Scleroderma Renal Crisis (SRC) is a life-threatening complication of systemic sclerosis (SSc), traditionally associated with anti-RNA polymerase III antibodies, corticosteroid use, and diffuse skin involvement. However, the role of COVID-19 as a potential trigger for SRC remains poorly understood. This study explores the occurrence of COVID-19-associated SRC, focusing on its clinical presentation, underlying risk factors, and outcomes.
We present a case series of two unvaccinated patients with systemic sclerosis who developed SRC following COVID-19 infection, despite the absence of traditional risk factors. Clinical features, laboratory findings, renal histopathology, and disease progression were analyzed to assess potential mechanisms linking SARS-CoV-2 infection to SRC onset. Both patients developed abrupt-onset malignant hypertension and acute kidney injury after supporting the COVID-19. Neither patient had a history of corticosteroid use or known anti-RNA polymerase III positivity, suggesting an alternative mechanism of SRC activation. Notably, both cases had pre-existing renal anomalies (renal developmental abnormality and prior nephrectomy), which may have contributed to increased susceptibility. Despite aggressive management, both patients developed dialysis-dependent renal failure and succumbed to SRC-related complications.
Our findings highlight COVID-19 as a potential trigger for SRC, possibly through endothelial dysfunction, inflammatory cytokine storms, and renal microangiopathy. The presence of pre-existing kidney conditions may further predispose SSc patients to SRC following SARS-CoV-2 infection. Additionally, the lack of vaccination in these cases raises the question of whether COVID-19 immunization could reduce SRC risk. Further research is needed to elucidate the pathophysiology, risk stratification, and long-term outcomes of COVID-19-associated SRC, as well as the role of vaccination in prevention.
Chronic kidney disease (CKD) is a major and growing global public health problem, contributing to significant morbidity, mortality, and financial strain on healthcare systems. Despite available preventive measures, CKD often remains underdiagnosed and insufficiently addressed by health policies worldwide.
A literature review was conducted using the MEDLINE electronic database via PubMed, Scopus, and the HINARI (Research4Life) program, focusing on studies published since 2001. Search terms included “primary care”, “chronic kidney disease”, “chronic kidney disease public health”, and “chronic kidney disease costs”. Original articles, meta-analyses, and systematic reviews were included, with English-language articles prioritized. Bibliographic references of selected publications were also examined to identify additional relevant studies.
CKD affects approximately 700-850 million people globally, with rising prevalence and mortality rates, especially in low- and middle-income countries. The disease disproportionately burdens vulnerable populations and health systems due to high direct and indirect costs, particularly for advanced-stage care. While cost-effective prevention and early detection strategies are available, their implementation is uneven, and policy responses have historically lagged. Successful national initiatives demonstrate that early intervention and integrated care can reduce the incidence and economic impact of end-stage kidney disease.
CKD is a preventable, yet increasingly prevalent disease that requires urgent public health action. Prioritizing early detection, integrated care models, and policy reforms can significantly curb its global burden. Coordinated efforts at international, national, and local levels are essential to translate existing knowledge into effective practice and reduce the societal and financial costs of CKD.
Autoimmune hemolytic anemia occurs due to the accelerated destruction of erythrocytes as a result of the dysfunction of immune system cells, which produce antibodies against the normal antigens of the membrane of hematopoietic cells. One of its causes is systemic lupus erythematosus.
We present a case of a 20-year-old patient who was hospitalized with acute autoimmune hemolytic anemia, having been diagnosed with SLE at the age of 18 years. At the onset of the disease, hemolytic anemia was a differential diagnostic challenge.
The differential diagnosis between primary and secondary autoimmune hemolytic anemia (AIHA) was an important step. The presence of antinuclear antibodies (ANA Hep2, Anti-dsDNA, Anti-cardiolipin, Anti-phospholipids, anti-Ro, Anti-Sm B) were important arguments in making the diagnosis. The relapse of AIHA was caused by inadequate treatment, due to a lack of compliance. Pulse therapy combined with methylprednisolone and cyclophosphamide successfully resolved the AIHA.
Hematological abnormalities are commonly seen in SLE patients, but hemolytic autoimmune anemia is a rare condition. A timely diagnosis of the cause of hemolytic anemia and proper treatment of lupus by correcting autoimmune disorders are crucial in disease management. Pulse therapy combined with corticosteroids and immunosuppressants is effective in acute relapses of hemolytic anemia.
