This report describes a clinical case of Leptospira interrogans serovar Pomona infection in finishing pigs, associated with multifocal interstitial nephritis that resulted in carcass condemnation at slaughter. Clinical signs of leptospirosis were not observed. On gross examination, kidneys varied from slightly shrunken to 1.5 times normal size, with pale mottling extending through the cortex an...

Porcine circovirus type 2 (PCV2) is now recognised as the causal agent of porcine multisystemic wasting syndrome (PMWS), an economically important wasting disease of young pigs [J. Vet. Diagn. Invest. 12 (2000) 3]. Gross lesions of PMWS include generalised lymphadenopathy, hepatitis, nephritis and pneumonia and typical histological lesions include lymphocytic depletion and multinucleated giant ...

Interstitial nephritis is a common cause of renal dysfunction. It is primarily caused by drugs, infections, or autoimmune disorders. Patients with human immunodeficiency virus (HIV) infection can develop interstitial nephritis, although it typically occurs because of the aforementioned etiologies and not as a direct consequence of HIV infection. Interstitial lesions may occur in patients with H...

Granulomatous interstitial nephritis is an uncommon but potentially reversible cause of impaired kidney function. In the native kidney, granulomatous interstitial nephritis is commonly attributed to drug hypersensitivity, sarcoidosis, or tubulointerstitial nephritis and uveitis, with a significant fraction of cases labelled as ‘idiopathic’ [1]. In kidney transplant recipients, the incidence of ...

this study was carried out to determine the prevalence and type of renal lesions in cattle that were slaughtered at the ghaem (shahriar) and ziaran (ghazvin) abattoirs. a total number of 405 clinically normal cattle were randomly selected and renal samples were taken for histopathological study. the cattle were divided into two groups according to sex, and female groups were divided into two ag...

Granulomatous interstitial nephritis has been observed in <1% of native renal biopsies. Here, we describe two patients with granulomatous interstitial nephritis in relation to Crohn's disease. Circulating helper and cytotoxic T cells were highly activated, and both cell types predominated in the interstitial infiltrate, indicating a cellular autoimmune response. After immunosuppressive treatmen...

Predominant interstitial nephritis is a rare manifestation of systemic lupus erythematosus. Only seven cases have been reported in the literature. Owing to the rarity of this entity, the natural history of predominant interstitial nephritis in lupus has not been adequately recorded and an appropriate therapeutic approach has yet to be defined. In this report we present the case of a 25 year old...

Acute interstitial nephritis is a relevant cause of acute renal failure. Drugs are the predominant cause, followed by infections and idiopathic lesions. Acute interstitial nephritis as a form of hypersensitivity reaction is an uncommon manifestation in the setting of human parasitic infections. We present a case of acute interstitial nephritis in association with Giardia infection in a 54-year-...

Paraquat is a commonly used herbicide in many countries which can lead to systematic poisoning on exposure, In this study, paraquat (PQ)-induced changes in the expression of Cyclooxygenase-2 (COX-2) along with biochemical and histopathological changes in the lungs, liver and kidneys were studied. Twenty four male Wistar rats (180-200 g) were exposed either against saline as control group or var...
