Abstract
Chronic lymphocytic leukemia (CLL) is a lymphoproliferative disorder often diagnosed after incidental finding of leukocytosis. Renal involvement is usually clinically silent. Symptomatic renal impairment due to CLL/small lymphocytic lymphoma (SLL) cell infiltration in the kidney tissue is uncommon, and acute kidney injury (AKI) as a presenting feature is rare. In this case report, we describe the case of a patient with AKI caused by CLL/SLL infiltration as a presenting feature. Our report highlights the possibility of kidney injury as the first evident symptom of CLL/SLL. Kidney biopsy is the mainstay in these cases in order to establish a diagnosis. Treatment with zanubrutinib resulted in improved kidney function.

Abstract
Aims: Chronic lymphocytic leukemia (CLL) involves the proliferation and increase of B-lymphocytes in the peripheral blood, bone marrow and lymphoid organs. This study evaluated the microRNAs miR-197, miR-26a and miR-27a as potential biomarkers for CLL. Patients & Methods: Eighty-two patients with CLL and 62 control subjects (CT) were investigated for these targets, using quantitative PCR (qPCR). Results: A significant reduction of all microRNAs was observed in CLL compared to the controls (p < 0.001). Significant negative correlations were observed for the clinical staging groups. After adjusting for multiple logistic regression analysis, miR-197 and miR-26a remained as possible independent risk factors related to the CLL. Conclusions: Our data indicated good performance of this microRNAs as potential biomarkers in CLL.

Abstract
Classical CRAB features (hypercalcaemia, renal failure, anaemia, osteolytic lesions) have been traditionally defined in patients with plasma cell dyscrasia. But these can be rare and uncommon presentations of other chronic lymphoproliferative disorders (CLPD). The pathophysiological basis of CRAB features in other CLPD need to be explored further for better outcomes and therapeutic interventions. These can present a diagnostic dilemma and requires extensive workup to rule out coexisting malignancy and myeloma. Here, we report an unusual case of B CLPD in a middle-aged male who presented with classical CRAB features along with a brief literature review. After detailed investigations, he was diagnosed as chronic lymphocytic leukaemia, without any second malignancy and responded well to ibrutinib-based therapy.

Abstract
Key genes in chronic lymphocytic leukemia (CLL) were investigated through systematically tracking the dysregulated modules from protein-protein interaction (PPI) networks. Microarray data of normal subjects and CLL patients recruited from ArrayExpress database were applied to extract differentially expressed genes (DEGs). Additionally, we re-weighted the PPI network of normal and CLL conditions by means of Pearsons correlation coefficient (PCC). Furthermore, clique-merging method was applied to extract the modules and then the altered modules were screened out. The intersection genes were selected from miss and add genes in the altered modules. The common genes were screened from the intersection genes and DEGs in CLL. A total of 734 DEGs were screened by statistical analysis. In this investigation, there were 1,805 and 703 modules in normal as well as disease PPI network. In addition, 875 altered modules were obtained which included 145 miss genes, 353 add genes and 85 intersection genes. Finally, in-depth analysis revealed 9 mutual genes between the intersection genes and DEGs in CLL. Our analysis revealed several key genes associated with CLL by systematically tracking the dysregulated modules, which might be candidate targets for diagnosis and management of CLL.
