: The inception of the COVID-19 pandemic has jeopardized humanity with markedly dampening of worldwide resources. The viral infection may present with varying signs and symptoms, imitating pneumonia and seasonal flu. With a gradual course, this may progress and result in the deadliest state of acute respiratory distress syndrome (ARDS) and acute lung injury (ALI). Moreover, following recovery from the severe brunt of COVID-19 infection, interstitial portions of alveoli have been found to undergo residual scarring and further to have compromised air exchange. Such alterations in the lung microenvironment and associated systemic manifestations have been recognized to occur due to the extensive release of cytokines. The mortality rate increases with advancing age and in individuals with underlying co-morbidity. Presently, there is no availability of specific antiviral therapy or any other definitive modality to counter this progressive worsening. However, we believe principles and advancing cell-based therapy may prove fruitful in subjugating such reported worsening in these patients. This article reviews eminent knowledge and relevant advancements about the amelioration of lung damage due to COVID-19 infection using adipose tissue-derived – total stromal fraction (TSF).

Parenchymal Damage

A systemic infection due to community-acquired methicillin-resistant Staphylococcus aureus occurred in a hospital-naive 17-year-old girl with no history of soft-tissue infection. Although the initial signs and symptoms were indolent, systemic manifestations occurred, including extensive lung parenchymal damage and acute respiratory distress syndrome. The patient required long-term mechanical ventilation and was given linezolid for 8 weeks. Blood cultures eventually became negative for the staphylococci, and the patient was discharged to a rehabilitation facility. A probable source of the infection was the patient’s self-cutting and self-piercing.

Alpha Galactosidase

: Fabry disease is an X-linked disorder of glycosphingolipid metabolism that results in progressive accumulation of neutral glycosphingolipids, predominantly globotriaosylsphingosine (Gb3) in lysosomes, as well as other cellular compartments of several tissues, causing multi-organ manifestations (acroparesthesias, hypohidrosis, angiokeratomas, signs and symptoms of cardiac, renal, cerebrovascular involvement). Pathogenic mutations lead to a deficiency of the lysosomal enzyme alpha-galactosidase A (GLA). In the presence of high clinical suspicion, a careful physical examination and specific laboratory tests are required. Finally, the diagnosis of Fabry’s disease is confirmed by the demonstration of the absence of or reduced alpha-galactosidase A enzyme activity in hemizygous men and gene typing in heterozygous females. Measurement of the biomarkers Gb3 and Lyso Gb3 in biological specimens may facilitate diagnosis. The current treatment of Anderson-Fabry disease is represented by enzyme replacement therapy (ERT) and oral pharmacological chaperone. Future treatments are based on new strategic approaches such as stem cell-based therapy, pharmacological approaches chaperones, mRNA therapy, and viral gene therapy. : This review outlines the current therapeutic approaches and emerging treatment strategies for Anderson-Fabry disease.

Hypoxic Training

COVID-19, a disease caused by the novel coronavirus SARS-CoV-2, primarily affects lung tissue and disrupts gas exchange, leading to acute respiratory distress syndrome, systemic hypoxia, and lung damage. The search for methods of prevention and rehabilitation, especially after suffering from pneumonia caused by COVID-19, is on the agenda. This article discusses the possibilities of the interval hypoxic training (IHT) method for preventing infections by initiating nitric oxide production in the body. One of the main effects of IHT is the balanced stimulation of nitric oxide (NO) secretion. Over the past two decades, there has been an increasing interest in the function of nitric oxide (NO) in the human body. Nitric oxide plays a key role in maintaining normal vascular function and regulating inflammatory processes, including those leading to lung damage and the development of acute respiratory distress syndrome (ARDS). Our immune system destroys bacteria and viruses by oxidative burst, i.e. when oxygen accumulates inside the cell. This process also involves nitric oxide, a signaling molecule that has an antibacterial and antiviral effect, as well as regulates vascular tone and affects the permeability of the cell wall. Interval hypoxytherapy enhances endogenous oxidative protection and increases the amount of nitric oxide, thus allowing the body’s cells to resist infection more effectively. Mitochondrial NOS induction and mitochondrial NO synthesis increase under the action of pathogenic factors on the cell. By modulating the activity of mtNOS and the synthesis of mitochondrial NO, it is possible to increase the resistance to hypoxic effects. Interval hypo-hyperoxic training as an effective non-specific method of increasing the body’s defenses is indispensable not only in the prevention of viral infection, but also in rehabilitation after viral pneumonia, as well as as a method that reduces the severity of viral infection in the event of infection.

Polyarticular Disease

Eight of 70 children with juvenile rheumatoid arthritis have developed iridocyclitis. This complication occurred more frequently in patients with monoarticular and pauciarticular disease (29%) than in patients with polyarticular disease (2%). Seven of eight patients with iridocyclitis have monoarticular or pauciarticular disease; none has had prominent systemic manifestations or evidence of ankylosing spondylitis. Iridocyclitis preceded joint manifestations in two of the patients and followed arthritis by 1 to 10 years in six of the patients. Activity of iridocyclitis and arthritis seemed unrelated; four patients developed iridocyclitis while arthritis was inactive. In seven children iridocyclitis began insidiously without acute symptoms. Eye involvement has remained unilateral in six patients. Six children have had significant decrease in visual acuity, and six continue to have active ocular inflammation despite therapy. Iridocyclitis is potentially a major cause of disability in juvenile rheumatoid arthritis. Early signs and symptoms may be minimal. Patients at risk are those with limited forms of joint disease. Early detection and therapy are crucial for prevention of permanent ocular damage. Careful eye examination should be a routine part of physical examination of children with rheumatoid arthritis, and periodic slit lamp examinations should be performed even when arthritis is in remission.

