RESUMO
BACKGROUND AND AIMS: Oral semaglutide has undergone global Phase 3 development programs named PIONEER and approved for therapeutic use in people with type 2 diabetes (T2D). We aim to systematically review the efficacy and safety of oral semaglutide in real-world settings. METHODS: We systematically searched the electronic databases of PubMed, Google Scholar, and ClinicalTrials.gov from inception until March 15, 2024, using several keywords with Boolean "AND". We retrieved all the available granular details of real-world studies (RWS). RESULTS: To date, results from four prospective and ten retrospective real-world studies of oral semaglutide in T2D are available. In prospective studies, the primary outcome of HbA1c reduction varied from -0.9 % to -1.6 %, weight loss varied from -4.7 kg to -8.2 kg and HbA1c target of <7 % was achieved in 30 %-64 % with oral semaglutide. In retrospective studies, HbA1c reduction varied from -0.4 % to -1.8 %, weight reduction varied from -1.4 to -9.0 kg, HbA1c target of <7 % was achieved in 32-64 %, and 30-41 % of people with T2D had ≥5 % weight loss with oral semaglutide. Gastrointestinal adverse events with oral semaglutide varied from 16 % to 50 % in prospective and 6 %-47 % in retrospective RWS. Overall, 0 %-18 % of patients had oral semaglutide discontinuation due to any cause. CONCLUSION: Oral semaglutide exhibited a reasonable reduction in HbA1c and weight in people with T2D, consistent with the findings from PIONEER trials. While no new safety issues emerged, the inherent limitations of RWS underscore the necessity of long-term investigations to comprehensively assess safety.

BACKGROUND AND AIMS: A systematic review and meta-analysis conducted by the World Health Organization (WHO) assessed the health outcomes of non-sugar sweeteners (NSS) in randomized controlled trials (RCTs) and prospective cohort studies (PCSs) and reported conflicting findings. We aim to decipher these conflicting findings in RCTs and PCSs by critically reviewing their results, comparing them with previous meta-analyses, and providing a simplified interpretation including the Indian perspective. METHODS: We critically reviewed the 210-page dossier of WHO including the full text of most of the key studies of NSS included in this meta-analysis and subsequently compared it with previous meta-analyses to identify similarities and differences to address a few key questions pertaining to health outcomes associated with NSS use in adults. RESULTS: Poor health outcomes are often associated with excess sugar intake. While NSS are typically consumed as a sugar replacement, benefits are conflicting. While RCTs found some benefits in the short term, PCSs found harm associated with NSS use in the long term. CONCLUSION: The 2022 WHO meta-analysis that assessed the health outcomes of NSS is the most robust and critically analyzed document available to date. Despite the absence of any strong conclusion that suggests NSS consumption increases the risk of cardio-metabolic disorders, no firm evidence also rejects this statement. NSS could be an attractive replacement for sugar in overweight/obese people in the short term, but long-term harm cannot be fully ruled out. We suggest avoiding consuming sugar and restricting NSS intake wherever possible until long-term studies confirm or refute these findings.

BACKGROUND AND AIMS: A recent systematic review and meta-analysis studied the effect of sodium-glucose cotransporter-2 inhibitors (SGLT2i) on new-onset diabetes (NOD) in adults with prediabetes having chronic kidney disease and heart failure. In light of other large randomized controlled trials (RCTs) of SGLT2i published after this meta-analysis that also reported the NOD outcome in adults with prediabetes, it is of interest to update the NOD outcome with SGLT2i. METHODS: A systemic search in the PubMed and Embase electronic database was made until March 31, 2023, using specific MeSH keywords following PRISMA protocol. Subsequently, we conducted a meta-analysis using the random effects model while applying the inverse variance-weighted averages of pooled logarithmic hazard ratio (HR). Heterogeneity was measured using Higgins I2 and Cochrane Q statistics and publication bias was evaluated by applying funnel plots. A sensitivity exclusion analysis was additionally made. RESULTS: This meta-analysis of five RCTs (N = 6752) found a significant reduction in NOD (HR 0.81; 95% CI, 0.69-0.94; P = 0.005) with SGLT2i in adults with prediabetes without any heterogeneity (I2 = 0%). CONCLUSIONS: SGLT2i has the potential to reduce NOD in adults with prediabetes. Since no effect on HbA1c reduction was seen in adults with prediabetes in all five RCTs included in this meta-analysis, it is conceivable that reduction in NOD is not related to the masking of blood glucose exerted by SGLT2i. However, only an adequately powered trial of SGLT2i in people with prediabetes with a sufficient wash-out period will confirm these findings.

