The type of proteinuria and renal selectivity of glycosyl albumin has been evaluated in seven diabetic patients at the onset of plasma hyperosmolar state and after complete fluid replacement. The main feature of all patients was a marked increase in urinary excretion of beta 2-microglobulin, which promptly returned to normal after the correction of the fluid disequilibrium. This indicates that a reversible tubular injury is the first symptom of the dehydration process in diabetic patients with plasma hyperosmolality.

We describe a patient with systemic lupus erythematosus (SLE) with lupus psychosis, who showed prolonged consciousness disturbance due to hyperosmolality. A 51-year-old Japanese woman with SLE was admitted to our hospital for the evaluation and treatment of consciousness disturbance on March 5, 1994. She had not been given prednisolone since 1984, and had been depressive since January 1994. She was diagnosed as active SLE with lupus psychosis due to the presence of thrombocytopenia, proteinuria, positive anti-nuclear antibody (x10,240) as well as the elevation of cerebrospinal fluid (CSF) IL-6 level. A treatment with methylprednisolone (mPL) 100 mg/day was started along with 2 courses of steroid pulse therapy (mPL 1 g/day for 3 consecutive days). She recovered partially from the central nervous system manifestations with a decrease in CSF IL-6 level 2 weeks after this treatment. However, her consciousness level was exacerbated again thereafter. Blood examination disclosed the elevation of plasma osmolality (319 mOsm/kg) with poor responses of plasma antidiuretic hormone (4.6 pg/ml). She died from systemic aspergillosis on April 26, 1994. Pathological examination on autopsy showed no abnormality in hypothalamus and pituitary gland. It is suggested that this patient was complicated with lupus psychosis as well as hyporesponsiveness of osmoreceptor. Rheumatologists should be aware of this complication in patients with CNS lupus as a possible cause for intractable CNS manifestations.

Neonatal renal vein thrombosis (RVT) is associated with potentially serious morbidities. Almost 80% of cases of RVT present within the first postnatal month. The most common risk factors for RVT are birth asphyxia/ in utero fetal distress, being the infant of a diabetic mother, volume contraction and coagulation abnormalities. Thrombus formation may be initiated by vascular injury, diminished vascular flow, increased blood viscosity, hyperosmolality or underlying thrombophilia. The classic triad of RVT includes gross hematuria, flank mass (unilateral or bilateral enlargement of kidneys) and thrombocytopenia. Laboratory tests may reveal hematuria, proteinuria, polycythemia, hemolytic anemia, thrombocytopenia and possibly acute kidney injury. The etiology for a hypercoagulable state should be investigated. Renal ultrasound with Doppler may show increased size of the affected kidney, increased echogenicity and loss of corticomedullary differentiation. Renal venography remains the gold standard for the diagnosis of RVT. Other causes of renal enlargement must be considered. Supportive treatment includes correction of fluid and electrolyte disturbances and treatment of infection and underlying pathophysiologic abnormalities. Use of unfractionated heparin (UFH) or low molecular weight heparin (LMWH) should be considered if there is evidence of disseminated intravascular coagulation. Conventional anticoagulants may attenuate hypercoagulability and decrease the risk for thrombus progression and embolism. Surgery is rarely indicated unless there is bilateral involvement with involvement of the IVC. RVT carries the risk of hypertension and chronic kidney disease.
