Malaria and leptospirosis are both common in the tropics. Simultaneous infections are possible, although not previously reported. We report cases of malaria from an area of Thailand on the Thailand-Myanmar border with compelling serologic evidence of simultaneous acute leptospirosis.
STUDY ABSTRACT:
One was a case of infection with Plasmodium falciparum with acute and convalescent microscopic agglutination test (MAT) titers for Leptospira serovar icterohaemorrhagiae of 1:200 and 1:1,600, respectively. The other was a case of infection with P. vivax that seroconverted to a titer of 1:3,200 for Leptospira serovar bataviae. Additionally, there were probable cases of leptospirosis with malaria detected.
Cont…
Management of dual infections is complicated by their similar clinical presentations, and because the confirmatory diagnosis of malaria is readily available as opposed to that of leptospirosis. Treatment focusing on malaria mono-infections instead of dual infections could result in a delay of specific therapy for leptospirosis and possible consequences of serious complications.
Cont..
Confirmation of co-infections with leptospirosis and malaria warrants careful diagnostic evaluation and presents a therapeutic dilemma among febrile patients in Sangkhlaburi. In the case of P. falciparum, artesunate-doxycycline therapy, one of the regimens of choice for this region of Thailand known for its high prevalence of multidrug-resistant malaria, will cover both diseases. For P. vivax, and in places where doxycycline is not routinely used for the treatment of P. falciparum malaria, prescription of doxycycline for a case with any index of suspicion should be considered

1.DOXYCYCLINE is effective against both Malaria and leptospirosis. So adding Doxycycline with Chloroquine or Quinine will be effective in treatment of both illness simultaneously
2. In endemic areas of Malaria and Leptospirosis identifying and treating co infection is essential for rapid recovery and to prevent complications.
CONCLUSION
