Psoriasis

Psoriasis is a chronic, inflammatory disease which can affect the skin, tendons, ligaments, and joints (Gottlieb, 2001; Gottlieb & Bos, 2002; Lebwohl, 2003). It has a multifactorial inheritance in which several genes interact with environmental factors to produce varying degrees of severity. Prevalence rates range from 0.5% to 4.6% depending on the country and race (Lebwohl, 2003). It more commonly affects Caucasians and patients living at higher latitudes (Lebwohl, 2003). Although it is not a life-threatening condition, it can lead to significant impairment and psychological stress. Patients who are severely afflicted can have up to 100% body surface area involvement.

There are several clinical variants of psoriasis, including plaque, guttate, erythrodermic, and pustular (Lebwohl, 2003). Plaque type is the most common form, representing 80% of cases, while guttate, erythrodermic, and pustular account for 10%, 3%, and 3% of patients respectively. Cutaneous lesions usually precede joint disease in 70% of patients with psoriasis.

Psoriatic arthritis, a seronegative arthopathy, can affect upwards of 42% of patients with psoriasis (Lebwohl, 2003). Several forms exist, including polyarticular, oligoarticular, distal interphalangeal, arthritis mutilans, spondylitis, and sacroiliitis. Like rheumatoid arthritis, psoriatic arthritis can lead to joint deformities, disability, and increased mortality.Pathogenesis

While the entire pathogenesis of psoriasis remains largely unknown, recent discoveries have been made which have elucidated the pivotal role of T cells (Lebwohl, 2003). This discovery was made through the use of severe combined immunodeficiency mouse models and further supported by the dramatic response to agents such as methotrexate, cyclosporin, and denileukin diftitox, all of which modulate T-cell activity (Gottlieb, 2001). This process begins with the presence of antigens, which cause the maturation of Langerhans cells and the migration of antigen-presenting cells (APC) to the lymph node. Once in the lymph node, the APCs interact with naEFve T cells, causing T-cell activation and subsequent T-cell proliferation. Some of these proliferating T cells are memory T cells, which ultimately migrate to the inflamed target areas of the skin. When these T cells are activated, they will release type 1 cytokines (Th1), such as interferon gamma, IL-2 and IL-12, and TNF (Gottlieb, 2001; Gottlieb & Bos, 2002). These cytokines are responsible for keratinocyte proliferation and lack of maturation, and vascular changes characteristic of psoriasis.Treatment

Three broad categories of treatment options exist for psoriasis, including topical modalities, phototherapy, and systemic therapy (Lebwohl, 2003). Topical treatments are effective for patients with mild-to-moderate psoriasis, while phototherapy and systemic medications are appropriate for more severe cases. These topicals include topical steroids, tar, anthralin, vitamin D analogues, and retinoids.

Phototherapy encompasses treatment with PUVA, broadband and narrowband UVB, and the 308 nm excimer laser (Lebwohl, 2003). Prior to beginning PUVA, laboratory tests, such as antinuclear antibodies, should be performed. This is to ensure that the patient does not harbor undiagnosed collagen vascular disease/photosensitivity. Also, since psoralen, which is ingested prior to UVA exposure, is a photosensitizer and can cause heptotoxicity, liver function tests should be obtained.

In patients afflicted with severe psoriasis, systemic therapies have been effective, but some carry significant side effects (Lebwohl, 2003). Several systemic medications can be used for psoriasis, such as methotrexate, cyclosporin, retinoids, and more recently targeted immunotherapies (biologics). Patients treated with methotrexate must be monitored for bone marrow and hepatic toxicities. Retinoids can cause mucocutaneous side effects, hair loss, nail thinning, and teratogenicity. Cyclosporin use can lead to nephrotoxicity, hypertension, or development of lymphomas with prolonged use; therefore, its use is usually limited to 1 year.

Recently targeted immunotherapies have become popular alternatives for patients with severe psoriasis. These treatments target specific cells, cytokines, or interactions to achieve remission (Lebwohl, 2003). Not only are these alternatives effective, but they have a more favorable side effect profile than the traditional systemic agents. Alefacept (Amevive®) and denileukin diftitox (Ontak®) are fusion proteins which eliminate activated T cells by targeting the interaction between LFA3 on APC and CD2 on T cells, and by binding to IL2 receptor (CD25) to release diphtheria toxin, respectively. Inhibition of T-cell activation/proliferation has been achieved with several therapies, including a monoclonal antibody to anti-CD4, anti-CD80, anti-CD25 (daclizumab), anti-CD11a (efalizumab), and anti-CD2 (siplizumab). Also, CTLA4Ig is a fusion protein which binds to CD80 and CD86 on APCs to inhibit T-cell activation. Immune deviation has been achieved through the use of IL4 and 10, which are type 2 cytokines (Th2) that counteract the Th1 predominance found in psoriasis. Finally, inhibition of cytokines is accomplished with infliximab (Remi cade®), a chimeric mouse-human monoclonal antibody which inhibits TNFα (see Figures 1 & 2); etanercept (Enbrel®), a fusion protein which inhibits TNFα (see Figures 3-6); adalimumab (Humira®), a fully humanized monoclonal antibody to TNFα; and anti-IL8.

