Impact of syphilis infection on HIV viral load and CD4 cell counts in HIV-infected patients.

OBJECTIVES: To assess the effect of early syphilis on HIV viral load (VL) and CD4 cell count in patients with HIV and to analyze factors associated with changes in HIV VL and CD4 cell count. DESIGN: Multicenter study of a series of patients with HIV who were diagnosed with early syphilis infection during 2004 through 2005. Patients who started or changed their highly active antiretroviral therapy (HAART) regimen during the analysis period were excluded. RESULTS: One hundred eighteen patients were analyzed: 95.8% were men, mean patient age was 38.2 years, 83.9% were homosexual men, 50.8% were on antiretroviral therapy at the time syphilis was diagnosed, and HIV and syphilis diagnoses were coincident in 38 (32.2%) cases. CD4 cell counts were lower during syphilis than before (590 vs. 496 cells/microL; P = 0.0001) and after syphilis treatment (509 vs. 597 cells/microL; P = 0.0001). The HIV VL increased in 27.6% of patients during syphilis. The only factor associated with an HIV VL increase was not being on HAART, and the only factor associated with a CD4 count decrease >100 cells/microL during syphilis was the prior CD4 cell count. CONCLUSIONS: Syphilis infection was associated with a decrease in the CD4 cell count and an increase in the HIV VL in almost one third of the patients. In this series, more than two thirds of the syphilis cases were diagnosed in patients who were previously known to be infected with HIV.

Pleural aspergillosis with bronchopleurocutaneous fistula and costal bone destruction: a case report.

A 65-year-old man who, when young, had had tuberculosis treated by therapeutic pneumothorax, consulted his family physician for a constitutional syndrome and dyspnea. At this time radiologic studies showed left pleural effusion with bilateral calcified plaques, an infiltrate in the upper left lobe, and a picture compatible with aspergilloma, all suggesting semi-invasive aspergillosis. The patient failed to show up for his followup visit, so no therapy could be started or further diagnostic tests ordered. One month later he was admitted to this hospital for a bronchopleural fistula (empyema necessitatis) with subsequent spontaneous hydropneumothorax and costal bone involvement. The patient underwent surgery because of his rapid worsening condition. Biopsy examination revealed a large pleural aspergilloma. Despite immediate antifungal therapy, the patient died. We believe this to be the first report of pleural Aspergillus with a bronchopleurocutaneous fistula and costal bone destruction.
