A prospective evaluation was performed to study the potential benefits of the use of interleukin-2 receptor antibody (IL-2Rab) in the induction therapy with early elimination of steroid and reduction of tacrolimus dosage in liver transplant recipients among whom 94% had chronic hepatitis B infection. Thirty-one liver transplant recipients who underwent right-lobe live donor (n = 19) or cadaveric (n = 12) liver transplantation received IL-2Rab, basiliximab 20 mg intravenously within 6 hours of graft reperfusion and on postoperative day 4 (IL-2ab group). Two doses of steroid injection were given intraoperatively and on postoperative day 1. Postoperative immunosuppression was maintained with oral tacrolimus and mycophenolate mofetil without the use of steroids. The operative outcomes were compared with those of 49 patients who received standard immunosuppressive regimen consisting of tacrolimus and corticosteroid (steroid group). The overall postoperative morbidity and hospital stay were comparable between the 2 groups. There were significantly lower incidences of postoperative new-onset diabetes (0% vs 28%, P =.011), acute cellular rejection (6% vs 27%, P =.038), and cytomegalovirus (CMV) antigenemia (0% vs 18%, P =.011) in the IL-2Rab group compared with the steroid group. The blood cholesterol level at 6 months after transplantation was significantly lower in the IL-2Rab group (median, 4.0 vs 4.4 mmol/L, P =.007). On follow-up, none of the patients in the IL-2Rab group had hepatitis B viral breakthrough or hepatocellular carcinoma (HCC) recurrence, whereas 1 and 3 patients in the steroid group developed these complications, respectively. In conclusion, treatment of liver transplant recipients with IL-2Rab with early withdrawal of steroids and reduction of tacrolimus dosage is associated with lower incidences of postoperative new-onset diabetes, acute cellular rejection, and CMV antigenemia, as well as a lower serum cholesterol level. Further studies and long-term follow-up are required to document their potential benefits on hepatitis B and HCC recurrences.

Chronic HBsAg carriers are known to have a higher risk of hepatitis-related mortality and morbidity when undergoing kidney transplantation. Immunosuppressants might flare up the infection that could be fulminating. Lamivudine and mycophenolate mofetil (MMF) have been shown to be effective in inhibiting replication of hepatitis B virus (HBV). With these two drugs, hepatitis related adverse outcome might be preventable when these patients are being transplanted. Four Chinese adolescents with chronic HBV infection were transplanted in our Department from 1999 to 2001. Immunosuppresants included prednisolone, cyclosporin A and MMF; azathioprine was not used for its potentially liver toxic effect. Prophylactic lamivudine 3 mg/kg and maximum 100 mg daily was given just before transplantation and was continued afterwards. HBV status and liver enzymes were monitored serially. Patients were followed up for 26.0 +/- 10.3 (11-34) months post-transplant and no mortality was reported. All grafts were functioning and no rejection was noted. MMF and lamivudine were well tolerated. Alanine transaminase was only transiently elevated in the first 2 months post-transplant in all patients and became normal afterwards. The patients were clinically well and liver function was normal at the last follow-up. However, HBV DNA became positive in three patients after the transplantation. YMDD mutant HBV was negative in one patient and undeterminable in the other three due to low virus load. In summary, with prophylactic lamivudine and MMF, short-term follow-up showed that renal transplant might be feasible and safe in chronic HBV carriers.

To report a unique case of peripheral ulcerative keratitis secondary to hepatitis B virus (HBV)-associated cryoglobulinemia and vasculitis and its pharmacological and surgical treatment and 2-year follow-up.. A 52-year-old woman presented with unilateral eye pain and photophobia, arthralgia, remnants of a maculopapular rash, and subsequently facial numbness several weeks later. Her best spectacle-corrected visual acuity (BSCVA) in the affected eye was 20/80. Slit-lamp examination revealed severe superior corneal thinning without infiltrate. Corneal ulceration worsened until 10% of the cornea remained. Laboratory workup was positive for rheumatoid factor and revealed significantly decreased C4 complement, and HBV serology was positive.. Clinical history, examinations, and laboratory results suggest HBV-associated cryoglobulinemia and vasculitis. Management included prednisone, cyclophosphamide, and mycophenolate mofetil for immunosuppression and tenofovir for HBV treatment. Conjunctival resection and a glue patch were used to reduce inflammation and stabilize corneal melt. BSCVA improved after treatment was initiated. Two years after initial presentation, her BSCVA is 20/30, significantly improved from her vision at presentation.. Diagnosis of peripheral ulcerative keratitis requires thorough history and physical examinations given the numerous causes. Prompt treatment including immunosuppressive medication and, in this case, antiviral medication is crucial to preventing serious visual consequences including corneal perforation and blindness.