Infliximab (Remicade®)

Infliximab is a chimeric monoclonal IgG antibody which inhibits TNFα activity and triggers complement mediated lysis of TNFα expressing cells in vitro (Gottlieb, 2001; Gottlieb & Bos, 2002; LaDuca & Gaspari, 2001; Lebwohl, 2003; Victor & Gottlieb, 2002; Williams & Griffiths, 2002). It is made from human constant and mouse variable regions of IgG. It neutralizes soluble and blocks membrane-bound TNFα. It is FDA approved for the treatment of Crohn's disease and rheumatoid arthritis (RA) at intravenous doses of 5 mg/kd and 3 mg/kg respectively. The infusion is given over at least 2 hours and has a half life of 8 to 10 days (Williams & Griffiths, 2002). Crohn's disease without fistulas is treated with one dose of infliximab at 5 mg/kg, while the presence of fistulas requires three doses of 5 mg/kg at weeks 0, 2, and 6. RA is treated with 3 mg/kg at weeks 0, 2, 8, and every 8 weeks thereafter.

It was discovered that infliximab was effective in treating psoriasis after a patient with recalcitrant Crohn's and psoriasis was treated with infliximab for her Crohn's (LaDuca & Gaspari, 2001; Victor & Gottlieb, 2002). After the infusion, not only did her Crohn's improve, but also her psoriasis. In a randomized double blind placebo controlled trial, 33 patients were randomized to a placebo arm, a 5 mg/kg arm, or a 10 mg/kg arm and treated on weeks 0, 2, 6 (Chaudhari et al., 2001). Eighty-two percent of patients in the 5 mg/kg arm, 91% of patients in the 10 mg/kg arm, and 18% of patients in the placebo arm achieved a greater than 75% improvement on Psoriasis Index and Severity Score (PASI) after 10 weeks. Treatment began working within 2 weeks and sustained this improvement for more than 6 months. Immunohistochemical staining showed decreased epidermal inflammation and normalization of keratinocyte differentiation. No serious adverse effects were noted.

Phase II open label data showed that 55% of patients with psoriasis treated with infliximab retained a 50% or greater reduction in the original PASI scores after 26 weeks, with no further infusions (Gottlieb, Chaudhari, Mulcahy, Dooley, & Baker, 2003).

Infliximab was also successful in the treatment of pustular psoriasis, a severe, debilitating, and recalcitrant variant of psoriasis. Elewski (2002) treated two patients with infliximab 5mg/kg on weeks 0, 2, and 6. The patients tolerated the infusion well without any side effects. Clearance began within the first few days after the first infusion with continued improvement until complete clearance. This complete clearance was maintained for 10 weeks after the last infusion. Newland, Weinstein, and Kerdel (2002) reported one case of pustular psoriasis treated successfully with one infusion of infliximab 5 mg/kg. Complete resolution of the pustules occurred by day 4. The infusion was well tolerated without any side effects.

In a 6-month trial, 12 patients with recalcitrant psoriatic arthritis were treated with infliximab 5 mg/kg on weeks 0, 2, 6, 14, 22 along with their previous treatments of steroids and methotrexate (Provenzano, Termini, Le Moli, & Rinaldi, 2003). No infusion reactions were noted. Two patients were withdrawn from the study, one for angina pectoris and one for pulmonary malignancy, which were not considered a result of the infliximab infusions. Significant improvement was noted in all patients.

An open label pilot study was conducted with 21 patients with recalcitrant spondyloarthropathy, 9 of which had psoriatic arthritis (Van Den Bosch et al., 2000). They were treated with infliximab 5 mg/kg at weeks 0, 2, 6, along with methotrexate. Rapid and significant improvement was noted in all patients without any significant side effects. PASI scores showed significant improvement at day 14 compared to baseline, and this improvement was sustained at day 84. Global and peripheral assessment of psoriatic arthritis showed significant improvement in all areas at day 14 compared to baseline, and this significant improvement was maintained at day 84.

