Există o predispoziţie genetică de a guttate psoriazis toate psoriazis. Psoriazisul estede asemenea, influenţată de mai mulţi factori de mediu.
Acesta nu este contagioasă şi nu este din cauza unei alergii. Exact ceea ce cauzează psoriazisul nu este pe deplin stiut, dar există o mulţime de cercetari active în acest domeniu.
Sistemul imunitar este implicat hiperactiv într-un mod care cauzează inflamaţiea. În mod specificexistă o producţie excesivă de TH1 citokineîn special TNF.

Apr 17, Author: Kirstin Altman, MD; Chief Editor: Dirk M Elston, MD more Manifestations, Management Options, and Mimicsa Critical Images slideshow, to help recognize the major psoriasis subtypes and distinguish them from other skin lesions. This variant of psoriasis primarily occurs on the trunk and the proximal extremities, but it may have a generalized distribution. Lesions usually spread centripetally and are monomorphic. New guttate psoriasis lesions continue to develop during the first month of disease; they remain stable during guttate psoriazis toate second month, and the remission begins during the third month.
Guttate psoriasis is more common in individuals younger than 30 years. An upper respiratory tract infection from group A beta-hemolytic streptococci eg, Streptococcus pyogenes often precedes the eruption by weeks. Although episodes may guttate psoriazis toate, especially those due to pharyngeal carriage of streptococci, isolated bouts have commonly been described. Generally, guttate psoriazis toate disease is self-limiting, but a certain percentage of cases progress to chronic plaque psoriasis.
The sudden appearance of the papular lesions in response to streptococcal infection could guttate psoriazis toate be the first manifestation of psoriasis in a previously unaffected individual or check this out acute exacerbation of long-standing plaque psoriasis.
For more information, go to Guttate psoriazis toate. The exact pathophysiologic mechanism in guttate psoriasis is undetermined. Guttate psoriasis is believed to result from an immune reaction triggered by a previous streptococcal infection in a genetically susceptible host.
Studies indicate the importance of chromosome 6 in determining the resultant psoriatic phenotype. Interactions of HLA-C with guttate psoriazis toate immunoglobulin—like receptors KIR on natural killer cells or natural killer T cells can be deregulated by streptococcal infection.
T lymphocytes and cytokines are believed guttate psoriazis toate cause the characteristic inflammatory changes guttate psoriazis toate on histopathologic examination of lesions. Psoriasis was guttate psoriazis toate classified as a Th1 disease, but Th17 cells have click the following article been recognized to have an important role.
Studies are also proposing a role for antimicrobial peptides and dendritic cells in the pathogenesis of psoriasis. Cathelicidin LL guttate psoriazis toate especially thought to lead to activation of dendritic cells, inducing production of interferons. Elevated levels guttate psoriazis toate the cathelicidin LL have been reported in patients with plaque and guttate psoriasis guttate psoriazis toate with healthy controls.
There was no significant difference in serum levels of inflammatory cytokines and LL between the plaque type and guttate psoriasis group, but guttate psoriazis toate positive correlation between disease activity and cytokine levels was noted. An autoimmune phenomenon has also been postulated to underlie guttate psoriasis because some streptococcal products and components have been found to cross-react with normal human epidermis.
Guttate psoriazis toate, Langerhans cell migration appears to be impaired during an acute episode of guttate psoriasis. International surveys on the guttate form of psoriasis among patients with psoriasis have found a wide range of prevalences, from 1. A study has shown that the prevalence of psoriasis correlates with the distribution and mortality of streptococcal epidemics. Guttate psoriasis is the second most common psoriasis variant in children. The onset more info the guttate psoriasis skin lesions often is acute, with multiple papules erupting on the trunk and the proximal extremities, guttate psoriazis toate a centripetal fashion.
Guttate psoriazis toate lesions are often accompanied by slight pruritus. In most cases of guttate psoriasis, a history of an antecedent streptococcal infection, usually of the upper respiratory tract eg, pharyngitis or tonsillitisweeks prior to the eruption can be elicited.
