EDITORIAL ESPAÑOL 
===================
Hola amigos de la red DERMAGIC EXPRESS hoy te voy a poner una actualización del VIRUS DEL PAPILOMA HUMANO, VPH.
 
Hecho que inicie hace mas de 20 años con una publicación que salio a la red en el año 1999, con el nombre de EL VPH Y SU COMPORTAMIENTO EN NUESTRO MUNDO, donde hable del comportamiento de este virus en 43 países y estaba lejos la aparición de las VACUNAS contra el mismo.
 
En el año 2017 al 2023 hice una actualización y hoy 2025 te traigo dos versiones actualizadas del VIRUS DEL VPH, esta que estas leyendo y el enlace que te dejo mas abajo de este texto publicado con el nombre de ACTUALIZACIÓN DEL VIRUS DEL PAPILOMA HUMANO (2025).
 


1.) HISTORIA DEL VIRUS DEL VPH:
 
El primero en describir el virus del VPH fue el virologo y patologo Estadounidense Richard Shope en el año 1933, lo cual hizo en verrugas cutáneas de conejos. 

Posteriormente en el año de 1974,  el medico y virologo Aleman Harald zur Hausen fue el primero en proponer que el virus del VPH podría estar vinculado o relacionado con cancer cervical en humanos, lo cual fue cierto y le valió para ganar el Premio Nobel de Medicina en el año 2008. 

A partir de la década de los 80 y años siguientes, se investigo los distintos tipos de VPH, aislándolos y clasificándolos, siendo los primeros, los VPH1, 
VPH6, VPH11, VPH16 y VPH18,  este ultimo asociado a cancer cervical. 

2.) CARACTERÍSTICAS DEL VIRUS: 
 
 El virus del PAPILOMA HUMANO, VPH es un virus ADN de doble cadena, perteneciente a la familia Papillomaviridae.
 
Se caracteriza por ser un virus de tamaño pequeño y especifico de los humanos, el cual provoca multiples infecciones en la piel y mucosas, incluyendo verrugas y neoplasias intraepiteliales en el cuello uterino de las mujeres, muchas de las cuales evolucionan a cancer. 
 
3.) IMPORTANCIA: 
 
la Importancia de este virus esta dada por tres hechos:

A.- Es el virus de transmisión sexual más común en el mundo.

B.- Cerca del 80% de las personas sexualmente activas lo contraerán alguna vez.
 
C.-  Algunos Genotipos de VPH, como lo son el VPH16 y el VPH18 y otros mas, son altamente oncogénicos (cancerígenos), a los cuales se les atribuye la mayoría de los cánceres cervicouterinos.     
 
 
4.) CLASIFICACIÓN: (AÑO 2017-2023)
 
Para el año 2.023 hay aproximadamente 200 tipos de VPH, de los cuales 51 especies afectan la mucosa genital estando clasificados así:

A.) Mas carcinogénicos los tipos: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 73, y 82. 

B.) Probable alto riesgo: el 26, 53,y 66.

C.) Bajo riesgo cancerígeno: 6, 11, 40, 42, 43, 44, 54, 61, 70, 72, 73, 81, y 108.

5.) CLASIFICACIÓN ACTUAL (AÑO 2025):
 
 En el año 2012 la Asociación Internacional para la Investigación del cancer decide modificar esta clasificación, y hoy dia se consideran solo dos (2) tipos: los de ALTO RIESGO y los DE BAJO RIESGO, en este enlace encentras la actualización del VIRUS DEL VPH, PAPILOMA HUMANO, ACTUALIZACIÓN (2025) con mas información y Referencias bibliográficas.  

A.- ALTO RIESGO: El VPH16 y VPH18 siguen siendo los más comunes en cuanto a malignidad  representando entre el 70 - 75%  de los casos de cáncer cervicouterino a nivel mundial; otros sitios de localización son: ano, vulva, vagina, pene y orofaringe.

B.-Entre el 15 al 20% adicional de casos de malignidad están representados por los genotipos de ALTO RIESGO: VPH31, 33, 45, 52 y 58, que en conjunto contribuyen a un 15-20% adicional de los casos. 
 
