RESUMEN

The study explored the hepatoprotective activity and metabolic profile of Verbena bonariensis L. methanol extract (VBM) and fractions using isoniazid as well as rifampicin-triggered liver toxicity in Wistar albino rats. Metabolite profiling of VBM using HPLC-PDA-ESI-MS identified 12 compounds, mainly iridoids, phenylpropanoids, and flavonoids, where verbascoside represents the major compound. Different biochemical parameters such as aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP), bilirubin, and total protein levels were used to assess liver functions. All the evaluated samples exhibited hepatoprotective potential, but VBM exhibited maximum activity and a notable decline in ALP (p < 0.05, significant), even better than the standard drug (silymarin). VBM significantly reduced the elevated ALT, AST, ALP, and total bilirubin. It also triggered a significant elevation in total proteins compared with diseased animals. This was further consolidated by histopathological studies. Verbena bonariensis L. could serve as a potent hepatoprotective agent and may alleviate liver ailments.

RESUMEN

Atriplex crassifolia (A. crassifolia) is a locally occurring member of Chenopodiaceae family that has been used in folk medicine for the treatment of joint pain and inflammation. The present study was focused to determine the analgesic and anti-inflammatory potential of the plant. n-hexane (ACNH) and methanol (ACM) extracts of A. crassifolia were evaluated for in vitro anti-inflammatory potential using protein denaturation inhibition assay. In vivo anti-inflammatory potential was determined by oral administration of 250, 500, and 1000 mg/kg/day of extracts against carrageenan and formalin-induced paw edema models. Inflammatory mediators such as TNF-α, IL-10, IL-1ß, NF-kB, IL-4, and IL-6 were estimated in blood samples of animals subjected to formalin model of inflammation. Analgesic activity was determined using acetic acid-induced writhing and tail flick assay model. Phytochemical profiling was done by GC-mass spectrophotometer. The results of in vitro anti-inflammatory activity revealed that both ACNH and ACM displayed eminent inhibition of protein denaturation in concentration-dependent manner. In acute in vivo carrageenan-induced paw edema model, both extracts reduced inflammation at 5th and 6th hour of study (p < 0.05). A. crassifolia extracts exhibited significant inhibition against formalin-induced inflammation with maximum effect at 1000 mg/kg. ACNH and ACM significantly augmented the inflammatory mediators (p < 0.05). Levels of TNF-α, IL-6, IL-1ß, and NF-kB were reduced, while those of IL-4 and IL-10 were upregulated. ACNH displayed maximum analgesic effect at 1000 mg/kg, while ACM showed potent activity at 500 and 1000 mg/kg. The extracts restored the CBC, TLC and CRP toward normal. GC-MS analysis revealed the presence of compounds like n-hexadecanoic acid, Phytol, (9E,11E)-octadecadienoic acid, 2-hydroxy-1-(hydroxymethyl) ethyl ester, 1-hexacosene, vitamin E, campesterol, stigmasterol, gamma sitosterol in both extracts. These compounds have been reported to suppress inflammation by inhibiting inflammatory cytokines. The current study concludes that A. crassifolia possesses significant anti-nociceptive and anti-inflammatory potential owing to the presence of phytochemicals.

