IgG4-related disease (IgG4-RD) is a newly recognized multi-organ fibro-inflammatory condition with characteristic histopathological findings of increased IgG4+ plasma cells in tissue and usually with increased IgG4 serum levels. Kidney involvement in IgG4-RD has been well described since 2006. Epstein-Barr virus (EBV) has reportedly been associated with nodal IgG4-RD, but not in extra-nodal disease. We report a case of renal IgG4-RD in the setting of acute EBV infection in a young healthy man, resulting in severe renal failure. Biopsy of kidney revealed IgG4+ plasma cell-rich tubulointerstitial nephritis, tissue eosinophilia, early-stage membranous nephropathy, and scattered EBV-positive cells. Oral prednisone and acyclovir only partially rescued his renal function.

BACKGROUND: Diagnosis of adrenal-cortisol insufficiency is often misleading in hospitalized patients, as clinical and biochemical features overlap with comorbidities. We analyzed clinical determinants associated with a biochemical diagnosis of adrenal-cortisol insufficiency in non-intensive care unit (ICU) hospitalized patients. METHODS: In a retrospective cohort study we reviewed 4668 inpatients with random morning cortisol levels ≤15 µg/dL hospitalized in our center between 2003 and 2010. Using serum cortisol threshold level of 18 µg/dL 30 or 60 minutes after Cortrosyn (250 µg; Amphastar Pharmaceuticals, Inc., Rancho Cucamonga, Calif) injection to define biochemical adrenal-cortisol status, we characterized and compared insufficient (n = 108, serum cortisol ≤18 µg/dL) and sufficient (n = 394; serum cortisol >18 µg/dL) non-ICU hospitalized patients. RESULTS: Commonly reported clinical and routine biochemical adrenal-cortisol insufficiency features were similar between insufficient and sufficient inpatients. Biochemical adrenal-cortisol insufficiency was associated with increased frequency of liver disease, specifically hepatitis C (P = .01) and prior orthotopic liver transplantation (P <.001), human immunodeficiency virus (HIV; P = .005), and reported pre-existing male hypogonadism (P <.001), as compared with the biochemical adrenal-cortisol sufficiency group. Forty percent of insufficient inpatients were not treated with glucocorticoids after diagnosis. Multivariable logistic analysis demonstrated that inpatients with higher cortisol levels (P = .0001) and higher diastolic blood pressure (P = .05), and females (P = .009) were more likely not to be treated, while those with previous short-term glucocorticoid treatment (P = .002), other coexisting endocrine diseases (P = .005), or who received an in-hospital endocrinology consultation (P <.0001), were more likely to be replaced with glucocorticoids. CONCLUSIONS: Commonly reported adrenal-cortisol insufficiency features do not reliably identify hospitalized patients biochemically confirmed to have this disorder. Comorbidities including hepatitis C, prior orthotopic liver transplantation, HIV, and reported pre-existing male hypogonadism may help identify hospitalized non-ICU patients for more rigorous adrenal insufficiency assessment.
