UNLABELLED Delayed kidney graft function and acute rejection in the early post-transplant period affect both short and long-term allograft survival. Allograft rejection, as an inflammatory state, results in increased erythropoietin resistance, which leads to decreased haemoglobin (Hb) level. We conducted this study to evaluate whether inflammation in the early post-transplant period could predict later anemia.This is a retrospective cohort study based on the analysis of 64 existing clinical records. PREDICTOR White blood cells (WBC) count obtained by the end of the first week post-transplant (W1). Covariates: Donor's age, recipient's age and sex. OUTCOME Anemia identified at 12 months (M12) post engraftment. Median WBC count at W1 was 9,5 x103/microL (5th - 95th percentile 5,2 x103/microL -17,8 x103/microL). Mean Hb values at M12 were 129,9 +/- 20,3 g/L, in males 136,2 +/- 20,1 g/L and in females 119,4 +/- 16,2 g/L. The significant correlation was found between WBC at W1 and Hb at M12. Pearson coefficient of correlation r was -0,26, and 95% confidence interval (CI) for r was -0,47 to -0,015 (p=0,03). Univariate logistic regression showed significant association between WBC at W1 and Hb at M12 (OR 1,20; 95% CI 1,04 to 1,39, p=0,01). After the adjustment for donor's and recipient's age by transplantation and recipient's sex, multiple regression showed that WBC count remained predictive of anemia at M12 (OR 1,17; 95% CI 1,01 to 1,36, p=0,03). Early post-transplant inflammatory response predicts later anemia in kidney transplant recipients. An increase in WBC count in the first week post-transplant by 109/L increases the risk for anemia after twelve months by 17%.

The aim of this study was to evaluate whether anemia identified earlier than 3 months postengraftment in modern era could be predictive of anemia at 12 months. Cross-sectional and cohort studies based on retrospective analysis of existing clinical records were performed. Data on recipient's age at transplantation, follow-up serum creatinine (SCR) and hemoglobin (Hb) on day 7 (D7), at month 1 (M1) and at month 3 (M3) postengraftment were collected. Outcome was anemia identified at 12 months (M12) postengraftment. There were 75 patients on D7, 74 at M1 and 61 at M3. Multiple linear regression model that included recipient's age at transplantation, Hb and creatinine on D7 and tested the risk for anemia at M12 retained only the age in the model, with the coefficient of 0,84 (P=0,001). The same model at M1 retained Hb and age, with the coefficients of 0,26 (P=0,03) and 0,81 (P=0,0002), respectively and at M3 it retained Hb and age, with the coefficients of 0,41 (P=0,004) and 0,70 (P=0,003), respectively. Anemia identified at M1 after renal transplantation is predictive of anemia at M12.

Background: Accurate estimations of hepatitis B virus transmission risk for any region in Bosnia and Herzegovina are not clearly established. We aimed to determine levels of risk associated with intrafamilial transmission of hepatitis B infection within families in our region. Patients and Methods: Family members of 81 chronic carriers of hepatitis B surface antigen (>6 months positive and considered as index case) were tested for hepatitis B markers. For family members, we recorded their age, sex, and family relationship to the index case, and vaccination status. Results: The proportion of HBsAg positive family members was 25/207 (12.1%), while the proportion of family members with evidence of exposure to HBV was 80/207 (38.6%). Only 17/207 (8.2%) family members had evi--dence of past HBV vaccination. Age was found to be a significant predictor of HBV exposure of family members (odds ratio 1.05, 95% CI 1.03-1.07, P< .001). In a multivariate analysis, HBsAg positivity was associated with a female index case (odds ratio 11.31, 95% CI 3.73-34.32, P< .001), HBeAg positivity in the index case (odds ratio 5.56, 95% CI 1.80-17.23, P< .005) and being a mother of the index case (odds ratio 9.82, 95% CI 2.43-39.68,P< .005). A female index case (odds ratio 4.87, 95% CI 2.21-10.72, P< .001), HBeAg positivity in the index case (odds ratio 3.22, 95% CI 1.15-9.00, P< .05) and being a mother of the index case (odds ratio 3.72, 95% CI 1.19-11.64, P< .05) were also risk factors for HBV exposure among family members. The combination of HBeAg positivity and female index case was a significant predictor for HBsAg positivity of family members (odds ratio 70.39, 95% CI 8.20-604.61, P< .001). Conclusions: Children of HBeAg positive mothers are at highest risk for becoming chronic carriers them--selves and generally, the combination of female sex and HBeAg positivity dramatically increases the chances of HBV transmission within the family.

The aim of this study was to evaluate the results of percutaneous drainage with single-session alcohol sclerotherapy in the treatment of symptomatic simple renal cysts. Thirty patients (16 men and 14 women, average age 54,7+/-11,3 years) with simple renal cysts were treated by ultrasound guided percutaneous aspiration and single-session alcohol sclerotherapy. Patient demographics, clinical characteristics, treatment outcome and complications were analyzed. Average reduction of cyst volume was 91,2%. Complete and partial resolution occurred in 10 (33%) and 14 (47%) cysts, respectively. Six cases were defined as failure with reduction of cyst volume <80%. Flank pain improved in all patients, regardless of complete or partial resolution. Minor complications occurred in 8 patients. The hospital stay was one day for all patients. Treatment of simple renal cysts is indicated when the cysts are sufficiently large and cause complaints or when associated with complications. Percutaneous treatment with alcohol sclerotherapy of benign renal cysts can be performed safely and effectively.

To the Editor: We read the editorial of Professors Matko and Ana Marusic in the December issue of the Croatian Medical Journal (CMJ) (1). With regret we learned that the policy of the editorial board of CMJ, which created one outstanding, general medical journal, is questioned. We have been reading the CMJ for many years and published several articles in it. We consider Prof. Marusic not only the editor of an excellent journal, but the teacher of medical writing as well. We were aware that, because of our lack of experience, the article we were sending was incomplete, but we were also aware that it would not have the destiny like in other journals, as Prof. Marusic would correct the article with us. The comments in his char acteristic, amusing way what to correct, omit, or add, were making the article better and better… After attending Prof. Marusic’s workshop of medical writing, some on us published the articles in very prestigious journals. We are very grateful to him for his help. Prof. Marusic placed his editorial board at the disposal of the postgraduate students of Tuzla Medical University School of Medicine, as the assistance during the writing of articles which even do not have to be sent to the CMJ – with the wish to expand the awareness of necessity