An exclusive site for local drug delivery is the vagina, especially for vaginal infections. The fungus Candida albicans causes vaginal infection known as vulvovaginal candidiasis, a highly prevalent and recurrent gynaecological disease among women. Vaginal candidiasis affects over 75% of women at a certain point in their life and has a recurrence rate of 40-50%. Medicinal plants provide some very effective phytoconstituents which when delivered as nanosystems have enhanced therapeutic action and efficacy by alteration in their characteristics. Antifungal drugs are used to treat these conditions, alternative medicine is required for prophylaxis and improved prognosis. The current review focuses on the research carried out on various nanocarrier-based approaches and essential oil-based formulations for vaginal candidiasis.
The vagina is a part of a woman's body that can sometimes get sick from a fungus called Candida albicans. This sickness is called thrush, and it's very common. More than 75% of women will get it at some point, and it might come back again after it's gone. There are medicines that can help, but some plants can also be used to make powerful medicine that can heal the sickness from tiny particles called 'nanosized carriers'. Scientists are studying different ways to give the medicine to the sick area from these plants.

OBJECTIVE: The cardiovascular (CV) and renal benefits of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in people with type 2 diabetes are well known. However, similar beneficial effects of SGLT2i in combination with dipeptidyl peptidase-4 inhibitors (DPP4i) are unknown. It is of interest to explore a trial-level meta-analysis to fill this knowledge gap. METHODS: A literature search was conducted in the PubMed and Embase databases until January 31, 2023. All CV outcome trials (CVOTs) reporting the CV and renal outcomes of SGLT2i with or without background DPP4i therapy against the placebo were retrieved. A meta-analysis was subsequently conducted by applying the inverse variance-weighted averages of pooled logarithmic hazard ratio using primarily random-effects analysis. RESULTS: This meta-analysis showed that the beneficial 3-point major adverse cardiovascular events composite (3 CVOTs; N = 32 418), the composite of CV death or heart failure hospitalization (hHF) (4 CVOTs; N = 37 687), hHF (3 CVOTs; N = 27 545), CV death (4 CVOTs; N = 34 565), and renal outcomes (2 CVOTs; N = 25 406) with SGLT2i were similar with or without background DPP4i therapy against the placebo (Pheterogeneity = .71, .07, .87, .72, and .25; respectively). However, against the placebo, the summary estimates for the 3-point major adverse cardiovascular events composite, hHF, and renal outcomes were stronger with SGLT2i alone, whereas the summary estimates for CV death or hHF composite were larger with SGLT2i with background DPP4i therapy. CONCLUSION: Beneficial CV and renal effects of SGLT2i are similar against the placebo regardless of background DPP4i therapy.

BACKGROUND: Globally, growth monitoring and promotion (GMP) of infants and young children is a fundamental component of routine preventive child health care; however, programs have experienced varying degrees of quality and success with enduring challenges. The objective of this study was to describe implementation of GMP (growth monitoring, growth promotion, data use, and implementation challenges) in two countries, Ghana and Nepal, to identify key actions to strengthen GMP programs. METHODS: We conducted semi-structured key informant interviews with national and sub-national government officials (n = 24), health workers and volunteers (n = 40), and caregivers (n = 34). We conducted direct structured observations at health facilities (n = 10) and outreach clinics (n = 10) to complement information from interviews. We coded and analyzed interview notes for themes related to GMP implementation. RESULTS: Health workers in Ghana (e.g., community health nurses) and Nepal (e.g., auxiliary nurse midwives) had the knowledge and skills to assess and analyze growth based on weight measurement. However, health workers in Ghana centered growth promotion on the growth trend (weight-for-age over time), whereas health workers in Nepal based growth promotion on measurement from one point in time to determine whether a child was underweight. Overlapping challenges included health worker time and workload. Both countries tracked growth-monitoring data systematically; however, there was variation in growth monitoring data use. CONCLUSION: This study shows that GMP programs may not always focus on the growth trend for early detection of growth faltering and preventive actions. Several factors contribute to this deviation from the intended goal of GMP. To overcome them, countries need to invest in both service delivery (e.g., decision-making algorithm) and demand generation efforts (e.g., integrate with responsive care and early learning).