RESUMEN

Background and Objectives: The increase in antimicrobial resistance (AMR) across countries has seriously impacted the effective management of infectious diseases, with subsequent impact on morbidity, mortality and costs. This includes Pakistan. Antimicrobial surveillance activities should be mandatory to continually assess the extent of multidrug-resistant bacteria and the implications for future empiric prescribing. The objective of this retrospective observational study was to monitor the susceptibility pattern of microbes in Pakistan. Materials and Methods: Clinical samples from seven laboratories in Punjab, Pakistan were collected between January 2018 and April 2019, with Punjab being the most populous province in Pakistan. The isolates were identified and their antimicrobial susceptibility was tested using the Kirby-Bauer disc diffusion assay and micro broth dilution methods. The antibiotics assessed were those typically prescribed in Pakistan. Results: In total, 2523 bacterial cultural reports were studied. The most frequently isolated pathogens were Staphylococcus aureus (866, 34.3%), followed by Escherichia coli (814, 32.2%), Pseudomonas aeruginosa (454, 18.0%) and Klebsiella pneumoniae (269, 10.7%). Most pathogens were isolated from pus (1464, 58.0%), followed by urine (718, 28.5%), blood (164, 6.5%) and sputum (81, 3.2%). Conclusions: The findings suggest that current antimicrobial options are severally restricted in Pakistan due to the emergence of multidrug-resistant pathogens. This calls for urgent actions including initiating antimicrobial stewardship programs to enhance prudent prescribing of antibiotics. This includes agreeing on appropriate empiric therapy as part of agreed guidelines, in line with the WHO EML and AWaRe book, whilst awaiting culture reports. This is alongside other measures to reduce inappropriate antimicrobial prescribing and reverse the threat of rising AMR.

RESUMEN

Marchantia species were traditionally used to treat liver failure. Marchantia polymorpha chloroform extract showed a marked hepatoprotective activity in a dose-dependent manner in paracetamol-induced extensive liver damage in mice. At a dose of 500 mg/kg (MP-500), it resulted in a reduction in aspartate transaminase by 49.44%, alanine transaminase by 44.11%, and alkaline phosphatase by 24.4% with significant elevation in total proteins by 58.69% with respect to the diseased group. It showed significant reductions in total bilirubin, total cholesterol, triglycerides, low density lipoprotein (LDL), very LDL, total lipids, and to high density lipoprotein ratio (CH/HDL) by 53.42, 30.14, 35.02, 45.79, 34.74, 41.45, and 49.52%, respectively, together with a 37.69% increase in HDL with respect to the diseased group. It also showed an elevation of superoxide dismutase by 28.09% and in glutathione peroxidase by 81.83% in addition to the reduction of lipid peroxidation by 17.95% as compared to the paracetamol only treated group. This was further supported by histopathological examination that showed normal liver architecture and a normal sinusoidal gap. Metabolic profiling by ultrahigh performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer (UHPLC-QTOF/MS) led to the tentative identification of 28 compounds belonging to phenols, quinolones, phenylpropanoid, acylaminosugars, terpenoids, lipids, and fatty acids to which the activity was attributed. Four compounds were detected in the negative ionization mode which are neoacrimarine J, marchantin A, chitobiose, and phellodensin F, while the rest were detected in the positive mode. Thus, it can be concluded that this plant could serve as a valuable choice for the treatment of hepatotoxicity that further consolidated its traditional use.

RESUMEN

Antimicrobial resistance (AMR) is an increasing global concern, increasing costs, morbidity, and mortality. National action plans (NAPs) to minimize AMR are one of several global and national initiatives to slow down rising AMR rates. NAPs are also helping key stakeholders understand current antimicrobial utilization patterns and resistance rates. The Middle East is no exception, with high AMR rates. Antibiotic point prevalence surveys (PPS) provide a better understanding of existing antimicrobial consumption trends in hospitals and assist with the subsequent implementation of antimicrobial stewardship programs (ASPs). These are important NAP activities. We examined current hospital consumption trends across the Middle East along with documented ASPs. A narrative assessment of 24 PPS studies in the region found that, on average, more than 50% of in-patients received antibiotics, with Jordan having the highest rate of 98.1%. Published studies ranged in size from a single to 18 hospitals. The most prescribed antibiotics were ceftriaxone, metronidazole, and penicillin. In addition, significant postoperative antibiotic prescribing lasting up to five days or longer was common to avoid surgical site infections. These findings have resulted in a variety of suggested short-, medium-, and long-term actions among key stakeholders, including governments and healthcare workers, to improve and sustain future antibiotic prescribing in order to decrease AMR throughout the Middle East.