Multiple other infectious agents have been implicated, although episodes of guttate psoriasis attributed to them are not as frequent as those attributed to streptococci. Associated organisms include the following:. Drug therapy, including biologic agents, may sometimes precipitate a guttate-type flare. The most commonly implicated medications include lithium, beta-blockers, antimalarial drugs, and nonsteroidal anti-inflammatory guttate psoriazis toate. A positive family history of psoriasis may be present, and the outcome is generally good.
Examination of the skin reveals characteristic lesions consisting of multiple, discrete, mm in diameter, droplike papules with a salmon-pink hue. A fine scale, which is usually absent in early-stage lesions, may be appreciated on the more established ones, as shown in the image below. The lesions of guttate psoriasis appear first on the trunk and the proximal extremities, progressing in a centripetal fashion.
Lesions are commonly monomorphic and at the same stage of evolution. They may sometimes spread to involve the face, the ears, and the scalp. The palms and the soles are rarely affected. Nail changes in the form of pits, ridges, and the oil-drop sign, which are characteristic of chronic psoriasis, may be absent.
Additional findings may include pharyngeal or perianal erythema in cases associated with acute streptococcal infections. Ledoux et al emphasize a careful examination, including the perianal region, in children being examined for guttate psoriasis. The etiology of guttate psoriasis is not well understood. Genetic as well as environmental factors have been implicated in its pathogenesis.
As in other types of psoriasis, genetic predisposition seems to play an important role in the development of an acute http://pnkslm.net/medicamente-psoriazis-si-creme.php psoriasis flare.
Guttate psoriazis toate with control populations, a significant excess of HLA-BW17 has been found in patients with guttate psoriasis. Other researchers have found an increase in HLA-B13 positivity. Moreover, the inability to produce normal amounts guttate psoriazis toate antibody to streptolysin-O by HLA-B13—positive individuals might explain their high prevalence of guttate psoriasis. These patients experience psoriasis at markedly higher rates than control subjects. Thus far, psoriasis is the only disease associated with HLA-C gene expression.
Proteomic and immunohistochemistry studies have demonstrated that guttate psoriasis and chronic plaque psoriasis are phenotypically distinguishable in their protein expression patterns. The association of guttate psoriasis with streptococcal infection has been recognized for more than 50 years.
The streptococcal serotypes in these patients are similar to those seen in the general population. Aside from group A streptococci, Lancefield groups C and G streptococci have also been related to guttate psoriasis.
A number of cases in children have also guttate psoriazis toate triggered by streptococcal perianal cellulitis.
Presumably, absorption of streptococcal by-products occurs across the mucosa, as with pharyngeal infections. Unfortunately, although the association is definite, details regarding the exact mechanism by which streptococcal infection influences the formation of the psoriatic guttate psoriazis toate are still largely theoretical.
Histologic studies of early-stage psoriatic skin lesions reveal that the activation of T lymphocytes, endothelial cells, and macrophages guttate psoriazis toate epidermal proliferation. Indeed, group A streptococcal antigen—specific T lymphocytes, which secrete high levels of gamma link, can be consistently isolated from guttate psoriatic skin guttate psoriazis toate. Consistent with the role of T lymphocytes is the concept of superantigenic stimulation by certain streptococcal components or products.
Examples of superantigens produced by group A beta-hemolytic streptococci are streptococcal pyogenic exotoxins SPE types A, B, and C; a kd pepsin fragment of M type-5 protein; Guttate psoriazis toate pyogenes— derived cytoplasmic membrane—associated protein CAP ; and secretion-type CAP SCAP. It appears that patients with guttate psoriasis respond to group A streptococcal antigen presentation in the same way as nonpsoriatic patients.
However, the magnitude of their response is much greater. The fungus Malassezia furfur has been associated with the appearance of psoriatic lesions, but a causative role has not been proven. A study by Aydogan et al showed that the prevalence of M furfur was similar in patients with psoriasis and those without.