BACKGROUND & AIMS: Imeglimin is a novel new oral compound recently approved for treating type 2 diabetes (T2D) in India. We conducted a systematic review and meta-analysis to evaluate the efficacy of imeglimin in people with T2D in the approved dose of 1000 mg twice daily (BID). METHODS: We systematically searched the database of PubMed until December 20, 2022, and retrieved all published double-blind, randomized, placebo-controlled trials (RCTs) conducted with imeglimin 1000 mg BID, using appropriate keywords and MeSH terms. A meta-analysis was conducted to study the HbA1c lowering effect of imeglimin 1000 mg BID in people with T2D using the Comprehensive meta-analysis (CMA) software Version 3, Biostat Inc. Englewood, NJ, USA. RESULTS: Of the seven Phase 2 studies and three Phase 3 studies conducted so far, only three published double-blind RCTs have reported the efficacy and safety of imeglimin 1000 mg BID against the placebo. Our meta-analysis using the random-effects model from two monotherapy studies (n = 360) showed imeglimin 1000 mg BID reduce HbA1c significantly (Δ -0.9%, 95% Confidence Interval [CI], -1.1 to -0.74%; P < 0.0001) against the placebo, without any heterogeneity (I2 = 0%). The pooled meta-analysis from all three RCTs (n = 574) found a significant reduction in HbA1c with imeglimin 1000 mg BID (Δ -0.79%; 95% CI, -1.00 to -0.59%; P < 0.0001) compared to placebo with high heterogeneity. CONCLUSIONS: This meta-analysis found a significant HbA1c lowering effect of imeglimin in people with T2D with an acceptable tolerability profile. Still, larger and longer studies are needed.

BACKGROUND & AIMS: Finerenone is a novel non-steroidal mineralocorticoid antagonist (MRA) recently approved for the treatment of chronic kidney disease (CKD) in people with type 2 diabetes (T2D). We aim to conduct a systematic review of finerenone to know the efficacy and safety of finerenone in CKD with or without T2D. METHODS: A systematic search in the electronic database of PubMed and Google Scholar was made from inception until September 09, 2022, using several MeSH keywords related to finerenone. Ongoing trials were additionally searched from ClinicalTrials.Gov. RESULTS: Five phase 2 and three phase 3, randomized, double-blind, placebo- or active-controlled studies of finerenone have been published to date and several other randomized and real-world studies of finerenone are currently undergoing. CONCLUSIONS: In short-term studies in patients with CKD and reduced ejection heart failure, with or without T2D, finerenone 20 mg appears to have a better renal outcome compared with spironolactone and a better mortality outcome compared with eplerenone, with significantly lesser hyperkalemia compared to both spironolactone and finerenone. In long-term studies in patients with CKD and T2D, finerenone 10/20 mg significantly reduces the progression of renal disease and reduced CV endpoints (especially heart failure hospitalization) compared to placebo. Finerenone has no effect on HbA1c, body weight, and sexual side effects including gynecomastia, and has only a modest effect on blood pressure. However, hyperkalemia leading to drug withdrawal was significantly higher with finerenone compared to placebo. Safety data in real-world settings is a pressing priority.

