Kidney injury (defined as the presence of albuminuria, proteinuria, glycosuria [without hyperglycemia], hematuria, and/or renal hypophosphatemia) is an emerging problem in human immunodeficiency virus (HIV)-infected patients, although few data are available on the role of protease inhibitors (PIs)
BACKGROUND
Kidney disease is an important complication in HIV infected people, and this may be related to infection or antiretroviral therapy (ART). Our aim is to assess renal function in HIV infected paediatric patients, who may be particularly affected and are likely to take ART for longer than
BACKGROUND
Cobicistat (COBI) is a pharmacoenhancer and one of the components of ECF/TDF (elvitegravir/cobicistat/emtricitabine/tenofovir DF), which is approved in treatment-naïve HIV patients with creatinine clearance (CrCl) ≥70 mL/min. Study 118 assessed the renal safety of COBI-containing regimens
To better evaluate the renal safety profile of tenofovir, we performed a retrospective study of HIV-infected antiretroviral-naïve patients starting a first antiretroviral therapy between July 2004 and July 2008, and followed-up for 24 months. The glomerular filtration rate (GFR) was calculated using
BACKGROUND
Cobicistat, a component of stribild (STB), is known to inhibit renal creatinine secretion. A detailed analysis of the renal safety profile of STB in two Phase 3b switch studies of virologically-suppressed individuals on stable therapy: STRATEGY(S)-PI (STB vs a RTV-boosted protease
Hyp-mice exhibit abnormal regulation of 25-hydroxyvitamin D [25(OH)D]-1alpha-hydroxylase activity. Previous observations suggest such aberrant modulation is posttranscriptional. To investigate this possibility further, we examined whether hyp-mice manifest abnormal translation of
Proteolytic enzymes mediate the activation or inactivation of many physiologic and pathologic processes. The PHEX gene (Phosphate-regulating gene with homologies to endopeptidase on the X chromosome) encodes a metallopeptidase, which is mutated in patients with a prevalent form (1:20,000) of
We present an HIV-infected woman in whom antiretroviral treatment with tenofovir disoproxil fumarate (TDF) induced severe skeletal pain, synovial effusions and multiple fractures secondary to a Fanconi syndrome with hypophosphatemia and osteomalacia. TDF interferes with the replication of
BACKGROUND
HIV-infected patients may develop a variety of underreported metabolic abnormalities that may be classified into HIVAN, specific HIV abnormalities, coincidental renal disorders and anti-retroviral-treatment-induced side effects.
METHODS
Our descriptive cross-sectional study evaluates the
Missense mutations in fibroblast growth factor 23 (FGF23) are the cause of autosomal dominant hypophosphatemic rickets (ADHR). The mutations (R176Q, R179W, and R179Q) replace Arg residues within a subtilisin-like proprotein convertase (SPC) cleavage site (RXXR motif), leading to protease resistance
Klotho has profound effects on phosphate metabolism, but the mechanisms of how Klotho affects phosphate homeostasis is unknown. We detected Klotho in the proximal tubule cell, brush border, and urinary lumen, where phosphate homeostasis resides. Increasing Klotho in the kidney and urine chronically
Background: Renal abnormalities in HIV infected children may be due to the HIV infection or treatment among other factors. Tenofovir disoproxil fumarate (TDF) is associated with proximal renal tubular dysfunction, proteinuria and decrease
Fibroblast growth factor 23 (FGF23) is a recently characterized protein likely involved in the regulation of serum phosphate homeostasis. Increased circulating levels of FGF23 have been reported in patients with renal phosphate-wasting disorders, but it is unclear whether FGF23 is the direct
Matrix extracellular phosphoglycoprotein (MEPE) is expressed exclusively in osteoblasts, osteocytes and odontoblasts with markedly elevated expression found in X-linked hypophosphatemic rickets (Hyp) osteoblasts and in oncogenic hypophosphatemic osteomalacia (OHO) tumors. Because these syndromes are
