Renal aspergillosis is an extremely uncommon complication in HIV-infected patients. In general, prognosis is poor and the need for nephrectomy is emphasized. We report the case of a 37-year-old patient with AIDS since April 2003 (CD4 count 10 cells/mm(3), a high viral load, Candida esophagitis, bilateral pneumonia, HIV encephalopathy). Treatment with zidovudine, lamivudine, nevirapine, and lopinavir/ritonavir was started. Adherence to this medication proved to be a problem, but after 18 weeks of HAART the CD4 count was 110 cells/mm(3) and viral load was undetectable. One year later, he presented with hematuria and flank pain. Computed tomography (CT) scan revealed multiple lesions in both kidneys. Cultures of the abscess aspirates yielded Aspergillus fumigatus. Our review of 18 reported cases shows that prognosis of renal aspergillosis is poor if nephrectomy is not performed. However, in the present case a conservative approach was chosen to avoid life-long dialysis. The patient was treated successfully with a combination of voriconazole, percutaneous drainage, and highly active antiretroviral therapy (HAART). Renal function was completely preserved. Reported cases from the literature of renal aspergillosis in HIV-infected patients are summarized in this paper.

In immunosuppressed individuals, such as hematopoietic stem cell transplant recipients, adenoviruses (ADVs) are a well-known cause of morbidity and mortality, with limited treatment options. However, only a few cases were reported in patients with acquired immunodeficiency syndrome (AIDS), and little is known about the relevance of such an infection in these patients with many other concomitant opportunistic infections. We report the case of a 34-year-old man with AIDS presenting with gross hematuria, right flank pain, and acute decrease in kidney function superimposed on chronic kidney disease. His CD4 count was 0/muL despite highly active antiretroviral therapy. A computed tomographic scan showed enlargement of the right renal pelvis. Cystoscopy showed no clots or macroscopic lesions. Urine analysis showed no bacteria or abnormal epithelial cells. ADV was found in viral culture and by using real-time polymerase chain reaction in the patient's urine and later in blood. The renal biopsy specimen showed ADV-related tubulointerstitial nephritis with intranuclear inclusions in tubular cells stained by anti-ADV antibodies, in addition to chronic tubular and vascular changes. The ADV serotype belonged to subgroup B. Cidofovir therapy was contraindicated for this patient; therefore, he was administered intravenous ribavirin. The efficiency of this treatment could not be assessed because he rapidly developed neutropenia and disseminated aspergillosis and died. This case illustrates another cause of acute kidney disease in very immunosuppressed patients with AIDS, probably underdiagnosed.

BACKGROUND Leiomyosarcoma is the most common primary malignancy of the inferior vena cava (IVC), and represents approximately 10% of primary retroperitoneal sarcomas. Leiomyosarcoma presents with non-specific symptoms, including abdominal pain or back pain. There is an increased incidence in immunosuppressed individuals. CASE REPORT An unusual presentation of IVC leiomyosarcoma is reported in a 46-year-old female patient infected with human immunodeficiency virus (HIV) who was on highly active antiretroviral therapy (HAART) and who had a normal CD4 count of 934, who presented with back pain. Magnetic resonance imaging (MRI) of the lumbar spine showed a mass of the IVC. Initial computed tomography (CT)-guided biopsy of the IVC mass was non-diagnostic. An IVC filter was inserted, and the patient was discharged home, but 20 days later, she returned to the hospital with worsening right flank pain. Laboratory tests showed acute renal failure, and a repeat CT scan showed IVC thrombus extending 5 cm superiorly. When compared with the previous CT, there was an extension of thrombus into both renal veins. Histopathology of a transjugular needle core biopsy showed a moderately differentiated leiomyosarcoma. The patient was transferred to a multidisciplinary sarcoma center for surgical resection, chemotherapy, and radiation therapy. CONCLUSIONS This report is of a rare case of IVC leiomyosarcoma in a middle-aged HIV-positive woman with a normal CD4 count. Leiomyosarcoma of the IVC is extremely rare, is often detected when advanced, and has a poor prognosis. This case report describes the clinical, imaging, surgical and histopathological findings of leiomyosarcoma of the IVC.
