ABSTRACT

We report the case of a patient with cutaneous and arthropathic psoriasis for eight years, whose sudden increased severity of the clinical picture led to a diagnosis of AIDS, emphasizing the importance of the specialist in the diagnosis of systemic diseases. The appropriate therapeutic interventions, including antiretroviral therapy and the immunobiological agent etanercept, enabled rapid improvement of symptoms and quality of life of the patient, besides contributing to delay in immunodeficiency progression.

RESUMO

Relata-se o caso de um paciente com psoríase cutânea e artropática há oito anos, cujo agravamento súbito do quadro clínico levou ao diagnóstico da Aids, ressaltando a importância do especialista no diagnóstico de doenças sistêmicas. A intervenção terapêutica apropriada, incluindo a terapia antirretroviral e agente imunobiológico - etanercepte - possibilitou a rápida melhora do quadro clínico e da qualidade de vida do paciente, além de contribuir para o retardo na progressão da imunodeficiência.

INTRODUCTION

Psoriasis is a chronic inflammatory disease that affects from 2 to 3% of the worldwide population, frequently involving the skin and articulations. Its etiology is multifactorial, with participation of genetic, autoimmune and environmental factors. More recently the role of cells and inflammatory mediators in the pathogenesis of the disease was demonstrated and it is now defined as a systemic inflammatory affection of autoimmune nature1. The inflammatory symptom complex of psoriasis may be exacerbated by environmental factors, including viral infections, mainly HIV infection.2 Articular involvement may take place in 6 to 42% of patients with skin psoriasis, with variable spectra, from non-erosive to severe and debilitating arthritis. Such clinical pictures should be differentiated from reactive arthritis, which is characterized by the triad polyarthritis, urethritis and conjunctivitis, together with the typical skin lesions. Studies also show that in patients with HIV/AIDS, articular involvement is usually more extensive and refractory to the customary therapy.3

This paper presents a case of cutaneous and arthropathic psoriasis, whose sudden clinical picture exacerbation led to AIDS diagnosis, highlighting the importance of the dermatologist in the diagnosis of systemic diseases. The appropriate therapeutic intervention, including antiretroviral therapy and the immunobiological agent etanercept, resulted in rapid improvement of the clinical picture and quality of life of the patient.

 

CASE REPORT

Clinical Picture: A 32-year-old male patient, single, was diagnosed with cutaneous and arthropathic psoriasis in 2002. As the skin lesions regressed soon after the beginning of treatment, the patient was monitored only through rheumatology, using methotrexate (MTX), 15mg/week, since the diagnosis (cumulative doses of 5040mg), with good clinical control of the disease. In June 2009, new skin lesions appeared, associated with marked recrudescence of the articular involvement and 10kg weight loss. The onset of skin lesions was the motive for referral to dermatology. Dermatological examination: presence of erythematous-squamous plaques, some of them with crusts, predominantly in the inguinal, palmo-plantar regions and back of hands (Figure 1). Articular Examination: arthritis in the proximal and distal interphalangeal articulations of hands, metacarpophalangeal articulations, wrists and thigh-femoral articulations. At the initial examination, PASI (Psoriasis Area and Severity Index) score was 19 (Figure 2). Supplementary tests: positive serology for HIV, with a T CD4+ cell count of 217 cells/mm3 and viral load of 11,000 copies/mm3. Negative VDRL. Radiography with varied alterations in small and large articulations, decreased articular spaces and formation of osteophytes. Computerized tomography (CT) revealed sclerosis, cortical irregularity, marginal osteophytes in the sacroiliac joints and bilateral acetabular cortical irregularity. Normal bone densitometry. Reactive Protein C: 12. Negative serology for Chlamydia trachomatis IgG and IgM. Rheumatoid factor negative. HLA B27 antigen search negative. Ophthalmological examination normal, ruling out uveitis. Histopathology compatible with psoriasis. Conduct: MTX suspended and acitretin introduced at the dosage of 30mg/day, associated with antiretroviral therapy (zidovudine, lamivudine, lopinavir and ritonavir). Progression: After 60 days of treatment, new lesions appeared on the trunk, nail lesions worsened, with onychodystrophy, onycholysis and "oil stains" on all 20 nails, with great exacerbation of the articular picture, severe arthritis of large and small articulations, in addition to pain that was refractory to powerful analgesia, making it impossible to walk and perform simple daily tasks (Figure 2). At this time, PASI was 29. This clinical recrudescence determined the introduction of etanercept, at an induction dose of 50mg 2x per week, with a maintenance dose of 50mg per week. After 60 days of treatment, there was significant improvement of the cutaneous-articular symptom complex, with a PASI of 6.9 (Figure 3). The patient continues to be monitored through dermatology and infectology, using antiretrovirals and etanercept, without skin lesions and with significant improvement of the articular symptoms.

 

DISCUSSION

Since the beginning of the AIDS epidemic, a worsening of psoriasis progression is observed in patients with HIV infection, with sudden exacerbation of the clinical picture, onset of extensive cutaneous lesions, ungual and palmo-plantar expressive involvement, in addition to more aggressive articular affection, as occurred in the reported case.4 Some studies also suggest a relationship between immunosuppression progression and severity of psoriasis, above all with T - CD4+ lymphocyte count below 400 cells/mm.5, 6

The differential diagnosis of articular manifestations should be done with reactive arthritis, characterized by the presence of the triad polyarthritis, urethritis and conjunctivitis, accompanied by the typical skin lesions. It affects more often young men and is a characteristic of association with HLA-B27, which is present in around 80-90% of patients.7 In the case reported, the absence of urethritis and uveitis, as well as the negative results of the search for HLA B-27 and serology for Chlamydia trachomatis rule out the diagnosis.

As regards the treatment of cases of psoriasis exacerbated by HIV infection, many studies show that the introduction of antiretroviral therapy (ARVT), associated with conventional psoriasis treatments, improves the lesions and the quality of life of these patients8. Other studies also mention that the interruption of ARVT may worsen the cutaneous-articular symptom complex. In some cases, however, the conventional treatments do not present such an adequate response, progressing to severe and incapacitating cutaneous-articular clinical pictures. During a long time biological agents were not recommended in these cases, for fear of increasing the risk of severe opportunistic infections9. Nevertheless, in the last few years, studies did not show evidence of significant increase in opportunistic infections with the use of biological medications for these patients, especially etanercept, indicated in severe psoriasis cases refractory to conventional therapy. However, serious clinical-laboratory control should be in place for early diagnosis of potential infectious complications, in addition to the adequate antiretroviral therapy. 10,11,12

In the case reported, the indication of etanercept occurred as a result of the severe and incapacitating articular symptom complex, associated with recrudescence of skin lesions. The clinical improvement after introduction of etanercept was satisfactory, with the patient reaching PASI 90 within 60 days of treatment. The patient has been monitored for one year, with total remission of cutaneous lesions and substantial improvement of the articular involvement.
