Tratamento da Pitiríase rósea

Por Dr. Fernando Matos, MD

Pitiríase rósea é uma doença de pele que se manifesta com lesões de pele amplamente distribuídos que são vermelha, escamosa e muitas vezes coceira. A condição geralmente afeta pessoas entre idade 10 e 40 anos e é ligeiramente mais comum entre mulheres do que homens.

Na maioria das pessoas que a condição se resolve por si só dentro de 4 a 8 semanas ou mais de doze semanas ou três meses, tempo e nenhum tratamento específico é necessário. Os tratamentos visam principalmente aliviar os sintomas como coceira ou corretas infecções bacterianas secundárias ou outras complicações. 1-7

Tratamento da Pitiríase rósea inclui hidratantes de pele ou emolientes, cremes contendo corticosteróides e assim por diante.

Hidratantes de pele ou emolientes

Estes são os cremes de pele que são direcionados para hidratar ou acalmar a pele sobre as lesões. Isso leva ao alívio da coceira. Estes estão disponíveis como pomadas, loções também.

Em algumas pessoas os sabonetes com hidratantes também podem ser prescritos. Sabonetes normais causam irritação e empobrecem a camada de óleos sobre a pele, devido à sua dureza. Pacientes podem ser aconselhados a evitar estes sabonetes e usar sabonetes com hidratante superior ou conteúdo emoliente. Estas podem ser aplicadas com a freqüência necessária para aliviar a coceira e evitar o ressecamento da pele.

O hidratante ou o emoliente deve ser aplicado suavemente na direção do crescimento do cabelo e fricção vigorosa deve ser evitada.

Cremes contendo corticosteróides

Esses medicamentos são destinados a reduzir a inflamação sobre as lesões. Estes precisam ser prescritos pelo médico para a maioria das pessoas. Corticosteróides são prescritos se emolientes não mostrar a eficácia. Estas são essencialmente uma forma sintética de hormônios produzidos pela glândula adrenal no corpo humano. Eles agem reduzindo a coceira causada por inflamação e vermelhidão.

Os cremes devem ser aplicados levemente para as áreas afetadas da pele uma ou duas vezes por dia. Cremes esteróides não são prescritos para mais de uma semana e geralmente aconselha-se uma dose média. Isso é porque eles podem levar a complicações como queima-se da inflamação, se parou abruptamente. Além disso, algumas pessoas podem sentir um ligeiro ardor ou a sensação pungente quando eles aplicarem a medicação. Isso geralmente é um efeito temporário de lado e vai embora com o tempo.

Anti-histamínico contendo comprimidos

Estes são medicamentos anti-alérgicos que podem aliviar a coceira. Os medicamentos mais comuns desta classe são Hydroxyzine ou clorofenamina.

Os anti-histamínicos de primeira geração como clorofenamina causam sedação e sonolência e foram usados anteriormente para as alergias. Estes podem ajudar na Pitiríase rósea, como eles ajudam os pacientes a dormir melhor. No entanto, pacientes são aconselhados a não para conduzir ou operar máquinas enquanto estiver usando este medicamento. Os agentes mais novos geralmente não causam sedação, mas aliviar a coceira.

Terapia de luz ultravioleta b

Se os pacientes não respondem à terapia comum que podem ser recomendadas para a terapia de luz UV B. Isso envolve controlado expondo a pele afetada por alguns minutos em intervalos regulares para os raios UV B sob supervisão de um dermatologista ou um especialista da pele. Exposição à luz solar natural também pode ser útil, mas devem-se evitar queimaduras de sol e exposição aos raios do sol também pode levar a um maior risco de câncer de pele.

Outros medicamentos para a Pitiríase rósea

Outros medicamentos que podem ser tentados incluem aciclovir que é um medicamento antiviral que pode ser usado para infecções de herpes. Existe evidência limitada que Aciclovir é útil na Pitiríase rósea e além disso é benéfico somente se for tomado durante a primeira semana da doença.

Aqueles que desenvolvem infecções bacterianas secundárias sobre as lesões também necessitam de antibióticos para tratar as infecções.

Prevenção de fatores que pioram a condição

Os pacientes são aconselhados a evitar qualquer coisa que agrava a sua condição. Isso inclui banhos quentes, atividade física que leva a sudorese etc.

    MY PITYRIASIS ROSEA STORY!!!!

