Chronic Kidney Disease II: Clinical Manifestations

444
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...

Endocarditis II: Clinical Features of Infective Endocarditis

261
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Gastritis III: Clinical Manifestations and Management

986
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Inflammatory Bowel Disease I: Ulcerative Colitis

744
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Autoimmune Disorders

1.3K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Area of Science:

  • Pediatric Rheumatology
  • Nephrology
  • Dermatology

Background:

  • Immunoglobulin A vasculitis (IgAV), also known as Henoch-Schönlein Purpura, is a common systemic vasculitis in children.
  • It involves small blood vessels, leading to diverse symptoms across multiple organs.

Purpose of the Study:

  • To review and synthesize data on the various systemic manifestations of IgAV.
  • To enhance understanding for improved diagnosis and management of this condition.

Main Methods:

  • A comprehensive literature search was conducted in the PubMed database.
  • MeSH terms "IgA vasculitis" and "Henoch Schönlein Purpura" were utilized for data retrieval.
  • Extracted data were sorted according to a predefined manuscript structure.

Main Results:

  • The most common clinical presentations include palpable skin purpura, arthritis, gastrointestinal involvement, and kidney damage.
  • Less common manifestations encompass neurological symptoms, scrotal involvement, and cardiopulmonary disease.
  • Misdiagnosis of rare complications can delay treatment and negatively impact prognosis.

Conclusions:

  • Comprehensive awareness of IgAV's clinical spectrum is crucial for timely diagnosis.
  • Prompt diagnosis and appropriate treatment are essential for achieving optimal patient outcomes.
  • While often self-limited, recognizing diverse IgAV manifestations prevents diagnostic delays.
