ABSTRACT

OBJECTIVE: To assess the risk of developing pulmonary tuberculosis (TB) in accordance with prior history of COVID-19 infection. BACKGROUND: Since the advent of the COVID-19 pandemic much discussion has been had on the possible role it might play on global efforts to combat TB; most, focusing on the pandemic's impact on health care systems' capabilities to manage TB cases. Mechanisms have also been proposed by which the COVID-19 infection may directly affect individuals' chance of developing TB infection. Cases have been reported with a history of COVID-19 infection preceding a diagnosis of TB, evidencing its possible role as a risk factor for the disease. METHODS: A case-control study was conducted enrolling patients diagnosed with pulmonary TB in the absence of major risk factors previous history of TB, (HIV) human immunodeficiency virus infection), end-stage renal disease, organ transplants, and use of immunosuppressive agents) for developing TB. Each patient was age and sex matched with one healthy control. Data regarding prior COVID-19 infection, diabetes, and smoking status as well as the use of corticosteroids and Tocilizumab for the treatment of COVID-19 infection was obtained. Bivariate analysis was conducted and variables with a likely association with TB status were entered in a multivariate model. RESULTS: Bivariate analysis demonstrated a significant relationship between prior COVID-19 infection and TB (95% confidence interval = 1.1-22.8, odds ratio [OR] = 5). Among other variables the severity of COVID-19 infection was found to have a likely association with TB status (p = .125). In a multivariate model, prior COVID-19 infection per se, was not found to be significantly associated with TB (p = .12, OR = 4.5). CONCLUSIONS: There seems to be an association between prior history of COVID-19 and a future diagnosis of TB partially linked to the severity of disease. The findings of the current study may serve as a basis for further studies to determine the need for and efficacy of measures to follow-up COVID-19 patients at an increased risk for developing TB.

ABSTRACT

BACKGROUND: Mucormycosis and aspergillosis are angioinvasive infections mainly occurring in immunocompromised patients. However, mixed infection with mucormycosis and aspergillosis in post-COVID-19 patients is rare. In this report, we will report four cases and comprehensively review the published literature on COVID-19 associated mixed infection of aspergillosis and mucormycosis. METHOD: Besides four of our cases, we searched for published articles using PubMed/MEDLINE, Scopus, and Web of Science databases from the beginning of 2020 until October 2023. RESULT: During the COVID-19 pandemic, we analyzed 52 cases (4 from our research and 48 from other studies). The most common underlying disease (59.6%) was diabetes mellitus. However, 19.2% of COVID-19 patients had no underlying condition. Interestingly, rhino-orbital-cerebral mucormycosis featured prominently in India and Iran, while other countries primarily reported a higher prevalence of pulmonary cases. CONCLUSION: In conclusion, this study highlights the presence of mixed aspergillosis and mucormycosis in COVID-19 patients who previously had common underlying diseases or even a healthy immune system. Therefore, managing COVID-19 patients should involve screening serum and respiratory samples using biomarkers to detect superinfections.

ABSTRACT

PURPOSE: To evaluate and compare the ocular surface condition in herpetic interstitial stromal keratitis and neurotrophic ulcer groups and their normal fellow eyes. METHODS: In this observational, cross-sectional case-control study, 85 consecutive patients were included, including 56 cases of treated herpetic interstitial keratitis and 29 patients with neurotrophic ulcers. Fifty-six age- and sex-matched participants were also recruited from a normal population as the control group. We evaluated and scored the subjective and objective measures of dry eye for both eyes of all patients. Then, we compared the score of the groups with one another and also with the control group. The main outcome measures were the discomfort level, visual symptoms of dry eye, conjunctival injection, conjunctival staining, corneal staining, corneal tear signs of dry eye, meibomian gland dysfunction, tear break-up time, Schirmer test score with anesthesia, and tear osmolarity. RESULTS: The normal fellow eye of the herpetic keratitis group had significantly higher discomfort levels (1.4 ± 0.9 vs. 1.3 ± 0.5, P = 0.003), visual symptoms (1.7 ± 0.8 vs. 1.3 ± 0.7, P = 0.002), tear break-up time (8.3 ± 3.2 vs. 12.1 ± 3.3 seconds, P = 0.003), Schirmer test scores (9.2 ± 3.9 vs. 12.9 ± 3 mm, P = 0.04), and tear osmolarity (9.2 ± 3.9 vs. 12.9 ± 3 mm, P = 0.003) in comparison with normal controls. The normal fellow eyes of the neurotrophic ulcer group had significantly worse values for discomfort level (1.9 ± 0.9 vs. 1.3 ± 0.5, P < 0.001), tear break-up time (7.9 ± 4 vs. 12.1 ± 3.3, P = 0.004), Schirmer test score (8.1 ± 3.9 vs. 12.9 ± 3, P = 0.005), and tear osmolarity (295 ± 9.2 vs. 292.7 ± 5.9, P = 0.02) compared with normal controls. CONCLUSIONS: Both eyes of patients with neurotrophic ulcer and interstitial herpetic keratitis have a significantly poorer ocular surface condition compared with that of normal controls.
