[Primary isoniazid preventive therapy : A strategy still relevant in the era of test and treat ; literature review]. / Chimioprophylaxie antituberculeuse primaire à l'isoniazide : une stratégie d'actualité à l'ère du tester et traiter ; revue de la littérature.

BACKGROUND: Tuberculosis remains a public health threat responsible as recently as 2018 for more than one million deaths. Chemoprophylaxis with isoniazid is one of the strategies implemented to control the disease. Although it is not yet widely prescribed, its utilization raises additional questions in the "test and treat" era of for anti-retroviral therapy. The objective of this study is to review the different randomized controlled trials of antitubercular Isoniazid Preventive Therapy (IPT). We have distinguished (a) "efficacy trials" (ET) comparing IPT to a placebo or the absence of chemoprophylaxis and (b) "IPT regimen trials" (RT) comparing IPT to one or several other regimens. METHODS: Literature search (keywords from published articles found in the Medline and Scopus data bases: "tuberculosis", "prophylaxis", "HIV", "randomized controlled trial") and standardized reading of selected articles reporting results from randomized trials of IPT in HIV-infected people. RESULTS: Eighteen selected trials (11 ET and 7 RT), including 19,725 participants. The regimens studied were 3H, 6H, 9H, 12H, 12H, 36H/2RZ, 3RH, 3RZ, 3RHZ, and 3HP [H: Isoniazid, R: Rifampicin, Z: Pyrazinamide, P: Rifapentine]. LOCATIONS: Ten in Africa, three in Haiti, one in India, one in the USA, one in the Americas and two multi-continental trials. In ET with or without antiretrovirals (ART), IPT significantly reduces the risk of tuberculosis, by 32 to 71%. In ET prior to ART, IPT does not appear to reduce mortality. In ET in patients receiving ART, on the other hand, IPT reduces mortality. As regards RT, there seems to be no reason to prefer other regimens to IPT. Tolerance is good. Importantly, IPT may reduce (rather than worsen) the risk of multidrug-resistant bacilli selection by decreasing the number of TB episodes and, consequently, the number of curative tuberculosis treatments. CONCLUSION: Far from becoming obsolete due to ARV treatment, IPT has remained a timely and relevant intervention.

Precore G1896A mutation is associated with reduced rates of HBsAg seroclearance in treated HIV hepatitis B virus co-infected patients from Western Africa.

The nucleotide substitution G1896A on the precore (pc) region has been implicated in virological and serological responses during treatment in hepatitis B virus (HBV)-infected patients. Whether this mutation affects the therapeutic course of HIV-HBV co-infected patients, especially from Western Africa, is unknown. In this prospective cohort study, 86 antiretroviral (ARV)-naïve HIV-HBV co-infected patients from Côte d'Ivoire, initiating ARV-treatment containing lamivudine (n = 53) or tenofovir (n = 33), had available baseline pc sequences. Association of the pcG1896A mutation with time to undetectable HBV-DNA, hepatitis B "e" antigen (HBeAg) seroclearance (in HBeAg-positive patients), and hepatitis B surface antigen (HBsAg) seroclearance was evaluated using Cox proportional hazards regression. At ARV-initiation, median HBV-DNA was 6.04 log10 copies/mL (IQR = 3.70-7.93) with 97.7% harbouring HBV genotype E. Baseline pcG1896A mutation was identified in 51 (59.3%) patients, who were more commonly HBeAg-negative (P < .001) and had basal core promotor A1762T/G1764A mutations (P < .001). Patients were followed for a median 36 months (IQR = 24-36). Cumulative proportion of undetectable HBV-DNA was significantly higher in patients with baseline mutation (pcG1896A = 86.6% vs no pcG1896A = 66.9%, P = .04), but not after adjusting for baseline HBV-DNA levels and anti-HBV agent (P = .2). No difference in cumulative proportion of HBeAg seroclearance was observed between mutation groups (pcG1896A = 57.1% vs no pcG1896A = 54.3%, P = .7). Significantly higher cumulative proportion of HBsAg seroclearance was observed in patients without this mutation (pcG1896A = 0% vs no pcG1896A = 36.9%, P < .001), even after adjusting for baseline HBsAg quantification and anti-HBV agent (P < .001). In conclusion, lacking the pcG1896A mutation before ARV initiation appeared to increase HBsAg seroclearance rates during treatment. The therapeutic implications of this mutation need further exploration in this setting.

