We report a rare case of third-degree AV block caused by disseminated gonococcal infection (DGI). Rates of <i>Neisseria gonorrhoeae</i> are increasing, and DGI remains an important but often under-recognised complication. While DGI typically presents with tenosynovitis, polyarthralgia, and skin lesions - cardiac involvement is uncommon. A 36-year-old cis-male who has sex with men presented with polyarthralgia, tenosynovitis, maculopapular rash, and exertional dyspnoea. Electrocardiogram (ECG) demonstrated third-degree AV block. Mucosal swabs were positive for <i>N. gonorrhoeae</i> at both rectal <i>and</i> pharyngeal sites, though blood cultures were likely negative due to prior antibiotic usage before obtaining cultures. Cardiac imaging showed no structural abnormality or evidence of endocarditis. In the absence of an alternative cause, a diagnosis of presumptive DGI was made. After treatment with intravenous ceftriaxone for seven days, cardiac conduction normalised. Follow-up ECG and cardiac magnetic resonance imaging (MRI) at later time points confirmed complete recovery.

Emerging evidence suggests a higher prevalence among people living with HIV (PWHIV), though comprehensive studies are lacking.

This study aimed to determine the prevalence of RLS in a Greek PWHIV population and identify associated demographic, clinical and laboratory risk factors.MethodsThis was a cross-sectional study of 194 PWHIV and 200 non-HIV controls. Data were collected via clinical interviews, validated questionnaires and medical records. We assessed RLS prevalence, clinical characteristics, sleep quality and psychological distress. Statistical analysis included Mann-Whitney U tests, Chi-square tests, and a stepwise logistic regression model to identify independent predictors of RLS.ResultsRLS prevalence was significantly higher in the PWHIV group (31%; 95% CI: 25.3-38.3%) compared to controls (15%; 95% CI: 10.2-20.2%, p < 0.001). In PWHIV, RLS was associated with shorter duration of HIV/HAART, lower CD4 cell counts at diagnosis and currently, and detectable viral load. Detectable viral load was the strongest independent predictor of RLS (OR 15.49, p < 0.001). RLS was also independently associated with poor sleep quality (OR 15.48), anxiety (OR 5.18), and depression (OR 9.22).ConclusionsRLS is a prevalent comorbidity in Greek PWHIV, strongly associated with active viral replication and a state of advanced immunosuppression.

After consultation with perinatal HIV experts, she initiated a long-acting injectable regimen combining lenacapavir (927 mg subcutaneous every 6 months) and cabotegravir/rilpivirine (600/900 mg intramuscular every 2 months).
