World Immunization Week
The last week of April each year is World Immunization Week. This year’s theme is “Immunization for all is humanly possible,” aiming to ensure that more children, adolescents, adults, and their communities are protected from vaccine-preventable diseases.
How to Strengthen Your Immune System
Enhance Innate Immunity
- Eat a varied diet: Aim for a diverse and balanced intake—more than 12 different foods per day and over 25 per week.
- Balance activity and rest, maintain a healthy weight: Reduce sedentary time. Get up and move every hour—any movement is beneficial.
- Quit smoking, limit alcohol; reduce sugar, oil, and salt: Keep daily salt intake under 5g, cooking oil at 25–30g, and sugar below 25–50g.
- Get enough sleep: Avoid staying up late. Adults should aim for 7–8 hours of sleep per night.
- Support mental health and manage stress: Recognize symptoms of depression and anxiety, and learn basic techniques for emotional and stress management.
- Maintain a healthy environment and proper protection: Improve personal hygiene habits and help keep your surroundings clean. Pay attention to indoor (home/car) and outdoor air pollution.
Enhance Acquired Immunity
- Vaccination: Vaccines stimulate antibody production and can provide protection ranging from months to decades. Examples include vaccines for pneumonia, influenza, COVID-19, HPV, hepatitis B, varicella-zoster (chickenpox/shingles), and rabies.
- Antibody therapy: Direct injection of antibodies against specific pathogens can offer temporary protection, such as monoclonal antibodies for respiratory syncytial virus (RSV) or rabies.
- Appropriate exposure: Avoid excessive cleaning and disinfection at home; use reasonable protection when going out. Engage with nature and everyday social environments—regular exposure to common microbes can help build immune resilience over time.
When the Immune System is Too Active
A weakened immune system usually means reduced defense, making the body more vulnerable to infections. But when the immune system is too aggressive, it may misidentify harmless substances as threats and attack them, leading to allergic reactions. These can show up as rashes, recurrent wheezing, rhinitis, sneezing, vomiting, or diarrhea.
In some cases, infections or other triggers can confuse the immune system, causing it to attack the body’s own healthy tissues and organs. This can result in autoimmune diseases such as rheumatic fever, systemic lupus erythematosus (SLE), Sjögren’s syndrome, rheumatoid arthritis, Hashimoto’s thyroiditis, autoimmune encephalitis, and dermatomyositis.
In short, a well-functioning immune system isn’t about being “stronger,” but about being balanced—able to defend against real threats without overreacting or turning against the body itself.
What are Autoimmune Diseases?
Autoimmune disorders arise when the immune system mistakenly attacks the body's own healthy tissues, leading to chronic inflammation, tissue damage, and a wide array of symptoms that can significantly impact physical and emotional well-being. Early serological screening plays a vital role in timely diagnosis, differential assessment, and monitoring disease activity or treatment response.
Overview of Key Autoimmune Diseases
| DISEASE | WHAT IT IS | KEY FEATURES/ AFFECTED SYSTEMS | KEY SEROLOGICAL MARKERS/ LABORATORY SUPPORT |
|---|---|---|---|
| 1. RHEUMATIC FEVER | An inflammatory complication following untreated group A streptococcal infection (e.g., strep throat). | ● Primarily affects the heart, joints, skin, and central nervous system. ● Presents with carditis, arthritis, chorea, erythema marginatum, and subcutaneous nodules. ● Diagnosis based on Jones criteria. | Elevated Anti-Streptolysin O (ASO) titers ● Indicates recent streptococcal exposure. ● Supports diagnosis alongside clinical criteria (Jones criteria). |
| 2. SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) | A chronic, multisystem autoimmune disease often involving skin, joints, kidneys, heart, and lungs. Features autoantibodies such as antinuclear antibodies (ANA). | ● Fluctuating disease activity. ● Can involve renal, cardiac, pulmonary, hematologic, neuropsychiatric, and mucocutaneous systems. ● Wide range of clinical presentations. | Laboratory Support ● Complement levels (C3, C4) may be low during flares. ● Immunoglobulins (IgG, IgA, IgM) can be elevated. ● Acute-phase proteins (e.g., CRP, ESR) reflect inflammation. |
| 3. SJÖGREN'S SYNDROME | Characterized by lymphocytic infiltration of exocrine glands, leading to dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia). Can occur alone (primary) or with other autoimmune diseases (secondary). | ● Extraglandular involvement may include skin, joints, lungs, kidneys, and nervous system. ● Chronic fatigue is common. ● Risk of lymphoma increased. | Serological Support ● Hypergammaglobulinemia (↑IgG, IgA, IgM). ● Autoantibodies: anti-Ro/SSA, anti-La/SSB (commonly assessed). ● Elevated ESR/CRP may be present. |
| 4. RHEUMATOID ARTHRITIS (RA) | The most common inflammatory arthritis, causing symmetric joint inflammation, potential erosions, and systemic effects. | ● Symmetric small joint involvement (hands, wrists, feet). ● Morning stiffness, swelling, and pain. ● Can involve extra-articular organs (lungs, eyes, vasculature). | Key Serological Markers Anti-Cyclic Citrullinated Peptide (Anti-CCP) antibodies ● Highly specific. ● Detectable years before clinical symptoms. Rheumatoid Factor (RF) ● Classic marker but less specific. |
How Goldsite’s Solution Supports Autoimmune Disease Screening?
Goldsite’s specific protein analyzers deliver quantitative, reliable results for key biomarkers in the autoimmune and inflammation panels.
GPP-100
Compact, cartridge-based, ideal for clinics and small-to-medium labs.
Aristo
High-throughput, fully automatic nephelometry system for medium-to-large labs.
Key Biomarkers Measured:
- Rheumatoid Arthritis: RF (Rheumatoid Factor), Anti-CCP (Anti-Cyclic Citrullinated Peptide) — highly specific for RA.
- Post-Streptococcal Conditions: ASO (Anti-Streptolysin O) — critical for post-streptococcal rheumatic fever.
- Immune System (supportive in SLE, Sjögren’s, and other systemic autoimmunity): IgA, IgE, IgG, IgM; C3, C4 — often decreased in active SLE.
- Inflammation & Acute-Phase Response — elevated in flares of RA, SLE, etc.: CRP, hsCRP, UsCRP, SAA, AAG, AAT, HPT, FR-CRP.
Accurate diagnostics complement immunization strategies by helping clinicians distinguish infection-related inflammation from autoimmune flares and supporting long-term patient management.
Protecting every generation means not only preventing disease through vaccines but also enabling precise diagnosis and care when the immune system needs support.
