RESUMO
AZD1222 (ChAdOx1 nCoV-19) is a replication-deficient adenoviral vectored coronavirus disease-19 (COVID-19) vaccine that is manufactured as SII-ChAdOx1 nCoV-19 by the Serum Institute of India Pvt Ltd following technology transfer from Oxford University/AstraZeneca. The non-inferiority of SII-ChAdOx1 nCoV-19 with AZD1222 was previously demonstrated in an observer-blind, phase 2/3 immuno-bridging study (trial registration: CTRI/2020/08/027170). In this analysis of immunogenicity and safety data 6 months post first vaccination (Day 180), 1,601 participants were randomized 3:1 to SII-ChAdOx1 nCoV-19 or AZD1222 (immunogenicity/reactogenicity cohort n = 401) and 3:1 to SII-ChAdOx1 nCoV-19 or placebo (safety cohort n = 1,200). Immunogenicity was measured by anti-severe acute respiratory syndrome coronavirus 2 spike (anti-S) binding immunoglobulin G and neutralizing antibody (nAb) titers. A decline in anti-S titers was observed in both vaccine groups, albeit with a greater decline in SII-ChAdOx1 nCoV-19 vaccinees (geometric mean titer [GMT] ratio [95% confidence interval (CI) of SII-ChAdOx1 nCoV-19 to AZD1222]: 0.60 [0.41-0.87]). Consistent similar decreases in nAb titers were observed between vaccine groups (GMT ratio [95% CI]: 0.88 [0.44-1.73]). No cases of severe COVID-19 were reported following vaccination, while one case was observed in the placebo group. No causally related serious adverse events were reported through 180 days. No thromboembolic or autoimmune adverse events of special interest were reported. Collectively, these data illustrate that SII-ChAdOx1 nCoV-19 maintained a high level of immunogenicity 6 months post-vaccination. SII-ChAdOx1 nCoV-19 was safe and well tolerated.

BACKGROUND: Toxic Epidermal Necrolysis (TEN) is a rare, acute, and life-threatening mucocutaneous disease that occurs after the administration of certain drugs, resulting in extensive keratinocyte cell death, skin involvement at the dermal-epidermal junction, and extensive bullous skin eruptions and sloughing. Many published case reports have observed the presence of fever with a viral infection, drug, and/or genetic association as a possible trigger for TEN but associated with other comorbidities. Physicians still struggle to predict which individuals could be predisposed to TEN. The case report that we present had a history of multiple drug intake and fever due to dengue virus infection but was not associated with any other comorbidity. CASE PRESENTATION: We present an unusual case of a 32-year-old woman of Western Indian origin who had developed dengue infection and suffered toxic epidermal necrolysis following a five-day course of a third-generation cephalosporin antibiotic, cefixime and a three-day course of 2 analgesic drugs, paracetamol (acetaminophen), and nimesulide, with the adverse event occurring on the fifth day of the dengue infection. The offending drugs were stopped, and patient survived with supportive management and hydration. CONCLUSION: The presence of comorbidities may not always be the triggering factor for TEN, though it can affect patient outcomes. Rational drug use is always recommended for patient care. Further research is required to understand the pathomechanism behind the viral-drug-gene interaction.

