Treatment of Adrenocorticotropin-Dependent Cushing’s Syndrome: A Consensus Statement

Abstract: Objective: Our objective was to evaluate the published literature and reach a consensus on the treatment of patients with ACTH-dependent Cushing’s syndrome, because there is no recent consensus on the management of this rare disorder. Participants: Thirty-two leading endocrinologists, clinicians, and neurosurgeons with specific expertise in the management of ACTH-dependent Cushing’s syndrome representing nine countries were chosen to address 1) criteria for cure and remission of this disorder, 2) surgical treatment of Cushing’s disease, 3) therapeutic options in the event of persistent disease after transsphenoidal surgery, 4) medical therapy of Cushing’s disease, and 5) management of ectopic ACTH syndrome, Nelson’s syndrome, and special patient populations. Evidence: Participants presented published scientific data, which formed the basis of the recommendations. Opinion shared by a majority of experts was used where strong evidence was lacking. Consensus Process: Participants met for 2 d, during which th...

The codon 620 tryptophan allele of the lymphoid tyrosine phosphatase (LYP) gene is a major determinant of Graves' disease.

Abstract: The lymphoid tyrosine phosphatase (LYP), encoded by the protein tyrosine phosphatase-22 (PTPN22) gene, is a powerful inhibitor of T cell activation. Recently, a single nucleotide polymorphism (SNP), encoding a functional arginine to tryptophan residue change at LYP codon 620 has been shown to be associated with type 1 diabetes and other autoimmune disorders. We have used a PCR-restriction fragment (XcmI) assay to examine genotypes at the codon 620 polymorphism in 549 unrelated probands with Graves' disease, 104 unrelated subjects with autoimmune Addison's disease and 429 controls. The T nucleotide at the SNP, encoding the tryptophan 620 residue, was present in 151 of 1098 (13.8%) Graves' disease alleles compared to 67 of 858 (7.8%) control alleles (chi(2) = 17.2, p = 3.4 x 10(-5)' odds ratio = 1.88, 5-95% confidence intervals [CI] 1.39 to 2.55). Similarly, the T nucleotide at the codon 620 SNP was present in 26 of 208 (12.5%) Addison's disease alleles vs 7.8% of controls (chi(2) = 4.63, p = 0.031; odds ratio = 1.69, 5-95% CI 1.04 to 2.73). These data suggest that this LYP polymorphism is a susceptibility allele for Graves' disease with a major effect, and which is likely to have a role in many other autoimmune conditions.

Polycyclic Aromatic Hydrocarbons: Sources, Toxicity, and Remediation Approaches.

Abstract: Polycyclic aromatic hydrocarbons (PAHs) are widespread across the globe mainly due to long-term anthropogenic sources of pollution. The inherent properties of PAHs such as heterocyclic aromatic ring structures, hydrophobicity, and thermostability have made them recalcitrant and highly persistent in the environment. PAH pollutants have been determined to be highly toxic, mutagenic, carcinogenic, teratogenic, and immunotoxicogenic to various life forms. Therefore, this review discusses the primary sources of PAH emissions, exposure routes, and toxic effects on humans, in particular. This review briefly summarizes the physical and chemical PAH remediation approaches such as membrane filtration, soil washing, adsorption, electrokinetic, thermal, oxidation, and photocatalytic treatments. This review provides a detailed systematic compilation of the eco-friendly biological treatment solutions for remediation of PAHs such as microbial remediation approaches using bacteria, archaea, fungi, algae, and co-cultures. In situ and ex situ biological treatments such as land farming, biostimulation, bioaugmentation, phytoremediation, bioreactor, and vermiremediation approaches are discussed in detail, and a summary of the factors affecting and limiting PAH bioremediation is also discussed. An overview of emerging technologies employing multi-process combinatorial treatment approaches is given, and newer concepts on generation of value-added by-products during PAH remediation are highlighted in this review.
