Cultivation of a mycoplasma from the bone marrow in systemic lupus erythematosus disseminatus

Rare complicated parapneumonic effusion, Mycoplasma pneumoniae with new-onset lupus flare: Case report and literature review

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia–related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain. He was found to have right-side loculated complicated parapneumonic effusion and underwent drainage with a pleural catheter followed by fibrinolytic therapy. He was then found to have new-onset systemic lupus erythematosus concomitant with Mycoplasma pneumonia, leading to lupus flare and lupus nephritis. He responded well to levofloxacin, steroids, hydroxychloroquine, and mycophenolate, with complete resolution of loculated pleural effusion and symptom improvement. Our case describes the rare combination of Mycoplasma pneumoniae pneumonia, parapneumonic pleural effusion, and lupus flare with lupus nephritis. Early identification and treatment can lead to better out come in young patients.

Genital Mycoplasma infection among Mexican women with systemic lupus erythematosus

OBJECTIVE

To assess the prevalence of genital Mycoplasma spp. among women with systemic lupus erythematosus (SLE) and to identify factors associated with such infection.

METHODS

A cross-sectional study was conducted among patients with SLE and healthy women who attended a hospital in Puebla, Mexico, between July 29, 2014, and January 4, 2015. All participants were aged 18 years or older and sexually active. A structured interview assessed sociodemographic, obstetric, gynecologic, and clinical characteristics. Disease activity was evaluated using the Mexican SLE Disease Activity Index. Polymerase chain reaction was used to detect the presence of Mycoplasma spp. in genital samples.

RESULTS

Ureaplasma urealyticum was the only genital mycoplasma detected; it was present in 32 (24.6%) of 130 patients with SLE and 12 (12.8%) of 94 healthy women. Patients with SLE had increased odds of infection (odds ratio 2.120, 95% confidence interval 1.046-4.296). Among patients with SLE, multiparity was more common in those with U. urealyticum infection (P=0.043).

CONCLUSION

One-quarter of women with SLE had genital infection with U. urealyticum. An association was found between infection and multiparity among women with SLE.

Ureaplasma urealyticum and Mycoplasma hominis in women with systemic lupus erythematosus

OBJECTIVE

To determine the prevalence of genitourinary mycoplasma infection in women with systemic lupus erythematosus (SLE).

METHODS

Urine specimens from 49 patients with SLE and 22 patients with chronic fatigue syndrome (CFS) were cultured for mycoplasma. Patient records were reviewed for medical history and SLE disease activity.

RESULTS

Sixty-three percent of the SLE patients were culture positive, compared with 4.5% of the CFS patients (P less than 0.001). Neither corticosteroid treatment, SLE activity, nor age accounted for this difference.

CONCLUSION

Genitourinary mycoplasma colonization occurs significantly more frequently in SLE than in CFS.
