The peripheral lymphocytes of 50 cases of human immunodeficiency virus (HIV) infection (13 of acquired immune deficiency syndrome (AIDS), 17 of AIDS related complex (ARC), and 20 healthy carriers) were studied immunoultrastructurally. The prevalence of "tubuloreticular structures" and "tubular confronting cisternae" increased with the progression of the disease. Numerous tubular confronting cis...
The urinary sediment was examined by light microscopy in 65 consecutive inpatients with renal insufficiency (not due to pre- or postrenal factors) referred to a nephrology consult service for evaluation. In the 60 patients in whom a single diagnosis was reached, the sediments of 34 (57%) contained an easily recognized cell, which we have called the "bubble cell". These cells were bizarre, large...
The renal tubule is responsible for the reabsorption of more than 99% of the water and sodium in the glomerular ultrafiltrate. Congenital or acquired tubular dysfunction can therefore readily cause profound electrolyte and volume disturbance. The tubule also has to regulate acid– base balance, mineral homoeostasis, and the excretion of organic anions and drugs. To fulfil these functions, a larg...
In the past decade our understanding of the etiology and pathophysiology of Gitelman syndrome, an autosomal recessive salt-losing tubular disorder with secondary hypokalemia, has increased considerably through the achievements of molecular genetics and cell physiology. In this short review, I will summarize the most recent data on the clinical and biochemical phenotype, the molecular causes, an...
Steroid-resistant nephrotic syndrome (SRNS) causes 15% of chronic kidney disease (CKD). Here we show that recessive mutations in FAT1 cause a distinct renal disease entity in four families with a combination of SRNS, tubular ectasia, haematuria and facultative neurological involvement. Loss of FAT1 results in decreased cell adhesion and migration in fibroblasts and podocytes and the decreased m...
An apparently autosomal recessive syndrome of congenital renal tubular dysplasia and skull ossification defects is described in five infants from two separate, consanguineous, Pakistani Muslim kindreds. The clinical, pathological, and radiological features are similar to the phenotype associated with fetal exposure to angiotensin converting enzyme (ACE) inhibitors: intrauterine growth retardati...
In the past decade major advances in our understanding of renal tubular hydrogen ion secretion and bicarbonate reabsorption have provided new insight into the pathophysiology of renal tubular acidosis. Thus "fragment to fragment clings" and the number of disorders categorized within the syndrome grows, until we have come to know and name four types, with many subtypes. We hope this new perspect...
The discovery of a case of renal tubular acidosis and fibrosing alveolitis led to the investigation of 19 further patients. Abnormal pulmonary function tests were found in a further four patients with overt renal tubular acidosis and in four out of eight patients with "incomplete" renal tubular acidosis. The response to an ammonium chloride test in seven patients with cryptogenic fibrosing alve...
Abstract A 66-year-old woman showing renal dysfunction with elevated serum alkaline phosphatase and anti-SS-A antibody was admitted. A labial salivary gland biopsy showing infiltration of mononuclear cells and positive anti-SS-A antibody with sicca symptoms led to a diagnosis of primary Sjögren’s syndrome (SS). Fanconi’s syndrome was diagnosed by renal tubular acidosis along with renal glucosur...
Signaling through the store-operated Ca(2+) release-activated Ca(2+) (CRAC) channel regulates critical cellular functions, including gene expression, cell growth and differentiation, and Ca(2+) homeostasis. Loss-of-function mutations in the CRAC channel pore-forming protein ORAI1 or the Ca(2+) sensing protein stromal interaction molecule 1 (STIM1) result in severe immune dysfunction and nonprog...
