Abstract
BACKGROUND Lung cancer is the second most common cancer worldwide, yet the distribution by histological subtype remains unknown. We aimed to quantify the global, regional, and national burden of lung cancer incidence for the four main subtypes in 185 countries and territories. METHODS In this population-based study, we used data from Cancer Incidence in Five Continents Volume XI and the African Cancer Registry Network to assess the proportions of adenocarcinoma, squamous cell carcinoma, small-cell carcinoma, and large-cell carcinoma among all lung cancers by country, sex, and age group and subsequently applied these data to corresponding national (GLOBOCAN) estimates of lung cancer incidence in 2020. Unspecified morphologies were reallocated to specified subtypes. Age-standardised incidence rates were calculated using the world standard population to compare subtype risks worldwide, adjusted for differences in age composition between populations by country. FINDINGS In 2020, there were an estimated 2 206 771 new cases of lung cancer, with 1 435 943 in males and 770 828 in females worldwide. In males, 560 108 (39%) of all lung cancer cases were adenocarcinoma, 351 807 (25%) were squamous cell carcinoma, 163 862 (11%) were small-cell carcinoma, and 115 322 (8%) were large-cell carcinoma cases. In females, 440 510 (57%) of all lung cancer cases were adenocarcinoma, 91 070 (12%) were squamous cell carcinoma, 68 224 (9%) were small-cell carcinoma, and 49 246 (6%) were large-cell carcinoma cases. Age-standardised incidence rates for adenocarcinoma, squamous cell carcinoma, small-cell carcinoma, and large-cell carcinoma, respectively, were estimated to be 12·4, 7·7, 3·6, and 2·6 per 100 000 person-years in males and 8·3, 1·6, 1·3, and 0·9 per 100 000 person-years in females worldwide. The incidence rates of adenocarcinoma exceeded those of squamous cell carcinoma in 150 of 185 countries in males and in all 185 countries in females. The highest age-standardised incidence rates per 100 000 person-years for adenocarcinoma, squamous cell carcinoma, small-cell carcinoma, and large-cell carcinoma, respectively, for males occurred in eastern Asia (23·5), central and eastern Europe (17·5), western Asia (7·2), and south-eastern Asia (11·0); and for females occurred in eastern Asia (16·0), northern America (5·4), northern America (4·7), and south-eastern Asia (3·4). The incidence of each subtype showed a clear gradient according to the Human Development Index for male and female individuals, with increased rates in high and very high Human Development Index countries. INTERPRETATION Adenocarcinoma has become the most common subtype of lung cancer globally in 2020, with incidence rates in males exceeding those of squamous cell carcinoma in most countries, and in females in all countries. Our findings provide new insights into the nature of the global lung cancer burden and facilitates tailored national preventive actions within each world region. FUNDING None.