[Impact of access to antiretroviral therapy in Côte d'Ivoire]. / Bilan de l'accès aux antirétroviraux en Côte d'Ivoire.

In 1998 UNAIDS implemented the national drug access initiative (DAI) in Côte d'Ivoire. The Ivorian government took the DAI over in 2000 with the support of the Global Fund and Presidential Emergency Program For AIDS Relief (PEPFAR). The ensuing affordability of antiretroviral therapy (ART), medical staff training, and healthcare equipment allowed Ministry of Health to improve HIV care throughout the country. Since 2008 ART and follow-up monitoring have been free of charge for people living with HIV/AIDS (PLWHA). In January 2009 a total of 57,833 PLWHA received ART and follow-up at 274 HIV care centers. Use of ART has improved the life expectancy of PLWHA. However morbidity and mortality remained high during the first year of ART implementation with respective frequencies of 5-10% person-year (PY) and 2-3% PY. Morbidity was mainly related to infectious disease (tuberculosis and bacteriaemia) and earlier onset of adverse events (AE). In most cases ART has been well tolerated. The main adverse effects have been anemia, neuropathy, skin toxicity and liver enzyme elevation. The incidence of stage 3/4 AE has been low (< 2 %PY). Although overall compliance has been good (<80%), data among children and adults suggest the need for further work to reinforce support mechanisms. Convincing results have been obtained in the management of PLWHA. Nevertheless greater funding and commitment must be given to management of opportunistic infections and side effects and to development of nutrition support services.

[Hyperactive malarious splenomegaly: diagnosis and therapeutic problems in adults]. / Splénomégalie palustre hyperactive: problèmes diagnostiques et thérapeutiques chez l'adulte.

The chronic forms of malaria are scarce. We report a case of an hyperactive malarious splenomegaly. This case concerns a 69 year-old man residing in a village of Côte d'Ivoire. He had massive splenomegaly type IV. He was admitted in hospital for progressive loss of weight and moderate fever He presented also asthenia, anaemia and regular hepatomegaly. The haematological, biochemical, immunological and radiological exams ruled out trypanosomiasis, visceral leishmaniasis, tuberculosis, bilharziasis diseases and neoplasia process. His age, the massive splenomegaly, the anaemia, the high antimalarial IgM antibodies in immunofluorescence and the favourable response to the prolonged administration of antimalarial treatment led to the diagnosis of hyperactive malarious splenomegaly despite the detection of Plasmodium falciparum in blood. This observation allows to underline the frequency of this possible underestimated chronic form of malaria in Africa and shows the necessity to consider it seriously when facing massive splenomegaly.

[Three new cases of visceral leishmaniasis in Côte d'Ivoire]. / Trois nouveaux cas de leishmaniose viscérale autochtone en Côte d'Ivoire.

The objective of this work is to report three cases of visceral leishmaniasis in non-HIV infected native patients in Côte d'Ivoire. The three observations concerned adults aged of 31 and 65 and a five years old child without particular medical or surgery histories. Factors associated with visceral leishmaniasis regarding the younger and the older adults were respectively young age, chronic lymphoid leukaemia and Burkitt lymphoma. Clinical features in the three cases were chronic fever a myeloproliferative syndrome with wasting syndrome and pancytopenia. The diagnosis was confirmed by the existence of Leishmania in bone marrow, ganglionic juice and splenic samples. The species of Leishmania was not identified. Specific treatment was based on intravenous amphotericin B (Fungizone) relayed by Glucantim in one case because of side effects; however the treatment has been unsuccessful. These three new cases show that visceral leishmaniasis is a reality in Côte d'Ivoire therefore an epidemiological survey is requested in order to identify Leishmania species, reservoirs and vectors.

[Efavirenz versus indinavir among HIV-1 naive patients in Abidjan (Ivory Coast)]. / Efavirenz versus indinavir chez les patients naïfs infectés par le VIH-1 à Abidjan (Côte d'Ivoire).

