What is Urticaria?
Urticaria also called as hives,It is a skin condition in that occuring some raised and itchy welts or bumps on the skin. These welts are typically red or skin-colored and can vary in size. Urticaria occurs when the body's immune system releases histamine and other chemicals, leading to swelling and inflammation of the skin.
What are the Symptoms of Urticaria ?
• Raised Weals
• Itching
• Swelling
• Burning Sensation
• Duration
1. Raised Weals:-Raised weals are red, itchy welts that can occur anywhere on the body.They may vary in size and shape, can be round, ovoid, or irregular, and most often appear suddenly.The raised areas result from fluid leakage into the dermis due to the release of histamines and other chemicals from mast cells during an allergic reaction or other triggers. You can raised above the surface of the skin, giving them a bump-like appearance.They have typically red or skin-colored.
2. Itching:- Itching, or pruritus, is one of the hallmark symptoms of urticaria and is caused by the release of histamines and other inflammatory mediators.The intense itching is a direct result of the body’s immune response causing nerve endings in the skin to become more sensitive. Scratching can prevent by temporary relief but can lead to skin damage, secondary infections, or worsening of the hives.
3.Swelling:- In addition to hives, swelling can occur in affected areas, referred to as angioedema, which is a deeper form of swelling compared to the surface welts. This can affect areas such as the face, lips, tongue, throat, hands, and feet.Swelling may last longer than the raised welts and can be painful or tender in some cases.
4.Burning Sensation :- Some individuals with urticaria may experience a burning sensation in addition to itching. This symptom also arises due to the inflammatory mediators released during the allergic reaction, which can irritate sensory nerve endings.The burning may be described as a hot, tingling pain, and can sometimes feel like mild stinging.
5.Duration:- The duration of urticaria symptoms can vary significantly from person to person and depends on the type (acute or chronic) of urticaria. Acute urticaria may last less than six weeks, while chronic urticaria persists for six weeks or longer and can be recurrent.Symptoms may appear and disappear suddenly, often presenting in flare-ups that can last a few hours to several days.
What are the causes of Urticaria?
• Allergic Reactions
• Infections
• Physical Triggers
• Stress
• Chronic Conditions
1) Allergic Reactions:-Allergic reactions are among the most well-known triggers of urticaria. They occur when the immune system overreacts to normally harmless substances (allergens).This release causes the characteristic raised welts, itching, and inflammation seen in urticaria.Antibiotics (like penicillin) and non-steroidal anti-inflammatory drugs (NSAIDs) can trigger reactions.
2) Infections:- Viral infections are a common underlying cause of urticaria, especially in children. Bacterial and fungal infections can also be triggers. The body’s immune response to infections might cause systemic inflammation, which can exacerbate urticaria in susceptible individuals.Upper Respiratory Infections: Often associated with acute cases of urticaria. Conditions like hepatitis or infections with specific bacteria (e.g., strep throat) may trigger chronic urticaria.
3) Physical Triggers: Physical factors can induce urticaria in some individuals, termed physical urticaria.Exposure to extreme temperatures (heat, cold) can lead to cold urticaria or heat-induced urticaria.Some people experience hives with sun exposure.Physical activity can induce symptoms, often referred to as exercise-induced urticaria.
4) Stress :- Psychological stress is recognized as a significant, albeit indirect, trigger for urticaria.Stress can stimulate the release of hormones such as cortisol and adrenaline, which may influence mast cell activity and mediators involved in allergic reactions.While stress might not directly cause urticaria, it can exacerbate existing conditions or cause flare-ups in individuals already predisposed to hives.
5) Chronic Conditions :- Certain chronic conditions can predispose individuals to develop urticaria or exacerbate existing symptoms.Conditions like lupus or thyroid disease are linked to chronic urticaria.Chronic infections may trigger ongoing urticaria. Persistent infections,including those caused by hepatitis or intestinal parasites, can trigger urticaria. Skin disorders, like eczema , can also be associated with urticaria .
What is Main Diagnoses for Urticaria ?
• Clinical Examination
• Allergy Testing
• Drug History Review
• Chronic Urticaria Assessment
• Exclusion of Related Conditions
1.Clinical Examination :-The clinical examination is vital in diagnosing urticaria and involves a detailed history and physical assessment.Patients are asked about the onset, duration, distribution, and characteristics of the hives. The physician examines the skin for raised welts (wheals), erythema, and patterns of distribution.Evaluating the impact of urticaria on the patient’s quality of life, including sleep disturbances, work, and emotional well-being.
2.Allergy Testing :- Allergy testing is used to identify environmental, food, or other allergens that may trigger urticaria.Small amounts of allergens are introduced through the skin to observe for reactions.Measures the levels of IgE antibodies to specific allergens in the blood.Positive allergy tests can provide clear guidance for avoiding specific allergens, while negative results can help steer the evaluation in other directions.
3.Drug History Review :- A comprehensive review of the patient’s medication history is vital in uncovering drug-induced urticaria.Timing Correlating the onset of hives with recent medication changes can help identify drug-induced triggers. NSAIDs, antibiotics, ACE inhibitors, and certain medications for diabetes are often implicated.
4. Chronic Urticaria Assessment :-
Chronic urticaria lasts longer than six weeks and can be difficult to manage.Chronic urticaria can be classified into chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIU).Each type may require different management strategies.
5.Exclusion of Related Conditions :-Exclusion of other medical conditions is a crucial step, especially with chronic urticaria.Autoimmune Disorders such as lupus or thyroid disease can be linked to hives.Chronic infections such as hepatitis or Helicobacter pylori may contribute to symptoms.
