There are about 2216 clinical studies being (or have been) conducted in Thailand. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Historically, Plasmodium vivax has been termed "benign" due to its non-life threatening clinical course and since the 1800's this view has been cultivated as demonstrated by the use of the term "benign tertian malaria" to describe the infection.1 However over the last 15 years, more severe P. vivax malaria is being reported, causing concern that severe P. vivax malaria is under diagnosed.1,2 The definition of severe P. vivax malaria borrows from P. falciparum and is primarily one of exclusion. Species PCR (polymerase chain reaction) is the only way to prove P. vivax mono-infection but is expensive and requires skilled staff and technology. In resource constrained settings, diagnostic testing is not available for detection of most non-malarial infections further affecting the ability to determine whether severe symptoms are due to P. vivax malarial infection or a concomitant one. Retrospective studies from India, Pakistan, Indonesia, Papua New Guinea and Sudan support the existence of severe P. vivax malaria.3-13 However, inconsistent methodologies, definitions of severity, and use of diagnostic tests to exclude concomitant infection do not allow for standardised assessments for severe P. vivax infection across studies. A review by Baird, highlighted that the risk of being classed as suffering from severe illness was only minimally higher in P. falciparum than in P. vivax, but was unable to combine the data as a meta-analysis.1 The primary reported symptoms for severe P. vivax included severe anaemia particularly in children, severe thrombocytopaenia, respiratory distress, neurological syndromes (coma or seizures), renal and hepatic failure. Prospective studies have shown similar results. Tjitra et al showed that 23% (675 of 2,937) patients admitted with microscopically diagnosed P. vivax infections in Papua, Indonesia had severe disease and that the risk of severe malaria was significantly higher when admitted with P. vivax than with P. falciparum.14 In studies from Papua New Guinea, few differences between the clinical presentation of P. falciparum and P. vivax were found in children with severe malaria.15,16 This appears to be similar in populations from Sudan, Pakistan and India.13,17-23 In contrast, in Thailand, anecdotal observations note a low prevalence of severe P. vivax infections. The WHO criteria to assess severe P. falciparum have been extrapolated to P. vivax. In the 2015 WHO malaria guidelines some criteria now account for P. vivax, such as removing a minimum parasitaemia when assessing for severe anaemia.24 Whilst these criteria may not be the most sensitive tool to define severe P. vivax infections, it is used for this purpose. It has been suggested that additional clinical information may be necessary to define truly severe P. vivax cases.25 In order to describe the characteristics of the severity of P. vivax infections in north-western Thailand, we will perform a retrospective review of annual reports of the outpatient database, the inpatient database and eligible inpatient medical records from 2001 to 2016. The WHO malaria guidelines and additional clinical information will be used to assess the severity of infection and thus, a rate of severe P. vivax can be determined.
The purpose of this study is to determine the efficacy of pembrolizumab given in combination with either ipilimumab or placebo as first-line treatment in participants with metastatic non-small cell lung cancer (NSCLC). The primary hypothesis of this study is that overall survival (OS) and/or progression-free survival (PFS) is prolonged in participants who receive pembrolizumab and ipilimumab compared to those who receive pembrolizumab and placebo.
This Phase 3 study is intended to assess the efficacy of the Quadrivalent VLP Influenza Vaccine during the 2017-2018 influenza season in healthy adults 18 to 64 years of age. One dose of Quadrivalent Virus-Like Particles (VLP) Influenza Vaccine (30 μg/strain) or of placebo will be administered to approximately 10,000 subjects.
This is a randomized, open-label, multi-center, global, Phase III study to assess the efficacy and safety of durvalumab plus tremelimumab combination therapy and durvalumab monotherapy versus sorafenib in the treatment of patients with no prior systemic therapy for unresectable HCC. The patients cannot be eligible for locoregional therapy.
Inhalants, which are neurotoxic central nervous system (CNS) suppressants, are frequently abused by young adults. Unlike other CNS depressants, including alcohol and opiates, no treatment is currently approved for inhalants dependence. In this report, a novel approach of substitution treatment for inhalants addiction was explored in a double-blinded, randomized, controlled crossover design to examine the effects of inhalation of essential oil (EO) and perfume (PF) on the reduction of cue-induced craving for inhalants in a cohort of thirty-four Thai males with inhalants dependence. The craving response was measured by the modified version of Penn Alcohol Craving Score for Inhalants (PACS-inhalants)
This is a multicenter, multinational, double-blind, 1:1 randomized, parallel-group, equivalence Phase 3 study to compare the efficacy and safety of MB02 plus chemotherapy (carboplatin and paclitaxel) versus Avastin® plus chemotherapy (carboplatin and paclitaxel) in subjects with Stage IIIB/IV non-squamous NSCLC
High-efficiency post-dilution online hemodiafiltration (OL-HDF) using high-flux dialyzer and requiring high blood flow rate (BF ≥400 mL/min) has been reported to enhance protein-bound toxin and middle molecular toxin removal and improve patient survival. Unfortunately, the majority of patients could not reach that high BF because of vascular access issue. This randomized crossover study was conducted to compare these uremic toxin removals between the new modality (limited BF OL-HDF with super high-flux dialyzer) and the control (high-efficiency OL-HDF). The OL-HDF patients were randomized to undergo either new modality or control for 2 weeks before crossover to the other modality for another 2 weeks.
The purpose of this pilot study is to examine a 12-week self-management energy conservation program (ECAM)'s effects on fatigue, and secondarily on sleep, physical activity, anxiety and depression, self-efficacy, and beliefs about fatigue in a group of Thai women with breast cancer who are undergoing chemotherapy. We will also evaluate how well women like the intervention, how easy it is to use and whether women will do the activities.
Postoperative pain after thoracic surgery is associated with adverse outcomes. The current strategy to prevent postoperative pain is the use of regional anesthesia and analgesic agents. In video-assisted thoracic surgery (VATS), thoracic paravertebral block has become the standard analgesic regimen which results in decreased postoperative pain and opioid consumption. The investigator would like to study the analgesic efficacy of low dose intravenous ketamine infusion during surgery in combination with thoracic paravertebral block on postoperative pain after VATS in a randomized study.
The high chloride content of 0.9%sodium chloride (0.9%NaCl) leads to adverse pathophysiological effects in both animals and healthy human volunteers. Small randomized trials confirm that the hyperchloremic acidosis induced by 0.9%NaCl also occurs in patients. A strong signal is emerging from recent large propensity-matched and cohort studies for the adverse effects that 0.9% NaCl has on the clinical outcome in surgical and critically ill patients when compared with balanced crystalloids. Major complications are the increased incidences of acute kidney injury and the need for renal replacement therapy, and that pathological hyperchloremia may increase postoperative mortality. Fluid resuscitation with 0.9% NaCl in animals with sepsis resulted in hyperchloremic metabolic acidosis, worsened AKI, and increased mortality when compared with resuscitation with a balanced crystalloid solution. Furthermore, hyperchloremic acidosis also resulted in increased concentrations of circulating inflammatory mediators in an experimental model of severe sepsis in rats, with a dose-dependent increase in circulating interleukin-6, tumor necrosis factor-a, and interleukin-10 concentrations with increasing acidosis. Thus, in this study, investigators compared the effects of a balanced crystalloid solution with 0.9% NaCl on the renal function in severe sepsis/septic shock patients. Investigators hypothesized that balanced crystalloid solution resuscitation would decrease AKI incidence and severity and would improve immunomodulatory effect when compared with 0.9% NaCl resuscitation.