C.- Los otros Genotipos  que destacan por ser del ALTO RIESGO, con un 5% de los casos son: VPH35, 59, 39, 56, 51, 68, 73, 26, 69 y 82, con algunas variaciones regionales, tal es el caso de áfrica donde prevalece el VPH35. 

D.- En cuanto a los Genotipos de BAJO RIESGO, los VPH6 y VPH11 son los mas frecuentemente reportados en la papilomatosis respiratoria recurrente y y en las verrugas anogenitales, NO ASOCIADOS A CANCER.
 
 Se decidió incluir a los subtipos de MODERADO RIESGO en el grupo de los de ALTO RIESGO, basados los científicos, en el hecho de que estos finalmente iban a evolucionar a MALIGNIDAD.
 
Todo esto que estas leyendo codujo a los laboratorios a buscar y crear VACUNAS para proteger a la población mundial de la proliferación de este VIRUS, adquirido 99,9% por transmisión sexual.
 
6.) HISTORIA de la creación de las VACUNAS: 
 
A.- En la década de 1980 comenzó la investigación para la creación de una vacuna, tras descubrirse la relación existente entre el virus del VPH con el cáncer cervical.
 
B.- En 1991, Ian Fraser y Jian Zhou (Universidad de Queensland, Australia) lograron desarrollar una tecnología para crear partículas similares al virus (VLPs), elemento fundamental para la posible creación de una VACUNA.
 
Estas partículas (VLPs) fueron creadas mediante ingeniería genética con la finalidad de estimular el sistema inmune, sin contenido de material genético viral infeccioso.

 C.- En 2006 la primera vacuna fue aprobada en Estados Unidos, por los laboratorios: 
Merck & Co, (EE.UU.), MSD en Europa y Sanofi-Pasteur, con el nombre comercial de GARDASIL (tetravalente), la cual protege contra los VPH6, VPH11, VPH16, y VPH18   para cáncer cervical,  y VPH6 y VPH11 para verrugas genitales.

D.- En el año 2007 fua aprobada por la FDA la VACUNA CERVARIX (bivalente) del laboratorio 
GlaxoSmithKline (GSK, Reino Unido), la cual protege contra los virus VPH16, y VPH18, para evitar fundamentalmente el cáncer cervical, con una cobertura de aproximadamente del 66%, y a la cual también se la atribuye "ALGO" de protección cruzada contra otros tipos de alto riesgo.
 
E.) En el año 2014-2015 fua aprobada la VACUNA GARDASIL-9, (nonavalente), una version mas amplia de la clásica  GARDASIL con protección contra los virus: VPH6, VPH11, VPH16, VPH18, VPH31, VPH33, VPH45, VPH52, VPH58, es decir con una mayor cobertura (90%), contra los tipos de VPH de ALTO RIESGO de cáncer cervical y verrugas.
 
 
 Los efectos adversos, los cuales suelen ser transitorios y autolimitados, más frecuentes son:
 
A.- Locales y leves:
 
- Dolor.
- Eritema (enrojecimiento) e hinchazón en el sitio de la inyección. 
- Cefalea.
- Mareos. 
 
B .- Moderados a graves: 
 
- Sincope y desmayos: especialmente en adolescentes, por lo que se recomienda observar al  paciente, por lo menos 15 minutos luego de la administración, con el objetivo de prevenir lesiones secundarias, en caso de desmayos.
 
- Pueden ocurrir reacciones anafilacticas graves cuando hay alergia comprobada a los componentes de la vacuna, y son extremadamente raras. 
 
 - La incidencia de Sincope y reacciones locales se ha descrito con mayor frecuencia en la GARDASIL-9 (nonavalente), en comparación con la clásica GARDASIL (tetravalente).
 
-  Hay ABSOLUTA contraindicacion , cuando se ha comprobado que el paciente ha experimentado reacciones severas, a la administración de otras vacunas. 
 