RESUMEN

Cassia absus, a member of Fabaceae family, has been a part of traditional medicine for various ailments such as Hypertension, Diabetes, and Cancer. This family of plants has been utilized for Anticonvulsant and Anxiolytic effects. The ongoing investigation is aimed to seek the antiepileptic potential of C. absus seed extracts in pentylenetetrazole-induced kindling mice. The seeds of C. absus were subjected to a sequential extraction process for the preparation of n-hexane, chloroform, methanol, and aqueous extracts. The PTZ-induced kindling model was employed to assess the antiepileptic activity of each extract. Seizure activity and antioxidant biomarkers in the brain tissue such as levels of CAT, SOD, tGSH, and MDA were assessed. Mechanism of action was elucidated by Flumazenil. Through GC-MS analysis, the phytochemical components in the chloroform extract of C. absus were evaluated. The outcomes showed that C. absus extracts markedly reduced the seizure activity in kindling mice. The extracts exhibited significant Antioxidant properties by enhancing the levels of antioxidant biomarkers in the brain tissue such as CAT, SOD, and tGSH, and decreasing the MDA level. The results demonstrated that C. absus extracts showed antiepileptic effects may be via GABA pathway. According to the results of this investigation, C. absus has significant antiepileptic potential in PTZ-induced kindling mice via GABA pathway modulation and combating reactive oxygen species.

RESUMEN

People of Pakistan have undisturbed customs for the employment of medicinal plants for healthcare requisites. Chloroform extract of F. hygrometrica (CE FH) was examined for its ability to reduce inflammation and to produce analgesia. Carrageenan and formalin-induced paw edema model for inflammatory activity, hot-plate and tail-flick methods to assess analgesic activity were executed. Phytochemical analysis was done by UHPLC-MS and GC-mass spectrometer. The results demonstrated that in carrageenan-induced paw edema, maximum reduction in inflammation was observed at 5th hour at the dose 100 mg/kg; while at doses 250 and 500 mg/kg, maximum response was observed at 5th and 6th hours. Analgesic activity results indicated that maximum analgesia was observed up to 120 min at 100 mg/kg, while up to 90 min in case of 250 and 500 mg/kg doses. The formalin-induced rat paw edema showed significant (p < 0.05) anti-inflammatory activity after 5 days treatment. After, testing period of 10 days, the biochemical parameters such as CBC, CRP, serum enzymes like CAT, SOD, GSH and inflammatory mediators like TNF-α, IL-6, IL-4 and IL-10 were estimated. The administration of formalin resulted in an increase in the level of leucocytes, total WBC, CRP, serum enzymes and in the diameters of paw thickness, while pre-treatment with CE FH at dose levels of 100, 250 and 500 mg/kg exhibited a diminution in the levels of SOD, GSH, CAT, total RBC and HB. Acute inflammatory mediators such as TNFα, IL -6 and IL-4 were reduced, and IL-10 was upregulated in the treated group as compared to the control. Many phytoconstituents, i.e., chitobiose, chlorovulone III, γ-tocotrienol, emmotin, cassine, hexacosanedioic acid, neophytadiene, fumaric acid, neophytadiene, hexadecanoic acid, phytol and stigmasterol were detected during UHPLC-MS and GC-MS analysis seems to be responsible for the said activity in correlation with the already reported data about these compounds. The results concluded that CE FH possess noteworthy anti-inflammatory and central analgesic action at different doses (100, 250 and 500 mg/kg).

RESUMEN

Prevalence of oral infections in diabetic patients is a health challenge due to persistent hyperglycemia. However, despite great concerns, limited treatment options are available. We therefore aimed to develop nanoemulsion gel (NEG) for oral bacterial infections based on essential oils. Clove and cinnamon essential oils based nanoemulgel were prepared and characterized. Various physicochemical parameters of optimized formulation including viscosity (65311 mPa·S), spreadability (36 g·cm/s), and mucoadhesive strength 42.87 N/cm2) were within prescribed limits. The drug contents of the NEG were 94.38 ± 1.12% (cinnamaldehyde) and 92.96 ± 2.08% (clove oil). A significant concentration of clove (73.9%) and cinnamon essential oil (71.2 %) was released from a polymer matrix of the NEG till 24 h. The ex vivo goat buccal mucosa permeation profile revealed a significant (52.7-54.2%) permeation of major constituents which occurred after 24 h. When subjected to antimicrobial testing, significant inhibition was observed for several clinical strains, namely Staphylococcus aureus (19 mm), Staphylococcus epidermidis (19 mm), and Pseudomonas aeruginosa (4 mm), as well as against Bacillus chungangensis (2 mm), whereas no inhibition was detected for Bacillus paramycoides and Paenibacillus dendritiformis when NEG was utilized. Likewise promising antifungal (Candida albicans) and antiquorum sensing activities were observed. It was therefore concluded that cinnamon and clove oil-based NEG formulation presented significant antibacterial-, antifungal, and antiquorum sensing activities.

