There is an increasing concern about HIV infection in paediatric age, due to its increasing incidence in some countries, especially in Europe, and due to its social aspects. HIV infection has particular features, while occurring during paediatric age: infection of child frequently occurs during pregnancy (perinatal form of HIV infection), a period characterized by the immaturity of the immune system of the host. Encephalopathy is a frequent manifestation of the disease, recurrent fever episodes have a different pathogenesis than in adults, LIP (lymphocytic interstitial pneumonia) is a common manifestation of the disease and there is a higher progression rate to AIDS. Antiretroviral therapy, as zidovudine (AZT) in paediatric age is still on clinical trials, and only few preliminary data are available.

Recently we encountered a case of pulmonary tuberculosis with HIV infection. The patient was 54-years old male. His chief complaints were anemia, emaciation and severe diarrhea. He was admitted to our hospital on September 18, 1992. He had been diagnosed in another clinic as having pulmonary tuberculosis before the admission to our hospital. His chest films taken on admission revealed homogeneous infiltrates with cavitation in right upper lobe. Serial chest X-rays consisted with the findings of post-primary tuberculosis. Sputum smear for acid fast bacilli was positive. From his clinical manifestations and life-history, we had a suspicion that he had infected with HIV. Laboratory findings were as follows: serum albumin level was 1.9 g/dl, CRP was 10.2 mg/dl, serological tests for HIV were positive by EIA, IFA and western blott method, total lymphocyte count was 819/microliters, CD4+ T lymphocyte count was 120/microliter CD4+/CD8+ ratio was 0.2. He was treated with AZT, isoniazid, streptomycin and rifampicin. The disease progressed rapidly and interstitial pneumonia, jaundice and clouding of consciousness appeared at the terminal stage. He expired on October 14, 1992. In this paper, the authors reported a case of pulmonary tuberculosis with HIV infection and also reviewed 5 cases of pulmonary tuberculosis associated with HIV in Japan.

One of the major complications of HIV infection is the development of interstitial pneumonitis (IP). IP is characterized by lymphocytic infiltration of the lung and may lead to respiratory failure in some cases. The etiology of IP is unknown although it is likely the result of an antiviral or autoimmune response occurring in the lung. To determine the role of viral replication in the development of IP, AZT was evaluated for the ability to inhibit development of lung inflammation in a murine model of retrovirus-associated IP. Mice were infected with LP-BM5 retrovirus, which induces murine AIDS. Infected mice develop IP by 4 weeks postinfection characterized by infiltration of the lung with activated T cells, B cells, and macrophages. Virus could be detected in the lungs of these mice by 2 weeks postinfection and persisted throughout the course of disease. To determine if reduction in viral load affected the disease process, infected mice were treated with AZT for varying periods postinfection and analyzed for the development of IP. Treatment with AZT resulted in a treatment time-dependent reduction of viral RNA in the lungs of infected mice compared to untreated infected mice. The reduction of viral burden in the lungs correlated with a reduction in the severity of IP and decreased production of the proinflammatory cytokines interleukin (IL)-1 beta and interferon (IFN)-gamma. These results suggest that continuous viral replication in the lung contributes to the pathogenesis of IP.
