Choriocarcinoma transmitted with the transplant: Case study.

Choriocarcinoma is a rare kind of cancer, which may be either gestational or non-gestational. Choriocarcinoma is responsible for about a quarter of all documented neoplastic aneurysms. It is a descriptive case report of choriocarcinoma transmission from a donor, following kidney donation. A 45-year-old woman got a kidney from a 25-year-old woman who was taken to the hospital due to a non-traumatic cerebral hemorrhage. She delivered a healthy baby 48 days before her brain death. The transplant was successfully done. Five weeks' post-transplantation, the recipient had pain and erythema in the surgical area. Regarding the high level of beta-human chorionic gonadotropin in her blood, diagnostic tests were performed. Following the confirmation of the cancer, a five-phase chemotherapy plan with various pharmaceutical regimens was initiated. Liver function test values rose after the final round of chemotherapy, and the patient developed hepatic encephalopathy. Considering the thrombocytopenia, dialysis, or hemoperfusion, which are normally performed to reduce liver enzymes, were not initiated. Finally, she died due to the hepatic failure and disseminated intravascular coagulation. Although the nephrologists disagree on the optimal course of treatment, it seems that nephrectomy would be helpful in such instances. Physicians should be aware of the possibility of transplant-related choriocarcinoma in female donors of reproductive age who die because of intracerebral brain hemorrhage for unclear reasons. Every donor must undergo a thorough examination. It is critical to get documents, clarify history, and interview relatives.

COVID-19 Infection in Kidney Transplant Recipients From a Single Center in Iran.

OBJECTIVES: COVID-19 has been spreading rapidly throughout the world, with nearly every country thus far documenting this infection. In this study, our aim was to evaluate the risk factors for increased mortality in deceased donor kidney transplant recipients with COVID-19 at a single center in Iran. MATERIALS AND METHODS: This was a retrospective study in a single center. During the 17-month ongoing COVID19 pandemic in Iran, there were 153 deceased donor kidney recipients at our center with suspected COVID19 symptoms. Of these patients, 138 had positive COVID-19 tests, and thus a therapeutic regimen was commenced for these patients. Data were analyzed with SPSS version 16 software. RESULTS: The patients were predominantly male (83, 60.1%) with a median age of 47.09 ± 13.75 years and a median time since transplant of 51 months (IQR, 1-276 months). Among these patients, 84 (60.8%) had hypertension and 43 (31.2%) had diabetes mellitus. We observed a significant relationship between disease severity and mortality (P < .001). After risk adjustments for age, presence of diabetes mellitus and hypertension and blood group type were factors that showed a significantly higher risk of death. CONCLUSIONS: Deceased donor kidney transplant recipients with confirmed COVID-19 experienced less fever as an initial symptom. However, recipients with COVID-19 and an underlying disease had a higher rate of mortality, severity of infection, and progression of disease. Appropriate management of renal complications and vaccinations in deceased donor kidney transplant recipients may help lead to more favorable outcomes.

Posttransplant infectious complications: a prospective study on 142 kidney allograft recipients.

INTRODUCTION: We evaluated the posttransplant complications resulting from infections and their association with graft function, immunosuppressive drugs, and mortality. MATERIALS AND METHODS: A total of 142 kidney allograft recipients were followed for 1 year after transplantation. The patients' status was assessed during regular visits, and data including clinical characteristics, infections, serum creatinine level, acute rejection episodes, immunosuppressive regimen, graft function, and mortality were recorded and analyzed. RESULTS: Infections occurred in 77 patients (54%). The lower urinary (42%) and respiratory (6.3%) tracts were the most common sites of infection. The most frequent causative organisms were Klebsiella in 34 (24%) and cytomegalovirus in 25 patients (18%). Wound infection occurred in 7 patients (5%). The mortality rate was 7.7% and infection-related death was seen in 5 patients (3.5%) who developed sepsis. Graft loss was seen in 16 patients (11%), of whom 2 developed cytomegalovirus infection, 2 experienced urinary tract infection, and 5 developed sepsis and died. Mycobacterial and hepatitis C infections were noticeably rare (0.7% and 2.8%, respectively). CONCLUSION: This study showed that infections are important causes of morbidity and mortality during the posttransplant period. We recommend that serologic tests be performed before and after transplantation to recognize and meticulously follow those who are at risk. In our study, high-risk patients were those with elevated serum creatinine levels who received high doses of immunosuppressive drugs. As the urinary tract is the most common site of infection, early removal of urethral catheter is recommended to reduce the risk of infection.
