Rolling back malaria: how well is Europe doing?

Background. The Roll Back Malaria (RBM) initiative has committed itself to halving the worlds's malaria burden by 2010, having adopted five operationally focused 'critical concepts' to guide this task. The focus of RBM's efforts is in the developing world where external support is often required. Malaria was only recently eradicated from Europe, and the continent remains under continual threat of reintroduction. The extent of this threat is examined, and the European response benchmarked against RBM's critical concepts. Methods. The following sources were searched for references using the phrase "imported malaria": RBM, WHO, European Union including Eurosurveillance, and MedLine websites. Links to related articles were followed. Citations were independently assessed by the authors for relevance and inclusion. Results. Only in application of the critical concept "disease surveillance" does the European response seem adequate. Conclusions. Europe should be making greater efforts and considering additional strategies to combat imported malaria.

Early treatment of imported falciparum malaria in the intermediate and intensive care unit setting: an 8-year single-center retrospective study

INTRODUCTION

Imported falciparum malaria is characterized by a broad spectrum of potentially life-threatening complications that may arise even after initiation of appropriate antimalarial drug therapy. Hence, at Heidelberg University Hospital, all patients with newly diagnosed falciparum malaria are initially treated in the intermediate care unit (IMC) or intensive care unit (ICU). The present study was undertaken to evaluate critically the benefit of this strategy, which includes daily consultation with senior specialists in tropical medicine.

METHODS

We conducted a retrospective cohort study at the 14-bed combined IMC/ICU of a 1,685-bed university hospital. A cohort of 122 patients with imported falciparum malaria admitted from 1 January 1996 to 31 December 2003 was included.

RESULTS

Thirty-four patients (27.9%) developed complications, defined according to the current World Health Organization classification. Most patients (80.3%) studied did not take the recommended chemoprophylaxis against malaria. The majority of patients (89.3% [n = 109]) could be adequately treated in the IMC. Life-threatening complications requiring ICU support occurred in 13 patients (10.7%). All complications were successfully managed. Fifty-five patients (45.1%) fulfilling recently published criteria for outpatient treatment had an excellent therapeutic response and did not require ICU support.

CONCLUSION

This retrospective evaluation demonstrated favourable therapeutic results in hospitalized patients with imported falciparum malaria. Both initial treatment in the medical IMC/ICU and close collaboration between intensivists and specialists in tropical medicine may improve disease outcome among affected patients. Prospective studies are needed to confirm these preliminary findings.