C.- Eventos adversos posteriores a la vacuna contra el virus del papiloma humano 9-valente (GARDASIL® 9) notificados al Sistema de Notificación de Eventos Adversos de Vacunas (VAERS), 2015-2024:
 
Eventos no mencionados en la ETIQUETA del producto:
 
 
Hubo ademas 57 informes de defunción (MUERTE), de los cuales 18 fueron en mujeres embarazadas, pero los términos o características neurológicas carecían de patrones etológicos contundentes, de modo que el sistema VAERS, concluye que dicha vacuna es "segura".
 
Pero si quieres indagar mas a fondo de lo que ha sucedido con estas vacunas aquí te dejo el enlace de la publicación EL SÍNDROME POST VACUNACIÓN GARDASIL Y CERVARIX (2017), el cual "muestra" una cara totalmente a el sistema VAERS del año 2015 al 2024.

 8.) CONCLUSIÓN:
"En un periodo de 23 a 25 años aparecieron unas 120 CEPAS nuevas DEL VIRUS PAPILOMA HUMANO V.P.H, quizá este aumento cabalgante fue lo que llevo a los laboratorios a FABRICAR VACUNAS para esta enfermedad, la experiencia con las mismas ha sido CONTROVERSIAL", pero el hecho de que protejan contra los dos tipos de VPH mas oncogenicos es un "SIGNO POSITIVO."

En este enlace encuentras la publicación ORIGINAL del VIRUS DEL VPH Y SU COMPORTAMIENTO EN EL MUNDO (1999); es importante que te la leas, para que aprendas como ha evolucionado el comportamiento de este virus en la población mundial desde ese año hasta nuestros días. 

NOTA: Actualmente estas vacunas tienen un costo de 250$ dolares Americanos en Venezuela. 

Saludos a todos!!!

EDITORIAL ENGLISH
=================
Hello friends of the DERMAGIC EXPRESS network, today I'm going to give you an UPDATE ON THE HUMAN PAPILLOMAVIRUS (HPV).

This article began more than 20 years ago with a publication published online in 1999, entitled "HPV AND ITS BEHAVIOR IN OUR WORLD." I discussed the behavior of this virus in 43 countries, and the emergence of vaccines against it was still far from complete.

From 2017 to 2023, I updated it, and today, in 2025, I'm bringing you two updated versions of the HPV virus: the one you're reading and the link at the end of this article, published under the name HUMAN PAPILLOMA VIRUS (HPV) UPDATE (2025)."

1.) HISTORY OF THE HPV VIRUS:


The first to describe the HPV virus was the American virologist and pathologist Richard Shope in 1933, which he did in rabbit skin warts.

Later, in 1974, the German physician and virologist Harald zur Hausen was the first to propose that the HPV virus could be linked or related to cervical cancer in humans, which proved true and earned him the Nobel Prize in Medicine in 2008.

Beginning in the 1980s and following years, the different types of HPV were investigated, isolated, and classified. The first were HPV1, HPV6, HPV11, HPV16, and HPV18, the latter being associated with cervical cancer.

2.) CHARACTERISTICS OF THE VIRUS:


The human papillomavirus (HPV) is a double-stranded DNA virus belonging to the Papillomaviridae family.

It is characterized by being a small, human-specific virus that causes multiple skin and mucous membrane infections, including warts and cervical intraepithelial neoplasia in women, many of which progress to cancer.

3.) IMPORTANCE:
The importance of this virus is based on three facts:

A. It is the most common sexually transmitted virus in the world.

B. About 80% of sexually active people will contract it at some point.

C.- Some HPV genotypes, such as HPV16 and HPV18, among others, are highly oncogenic (carcinogenic), and are responsible for the majority of cervical cancers.

4.) CLASSIFICATION: (YEAR 2017-2023):

As of 2023, there are approximately 200 types of HPV, of which 51 species affect the genital mucosa. They are classified as follows:

A.)Most carcinogenic types: 
 HPV16, HPV18, HPV31, HPV33, HPV35, HPV39, HPV45, HPV51, HPV52, 
 HPV56, HPV58, HPV59, HPV68, HPV73, and HPV82.

