Psoriasis is a chronic inflammatory skin disease. Associated comorbidities or risks may include psoriatic arthritis, obesity, depression, smoking, diabetes, hyperlipidemia, an increased risk of cardiovascular disease with myocardial infarction, or an increased risk of lymphoma. The clinical presentation of psoriasis can range from the more common red scaling elevated plaques on the elbows, knees, or scalp to the less common superficial pustules scattered on the palms or soles, or in rare cases wide-spread pustules on the body. More specifically, the clinical spectrum of psoriasis includes the plaque, guttate, small plaque, inverse, erythrodermic, and pustular variants. The determinants of the clinical severity of psoriasis, the risk of comorbidities, and the quality of life of a psoriatic patient are influenced by multiple factors. At the minimum, these include variations in the quality and type of psoriasis, the quantity of skin involved, and the distribution of skin lesions (including special areas such as the scalp, nails, face, intertriginous regions, and palmoplantar surfaces). Objective measures used to quantify the severity of psoriasis, including the body surface area involved, Physician's Global Assessment, Psoriasis Area and Severity Index, and quality of life measures, are all assessments that can be useful in guiding approaches to management and therapeutics. In this paper, we review the clinical spectrum of psoriasis, the differential diagnoses, measures and determinants of severity, and the recommendations on when to refer a patient to a specialist in psoriasis. We also briefly review the comorbidities, and note the importance of referring the psoriatic patient to the internist/general practitioner for evaluation and management for these comorbidities.

Salacia reticulata is a native plant of Sri Lanka. In the traditional medicine of Sri Lanka and India, Salacia reticulata bark is considered orally effective in the treatment of rheumatism, gonorrhea, skin disease and diabetes. We have investigated, both in vivo and in vitro, whether the leaf of Salacia reticulata (SRL) can ameliorate collagen antibody-induced arthritis (CAIA) in mice as the rheumatoid arthritis (RA) model. The mice were fed a lard containing chow diet (AIN-93G) or the same diet containing 1% (w/w) SRL powder. All mice were bred for 23 days. On day 7 or 14 after LPS injection, mice were killed, and tissue and blood samples were collected. Histological analysis was performed, and serum levels of inflammatory mediators and the mRNA levels of inflammation-related genes and osteoclast-related genes were measured. SRL treatment ameliorated the rapid initial paw swelling, inflammatory cells infiltration, skeletal tissues damage, osteoclast activation and the mRNA levels for osteoclast-related genes compared with the CAIA mice. However, the serum and mRNA levels of inflammatory mediators did not differ between the CAIA mice and the SRL-treated mice. SRL might reduce the inflammatory cells induction and skeletal tissue degradation by CAIA by the regulating osteoclastogenesis.

Acquired perforating dermatoses (APD) is an uncommon skin disorder seen in patients with diabetes mellitus, chronic kidney disease, or both together. We present the clinicopathological features of APD in patients with diabetic kidney disease and discuss the recent advances in management. We retrospectively analyzed the data of 8 patients with APD presenting to our center. All patients were known cases of Type 2 diabetes and chronic kidney disease requiring maintenance dialysis. Acquired perforating dermatoses was diagnosed based on clinical presentation of itchy, keratotic papulonodular lesions, and characteristic histopathological features of transepithelial elimination on skin biopsy. The patients were subdivided into 4 types of APD based on the biopsy features. All our patients had Type 2 diabetes over 5 years duration and were on maintenance dialysis for more than 6 months before presentation. Acquired perforating dermatoses symptoms appeared 2 to 6 months before presentation. The majority of patients (6/8) had a subtype of reactive perforating collagenosis. All the patients showed significant resolution with topical glucocorticoid therapy. Acquired perforating dermatoses is a skin complication seen in Type 2 diabetes, chronic kidney disease, or when both are present together. Early identification and therapy prevents the associated morbidity.

To clarify the molecular mechanism underlying the transepidermal extrusion of dermal collagen in acquired perforating dermatosis (APD) associated with diabetes mellitus and renal failure, we studied the interaction between advanced glycation end product (AGE)-modified extracellular matrix proteins and keratinocytes (KCs) in a cell culture system. The expression of involucrin (INV) and keratin 10 was significantly enhanced in normal human KCs grown on AGE-modified collagen I or III compared with cells grown on unmodified collagen I or III. Glycated collagens I and III preferentially induced the expression of AGE receptor CD36, but not of other AGE receptors. KCs induced to terminal differentiation demonstrated markedly elevated CD36 expression. Glycated collagen I- and III-induced INV expression was partially blocked by the anti-CD36 antibody (Ab). These substrates also induced epidermal matrix metalloproteinase 9 (MMP-9) expression. Lesional skin from APD patients reacted moderately or strongly with the anti-CD36 Ab as well as the anti-MMP-9 Ab in the epidermal cells surrounding the collagenous materials being eliminated. These results suggest that exposing KCs to AGE-modified interstitial collagen (types I and III) by scratching induces terminal differentiation of KCs via the AGE receptor (CD36), leading to the upward movement of KCs together with glycated collagen.

