How common is acute interstitial nephritis?
Acute interstitial nephritis is an important cause of acute renal failure resulting from immune-mediated tubulointerstitial injury, initiated by medications, infection, and other causes. Acute interstitial nephritis may be implicated in up to 15 percent of patients hospitalized for acute renal failure.
What does acute interstitial nephritis?
Acute interstitial nephritis (AIN) is a renal lesion that typically causes a decline in kidney function and is characterized by an inflammatory infiltrate in the kidney interstitium . It is most often induced by drug therapy.
Who gets acute interstitial nephritis?
The following can cause interstitial nephritis: Allergic reaction to a drug (acute interstitial allergic nephritis). Autoimmune disorders, such as antitubular basement membrane disease, Kawasaki disease, Sjögren syndrome, systemic lupus erythematosus, or granulomatosis with polyangiitis. Infections.
What is the difference between acute tubular necrosis and interstitial nephritis?
For example, acute interstitial nephritis (AIN) requires withdrawal of the offending drug and immunosuppressive therapy, while acute tubular injury (ATI) does not have any disease-specific therapies. Failure to distinguish AIN from ATI in a timely manner can lead to kidney fibrosis and chronic kidney disease.
How common is tubulointerstitial nephritis?
Tubulointerstitial Nephritis and Uveitis Syndrome (TINU) Syndrome. TINU is a rare disorder with only 133 cases reported in the literature by 2001 . TINU accounts for less than 2 % of cases of uveitis [1, 51, 52]. The median age at presentation is 15 years and the female to male ratio is 3:1 [52, 53].
Which of the following drugs is a common cause of interstitial nephritis?
The medications that are known to cause this sort of reaction are β-lactam antibiotics such as penicillin and cephalexin, and nonsteroidal anti-inflammatory drugs (aspirin less frequently than others), as well as proton-pump inhibitors, rifampicin, sulfa medications, fluoroquinolones, diuretics, allopurinol, mesalamine …
What is the ICD 10 code for acute interstitial nephritis?
Tubulo-interstitial nephritis, not specified as acute or chronic. N12 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM N12 became effective on October 1, 2021.
What is acute nephritis?

Which of the following drug is a common cause of interstitial nephritis?
Acute interstitial nephritis is an immune process that is most commonly caused by penicillins, diuretics, allopurinol, nonsteroidal anti-inflammatory drugs, cimetidine, and sulfonamides. Prompt recognition of the disease and cessation of the responsible drug are usually the only necessary therapy.
Can nephritis be reversed?
Although nephritis may not always be curable, proper treatment can keep the condition at bay and protect the kidneys. It is essential to follow the doctor’s instructions carefully to prevent and limit kidney damage. If kidney failure occurs, a person may require dialysis or a kidney transplant.
How can you tell the difference between AIN and ATN?
In general, a scan that is considered positive and indicative of AIN requires at least 2+ intensity in the kidneys. One situation where renal scanning with 67gallium scintigraphy may be useful is in differentiating AIN from ATN when kidney biopsy is contraindicated or refused by the patient.
How common is TINU?
TINU is a rare condition, and estimates of its prevalence within patients attending specialist uveitis services range from <0.1% to 2% in ‘all age’ populations and up to 2.3% in paediatric populations (Table 1).
