Measuring quality of life in patients with kidney stone disease: is it the future in endourology?

PURPOSE OF REVIEW

Kidney stone disease is recognized to negatively impact quality of life. This pertains to acute episodes, surgical interventions and even during asymptomatic periods. Over time there has been increased attention towards assessing this subjective parameter, including as a determinant of treatment success. Our aim was to evaluate the current status and emerging trends in this field.

RECENT FINDINGS

Patient groups most affected appear to be recurrent stone formers, cystine stone formers, women, younger populations, non-Caucasians and low-income populations. Several stone specific patient reported outcome measures are now available of which, WISQol has been implemented the most in clinical research studies. More invasive interventions such as percutaneous nephrolithotomy impede quality of life to greater extent than alternatives such as shockwave lithotripsy.

SUMMARY

There are certain patient groups who are more vulnerable to the negative impact of kidney stone disease on their quality of life. Urologists can improve patient care by recognizing these particular populations as well as by implemented patient reported outcome measures in their routine clinical practice and when performing research.

Frequency of JAK2V617F, MPL and CALR driver mutations and associated clinical characteristics in a Norwegian patient cohort with myeloproliferative neoplasms

Myeloproliferative neoplasms are hematological disorders characterized by increased production in one or more myeloid cell lines, associated with driver mutations in JAK2-, MPL- and CALR-genes. The aims of this study were to investigate the prevalence of these driver mutations in a Norwegian patient cohort with myeloproliferative neoplasms, and to assess whether the different mutations were associated with different clinical presentation and natural history.Results from 820 patients in whom analysis for JAK2V617F-, CALR- and MPL had been performed at Haukeland University Hospital in the period 2014-2019 were retrieved and analyzed together with clinical variables related to diagnosis, hematological blood parameters and complications, obtained from patient records.We identified 182 cases of myeloproliferative neoplasms: 78 with JAK2V617F, 28 with CALR-mutations, two with MPL-mutations and 23 cases without a driver mutation. There was a lower prevalence of JAK2V617F mutation than expected in the polycythemia vera group, likely related to overdiagnosis. In patients with essential thrombocytosis, we found significantly higher levels of hemoglobin and erythrocyte volume fraction for JAK2V617F-mutated disease, and significantly higher levels of platelets and lactate dehydrogenase for CALR-mutated disease. Patients with JAK2V617F-mutated primary myelofibrosis had significantly higher levels of hemoglobin, and there was an increased number of smokers or former smokers in this group compared to patients with CALR-mutations.Except for a lower prevalence of JAK2V617F-mutation in polycythemia vera, the mutational distribution in our patient cohort was similar to previous findings in other populations. The novel finding of a higher prevalence of smokers in JAK2V617F-mutated primary myelofibrosis warrants further investigation.

Weight gain during treatment course of allogenic hematopoietic stem cell transplantation in patients with hematological malignancies affects treatment outcome

BACKGROUND AIMS

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective treatment for patients with hematological malignancies; however, allo-HSCT does not come without the cost of treatment-related morbidity and mortality. Early detection of risk factors could be helpful in identifying patients who could benefit from early interventions. Many patients gain weight during the allo-HSCT treatment, although little is known about the impact of weight gain.

METHODS

Weight gain in 146 consecutively enrolled adult patients undergoing allo-HSCT was explored.

RESULTS

In total, 141 patients (97%) gained weight along the course of allo-HSCT. Median weight increase was 4.8 kg (range 0.0-16.1 kg), with median increase in body weight 6.5% (range 0.0%-30.8%). Maximum weight increase was observed at day +7 (range day -8, +44). Weight gain was associated with increased incidence of acute graft-versus-host disease. Patients with weight gain >10% had a significantly greater 5-year mortality compared with those with lower weight gain (P = 0.031, rank sum test).

CONCLUSIONS

Weight gain is a simple variable with the ability to provide prognostic information for patients undergoing allo-HSCT.

Cytokine Release Syndrome in the Immunotherapy of Hematological Malignancies: The Biology behind and Possible Clinical Consequences

Cytokine release syndrome (CRS) is an acute systemic inflammatory syndrome characterized by fever and multiple organ dysfunction associated with (i) chimeric antigen receptor (CAR)-T cell therapy, (ii) therapeutic antibodies, and (iii) haploidentical allogeneic stem cell transplantation (haplo-allo-HSCT). Severe CRS can be life-threatening in some cases and requires prompt management of those toxicities and is still a great challenge for physicians. The pathophysiology of CRS is still not fully understood, which also applies to the identifications of predictive biomarkers that can forecast these features in advance. However, a broad range of cytokines are involved in the dynamics of CRS. Treatment approaches include both broad spectrum of immunosuppressant, such as corticosteroids, as well as more specific inhibition of cytokine release. In the present manuscript we will try to review an update regarding pathophysiology, etiology, diagnostics, and therapeutic options for this serious complication.
