Cytomegalovirus retinitis in a patient with rheumatoid arthritis being treated with combination immunosuppressive therapy

The clinical features and mortality risk factors of cytomegalovirus infection in patients with systemic lupus erythematosus

BACKGROUND

The clinical features and outcomes of cytomegalovirus (CMV) diseases in patients with systemic lupus erythematosus (SLE) are unknown. We analyzed such data from a medical center in Taiwan.

METHODS

We retrospectively reviewed the medical records of patients with SLE who were diagnosed with CMV diseases between 2006 and 2016 in Taipei Veterans General Hospital Taiwan. Clinical and laboratory parameters and treatment outcomes were analyzed.

RESULTS

The study enrolled 56 eligible patients with CMV diseases and separated them into survival (n = 24) and mortality (n = 32) groups. All cases showed a significantly high incidence of pneumonitis (71.43%). The patients in the mortality group had a higher SLE disease activity index (SLEDAI)-2000 (p = 0.009), more cases of recent methylprednisolone pulse therapy (p = 0.013) and pancytopenia (p = 0.001), stronger evidence of CMV infection demonstrated by polymerase chain reaction (PCR) in blood (p < 0.001) and bronchoalveolar lavage (p = 0.021), and more concurrent infections (bacteremia p = 0.026; fungemia p < 0.001).

CONCLUSIONS

Recent pulse therapy, pancytopenia, and concurrent infections constituted risk factors for mortality in patients with SLE and CMV infection. Among mortality patients, PCR rather than serological tests (IgM antibodies) helped to arrive at an earlier diagnosis.

Virus-Induced Anterior Uveitis (VIAU) in Immunocompromised Patients

PURPOSE

To describe the clinical characteristics, diagnosis, and treatment of VIAU in immunocompromised patients.

METHODS

A critical review of literature was performed.

RESULTS

Diagnosis and treatment of VIAU in immunocompromised patients may be a challenge due to atypical clinical-courses, severe presentations, and more frequent recurrences. A conclusive diagnosis can be made by aqueous-humour PCR-analysis. Visual prognosis depends on early diagnosis and prompt treatment. Frequent ocular examinations are recommended in HIV patients with CD-4-counts below 100 in order to rule out opportunistic ocular coinfections. It is essential to bear in mind the potential side-effects of therapeutic interventions and consider the possibility of Immune Recovery Uveitis (IRU) in eyes with treated viral retinitis after the initiation of HAART.

CONCLUSIONS

Early diagnosis and treatment of VIAU in immunocompromised patients can be achieved with high suspicion, recognizing clinical features, and obtaining specimens for molecular diagnostic testing in order to avoid usually severe ocular morbidity.

Cytomegalovirus Pneumonia in Patients with Rheumatic Diseases After Immunosuppressive Therapy: A Single Center Study in China

Background:

Rheumatic diseases involve multiple organs that are affected by immunological mechanisms. Treatment with corticosteroids and immunosuppressive agents may also increase the frequency of infection. Cytomegalovirus (CMV) is a widespread herpes virus and a well-recognized pathogen, which causes an opportunistic and potentially fatal infection in immunocompromised patients. This retrospective study aimed to investigate the clinical and laboratory characteristics of CMV pneumonia in patients with rheumatic diseases after immunosuppressive therapy in a single center in Shanghai, China.

Methods:

Eight hundred and thirty-four patients with rheumatic diseases who had undergone CMV-DNA viral load tests were included, and the medical records of 142 patients who were positive for CMV-DNA in plasma samples were evaluated. GraphPad Prism version 5.013 (San Diego, CA, USA) was used to conduct statistical analysis. The correlation between CMV-DNA viral loads and lymphocyte counts was assessed using the Spearman rank correlation coefficient test. Significance between qualitative data was analyzed using Pearson's Chi-squared test. The cut-off thresholds for CMV-DNA viral load and lymphocyte count were determined by receiver operating characteristic (ROC) curve analysis.

