Summary
IgA nephropathy rarely causes scleritis (eye inflammation). This case highlights a patient with IgA nephropathy presenting with scleritis, successfully treated with oral steroids, showing no recurrence.
Area of Science:
- Nephrology
- Ophthalmology
- Immunology
Background:
- IgA nephropathy (IgAN) is a primary glomerulonephritis characterized by IgA deposition in the renal glomeruli.
- Ocular manifestations in IgAN are rare, with scleritis being an exceptionally uncommon presentation.
- This report focuses on a unique case linking scleritis to diagnosed IgA nephropathy.
Purpose of the Study:
- To report a rare case of diffuse anterior scleritis as the initial presentation of IgA nephropathy.
- To describe the diagnostic process and management of this unusual clinical association.
- To highlight the importance of considering systemic diseases in patients with unexplained scleritis.
Main Methods:
- Clinical case presentation of a patient with diffuse anterior scleritis.
- Laboratory investigations including urinalysis, renal function tests, and serological markers for autoimmune and infectious diseases.
- Renal biopsy for histopathological diagnosis of IgA nephropathy.
Main Results:
- The patient presented with microscopic hematuria and nephrotic-range proteinuria, with normal renal function.
- Extensive serological testing for autoimmune diseases, vasculitis, cryoglobulinemia, and infections was negative.
- Renal biopsy confirmed IgA nephropathy; treatment with oral steroids led to symptom resolution and no scleritis recurrence.
Conclusions:
- Scleritis can be an extremely rare presenting manifestation of IgA nephropathy.
- Prompt diagnosis and treatment with oral steroids can effectively manage scleritis associated with IgAN.
- This case underscores the need for a comprehensive diagnostic workup in patients with scleritis, including renal evaluation.

01:24Nephrotic Syndrome I : Introduction
1.0K
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Nursing management for nephrotic syndrome adapts as the disease progresses, with strategies evolving to address advancing symptoms and complications.Early-Stage Management In the early stages, nursing interventions for nephrotic syndrome resemble those used in managing acute glomerulonephritis, focusing on symptom monitoring, fluid balance, and managing mild to moderate edema.Vital Signs: Regularly monitor blood pressure, pulse, respiratory rate, and temperature to promptly identify...

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
