RESUMEN

Only a few treatments are approved for coronavirus disease-2019 (COVID-19) infections, with continuous debate about their clinical impact. Repurposing antiviral treatments might prove the fastest way to identify effective therapy. This trial aimed to evaluate the efficacy and safety of sofosbuvir (SOF) plus daclatasvir (DCV) or ravidasvir (RDV) added to standard care (SOC) for patients with moderate and severe COVID-19 infection. Multicentre parallel randomized controlled open-label trial. One hundred and twenty eligible patients with moderate and severe COVID-19 infection were randomized to one of the study arms. Ten days of treatment with SOF plus DCV or RDV in addition to the standard of care compared to SOC. Follow up in 7 days. Sum of the counted symptoms at 7 and 10 days, mean change in oxygen saturation level, viral negativity, and rate of intensive care unit (ICU) admission. Compared to SOC, the SOF-DCV group experienced a significantly lower sum of the counted symptoms (fever, headache, generalized aches, or respiratory distress) combined with no evidence of deterioration (ICU admission and mechanical ventilation) on Days 7 and 10 of treatment. Oxygen saturation also significantly improved among the SOF-DCV group compared to SOC starting from Day 4. The study also showed positive trends regarding the efficacy of SOF-DCV with a lower incidence of mortality. On the other hand, adding SOF-RDV to SOC did not show significant improvements in endpoints. The results support the efficacy and safety of SOF-DCV as an add-on to SOC for the treatment of moderate to severe COVID-19 infections.

RESUMEN

OBJECTIVES: Dual sofosbuvir/daclatasvir (SOF/DCV) therapy is currently recommended by the European Association for Study of Liver (EASL) as an option for the treatment of chronic hepatitis C virus (HCV) infection in adults for all genotypes; however, it is still not considered for patients younger than 18 years old. We aimed to test safety and efficacy of SOF/DCV in adolescent patients 12 to 17 years old with chronic HCV, genotype 4 infection. METHODS: We conducted a prospective, uncontrolled, open-label multicenter study. A total of 30 chronic HCV-infected adolescents, aged from 12 to 17 years old were included and treated with dual SOF/DCV for 12 weeks. Patients were monitored throughout the treatment and follow-up period for safety and efficacy outcome measures including the sustained virologic response 12 (SVR12) rate. RESULTS: The intention-to-treat (ITT) SVR12 rate was 29 of 30 (96.7%; 95% confidence interval [CI] 83.3%-99.4%). The only patient who did not achieve SVR12 was lost to follow-up after showing viral negativity at the end of treatment (EOT) visit. Whereas all the remaining 29 patients (100%, 95% CI 88.3%-100%) who completed the follow-up visits achieved SVR12. All patients showed normalized liver enzymes with normal hematological, liver and renal function tests at the end of the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study. CONCLUSIONS: SOF/DCV combined therapy could be a safe and effective treatment in adolescent patients 12 to 17 years old with chronic HCV genotype 4 infection.

RESUMEN

BACKGROUND & AIMS: Although treatment of hepatitis C virus (HCV) and HCV-genotype-4 (GT4) has become very effective, it remains very expensive, and affordable options are needed, especially in limited resource countries. The aim of this study was to assess the efficacy and safety of the combination of ravidasvir (an NS5A inhibitor) and sofosbuvir to treat patients with chronic HCV-GT4 infection. METHODS: A total of 300 patients with HCV-GT4 infection were recruited in three groups: treatment-naïve patients with or without compensated Child-A cirrhosis (Group 1); interferon-experienced patients without cirrhosis (Group 2); and interferon-experienced patients with cirrhosis (Group 3). Groups 1 and 2 received ravidasvir 200 mg QD plus sofosbuvir 400 mg QD for 12 weeks and were randomized 1:1 to treatment with or without weight-based ribavirin. Group 3 patients received ravidasvir plus sofosbuvir with ribavirin and were randomized 1:1 to a treatment duration of 12 weeks or 16 weeks. The primary endpoint was sustained virologic response at 12 weeks post-treatment (SVR12). RESULTS: A total of 298 patients were enrolled: 149 in Group 1, 79 in Group 2 and 70 in Group 3. SVR12 was achieved in 95.3% of all patients who started the study, including 98% of patients without cirrhosis and 91% of patients with cirrhosis, whether treatment-naïve or interferon-experienced. Ribavirin intake and history of previous interferon therapy did not affect SVR12 rates. No virologic breakthroughs were observed and the study treatment was well tolerated. CONCLUSIONS: Treatment with ravidasvir plus sofosbuvir, with or without ribavirin, was well tolerated and associated with high sustained virologic response rate for HCV-GT4 infected patients with and without cirrhosis, regardless of previous interferon-based treatments. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier: NCT02371408. LAY SUMMARY: This study evaluated efficacy and safety of the new oral hepatitis C drug ravidasvir in combination with the approved oral drug sofosbuvir in 298 patients infected with hepatitis C type 4. Our results showed that treatment with ravidasvir plus sofosbuvir, with or without ribavirin, was well tolerated and associated with high response rate in patients with and without cirrhosis.