Abstract
Ovarian cancer (OC) is one of the commonest cancers of women in sub-Saharan Africa (SSA), although to date no data have been available on time trends in incidence to better understand the disease pattern in the region. We estimate time trends by histological subtype from 12 population-based cancer registries in 11 countries: Kenya (Nairobi), Mauritius, Seychelles, Uganda (Kampala), Congo (Brazzaville), Zimbabwe (Bulawayo and Harare), Cote d'Ivoire (Abidjan), The Gambia, Mali (Bamako), Nigeria (Ibadan) and South Africa (Eastern Cape). The selected registries were those that could provide consistent estimates of the incidence of ovarian cancer and with quality assessment for periods of 10 or more years. A total of 5423 cases of OC were included. Incidence rates have been increasing in all registries except Brazzaville, Congo, where a nonsignificant decline of 1% per year was seen. Statistically significant average annual increases were seen in Mauritius (2.5%), Bamako (5.3%), Ibadan (3.9%) and Eastern Cape (8%). Epithelial ovarian cancer was responsible for the increases observed in all registries. Statistically significant average annual percentage changes (AAPC) for epithelial OC were present in Bamako (AAPC = 5.9%), Ibadan (AAPC = 4.7%) and Eastern Cape (AAPC = 11.0%). Creating awareness among professionals of the growing importance of the disease is surely an important step to improving availability of, and access to, diagnosis and treatment of OC in SSA. Support must be given to the cancer registries to improve the availability of good-quality data on this important cancer.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) plays a major role in the metabolism of folates and homocysteine, which in turn can affect gene expression and ultimately promote the development of breast cancer. Thus, mutations in the MTHFR gene could influence homocysteine, methionine, and S-adenosylmethionine levels and, indirectly, nucleotide levels. Imbalance in methionine and S-adenosylmethionine synthesis affects protein synthesis and methylation. These changes, which affect gene expression, may ultimately promote the development of breast cancer. We therefore hypothesized that such mutations could also play an important role in the occurrence and pathogenesis of breast cancer in a Malian population. In this study, we used the PCR-RFLP technique to identify the different genotypic profiles of the C677T MTHFR polymorphism in 127 breast cancer women and 160 healthy controls. The genotypic distribution of the C677T polymorphism in breast cancer cases was 88.2% for CC, 11.0% for CT, and 0.8% for TT. Healthy controls showed a similar distribution with 90.6% for CC, 8.8% for CT, and 0.6% for TT. We found no statistical association between the C677T polymorphism and breast cancer risk for the codominant models CT and TT (p > 0.05). The same trend was observed when the analysis was extended to other genetic models, including dominant (p = 0.50), recessive (p = 0.87), and additive (p = 0.50) models. The C677T polymorphism of MTHFR gene did not influence the risk of breast cancer in the Malian samples.

Abstract
AIMS To describe the clinical and evolutionary aspects of the primary closure of exstrophy at the CHU Gabriel Touré. MATERIALS AND METHODS This was a retrospective and prospective study carried out from January 2014 to December 2019 in all the children admitted and operated on for bladder exstrophy at the CHU Gabriel Touré. RESULTS We collected 35 cases of exstrophy, ie25 boys and 10 girls. The mean age at diagnosis was 4.8 months. The bladder plate was both normal and budded, ie 28.6% of cases. Plaque infection was found in 45.7%. A malformation was associated in 34.3% of cases. Primary plaque closure was achieved in all of our patients. Postoperative morbidity was 28.6% of cases and mortality 11.4% of cases. CONCLUSION Bladder exstrophy is a rare malformation of the urogenital sphere, its management is complex and its mortality is not null.

Abstract
OBJECTIVES The main objective of this study was to evaluate the effect of CYP2B6 and CYP3A4 polymorphisms on the virological and immunologic responses of HIV patients. A total of 153 HIV-positive patients were enlisted for the study. PATIENTS AND METHODS Viral load and median CD4 T cell counts were evaluated at baseline and month 6 (M6). Samples were identified using TaqMan genotyping assays. RESULTS The AG in CYP2B6 rs2279343 was associated with VLS compared to homozygous AA. In the dominant model, the AG/GG genotypes were associated with VLS compared to the AA genotype. Moreover, in overdominant model, the AG genotype was associated with VLS compared to AA/GG. Regarding immunological response, only the AG in SNP rs2279343 CYP2B6 was associated with an increase in CD4 cell count between baseline and M6. In CYP2B6 rs3745274, the CD4 cell count at M6 was higher than that of baseline for GG carriers and for GT carriers. In CYP3A4 rs2740574, the TC carriers showed a higher median CD4 count at M6 compared to that of the baseline count, as well as for CC carriers. The best genotypes combination associated with CD4 cell count improvement were AA/AG in SNP rs2279343 and GG/GT in SNP rs3745274. CONCLUSION Our findings support the fact that CYP2B6 rs2279343 could help in the prediction of VLS and both SNPs rs3745274 and rs2279343 in CYP2B6 and CYP3A4 rs2740574 were associated with immune recovery in Malian HIV-positive patients.

