Polycystic kidney disease (PKD) is characterized by multiple renal cysts, which ultimately result in renal failure. We have reported the identification of a new gene, Ke 6, within the major histocompatibility complex, which is downregulated in two different mouse models of heritable PKD (N. Aziz, M. Maxwell, B. St.-Jacques, and B.M. Brenner. Mol. Cell. Biol. 13: 1847-1853, 1993). The Ke 6 gene gives rise to two transcripts, Ke 6a and Ke 6b. Ke 6a protein has significant homology to several mammalian and bacterial steroid dehydrogenases. The homology of Ke 6a protein to specific functional domains of the human and rat 11 beta-hydroxysteroid dehydrogenase enzyme (11 beta-HSD), which inactivates glucocorticoids, is substantial. We report here that the Ke 6 gene and the 11 beta-HSD gene are regulated in the same aberrant pattern in the cpk mouse. The strong evidence for a critical role of steroids in cystogenesis leads us to propose that a possible elevation of intrahepatic and intrarenal steroid levels occurs in the cpk mouse as a result of repression of steroid metabolic enzymes, which ultimately leads to development of cysts.

Many common chronic inflammatory rhinosinusitis conditions (hypertrophic sinus disease [HSD]) have the histopathological profile of allergic or asthmatic inflammation. Allergic fungal sinusitis (AFS) is both a type of noninvasive fungal rhinosinusitis and a type of HSD. AFS has clinicopathological features that make it similar, but not identical, to allergic bronchopulmonary aspergillosis (ABPA). Allergic mucin is a defined pathological entity occurring in ABPA, AFS, and in the HSD "eosinophilic mucin rhinosinusitis (EMRS)." Diagnosis of AFS requires a careful review of surgical reports, histopathology, and culture results. Treatment includes surgery and aggressive postoperative medical management of allergic inflammatory disease. Prognosis is good with integrated medical-surgical follow-up, but recurrence remains problematic. The association of ABPA, AFS, and HSD with class II genes of the major histocompatibility complex places the initiation of these inflammatory diseases within the context of antigen presentation and the acquired immune response. Pathological immunomanipulation of this response by local microbial superantigens may be a common mechanism for disease pathogenesis. Future research into the molecular biology of these related conditions may offer insight into the pathogenesis of other chronic inflammatory diseases.