RESUMEN

COVID-19 is a pandemic disease caused by SARS-CoV-2, which is an RNA virus similar to the hepatitis C virus (HCV) in the replication process. Sofosbuvir/ledipasvir is an approved drug to treat HCV infection. This study investigates the efficacy of Sofosbuvir/ledipasvir as a treatment for patients with moderate COVID-19 infection. This is a single-blinded parallel-randomized controlled trial. The participants were randomized equally into the intervention group that received Sofosbuvir/ledipasvir (S.L. group), and the control group received Oseltamivir, Hydroxychloroquine, and Azithromycin (OCH group). The primary outcomes were the cure rate over time and the incidence of serious adverse events. The secondary outcomes included the laboratory findings. 250 patients were divided equally into each group. Both groups were similar regarding gender, but age was higher in the S.L. group (p=0.001). In the S.L. group, 89 (71.2%) patients were cured, while only 51 (40.8%) patients were cured in the OCH group. The cure rate was significantly higher in the S.L. group (RR=1.75, p<0.001). Kaplan-Meir plot showed a considerably higher cure over time in the S.L. group (Log-rank test, p=0.032). There were no deaths in the S.L. group, but there were six deaths (4.8%) in the OCH group (RR=0.08, p=0.013). Seven patients (5.6%) in the S.L. group and six patients (4.8%) in the OCH group were admitted to the intensive care unit (ICU) (RR=1.17, P=0.776). There were no significant differences between treatment groups regarding total leukocyte and neutrophils count, lymph, and urea. Sofosbuvir/ledipasvir is suggestive of being effective in treating patients with moderate COVID-19 infection. Further studies are needed to compare Sofosbuvir/ledipasvir with new treatment protocols.

RESUMEN

BACKGROUND: Dramatic advances in hepatitis C virus (HCV) treatment were witnessed with the introduction of direct-acting antivirals (DAAs). Generic DAAs with remarkable efficacy and good safety profiles are currently manufactured by local pharmaceutical companies in Egypt. METHODS: In the real-world setting, of a total of 367 patients chronically infected with HCV, 289 (277 treatment-naïve and 12 treatment-experienced) patients were enrolled. Approximately 15% of the patients were coinfected with hepatitis B virus (HBV). Patients were treated with sofosbuvir+daclatasvir with or without ribavirin for 12 or 24 wk as the standard of care. HBV DNA levels were monitored throughout the study. RESULTS: A sustained virologic response at 12 wk (SVR12) was achieved in 98.3% of the patients. All non-responders were treatment-naïve and the response rate among treatment-experienced patients was 100.0%. Elevated α-fetoprotein and treatment with sofosbuvir+daclatasvir+ribavirin for 6 mo were predictors of non-response (OR [95% CI] = 1.06 [1.02 to 1.1] and 15.9 [1.8 to 136.2]; p<0.05, respectively). No HBV reactivation was noticed throughout the treatment and follow-up periods in HCV/HBV coinfected patients. CONCLUSION: The present real-world findings add to the evidence for the efficacy of generic DAAs for the treatment of patients infected with HCV. HBV reactivation is unlikely to occur in those coinfected with HBV. Although liver cirrhosis affected the outcome, pretreatment liver chemistry did not seem to correlate with the results of treatment.