Abstract
Acute bursa is a medico-surgical emergency because of its many etiologies threatening the functional prognosis of the testes and their appendages. OBJECTIVES Identify the causes of acute bursaries in the child and describe their clinical and therapeutic aspects. MATERIALS AND METHOD This was a retrospective descriptive study from January 1, 2010 to December 31, 2015 on all children aged 0 to 15 years received and treated for acute scholarship in the Pediatric Surgery department at the teaching hospital Gabriel Touré. RESULTS In 6 years, we registered 42 patients, ie a frequency of 1.4% of surgical emergencies. The mean age was 2.98 years (24 days-14 years). Prematurity represented 11.9% of cases. Painful scrotal tumefaction was the main reason for consultation (76.2%), The main aetiologies were HISE (90.5%), scrotal trauma (4.7%), orchi epididymitis (2.4%) and testicular torsion (2.4%). The treatment was surgical in 97.6% of cases. The course after 3 months was simple in 97.6% of cases. CONCLUSION Acute bursa in children is an uncommon condition, especially affecting infants. Strangulated inguino-scrotal hernia was the main aetiology. The diagnosis must be early and the treatment adequate in order to reduce morbidity and mortality.

Abstract
INTRODUCTION The aim of this study was to investigate the contribution of computed tomography (CT) and its degree of concordance with pathological examination in the etiological diagnosis of maxillomandibulartumours. MATERIALS AND METHODS Our study was cross-sectional, retrospective and prospective. It took place over a period of five years and six months and included cases of maxilla-mandibulartumours confirmed by pathological examination after clinical examination and CT scan. Data were collected from medical records, entered and analysed with SPSS 21.0 software. RESULTS Men represented 55.7% of cases with a sex ratio of 1.25. The duration of symptoms on presentation varied from 1 month to 27 years (mean 24.37+/- 48 months). This consultation was motivated in 92.6% of cases by a mandibular swelling. Squamous cell carcinomas were the most common on pathological examination with 34.2% of cases followed by ameloblastomas in 24.2% of cases. There was good agreement between the results of the CT scan and those of the pathological examination (Cohen's Kappa=0.77). CONCLUSION CT remains a reliable tool in the diagnosis of maxillomandibulartumours.

Abstract
Two hundred patients were refereed for advanced cancer to the oncology department of Luxembourg Hospital in Bamako. All these patients reported intense pain (88 %) which was only treated before admission by OMS level 1 analgesics. It clearly shows that cancer pain is undertreated in Malian peripheral sanitary structures. After evaluation of the pain by analog visual and verbal scales patients, the appropriate analgesic drugs such as morphine (OMS level 3) were given. A control of the pain was obtained in all the patients (100 %) with a dramatic improvement in quality of life. This study emphasizes the need for a pain control program at the Malian state level with a basic education of care givers, hospital-centric networks and access to morphine and opioids at the different levels involved in cancer management.