Introduction: In 2019, the Central Drugs Standard Control Organization (CDSCO) introduced the New Drugs and Clinical Trials Rules 2019 (NDCTR), which separated the research guidelines for "Clinical Trials" and "Biomedical and Health Research." As a result, guidelines issued by Indian Council of Medical Research were stated to apply to academic clinical trials (ACTs). This change is important because academic studies are crucial for scientific advancement and repurposing of approved drugs in health-care industry. However, conducting an ACT can pose challenges. We assessed the level of awareness, knowledge, and challenges faced by investigators. Our aim is to overcome some of these challenges and encourage more academic studies for the betterment of healthcare and scientific knowledge in India. Methodology: The study was conducted in two phases after obtaining approval from the Institutional Ethics Committee (EC) of three tertiary care hospitals in Mumbai. In the first phase, the number of ACTs was assessed from the clinical trial registry India website, while the number of registered and re-registered ECs were assessed from the CDSCO website. The second phase involved assessing investigator awareness and knowledge about ACTs using a prevalidated questionnaire with a content validity index score of 0.93. Results: In 2020, the highest numbers of studies were registered, with the highest numbers of registered and re-registered ECs from Maharashtra. All participants completed the questionnaire and were aware of the need to follow guidelines for clinical trials. Sixty-seven percent of participants knew that the guidelines for ACTs differed from those of sponsored clinical trials, but only 58% were aware of the exact definition of an ACT as per NDCTR, 2019. Eighty-five percent of participants knew who could initiate an ACT, but only 27% knew about the applicability of results of an ACT and 33% had in-depth knowledge about the required approvals, while only 10% knew the archival period. Although 71% of participants had knowledge about serious adverse event reporting, few answered in-depth questions correctly. Only 31 participants reported facing varied challenges. Conclusion: To conduct ACTs effectively and contribute to healthcare and scientific advancement, it is crucial to enhance investigators' existing knowledge about ACTs.
RESUMO
BACKGROUND: Prediabetes is an intermediate state of hyperglycemia, which acts as a precursor to Diabetes mellitus if left untreated. Nisha (Curcuma longa) and Amalaki (Emblica officinalis) combination has been advocated as drugs of choice to treat the early manifestations of Diabetes mellitus. OBJECTIVE: This prospective, randomized, single-blind, placebo-controlled, comparative study was planned to assess the efficacy and safety of Nisha-Amalaki capsules in preventing progression to Diabetes mellitus in prediabetic patients when administered for 6 months. METHODS: The study was conducted on prediabetic participants randomized to receive either Nisha-Amalaki (500 mg) or placebo one capsule twice a day for six months. The effect of study medications on IDRS (Indian Diabetes Risk Score), BMI (Body Mass Index), blood sugar, serum insulin, HOMA-IR (Homeostasis Model Assessment-Estimated Insulin Resistance), HbA1c (glycated hemoglobin), oxidative markers, Ayurvedic symptoms and Quality of Life (QoL) scores was assessed at regular intervals. RESULTS: 58 of the 62 participants enrolled completed the study. Significant fall in IDRS score [p < 0.001], BMI [p < 0.001], fasting, and 2 h post-OGTT sugar, insulin, HbA1c, HOMA-IR, and oxidative stress markers [p < 0.001] was observed in patients receiving Nisha-Amalaki at 6 months. Ayurvedic symptoms and QoL scores also improved at 6 months in the treatment group. CONCLUSION: Treatment with Nisha-Amalaki capsules improved all study parameters including insulin sensitivity at 6 months as compared to placebo in prediabetic patients. Thus Nisha-Amalaki should be considered as prophylactic therapy in prediabetics to delay progression to diabetes.