Results:

One hundred and forty-two patients had positive CMV viral load tests. Of these 142 patients, 73 patients with CMV pneumonia were regarded as symptomatic, and the other 69 were asymptomatic. The symptomatic group received higher doses of prednisolone (PSL) and more frequently immunosuppressants than the asymptomatic group (P < 0.01). The symptomatic group had lower lymphocyte counts, especially CD⁴⁺ T-cells, than the asymptomatic group (P < 0.01). By ROC curve analysis, when CD⁴⁺ T-cell count was <0.39 × 10⁹/L, patients with rheumatic diseases were at high risk for symptomatic CMV infection. The CMV-DNA load was significantly higher in the symptomatic patients than that in asymptomatic patients (P < 0.01; threshold viral loads: 1.75 × 10⁴ copies/ml). Seven patients had a fatal outcome, and they had lower peripheral lymphocyte counts (P < 0.01), including CD4⁺ and CD⁸⁺ T-cells (P < 0.01).

Conclusions:

When CD⁴⁺ T-cell count is <0.39 × 10⁹/L, patients are at high risk for pulmonary CMV infection. Patients are prone to be symptomatic with CMV-DNA load >1.75 × 10⁴ copies/ml. Lymphopenia (especially CD⁴⁺ T-cells), presence of symptoms, and other infections, especially fungal infection, are significant risk factors for poor outcome, and a higher PSL dosage combined with immunosuppressants may predict CMV pneumonia.

Cytomegalovirus infection causes morbidity and mortality in patients with autoimmune diseases, particularly systemic lupus: in a Chinese population in Taiwan

To investigate the clinical outcome of cytomegalovirus (CMV) infection in febrile hospitalized patients with autoimmune diseases, mostly systemic lupus erythematosus (SLE). Fifty-four febrile patients were analyzed retrospectively. Half were diagnosed as CMV infection, by positive CMV pp65 antigenemia assay. Clinical and laboratory data between two groups were compared. Correlation between laboratory data and SELENA-SLEDAI scores/mortality were analyzed in the CMV infection group. Receiver operating characteristic analysis was performed to determine the cutoff points of different parameters for predicting mortality or morbidity. The CMV infection group received a higher corticosteroid dosage (mean 26.3 mg/day) and a higher percentage of azathioprine use before admission than the non-CMV infection group. In the former, the deceased subgroup had a significantly higher number of infected leukocytes for CMV (shortened as CMV counts, P = 0.013), more cases of bacterial infection (P = 0.090), and a higher SLE disease activity index score (P = 0.072) than the alive subgroup. The CMV infection group had lower lymphocyte count and more positive bacterial infection than the non-CMV infection group did (P = 0.013 and P = 0.027, respectively). A level of 25 CMV particles/5 × 10(5) polymorphonuclear neutrophils (PMN) was the best cutoff point for predicting CMV-associated mortality, with a sensitivity of 75.0% and specificity of 72.2%. Moderate dose (30 mg/day) of prednisolone or azathioprine use predisposes patients with autoimmune diseases to CMV infection with concurrent bacterial infection. In particular, peak CMV counts at 25/5 × 10(5) PMN or low lymphocyte counts predict mortality or morbidity, respectively.

Clinical characteristics of cytomegalovirus infection in rheumatic diseases: multicentre survey in a large patient population

OBJECTIVE

To survey and elucidate the clinical characteristics of CMV infection in rheumatic disease patients.

METHODS

A detailed questionnaire survey on CMV infection was carried out against rheumatic disease patients hospitalized in member hospitals, and the obtained clinical and/or laboratory data were analysed.

RESULTS

Out of 7377 patients, 151 were diagnosed as having CMV infection. The underlying diseases ranged broadly, but SLE, microscopic polyangiitis, and dermatomyositis were the most common. Four were diagnosed histopathologically, and the others via positive CMV antigenaemia. In addition to oral corticosteroid for all but one patient, 81 were treated with pulsed methylprednisolone (MPSL), 64 with cyclophosphamide (CYC) and 36 with other immunosuppressants. Forty-four had a fatal outcome, for which presence of clinical symptoms, other infectious complications, lymphopenia, an older age (>59.3 yrs) and the use of pulsed MPSL were significant risk factors (P < 0.05) by univariate analysis. Multivariate analysis retained the first three (P < 0.05). The CMV antigenaemia count was significantly higher for the symptomatic than asymptomatic [10.1 (0.0-2998.0) vs 4.0 (1.3-1144.4)/10(5) PMNs, respectively, P < 0.05; threshold count: 5.6/10(5) PMNs]. No treatment benefit by anti-viral agent was observed as for survival.