Abstract
Cytochrome P450 enzymes play a central role in the phase I biotransformation process of a wide range of compounds, including xenobiotics, drugs, hormones and vitamins. It is noteworthy that these enzymes are highly polymorphic and, depending on the genetic makeup, an individual may have impaired enzymatic activity. Therefore, the identification of genetic variants in these genes could facilitate the implementation of pharmacogenetic studies and genetic predisposition to multifactorial diseases. We have established the frequencies of CYP2B6 (rs3745274; rs2279343) and CYP3A4 (rs2740574) alleles and genotypes in 209 healthy Malian subjects using TaqMan drug metabolism genotyping assays for allelic discrimination. Allele frequencies were 37% for CYP2B6 rs3745274; 38% for CYP2B6 rs2279343; and 75% for CYP3A4 rs2740574 respectively. Overall, the frequencies observed in Mali are statistically comparable to those reported across Africa except North Africa. The major haplotypes in CYP2B6 rs3745274 and CYP2B6 rs2279343 were represented by GA (60.24%) followed by TG (35.36%). We noted a strong linkage disequilibrium between CYP2B6 rs3745274 and CYP2B6 rs2279343 with D' = 0.91 and r2 = 0.9. The frequencies of the genotypic combinations were 43.5% (GT/AG), 37.3% (GG/AA) and 11.5% (TT/GG) in the combination of CYP2B6-rs3745274 and CYP2B6-rs2279343; 26.8% (GT/CC), 25.4%, (GT/CT), 17.2% and GG/CT in the combination CYP2B6-rs3745274-CYP3A4-rs2740574; 26.8% (AG/CC), 23.9% (AA/CC), 19.1% (AG/CT), and 11% (AA/CT) in the combination CYP2B6-rs2279343-CYP3A4-rs2740574, respectively. The most common triple genotype was GT/AG/CC with 24.9%, followed by GG/AA/CC with 23.9%, GT/AG/CT with 16.7%, and GG/AA/CT with 10%. Our results provide new insights into the distribution of these pharmacogenetically relevant genes in the Malian population. Moreover, these data will be useful for studies of individual genetic variability to drugs and genetic predisposition to diseases.

Abstract
Background The effect of the p.Arg72Pro variant of the P53 gene on the risk of development ofbreast cancer remains variable in populations. However, the use ofstrategies such aspoolingage-matched controls with disease may provide a consistent meta-analysis. Our goal was to perform a meta-analysis in order to assess the association of p.Arg72Pro variant of P53 gene with the risk of breast cancer. Methods Databases such as PubMed, Genetics Medical Literature, Harvard University Library, Web of Science and Genesis Library were used to search articles. Case-control studies with age-matched on breast cancer havingevaluated the genotype frequencies of the TP53 p.Arg72Pro polymorphism were selected. The fixed and random effects (Mantel-Haenszel) were calculated using pooled odds ratio of 95% CI to determine the risk of disease. Inconsistency was calculated to determine heterogeneity among the studies. The publication bias was estimated using the funnel plot. Results Twenty-one publications with 7841 cases and 8876 controls were evaluated in this meta-analysis. Overall, our results suggested that TP53 p.Arg72Pro was associated with the risk of breast cancer for the dominant model (OR = 1.09, 95% CI = 1.02–1.16, P = 0.01) and the additive model (OR = 1.09, 95% CI = 1.01–1.17, P = 0.03), but not for the recessive model (OR = 1.07, 95% CI = 0.97–1.18, P = 0.19). According to the ethnic group analysis, Pro allele was associated with the risk of breast cancer in Caucasians for the dominant model and additive model (P = 0.02), and Africans for the recessive model and additive model (P = 0.03). Conclusions This meta-analysis found a significant association between TP53 p.Arg72Pro polymorphism and the risk of breast cancer. Individuals carrying at least one Pro allele were more likely to have breast cancer than individuals harboring the Arg allele.

