Clinical features of patients with Rhupus syndrome / 北京大学学报(医学版)

OBJECTIVE@#To investigate the clinical and serological features of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) overlap syndrome (Rhupus syndrome).@*METHODS@#We retrospectively reviewed the medical records of 21 patients with Rhupus syndrome who were hospitalized at Department of Rheumatology and Immunology, People's Hospital of Xinjiang Uygur Autonomous Region between January 2010 and January 2018. We compared the joint involvement, autoantibodies and clinical manifestations of Rhupus syndrome with 81 cases of RA-alone and 51 cases of SLE-alone.@*RESULTS@#In 21 patients with Rhupus syndrome, there are 3 males and 18 females. Compared with the SLE-alone group, the patients with Rhupus syndrome were older [(49.43±11.66) vs. (40.59±12.73), P=0.008]. The median age of the patients with Rhupus syndrome at RA onset was significantly younger than that of the RA-alone patients [(32.58±11.14) vs. (43.11±11.83), P=0.010]. Of the 21 patients with Rhupus syndrome, the initial diagnosis was RA in 57% (12/21), except 2 male patients, the other 10 patients with SLE manifestations were menopause, the mean age of amenorrhea or menopause was (44.30±5.33) (36-50) years. The mean interval between the onset of SLE and RA was 10.83 years. Two patients started with SLE manifestations. Moreover, both diseases simultaneously developed in 33.3% of the patients. Except one male patient, 3 patients were in menopause stage when RA and SLE appeared. The positive rate of specific antibody Rhupus syndrome was similar to that of RA. Renal damage was relatively rare in SLE related manifestations, but the incidence of interstitial lung disease was higher. There were no significant differences in the prevalence of complements C3 and C4, antinuclear antibody (ANA), anti-double-stranded DNA (anti-dsDNA), anti-SSA or anti-SSB antibody between the Rhupus syndrome and SLE-alone group.@*CONCLUSION@#Rhupus syndrome is an overlapping syndrome in which RA and SLE coexist. Most of the diseases occur in RA and the related manifestations of RA are more serious than those of SLE. The incidence of Rhupus syndrome may be related to the change of sex hormone levels.

Síndrome de Rhupus. Superposición infrecuente / Rhupus syndrome. Uncommon overlap

Se presenta el caso de una mujer joven, con antecedente de 3 meses de astenia, acompañada de rigidez y dolor en articulaciones pequeñas y grandes, además lesiones rojo violáceas, pruriginosas, confluentes, no dolorosas, generalizadas, en las últimas 2 semanas previas a su consulta, sangrado de encías y epistaxis. En hemograma trombocitopenia y leucopenia. Punción aspiración de medula ósea compatible con purpura trombocitopénica inmunitaria. Marcadores de Lupus eritematoso y artritis reumatoide positivos

Rhupus syndrome. A rare combination / Síndrome de Rhupus. Una superposición infrecuente

Abstract Rhupus syndrome is a rare combination of rheumatoid arthritis and systemic lupus erythematosus, and is characterized by the presence of erosive arthritis together with symptoms and signs of systemic lupus erythematosus. Among its complications, is the presence of rheumatoid nodules, and neurological and renal involvement that further complicates its prognosis, thus significantly reducing the perception of health-related quality of life in patients who suffer from it. The case is presented of a female patient diagnosed with lupus erythematosus, who during the course of the disease, developed clinical and humoral signs that led to the diagnosis of syndrome Rhupus syndrome. This is believed to of relevance to the knowledge of the medical community.

Resumen El síndrome de Rhupus es una rara superposición de artritis reumatoide y lupus eritematoso sistémico, que se caracteriza por la presencia de una poliartritis erosiva asociada a síntomas y signos de lupus eritematoso sistémico. Entre sus complicaciones destaca la presencia de nódulos reumatoideos, afectación neurológica y renal que complican más aún la evolución del caso, disminuyendo considerablemente la percepción de la calidad de vida relacionada con la salud de los pacientes que lo padecen. Se presenta el caso de una paciente mujer con diagnóstico de lupus eritematoso, que desarrolla en el curso de la enfermedad manifestaciones clínicas y humorales que permiten llegar al diagnóstico de un síndrome de Rhupus, lo cual consideramos sea de importancia para el conocimiento de la comunidad médica.

