Infection disséminée au virus varicelle-zona avec gastrite hémorragique compliquant une leucémie lymphoïde chronique : une observation et revue de la littérature

Introduction

The reactivation of varicella-zoster virus occurs in immunocompromised patients, especially in cases of hematological malignancy. Disseminated reactivation could involve digestive tract with life-threatening condition.

Case report

A 76-year-old woman, with a history of chronic lymphocytic leukemia, presented with left hypochondrium pain, and a vesicular rash with hemorrhagic shock that revealed an hemorrhagic gastritis due to varicella-zoster virus. The literature review identified 28 additional cases of gastrointestinal mucosal damage during reactivation of varicella-zoster virus. Mortality is 40%. We report here the first case in the course of low-grade lymphoid malignancy.

Conclusion

Acute gastrointestinal symptoms in immunocompromised patients should evoke a varicella-zoster virus reactivation with gastrointestinal involvement. This clinical manifestation, although rare, should not be ignored because of its severity.     

Maladie de Lyme avec hépatite et corticothérapie : à propos d’une observation

Introduction

Abnormalities of liver function tests have been occasionally described in large series of Lyme disease, but only one case of hepatitis directly related to infection have been described in literature.

Case report

A 78-year-old-man, with a past medical history of polymyalgia rheumatica (PMR) who had discontinued corticosteroids two years before, presented a transient acute fever and liver cholestasis and cytolysis after an exposure to tick bites. A few days later, cervical pain occurred and corticosteroids were resumed as a PMR relapse was suspected. Hematogenous dissemination with acute meningoradiculitis and multiple erythema migrans led to conclude to a stage 2 Lyme disease.

Conclusion

Although hepatitis complicating the course of Lyme disease has been described in literature, the marked inflammation in our patient led us to investigate the possibility of a co-infection. Also, we discuss the responsibility of corticosteroids in clinical worsening of Lyme disease if they are prescribed without concomitant antibiotics.     

Hépatite E aiguë associée à un syndrome de Guillain-Barré chez un patient immunocompétent

Introduction

Hepatitis E virus (HEV) infection is now recognized to be an emerging autochthonous disease in several countries. There have been several reports of neurological manifestations associated with HEV infections. Immunocompromised patients seem to be particularly vulnerable.

Case report

We report a 73-year-old man who presented with an acute polyradiculopathy and an acute hepatitis. HEV RNA was positive in serum and cerebrospinal fluid. Serum antiganglioside antibodies were also detected. Liver function tests returned to normal rapidly and HEV RNA was undetectable 4 weeks after initial testing. The neurological features improved gradually with the use of intravenous immunoglobulins.

Conclusion

We report a case of Guillain-Barré syndrome related to acute hepatitis E in an immunocompetent patient. The outcome was favorable after intravenous immunoglobulins administration. HEV screening should be systematic in patients who present with an acute polyradiculopathy and abnormal liver function tests.     

Interactions entre les virus de l’immunodéficience humaine et de l’hépatite C

Introduction. — Prevalence of hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected subjects is around 9%, varying according to the mode of contamination. Reciprocal interactions between the two viruses have to be evaluated.Current knowledge and key points. — HCV infection is usually associated with chronic hepatitis and detectable viremia in HIV-infected Patients. HIV infection enhances HCV replication, leading to more severe liver lesions and to a more rapid occurrence of cirrhosis. This underlines the need for both early diagnosis and therapy in order to avoid severe evolution of the liver disease.Future prospects and projects. — Even though the rate of long-term responses to interferon α is low, improvement may be expected from combined therapies, especially with combination including ribavirin. The impact of both antiretroviral triple therapy and accompanying immune restoration on natural history and treatment of HCV infection has to be assessed, as the above mentioned consensual conclusions may be modified in a near future.     

Réactivation d’une tuberculose sous bithérapie interféron-pégylé et ribavirine pour une hépatite chronique C

Hepatitis C viral infection can be associated with other infectious diseases including viral and bacterial infections such as tuberculosis. Mycobacterium tuberculosis infection may be latent for many years and revealed during an immunodeficiency state. The responsibility of antiviral treatment in the reactivation of tuberculosis is controversial. We report two cases of tuberculous reactivation during bitherapy with pegylated interferon and ribavirin for chronic hepatitis C. A rapid viral response was obtained in both cases. Tuberculous reactivation occurred at 12 and 13 weeks of antiviral treatment, respectively. Tuberculosis involved urinary tract in one patient and lymph nodes in the other. Antituberculous treatment was given and antiviral treatment maintained. The outcome of tuberculosis was favourable and a sustained viral response was obtained for both patients.     

