Chilblain Lupus erythematosus: Report of 15 Cases

M.-S. Doutre; C. Beylot; J. Beylot; E. Pompougnac; P. Royer

In this retrospective study, the authors describe the clinical, histologic and laboratory features of 15 cases of chilblain or perniotic lupus. In winter, the patients (14 women, 1 man) develop chilblain-like lesions, chiefly in the toes (8 times) and fingers (11 times). Histologic features are identical to those of discoid lupus erythematosus. The damaged skin gives a positive fluorescent band test. Usually, these lesions occur in association with discoid lupus of the face. However, in 8 patients, they were the only cutaneous sign of lupus. This form of lupus can evolve to a systemic form, as was the case with 3 patients.

A case-control study was undertaken to determine risk factors for lactic acidosis in human immunodeficiency virus-infected patients treated with nucleoside reverse-transcriptase inhibitors (NRTIs). From May 1996 to June 2000, 9 patients with lactic acidosis (defined as a plasma lactic acid level of >5 mM and plasma pH of <7.38) were identified. Control patients were randomly selected from among a large cohort of patients who initiated a dual NRTI regimen in 1996 or after. Two factors were associated with an increased risk of lactic acidosis: first, a creatinine clearance of <70 mL/min before lactic acidosis (OR, 15.8 [range, 3.0-86.5], P<10(-4)), and, second, a low nadir CD4+ T lymphocyte count before the inception of NRTI therapy (OR, 8.4 [range, 1.2-infinity], P=.03). The total cumulative exposure to NRTIs was not associated with an increased risk of lactic acidosis, nor was the cumulative exposure to any of the 4 NRTIs studied. According to these results, monitoring of creatinine clearance, especially in patients with a low nadir CD4+ T lymphocyte count, could lead to modifications in antiretroviral therapy in order to diminish the risk of occurrence of lactic acidosis.

We performed a retrospective study to evaluate, under routine circumstances, the tolerance and immunovirological changes associated with antiretroviral regimens that contain nevirapine in 137 patients (88% were antiretroviral experienced). During a mean follow-up of 11 months, 33% of patients reported side effects attributed to nevirapine, and 21% discontinued treatment because of poor tolerance. Administration of antihistamines or corticosteroids at the initiation of treatment was not protective against adverse events (relative risk, 0.82; 95% confidence interval, 0.49-1.38). The proportion of patients with hepatitis C virus (HCV) and/or hepatitis B virus (HBV) coinfection who had alanine aminotransferase levels of >100 IU/L increased from 19.4% at baseline to 42.9% at month 12 of follow-up (P=.02). We noticed a significant increase of the proportion of patients with total cholesterol levels of >5.5 mM (P=.02). We have shown that there is a high level of discontinuation of nevirapine therapy in clinical practice and that side effects were not prevented by administration of antihistamines or corticosteroids. Coinfection with HCV or HBV increased the risk of hepatotoxicity, which lead to the cautious use of nevirapine for such patients.

Purpose. – The management of amoebic liver abscess includes antiamoebic drugs combined or not with percutaneous puncture or surgical drainage. This study was to suggest a decision tree for the therapeutic approach of such feature. Methods. – We report a retrospective analysis of 20 imported cases with amoebic liver abscesses admitted at the Department of Tropical Diseases during 1995–1999 at the Bordeaux University Hospital Centre, France, and a review of the literature. Results. – The twenty patients were 14 males and 6 females, mainly 20 to 40 years old. The clinical presentation was mainly accounting a painful liver enlargement with hyperthermia. The echographic picture was mostly represented by a unique liver element located at the liver right lobe. They were numerous in an HIV infected patient. Thirteen patients have been treated using a medical therapeutic approach. A percutaneous puncture has been necessary for 4 cases. A percutaneous drainage has been realised for two patients as regard to the persistence of the hepatalgia occurrence. A surgical drainage has been experienced by two patients after a lack of efficacyof a percutaneous drainage, after rupture of an abscess treated medically, respectively. A review of the literature and the analysis of the 20 cases history have been used to determine a therapeutic algorithm. Conclusion. – The occurrence of immediate complications at onset must indicate a first line surgical drainage procedure. Beside this situation, risk factors for rupture must be assessed (high size abscess, pejorative localization), as well as poor prognosis feature (liver failure, bacteraemia). If no pejorative condition occurs, a first-line exclusive medical approach can be undertaken with a clinical efficacy evaluation at H72. Otherwise, the indication of the percutaneous drainage must be discussed.