Immunomodulatory Therapies

Abstract Severe acute respiratory syndrome coronavirus 2 is associated with higher concentrations of proinflammatory cytokines that lead to lung damage, respiratory failure, and resultant increased mortality. Immunomodulatory therapy has the potential to inhibit cytokines and quell the immune dysregulation. Controversial data found improved oxygenation after treatment with tocilizumab, an interleukin-6 inhibitor, sparking a wave of interest and resultant clinical trials evaluating immunomodulatory therapies. The purpose of this article is to assess potential proinflammatory targets and review the safety and efficacy of immunomodulatory therapies in managing patients with acute respiratory distress syndrome associated with coronavirus disease 2019.

The Brain

Intravascular lymphomatosis is an uncommon lymphoproliferative disorder characterised by intravascular distribution of neoplastic lymphoid cells (B- or T- lymphocites), what leads to occlusion of small vessels and causes signs and simptoms of disorder. Its initial predilection sites are the brain or the skin, and hematopoetic organs are usually spared. The signs and symptoms of the disorder are attributed to vascular occlusion. Clinical course is fatal, besides therapy. In our case disorder has started with partial epileptic seizures with secondary generalisation, and after that with motor aphasia, right hemi paresis, urinary incontinence and cognitive changes. She was hospitalized for several times, completely investigated, but with no conclusion. Seven months after appearance of symptoms, she died. And diagnosis was determined at autopsy. A myriad of neurological and systemic manifestations are putting us in an unequal position with this fatal disease. Early diagnosis can increase survival and decrease intensity of symptoms. So every new case is important as warning that we must not forget about this disease.

Abstract ObjectiveThe objective of this study was to identify the predictors of in-hospital mortality among patients with diffuse alveolar hemorrhage (DAH).Patients and MethodsWe conducted a retrospective review of 89 patients hospitalized for DAH at our institution between 2001 and 2017: 49 patients who died during hospitalization and 40 patients who survived were compared. We reviewed their presenting signs and symptoms, clinical course, radiologic and pathologic findings, along with medical management. We then performed univariate and multivariate analyses to identify the risk factors associated with in-hospital mortality.ResultsWe identified 12 factors to be associated with mortality when comparing survivor vs non-survivor cohorts: smoking (27 [67%] vs 21 [42%], p = 0.02), malignancy (7 [17%] vs 24 [49%], p = 0.002), interstitial lung disease (0 vs 7 [14%], p = 0.01), liver failure (1 [2%] vs 14 [28%], p = 0.001), autoimmune diseases (16 [40%] vs 4 [8%], p =0.0006), thrombocytopenia (3 [7%] vs 35 [71%], p <0.0001), ICU admission (23 [57%] vs 40 [85%], p=0.004), mean duration of ICU stay (3.5 days [± 6.7] vs 5.5 days [± 5.5], p = 0.4), steroid use (36 [90%] vs 31 [63%], p = 0.003), use of plasma exchange (6 [15%] vs 0, p = 0.005), use of mechanical ventilation (15 [37%] vs 36 [75%], p value = 0.0007) and development of acute respiratory distress syndrome (ARDS) (9 [22%] vs 37 [77%], p <0.0001), respectively. On multivariate analysis, thrombocytopenia (OR 52.08: 95% CI, 8.59-315.71; p <0.0001) and ARDS (OR 11.71: 95% CI, 2.60-52.67; p = 0.0013) were associated with higher odds of mortality in DAH while steroid use (OR 0.05: 95% CI, 0.007-0.39; p = 0.0004) was associated with a lower risk of in-hospital mortality in patients with DAH.ConclusionIn DAH, thrombocytopenia and ARDS were predictors of in-hospital mortality whereas the use of steroid was associated with a more favorable prognosis.

Abstract Objectives We planned this study to determine the clinical spectrum and compare incidence of multiorgan dysfunction in children hospitalized with scrub typhus with other etiologies of tropical fever. Design Prospective cohort study. Setting Pediatric emergency and PICU services of a university teaching hospital situated in the sub-Himalayan region. Patient Children aged 2 months to 14 years with acute undifferentiated fever of more than 5 days. Interventions Detailed fever workup was performed in all children. We compared scrub typhus IgM positive children (cases) with remaining febrile children who were negative for scrub IgM assay (controls) for mortality and morbidity. Main results We enrolled 224 febrile children; 76 children (34%) were positive for scrub typhus IgM ELISA. Scrub typhus group had a significantly higher incidence of multiorgan dysfunction [OR 3.5 (95% CI 2.0–6.3); p &lt; 0.001] as compared to non-scrub typhus group requiring supportive care. The incidence of altered sensorium [OR 8.8 (95% CI 3.1–24.9)], seizures [OR 3.0 (95% CI 1.1–8.3)], acute respiratory distress syndrome [OR 17.1 (95% CI 2.1–140.1)], acute renal failure (5% vs. 0%), meningitis [OR 6.2 (95% CI 1.2–31.6)], thrombocytopenia [OR 2.8 (95% CI 1.5–5.1)], transaminitis [OR 2.7 (95% CI 1.6–4.8)], requirement of oxygen [OR 17.8 (95% CI 4.0–80.3)], positive pressure support [OR 3.7 (95% CI 1.2–10.5)] and shock requiring inotropes [OR 3.0 (95% CI 1.3–6.7)] was significantly higher in scrub typhus group as compared to the non-scrub typhus group (Table 1). Conclusions Pediatric scrub typhus who were hospitalized had severe systemic manifestations when compared to other causes of fever.
