Summary
This summary is machine-generated.A case study reports acute tubulointerstitial nephritis (TIN) in a 12-year-old after the second Pfizer COVID-19 vaccine dose. Treatment with corticosteroids and mycophenolate mofetil (MMF) improved kidney function.
Area Of Science
- Nephrology
- Immunology
- Vaccinology
Background
- COVID-19 vaccination is expanding to younger age groups and boosters.
- Monitoring vaccine safety, including rare adverse events, remains crucial.
Purpose Of The Study
- To report a case of acute tubulointerstitial nephritis (TIN) following COVID-19 vaccination.
- To discuss the temporal association between the Pfizer vaccine and TIN.
- To highlight treatment strategies for vaccine-associated TIN.
Main Methods
- Case report of a 12-year-old female presenting with acute kidney injury post-vaccination.
- Renal biopsy confirmed acute tubulointerstitial nephritis (TIN).
- Treatment involved corticosteroids and mycophenolate mofetil (MMF).
Main Results
- Acute kidney injury developed 6 days after the second Pfizer COVID-19 vaccine dose.
- Renal biopsy showed idiopathic severe acute tubulointerstitial nephritis (TIN).
- Kidney function improved with pulse methylprednisolone and oral prednisone, but relapsed upon discontinuation; MMF led to sustained recovery.
Conclusions
- A temporal association exists between the second dose of the Pfizer COVID-19 vaccine and acute TIN.
- Treatment with corticosteroids followed by MMF was effective in managing vaccine-associated TIN.
- Further investigation is needed regarding potential associations between specific vaccine protocols and TIN incidence.

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
