Occlusion intestinale en zone d’endémie : penser aussi à la tuberculose

In Sub-Saharan Africa, unusual aspects of tuberculosis always lead to cases of death because of wandering diagnosis, despite real possibilities of cure.     

Optimizing the control group for evaluating ART outcomes: can outpatient claims data yield a better control group?

PurposeWe previously developed a subfertile comparison group with which to compare outcomes of assisted reproductive technology (ART) treatment. In this study, we evaluated whether insurance claims data in the Massachusetts All Payers Claims Database (APCD) defined a more appropriate comparison group.MethodsWe used Massachusetts vital records of women who delivered between 2013 and 2017 on whom APCD data were available. ART deliveries were those linked to a national ART database. Deliveries were subfertile if fertility treatment was marked on the birth certificate, had prior hospitalization with ICD code for infertility, or prior fertility treatment. An infertile group included women with an APCD outpatient or inpatient ICD 9/10 infertility code prior to delivery. Fertile deliveries were none of the above. Demographics, health risks, and obstetric outcomes were compared among groups. Multivariable generalized estimating equations were used to calculate adjusted relative risk (aRR) and 95% confidence intervals (CI).ResultsThere were 70,726 fertile, 4,763 subfertile, 11,970 infertile, and 7,689 ART-treated deliveries. Only 3,297 deliveries were identified as both subfertile and infertile. Both subfertile and infertile were older, and had more education, chronic hypertension, and diabetes than the fertile group and less than the ART-treated group. Prematurity (aRR = 1.15–1.17) and birthweight (aRR = 1.10–1.21) were increased in all groups compared with the fertile group.ConclusionAlthough the APCD allowed identification of more women than the previously defined subfertile categorization and allowed us to remove previously unidentified infertile women from the fertile group, it is not clear that it offered a clinically significantly improved comparison group.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10815-021-02111-6.     

Rosai Dorfman disease diagnosed by fine‐needle aspiration cytology in a young man with HIV infection

RDD (Rosai Dorfman disease) is a rare and benign histiocytic proliferative disorder of unknown etiology. FNAC (Fine‐needle aspiration cytology) is a useful and reliable tool for the diagnosis of RDD, and as such, biopsy is avoidable.     

Antibodies to hepatitis C virus in patients with hepatocellular carcinoma.

To study the potential relationship between the hepatitis C virus (HCV), the major etiologic agent of parenterally transmitted non-A, non-B hepatitis, and the development of hepatocellular carcinoma (HCC), we tested the presence of anti-HCV antibodies in sera from a large panel of HCC patients of different racial and geographical origins. Anti-HCV antibodies were detected in 82 out of 114 (71.9%) HBsAg-negative HCC patients and in 15 out of 53 (28.3%) HBsAg-positive patients. No significant difference in the prevalence of anti-HCV antibodies was found in the HBsAg-negative HCC patients when they were divided according to presence of anti-HBs and/or anti-HBc antibodies, or absence of all hepatitis B virus (HBV) serological markers. The prevalence of anti-HCV antibodies was similar in HCC patients of Caucasian and African origin. No differences were noted when the patients were grouped according to sex. The mechanisms by which HCV might contribute to the development of HCC need to be further investigated. As for HBV infection, the necro-inflammation associated with HCV infection may induce cirrhosis, regeneration and eventually malignant transformation. The finding that few anti-HCV patients had HCC which is not superimposed on cirrhosis suggests that HCV could, however, exert some direct effect on the development of HCC.     

