A 35-year-old woman who had been suffering from ascites more than 3 months after the delivery of her first baby, developed generalized edema, pyrexia, pleural effusion, and right lower abdominal pain. The laboratory data revealed 5.6 g of 24-hour urinary protein, increased ESR and CRP, a positive skin test for tuberculosis, and a positive culture fortuberculous bacilli from pleural effusion. A renal biopsy showed mild proliferative glomerulonephritis, IgA and C3 depositions along the capillary loop, in the mesangium and also in the focal tubular basement membrane, and scattered membranolysis of the glomerular basement membrane in addition to paramesangial and intramembranous electron-dense deposits. A positive culture of tuberculous bacilli led anti-tuberculous drugs resulted in the complete disappearance of proteinuria, inflammation, and various organ manifestations. As far as we know, the association of tuberculosis with glomerulonephritis is an uncommon occurrence. In addition to describing this case, we also discussed the role of tuberculosis in the pathogenesis of glomerulonephritis, and reviewed the pertinent literature.

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV01:26

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Nephrotic Syndrome I : Introduction

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 fluid...

Nephrotic Syndrome II : Assessment and Medical Management

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 any history...
