Abstract
BACKGROUND Cryptococcosis is a fungal infection caused by the yeast-like encapsulated basidiomycetous fungus of the Cryptococcus neoformans (C. neoformans) species complex. These fungi are ubiquitous in soil and bird droppings, and infection by them is an important global health concern, particularly in immunosuppressed patients, such as organ transplant recipients and those infected by the human immunodeficiency virus. The fungus usually enters the body through the respiratory tract, but extremely rare cases of infection acquired by transplantation of solid organs have been reported.
CASE SUMMARY We report a case of disseminated cryptococcosis in a liver transplant recipient, diagnosed 2 wk after the procedure. The patient initially presented with fever, hyponatremia and elevated transaminase levels, manifesting intense headache after a few days. Blood cultures were positive for C. neoformans. Liver biopsy showed numerous fungal elements surrounded by gelatinous matrix and sparse granulomatous formations. Magnetic resonance imaging of the brain showed multiple small lesions with low signal in T2, peripheric enhancement and edematous halo, diffuse through the parenchyma but more concentrated in the subcortical regions. Treatment with amphotericin B for 3 wk, followed by maintenance therapy with fluconazole, led to complete resolution of the symptoms. The recipients of both kidneys from the same donor also developed disseminated cryptococcosis, confirming the transplant as the source of infection. The organ donor lived in a rural area, surrounded by tropical rainforest, and had negative blood cultures prior to organ procurement.
CONCLUSION This case highlights the risk of transmission of fungal diseases, specifically of C. neoformans, through liver graft during liver transplantation.

Abstract
Immunosuppression after solid-organ transplantation can lead to opportunistic infections as cryptococcosis. A 69-year-old female, cadaveric renal-transplant recipient, manifested with ulcerative lesions on the 7th month of immunosuppression. Histological examination confirmed the diagnosis of cryptococcosis. Treatment with systemic and topical antifungal therapy for 7 months concluded in significant cutaneous improvement. This case presentation encourages high clinical suspicion of opportunistic pathogens such as Cryptococcus spp. and highlights the necessity of appropriate management.

Abstract
Genotypic diversity and fluconazole susceptibility of 82 Cryptococcus neoformans and Cryptococcus gattii isolates from 60 renal transplant recipients in Brazil were characterized. Clinical characteristics of the patients and prognostic factors were analysed. Seventy-two (87.8%) isolates were C. neoformans and 10 (12.2%) were C. gattii. VNI was the most common molecular type (40 cases; 66.7%), followed by VNII (9 cases; 15%), VGII (6 cases; 10%), VNB (4 cases; 6.7%) and VNI/II (1 case; 1.7%). The isolates showed a high genetic diversity in the haplotype network and six new sequence types were described, most of them for VNB. There was a bias towards skin involvement in the non-VNI population (P = .012). VGII isolates exhibited higher fluconazole minimum inhibitory concentrations compared to C. neoformans isolates (P = 0.008). The 30-day mortality rate was 38.3%, and it was significantly associated with fungemia and absence of headache. Patients infected with VGII had a high mortality rate at 90 days (66.7%). A variety of molecular types produce disease in renal transplant recipients in Brazil and highlighted by VGII and VNB. We report the clinical appearance and impact of the molecular type, fluconazole susceptibility of the isolates, and clinical characteristics on patient outcome in this population.

Abstract
OBJECTIVE Infections play an important part in post-transplantation causes of morbidity and mortality. The purpose of this study is to evaluate short-, and long-term infections encountered in after renal transplantations. MATERIAL AND METHODS Two hundred and thirteen cases that consisted of both living and cadaver donors, who suffered from late period renal insufficiency and had renal transplant between June 2011 and January 2016 at the Transplantation Center of Sanko University School of Medicine were included in the study. In this study the short-, and long-term infections seen in post renal transplantation were examined retrospectively. Infection types, frequency and periods of infection, infection agents and predisposing factors were determined as the examination parameters. RESULTS Of the 213 patients who received renal transplant, 139 were males (65.3%) and 74 were women (34.75%) and the mean age was 42±11,8 (range, 14-70) years. Twelve (5.6%) patients exited after renal transplantation. Post-transplant infections were seen in 49 patients (23.1%) within 1-6 months; in 13 patients (6.1%) within 6-12 months; and in 5 patients (2.4%) after the 12th month. The most common infections after renal transplantation were associated with urinary tract (70 patients, 34.3%). The most frequently isolated agents were E. coli (n=66; 30.9%), Kebsiella spp. (n=18; 8.4%) and Enterococci (n=18; 8.4%) respectively. The renal transplants from the cadavers were observed to contract infections 1.78 times more frequently compared to the living donors (OR=1.78, 95% CI=1.03-3.09). CONCLUSION The most common complication after renal transplantation are infections. The majority of the infections are seen within the first year especially between 1-6 months. Post-transplant infections are often related to urinary system. E.coli is the most frequently isolated agent and it may be responsible for urosepsis in renal transplant patients. Infection more often seen in renal transplantations from cadavers.

Abstract
Cryptococcal infection has been documented in 2.8% of solid-organ transplant recipients, with the median time to disease onset being 21 months. Renal transplantrecipients accountforthe majority of cases. Most patients present with central nervous system or disseminated disease, with only a minority having cutaneous manifestations. We present the case of a 47-year-old female renal transplant recipient who presented with refractory acute cellulitis 7 months after transplant. She had received thymoglobulin induction and was on a maintenance immunosuppressive regimen oftacrolimus, mycophenolic acid, and prednisone (5 mg/d). She did not respond to broad-spectrum antibacterial therapy for presumed bacterial cellulitis. Skin and soft tissue biopsies subsequently showed the presence of yeast; Cryptococcus neoformans was recovered in culture. Blood cultures, chest radiography, and cerebrospinal fluid sampling were negative, which resulted in a diagnosis of multifocal soft tissue cryptococcosis, a form of disseminated disease. Serum cryptococcal antigen testing was strongly positive (≥ 1:2560). The patient's immunosuppression was reduced, and she received treatment with liposomal-amphotericin B and flucytosine for 2 weeks, which resulted in symptomatic improvement. This was followed by 1 year of consolidation and subsequent maintenance therapy with fluconazole. This case should increase awareness of the broader differential diagnosis of soft tissue infection in immunocompromised patients. Her case mimicked bacterial cellulitis, which delayed administration of effective therapy. Although our patient was initially diagnosed via biopsy, early clinical suspicion and serum cryptococcal antigen testing can lead to the correct diagnosis more rapidly. As transplant patients return to their community providers, heightened vigilance for unusual infections and presentations is warranted.The possibility of a cryptococcal cause for acute soft tissue infection should be considered, even in the absence of pulmonary or central nervous system involvement.
