Global prevalence, mortality, and main characteristics of HIV-associated pneumocystosis: A systematic review and meta-analysis.

The epidemiology of Human Immunodeficiency Virus (HIV)-associated pneumocystosis (HAP) is poorly described on a worldwide scale. We searched related databases between January 2000 and December 2022 for studies reporting HAP. Meta-analysis was performed using StatsDirect (version 2.7.9) and STATA (version 17) according to the random-effects model for DerSimonian and Laird method and metan and metaprop commands, respectively. Twenty-nine studies with 38554 HIV-positive, 79893 HIV-negative, and 4044 HAP populations were included. The pooled prevalence of HAP was 35.4% (95% CI 23.8 to 47.9). In contrast, the pooled prevalence of PCP among HIV-negative patients was 10.16% (95% CI 2 to 25.3). HIV-positive patients are almost 12 times more susceptible to PCP than the HIV-negative population (OR: 11.710; 95% CI: 5.420 to 25.297). The mortality among HAP patients was 52% higher than non-PCP patients (OR 1.522; 95% CI 0.959 to 2.416). HIV-positive men had a 7% higher chance rate for PCP than women (OR 1.073; 95% CI 0.674 to 1.706). Prophylactic (OR: 6.191; 95% CI: 0.945 to 40.545) and antiretroviral therapy (OR 3.356; 95% CI 0.785 to 14.349) were used in HAP patients six and three times more than HIV-positive PCP-negatives, respectively. The control and management strategies should revise and updated by health policy-makers on a worldwide scale. Finally, for better management and understanding of the epidemiology and characteristics of this coinfection, designing further studies is recommended.

Strongyloides stercoralis infection in human immunodeficiency virus-infected patients and related risk factors: A systematic review and meta-analysis.

Strongyloidiasis is caused by nematode infections of the genus Strongyloides, mainly Strongyloides stercoralis, and affects tens of millions of people around the world. S. stercoralis hyperinfection and disseminated strongyloidiasis are unusual but potentially fatal conditions mostly due to Gram-negative bacteremia and sepsis, primarily affecting immunocompromised patients. Infections with immunosuppressive viruses such as human immunodeficiency virus (HIV) and Human T-cell leucemia virus type 1 (HTLV-1) have been reported as risk factors for strongyloidiasis. Hyperinfection syndrome has been described in HIV-positive patients following the use of corticosteroids or during immune reconstitution inflammatory syndrome (IRIS). In this research, we conducted a global systematic review and meta-analysis to assess the seroprevalence and odds ratios (ORs) of S. stercoralis infections in HIV-infected patients. A total of 3,649 records were screened, 164 studies were selected and evaluated in more detail, and 94 studies were included in the meta-analysis. The overall pooled prevalence of S. stercoralis infection in HIV positive patients was 5.1% (CI95%: 4%-6.3%), and a meta-analysis on six studies showed that with a pooled OR of 1.79 (CI95%: 1.18%-2.69%) HIV-positive men are at a higher risk of S. stercoralis infections (p < .0052) compared to HIV positive women.