RESUMEN

BACKGROUND: Diabetic foot ulcer (DFU) is the main risk factor for nontraumatic lower-limb amputation. We hypothesized that by reversing the offending local tissue factors resulting from the low tissue supply of oxygen, inefficient fuel metabolism and acidosis, we can eradicate the infection and help to promote healing. This might be enhanced with the help of an innovated local preparation (PEDYPHAR®) through its enriched alkaline ointment base and the regenerating growth factors of Royal Jelly (RJ) plus the antimicrobial, immune-modulatory nutritional and other biochemical properties of RJ and Panthenol. We conducted this study to test the safety and efficacy of PEDYPHAR ointment as an adjuvant in limb salvage management for patients with limb-threatening diabetic foot wounds. METHODS: A prospective, randomized, controlled open-label study design with a mean follow-up period of 12 weeks. One hundred and nineteen eligible patients with diabetic foot wounds presenting to 3 outpatient clinics in Egypt were randomized to be treated with the local application of either PEDYPHAR or Panthenol ointment under dressing after conservative debridement of necrotic tissue and irrigation with warm normal saline. RESULTS: At the end of the 12-week follow-up period, PEDYPHAR showed a higher rate of complete healing of limb-threatening wounds in the intent-to-treat population, 11 of 34 (32.4%) in PEDYPHAR-treated group versus 3/25 (12%) in the Panthenol-treated (control) group (p=0.034* [*indicates it is statistically significant]). CONCLUSION: We can conclude that PEDYPHAR could be an effective and safe conservative local adjuvant treatment for cases of diabetic foot infection.Registration number in ClinicalTrials.gov: NCT01531517.

RESUMEN

Negative effects on growth indices had been reported in children treated with interferon for chronic viral hepatitis. Forty chronic hepatitis C virus-infected adolescents, 12-17 years of age, were treated with sofosbuvir/daclatasvir therapy for 12 weeks. The intent-to-treat sustained virologic response rate at 12 weeks after end of treatment was 39/40 (97.5%). Unlike interferon-based therapy, we did not detect significant negative effects on linear growth or weight. Contrarily, a trend to increased appetite and insignificant weight gain was observed, but further larger studies are needed to confirm. See Video-Abstract, http://links.lww.com/ASAIO/A381.

RESUMEN

BACKGROUND: Childhood cancer survivors are potentially at a higher risk of infection with hepatitis C virus (HCV). The effects of all-oral direct-acting antiviral therapy (DAA) on both the HCV infection as well as the state of cancer remission have not been well investigated in this population. AIM: To test the effects of dual sofosbuvir/daclatasvir (SOF/DCV) therapy in the treatment of chronic HCV in survivors of hematologic malignancy in pediatric age group. METHODS: We conducted a prospective, uncontrolled, open-label multicenter study. A total of 20 eligible, chronic HCV, genotype-4, infected children who had been in continuous complete remission from hematologic cancer (leukemia/lymphoma) for at least one year were included in the study. All patients were treated with combined SOF/DCV for 12 wk. Patients were monitored throughout the study till 12 wk after end of treatment for safety and efficacy outcomes including the sustained virologic response 12 (SVR12) rate, hematological indices, liver and kidney functions. RESULTS: The intent-to-treat SVR12 rate was 20 of 20 (100%; 95%CI: 84%-100%). All patients showed normalized liver enzymes from week-4. All hematological indices, liver and kidney functions were kept normal throughout the study. No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study. CONCLUSION: SOF/DCV combined therapy could be used safely and effectively in the treatment of chronic HCV genotype-4 infection in leukemia/lymphoma treated children. No relapses were detected during treatment and throughout the follow up period for either the original malignant disease or the HCV infection.

RESUMEN

Mass production of low-cost, generic direct-acting antivirals (DAAs) will be required to achieve targets of eliminating hepatitis C (HCV) by 2030. The pharmaceutical companies Gilead and Bristol-Myers Squibb have granted voluntary licences (VLs) to generic companies to mass produce the DAAs sofosbuvir and daclatasvir at low cost. However, generic manufacturers need to demonstrate bioequivalent pharmacokinetics for their DAAs, compared to the originator versions, to fulfil World Health Organization standards for prequalification. The aim of this study was to determine whether generic forms of sofosbuvir and daclatasvir had bioequivalent pharmacokinetics to the originator versions. Generic companies were contacted for results of bioequivalence studies with sofosbuvir and daclatasvir, two of the most widely used DAAs in the developing world. Data on maximum concentration (Cmax) and area under the curve (AUC) were compiled from five generic companies. Pre-specified limits for the 90% confidence intervals were 80-125% of the originator pharmacokinetic concentrations for AUC, and 69-145% for Cmax. The pharmacokinetics of generic sofosbuvir and daclatasvir were shown to be bioequivalent to the originator versions for all five generic companies. This is a crucial step towards securing prequalification of the manufacture of these drugs from these companies. WHO prequalification of bioequivalent generic DAAs could then permit their export to eligible countries for mass-treatment programmes. Mass-treatment with low-cost generic HCV DAAs is the most promising method to achieve the ambitious World Health Organization targets for HCV elimination by 2030.