BACKGROUND AND AIMS: Insulin icodec is currently the most advanced candidate insulin suitable for once-weekly administration. We aim to conduct a systematic review of the literature to find out the efficacy and safety of insulin icodec in patients with diabetes mellitus. METHODS: We systematically searched the electronic database of PubMed, and Google Scholar from inception until August 20, 2022, using MeSH keywords. Ongoing trials of insulin icodec were additionally searched from the ClinicalTrials.Gov. We retrieved all the available granular details of phase 1 to phase 3 studies of insulin icodec in both type 1 and type 2 diabetes. RESULTS: Phase 1 study showed insulin icodec having a half-life of 196 h (>1 week) while a steady state is achieved after 3 to 4 weekly injections. Phase 2 studies compared once-weekly icodec to insulin glargine (U-100) and found a similar glucose control with no significantly greater hypoglycemia risks. Top-line results from the five phase 3 studies reported better glucose control with once-weekly icodec compared to both once-daily insulin glargine (ONWARDS 1) and once-daily degludec (in both ONWARDS 2 and 4) with similar rates of hypoglycemia in type 2 diabetes, although there was a higher hypoglycemic event with insulin icodec in type 1 diabetes (ONWARDS 6) compared to once-daily degludec despite a similar glycemic control. CONCLUSION: A brighter prospect of once-weekly insulin icodec is on the card in particular in type 2 diabetes in terms of reducing injection pricks by >85% vs. once-daily basal insulin analogs, although few unknowns still exist.

BACKGROUND AND AIMS: Molnupiravir is a newer oral antiviral drug that has recently received emergency use authorization (EUA) in USA, UK and India. We aim to conduct an update on our previous systematic review to provide practical clinical guideline for using molnupiravir in patients with COVID-19. METHODS: We systematically searched the electronic database of PubMed, MedRxiv and Google Scholar until January 5, 2022, using key MeSH keywords. RESULTS: Final result of phase 3 study in 1433 non-hospitalized COVID-19 patients showed a significant reduction in composite risk of hospital admission or death (absolute risk difference, -3.0% [95% confidence interval {CI}, -5.9 to -0.1%]; 1-sided P = 0.02) although with a non-significant 31% relative risk reduction (RRR). RRR for death alone was 89% (95% CI, 14 to 99; P-value not reported). Number needed to treat to prevent 1 death or 1 hospitalization or death composite appears to be closely competitive to other agents having EUA in people with COVID-19. However, cost-wise molnupiravir is comparatively cheaper compared to all other agents. CONCLUSION: Molnupiravir could be a useful agent in non-pregnant unvaccinated adults with COVID-19 who are at increased risk of severity including hospitalization. However, it is effective only when used within 5-days of onset of symptoms. A 5-days course seems to be safe without any obvious short-term side effects.

BACKGROUND AND AIMS: Molnupiravir is a newer oral antiviral drug that has recently been tested in COVID-19. We aim to conduct a systematic review of literature to find out the efficacy and safety of molnupiravir in patients with COVID-19. METHODS: We systematically searched the electronic database of PubMed, MedRxiv and Google Scholar from inception until October 15, 2021, using MeSH keywords. Ongoing trials of molnupiravir in COVID-19 were additionally searched from the ClinicalTrials.Gov and ctri.nic.in/Clinicaltrials. We retrieved all the available granular details of phase 1 to 3 studies of molnupiravir in COVID-19. Subsequently we reviewed the results narratively. RESULTS: Two phase 1 double-blind, randomized, placebo-controlled (DBRPC) studies of molnupiravir showed that 1600 mg daily dose is safe and tolerable, without any serious adverse events up to 5.5 days. One phase 2 DBPRC study found significantly lower time to clearance (RNA negativity) with molnupiravir 800 mg twice daily compared to the placebo (log-rank p value = 0.013) in mild to moderate COVID-19. Interim report of one phase 3 DBRPC study in non-hospitalized COVID-19 found a significant reduction in the risk of hospital admission or death by 50% (p = 0.0012). However, no significant benefit was observed with molnupiravir in the later stage of moderate to severe COVID-19. CONCLUSION: Molnupiravir is first oral antiviral drug to demonstrate a significant benefit in reducing hospitalization or death in mild COVID-19 and could be an important weapon in the battle against SARS-CoV-2. However, its role in moderate to severe COVID-19 is questionable and more studies are needed.

