CRAZY CAT LADY SYNDROME TOXOPLASMOSIS
Toxoplasmosis
Toxoplasmosis � parasitic disease caused by the
protozoan Toxoplasma gondii � T gondii infects a large proportion of the
world's population (perhaps one third) but uncommonly causes clinically significant disease
� Acute toxoplasmosis is asymptomatic in 80-90% of healthy hosts
Acute toxoplasmosis in hosts who do not have AIDS but are immunodeficient � CNS toxoplasmosis occurs in 50% of patients � Ocular toxoplasmosis � Signs and symptoms similar to those observed
in immunocompetent hosts- flulike symptoms and lymphadenopathy
� Myocarditis � Toxoplasmic pneumonitis - Typical symptoms
of a pulmonary infection, mirroring in particular P (carinii) jiroveci, including nonproductive cough, dyspnea, chest discomfort, and fever
CNS TOXOPLASMOSIS 3 major pathologic pattern � Diffuse encephalopathy with or without
seizure � Single or large progressive mass lesion � Meningoencephalitis
Remington J , Desmonts G . Toxoplasmosis . In: Remington JS , Klein JO editor. Infectious Diseases of the Fetus and Newborn Infant . 3rd ed.. Philadelphia, Pa: WB Saunders Co; 1990;p. 89–95
Procedures for diagnosis � Lumbar puncture � Brain biopsy � Lymph node biopsy � Amniocentesis - Perform amniocentesis at
20-24 weeks' gestation if congenital disease is suggested
� Bronchoalveolar lavage
Immunology � Anti-Toxoplasma immunoglobulin G (IgG)
titers present a 4-fold increase that peak 6-8 weeks following infection and then decline over the next 2 years, although they remain detectable for life.
� Anti-Toxoplasma IgM appears in the first week of the infection and then declines in the next few months
Murat H,Toxoplasmosis, http://emedicine.medscape.com/article/229969-workup#a0756
Association of antibodies to T.Gondii with SLE � The toxoplasma serological status of 50
patients with SLE was compared with that of 50 healthy controls; high titres of toxoplasma antibody were significantly more common in the patients with SLE. These titres did not correlate with any of the routinely measured indices in SLE nor with the patients' prior treatment
MH wilcox, R J Powel, et., Toxoplasmosis and SLE ,Ann Rheum Dis. Apr 1990; 49(4): 254–257.
Imaging � MRI has superior sensitivity to CT scanning,
and often demonstrate a single or multiple lesion(s) or more extensive disease not apparent on CT scans.
� One study showed that MRI detected abnormalities in 40% of patients whose abnormalities were not detected on CT.

Imaging � Joseph et al reported that 35% of
computed tomography (CT) brain scans were abnormal and 65% of magnetic resonance (MR) scans, but CT scanning remains valuable in identifying hemorrhages and larger infarcts in patients with systemic lupus erythematosus

Cerebral toxoplasmosis in SLE Case reports
� There have been many reports of toxoplasmosis in SLE patients, mimicking SLE manifestations , and they emphasized the diagnostic problems and recommended serologic analysis for toxoplasmosis before initiation of and during treatment with corticosteroids (2-5)
� Zamir et al diagnosed toxoplasmosis infection from a post mortem findings of a patient mimicking lupus cerebritis. CT brain was normal
� Feinglass et al detected CSF abnormalities consistent with Toxoplasmosis infection in 32% of 37 patients with NPSLE

Case reports � Seta et al reported a case of
toxoplasmosis in SLE patient who was in low disease activity, with high CD4 ratio
� ? Relationship with HIV patients on HAART with Immune Reconstruction Inflammatory Syndrome(IRIS)

? Possible mechanism � Normalization of immunity in patients who
have inactive SLE and are receiving relatively low doses of steroids and/or immunosuppressants may contribute to the manifestation of opportunistic infections, as the immune system of SLE patients may originally show hyper‐responsiveness to non‐self as well as self‐antigens

Role of prophylaxis? � Opportunistic infections – rare, ?
underreported � Lack of literature � No guidelines exist � ? Implementing guidelines from
preventing OI in HIV or bone marrow transplanted patients
Perspectives on prevention of OI in SLE patients � Yearly influenza shot � Pneumococcal vaccination � Regular pap smears � TB skin test prior to immunosuppressive � HBAg, HCV, HIV serology baseline � Strongyloides screening in endemic areas

Back to case…..
SLE with CNS toxoplasmosis mimicking NPSLE
SLE � Pancytopenia � ANA � Hypocomplementamia � Mucocutaneous
CNS Toxoplasmosis � Imaging � Immunology � Responded to
toxoplasmosis treatment
Conclusion � Cerebral lupus is a diagnostic challenge � Essential TRO CNS infections prior to
administration of immunosuppressant � Toxoplasmosis presentations are
nonspecific and may be considered if NPSLE symptoms does not abate with standard immunosuppressive therapy
Conclusions � Further study is warranted before routinely
recommending prophylaxis for all SLE patients on steroid therapy.
� In patients receiving combination steroid and cytotoxic therapies such as cyclophosphomide, prophylaxis with trimethoprim-sulfamethoxazole should be considered