In kidney transplant recipients (KTRs) with hepatitis B virus (HBV) infection, immunosuppression may increase viral replication with increased risk for liver disease progression and HBV-related kidney diseases, factors that could adversely influence graft and patient outcomes. We aimed to analyze the impact of different phases of HBV infection on the outcomes in KTRs.. Using the Organ Procurement and Transplant Network/United Network for Organ Sharing database, we selected adult KTRs from 2001 to 2011 who received peri-operative antibody induction followed by calcineurin inhibitor/mycophenolate mofetil maintenance with/without steroid. The cohort was divided into 4 groups, based on the presence/absence of hepatitis B surface antigen (HBsAg) and core antibody (HBcAb) at the time of transplantation: group 1: HBsAg+/HBcAb- (acute infection); group 2: HBsAg+/HBcAb+ (developing immune response); group 3; HBsAg-/HBcAb+ (resolving infection); and group 4: HBsAg-/HBcAb- (HBV-naive). Graft and patient survivals were compared among the groups in a multivariate Cox model.. Adjusted overall graft (hazard ratio [HR], 0.97; 95% confidence interval [CI], 0.90-1.10; P = .58) and patient (HR, 0.95; 95% CI, 0.83-1.09; P = .52) survival rates were similar between groups 1 and 2, with inferior death-censored graft survival in group 1 (HR, 0.83; 95% CI, 0.71-0.98; P = .02). Adjusted over all graft (HR, 1.0; 95% CI, 0.90-1.00; P = .46) and patient (HR, 1.03; 95% CI, 0.90-1.10; P = .10) survival rates were similar between groups 3 and 4, and death-censored graft survival trended inferior in group 3 (HR, 0.97; 95% CI, 0.90-1.00; P = .05).. Our analysis supports a practice of delaying kidney transplantation in HBV-infected patients until they develop an immune response and preferably until the infection is cleared.

Drug adherence is one of the most important factors determining graft and patient survivals after liver transplantation. A systematic pharmaceutical educational approach has been implemented to improve adherence in immunosuppressive drugs therapy at Siriraj Hospital.. This study was a single-center cross-sectional study of liver transplant patients who received pharmaceutical care from transplant pharmacists. The clinical pharmacy services, including medication review to emphasize patients' knowledge and awareness of immunosuppressive and general drug therapies with the use of various tools, were used to educate the patients. Drug-related problems (DRPs) and pre- and post-transplantation educational tests (divided into 3 parts: immunosuppressants [12 points], drug monitoring [6 points], and general drugs [2 points]) were analyzed.. From October 2012 to September 2014, a total of 50 liver transplant recipients (86 visits) were enrolled. After the systematic pharmaceutical educational program, the average total score of post-transplantation educational test improved from 3.48 to 13.30 (P < .001). Likewise, the mean scores of all 3 parts significantly increased (part I: 2.28 vs 8.18 [P < .001]; part II: 0.75 vs 3.63 (P < .001); and part III: 0.46 vs 1.50 [P < .001]). The incidences of major DRPs, nonadherence, and adverse drug reactions were 8%, 4%, and 2%, respectively.. A systematic pharmaceutical educational approach can significantly improve patients' knowledge and awareness concerning immunosuppressive drug usage.

Reactivation of hepatitis B virus (HBV) is a complication of immunosuppressive treatment in patients with a history of HBV exposure.. Herein we have reported a case of reactivation after renal transplantation in a 52-year-old male chronic HBV carrier who was treated with hepatitis B immunoglobulin (HBIg) prophylaxis immediately after transplantation in addition to cyclosporine, mycophenolate mofetil and prednisolone for maintenance immunosuppression. After application of rituximab, the patient developed clinical hepatitis with a high load of HBV DNA. Sequence analysis of the surface (S) antigen corresponding to the amino acid residues 101-186 (including the a-determinant region) revealed a genotype D mutant strain, subtype ayw3 with a single amino acid substitution D144E within the S gene.. This case suggested that immunosuppressive treatment enhanced with rituximab promoted the emergence of an HBV mutant within the determinant region of the S antigen, which escaped HBIg immunoprophylaxis causing HBV reactivation in a kidney transplant recipient.
