There are about 3709 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.
Logotherapy has never been evaluated in HIV-infected teenagers. In this study, we will evaluate the meaning of life by using The Purpose in Life Test and the affect of logotherapy in HIV infected youth at HIV-NAT, Thai Red Cross AIDS Research Centre and King Chulalongkorn Memorial Hospital.
To explore allergen-specific effector and regulatory T cell response in HIV-infected children before and after HAART initiation
Tranexamic acid has benn widely used to reduce perioperative bleeding in several operations such as cardiac surgery, liver transplant and joint arthroplasty with good results. Few studies in laminectomy had conflicting results and varying in doses. The objective is to compare perioperative bleeding in major laminectomy between patients receive doubles doses of tranexamic acids (15 mg/kg and 15 mg/kg) with who receive pacebo (0.9% NaCl).
The purpose study are to evaluate the efficacy of Papacarie® for caries removal in comparison to the conventional drilling method.
The study was done to: - test a strategy of using a resistance test to choose anti-HIV drugs - see how well combinations of new anti-HIV drugs work to lower HIV infection - see if taking new anti-HIV drugs together is safe and tolerable - see if text messages improve people's anti-HIV drug-taking behavior (only at sites participating in the adherence study) - in people taking certain combinations of anti-HIV drugs with an anti-TB drug, compare how these drugs act in the body - to see how people do after they stop having frequent clinic visits as part of a research study
Reduced 4-dose intramuscular rabies vaccination schedule was announced by US-ACIP and WHO to be one of the post-exposure prophylaxis regimens. However, concurrent usage of this regimen with rabies immunoglobulin have never been studied in the aspect that the immunity level would above the protective level required by WHO (0.5 IU/ml) for at least a year period. This study would access this subject.
The overall aim of the BREATHER trial is to evaluate the role of Short-Cycle Therapy (SCT) in the management of HIV-infected young people who have responded well to antiretroviral therapy (ART) and to determine whether young people with chronic HIV infection undergoing Short-Cycle Therapy of five days on ART and two days off maintain the same level of viral load suppression as those on continuous therapy, over 48 weeks. To assess the advantages and disadvantages of the strategy, the incidence of toxicities, immunological control, resistance mutations, acceptability, quality of life and adherence to the randomised strategy will also be compared. Importantly, because of insufficient data on short-term viral load rebound after stopping ART in this population, the trial will incorporate an initial pilot phase in selected centres, to assess the safety of the SCT strategy by evaluating detailed HIV-1 RNA profiles of participants on the SCT strategy.
In camps for displaced persons located along the Thai-Myanmar border, mefloquine and artesunate combination therapy has been used since 1992. In vivo efficacy of a 3 day regimen of mefloquine + artesunate (MAS3) has been monitored regularly since its introduction in 1992. In 2009 Carrara et al summarised the in vivo PCR-adjusted cure rates at Day 42 and Day 63 in patients treated with MAS3 between 1995 and 2005, as well as the in-vitro parasite susceptibility to MAS3 during that same period, and the changes in pfmdr1 copy numbers.The proportion of patients with parasitaemia persisting on day-2 increased significantly from 4.5% before 2001 to 21.9% after 2002 (p<0.001). Delayed parasite clearance was associated with increased risk of developing gametocytaemia (AOR = 2.29; 95% CI, 2.00-2.69, p = 0.002). MAS3 efficacy declined slightly but significantly (Hazards ratio 1.13; 95% CI, 1.07-1.19, p<0.001), although efficacy in 2007 remained well within acceptable limits: 96.5% (95% CI, 91.0-98.7). The proportion of infections caused by parasites with increased pfmdr1 copy number rose from 30% (12/40) in 1996 to 53% (24/45) in 2006 (p = 0.012, test for trend). Evidence of reduced susceptibility to artemisinins in Western Cambodia was first reported in January 2007. Artemisinin resistance was manifest by a marked slowing of parasite clearance. A more recent analysis of parasite clearance data collected prospectively in patients with uncomplicated hyperparasitaemic malaria has shown a progressive decline in parasite clearance rates over the last decade suggesting a decline following the same trajectory as in Western Cambodia but with a time lag of a few years. Surveillance data collected in 2011 have shown a dramatic and worrying decline in efficacy of MAS3, albeit in a small number of patients. This decline in efficacy of mefloquine + artesunate is likely to be attributable to reduced parasite susceptibility to mefloquine. The other fixed dose combinations available dihydroartemisinin-piperaquine (DP) is the best option to replace mefloquine-artesunate since it is thought that it remains effective in the presence of high pfmdr1 copy numbers. In addition DP is administered once daily and needs no special dietary modification to ensure adequate absorption. In this study it is hypothesised that efficacy of DP (estimated to be 95%) will be significantly higher than that of MAS3 (estimated to be 65%), therefore the investigators propose to conduct a randomised controlled trial between DP and MAS3 for the treatment of P.falciparum.
In Southeast Asia, Plasmodium vivax (Pv) infection reaches 50-80% and bears a greater burden of disease than Plasmodium falciparum (Pf). As control over Pf improves, Pv will assume increasingly larger percentages of malaria prevalence. The chronicity of Pv, due to the latent liver stage (hypnozoite) not eradicated by chloroquine, causes recurring disability and compounds the economic burden of those with symptomatic disease. The only widely available treatment for hypnozoites is primaquine, which, because of challenges with tolerability, safety in G6PD deficient persons, and compliance, is not commonly prescribed for the treatment of Pv. Currently, chloroquine is used for the treatment of the blood stages of Pv, however, there are concerns about increasing parasite resistance. Alternative treatments, such as artesunate, should be considered in the future of the treatment of blood stage Pv. The use of primaquine in the treatment of hypnozoites (radical cure) should be emphasized so that transmission of Pv can be controlled. This study aims to determine the optimal primaquine regimen for radical cure of Plasmodium vivax. Chloroquine is currently the standard of treatment for Plasmodium vivax. Chloroquine may have synergistic effects when used with primaquine and due to its long half-life may delay the first relapse of vivax malaria. In contrast, artesunate does not have documented interactions with primaquine and has a very short half-life, thus, presumably will have no impact on first relapse. Combining primaquine with these two anti-malarials may lead to an alternative regimen for Pv infection and changing the primaquine dosing regimen may lead to a more practical and efficacious therapy.
The purpose of this study is to evaluate the long term safety and tolerability of fostamatinib in patients in Asia with rheumatoid arthritis (RA).