Examining the role of environmental enteric dysfunction (EED) in child growth requires noninvasive, field-appropriate biomarkers. Alternatives to the traditionally used lactulose:mannitol (L:M) test have been explored, but few studies have compared the L:M test to host fecal mRNA transcripts. The objectives of this study were to examine whether 1) host fecal mRNA transcripts could predict presence and severity of EED, measured using the L:M test, and 2) EED modifies the effect of specialized nutritious foods (SNFs) on recovery from moderate acute malnutrition (MAM). This substudy was nested within a cluster randomized trial comparing four SNFs in the treatment of MAM among children 6 to 59 months in Sierra Leone. EED was assessed at enrollment using the L:M test and 15 host fecal mRNA transcripts on 522 children. Recovery from MAM was defined as achieving mid-upper arm circumference ≥ 12.5 cm within 12 weeks of supplementation. Random forest classification models were used to examine prediction of presence and severity of EED by host fecal mRNA transcripts. Logistic regression was used to test for effect modification by L:M test variables including % lactulose excreted (%L). Eight host fecal mRNA transcripts (AQP9, REG3A, IFI30, DECR1, BIRC3, SELL, PIK3AP1, DEFA6) identified EED (%L ≥ 0.2) and severe EED (%L ≥ 0.45) with high sensitivity and specificity. The L:M test variables did not modify the effect of SNFs on recovery from MAM. In this study, we found host fecal mRNA transcripts that could be biomarkers of EED but did not find EED to modify the effect of SNFs on MAM treatment.

BACKGROUND: Measures that better describe "healthy" and sustainable recovery during nutritional treatment of children with moderate acute malnutrition (MAM) are needed. OBJECTIVES: We compared changes to body composition among children receiving 1 of 4 specialized nutritious food (SNFs) during treatment of MAM and by recovery and relapse outcomes. METHODS: The study was nested within a prospective, cluster-randomized, community-based, cost-effectiveness trial assessing 4 SNFs to treat children aged 6-59 mo with MAM [midupper arm circumference (MUAC) ≥11.5 cm and <12.5 cm without bipedal edema] in Sierra Leone. Biweekly SNF rations (1 of 3 fortified-blended foods or a lipid-based nutrient supplement) were given until children recovered (MUAC ≥12.5 cm), or up to 7 rations (â¼12 wk). Deuterium dilution was used to estimate fat-free mass (FFM) and fat mass (FM) at enrollment and after 4 wk of treatment to ensure similar treatment exposure among the participants. Another MUAC measurement was performed among recovered children 4 wk after program exit to determine whether recovery was sustained. ANOVA, paired t tests, and linear regression models were used to determine significant differences in changes from baseline to 4 wk. RESULTS: Among 312 analyzed participants, mean baseline weight comprised â¼80% FFM; mean weight gained after 4 wk comprised â¼82% FFM. Changes in FM and FFM among 4 SNFs were similar. Children who recovered gained more weight (241%), FFM (179%), and weight-for-height z score (0.44 compared with 0) compared with those who did not recover; sustainers gained 150% more weight. FM gains were positive among recovered children and sustainers, as well as negative among those who did not recover or sustain recovery, but not significantly different. CONCLUSIONS: Four SNFs had similar effects on body composition in children after 4 wk of treatment for MAM, showing a healthy pattern of weight gain, the majority being FFM. Differential responses to treatment underscore a need for further research to provide targets for healthy, sustainable recovery. This trial was registered at clinicaltrials.gov as NCT03146897.