B.) Probable high risk: 
HPV26, HPV53, and HPV66.

C.) Low carcinogenic risk: 
 HPV6, HPV11, HPV40, HPV42, HPV43,HPV HPV44,
 HPV54, HPV61, HPV70, HPV72, HPV73, HPV81, and HPV108.

5.) CURRENT CLASSIFICATION (YEAR 2025):

In 2012, the International Association for Cancer Research decided to modify this classification, and today only two (2) types are considered: HIGH RISK and LOW RISK. At this link, you will find the update on the HPV, HUMAN PAPILLOMA VIRUS, UPDATE (2025). 
with more information and bibliographic references.

A.- HIGH RISK: HPV16 and HPV18 continue to be the most common types of malignancy, representing between 70-75% of cervical cancer cases worldwide. Other sites include: anus, vulva, vagina, penis, and oropharynx.

B. Between 15 and 20% of additional malignancy cases are represented by the HIGH-RISK genotypes: HPV31, 
HPV33, HPV45, HPV52, and HPV58, which together contribute to an additional 15-20% of cases.

C. The other genotypes that stand out as HIGH-RISK, accounting for 5% of cases, are: HPV35, 
HPV59, HPV39, HPV56, HPV51, HPV68, HPV73, HPV26, 
HPV69, and HPV82, with some regional variations, such as in Africa, where HPV35 is prevalent.

D.- Regarding the LOW-RISK genotypes, HPV6 and HPV11 are the most frequently reported in recurrent respiratory papillomatosis and anogenital warts, NOT ASSOCIATED WITH CANCER.

It was decided to include the MODERATE RISK subtypes in the HIGH RISK group, based on the scientists' assumption that these would eventually evolve into MALIGNANCY.

All of this you are reading led laboratories to search for and create VACCINES to protect the world's population from the spread of this VIRUS, 99.9% of which is acquired through sexual transmission.

6.) HISTORY OF THE CREATION OF VACCINES:

A.- In the 1980s, research into the creation of a vaccine began after the link between the HPV virus and cervical cancer was discovered.

B.- In 1991, Ian Fraser and Jian Zhou (University of Queensland, Australia) developed a technology to create virus-like particles (VLPs), a fundamental element for the possible creation of a VACCINE.

These particles (VLPs) were created through genetic engineering with the aim of stimulating the immune system, without containing infectious viral genetic material.

C.- In 2006, the first vaccine was approved in the United States by the laboratories: Merck & Co. (USA), MSD in Europe, and Sanofi-Pasteur, under the brand name GARDASIL (tetravalent). It protects against HPV6, HPV11, HPV16, and HPV18 for cervical cancer, and HPV6 and HPV11 for genital warts.

D.- In 2007, the FDA approved the CERVARIX (bivalent) vaccine from GlaxoSmithKline (GSK, United Kingdom). It protects against the HPV16 and HPV18 viruses, primarily to prevent cervical cancer, with a coverage of approximately 66%. It is also attributed with "SOME" cross-protection against other high-risk types.

E.) In 2014-2015, the GARDASIL-9 VACCINE (nine-valent) was approved. This is a broader version of the classic GARDASIL vaccine, offering protection against the following viruses: HPV6, HPV11, HPV16, HPV18, HPV31, HPV33, HPV45, HPV52, and HPV58. This vaccine offers greater coverage (90%) against high-risk HPV types for cervical cancer and warts.

7.) SIDE EFFECTS OF THE VACCINES:

The most common adverse effects, which are usually transient and self-limiting, are:

A.- Local and mild:

- Pain.
- Erythema (redness) and swelling at the injection site.
- Headache.
- Dizziness.

B. Moderate to severe:


- Syncope and fainting: especially in adolescents, so it is recommended that the patient be observed for at least 15 minutes after administration to prevent secondary injuries in the event of fainting.

- Severe anaphylactic reactions can occur when there is a known allergy to vaccine components and are extremely rare.

