|Abstract: ||BACKGROUND: Squamous cell carcinoma of the conjunctiva (SCCC) is associated with HIV-related immunosuppression, but human
papillomavirus virus (HPV) is also suspected to have a role. We carried out a case–control study to assess the role of cutaneous and
mucosal HPV types in SCCC, conjunctival dysplasia, and their combination (SCCC/dysplasia) in Uganda.
METHODS: We compared HPV prevalence in frozen biopsies from 94 SCCC cases (79 of whom were found to be HIV-positive), 39
dysplasia cases (34 HIV-positive), and 285 hospital controls (128 HIV-positive) having other eye conditions that required surgery.
Highly sensitive PCR assays that detect 75 HPV types were used. Odds ratios (ORs) and 95% confidence intervals (CIs) were
computed, adjusting for, or stratifying by age, sex, and HIV status.
RESULTS: Cutaneous HPV types were detected in 45% of SCCC cases, 41% of dysplasia cases and 11% of controls. Human
papillomavirus virus 5 and 8 were the most common types in SCCC, and most often occurred in combination with other types.
Associations were observed between SCCC/dysplasia and detection of both single (OR¼2.3; 1.2–4.4) and multiple (OR¼18.3;
6.2–54.4) cutaneous HPV types, and were chiefly based on findings in HIV-positive patients. Cutaneous HPV infections were rarely
observed among HIV-negative patients and the association with SCCC/dysplasia was not significant (OR¼2.4; 0.6–9.6) among them.
Squamous cell carcinoma of the conjunctiva/dysplasia risk and mucosal HPV types were not associated in either HIV-positive or
CONCLUSIONS: We detected cutaneous HPV types in nearly half of SCCC/dysplasia cases and often multiple types (HPV5 and 8 being
most common). The role of HIV (confounder or strong enhancer of cutaneous HPV carcinogenicity) is still uncertain.|