RESUMO
Importance: The recombinant COVID-19 vaccine NVX-CoV2373 has demonstrated efficacy of approximately 90% in adults; however, its safety and efficacy in children is unknown. Objective: To assess the noninferiority of SII-NVX-CoV2373 in children and adolescents compared to adults and to evaluate its safety in comparison with placebo. Design, Setting, and Participants: This phase 2-3 observer-blind randomized clinical trial was conducted in 2 cohorts, children (aged 2 to 11 years) and adolescents (aged 12 to 17 years) between August 2021 and August 2022. Participants were randomized 3:1 to SII-NVX-CoV2373 or placebo and monitored for 179 days. The participants, study team, and laboratory staff were blinded. This was a multicenter study conducted across 10 tertiary care hospitals in India. Exclusion criteria included previous COVID-19 infection or vaccination, immunocompromised condition, and immunosuppressive medications. Interventions: Two doses of 0.5-mL SII-NVX-CoV2373 or placebo were administered intramuscularly on days 1 and 22. Main Outcomes and Measures: Primary outcomes were geometric mean titer ratio of both anti-spike (anti-S) IgG and neutralizing antibodies (NAbs) between both pediatric age groups to that of adults on day 36. Noninferiority was concluded if the lower bound of 95% CI of this ratio was greater than 0.67 for each age group. Both the antibodies were assessed for the index strain and for selected variants at various time points. Solicited adverse events (AEs) were recorded for 7 days after each vaccination, unsolicited AEs were recorded for 35 days, and serious AEs and AEs of special interest were recorded for 179 days. Results: A total of 460 children in each age cohort were randomized to receive vaccine or placebo. The mean (SD) age was 6.7 (2.7) years in the child cohort and 14.3 (1.6) years in the adolescent cohort; 231 participants (50.2%) in the child cohort and 218 in the adolescent cohort (47.4%) were female. Both anti-S IgG and NAb titers were markedly higher in the SII-NVX-CoV2373 group than in the placebo group on both day 36 and day 180. The geometric mean titer ratios compared to those in adults were 1.20 (95% CI, 1.08-1.34) and 1.52 (95% CI, 1.38-1.67) for anti-S IgG in adolescents and children, respectively; while for NAbs, they were 1.33 (95% CI, 1.17-1.50) and 1.93 (95% CI, 1.70-2.18) in adolescents and children, respectively, indicating noninferiority. SII-NVX-CoV2373 also showed immune responses against variants studied. Injection site reactions, fever, headache, malaise, and fatigue were common solicited AEs. There were no AEs of special interest and no causally related serious AEs. Conclusions and Relevance: SII-NVX-CoV2373 was safe and well tolerated in children and adolescents in this study. The vaccine was highly immunogenic and may be used in pediatric vaccination against COVID-19. Trial Registration: Clinical Trials Registry of India Identifier: CTRI/2021/02/031554.
RESUMO
Introduction: Since June 15, 2009, clinical trial registration in the Clinical Trial Registry-India (CTRI) has been made mandatory by the Drugs Controller General of India to improve transparency, accountability, conform to accepted ethical standards and reporting of all relevant results of registered trials. In this study, we planned to evaluate the compliance of Indian and global sponsors with clinical trials conducted in India in terms of reporting of clinical trial results at the CTRI. Methods: We included trials registered in the CTRI between January 2018 and January 2020. The CTRI and ClinicalTrials.gov registry was thoroughly searched for all completed interventional studies. A year-wise comparative analysis was performed to evaluate the number of clinical trials reporting results in both the registry. Results: The reporting of completed interventional clinical trial results was 25/112 (22.32%) in year 2018, y, 8/105 (7.6%) in year 2019 and 17/140 (12.14%) in year 2020. There was significantly less reporting of results of Pharmaceutical company sponsored Interventional Studies-Indian at CTRI when compared with ClinicalTrials.gov registry for the year 2019 (odds ratio [OR]-0.17 (95% confidence interval [CI]: 0.08-0.36) and P < 0.0001) and year 2020 (OR-0.45 [95% CI: 0.24-0.82] and P < 0.01). The difference in results reported at CTRI was significantly low for Pharmaceutical company sponsored Interventional Studies-Global only for year 2019 (OR-0.09 [95% CI: 0.005-1.45] and P = 0.04) compared with ClinicalTrials.gov. Conclusion: There is a need to develop the culture of reporting clinical trial results in CTRI to strengthen the transparency in the research for overall benefit of public, health care professionals, and research community.
