ABSTRACT
Introduction The zoonotic infection with Brucella melitensis can be acquired by inges-tion of unpasteurized goat's or sheep's milk. The infection is common in Eastern Mediterranean countries (EMC), but rare in western Europe (6 cases in Switzerland, 2021). When evaluating patients with symptoms of septic arthritis, brucellosis is not the foremost differential diagnosis. How-ever, with the increasing population of people from EMC in western Eu-rope, the incidence may be rising. We present a patient who was initially suspected to suffer from Long-COVID-Syndrome (LCS), which underscores the relevance of this case in a pandemic situation. Methods/Results A 58-year-old male patient was admitted to the emergency department with a painful right knee effusion after a minor trauma. Additionally, he suffered from fatigue, subfebrile temperatures, back pain and myalgias for more than two months. He was suspected to suffer from LCS after a mild COVID-19 three months earlier. The culture of the arthrocentesis (14.400 cells/mul with 61% polynuclear cells) unexpectedly turned positive for B. melitensis. The patient declared that he had been drinking three liters of unpasteurized goat's milk to cure the presumptive LCS. To ensure staff safety, arthroscopic lavage was postponed until brucella-active antibiotics had been administered for at least 24 hours. Surgery was performed under strict infection control measures to avoid generating aerosols. According to Duke, one major (continuous bacteremia over 14 days) and 2 minor criteria (fever, most probably septic embolic gonarthritis) were fulfilled. Therefore, possible endocarditis had to be assumed although transesophageal echocardiography was normal. Antibiotic treatment was escalated to a quadruple regimen (intravenous gentamicin for three weeks;as well as oral doxycycline, trimethoprim/sulfomethoxazole and rifampin for at least 3 months). The clinical recovery - still under treatment - is protracted with slowly improving knee pain and normalizing signs of inflammation. Conclusion Although B. melitensis is a rare pathogen in Switzerland, orthopedic sur-geons, rheumatologists and infectious disease specialists need to be aware of diseases with low incidence and non-specific symptoms espe-cially in times of a global pandemia. A high index of suspicion is needed in patients related to EMC. When brucellosis is confirmed, strict infection control measures to protect staff involved in aerosol generating proce-dures must be adopted.
ABSTRACT
In the light of the Covid-19 pandemic outbreak, and the need-of-the-hour to boost immunity to residents, especially those residing in an arid environment, a comparative study was made on the physical and biochemical properties of dairy milk. This novel study in Kuwait revealed the lesser consumed pseudoruminant camel milk as a better potential source of dietary inclusion and an immune booster over true ruminants-cow's and goat's milk. Analysis using a wide array of instruments determining the physical characteristics in camel's milk (pH, conductivity, specific gravity, moisture, and total solids), biochemical constituents (crude protein (CP), nonprotein (NP), and fat), and inorganic constituents (K-919; Ca-907; Zn-4.2 mg/100 mg) revealed conducive properties that validate immunity to consumers when compared to the regularly used cow's milk (K-841; Ca-776; Zn-2.43 mg/100 mg) and goat's milk (K-914; Ca-849; Zn-2.45 mg/100 mg). Log-transformed results revealed high vitamin C in camel's milk (0.42 mg/100 g), indicating high antioxidant properties compared to those of goat's milk (0.12 mg/100 g) and cow's milk (0.04 mg/100 g). Statistical tests by analysis of variance (ANOVA) revealed significant differences and the correlation coefficient between the three milk samples validating the multiple reasons to use camel's milk over the cow's and goat's milk. Furthermore, this study recommends the consumption of camel's milk due to its low concentrations of contaminants as well, their status below permissible limits in Kuwait, set by global standards over the other sampled milks.
ABSTRACT
The function of Immune control, haematopoiesis, and inflammation all depend on the cytokine Interleukin 6 (IL-6), and higher expression of IL-6 is seen in COVID-19 and other diseases. The immune protein IL-6 activation is dependent on binding interactions with IL-6Rα, mIL-6R, and sIL-6R for its cellular function. Termination of these reaction could benefit for controlling the over-expression in COVID-19 patients and that may arise as inhibitors for controlling COVID-19. Traditionally, the goat milk has been prescribed as medicine in ayurvedic practice and through this work, we have explored the benefits of peptides from goat milk as IL-6 inhibitors, and it have the potential of inhibiting the over expression of IL-6 and control the COVID-19 disease. Computational experiments have shown that goat peptides had strong interactions with IL-6, with higher scoring profiles and energy efficiency ranging from -6.00 kcal/mol to -9.00 kcal/mol in docking score and -39.00 kcal/mol in binding energy. Especially the YLGYLEQLLR, VLVLDTDYK and AMKPWIQPK peptides from goat milk holds better scoring and shows strong interactions were identified as the most potential IL-6 inhibitor candidates in this study. Peptides from Goat proteins, which are capable of binding to the IL-6 receptor with strong binding conformations, have no negative effects on other immune system proteins.
