When a recurrence is suspected after CA or RFA, different options are available. This review has highlighted that active surveillance, reablation, and surgery (usually radical nephrectomy) are all viable options for the management of a failed ablative procedure.
Each grading system performs well but the predictive accuracy of Fuhrman grade is statistically superior to that of nucleolar grade and only Fuhrman grade provides independent prognostic information on patients with papillary renal cell carcinoma. Thus, Fuhrman grade should be the standard grading system for papillary renal cell carcinoma.
The adaptor protein Src homology 2 (SH2) domain containing leukocyte protein of 76 kDa (SLP-76) is critical for multiple aspects of T cell development and function. Through its protein-binding domains, SLP-76 serves as a platform for the assembly of multiple enzymes and adaptor proteins that function together to activate second messengers required for TCR signal propagation. The N-terminus of SLP-76, which contains three tyrosines that serve as docking sites for SH2 domain-containing proteins, and the central proline-rich region of SLP-76 have been well studied and are known to be important for both thymocyte selection and activation of peripheral T cells. Less is known about the function of the C-terminal SH2 domain of SLP-76. This region inducibly associates with the adhesion- and degranulation-promoting adaptor protein (ADAP) and hematopoietic progenitor kinase 1 (HPK1). Combining regulated deletion of endogenous SLP-76 with transgenic expression of a SLP-76 SH2 domain mutant, we demonstrate that the SLP-76 SH2 domain is required for peripheral T cell activation and positive selection of thymocytes, a function not previously attributed to this region. This domain is also important for T cell proliferation, IL-2 production and phosphorylation of protein kinase D (PKD) and IκB. ADAP-deficient T cells display similar, but in some cases less severe, defects despite phosphorylation of a negative regulatory site on SLP-76 by HPK1, a function that is lost in SLP-76 SH2 domain mutant T cells.
BackgroundPatients with primary immunodeficiency disease (PIDD) and antibody deficiency require lifelong immunoglobulin replacement therapy. While both subcutaneous immunoglobulin (SCIG) and intravenous immunoglobulin (IVIG) replacement therapy are effective in preventing infection, patients with PIDD still experience worse health-related quality of life (hrQOL) outcomes.ObjectiveAssess differences in hrQOL for PIDD patients receiving home SCIG versus IVIG.MethodsSF-36 surveys were administered by a specialty pharmacy to 630 PIDD patients receiving home SCIG and IVIG at baseline and then every 3 months between 2014 and 2016. Results were analyzed using two-sample t tests and linear mixed effects model. Analysis was repeated for different age categories and trended over time.ResultsPatients receiving SCIG reported statistically significant higher energy fatigue scores (+ 9 points, p < 0.001) but lower perceived role limitations due to physical health scores (− 14 points, p < 0.001). These differences were only observed in patients > 36 years of age. There were no differences in the composite SF-36 score for patients receiving SCIG versus IVIG (+ 1, p = 0.66). Immunoglobulin-naïve patients all improved their hrQOL, but a larger improvement was seen in those initiating SCIG versus IVIG.ConclusionPatients with PIDD on home IVIG versus SCIG have similar composite hrQOL scores as measured by the SF-36. In the adult population, initiating immunoglobulin replacement with SCIG may result in more hrQOL improvement compared with IVIG, although personal preferences should also be considered.Clinical ImplicationsPatients with PIDD on home IVIG versus SCIG have similar composite health-related quality of life scores as measured by the SF-36.Capsule SummaryPatients with primary immune-deficiency on home IVIG versus SCIG have similar composite health-related quality of life scores as measured by the SF-36. Personal preferences are important in deciding whether to treat with IVIG or SCIG.Electronic supplementary materialThe online version of this article (10.1007/s10875-019-00705-5) contains supplementary material, which is available to authorized users.
