| NCT01014260 ↗ | Doxycycline Outcomes in Lupus Erythematosus | Withdrawn | Johns Hopkins University | Phase 4 | 2010-09-01 | Cardiovascular disease, specifically from atherosclerosis, is the major cause of mortality in SLE in developed countries. In a recent study the investigators have shown that high sensitivity C reactive protein (hs-CRP) is higher in SLE patients with (versus without) coronary calcium, a measure of subclinical atherosclerosis. In an ongoing two year intervention trial of atorvastatin, the investigators will determine if statins retard coronary calcium and reduce hs-CRP. However, 10% of the patients in the trial were intolerant of statins. The investigators want to now investigate whether there are additional, and potentially safer ways, to reduce hs-CRP in SLE. In this study, the investigators will determine if doxycycline reduces hs-CRP and other vascular inflammatory markers including interleukin 6 (IL-6), soluble vascular cell adhesion molecule (sVCAM-1), soluble inter cell adhesion molecule (s-ICAM-1) and matrix metalloproteinase 9 (MMP-9) in SLE. |
| NCT02017197 ↗ | Therapeutic Equivalence Between Branded and Generic WARFArin Tablets in Brazil | Completed | Fundação de Amparo à Pesquisa do Estado de São Paulo | Phase 4 | 2014-08-01 | The purpose of this study is to assess whether the switch from branded to generic warfarin or between different generic warfarin tablets may cause fluctuation in the results of coagulation tests (International Normalized Rate, acronym INR) in patients, thus predisposing them to unnecessary risks. |

| NCT02726646 ↗ | Evaluation of Local Doxycycline in Smokers With Chronic Periodontitis | Completed | Pontificia Universidade Catolica de Sao Paulo | Phase 2 | 2015-06-01 | Summary The aim of this study is to evaluate through clinical, microbiological and immunological parameters using PLGA microspheres (lactic-co-glycolic acid polyacid) containing doxycycline in periodontal therapy in smokers with chronic periodontitis. For this study, 40 patients will be selected, with an average age between 30 and 59 years old of both genders (male and female), who spontaneously seek the clinic graduate of the Piracicaba Dental School -FOP / UNICAMP, and exhibiting at least four bleeding sites, including 2 sites with a probing depth (PD) between 5 and 6 mm and two sites PS ≥7 mm in uniradiculares teeth. Patients should have a minimum of 20 teeth. Will be excluded from relevant systemic disease carriers or antibiotics used in the 6 months preceding the study. All patients will receive oral hygiene instruction and will undergo a pre-treatment, which will be held supragingival sweeps and removal of plaque retentive factors. Patients will be divided into 2 groups (DB + DOX: Debridement + Doxycycline, test group and DB: only debridement, control group) of 20 patients who will receive the following treatments: periodontal debridement ultrasound for 45 minutes associated with the local administration of 1 mg microspheres containing doxycycline, or just mechanical debridement, for each selected site. Will be assessed the following clinical parameters: gingival index (GI) Plaque Index (PI), Bleeding on Probing (BOP), Position of the gingival margin (PGM), Probing Depth (PD) and Relative Clinical Attachment Level (RCAL). The microbiological evaluation will be made by means of polymerase chain reaction - real time ( "real time" - PCR) to detect bacteria: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans and Prevotella intermedia. The enzyme immunoassay (LUMINEXMAGPIX) allow the detection of cytokine levels of GM-CSF, INF-γ, IL-10, IL-12, IL-13, IL-1β, IL-4, IL-6, IL-8 and TNF-α. The analysis of the proteolytic enzyme activity is accomplished by using zymography to assess MMP-8 and MMP-9. The described parameters will be evaluated at baseline, 45 and 90 days after the initial visit. The results are compared statistically by analysis of variance with repeated measures with 5% significance level. |