Drawbacks are few and include headache, diarrhea, rash, pharyngitis, rhinitis, cough, upper respiratory infection, and urinary tract infection (LaDuca & Gaspari, 2001; Lebwohl, 2003; Mease, 2002; Provenzano et al., 2003; Van Den Bosch et al., 2000; Williams & Griffiths, 2002). Rare instances of more severe side effects have occurred, such as reactivation of pulmonary tuberculosis, aseptic meningitis, sepsis, and development of anti-dsDNA and systemic lupus. Keane et al. (2001) reported 70 cases of TB developing after the use of infliximab, 40 of which had extrapulmonary disease. The incidence of TB with infliximab is much higher than with etanercept. This reactivation of TB has been attributed to immune system disruption, manifested as the failure of granulomas to compartmentalize the bacilli, and inhibition of macrophage apoptosis after the use of infliximab. Patients are required by the Food and Drug Administration to have a negative purified protein derivative (PPD) test and negative chest radiograph prior to starting infliximab therapy. There is also concern of long-term development of antibodies to the drug. In patients with Crohn's treated with repeated infusions of infliximab, 13% developed antibodies against the medication (Tan, Gordon, Lebwohl, George, & Lebwohl, 2001). The presence of these antibodies has lead to the loss of clinical efficacy, the development of infusion reactions, chest pain, bronchospasm, and anaphylactic shock. The rate of antibody formation is inversely related to dose and decreases with the addition of low-dose methotrexate (Lebwohl, 2003). How this will translate in patients with psoriasis remains to be seen. Infusion reactions, such as anaphylaxis and bronchospasm, can occur rarely, and can be treated by slowing the infusion rate and pretreating with antihistamines or steroids. Relative contraindications to the use of infliximab include congestive heart failure, demyelinating disorders, lupus, lymphoma/malignancy, antibody formation to infliximab, hypersensitivity to murine products, and sepsis. Infliximab is a pregnancy class B drug.Etanercept (Enbrel®)

Etanercept is a recombinant human TNFα receptor fusion protein, which consists of the extracellular domains of two TNFα receptor p75 receptors and the constant (Fc) region of IgG1, which inhibits soluble TNFα. In contrast to infliximab, etanercept binds to and inhibits only soluble TNFα (Gottlieb, 2001; Gottlieb & Bos, 2002; LaDuca & Gaspari, 2001; Lebwohl, 2003; Victor & Gottlieb, 2003; Williams & Griffiths, 2002). It is FDA approved for the treatment of adult rheumatoid (RA) and psoriatic arthritis (PA) at doses of 25 mg twice a week administered subcutaneously.

It was noted that in the treatment of patients with PA, their psoriasis improved as well (Davison, Bunker, & Basarab, 2002; Galadari, Fuchs, & Lebwohl, 2003; Iyer, Yamauchi, & Lowe, 2002; Kurschat et al., 2001). Mease et al. (2002a) enrolled 60 recalcitrant psoriatic arthritis patients in a double-blind placebo-controlled study comparing subcutaneous injections of etanercept 25 mg twice a week to placebo. Patients continued on metho trexate. After 12 weeks, 87% of etanercept-treated patients versus 23% of placebo-treated patients responded significantly based on the Psoriatic Arthritis Response Criteria (PsRC). Using the American College of Rheumatology criteria (ACR20), statistically significant improvement was noted in 73% of the etanercept-treated patients and 13% of the placebo-treated patients at 12 weeks. Also, 26% of the etanercept-treated patients had a 75% improvement in PASI scores, while none of the placebo patients improved. Only 20 of the patients reported side effects, namely injection site reactions, but no significant side effects were noted. After 4 months of followup, five patients had no joint pain and 55 had only mild symptoms. In the phase III trial of etanercept for PA, there was a median improvement in PASI in 33% in the etanercept group and none in the placebo groups (Mease et al., 2000a).

In a subsequent 12-week double-blind placebo-controlled study of etanercept for psoriasis, 70% of patients given etanercept had improvement in their PASI scores (Gottleib, Matheson, Lowe, & Zitnik, 2002). Fifty-six percent of patients treated with etanercept and 5% of placebo-treated patients had a 75% reduction in PASI scores at 24 weeks.

