AIM To evaluate the clinical impact of corticosteroids (CS) overuse in inflammatory bowel disease (IBD) patients. Excessive use of CS could delay more efficacious treatment and may indicate poor quality of care. METHOD This is a two-phase study that used Steroid Assessment Tool (SAT) to measure corticosteroid exposure in IBD patients. In the first phase, data from 211 consecutive ambulatory patients with IBD (91 with ulcerative colitis, 115 with Crohn's disease, and five with unclassified inflammatory bowel disease) were analysed by SAT. In the second phase, one year after data entry, clinical outcome of patients with corticosteroids overuse was analysed. RESULTS Of the 211 IBD patients, 132 (62%) were not on corticosteroids, 45 (22%) were corticosteroid-dependent, and 34 (16%) used corticosteroids appropriately, according to the European Crohn's and Colitis Organization guidelines. In the group of patients with ulcerative colitis, 57 (63%) were not on corticosteroids, 18 (20%) were corticosteroid-dependent, and 16 (16%) used corticosteroids appropriately; in the group of patients with Crohn's disease 70 (61%), 27 (23%) and 18 (16%), respectively. Overall, 24 (out of 45; 53%) patients with IBD could avoid the overuse of corticosteroids if they had a timely change of the treatment, surgery, or entered a clinical trial. CONCLUSION An excessive corticosteroid use can be recognized on time using the SAT. We have proven that excessive corticosteroid use could be avoided in almost half of cases and thus the overuse of CS may indicate poor quality of care in those patients.

The John Cunningham virus (JCV) is a polyomavirus that usually infects people at a young age and does not cause any symptoms in immunocompetent individuals. However, in immunocompromised individuals, such as kidney transplant recipients, JCV can cause severe and potentially fatal disease. Unfortunately, JCV has not been researched as extensively as the BK virus and is not mentioned in relevant kidney transplant guidelines. This lack of attention to JCV can lead to less consideration in kidney transplant patients’ care. Surveillance using locally available diagnostic methods is of the utmost importance. The presence of JCV can be diagnosed with urine decoy cells, viruria, or viremia verified by the PCR method. A low threshold for considering JCV as a possible cause of any neurological or renal dysfunction in kidney transplant recipients must be maintained. In such cases, kidney and brain biopsy are indicated. Maintaining the appropriate immunosuppression while avoiding over-immunosuppression to prevent JCV disease is crucial, and the approach should be individual, according to overall immunological risk. We hypothesize that the presence of the JCV can indicate overt immunosuppression and identify kidney transplant recipients more prone to opportunistic infections and diseases, including some malignancies. To explore that, future observational studies are needed.

Aim To analyse prevalence of metabolic syndrome (MS) in kidney transplant recipients at the University Clinical Centre Tuzla in Bosnia and Herzegovina (B&H), and determine effects of a modern drug therapy in achieving target metabolic control in kidney transplant patients. Methods A single-centre prospective study that included 142 kidney transplant patients over one year follow-up period was conducted. Patient data were collected during post-transplant periodical controls every 3 months including data from medical records, clinical examinations and laboratory analyses. Results Out of 142 kidney transplant patients, MS was verified in 85 (59.86%); after a pharmacologic treatment MS frequency was decreased to 75 (52.81%). After a one-year period during which patients were receiving therapy for MS, a decrease in the number of patients with hyperlipoproteinemia, decrease in average body mass index (BMI), glycemia and haemoglobin A1C (HbA1C) were observed. Hypertension did not improve during this period, which can be explained by transplant risk factors in the form of immunosuppressive drugs and chronic graft dysfunction. Conclusion A significant reduction in components of the metabolic syndrome after only one year of treatment was recorded, which should be the standard care of kidney transplant patients.

Rhabdomyolysis is a common cause of acute kidney injury, featuring muscle pain, weakness and dark urine and concurrent laboratory evidence of elevated muscle enzymes and myoglobinuria. Rhabdomyolysis is often seen in elderly and frail patients following prolonged immobilization, for example after a fall, but a variety of other causes are also well-described. What is unknown to most physicians dealing with such patients is the fascinating history of rhabdomyolysis. Cases of probable rhabdomyolysis have been reported since biblical times and during antiquity, often in the context of poisoning. Equally interesting is the link between rhabdomyolysis and armed conflict during the 20th century. Salient discoveries regarding the pathophysiology, diagnosis and treatment were made during the two world wars and in their aftermath. 'Haff disease', a form of rhabdomyolysis first described in 1920, has fascinated scientists and physicians alike, but the marine toxin causing it remains enigmatic even today. As a specialty, we have also learned a lot about the disease from 20th-century earthquakes, and networks of international help and cooperation have emerged. Finally, rhabdomyolysis has been described as a sequel to torture and similar forms of violence. Clinicians should be aware that rhabdomyolysis and the development of renal medicine are deeply intertwined with human history.

Introduction: Acute kidney injury (AKI) is one of the major public health issues with constantly increasing incidence, with epidemiology and outcomes that vary substantially across the world. Aim: Aim of our study was to determine epidemiological characteristics and causes of AKI and to provide a comparison of our findings with data from other low and middle income countries. Methods: This retrospective observational study conducted during an 18-month period included 84 patients. Data were collected from hospital information system and patients’ medical records. All data were analyzed using descriptive statistics. Results: More than two-thirds of patients were older than 56 years. Most cases of AKI (54,76%) were hospital-acquired and predominantly developed in intensive care units (32,14%). Dominant risk factor was underlying chronic kidney disease (48,81%) and chronic heart failure (45,24. In majority of patients (73,81%) were identified multiple factors that may have contributed to AKI: infection (90,48%), prerenal factors (77,38%), nephrotoxic agents (69,05%), and sepsis (28,57%). Multiple organ failure was identified in 94,05% of patients: cardiovascular (64,56%), respiratory (58,23%) and hematological (56,96%) system. Half of all patients were alive at last observation day. Leading cause of death was infection/sepsis (21,43%), followed by cancer (16,67%) and shock (14,28%). Conclusion: Data on AKI show great variation, but general picture of AKI resembles more that from high income countries. The need for dialysis and overall mortality remains high. This highlights the importance of early recognition of AKI, timely referral to nephrologist and need for national guidelines and standardized protocols for AKI.