Hépatite aiguë médicamenteuse à l’anakinra chez une patiente traitée pour une maladie de Still de l’adulte

Introduction

Adult-onset Still's disease is characterized by non-specific polymorphic features. The efficacy of anakinra, an IL-1 receptor antagonist, has been shown in several studies. This medication is well-tolerated, and only one case of severe hepatitis has been previously reported.

Case report

A 22-year-old woman presented with fever, rash, arthritis, and pericarditis, associated with systemic inflammatory response syndrome and elevated ferritin serum level with low glycosylated ferritin. Adult-onset Still's disease was diagnosed, but treatment with steroids did not achieve remission. The patient was then treated with anakinra, which resulted in spectacular improvement, but 3 weeks after the initiation of the treatment she experienced severe hepatitis that resolved after the discontinuation of anakinra.

Conclusion

Hepatitis is a rare side effect of anakinra and the monitoring of liver tests should be recommended during anakinra therapy.     

Thrombopénie par transformation gélatineuse de la moelle et hépatite aiguë de dénutrition chez une patiente anorexique mentale

Anorexia nervosa can be a life-threatening eating disorder when complicated with electrolyte disturbance, gelatinous transformation of the bone marrow or starvation induced acute hepatitis. We report a 43-year-old woman suffering from anorexia nervosa for more than 25 years, who was admitted in intensive care unit for a fluctuating level of consciousness related to starvation-induced acute hepatitis. Gelatinous transformation of the bone marrow was also diagnosed. Those two entities are rare and, to our knowledge, have not been previously reported jointly in anorexia nervosa.     

Rétinopathie dysorique à l’interféron au cours de l’hépatite chronique virale C. À propos d’un cas et revue de la littérature

Introduction

The ophthalmic complications following interferon therapy in chronic hepatitis C are rare. The most common adverse ophthalmic outcome is the dysoric retinopathy characterized by the presence at the fundus examination of cotton wool spots and retinal hemorrhages particularly around the optic disc.

Case report

A 63-year-old man presented to the hepatology department with a compensated cirrhosis C. His medical history was positive for hypertension controlled by medical treatment. A combined treatment with pegylated interferon α2a plus ribavirin was initiated. Three months later, the patient reported a sudden decreased vision in both eyes. Fundus examination revealed cotton wool spots with retinal hemorrhage. The diagnosis of dysoric retinopathy was established. The antiviral treatment was discontinued. One month later, the patient was asymptomatic and the ocular lesions have disappeared.

Conclusion

Dysoric retinopathy is a non-specific complication of interferon therapy in chronic hepatitis C. Despite its good prognosis, a careful fundus examination is required before and during the treatment especially for the patients with risk factors for this adverse event (advanced age, diabetes and high blood pressure).     

Polyglobulies : penser aux hémoglobines hyperaffines pour l’oxygène

Hemoglobin variant with high oxygen affinity is an uncommon, often misdiagnosed, etiology of erythrocytosis. We report two cases of erythrocytosis. Their hemoglobin–oxygen dissociation curve showed a P50 value (the oxygen tension at which hemoglobin is 50% saturated) below the normal range. Globin chains electrophoresis and DNA analysis evidenced hemoglobin Olympia and hemoglobin Malmö, respectively. More than 200 variants of hemoglobin with increased oxygen affinity have been described, that are in about one-third responsible of secondary erythocytosis because of tissular hypoxia. Such abnormal haemoglobin identification should be routinely included in the diagnostic work-up of unexplained erythocytosis, particularly in young people.     

Virus de l’hépatite B, manifestations extrahépatiques immunologiques et risque de réactivation virale

Hepatitis B virus (HBV) infection is frequent with about 400 million individuals infected worldwide. Extrahepatic manifestations may be observed in up to 20% of patients infected with HBV, in both acute and chronic infections. The best-described manifestations are polyarteritis nodosa and glomerulonephritis. Besides manifestations related to HBV, patients presenting with primary autoimmune disorders and infected with HBV may exhibit reactivation of hepatitis B during immunosuppressive therapy that may be life-threatening. This article focuses on autoimmune manifestations related to HBV and its treatment, and on the risk of reactivation of HBV hepatitis in patients with primary autoimmune disorders treated with immunosuppressive agents.     

Concentration plasmatique élevée de la vitamine B12 : un indicateur des maladies hépatiques ou tumorales

Purpose

To identify the diseases that are associated with a high plasma concentration of vitamin B12 and to measure the strength of this association.

