RESUMEN

Objective: To compare cervical ripening time with the use of vaginal Misoprostol plus Hyoscine-N-Butylbromide, with vaginal Misoprostol alone. Design: A double-blind randomized controlled trial with Pan-African Clinical Trials Registry (PACTR) approval number PACTR202112821475292. Setting: Federal Medical Centre, Asaba, Nigeria. Participants: A total of 126 eligible antenatal patients for cervical ripening were enrolled. Interventions: Participants in Group A had 25µg of vaginal misoprostol with 1ml of intramuscular placebo, and those in Group B had 25µg of vaginal misoprostol with 20mg of Intramuscular Hyoscine (1 ml). Oxytocin infusion was used when indicated, and the labour was supervised as per departmental protocol. Main outcome measure: Cervical ripening time. Results: The mean cervical ripening time was statistically significantly shorter in the hyoscine group (8.48±4.36 hours) than in the placebo group (11.40±7.33 hours); p-value 0.02, 95% CI 0.80-5.05. There was no statistically significant difference in the mean induction-delivery interval in Group A (7.38±5.28 hours) compared to Group B (7.75±5.04 hours), with a value of 0.54. The mode of delivery was comparable. However, women in Group B (53, 84.1%) achieved more vaginal deliveries than women in Group A (50, 79.4%); p-value 0.49. Thirteen women in Group A (20.6%) had a caesarean section, while ten women (15.9%) in Group B had a caesarean section (p-value 0.49, RR 0.94, CI 0.80-1.11). Adverse maternal and neonatal outcomes were not statistically significant between the two groups. Conclusion: Intramuscular hyoscine was effective in reducing cervical ripening time when used as an adjunct to vaginal Misoprostol, with no significant adverse maternal or neonatal outcome. Funding: None declared.

RESUMEN

BACKGROUND AND OBJECTIVES: There were 82.4 million new gonorrhoea cases worldwide in 2020. Dual treatment with ceftriaxone or cefixime and azithromycin or doxycycline is currently recommended for gonorrhoea in Indonesia. However, reduced susceptibility and resistance to cephalosporins and azithromycin are increasing. We evaluated the susceptibility pattern of Neisseria gonorrhoeae to cefixime, ceftriaxone, azithromycin and doxycycline. METHOD: N. gonorrhoeae isolates were obtained from 19 male participants with clinically and laboratory-confirmed gonorrhoea. Antibiotic susceptibility testing was conducted by disc diffusion and interpreted according to Clinical and Laboratory Standards Institute and Centers for Disease Control and Prevention criteria. RESULTS: Reduced susceptibility or resistance was observed against doxycycline in 19 isolates (100%), cefixime in six (31.6%), ceftriaxone in three (15.8%) and azithromycin in zero (0%) isolates. DISCUSSION: A dual treatment regimen with ceftriaxone and azithromycin can still be recommended as first-line therapy for gonorrhoea in Indonesia. Antibiotic susceptibility surveillance of N. gonorrhoeae should be routinely conducted.

RESUMEN

INTRODUCTION: Gastric ulcer is one of the most common and serious conditions in the gastrointestinal tract. One of the main causes of gastric ulcers is using of non-steroidal anti-inflammatory drugs (NSAIDs) which have limited their use in clinical practice. Several studies have revealed that metformin and Vitamin C (Vit C) exhibit protective effects against gastric mucosal damage in different animal models. However, no studies indicate their combination's effect on gastric ulcer models. Therefore, this study aims to investigate the protective effects of metformin and Vit C combination on indomethacin-induced gastric ulcers. MATERIAL AND METHODS: In total, thirty rats were divided into six groups, including the control group, rats received indomethacin (50 mg/kg, i.p.), rats received indomethacin and pretreated with ranitidine (100 mg/kg), metformin (100 mg/kg, i.p.), Vit C (100 mg/kg), or metformin combined with Vit C. Four hours after indomethacin administration, rats were euthanized, and gastric tissues were removed for macroscopic, histopathologic, and biochemical examinations. RESULTS: All therapeutics used in this study were found to alleviate gastric mucosal injury caused by indomethacin, as observed in histopathologic and macroscopic evaluations. Both Vit C and metformin were observed to significantly decrease lipid peroxidation and enhance the activity of anti-oxidative enzymes, SOD, GPx, and catalase. However, a more significant effectiveness was observed in catalase and GPx activities when Vit C was co-administered with metformin. CONCLUSIONS: In conclusion, the present study revealed that metformin and Vit C combination therapy could potentially treat gastric ulcers associated with indomethacin.