Abstract
OBJECTIVES Breast cancer is the most prevalent cancer and the second leading cause of cancer-related deaths among women after cervical cancer in much of sub-Saharan Africa. This study aims to examine the prevalence and sociodemographic-socioeconomic factors associated with breast cancer screening among women of reproductive age in sub-Saharan Africa. DESIGN A weighted population-based cross-sectional study using Demographic and Health Surveys (DHS) data. We used all available data on breast cancer screening from the DHS for four sub-Saharan African countries (Burkina Faso, Ivory Coast, Kenya and Namibia). Breast cancer screening was the outcome of interest for this study. Multivariable Poisson regression was used to identify independent factors associated with breast cancer screening. SETTING Four countries participating in the DHS from 2010 to 2014 with data on breast cancer screening. PARTICIPANTS Women of reproductive age 15-49 years (N=39 646). RESULTS The overall prevalence of breast cancer screening was only 12.9% during the study period, ranging from 5.2% in Ivory Coast to 23.1% in Namibia. Factors associated with breast cancer screening were secondary/higher education with adjusted prevalence ratio (adjusted PR)=2.33 (95% CI: 2.05 to 2.66) compared with no education; older participants, 35-49 years (adjusted PR=1.73, 95% CI : 1.56 to 1.91) compared with younger participants 15-24 years; health insurance coverage (adjusted PR=1.57, 95% CI: 1.47 to 1.68) compared with those with no health insurance and highest socioeconomic status (adjusted PR=1.33, 95% CI : 1.19 to 1.49) compared with lowest socioeconomic status. CONCLUSION Despite high breast cancer mortality rates in sub-Saharan Africa, the prevalence of breast cancer screening is substantially low and varies gradually across countries and in relation to factors such as education, age, health insurance coverage and household wealth index level. These results highlight the need for increased efforts to improve the uptake of breast cancer screening in sub-Saharan Africa.

Abstract
BACKGROUND Pathologists face major challenges in breast cancer diagnostics in sub-Saharan Africa (SSA). The major problems identified as impairing the quality of pathology reports are shortcomings of equipment, organization and insufficiently qualified personnel. In addition, in the context of breast cancer, immunohistochemistry (IHC) needs to be available for the evaluation of biomarkers. In the study presented, we aim to describe the current state of breast cancer pathology in order to highlight the unmet needs. METHODS We obtained information on breast cancer pathology services within population-based cancer registries in SSA. A survey of 20 participating pathology centres was carried out. These centres represent large, rather well-equipped pathologies. The data obtained were related to the known population and breast cancer incidence of the registry areas. RESULTS The responding pathologists served populations of between 30,000 and 1.8 million and the centres surveyed dealt with 10-386 breast cancer cases per year. Time to fixation and formalin fixation time varied from overnight to more than 72 h. Only five centres processed core needle biopsies as a daily routine. Technical problems were common, with 14 centres reporting temporary power outages and 18 centres claiming to own faulty equipment with no access to technical support. Only half of the centres carried out IHC in their own laboratory. For three centres, IHC was only accessible outside of the country and one centre could not obtain any IHC results. A tumour board was established in 13 centres. CONCLUSIONS We conclude that breast cancer pathology services ensuring state-of-the-art therapy are only available in a small fraction of centres in SSA. To overcome these limitations, many of the centres require larger numbers of experienced pathologists and technical staff. Furthermore, equipment maintenance, standardization of processing guidelines and establishment of an IHC service are needed to comply with international standards of breast cancer pathology.

Abstract
Background Breast cancer, the most common tumor in women in Mali and worldwide has been linked to several risk factors, including genetic factors, such as the PIN3 16-bp duplication polymorphism of TP53. The aim of our study was to evaluate the role of the PIN3 16-bp duplication polymorphism in the susceptibility to breast cancer in the Malian population and to perform a meta-analysis to better understand the correlation with data from other populations. Methods We analyzed the PIN3 16-bp duplication polymorphism in blood samples of 60 Malian women with breast cancer and 60 healthy Malian women using PCR. In addition, we performed a meta-analysis of case-control study data from international databases, including Pubmed, Harvard University Library, Genetics Medical Literature Database, Genesis Library and Web of Science. Overall, odds ratio (OR) with 95% CI from fixed and random effects models were determined. Inconsistency was used to assess heterogeneity between studies and publication bias was estimated using the funnel plot. Results In the studied Malian patients, a significant association of PIN3 16-bp duplication polymorphism with breast cancer risk was observed in dominant (A1A2 + A2A2 vs. A1A1: OR = 2.26, CI 95% = 1.08–4.73; P = 0.02) and additive (A2 vs. A1: OR = 1.87, CI 95% = 1.05–3.33; P = 0.03) models, but not in the recessive model (P = 0.38). In the meta-analysis, nineteen (19) articles were included with a total of 6018 disease cases and 4456 controls. Except for the dominant model (P = 0.15), an increased risk of breast cancer was detected with the recessive (OR = 1.46, 95% CI = 1.15–1.85; P = 0.002) and additive (OR = 1.11, 95% CI = 1.02–1.19; P = 0.01) models. Conclusion The case-control study showed that PIN3 16-bp duplication polymorphism of TP53 is a significant risk factor for breast cancer in Malian women. These findings are supported by data from the meta-analysis carried out on different ethnic groups around the world.