However, in psoriatic patients with M furfurcytokines important in the regulation of helper T-lymphocytes Th2 cellssuch as IL-4, IL, and IL, were markedly downregulated as compared to normal controls and psoriatic patients without M furfur. Thus, cytokine dysregulation appears to be important in the just click for source of psoriasis in this patient population.
Immunoblotting has demonstrated intense antistreptococcal antibody activity in the sera of patients with guttate psoriasis. Immunoglobulin G IgG antibodies against 3 different S pyogenes proteins—namely, aguttate psoriazis toateand a kd antigen—have been identified.
Indirect immunofluorescence studies of these antibodies showed that they react only with autologous skin in patients with guttate psoriasis and not with normal skin or lesional skin from patients guttate psoriazis toate do not have psoriasis. Autoantibodies in psoriatic sera may recognize certain structures in the transformed keratinocytes of affected psoriatic skin. These autoantibodies cross-react with streptococcal antigens. Cross-reaction has been demonstrated guttate psoriazis toate immunofluorescent microscopy by using a monoclonal antibody mAb to group A Am avut psoriazis cum a vopsi părul, which does not cross-react with antigens in normal human skin.
These antigens were associated with class 1M protein and were mostly concentrated in the dermal papillae around the capillaries and inside the cells of the epidermal basal layer. Epidermal Langerhans cell migration is inhibited in early-onset, plaque-type psoriasis.
Altered Langerhans cell migration has recently also been demonstrated in patients with guttate psoriasis. A small guttate psoriazis toate revealed decreased migration compared with healthy controls. In patients with resolved guttate psoriasis, the epidermal Langerhans cell guttate psoriazis toate was normal.
Guttate psoriazis toate the past years, concerns have been raised about vaccination as a possible trigger for new onset of psoriasis or exacerbation of existing disease. Several small studies have reported an association between influenza vaccination in the flu season and psoriasis. Tumor necrosis factor blocker therapy has been associated with the development or worsening of guttate psoriasis.
A careful history should be taken to exclude certain drugs, such as beta-blockers and lithium, which may cause an guttate psoriazis toate similar to that of guttate psoriasis. Viral exanthema should also be considered. Especially in patients with palmar and plantar lesions, serologic analysis should be performed to exclude secondary syphilis. Skin biopsy is probably the single most useful diagnostic test if the clinical diagnosis is not certain. Histopathologic findings and severity do not correlate with the clinical severity or the Psoriasis Severity Index.
Levels of antibodies to streptolysin O, guttate psoriazis toate, and deoxyribonuclease B may be elevated in more than half the patients with guttate psoriasis. Significant elevations of antistreptococcal M6 protein have been documented. Routine screening in asymptomatic patients is controversial. Patients with symptoms suggestive of a streptococcal infection should undergo appropriate laboratory testing.
A bacteriologic culture of the throat or the perianal area may be helpful to isolate the organism in selected cases. Throat culture continues to be the criterion standard to diagnose streptococcal pharyngitis. Urine results are usually negative. Detection of blood and protein on urinalysis could suggest a rare case associated with a concomitant poststreptococcal acute glomerulonephritis. However, reported cases have failed to prove association of psoriasis and poststreptococcal renal disease.
Because the clinical appearance is so characteristic, biopsy is seldom necessary to confirm the diagnosis of guttate psoriasis. Histopathologic changes may not be diagnostic when samples of early-stage papules are obtained at biopsy. The epidermis guttate psoriazis toate hyperplasia and small foci dafin tratament frunza psoriazis parakeratosis with an absence of the granular layer.
Dermal changes consisting of capillary dilatation and edema may be more pronounced, and an infiltrate consisting of lymphocytes and macrophages is seen mostly in the upper dermis. A few polymorphonuclear leukocytes may be found at all levels. Early lesions exhibit more inflammation and less acanthosis, and very early lesions can show normal basket-weave orthokeratosis overlying parakeratotic changes. In fully developed guttate lesions, vacuolated keratinocytes eventually disappear, leaving areas of agranulosis with overlying parakeratosis.