RESUMEN

BACKGROUND: The most recent European Association for the Study of the Liver (EASL) 2016 Guidelines on treatment of hepatitis C (HCV), allowed for shortening the course of treatment for some subsets of patients with sofosbuvir/ledipasvir and with grazoprevir/elbasvir based on cutoff baseline HCV RNA values. We hypothesized that it would be prudent to also consider an objectively assuring very rapid, on-treatment, virologic response to therapy at week 2 (vRVR) before taking the decision of shortening the treatment duration. So we planned this study to test whether a dual sofosbuvir/daclatasvir (SOF/DCV) treatment duration tailored according to achieving vRVR to 8 or 12weeks is non-inferior to the recommended fixed 12weeks course in non-cirrhotic Egyptian chronic HCV genotype-4 patients. METHODS: The study was conducted in an outpatient setting according to a prospective, randomized, open-label, comparative, non-inferiority study design. A hundred twenty eligible, non-cirrhotic, chronic HCV patients were randomly assigned (1:1) to receive daily doses in the form of one Gratisovir 400mg table (generic sofosbuvir produced by Pharco Pharmaceuticals, Alexandria, Egypt) plus one Daktavira 60mg tablet (generic daclatasvir produced by Dawood Pharm, Egypt) for either a fixed 12weeks duration (reference group) or a response tailored duration (test group). In the test group the treatment duration was tailored according to the virus load tested by real time PCR into 8weeks for patients who had undetectable HCV RNA level in their serum by the end of the second week of treatment (vRVR)), or 12weeks for those who did not show vRVR. The primary outcome of the trial was the proportions of patients achieving SVR12 (HCV RNA below lower level of quantification at week 12 after end of treatment). The comparison between groups was based on testing the null hypothesis of inferiority of the response-tailored group with a pre-specified margin of non-inferiority (NI-m) of 0.1 (10%). The protocol was registered with a WHO Clinical Trial Registration ID: ACTRN12617000263392. https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=372041 FINDINGS: Starting from Jun, 5 2016, a hundred twenty eligible patients from 4 outpatient clinics in Alexandria, Egypt were randomized to either a fixed duration group (reference group: n=60 patients) or a response tailored duration group (test group: n=60 patients). During the whole period of the study, only 1 patient dropped-out from each group. Both were lost to follow-up after the 4th week's visit. Baseline characteristics in both groups were almost matching. Fifty eight out of the total 60 intention-to-treat (ITT) patients in the reference group achieved SVR12 (96.67% (95% confidence interval (CI): 88.64-99%). Whereas, 59 out of the total 60 (ITT) patients in the test group achieved SVR12 (98.33% (CI: 91.14-99.71%). The per-protocol (PP) analysis, excluding patients who dropped-out before collecting their final result, showed that 58/59 (98.31% (CI: 91-99.7%)) of patients in the reference group and 59/59 (100% (CI: 93.89-100%) of the test group achieved SVR12. Non-inferiority was declared since the upper bound of the two-sided 95% CI for the difference in proportions of SVR12 between groups (P(reference)-P(test)) did not exceed the specified non-inferiority margin of +0.1 (10%), both in ITT population (-1.67%, CI: -9.8%-+5.9%), and in the PP population (-1.69%, CI: -9%-+4.58%). No fatalities or serious adverse events were reported during the period of the study. Similar rates of non-serious adverse events were reported in both groups with a trend of higher incidence rate in the fixed 12weeks group; all were mild in severity. INTERPRETATION: Shortening the duration of therapy based on observed vRVR could provide a prudent basis to avoid unnecessary long treatment courses. This could not only reduce the drug exposure and the risk of adverse drug reactions, but also cut the cost of full treatment course with such expensive medications by one third. This could economize the treatment budget at the individual out-of-pocket level as well as the public health services and insurance levels and allow for better utilization of public health resources.