Pachydermoperiostosis (or primary hypertrophic osteoarthropathy) is a rare genetic disease that usually begins in childhood or adolescence, is characterized by certain clinical signs (pachydermia, periostosis, drum sticks) that gradually progress over many years until the disease stabilizes. Currently, there are 2 genes in which mutations are associated with the development of pachydermoperiostosis - HPGD and SLCO2A1. The functions of these genes are not fully understood, but their influence on the metabolism of prostaglandin E2 is known.
We present a case of a 20-year-old patient mistakenly diagnosed as juvenile idiopathic arthritis. Symptoms on admission to the hospital: pain accompanied by swelling in the hands and feet, arthralgias in the talocrural joints, knees with slight swelling, paresthesia in the extremities, hyperhidrosis, fatigue. Clinical and paraclinical examinations confirmed the diagnosis of pachydermoperiostosis.
Pachydermoperiostosis should be considered as a differential diagnosis when a patient presents with hypertrophic osteoarthropathy and acromegalic features.
The incidence and prevalence of gout have increased worldwide in recent decades. Scientists at the Rochester Epidemiology Project (MN, USA) have seen a two-fold increase in the incidence of primary gout (patients without diuretic exposure) over a 20-year period, which ended in 1996. The increase of incidence may be related due to the difficulty and often unsatisfactory treatment options. The aim of the study was to systematize the recommendations on dietary treatment, and medication for patients with gout.
An analytical, qualitative, and secondary study was performed in the form of a synthesis article. 115 sources were identified and analyzed; from this list, 44 sources were selected according to the impact score during the publication period and according to the level of recommendations.
44 articles were included. Most studies were small, retrospective analyses performed in single centers, with concerns for bias. Eleven studies (including five randomized controlled trials) reported improved patient outcomes following pharmacological interventions with known efficacy in gout, including allopurinol, prednisolone, NSAIDs and anakinra. Eight studies reported improved outcomes associated with non-pharmacological interventions: inpatient rheumatology consultation and a hospital gout management protocol. No studies to date have prospectively evaluated strategies designed to prevent re-admissions of patients hospitalized for gout flares.
Urate crystals is completely soluble when we can lower the serum level of uric acid to normal values, but this often requires long-term treatment. The early onset of rehabilitation of affected joints helps to reduce the articular inflammatory process, the pain syndrome and it delays the progression of the underlying pathology while improving the quality of life in patients with gout. Further research is needed to enable healthcare providers to individualize and optimize gout treatment strategies, ensuring that patients with gout receive effective, safe, and high-quality care.
Vitamin D plays an important role in maintaining musculoskeletal health. As the glomerular filtration rate decreases, vitamin D deficiency also occurs. The aim of this paper is to highlight the level of vitamin D depending on the stage of chronic kidney disease.
A structured search was performed in the PubMed, Scopus and HINARI databases, where the relevant articles have been taken into account, published in the last 20 years. The search terms used (in English) were: „vitamin D deficiency”, „pathogenesis of vitamin D”, ”the impact of vitamin D in chronic kidney disease”, „chronic kidney disease”.
Several studies have shown that the change in vitamin D levels is dependent to the decrease of glomerular filtration rate. The lowest serum vitamin D concentration was observed in stage 5 of chronic kidney disease. Vitamin D deficiency occurs due to a decrease in the number of nephrons and a decrease in the number of proximal tubular cells that absorb vitamin D (25 (OH) D) to be subsequently hydroxylated to its active form by 1α-hydroxylase.
Patients with vitamin D-deficient due to chronic kidney disease have an increased risk of decreased bone mineral density and multiple fractures.
Description of two clinical cases with gout and renal involvement, one male and one female, which were hospitalized in the „Timofei Mosneaga” Republican Clinical Hospital and Municipal Clinical Hospital „Saint Trinity” in 2021.
The male patient was hospitalized in a serious condition, being drowsy, disoriented and with bradyphrenia. Patient complained of dyspnea at mild exertion, severe fatigue, 5-day anuria and generalized edema. From the history collected from relatives, it was discovered that the patient has been diagnosed with gout a few years ago. The female patient has been hospitalized in the Nephrology department of the Republican Clinical Hospital „Timofei Moşneaga” for comprehensive evaluation. Her complaints: low back pain, dysuria, nocturia, moderate ankle edema, oliguria, marked asthenia, paresthesia.
In women, primary renal damage is more common until the onset of menopause. After the onset of menopause, there is primarily joint damage, then kidney damage, or this process develops simultaneously (kidney and joint damage). In males due to hyperuricemia, there is joint damage, which later is associated with gouty nephropathy or kidney and joint involvement evolve paralleled.
