A 37-year-old female patient reported marked weight loss, prolonged alopecia, recurrent infections and watery diarrhoea. Examination revealed Salmonella infection, candidiasis and immunological signs of previous toxoplasmosis. Between 1978 and 1981, the patient had had close sexual relations to a patient with haemophilia A. Due to this fact, AIDS was suspected. Serological tests for HIV were not available at the time. The findings in DNA image cytometry (nuclear DNA inclusion bodies, polyploid lymphocyte nuclei and binuclear lymphocytes) suggested a viral infection of the lymphoid cells. Electron microscopy revealed in hepatocytes and cerebral cells intranuclear inclusion bodies whose size and contents were not compatible with an infection caused by cytomegalovirus, herpes virus or Epstein-Barr virus. In autopsy, infections of various organ systems such as pneumonia, tracheobronchitis, urocystitis, pyelonephritis, Candida oesophagitis and enteritis were found.

Herpetic tracheobronchitis and pneumonia occur basically in immunodepressed patients, but have rarely been reported in patients with the acquired immunodeficiency syndrome (AIDS). Some large reviews on pulmonary manifestations in AIDS report a small number of herpetic pulmonary infections, without determining any prevalence of this particular viral involvement. Predisposing factors are alteration of cell-mediated immunity and invasive procedures (such as endotracheal tube use) in debilitated patients. The case we report illustrates the occurrence of a herpetic tracheitis in an HIV-infected patient with severe P. carinii pneumonia, needing systemic corticotherapy and mechanical ventilation. It illustrates the risk of dissemination of herpes simplex virus (HSV) from a herpetic stomatitis to the lower respiratory tract, even after the endotracheal cannula has been removed.

Microsporidia are ubiquitous in nature. Several clinical syndromes have been associated with microsporidiosis, especially in HIV-infected individuals, and include enteropathy, keratoconjunctivitis, sinusitis, tracheobronchitis, encephalitis, interstitial nephritis, hepatitis, cholecystitis, osteomyelitis, and myositis. Diarrhea and malabsorption are the most common clinical problems. Enterocytozoon bieneusi is the most common microsporidial cause of intestinal disease. A second species, Encephalitozoon intestinalis (originally named Septata intestinalis) is associated with disseminated as well as intestinal disease. Microsporidiosis has been seen worldwide, and is recognized as a frequent enteric infection in patients with AIDS. The pathogenesis of intestinal disease is related to excess death of enterocytes as a result of cellular infection. Clinically, microsporidiosis most often presents with diarrhea and weight loss as a result of small intestinal injury and malabsorption. However, microsporidia have been detected in virtually all organs, and may provoke symptoms related to their specific localization. The diagnosis of microsporidiosis is made histologically, either from tissue biopsies or secretions. While transmission electron microscopy was required for diagnosis in the past, special stains and light microscopy, as well as immunohistochemical and molecular techniques are capable of providing a firm diagnosis. Therapeutic options are limited. Enc. intestinalis responds well to albendazole, while no antiparasitic therapy has documented efficacy in Ent. bieneusi infections.

Although antimicrobial therapy has been administered through the inhaled route for decades, it has always been controversial. There are relatively few accepted indications for this mode of administration. Well-controlled studies of aerosolized antibiotics in cystic fibrosis demonstrate that tobramycin on a cyclical basis may reduce sputum volume, bacterial counts, and improve pulmonary function. Preliminary data indicate that inhaled antibiotic therapy of ventilator-associated tracheobronchitis may reduce sputum volume, but the clinical significance of this finding remains to be determined. Inhaled pentamidine is used for prophylaxis of Pneumocystis carinii in patients with human immunodeficiency virus infection who are intolerant of oral prophylactic agents. Ribavirin has been used for 30 years to treat respiratory syncytial virus. The role, if any, of inhaled antifungal therapy with amphotericin B remains undetermined.

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.

Encephalitozoon hellem is a unicellular, obligate intracellular microsporidian species detected and isolated in HIV-infected patients presenting with keratoconjunctivitis, sinusitis, tracheobronchitis, nephritis, cystitis, and disseminated infection. A total of 24 monoclonal antibodies were produced against E. hellem and characterized. The monoclonal antibodies were of the immunoglobulin (Ig) G and Ig M subclasses, and, when incorporated into indirect immunofluorescence and immunoblotting assays, reacted against 13 isolates of E. hellem originating from three geographic regions. These monoclonal antibodies did not react with one strain each of either Encephalitozoon intestinalis or Encephalitozoon cuniculi, demonstrating their specificity. Two monoclonal antibodies reacted with all karyotype B-E. hellem isolates but did not react with karyotype A-isolates from North America and the Netherlands, thus demonstrating antigenic diversity among E. hellem isolates. These results add to the increasing evidence for diversity among E. hellem, which therefore may be reclassified into subspecies.

Bordetella (B.) bronchiseptica is primarily a zoonotic pathogen, which is often found in upper respiratory tract of various domestic and wild animals. Human infections are rarely reported in immunocompromised patients and are associated with a wide spectrum of presentation ranging from mild cough, tracheobronchitis to sepsis and death. Here, we describe a case of B. bronchiseptica pneumonia that led to the diagnosis of human immunodeficiency virus infection. The diagnosis of B. bronchiseptica infection can be challenging, as there are no distinctive imaging features. This infection mimics Pneumocystis jiroveci infection and unless a detailed evaluation of an unusual presentation is done it may be missed, resulting in increased morbidity and mortality. This case emphasizes the importance of a systematic detailed investigation of patients with unusual pneumonia presentations.
