Iron deposited may exacerbate renal damage through processes like lipid peroxidation and free radical formation, impacting cellular function and precipitating renal disease. Although seen commonly with chronic intravascular hemolysis in the setting of sickle cell anemia, thalassemia, and in the setting of prosthetic cardiac valves. While acute renal failure following prosthetic cardiac valve placement is relatively uncommon, some cases of renal injury in the setting of mechanical hemolysis have been reported, in the postsurgical period, typically within 2 weeks. In this case report, we present a 67-year-old male patient, following mitral valve repair, who developed anemia within 2 weeks of the repair. Evaluation with echocardiography did not initially show findings of worsening mitral regurgitation, however, his anemia and kidney function worsened over the next 6 months. Further evaluation, during that time showed worsening mitral valve regurgitation in repeated echocardiography, with renal hemosiderosis confirmed via kidney biopsy, revealing glomerulosclerosis with hemosiderin deposits. Due to persisting anemia and worsening kidney function, the patient is being planned for a mitral valve replacement. The potential recovery of renal function remains uncertain. Despite the common occurrence of intravascular hemolysis following prosthetic valve placement or valve repair, only a few cases of acute renal failure have been reported. In these cases, severe hemolytic anemia developed shortly after surgery, within 2 weeks, with increased levels of creatinine, even reported as high as 8.2 mg/dL and renal biopsy revealed acute tubular injury and widespread tubular hemosiderosis, resembling the findings in the index case. Diagnosis depends on the evaluation of anemia, showing signs of hemolysis, with echocardiology findings of worsening valvular abnormalities, and kidney biopsy findings showing hemosiderin deposits. Treatment strategies encompass the management of anemia alongside considerations for either mitral valve replacement or repair. This case underscores the importance of considering the possibility of renal hemosiderosis, associated with mitral valve repair. The delay in diagnosis observed in this case is not uncommon, and timely recognition becomes pertinent to prevent irreversible renal injury and improve long-term outcomes.</p>","PeriodicalId":9604,"journal":{"name":"Case Reports in Nephrology","volume":"2025 ","pages":"2777348"},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11944868/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143718042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extrapulmonary TB (EPTB) accounts for only 10%-17% of TB cases. The diagnosis of EPTB is challenging, especially in low-resource settings, because TB can present with clinical characteristics of rheumatological, oncological, or other infectious diseases. Occasionally, mycobacterial infection stimulates the immune system, inducing the generation of antibodies that may lead to autoimmune diseases secondary to primary TB infection, such as vasculitis. To the best of our knowledge, no data have been reported on the prevalence of vasculitis, although some studies worldwide have determined that small-vessel vasculitis is the most common. Here, we present a case report of a male patient with EPTB diagnosed with <i>Microscopic polyangiitis</i> (MPA). <b>Methods:</b> A 17-year-old boy with no past medical history visited the emergency room with a three-day history of gastrointestinal bleeding. During hospitalization, acute kidney injury (AKI), disseminated lymphadenopathy, imaging studies, renal biopsy, and immunological tests were performed to confirm the diagnosis. <b>Results:</b> Endoscopy revealed a duodenal lesion containing <i>Mycobacterium TB</i> DNA. Further investigation of AKI led to autoimmune serological tests and kidney biopsy, confirming the diagnosis of antineutrophil cytoplasmic antibodies (ANCA)-positive pauci-immune GN. The patient was treated with antituberculous agents, steroids, and plasmapheresis. However, he developed alveolar hemorrhage and respiratory failure leading to death. <b>Conclusion:</b> TB is a common disease in low-income countries, with the pulmonary form being the most common presentation; however, the bacteria can spread to any organ, known as EPTB. It is important to consider that the inflammatory reaction associated with any form of TB can generate other types of noninfectious inflammatory diseases, such as ANCA-positive pauci-immune GN.</p>","PeriodicalId":9604,"journal":{"name":"Case Reports in Nephrology","volume":"2025 ","pages":"6619761"},"PeriodicalIF":0.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11832249/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because they have numerous etiologies and patients may present with nonspecific symptoms, renal infarcts may be mistaken for other common conditions.

Computed tomography (CT) revealed multiple right kidney infarcts, transthoracic echocardiography revealed mitral valve stenosis with no evidence of atrial fibrillation, and hypercoagulability tests were negative.

Anticoagulation therapy again led to recovery, and the patient was discharged back on warfarin. After the recurrent infarct, monitoring and cardiac care have led to adequate long-term management, and no evidence of atrial fibrillation has ever been observed. This case illustrates the challenging diagnosis of an unusual presentation of recurrent renal infarct, where each infarct was suspected to have a unique and independent etiology: mitral valve stenosis in the first and hypercoagulability from withdrawal of warfarin in the second.

The first patient presented with monoclonal membranoproliferative glomerulonephritis in the context of known chronic lymphocytic leukemia (CLL), diagnosed about 10 years prior.
