What is Guttate Psoriasis?

Guttate psoriasis is a type of psoriasis characterized by the eruption of tear-drop like papules in salmon-pink color and fine scales over the affected skin. The lesions of guttate psoriasis usually develop in the areas of the proximal extremities and the upper trunk but may also have a generalized distribution.


Guttate psoriasis is also referred to as Eruptive psoriasis and is often preceded by a streptococcal infection. It is a type of psoriasis that equally affects both male and female regardless of racial group. It is also regarded as the second most common type of psoriasis that can affect children as it usually occur in children and individuals under the age of 30 years. In general, however, guttate psoriasis is rather rare.

Guttate psoriasis is a variant of psoriasis where the latter is described as a chronic skin condition characterized by the development of thick and scaly patches of skin that may be reddish, whitish or silvery in color and is the result of rapid growth of skin cells. Guttate psoriasis is among the variant of psoriasis and next to plaque psoriasis which is regarded as the most common type of psoriasis. Guttate psoriasis is potential to develop into plaque psoriasis but the reddish and scaly lesion may completely heal without the need for treatment.

Guttate Psoriasis Symptoms

Guttate psoriasis is a non-fatal eruption of the skin that occurs acutely and develops in the areas of proximal extremities and the trunk. Prior to the onset of guttate psoriasis, it is preceded by a streptococcal infection usually of the upper respiratory tract such as pharyngitis and tonsillitis. Guttate psoriasis often follows within 2 to 3 weeks after the streptococcal infection has resolved.

The onset of lesion is acute and often with multiple lesions appearing on the proximal extremities and on the trunk. The lesions, however, may extend or spread to the face, scalp and ears. Itching or mild pruritus is often associated with guttate pruritis. Guttate psoriasis is noticeably worse during the cold or winter months and improves during the summer months just like the condition of psoriasis.

At closer look, the characteristics of the lesion in guttate psoriasis include the following:

  • Multiple papules that are about 1 mm to 10 mm in diameter
  • The papule is tear-drop or drop like in shape
  • The papule is salmon-pink or reddish in color
  • Fine scales are usually absent during the early stage of the lesion and become more apparent as soon as it become established

There may be no presence of changes in the nails such as pits and ridges which are characteristics of chronic psoriasis. The palm of the hands and the sole of the feet are usually spared from the lesions brought by guttate psoriasis.

Causes

Guttate psoriasis is believed to be influenced by different factors. The exact manner on how these factors trigger the onset of guttate psoriasis however remains unclear.

The factors considered to trigger the onset of guttate psoriasis include the following:

  • Genetic factor is believed to play an important role to the onset of guttate psoriasis just like any other psoriasis. HLA-BW17 and HL-B13 genes are being linked to the incidence of guttate psoriasis. The exact mechanism of these genes in reacting towards the other microorganisms and molecules to produce guttate psoriasis remains unclear.
  • Streptococcal infection is the most implicated in the onset of guttate psoriasis. Streptococcal infection of the upper respiratory tract infection in particular is the most linked to guttate psoriasis and has been recognized in the medical field for more than 5 decades. It is a precedent to guttate psoriasis where the eruption of skin usually occurs within 2 to 3 weeks after streptococcal infection such as pharyngitis and tonsillitis have subsided.
  • Viral infection is also believed to trigger the onset of guttate psoriasis. Chickenpox, Roseola and rubella are some of the viral infections known to trigger guttate psoriasis in children, although the exact mechanism is still unclear.
  • T lymphocyte activation through the production of cytokines is also considered a factor in influencing the proliferation of skin lesions in guttate psoriasis. The activation of T lymphocytes precedes the onset of guttate psoriasis.
  • Medications or drugs are also among believed to trigger epidermal proliferation in guttate psoriasis. Drug for tumor necrosis factor blocker is being linked to the onset and worsening condition of guttate psoriasis.

Treatment

Guttate psoriasis is a form of psoriasis that usually resolves within several weeks without the need for treatment.

A broad spectrum antibacterial medication may be given to treat the infection subsequently guttate psoriasis. Erythromycin acts as anti-inflammatory and anti-bacterial that this medication is often prescribed for the treatment. Rifampin is specially indicated for resistant streptococcal infection. It is often used in combination with Erythromycin or Penicillin and is taken orally for a period of five days. Penicillin is another medication for the treatment of guttate psoriasis although special precaution must be taken as it is contraindicated for those with allergic reaction to penicillin treatment.

Gluten-free diet is found to be beneficial in patients suffering from guttate psoriasis. There has been no clear study to prove this type of diet but many patients particularly those with gluten intolerance found a gluten-free diet to be beneficial in diminishing the inflammation and other symptoms of guttate psoriasis.

Vitamin C, vitamin E, vitamin A and zinc are rich in antioxidants and fatty acids that are essential nutrient for the skin and especially help in the treatment and prevention of guttate psoriasis. These nutrients can be acquired by eating fruits, nuts, vegetables, seeds and legumes.