- The incidence of syncope and local reactions has been reported more frequently with GARDASIL-9 (nine-valent) compared to the classic GARDASIL (four-valent).

- There is an ABSOLUTE contraindication to the administration of other vaccines when the patient has been known to experience severe reactions.

C. Adverse events following the 9-valent human papillomavirus vaccine (GARDASIL® 9) reported to the Vaccine Adverse Event Reporting System (VAERS), 2015-2024:

Events not listed on the product label:

- Postural orthostatic tachycardia syndrome.
- Eye movement disorders.
- Autoimmune thyroiditis.
- Postural abnormality.

There were also 57 reports of deaths, 18 of which were in pregnant women, but the neurological characteristics or features lacked compelling etiological patterns, so the VAERS system concludes that the vaccine is "safe."

But if you want to delve deeper into what has happened with these vaccines, here is the link to the publication "POST-VACCINATION SYNDROME WITH GARDASIL AND CERVARIX" (2017), which completely "shows" the other "face" of the VAERS system from 2015 to 2024.

8.) CONCLUSION:
"Over a period of 23 to 25 years, some 120 new STRAINS OF THE HUMAN PAPILLOMAVIRUS (HPV) appeared. Perhaps this dramatic increase was what led laboratories to manufacture vaccines for this disease. Experience with these vaccines has been CONTROVERSIAL," but the fact that they protect against the two most oncogenic HPV types is a "POSITIVE SIGN."
At this link, you'll find the original publication "HPV VIRUS AND ITS BEHAVIOR IN THE WORLD" (1999). It's important to read it to learn how the behavior of this virus has evolved in the global population from that year to the present.

NOTE: These vaccines currently cost $250 in Venezuela.

Greetings to all!!!

EDITORIAL ENGLISH
===================
Hola amigos de la red, EL DERMAGIC EXPRESS hoy les trae un tema bien interesante: HERPES ZOSTER, NEURALGIA Y VACUNAS. 
 
El HERPES ZOSTER, es una enfermedad viral producida por el virus de la VARICELA-ZOSTER. La enfermedad se presenta por una reactivación del virus de la VARICELA que queda latente en los ganglios nerviosos de nuestro organismo y puede aparecer muchos años después del primer evento (VARICELA).

El HERPES ZOSTER es conocido en America latina bajo el nombre popular de "CULEBRILLA", en idioma ingles como "SHINGLES", y en algunos países de Europa como "FUEGO DE SAN ANTONIO".

La enfermedad se presenta como un trayecto vesiculoso ampollar serpiginoso en la piel que sigue una metamera nerviosa o dermatoma (nervio raquídeo), y su ganglio espinal). 
 
La duración varia entre 15 y 21 días y su principal complicación es la NEURALGIA POST-HERPETICA (NPH), que consiste en una sensación dolorosa crónica en el area afectada (dermatoma), que puede durar desde varias semanas hasta años, con un promedio entre 3 y 6 meses.
 
 La distribución de la enfermedad es mundial y las personas mas afectadas son las de mayor edad.

Otras complicaciones incluyen INFARTO AL MIOCARDIO (CORAZÓN) , INFECCIÓN SECUNDARIA, daño ocular (ZOSTER OFTÁLMICO, y otras complicaciones neurológicas (NEURALGIAS CRÓNICAS Y PARESTESIAS).

La incidencia estimada en Europa oscila entre 2,0 y 4,6 casos por 1.000 habitantes, con un fuerte aumento en sujetos de más de 50 años de edad.

También se ha descrito una asociación GENÉTICA dada por los Antígenos de Histocompatibilidad HLA-A33 y B44, con  susceptibilidad a padecer NEURALGIA POST-HERPETICA.

La ciencia no deja de sorprendernos en su afán por derrotar las enfermedades, y el HERPES ZOSTER Y LA NEURALGIA POST - HERPETICA  representan un palpable ejemplo del avance científico en el area viral.

