Total 160 head of porcine kidneys were examined for gross and histopathological lesions and polymerase chain reaction (PCR) for porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), Leptospira species and porcine reproductive and respiratory syndrome virus (PRRSV). Grossly, 137 kidneys (85.6%) had lesions characterized by the presence of the scattered white foci. Microscopically, multifocal interstitial nephritis, which classified into 4 grades such as, no lesion (Score 0), mild lesion (Score 1), moderate lesion (Score 2) and severe chronic lesion (Score 3) with fibrosis, was observed in 159 cases (99.4%). The histopathologic mean score for multifocal interstitial nephritis was significantly different (P<0.05) between the cases of PCV-2 single infection and the cases of co-infection with PCV-2 and PPV. According to PCR evaluation, PCV-2 were detected in 73.8% (118 cases), PPV were in 66.9% (107 cases), however Leptospira spp. and PRRSV were negative in all kidneys. Both PCV-2 and PPV were detected in 52.5% (84 cases). In 84 cases co-infected with PCV-2 and PPV, the occurrence of lymphoid follicle and vasculitis were observed as 65.5% (55 cases) and 26.2% (22 cases), respectively. These results revealed that PCV-2 and PPV were major infectious agents for interstitial nephritis in slaughtered pigs, Jeju. And the histopathologic lesions of multifocal interstitial nephritis were more severe in the case co-infected with PCV-2 and PPV.

Acute interstital nephritis can occur by acetaminophen, but it is rarely presented as acute renal failure with azotemia. We report a case of acute interstitial nephritis induced by acetaminophen in a 14-year-old girl who developed non-oliguric acute renal failure. She has taken acetaminophen to control the persistent throat pain for the last two months. Renal biopsy revealed diffuse infiltration of mononuclear inflammatory cells admixed with eosinophils in the edematous interstitia. After the discontinuation of acetaminophen and the administration of corticosteroid, the serum creatinine level returned to normal.

In order to investigate the prevalence and pattern of renal lesions in sows, 250 kidneys collected from abattoir were examined grossly and histopathologically. The prevalence of renal lesions in sows was 46.8% (l17/250). Main gross findings were consisted of congestion and/or petechiation (21.6%), cortical enlargement (15.2%), renal cysts (6.0%), abscessation (4.4%), and infarction (1.5%). Principle microscopic lesions were composed of interstitial nephritis (25.6% ), glomerulosclerosis (13.6%), glomerular thrombosis (3.6%), amyloidosis (2.0%) and glomerulosclerosis (2.0%) Sixty four kidneys with interstitial nephritis was classified by 46 chronic and 18 acute cases. Among 34 kidneys with glomerulonephritis, there were divided into 18 membranous type, 9 proliferative type and 7 membranoproliferative type. For these results, it was confirmed that sows raised in Kwangju and Chonnam areas had been affected by a variety of pathological renal lesions.

In order to investigate the renal pathology of spontaneously occurring renal lesions, basic macroscopic inspection was conducted to 3,850 pigs randomly collected from local slaughter houses, and a total of 355 pigs (9.2%) were detected with various gross pathological conditions. Renal morphologic patterns for gross lesions were classified histopathologically as 123(34.5%) congestion, 81(22.8%) acute interstitial nephritis, 52(14.7%) chronic interstitial nephritis, 49(13.8%) hemorrhage, 39(11.0%) renal cyst, 29(8.2%) chronic glomerulonephritis, 18(5.1%) acute glomeruonephritis, 14(3.9%) infarction, 11(3.1%) thrombosis, 5(1.4%) atrophy, 5(1.4%) pyelonephritis and 1(0.3%) lymphosarcoma.

In this study, 198 cases of Korean Native Cattle having renal lesions were observed during the examination of a cases and total of 350 cases in 1967. The lesions observed were 190 cases of interstitial nephritis (54.3%) I case of atrophic kindey (0.3%), 5 cases of renal cyst (1.4%) and 2 casces of renal abscess (0.6%). The interstitial nephritis was classified into focal (73.2%), local (13.6%) and diffuse (13.5%) in type. The gross and microscopic findings for the lesions were also described and discussed.

