Risk testing for HIV serostatus is unlikely to detect more than 20% of HIV-positive pregnant women. Of the 11 pregnant women discovered to be HIV-infected at Port Moresby General Hospital in Papua New Guinea in 1994-95, only four had more than two sexual partners since 1992 and none was an intravenous drug user. The deleterious effect of pregnancy on HIV disease progression appears to be small but variable, with more serious effects in the later stages of disease. The risk of vertical transmission increases when viral loads are high, the general maternal condition is poor, and delivery is preterm. In developing countries, where HIV-infected pregnant women are likely to be malnourished and to have concomitant infections such as malaria and tuberculosis, the risks of preterm labor, small-for-gestational age infants, and chorioamnionitis are increased. HIV-related gynecologic conditions such as pelvic inflammatory disease, vulvovaginal candidiasis, and cervical neoplasia may be resistant to treatment and tend to recur. Pregnancy prevention through effective contraceptive methods such as Depo-Provera and tubal ligation may be more important to HIV-infected women than prevention of viral transmission, especially when both partners are seropositive.

HIV and malaria are two major infections that are responsible for the greatest burden of diseases, morbidity and mortality in the African population. Successful research has been undertaken in Africa into novel means of monitoring HIV disease progression and in identifying vaccine candidates. The role of IgG isotypes in malaria has been investigated, as have parasite adhesion molecules important for pathogenesis. It is hoped that vaccines for malaria will soon prove successful. However, many problems still face immunology research in Africa.

HIV and malaria kill millions of people every year. They share a common geographic distribution, and both cause far more disease and death in sub-Saharan Africa than they do in the rest of the world. Many epidemiologic studies have suggested that HIV and malaria coexist independently, but some recent reports describe synergistic interactions between them. People living with HIV infection who do not have pre-existing immunity to malaria experience a marked increase in malaria severity. But for those who have acquired immunity through natural exposure to malaria, HIV-related immunosuppression is associated with only a modest increase in clinical malaria, which may be explained in part by more frequent nonmalaria febrile episodes. The effect of malaria infection on HIV disease progression due to increased viral replication may be important but has not yet been fully explored.

More than 90% of pediatric HIV infection occurs in sub-Saharan Africa and 75% of these children currently die before their fifth birthday. Most HIV-infected children in Africa rely on district hospitals for HIV treatment, but insufficient attention has been paid to improving HIV/AIDS care at this level. Considerable confusion exists about optimal use of combination antiretroviral treatment, prophylaxis for opportunistic infections and other rational healthcare interventions that can greatly improve the quality of life for these children. A simple and inexpensive infant HIV diagnostic assay and alternative laboratory markers of pediatric HIV disease progression would be highly beneficial. Routine anthropometric and neurodevelopmental assessments could help guide initiation and monitoring of antiretroviral therapy. Even in the absence of antiretroviral therapy, interventions such as immunizations, provision of micronutrients and nutrition counseling, prevention and treatment of opportunistic as well as endemic infections (such as helminths and malaria) can substantially reduce pediatric HIV-related morbidity and mortality. The need for pain relief, palliative care, counseling and emotional support is often underestimated. Surmounting the sense of hopelessness by providing district healthcare workers with training in basic pediatric HIV/AIDS care is an urgent priority.

Reversing the spread of HIV infection and the incidence of malaria constitute two of the Millenium Development Goals. However, despite recent achievements, both diseases still entail global heath problems. Furthermore, their overlapping geographical distribution raises concerns and challenges for potential immunological, clinical and therapeutic interactions. It has been reported that HIV infection increases malaria susceptibility and reduces the efficacy of antimalarial drugs. On the other hand, the effect of malaria on HIV-infected individuals has also been explored, with the parasitic infection increasing the risk of HIV disease progression and mother-to-child transmission of HIV. The spread of malaria and parasite resistance to antimalarials could also be accelerated by HIV-associated immunosuppresion. Current knowledge of the epidemiological, clinical, immunological and therapeutic interactions of the two diseases is reviewed in this article. We focus on the latest available data, pointing out key future research areas and challenges of the field.

HIV infection is widespread throughout the world and is especially prevalent in sub-Saharan Africa and Asia. Similarly, Plasmodium falciparum, the most common cause of severe malaria, affects large areas of sub-Saharan Africa, the Indian subcontinent, and Southeast Asia. Although initial studies suggested that HIV and malaria had independent impact upon patient outcomes, recent studies have indicated a more significant interaction. Clinical studies have shown that people infected with HIV have more frequent and severe episodes of malaria, and parameters of HIV disease progression worsen in individuals during acute malaria episodes. However, the effect of HIV on development of cerebral malaria, a manifestation of P. falciparum infection that is frequently fatal, has not been characterized. We review clinical and basic science studies pertaining to HIV and malaria coinfection and cerebral malaria in particular in order to highlight the likely role HIV plays in exacerbating cerebral malaria pathogenesis.
