Unrecognized pretransplant and donor­derived cryptococcal disease in organ transplant recipients.

BACKGROUND: Cryptococcosis occurring ≤30 days after transplantation is an unusual event, and its characteristics are not known. METHODS: Patients included 175 solid-organ transplant (SOT) recipients with cryptococcosis in a multicenter cohort. Very early-onset and late-onset cryptococcosis were defined as disease occurring ≤30 days or >30 days after transplantation, respectively. RESULTS: Very early-onset disease developed in 9 (5%) of the 175 patients at a mean of 5.7 days after transplantation. Overall, 55.6% (5 of 9) of the patients with very early-onset disease versus 25.9% (43 of 166) of the patients with late-onset disease were liver transplant recipients (P = .05). Very early cases were more likely to present with disease at unusual locations, including transplanted allograft and surgical fossa/site infections (55.6% vs 7.2%; P < .001). Two very early cases with onset on day 1 after transplantation (in a liver transplant recipient with Cryptococcus isolated from the lung and a heart transplant recipient with fungemia) likely were the result of undetected pretransplant disease. An additional 5 cases involving the allograft or surgical sites were likely the result of donor‐acquired infection. CONCLUSIONS: A subset of SOT recipients with cryptococcosis present very early after transplantation with disease that appears to occur preferentially in liver transplant recipients and involves unusual sites, such as the transplanted organ or the surgical site. These patients may have unrecognized pretransplant or donor-derived cryptococcosis.

Cutaneous cryptococcosis in solid organ transplant recipients.

Clinical manifestations, treatment, and outcomes of cutaneous cryptococcosis in solid organ transplant (SOT) recipients are not fully defined. In a prospective cohort comprising 146 SOT recipients with cryptococcosis, we describe the presentation, antifungal therapy, and outcome of cutaneous cryptococcal disease. Cutaneous cryptococcosis was documented in 26/146 (17.8%) of the patients and manifested as nodular/mass (34.8%), maculopapule (30.4%), ulcer/pustule/abscess (30.4%), and cellulitis (30.4%) with 65.2% of the skin lesions occurred in the lower extremities. Localized disease developed in 30.8% (8/26), and disseminated disease in 69.2% (18/26) with involvement of the central nervous system (88.9%, 16/18), lung (33.3%, 6/18), or fungemia (55.6%, 10/18). Fluconazole (37.5%) was employed most often for localized and lipid formulations of amphotericin B (61.1%) for disseminated disease. Overall mortality at 90 days was 15.4% (4/26) with 16.7% in disseminated and 12.5% in localized disease (P = 0.78). SOT recipients who died were more likely to have renal failure (75.0% vs. 13.6%, P = 0.028), longer time to onset of disease after transplantation (87.5 vs. 22.6 months, P = 0.023), and abnormal mental status (75% vs. 13.6%, P = 0.028) than those who survived. Cutaneous cryptococcosis represents disseminated disease in most SOT recipients and preferentially involves the extremities. Outcomes with appropriate management were comparable between SOT recipients with localized and disseminated cryptococcosis.

Geographic differences in disease expression of cryptococcosis in solid organ transplant recipients in the United States.

BACKGROUND: Whether there are geographic differences in clinical presentation of cryptococcosis in solid organ transplant (SOT) recipients in the United States (US) is not known. MATERIAL/METHODS: Patients comprised a cohort of 120 SOT recipients from US transplant centers who fulfilled the EORTC/MSG criteria for cryptococcal disease. RESULTS: Central nervous system, pulmonary, and cutaneous cryptococcal disease were observed in 51% (61/120), 64% (77/120), and 15% (18/120) of the patients, respectively. Cutaneous disease was documented in 9% (3/32) of the patients from South Atlantic region, 19% (6/32) from Mid Atlantic, 26% (6/23) from Southern, 7% (2/29) from Midwestern, and in 1 of 4 patients from the Northwestern region of the US. When controlled for age, immunosuppressive regimen, type of transplant, and renal failure at baseline, patients from the Southern compared with other regions of the US were significantly more likely to have cutaneous cryptococcal disease (OR 3.8, 95% CI 1.1-14, P=0.045). CONCLUSIONS: Post-transplant cryptococcosis is more likely to present with cutaneous disease in the Southern region compared with other regions in the US. This predilection for cutaneous cryptococcosis could not be explained on the basis of differences in immunosuppression or the type of transplant. Whether our findings are related to strain-related variations in characteristics of the yeast or other transplant variables remains to be determined.

Anxiety and depression in hospitalized patients in resistant organism isolation.

BACKGROUND: Previous studies have reported an increase in psychiatric symptoms in seriously ill patients who were placed in resistant organism isolation. We conducted this study to assess whether there is an increase in symptoms of anxiety and depression in patients who are not critically ill and are placed in isolation. METHODS: Patients hospitalized with methicillin-resistant Staphylococcus aureus or vancomycin-resistant Enterococcus species infections were evaluated with the Hamilton Anxiety Rating Scale and the Hamilton Depression Rating Scale at baseline and again during hospitalization. The results were then compared with the results of patients who were hospitalized for infectious diseases that did not require isolation. RESULTS: Patients in isolation had significantly higher scores on both the anxiety and depression scales at the time of follow-up than did patients who were not isolated. There was no significant difference between the scores of the two groups before isolation. CONCLUSION: The results of this preliminary study suggest that placement in resistant organism isolation may increase hospitalized patients' levels of anxiety and depression.