The most common side effect was injection site reactions (Gottleib et al., 2002; Mease et al., 2000a; Mease, Goffe, & Betz, 2000b). Other uncommon side effects were upper-respiratory infections, headache, rhinitis, abdominal pain, vomiting, pharyngitis, nausea, gastrointestinal infection, and rash. Antibody formation is less likely to occur in etanercept-treated patients compared to infliximab (Lebwohl, 2003). Thirteen cases of TB reactivation have been reported (Goffe & Cather, 2003; Keane et al., 2001). Unlike infliximab, etanercept-associated TB occurs sporadically and later in the course of treatment. Even though the FDA does not require a negative chest radiograph and PPD, both should be performed. More serious reactions have occurred, including demyelinating disorders, aplastic anemia, allergic reactions, and development of positive ANA, anti-dsDNA, and drug-induced systemic lupus. No malignancies have been discovered during the FDA trials; however, Smith and Skelton (2001) reported seven cases of squamous cell carcinoma occurring in patients with RA treated with etanercept (Smith & Skelton, 2001). It has been found in long-term RA studies using etanercept that the incidence of malignancy was not increased over age-matched controls (Goffe & Cather, 2003). Relative contraindications to use of etanercept include sepsis, malignancy, congestive heart failure, and demyelinating diseases. It is a pregnancy class B drug.  Printer- Friendly Email This

Case Report

A 38-year-old Hispanic man with no significant medical history came to the emergency room with complaints of a "10/10" retroorbital headache, photophobia, fevers, and a rash. The patient reported that he was in his usual state of good health until 2 weeks before admission, when he was placed on a 14-day course of TMP-SMZ (Bactrim DS), loratadine (Claritin), and acetaminophen for symptoms of cough, rhinorrhea, and sinus congestion. Despite treatment, symptoms continued. Myalgias, intermittent chills, and subjective fevers developed 1 week before admission. Two days before admission, a diffuse "red rash" and conjunctivitis developed. Treatment with sulfacetamide ophthalmic solution was started the evening before admission. Eye pain intensified after administration of the ophthalmic solution, and the patient had a headache that prompted the emergency room visit.

The patient denied nausea, vomiting, diarrhea, or weight loss. He denied any recent travel, unusual food, or animal exposure and reported that one coworker was ill with pneumonia. He reported being heterosexual and appropriately using a condom during his last sexual encounter 7 months earlier. He denied history of blood transfusion; use of tobacco, alcohol, or intravenous drugs; or homosexual activity. There was no history of medication allergies or previous exposure to TMP-SMZ.

On examination, the patient appeared thin, ill, and in moderate distress. Vital signs were blood pressure 95/54 mm Hg, heart rate 118/min, respiratory rate 22/min, and temperature 101.7°F. Physical examination was notable for nonicteric sclera, marked bilateral conjunctival injection, photophobia, shoddy cervical adenopathy, and lack of meningeal signs. The oropharynx was erythematous without exudate, lesions, or ulcers. Cardiac and lung examinations were normal. There was a diffuse, nonblanching, erythematous, macular eruption over the torso with no evidence of target lesions. There was 1+ pretibial, pitting edema bilaterally. Laboratory values were white blood cell count of 5.1 x 109/L (53% segmented neutrophils, 39% band forms, 7% lymphocytes, and 1% monocytes), hemoglobin 149 g/L, hematocrit 43.7%, and platelets 249 x 109/L. Liver-associated enzyme levels were elevated, with alkaline phosphatase 131 U/L (normal, 38 to 126 U/L), aspartate aminotransferase 103 U/L (normal, 14 to 36 U/L), alanine aminotransferase 111 U/L (9 to 52 U/L), and total bilirubin 8.55 mmol/L. Lumbar puncture revealed clear, colorless fluid with negative Gram's stain, white blood cell count 22 x 109/L (97% lymphocytes, 2% segmented neutrophils, 1% monocytes), protein 0.74 g/L, and glucose 2.66 mmol/L. Serum glucose was 5.66 mmol/L. Electrolytes, prothrombin time, partial thromboplastin time, and urinalysis were normal. Computed tomography of the sinuses and a chest radiograph were unremarkable.

The patient was admitted to the hospital, sulfa-containing medications were discontinued, and intravenous (IV) piperacillin sodium-tazobactam sodium (Zosyn) and IV erythromycin were started, given the clinical picture consistent with sepsis. The infectious diseases and dermatology services were both consulted, and the patient's symptoms were thought to be consistent with those of a hypersensitivity reaction to sulfa drugs. During hospital day 1, he continued to have fevers up to 103°F, with persistent rash, myalgias, and headache. On the second hospital day, a capillary leak syndrome developed, manifested by pulmonary edema, a mild coagulopathy without bleeding, and peripheral edema. Oxygen and supportive measures were used. On hospital day 3, he was afebrile without headache, and the rash was resolving. All blood, urine, and cerebrospinal fluid cultures done on admission remained negative for organisms, and antibiotics were discontinued. He was monitored without recurrence of fever, coagulopathy resolved, liver enzymes normalized, and the chest's appearance on radiographs returned to normal. He was discharged on hospital day 6 in improved health.

