Malaria in HIV-infected patients in a nonendemic setting

Imported malaria: A 20-year retrospective study from a tertiary public hospital in Brussels, Belgium

BACKGROUND

Malaria continues to cause a significant number of infections in non-endemic regions. In this paper, we describe the epidemiological trend and morbidity of imported malaria diagnosed in a tertiary hospital in Brussels.

METHODS

We conducted a retrospective study describing a cohort of malaria episodes (in- and outpatients) at Centre Hospitalier Universitaire Saint-Pierre from 1998 to 2017. Epidemiological and clinical data were collected by reviewing medical files.

RESULTS

A total of 1011 malaria episodes were analyzed. Median age at diagnosis was 35 years, and 66 % of patients were men (672/1011). Malaria cases significantly increased over the two decades (from 17 in 1998 to 79 in 2017). Plasmodium falciparum malaria was most often diagnosed (846/935, 89 %), primarily from Central (530/935, 57 %) and West Africa (324/935, 35 %). Many cases (383/764, 50 %) were diagnosed in patients "visiting friends and relatives". HIV-infected and other immunocompromised patients were significantly more likely to present with severe malaria (at least one severity criteria as defined by the WHO) compared to other patients (24/57, 42 % vs 138/732, 19 %, p < 0.01 and 15/21, 71 % vs 147/767, 19 %, p < 0.001). Severe malaria was diagnosed in 16.9 % and the mortality rate was low (5/1011, 0.5 %).

CONCLUSION

Imported malaria increased over the years with a large, albeit stable number of cases diagnosed in patients visiting friends and relatives. These findings, along with the high rate of severe malaria in HIV and immunocompromised patients, underscore an urgent need for strengthened malaria surveillance and targeted preventive interventions.

Do people living with HIV travel safely? Assessment of travel patterns and advice-seeking behaviour in a cohort of people living with HIV in Belgium

OBJECTIVES

Pre-travel counselling has demonstrated its efficacy in decreasing travel-related health complications. The current profile of people living with HIV (PLWH) in Europe [increasing age, visiting friends and relatives (VFR)] makes pre-travel counselling crucial. We aimed to survey the self-reported travel patterns and advice-seeking behaviour among PLWH followed up at the HIV Reference Centre (HRC) of Saint-Pierre Hospital, Brussels.

METHODS

A survey was conducted in all PLWH presenting at the HRC from February to June 2021. The survey covered demographic elements, travel and pre-travel consultation habits over the last 10 years, or since the diagnosis of HIV if it was made less than 10 years earlier.

RESULTS

The survey was completed by 1024 PLWH (35% women, median age 49 years, the majority being virologically controlled). A substantial number of PLWH were involved in VFR travel in low-resource countries and 65% sought pre-travel advice before travelling: if not, it was because they did not know it was necessary (91%).

CONCLUSION

Travel is common among PLWH. Raising awareness of the importance of pre-travel counselling should be a routine part of every healthcare encounter and especially during regular contact with HIV physicians.