Abstract
Breast cancer is the leading cancer diagnosis and second most common cause of cancer deaths in sub-Saharan Africa (SSA). Yet, there are few population-level survival data from Africa and none on the survival differences by stage at diagnosis. Here, we estimate breast cancer survival within SSA by area, stage and country-level human development index (HDI). We obtained data on a random sample of 2,588 breast cancer incident cases, diagnosed in 2008-2015 from 14 population-based cancer registries in 12 countries (Benin, Cote d'Ivoire, Ethiopia, Kenya, Mali, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Uganda and Zimbabwe) through the African Cancer Registry Network. Of these, 2,311 were included for survival analyses. The 1-, 3- and 5-year observed and relative survival (RS) were estimated by registry, stage and country-level HDI. We equally estimated the excess hazards adjusting for potential confounders. Among patients with known stage, 64.9% were diagnosed in late stages, with 18.4% being metastatic at diagnosis. The RS varied by registry, ranging from 21.6%(8.2-39.8) at Year 3 in Bulawayo to 84.5% (70.6-93.5) in Namibia. Patients diagnosed at early stages had a 3-year RS of 78% (71.6-83.3) in contrast to 40.3% (34.9-45.7) at advanced stages (III and IV). The overall RS at Year 1 was 86.1% (84.4-87.6), 65.8% (63.5-68.1) at Year 3 and 59.0% (56.3-61.6) at Year 5. Age at diagnosis was not independently associated with increased mortality risk after adjusting for the effect of stage and country-level HDI. In conclusion, downstaging breast cancer at diagnosis and improving access to quality care could be pivotal in improving breast cancer survival outcomes in Africa.

Abstract
BACKGROUND Breast cancer, the most common cancer among women worldwide, has a high mortality rate in low-income countries. In sub-Saharan Africa, most breast cancer patients are diagnosed with advanced disease. Some studies have quantified the time delay to diagnosis in sub-Saharan Africa, but very few have used qualitative methods to understand barriers leading to delay. This study analyses barriers throughout a breast cancer patient's pathway from symptom recognition to treatment in Mali. METHOD Three focus group discussions were conducted. The model of pathways to treatment was used to structure the results into 4 time intervals: appraisal, help-seeking, diagnosis, and treatment, with a focus on barriers during each interval. RESULTS The main barriers during the appraisal interval were a low level of breast cancer knowledge among women, their families, and medical professionals, and during the help-seeking interval, mistrust in the community health care centers and economic hardship. Barriers during the diagnosis interval were low quality of health care services and lack of social support, and during the pretreatment interval high costs and lack of specialized services. CONCLUSION Multilevel interventions are needed to ensure access, availability, and affordability of a minimum standard of care for breast cancer patients in sub-Saharan Africa.

Abstract
Bilateral gigantomastia is a rare condition, often associated with pregnancy that is characterized by a diffuse enlargement of both breasts. Here we present a case of a late 20s woman in her seven months pregnancy with a bilateral gestational gigantomastia associated with multiple breast lumps. Histological analysis revealed a fibroadenoma. Her prolactin level after caesarean delivery was found particularly high. A significant decrease in breast size was achieved with bromocriptine treatment in conjunction with a bilateral lumpectomy. This case report highlights the diversity of gigantomastia and emphasizes the importance of a tailored, multidisciplinary approach to the diagnosis and treatment of this condition.

