A man who was an inactive hepatitis B virus (HBV) carrier with positive hepatitis B surface antigen (HBs antigen) and undetectable HBV-DNA under anti-viral treatment developed nephrotic syndrome at 52 years old, and a renal biopsy revealed advanced membranous nephropathy (MN) with focal cellular crescents, interstitial hemorrhaging, and peritubular capillaritis. Immunofluorescence studies demonstrated granular IgG deposition and HBs antigen-positivity along the capillaries. ⋯ We considered MN combined with small-vessel vasculitis due to HBV infection. These results suggest that HBV-related kidney disease should be considered even in patients with an inactive HBV carrier status under treatment.

Transition of Patients with Childhood-onset Rheumatic Diseases to Adult Medical Care in Japan.
Medical advances in childhood-onset chronic diseases (CCDs) have significantly improved the prognosis of these diseases; however, they have also resulted in an increase in the number of cases requiring continued medical care in adulthood. The transition from the pediatric to adult healthcare system has recently received worldwide attention. In Japan, in the last decade, there has been a growing awareness of the transition to adult health care in each specialized chronic disease area with a childhood onset. ⋯ The characteristics of pediatric rheumatic diseases, which are rarer than non-pediatric rheumatic diseases, and the status and problems in transition will be outlined. The mission of pediatricians is not only to follow up diseases but also to support patients' independence. All medical staff and multidisciplinary professionals must cooperate toward this new goal.