BACKGROUND: Environmental enteric dysfunction (EED) may influence growth during and recovery from moderate acute malnutrition (MAM), however, biomarkers to assess these relations have yet to be identified. OBJECTIVES: The objectives of this study were to: 1) develop a score for EED based on host fecal mRNA transcripts, 2) compare biomarkers of EED with each other, and 3) examine associations between the EED biomarkers and recovery from MAM and growth outcomes. METHODS: In a cohort of 520 Sierra Leonean MAM children, biomarkers of EED included the lactulose: mannitol (L: M) test, 15 host fecal mRNA transcripts, and host fecal proteins [α-1-antitrypsin (AAT), myeloperoxidase (MPO), neopterin (NEO)]. Anthropometry data were also collected and z scores were computed for length-for-age (LAZ) and weight-for-length (WLZ). Recovery from MAM was defined as midupper arm circumference ≥12.5 cm. Factor analysis was used to identify EED scores using the mRNA transcripts, and mixed effects regression was conducted to test for associations. RESULTS: The 15 host fecal mRNA transcripts were clustered into 3 scores: gut inflammation (GI) score, gut structure (GS) score, and gut defense (GD) score. We found agreement between certain inflammation markers (GI score and MPO), and permeability markers (GS score and AAT; AAT and the L: M excretion ratio). Antimicrobial gut defense (GD score) was inversely associated with percent lactulose excreted, a measure of intestinal permeability. LAZ (ß: -0.08; 95% CI: -0.14, -0.02) and WLZ (ß: -0.03; 95% CI: -0.06, -0.01) were negatively associated with GI score. A high GD score (ß: 0.36; 95% CI: 0.08, 0.64) and low AAT (ß: -1.35; 95% CI: -2.35, -0.36) were associated with recovery from MAM. CONCLUSIONS: Scores derived from host fecal mRNA transcript variably correlated with the L: M test and host fecal proteins. Markers of intestinal inflammation, permeability, and defense were associated with growth outcomes and recovery from MAM.

AIM: To estimate the prevalence of both cardiometabolic and other co-morbidities in patients with COVID-19, and to estimate the increased risk of severity of disease and mortality in people with co-morbidities. MATERIALS AND METHODS: Medline, Scopus and the World Health Organization website were searched for global research on COVID-19 conducted from January 2019 up to 23 April 2020. Study inclusion was restricted to English language publications, original articles that reported the prevalence of co-morbidities in individuals with COVID-19, and case series including more than 10 patients. Eighteen studies were selected for inclusion. Data were analysed using random effects meta-analysis models. RESULTS: Eighteen studies with a total of 14 558 individuals were identified. The pooled prevalence for co-morbidities in patients with COVID-19 disease was 22.9% (95% CI: 15.8 to 29.9) for hypertension, 11.5% (9.7 to 13.4) for diabetes, and 9.7% (6.8 to 12.6) for cardiovascular disease (CVD). For chronic obstructive pulmonary disease (COPD), chronic kidney disease (CKD), cerebrovascular disease and cancer, the pooled prevalences were all less than 4%. With the exception of cerebrovascular disease, all the other co-morbidities presented a significantly increased risk for having severe COVID-19. In addition, the risk of mortality was significantly increased in individuals with CVD, COPD, CKD, cerebrovascular disease and cancer. CONCLUSIONS: In individuals with COVID-19, the presence of co-morbidities (both cardiometabolic and other) is associated with a higher risk of severe COVID-19 and mortality. These findings have important implications for public health with regard to risk stratification and future planning.

BACKGROUND & AIMS: Remdesivir is a broad spectrum anti-viral drug that has shown to inhibit SARS-CoV-2, in vitro and in vivo. In absence of any effective treatment for SARS-CoV-2 infection (COVID-19), remdesivir has been tried for a compassionate use in severe COVID-19. Newer randomized controlled studies that have recently become available, showed a mixed result. We aimed to systematically search the literature to understand the pharmacology and clinical effects of remdesivir in patients with COVID-19. METHODS: We systematically searched the PubMed, ClinicalTrial.Org and MedRxiv database up till May 5, 2020 using specific key words such as "Remdesivir" or 'GS-5734â³ AND "COVID-19" or "SARS-CoV-2" and retrieved all the article published in English language, that have reported the pharmacology and the clinical outcomes of remdesivir in patients with COVID-19. RESULTS: Initial compassionate use of remdesivir has shown a fairly good result, but difficult to quantify, in the absence of control arm. While the very first double-blind, placebo-controlled, randomized trial conducted in Wuhan, did not find any significant benefit compared to the control, the preliminary result of another similar multi-country trial has shown a significant faster time to recovery but without any difference in mortality. CONCLUSIONS: Remdesivir has shown a mixed result in patients with COVID-19 with an acceptable side effect. However, jury is still out while awaiting the results from the forthcoming trials.

