What are the primary symptoms associated with acute inflammatory nephritis (AIN)?

• A. Headache, dizziness, and nausea
• B. Acute kidney injury, fever, eosinophilia, and rash
• C. Pain in the lower back, joint pain, and increased appetite
• D. Shortness of breath, chest pain, and cough

Answer: (B)

Acute inflammatory nephritis (AIN) is characterized primarily by the body's immune response to an insult, which often leads to acute kidney injury. Key symptoms include acute kidney injury itself, which manifests as an increase in serum creatinine and oliguria or anuria. Additionally, patients typically experience fever due to the inflammatory process, which indicates a systemic response to the underlying condition, often related to infections or drug reactions. Eosinophilia, the presence of a higher than normal number of eosinophils in the blood, is commonly observed in AIN and serves as an indicative marker for certain types of drug-induced AIN, particularly those associated with hypersensitivity reactions. A rash may also develop as part of the hypersensitivity reaction, further linking it to the associated inflammatory processes. In contrast, other listed symptoms such as headache, dizziness, and nausea relate more to general illness rather than specifically identifying AIN. Similarly, pain in the lower back, joint pain, and increased appetite does not capture the hallmark symptoms of AIN, while symptoms like shortness of breath, chest pain, and cough are more relevant to respiratory issues or cardiovascular conditions rather than acute nephritis. Thus, the combination of acute kidney injury, fever, eosinophilia,
