugs was evaluated in vitro. Celecoxib, sulindac, nimesulide, mefenamic acid and flufenamic acid presented with slight to moderate toxicity (10-40% of cell death corresponding to 100 µM) in certain cell lines, while meclofenamic acid exhibited significant cytotoxicity in all essayed cell lines (50-90% of cell death corresponding to 100 µM). The meclofenamic acid was tested in murine models (immunodeficient and immunocompetent) of UCC, which manifested a significant reduction in tumor growth and increased mouse survival. It was demonstrated that of the evaluated anti-inflammatory drugs, meclofenamic acid was the most cytotoxic, with a significant antitumor effect in murine models. Subsequent studies are necessary to evaluate the clinical utility of this drug.

Therapeutic potential of Polyalthia cerasoides stem bark extracts against oxidative stress and nociception.

BACKGROUND: Polyalthia cerasoides is a medicinal plant known for its ethnopharmacological importance. Despite this, investigation related to its therapeutic benefit is still unexplored. AIM: To evaluate the stem bark extracts of Polyalthia cerasoides for pharmacological activities relating to inflammation, nociception and oxidative stress using in vivo and in vitro models. MATERIALS AND METHODS: Pet ether, ethyl acetate and chloroform fractions of the stem bark were evaluated for anti-inflammatory activity by carrageenan-induced hind paw edema in rats. Anti-nociceptive activity in mice was assessed using thermally and chemically induced analgesic models. The free radical quenching potential of the extracts was initially analyzed using the in vitro DPPH photometric assay, Hydroxyl radical scavenging and Lipid Peroxidation assays. Then modulatory effect of the extracts on in vivo antioxidant system was evaluated by carbon tetrachloride induced hepatotoxicity and subsequent measurements of antioxidant enzymes such as Superoxide dismutase, Catalase and Peroxidase from the liver homogenate. RESULTS: Among the tested fractions, ethyl acetate extract had substantially inhibited the inflammation by 68.5% that was induced by subcutaneous carrageenan injection whereas pet ether and chloroform extract showed only minimal inhibitory effect. Investigation of the anti-nociceptive activity revealed that the ethyl acetate fractions had significantly repressed the algesia in both the analgesic experimental models. In vitro and in vivo individual antioxidant assays demonstrated that the ethyl acetate fraction has strong free radical quenching potential which also restores the endogenous hepatic enzymes. CONCLUSION: The ethyl acetate fraction enriched with flavinoids and steroids from Polyalthia cerasoides stem bark has potent bioactivity to combat inflammation, ROS and pain. This needs further characterization for potential therapeutic applications.

Efecto antiinflamatorio y antioxidante del extracto hidroalcohólico de Petiveria alliacea

Los radicales libres y el daño oxidativo están relacionados con la muerte celular, siendo la peroxidación lipídica un mecanismo que lleva a la destrucción oxidativa de la membrana celular. Además, en procesos inflamatorios, uno de los primeros estadios es la permeabilidad vascular incrementada (formación del edema) seguido de la extravasación de los fluídos, migración de leucocitos al sitio dañado y liberación de proteínas pro-inflamatorias. Evaluamos el efecto antioxidante y antiinflamatorio para Petiveria alliacea “mucura”. Para el efecto antioxidante, se evaluó la formación de especies reactivas al ácido tiobarbitúrico como indicador de la peroxidación lipídica. Dosis 200mg/mL de Petiveria alliacea disminuyó significativamente en un 42% los niveles de MDA comparado con el agua (control negativo). En la evaluación antiinflamatoria, se indujo la inflamación por inyección de carragenina (solución al 1%), en la parte subplantar de ratones y en la “bolsa de aire subcutánea” de ratas para la inflamación aguda y crónica respectivamente. En la evaluación antiinflamatoria hay una máxima reducción del edema en un 23,26% a las 4 horas del tratamiento. Para la inflamación crónica hay una reducción del 25,9% y 29,5% del peso y volumen del exudado extraído, respectivamente, así como una reducción del 24% de peso de tejido fibroso. Estos resultados evidencian efecto antioxidante y antiinflamatorio de Petiveria alliacea