Patients and methods

Retrospective study including all admissions between 1st May, 2005 and 30th April, 2008 in the UMAG pole departments (emergency, internal medicine, acute geriatrics and medical intensive care) with a test for plasma vitamin B12. The association between each of medical information system codes (solid tumors, malignant hematologic process, and renal disease) and a high or low vitamin B12 concentration was measured by odds ratios (OR) from logistic models taking into account repeated admissions, with adjustment for age and the weighted Charlson index.

Results

Among 3702 admissions, 12% had a B12 more than 820pg/ml, 10.4% a B12 less than 180 pg/ml and 77.6% a normal B12 concentration. After adjustment for age and the weighted Charlson index, high concentration of vitamin B12 was associated with interstitial renal diseases (OR 2.7; 95% CI: [1.7–4.2]), and cirrhosis or hepatitis (OR 4.3; [2.9–6.4]). After additional adjustment for these parameters, it was still associated with tumors (OR 1.8; [1.2–2.6]), malignant hematologic diseases (OR 2.1; [1.3–3.5]), metastasis (OR 2.9; [1.5–5.9]), liver metastasis (OR 6.2; [2.7–14.5]), liver carcinoma (LC) (OR 3.3; [1.1–10.4]), liver tumors other than LC (OR 4.7; [1.2–17.9]) and lymphoma (OR 3.2; [1.6–6.4]) but not with myeloma (OR 1.9; [0.6–1.4]). Low concentration of B12 was associated with myeloma (OR 2.9; [1.3–6.6]).

Conclusion

Finding a high plasma concentration of vitamin B12 should lead to a systematic search for a hepatic disease or a tumor, and particularly for a hepatic localization of a tumor.     

Porphyrie cutanée tardive familiale révélée par une hépatite C chronique. À propos d'un cas

The hepatitis C virus (VHC) is probably the main aetiological factor of severe liver damages associated with the sporadic variety of porphyria dutanea tarda (PCT) in a 28 year-old woman revealed by a chronic C virus infection. Treatment with interferon alpha was delivred.     

Étiologies et évolution des hépatites granulomateuses : étude rétrospective de 21 cas consécutifs

Purpose

To assess the etiologies and outcome of liver granulomatosis.

Methods

We analyzed all consecutive liver granulomatosis diagnosed in our internal medicine department from 2000 to 2008.

Results

Among 471 liver biopsies, 21 disclosed evidence of liver granulomatosis (4.5%), in sixteen women (76%) and five men, with a median age of 41 years. Thirteen were caucasians (62%). At the time of diagnosis, six (28.5%) had isolated abnormal liver function tests, and fifteen (71.4%) presented with clinical manifestations. The underlying cause was identified in 18 cases (85.7%). Eleven (52.3%) were systemic diseases: five (23.8%) primary biliary cirrhosis, two (9.5%) primary sclerosing cholangitis, two (9.5%) common variable immunodeficiency, one (4.7%) Sjögren's syndrome, and one (4.7%) Behçet's disease. Two (9.5%) patients had sarcoidosis. Three (14.3%) liver granulomatosis were of infectious origin (tuberculosis, schistosomiasis, and hepatitis C virus), two (9.5%) were neoplastic (Hodgkin's lymphoma and liver cell adenoma), and three (14.3%) were idiopathic. With a median of 38 months of follow-up, four patients (19%, two common variable immunodeficiency and two sarcoidosis) developed portal hypertension, independently of cirrhosis. One patient died of cryptococcosis.

Conclusion

In accordance with other European studies, systemic diseases are the main causes of hepatic granulomas. Liver granulomatosis related to common variable immunodeficiency and sarcoidosis are at risk of portal hypertension.     

Élévation modérée,persistante et inexpliquée des transaminases

Unexplained, subclinical chronically elevated transaminases is mainly a marker of non-alcoholic fatty liver disease, metabolic syndrome, alcoholism and diabetes, which are very common situations but viral hepatitis and iatrogenic origin must also be considered. Before looking for hepatic or genetic rare diseases, it is worth considering hypertransaminasemia as a clue for muscular disease, particularly in paediatric settings, and creatine phosphokinase is a specific marker. Then, patient history, examination and appropriate biologic requests can permit the identification of less frequent disorders where isolated hypertransaminasemia is possibly the unique marker of the disease for a long while: hemochromatosis, celiac disease, autoimmune hepatitis, Wilson's disease, α1-anti-trypsine deficiency, thyroid dysfunctions, Addison's disease. Liver biopsy should be performed only in patients with aspartate aminotransferases upper the normal range or alanine aminotransferases higher than twice the normal range after 6 months delay with dietetic corrections.
