Abstract
BACKGROUND: New-onset diabetes after kidney transplant (NODAT) is a severe metabolic complication that frequently occurs in recipients following transplantation.
AIM: The study aims to verify NODAT, compare cases and non-cases of this entity, and explore potential predictors in recipients within 1 year following kidney transplantation.
METHODS: The research is a retrospective study of 90 renal transplant recipients (n = 90). Demographic factors and clinical aspects were analyzed using non-Bayesian statistics and machine learning (ML). The clinical aspects included the glycated hemoglobin (HbA1c) level, associated viral infections (hepatitis B virus [HBV], hepatitis C virus [HCV], and cytomegalovirus [CMV]), prior kidney transplant, hemodialysis status, body mass index (BMI) at transplant time, and 3 months later, primary causes of renal failure, and post-transplant therapeutics. All individuals were on cyclosporine and prednisolone treatment.
RESULTS: The mean age was 39 (±1.5) years; recipients included 27 females (30%) and 63 males (70%). Donor type was live related (16, 17.8%) or live unrelated (74, 82.2%); 27 recipients (30%) had O+ blood group, while 70% belonged to other groups. Thirteen recipients (14.4%) were not on dialysis. Only 32 individuals (35.6%) developed NODAT. Concerning virology, confirmed by real-time polymerase chain reaction before transplantation, 19 recipients (21.1%) were CMV positive, 9 (10%) were HCV positive, and 2 (2.2%) had HBV.
CONCLUSIONS: In reconciliation with frequentist statistics, the dual ML model validated several predictors that either negatively (protective) or positively (harmful) influenced HbA1c level, the majority of which were significant at 95% confidence interval. Individuals who are HCV and CMV positive are predicted to develop NODAT. Further, older individuals, with blood group O+ve, prior history of hemodialysis, a relatively high BMI before the transplant, and receiving higher doses of prednisolone following the transplant are more likely to develop NODAT. The current study represents the first research from Iraq to explore NODAT predictors among kidney transplant recipients using frequentist statistics and artificial intelligence models.

Abstract
Hepatitis C virus (HCV) infection in kidney transplantation is an important issue with effects on patient and graft survival. The current standard of care involves using oral Direct Acting Antiviral drugs. Till recently, pre-transplant treatment with interferon was the only option for treatment. We studied 677 consecutive kidney transplant recipients with HCV infection. 5.2% patients had evidence of HCV infection. 2.0% were newly detected to have HCV infection after transplant (de novo HCV group). Nearly 28.6% had negative antibody tests but positive Nucleic Acid Test at the time of diagnosis. Eighty-five percent of pre-transplant HCV-positive patients were treated with interferon-based regimens. Early virologic response was seen in 66.6%. End of treatment response was achieved by 94.1%. Sustained virologic response was seen in 81.2%. Overall, patient and graft survival were not different between HCV and control groups (log-rank P = 0.154). Comparing HCV and control groups, there was a tendency toward increased fungal (11.4% vs. 5.6%, P = 0.144) and CMV infections (25.7% vs. 17.1%, P = 0.191) in the HCV group, though it did not reach statistical significance. Eighty-percent of the interferon-treated patients suffered side effects. On comparing, the pre-transplant HCV-positive group (85% treated) with the de novo HCV group (none treated), the de novo group had significantly reduced patient survival (P = 0.020) and NODAT (35.7 vs 4.8%, P = 0.028), and a tendency toward higher CMV infections (35.7% vs 19%, P = 0.432). In addition, death and hepatic complications (decompensated liver disease, fibrosing cholestatic hepatitis) occurred only in de novo HCV group. These results highlight the need for continued post-transplant treatment of HCV positive patients. The newer anti-HCV drugs are expected to fulfill this felt-need in kidney transplantation but long-term results are awaited. This study can serve as a benchmark for future studies to compare the long-term effect of Direct Acting Antiviral drugs.

