Clinical manifestations of dengue infection in renal transplant recipients were similar to that in general population. However, leucopenia necessitating temporary withdrawal of immunosuppression was common. Renal dysfunction was frequent but completely reversible.

Colovesical fistula per se is a rare condition and most commonly occurs secondary to diverticular disease in normal patients. Colovesical fistula in the setting of post-renal transplantation is even rarer and very few cases have been reported in literature. Patients with autosomal-dominant polycystic kidney disease (ADPKD) are predisposed to diverticulosis and hence are at a higher risk for fistula formation. Herein, we report a case of colovesical fistula in a renal allograft recipient with ADPKD in the absence of diverticulosis. The patient was successfully operated and is stable with no complications at 1-year follow-up.

Objectives:This study aimed to determine the prevalence of immediate posttransplant hyperglycemia and new onset diabetes after renal transplantation (NODAT). It also aims at answering whether posttransplant hyperglycemia per se is a risk factor for future development of NODAT.Methods:A retrospective study was conducted among patients undergoing kidney transplantation under a single surgical unit in a tertiary care hospital in the past 5 years. All known patients with diabetes were excluded from the study. Immediate postoperative hyperglycemia was defined as random blood sugar (RBS) ≥200 mg/dl or requirement of insulin. NODAT was defined as fasting plasma glucose ≥126 mg/dl or RBS ≥200 mg/dl or if the patient is receiving therapy for glycemic control at 6 weeks or 3 months posttransplantation.Results:The study population included 191 patients. The overall prevalence of posttransplant hyperglycemia and NODAT was 31.4% and 26.7%, respectively. NODAT developed in 28 patients (46.7%) of those who had posttransplant hyperglycemia. Thus, posttransplant hyperglycemia was associated with a fourfold increased risk of NODAT (P = 0.000). Posttransplant hyperglycemia was associated with increased infections (P = 0.04) and prolonged hospital stay (P = 0.0001). Increased age was a significant risk factor for NODAT (P = 0.000), whereas gender, acute rejection episodes, cadaveric transplant, hepatitis C virus status, human leukocyte antigen mismatch, and high calcineurin levels were not significantly associated with the future development of NODAT.Conclusion:The significant risk of NODAT posed by posttransplant hyperglycemia makes it prudent to follow up these patients more diligently in a resource-limited setting wherein routine monitoring in all patients is cumbersome.

A 45-year-old man presented 4 months after ABOi renal transplantation with febrile illness and bicytopenia necessitating cessation of mycophenolate mofetil. Dengue non-structural protein 1 antigen (NS1 Ag) test was positive. Lowest total leucocyte count was 3.1×10/L and platelet count was 14×10/L. As fever subsided, patient became tachypneic with abdominal distention and hypotension. Ultrasonographic evaluation revealed ascites, gall bladder wall oedema and bilateral pleural effusion consistent with dengue capillary leak syndrome. He developed massive ascites with abrupt weight gain of 4 kg within 24 hours and worsening renal dysfunction. Patient was deteriorating rapidly in spite of adequate supportive care and we gave a trial of intravenous immunoglobulin (0.5 g/kg/day) for 5 days. Patient improved from day 2, and by day 3, he became haemodynamically stable and recovered completely. Patient was stable at discharge and is on regular follow-up.