RESUMO
BACKGROUND: This study assessed safety and immunogenicity of Serum Institute of India Pvt Ltd (SIIPL)'s tetanus toxoid (TT), diphtheria toxoid (DT), and acellular pertussis booster vaccine (Tdap). RESEARCH DESIGN AND METHODS: In this Phase II/III, multicenter, randomized, active-controlled, open-label study, 1500 healthy individuals, aged 4-65 years, were randomized to receive a single dose of SIIPL Tdap or comparator Tdap vaccine (Boostrix®; GlaxoSmithKlines, India). Adverse events (AEs) during initial 30 minutes, 7-day, 30-day post-vaccination were assessed. Blood samples were taken before and 30 days post-vaccination for immunogenicity assessment. RESULTS: No significant differences in incidence of local and systemic solicited AEs were observed between the two groups; no vaccine-related serious AEs were reported. SIIPL Tdap was non-inferior to comparator Tdap in achieving booster responses to TT and DT in 75.2% and 70.8% of the participants, respectively, and to pertussis toxoid (PT), pertactin (PRN), and filamentous hemagglutinin (FHA) in 94.3%, 92.6%, and 95.0% of the participants, respectively. Anti-PT, anti-PRN, and anti-FHA antibody geometric mean titers in both the groups, were significantly higher post-vaccination compared to pre-vaccination. CONCLUSIONS: Booster vaccination with SIIPL Tdap was non-inferior to comparator Tdap with respect to immunogenicity against tetanus, diphtheria, and pertussis and was well tolerated.

In this study we present pH-responsive rifampicin (RIF) microparticles comprising lecithin and a biodegradable hydrophobic polymer, polyethylene sebacate (PES), to achieve high intramacrophage delivery and enhanced antitubercular efficacy. PES and PES-lecithin combination microparticles (PL MPs) prepared by single step precipitation revealed average size of 1.5 to 2.7 µm, entrapment efficiency â¼ 60 %, drug loading 12-15 % and negative zeta potential. Increase in lecithin concentration enhanced hydrophilicity. PES MPs demonstrated faster release in simulated lung fluid pH 7.4, while lecithin MPs facilitated faster and concentration dependent release in acidic artificial lysosomal fluid (ALF) pH 4.5 due to swelling and destabilization confirmed by TEM. PES and PL (1:2) MPs exhibited comparable macrophage uptake which was â¼ 5-fold superior than free RIF, in the RAW 264.7 macrophage cells. Confocal microscopy depicted intensified accumulation of the MPs in the lysosomal compartment, with augmented release of coumarin dye from the PL MPs, confirming pH-triggered increased intracellular release. Although, PES MPs and PL (1:2) MPs displayed comparable and high macrophage uptake, antitubercular efficacy against macrophage internalised M. tuberculosis was significantly higher with PL (1:2) MPs. This suggested great promise of the pH-sensitive PL (1:2) MPs for enhanced antitubercular efficacy.

Melanocortins are tiny protein molecules formed by the post-translational cleavage of proopiomelanocortin. These are bioactive peptides that are responsible for human and lower animal pigmentation patterns, energy homeostasis, and sexual function modulation. These peptides regulate numerous physiological functions by being generated in the central nervous system and peripheral tissues. Melanocortins elicit their varied biological effects by binding to a separate family of G protein, two primary proteolytic enzymes, proconvertases 1 and 2, according to recent research. These breakthroughs have opened up new avenues for research into the role of melanocortins, antagonists, and receptors in a number of physiological activities.

BACKGROUND: Nursing students and employees remain the first point of contact in case a patient develops an adverse drug reaction in hospital settings. Thus, it is important for nurses to understand the importance of pharmacovigilance activity and implement the same in their practice. They can also contribute to drug safety by reducing medication errors and adverse drug reaction reporting. METHODS: After ethics approval, an observational questionnaire-based study was conducted in 2017 that involved nursing students and nursing employees (N=390) to assess their baseline knowledge, attitude, and practice toward pharmacovigilance. Participants who consented were enrolled and a pre-training survey was conducted. Pharmacovigilance sensitization/ training sessions were conducted in the same year after getting their baseline data. Three years later in 2021, the same questionnaire was distributed to a subset of nursing students and employees (N=299) to analyze any change in their knowledge, attitude, and practice towards the pharmacovigilance activity as a posttest. Pre and post sensitization session questionnaire-based survey data was analyzed to confirm the long-term impact of conducting such pharmacovigilance awareness training. RESULTS: The nurses' overall performance before and after training in each of the domains of knowledge, attitude and practice were 17.53%, 72.86%, 39.69% in the pretest group, respectively, and post test scores were 30.77%, OR-3.04, p=0.0 (Knowledge), 85.92%, OR-0.14, p=0.0 (Attitude) and 37.21%, OR-0.08, p=0.08 (Practice) in the corresponding domain. Overall, there was a declining trend in the practice domain of the nurses response between the pre-test and post intervention groups however this decline was not statistically significant (p=0.08). CONCLUSION: Pharmacovigilance awareness training and sensitization programs had an impact on the knowledge and attitude of nurses but there is a need to ensure that it is implemented in clinical practice.

