Background: Mycobacterium tuberculosis and human immunodeficiency virus (HIV) are known to cause abnormal thyroid function. There is little information on whether HIV infection aggravates alteration of thyroid function in patients with MDRTB. Objectives: This study was carried out to determine if HIV co-infection alters serum levels of thyroid hormones (T3, T4) and thyroid stimulating hormone (TSH) in patients with MDR-TB patients and to find out the frequency of subclinical thyroid dysfunction before the commencement of MDR-TB therapy. Methods: This observational and cross-sectional study involved all the newly admitted patients in MDR-TB Referral Centre, University College Hospital, Ibadan, Nigeria between July 2010 and December 2014. Serum levels of thyroid stimulating hormone (TSH), free thyroxine (fT4) and free triiodothyronine (fT3) were determined using ELISA. Results: Enrolled were 115 patients with MDR-TB, out of which 22 (19.13%) had MDR-TB/HIV co-infection. Sick euthyroid syndrome (SES), subclinical hypothyroidism and subclinical hyperthyroidism were observed in 5 (4.35%), 9 (7.83%) and 2 (1.74%) patients respectively. The median level of TSH was insignificantly higher while the median levels of T3 and T4 were insignificantly lower in patients with MDR-TB/HIV co-infection compared with patients with MDRT-TB only. Conclusion: It could be concluded from this study that patients with MDR-TB/HIV co-infection have a similar thyroid function as patients having MDR-TB without HIV infection before commencement of MDR-TB drug regimen. Also, there is a possibility of subclinical thyroid dysfunction in patients with MDR-TB/HIV co-infection even, before the commencement of MDR-TB therapy.

Background: Cerebro-meningeal pathology is common in human immunodeficiency virus (HIV) infection and the aetiology is often difficult to ascertain with certainty. Objective: To describe the major suspected and identified causes of meningeal or encephalitic syndromes in HIV infection in Libreville, Gabon. Methods: A descriptive study using clinical records of patients hospitalised in the Department of Medicine in the Military Hospital of Libreville (Gabon) between January 2006 and May 2010. Clinical features were evaluated using multivariable logistic regression to evaluate association with the outcome of a clinical improvement or death. Results: The most frequent neurological symptoms were reduced level of consciousness (54.3%), headache (55.2%), motor deficit (38.7%), and convulsions (36.2%). Cerebral toxoplasmosis represented 64.7% of diagnoses, followed by cryptococcal neuromeningitis in 12.9% of cases. Tuberculoma was diagnosed in 4 cases and lymphoma in 2 cases. In 9.5% of cases, no aetiology was determined. Toxoplasmosis treatment led to clinical improvement in 69.3% of cases with suspected cerebral toxoplasmosis. Overall mortality was 39.7%. Conclusion: The diagnosis of neurological conditions in HIV positive patients is difficult, particularly in a low-resource setting. A trial of treatment for toxoplasmosis should be initiated first line with all signs of neurological pathology in a patient infected with HIV.
HIV Disclosure: Parental dilemma in informing HIV infected Children about their HIV Status in Malawi

Background Increasingly many perinatally HIV-infected children are surviving through adolescence and adulthood as a result of improvements in the management of paediatric HIV infection, particularly the increased use of combination therapy. It is usually the parents or guardians of these children who are faced with the task of informing the child living with HIV about his or her positive status. However, many parents—particularly biological parents —find this disclosure process difficult to initiate, and this study explored some of the difficulties that these parents encounter. Objective This study set out to explore potential factors that challenge parents and guardians when informing their perinatally HIV-infected child about the child’s HIV status. Design This was a qualitative narrative study that employed in-depth interviews with parents or guardians of children perinatally infected with HIV. A total of 20 parents and guardians of children who attend the outpatient HIV clinic at the Baylor College of Medicine-Abbott Fund Children’s Clinical Centre of Excellence (COE) in Lilongwe, Malawi were interviewed. Of these, 14 were biological parents and six were guardians. Results Guardians and parents expressed uneasiness and apprehension with the disclosure conversation, whether or not they had already told their child that he or she had HIV. Participants who had not told their children recounted that they had contemplated starting the conversation but could not gather enough courage to follow through with those thoughts. They cited the fear of robbing their child of the happiness of living without the knowledge of being positive, fear of making their own status known to more people, and fear of confrontation or creating enmity with their child as impediments to disclosing their child’s positive HIV status to him or her. Conclusions It is apparent that guardians—more particularly biological parents—of children perinatally infected by HIV find it difficult to inform their children about their children’s HIV status. From this disempowered position, parents dread the disclosure of a positive HIV status to a child as a psychosocial process that has the potential to disturb a family’s previously established equilibrium with threats of stigmatization, marginalization, and parent-child conflict. This calls for strategies that could support parents to make disclosure to the child less challenging.

Background Aerobic endurance is an important aspect of physical fitness that enables individuals living with HIV to endure in the work place as well as in agricultural operations in order to earn a living and improve their quality of life. However, despite high HIV prevalence rates, the aerobic endurance status of young Malawians living with HIV remains unknown. The objective of this study was to determine the difference in VO2max between HIV-negative and HIV-positive individuals in Blantyre, Malawi. Methods Fifty five participants (17 males and 38 females) who have HIV and were not taking antiretroviral medication and 78 HIV-negative participants (45 males and 33 females) performed the Rockport submaximal treadmill exercise test. Measures of body weight, post-exercise heart rate and time to walk one mile were obtained and used to predict VO2max. Comparisons between groups were adjusted for age differences using analysis of covariance (ANCOVA). Results VO2max was significantly lower in HIV-positive subjects [31.1, 28.7 - 33.5mL.kg-1.min-1(mean, 95% CI)] compared with HIV-negative subjects [56.2, 54.3 - 58.1mL.kg-1.min-1]. Conclusion Aerobic endurance was markedly reduced in HIV-positive participants compared with HIV-negative participants. Findings of the current study implicate factors associated with the HIV infection as contributors to a decreased aerobic endurance in people living with HIV.

