Disseminated adenovirus disease in heart transplant recipient presenting with conjunctivitis.

We report a 65-year-old heart transplant recipient who presented with conjunctivitis, likely acquired from a family member who worked at a daycare center during an outbreak of conjunctivitis. He developed a severe adenoviral pneumonitis, which was successfully treated with intravenous cidofovir combined with a reduction of immunosuppression.

Chronic kidney disease and end-stage renal disease are risk factors for poor outcomes of Clostridium difficile infection: a systematic review and meta-analysis.

BACKGROUND: The objective of this systematic review and meta-analysis was to assess the clinical outcomes of Clostridium difficile infection (CDI) in patients with chronic kidney diseases (CKD) and end-stage renal disease (ESRD). METHODS: A literature search was performed from inception through February 2015. Studies that reported relative risks, odds ratios or hazard ratios comparing the clinical outcomes of CDI in patients with CKD or ESRD and those without CKD or ESRD were included. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random-effect, generic inverse variance method. RESULTS: Nineteen studies (a case-control and 18 cohort studies) with 116,875 patients assessing clinical outcomes of CDI were included in the meta-analysis. Pooled RR of severe or complicated CDI in CKD patients was 1.51 (95% CI: 1.00-2.28). The risk of recurrent CDI is significant higher in patients with a pooled RR of 2.73 (95% CI: 1.36-5.47). The pooled RR of mortality risk of CDI in patients with CKD, ESRD and CKD or ESRD were 1.76 (95% CI: 1.26-2.47), 1.58 (1.37-1.83) and 1.76 (1.32-2.34) respectively. CONCLUSION: This meta-analysis demonstrates poor outcomes of CDI including severe and recurrent CDI in CKD patients. History of CKD and ESRD are both associated with increased mortality risk in patients with CDI.

Epidemiology and Outcome of Ganciclovir-Resistant Cytomegalovirus Infection After Solid Organ Transplantation: A Single Transplant Center Experience in Thailand.

BACKGROUND: Data on drug-resistant cytomegalovirus (CMV) infection in solid organ transplantation (SOT) are not often reported from resource-limited settings. We aimed to investigate the epidemiology and outcomes of this infection in SOT recipients at our institution. METHODS: This was a retrospective study conducted from January 2012 to May 2015. We included all SOT recipients who were suspected for drug-resistant CMV infection. Genotypic assay for UL97 gene mutation was analyzed by real-time polymerase chain reaction. Patients were reviewed for demographic data, clinical presentation, virologic data, treatment, and outcomes. RESULTS: The population consisted of 18 (12 kidney, 6 liver) SOT recipients with a median age of 20 years (interquartile range [IQR], 1-49); 44% were male. Anti-CMV resistance testing was analyzed at a median time of 23 days (IQR, 14-33) after initiation of anti-CMV therapy with a median CMV load of log 3.79 copies/mL (IQR, 3.37-4.58). During a median period of 2 years (IQR, 1-3), 6 SOT recipients were identified with UL97 gene mutation in codon 460, conferring ganciclovir (GCV) resistance. Patients with UL97 gene mutation had a longer mean duration of CMV DNAemia compared with those without mutation (263 vs 107 days; P = .04). All patients received high-dose GCV. Two patients received foscarnet and cidofovir. Two patients died (non-CMV-related), and 4 patients developed opportunistic infections other than CMV. CONCLUSIONS: GCV-resistant CMV infection in SOT recipients is an emerging clinical problem in resource-limited country. Those with UL97 mutation CMV infection have prolonged duration of CMV DNAemia. Clinicians should be aware of this condition when caring for SOT recipients.
