AddThis It is also known as acute generalised pustular psoriasis of von Zumbusch. . Epub Mar 5. Pustular psoriasis is an uncommon form of psoriasis consisting of widespread pustules on an erythematous background, as shown in the.

This is due to recessive IL36RN gene mutations.

These mutations are also found in some patients with AGEP , palmoplantar pustulosis and acrodermatitis continua of Hallopeau. In these patients, CARD14 gene gain-of-function abnormalities have been reported.

Possible trigger factors for flares of generalised pustular psoriasis may include: Sudden withdrawal of injected or oral corticosteroids Drugs such as lithium , aspirin, indomethacin, iodide and some beta-blockers Infection. Generalised pustular psoriasis sometimes arises in pregnancy.

Generalized pustular psoriasis: a review and update on treatment.

Previously known as impetigo herpetiformis, this name is no longer favoured because the eruption has nothing to do with either impetigo a bacterial infection or herpes simplex a viral infection. Strong, irritating topical preparations such as coal tar , dithranol and withdrawal of strong topical corticosteroids can lead to localised areas of pustulosis, often associated with existing plaques of psoriasis.

What are the signs and symptoms of generalised pustular psoriasis? Generalised pustular psoriasis is characterised by recurrent acute flares.

As such, histopathologic examination of all variants reveals parakeratosis, extensive mononuclear and neutrophilic inflammatory infiltrate in the epidermis, and epidermal edema and hyperplasia. However, recent research indicates that acute GPP and plaque psoriasis are genetically distinct conditions without a common pathophysiologic mechanism. The pustules often expand and coalesce, forming lakes of pus.

Notes: Innumerable pustules studded on a background of erythematous plaques on the chest, abdomen, and upper arms. Some areas of pustules have coalesced into large plaques of crust on the lower abdomen. The mean age at onset of acute GPP is Acute withdrawal of systemic corticosteroids can lead to an acute inflammatory process acting as a trigger for acute GPP. Activation of ILR within these cells leads to activation of inflammation within the skin and development of the clinical features of inflammatory skin conditions, specifically GPP.

GPP and its important genetic association with ILRA deficiency has also been shown to exhibit a gene dosage effect. Another study regarding the various possible genetic mutations associated with GPP was conducted in nine children from six families who presented with neonatal sterile osteomyelitis, periostitis, and generalized pustulosis.

This study discovered the condition present in these children was linked to a genetic mutation involving IL1RN, which encodes the IL-1 receptor antagonist.

Guidelines published in by the Medical Board of the National Psoriasis Foundation recommend acitretin, cyclosporine, or methotrexate to be the first-line therapies for acute GPP Table 1. One study described the efficacy in nine of ten patients with acute GPP who experienced results within 24 hours to 7 days of the first treatment. The recommended second-line therapies include adalimumab, etanercept, psoralen plus ultraviolet-A PUVA phototherapy, topical corticosteroids, topical calcipotriene, and topical tacrolimus, or combination therapy for recalcitrant disease which includes a first-line oral systemic agent plus a biologic agent such as adalimumab or etanercept.

If necessary, however, they may be used in circumstances in which other therapeutic options are not available. However, the classification of this dermatitis as a disease distinct from pustular psoriasis is still debated, and in various studies, it continues to be discussed as impetigo herpetiformis. Some publications, however, report the occurrence as early as the first month of pregnancy.

Potential triggers include increasing levels of progesterone during the last trimester of pregnancy, hypocalcemia, and lower levels of elafin, an epidermal skin-derived antileukoproteinase, which may all contribute to the production of epidermal pustules. Pregnancy has been noted as a precipitating factor for the new development or acute flare of GPP. In terms of therapeutic options, systemic corticosteroids are widely accepted to be the most commonly used first-line treatment for pustular psoriasis of pregnancy Table 2.

As mentioned, delivery of the fetus often results in rapid resolution of the dermatitis, which should be considered in cases of severe disease despite optimal medical management. First-line therapy for this disease is similar to that of pustular psoriasis in adults.

Clinical and genetic differences between pustular psoriasis subtypes.

Acitretin, cyclosporine, etanercept, or methotrexate can each be used safely as first-line therapeutic options in children with pustular psoriasis Table 3.

Localized pustular psoriasis: This form can be stubborn to treat.

Topical treatments are usually prescribed first. Von Zumbusch: Treatment often consists of acitretin, cyclosporine or methotrexate.

Some doctors may prescribe oral steroids for those who do not respond to other treatments or who have become very ill, but their use is controversial because sudden withdrawal of steroids can trigger von Zumbusch pustular psoriasis. PUVA may be used once the severe stage of pustule development and redness has passed.

Pustular Psoriasis

Palmoplantar pustulosis: Because PP often is stubborn to treat, doctors usually prescribe topical treatments first, and then consider other options, including PUVA, UVB, acitretin, methotrexate or cyclosporine. Acropustulosis: Traditionally this form of pustular psoriasis has been hard to treat.

Occlusion of topical preparations may help some people. Some people have had success using systemic medications to clear lesions and restore the nails.

Occlusion of topical preparations may help some people. In these patients, CARD14 gene gain-of-function abnormalities have been reported.

Generalized pustular psoriasis GPP is a subtype of pustular psoriasis characterized by painful and occasionally disfiguring cutaneous manifestations with sepsis-like systemic symptoms. Systemic symptoms Flares of generalised pustular psoriasis may result in: Fever and chills or hypothermia A headache Loss of appetite and nausea Thirst and dehydration Muscle weakness Leg swelling.

Generalised pustular psoriasis is characterised by recurrent acute flares.