RESUMEN

BACKGROUND: This is the second and final report for our study designed to compare two generic sofosbuvir products for the degree and speed of virologic response to a dual anti-hepatitis C virus (HCV) treatment protocol. We aimed to test the applicability of the early virus response kinetics and the very rapid virologic response (vRVR) rate as quick outcome measures for accelerated comparative efficacy studies and as a foundation for a personalized response-guided therapy. METHODS: Fifty eligible chronic HCV patients were randomized to either one of two generic sofosbuvir products (Gratisovir or Grateziano) at a daily dose of one 400 mg tablet plus a weight-based ribavirin dose. Data were compared between the groups for early virus response kinetics and vRVR rates in relation to the rates of final sustained virologic response at week 12 posttreatment (SVR12). RESULTS: The Log10 transformed virus load (Log polymerase chain reaction) curves showed fairly similar rapid decline during the first 2 weeks, with no significant difference between the groups at four analysis points throughout the study by repeated-measures factorial analysis of variance test (P=0.48). The SVR12 rates were 96% (95% confidence interval, 79.6%-99.9%) in Gratisovir group (24/25) and 95.7% (95% confidence interval, 78%-99.9%) in Grateziano group (22/23). There was no statistically significant difference found by exact test (P>0.999). There was a significant association between the vRVR and the SVR12, with 100% positive predictive value (38/38 of those who had vRVR, achieved a final SVR12) and 82.6% sensitivity (among the total 46 with SVR12, 38 were having vRVR). CONCLUSION: We can conclude from our study that the early HCV response kinetics and the vRVR rates could be used as sensitive quick markers for efficacy (with a very high positive predictive value for SVR12), based on our accelerated comparative efficacy research model. This might open the way for new models of accelerated equivalence efficacy studies along with the bioequivalence kinetics studies to test a generic drug against a reference. Also, the early response kinetics and the vRVR might be used as qualifiers for a personalized course of treatment. This could shorten unnecessarily long treatment courses in rapid responders and might help to avoid relapses in slow responders.

RESUMEN

BACKGROUND: Development of an optimal interferon-free regimen for chronic hepatitis C virus infection is believed to require the combination of different drug classes to provide good antiviral efficacy, clinical and quality of life benefits, as well as a high barrier to resistance. Viron(®) is a new herbal drug in film-coated tablet form, and is based on a mixture of herbs with known hepatoprotective and antiviral properties. We conducted this study to explore the safety and the potential clinical and quality of life benefits of this product in patients with chronic hepatitis C infection. METHODS: Eighty-two consecutive patients presenting to our outpatient clinics as already-known or newly-diagnosed cases of chronic hepatitis C virus (HCV) infection, were entered into the study and randomized to three groups to receive escalating doses of Viron for 6 months. Virological, clinical, and enzyme responses, as well as quality of life index scores for chronic liver disease were compared between the groups. RESULTS: Of the 20 patients treated with the highest dose of Viron (three tablets twice daily), two (10%) had a complete virological response at the end of treatment (ETR) and two (10%) had a partial ETR, defined as a decrease in viral load of at least 2-log10 at the end of 6 months of treatment, whereas patients treated with the medium dose (two tablets twice daily) and the lowest dose (one tablet twice daily) showed a significantly lower ETR (P=0.043). Alanine aminotransferase levels and scores on the Chronic Liver Disease Questionnaire improved to a significantly greater extent in the highest dose group (P=0.007 and P=0.021, respectively). No serious adverse effects attributable to the herbal formulation were reported in any of the groups, apart from mild transient nausea, bloating, giddiness, and headache in two patients in the group receiving two tablets twice daily and in three patients in the group receiving three tablets twice daily. CONCLUSION: We conclude that this herbal formulation is potentially safe and may offer some added clinical and quality of life benefits when used in the treatment of patients with chronic hepatitis C virus infection. Larger studies could be warranted to evaluate the effects of using this formulation as an add-on therapy to an all-oral combination of a directly acting antiviral drug protocol in the treatment of chronic hepatitis C.

