To select the best mathematical formula for ambulatory monitoring of glomerular filtration rate (GFR) in patients with plasma cell dyscrasias (PCD's) we evaluated GFR in 32 pts (22 M + 10 F; mean age 66.1 +/- 9.6) with newly recognized PCD's with the following routine GFR tests: creatinine concentration in serum (Crs); 24 hr's standard creatinine clearance (Crcl) as a reference test; calculation of GFR from Baracskay (BGFR) and Cockcroft-Gault (C-GGFR) formulas. There were: 16 pts without monoclonal proteinuria MP(-) and 16 pts with monoclonal proteinuria MP(+) (0.44-40.3; mean 9.54 g/day). The abnormal values for Crs were defined as > 1.5 mg/dl; for Crcl as < 80.0 ml/min. Only 41% (13/32) of pts had abnormal values of Crs and 84% (27/32) had abnormal values of Crcl. In the group of pts without monoclonal proteinuria MP(-) statistical significance between 24-hr's creatinine clearance and GFR calculated by Cockcroft-Gault as well as Baracskay formulas was not stated. In the group of pts with monoclonal proteinuria MP(+) statistical significance was not stated only between 24-hr's creatinine clearance and GFR calculated by Cockcroft-Gault formula. That was no statistical significance in GFR evaluated with this methods between patients with kappa and lambda monoclonal proteinuria. We concluded, that for ambulatory monitoring of pts with PCD's MP(+) only Cockcroft-Gault formula is recommended. On the other hand pts MP(-) might be monitored using Barasckay as well as Cockcroft-Gault formulas. Because Csr over estimated values of Crcl in both groups of pts, the other serum marker of GFR should be investigated.

Emphysematous pyelonephritis (EPN) is a severe necrotizing infection of the renal parenchyma. The clinical course of EPN can be severe and life-threatening if not recognized and treated promptly. Most of the information has been from case reports, a few large series have also been reported. Using an evidence-based approach, this review describes the pathogenesis, classification, complications, and management of EPN. Emphysematous pyelonephritis (EPN) is an acute severe necrotizing infection of the renal parenchyma and its surrounding tissues that results in the presence of gas in the renal parenchyma, collecting system, or perinephric tissue. The cause for mortality in EPN is primarily due to septic complications. Up to 95% of the cases with EPN have underlying uncontrolled diabetes mellitus. The risk of developing EPN secondary to a urinary tract obstruction is about 25-40%. There are three classifications of EPN based on radiological findings. Acute renal failure, microscopic or macroscopic haematuria, severe proteinuria are other positive findings in EPN. Escherichia coli is the most common causative pathogen with the organism isolated on urine or pus cultures in nearly 70% of the reported cases. A plain radiograph shows an abnormal gas shadow in the renal bed raising the suspicion whereas an ultrasound scan or computed tomography (CT) will confirm the presence of intra-renal gas thus supporting the diagnosis of EPN. Gas may extend beyond the site of inflammation to the sub capsular, perinephric and pararenal spaces. In some cases, gas was found to be extending into the scrotal sac and spermatic cord. Subsequent case studies have shown patients being successfully treated with PCD when used in addition to medical management, with significant reduction in the morality rates. PCD should be performed on patients who have localized areas of gas and functioning renal tissue is present. The treatment strategies include MM alone, PCD plus MM, MM plus emergency nephrectomy, and PCD plus MM plus emergency nephrectomy. In small proportion of patients managed with MM and PCD, subsequent nephrectomy will be required and in these patients the reported mortality is 6.6% Nephrectomy in patients with EPN can be simple, radical or laparoscopic.

Primary ciliary dyskinesia is characterized by congenital impairment of mucociliary clearance. Kartagener syndrome (KS) is a clinical variant of primary ciliary dyskinesia which is involved in situs inversus associated with chronic respiratory infections. In addition, glomerular disease in KS syndrome is rare and reported cases are limited. We had a 27-year-old female patient with KS who presented with proteinuria, hematuria, normal kidney function, and a family history of systemic lupus erythematosus. Kidney biopsy showed segmental scar with adhesion to Bowman capsule, which was indicative of focal segmental glomerulosclerosis.
