Malaria causing nephrotic syndrome –
**Core Concept**
Malaria is a vector-borne disease caused by Plasmodium parasites transmitted through the bite of infected Anopheles mosquitoes. Different species of Plasmodium can cause distinct clinical manifestations, ranging from asymptomatic infections to severe complications such as nephrotic syndrome.
**Why the Correct Answer is Right**
Plasmodium malariae, also known as quartan malaria, is a long-term infection that can cause chronic kidney damage and nephrotic syndrome. This is due to the parasite's ability to infect the glomerular cells and cause immune complex deposition, leading to glomerulonephritis. The kidney damage is often irreversible, resulting in nephrotic syndrome characterized by heavy proteinuria, hypoalbuminemia, and hyperlipidemia. The chronic infection and immune response activation are thought to contribute to the renal damage.
**Why Each Wrong Option is Incorrect**
**Option A:** Plasmodium vivax is known to cause relapsing malaria due to the presence of hypnozoites in the liver, but it is not typically associated with nephrotic syndrome.
**Option B:** Plasmodium falciparum is the most virulent species, causing the most severe form of malaria, cerebral malaria, but it is not commonly linked to nephrotic syndrome.
**Option D:** Plasmodium ovale is similar to P. vivax in its clinical presentation, with a high risk of relapse, but it is not typically associated with renal damage or nephrotic syndrome.
**Clinical Pearl / High-Yield Fact**
It is essential to recognize that Plasmodium malariae can cause chronic kidney damage, leading to nephrotic syndrome, which can be a long-term complication of malaria infection. This highlights the importance of accurate diagnosis and treatment of malaria to prevent such complications.
**β Correct Answer: C. P. malariae**