Abstract Purpose: The objectives of the study were to assess the effects of pravastatin on plasma HIV RNA, lipid parameters, and protease inhibitor (PI) concentrations in patients treated with PI-containing regimens and with total cholesterol (TC) ⩾5.5 mmol/L.Method: A clinical trial including patients randomized to receive pravastatin or matching placebo for 12 weeks was implemented. Results: Twelve patients were included in the pravastatin group and 9 in the placebo group. At week 12 (W12), no patient had experienced virological failure. Between week 0 (W0) and W12, the median differences for TC were –1.4 mmol/L in the pravastatin group and +0.2 mmol/L in the placebo group (p = .005); for LDL, they were –1.0 mmol/L and +0.3 (p = .007), respectively. A significant decrease of the PI concentration (12 hours after administration) ratio W12 – W0/W0 was noticed in the pravastatin group (–0.2 [interquartile range, –0.3 to –0.1] as compared with the placebo group (0.1 [IQR, 0.0 to 0.3]) (p = .03). When the study was restricted to patients treated with lopinavir/ritonavir, a decrease from 3.8 μg/mL at baseline to 2.9 μg/mL at W12 was noticed in the pravastatin arm (p = .04) but not in the control arm (p = 1.00). No clinical adverse event reached a severity of grade 3. Conclusion: We observed in this study that the use of pravastatin in PI–treated patients was not associated with major change in the plasma HIV RNA on 12 weeks of follow-up. However, we found a trend of decrease of the trough PI concentration at W12, suggesting a possible drug–drug interaction of pravastatin on PI metabolism.

CASE REPORT: Sarcoidosis-Associated Hepatitis C Virus Infection

: Although several reports of sarcoidosis have been reported in hepatitis C virus (HCV)-infected patients treated with interferon-alpha, this association has never been described in nontreated HCV patients. We report two cases of sarcoidosis associated with chronic hepatitis C infection. The patients developed multivisceral sarcoidosis (cutaneous, lungs, nodes) at two and at least six years after the presumed date of infection. One patient obtained remission of sarcoidosis with corticosteroid treatment but the other remained corticodependent. The levels of hepatic enzymes were not significantly modified throughout the course of corticosteroid therapy. In conclusion, these case reports suggest that HCV itself could induce a granulomatous reaction in chronic HCV-infected patients through the stimulation of the cellular immune system. It could be of interest to test for HCV infection all patients diagnosed with sarcoidosis and to watch over every treated or nontreated hepatitis C infected patient for the development of granulomatous lesions.

Portal vein thrombosis (PVT) seems rare among HIV infected patients. Even though, the report of such cases is of great interest because it may help to determine the factors of occurrence. We describe cases of PVT in 4 HIV-infected men, aged 32 – 64. Two of them were co-infected with hepatitis C virus (HCV). The four patients had a history of disseminated mycobacterial infection (1 case of tuberculosis, 3 cases of mycobacterium avium complex infection) with abdominal lymphadenitis. Despite HAART, their immunodeficiency was profound (CD4: 65 to 216/mm3). At the time of diagnosis, two patients were treated with protease-inhibitor containing regimen: indinavir (1case), ritonavir-saquinavir (1case). PVT was revealed by haematemesis (1 case), abdominal pain (1 case), anasarca (2 cases). In three patients, the diagnosis of PVT was confirmed by imagery (echo-doppler or angio- RMI), and for the last patient, PVT was found during the transjugular intrahepatic porto-systemic shunt-set up. A low level of C protein was diagnosed in 1case. Cirrhosis was not found in HIV-HCV co-infected patients. Two patients died early after diagnosis, one patient died 3 years after the one-set of symptoms. Various factors may cause the development of a PVT in HIV infected patient. Serious immunodeficiency, opportunistic infections such as tuberculosis and mycobacterium avium complex related infection with abdominal lymphadenitis can further the development of PVT. Protease-inhibitor might have facilitated the process. Due to the severe prognosis of advanced cases, early evocation of diagnosis is needed.

Objective: To describe the response to combinations of two nucleoside reverse transcriptase inhibitors (NRTIs) initiated early in the course of HIV infection under routine circumstances and to research prognostic factors indicating good virologic response. Setting: Patients of the Aquitaine Cohort, a hospital‐based open cohort that had been recruiting since 1987 in five public hospitals of the Aquitaine region in southwestern France. Methods: Prospective cohort study of antiretroviral‐naive patients with CD4+ cell counts >0.350 × 109/L who started dual NRTI therapy between January 1996 and June 1997. Intent‐to‐treat analysis and multivariate logistic regression were used with data collected up to March 31, 1998. Results: In this study, 130 patients were enrolled with a median follow‐up of 14 months. At the time of first prescription, 79% were in U. S. Centers for Disease Control and Prevention (CDC) group A, 16% in group B, and 5% in group C; median CD4+ cell count was 0.466 × 109/L and median HIV RNA level was 4.52 log10 copies/ml. The two main combinations used were zidovudine (AZT) plus zalcitabine (ddC; 38%) and AZT plus didanosine (ddI; 37%). At week 52, median CD4+ and HIV RNA responses were, respectively, +80 cells and ‐1.6 log; the proportions of patients with HIV RNA level <5000 and <500 copies/ml were 70% and 45%, respectively, and 96% of the patients had a CD4+ cell count >0.350 × 109/L at that time. At their last follow‐up, 3 patients had reached been diagnosed with full‐blown AIDS and the AIDS‐free survival probability at 1 year was 98.2% (95% confidence interval [CI], 93.1‐99.6); 1 death had occurred. The only significant variable associated with an undetectable HIV RNA level at 1 year was a lower HIV RNA level at the first prescription of dual therapy. Conclusion: Our data indicate that dual nucleoside combinations could be a therapeutic option for patients diagnosed and observed during follow‐up in the early course of HIV infection.
