    Objectives: This study sought to elucidate the status of calcium, phosphorus, and parathyroid hormone in patients following kidney transplant. Materials and Methods: In this cross-sectional study, 20 renal transplant recipients were evaluated. For each patient, age, sex, time since transplant, and body weight were recorded. Inclusion criteria were age > 14 years and good allograft function defined as a serum creatinine level < 132.6 µmol/L for at least 6 months after transplant. Exclusion criteria were immunosuppressive therapy other than the standard triple regimen (cyclosporine, prednisolone, and mycophenolate mofetil or azathioprine) and use of any drug known to alter calcium hemostasis. Levels of 24-hour urine calcium, phosphorus, creatinine, and uric acid, as well as concentrations of hemoglobin, serum creatinine, calcium, and phosphorus were measured. To obtain a mean value of serum intact parathyroid hormone in transplant recipients at our center, serum intact parathyroid hormone levels were additionally quantitated in another group of 30 renal transplant recipients. Results: The mean hemoglobin level was 135.6 ± 17.7 g/L, the mean serum creatinine level was 105.0 ± 15.3 µmol/L, and the mean serum calcium and phosphorus levels were 2.25 ± 0.17 mmol/L (normal range, 2.02-2.60 mmol/L) and 1.28 ± 0.24 mmol/L (normal range, 0.81-1.61 mmol/L), respectively. The mean serum intact parathyroid hormone level was 33.17 ±14.67 ng/L (normal range, 10-60 ng/L). Mean 24-hour urine calcium and phosphorus values were 2.32 ± 1.68 mmol/day (normal, 2.49-6.24 mmol/day) and 19.77 ± 8.31 mmol/day (normal, 12.91-41.98 mmol/day), respectively. A positive correlation was found between serum calcium and alkaline phosphatase levels (r = +0.71, P = .006). Hemoglobin level was negatively correlated with serum phos­phorus level (r = –0.65, P = .003) and sex (r = –0.57, P = .003) and positively correlated with urine creatinine levels (r = +0.69, P = .001). Conclusions: Renal transplant recipients with stable allograft function may have normal serum calcium, phosphorus, and intact parathyroid hormone levels. However, presence of hypocalciuria and elevated serum alkaline phosphatase levels might imply impaired calcium metabolism in these patients.

    Renal Allograft Abscesses Following Transplant: Case Report and Literature Review
    (Başkent Üniversitesi, 2007-12) Shoja, Mohammadali M.; Varshochi, Mojtaba; Tubbs, R. Shane; Etemadi, Jalal; Ardalan, Mohamad R.
    Intrarenal and perinephric abscess formations are infrequent infectious complications in kidney allograft recipients. A 37-year-old man who was a victim of mustard gas chemical weapons from the Iran-Iraq war received a live-donor kidney transplant for end-stage renal disease. The posttransplant course was complicated by clinical rejection, which subsided after a 2-week infusion of antithymocyte globulin. One month subsequent to this, the patient presented with renal allograft dysfunction and multiple intrarenal abscesses. Culture from the purulent aspirate of a percutaneously drained renal abscess revealed multidrug-resistant Pseudomonas aeruginosa. A concomitant acute cytomegalovirus infection was detected based on positive serologic tests. Treatment with intravenous meropenem (3 g/day for 3 weeks) and oral ciprofloxacin was begun, which resulted in the complete resolution of the intrarenal abscesses. To our knowledge, this report represents the first description of pseudomonal renal abscesses in a renal transplant recipient. A review of the relevant literature is presented.