BACKGROUNDS AND AIMS: The role of hydroxychloroquine (HCQ) in the treatment of COVID-19 is not fully known. We studied the efficacy of HCQ compared to the control in COVID-19 subjects on - a. viral clearance measured by reverse transcriptase polymerase chain reaction (RT-PCR) and, b. death due to all cause. METHODS: PubMed, Scopus, Cochrane and MedRxiv database were searched using the specific keywords up to April 30, 2020. Studies that met our objectives were assessed for the risk of bias applying various tools as indicated. Three studies each that reported the outcome of viral clearance by RT-PCR and death due to all cause, were meta-analyzed by applying inverse variance-weighted averages of logarithmic risk ratio (RR) using a random effects model. Heterogeneity and publication bias were assessed using the I2 statistic and funnel plots, respectively. RESULTS: Meta-analysis of 3 studies (n = 210) on viral clearance assessed by RT-PCR showed no benefit (RR, 1.05; 95% CI, 0.79 to 1.38; p = 0.74), although with a moderate heterogeneity (I2 = 61.7%, p = 0.07). While meta-analysis of 3 studies (n = 474) showed a significant increase in death with HCQ, compared to the control (RR, 2.17; 95% 1.32 to 3.57; p = 0.002), without any heterogeneity (I2 = 0.0%, p = 0.43). CONCLUSIONS: No benefit on viral clearance but a significant increase in mortality was observed with HCQ compared to control in patients with COVID-19.

BACKGROUND AND AIMS: The last two decades have experienced the outbreaks of three different coronaviruses in the different parts of the world namely; Severe acute respiratory syndrome cornonavirus-1 (SARS-CoV-1), Middle East respiratory syndrome (MERS-CoV) and Severe acute respiratory syndrome cornonavirus-2 (SARS-CoV-2). We aimed to delineate the differences in viral dynamics and clinical features between them and tried to focus on every basic details of SARS-COV-2 (COVID-19) that every health care provider must know. METHODS: We systematically searched the PubMed database up till April 2, 2020 and retrieved all the articles published on SARS-CoV-2, SARS-CoV-1, MERS-CoV that dealt with viral dynamics. RESULTS: Ample data is available to suggest the differences in etiology, transmission cycle, diagnosis, genetics, hosts, reproductive rates, clinical features, laboratory diagnosis and radiological features between SARS-CoV-1, MERS-CoV and SARS-CoV-2. CONCLUSION: Although SARS-CoV-2 (COVID-19) is more infectious than SARS-CoV-1 and MERS-CoV, most infections are generally mild and self-limiting. However, case-fatality rates are very high in patients with COVID-19 with comorbidities, compared to SARS-CoV-1 and MERS-CoV.

BACKGROUND AND AIMS: No drugs are currently approved for Coronavirus Disease-2019 (COVID-19), although some have been tried. In view of recent studies and discussion on chloroquine and hydroxychloroquine (HCQ), we aimed to review existing literature and relevant websites regarding these drugs and COVID-19, adverse effects related to drugs, and related guidelines. AIMS AND METHODS: We systematically searched the PubMed database up till March 21, 2020 and retrieved all the articles published on chloroquine and HCQ and COVID-19. RESULTS: Two small human studies have been conducted with both these drugs in COVID-19, and have shown significant improvement in some parameters in patients with COVID-19. CONCLUSION: Considering minimal risk upon use, a long experience of use in other diseases, cost-effectiveness and easy availability across India, we propose that both these drugs are worthy of fast track clinical trial for treatment, and may be carefully considered for clinical use as experimental drugs. Since HCQ has been approved for treatment of diabetes in India, it should be further researched in diabetes and COVID-19, a subgroup where significant mortality has been shown.