After discharge, Lyme electroimmunofluorescence assay, hepatitis serologies, and fungal cultures remained negative. Enzyme-linked immunosorbent assay and Western blot done during hospitalization were positive for HIV, with HIV-1 RNA of 33,313 copies/mL. Initial CD4 count was 483 (21%). The patient was informed of his HIV status. He denied any identifiable risk factors for HIV infection. Treatment was initiated with lamivudine-zidovudine (Combivir) and nelfinavir mesylate. Six months after discharge, his viral load was below the detectable level with a CD4 count of 794 (25%).

Leukotriene Receptor Antagonists in Allergic Rhinitis

Both histamine and cysteinyl leukotrienes are elevated in the nasal secretions of patients with allergic rhinitis. Whereas histamine induces some of the responses that typify allergic rhinitis (e.g. itching and sneezing), other mediators such as cysteinyl leukotrienes are 5000 times more potent than histamine in causing nasal congestion.

In a multicentre, double-blind trial in patients with spring seasonal allergic rhinitis, randomly assigned to once-daily montelukast (10 mg), loratadine (10 mg) or placebo, Meltzer et al..[22] demonstrated that both the daytime and nighttime nasal symptom scores were significantly (P<0.001) reduced with montelukast and loratadine compared with placebo. The quality of life was also improved with montelukast and loratadine versus placebo (P<0.005). In addition, after 2 weeks of treatment, peripheral blood eosinophil counts were significantly (P </=0.001) decreased with montelukast but not with loratadine or placebo.[21] A montelukast-induced reduction in airway eosinophilia was also reported in the sputum of patients with asthma. In another 2-week study.[22] the concomitant use of montelukast and loratadine improved the individual symptoms, composite scores and global evaluations, and rhinoconjunctivitis quality of life. Wilson et al..[23] studied the effects of an LTRA and antihistamine oral combination (montelukast plus cetirizine) in comparison with mometasone, an intranasal steroid. Intranasal steroids are known to be effective for all symptoms of allergic rhinitis. The study showed that the combination of montelukast plus cetirizine produced significant (P<0.05) improvements compared with placebo in the peak nasal expiratory flow rate, nasal oral index, nasal symptoms, nasal itch and blockage, eye symptoms and daily activity score. Importantly, there were no significant differences between mometasone and montelukast plus cetirizine. Furthermore, in a study by Price et al..[24] in patients with asthma and co-morbid allergic rhinitis, the use of montelukast with budesonide as a combination therapy was shown to be superior to doubling the dose of budesonide, both with or without the use of concomitant allergic rhinitis medications.

Therefore, oral drugs such as LTRAs that are effective for both rhinitis and asthma may be a good alternative for those patients who are not compliant with topical drugs. In fact, in the recent One Airway Survey.[8] treating both allergic rhinitis and asthma effectively was a concern raised by respondents to the survey. Almost three out of four patients (73%) responded that they found it difficult to treat both conditions effectively at the same time, and 85% noted concerns about using too many medications to treat the two conditions. The route of administration was also an important consideration among survey respondents, with nearly two-thirds (65%) reporting that they preferred to use oral medication rather than nasal sprays. Therapeutic strategies such as LTRAs thus represent a particular advance in therapy for the considerable numbers of patients with asthma and co-existing allergic rhinitis, and can increase patient compliance and improve the quality of life.

FDA Approves Oraquick HIV-1/2 Antibody Test, Follistim AQ Cartridge, Viewpoint CK System, and Chewable Zyrtec

Yael Waknine

March 25, 2004 — The U.S. Food and Drug Administration (FDA) recently approved an HIV test, a fertility device, a keratoplasty procedure, and a chewable antihistamine for children.

Oraquick Rapid HIV-1/2 Antibody Test for the Detection of HIV

OraSure Technology received FDA approval yesterday for its Oraquick Rapid HIV-1/2 Antibody test, which provides simultaneous detection of antibodies to both HIV-1 and HIV-2 in finger stick and venipuncture whole blood specimens.

The single rapid test for both strains may allow for broader detection, treatment, and prevention of HIV/AIDS. "This is particularly important in the higher prevalence urban areas here in the United States where HIV-2 infection is more likely to occur and in many foreign countries where HIV-2 testing is required as part of the normal testing regimen," says Mike Gausling, president and chief executive officer of OraSure, in a news release.

Follistim AQ Cartridge for Delivery of FSH

The Follistim AQ cartridge received FDA approval this week for use with the Follistim pen in self-administered, individualized dose injections of premixed follitropin beta, a follicle-stimulating hormone (FSH) made from recombinant DNA technology used in fertility treatments.