Peripartum idiopathic myocardiopathy: prospective echocardiographic study

Still frequent in Africa, the idiopathic peripartum cardiomyopathy (PPC) is the subject of only few prospective studies. The aim of this prospective work was to assess the echocardiographic abnormalities of the PPC and to determine on 26 patients the evolution and the prognostic factors of this disease. Six women had mild to moderate pericardial effusion. The abnormalities of the wall motion, constantly found, were diffuse in 20 cases (77.1%) and localized or prevalent on the interventricular septum or the left ventricular posterior wall in the other cases. The cardiac chambers were dilated in 24 cases (92.3%). Left ventricular hypertrophy was noted among 16 patients (61.5%); it was eccentric in 15 cases. The left ventricular systolic dysfunction was constant. The other abnormalities were: the abnormal left ventricular relaxation (one case), low mitral and aortic flow (12 cases), the mitral (21 cases) and tricuspid regurgitation (five cases). One noted a septal hypertrophy and an isolated dilatation of the right ventricle. The mean follow-up was 7.3 +/- 1 month (1-18 months). Two patients died at the 4th and 8th month. Among the 24 survivors, 11 had normalized were: the gestity (p = 0.01), the parity (p = 0.01), the cardiothoracic ratio (p = 0.04), the left ventricular volumes (p = 0.02), and the parameters of left ventricular function. The echocardiography of patients with PPC usually shows a pattern of dilated and hypokinetic cardiomyopathy, but many variations are possible. Most of the patients keep echocardiographic abnormalities after mean term follow-up.     

Antiretroviral treatment outcome in HIV-1-infected patients routinely followed up in capital cities and remote areas of Senegal,Mali and Guinea-Conakry

Introduction

Access to antiretroviral treatment (ART) becomes more and more effective in resource-limited settings (RLS). However, this global effort would be even more profitable if the access to laboratory services especially in decentralized settings was strengthened. We report the virological outcome and HIV-1 drug resistance in three West African countries using dried blood spots (DBS) samples.

Methods

We included HIV-1-infected adults on ART ≥6 months and followed up in capital cities and decentralized sites in Senegal, Mali and Guinea-Conakry. Patients were consecutively enrolled and DBS were collected in field conditions and kept at ambient temperature before transfer to the reference laboratory. Viral load (VL) was quantified using the NucliSENS EasyQ HIV-1 v1.2. Genotyping of HIV-1 pol gene was performed using in-house protocol.

Results

Of the 407 participants, 119, 152 and 136 were from Senegal, Mali and Guinea-Conakry, respectively. The median treatment duration was 36 months [IQR: 6–136]. Virological failure (VF) (VL≥3log₁₀ copies/mL) was observed in 26% (95% confidence interval (CI), 18–35; n=31), 11% (95% CI, 6–17; n=16) and 24% (95% CI, 17–32; n=33) of patients in Senegal, Mali and Guinea-Conakry, respectively (p=0.001). Of samples presenting VL≥3log₁₀ copies/mL (n=80), 70 were successfully genotyped. At least one drug resistance mutation (DRM) was detected in the following proportions: 70% (95% CI, 50–86; n=19), 93% (95% CI, 68–100; n=14) and 68% (95% CI, 48–84; n=19) in Senegal, Mali and Guinea-Conakry, respectively (p=0.22). Twenty-six per cent (26%; 95% CI, 16–38; n=18) of patients in VF harboured wild-type viruses, which is likely indicative of weak adherence. Phylogenetic analysis showed the predominance of CRF02_AG subtype (73%; 95% CI, 61–83; n=51).

Conclusions

We describe the ART outcome in capital and rural settings of Senegal, Mali and Guinea-Conakry. Our results in all of the three countries highlight the need to reinforce the ART adherence in order to minimize the occurrence of drug resistance. In addition, these findings provide additional evidence that the use of DBS as a sampling support could assist virological monitoring of patients on ART in remote areas.     

Volvulus gastrique récurrent révélant un hémangio-endothéliome malin de l’antre. A propos d’une observation

Gastric volvulus is an abnormal rotation of the stomach on its axis which acute form requires emergent care. Nevertheless, unusual symptoms of this disease at presentation, often lead to delay diagnosis. We report a case of acute gastric volvulus revealing a malignant hemangio endothelioma of the antrum in a 62 years old man. He presented recurrent signs of gastric outlet obstruction mimicking Borchardt’s syndrome because endoscopy of the upper digestive tract or nasogastric probe were not possible to carry out. Use of CT scan was also helpful to set up diagnosis of volvulus leading to laparotomy which highlighted the antral tumour. So, partial gastrectomy was performed and postoperative course was uneventful. After four months, the clinical course was good and a gain of 3 kg of weight was noted.
