Insights

Pediatric immune reconstitution inflammatory syndrome (IRIS) affects 38% of HIV-infected children in Uganda, often presenting early after antiretroviral therapy (ART) initiation. Key risk factors include low pre-ART CD4 counts and male sex, necessitating increased awareness among healthcare providers and caregivers.

Area of Science:

  • Pediatric Infectious Diseases
  • Immunology
  • Global Health

Background:

  • Immune reconstitution inflammatory syndrome (IRIS) is a significant concern in children initiating antiretroviral therapy (ART), particularly in resource-limited settings.
  • Understanding the clinical patterns and prevalence of pediatric IRIS is crucial for effective management.

Purpose of the Study:

  • To determine the clinical pattern, prevalence, and associated factors of pediatric IRIS in Uganda.
  • To identify risk factors for IRIS in HIV-infected children starting ART.

Main Methods:

  • A prospective, multicenter cross-sectional study was conducted in Uganda.
  • 162 HIV-infected children receiving ART for 0.5-6 months were evaluated for IRIS using a standardized case definition.

Main Results:

  • The prevalence of IRIS was 38%, with 77% being unmasking of new opportunistic infections.
  • Tuberculosis-IRIS was the most frequent presentation (29%), often occurring within the first month of ART.
  • Independent risk factors included low pre-ART CD4(+) cell percentage, high current CD8(+) cell count, male sex, and prolonged cough.

Conclusions:

  • IRIS is common in Ugandan children with advanced immunosuppression starting ART, frequently occurring early in treatment.
  • Awareness of IRIS among healthcare providers and caregivers is essential to prevent ART nonadherence and improve patient outcomes.

Immunodeficiency Diseases

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.
There are three main causes of immunodeficiency disorders...

Inflammatory Bowel Disease IV: Clinical Manifestations

Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Acute Kidney Injury III: Clinical Manifestations

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...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
