Acute Thyroid Swelling in Renal Transplant Recipient.

Tuberculosis (TB) of thyroid gland is rare entity even in solid organ transplant recipients who have a high risk of TB. Thyroid TB is easily diagnosed by fine needle aspiration cytology. The majority of cases require only antitubercular drugs for treatment, and surgical intervention is required only in few patients. We here describe a case of thyroid TB presenting as an acute abscess in postrenal transplant recipient with a background of acute rejection treated with steroid and antithymocyte globulin.

Successful renal transplantation from a brain-dead deceased donor who died from snakebite: a case report.

Even though India is the country with the highest annual number of deaths (50,000) from snakebite, there is contradictory evidence regarding acceptance of deceased donors (DD) who died from this cause. We present 2 successful renal transplantations (RTx) from a brain-dead DD who died from a neurotoxic snakebite without manifestations of a viper bite. We accepted the donor as he exhibited no evidence of hematoxic snakebite. Rather the findings were consistent with a neurotoxic bite (probably krait), which can cause hypoxic brain injury. Both recipients established good diuresis intraoperatively and did not require hemodialysis. The patients were discharged with good diuresis and normal serum creatinines. After 3-month follow-up, both recipients show normal graft function. According to our experience of favorable RTx outcomes from a brain-dead DD who died from neurotoxic snakebite may expand the donor pool.

Post-renal transplant cytomegalovirus infection: study of risk factors.

OBJECTIVES: Cytomegalovirus (CMV) is a common opportunistic infection following renal transplantation (RTx). It responds promptly to antiviral treatment. The mortality rate reaches 90% if untreated. Identification of risk factors helps in the early diagnosis of CMV. We studied demographic features, risk factors, and outcomes associated with CMV infection in RTx recipients despite ganciclovir prophylaxis. MATERIALS AND METHODS: We reviewed 720 RTx recipients between 2007 and 2009. We examined the serostatus of the donor and recipient before transplantation using an enzyme-linked immunosorbent assay, and diagnosed CMV infections in recipients by CMV DNA detection with a polymerase chain reaction. RESULTS: A total of 42 of 750 (5.6%) patients were identified to display CMV infection (69.1%) or disease (30.9%). Their mean age was 34 ± 13.5 years, with 80.9% men. CMV serologic status was D+/R- in 21.4% and D+/R+ in 59.5% patients. Fever, malaise (76.2%), and leukopenia (52.3%) were the commonest presenting symptoms; diabetes (30.9%) and hepatitis C virus (28.6%) the commonest comorbid conditions. Risk factors were triple drug immunosuppression (47.6%), antithymocyte globulin ATG induction (54.8%), and a rejection episode (26.1%) and methylprednisolone (76.2%) which were more common in CMV disease than infection. Mean CMV DNA at diagnosis was 78,803; 71.2% patients developed CMV within 6 months posttransplantation, the majority occurring after 3 months. With a mean follow-up of 4 ± 1.9 years, patient and graft survival rates were 85.7% and 81% with a mean serum creatinine value of 1.83 ± 12 mg/dL. CONCLUSIONS: Universal CMV prophylaxis was associated with a low incidence (5.6%) and mild form of CMV disease among our patients.

Clinical outcome of renal transplantation in end-stage renal disease patients with positive pretransplantation hepatitis B surface antigen.

BACKGROUND: Renal transplantation (RTx) is the best therapeutic modality for patient suffering from end-stage renal disease (ESRD) with positive pretransplantation hepatitis B surface antigen (HbsAg). We report 11 years of single-center experience on RTx vis-à-vis patient/graft survival, graft function in terms of serum creatinine (SCr), and rejection episodes in 35 ESRD patients with pretransplantation HbsAg positivity. PATIENTS AND METHODS: Thirty-five ESRD patients with pretransplantation HbsAg positivity underwent RTx at our center between 2000 and 2010. Mean recipient age was 36.06 ± 12.22 years; 30 were males and 5 were females. Mean donor age was 43.51 ± 13.63 years; 13 were males and 22 were females. The majority of donors were parents (31.42%) and spouses (22.85%). Mean HLA match was 2 ± 1.37. The most common recipient diseases leading to ESRD were chronic glomerulonephritis (51%) and diabetes (17.5%). Posttransplantation immunosuppression consisted of a calcineurin inhibitor-based regimen. RESULTS: Over mean follow-up of 6.16 ± 3.69 years, patient and graft survival rates were 71.42% and 71.42%, respectively, with mean SCr of 1.92 ± 0.62 mg% with 20% biopsy-proven acute rejection episodes. In total, 10 (28.57%) patients were lost, mainly to infections. CONCLUSION: RTx for ESRD with pretransplantation HbsAg positivity has acceptable graft function and patient/graft survival over 11 years follow-up and should be encouraged.