OBJECTIVE: The authors had for aim to compare the therapeutic efficiency and tolerance of 2 NRTI+efavirenz (EFV) versus 2 NRTI+indinavir (IDV) in HIV infected adults in Abidjan. METHODS: A retrospective and multicentric study was made on 327 HIV-1 naive patients, 142 in the EFV group and 185 in the IDV group followed in Abidjan from November 1998 to December 2003. The analysis concerned clinical advents (opportunistic infections) and immunovirological parameters (CD4, viral load). Patients received 2 NRTI such as AZT+3TC or D4T+3TC combined either with EFV or IDV. The principal judgement criterion was therapeutic failure. We assessed the percentage of patients with undetectable viral load and the frequency of grade 3-4 adverse effects after 24 months of follow-up. RESULTS: Clinical improvement of patients' state and regression of opportunistic infections were identical in the two groups. The average gain of CD4 was superior to 177 in EFV versus +219 in IDV (p=0.004). The percentage of patients with undetectable viral load was 66% for EFV versus 59% for IDV (p=0.04). The frequency of adverse effects was more elevated with EFV than IDV, 39% versus 23% (p=0.002) initially, but seemed to decrease later. CONCLUSION: HAART with EFV is at least as efficient as with IDV in terms of reduction of viral load and increased CD4 count and is an excellent low-cost first line treatment.

[Fluconazole 1200mg or 800mg for cryptococcal meningitis treatment in Ivory Coast]. / Fluconazole 1200mg ou 800mg dans le traitement de la cryptococcose neuroméningée en Côte d'Ivoire.

OBJECTIVE: Assessing the use of high-dose fluconazol monotherapy (1200mg or 800mg) in the treatment and prognosis of HIV-associated cryptococcal meningitis in Ivory Coast. PATIENTS AND METHODS: A retrospective study carried out from August 2008 to August 2011 based on patients charts suffering from CM in the Abidjan Tropicals and Infectious Disease Unit. Mortality rate and associated factors were analyzed. RESULTS: Forty-six cases of cryptococcal meningitis (2.5% of hospitalizations) were included. The sex-ratio was of 1.2. The median age was 40.5 [35-47] years. The symptomatology was subacute (93.5%). The main clinical symptoms were syndrome of pure meningeal irritation (65%), fever (100%); 35% of patients had encephalomeningits. Twenty-one (45.7%) was ART-naïve patients. Fluconazole 1200mg was prescribed to 29 (63%) patients. Therapeutic lumbar punctures were performed in 42 (91.3) patients. The mortality rate was 50%. Significant predictors of mortality were encephalomeningitis and therapeutic lumbar puncture. CONCLUSION: Cryptococcal meningitis associated mortality remains high despite the use of high-dose fluconazole monotherapy. Therapeutic lumbar punctures help to improving the prognosis.

[Observance of antiretroviral treatments: African specificities]. / L'observance aux traitements antirétroviraux: particularités Africaines.

Since the Durban conference in 2000, the initiatives of access to antiretroviral therapy (ART) have expanded in sub-Saharan Africa. It is of high interest to monitor observance to HAART, in a context of increasing ART use, a rapid increase of patients under HAART, and the sociocultural specificities in Africa. In sub-Saharan Africa the concept of disease without cure does not exist and a disease always has or is attributed an external cause. Optimizing observance is a key element for the success of implementation programs for which we recommend a light monitoring to follow-up patients and the use of first line and effective antiretroviral drugs, with a low genetic barrier (efavirenz, nevirapine). The consequences of non-adherence are extremely negative for a patient in Africa, for whom we have few assessment tools and a limited number of ART. Improvement of adherence requires the involvement of all health care actors including traditional healers.

[Profound mycoses in AIDS in Abidjan (Côte d'Ivoire)]. / Mycoses profondes au cours du SIDA à Abidjan (Côte d'Ivoire).

During 1995, among 1105 HIV patients explored in our department, 64 presented a deep fungic infection (5.8%). The yeast was searched for in cerebrospinal fluid, blood, urine, and bronchoalveolar aspiration. Isolated germs were Cryptococcus neoformans (95%), Candida tropicalis (1 case), Saccharomyces cerevisiae (1 case) et Aspergillus fumigatus (1 case). Results of treatment with amphotericin B were: recovery (9%), clinical success (11%), out of sight (14%), letality (66%), relapse (23%) and side effects (19%). We emphasized diagnostical and therapeutical difficulties, and bad prognostic of mycoses in patients with AIDS.

[Morbidity and mortality of tetanus in the infectious and tropical diseases department in Abidjan 1985 - 1998]. / Morbidité et mortalité du tétanos dans le service des maladies infectieuses et tropicales d'Abidjan (1985-1998).

