چکیده
The authors report two cases of polyomavirus infection in renal allograft recipients. In the first case, a stable patient presented with deterioration of renal function, worsening hypertension and weight gain following removal of ureteral stent placed routinely at the time of surgery. Ultrasound examination and radiology studies revealed hydronephrosis due to ureteral stenosis. A new ureteral stent was placed, but renal function did not improve. Urinary cytology revealed the presence of decoy cells and polyomavirus was detected in blood and urine by qualitative polymerase chain reaction. Renal biopsy findings were consistent with polyomavirus -associated nephropathy. In the second case, leucopaenia was detected in an asymptomatic patient 6 months after transplantation. Mycophenolate mophetil dosage was reduced but renal allograft function deteriorated, and a kidney biopsy revealed polyomavirus -associated nephropathy, also with SV40 positive cells.

Renal Tubular Acidosis (RTA) is a clinical syndrome characterised by metabolic acidosis secondary to a disorder in renal acidification. The acidification may be manifested by a defect in the renal tubular reabsorption of bicarbonate and/or urinary excretion of hydrogen ion1 -3. In terms of clinical and physiopathological aspects this disease can be classified into three groups: distal RTA or ty...

The clinical relevance: The assessment of the antigenicity of an injectable molecule for the human organism requires human patient sera due to the inherent variability of antibodies from person to person, and the inherent variation of bioactivity of antibodies within a single individual. Antibodies produced experimentally in animals give little information with regard to clinical effects of the...

We describe the case of a renal transplant recipient who presented with malaise, dry cough, severe weight loss, abdominal pain and watery diarrhoea. The laboratory workup revealed anaemia and elevated C reactive protein. Chest X-ray showed bilateral reticulonodular infiltrates, and computed tomography scan of the chest and abdomen revealed diffuse thickening of the interand intralobular septs, ...

We present a 57-year-old male chronic haemodialysis patient with a giant umbilical hernia. After two months on dialysis, incarceration of the hernia with partial intestinal obstruction occurred, and this led to severe hypoproteinaemia secondary to protein-losing enteropathy, caused by increased lymphatic pressure. These problems were resolved following surgical repair of the hernia. There are f...

We present the case of a fourteen-year-old girl who complained of depression, weight gain and hirsutism. She was obese, apathetic and had poverty of movements. She had anaemia, deteriorated renal function and elevated hepatic enzymes. Free T3 was <0.19 pg/mL and TSH 276 UI/mL. Antithyroglobulin and antimicrosome antibodies were positive, and the thyroid ultrasonography revealed thyroiditis. She...