Abstract
Objective To examine the association between HCV infection and the occurrence of post-transplant diabetes mellitus (PTDM) among renal transplant patients. Design Meta-analysis of observational studies. Data Sources We retrieved studies published in any language by systematically searching Medline, and Embase and by manually examining the references of the original articles, reviews, and monographs retrieved. Review Methods We included cohort and case-control studies reporting relative risk estimates and 95% confidence intervals (CIs) for PTDM occurrence with HCV after renal transplantation. Thirteen studies providing information on a total of 30,099 unique patients were included in our meta-analysis. Results Study-specific relative risks were weighted by the inverse of their variance to obtain fixed- and random-effects pooled estimates. The pooled relative risk (RR) for PTDM after RT was 2.73 with a 95% confidence interval (CI) of 1.94; 3.83 (10 studies). In a stratified analysis including only large studies (2 studies), the pooled RR was 1.36 (95% CI, 1.21; 1.54). Egger's regression test showed some evidence of publication bias (p=0.0001), but our sensitivity analysis showed that this issue did not meaningfully change the results. Conclusions Our study shows a marked increase of the risk of post-transplant diabetes mellitus in anti-hepatitis C virus-positive renal transplant recipients. The excess risk of death in hepatitis C virus-positive renal transplant recipients may be at least partially attributed to post-transplant diabetes mellitus with its attendant complications.

Abstract
Chronic hepatitis C virus (HCV) infection remains an important health problem, which is associated with deleterious consequences in kidney transplant recipients. Besides hepatic complications, several extrahepatic complications contribute to reduced patient and allograft survival in HCV-infected kidney recipients. However, HCV infection should not be considered as a contraindication for kidney transplantation because patient survival is better with transplantation than on dialysis. Treatment of HCV infection is currently interferon-alpha (IFN-α) based, which has been associated with higher renal allograft rejection rates. Therefore, antiviral treatment before transplantation is preferable. As in the nontransplant setting, IFN-free treatment regimens, because of their greater efficacy and reduced toxicity, currently represent promising and attractive therapeutic options after kidney transplantation as well. However, clinical trials will be required to closely evaluate these regimens in kidney recipients. There is also a need for prospective controlled studies to determine the optimal immunosuppressive regimens after transplantation in HCV-infected recipients. Combined kidney and liver transplantation is required in patients with advanced liver cirrhosis. However, in patients with cleared HCV infection and early cirrhosis without portal hypertension, kidney transplantation alone may be considered. There is some agreement about the use of HCV-positive donors in HCV-infected recipients, although data regarding posttransplant survival rates are controversial.

Abstract
Aim of this study was to investigate the mechanism/s associating hepatitis C virus (HCV) infection and posttransplant diabetes mellitus in kidney recipients. Twenty HCV-positive and 22 HCV-negative kidney recipients, 14 HCV-positive nontransplant patients and 24 HCV-negative nontransplant (healthy) subjects were analyzed. A 3-h intravenous glucose tolerance test was performed; peripheral insulin sensitivity was assessed by minimal modeling. Pancreatic insulin secretion, hepatic insulin uptake, pancreatic antibodies and proinflammatory cytokines in serum (tumor necrosis factor-alpha, intereukin-6, high-sensitive C-reactive protein) were also assessed. HCV-positive recipients showed a significantly lower insulin sensitivity as compared to HCV-negative recipients (3.0 +/- 2.1 vs. 4.9 +/- 3.0 min(-1).microU.mL(- 1).10(4), p = 0.02), however, insulin secretion and hepatic insulin uptake were not significantly different. Pancreatic antibodies were negative in all. HCV status was an independent predictor of impaired insulin sensitivity (multivariate analysis, p = 0.008). The decrease of insulin sensitivity due to HCV was comparable for transplant and non-transplant subjects. No significant correlation was found between any of the cytokines and insulin sensitivity. Our results suggest that impaired peripheral insulin sensitivity is associated with HCV infection irrespective of the transplant status, and is the most likely pathogenic mechanism involved in the development of type 2 diabetes mellitus associated with HCV infection.

Abstract
This review focuses on the relationship between hepatitis C virus (HCV) infection and glucose metabolism derangements. Cross-sectional and longitudinal studies have shown that the chronic HCV infection is associated with an increased risk of developing insulin resistance (IR) and type 2 diabetes (T2D). The direct effect of HCV on the insulin signaling has been analyzed in experimental models. Although currently available data should be considered as preliminary, HCV seems to affect glucose metabolism via mechanisms that involve cellular pathways that have been implicated in the host innate immune response. IR and T2D not only accelerate the histological and clinical progression of chronic hepatitis C, but also reduce the early and sustained virological response to interferon-alpha-based therapy. Thus, a detailed knowledge of the mechanisms underlying the HCV-associated glucose metabolism derangements is warranted, in order to improve the clinical management of chronic hepatitis C patients.