UNLABELLED: In spite of the increase of the antitetanus immunization coverage, tetanus is still one of the main causes of morbidity and mortality in Côte d'Ivoire hospitals. OBJECTIVE: The purpose of this study was to analyse the epidemiological, clinical and prognosis aspects of tetanus in the department of infectious diseases in Abidjan. METHODS: A retrospective analysis was carried out from patients files admitted for tetanus in this department from 1985 to 1998. Tetanus diagnosis was based on clinical arguments. RESULTS: Within a period of fourteen years, 1870 cases of tetanus representing 3% of hospitalised cases were admitted in the infectious diseases department. For 1387 patients answering to the inclusion criteria of the study the ratio MIF was 2.5. The median age was 28 years old (1-85 years). The entrance doors were dominated by cuts (49.3%) and intramuscular injections of drugs (18.7%). Despite the complete vaccination, 7 patients have presented tetanus (0.5%). About 17% have presented progressive complications especially cardio-respiratory complications (41.5%). The total lethality was 31.9% and the after- effects rate 2.3%. The factors of poor prognosis were the age > 60 years old, IM injections, generalised aspect, group III of severity and presence of complications. CONCLUSION: Tetanus frequency certainly drops in infectious and tropical diseases department, but the lethality remains high therefore a reinforcement of the vaccination efforts and a management of patients are recommended.

[Severe malaria in native adults in Abidjan (Côte d'Ivoire)]. / Paludisme grave de l'adulte autochtone à Abidjan (Côte d'Ivoire).

Our retrospective study carried out from 1985 to 1998 in the Unit of Infectious Diseases in Abidjan aimed at describing the epidemiological, clinical and prognosis features of severe malaria among native adults. Within 14 years, we have listed 274 cases of severe malaria for 54 098 hospitalizations (0.5%). 164 men and 110 women were recorded (sex-ratio = 1.5), aged of 33 years (16-86), among them 48% were HIV positive. 23% of the patients had already received an antimalarial treatment. The main clinical presentation was cerebral malaria (78%). The other manifestations were respiratory symptoms (13%), kidney failure (11%), anaemia (11%), macroscopic haemoglobinuria (6%), hypoglycaemia (9%), cardiovascular shock (4%). The average parasite load in blood was 27 222 plasmodium/microl (25 000 - 180200). The treatment used was quinine IV (172 patients), and arthemeter (102 patients). The outcome was favourable in 232 cases (84%) and 42 patients died. Prognosis factors identified were age > 65 years, Glasgow coma score < 7, convulsions, cardio-vascular shock, macroscopic haemoglobinuria. HIV infection has not been identified as a pejorative factor Our results confirm that severe malaria in native adult is a reality in tropical area. This study shows how difficult it is to have an adequate care management regarding this pathology in our context.

[Adult non-viral lymphocytic meningitis in Abidjan (Côte d'Ivoire)]. / Méningites lymphocytaires non virales de l'adulte à Abidjan (Côte d'Ivoire).

Our prospective and longitudinal study aimed to analyse the aetiologies, clinical features and prognostic of non viral lymphocytes meningitis (NVLM). We recruited 131 patients, 77 males (59%) and 54 females (41%) sex-ratio 1.4. The mean age was 35 years [15-67]. 117 patients were HIV positive (89%) and 14 (11%) were HIV negative. Feverish meningoencephalitis was present in 85% of cases, with 7 days for mean delay of admission into hospital. 80 germs were found in the C.S.F. 70 Cryptococcus neoformans, 4 Mycobacterium tuberculosis, 3 Streptococcus pneumoniae, 1 Candida albicans, 1 Neisseria meningitis and 1 Trypanosoma gambiense. 63 aetiologies were linked to lymphocytes meningitis by indirect deduction: 41 cases of tuberculous meningitis with lung X-ray anomalies and M. tuberculosis in sputum (11 times), 11 cases of cerebral malaria with Plasmodium falciparum in blood, 11 cases of cerebral toxoplasmosis by significant features with cerebral tomodensitometry. Letality was 53%, 35% of patients improved and 12% were lost to follow-up. Our study shows the difficulties in the management of the NVLM, due to the delay of diagnosis, particularly for tuberculous meningitis.

[Neurosurgical complications of purulent meningitis in the tropical zone]. / Complications neurochirurgicales des méningites purulentes en zone tropicale.

