Direct stimulation of the antitumor activity of immune system through checkpoint inhibitors (ICIs) has demonstrated efficacy in the treatment of different cancer types. The activity of these antibodies takes place in the immunological synapse blocking the binding of the negative immunoregulatory proteins, thus leading to the finalization of the immune response. Despite having a favorable toxicity profile, its mechanism of action impedes the negative regulation of the immune activity which can potentially favor autoimmune attacks to normal tissues...

Microvascular injury is an important factor in renal allograft survival. Repeated episodes of endothelial injury from chronic antibody-mediated rejection typically manifest at the ultrastructural level as circumferential multilayering of remodeled glomerular basement membrane material and peritubular capillary basal lamina. In contrast to this typical pattern of microvascular injury, a renal transplantation case is presented in which focally dilated and multilayered segments of peritubular capillary basal lamina bearing lipid droplets were interspersed with ultrastructurally normal unilayered segments of basal lamina devoid of lipid droplets...

Filariasis is traditionally diagnosed on finding microfilaria in peripheral blood smear and in cases of occult filariasis by immunological tests. Clinically, it presents with a wide range of symptoms and signs. We present two cases of filariasis presenting with renal symptoms warranting kidney biopsy. Histopathology of both revealed microfilaria in the glomerular capillary loop. First case was a 23-year-old male who presented with complaints of passage of milky urine. Second case was a 36-year-old female patient who presented with complaints of gross hematuria...

BACKGROUND: The management of metastatic Renal Cell Carcinoma (RCC) has changed dramatically in the last 20 years, and the role of surgery in the immunotherapy's era is under debate. Metastatic lesions interesting pancreas are infrequent, but those harbouring from RCC have an high incidence. If metachronous resections are not rare, synchronous resection of primary RCC and its pancreatic metastasis is uncommonly reported, and accounts for a bad prognosis. CASE PRESENTATION: We report the case of a 68 years old woman, who presented hematuria at hospital incoming, with radiological appearance of a 13 cm left renal mass, with a 2...

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and lethal cancers with very few available treatments. For many decades, gemcitabine was the only treatment for patients with PDAC. A recent attempt to improve patient survival by combining this chemotherapy with FOLFIRINOX and nab-paclitaxel failed and instead resulted in increased toxicity. Novel therapies are urgently required to improve PDAC patient survival. New treatments in other cancers such as melanoma, non-small-cell lung cancer, and renal cancer have emerged, based on immunotherapy targeting the immune checkpoints cytotoxic T-lymphocyte-associated antigen 4 or programmed death 1 ligand...

BACKGROUND: Surgical complications following kidney transplantation compromise immediate graft survival. However, the role of early surgical complications in the impairment of long-term survival is not completely established due to various other influences, such as patient comorbidities. The purpose of this study was to characterize the impact of surgical complications and overlapping patient comorbidities on graft function and survival after living donor kidney transplantation (LDKT)...

Renal cell carcinoma (RCC) is the most common tumor originating from the kidneys. In comparison to other solid tumors, RCC is poorly sensitive to conventional therapeutic modalities. As such, metastatic RCC (mRCC) continues to be associated with high rates of morbidity and mortality. Targeted agents have shown remarkable progress in RCC management with improved patients' outcomes, but rarely induce complete response and patients develop resistance to therapy eventually. However, it is well known that RCC represents one of the most immunogenic cancers and is able to evoke immune response naturally, thus prompted the emergence of several immunotherapeutic strategies in the management of RCC with variable degrees of success...

Autoantibodies against double-stranded DNA (dsDNA) were first described >60 years ago and although they are still one of the most clinically relevant autoantibodies, test results may be more challenging to interpret compared to other autoantibody tests. They are a serological hallmark of systemic lupus erythematosus (SLE) and are included in both the American College of Rheumatology (ACR) and the Systemic Lupus International Collaborating Clinics (SLICC) classification criteria for SLE. Furthermore, anti-dsDNA antibodies (a-dsDNA) have been shown to associate with SLE disease activity and coincide with renal involvement...

BACKGROUND: Graft loss in intestinal transplantation (ITx) is close to 25% in the first year and 50% at 5-year post-transplantation. Although technically and immunologically challenging, intestinal retransplantation is now the 4th most common indication for ITx. METHODS: The aim of this study is to review and compare the outcomes of intestinal retransplantation with primary ITx, which included isolated ITx, modified multivisceral transplantation (mMVTx), and full MVTx, between 2003-2014 at Indiana University...

Introduction: Segmental arterial mediolysis (SAM) is a rare, non-atherosclerotic, non-inflammatory vascular disease mostly affecting medium to large sized abdominal arteries which may cause aneurysms, stenosis, and haemorrhage. Report: A case is reported of a patient with SAM affecting the renal arteries bilaterally, where the diagnosis was made by excluding other inflammatory, immunological, and infectious mimickers. Discussion: As SAM carries a significant mortality and morbidity from end organ ischaemia, infarction, or haemorrhage, it should be considered in any patient presenting with abdominal pain...

Atypical haemolytic uremic syndrome is a disease caused by complement regulation abnormalities that generally progresses to chronic end-stage renal disease with a high rate of recurrence in kidney transplantation and a high risk of graft loss. Anti-complement therapy has improved the prognosis of these patients, achieving disease remission in most cases, increasing the likelihood of a successful kidney transplant and increasing patient and graft survival. Drugs with low risk of induction of thrombotic microangiopathies such as belatacept and mycophenolate have also been used with satisfactory results...

Metastatic colorectal cancer still remains an essentially non curable disease. However, with advances in chemotherapeutic and personalizing therapeutic approaches with the incorporation of targeted therapy such as anti-EGFR and anti-VEGF agents survival associated with metastatic colorectal cancer has certainly improved over the last two decades. Patients who are not amenable to surgery median survival remain approximately 2 to 3 years. In an attempt to improve prognostic outcome over the last decade research has focused on therapeutic options geared towards harnessing the immune system with success observed with the use of immune checkpoint inhibitors in the realm of a number of solid tumors including lung and renal cancer...
