Overview
Renal transplant patients are under immunosuppression to modulate the immune response to graft. Moreover these patients have various underlying chronic kidney diseases and other co-morbidities such as diabetes and hypertension, which can impact the results in COVID-19 infection. Hence these patients are at a higher risk of developing COVID-19 associated complications.[1] The clinical manifestations, treatment and prognosis of COVID-19 infection may be different from the general population.[2] It is believed that any transplant recipient presented to the infection would result in a high level of cases; however the risk of donor to recipient transmission is unknown. The chances of a donor to recipient infection might be affected by exposure of the donor, infectivity of the the donor during the incubation period and the degree of viremia as well as the viability of virus in specific organ system.Hence, in spite of the conceivable negative outcomes, temporary interruption of kidney transplantation might be needed in regions where the rate of infection is high.[3]
Historical Perspectives
The etiological agent involved is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19), first detected in Wuhan, China. On March 12, 2020 the World Health Organization declared the COVID-19 outbreak a pandemic.[4] The earlier SARS epidemic of Hong Kong is known to affect both pediatric and adult renal transplant patients where the severity of disease in adult patients was more than that in pediatric patients[5] The first reported case of COVID-19 infection in renal transplant patient, was a 52‐year‐old man who received living‐related kidney transplantation 12 years for chronic glomerulonephritis, in Wuhan, China. He made a successful recovery and was discharged on day 13.[2]
Classification
Classification of COVID-19 infection in renal transplant patients depends on the severity of COVID-19 manifestations. COVID-19 infection classification according to WHO is following[6]:
Mild Disease | Symptomatic patients meeting the case definition for COVID-19
No pneumonia No hypoxia | |
Moderate Disease | Adolescent or adult
Pneumonia with fever, dyspnea, cough, and fast breathing SpO2 > or = 90% Child Signs of non-severe pneumonia (cough, difficulty breathing, fast breathing or chest indrawing) Fast breathing(breaths/min) <2 months: > or = 60 2-11 months: > or = 50 1-5 years: > or = 40 Diagnosis can be made clinically, Chest Imaging (radiograph, CT scan, Ultrasound) may assist in diagnosis. | |
Severe Disease | Severe Pneumonia | Adolescent or adult
Signs of Pneumonia plus one of following: Respiratory rate > 30 breaths/min Severe Respiratory Distress SpO2 < 90% Child Pneumonia plus at least one of following Central cyanosis or SpO2 < 90% Severe respiratory distress (fast breathing, grunting, severe chest indrawing) General danger signs such as inability to breastfeed or drink, lethargy, or unconsciousness or convulsions Fast breathing(breaths/min) <2 months: > or = 60 2-11 months: > or = 50 1-5 years: > or = 40 Diagnosis can be made clinically, Chest Imaging (radiograph, CT scan, Ultrasound) may assist in diagnosis. |
Critical Disease | Acute Respiratory Distress Syndrome (ARDS) | Onset: within 1 week of pneumonia or new worsening respiratory symptoms.
Chest imaging: (radiograph, CT scan, or lung ultrasound): bilateral opacities, not related to volume overload, lobar or lung collapse, or nodules Origin of pulmonary infiltrates: Respiratory failure not explained by cardiac failure or fluid overload. Oxygenation impairment in adults: -Mild ARDS: 200 mmHg < PaO2/FiO2a ≤ 300 mmHg (with PEEP or CPAP ≥ 5 cmH2O) -Moderate ARDS: 100 mmHg < PaO2/FiO2 ≤ 200 mmHg (with PEEP ≥ 5 cmH2O) -Severe ARDS: PaO2/FiO2 ≤ 100 mmHg (with PEEP ≥ 5 cmH2O) Oxygenation impairment in children: note OI and OSI. Use OI when available. If PaO2 not available, wean FiO2 to maintain SpO2 ≤ 97% to calculate OSI or SpO2/FiO2 ratio: • Bilevel (NIV or CPAP) ≥ 5 cmH2O via full face mask: PaO2/FiO2 ≤ 300 mmHg or SpO2/FiO2 ≤ 264. • Mild ARDS (invasively ventilated): 4 ≤ OI < 8 or 5 ≤ OSI < 7.5. • Moderate ARDS (invasively ventilated): 8 ≤ OI < 16 or 7.5 ≤ OSI < 12.3. • Severe ARDS (invasively ventilated): OI ≥ 16 or OSI ≥ 12.3. |
Sepsis | Adults:
Acute life-threatening organ dysfunction caused by a dysregulated host response to suspected or proven infection. Signs of organ dysfunction: altered mental status, difficult or fast breathing, low oxygen saturation, reduced urine output, fast heart rate, weak pulse, cold extremities or low blood pressure, skin mottling, laboratory evidence of coagulopathy, thrombocytopenia, acidosis, high lactate, or hyperbilirubinemia. Children Suspected or proven infection and ≥ 2 age-based systemic inflammatory response syndrome (SIRS) criteria, of which one must be abnormal temperature or white blood cell count. | |
Septic shock | Adults:
Persistent hypotension despite volume resuscitation, requiring vasopressors to maintain MAP ≥ 65 mmHg and serum lactate level > 2 mmol/L Children: Any hypotension (SBP < 5th centile or > 2 SD below normal for age) or two or three of the following: altered mental status; bradycardia or tachycardia (HR < 90 bpm or > 160 bpm in infants and heart rate < 70 bpm or > 150 bpm in children); prolonged capillary refill (> 2 sec) or weak pulse; fast breathing; mottled or cool skin or petechial or purpuric rash; high lactate; reduced urine output; hyperthermia or hypothermia |
Pathophysiology
Genetics
Angiotensin-converting enzyme 2 and Dipeptidyl peptidase have been implicated in the uptake of SARS-Cov and MERS-CoV[7][8] Several studies have indicated that viral S-protein RBD interacts with host ACE2 receptor. S protein changes thus make the human cells permissive to SARS-CoV and SARS-CoV-2 infection[9] [10] [11] [12] [13]ACE2: ACE ratio is higher in the kidneys compared to the respiratory system. (1:1 in the kidneys VS 1:20 in the respiratory system).[14]These receptors are found in the proximal tubules of kidney[7][8]SARS-CoV2 spike(S) protein is cleaved and activated by transmembrane serine protease family (TMPRSS) after attaching to angiotensin-converting enzyme 2 (ACE2) receptors. This allows the virus to release fusion peptide that aides in membrane fusion..[15]