RESUMEN

BACKGROUND: Medication non-adherence is a significant problem in patients with Chronic Obstructive Pulmonary Disease (COPD). Efforts to address this issue are receiving increased attention. Simplifying treatment by prescribing single-inhaler triple therapy (SITT) as an alternative to multi-inhaler triple therapy (MITT) or with smart inhalers are often considered potential solutions. However, the actual impact of these innovations on adherence and clinical outcomes is unclear. METHODS: To address this knowledge gap we first conducted a literature review focusing on two research questions: 1) the difference in adherence between SITT and MITT users in COPD, and 2) the effect of smart inhalers on adherence in COPD. Separate searches were conducted in PubMed and two authors independently assessed the articles. In addition, we present a protocol for a study to acquire knowledge for the gaps identified. RESULTS: To address the first research question, 8 trials were selected for further review. All trials were observational, i.e. randomized controlled trials were lacking. Seven of these trials showed higher adherence and/or persistence in patients on SITT compared with patients on MITT. In addition, four studies showed a positive effect of SITT on various clinical outcomes. For the second research question, 11 trials were selected for review. While most of the studies showed a positive effect of smart inhalers on adherence, there was considerable variation in the results regarding their effect on other clinical outcomes. The TRICOLON (TRIple therapy COnvenience by the use of one or multipLe Inhalers and digital support in ChrONic Obstructive Pulmonary Disease) trial aims to improve understanding regarding the effectiveness of SITT and smart inhalers in enhancing adherence. This open-label, randomized, multi-center study will enroll COPD patients requiring triple therapy at ten participating hospitals. In total, 300 patients will be randomized into three groups: 1) MITT; 2) SITT; 3) SITT with digital support through a smart inhaler and an e-health platform. The follow-up period will be one year, during which three methods of measuring adherence will be used: smart inhaler data, self-reported data using the Test of Adherence to Inhalers (TAI) questionnaire, and drug analysis in scalp hair samples. Finally, differences in clinical outcomes between the study groups will be compared. DISCUSSION: Our review suggests promising results concerning the effect of SITT, as opposed to MITT, and smart inhalers on adherence. However, the quality of evidence is limited due to the absence of randomized controlled trials and/or the short duration of follow-up in many studies. Moreover, its impact on clinical outcomes shows considerable variation. The TRICOLON trial aims to provide solid data on these frequently mentioned solutions to non-adherence in COPD. Collecting data in a well-designed randomized controlled trial is challenging, but the design of this trial addresses both the usefulness of SITT and smart inhalers while ensuring minimal interference in participants' daily lives. TRIAL REGISTRATION: NCT05495698 (Clinicaltrials.gov), registered at 08-08-2022. Protocol version: version 5, date 27-02-2023.