Clinical Manifestations of Rheumatoid Arthritis and Concurrent Systemic Lupus Erythematosus / 医学研究杂志

Objective To investigate the clinical manifestations of coexistent rheumatoid arthritis(RA)and systemic lupus erythematosus(SLE)(Rhupus syndrome).Methods Clinical data from a patient with Rhupus syndrome were analyzed combined with literature review.Results The patient was a middle-aged female,who presented with features of RA and developed features of SLE 7 years later.Renal involvement in common cases is rare but presented in our patient with severe renal dysfunction.The patient showed part remission with glucocorticosteroids and cyclophosphamide therapy.Conclusion Rhupus syndrome is a rare condition sharing features of RA and SLE.These patients present with features of one disease but later on develop features of another.Glucocorticosteroids and immune suppressors are effective.Appreciation of these patients with rhupus is important since their therapy and outcome differ from those having RA or SLE alone.

A Case of Rhupus Syndrome with Lupus Enteritis / 대한류마티스학회지

Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are common rheumatologic diseases, and considered to be separate diseases with defined criteria for diagnosis. Occasionally, patients with overlapping features of RA and SLE, termed "rhupus syndrome", have been encountered. Appreciation of these patients with rhupus is important since their therapy and outcome differ from those having RA or SLE alone. Rhupus syndrome is a systemic disease which can involve gastrointestinal tract as SLE alone. Lupus enteritis, most feared gastrointestinal complication of SLE, can develop in rhupus syndrome, Recently, we experienced a 54-year-old female patient with lupus enteritis during treatment of rhupus syndrome and present the case here with brief review of literatures.

'Rhupus syndrome', Coexistence of Rheumatoid Arthritis and Systemic Lupus Erythematosus / 대한류마티스학회지

OBJECTIVE: This study was designed to evaluate clinical features of 20 patients with rhupus syndrome and compare its characteristics with systemic lupus erythematosus(SLE) and rheumatoid artiritis(RA). METHODS: Patients considered to have rhupus who met the American College of Rheumatology(ACR) 1997 and 1987 revised criteria for SLE and RA, respectively and age, sex, and disease duration matched 64 patients with RA and 56 patients with SLE were selected for comparison. RESULTS: Twenty patients were all female and their mean age was 43.7+/-9.6 years(range 25~68). They had 5.5 ACR criteria for RA and 5 criteria for SLE. The mean age at onset of RA was 35.2+/-10.5 years(19~63) and that of SLE was 38.2+/-10.0 years(20~63), giving a mean interval between the diagnoses of the two diseases of 3.0+/-5.7 years (14~(-6)). There were 2 patients(10%) with rheumatoid nodule, and 18 patients(90%) with rheumatoid factor, and 16 patients(80%) with bone erosions on hand or wrist joints. The criterial for SLE included malar rash(20%), discoid rash(0%), photosensitivity(30%), oral ulcer(45%), arthritis(100%), serositis(35%), renal disorder(15%), neurologic disorder(0%), hematologic disorder(100%), immunologic disorder(90%), and positive antinuclear antibody(100%). Anti-dsDNA was more than 7.0U/ml in 15 patients(75%). The patients with rhupus syndrome showed lower amount of 24 hour urine protein, more severe radiologic involvement, younger age at onset of arthritis, higher titer of rheumatoid factor, lower frequency of low C3, and less complicated clinical course when compared with the patients with SLE(p<0.05). More frequent anemia, Rayanud's phenomenon, and more complicated clinical course in rhupus when compared with the patientw with RA(p<0.05), but the radiologic stage of hand and wrist was similar between rhupus and RA. CONCLUSION: Rupus syndrome showed somethisg different clinical characteristics and clinical course when compared with SLE and RA.
