[vc_row][vc_column width=»2\/3″][vc_column_text css=»»]Pruritus<\/strong>, commonly known as itching, is an unpleasant sensation that provokes the reflex to scratch. Despite extensive research, the mechanisms underlying pruritus are not fully understood, making it a continued subject of investigation. Scratching, a reflexive action to alleviate itching, can temporarily relieve acute pruritus.
\nHowever, in cases of chronic pruritus, this behaviour exacerbates the condition, leading to skin damage and worsening the itch-scratch cycle.<\/p>\n

Chronic pruritus is a complex phenomenon closely related to pain. It significantly affects the quality of life for both humans and animals, often leading to insomnia, depression, agitation, and anxiety.
\nGiven these profound impacts, significant efforts are dedicated to understanding pruritus and developing effective treatments.<\/p>\n

Types of Pruritus<\/h2>\n

Pruritus can be categorised into four types based on anatomical, physiological, and psychological factors:<\/p>\n

    \n
  1. Pruriceptive<\/strong> Pruritus:<\/strong> This type originates in the skin, triggered by sensory nerve endings responding to inflammatory mediators or skin damage. It is the most common type, associated with allergic, parasitic, or other skin disorders that alter normal skin conditions.<\/li>\n
  2. Neuropathic Pruritus: <\/strong>Caused by nerve damage in peripheral or central sensory neurons, this pruritus occurs without skin-related stimuli. Examples in veterinary medicine include acral mutilation syndrome, cauda equina syndrome, and pseudorabies.<\/li>\n
  3. Neurogenic Pruritus: <\/strong>Unlike neuropathic pruritus, this type results from central nervous system activation without nerve damage.
    \nIt is associated with systemic conditions such as liver disease or cancer and is less common in veterinary practice.<\/li>\n
  4. Psychogenic Pruritus: <\/strong>This type stems from psychological disorders, such as stress or depression. Diagnosed through exclusion of dermatological and neurological causes, it remains challenging to treat.Examples include psychogenic pruritus in cats or acral lick dermatitis in dogs.<\/li>\n
  5. Chronic Pruritus: <\/strong>Unlike acute pruritus, chronic pruritus induces hypersensitivity in the nervous system. Peripheral sensitisation reduces activation thresholds, increasing nerve density and responsiveness. Central sensitisation alters neuronal activity, causing non-itchy stimuli to evoke itching. These changes exacerbate the itch- scratch cycle, worsening inflammation and skin damage. These phenomena highlight the need for proactive treatment to prevent escalation of clinical signs.<\/li>\n<\/ol>\n

    Assessing Pruritus in Dogs and Cats<\/h2>\n

    Effective management of pruritus in dogs and cats requires an accurate assessment of it and its severity. Key steps in this process include:<\/p>\n

    Owner Observations: <\/strong>Owners provide valuable insights into their animal\u2019s condition, although these observations can be subjective. This information is gathered through anamnesis and pruritus assessment scales, with the most commonly used being the Pruritus Severity Scale by Rybn\u00ed\u010dek et al. (Fig. 1).<\/p>\n

    Physical Examination: <\/strong>A thorough physical examination helps identify lesions indicative of pruritus. Acute pruritus may present as excoriations, erythema, hot spots, or self-induced alopecia.
    \nChronic pruritus often manifests as lichenification, hyperpigmentation, traumatic alopecia, or eosinophilic granuloma complex lesions in cats.<\/p>\n

    Pruritus Reflexes: <\/strong>Evaluating reflex responses to stimuli, such as scratching or licking, helps pinpoint affected areas. Common reflexes include the pinnalpedal reflex (scratching triggered by stimulation of the auricular pinnae), the otic-pedal reflex (scratching in response to ear manipulation), and the trunk-pedal reflex.<\/p>\n

    Quality of Life Assessments: <\/strong>Quality of life scales assess the impact of pruritus on both the animal and its owner. These tools help evaluate how pruritus affects daily life, providing insights into the owners\u2019 concerns and the animal\u2019s well-being. They are also essential for making informed therapeutic decisions. Once pruritus has been identified and its severity assessed, the next step is to determine the underlying cause of the condition.[\/vc_column_text][\/vc_column][vc_column width=»1\/3″][vc_column_text css=»»]<\/p>\n\n\t\t\t
