Disseminated tuberculosis associated with reactive arthritis of Poncet in an immunocompetent patient

Abstract Cutaneous tuberculosis is a rare extrapulmonary manifestation of tuberculosis which, like disseminated tuberculosis, commonly occurs in immunocompromised patients. Poncet reactive arthritis is a seronegative arthritis affecting patients with extrapulmonary tuberculosis, which is uncommon even in endemic countries. We report a previously healthy 23-year-old male patient with watery diarrhea associated with erythematous ulcers on the lower limbs and oligoarthritis of the hands. Histopathological examination of the skin showed epithelioid granulomatous process with palisade granulomas and central caseous necrosis. AFB screening by Ziehl-Neelsen staining showed intact bacilli, the culture was positive for Mycobacterium tuberculosis, and colonoscopy revealed multiple shallow ulcers. Disseminated tuberculosis associated with reactive Poncet arthritis was diagnosed, with an improvement of the clinical and skin condition after appropriate treatment.

Artritis por Parvovirus B19: Caso clínico / Parvovirus B19 arthritis: Report of three cases

Parvovirus B19 infection is highly prevalent in children and the most common manifestation is a facial rash. In adults, acute polyarthritis and skin rash are often the presenting features. We report three patients with the disease. A 40-year-old female presenting with fever, myalgias and painful swelling of elbows, knees, wrists and feet, with functional limitation, after having a respiratory infection. Additionally, an erythematous skin rash appeared in both extremities. IgM antibodies against Parvovirus B19 were positive. The skin biopsy disclosed a leukocytoclastic vasculitis. The patient was treated with anti-inflammatory drugs and antihistaminics. A 40-year-old female, presenting with skin rash and pain in wrists and hands. IgM antibodies against parvovirus were positive. The patient was treated successfully with acetaminophen. A 38-year-old male with psoriasis, presenting with generalized and progressive polyarthralgia. A Parvovirus viral load determination found 239000 copies of the virus and IgM antibodies were positive. He was successfully treated with non-steroidal anti-inflammatory drugs.

Artritis reactiva secundaria a fiebre por mordedura de rata: reporte de un caso clínico / Reactive arthritis secondary to rat-bite fever: report on a clinical case

Caso clínico: Paciente de sexo masculino, de 69 años, sin otros antecedentes. Debuta con dolor en zona de la cadera derecha transitorio, evolucionando con cuadro de seis días de desarrollo de fiebre hasta 39,2ºC, calofríos, artralgias en tarso derecho, rodillas, hombros y astenia, por lo que fue hospitalizado. Al examen destacaba aumento de volumen doloroso en rodilla izquierda y hombro derecho. El estudio de líquido articular descartó artritis infecciosa y presencia de cristales intraarticulares. Los exámenes séricos mostraban parámetros inflamatorios alterados con leucocitosis, VHS y PCR elevados. Panel viral negativo. Sin otro foco inflamatorio evidente, se inició manejo antibiótico empírico con Ceftriaxona y Cloxacilina, con buena respuesta, mejorando su sintomatología y parámetros inflamatorios. Cultivos articulares negativos. El Gram de hemocultivos demostró la presencia de bacilos Gram negativos, aislando en los hemocultivos Streptobacillus moniliformis. El paciente evoluciona favorablemente, con regresión total de su cuadro articular. Discusión y conclusión: La Fiebre por Mordedura de Rata es una enfermedad sistémica que típicamente se presenta con fiebre, rash cutáneo y poliartralgias migratorias. Uno de sus principales agentes causales es el Streptobacillus moniliformis, que coloniza la nasofaringe de ratas y otros roedores. Casos aislados han sido reportados en Chile. En la Fiebre por Mordedura de Rata hasta un 50 por ciento de los pacientes desarrolla artritis con derrame articular o sin él. Puede afectar cualquier articulación, pero la más comúnmente comprometida es la rodilla. El dolor articular disminuye en las primeras tres semanas del uso de antibióticos, pero la articulación en ocasiones puede llegar a ser destruida. En sujetos sanos se han reportado tasas de mortalidad de 10 por ciento a 15 por ciento. Mientras todos los síntomas se resuelven puede haber recaídas con graves complicaciones, como meningitis, endocarditis...