RESUMEN

Background: Antibiotic de-escalation is a key element of antimicrobial stewardship programs that restrict the spread and emergence of resistance. This study was performed to evaluate the impact of positive culture sensitivity reports of E. coli or Methicillin sensitive Staphylococcus aureus (MSSA) on de-escalation of antibiotic therapy. Methods: This prospective observational study was performed on 256 infected patients. The samples were obtained principally from the pus of infected sites for the identification of pathogens and culture-sensitivity testing. The data were collected from patient medical files, which included their demographic data, sample type, causative microbe and antimicrobial treatment as empiric or definitive treatment based on cultures. Data were analyzed using SPSS. Results: Of 256 isolated microbes, 138 (53.9%) were MSSA and 118 were E. coli (46.1%). MSSA showed 100% sensitivity to cefoxitin, oxacillin, vancomycin, fosfomycin, colistin and more than 90% to linezolid (95.3%), tigecycline (93.1%), chloramphenicol (92.2%) and amikacin (90.2%). E. coli showed 100% sensitivity to only fosfomycin and more than 90% to colistin (96.7%), polymyxin-B (95.1%) and tigecycline (92.9%). The high use of cefoperazone+sulbactam (151), amikacin (149), ceftriaxone (33), metronidazole (30) and piperacillin + tazobactam (22) was seen with empiric prescribing. Following susceptibility testing, the most common antibiotics prescribed for E. coli were meropenem IV (34), amikacin (34), ciprofloxacin (29) and cefoperazone+sulbactam (25). For MSSA cases, linezolid (48), clindamycin (30), cefoperazone+ sulbactam IV (16) and amikacin (15) was used commonly. Overall, there was 23% reduction in antibiotic use in case of E. coli and 43% reduction in MSSA cases. Conclusion: Culture sensitivity reports helped in the de-escalation of antimicrobial therapy, reducing the prescribing of especially broad-spectrum antibiotics. Consequently, it is recommended that local hospital guidelines be developed based on local antimicrobial susceptibility patterns while preventing the unnecessary use of broad-spectrum antibiotics for empiric treatment.

RESUMEN

Saussurea hypoleuca belongs to the family Asteraceae, which has previously shown hepatoprotective, anticancer, and antioxidant activity. This study aimed to evaluate the antihyperglycemic and antihyperlipidemic activity of its root methanol extract and various fractions for the first time. This was performed using alloxan-induced diabetes in the rat model for both short, and long-term periods using different administration doses. Different biochemical parameters were studied and further consolidated by histopathological examination and in silico molecular modeling. The results showed that in the long-term study, at a dose of 400 mg/kg b.wt, the ethyl acetate fraction caused a pronounced reduction in fasting blood glucose level (FBG) and glycated hemoglobin (HbA1c) by 77.2% and 36.8%, respectively, compared to the diabetic group. This was confirmed by the histopathological examination of the animals' pancreatic sections. The ethyl acetate fraction also showed a reduction in total cholesterol (TC), total glycerides (TG), and low-density lipoprotein cholesterol (LDL-C) levels. It improved kidney and liver functions, causing a reduction in aspartate aminotransferase (AST), alkaline phosphatase (ALP), alanine transaminase (ALT), urea, and creatinine levels. This is mainly attributed to its richness in secondary metabolites. Molecular docking showed that all the tested compounds showed certain inhibitory potential towards human α-glucosidase (HAG) and ATP citrate lyase (ACL). Thus, Saussurea hypoleuca roots can help in the management of hyperglycemia, hyperlipidemia, and hepatic and kidney dysfunction.