RESUMEN

BACKGROUND: We aimed in this interim report to compare two registered generic sofosbuvir products for the degree and speed of virologic response to a dual antiviral treatment protocol within the first 2 weeks of treatment. METHODS: Data collected during the period of this interim report from the first 25 patients randomized to either one of two generic sofosbuvir products (Grateziano or Gratisovir) at a daily dose of one 400 mg tablet plus a weight-based ribavirin dose were analyzed for both the degree and speed of virus load reduction at the end of 1 and 2 weeks from starting treatment. RESULTS: The baseline Log10 transformed virus load (Log polymerase chain reaction) showed a fairly similar marked and significant reduction in both groups by more than 4 and 5 Logs at the end of week 1 and 2 of starting treatment, respectively. The differences between the two treatment groups at both analysis points were not statistically significant (P>0.05) by repeated measures factorial analysis of variance test. The differences in proportions of patients with ultra-rapid virologic response at the end of week 1 and very-rapid virologic response at the end of week 2 in both groups were also not statistically significant (P>0.05). CONCLUSION: We can conclude from this interim report that the two generic products Gratisovir and Grateziano are almost equally fast and efficacious in reducing the hepatitis C virus load in our study setting.

RESUMEN

OBJECTIVE: We aimed to investigate the effect of topical application of a Copper indomethacin (Cu-Indo) gel preparation on monosodium iodoacetate (MIA) induced arthritis of the knee joint of rats and to test our hypothesis that copper complex of indomethacin could be a more potent anti-inflammatory agent than its parent compound. METHODS: After induction of osteoarthritis by the intracapsular injection of 50 µL with 40 mg/mL MIA, we compared the anti-inflammatory efficacy and safety of a topical application of 1% indomethacin gel in a dose of 1 g/kg of the gel (equivalent to 10 mg/kg of the active substance) daily for 3 weeks versus three decremental dose levels of Cu-Indo gel: an equivalent dose, half the dose, and 25% of the dose of indomethacin. Anti-inflammatory efficacy was assessed in all treated groups by measurement of serum inflammatory cytokines: interleukin 6, interleukin 8, and tumor necrosis factor alpha; and by the weekly assessment of knee joint swelling. Joint mobility and motor coordination were also assessed once weekly by the accelerating rotarod apparatus; histopathological examination of affected joints was also performed. Safety of topical application of Cu-Indo (0.25, 0.5, and 1 g/kg) for up to 3 months to rats' skin was determined by the estimation of a complete blood count, liver and kidney functions, and histopathologic examination for target tissues. RESULTS: Cu-Indo gel at lower doses was superior to or at least as effective as its parent substance, indomethacin, in most of the studied parameters of inflammation. The lowest tested dose of Cu-Indo, corresponding to 25% of the parent substance indomethacin, exhibited the highest efficacy in reducing the elevated serum-tested interleukins and in increasing the time of duration on the rotarod test, whereas its effect on reduction of edema and tumor necrosis factor alpha was comparable to that of the others. After 3 months of daily application, there were no notable changes in studied safety parameters with the lowest Cu-Indo dose, but the group treated with the higher dose showed a small but statistically significant increase in serum-unconjugated bilirubin and a slight decrease in hemoglobin levels, red blood cells, and platelet count, with normal indices denoting a slight hemolytic effect at the highest dose. CONCLUSION: Cu-Indo gel has potent anti-inflammatory activity against joint inflammation in the MIA-treated rat model of osteoarthritis at doses of 0.25, 0.5, and 1 g/kg. The lowest studied dose was better on both safety and efficacy parameters.

