[The presentation of viral hepatitis C infection without cryoglobulinemia with a peripheral neuropathy. Five case reports].

INTRODUCTION: Peripheral neuropathies are the most common neurological complication of viral hepatitis C infection with mixed cryoglobulinemia. CASES REPORT: We report five cases (three men, two women) of peripheral neuropathies revealing viral hepatitis C infection without cryoglobulinemia; the patients' mean age was 56 years. Paresthesias were the most frequent symptom. Electroneuromyographic examination found one case of polyneuropathy and four cases of multiplex mononeuropathies; the complement level was normal in all patients and the rheumatoid factor positive in two cases. Etiological investigations for peripheral neuropathy remained negative. Treatment and outcome were variable. DISCUSSION: Negative cryoglobulinemia in cases of VHC infection with neurological features has been described in the last few years, suggesting the possibility of other mechanisms such as direct action of the virus on the nervous system. There is no consensus on the treatment and outcome is variable. CONCLUSION: Peripheral neuropathy may reveal VHC infection, underscoring the need for VHC serology testing in etiological investigations for peripheral neuropathies.

[Reccurent stroke revealing catastrophic antiphospholipid syndrome with hepatitis C viral infection].

INTRODUCTION: Very little cases of antiphospholipid syndrome (APLS) have been described among patients having chronic hepatitis C virus infection (HCV). CASE REPORT: We report the observation of a 43-year-old woman who presented APLS diagnosed following recurrent strokes. Etiological investigations concluded on an association of APLS with HCV infection. DISCUSSION: Besides being exceptional, this association raises certain etiopathogenic problems. Indeed while antiphospholipid antibodies (aPL) are frequently noted during chronic hepatitis C, they rarely generate thromboembolic complications.

[Devic's neuromyelitis optica in Morocco. A study of 9-cases].

INTRODUCTION: Optic neuromyelitis or Devic's syndrome associates optic neuritis and myelitis. It can have a monophasic or relapsing course. The limits of this entity remain controversial. METHODS: We analyzed the results of a retrospective series of Moroccan patients with Devic's syndrome defined on the basis of Wingerchuk's criteria. RESULTS: Six women and three men were retained for study; average age was 39 years. Three patients presented with a monophasic form and six with relapsing disease. CSF analysis was abnormal in five. Brain MRI was normal in eight. Signal abnormalities extended over more than three vertebrae in eight patients. Infections were associated with neurological features in half of the patients. DISCUSSION: Our results are in agreement with those of large series in the literature regarding the clinical, imaging, and laboratory findings and disease course. We also noted that infections were more frequently associated with Devic's syndrome in our patients. CONCLUSION: Our study reports the results of the first North African series of Devic's syndrome patients. We suggest that this syndrome is particular in our context due to the high frequency and diversity of associated infections.

[Aseptic meningoencephalitis in primary Gougerot-Sjögren's syndrome].

INTRODUCTION: Central nervous system involvement is rarely observed in primary Sjogren's syndrome (PSS) and aseptic meningoencephalitis occurs exceptionally. OBSERVATION: We report the case of a 25-year-old woman who presented with weakness of the four limbs, vision loss and concentration deficit. Neurological examination revealed a mental confusion, cerebellar involvement and spastic tetra paresis. Cerebrospinal fluid analysis revealed elevation of cell counts (162/mm3) and protein content (3 g/l). MRI showed increased T2 signals in the white matter. No evidence for an infectious etiology, especially tuberculosis, was obtained in this patient. PSS was diagnosed on the basis of ocular dryness, lachrymal hyposecretion, aspects of labial gland biopsy witch revealed destruction of the ducts with periductal lymphocytic infiltration and positive anti-SSB antibodies. Oral corticosteroids (1 mg/kg/day) allowed an improvement of the neurological manifestations. CONCLUSION: Aseptic meningoencephalitis can be the first manifestation of primary Sjogren's syndrome. Infectious causes, particularly tuberculosis which is frequent in our context must be ruled out.

[Devic's optic neuromyelitis and pulmonary tuberculosis].

INTRODUCTION: Optic neuromyelitis or Devic's syndrome is a very rare disease affecting the optic tracts and the spinal cord. Its association with evolving pulmonary tuberculosis has been noted in a handful of case reports. CASE REPORT: The authors reportthe case of a 40 year old patient with evolving pulmonary tuberculosis who experienced bilateral blindness followed by paraplegia and sphincter disturbance. Clinical examination and investigations excluded direct tuberculous involvement of the nervous system or a reaction to antituberculous therapy and Devic's syndrome was diagnosed, based on Wingerchurk's criteria. Following treatment with corticosteroids and antituberculous chemotherapy, the patient recovered normal mobility and sphincter control but remained completely blind. CONCLUSIONS: Throughout this case report, the authors emphasise the rarity of this association and discuss the pathophysiological mechanism, which appears to be an immune dysfunction triggered by mycobacterial infection.