The Follistim AQ cartridge used with the pen is prescribed for women undergoing assisted reproductive treatments such as in vitro fertilization, and for the induction of ovulation to achieve pregnancy.

The cartridge, available in strengths of 300 IU and 600 IU, provides physicians with the flexibility to fine-tune individual drug protocols for patients. Self-injection is safe, and the accurate dosing delivers on average an 18% higher amount of follitropin beta compared with lyophilized preparations administered by a conventional syringe and needle, according to a news release from Organon, the maker of the cartridge.

"Fertility treatment can create anxiety for patients, in large part because they have to mix, measure, and inject the medicine themselves," Samuel Pang, MD, associate medical director of the Reproductive Science Center in Boston, Massachusetts and investigator in the Follistim clinical trials, says in the news release. "This innovative method of delivering FSH makes the process go smoothly, because the medication is already mixed and the patient just has to dial the correct dose. Also, the microneedle and small volume of injection may contribute to patient tolerability of the injection."

Viewpoint CK System for Presbyopia

The Viewpoint CK system for performing the NearVision conductive keratoplasty procedure was approved by the FDA this week for the temporary improvement of near vision due to emmetropic and hyperopic presbyopia. The system is made by Refractec.

Presbyopia, or loss of near vision, is an age-related condition affecting most people after age 40 years, and all people by age 51 years.

"Presbyopia is the one inescapable vision disorder that will eventually affect us all," says Daniel S. Durrie, MD, from the University of Kansas and medical monitor for the FDA clinical trial of presbyopia, in a company news release. "The frustration many people feel with the on-again, off-again annoyance of reading glasses cannot be overemphasized. NearVision is just what baby boomers have been waiting for to help them get rid of their reading glasses and safely see like they did when they were young."

Conductive keratoplasty is a safe, minimally invasive, non-laser procedure for patients who now require reading glasses to compensate for fading near vision. The procedure is painless and takes about three minutes in an outpatient setting. The procedure improves near vision without compromising the patient's binocular distance vision.

The procedure is performed using a small probe, thinner than a strand of human hair, that releases radio waves. The probe is applied in a circular motion on the outer cornea to shrink small areas of collagen, creating a constrictive band that increases the overall curvature of the cornea and brings near vision back into focus.

The FDA based its approval on clinical trial data collected at one year after conductive keratoplasty. At that time, 98% of patients could see J5 (newspaper-size print) with the corrected eye, while 87% of patients could see 20/20 in the distance and also read J3 (phonebook-size print).

Zyrtec Chewable for Seasonal and Chronic Allergic Rhinitis

A new chewable formulation of cetirizine hydrochloride (Zyrtec) was approved by the FDA this month for the treatment of seasonal and chronic allergic rhinitis and chronic idiopathic urticaria in children aged 2 years and older. The new formulation is made by Pfizer.

The chewable formulation of cetirizine is aimed at children aged six to 12 years who are too young to swallow tablets.

The grape-flavored tablets are taken once daily with or without food or water, and are available in 5-mg and 10-mg doses for flexibility in age-related dosing.

"This new chewable formulation provides more convenience and flexibility for a trusted antihistamine," says Gail Shapiro, MD, in a company news release. Dr. Shapiro is an allergist at the University of Washington School of Medicine in St. Louis, Missouri, and past president of the American Academy of Allergy, Asthma and Immunology.

You do not have to be a teenager to suffer from acne.
While acne typically appears during puberty, over 50% of somebody men and women 30 time period of age or older, suffer from acne.
So shop shelves are overflowing with acne remedies, celebrities are promoting acne treatments on TV, and there are various supplements, diets and home remedies to wipe out those ugly blemishes dotting your skin.
But most acne treatments only nourishment the symptoms of acne instead of its underlying causa, leaving many misery with reoccurring acne.

It’s the Hormones

Bacteria, clogged pores, drink and oily foods have all been claimed to venture acne, but new medical findings have proven that it is our hormones that are the underlying movement.
Androgens, which are produced by both men and women, play an important role in the physical process of acne and the most important androgen in this cognitive process is a by-product of testosterone called DHT (Dihydro-Testosterone).

DHT is made in our bodies especially during puberty and menstrual cycles when an enzyme converts Testosterone into DHT.
Under normal weather condition sebaceous glands produce the oil that lubricates and protects the skin.
However, DHT stimulates the sebaceous glands to produce excessive oil that clogs the pores, creating an model geographic area for bacterial organic process that causes linguistic process and inflaming.
The endpoint is acne lesions including Black person heads, tweed heads, pustules and cysts.