To examine the prevalence and types of kidney lesions in Korean cattle, a survey was carried out at a abattoir in september 2000 and January 2001. The collected kidneys were examined grossly and histopathologically and investigated for the patterns of renal diseases with considering season and sex. Of 735 cattle (99 bulls and 246 cows in September and 140 bulls, 3 steers, and 247 cows in January) surveyed, 301 (41%) cattle had various renal lesions. The most common prominent finding was focal or multiple interstitial nephritis (36.2%). Other lesions included focal or multiple renal cyst (9.1%), infarction (0.1%), hemorrhage (0.3%), and renal atrophy (0.3%). Microscopically, main pathological lesions were acute or chronic interstitial nephritis with moderate infiltration of neutrophil or lymphocyte, respectively. Finally, the kidney lesions are more or less correlated with the meat quality, especially in female Korean cattle.

Nineteen cases of Albino rat having naturally occurred renal lesions were observed during the routine examination of a total of 240 cases. The lesions observed were focal suppurative nephritis (6 cases), acute nonsuppurative nephritis (3 cases), chronic interstitial nephritis (4 cases), nematode infection in pelvic epithelium (5 cases, in which one case was coincident with focal suppurative nephritis) and unilateral hydronephrosis (2 cases). Gross and microscopic findings for the lesions were described and discussed.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and severe drug-induced hypersensitivity syndrome characterized by hematological abnormalities and multiorgan involvement. Liver involvement is the most common visceral manifestation. However, renal failure has been rarely described. The common culprit drugs are anticonvulsants and allopurinol. We experienced a patient with DRESS syndrome with acute interstitial nephritis caused by concomitant administration of quinolone and non-steroidal anti-inflammatory drugs (NSAIDs). A 41-year-old man presented with a diffuse erythematous rash and fever which developed after administration of quinolone and NSAIDs for a month due to prostatitis. He was diagnosed with DRESS syndrome. Skin rash, fever, eosinophilia, and elevations of liver enzymes improved with conservative treatment and discontinuation of the causative drugs. However, deterioration of his renal function occurred on day 8 of admission. The levels of blood urea nitrogen and serum creatinine increased and oliguria, proteinuria and urinary eosinophils were observed. Ultrasonography showed diffuse renal enlargement. The clinical features were compatible with acute interstitial nephritis. Despite intravenous rehydration and diuretics, renal function did not improve. After hemodialysis, his renal function recovered completely within 2 weeks without administration of systemic corticosteroid.

Gross lesions of multifocal interstitial nephritis, often called 'white spotted kidney', can be caused by various bacterial or viral hematogenous infections [1, 2]. The purpose of this study was to determine whether there is an association between these lesions in slaughter pigs and the causative agents in Jeju. (omitted)

This experiment was executed to control effectively endemic disease of swine farms in Incheon metropolitan city. Mainly using PigMon program which had been developed by the College of Veterinary Medicine in the University of Minnesota(USA), we examined lesions of gastric ulcer and interstitial nephritis additionally. 446 heads of pigs shipped from 5 farms in Incheon to a slaughterhouse from June in 2003 to May in 2004 were examined. Infection rates by farms were obtained as follows; 1. Pneumonia was varied from 34.6% to 74.1% and pneumonic score was 1.47∼7.06. As for atrophic rhinitis, four farms were 100% and one farm was 89.5% and rhinitis score was 1.3∼3.2. 2. The infection rate of pericarditis and peritonitis was 1.0∼3.9% and liver white spots, papular dermatitis were observed in pigs of 9.8∼29.7%, 16.7∼51.4% respectively. 3. The outbreak rates of interstitial nephritis, lesions of ileal thickening and gastric ulcer were 15.4∼24.1%, 7.7∼13.5%, and 62.7%∼86.2% respectively.
