Severe psoriasis: classification, features, aggravating factors, treatment.
Modern medicine does not completely cure psoriasis, but the symptoms of the disease can be alleviated at any stage. Moreover, a severe form of psoriasis requires immediate intervention by a dermatologist, since uncontrolled complications can lead to the death of the patient.

Each disease in medical practice has its own nomenclature number, which is established according to the ICD-10 international system. This number designation indicates typical signs of the disease. For psoriasis, this is L40 and an additional value after the point (for example, L40.3).
There are such types:
L0 – common form of psoriasis;
L1 – generalized pustular psoriasis;
L2 – persistent acrodermatitis;
L3 – psoriasis of the feet and inner side of the palms;
L4 – teardrop-shaped psoriasis;
L5, L6, L7 – forms of arthropathic psoriasis affecting the joints;
L8 – other forms;
L9 – undefined type;
There are also 2 more international classification systems: the US National Medical Fund and the international PASI index. The first determines the disease depending on the extent of damage to the skin and is considered insufficiently complete (does not classify information about the degree of spread or relative to the course of the disease).
It has only three points:
The international PASI index relies in its classification on the following factors:
Information on the international index is systematized in an extensive table with several sections. This allows you to determine the type of psoriasis more accurately and prescribe the correct treatment.
Also, this disease, depending on the form, is divided into two large groups:
But there are also types of psoriasis that are not included in the main groups. Among them:
Psoriasis can be mild or severe in severity. The latter is characterized not only by skin lesions, but also by systemic manifestations (for example, the development of joint arthritis).
Types of severe forms of psoriasis and their features.
With a severe form of this disease, damage to the skin is at least 5%. Psoriasis affects the joints and nail plates, and secondary infections and other systemic manifestations may also occur.
Most often, this form occurs in those who have been diagnosed with one of the following diagnoses: obesity, diabetes mellitus, thyroid disease, disorders of the endocrine system as a whole, and any malfunctions in the immune system.
A feature of the exudative type is the appearance of scales with a loose structure on the surface of psoriatic plaques. The flakes themselves form a continuous crust of yellow color, saturated with exudate, and their edges are hyperemic.
This form is characterized by burning, intense itching and inflammatory processes. After removal of the yellow peel, the active secretion of exudate begins, and the surface of the papules becomes moist and bleeding.
It affects the skin of the palms and feet, while it can be localized or generalized. The pustular form usually accompanies ordinary psoriasis and is characterized by the presence of purulent segments.
The cause of this type of disease can be:
A local variety of the pustular form is called the “Barber type” and is characterized by the appearance of purulent rashes on the arch of the foot, palms or sole. The development mechanism is as follows: first red spots appear, in the place of which pustules with transparent contents appear over time. Within a few days, the contents of the vesicles become purulent.
During the progression of the disease, some pustules dry out and become covered with a brown crust, and new vesicles form in place of other red spots. The peculiarity is that pustular elements are recessed into the skin, as it were, and do not rise above its surface.
This severe form of psoriasis develops due to improper treatment of vulgar psoriasis and is a complex toxic and allergic skin reaction. But a complication of this type can also provoke other external factors:
The first stage of erythroderma is characterized by redness of the skin and a feeling of tightening. Then there is a burning sensation, severe itching, and pain. Puffiness of the skin, peeling is manifested. The patient’s condition deteriorates sharply: the temperature rises, the lymph nodes increase, the joints begin to hurt.
With the development of the disease, symptoms of general intoxication intensify: the patient complains of debilitating headaches, indigestion, general weakness. Erythroderma accompanying psoriasis is one of the most dangerous complications that can lead to the death of a patient. The generalized inflammatory process of extensive lesions leads to skin exfoliation. If secondary infection occurs in this situation, then this threatens with sepsis and subsequent death of a person.
How to determine the severity of the disease?
Only a dermatologist can determine the degree and form of psoriasis. To do this, he conducts a thorough examination of the skin, scalp, nails, mucous membrane. In some cases, a biopsy is required (a skin sample is taken for examination under a microscope).
Also, the doctor must know the patient’s complaints and compare what he heard with the results of the examination. When examining, it is important to determine the following factors:
After collecting information about the psoriatic rash, the doctor compares it with data from international classifications. There are 3 degrees of severity of the disease:
What is the danger of severe psoriasis with complications?
As a chronic dermatological disease, psoriasis occupies one of the leading positions. Its complications are dangerous in that joints and vital internal organs are involved in the pathological process: heart, kidneys, liver and vascular system.
When psoriasis becomes severe, the patient loses the ability to perform daily work, take care of himself, go to work. In this case, we can talk about assigning him the category of disability.
In addition, serious psychological problems develop. This is typical for those cases when lesions are located in open areas of the body (face, hands, head). Significant physiological and psychological discomfort is caused by a disease localized on the genitals, which interferes with normal sex life. The severe form of psoriasis in the photo looks depressing, but in life it causes discomfort.
All these factors lead to impaired social adaptation, the patient becomes confident in his unattractiveness, neurosis, prolonged depression, suicidal tendencies are manifested. In this case, be sure to contact a specialist.
A distinctive feature of the disease is the wave-like nature of its course. This means that the symptoms worsen during the period from late autumn to early spring and decrease in summer. In addition to temperature and humidity indicators of the environment, the following factors can influence the exacerbation of the condition:
The most common cause of psoriasis becoming the most severe is the failure to follow the doctor’s recommendations or the wrong therapy. It is important to determine the correct treatment at an early stage.
For a correct diagnosis, it is important to take into account the following points:
Therefore, dermatoscopy may not be enough to make a correct diagnosis. In such cases, a skin biopsy is performed, the results of which can provide a histological picture. These data are correlated with clinical manifestations and any laboratory tests.
Treatment of severe psoriasis
To date, there are no such treatments that would completely get rid of any of the severe forms of psoriasis. Therapy in this case is represented by a number of drugs that help reduce the intensity of symptoms, prolong the period of remission and strengthen the immune system.
In case of complications, complex treatment will be used, including the use of internal and external agents:
