| NCT00277147 ↗ | Salmonella Typhi Vi O-Acetyl Pectin-rEPA Conjugate Vaccine | Completed | Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | Phase 1 | 2006-01-09 | This study will evaluate a new (conjugate) vaccine for typhoid fever, which remains a serious disease especially difficult to treat in developing countries. Salmonella typhi, the bacteria causing typhoid fever, have become resistant to several antibiotics increasing the difficulty of treating the disease. The disease may have serious complications effecting bones, brain, and intestines, with permanent injury or death. Methods to control typhoid fever, such as a sanitary water and food supply, along with effective sewage treatment, are not likely to be available soon in those countries. NIH scientists developed a vaccine called Vi, made of a polysaccharide (a chain of linked sugars) from the surface of Salmonella typhi, the bacteria that cause typhoid fever. It has been approved by the World Health Organization and is licensed in 94 countries. It is effective in adults but not in young children. Clinical trials have shown that chemically binding the Vi to a protein to form a "conjugate vaccine" has improved and extended its efficacy to children (conjugate vaccines to other bacteria, notably meningitis causing bacteria have been used extensively and successfully). Now NIH scientists have developed another vaccine for typhoid fever - using a polysaccharide from fruit, known as pectin. The pectin has been chemically treated so that it resembles Vi. The treated pectin, O-acetyl pectin, is bound to a protein; exoprotein A, (rEPA). The result is a conjugate, as was formed for Vi. Similarly to the Vi conjugate it induces antibodies against Salmonella typhi in laboratory animals. If the O-acetyl pectin conjugate proves successful, it will be evaluated in children ages 5 to 14 years old and in infants, toward using it with routine vaccines for infants. Volunteers ages 18 to 45 who do not have an allergy to fruit pectin and who have not been vaccinated against nor had typhoid fever within the last 5 years may be eligible for this study. Volunteers will undergo several tests at their first visit to the clinic for this study. A blood sample (about 2/3 of an ounce) will be taken to test for HIV, hepatitis B and C, complete blood count, liver functions, blood chemistry and pregnancy in women of childbearing age. The blood sample will also be tested for antibodies to Vi, rEPA (the protein of the conjugate), and pectin. There will also be a urine collection for testing. If the laboratory tests are acceptable, volunteers will be asked to return to the clinic on a... |
| NCT00372541 ↗ | Ceftriaxone Versus Chloramphenicol for Treatment of Severe Pneumonia in Children | Completed | Makerere University | Phase 3 | 2006-09-01 | Acute lower respiratory tract infections are a leading cause of morbidity and mortality in sub Saharan Africa. The World Health Organisation (WHO) still recommends intravenous chloramphenicol for the treatment of severe pneumonia in children aged less than five years. However, up to 20% of children fail treatment due to the emergence of resistance by bacteria. Several centers now use ceftriaxone, a third generation cephalosporin, which is reported to be efficacious in the treatment of severe pneumonia. However the high cost of ceftriaxone is too prohibitive to allow for its routine use in resource constrained countries. The purpose of this study is to compare chloramphenicol and ceftriaxone in the treatment of severe pneumonia in children under five. We hypothesize that 92.7% of children who receive once daily intravenous ceftriaxone (75 mg/kg body weight)for 7 days, will recover from severe pneumonia compared to 80.2 % of those who receive intravenous chloramphenicol (25mg/kg body weight/dose every 6 hours for 7 days). |
| NCT00579956 ↗ | A Randomized Double Blinded Comparison of Ceftazidime and Meropenem in Severe Melioidosis | Unknown status | Mahidol University | N/A | 2007-12-01 | Melioidosis, an infection caused by the bacterium Burkholderia pseudomallei, is a major cause of community-acquired septicaemia in northeast Thailand. Common manifestations include cavitating pneumonia, hepatic and splenic abscesses, and soft tissue and joint infections. Despite improvements in diagnostic procedures and treatment, the mortality of severe melioidosis remains unacceptably high - approximately 35% with currently used antibiotics (ceftazidime or co-amoxiclav). There is clear evidence that antibiotics can affect mortality; the use of ceftazidime rather than previous regimens (doxycycline + chloramphenicol + co-trimoxazole) led to a 50% reduction in mortality from 80% to 35%. However, the mortality in the first 48 hours has not been altered by any treatment regimen. A key question is whether alternative antibiotics could improve early outcome. The hypothesis tested is that meropenem is superior to ceftazidime in terms of mortality for the treatment of melioidosis. |
