IL-17-producing T cells infiltrate kidneys of patients with lupus nephritis, and IL-23-treated lymph node cells from lupus-prone mice may transfer disease to Rag1-deficient mice. In this study, we show that IL-23R-deficient lupus-prone C57BL/6-lpr/lpr mice display decreased numbers of CD3(+)CD4(-)CD8(-) cells and IL-17A-producing cells in the lymph nodes and produce less anti-DNA Abs. In additi...

Nephritis characterized by IgA mesangial depositions has been described both in Henoch-Schoenlein purpura (HSP) and in Berger's disease (BD), but common genetic traits are still uncertain. We report here the case of two brothers, the first affected by HSP with persistent nephritis and the second by BD, accidentally discovered as silent microhematuria 1 year after HSP onset in the first brother....

Voclosporin (Lupkynis™), a novel calcineurin inhibitor, is approved in the USA as an add-on to background immunosuppressive therapy adults with active lupus nephritis. Voclosporin, combination mycophenolate mofetil and low-dose corticosteroids, achieved higher complete renal response rates nephritis than corticosteroids alone. treatment led early sustained reductions proteinuria. was generally ...

Although it is now well over 100 years since Richard Bright described that group of diseases to which his name is still attached, no final agreement has yet been reached on their proper definition and classification. It is true that chronic pyelonephritis and essential hypertension have been defined as conditions clearly distinct from true nephritis in respect of their aetiology and early cours...

Drug associated acute interstitial nephritis and minimal change disease has been well documented but the simultaneous presentation of both is rare and has not been reported with clarithromycin. We describe a case of simultaneous acute tubulointerstitial nephritis and minimal change disease induced by clarithromycin. The patient had acute kidney injury, nephrotic syndrome, eosinophilic pneumonit...

The gold standard to diagnose the lupus nephritis is the renal biopsy. It provides information not only for diagnosis but also for the treatment plan and the prognosis. Laboratory studies, including the immunological profile, play an essential role in diagnosing and evaluating the lupus nephritis activity. The patient is unlikely to have the active lupus nephritis with the combination of anti-d...

A 26-year old woman with diffuse active lupus nephritis showed no proteinuria. Electron microscopy revealed a typical fingerprint pattern in glomerular subendothelial electron dense deposits. Out of 21 renal biopsy cases of lupus nephritis, we found fingerprint deposits in 4 cases (19%) including the present case. All of the cases showed diffuse proliferative glomerulonephritis with overt prote...

Sarcoidosis is a systemic disease with multiorgan involvement which can cause renal failure through several different mechanisms. Granulomatous interstitial nephritis is an important albeit less frequent cause of clinically significant renal disease. Herein, we present the case of a 46 year old woman with a history of sarcoidosis whom we evaluated for rapidly worsening kidney function and prote...

Acute interstitial nephritis is a common cause of acute kidney injury. Acute interstitial nephritis is most commonly induced by drug although the cause may also be infective, autoimmune, or idiopathic. Although eosinophilia and eosinophiluria may help identify this disease entity, the gold standard for diagnosis remains renal biopsy. Prompt diagnosis is important because discontinuation of the ...

We encountered an unusual and rare case of 59-year-old woman with Churg-Strauss syndrome (CSS) showing myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA)-related acute renal insufficiency accompanied by eosinophilic tubulointerstitial nephritis. To date, reports in English of CSS presenting with rapidly progressive/acute renal insufficiency and biopsy-proven renal lesions have been...