Clinical case: Male patient, 69 years old and no previous record. First episode with transitory pain in the right hip zone, going on to 6 days of fever that evolves to 39.2 ºC, shivers, articular pain in the right tarsus, knees, shoulders and asthenia, so he was hospitalized. Upon examination, painful swellings of the left knee and right shoulder stood out. A study of synovial fluid ruled out infectious arthritis and presence of intra-articular crystals. Blood tests showed altered inflammatory parameters with high leukocytes, VHS and CRP. Negative viral panel. Without another evident inflammatory focus, an empirical management was initiated by means of antibiotics with Ceftriaxone y Cloxaciline, which had a good response relieving symptoms and inflammatory panels. Negative articular culturing. The blood culture Gram showed presence of negative Gram bacilli, with the isolation of Streptobacillus moniliformis in the blood cultures. Patient evolves favorably, with full regression of his articular symptoms. Discussion and conclusion: Rat-bite fever is a systemic sickness that typically presents itself with high fever, skin rash and migratory poly-articular pain. One of its main causing agents is the Streptobacillus moniliformis that colonize the nasopharynx of rats and other rodents. Isolated cases have been reported in Chile. In Rat-bite Fever up to 50 percent of patients develop arthritis with and without joint effusion. It may affect any joint, but that most commonly compromised is the knee. Articular pain subsides in the first 3 weeks of use of antibiotics, but the joint may sometimes even be destroyed. Mortality rates in healthy individuals have been reported at 10 percent to 15 percent. While all symptoms disappear there might be relapses with serious complications such as meningitis, endocarditis, myocarditis, pneumonia and fulminant sepsis that may cause the patient to die. Timely diagnose and treatment are paramount to avoid its serious...

A Case of Poncet's Disease in a Patient with Pulmonary Tuberculosis Accompanying Erythema Nodosum / 결핵및호흡기질환

Poncet's disease is an aseptic polyarthritis developing in the presence of active Tuberculosis occurring elsewhere, and is not due to direct involvement of joints but to an immunological reaction to tuberculoprotein. We experienced a case of Poncet's disease accompanying erythema nodosum in a 55-year-old female patient with pulmonary tuberculosis. She had multiple tender erythematous nodules on both lower limbs for 3 months and a cough and sputum from one month ago. She felt severe pain in both knees and ankles with swelling one week before admission. Her chest X-ray, computed tomography (CT) scan and positive sputum AFB stain results revealed that she had active pulmonary tuberculosis accompanying erythema nodosum and aseptic polyarthritis. Her arthritis and erythema nodosum were dramatically improved within four weeks after anti-tuberculosis therapy. We report a case of Poncet's disease in pulmonary tuberculosis accompanying erythema nodosum.

Avaliação do paciente com artrite / Assessment of patients with arthritis

Artrites são manifestações clínicas de uma série de doenças. Sua classificação etiológica é muitas vezes difícil e depende de história clínica e exame físico cuidadosos. Artrite séptica e gota se apresentam mais comumente como monoartrite aguda e quadros reacionais são geralmente poliarticulares. A internação hospitalar é fator de risco para o desenvolvimento tanto de artrites reacionais quanto para crises de gota e artrite séptica. O diagnóstico precoce é muito importante a fim de iniciar o tratamento precocemente, alívio dos sintomas e preservação da funcionalidade articular. A punção do líquido sinoviale sua análise são de fundamental importância diagnóstica nos quadros de monoartrite aguda.

Arthritis are clinical manifestations of plenty of diseases. Its etiological classification is many timesdifficult and depends on careful clinical history and physical examination. Gout and skeptical arthritispresents commonly as acute monoarthritis and reactional arthritis are often polyarticular. Hospitalaradmission is a risk factor to the development of reactional arthritis, crisis of gout and septical arthritis.Early diagnosis is imperative to start early treatment, symptom relief and articular function preservation.Synovial fluid aspiration and its analysis are of critical diagnostic importance in cases of acute monoarthritis.