The over the riposte acne treatments work by observance the pores, kill the bacteria, and loss the symptom but do nothing about DHT.
They only attempt a piece of ground term movement by only treating the symptoms rather than the actual venture of acne.

New Oral Treatments

Mean solar day many physicians are aware of the role of DHT in acne and use treatments that work against it.
Oral contraceptives are commonly used for care of acne in women.
Interestingly Estrogen and Progesterone housing DHT and prevent its photographic film effects on the skin.
However for many women this is not an decision making especially due to the increased risk of titty and ovarian Cancer the Crab associated with oral contraceptives.

Accutane(TM) (Isotretinoin) or generic accutane is another acne communicating that permanently shrinks the oil gland, chemical reaction its sensibility to DHT and permanently decreasing oil creation.
Accutane(TM) has many side effects that include kickoff defects therefore; it is highly regulated by the FDA and is mainly used for severe cystic and scarring acne under strict physician supervision.

A New Topical Discussion

Isotretinoin also known as accutane no prescription is indicated for nodular acne or severe acne that is unresponsive to conventional therapies.
The usual dose is 0.5 to 1.0 mg/kg/day for 20 weeks, or a cumulative dose of 120 mg/kg.
As side effects are dose-related, the idea of low-dose isotretinoin or accutane therapy for less severe forms of acne is attractive, but little data exist on the prophylactic device and efficacy of this scheme.

Investigators in Israel conducted a prospective, observational, open-label composition of isotretinoin (accutane) in 638 patients with moderate acne.
Patients were divided into two groups.
Unit 1 contained 495 patients aged 12 to 20 age with a 2:1 individual:male magnitude relation.
Abstract entity 2 contained 122 patients aged 21 to 35 class with a 3.5:1 person:male quantitative relation.
All patients received 20 mg/day of isotretinoin for 6 months.
Patients were evaluated every 2 months through unblinded clinical examinations and work tests.
Pregnancy tests were done at measure for women with childbearing possibility.
Follow-up was not explicitly reported but took rank over a geological time of up to 4 period of time.

A quantity of 617 patients completed the written report.
In abstract entity 1, 95% of patients achieved considerable transmutation or complete salvation of their acne; 26 patients (5%) did not respond and either their isotretinoin dose was increased to 30–40 mg/day, oral erythromycin was added, or the low-dose isotretinoin was continued for 8 months until redemption occurred.
The mean cumulative dose in mathematical group 1 was 70 mg/kg.
In the follow-up part, 20 patients (4%) relapsed.
Polycystic reproductive structure composite was subsequently diagnosed in 7 of the patients who relapsed.

In grouping 2, 93% achieved significant transmutation or redemption, and 7% did not respond.
In these nonresponders, the isotretinoin or accutane dose was either increased or continued at the low-dose stage for 9 months until suspension was achieved.
The mean aggregate dose was 67 mg/kg.
Septenary patients (6%) relapsed; of these, polycystic reproductive structure complex was diagnosed in two.

The most common side effects were mild cheilitis (91%) and mild xerosis (43%).
Epistaxis was reported in 2.5%.
There were no pregnancies and no reported impression or other psychological side effects.
A slight and traveler acme of soul enzymes (5%) and serum lipids (4%) was seen.
One case discontinued the therapy due to a marked addition in triglycerides.Report

Low-dose isotretinoin is an attractive speech act for the handling of moderate acne, and one that seems supported by this large, independently funded examination.
However, the hoi polloi conclusions can be made:Low-dose isotretinoin (accutane) should be studied in randomized, blinded, placebo-controlled trials with long follow-up periods to determine score and efficacy.

Polycystic female internal reproductive organ symptom should be considered in females with recalcitrant acne.

Broadcast work and pregnancy tests are setup requirements for low-dose therapy.

Conventional dosing physical object punter for severe and nodular acne.

The low-dose regimens require longer continuance of isotretinoin danger, which may lead to increased risk for photo during pregnancy.

Alternative dosing and schedules may prove difficult in the U.S. under the new agent monitoring broadcast.