Abstract
Chronic infection with hepatitis C virus (HCV) is an important global health problem. The prevalence of HCV is significantly higher in haemodialysis and kidney transplant patients, as compared to the general population. In spite of the relatively milder liver disease activity reported in HCV-infected haemodialysis patients, HCV infection adversely affects survival. Likewise, HCV has a detrimental effect on both patient and graft survival after kidney transplantation. However, patient survival is significantly better with kidney transplantation compared to remaining on dialysis; therefore, HCV infection alone should not be a contraindication to transplantation. Combination antiviral therapy with pegylated interferon-alpha and low-dose ribavirin is currently evolving in haemodialysis patients. Interferon-alpha (standard/pegylated) is relatively contraindicated after kidney transplantation because of an increased risk of allograft rejection. Therefore, antiviral treatment of transplant candidates while on dialysis remains the best option and may avoid the risk of HCV-associated liver and renal disease after transplantation. Large multi-centre clinical trials are required in HCV-infected haemodialysis and kidney transplant patients in order to define optimal therapeutic strategies before and after transplantation.

Abstract
Liver disease secondary to chronic hepatitis C virus (HCV) infection is an important cause of morbidity and mortality in dialysis patients and kidney transplant recipients. Evaluation of patients with chronic HCV infection is warranted to determine stage of disease and the need for HCV therapy. Although combination therapy with interferon (IFN) plus ribavirin is the standard of care for chronic HCV infection, IFN monotherapy is recommended in dialysis patients because ribavirin is contraindicated in the presence of renal failure. The goals of pretransplantation HCV therapy are to decrease the risk for progression of HCV-associated liver disease, stabilize renal function in patients with HCV-related glomerulopathy, and prevent development of HCV-associated renal disease after transplantation. Posttransplantation HCV therapy is generally not recommended because of concerns regarding risk for precipitating acute rejection; however, antiviral therapy may be indicated to treat HCV-related glomerulopathy or prevent progression of chronic hepatitis C in patients with more advanced stages of fibrosis. When treatment is required, restored renal function allows use of combination therapy with IFN and ribavirin. Limitations of current HCV therapy include lack of tolerability and suboptimal response rates. New antiviral agents that can be used in dialysis patients (e.g., ribavirin alternatives) and in the posttransplantation setting (e.g., IFN alternatives) are needed to improve outcomes in these populations.

Abstract
Patients with chronic hepatitis C virus (HCV) infection have a significantly increased prevalence of type 2 diabetes mellitus compared to controls or HBV-infected patients. Moreover, the incidence rate of post-liver transplantation diabetes mellitus (PTDM) also appears to be higher among patients with HCV infection. PTDM is often associated with direct viral infection, autoimmune disorders, and immunosuppressive regimen. Activation of tumor necrosis factor-α may be the link between HCV infection and diabetes. In this article, we reviewed the epidemiologic association between HCV infection and PTDM, highlighting the most recent pathophysiologic insights into the mechanisms underlying this association.

Abstract
Hepatitis C virus (HCV) infection has a detrimental role on patient and graft survival after renal transplantation (RT). Some studies have also implicated HCV in the development of post-transplant diabetes mellitus (PTDM). We conducted a systematic review of the published medical literature of the relationship between anti-HCV seropositive status and DM after RT. The risk of DM occurrence in anti-HCV-positive and -negative patients after RT was regarded as the most reliable outcome end-point. We used the random effects model of DerSimonian and Laird to generate a summary estimate of the Odds Ratio (OD) of new onset DM in HCV-positive and -negative patients after kidney transplantation. Ten studies involving 2502 unique RT recipients were identified. The incidence of PTDM after RT ranged between 7.9% and 50%. The summary estimate for adjusted OR was 3.97 with a 95% confidence interval (CI) of 1.83-8.61 (p-value for homogeneity <0.0473). Thus, pooling of study results demonstrated the presence of a significant link between anti-HCV seropositive status and DM after RT. This relationship provides one potential explanation for the adverse effects of HCV on patient and graft survival after RT.

Abstract
New-onset diabetes mellitus after transplantation is characterized by decreased insulin secretion and increased insulin resistance secondary to the effects of immunosuppression. Although impaired beta cell function appears to be the primary mechanism of calcineurin inhibitor-induced new-onset diabetes, impaired peripheral glucose utilization also appears to contribute to insulin resistance and abnormal glucose metabolism. Because transplant recipients who develop new-onset diabetes mellitus after transplantation are at increased risk for infections, cardiovascular disease, and poor patient and graft survival, all patients should undergo careful assessment of risk for diabetes prior to transplantation and regular screening for the development of hyperglycemia thereafter. For patients in high-risk groups, including certain ethnic backgrounds, older adults, and the very young, and patients with hepatitis C, consideration should be given to initiating immunosuppressive therapy with agents that are less diabetogenic. Recent guidelines include more stringent criteria for diagnosis and stress the importance of strict glycemic control. Diet, exercise, and weight management are core components of treatment with addition of oral hypoglycemic agents and/or insulin as needed to achieve control. Concomitant measures include aggressive control of lipids and blood pressure to reduce the risk of cardiovascular disease. New-onset diabetes after transplantation is a serious issue affecting patient and graft outcomes and warrants the attention of all health care professionals involved in assessing and managing the transplant recipient.