Outcome and prognostic factors of malaria-associated acute kidney injury requiring hemodialysis: A single center experience.

Acute kidney injury (AKI) is one of the most dreaded complications of severe malaria. We carried out prospective study in 2010, to describe clinical characteristics, laboratory parameters, prognostic factors, and outcome in 59 (44 males, 15 females) smear-positive malaria patients with AKI. The severity of illness was assessed using Acute Physiology and Chronic Health Evaluation (APACHE) II, Sequential Organ Failure Assessment (SOFA) score, Multiple Organ Dysfunction Score (MODS), and Glasgow Coma Scale (GCS) scores. All patients received artesunate and hemodialysis (HD). Mean age of patients was 33.63 ± 14 years. Plasmodium falciparum malaria was seen in 76.3% (n = 45), Plasmodium vivax in 16.9% (n = 10), and mixed infection in 6.8% (n = 4) patients. Presenting clinical features were fever (100%), nausea-vomiting (85%), oliguria (61%), abdominal pain/tenderness (50.8%), and jaundice (74.5%). Mean APACHE II, SOFA, MODS, and GCS scores were 18.1 ± 3, 10.16 ± 3.09, 9.71 ± 2.69, and 14.15 ± 1.67, respectively, all were higher among patients who died than among those who survived. APACHE II ≥20, SOFA and MODS scores ≥12 were associated with higher mortality (P < 0.05). 34% patients received blood component transfusion and exchange transfusion was done in 15%. Mean number of HD sessions required was 4.59 ± 3.03. Renal biopsies were performed in five patients (three with patchy cortical necrosis and two with acute tubular necrosis). 81.3% of patients had complete renal recovery and 11.8% succumbed to malaria. Prompt diagnosis, timely HD, and supportive therapy were associated with improved survival and recovery of kidney functions in malarial with AKI. Mortality was associated with higher APACHE II, SOFA, MODS, GCS scores, requirement of inotrope, and ventilator support.

Outcome of deceased donor renal transplantation in diabetic nephropathy: a single-center experience from a developing country.

BACKGROUND: Type 2 diabetes mellitus (DM) is the commonest cause of end-stage renal disease (ESRD) worldwide. Renal transplantation (RTx) is the best therapeutic modality for such patients. First-degree relatives of patients with type 2 DM have high risk of diabetes/pre-diabetes. Parents are often too old to be suitable donors, and siblings/children/spouse are either not suitable/acceptable or do not come forward for organ donation. This leaves deceased donation (DD) as only suitable donors. Data scarcity on DDRTx outcome in diabetic nephropathy (DN) prompted us to review our experience. This retrospective single-center 10-year study was undertaken to evaluate patient/graft survival, graft function, rejection episodes, and mortality in these patients. MATERIALS AND METHODS: Between January 2001 and March 2011, thirty-five DN-ESRD patients underwent DDRTx in our center following cardiac fitness assessment of recipients. All patients received single-dose rabbit-anti-thymocyte globulin for induction and steroids, calcineurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. Mean recipient age was 49.66 ± 6.76 years, and 25 were men. Mean donor age was 50 ± 16.45 years, 23 were men. RESULTS: Over a mean follow-up of 2.28 ± 2.59 years, patient and graft survival rates were 68.5% and 88.5%, respectively, with mean SCr of 1.9 ± 0.62 mg/dl. Delayed graft function was observed in 34.3% patients, and 25.7% had biopsy-proven acute rejection; 31.5% patients died, mainly because of infections (22.8%), coronary artery disease (2.86%), and cerebrovascular events (5.7%). CONCLUSION: DDRTx in patients with DN has acceptable graft function and patient/graft survival over 10-year follow-up in our center and, therefore, we believe it should be encouraged.