RESUMEN

BACKGROUND: Renal colic is typically characterized by the sudden onset of severe pain radiating from the flank to the groin and its acute management in emergency departments essentially aims at rapid pain relief. Spasmofen(®) is a brand of Amriya Pharmaceutical Industries in the form of rectal suppositories containing ketoprofen 100 mg and hyoscine butylbromide 10 mg. This combination is intended for the rapid relief of severe colicky pain in the renal system, hepatobiliary system, or gastrointestinal tract. This trial aims to compare a single-dose of Spasmofen rectal suppository to a single intravenous (IV) ketorolac tromethamine 30 mg/2 mL dose in patients with acute renal colic. METHODS: A total of 80 eligible consecutive patients presenting to the emergency departments of two medical centers with acute renal colic were included in the study. Eligible patients who signed the informed consent were randomly assigned into two treatment groups: an experimental group (Spasmofen group) who received one Spasmofen rectal suppository plus an IV injection of 2 mL of normal saline solution; and a control group (ketorolac group) who received one ketorolac 30 mg/2 mL ampoule IV plus one placebo suppository. Treatment success, defined as a change in the verbal rating score from severe or moderate pain to none or mild at 60 minutes after the dose, was compared between groups using the chi-square/Fisher's exact test. Percentage reductions in visual pain analog scale (VPAS) scores at 15 and 60 minutes after the dose were compared between groups using the Z-test for proportions. RESULTS: Successful treatment at 60 minutes occurred in 35 of 40 (87.5%) of Spasmofen-treated patients and in 33 of 40 (82.5%) of ketorolac-treated patients. The difference was not statistically significant by Fisher's exact test (P=0.755). The mean percentage reduction of VPAS after 15 minutes was 61.82% in the Spasmofen-treated group and 64.76% in the ketorolac-treated group. The difference was also not statistically significant by the Z-test for proportions (P=0.795). Sixty minutes after being treated, Spasmofen was associated with a statistically significant greater reduction in VPAS (mean% reduction =92.36%) than ketorolac (75.06%; P=0.0466). CONCLUSION: Single-dose Spasmofen rectal suppository might be a safe and effective first-aid treatment for the emergency department relief of acute renal colic.

RESUMEN

BACKGROUND: Mild cognitive impairment encompasses the clinical continuum between physiologic age-related cognitive changes and dementia. A variety of medications, including herbal preparations (in particular Ginkgo biloba and Panax ginseng), have been advocated as treatments for cognitive impairment in the elderly. In this study, we investigated the effect of an already marketed dietary supplement (Memo®) combining 750 mg of lyophilized royal jelly with standardized extracts of G. biloba 120 mg and P. ginseng 150 mg on Mini-Mental State Examination (MMSE) scores in patients with mild cognitive impairment. METHODS: Sixty-six subjects presenting with forgetfulness and satisfying the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) clinical criteria for mild cognitive impairment were randomly divided into an experimental group treated with one Memo capsule before breakfast daily for 4 weeks and a control group who took placebo. The mean change in MMSE score from baseline and reported adverse effects were compared between the two groups. RESULTS: The mean change in MMSE score in the group treated with Memo for 4 weeks was significantly greater than in the control group (+2.07 versus +0.13, respectively) by the Student's t-test (t = 6.485, P < 0.0001). This was also true after adjusting for age as a covariate and educational level as a factor nested within the treatment groups in a general linear model (analysis of covariance, F = 9.675 [corrected model], P < 0.0001). CONCLUSION: This combined triple formula may be beneficial in treating the cognitive decline that occurs during the aging process as well as in the early phases of pathologic cognitive impairment typical of insidious-onset vascular dementia and in the early stages of Alzheimer's disease. Larger-sized studies with longer treatment durations are needed to confirm this.

RESUMEN

BACKGROUND: Lactuca sativa (garden lettuce) is a popular salad herb. It has been in use in folk medicine since ancient times as both an appetite stimulant and as an aid to sleep. L. sativa seed oil (Sedan(®)) has demonstrated a pronounced sedative effect and potentiated the hypnotic effect of barbiturates in animal models. It also exhibited significant analgesic and anti-inflammatory activities. In this study, we evaluated the sedative and hypnotic effects of L. sativa in patients suffering from insomnia. METHODS: Sixty patients suffering from insomnia with or without anxiety were randomized to receive capsules containing L. sativa seed oil 1000 mg (n = 30) or placebo (n = 30). All patients were asked to complete a verbal questionnaire before the start of the trial and 1 week after starting treatment. RESULTS: Improvements in the modified State-Trait Anxiety Inventory and the Sleep rating scale scores were significantly greater in patients receiving L. sativa seed oil compared with those on placebo (P < 0.05). No side effects were found to be attributable to L. sativa seed oil at the given dosage. CONCLUSION: L. sativa seed oil was found to be a useful sleeping aid and may be a hazard-free line of treatment, especially in geriatric patients suffering from mild-to-moderate forms of anxiety and sleeping difficulties.