CONCLUSION

CMV infection was mostly diagnosed by antigenaemia, and occurred among patients under strong immunosuppressive therapy using pulsed MPSL and/or immunosuppressants. Lymphopenia, presence of symptoms and other infections are significant risk factors for a poor outcome and pulsed MPSL and an older age may predict it. Patients were prone to be symptomatic with anti-genaemia count over 5.6/10(5) PMNs.

Cytomegalovirus retinitis in a patient with dermatomyositis

Cytomegalovirus (CMV) retinitis rarely occurs in patients with connective tissue disease. We present a rare case of CMV retinitis in a patient with dermatomyositis. A 38-year-old man was admitted due to blurred vision and floaters of right eye. He had been diagnosed with dermatomyositis and taken prednisolone and immunosuppressive agents for 10 months. He was diagnosed as having CMV retinitis based upon ophthalmologic examination, decreased CD4+T cell count, and positive IgM anti-CMV antibody. Intravenous ganciclovir was administrated with cessation of immunosuppressive agents for 40 days and the lesion did not progress. This is the first report of a CMV retinitis that developed in a patient with dermatomyositis.

Cytomegalovirus retinitis in Wegener's granulomatosis: case report and review of the literature

PURPOSE

To present the first case of cytomegalovirus (CMV) retinitis in a Wegener's granulomatosis patient on systemic cyclosporine A (CsA) therapy.

METHODS

A 41-year-old patient was treated with systemic CsA for c-ANCA positive Wegener's granulomatosis. Four weeks later he presented with blurred vision and a retinitis was diagnosed in the right eye. After detection of CMV DNA by polymerase chain reaction (PCR), the patient was treated with intravenous gancyclovir. Due to bone marrow toxicity, systemic antiviral therapy was discontinued and an intravitreal gancyclovir pellet was implanted.

RESULTS

The retinitis lesions were scarified under this therapy and the patient's visual function was restored completely.

CONCLUSIONS

Cytomegalovirus retinitis can occur under systemic monotherapy with CsA in patients with systemic vasculitis. Intraocular virus DNA detection by PCR is recommended to rule out retinal involvement of the underlying vasculitis in atypical cases and to preserve the patient's visual acuity.

Bilateral cytomegalovirus retinitis in a patient with systemic lupus erythematosus and end-stage renal disease

Rheumatic diseases are not commonly associated with cytomegalovirus (CMV) retinitis. We report a case of bilateral CMV retinitis in a human immunodeficiency virus-seronegative patient with systemic lupus erythematosus (SLE) who was undergoing hemodialysis for end-stage renal disease. The CMV retinitis in this patient was associated with combined azathioprine and low-dose corticosteroid therapy for lupus flare. This association may have important clinical implications because this drug combination is used routinely to treat active SLE. Our patient responded to discontinuation of azathioprine, reduction of the corticosteroid dose, and systemic administration of ganciclovir. We recommend that clinicians maintain heightened awareness of the possibility of CMV retinitis in patients with SLE and end-stage renal disease who are receiving azathioprine and low-dose corticosteroids.

Cytomegalovirus infection in a patient with rheumatoid arthritis

Background. - Pulmonary dysfunction in rheumatoid arthritis (RA) patients treated with low-dose methotrexate is usually caused by bacterial infection and less frequently by an immunoallergic reaction to the drug (acute hypersensitivity pneumonitis). Opportunistic infections are a rare cause. We report a case of cytomegalovirus pneumonia during bone marrow aplasia in a patient with RA taking methotrexate and cyclosporine.Conclusions. - Cytomegalovirus infection is a rarely reported cause of pulmonary dysfunction. This diagnosis should be considered in immunocompromised RA patients with no other satisfactory explanation for pulmonary dysfunction.