RESUMEN

Antiretroviral regimens for human immunodeficiency virus (HIV) infection have continuously evolved; however, antiretrovirals can cause severe adverse reactions. Two-drug regimen therapy can decrease lifetime cumulative drug exposure and long-term toxicities associated with multiple antiretrovirals. The preferred 2-drug regimen constitutes dolutegravir (DTG) and lamivudine (3TC). This study determined the rate of virological suppression and incidence of adverse events at week 48 in treatment-naïve people living with HIV initiated on DTG + 3TC. This was a single-center, retrospective, observational study. Treatment-naïve people aged ≥18 years who received at least 1 DTG + 3TC dose between May 2020 and May 2022 were included. Eighty-nine people living with HIV were enrolled. Twenty-five (28.1%) patients with a DTG + 3TC regimen at baseline were analyzed because of comorbidities, and 48% because of concomitant tuberculosis (TB). Viral suppression at 48 weeks was achieved in 91.67% of patients, and TB was well controlled. At week 48, 84 (94.38%) patients had viral loads < 50 copies/mL, and 21 (91.31%) of the 23 participants with a baseline HIV-1-RNA level ≥ 1 × 105 copies/mL achieved virological success. Fifteen (88.23%) of the 17 participants with a baseline CD4 + cell count of <200 cells/µL achieved virological suppression. The median CD4 + cell count change from baseline was 539.5 cells/µL. No significant changes in triglycerides, low-density lipoprotein cholesterol, weight, or creatinine were observed from baseline to 48 weeks. One patient had severe insomnia at 4 weeks. Our findings support the real-world effectiveness and low metabolic impact of DTG + 3TC. Using DTG + 3TC in patients coinfected with TB and HIV has favorable therapeutic outcomes.

RESUMEN

There is an increasing need for new treatment regimens to combat antibiotic-resistant strains of bacteria. Staphylococcus aureus is a clinically important, opportunist pathogen that has developed resistance to a range of antibiotics. The zebrafish larval model of systemic disease has been increasingly utilized to elucidate S. aureus virulence mechanisms and host-pathogen interactions. Here, we outline how this model can be used to investigate the effects of different antibiotics alone and in combination against S. aureus.

RESUMEN

Current clinical practice assumes that a single antibiotic given as a bolus or as a course will successfully treat most infections. In modern medicine, this is becoming less and less true with drug-resistant, multi-drug-resistant, extensively drug-resistant, and untreatable infections becoming more common. Where single-drug therapy (monotherapy) fails, we will turn to multi-drug therapy. Alternatively, combination therapy could be useful to prevent the emergence of resistance. Multi-drug therapy is already standard for some multi-drug resistant infections and is the standard for the treatment of some pathogens such as Mycobacterium tuberculosis.The use of combination therapy for everyday infections could be a clear course out of the current AMR crisis we are facing. With every additional drug added to a combination (n + 1) the likelihood of the pathogen evolving resistance drops exponentially.Many generic antibiotics are cheap to manufacture as they have fallen out of patent protection but are less effective at pharmacologically effective doses due to overuse in the past. Combination therapy can combine these generic compounds into cocktails that can not only treat susceptible and resistant infections but can also reduce the risk of new resistances arising and can resuscitate the use of antimicrobials once thought defunct.In this chapter, we will summarize theory behind combination therapy and standard in vitro methodologies used.

RESUMEN

BACKGROUND: Eradicating Helicobacter pylori infection by bismuth quadruple therapy (BQT) is effective. However, the effect of BQT and subsequent fecal microbiota transplant (FMT) on the gut microbiota is less known. MATERIALS AND METHODS: This prospective randomized controlled trial was conducted at a tertiary hospital in China from January 2019 to October 2020, with the primary endpoints the effect of BQT on the gut microbiota and the effect of FMT on the gut microbiota after bismuth quadruple therapy eradication therapy. A 14-day BQT with amoxicillin and clarithromycin was administered to H. pylori-positive subjects, and after eradication therapy, patients received a one-time FMT or placebo treatment. We then collected stool samples to assess the effects of 14-day BQT and FMT on the gut microbiota. 16 s rDNA and metagenomic sequencing were used to analyze the structure and function of intestinal flora. We also used Gastrointestinal Symptom Rating Scale (GSRS) to evaluate gastrointestinal symptom during treatment. RESULTS: A total of 30 patients were recruited and 15 were assigned to either FMT or placebo groups. After eradication therapy, alpha-diversity was decreased in both groups. At the phylum level, the abundance of Bacteroidetes and Firmicutes decreased, while Proteobacteria increased. At the genus level, the abundance of beneficial bacteria decreased, while pathogenic bacteria increased. Eradication therapy reduced some resistance genes abundance while increased the resistance genes abundance linked to Escherichia coli. While they all returned to baseline by Week 10. Besides, the difference was observed in Week 10 by the diarrhea score between two groups. Compared to Week 2, the GSRS total score and diarrhea score decreased in Week 3 only in FMT group. CONCLUSIONS: The balance of intestinal flora in patients can be considerably impacted by BQT in the short term, but it has reverted back to baseline by Week 10. FMT can alleviate gastrointestinal symptoms even if there was no evidence it promoted restoration of intestinal flora.