Abstract
BACKGROUND Mammary tumors are frequent. Benign tumors are more frequent, and are characterized by a possibility of recurrence or malignant transformation. The aim of this study was to describe the epidemiological and morphological characteristics of breast benign tumors. METHODS The authors have undertaken a retrospective study from January 1998 to December 2003. This study was led in the laboratory of pathology of the National Institute of Public Health, in surgical and gynecological services of Bamako. The study had concerned all benign tumors confirmed by histology. FINDINGS In total, 186 benign tumors were diagnosed over 611 mammary pathologies (30.44%). The average age was 27.1 +/- 11.7 years. Sex ratio was 17.6 in favour of women. The main complaint was feeling a nodule in the breast (91.9%). The most affected breast was the right side (50.8%). Tumor sizes were variable, and the color changed through white to yellow. Histological aspects were: fibroadenoma (72%), lipoma (8.6%), tubular adenoma (5.9%), papilloma (5.4%), lactating adenoma (3.8%), phyllodes tumor (3.8%), and syringomatous tumor (0.5%). CONCLUSION Benign tumors are frequent in mammary pathology. The patients need a follow-up because of the recurrence or the malignant transformation of these tumors.

Abstract
The benign prostate tumours are dominated by prostatic adenomyoma. They are the first uro-genital pathology worldwide. The objective of this work is to describe the anatomo-pathological, clinical and radiological aspects of benign prostate tumours in Mali. It is a retrospective study which was conducted in Bamako (Mali) form January 1998 to December 2003. It has involved 759 patients who had histological confirmed prostate adenoma in the Department of Urology in Point G University Hospital. The patients were classified according to age, the clinical exam, the rate of prostate specific antigen (PSA), the sonogram, the macro and microscopic exam. The average age of the patients is 75.5 years. The apical part of the prostate is the area mostly involved. The adenomyoma is the most frequent histological type (98% of the cases). A very clear radiological and macroscopic disparity was noticed. "The night pollakiuria" was the primarily clinical sign in all patients; the prostate specific antigen (PSA) is high among more than 80%.

Abstract
From February 1992 until June 1994, all patients with histologically proven leprosy examined at the Leprology Unit of the Institut Marchoux in Bamako, Mali, were screened for HIV serology. In total, 740 leprosy patients have been tested; 553 known, previously treated leprosy cases and 187 new cases, mainly self-reporting and referred cases. The global seroprevalence in the sample was 1.5% (11/740), and increased from 1.3% in 1992 to 3.1% in 1994. HIV seroprevalence was higher in paucibacillary (PB) than in multibacillary (MB) cases (3.8% versus 0.8%, p < 0.05), and was slightly higher in new cases than in known, already treated cases (2.1% versus 1.3%), although not significantly. Among the 553 known, already treated leprosy patients, 1 out of 7 HIV-seropositive patients relapsed, as opposed to 34 out of 546 HIV-seronegative cases (14.2% versus 6.2%, p = 0.36). Among the new cases, none of the 37 patients with reaction and/or neuritis was HIV positive. In known, treated leprosy cases, there was no difference in the frequency of reactions and/or neuritis between HIV-positive and HIV-negative cases. Migration in a neighboring country appeared to be a risk factor for HIV seropositivity in our sample (chi 2 = 4.5, p = 0.04). In order to estimate the association of HIV with leprosy as compared to the general population, a control group of blood donors was set up, matched for age and sex. There was, however, no difference in HIV seroprevalence between the control group (9/735, 1.2%) and the leprosy group (1.5%). Although leprosy patients recruited for this study constitute a highly selected sample, it appears that HIV infection has little effect on leprosy, particularly on the PB/MB ratio, leprosy reactions and neuritis, but there is a suggestion the HIV infection might be associated with increased frequency of relapse.