BACKGROUND AND RATIONALE: The coronavirus disease 2019 (COVID-19) pandemic has left no person unexposed to the wisdom about the need for human preparedness to tackle future pandemics irrespective of individual caste, race, religion, and education status. The extent of this change in knowledge and public perspective is difficult to measure in a populous nation like India subjected to individual freedom and cultural beliefs. Hence, we planned this study with the objective of evaluating the knowledge and perception of the Indian public towards COVID-19 disease, vaccination and research activities associated with the COVID-19 pandemic. MATERIALS AND METHODS: This is an observational, single-center, cross-sectional study (n = 244) conducted after obtaining approval from the Ethics Committee for Academic Research Projects. All consenting study participants, Indian residents aged > 18 years, were administered a prevalidated and structured questionnaire and interviewed for their honest opinion. The outcome measures were to evaluate the knowledge and perception of the study participants in each of the domains of COVID-19 disease, COVID-19 vaccination, and COVID-19-related clinical research. Demographic characteristics were summarized using descriptive statistics. All analyses were done at a 5% significance level using GraphPad InStat version 3.1. Data on the proportion of participants' responses to the questions in each of the three domains of COVID-19 disease (D), COVID-19 vaccination (V), and COVID-19-related research (R) were assessed. RESULTS: Study participants who knew the causative agent for coronavirus disease were 93.03% (227/244), nomenclature (77.45%, 189/244), those who could define pandemic (89.34%, 218/244), preventive measures against covid (96.31%, 235/244), lungs as the most common organ affected (96.31%, 235/244) and all answered that the origin of novel coronavirus was China. The majority of them felt that COVID-19 pandemic waves would never end (39.34%, 96/244), there was no effective drug/vaccine therapy available, and the lack of oxygen/hospital beds (39%) resulted in maximum mortality, and 47.13% (115/244) were worried about future bioterrorism. The lockdown measures were justified by 161/244 (65.98%), and 93.85% supported lockdown measures to curb the spread of infection. The improvement in air quality/environment hygiene, realizing the importance of hygiene, vaccine and disease, and spending quality time with family were the best three things to happen during the pandemic, while the loss of wages, nonavailability of medicines/vaccines/oxygen/hospital beds with mental/physical health deterioration were the worst three things experienced by people. Regarding COVID-19 vaccination, the most common reason to get vaccinated was to prevent infection/critical outcomes of COVID-19 (78.27%, 191/244); 79% already suffered COVID-19 prior to vaccination, while 68.85% suffered a COVID-19 infection after taking the vaccine which was mostly asymptomatic/mild. Almost 56.96% (139/244) participants supported compulsory vaccination for all in the larger interest of society and to prevent fatal COVID-19 outcomes. There were safety concerns mainly with accelerated approval of vaccines (4.1%, 10/244) among the public, and 32.78% (80/244) attributed limited infrastructure/vaccination centers/healthcare staff as the major challenge of a mass vaccination program with 71.72% (175/244) supporting the vehicle/home vaccination drives to meet the vaccination demand in the pandemic. Approximately 38.11% (93/244) blamed the lack of sufficient vaccine manufacturing sites in India as a major vaccine shortage. Almost 82% public knew that vaccines are incapable of providing lifelong immunity or conferring protection against multiple variants, with 34.83% desiring to get polyvalent vaccines that would provide immunity against multiple COVID-19 variants. A total of 57.37% knew about clinical research, believed that the vaccine/drug development process was slow in India (29.91%), that there was a lack of funds invested in COVID-19-related clinical research (62.29%), 47.95% felt no attention was given to the alternative system of medicines, 77.86% supported accelerated drug/vaccine approval in the pandemic. Around 64.34% of the study, participants knew about the available and approved COVID-19 treatment options, such as antiviral drugs, monoclonal antibodies and vaccines. Of the total 244 study participants, 98.36% believed that clinical research is important for science to progress. When asked about their willingness to participate in COVID-19 clinical research, only 40.57% agreed, while 29% opted for non-COVID-19 related clinical research, and 29% refused to participate in any kind of clinical research. Almost 88.93% refused to take medicines without approval by drug regulatory bodies, and 54.51% agreed to participate in a controlled human challenge research study during the pandemic. The majority were of the opinion that lack of financial support (35.24%) was the main hindrance to the conduct of clinical research in India and the reason for lagging behind other countries in research and development (64.34%). CONCLUSION: The survey provides insight into the public awareness and perception of the pandemic that has taught all the lessons for capacity building in automation, construction of robust medical infrastructure, and the need for future preparedness.

