Interstrand cross-link (ICL) hypersensitivity is a characteristic trait of Fanconi anemia (FA). Although FANCD2-associated nuclease 1 (FAN1) contributes to ICL repair, FAN1 mutations predispose to karyomegalic interstitial nephritis (KIN) and cancer rather than to FA. Thus, the biological role of FAN1 remains unclear. Because fork stalling in FAN1-deficient cells causes chromosomal instability, we reasoned that the key function of FAN1 might lie in the processing of halted replication forks. Here, we show that FAN1 contains a previously-uncharacterized PCNA interacting peptide (PIP) motif that, together with its ubiquitin-binding zinc finger (UBZ) domain, helps recruit FAN1 to ubiquitylated PCNA accumulated at stalled forks...

Pulmonary manifestations of systemic lupus erythematosus (SLE) include, but are not limited to, pneumonia, interstitial pneumonitis, atelectasis and pleural effusion. Cavitary lung lesions are rarely associated with SLE. We present herein the case of a female patient with SLE and lupus nephritis who presented to the hospital with respiratory failure, rash and arthralgias. She was found to have a cavitary lung lesion most concerning for infection. However, despite an extensive inpatient antibiotic course, her symptoms persisted...

Acute interstitial nephritis (AIN) is known as a common cause of acute kidney injury, found in 15% to 27% of kidney biopsies. Drug-induced AIN is currently the most common cause of AIN. The most common medications causing AIN are antibiotics and nonsteroidal anti-inflammatory drugs. We describe a case of Citrullus colocynthis (herbal remedy for diabetes mellitus and weight reduction) that induced AIN. A 31-year-old woman with major thalassemia, diabetes mellitus, and hepatitis C infection was admitted because of flank pain and unexpected increase in serum creatinine level...

With the recent introduction of more potent modern immunosuppressive regimens in solid-organ transplant, new types of viral infections such as adenovirus are emerging as a potential cause for graft dysfunction and loss. We report a case of 41-year-old male patient with end-stage renal disease from recurrent kidney stones who underwent kidney transplant from a deceased 12-year-old female donor. He developed adenoviral infection with acute cystitis, microscopic hematuria, and necrotizing interstitial nephritis associated with graft dysfunction within the first month of the postoperative period...

Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen...

Leptospirosis is the most prevalent zoonosis affecting more than 1 million populations worldwide. Interestingly, leptospirosis endemic regions coincide with chronic kidney disease (CKD) hotspots largely due to flooding and agricultural overlaps. Acute leptospirosis induces multiple organ dysfunction including acute kidney injury and may predispose to CKD and end-stage renal disease, if not treated timely. Asymptomatic infection may carry the bacteria in the kidney and CKD progresses insidiously. Histologic finding of leptospirosis renal disease includes tubulointerstitial nephritis, interstitial fibrosis, and tubular atrophy...

Acute kidney injury (AKI) is a very common complication after allogeneic bone marrow transplantation (BMT) and is associated with a poor prognosis. Generally, the kidneys are assumed to not be no direct targets of graft-versus-host disease (GvHD), and renal impairment is often attributed to several other factors occurring in the early phase after BMT. Our study aimed to prove the existence of renal GvHD in a fully major histocompatibility complex (MHC)-mismatched model of BALB/c mice conditioned and transplanted according to 2 different intensity protocols...

Human immunodeficiency virus (HIV) infection continues to be a leading cause of morbidity and mortality. HIV-infected individuals are now surviving for a relatively longer period and this is because of easy accessibility to antiretroviral therapy these days. As a result, chronic disease-related complications are now being recognized more often. Kidney disease in HIV-infected children can vary from glomerular to tubular-interstitial involvement. We searched the database to identify various kidney diseases seen in HIV-infected children...

Renal complications from snakebite result in high mortality and morbidity. Acute kidney injury (AKI) occurs in 5-30% of cases. Renal manifestation could include acute tubular necrosis, cortical necrosis, interstitial nephritis, glomerulonephritis, and vasculitis. We present a case of thrombotic microangiopathy (TMA) resulting in renal cortical necrosis. Renal biopsy showed fibrin thrombi in glomeruli and arterioles with cortical necrosis. Our patient progressed to end-stage renal disease.