Psoriasis is a chronic inflammatory, immune-mediated skin disease, which may cause significant deterioration in the quality of life. Recent evidence indicates that psoriasis and psoriatic arthritis are frequently associated with cardiometabolic diseases including myocardial infarction, stroke, diabetes, obesity, dyslipidemia and non-alcoholic fatty liver disease. Although the causal relationship between cardiometabolic comorbidities and psoriasis has not yet been completely proven, it appears that obesity is a relevant risk factor for the development of psoriasis and metabolic syndrome. In addition, moderate to severe psoriasis itself is a risk factor for cardiovascular disease and the metabolic syndrome. Some common genetic traits as well as inflammatory mechanisms may underlie the development of psoriasis and cardiometabolic comorbidities. The presence of comorbidities has important implications in the global approach to patients with psoriasis. Traditional systemic anti-psoriatic agents could negatively affect cardiometabolic comorbidities, and may have important interactions with drugs commonly used by psoriasis patients. In contrast, the recent findings that the risk of myocardial infarction is markedly reduced in rheumatoid arthritis patients who respond to anti-TNF-alpha therapy compared with non-responders supports the hypothesis that the anti-inflammatory effect of TNF-alpha blockers might potentially reduce the cardiovascular risk also in psoriasis patients. Finally, patients with moderate to severe psoriasis should be treated promptly and effectively, should also be encouraged to drastically correct their modifiable cardiovascular risk factors, in particular obesity and smoking habit.

Accumulating evidence reveals that sole mutations in hENT3 cause a spectrum of human genetic disorders. Among these include H syndrome, characterized by scleroderma, hyperpigmentation, hypertrichosis, hepatomegaly, cardiac abnormalities and musculoskeletal deformities, pigmented hypertrichotic dermatosis with insulin-dependent diabetes syndrome, characterized by autoantibody-negative diabetes mellitus and skin deformities, familial Rosai-Dorfman disease, characterized by short stature, familial histiocytosis and sinus histiocytosis with massive lymphadenopathy (SHML), characterized by severe tissue infiltration of immune cells and swollen lymph nodes. hENT3 spectrum disorders share a common mutation and share overlapping clinical manifestations that display many intriguing resemblances to mitochondrial and lysosomal disorders. Although earlier studies identify hENT3 as a mitochondrial and a lysosomal nucleoside transporter, the precise connections between hENT3 and the pathophysiology of these disorders remain unresolved. In this study, we performed functional and biochemical characterization of these mutations in hENT3. We report severe reductions/losses of hENT3 nucleoside transport functions of hENT3 syndrome mutants. In addition to transport alterations, we provide evidence for possible loss of hENT3 functions in all H and pigmented hypertrichotic dermatosis with insulin-dependent diabetes syndromes due to either mistrafficking or altered stability of mutant hENT3 proteins.

It is known that diabetes mellitus (DM) motives the dermatosis cutaneous because of the proper affection, infections, medicine reactions or the diabetic foot. In this manner, the objective of this study is to work on the hypothesis and identify the influence of the dermatosis in the quality of life of the carrier of DM. It is an analytical, transversal and quantitative study, developed in the Family Health Program (PSF) at Odilom Lacerda, Planura, Minas Gerais State. The sample is composed by 47 (100%) patient carriers of DM, registered in the program called HIPERDIA. Data collection was done by a dermatologist, who applied anamnesis and a chart about the influence of the dermatosis in the quality of life during a medical consultation. The analysis of the data was numerical and percentile following the criteria: high frequency (80 to 100%), average frequency (50 to 79%), low frequency (1 to 49%) and null (for non-existent situations). All the patients of the study (47-100%) presented dermatosis and demonstrated its influence in quality of life, with average frequency for skin dryness and painful sensation in (24-51%); low frequency, especially the difficulty in the personal hygiene (19-40.3%) and the interference in the interpersonal relationship with relatives or friends (18-38.2%).

Psoriasis is a chronic inflammatory dermatosis with a relapsing course. The best known comorbidity is psoriatic arthritis. In daily clinical practise it is well known, that patients with psoriasis show more often classic cardiovascular risk factors such as obesity, Diabetes mellitus, hyperlipoproteinemia, hypertension, nicotine abuse often presenting as Metabolic Syndrome and suffer more often from coronary heart disease than patients without psoriasis. This could be demonstrated in numerous clinical and epidemiologic studies. In the last few years there is increasing evidence for psoriasis being an independent cardiovascular risk factor despite of concomitant classic risk factors. This review summarizes the current state of research and discusses possible common immunopathogenetic mechanisms.

87 patients including 64 males and 24 females with diabetes mellitus and skin diseases were studied. The skin manifestations were common during the fifth decade of life. Maturity onset diabetes had increased incidence of skin disease. Incidence of skin disease was common in early diabetes. Infections both bacterial and fungal were seen in majority of patients. Specific cutaneous markers and metabolic changes were rare and seen in long standing diabetes. Infections were the common problems which recurred subsequently.

A male patient with subcorneal pustular dermatosis was initially treated with dapsone with excellent response. Since he developed hypersensitivity to dapsone, corticosteroid was given instead of dapsone. But steroid also was withdrawn since he developed hypertension and diabetes. There was relapse of skin lesions which were treated with oral colchicine, which has profound inhibitory effects on neutrophils. There was excellent therapeutic response to colchicine and the drug well-tolerated.
