BACKGROUND: Significant morbidity can occur in untreated patients with Lyme disease. Currently the Infectious Disease Society of America (IDSA) recommends treatment only in the presence of erythema migrans or seropositivity with symptoms of systemic disease. Although the IDSA does not recommend antimicrobial prophylaxis to patients with a documented tick bite, it may be possible to prevent Lyme disease by treating patients prophylactically after removing the tick Ixodes scapularis. POPULATION STUDIED: Study subjects were recruited from Westchester County, New York, an area in which Lyme disease is hyperendemic. Inclusion criteria included age older than 12 years with a history of having removed an Ixodes scapularis tick within 72 hours of enrollment. Subjects whose ticks were later shown to not be Ixodes scapularis were included only in the analysis of safety. Other exclusion criteria included having been vaccinated against Lyme disease, having a rash consistent with erythema migrans, actively taking or having recently completed a course of antibiotics effective against Borrelia burgdorferi, being pregnant or lactating, and not having the tick available for analysis. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Know the risks and potential benefits of clinical studies and talk to your health care provider before participating. It would mimic the conditions that would occur outside a clinical trial. After consent and enrolment, all procedures will be guided by the Australian STI Management Guidelines. All enrolling participants will be offered daily doxycycline 100mg 4. Listing a study does not mean it has been evaluated by the U. All participants will be invited to complete a survey in every 3 months time for 12 months dated from participation. All follow-up information will be collected through electronic data capture to allow accurate and timely analyses. Data collection will be from (i) medical records (ii) online self-completed questionnaire The last decade has seen increasing rates of bacterial STIs in Australia in gay and bisexual men in particular. This study is a non-randomized observational cohort trial using before and after comparison to evaluate intervention 2. Although STIs are easy to diagnose and treatment is effective, untreated STIs can cause significant health issues. Previous research has shown that taking two100mg doxycycline tablets within 24 hours of sex as prophylaxis reduces syphilis and chlamydia significantly. Also a pilot trial conducted in the US suggested that using 100mg doxycycline as prophylaxis reduced the incidence of gonorrhoea, syphilis and chlamydia. Thus the question of whether taking doxycycline daily in high risk population would reduce the rate of STIs arose.

Pre-exposure antibiotic prophylaxis is NOT ROUTINELY RECOMMENDED. Doxycycline hydrochloride and hyclate 200 mg once weekly, to begin 1 to 2 days. Single dosage of doxycycline for prophylaxis against leptospiral infection and leptospirosis during urban flooding in southern Thailand A non-randomized. This study was conducted to investigate the protective efficacy of a single dosage of 200 mg doxycycline against leptospiral infection and leptospirosis and associated risk factors among residents exposed to flooding in southern Thailand. Of 641 participants, 600 received doxycycline while 41 did not. Twenty two participants were infected with , resulting a protective efficacy of 76.8% (95% confidence interval [CI] = 34.3%–92.0%). Four who received doxycycline and two who did not, developed leptospirosis, resulting a protective efficacy of 86.3% (CI = −9.8%–98.2%). Among the participants with laceration wound, the protective efficacy for leptospiral infection was 92.0% (CI = 81.2%–96.6%) and for leptospirosis was 95.6% (CI = 78.2%–99.3%). Among the participants exposed to flood water less than or equal to 3 h per day, the protective efficacy for leptospiral infection was 89.2% (95% CI 63.6%–96.67%). A single dosage of 200 mg doxycycline for prophylaxis might be effective for preventing leptospirosis among flood victims with laceration wound after recent flood exposure. The use of doxycycline as a prophylactic antibiotic against scrub typhus was investigated in a prospective, randomized, double-blind study. Twenty volunteers were divided into two similar groups. Beginning three days before exposure to , and continuing for six weeks after exposure, one group received weekly 200-mg oral doses of doxycycline and the other group received a placebo. Nine of 10 doxycycline-treated subjects remained well during prophylaxis but developed antibody to scrub typhus, whereas nine of 10 subjects given the placebo required treatment for scrub typhus. Therefore, the efficacy of the regimen in preventing scrub typhus was 89070 (eight cases prevented of nine expected). Ten days after successfully completing prophylaxis, eight of nine subjects reported minor self-limiting symptoms. A single dose of doxycycline was given on day 3 of illness to volunteers who developed scrub typhus.
