Cellular immunity has been implicated in the pathogenesis of Crohn's disease. In the present work, we have studied T-lymphocytes subsets in peripheral blood and intestinal mucosa of eight patients with active disease, using monoclonal antibodies. Intraepithelial and lamina propia OKT-3 +ve cells were significantly lower than in peripheral blood (p less than 0.001). We have found an increase of B cells and OKT-8 +ve cells in intestinal mucosa with a significant decrease in helper/suppressor ratio. These findings are in accordance with a high suppressor-cytotoxic function in patients with active diseases.

Immune checkpoint inhibitors have improved the treatment of metastatic renal cell carcinoma (RCC), with the combination of nivolumab (NIVO) and ipilimumab (IPI) showing promising results. However, not all patients benefit from these therapies, emphasizing the need for reliable, easily assessable biomarkers. This multicenter study involved 116 advanced RCC patients treated with NIVO + IPI across nine oncology centers in Poland.

The pathogenesis of Lewy body diseases (LBDs), including Parkinson's disease (PD), involves α-synuclein (α-Syn) aggregation that originates in peripheral organs and spreads to the brain. PD incidence is increased in individuals with chronic renal failure, but the underlying mechanisms remain unknown. Here we observed α-Syn deposits in the kidneys of patients with LBDs and in the kidney and central nervous system of individuals with end-stage renal disease without documented LBDs.

Fluid biomarkers play important roles in many aspects of neurodegenerative diseases, such as Huntington's disease (HD). However, a main question relates to how well levels of biomarkers measured in CSF are correlated with those measured in peripheral fluids, such as blood or saliva. In this study, we quantified levels of four neurodegenerative disease-related proteins, neurofilament light (NfL), total tau (t-tau), glial fibrillary acidic protein (GFAP) and YKL-40 in matched CSF, plasma and saliva samples from Huntingtin (HTT) gene-positive individuals (n = 21) using electrochemiluminescence assays.

Nephrotic syndrome is characterised by heavy proteinuria secondary to glomerular injury. It is an uncommon but serious complication of allogeneic haematopoietic stem cell transplant (HSCT), but rarely reported after autologous HSCT. Here, we report the case of a man in his mid-20s who presented with significant peripheral oedema 2 months after autologous HSCT for Hodgkin lymphoma.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.