Degenerated polymorphonuclear leukocytes on an otherwise orthokeratotic stratum corneum may be the earliest presentation of Munro microabscesses. The term squirting papillae has been used to describe a phenomenon wherein neutrophils are discharged from the papillary capillaries, resulting in collections of neutrophils in association with parakeratotic mounds, as demonstrated in the image below.
In some cases, guttate psoriazis toate exudation may lead to the formation of the highly diagnostic spongiform pustule of Kogoj, which is seen in psoriasiform variants.
Histopathologic guttate psoriazis toate and severity do not correlate guttate psoriazis toate the clinical severity or Psoriasis Severity Index. Usually, guttate psoriasis guttate psoriazis toate resolves within a few weeks to months without treatment. In general, there is no firm consensus on specific treatment algorithms. As in other conditions, the choice of treatment should be tailored to the individual.
Should guttate psoriasis result as a reaction to a new medication, removal of the offending medication may be warranted if other treatments do not ameliorate the symptoms. Simple reassurance and emollients may be sufficient care.
Topical steroids can be effective but their application can be cumbersome, especially when the eruption is extensive, as it is guttate psoriazis toate most cases of guttate psoriasis. A guideline summary from the American Academy of Dermatology, Guidelines of care for the management of psoriasis and psoriatic arthritis: Overview of psoriasis and guidelines of care for the treatment of psoriasis with biologicsmay be helpful. Topical corticosteroids are a critical addition to the successful treatment of many guttate psoriasis patients.
The mechanisms believed to provide benefit include anti-inflammatory, antiproliferative, immunosuppressive, and vasoconstrictive effects. Seven potency classes of corticosteroids exist, and the agent prescribed should be selected from a class appropriate to the location of disease. Lower-potency corticosteroids should be used for face and intertriginous areas, areas of thinned skin, and on infants.
Higher-potency corticosteroids are generally acceptable in adults with lesions elsewhere on guttate psoriazis toate body. Thick plaques may require therapy with the most potent corticosteroids. Because of the clear association with streptococcal infection seen in most cases of guttate psoriasis, laboratory testing in patients with a known history or symptoms suggestive of streptococcal infections and antibiotic therapy have been proposed. However, the efficacy of guttate psoriazis toate in the management of psoriasis has been questioned guttate psoriazis toate data are limited.
Azithromycin, which is commonly prescribed for community-acquired pneumonia, is likewise an option. The clearance of guttate lesions can be accelerated by judicious exposure to sunlight or by a short course of either broadband ultraviolet B Inoculare psoriazisului or narrow-band UV-B phototherapy.
More resistant cases may benefit from oral psoralen plus exposure to ultraviolet A radiation PUVA. The suit PUVA technique guttate psoriazis toate been used in this setting.
Aside from the usual mechanisms by which UV light is believed to exert its beneficial effects in psoriasis, a specific fibrosing response to PUVA via increased mast cell activation has been observed in guttate psoriasis and might underlie the mechanism of action behind UV-induced resolution of the lesions.
However, considering the developments in photomedicine over the last several years, particularly regarding the clinical efficacy of narrowband UV-B phototherapy, versus the risk guttate psoriazis toate cutaneous malignancies with PUVA, treatment with narrowband UV-B is favored over treatment with PUVA.
Vitamin D analogues are also used for psoriasis. Randomized, placebo-controlled and double-blind studies have shown a marked improvement in disease as compared with response to other guttate psoriazis toate. Should guttate psoriasis prove resistant to the above therapies, it may develop into a chronic plaque psoriasiswhich may require systemic treatment with medications such as cyclosporine, acitretin, methotrexate, or a biologic agent.
Although unproven by large controlled clinical trials, tonsillectomy for patients with recurrent or chronic guttate psoriasis guttate psoriazis toate with poststreptococcal tonsillitis may be considered.
Physicians should watch for possible hypersensitivity reactions to the above-mentioned antimicrobials, especially to penicillin. If hypersensitivity is suspected, the drug should be immediately discontinued. Patients who are hypersensitive to penicillin generally do well on erythromycin. Cephalosporins can also cover streptococci, but some cross-sensitivity with penicillins has been documented.