Our retrospective study concerned 35 cases of surgical complications related to bacterial meningitis in 16 adults and 19 children. The mean age was 28 years for adults (15-56 years), and 6 months for children (1-12 months). Portal of entry for meningitis was found in 12 cases (35%): 8 sinusitis and 4 otitis. Delay to appearance of complications was 4.5 days, and to diagnosis confirmation 9 days with CT scan (17 cases), and transfontanellar ultrasonography (19 cases). The complications were: hydrocephalus, 19 cases (54%), brain empyemas, 7 cases (20%), abscesses, 10 cases (28.5%), ventriculitis, 2 cases (6%). Twenty-two bacteria were isolated from the CSF: Streptococcus pneumoniae (15 cases), Haemophilus influenzae (5 cases), Neisseria meningitidis (1 case), and Escherichia coli (1 case). Fourteen patients underwent neurosurgical treatment based on aspiration in case of suppuration and external drainage in case of hydrocephalus. The associated medical treatment was antibiotics combining third-generation cephalosporins, fluoroquinolone, and metronidazol, with a mean duration of 12 days. Recovery rate was 89%, letality 11%, and after effect rate were 33%. Our results confirm the low frequency of neurosurgical complications related to bacterial meningitis, but it emphasizes the role of an early CT-scan for diagnosis and prognosis.

[Surgical tetanus in Abidjan, Cote d'Ivoire]. / Tétanos à porte d'entrée chirurgicale à Abidjan, Côte d'Ivoire.

OBJECTIVE: To describe the epidemiological and clinical features and the outcome of tetanus with a surgical wound (open fracture, burn, incision, curettage, etc) as the portal of entry. METHODS: Cross-sectional analysis of records of patients hospitalized in the department of infectious and tropical diseases in Abidjan for surgical tetanus from 2003 to 2008. RESULTS: During the 6-year study period, 29 cases were identified. They accounted for 11% of all tetanus cases admitted to the hospital: 8% from 2003 through 2006 and 14% in 2007 and 2008. The patients' average age was 36 years (range: 11-72). Most cases (86%) involved recent surgery, in both public (51%) and private (49%) health facilities. All patients had generalized tetanus at admission, and 24 (86%) paroxysms. Moderate forms predominated (69%). The lethality of tetanus in these surgical wound cases was 45%. The characteristics statistically associated with death were: age >44 years, time of hospitalization >4 days, the presence of paroxysms, and a Dakar prognosis score ≥4. CONCLUSION: The severity of surgical tetanus remains a concern for practitioners. Its high prevalence in recent years demonstrates the need to increase surgeons' awareness of tetanus prevention.

[Human rabies in Abidjan (Côte d'Ivoire): recent cases]. / Rage humaine à Abidjan (Côte d'Ivoire): nouvelles observations.

OBJECTIVE: To present epidemiological and clinical aspects of human rabies in a hospital center. METHOD: We analyzed medical records of cases of rabies in humans treated at the infectious disease department of the Treichville University Hospital Center from January 2005 through December 2009. RESULTS: Seven cases of human rabies were reported during those five years, four in teenagers and three in adults. Five of the cases involved bites by stray dogs whose vaccine status was unknown. No patient had had a pre-exposure prophylactic vaccination, and only four post-exposure prophylaxis, all incomplete. All of the patients developed furious rabies and fever 21 to 96 days (mean: 47.7) after the dog bite, when the wounds had healed and scars formed. Death occurred 4 to 10 days after the onset of symptoms (mean: 4.7). Relatives refused autopsies in all cases. CONCLUSION: It is indispensable to increase population awareness of prevention by vaccination against human rabies, reduce the population of stray dogs, and promote mass vaccination of dogs in the Ivory Coast.

Cryptoccocal meningitis and HIV in the era of HAART in Côte d'Ivoire.

