Adenovirus-induced haemorrhagic cystitis has been reported chiefly in bone marrow or kidney transplant recipients. We report here on an HIV-positive patient treated for a Burkitt's lymphoma who developed gross haematuria associated with fever and burning urination. Usual causes of haematuria were ruled out: lithiasis, urinary tract lesions, glomerulonephritis, mycobacterium and schistosoma infections, and drug toxicity. Adenovirus was detected by cellular cultures and BK/JC virus DNA sequences were detected using a polymerase chain reaction method. Because BK/JC virus shedding is very common (75%) in HIV patients receiving chemotherapy, our data strongly suggest that adenovirus was responsible for the haemorrhagic cystitis in our patient. In conclusion, adenovirus should be considered as a potential cause of haemorrhagic cystitis in AIDS patients whose immunosuppression is aggravated by cytotoxic drugs.
We examined the relationship between the profile of HIV-specific T helper (Th) cell responses, cytotoxic T lymphocyte (CTL) activity, HIV viral load, and CD4(+) T cell counts during longitudinal studies in children with perinatal HIV infection. Patients with AIDS demonstrated undetectable or low levels of HIV-specific Th and CTL activities, and exhibited almost exclusively Th0 type of responses with low IFN-gamma and IL-4 production. The levels of IL-2 expression in the envelope (env) peptide-stimulated peripheral blood mononuclear cells were increased in children with a slowly progressive disease, concomitant with higher numbers of CD45RO(+) memory T cells and increased proportions of Th1 clones. In these patients, high levels of env peptide-specific IL-2 expression correlated with increases in HIV-specific CTL responses, whereas a delay in the generation of HIV-specific CTL activity was associated with lower IL-2 production and elevated Th2 responses. Patients with slow disease progression produced higher levels of beta-chemokines than those detected in children with AIDS. These results suggest that an impaired development of HIV-specific cellular responses and inhibition of T cell differentiation during infancy are associated with fast disease progression. They also point to a protective role of noncytotoxic antiviral activity that might complement HIV-specific CTL responses in children with a slowly progressive disease.