En el año 1.974 fue descubierto el ACICLOVIR.  El descubrimiento de esta medicina fue considerado el comienzo de una nueva era en la terapia antiviral, que dio pie a que los científicos Gertrude Belle Elion y George H. Hitchings recibieran el Premio Nobel de Medicina en 1.988, debido, en parte al desarrollo de este compuesto.

Mas tarde apareció el FAMCICLOVIR en 1.994 y posteriormente el VALACICLOVIR en 1.995. Estas drogas tienen probados efectos contra las infecciones por el virus VARICELA ZOSTER (VZV), y también herpes simple (HSV). 
 
Hay otras mas como el GANCICLOVIR, VALGANCICLOVIR, PENCICLOVIR y  BRIBUDIN.

Pero la ciencia no se detuvo allí, casi una década después, en el año 2.006 fue aprobada la primera VACUNA para prevenir el HERPES ZOSTER, para ser usada en Estados Unidos y la Union Europea, aprobada por la FDA (Food and drug administration), denominada ZOSTAVAX,  compuesta por virus atenuados Varicela Zoster, para ser utilizada en personas de 50 años o mas y evitar el HERPES ZOSTER y por ende la NEURALGIA POST-HERPETICA, o atenuar su aparición.

Posteriormente en el 2.012 es sintetizado y comercializado VARIZIG suero de inmunoglobulinas Varicela Zoster, para ser utilizado en personas que tuvieron exposición al VIRUS VARICELA ZOSTER, principalmente:

1.) NIÑOS Y ADULTOS INMUNO COMPROMETIDOS.
2.) RECIÉN NACIDOS DE MADRES CON VARICELA, POCO ANTES O DESPUÉS DEL PARTO.
3.) BEBES PREMATUROS.
4.) LACTANTES MENORES DE UN AÑO DE EDAD.
5.) ADULTOS SIN EVIDENCIA DE INMUNIDAD.
6.) MUJERES EMBARAZADAS.

En muchos países no esta comercializada la vacuna contra el HERPES ZOSTER, de modo que se puede presentar la enfermedad, con la subsecuente NEURALGIA POST-HERPETICA.

En estas referencias bibliográficas encontraras ademas de las mencionadas VACUNAS, alternativas terapéuticas para la NEURALGIA POST-HERPETICA; te menciono algunas de ellas:

1.) CAPSAICINA TOPICA.
2.) CORTICOESTEROIDES.
3.) ACICLOVIR.
4.) VALACICLOVIR.
5.) FAMCICLOVIR.
6.) BLOQUEO NEURAL.
7.) LIDOCAINA TOPICA.
8.) ANTIDEPRESIVOS TRICICLICOS: AMITRIPTILINA, NORTRIPTILINA

11.) TRAMADOL.
12.) IBUPROFENO.
13.) CODEINA.
14.) RADIOFRECUENCIA.
15.) VITAMINA C.
16.) TOXINA BOTULINICA.
17.) TALIDOMIDA.
18.) LEVODOPA.
19.) FOTOTERAPIA: LUZ ULTRAVIOLETA B
20.) TRIAMCINOLONA.
21.) BRIBUDIN.

EDITORIAL ENGLISH
==================
Hello friends of the network, THE DERMAGIC EXPRESS today brings you a very interesting topic: HERPES ZOSTER, NEURALGIA AND VACCINES.
 
HERPES ZOSTER is a viral disease caused by the VARICELLA-ZOSTER virus. The disease is caused by a reactivation of the VARICELLA virus that is latent in the nerve ganglia of our organism, and can appear many years after the first event (VARICELLA).

HERPES ZOSTER is known in Latin America under the popular name of "CULEBRILLA", in English language as "SHINGLES", and in some countries of Europe as "FIRE OF SAINT ANTONY".

The disease occurs as a serpiginous blistering vesicle pathway in the skin that follows a metameric nerve or dermatome (spinal nerve and its spinal ganglion). 
 
The duration varies from 15 to 21 days and its main complication is POSTHERPETIC NEURALGIA (PHN), which consists of a chronic painful sensation in the affected area (dermatome), which can last from several weeks to years, with an average of 3 to 6 months.
 
