Fever is a common symptom of malaria. Antipyretic drugs (fever-relieving medicines) and physical measures (such as tepid sponging) are widely used by caregivers and health care workers to treat fever in adults and children with malaria. Some researchers have questioned the belief that treating fever with antipyretic drugs is beneficial. They suggest that it may actually prolong the time taken for the malaria parasite to be cleared from the blood system. This review looked for evidence from appropriate types of research that addressed these issues. We found only a few small trials and could not obtain sufficient information from these trials to reach a conclusion on whether the antipyretic drugs actually help to resolve malaria symptoms or prolong the illness.

Fever is common in malaria, and drugs and sponging are widely used for symptomatic relief. Some researchers have suggested that fever reduction may prolong malaria illness.
Ciljevi
We aimed to assess whether treatments to reduce fever in malaria influence the course of the illness.
Metode pretraživanja
We searched the Cochrane Infectious Diseases Group Trial Register (June 2012), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 6, 2012), MEDLINE (1966 to June 2012); EMBASE (1980 to June 2012) and LILACS (June 2012). We contacted researchers and organisations working in the field to enable us identify other unpublished or ongoing trials.
Kriteriji odabira
Randomized controlled trials of fever reduction measures in adults or children with confirmed malaria.

Inclusion criteria were independently applied by two authors. We extracted data from trials that met our pre-specified criteria using a standard data extraction form. Mean differences with 95% confidence intervals (CI) were calculated for continuous data. GRADE was used to evaluate and summarize the quality of the evidence.
Glavni rezultati
Ten randomized controlled trials with 990 participants including both adults and children met our inclusion criteria. All were small scale trials with methodological limitations and were conducted in a variety of patients. Some trials detected an impact of antipyretic drugs on fever clearance time, while others did not. Regarding parasite clearance,no clear influence of anti-pyresis was demonstrated (six trials, 423 participants, very low quality of evidence). No difference in the number or severity of adverse events between antipyretic drugs and control was detected.
Zaključak autora
We do not know whether antipyretics alter parasite clearance time. Whether further trials are worthwhile to investigate this or not would require a judgement of whether this was an important question to resolve using interventional trials.