Objective: The study objective was to evaluate the prescription pattern and use of anti-seizure medications (ASMs) in patients with a seizure disorder and to evaluate if a change in the ASM dose had a beneficial effect on seizure control, observed through Therapeutic Drug Monitoring [TDM] level of ASMs. Methods: Details of anti-seizure medications with their therapeutic levels in the blood of patients with seizure disorder were analysed. Design: Hospital-based retrospective analysis of patient case records. Settings: Therapeutic Drug Monitoring OPD of a tertiary care public teaching hospital. Participants: Case records of 918 patients with seizure disorder from 2016-2021. Results: Data of men (53%) and women (47%) aged between 18-75 years was assessed About 62% (566/918) of patients were on levetiracetam, the most frequently prescribed anti-seizure medication. Whenever the ASMs dose was increased or decreased based on TDM levels, it was associated with a significant increase in the frequency of break-through seizures [OR- 5 (95% CI: 1.28-19.46)]. However, significant seizure control was observed when the patients were on the same maintenance dose of the anti-seizure medication [OR- 0.2 (95% CI: 0.06-0.63)]. Whenever an additional new anti-epileptic drug was prescribed or removed from the pre-existing anti-epileptic medications, it did not significantly impact seizure control. Conclusion: Individualising drug therapy and therapeutic drug monitoring for each patient, along with patient factors such as medication compliance, concomitant drug and disease history, and pharmacogenetic assessment, should be the ideal practice in patients with seizures for better seizure control. Funding: None declared.

Dry eye syndrome (DES) is a common disorder with rising incidence due to increased use of digital devices. While multiple treatment options are available, some are not efficacious or sometimes even safe for use in DES. This is particularly true for Fixed Dose Combinations (FDCs) that may contain ingredients having no rational for their use or may actually be harmful. Various committees appointed by the Government have reviewed several FDCs marketed in India and found some of them to be irrational and recommended for their removal. This paper discusses the contents of some of these FDCs marketed for DES with an aim to ensure that prescribers are mindful of their ingredients and whether there is adequate data about their efficacy and safety and prescribe them only if they consider them necessary for managing the patient.

Objectives: This study was conducted to evaluate the efficacy and safety of Cap. Torchnil & Tab. Febcin when given as add-on therapy to Covid19 positive patients with moderate disease. Material and methods: Following written informed consent, patients were randomized to receive Cap. Torchnil & Tab. Febcin in addition to standard of care (SOC) [Add-on Group] or only SOC [SOC Group] for 14 days. Effect on clinical symptoms, WHO Clinical Assessment scale, hospital stay duration, time to Covid negative report, Sp02 levels and biomarkers was assessed during admission and relapse rate, if any, post discharge for 3 months. Results: 193 patients were screened and 150 completed the study, 77 in Add-on Group and 73 in SOC Group. Improvement in Covid related symptoms, WHO Assessment scale, time to covid negative report and duration of hospital stay was observed earlier in Add-on Group. Statistically significant fall in biomarker levels viz. CPK, D-dimer and IL-6 values at Day 14 and LDH levels at Days 7 & 14 was observed in Add-on Group. Improvement in Sp02 levels was also seen earlier in Add-on Group. Only 2 patients complained of acidity. Post discharge, 91 patients (49 from Add-on group and 42 from SOC group) came for physical visits. All these patients were clinically stable with no evidence of relapse. Conclusion: The study results thus showed that Cap. Torchnil and Tab. Febcin were effective and safe when given as add-on therapy to SOC in the clinical management of patients with moderate Covid-19 disease.