OBJECTIVE: The authors had for aim to describe the management of cryptococcal meningitis in HIV infected adults, in Ivory Coast. PATIENTS AND METHODS: A retrospective study was made from January 1, 2005 to December 31, 2008 on the files of consecutive hospitalized patients presenting with cryptococcal meningitis, at the Treichville University Hospital, Infectious and tropical diseases department (Abidjan). The socio-demographic, clinical, and biological aspects as well as the outcome were analyzed. RESULTS: Eighty patients presenting with cryptococcal meningitis, (2.6% of hospitalized patients) were included: 41 men (51.25%) and 39 women (48.75%); mean age: 40 years (range 26 to 58 years). The delay before consultation was 5.4 days, range 2-12 days). The mains symptoms were headache (83.7%), fever (63.7%), and consciousness disorders (60%). Meningo-encephalitis accounted for 75% of the clinical presentations; 54 patients (67.5%) were naive of antiretroviral treatment (mean CD4: 45/mm(3) (range 5-103/mm(3)), while 26 (32.5%) had received antiretrovirals before presenting with cryptococcal meningitis (Nadir CD4=81/mm(3)). Amphotericin B relayed by fluconazole was prescribed to 86.2% of the patients, associated with a therapeutic lumbar puncture for 30 patients. The death rate was 41.2%. CONCLUSION: In spite of antiretroviral treatment availability in Ivory Coast, cryptococcal meningitis remains frequent with a high death rate. This study stresses the importance of early management to improve the prognosis.

[Efficiency and safety of antiretroviral treatment among the elderly in Abidjan]. / Efficacite et tolerance du traitement antiretroviral chez les sujets ages a Abidjan.

OBJECTIVE: To evaluate the efficacy of antiretroviral treatment in elderly people followed at the Unit for Infectious and Tropical Diseases at the University Hospital in Abidjan. MATERIAL AND METHODS: We performed a retrospective descriptive study of the files of people aged at least 60 years, infected by HIV who were treated and followed-up in the Unit between 1 January 1999 and 31 December 2006. We analysed sociodemographic (age, sex), clinical (weight, Karnofsky scale, CDC, opportunistic infections), biological (HIV, CD4, haemogram, glycaemia, creatininaemia, transaminasaemia) and therapeutic (antiretroviral regimens, evolution, side-effects) parameters. The efficacy of treatment was evaluated as the percentage of patients with < 200 CD4/ml, and its safety was based on deleterious effects. RESULTS: We studied 62 patients (44 men, 18 women), of whom 13 had been treated (21%), 46 had not been treated (74.2%) and 48 (77.4%) were undergoing chemoprophy-laxis with cotrimoxazole. Most were infected with HIV1 (93.6%), 3.2% with HIV2 and 3.2% with both HIV1 and HIV2. The majority (93.3%) was symptomatic, and 67.8% had AIDS. During 34 months of follow-up, 48 patients (77.4%) received first-line treatment, 13 (21%) received second-line and only one patient (1.6%) had third-line treatment. The percentage of patients with more than 200 CD4/ml increased from 20% at baseline to 36% at 6 months and 39% at 12 months. The main clinical side-effect was peripheral neuropathy (30.5%), and the main biological effect was hypertransaminasaemia > 2N (32.3%). The median rate of loss to follow-up was 17.7%, and two patients (3.2%) died. CONCLUSION: Antiretroviral treatment is effective in the elderly, with few biological disorders. A prospective study of a larger sample would elucidate the differences from younger people in the efficacy of such treatment.

Tobacco use and its determinants in HIV-infected patients on antiretroviral therapy in West African countries.

BACKGROUND: Tobacco smoking is common in human immunodeficiency virus (HIV) infected patients from industrialised countries. In West Africa, few data concerning tobacco consumption exist. METHODS: A cross-sectional survey of the International Epidemiological Database to Evaluate AIDS (IeDEA) network in West Africa was conducted. Health workers administered a questionnaire assessing tobacco and cannabis consumption among patients receiving antiretroviral treatment. Regular smokers were defined as current smokers who smoked >1 cigarette per day for >or=1 year. RESULTS: Overall, 2920 patients were enrolled in three countries. The prevalence of ever smokers and regular smokers were respectively 46.2% (95%CI 42.8-49.5) and 15.6% (95%CI 13.2-18.0) in men and 3.7% (95%CI 2.9-4.5) and 0.6% (95%CI 0.3-0.9) in women. Regular smoking was associated with being from Côte d'Ivoire or Mali compared to Benin (OR 4.6, 95%CI 2.9-7.3 and 7.7, 95%CI 4.4-13.6), severely impaired immunological status at highly active antiretroviral treatment initiation (OR 1.5, 95%CI 1.1-2.2) and history of tuberculosis (TB; OR 1.8, 95%CI 1.1-3.0). CONCLUSION: There are marked differences in smoking prevalence among these West African countries. This survey approach also provides proof of the association between cigarette smoking and TB in HIV-infected patients, a major public health issue in this part of the world.
