Abstract Objective.—To describe one case of symptomatic skin and pleural Kaposi sarcoma (KS) associated with kidney transplantation. Diagnosis was supported by morphologic study and human herpesvirus 8 (HHV-8) detection in both tissues. Pulmonary involvement was not present. Design.—The presence of HHV-8 DNA sequences was proved using polymerase chain reaction (PCR), Southern blot hybridization, and in situ hybridization. Setting.—Human herpesvirus 8 is found in most KS from patients with and without the acquired immunodeficiency syndrome. Clinically significant pulmonary infiltration by KS is diagnosed uncommonly antemortem, and pleural disease is exceptional. Patient.—A 49-year-old man who had renal transplant with immunosuppressive therapy (tacrolimus and prednisone) and developed a cutaneous KS. A pleural effusion appeared without pulmonary involvement. Both lesions disappeared when immunosuppressive drugs were suspended. Later, the pleural effusion and the cutaneous lesions reappeared. Pleural biopsy specimens showed KS infiltration. Outcome.—The patient refused treatment and was lost to follow-up. Results.—The skin and pleural biopsies showed a proliferation of spindle-shaped cells positive for CD34. The HHV-8 sequences were detected by nested PCR. No amplification was detected in uninvolved skin from the patient or in peripheral blood mononuclear cells from 10 healthy individuals used as controls. The Southern blot hybridization confirmed these results. Conclusions.—To our knowledge, this is the first report of HHV-8 in symptomatic pleural KS, which was probably associated with immunosuppression after kidney transplantation. The demonstration of HHV-8 DNA in biopsy material in the appropriate cells could be diagnostic when the morphologic setting is consistent with KS.

Clinically Significant

Abstract The identification of Nocardia transvalensis, an unusual and probably underrecognized cause of nocardial infection, is clinically significant because of this species' resistance to aminoglycosides, a standard antinocardial therapy. Diagnosis requires analytic methods available predominately in reference laboratories. We report a case of disseminated infection with N transvalensis with primary pulmonary involvement and subsequent development of brain abscesses, and review the literature to date. Familiarity with the epidemiology, pathologic findings, and clinical significance of this and other unusual Nocardia species may increase early identification and antibiotic susceptibility testing in cases of nocardial infection.

The Difference

High HHV-8 viral load (VL) in Kaposi Sarcoma (KS) has been associated with severe Immune reconstitution inflammatory syndrome (S-IRIS-KS), which can occur after initiating cART, and is linked with high mortality particularly in patients with pulmonary involvement. We investigate if valganciclovir initiated before cART decreases HHV-8 VL and assess if it reduces the incidence of S-IRIS-KS and its attributable mortality. Methods: Open-label parallel-group randomized clinical trial in AIDS cART naive patients with disseminated KS (DKS) as defined by at least two of the following: pulmonary, lymph-node or gastrointestinal involvement, lymphedema, or equal or more 30 skin lesions. In the experimental group (EG), patients were randomized to valganciclovir 900 mg BID four weeks before cART and continued until week-48; in the control group (CG), cART was initiated on week-0. Non-severe-IRIS-KS was defined as: increase in the number of lesions plus equal or more than one log10 HIV-VL decrease or equal or more than 50 cells/mm3 increase or equal or more than 2-fold rise in baseline CD4+ cells. S-IRIS-KS was defined as abrupt clinical worsening of KS lesions and/or fever after ruling out another infection following cART initiation, and at least three of the following: thrombocytopenia, anemia, hyponatremia, or hypoalbuminemia. Results: 40 patients were randomized and 37 completed the study. In the ITT analysis, the overall mortality did not differ between groups. In the per-protocol analyses, the difference showed a trend for higher S-IRIS-KS mortality in the CG 3/19 (15.7%), compared to EG 0/18 (p=0.07). The incidence of S-IRIS KS was significantly lower in the EG; two patients, one each had S-IRIS-KS episode (0.038 per 100 patient-days) compared to CG group, four patients developed 12 S-IRIS-KS episodes (0.21 per 100 patient-days); incidence rate of 0.09 (95% CI 0.02-0.5 p=0.006). Mortality in patients with pulmonary KS was significantly lower in EG, 3/4 in CG vs 0/5 in EG. S-IRIS-KS was associated with higher HHV-8-VL; IL6 and CRP; valganciclovir was protective. Of survivors at week 48, 82% achieved more than 80% remission. No difference was found between groups in the number of non-S-IRIS-KS events. Conclusions: Valganciclovir significantly reduced the episodes of S-IRIS-KS although attributable KS mortality was lower in the EG the difference was not significant (p=0.07). Mortality was significantly lower in EG patients with pulmonary KS.