RESUMO
Diabetic foot ulcer (DFU), if untreated, accounts for lower-limb amputations affecting patients' quality-of-life. Diperoxochloric acid (DPOCL) is known to heal DFU by its antibacterial and fibroblast stimulating activity. This was a phase 3, multicentre, randomized, double-blind, active-controlled, parallel-group study conducted to evaluate the efficacy and safety of topic solution of DPOCL compared with isotonic sodium chloride solution (ISCL). Adult patients with type 1 or 2 diabetes with random blood glucose levels of <250â mg/dL, with ≤ than three full-thickness foot ulcers were enrolled. Primary efficacy endpoint was complete wound closure and secondary was wound surface area. Adverse events were analyzed as safety endpoint. Of 311 enrolled patients, 289 were randomized 1:1 to DPOCL (139) and ISCL (150) treatment (10-weeks [8-Visits]). Percentage of patients with complete wound closure at visit-8, were significantly higher (P = .0156) in DPOCL arm (76% [105/139]) compared to ISCL (62% [93/150]) arm. At end-of-study, mean wound surface area in DPOCL arm (0.639â cm2) was significantly lower (P = .0209) compared to ISCL (0.818â cm2) arm. One death was reported in control arm which was not considered as treatment-related. No important safety finding were observed. Results indicate that, DPOCL can be considered as effective and safe treatment option for DFU compared to ISCL, although future confirmatory studies are warranted.
RESUMO
BACKGROUND: This study presents the results of the minimum inhibitory concentration (MIC) assay of a series of nosodes: namely Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Neisseria gonorrhoeae, and Candida albicans. Each was tested against its corresponding infection as well as cross infections. METHODS: In-vitro efficacy of polyvalent nosodes was tested using the MIC assay technique. The nosodes, namely C. albicans polyvalent nosode (35c, 100c), N. gonorrhoeae (35c), K. pneumoniae (35c, 100c), E. coli polyvalent nosode (35c, 100c) and Salmonella typhi polyvalent nosode (30c, 100c), were tested along with positive and negative controls. Nosodes were studied in different potencies and at 1:1 dilution. RESULTS: C. albicans polyvalent nosode 35c, 100c, N. gonorrhoeae 35c, and positive control amphotericin B showed inhibition of the growth of C. albicans species. K. pneumoniae 35c, E. coli polyvalent nosode 100c, and meropenem (positive control) showed inhibition of the growth of K. pneumoniae; this effect was not seen with ceftriaxone, ofloxacin and amoxicillin antibiotics. E. coli polyvalent nosode 30c in 10% alcohol (direct and dilution 1:1) and the positive controls ciprofloxacin, ofloxacin, and amoxicillin showed inhibition of the growth of E. coli. The S. typhi polyvalent nosode 30c in 10% alcohol showed inhibition of growth of S. typhi. CONCLUSION: This study reveals that the tested nosodes exhibited antibacterial potential against the corresponding micro-organisms and against other selected organisms studied using this assay.

