Diagnosis and underdiagnosis of comorbidities in psoriasis patients - need for a multidisciplinary approach

Abstract BACKGROUND: Psoriasis is an immune-mediated disease that manifests predominantly in the skin, although systemic involvement may also occur. Although associated comorbidities have long been recognized and despite several studies indicating psoriasis as an independent risk factor for cardiovascular events, little has been done in general medical practice regardind screening. In the United States, less than 50% of clinicians are aware of these recommendations. OBJECTIVE: To identify the prevalence of these comorbidities in 296 patients followed up at a university dermatology clinic. METHODS: Systematically investigated comorbidity frequencies were compared with general practitioners' registry frequencies. Clinical features correlated with comorbidities were also investigated. RESULTS: High prevalences of systematically investigated comorbidities such as hypertension (30%) and dyslipidemia (26.5%) were documented. Conversely, data from general practitioners' records showed that 33% of dyslipidemia cases were undiagnosed and indicated possible underdiagnosis of some comorbidities. Furthermore, an association was found between: the number of comorbidities and psoriasis duration, age and high body mass index an association was found between the number of comorbidities and psoriasis duration, age, high body mass index, waist circumference or waist-to-hip ratio. (p<0.05). CONCLUSION: Disease duration, age and high body mass index, waist circumference or waist-to-hip ratio are possible criteria for choosing which patients should be screened for comorbidities. Underdiagnosis of comorbidities by general practitioners highlights the need for a multidisciplinary approach in psoriasis management.

Psoriasis and obesity: literature review and recommendations for management.

Recent studies have found a relationship between obesity and chronic inflammation, confirmed by the association of high levels of tumor necrosis factor (TNF-_), interleukin six (IL-6,) and reactive C-protein with an increase in body mass index (BMI). In obese individuals, this inflammatory condition could contribute to the development or aggravation of psoriasis. Analogous phenomena have already been described in other inflammatory chronic diseases, such as rheumatoid arthritis and Crohn's disease. Epidemiological studies have identified a high prevalence of cardiovascular comorbidities, secondary to the metabolic alterations associated with psoriasis and obesity. A few aspects of this association remain unclear, such as the impact of obesity in the clinical forms of dermatoses, in the response to treatment, and its relationship with comorbidities.

Psoríase e obesidade: revisão de literatura e recomendações no manejo: [revisão] / Psoriasis and obesity: literature review and recommendations for management: [review]

Estudos recentes demonstram uma relação entre obesidade e inflamação crônica, confirmada através da associação de níveis elevados de fator de necrose tumoral alfa (TNF-±), interleucina seis (IL-6) e proteína C reativa, com aumento do índice de massa corporal (IMC). O estado inflamatório, nos indivíduos obesos, poderia contribuir para o desenvolvimento ou agravamento da psoríase. Fenômenos análogos já foram descritos, em outras doenças inflamatórias crônicas, como a artrite reumatóide e doença de Chrõn. Estudos epidemiológicos mostram uma prevalência elevada de comorbidades cardiovasculares, secundárias às alterações metabólicas, associadas à psoríase e obesidade. Permanecem ainda não elucidados alguns aspectos desta associação, como: o impacto da obesidade (nas formas clínicas da dermatose, na associação com comorbidades e na resposta ao tratamento).

Infective dermatitis and human T cell lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis in childhood and adolescence.

BACKGROUND: Human T cell lymphotropic virus type 1 (HTLV-1)-associated infective dermatitis (IDH) is a chronic and recurrent eczema occurring during childhood and adolescence. HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic myelopathy of adulthood, presenting with slowly progressive spastic paraparesis and sphincter dysfunction with mild sensory involvement. There are few reports describing an association between IDH and HAM/TSP. The objective of this study was to evaluate the occurrence of HAM/TSP in patients with IDH and in seropositive members of their families and to determine the blood levels of antibodies against HTLV-1 in patients with HAM/TSP. METHODS: Twenty patients with IDH and their seropositive mothers and siblings underwent clinical, neurological, and laboratory evaluations. The diagnosis of HAM/TSP was made in accordance with the World Health Organization criteria. RESULTS: Nine individuals had HAM/TSP (6 of the patients with IDH, 2 mothers, and 1 seropositive brother). In 3 families, > 1 individual had HAM/TSP. The serum antibody titers of the patients with HAM/TSP varied from 1 : 3.125 to 1 : 78.125. CONCLUSIONS: A strong association was observed between IDH and HAM/TSP. The familial clustering of both diseases suggests a genetic background. Serological screening for HTLV-1 in children with symptoms of myelopathy is essential in areas where HTLV-1 is endemic.

Infective dermatitis associated with the human T cell lymphotropic virus type I in Salvador, Bahia, Brazil.

BACKGROUND: Infective dermatitis associated with human T cell lymphotropic virus type I (HTLV-I) infection is a chronic, relapsing eczema of childhood. METHODS: Children, their mothers, and their siblings underwent serological testing for HTLV-I. Epidemiological data were collected from all seropositive children and their family members, and clinical and dermatological examinations were performed. Laboratory studies, including skin culture, and histopathological analyses were also performed. The diagnosis of infective dermatitis associated with HTLV-I (IDH) was made according to previously established criteria. RESULTS: All of the patients with cases that demonstrated clinical aspects of IDH were positive for HTLV-I. The median age of the children at the time of the first visit was 8.0 years (range, 2-14 years). The median duration of breastfeeding for 19 children was 22.5 months (range, 1-48 months). The lesions were erythematous, scaly, exudative, and crusted in all cases. The scalp, retroauricular areas, neck, and groin were the regions that were commonly affected. Cultures were positive for Staphylococcus aureus for 95% of the patients. The children were followed-up for a median of 3.0 years (range, 0.1-7 years), and 5 children developed HTLV-I-associated myelopathy/tropical spastic paraparesis. All of the children except 1 were treated with sulfamethoxazole-trimethoprim, and their lesions either improved greatly or completely disappeared. CONCLUSIONS: The present study demonstrates the severity of IDH in Bahia and confirms that its diagnosis is based almost exclusively on clinical aspects of the disease. Serological testing for HTLV-I and careful follow-up is recommended for all children with chronic, relapsing, severe eczema in regions where HTLV-I is endemic.