Uveíte das espondiloartropatias: prevalência e relação com doença articular / Uveitis and spondyloarthritis: prevalence and relationship with joint disease

OBJETIVOS: Estudar a prevalência de uveítes na população local de espondiloartropatias e sua relação temporal com achados articulares. MÉTODOS: Foram revisados prontuários de 77 pacientes com espondiloartropatias atendidos no ambulatório de reumatologia do Hospital Universitário Evangélico de Curitiba, para diagnóstico do tipo de espondiloartropatia, sexo, idade, presença e tipo de uveite, tempo decorrido entre as primeiras manifestações oculares e as articulares. RESULTADOS: Uveíte foi encontrada em 12 dos 77 pacientes (15,6 por cento), sendo anterior em 83,3 por cento dos casos. O aparecimento da uveíte foi semelhante em todas as formas de espondiloartropatia (p=0,27) e não sofreu influência do sexo do paciente (p=0,74). O tempo médio de aparecimento dos sintomas oculares em relação ao diagnóstico articular foi de 4,04 meses para artrite reativa e 73 meses para espondilite anquilosante (p=0,009). CONCLUSÕES: A uveíte encontrada em pacientes com espondiloartropatia é, na sua grande maioria, anterior. O aparecimento da uveíte em relação aos sintomas articulares é mais precoce em casos de artrite reativa do que em espondilite anquilosante.

PURPOSE: To study uveitis prevalence in the local population with spondyloarthritis and its temporal relationship with joint complaints. METHODS: We reviewed seventy-seven charts of spondyloarthropathy patients from the rheumatology clinic of the "Hospital Universitário Evangélico de Curitiba" for spondyloarthritis class, patients' sex and age, occurrence of uveitis and its location and relationship between the first episode of uveitis and initial joint complaints. RESULTS: Uveitis was found in 12 of 77 patients (15.6 percent) which was anterior in 83.3 percent of the cases, without preference for spondyloarthropathy class (p=0.72) and patients' sex (p=0.74). In patients with reactive arthritis, the mean time between uveitis appearance and joint complaints was 4.04 months and in ankylosing spondylitis 73 months (p=0.009). CONCLUSION: Spondyloarthropathy patients have uveitis that is anterior in most of the cases and that appears earlier in reactive arthritis than in ankylosing spondylitis.

The study of T cell clones of synovial fluids of reactive arthritis / 中华风湿病学杂志

Objective To compare the cytokine expression profile of 3 CD8+, 3 CD4+ and 3 gamma delta-positive T cell clones derived from the synovial fluids of reactive arthritis (ReA) patients and to explore the immunological pathogenesis of ReA. Methods Complementary DNA-based microarrays containing genes for 56 cytokines were used for screening the expression profile of 3 CD8+, 3 CD4+ and 3 gamma delta-positive T cell clones derived from the synovial fluids of 3 reactive arthritis (ReA) patients. Results Transcripts encoding for interferon (IFN)-gamma and tumor necrosis factor (TNF)-alpha were expressed among all CD8+ and CD4+ T cell clones by microarray. Expression of these cytokines could be verified by RT-PCR in 14 out of 15 microarray experiments. Lymphotoxin (LT)-alpha and granulocyte macrophage colony-stimulating factor (GM-CSF) were also consistently expressed among CD4+ cells. However, ??+T cells revealed a different cytokine pattern, mainly expressing transforming growth factor (TGF)-beta 2 and GM-CSF. Conclusion CD8+ and CD4+ T cells mainly reveale a Th1-mediated profile, whereas ??+T cells expresse less pro-inflammatory cytokines resembling a Th3-driven pattern. T lymphocyte clones from the joint of ReA patients exhibit different cytokine expression profiles refelecting their different roles in pathogenesis.