BACKGROUND: This phase 2/3 immunobridging study evaluated the safety and immunogenicity of the ChAdOx1 nCoV-19 Coronavirus Vaccine (Recombinant) (SII-ChAdOx1 nCoV-19), manufactured in India at the Serum Institute of India Pvt Ltd (SIIPL), following technology transfer from the AstraZeneca. METHODS: This participant-blind, observer-blind study randomised participants 3:1 to SII-ChAdOx1 nCoV-19 or AZD1222 (ChAdOx1 nCoV-19) (immunogenicity/reactogenicity cohort) and 3:1 to SII-ChAdOx1 nCoV-19 or placebo (safety cohort). The study participants were enrolled from 14 hospitals across India between August 25 and October 31, 2020. Two doses of study products were given 4 weeks apart. The primary objectives were to demonstrate non-inferiority of SII-ChAdOx1 nCoV-19 to AZD1222 in terms of geometric mean titre (GMT) ratio of anti-SARS-CoV-2 spike IgG antibodies 28 days after the second dose (defined as lower limit of 95% CI >0·67) and to determine the incidence of serious adverse events (SAEs) causally related to SII-ChAdOx1 nCoV-19. The anti-spike IgG response was assessed using a multiplexed electrochemiluminescence-based immunoassay. Safety follow-up continued until 6 months after first dose. Trial registration: CTRI/2020/08/027170. FINDINGS: 1601 participants were enrolled: 401 to the immunogenicity/reactogenicity cohort and 1200 to the safety cohort. After two doses, seroconversion rates for anti-spike IgG antibodies were more than 98·0% in both the groups. SII-ChAdOx1 nCoV-19 was non-inferior to AZD1222 (GMT ratio 0·98; 95% CI 0·78-1·23). SAEs were reported in ≤ 2·0% participants across the three groups; none were causally related. A total of 34 SARS-CoV-2 infections were reported; of which 6 occurred more than 2 weeks after the second dose; none were severe. INTERPRETATION: SII-ChAdOx1 nCoV-19 has a non-inferior immune response compared to AZD1222 and an acceptable safety/reactogenicity profile. Pharmacovigilance should be maintained to detect any safety signals. FUNDING: SIIPL funded the contract research organisation and laboratory costs, while the site costs were funded by the Indian Council of Medical Research. The study vaccines were supplied by SIIPL and AstraZeneca.
RESUMO
BACKGROUND & AIMS: Nonalcoholic fatty liver disease (NAFLD) has multifactorial origin. Genetic and environmental factors lead to the biology of this complex disorder. In this study, we screened parents of cases with NAFLD and compared them with parents of cases without NAFLD to see its familial aggregation and the role of patatin-like phospholipase domain containing 3 (PNPLA3). METHOD: It was a cross-sectional study. Parents of probands with NAFLD and without NAFLD were screened with abdominal sonography, anthropometry, blood tests, transient elastography, and PNPLA3 polymorphism. RESULTS: We had enrolled 303 individuals: 51 probands with NAFLD, 50 probands without NAFLD, and their 202 parents. Parents of the NAFLD group had significantly higher metabolic risk factors as compared with parents of the non-NAFLD group. They had a significantly higher rate of fatty liver (P = 0.0001), mean serum aspartate aminotransferase levels (P = 0.011), mean serum alanine aminotransferase levels (P = 0.001),raised fasting and postprandial blood sugar levels, lower mean platelets (P = 0.033) and serum albumin levels (P = 0.005), and higher mean liver stiffness (P = 0.001) on transient elastography.Frequency of PNPLA3 polymorphism within NAFLD group was higher compared to the non-NAFLD group (mutant GG-13.3 vs 3.3%). Similarly, parents of NAFLD group had mutant GG in 15 % versus 5% in parents of non-NAFLD group, (P = 0.105, odds ratio 6), though it was not statistically significant but may be relevant. In this study, offsprings of parents with nonalcoholic steatohepatitis were likely to have GG homozygous allele. A NAFLD16 score based on parent's parameters was calculated to predict the probability of NAFLD occurrence in an overweight obese individual. CONCLUSION: Screening of parents of individuals with NAFLD will help in the identification of undiagnosed NAFLD cases and other metabolic risk factors among them as there is a familial aggregation of NAFLD. One can predict the occurrence of NAFLD in the next generation using the NAFLD16 score.