RESUMEN

PURPOSE: We aim to explore a potential treatment strategy for hair loss. MATERIALS AND METHODS: A male 6-year-old child was diagnosed with hidrotic ectodermal dysplasia 2 (HED2) caused by GJB6 (p.G11R) mutations. He presented at our clinic with diffuse thinning and fine and brittle hair since birth. Additionally, the child exhibited abnormal development of teeth, fingernails, and toenails. The condition of the child's hair had not improved significantly with age. He was treated with botanical extracts combined with Minoxidil. RESULTS: After one and a half months of treatment, the patient showed remarkable hair growth. CONCLUSIONS: Our team has previously used botanical extracts in combination for the treatment of autosomal recessive wooly hair in children. In the present case, treatment with botanical extract combined with minoxidil was found to be equally efficacious. This case report provides valuable information for future studies on the use of botanical extracts in treating hair loss, as well as a safe and effective potential treatment strategy for children with congenital alopecia.

RESUMEN

BACKGROUND: Single-pill combination (SPC) of three antihypertensive drugs has been shown to improve adherence to therapy compared with free combinations, but little is known about its long-term costs and health consequences. This study aimed to evaluate the lifetime cost-effectiveness profile of a three-drug SPC of an angiotensin-converting enzyme inhibitor, a calcium-channel blocker, and a diuretic vs the corresponding two-pill administration (a two-drug SPC plus a third drug separately) from the Italian payer perspective. METHODS: A cost-effectiveness analysis was conducted using multi-state semi-Markov modeling and microsimulation. Using the healthcare utilization database of the Lombardy Region (Italy), 30,172 and 65,817 patients aged ≥ 40 years who initiated SPC and two-pill combination, respectively, between 2015 and 2018 were identified. The observation period extended from the date of the first drug dispensation until death, emigration, or December 31, 2019. Disease and cost models were parametrized using the study cohort, and a lifetime microsimulation was applied to project costs and life expectancy for the compared strategies, assigning each of them to each cohort member. Costs and life-years gained were discounted by 3%. Probabilistic sensitivity analysis with 1,000 samples was performed to address parameter uncertainty. RESULTS: Compared with the two-pill combination, the SPC increased life expectancy by 0.86 years (95% confidence interval [CI] 0.61-1.14), with a mean cost differential of -€12 (95% CI -9,719-8,131), making it the dominant strategy (ICER = -14, 95% CI -€15,871-€7,113). The cost reduction associated with the SPC was primarily driven by savings in hospitalization costs, amounting to €1,850 (95% CI 17-7,813) and €2,027 (95% CI 19-8,603) for patients treated with the SPC and two-pill combination, respectively. Conversely, drug costs were higher for the SPC (€3,848, 95% CI 574-10,640 vs. €3,710, 95% CI 263-11,955). The cost-effectiveness profile did not significantly change according to age, sex, and clinical status. CONCLUSIONS: The SPC was projected to be cost-effective compared with the two-pill combination at almost all reasonable willingness-to-pay thresholds. As it is currently prescribed to only a few patients, the widespread use of this strategy could result in benefits for both patients and the healthcare system.

