Antimicrobial therapy of leptospirosis.
    Current opinion in infectious diseases, 2006, Volume: 19, Issue:6

    Leptospirosis is an important but often overlooked zoonotic disease that can cause significant morbidity and mortality. The optimal antimicrobial treatment for this disease has not been established. This review summarizes the most recent literature pertaining to the use of antimicrobial agents in the treatment of leptospirosis.. Leptospira are highly susceptible to a wide variety of antimicrobials in vitro. Despite this, it is not clear what the best choice of antimicrobial agents is for human disease. Based on the best available literature, the current choices of treatment for leptospirosis include penicillin, doxycycline, cefotaxime, ceftriaxone and azithromycin. Penicillin has long been considered the treatment of choice. Doxycycline is a reasonable alternative, but concerns exist regarding its use in all patients. Recent trials have demonstrated that cefotaxime and ceftriaxone are also acceptable agents. For a variety of reasons, these may be the preferred agents at this time. Azithromycin appears promising for the treatment of less severe disease. Another option for treating leptospirosis is the fluoroquinolone antimicrobials, although adequate human trials are lacking to fully support their use.. Leptospirosis is an important cause of morbidity and mortality worldwide. Despite this, the optimal treatment is not fully defined.

Comparison of azithromycin vs doxycycline prophylaxis in leptospirosis, A randomized double blind placebo-controlled trial.
    Journal of infection in developing countries, 2018, 11-30, Volume: 12, Issue:11

    Leptospirosis is an important zoonotic disease in paddy field with 29.5% prevalence rate in Mazandaran province and 4% to 52% mortality rate among hospitalized patients. Prevention is an important strategy for the control of this disease. This study aimed to compare the prophylactic effect of azithromycin versus doxycycline against leptospirosis in an endemic area in north of Iran.. In this randomized double-blind placebo-controlled trial, paddy field workers (n = 187) were randomized to receive azithromycin (500mg weekly), doxycycline (200 mg weekly) or placebo starting one week before exposure to paddy field, during and to four weeks after. Paddy field workers aged 18- 65 years who signed the informed consent form were assessed for signs and symptoms of leptospirosis in addition to serologic evidence of the disease 6th and 12th week. Data were analyzed with SPSS version 13 using Chi-square and Fisher exact test and ANOVA.. From June to September 2016, 187 participants were entered the study to receive azithromycin (n = 66), doxycycline (n = 71) or placebo (n = 50). In terms of preventing against clinical leptospirosis, there was not any significant difference between three arms, though there was statistically significant difference of seropositivity after 6 and 12 weeks in comparison to baseline among all three groups (P = 0.029) and between active treatment (eg. azithromycin and doxycycline) groups and placebo group (P = 0.01).. Azithromycin like doxycycline decreased seropositivity without significant effect on clinical leptospirosis.

Doxycycline versus azithromycin for treatment of leptospirosis and scrub typhus.
    Antimicrobial agents and chemotherapy, 2007, Volume: 51, Issue:9

    Leptospirosis and scrub typhus are important causes of acute fever in Southeast Asia. Options for empirical therapy include doxycycline and azithromycin, but it is unclear whether their efficacies are equivalent. We conducted a multicenter, open, randomized controlled trial with adult patients presenting with acute fever (<15 days), without an obvious focus of infection, at four hospitals in Thailand between July 2003 and January 2005. Patients were randomly allocated to receive either a 7-day course of doxycycline or a 3-day course of azithromycin. The cure rate, fever clearance time, and adverse drug events were compared between the two study groups. A total of 296 patients were enrolled in the study. The cause of acute fever was determined for 151 patients (51%): 69 patients (23.3%) had leptospirosis; 57 patients (19.3%) had scrub typhus; 14 patients (4.7%) had murine typhus; and 11 patients (3.7%) had evidence of both leptospirosis and a rickettsial infection. The efficacy of azithromycin was not inferior to that of doxycycline for the treatment of both leptospirosis and scrub typhus, with comparable fever clearance times in the two treatment arms. Adverse events occurred more frequently in the doxycycline group than in the azithromycin group (27.6% and 10.6%, respectively; P = 0.02). In conclusion, doxycycline is an affordable and effective choice for the treatment of both leptospirosis and scrub typhus. Azithromycin was better tolerated than doxycycline but is more expensive and less readily available.