Areas of the skin that have been treated with high-potency topical steroids for long see more may Sinel'nikov cauza psoriazisului some atrophy, telangiectases, and hypopigmentation. Shifting to a preparation with a lower potency or to another treatment modality should be considered. Patients on PUVA may experience a number of adverse effects, such as nausea and vomiting.
These effects are sometimes remedied by taking psoralen pills after a meal. The psoralen-induced photosensitivity persists up to 24 hours after administration of the drug.
Patients should be adequately informed about the need to wear protective lenses and to avoid sun exposure during this period. Patients should be advised to minimize all forms of skin trauma, such as scratching or vigorous rubbing, which may lead to new psoriatic lesions on previously unaffected areas Koebner guttate psoriazis toate. Learn more here should be advised to seek medical attention promptly for sore throat and other possible streptococcal infections.
Early detection and treatment of such infections may prevent an care sunt utile pentru uleiul de psoriazis flare of the skin disease. For patient education information, see the Psoriasis Centeras well as Guttate PsoriasisWhat Is Psoriasis? Guttate psoriasis is a nonfatal eruption that either can run a limited course over several weeks to a few months, may recur, or can develop into the chronic link of psoriasis.
Scarring is guttate psoriazis toate a problem. Previously affected areas may show postinflammatory hypopigmentation or postinflammatory hyperpigmentation. Data available on the prognosis of guttate psoriasis are sparse. Although guttate psoriasis often has a short-lived course, it may also represent the initial guttate psoriazis toate of chronic plaque-type psoriasis.
In a study of 15 patients, the probability of an individual developing chronic psoriasis within 10 years of a single episode of acute guttate psoriasis was suggested to be about 1 in 3, although further studies with larger numbers of patients are needed to more accurately click the risk.
Like other forms of psoriasis, guttate psoriasis tends to improve during the summer and worsen during the winter. Once an episode of acute guttate psoriasis has cleared, many learn more here will have limited or no evidence of psoriasis for prolonged periods. Vence L, Schmitt A, Meadows CE, Gress T.

Pathophysiology of Guttate Psoriasis The exact pathophysiologic mechanism in guttate psoriasis is guttate psoriazis toate. Clinical Presentation of Guttate Psoriasis Patient history The onset of the guttate psoriasis skin lesions often is acute, with multiple papules erupting on the trunk and the proximal extremities, in a centripetal fashion.
Bacteria - Staphylococcus aureus. Fungi - Malassezia, Candida. Viruses — Human papillomavirus HPVvaricella-zoster virus, [ 18 ] retroviruses, human endogenous retroviruses HERVs [ 19 ]. Etiology of Guttate Psoriasis The etiology of guttate psoriasis is not well understood. Diagnosis of Guttate Psoriasis Diagnostic considerations A careful history should be taken to exclude certain drugs, such as beta-blockers and lithium, which may cause an eruption similar to that of guttate psoriasis.
Serology Levels of guttate psoriazis toate to streptolysin O, hyaluronidase, and deoxyribonuclease B may be elevated in more than half the patients guttate psoriazis toate guttate psoriasis.
Cultures A bacteriologic culture of the throat or the perianal area may be helpful to isolate the organism in selected cases. Urinalysis Urine results are usually negative. Histologic Findings Because the clinical appearance is so characteristic, biopsy is seldom necessary to confirm the diagnosis of guttate psoriasis.

A Munro microabscess is present in the stratum corneum, underneath parakeratosis in center.
Neutrophils can be seen migrating through the psoriasiform epidermis, towards the guttate psoriazis toate the so-called squirting papillae hematoxylin and eosin, X. Overview of Treatment Usually, guttate psoriasis spontaneously resolves within a few weeks to months without treatment.
Corticosteroids Topical corticosteroids are a critical addition to the successful treatment of many guttate psoriasis patients. Antimicrobials Because of the clear association with streptococcal infection seen in most cases of guttate psoriasis, laboratory testing in patients with a guttate psoriazis toate history or symptoms suggestive of streptococcal infections and antibiotic therapy have been proposed.
