In simple words: Diphtheritic tubulo-interstitial nephropathy is a kidney complication from diphtheria. It's caused by bacteria spread through coughs and sneezes.

Diphtheritic tubulo-interstitial nephropathy, a complication of diphtheria, affects the kidneys. It's caused by the bacterium Corynebacterium diphtheriae, usually acquired through direct contact with respiratory droplets from an infected person's coughs or sneezes.

Example 1: A patient presents with sore throat, weakness, swollen neck glands, and stiff neck. Further examination reveals kidney dysfunction, leading to a diagnosis of diphtheritic tubulo-interstitial nephropathy., A child with a confirmed diphtheria diagnosis develops abdominal pain, frequent urination, and fever, indicating diphtheritic tubulo-interstitial nephropathy as a complication., An individual with known exposure to diphtheria experiences weight loss, fever, and kidney-related symptoms, leading to a diagnosis of diphtheritic tubulo-interstitial nephropathy.

Documentation should include symptoms (e.g., sore throat, weakness, swollen glands, abdominal pain, frequent urination), exposure history, physical examination findings, and renal biopsy results (if performed). Details about diphtheria diagnosis and treatment are also crucial.
