Diagnosis of disease in renal allografts: correlation between ultrasound and histology

Ultrasound was compared with histology in 66 cases to assess the accuracy of sonography in demonstrating abnormality in renal allografts. Patients with suspected acute, chronic or acute and chronic rejection, acute tubular necrosis and glomerulonephritis in the transplant kidney were included in the study. It was noted in this trial that ultrasound is less accurate at demonstrating abnormality in the grafted kidney than has been suggested previously in the literature. It was concluded that, where doubt exists, even when ultrasound examination is normal, biopsy should be considered.     

Methylprednisolone in patients with membranous nephropathy and declining renal function

Fifteen consecutive patients aged 24 to 70 years, with membranous nephropathy and a progressive decline in renal function, were treated with methylprednisolone, 1 g intravenously daily for five days, followed immediately by a tapering dose of oral prednisolone. Plasma creatinine levels fell by a mean of 46 per cent (range 21-65). In 10 patients the beneficial effect was sustained, but in three it had reversed by six months. In the other two patients the progressive decline of renal function was not influenced. These observations suggest that many patients with membranous nephropathy and declining renal function could benefit from intervention with high dose steroids.

Evaluation of direct agglutination test (DAT) and ELISA for serodiagnosis of visceral leishmaniasis in India

The direct agglutination test (DAT) and the enzyme-linked immunosorbent assay (ELISA) were used for serodiagnosis of parasitologically confirmed Indian visceral leishmaniasis (VL) cases. All the sera of VL cases were positive by both the methods. DAT titres of VL cases were greater than or equal to 1:3,200, and ELISA values were greater than or equal to 0.55 1:400 dilution. In the control group, sera of widely prevalent diseases of India, such as leprosy, tuberculosis, malaria, and liver cirrhosis, were included. Both tests could discriminate between VL and other patients of the control group. The sera of post-kala-azar dermal leishmaniasis (PKDL) patients gave OD values of greater than 0:55 and had DAT titres of 1:1,600. Both tests are sensitive and specific for the diagnosis of VL cases. DAT, being simpler and more economical, will be suitable for diagnosis and epidemiological studies for VL under rural conditions of India.
