Posterior reversible encephalopathy syndrome (PRES) as a complication of immunosuppressive therapy in renal transplantation in children.

Although kidney transplantation is by far the best method of renal replacement therapy, organ receiver is still not spared of eventual toxic consequences of drugs that are in charge of keeping the transplanted kidney functional. Both calcineurin inhibitors, of which tacrolimus more often, occasionally lead to neurotoxic side effects, mostly mild and reversible and dose-dependent in nature, but they can also be very severe or even fatal. It is very important to be aware of possible neurotoxic effects, to confirm them radiologically, and to prevent or reduce drug effects on nervous system. Sometimes the reduction of dose or substitution with another drug with similar mechanism effect is sufficient to terminate the neurotoxic effects of the drug and still not jeopardize the function of transplanted organ.

FibroTest/Fibrosure for significant liver fibrosis and cirrhosis in chronic hepatitis B: a meta-analysis.

OBJECTIVES: Extent of liver fibrosis is one of the most important factors in determining prognosis and the need for active treatment in chronic hepatitis B (CHB). Noninvasive alternatives such as FibroTest/Fibrosure (FT) have been developed in order to overcome the shortcomings of liver biopsy (LB). We aimed to systematically review studies describing the diagnostic accuracy of FT for predicting CHB-related fibrosis. METHODS: MEDLINE and EMBASE searches and hand searching methods were performed to identify studies that assessed the diagnostic accuracy of FibroTest in HB patients using LB as a reference standard. We used a hierarchical summary receiver operating curves model and the bivariate model to produce summary receiver operating characteristic curves and pooled estimates of sensitivity and specificity. RESULTS: We included 16 studies (N=2494) and 13 studies (N=1754) in the heterogenous meta-analysis for liver fibrosis and cirrhosis, respectively. The area under the hierarchical summary receiver operating curve for significant liver fibrosis and for all included studies was 0.84 (95% confidence interval (CI): 0.78-0.88). At the FT threshold of 0.48, the sensitivity, specificity, and diagnostic odds ratio (DOR) of FT for significant fibrosis were 61 (48-72%), 80 (72-86%), and 6.2% (3.3-11.9), respectively. The area under the hierarchical summary receiver operating curve for liver cirrhosis and for all included studies was 0.87 (95% CI: 0.85-0.90). At the FT threshold of 0.74, the sensitivity, specificity, and DOR of FT for cirrhosis were 62 (47-75%), 91 (88-93%), and 15.7% (8.6-28.8), respectively. CONCLUSIONS: FibroTest is of value in exclusion of patients with CHB-related cirrhosis, but has suboptimal accuracy in the detection of significant fibrosis and cirrhosis. It is necessary to further improve the test or combine it with other noninvasive modalities in order to improve accuracy.

Pregnancy in renal transplantation.

UNLABELLED: Pregnancy in kidney transplantation is, considering its numerous complications, listed in category of high-risk pregnancies. Complications occur as consequence of action of immunosuppressant drugs and mutual interactions of graft on pregnancy and pregnancy on graft. To asses conception it is necessary for female patient to fulfill conditions after which planning and management of pregnancy are carried out. Planning means a list of actions which altogether have as a goal to decrease risk factors for future mothers and for babies as much as possible. Pregnancy management is also procedural, including numerous hospitalizations, in which pregnancy, fetus and renal function are controlled, on-time identifying potentially dangerous complications and solving ones that might have already occurred. With all given precautions there is still no guarantee for successful pregnancy termination, although given measurements significantly improve possibilities of normal childbirth, like those in general population. KEYWORDS: renal transplantation, pregnancy.

One hundred kidney transplantations in Tuzla.

INTRODUCTION: Kidney transplantation assures considerably better quality of life than the treatment of end-stage renal disease patients with dialysis. GOAL: Authors intended to present results of kidney transplantations that were performed for over 13 years in UCC Tuzla. EXAMINEES AND METHODS: Total of 100 transplantations have been done over 13 years. The gender and age structure have been presented, as well as number of transplantations per year, type of transplantation (living related donor, living unrelated donor, deceased donor), number and percentage of donors and results of transplantations expressed as survival of both the patient and transplanted kidney/ renal graft. We also wanted to presented other important events such as dates of introduction of certain drugs, dates of first cadaver transplantation, transplantation with desensitization protocols and dates of first living unrelated (spousal/emotional) transplantation. RESULTS: The survival of patients and renal grafts were demonstrated by Kaplan-Meier curve, and obtained results were fully in range of results recommended in other literature and by other authors. One-year survival of graft is 94%, with five-year survival being 75%. One-year survival of patients is 95%, and five-year survival of patients was 84%. DISCUSSION: Our results have been compared to those from other studies, gaining suggestions for transplantation improvement. CONCLUSION: Among all modifications of renal replacement therapy transplantation is by far the method of choice because, its well known advantages aside, it also has an economical advantage over chronic treatment with dialysis and it should therefore become interesting to healthcare systems.