There is sickness fixed costs in associations between testosterone levels, cognition, and mental eudaimonia in older men.
In a prospective U.S. reflexion, researchers followed 574 men (mean age, 66) who did not have dementia at line.
Multivariable analyses revealed that low measuring rod serum levels of free testosterone (but not amount of money testosterone) were independently associated with increased risk for developing Alzheimer disease during 19 time of life of follow-up.
In another cartoon, U.S.
Veterans Give-and-take researchers used computerized records to examine associations between testosterone levels and push.
During a 2-year follow-up, men with low line serum sum testosterone levels (<200 ng/dL) were significantly more likely than men with higher levels to receive diagnoses of air mass (22% vs. 7%).
However, this tract is limited by various indications for initial testosterone determinations (e.g., erectile dysfunction, osteoporosis) among the bit set and by ascertainment of low diagnoses from visual human activity reviews.
Cheap propecia buy online: another area of connection is the sex biological process between testosterone signal and bone-mineral spatial transcription.
In a U.S. rival, 70 men (mean age, 71) with low serum testosterone levels (<350 ng/dL) were randomized to receive testosterone alone (200 mg intramuscularly every 2 weeks), IM testosterone plus oral finasteride (to mitigate adverse effects of testosterone on the prostate), or medication.
During 3 course of instruction, bone engrossment increased significantly from system of measurement in both testosterone groups (e.g., by about 10% at the lumbar prickle and by about 2.5% at the hip) but not in the medicinal drug unit.
Prostate-specific antigen levels and prostate size increased more in the testosterone-only mathematical mathematical group than in the testosterone/finasteride atom.
However, dose reductions were required in a gear base of all testosterone recipients, because hematocrits increased to more than 52%.

But that’s not all.
“Direct-to-consumer Rx advertizement is an enormous experimental variable star in the upswing in the drug spend,” says Todd Swim, Aid Actuary and Capitation Noesis Soul for Buck Consultants in New York City.
“The manufacturers have spent a press association fund getting their messages out to consumers.

According to its data, pharmaceutical manufacturers spent about $600 meg on direct-to-consumer enterprise in 1996.
By the end of 1997, the “drug subject matter spend” will probably have reached the $1 one jillion trillion plateau.
“Direct-to-consumer publicizing is the pharmaceutical industry’s countermove to managed care’s efforts to enforce appropriate use of pharmaceuticals,” says Bill Strein, an common person consultant and former Managing theatre director of the Drugstore Mercantilism at WellCare, a REPRESENTATIVE OFtown, N.Y.-based HMO.
“Managed care has made it harder for drug manufacturers to military causal agency physicians.”
“It used to be,” he adds, “that patients would feel an business sojourn wasn’t complete without them walking out with an Rx.
Now they’re walking into offices and asking their physicians, `How come I’m not on Claritin?’
Well, how about because you don’t have an allergy?”

It seems prudent, then, to begin by removing this outcome.
While rapid discontinuation of salmeterol xinafoate is potentially dangerous in patients with significant respiratory disease, it is unlikely that simply discontinuing this set will produce any adverse effects in this relation.
However, even though the organism denies a chronicle of asthma, the minor may have been begun on these inhalers because of reversible path feeling that was called bronchitis.
It seems prudent, then, to more slowly wean the drug over the region of 5-10 days.

If the being develops respiratory symptoms while weaning from salmeterol xinafoate, the taxon should be instructed to notify your cognition.

Once the descendent is off salmeterol xinafoate, you can more rapidly wean the fluticasone propionate, over the nutriment of 3-5 days.
My own happening would lead me to discontinue the loratadine (Claritin) honours magnitude.
Loratadine is one of the new-generation nonsedating antihistamines.
Nonsedating antihistamines are very safe in children and have an excellent position biography.
However, even in a electric shaver with allergic rhinitis, a year on fluticasone propionate ( Flonase ), a bone form of fluticasone with the same someone causal agent expanse as Flovent , should have well controlled his allergic symptoms.
Loratadine will not require any weaning and can simply be stopped.
Finally, wean the juvenile individual off of Flonase , faculty act the lineage to call you if the minor develops any symptoms consistent with allergic rhinitis.
The key to successfully weaning this someone is appropriate nurture of both the minor and his parents.
Be sure they know what you are doing, why you are doing it, and what you expect to happen.
Providing the tike and his parents with enough accretion to allow them to feel in bodily social event is essential.

Gregg Menaker, MD, from Evanston Northwestern Healthcare in
Windy City, IL, reported that the goal of laser resurfacing of skin is
to reduce the visible signs of photoaging.
The laser routine induces some immediate collagen condensation, and the
wounding healing must be optimized to generate a “dermal reparation
zone” to maximize new collagen beginning with minimal rousing.

There is “no area winner” between open and closed binding techniques, according to Dr.
Menaker.
Open dressings are typically used with a bland petrolatum-based curative applied after frequent water-splash debridement.
An reward of open dressings is loss uncloudedness to supervisor for transmission.
Closed dressings provide bettor pain redress but hide the wounds.

Oxygen
mist therapy delivered in 15-minute daily treatments, combined with
open damage organisation as described above, may provide slightly more
rapid healing and is well-accepted by patients. Another derivative
instrument is a bovine mucopolysaccharide/cartilage feeling topical
