Attitudes Toward Transplantation in U.K. Muslim Indo-Asians in West London

The worldwide shortage of organs for transplantation makes it important to understand why some oppose donation. Attitudes vary with religion and ethnicity. Accordingly, we undertook a qualitative study of the attitudes of 141 U.K. Muslim Indo-Asians to organ donation. Participants were observed, focus group discussions held and in-depth individual interviews conducted. We identified a high level of alienation from the health care system in general. With respect to organ donation in particular, its importance was generally discounted, often in deference to authority figures within the community who appeared negatively disposed. The culture-specific issues arguing against donation included a sense of the sacredness of the body, a fatalistic approach to illness, a belief that organs took on an independent role as 'witnesses' to an individual's life on Judgement Day and an anxiety that the donor would have no control of the probity of the recipient of an organ. We believe these data suggest a need to improve in a culturally sensitive fashion the provision of health information provided to this community.     

Right atrial myxoma presenting as post partum ascites and fever of unknown origin.

A case is reported of right atrial myxoma presenting clinically as ascites and fever of unknown origin. An extensive work-up, including laboratory investigations, X-ray imaging, laparoscopy and laparotomy, failed to explain the clinical picture which was manifested post partum. Echocardiography was diagnostic and led to the curative treatment of surgical resection.

Pattern and predictors of weight gain during pregnancy among HIV-1-infected women from Tanzania

Progression of HIV disease is often accompanied by weight loss and wasting. Gestational weight gain is a strong determinant of maternal and neonatal outcomes; however, the pattern and predictors of weight gain during pregnancy among HIV-positive women are unknown. We obtained monthly anthropometric measurements in a cohort of 957 pregnant women from Tanzania who were HIV infected. We estimated the weekly rate of weight gain at various points during the second and third trimesters of pregnancy and computed rate differences between levels of sociodemographic, nutritional, immunologic, and parasitic variables at the first prenatal visit. The change in mid-upper arm circumference (MUAC) from baseline to delivery was also examined. The rate of weight gain decreased progressively during pregnancy. There was an average decline of 1 cm in MUAC between weeks 12 and 38. Lower level of education and helminthic infections at first visit were associated with decreased adjusted rates of weight gain during the third trimester. High baseline MUAC, not contributing to household income, lower serum retinol and selenium concentrations, advanced clinical stage of HIV disease, and malaria infection were related to decreased rates of weight gain during the second trimester. Low baseline CD4 T-cell counts were related to a poorer pattern of weight gain throughout pregnancy. Prevention and treatment of parasitic infections and improvement of nutritional status are likely to enhance the pattern of gestational weight gain among HIV-infected women.     

Wasting during pregnancy increases the risk of mother-to-child HIV-1 transmission

OBJECTIVES: To examine whether wasting during pregnancy, as measured by weight loss and low weight gain, is associated with increased mother-to-child transmission (MTCT) of HIV-1. METHODS: This was a cohort study in Dar es Salaam, Tanzania, among 957 HIV-1-infected pregnant women. Weight was measured at the first prenatal visit and every month thereafter until delivery. Weight loss was defined as a weekly rate of weight gain 0 and /=167 g/wk, weight loss during pregnancy was related to higher risk of intrauterine MTCT (adjusted relative risk [RR] = 2.32, 95% CI = 1.23-4.36, P = 0.009), HIV positive at birth or fetal death (RR = 2.13, 95% CI = 1.40-3.24, P = 0.0004), and HIV positive at birth or early neonatal death (RR = 1.96, 95% CI = 1.26-3.07, P = 0.003). The rate of weight gain during the 3rd trimester was inversely related to the risk of intrapartum/early breast-feeding transmission (adjusted P value, test for trend = 0.05). CONCLUSIONS: Weight loss during pregnancy increases the risk of early MTCT. Identifying causes of wasting during pregnancy may provide clues for new strategies to prevent MTCT.

IL-10 and IL-12p40 in Egyptian patients with HCV-related chronic liver disease

Hepatitis C virus (HCV) is the leading cause of chronic liver disease worldwide with a prevalence of approximately 14% in Egypt. IL-10 is a cytokine produced by Th2 cells. It down-regulates the proinflammatory response and modulates hepatic fibrogenesis. IL-12 is produced by antigen presenting cells. It promotes Th1 cell response and has many antiviral properties. Data concerning the Th-1/Th-2 balance in chronic hepatitis C (CH-C) are rather conflicting. Using ELISA, we assessed serum IL-10 and IL-12p40 levels in 66 Egyptian patients with HCV-related liver illness (CH-C, cirrhosis, and HCC), and their relationship to disease activity. Our results showed that spontaneous IL-10 was undetectable in patients with CH-C, HCC or controls. Only 5/22 (23%) of patients with cirrhosis showed detectable levels of IL-10. IL-12p40 was elevated in the patient groups compared to controls (p= 0.01, p= 0.01, p= 0.05 in CH-C, cirrhosis and HCC, respectively). The presence of IL-12p40 was associated with HCV level of viremia and serum AST. Serum ALT level was significantly associated with the level of IL-12p40. IL-12p40 was unrelated to liver histology or fibrosis. We concluded that in the Egyptian patients an augmentation of IL-12p40 and a suppression of IL-10 are both found. Whether this pattern is related to HCV genotype 4, or to the presence of schistosomiasis would need to be further investigated.     

HIV co-infection, CD4 cell counts and clinical correlates of bacillary density in pulmonary tuberculosis.

BACKGROUND: Sputum microscopy for acid-fast bacilli (AFB) is the commonest diagnostic method for pulmonary tuberculosis (PTB) in developing countries. The method is reported to be less sensitive in human immunodeficiency virus (HIV) positive compared to negative patients. We determined the bacillary density in sputum of smear-positive PTB patients and related it to the patients' HIV status, CD4 cell count, clinical and demographic characteristics. METHODS: Three sputum samples per patient were examined using microscopy before initiating therapy. The AFB density was graded according to World Health Organization recommendations. The smear with the highest density was used. High bacillary density was defined as >10 AFB/field. HIV status and CD4 cell count were determined according to the national guidelines. RESULTS: Of 844 patients, 433 (51.3%) were HIV-positive. High bacillary density was significantly less common among HIV-positive (39.0%) than -negative (75.7%) patients (prevalence ratio 0.52; 95%CI 0.45-0.59, P < 0.0001). Among HIV-positive patients, the proportion of those with high bacillary density increased progressively with CD4 cell counts (P = 0.003). CONCLUSION: HIV is associated with lower AFB concentration in sputum. The AFB density falls with falling CD4 cell count. Microscopy for AFB in sputum may be less sensitive in diagnosing PTB when HIV infection is present, especially in severely immunocompromised patients.