RESUMEN

BACKGROUND: Plasmodium vivax malaria is still an important public health problem in Ethiopia. Unlike Plasmodium falciparum, P. vivax has a dormant liver stage (hypnozoite) that can be a risk of recurrent vivax malaria unless treated by radical cure with primaquine. Drug resistance to chloroquine is threatening malaria control and elimination efforts. This study assessed the therapeutic efficacy and safety of chloroquine plus 14 days of primaquine on P. vivax infection based on parasitological, clinical, and haematological parameters. METHODS: A single-arm in vivo prospective therapeutic efficacy study was conducted to assess the clinical and parasitological response to the first-line treatment of P. vivax in Ethiopia, chloroquine plus 14 days low dose of (0.25 mg/kg/day) primaquine between December 2022 and March 2023 at Hamusit Health Centre using the standard World Health Organization (WHO) protocol. A total of 100 study participants with P. vivax mono-infection who were over 6 months old were enrolled and monitored for adequate clinical and parasitological responses for 42 days. The WHO double-entry Excel sheet and SPSS v.25 software were used for Kaplan-Meier survival analysis, and a paired t-test was used for analysis of haemoglobin improvements between follow up days. RESULTS: A total of 100 patients were enrolled among those, 96% cases were rural residents, 93% had previous malaria exposure, and predominant age group was 5-15 years (61%). 92.6% (95% CI 85.1-96.4%) of enrolled patients were adequate clinical and parasitological response, and 7.4% (95% CI 3.6-14.9%) recurrences were observed among treated patients. The fever and parasite clearance rate on day 3 were 98% and 94%, respectively. The baseline haemoglobin levels improved significantly compared to those days 14 and 42 (p < 0.001). No serious adverse event was observed during the study period. CONCLUSIONS: In this study, co-administration of chloroquine with primaquine was efficacious and well-tolerated with fast resolution of fever and high parasites clearance rate. However, the 7.4% failure is reported is alarming that warrant further monitoring of the therapeutic efficacy study of P. vivax.

RESUMEN

BACKGROUND: Glaucoma treatment often involves multi-drug regimens, which can lead to poor adherence and side effects. Fixed-dose combinations aim to improve adherence and reduce side effects compared to traditional therapies. This study aimed to compare the prevalence and clinical characteristics of ocular allergy in glaucoma patients using brinzolamide 1.0%/brimonidine 0.2% fixed combination (BBFC), with and without concurrent ß-blocker. METHODS: Of these, 176 patients used a ß-blocker concurrently, whereas 96 patients did not. Allergy prevalence, allergy type, and allergy occurrence time were compared between the concurrent and non-concurrent ß-blocker-usage groups. Ocular allergies were classified and evaluated using Kaplan-Meier survival analysis. RESULTS: Allergy prevalence was 10.23% and 15.63% (p = 0.193), whereas allergy occurrence time was 15.92 ± 13.80 months and 6.26 ± 6.20 months (p = 0.04) in the concurrent and non-concurrent ß-blocker-usage groups, respectively. Kaplan-Meier survival analysis indicated that half of the allergies in the concurrent ß-blocker-usage group occurred within 12.5 months, with the BBFC discontinuation rate gradually increasing up to 36 months. Contrarily, half of the allergies in the non-concurrent ß-blocker-usage group occurred within 3.3 months, with a rapid increase in BBFC discontinuation rate the first 6 months. Intergroup differences in allergy types were significant (p = 0.015). Among all patients with allergy, the average allergy occurrence time of blepharoconjunctivitis, papillary conjunctivitis, and follicular conjunctivitis was 12.52, 9.53, and 13.23 months, respectively. Follicular conjunctivitis tended to occur later than papillary conjunctivitis (p = 0.042). In the concurrent ß-blocker-usage group, follicular conjunctivitis was the most prevalent allergy type (61.1%), whereas papillary conjunctivitis was the most common (66.7%) in in the non-concurrent ß-blocker-usage group. CONCLUSIONS: Concurrent use of ß-blocker with BBFC decreases allergy prevalence, delays allergy onset, and predominantly results in follicular conjunctivitis, thereby facilitating longer treatment duration. Understanding these characteristics of allergy in BBFC users is useful to manage patients and improve treatment adherence. This study provides insights into the role of ß-blockers in modulating ocular allergy in BBFC-treated glaucoma patients, highlighting implications for clinical practice and patient education.