Abstract
UNLABELLED Extensive clinical use has confirmed that tacrolimus (Prograf) is a key option for immunosuppression after transplantation. In large, prospective, randomised, multicentre trials in adults and children receiving solid organ transplants, tacrolimus was at least as effective or provided better efficacy than cyclosporin microemulsion in terms of patient and graft survival, treatment failure rates and the incidence of biopsy-proven acute and corticosteroid-resistant rejection episodes. Notably, the lower incidence of rejection episodes after renal transplantation in tacrolimus recipients was reflected in improved cost effectiveness. In bone marrow transplant (BMT) recipients, the incidence of tacrolimus grade II-IV graft-versus-host disease was significantly lower with tacrolimus than cyclosporin treatment. Efficacy was maintained in renal and liver transplant recipients after total withdrawal of corticosteroid therapy from tacrolimus-based immunosuppression, with the incidence of acute rejection episodes at up to 2 years' follow-up being similar with or without corticosteroids. Tacrolimus provided effective rescue therapy in transplant recipients with persistent acute or chronic allograft rejection or drug-related toxicity associated with cyclosporin treatment. Typically, conversion to tacrolimus reversed rejection episodes and/or improved the tolerability profile, particularly in terms of reduced hyperlipidaemia. In lung transplant recipients with obliterative bronchiolitis, conversion to tacrolimus reduced the decline in and/or improved lung function in terms of forced expiratory volume in 1 second. Tolerability issues may be a factor when choosing a calcineurin inhibitor. Cyclosporin tends to be associated with a higher incidence of significant hypertension, hyperlipidaemia, hirsutism, gingivitis and gum hyperplasia, whereas the incidence of some types of neurotoxicity, disturbances in glucose metabolism, diarrhoea, pruritus and alopecia may be higher with tacrolimus treatment. Renal function, as assessed by serum creatinine levels and glomerular filtration rates, was better in tacrolimus than cyclosporin recipients at up to 5 years' follow-up. CONCLUSION Recent well designed trials have consolidated the place of tacrolimus as an important choice for primary immunosuppression in solid organ transplantation and in BMT. Notably, in adults and children receiving transplants, tacrolimus-based primary immunosuppression was at least as effective or provided better efficacy than cyclosporin microemulsion treatment in terms of patient and graft survival, treatment failure and the incidence of acute and corticosteroid-resistant rejection episodes. The reduced incidence of rejection episodes in renal transplant recipients receiving tacrolimus translated into a better cost effectiveness relative to cyclosporin microemulsion treatment. The optimal immunosuppression regimen is ultimately dependent on balancing such factors as the efficacy of the individual drugs, their tolerability, potential for drug interactions and pharmacoeconomic issues.

Abstract
OBJECTIVE The incidence of posttransplantation diabetes mellitus (PTDM) has been reported to vary according to different study populations or different definitions. In this study, using American Diabetes Association criteria, the incidence and clinical characteristics of PTDM in Korean renal allograft recipients undergoing tacrolimus-based immunosuppression were examined. RESEARCH DESIGN AND METHODS A total of 21 patients taking tacrolimus as primary immunosuppressant were recruited and tested with a serial 75-g oral glucose tolerance test at 0, 1, 3, and 6 months after renal transplantation. RESULTS The cumulative incidence of PTDM was 52.4% at 1 month and 57.1% at 3 and 6 months. The baseline characteristics of the PTDM group were old age (especially >40 years), a high BMI, a high fasting glucose level, a high plasma insulin level, and increased insulin resistance. Among these parameters, old age was the only independent risk factor. The insulin secretory capacity in the PTDM group was maximally suppressed 3 months after transplantation. Thereafter, it was gradually restored along with dose reduction of tacrolimus. CONCLUSIONS Routine screening for PTDM is necessary in patients over 40 years of age who are undergoing a relatively higher dose tacrolimus therapy during the early course of postrenal transplantation.
