IgA nephropathy
The characteristics of proteinuria in IgA nephropathy
IgA nephropathy is a pathological type of chronic glomerulonephritis, which can cause patients to exhibit symptoms such as proteinuria and hematuria. Regarding the characteristics of proteinuria, it is generally primarily glomerular proteinuria. In the classification of patients' proteinuria, glomerular proteinuria accounts for a large proportion. If IgA nephropathy presents as chronic nephritis or nephrotic syndrome, the patient's level of proteinuria will be quite severe, with significant amounts of proteinuria, where the 24-hour urinary protein quantification may exceed 1g or even reach more than 3.5g. However, not all patients with IgA nephropathy have such high levels of proteinuria; some may only have mild proteinuria.
Is IgA nephropathy sexually transmitted?
IgA nephropathy, a type of chronic glomerulonephritis, does not transmit through sexual intercourse. This condition involves a sterile inflammatory response within the glomeruli of the kidneys, not caused by pathogens such as bacteria, viruses, or fungi. Instead, it results from an immune dysfunction, causing inflammation in the glomeruli without any infectious agents. Therefore, IgA nephropathy is not contagious, and sexual intercourse does not pose a risk of transmitting the condition to a sexual partner. As such, patients with IgA nephropathy can engage in sexual activities if their physical condition permits.
Can patients with IgA nephropathy have sexual intercourse?
Patients with IgA nephropathy can engage in sexual intercourse, but there are certain prerequisites. Firstly, this disease is not contagious, and it will not be transmitted to the partner during intercourse. Secondly, there is not a significant relationship between renal function and sexual capability; patients with kidney diseases typically retain normal sexual and reproductive functions. However, since sexual activity requires a certain amount of physical strength, and in cases where the patient's condition is particularly severe, it might render the patient unable to engage in sexual activities. Therefore, if the patient does not have significant hypertension, severe edema, especially genital edema, pulmonary edema, or heart failure, they would be capable of engaging in sexual activities, and thus can have intercourse.
Why doesn't IgA nephropathy cause swelling?
IgA nephropathy refers to the abnormal deposition of IgA immunoglobulin in the glomeruli of patients, which causes an inflammatory response and damages the glomerular capillaries. The extent of this damage varies, so not all patients will experience swelling. If the condition is severe, causing significant proteinuria, patients may develop hypoproteinemia and consequent decrease in plasma colloidal osmotic pressure, leading to swelling. If renal failure has occurred, the kidneys' ability to excrete water decreases, which can also cause swelling. Some patients may experience swelling due to damage to the renal tubules, which increases the reabsorption capacity for water. Otherwise, patients may not show obvious swelling, such as those with only mild proteinuria and hematuria, whose clinical symptoms are not pronounced.
IgA kidney disease causes
IgA nephropathy is a type of chronic nephritis. Patients with this disease have inflammatory reactions within their glomeruli. This inflammation is caused by the deposition of IgA immune complexes in the glomeruli. The reason why patients are prone to IgA immune complex deposition is still not very clearly explained in current medical literature and remains unclear. It is possible that such patients produce defective IgA immunoglobulins, often related to mucosal inflammatory infections, such as tonsillitis, enteritis, proctitis, etc. Inflammation of these mucosal areas might cause defective secretory IgA to circulate through the bloodstream to the kidneys, triggering an inflammatory response. The production of defective IgA immunoglobulins in patients may be related to genetic and environmental factors, but the specific mechanism is still not very clear.
