ABSTRACT Background. The creation of arteriovenous fistula (AVF) may retard chronic kidney disease progression in the general population. Conversely, the impact of AVF closure on renal function in kidney transplant recipients (KTRs) remains unknown. Methods. From 2007 to 2013, we retrospectively categorized 285 KTRs into three groups: no AVF (Group 0, n = 90), closed AVF (Group 1, n = 114) and left-open AVF (Group 2, n = 81). AVF closure occurred at 653 ± 441 days after kidney transplantation (KTx), with a thrombosis:ligation ratio of 19:95. Estimated glomerular filtration rate (eGFR) was determined using the Modification of Diet in Renal Disease equation. Linear mixed models calculated the slope and intercept of eGFR decline versus time, starting at 3 months post-KTx, with a median follow-up of 1807 days (95% confidence interval 1665–2028). Results. The eGFR slope was less in Group 1 (−0.081 mL/min/ month) compared with Group 0 (−0.183 mL/min/month; P = 0.03) or Group 2 (−0.164 mL/min/month; P = 0.09). Still, the eGFR slope significantly deteriorated after (−0.159 mL/min/month) versus before (0.038 mL/min/month) AVF closure (P= 0.03). Study periods before versus after AVF closure were balanced to a mean of 13.5 and 12.5 months, respectively, with at least 10 observations per patient (n = 99). Conclusions. In conclusion, a significant acceleration of eGFR decline is observed over the 12 months following the closure of a functioning AVF in KTRs. [less ▲]

Background Ectopic hormone-secreting pheochromocytomas <br />are rare; only case reports exist in the literature. This <br />condition has been linked with increased malignancy, <br />familial syndromes, and ACTH secretion. We wanted to <br />test these hypotheses and shed light on the nature of ectopic <br />hormone-secreting pheochromocytomas. <br />Methods This is a multicenter (francophone) observational <br />study. Inclusion was based upon abnormal preoperative <br />hormone tests in patients with pheochromocytoma <br />that normalized after removal of the tumor. Where <br />possible, immunohistochemistry was performed to confirm <br />that ectopic secretion came from the tumor. <br />Results Sixteen cases were found: nine female and seven <br />male patients. Median age was 50.5 (range 31–89) years. <br />Most presented with hypertension, diabetes, or cushingoid <br />features. Ten patients had specific symptoms from the <br />ectopic hormone secretion. Two had a familial syndrome. <br />Of eight patients with excess cortisol secretion, three died <br />as a result of the tumor resection: two had pheochromocytomas[ <br />15 cm and their associated cortisol hypersecretion <br />complicated their postoperative course. The other died <br />from a torn subhepatic vein. The 13 survivors did not <br />develop any evidence of malignancy during follow-up <br />(median 50 months). Symptoms from the ectopic secretion <br />resolved after removal of the tumor. Immunohistochemistry <br />was performed and was positive in eight tumors: five <br />ACTH, three calcitonins, and one VIP. <br />Conclusions Most pheochromocytomas with ectopic <br />secretion are neither malignant nor familial. Most ectopic <br />hormone-secreting pheochromocytoma cause hypercortisolemia. <br />Patients with a pheochromocytoma should be <br />worked up for ectopic hormones, because removal of the <br />pheochromocytoma resolves those symptoms. Associated <br />cortisol secretion needs careful attention. [less ▲]

Objective: Genetic disorders of calcium metabolism arise in a familial or sporadic setting. The calcium-sensing receptor (CaSR) plays a key role in maintaining calcium homeostasis and study of the CASR gene can be clinically useful in determining etiology and appropriate therapeutic approaches. We report two cases of novel CASR gene mutations that illustrate the varying clinical presentations and discuss these in terms of the current understanding of CaSR function. Patients and Methods: A 16 yr-old patient had mild hypercalcemia associated with low-normal urinary calcium excretion and normal-to-high parathyroid hormone (PTH) levels. Because of negative family history, familial hypocalciuric hypercalcemia (FHH) was originally excluded. The second patient was a 54 yr-old man with symptomatic hypocalcemia, hyperphosphatemia, low PTH, and mild hypercalciuria. Familial investigation revealed the same phenotype in the patient's sister. The coding region of the CaSR gene was sequenced in both probands and their available first-degree relatives. Results: The first patient had a novel heterozygous inactivating CASR mutation in exon 4, which predicted a p.A423K change; genetic analysis was negative in the parents. The second patient had a novel heterozygous activating CASR mutation in exon 6, which predicted a p.E556K change; the affected sister of the proband was also positive. Conclusions: We reported two novel heterozygous mutations of the CASR gene, an inactivating mutation in exon 4 and the first activating mutation reported to date in exon 6. These cases illustrate the importance of genetic testing of CASR gene to aid correct diagnosis and to assist in clinical management. [less ▲]
