Skin in Health and Disease

Some Topics

  • Psoriasis

    Psoriasis is a complex disorder involving immune attacks in skin with chronic inflammation and overgrowth of the upper layers of skin. Psoriatic plaques are covered with thick silvery scales which shed at an alarming rate - super dandruff. The disease usually involves the extensor surfaces of the body - the opposite to eczema which prefers the flexor surfaces. Psoriasis tend to be a chronic disease lasting years to decades and in some patients follows and erratic course - flaring and subsiding in cycles lasting many months.

    People with extensive psoriasis tend to suffer stoically and are often unwilling to bare their body in public - swimming pools and beaches are of limits for some because of embarrassment about the skin lesions which do look rather menacing to onlookers who are not familiar with the disease. Swimming in salt water and sun exposure is often helpful. Ultraviolet light treatment has been used as a standard therapy. For years people have been treated with coal tar baths followed by ultraviolet light exposure with benefits. Now, of course, we are warning people against ultraviolet light exposure and have concerns about the carcinogenic potential of coal tar.

    Psoriasis affects 1.5 % to 2.0 % of the population in western countries with Equal incidence in males and females There is genetic tendency: when one parent has psoriasis, 8 % of offspring develop psoriasis, and when both parents have psoriasis, 41 % develop psoriasis. Class I antigens associated with psoriasis are: HLA-B13, -B17, -Bw57, -CW6.

    Little progress has been made in understanding and treating Psoriasis - it is one of the many immune-mediated diseases that rage-on unchecked. Medical treatments have not been very helpful and for many years psoriasis has been a target of dubious marketing practices - numerous creams and lotions have been offered to treat the disease. Coal tar derivatives and peeling agents have been the most plausible treatments but offer little relief. Even the steroids - the all purpose drugs for skin disorders - are disappointing. Psoriatic plaques tend to be good breeding grounds for bacteria and fungi, so that secondary infection is almost inevitable. Topical antifungal agents (such as Nizoral shampoo) may be helpful, but there is little evidence that infection is the initial cause of the problem.

    Even the steroids, the all-purpose drugs for skin disorders, are disappointing. Synthetic vitamin A analogues can reduce the skin growth abnormalities in psoriasis. Tazarotene in an aqueous gel has been effective even on thick plaques on the knees and elbows. The strongest immune-suppressant drugs such a cyclosporine can control psoriasis but at high risk of developing other, more serious health problems. When cyclosporine is given to patients who have received psoralen with UV light therapy, they have, for example, a 7-fold increase in the incidence of squamous cell skin cancer.

    Agents that block tumor necrosis factor have been presented as a breakthrough in therapy, effective in treating plaque psoriasis and psoriatic arthritis. In 2005, an intense marketing effort persuaded at least half the dermatologist in the US to use these agents. Unfortunately, behind the hype, there is some bad news. While anti-TNF antibody is in theory a smart strategy for blocking immune activation, the proposal to use this treatment long-term incurs high cost plus complications and serious hazards. Anti-TNF drugs can improve arthritis and psoriasis but paradoxically, they cause a surprising number of skin diseases, including psoriasis. Flendrie et al reported that 25% of patients treated with anti-TNF drugs required consultation with dermatologists. The events recorded most frequently were skin infections, eczema, and drug-related eruptions. Other events with a possible relation to TNF-a-blocking therapy included vasculitis, psoriasis, drug-induced systemic lupus erythematosus, dermatomyositis, and a lymphomatoid-papulosis-like eruption. An increased incidence of tuberculosis has been described as well as a growing number of serious infections with fungal, mycobacterial, and intracellular bacterial pathogens.

    Psoriatic arthritis occurs in 5% to 8% of patients with psoriasis. There are two types:

    1. Mild, single joints - involving, asymmetrically, a few distal interphalangeal joints of the hands and feet: 2. Aggressive psoriatic arthritis with bone erosion and ankylosis involving the sacroiliac, hip, and cervical areas with ankylosing spondylitis; seen especially in erythrodermic and pustular psoriasis.

    Nail Abnormalities

    Pitting, yellow-brown discoloration and deformation of finger and toe nails are common; 51.8% of patients suffered from pain-caused by the nail changes, and a large group of patients was restricted in their daily activities, housekeeping and/or profession

    Skin and nail growth disturbances are secondary to an immune cell infiltration of the skin and the release of immune mediators (cytokines) which promote cell growth and inflammation at the same time. Evidence suggests that T-lymphocytes lead the attack on the skin. Although psoriatic plaques tend to be good breeding grounds for bacteria and fungi, it is doubtful that infection is original cause of the problem.

    Is Psoriasis Food Allergy?

    Trent and Kerdel described the immune activity in psoriatic skin: “The 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 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. These cytokines are responsible for keratinocyte proliferation and lack of maturation, and vascular changes characteristic of psoriasis.”

    I would edit their description by stating: “the process begins with the presence of food antigens in the skin.” Food proteins that enter the body through a leaky digestive tract can make their way into the skin and invite immune cells to attack. This is a delayed pattern immune response that occurs slowly and is usually not noticed by psoriasis patients and is not detected by any office or laboratory test. See delayed hypersensitivity mechanisms.

    Food antigens may arrive in the skin as immune complexes, attach to skin cells and/or are presented by resident macrophages which trigger lymphocytic activity. While this is just a theory, its better than no therapy at all and can lead to a immediate therapeutic experiment. Psoriasis responds variably to Diet Revision Therapy. In several remarkable cases, remission of psoriatic arthritis with clearing of the skin lesions has been achieved by rigorous application of the Alpha Nutrition Program.

    For moderate to severe psoriasis, we are inclined to start diet revision with an extended food holiday on Alpha ENF and use mild topical treatment include daily warm water baths with sea salts to soften the thickened skin and gentle scrubbing to remove skin scales. Topical Vitamin A gel applications to the thickest plaques is an option.

    Psoriatic skin is badly damaged and takes many weeks to heal. Food reintroduction must be slow and patient since it is easy to reactivate the disease with wrong food choices.

    NB Skin tests, blood tests for food allergy and rotation diets are not useful.

  • Skin in Health and Disease

    is a book about skin health and skin care that offers solutions to specific skin disorders. The good news for many suffers some chronic skin disorders is that complete diet revision will often improve and sometimes resolve skin symptoms. This book focuses on the most common skin disorders that can be controlled by changes in skin care, diet and the environment. Eczema, for example, is sometimes an expression of food allergy, or allergy to contact materials. Dermatologist may deny the food allergy causes, so that their patients often have to make independent decisions. In all aspects of medicine, we advocate responsible self-management and offer this book as primer and reference for self-managers with skin problems.

    The book, Skin in Heath and Disease is intended to be used with the Alpha Nutrition Program. This text provides background knowledge, helpful in understanding skin disorders and the relevance of diet revision. Often a food holiday on Alpha ENF is the best way to begin recovery and the Alpha Nutrition program is an ideal way to design a safer, healthier long-term diet. If diet revision is appropriate to solve your Skin Disorders, you can order the the Starter Pack Option.
