8.1.2. Acute lung injury and respiratory distress
There have been over 20 reports of well-defined ALI and ARDS as a single
complication of PCR-confirmed P. vivax . Initial reports were mostly man-
aged in non-endemic country hospitals, with a very low case-fatality rate
and with the majority occurring after commencement of antimalarial drug
treatment (see Price et al., 2007a ; Tan et al., 2008 ; Habib and Singh, 2004 ;
Lawn et al., 2003 ; Pukrittayakamee et al., 1998 ; Torres et al., 1997 ; Kotwal
et al., 2005 ; Maguire et al., 2005 ; Curlin et al., 1999 ; Carlini et al., 1999 ;
Munteis et al., 1997 ; Saleri et al., 2006 ; Tanios et al., 2001 ; Kumar et al.,
2007 ; Agarwal et al., 2007 ; Taylor et al., 2012 for review). One report from
India of a 20-year-old woman with PCR- and autopsy-confirmed vivax
malaria documents presentation with ARDS pre-treatment, resulting in a
fatal outcome ( Valecha et al., 2009 ).
More recently reported cases of ALI/ARDS in adults have mostly been
part of larger series of severe vivax malaria from endemic settings, generally
with less-clearly defined ARDS criteria, occurring as part of multiple organ
dysfunction/failure ( Kochar et al., 2005 , 2009 ; Andrade et al., 2010 ; Alexan-
dre et al., 2010 ). Clinical ARDS/'respiratory failure' occurred in 10-32% of
patients with severe malaria and had a case-fatality rate of 50-67% ( Kochar
et al., 2005 , 2009 ; Andrade et al., 2010 ; Alexandre et al., 2010 ), much higher
than the very low fatality rate seen in reports of single-organ ARDS ( Taylor
et al., 2012 ).
In the Brazilian autopsy series, 15 of 17 (88%) had respiratory distress
before death, again mostly commencing after the start of antimalarial drug
treatment ( Lacerda et al., 2012 ). ARDS and/or lung oedema was identified
as the commonest complication contributing to death, occurring in six
overall (35%) and in three of the four (75%), in whom vivax was considered
the direct cause of death ( Lacerda et al., 2012 ). In two of the latter cases,
lung oedema occurred in conjunction with other major pathology (one
each with coma/encephalitis and splenic rupture) ( Lacerda et al., 2012 ).
8.1.3. Coma and other vivax-associated neurological complications
Coma is a common complication of P. falciparum infection comprising
approximately 50% of adult severe falciparum malaria complications
( Yeo et al., 2007 ; Dondorp et al., 2008 ; Hien et al., 1996 ). In contrast,
coma is a less-common manifestation of vivax malaria. From 1921 to
2011, over 100 cases of P. vivax monoinfection in adults and children
associated with coma were described in reports or series ( Kochar et al.,
2005 , 2009 , 2010 ; Lampah et al., 2011 ; Tanwar et al., 2011 ; Romanenko,