Tropical diseases in the ICU: A syndromic approach to diagnosis and treatment.
    Journal of critical care, 2018, Volume: 46

    Tropical infections form 20-30% of ICU admissions in tropical countries. Diarrheal diseases, malaria, dengue, typhoid, rickettsial diseases and leptospirosis are common causes of critical illness. Overlapping clinical features makes initial diagnosis challenging. A systematic approach involving (1) history of specific continent or country of travel, (2) exposure to specific environments (forests or farms, water sports, consumption of exotic foods), (3) incubation period, and (4) pattern of organ involvement and subtle differences in manifestations help in differential diagnosis and choice of initial empiric therapy. Fever, rash, hypotension, thrombocytopenia and mild derangement of liver function tests is seen in a majority of patients. Organ failure may lead to shock, respiratory distress, renal failure, hepatitis, coma, seizures, cardiac arrhythmias or hemorrhage. Diagnosis in some conditions is made by peripheral blood smear examination, antigen detection or detection of microbial nucleic acid by PCR. Tests that detect specific IgM antibody become positive only in the second week of illness. Initial therapy is often empiric; a combination of intravenous artesunate, ceftriaxone and either doxycycline or azithromycin would cover a majority of the treatable syndromes. Additional antiviral or antiprotozoal medications are required for some specific syndromes. Involving a physician specializing in tropical or travel medicine is helpful.

Antimicrobial susceptibilities of geographically diverse clinical human isolates of Leptospira.
    Antimicrobial agents and chemotherapy, 2008, Volume: 52, Issue:8

    Although antimicrobial therapy of leptospirosis has been studied in a few randomized controlled clinical studies, those studies were limited to specific regions of the world and few have characterized infecting strains. A broth microdilution technique for the assessment of antibiotic susceptibility has been developed at Brooke Army Medical Center. In the present study, we assessed the susceptibilities of 13 Leptospira isolates (including recent clinical isolates) from Egypt, Thailand, Nicaragua, and Hawaii to 13 antimicrobial agents. Ampicillin, cefepime, azithromycin, and clarithromycin were found to have MICs below the lower limit of detection (0.016 microg/ml). Cefotaxime, ceftriaxone, imipenem-cilastatin, penicillin G, moxifloxacin, ciprofloxacin, and levofloxacin had MIC(90)s between 0.030 and 0.125 microg/ml. Doxycycline and tetracycline had the highest MIC(90)s: 2 and 4 microg/ml, respectively. Doxycycline and tetracycline were noted to have slightly higher MICs against isolates from Egypt than against strains from Thailand or Hawaii; otherwise, the susceptibility patterns were similar. There appears to be possible variability in susceptibility to some antimicrobial agents among strains, suggesting that more extensive testing to look for geographic variability should be pursued.

Effect of timing and duration of azithromycin therapy of leptospirosis in a hamster model.
    The Journal of antimicrobial chemotherapy, 2007, Volume: 59, Issue:1

    Azithromycin is not associated with significant adverse effects or restricted usage in certain populations unlike standard antileptospirosis agents. In this study, the utility of short courses of azithromycin in treating or preventing leptospirosis was investigated in a lethal hamster model.. All hamsters were infected intraperitoneally with 10(5) leptospires. In experiment one, animals received 5 mg/kg of doxycycline or 10 mg/kg of azithromycin via intraperitoneal injection beginning on the second day after infection and continuing once daily for 1, 2, 3 or 5 days. In experiment two, animals received 1 or 2 day courses of azithromycin initiated 2 or 4 days following infection, or 4 days prior to infection.. All untreated control animals died between the sixth and ninth day following infection. In experiment one, survival rates in the doxycycline groups were 0, 50, 80 and 100% for those animals treated for 1, 2, 3 and 5 days, respectively. Except for the 1 day treatment group (which had an 80% survival), there was 100% survival in all azithromycin-treated groups. In experiment two, all animals treated after infection survived until study completion. No animals survived with 1 day of therapy started 4 days prior to infection while only 20% survived if they received 2 days.. These results suggest short-course therapy with azithromycin, even started well after infection, is efficacious in preventing mortality from acute leptospirosis.

Efficacy of macrolides and telithromycin against leptospirosis in a hamster model.
    Antimicrobial agents and chemotherapy, 2006, Volume: 50, Issue:6

    Human studies support the use of beta-lactams and tetracyclines in the treatment of leptospirosis. Additional agents from these and other classes of antimicrobials also have in vitro activity against Leptospira species, though corroborating in vivo data are limited or lacking. We evaluated the therapeutic efficacy of azithromycin, clarithromycin, and telithromycin in a lethal hamster model of leptospirosis using Leptospira interrogans serogroup Canicola serovar Portlandvere. A range of dosages for each antimicrobial was given to the infected animals on days 2 through 7 (5 days) of the 21-day survival model. All untreated control animals survived less than 10 days from infection. Ninety to 100% of doxycycline controls, treated for 5 days with 5 mg/kg of body weight of drug, survived to 21 days. Treatment with azithromycin (daily dose: 6.25, 12.5, 25, 50, 100, or 200 mg/kg) resulted in 100% survival at all evaluated doses. Animals receiving 20 mg/kg or more of clarithromycin (daily dose: 1, 5, 10, 15, 20, 40, 60, or 100 mg/kg) had improved survival. Ninety-eight percent of animals treated with telithromycin (daily dose: 1, 5, 10, 15, 20, or 40 mg/kg) survived. We conclude that all agents tested have demonstrated in vivo efficacy in treating acute leptospirosis. These results provide support for further evaluation of macrolide and ketolide antimicrobial agents in human trials.
