Summary
HIV-associated kidney disease presents with various symptoms. A higher CD4 cell count (≥200 cells/mm3) protects against chronic kidney disease and predicts better renal function in HIV patients.
Area of Science:
- Nephrology
- Infectious Diseases
- Immunology
Background:
- HIV infection is linked to diverse renal complications.
- Understanding the clinical and histological spectrum of HIV-associated nephropathy is crucial.
Purpose of the Study:
- To investigate the clinical and histological features of HIV-associated renal disease.
- To identify predictors of renal outcomes, including end-stage renal disease (ESRD) and death.
- To assess the impact of baseline CD4 T-cell count on chronic kidney disease (CKD) progression.
Main Methods:
- Retrospective evaluation of 61 HIV patients.
- Assessment of clinical presentation, renal histopathology, CD4 T-cell count, and viral load.
- Cox regression analysis to determine predictors of ESRD or death.
Main Results:
- Predominant histological findings included HIV-associated nephropathy (HIVAN) (28%), acute interstitial nephritis (AIN) (26%), and immune complex-mediated glomerulonephritis (ICGN) (25%).
- Non-nephrotic proteinuria (54%) and acute kidney injury (28%) were common presentations.
- A baseline CD4 cell count ≥ 200 cells/mm3 was a protective factor against CKD (HR=0.997, P=0.012) and associated with better estimated glomerular filtration rate (eGFR) at follow-up.
Conclusions:
- HIVAN, AIN, and ICGN are the primary histological lesions in HIV-associated renal disease.
- Kidney biopsy is recommended for HIV patients with renal impairment or proteinuria.
- Maintaining a CD4 cell count ≥ 200 cells/mm3 is vital for preserving renal function in HIV patients.

01:10Retrovirus Life Cycles
50.5K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

909
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

2.8K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

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...

01:25Chronic Kidney Disease I: Introduction
1.0K
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
