Penicilliosis is a systemic fungal infection caused by Penicillium marneffei. The infection is most commonly seen in Southeast Asia, Southern China, Hong Kong, and Taiwan. It is rarely seen among individuals of African descent. Here, we report a case of penicilliosis in an African man from Namibia who was studying in Malaysia. He presented with multiple umbilicated papules associated with cough, fever, loss of appetite, and weight. He also had urethral discharge and admitted to unprotected sexual intercourse with multiple partners. Histopathological examination of a skin papule showed the presence of multiple 2 to 4 microm intracellular yeast cells. Culture of the papule revealed Penicillium marneffei. The serology for human immunodeficiency virus (HIV) was positive. This case illustrates the need to recognize penicilliosis in any individuals staying or travelling to Southeast Asia and the need to look for underlying HIV infection in adults with umbilicated papules.
First-void urine samples collected from sexually transmitted diseases (STD) clinic patients were examined by a nested polymerase chain reaction (PCR) and a commercial enzyme immunoassay (IDEIA Chlamydia) for the diagnosis of Chlamydia trachomatis urethritis or cervicitis. The primers for the PCR amplified a target in the major outer membrane protein (MOMP) gene in C trachomatis while the IDEIA detected genus-specific chlamydial lipopolysaccharide. Discrepant results were resolved by retesting urine specimens with a second (plasmid-based) PCR and taking urethral or endocervical swab results into consideration. For 231 men (chlamydial prevalence 20.4%), the sensitivity, specificity, positive and negative predictive values were 59.6%, 99.5%, 96.6% and 90.6% for urine IDEIA, 68.1%, 99.5%, 97% and 92.4% for urethral swab IDEIA and 97.9%, 99.5%, 97.9% and 99.5% for urine PCR. The corresponding rates for 66 women (chlamydial prevalence 54.6%) were 19.4%, 100%, 100% and 50.8% for urine IDEIA, 86.1%, 96.7%, 96.9% and 85.3% for endocervical swab IDEIA and 91.7%, 93.3%, 94.3% and 90.3% for urine PCR. Hence, in a high prevalence population, the urine IDEIA was a suitable alternative to the male urethral swab IDEIA but significantly less sensitive than the endocervical swab IDEIA. The urine PCR was, however, much more sensitive than the urine IDEIA for both men and women and could replace the endocervical swab IDEIA for the diagnosis of chlamydial cervicitis.
