Abstract

Since Wands et al. reported for the first time in 1975 the reactivation of the hepatitis B virus in hematologic disease patients who had been receiving chemotherapy, the efficacy of chemotherapy and immunosuppressants has improved. As a result, the frequency of the reactivation of hepatitis B is increasing. Reported herein is a case of a non-Hodgkin lymphoma patient in her 70s who was suspected to have had HBsAg negative/anti-HBs negative occult HBV infection. The patient experienced fulminant hepatitis caused by the reactivation of hepatitis B, and died three months after the R-CHOP regimen was completed. In the HBsAg negative plus HBV DNA-negative case, there were few instances of viral activation of HBV. In this case, antiviral therapy was needed when the patient was confirmed to have become HBV DNA positive through regular monitoring, but its necessity is often overlooked, unlike the preemptive antiviral treatment in the HBsAg positive cases.

Abstract

Bartter syndrome is a renal tubular defect in electrolyte transport characterized by hypokalemia, metabolic alkalosis, hyperreninemia, hyperaldosteronism, normal blood pressure, and other clinical symptoms. As a clinical and genetical heterogeneous disorder, this syndrome can be classified into two clinical variants, antenatal Bartter syndrome and classic Bartter syndrome according to the onset age. Nephrocalcinosis is common in antenatal Bartter syndrome, but is rare in classic Bartter syndrome. It can also be classified into five genetic subtypes by the underlying mutant gene, all of which are expressed in the tubular epithelial cells of the thick ascending limb of the loop of Henle. Patients with Bartter syndrome type 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. We have experienced a case of Bartter syndrome with nephrocalcinosis in a 42-year-old woman diagnosed by biochemical and radiologic studies. We had successful response with potassium chloride and spironolactone.