The distribution of the disease is worldwide and the people most affected are the oldest.

Other complications include MYOCARDIAL INFARCTION (MI), SECONDARY INFECTIONS, eye damage (OPHTHALMIC ZOSTER) and other neurological complications (CHRONIC NEURALGIAS AND PARESTHESIAS).

The estimated incidence in Europe ranges from 2.0 to 4.6 cases per 1,000 inhabitants, with a strong increase in subjects over 50 years of age.

It has also been described a GENETIC association related with the HLA-A33 and B44 Histocompatibility Antigens with susceptibility to suffer POST-HERPETIC NEURALGIA (PHN).

 Science does not cease to defend itself in its battle to defeat diseases, and HERPES ZOSTER AND POST-HERPETIC NEURALGIA, represents a palpable example of the scientific advance in the viral area.

In the year 1.974 the ACICLOVIR was discovered. The discovery of this medicine was seen as the beginning of a new era in antiviral therapy, which led scientists Gertrude Belle Elion and George H. Hitchings to receive the Nobel Prize in Medicine in 1.988 due in part to the development of this compound.

Later on FAMCICLOVIR appeared in 1.994 and later the VALACICLOVIR in 1.995. These drugs have proven effects against the infections of the virus VARICELLA ZOSTER (VZV) And also herpes simplex (HSV). There are others such as GANCICLOVIR, VALGANCICLOVIR, PENCICLOVIR and BRIBUDIN.

But science did not stop there, almost a decade later, in 2.006 the First vaccine to prevent HERPES ZOSTER,  was discovered, to be used in the United States and the European Union, approved by the FDA (Food and drug administration), ZOSTAVAX, composed of attenuated virus Varicella Zoster, to be used in people 50 years and over, to Avoid the HERPES ZOSTER and therefore the POST-HERPETIC NEURALGIA or mitigate its appearance.


Subsequently in 2.012 it is synthesized and commercialized VARIZIG, varicella-zoster immunoglobulin serum was then synthesized and marketed for use in people who had exposure to the VARICELLA ZOSTER VIRUS, mainly:

1.) IMMUNOCOMPROMISED CHILDREN AND ADULTS.
2.) NEWBORNS OF MOTHERS WITH CHICKENPOX SHORTLY BEFORE OR AFTER DELIVERY.
3.) PREMATURE BABIES..
4.) INFANTS LESS THAN ONE YEAR OF AGE.
5.) ADULTS WITHOUT EVIDENCE OF IMMUNITY.
6.) PREGNANT WOMEN.

In many countries the vaccine against HERPES ZOSTER is not commercialized, so that the disease can be present with the subsequent POST-HERPETIC NEURALGIA (PHN).

In these bibliographical references you will find in addition to the aforementioned VACCINES, therapeutical alternatives for subsequent POST-HERPETIC NEURALGIA, I mention some of them:

1.) TOPIC CAPSAICIN.
2.) CORTICOESTEROIDS.
3.) ACICLOVIR.
4.) VALACICLOVIR.
5.) FAMCICLOVIR.
6.) NEURAL BLOCKING.
7.) TOPICAL LIDOCAINE.
8.) TRICYCLIC ANTIDEPRESSANTS: AMITRIPTYLINE, NORTRIPTYLIN.
9.) GABAPENTIN.
10.) PREGABALIN.
11.) TRAMADOL.
12.) IBUPROFEN.
13.) CODEIN.
14.) RADIOFREQUENCY.
15.) VITAMIN C.
16.) BOTULINIC TOXIN.
17.) THALIDOMIDE.
18.) LEVODOPA.
19.) PHOTOTHERAPY: ULTRAVIOLET LIGHT B
20.) TRIAMCINOLONE.
21.) BRIBUDIN.


Currently in 2.017  another vaccine is being developed under the name of: HZ / SU SUBUNIT that combines a key surface glycoprotein (E) of the virus VARICELLA ZOSTER (VZV) with a T cell reinforcing agent (AS01B), To be used in both HERPES ZOSTER and POST-HERPETIC NEURALGIA (PHN).