RESUMEN

Pakistan has reported a substantial number of COVID-19 cases since 2020. A multicenter observational study was conducted to identify the pattern of SARS-CoV-2 infection, transmission, and treatment in patients admitted to seven low to middle-income district hospitals in the Province of Punjab, Pakistan from March to June 2020. A total of 102 patients were recruited. 57 patients tested positive and 45 developed moderate-severe COVID-19 disease. About 67% of the patients in March-April and 93% in May-June have contracted the disease from the local transmission. The mean number of symptoms in SARS-CoV-2 positive patients was significantly higher than suspected patients (6.46 vs 5.04, p=0.003). The number of deaths was low (n=8) with 86% recovery rate. Mild COVID patients received acetaminophen (n=102), azithromycin (n=8), and hydroxychloroquine (n=4) in addition to standard medical care. The treatment provided to moderate-severe cases included acetaminophen (45/45), azithromycin (45/45), Ivermectin (14/45) and corticosteroids (13/45). The mean number of antimicrobials was significantly higher in moderate-severe patients than mild cases (1.80 vs 1.12, p=0.001). Low number of deaths with a high recovery rate was reported. Diabetes was the most common comorbid condition followed by hypertension. Many antimicrobials were prescribed in both mild and moderate-severe cases that require careful review.

RESUMEN

Pulmonary toxicity by anticancer drugs often leads to discontinuation of therapy or switching the therapy to alternative drugs. In the present study, serratiopeptidase (SPTD) and fisetin (FST) were evaluated as chemoprotectant to counteract the pulmonary toxicity induced by BLM and MTX. Single dose of MTX (20 mg/kg) by intraperitoneal and BLM (5 mg/kg) by intra-tracheal route was administered on 7th day of study. SPTD (20 mg/kg), FST (25 mg/kg), and NAC (250 mg/kg) and combinations of SPTD + NAC, SPTD + FST, and FST + NAC were administered through oral gavage for 14 days. SPTD and FST showed significant (p < 0.05) effect in MTX-induced lung toxicity by increasing reduced glutathione (GSH) and decreasing malondialdehyde (MDA), hydroxyproline (HXP), and collagen. SPTD and NAC showed significant (p < 0.05) effect in BLM-induced pulmonary toxicity by increasing GSH and decreasing MDA, HXP, and collagen whereas FST was not much effective. In combination study, SPTD + NAC combination showed significant (p < 0.05) effect in BLM- and MTX- induced lung injury whereas other combinations did not prove to be highly effective. SPTD can be recommended along with BLM and MTX in chemotherapy protocol alone and in combination with NAC.

RESUMEN

Numerous studies on risk factors, clinical presentation and treatment of hepatitis C are known to the world. However, no data is available about the safety and efficacy of anti-hepatitis C therapy among the patients of Gujranwala, Pakistan. This retrospective study compared two dosage forms of interferon; conventional interferon (IR) and Pegylated interferon (PIR) in 370 Hepatitis C patients selected through non probability convenient sampling technique. Clinical data were collected related to therapy outcomes at the start of therapy, after each follow up and at the end of therapy. The study indicated that HCV 3 was the most prevalent genotype of hepatitis C. Main side effects associated with therapies were pain at injection site (PIR; 49%, IR; 48%), inflammation at injection site (PIR; 34%, IR; 48%), fever (PIR; 56.12%, IR; 61.5%), myalgia (PIR; 24.5%,IR; 22.99%), malaise (PIR; 7.14%, IR; 5.75%), anorexia (PIR; 46%, IR; 39%), vomiting (PIR; 43%, IR; 41%), irritability (PIR; 4%, IR; 11.5%) and impaired concentration (PIR; 13%, IR; 21). The sustained viral response rate was significantly better in PIR group as compared to IR group (PIR; 80.61%, IR; 66.67%). In conclusion Pegylated interferon based therapy showed better clinical response with less adverse events as compared to conventional interferon based therapy. However, there is dire need to shift from these intravenous dosage forms to relatively new oral dosage forms for the treatment of hepatitis C to further improve clinical outcome and minimize the risks of adverse events.

