Parasitic etiologies of pulmonary symptoms generally represent some degree of immunocompromise or occur as uncommon presentations of common parasitic infections. In regions where HIV infection is more prominent, PCP probably will be the most common parasitic respiratory disease seen. In geographic regions where helminthic infections are more common, patients with respiratory symptoms and eosinophilia probably will be seen more often and require a search for a specific etiology. In more rare circumstances, travel to an endemic area may suggest a more exotic parasitic etiology for respiratory symptoms.

Recent controlled clinical trials have confirmed the usefulness of aerosolized tobramycin in cystic fibrosis and have emphasized the importance of ensuring adequate lung delivery of inhaled antimicrobials. For purulent tracheobronchitis associated with prolonged mechanical ventilation it has recently been established that it is possible to deliver substantial and measurable doses of medications to the airway via aerosolization, but controlled studies are needed to determine the efficacy and safety of inhaled antibiotic therapy in this setting. However, prophylactic aerosolized antibiotic therapy in an intensive care unit setting may be counterproductive. Aerosolized pentamidine continues to provide prophylaxis against PCP in a substantial minority of subjects with human immunodeficiency virus infection who are intolerant of oral agents. The effectiveness of aerosolized amphotericin B as prophylaxis against aspergillosis in neutropenic patients needs to be evaluated in a large clinical trial. Zanamivir, an inhibitor of neuraminidase, delivered via inhalation, shows promise in the treatment of uncomplicated influenza infection, but more data are needed on its effectiveness and safety in patients with preexisting respiratory disease. The development of new chemical entities, more efficient delivery systems, and more precise measurement of dose-response and regional pulmonary drug distribution of inhaled antimicrobials suggest that this somewhat neglected topic in therapeutics may be about to receive an increased degree of attention.

Over one million children world-wide are living with HIV infection and respiratory disease is the commonest cause of morbidity and mortality in these children. The initial presentation of respiratory infection is usually in infancy or early childhood. There is enormous potential to prevent childhood HIV infection that is being realised in industrialised countries but not yet elsewhere. Increasingly, therefore, the burden of HIV disease is in children living in or from non-industrialised countries. This review describes and contrasts the pattern of respiratory infection from both regions. This pattern has changed with the implementation of PCP prophylaxis and the availability of potent antiretroviral therapy for children in resource-rich countries, such as the UK. More data are required from resource-poor regions such as tropical Africa, but it is clear that the major differences reflect greater background risk for respiratory infection and very limited management options rather than specific aetiology.

Respiratory disease is the commonest cause of morbidity and mortality in HIV-infected children. While the pattern of HIV-related pneumonia in African adults is well documented and is recognised as quite different from that which occurs among HIV-infected adults in high-income regions, less is known of the situation in children. Most children are infected by mother-to-child transmission and presentation of HIV-related pneumonia is often in infancy or early childhood, an age group in which confirmation of the cause of pneumonia is difficult. However, aetiological data are important. Poor response of the infant with severe pneumonia to standard antibiotic (such as chloramphenicol) or of the older child with chronic pneumonia to anti-tuberculosis treatment are two very common clinical dilemmas that many Malawian health workers would recognise. This review aims to present the available data relevant to Malawi, contrast with experience from the developed world and to describe common HIV-related pneumonias such as PCP and LIP. Unlike for adults, the pattern of HIV-related pneumonia in Malawian children may not be so different in cause from that described for children in developed countries prior to the use of PCP prophylaxis and anti-retroviral therapies. The most important contrast is the higher prevalence and poorer outcome.
