1/13. Acute interstitial nephritis.Acute allergic interstitial nephritis is manifested clinically by rash, fever, eosinophilia, hematuria, oliguria and azotemia. Histologically a monocytic inflammatory process in the renal interstitium is seen. The clinical course of a patient after excessive sodium cephalothin administration suggested allergic interstitial nephritis and implicates this drug as an etiologic agent.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
2/13. Acute tubulo-interstitial nephritis leading to acute renal failure following multiple hornet stings.BACKGROUND: Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. CASE PRESENTATION: We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis). He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. CONCLUSION: Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
3/13. Suspected ciprofloxacin-induced interstitial nephritis.Interstitial nephritis is a rare but serious adverse effect of many drugs and usually is diagnosed by clinical signs and symptoms of hematuria, proteinuria, eosinophilia, fever, azotemia, and rash. ciprofloxacin is one drug that has been reported to cause interstitial nephritis. Renal toxicities have been reported in less than one percent of the patients receiving ciprofloxacin therapy. Limited documentation of this adverse effect exists in the literature. This article describes a patient with suspected ciprofloxacin-induced interstitial nephritis.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
4/13. sodium wasting, acidosis and hyperkalemia induced by methicillin interstitial nephritis. Evidence for selective distal tubular dysfunction.A 61 year old male patient was studied who manifested dehydration, azotemia, acidosis and hyperkalemia six weeks after exposure to methicillin. Thyroid and adrenal glucocorticoid and mineralocorticoid function were normal. The dehydration was found to be caused by a profound sodium-losing nephropathy; urinary sodium ranged from 78 to 101 meq/day during a salt restricted diet. A distal renal tubular acidosis and a quantitively impaired ability to excrete potassium were also found. These defects were relatively unresponsive to mineralocorticoid or prednisone therapy. A renal biopsy specimen showed an interstitial nephritis which selectively affected distal tubules and was thought to be secondary to methicillin. The data suggest functional impairment specific for the distal tubule, but with only a modest decrease in the glomerular filtration rate.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
5/13. captopril-associated acute interstitial nephritis.A 57-year-old male with mild impairment of renal function secondary to diabetic glomerulosclerosis developed acute renal failure (creatinine 32.4 mg/dl) associated with a generalized desquamative skin rash and peripheral eosinophilia shortly after initiation of antihypertensive therapy with captopril. An acute interstitial nephritis was demonstrated on renal biopsy, and improvement was temporally related to initiation of therapy with prednisone. A review of the literature revealed 5 similar cases in whom acute deterioration of renal function occurred following initiation of captopril and in whom there were features of a hypersensitivity reaction, including skin rash, fever, eosinophilia, azotemia, eosinophiluria, and a Coombs-positive hemolytic anemia. Renal biopsy, where available, revealed an acute interstitial nephritis. Observations from these cases suggest that, of the angiotensin-converting enzyme inhibitors, this syndrome appears to be specific for captopril, begins within the 1st month of therapy, is not dose-dependent, and generally resolves on cessation of therapy. steroids may hasten recovery, but sufficient data are not available to confirm their efficacy.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
6/13. Acute interstitial nephritis associated with vancomycin therapy.Nephrotoxicity due to vancomycin is relatively uncommon and usually occurs in patients receiving concomitant therapy with an aminoglycoside or in patients with preexisting renal disease receiving prolonged courses of therapy and who exhibited excessive serum levels. We treated a healthy young woman who developed acute interstitial nephritis and moderate reversible azotemia associated with intravenous vancomycin hydrochloride therapy.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
7/13. Acute granulomatous interstitial nephritis due to co-trimoxazole.A 51-year-old man with diabetes mellitus and mild hypertension developed acute interstitial nephritis 4 days after starting a course of co-trimoxazole for bronchopneumonia. Following initial symptoms of overt hypersensitivity, he developed azotemia and renal tubular dysfunction with malaise and anorexia requiring hospitalization. Renal pathology demonstrated an acute granulomatous interstitial nephritis superimposed on chronic diabetic renal disease.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
8/13. Type 4 renal tubular acidosis (sub-type 2) associated with idiopathic interstitial nephritis.An 18-month-old girl presenting with anorexia and failure to thrive, was referred for adenoidectomy. Arterial hypertension was discovered on physical examination. Laboratory results revealed hyperkalaemic, hyperchloraemic, metabolic acidosis, with slight azotemia. Urinary aldosterone excretion and plasma renin were decreased. Renal biopsy showed idiopathic interstitial nephritis. The diagnosis of type 4 renal tubular acidosis, sub-type 2, i.e. primary hyporeninaemic secondary hypoaldosteronism was proposed. According to our knowledge, this disease has not previously been reported in young children, but is well known in azotaemic adults. We therefore propose the inclusion of this uncommon renal disease in the differential diagnosis of failure to thrive in childhood.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
9/13. Interstitial nephritis in a patient with legionnaires' disease.Renal involvement in legionnaires' disease is a well-known, yet incompletely understood, complication. Manifestations of renal involvement include proteinuria, hematuria, pyuria, cylindruria, and azotemia. Previous cases of legionnaires' disease with renal involvement have shown pathophysiologic changes consistent with acute tubulointerstitial nephritis or acute tubular necrosis. A toxic metabolite produced by legionella pneumophila has been theorized to produce a vasoconstrictive effect on the renal microvasculature, leading to ischemia and renal dysfunction. The case reported here is unique in that the patient presented with interstitial nephritis in the absence of pulmonary signs or symptoms.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
10/13. Acute renal failure in rocky mountain spotted fever.review of clinical and pathologic data from ten fatal cases of rocky mountain spotted fever (RMSF) revealed the importance of acute renal failure in the clinical course and of multifocal perivascular interstitial nephritis as the principal pathologic lesion. In nine cases, rickettsia rickettsii were demonstrated by immunofluorescence in the areas of vasculitis. Evidence was lacking for the role of disseminated intravascular coagulation, glomerulonephritis, or myoglobinuria in the pathogenesis of acute renal failure in these cases. Rickettsia-induced vascular injury led to acute renal failure by several mechanisms. hypovolemia early in the course resulted in reversible, prerenal azotemia. Transient hypotension in midcourse produced acute tubular necrosis. In fulminant cases, preterminal circulatory collapse was associated with coma and oliguria. The interstitial nephritis could not be demonstrated conclusively to contribute to the acute renal failure.- - - - - - - - - - ranking = 1keywords = azotemia (Clic here for more details about this article) |