Five hundred thirty-seven million people globally suffer from diabetes. Insulin-producing ß cells are reduced in number in most people with diabetes, but most individuals still have some residual ß cells. However, none of the many diabetes drugs in common use increases human ß cell numbers. Recently, small molecules that inhibit dual tyrosine-regulated kinase 1A (DYRK1A) have been shown to induce immunohistochemical markers of human ß cell replication, and this is enhanced by drugs that stimulate the glucagon-like peptide 1 (GLP1) receptor (GLP1R) on ß cells. However, it remains to be demonstrated whether these immunohistochemical findings translate into an actual increase in human ß cell numbers in vivo. It is also unknown whether DYRK1A inhibitors together with GLP1R agonists (GLP1RAs) affect human ß cell survival. Here, using an optimized immunolabeling-enabled three-dimensional imaging of solvent-cleared organs (iDISCO+) protocol in mouse kidneys bearing human islet grafts, we demonstrate that combination of a DYRK1A inhibitor with exendin-4 increases actual human ß cell mass in vivo by a mean of four- to sevenfold in diabetic and nondiabetic mice over 3 months and reverses diabetes, without alteration in human α cell mass. The augmentation in human ß cell mass occurred through mechanisms that included enhanced human ß cell proliferation, function, and survival. The increase in human ß cell survival was mediated, in part, by the islet prohormone VGF. Together, these findings demonstrate the therapeutic potential and favorable preclinical safety profile of the DYRK1A inhibitor-GLP1RA combination for diabetes treatment.

RESUMEN

Hyperinflammatory Coronavirus disease 2019 (COVID-19) and rapidly-progressive interstitial lung diseases (RP-ILD) secondary to inflammatory myopathies (IIM) present important similarities. These data support the use of anti-rheumatic drugs for the treatment of COVID-19. The aim of this study was to compare the efficacy of combining baricitinib and pulse steroids with the Standard of Care (SoC) for the treatment of critically ill COVID-19 patients. We retrospectively enrolled consecutive patients admitted to the Intensive Care Unit (ICU) with COVID-19-pneumonia. Patients treated with SoC (dexamethasone plus remdesivir) were compared to patients treated with baricitinib plus 6-methylprednisolone pulses (Rheuma-group). We enrolled 246 patients: 104/246 in the SoC and 142/246 in the Rheuma-group. All patients presented laboratory findings suggestive of hyperinflammatory response. Sixty-four patients (26.1%) died during ICU hospitalization. The mortality rate in the Rheuma-group was significantly lower than in the SoC-group (15.5 vs. 40.4%, p < 0.001). Compared to the SoC-group, patients in the Rheuma-group presented significantly lower inflammatory biomarker levels after one week of treatment. Higher ferritin levels after one week of treatment were strongly associated with mortality (p < 0.001). In this large real-life COVID-19 cohort, baricitinib and pulse steroids led to a significant reduction in mortality, paralleled by a prompt reduction in inflammatory biomarkers. Our experience supports the similarities between hyperinflammatory COVID-19 and the IIM-associated RP-ILD.

RESUMEN

Introduction: Cholesteryl ester transfer protein (CETP) inhibitors, initially developed for treating hyperlipidemia, have shown promise in reducing the risk of new-onset diabetes during clinical trials. This positions CETP inhibitors as potential candidates for repurposing in metabolic disease treatment. Given their oral administration, they could complement existing oral medications like sodium-glucose cotransporter 2 (SGLT2) inhibitors, potentially delaying the need for injectable therapies such as insulin. Methods: We conducted a 2x2 factorial Mendelian Randomization analysis involving 233,765 participants from the UK Biobank. This study aimed to evaluate whether simultaneous genetic inhibition of CETP and SGLT2 enhances glycemic control compared to inhibiting each separately. Results: Our findings indicate that dual genetic inhibition of CETP and SGLT2 significantly reduces glycated hemoglobin levels compared to controls and single-agent inhibition. Additionally, the combined inhibition is linked to a lower incidence of diabetes compared to both the control group and SGLT2 inhibition alone. Discussion: These results suggest that combining CETP and SGLT2 inhibitor therapies may offer superior glycemic control over SGLT2 inhibitors alone. Future clinical trials should investigate the potential of repurposing CETP inhibitors for metabolic disease treatment, providing an oral therapeutic option that could benefit high-risk patients before they require injectable therapies like insulin or glucagon-like peptide-1 (GLP-1) receptor agonists.
