Clinically latent myeloproliferative disorders (MPDs) are important causes of what would otherwise be considered idiopathic hepatic (HVT) or portal vein thrombosis (PVT). They may be difficult to diagnose initially because the peripheral blood count may be normal at the time of thrombosis. A strong association between an activating mutation of the gene encoding one of the Janus kinase family of tyrosine kinases (JAK2(V617F)) and the Philadelphia chromosome-negative MPDs has been identified. We have studied 19 patients with unexplained HVT or PVT and tested for JAK2(V617F). Fourteen (74%) of the 19 patients were heterozygous for JAK2(V617F) but did not meet diagnostic criteria for a MPD at the time of presentation with thrombosis. Prolonged follow-up established the presence of an overt MPD in 13 of the 14 patients after a median duration of 38 months. We recommend testing for JAK2(V617F) in all patients with unexplained HVT or PVT, to identify latent MPDs and prevent potential complications.
Setting Drug resistance threatens tuberculosis (TB) control, particularly among HIV-infected persons. Objective We surveyed antiretroviral therapy (ART) programs from lower-income countries on prevention and management of drug-resistant TB. Design We used online questionnaires to collect program-level data in 47 ART programs in Southern Africa (14), East Africa (8), West Africa (7), Central Africa (5), Latin America (7) and Asia-Pacific (6 programs) in 2012. Patient-level data were collected on 1,002 adult TB patients seen at 40 of the participating ART programs. Results Phenotypic drug susceptibility testing was available at 36 (77%) ART programs, but only used for 22% of all TB patients. Molecular drug resistance testing was available at 33 (70%) programs and used for 23% of all TB patients. Twenty ART programs (43%) provided directly observed therapy (DOT) during the whole treatment, 16 (34%) during intensive phase only and 11 (23%) did not follow DOT. Fourteen (30%) ART programs reported no access to second-line TB regimens; 18 (38%) reported TB drug shortages. Conclusions Capacity to diagnose and treat drug-resistant TB was limited across ART programs in lower income countries. DOT was not always implemented and drug supply was regularly interrupted, which may contribute to the global emergence of drug resistance.
We conduct a longitudinal descriptive study in the department of infectious diseases to CHU of Point G during 18 months. It concerned adult patients referred from another care center. All the patients underwent systematic clinical examination and complementary exploration. Our sample was 352 HIV+ patients, with a mean age of 37.8 ± 9.8 years and a sex ratio (M/F)=0.94 shared among patients receiving ARV treatment (ART-s) and not (n-ART). Delay of reference was 5 ± 4.4 days. All patients benefited from clinical and paraclinical examinations. In both groups patients were mostly from level II. On admission, 132 cases were ART-s (38%). The main reasons for consultation were mainly fever [87.9%, p <0.05] and vomiting [17.4%, p =0.005] in the ART-s. Cough (p=0.9), and diarrhoea (p=0.5] were most noted in the n-TARV no statistically significant (no SS). Other reference reasons were similar in the 2 groups: headache (p=0.4), dyspnea (p=0.1). Selected diagnoses were dominated by tuberculosis (p=0.6) for n-ART no SS. Nontuberculosis infectious pneumonia (p=0.8) and cerebral toxoplasmosis (p=0.8) were comparable in the two groups. Severe systemic bacterial infections occurred more noted in the n-TARV (p=0.7). Malaria has been the main non-AIDS defining disease in the n-ART [-p=0.07] no SS. Patients were seen to late stage a corollary of a more collapsed of immunity in n-ART group [93.3%, p <0.05]. The fatality rate was similar in both groups (43.2%). Pathological factors were mainly tuberculosis (p=0.3) no SS. The factors involved significantly in TARV-s were non-tuberculosis bacterial pneumonia (p=0.001). The hospital mortality of HIV and AIDS is still important. Despite free ARVs and the large number of support center, the delay in diagnosis is a key as well as the lack of monitoring of patients factor.
The authors report a case of systemic lupus associated with a composite heterozygosis SC with thalassemic component in a 19-year-old patient hospitalized for anemia and polyarthralgia who has a staturoponderal delay, macular erythematous lesions in butterfly wings on the face and ears, photosensitivity, puffy face, alopecia, pubic and axillary hair loss, scalp dermatophytosis, painful swelling of the interphalangeal joints, wrists and knees. The hemoglobin electrophoresis showed a compound heterozygote SC associated with β thalassemia. Antinuclear antibodies were positive with an anti-Sm positive antibody. Conclusion: The diagnosis of both diseases can be difficult when symptoms are concomitant and look alike.
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. This disease is the second leading cause of infectious mortality in the world after infection with the human immunodeficiency virus. We report a case of multifocal tuberculosis with neuromuscular and ocular localization in an HIV-1 immunosuppressed patient in clinical and virological failure following therapeutic discontinuation due to non-compliance. This is a 43-year-old immunocompromised HIV1 patient with a history of cerebral toxoplasmosis in 2016 who consulted for right hemiplegia. These symptoms would go back to about 3 days marked by a deficit of progressive installation of the right hemicorps preceded by diffuse headaches, of moderate intensity without triggering factor radiating to the eyes associated with an intermittent fever with periods of spontaneous remissions, night sweats and chills, non-selective anorexia, non-increasing physical asthenia and unquantified weight loss. Management was 8-month antituberculous treatment, combining the first two months isoniazid (INH), rifampicin (RMP), pyrazinamide (PZN) and ethambutol (EMB), then the next 6 months (INH) and rifampicin (RMP). The reintroduction of the same antiretroviral protocol and a reinforcement of the therapeutic education made it possible to observe a decrease of the viral load. Treatment of ocular involvement was instituted with Timosol 1 drop in the eyes morning and evening and Diclocid 1 mg/ml: 1 drop in the eyes in the morning.
