Detection of anti-Chlamydia trachomatis antibodies in Patients with Acquired Immune Deficiency Syndrome in Abuja, Nigeria

Chlamydia trachomatis (CT) infections are among the sexually transmitted diseases known to increase the risk for human immunodeficiency virus infection. Serum samples from 34 consenting AIDS patients which attended the Government-approved Antiretroviral Treatment (ART) Facility at the National Institute for Pharmaceutical Research and Development (NIPRD), Abuja between April 2005 and March 2006 were screened by enzyme immunoassay (EIA) for the presence of anti-CT antibodies using ImmunoComb® Chlamydia Bivalent IgG Test kit (Orgenics, Israel). Anti-CT antibodies were detected in ten (29.4%) of the thirty-four patients tested. The detection rate was higher among the females (33.3%) than the males (23.1%). Patients of the age group 31-45 years had the highest detection of anti-C. trachomatis antibodies, followed by those of age group 16-30 years. The result of the present study suggests the presence of anti-CT antibodies in AIDS patients, and reinforces the need for routine screening for anti-CT antibodies as a necessary intervention to reduce the burden of chlamydial diseases and to reduce the risk of HIV and its spread in Nigeria. The outcome of this study also provides justification for the possible inclusion of anti-chlamydial agents in the National AIDS Management Plan to treat associated C.trachomatis infections.

Double-blind, placebo-controlled, randomised cross-over clinical trial of NIPRISAN in patients with Sickle Cell Disorder.

The study was undertaken to determine the safety and efficacy of NIPRISAN, a phytomedicine, developed for the management of patients with Sickle Cell Disorder (SCD). The study design is a placebo-controlled double blind cross-over trial. Eighty-two (82) patients with SCD were recruited and randomised into two groups. An initial 4 month pre-trial study was undertaken to determine the similarity of the groups. The main study was conducted over a twelve-month period with crossover at six months. Safety of the drug was assessed clinically and biochemically. NIPRISAN significantly (P < 0.01) reduced the frequency of SCD crisis associated with severe pains. Acute toxicity to the liver assessed by the activities of liver enzymes, indicate that NIPRISAN is safe. Renal function assessed by the serum levels of creatinine and blood urea nitrogen remained normal. Both the clinical and laboratory results of the present phase IIB (pivot) clinical study suggest that NIPRISAN is a safe and efficacious phytomedicine for the management of patients with Sickle Cell Disorder.