Some of the secondary findings from the circumcision studies conducted in Africa, are both interesting and difficult to explain. This paper focuses on the finding that uncircumcised men who waited for ten minutes after sexual intercourse and then wiped their penises using a dry cloth, had lower rates of HIV infection compared to those who cleaned using a wet cloth or those who cleaned within three minutes of having intercourse. The paper also focuses on the finding on men who became infected and yet they reported no sexual acts or 100% condom use. Interpretations that have been provided so far in trying to explain these two interesting findings are somewhat inadequate. Because of the inadequate interpretation that has been provided, anti-circumcision lobbyist are presenting the “wait and wipe strategy” as an alternative to circumcision for HIV prevention. In this paper, we argue that waiting for ten minutes and wiping with a dry cloth does not prevent men from becoming infected by HIV. We therefore attempt to present some alternative views.

Background In post-stroke patients, impairment of quality of life (QOL) has been associated with functional impairment, age, anxiety, depression, and fatigue. Good social support, higher education, and better socioeconomic status are associated with better QOL among stroke survivors. In Africa, studies from Nigeria and Tanzania have reported on post-stroke QOL. Aim The aim of this study was to describe QOL more than six months after first-ever stroke in Malawi. Methods This was an interview-based study about a stroke-surviving cohort. Adult patients were interviewed six or twelve months after their first ever stroke. HIV status, modified stroke severity scale (mNIHSS) score, and brain scan results were recorded during the acute phase of stroke. At the time of the interviews, the modified Rankin scale (mRS) was used to assess functional outcome. The interviews applied the Newcastle Stroke-specific Quality of Life Measure (NEWSQOL). All the data were analysed using Statview™: the X2 test compared proportions, Student’s t-test compared means for normally distributed data, and the Kruskal-Wallis test was used for nonparametric data. Results Eighty-one patients were followed up at least six months after the acute stroke. Twenty-five stroke patients (ten women) were interviewed with the NEWSQOL questionnaire. Good functional outcome (lower mRS score) was positively associated with better QOL in the domains of activities of daily living (ADL)/self-care (p = 0.0024) and communication (p = 0.031). Women scored worse in the fatigue (p = 0.0081) and cognition (p = 0.048) domains. Older age was associated with worse QOL in the ADL (p = 0.0122) domain. Seven patients were HIV-seroreactive. HIV infection did not affect post-stroke QOL. Conclusion In Malawi, within specific domains, QOL after stroke appeared to be related to patients’ age, sex, and functional recovery in this small sample of patients.

Background The proportions of women of reproductive age living with the human immunodeficiency virus (HIV) vary between different regions of the world, with significantly higher proportions in sub-Saharan Africa. Family planning is one of the major issues that couples and families affected with HIV must confront. We aimed to assess the cultural and social factors associated with childbearing and family planning knowledge, decisionmaking, and practices among HIV-positive pregnant women attending antenatal clinic at a health centre in Balaka, Malawi. Methods This was a qualitative descriptive study carried out at Kalembo Health Centre in Balaka. A purposive sampling technique was used to select pregnant women enroled in the antiretroviral therapy (ART) programme. A sample size of thirty-five women was decided upon after data saturation. Qualitative inquiry was used during data collection. Data were analysed using systematic text condensation, while numbers and percentages were generated using Microsoft Excel. Results Out of 35 participants, 20 were aged between 25 and 34 years, and 18 had been married at least three times. All 35 women wished to have their own biological child. Factors, reported by participants, that promote childbearing included: the desire to please their husbands, fear of losing their husbands to others if they did not bear children, the knowledge that ART would help prevent their children from acquiring the virus, the desire to prove to others that they can also bear children, and a lack of family planning leading to unplanned pregnancies. Conclusions The factors that lead to pregnancies among women on ART in Balaka ranged from assured safety of the child from HIV, lack of contraception, to other factors related to their partners. The authors recognize and support the freedom for women to become pregnant and bear children, and, in the context of HIV infection, fertility and reproductive services should include a comprehensive approach towards addressing issues of HIV and AIDS and childbearing among infected women.

Background: Tuberculosis is one of the world’s most common causes of death in the era of Human immunodeficiency virus. The purpose of this study was to determine the prevalence and associated factors of TB/HIV co-infection. Methods: Hospital based retrospective studies were conducted among adult HIV-positive patients. Logistic regression method and Chi square test were applied. Results: A total of 571 HIV positive study participants were enrolled. Of these, 158 (27.7%) were found to have pulmonary tuberculosis. Lower baseline CD4 count<200cell/μl, patients who drunk alcohol, patients who were ambulatory at the initiation of ART, patients whose marital status was single were significant predictors for increased risk of tuberculosis in PLWHIV (P <0.05). Non smoker patients, patients in WHO clinical stage I, patients in WHO clinical stage II and ownership of the house had significant protective benefit against risk of TB (P <0.05). Conclusion: The prevalence of TB/HIV co-infection in adults on ART in our study was moderately high. Having advanced clinical status and presence of risk factors were found to be the predicting factors for co-infection. The health office should open TB/HIV co-infection units in the hospitals and health workers should be cautious when a patient has an advanced disease.