The free radicals and the oxidative damage are related with cellular death, with the lipid peroxidation being a mechanism that leads to oxidative destruction of the cellular membrane. Furthermore, in inflammatory process, one of the first stages is the incremented vascular permeability (formation of the oedema) followed with the extravasation of the fluids, migration of the leucocytes to the damaged site and release of pro-inflammatory proteins. Was evaluated antioxidants and anti-inflammatory of Petiveria alliacea “mucura”. For antioxidants effect, was evaluated formation of thiobarituric acid reactive substances as indicator of lipid peroxidation. Doses 200 mg/mL of Petiveria alliacea decrease significatly in 42% levels of MDA compared to water (negative control). In the antiinflammatory evaluation, inflammation was analyzed in the carrageenan-induced paw oedema test in mice (solution to 1 %) and in the "carrageenan-induced air-pouch formation" of rates for acute and chronic inflammation respectively. In anti-inflammatory evaluation there is a significant reduction of the edema in 23.26% at 4hrs at the treatment. For chronic inflammation there is a reduction of 25.9% and 29.5% of the weight and volume of exuded extract respectively, as well as a reduction of 24% of weight of fibrous tissue. These results demonstrate antioxidant and anti-inflammatory effects of Petiveria alliacea

Sangrado digestivo alto no varicoso: Asociado a aines en el Servicio de Gastroenterología del Hospital del Niño. 1995-2008

El sangrado digestivo alto no varicoso constituye una de las principales formas de presentación de la gastroenteropatía por antiinflamatorios no esteroideos (AINES). La relación entre AINES y lesión gastrointestinal esta bien establecida; sin embargo la mayor parte de la información bibliográfica disponible deriva de estudios realizados en adultos. De igual forma, los factores de riesgo establecidos para esta patología se circunscriben a la edad adulta; no obstante es de suponer que las características conductuales y fisiológicas de los niños podrían sugerir factores de riesgo adicionales o diferentes. En este estudio se revisan algunas características de los sangrados digestivos altos no varicosos asociados a la ingesta de AINES con la finalidad de coadyuvar al entendimiento de esta patología en pediatría.

The non-varicose upper digestive bleeding constitutes one of the principal forms of presentation for gastroenterophaty by non-steroidal anti-inflammatory drugs (NSAIDs). The relationship between NSAIDs and gastrointestinal lesions is well established; nevertheless most of the bibliographic information available derives from studies in adults. Similarly, the risk factors for this disease are limited to adults , but are assumed that the physiological and behavioral characteristics would suggest additional or different risk factors. In this study we review some characteristics of non varicose bleeding of the upper digestive tract associated with the ingestion of NSAIDs or the purpose of contributing to the understanding of this pathology in pediatrics.

Reações de hipersensibilidade a medicamentos: parte II / Drug hypersensivity reactions: part II

As reações de hipersensibilidade a medicamentos são comuns na prática clínica. A maioria das reações ocorrem por mecanismos não-imunológicos e não existem provas diagnósticas aplicáveis a todas as situações. O diagnóstico é particularmente complexo em pacientes em uso de vários medicamentos. Na Parte II do artigo sobre Hipersensibilidade a Medicamentos os autores analisam especificamente as reações a determinados qrupos de medicamentos: analgésicos e AINE, antibióticos, anticonvulsivantes, anestésicos locais, látex no ambiente cirúrgico, relaxantes neuromusculares, contrastes radiológicos e a situação especial de pacientes sensíveis a vários grupos de fármacos. O conhecimento das características das reações e da conduta mais apropriada determinam o sucesso no diagnóstico e orientação do paciente.

Adverse drug reactions are common conditions in clinical practice. The majority of these reactions occurs through non-immunologic mechanisms and there are no available validated diagnostic methods for all the situations. Diagnosis is specially difficult in patients who are using many medications. In Part II of Drugs Hypersensitivity authors analyse reactions to specifics drugs groups, as analgesics and NSAID, antibiotics, anticonvulsivants, local anesthetics, latex on surgical environment, neuromuscular relaxants, radiologic contrasts, and the special condition of patients with multiple drugs sensitivities. The knowledge of charatcteristics of the reactions and more appropriate management determine success in diagnosis and patient's guidance.
