    Effect of maternal Helicobacter Pylori infection on birth weight in an urban community in Uganda
    (BMC pregnancy and childbirth, 2016) Wanyama, Ronald; Kagawa, Mike N.; Opio, Kenneth C.; Baingana, Rhona K.
    Helicobacter pylori, a widespread infection particularly in developing countries has been associated with many adverse effects during pregnancy including hyperemesis gravidarum, neural tube defects in newborns, intrauterine fetal growth restriction and miscarriage. We sought to document the effects of H. pylori infection on birth weight in a low-income setting in Kampala, Uganda. Methods: This was a prospective cohort study conducted in Kampala between May 2012 and May 2013. The participants were H. pylori positive and H. pylori negative HIV negative primigravidae and secundigravidae. Recruitment was at ≤18 gestation weeks and follow up assessments were carried out at 26 and 36 gestation weeks and soon after delivery. H. pylori infection was determined using H. pylori stool antigen test. Maternal weight and height were measured, and body mass index (BMI) and gestational weight gain were calculated. Only term and live babies were considered. Low birth weight (LBW) was defined as a birth weight of <2500 gram. Results: A total of 221 participants were enrolled with mean ± standard deviation (SD) age of 20.9 ± 2.7 years. The mean ± SD gestation age at delivery was 39.4 ± 1.0 weeks. Primigravidae were 61.5 % (n = 188) and 52.9 % (n=117) of the participants were positive for H. pylori infection. Low pre-pregnancy BMI (<18.5 kg/m2) was recorded in 14.6 % (n = 28) while 38 % (n = 73) had a height <156 cm at recruitment. Of the infants born to the participants, 13.6 % (n = 26) had low birth weight (<2500 gram). Independent predictors for LBW were the mother being positive for H. pylori infection (odds ratio, OR, 3.6, 95 % CI 1.1 – 11.5; P = 0.031) maternal height at recruitment <156 cm (OR 3.4, 95 % CI 1.4–8.2; P = 0.008) and maternal weight gain rates <0.3 kg/week during the 2nd and 3rd trimesters (OR 3.8, 95 % CI 1.0–14.1; P = 0.044). Conclusion: H. pylori infection is associated with LBW among primigravidae and secundigravidae in Kampala, Uganda.

    The spectrum of liver diseases in HIV infected individuals at an HIV treatment clinic in Kampala, Uganda
    (African health sciences, 2008) Ocama, Ponsiano; Katwere, Michael; Piloya, Theresa; Feld, Jordan; Opio, Kenneth C.; Kambugu, Andrew; Katabira, Elly; Thomas, David; Colebunders, Robert; Ronald, Allan
    Liver diseases are common in patients with HIV due to viral hepatitis B and C co-infections, opportunistic infections or malignancies, antiretroviral drugs and drugs for opportunistic infections. Objective: To describe the spectrum of liver diseases in HIV-infected patients attending an HIV clinic in Kampala, Uganda. Method: Consecutive patients presenting with jaundice, right upper quadrant pain with fever or malaise, ascites and/or tender hepatomegaly were recruited and underwent investigations to evaluate the cause of their liver disease. Results: Seventy-seven consecutive patients were recruited over an eleven month period. Of these, 23 (30%) had increased transaminases because of nevirapine (NVP) and/or isoniazid (INH) hepatotoxicity. Although 14 (61%) patients with drug-induced liver disease presented with jaundice, all recovered with drug discontinuation. Hepatitis B surface antigen was positive in 11 (15%) patients while anti-hepatitis C antibody was reactive in only 2 (3%). Probable granulomatous hepatitis due to tuberculosis was diagnosed in 7 (9%) patients and all responded to anti-TB therapy. Other diagnoses included alcoholic liver disease, AIDS cholangiopathy, hepatocellular carcinoma, schistosomiasis, haemangioma and hepatic adenoma. Twelve (16%) patients died during follow-up of which 7 (9%) died because of liver disease. Conclusion: Drug history, liver enzyme studies, ultrasound, and hepatitis B and C investigations identified the probable etiology in 60 (78%) of 77 patients with HIV infection presenting with symptoms and/or signs of liver disease.