RESUMEN

BACKGROUND: Herbology is the prevailing system among the nationally-accepted alternative or complementary systems of medicine. The system is due to its general and patient-oriented methodology, is widely used in the general population exposing them to the risk of the side effects of the herbal medicines. METHOD: The aim of study was to assess the acute and sub-acute toxicity of the polyherbal formulation Hab-e-Kabad Noshadri tablets. In the acute arm of the study, a single dose of 2000 mg/kg was administered to Swiss Albino mice which were observed for physical symptoms and behavioral changes for 72 h. In sub-acute toxicity study repeated doses of the polyherbal preparation was administered to Wistar rats of both genders, separately. The animals received three doses of polyherbal product (50 mg/kg/day, 100 mg/kg/day and 200 mg/kg/day) for a period of 28 days. On 28th day of experiment, blood sampling of animals was done for hematological and biochemical analysis i.e. liver and renal function parameters, lipid profile and then sacrificed for histopathological examination of liver and kidney. RESULT: There was no morbidity and mortality noticed with single dose administration in acute toxicity study in mice. In sub-acute toxicity study, morphological changes with some damage in liver and kidney tissues of male and female animals were recorded at dose of 100 mg/kg/day and 200 mg/kg/day. CONCLUSIONS: It was found that prolonged use at higher dose i.e. 200 mg/kg/day of this polyherbal formulation should be avoided and practitioners should cautiously prescribe this formulation in patients with hepatic and renal impairment.

RESUMEN

OBJECTIVE: To evaluate the phytochemical and in vitro antioxidant ability of methanolic extract and different fractions of Amaranthus graecizans subsp. silvestris (A. graecizans subsp. silvestris). METHODS: Methanolic extract of A. graecizans subsp. silvestris was obtained by cold maceration and then methanolic extract was subjected to fractionation and different fractions i.e. n-hexane, chloroform, ethyl acetate, n-butanol and aqueous fractions were obtained. Methanolic extract and all other fractions were subjected to phytochemical investigation by performing different phytochemical group tests like alkaloid, tannins, carbohydrates, lipids, proteins, etc. In vitro antioxidant activity of A. graecizans subsp. silvestris was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl radical (DPPH), ferric thiocyanate assay, total antioxidant activity by phosphomolybdenum, ferric reducing antioxidant power, total phenolic content and lipid peroxidation methods. RESULTS: Maximum antioxidant activity was shown by n-hexane fraction of the extract by carrying out DPPH (86.44±0.23), ethyl acetate fraction by total antioxidant (0.95±0.06) and ferric reducing antioxidant power (299.45±1.48) methods, while by employing total phenolic contents and inhibition of lipid per oxidation assays, methanolic extract (92.88±4.16) and n-hexane fraction (69.47±0.68) exhibited maximal activity. Ethyl acetate fraction showed the least IC50 values by DPPH assay, hence a more pronounced potential for antioxidant activity. CONCLUSIONS: The results indicate that A. graecizans subsp. silvestris has antioxidant potential and can be utilized as a natural source of antioxidant.

RESUMEN

Curcuma longa (C. longa) is commonly found in different areas of Pakistan. It has been locally utilized as a traditional medicine. The aim of this study was to evaluate the antidiabetic, hepatoprotective and total antioxidant effect of the crude drug and its methanolic extract in rabbits. Diabetes was induced with alloxan (180mg/kg). Two major groups were designed, curative and protective groups. In curative group the crude drug and its methanolic extract was orally administered to the diabetic animals and acute study was performed. On the other hand in protective group the crude drug and its methanolic extract were administered for eight days prior to the diabetes induction. Results indicated that in Curative group the crude and methanolic extract of C. longa significantly improved the levels of serum glucose, serum transaminases and antioxidant activity (AOA). In protective group, serum glucose, serum transaminases were not significantly increased by alloxan, in both crude as well as methanolic extract group.
