==Treatment==
==Overview==
Leptospirosis treatment is a relatively complicated process comprising two main components - suppressing  the causative agent and  fighting possible complications. [[Aetiotropic]] drugs are  [[antibiotics]], such as [[doxycycline]], [[penicillin]], [[ampicillin]], and [[amoxicillin]] (doxycycline can also be used as a [[prophylaxis]]). There are no human [[vaccine]]s; animal vaccines are only for a few strains, and are only effective for a few months.  Human therapeutic dosage of drugs is as follows: doxycycline 100 mg orally every 12 hours for 1 week or penicillin 1-1.5 MU every 4 hours for 1 week.  Doxycycline 200-250 mg once a week is administered as a [[prophylaxis]]. In dogs, penicillin is most commonly used to end the leptospiremic phase (infection of the blood), and doxycycline is used to eliminate the [[asymptomatic carrier|carrier]] state.
All patients with suspected leptospirosis require [[antimicrobial]] therapy. [[Antimicrobial drug|Antimicrobial]] therapy is the mainstay of therapy for Leptospirosis. [[Antimicrobial]] therapies include either [[penicillin]], [[ampicillin]], [[doxycycline]] or [[ceftriaxone]]. Patients with [[meningitis]] often require high-dose [[penicillin]], whereas patients with [[Weil's disease]] often require either [[azithromycin]] or [[doxycycline]]. Supportive measures include [[detoxification]] and normalization of [[electrolyte]] imbalances. [[Dialysis]] is reserved for patients with severe disease who fail antimicrobial therapy.


Supportive therapy measures (esp. in severe cases) include [[detoxication]] and normalization of the [[Electrolyte#Physiological importance|hydro-electrolytic balance]]. Glucose and salt solution infusions may be administered; [[dialysis]] is used in serious cases. Elevations of serum potassium are common and if the potassium level gets too high special measures must be taken. Serum phosphorus levels may likewise increase to unacceptable levels due to renal failure. Treatment for hyperphosphatemia consists of treating the underlying disease, [[dialysis]] where appropriate, or oral administration of [[calcium carbonate]], but not without first checking the serum calcium levels (these two levels are related). [[Corticosteroid]]s administration in gradually reduced doses  (e.g., [[prednisolone]] starting from 30-60 mg) during 7-10 days is recommended by some specialists in cases of severe haemorrhagic effects.
==Medical Therapy==
All patients with suspected leptospirosis require antimicrobial therapy. For effective treatment of leptospirosis, [[antibiotics]] should be used within 5th day after the onset of symptoms and as soon as the diagnosis of leptospirosis is suspected without waiting for the laboratory results.<ref>{{cite book | last = LastName | first = FirstName | title = Human leptospirosis : guidance for diagnosis, surveillance and control | publisher = World Health Organization | location = Geneva | year = 2003 | isbn = 9241545895 }}</ref> Best initial treatment for severe leptospirosis is penicillin. For less severe form, drugs such as [[amoxicillin]], [[ampicillin]], [[doxycycline]] or [[erythromycin]] can be used.

Overview

All patients with suspected leptospirosis require antimicrobial therapy. Antimicrobial therapy is the mainstay of therapy for Leptospirosis. Antimicrobial therapies include either penicillin, ampicillin, doxycycline or ceftriaxone. Patients with meningitis often require high-dose penicillin, whereas patients with Weil's disease often require either azithromycin or doxycycline. Supportive measures include detoxification and normalization of electrolyte imbalances. Dialysis is reserved for patients with severe disease who fail antimicrobial therapy.

Medical Therapy

All patients with suspected leptospirosis require antimicrobial therapy. For effective treatment of leptospirosis, antibiotics should be used within 5th day after the onset of symptoms and as soon as the diagnosis of leptospirosis is suspected without waiting for the laboratory results.[1] Best initial treatment for severe leptospirosis is penicillin. For less severe form, drugs such as amoxicillin, ampicillin, doxycycline or erythromycin can be used. Other drugs of choice which are effective, include third-generation cephalosporins such as ceftriaxone and cefotaxime, and quinolone antibiotics.[2]

Supportive Care

Supportive care for patients with leptospirosis includes the following:[3][4]

Antimicrobial regimen

Special Considerations

  • 1. Meningitis due to leptospirosis[3]
  • Preferred regimen: Penicillin 5 million units IV q6h for 7 days
  • Alternative regimen: Ampicillin 0.5-1 g IV q6h for 7 days OR Doxycycline 100 mg IV/PO up to 100 mg q12h for 7 days OR Ceftriaxone 1 g IV q24h for 7 days
  • Preferred regimen: Azithromycin 1 g IV once THEN 500 mg IV q24h for 2 days
  • Alternative regimen:Doxycycline 100 mg IV/PO up to 100 mg q12h for 7 days

Dialysis

  • Dialysis is often reserved to patients who fail to respond to antimicrobial therapy.[3][4]