    So most of the stories I've read in these forums are usually vague and don't really give people the answers and hope they need. Let me tell you my "PITY" story in hopes that it will lift your spirits and help you through this....
    AHEm..this is the story of my pityriasis rosea outbreak and healing...lol

    I am 25 years old and african american
    So one day I was driving and my friend looked at my arm and said i was breaking out. I looked at ny arm and say a couple of bumps, i simply thought they were heat bumps and brushed them off.. later that day i went home and not thinking i looked at my arm and saw it was covered in many many small bumps...i have no allergies and have never had a reaction to anything. The bumps were not itchy at all and i live in florida and I'm constantly in the sun so again i thought it was a simple heat rash, so i tried to stay inside out of the sun. The next morning I woke up and not only were there more bumps, I saw they had spread to my other arm, This is the point when I started to panic, I began to think about all the things iI had done and the only different thing i could think of was the fact I had eaten peanuts from a spanish women the day before so I thought I may have been allergic or something, But hell I've eaten peanuts all my life so I know that wasn't the issue. So like every one else I took it to the web, I ruled out any STD'd because I practice safe sex, and I haven't been active for a month (BY CHOICE lol)
    I couldn't find anything that matched my symptoms....days went by and the bumps now covered my chest, my back, my neck, shoulders, and neck, eventually they would cover my face. By this point it had been 4 days, and these tiny bumps covered my body except my hands and my feet. Day 5 I happened to get in a car accident and found myself in a hospital, the nurses took off my shirt and were confused and amazed by the rash that covered my body, the doctor asked me a few questions and explained to me that I had something called Pityriasis Rosea, I WAS RELIEVED TO FIND OUT THIS MAN KNEW WHAT THIS WAS!....until he told me there was no cure, and I thought I would catch a heart attack, WHERE DID IT COME FROM?!? was my first question, but then he tells me HES not sure of the cause...No Cause...No cure....you could imagine what I was thinking. He simply smiled and said I had absolutely nothing to worry about as it would go away In a few weeks. Now Im a good looking young man...and when he told me I would look like this for weeks i almost threw my phone away as my social life had died.
           A week had gone by and these bumps had now become Raised Skin colored Patches all over, Whe  i took my clothes off, I SAW THE CHRISTMAS TREE PATTERN all over my chest and back, by this point it started to Itch like CRAZY..THIS WAS THE WORST ITCH IMAGINABLE, It was one time were every point on my body itched at the same time and I could only choose to scratch two places...I wanted to cry. I went to the store and got some **YES TO COCONUT WIPES**, **BENEDRYL**,**HEMP LOTION**,**ORGANIC MINT BODY WASH**. I immediately took a shower and used the MINYT BODY WASH, and immediately felt relief, It was as if a cool feeling covered my body, I got out of the shower, and took some benedryl, for the first time i was able to relax. It wasn't until night time that again I had an itching episode, I used the coconut wipes, and again I was relieved..I was amazed the coconut wipes worked so well, I grabbed them randomly looking for moisturisers but yet these worked better than anything else. Morning I put on the Hemp lotion with seemed to keep the patches calm, and whenever i started itching i used the coconut wipes..I found relief using these for the next few days..

    days later all the patches seemed to get flat and now my skin looked very...scaly? and dry? if that made since. I didn't care...I was just glad the bumps were gone, but now I had this to deal with..Ithe patches seemed to get flaky and just rub off. So i thought i had begun healing...unitl the itching started again..The coconut wipes didn't seem to work on this phase but the hemp seemed to keep my skin moist whenever I was drying out.
       I was now 2 weeks into the rash and now my skin seemed to get dry and flaky where ever the bumps were...I was shedding everywhere...and itching. My friend told me about how his mom used to get flaky skin when she was doing cancer treatments. So i talked to her and she told me she used **Cocobutter Petroleum Jelly** **Jergens Shea Butter Deep conditioning moisturisers** **Lotion with Aloe extract** and **aquaphor healing ointment** and i was to apply the all in that order. I put them on and for the first time since I had this god forsaken rash...My skin Felt Normal, I could see that where my skin was peeling there was light patches, It was like the darker layer of my skin was peeling off revealing a new lighter layer. Days went by and the itch became less, but I was flaking more and more, my skin looked rough and even when i scratched my head flakes began falling out, I then went and got **HEAD AND SHOULDERS SHAMPOO AND CONDITIONER**, after about 3 times the flakes on my hair began to stop. I said hell why not, I used the head and shoulders shampoo and conditioner as body wash. After about three showers, and the application of the lotions, my skin began to look like its original texture, but i still had the light patches everywhere. at first I was scared to go back out in the sun because i thought thats what started this whole mess. But my skin tone began to even out the more time i spent in the sun. The itching became less and less, AND ONLY ITCHED IF I THOUGHT ABOUT IT.
       3 Weeks in the flakes were now non existant, you could barely notice the light patches, the first part to completely clear up was my face, and I COULDN'T stop smiling. Although my skin would get dry from time to time. I was still showering with the head and shoulders and applying all four lotions. The next week all the light spots were gone, I wasn't flaking but my skin was only getting a little dry but It was completely back to the way it was before this rash started.
